DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a surface peeling machine for peeling the surface of a workpiece such as H-section steel.

(Prior art) None.

(Problems to be Solved by the Invention) An object of the present invention is to enable reliable peeling even when the surface of an object to be processed such as H-section steel is curved, and further, vibration of the peeling tool causes peeling. Suppresses transmission to the machine body,
An object of the present invention is to provide a surface peeling machine capable of preventing loosening between constituent parts of the peeling machine body.

Configuration of the Invention (Means for Solving Problems) The present invention has been made in view of the above-mentioned problems, and includes a peeling machine main body, a rotary drive source attached to the peeling machine main body, and In a surface peeling machine, comprising a peeling tool that is connected to a rotary drive source, and comes into contact with a workpiece while rotating with the operation of the rotary drive source to peel the surface of the workpiece, The peeling tool is connected to the rotary drive source in a state of being inclined with respect to the horizontal plane, and a displacement allowance mechanism for allowing displacement of the rotary drive source with respect to the peeler main body is provided between the peeler main body and the rotary drive source. It is a thing.

(Operation) By adopting the above-mentioned means, the present invention allows the peeling tool to uniformly contact the surface of the workpiece even when the surface of the workpiece W is curved. Further, during peeling, vibration generated from the peeling tool is transmitted to the rotary drive source, but the displacement allowance mechanism allows displacement of the rotary drive source with respect to the main body of the peeler. For this reason, vibration is less likely to be transmitted from the rotary drive source to the peeling machine main body, and the peeling machine main body and the rotary drive source are suppressed from vibrating integrally.

Next, the configurations of the elastic coupling 27 and the peeling tool 28 will be described in detail with reference to FIGS.

The elastic coupling 27 includes a drive rotating plate 37 as a plate member fixed horizontally to the output shaft 26 of the reduction gear mechanism 25, and a driven rotating plate 38 as a plate member arranged to face the drive rotating plate 37. And its driven rotary plate 3
On the lower surface of 8, a rotary shaft 40 having a threaded portion 39 at its lower end is provided so as to project. A plurality of pins 41 are provided on the driven rotary plate 38.
Are projectingly arranged at predetermined intervals on the same circumference, and their upper end head portions 41a project from the insertion holes 42 of the drive rotary plate 37 onto the drive rotary plate 37. One of the pins 41
The length of the book (on the right side of FIG. 5) is set to be 1 mm shorter than the other pins 41. Therefore, the driven rotary plate 38 is inclined by α ° with respect to the horizontal plane. Also, both rotating plates 3
Between 7 and 38, the two rotating plates 37 and 38 are attached to each pin 41.
A spring 43 as an elastic member that urges in the direction to separate is wound, and the driven rotary plate 38 can be tilted with respect to the drive rotary plate 37 via the spring 43 and the pin 41, and the vertical direction (FIG. 5). It is movably supported by. A plurality of through holes 44 and 45 are formed in the rotary plates 37 and 38 so as to be located between the pins 41 at predetermined intervals on the same circumference. The tool 28 is designed to allow the passage of chips and the like.

On the other hand, the peeling tool 28 is detachably attached to the threaded portion 39 at the lower end of the rotary shaft 40 via a spacer 46 by a nut 47. Further, the peeling tool 28 is the disc 4
A plurality of grindstones 49 are arranged and fixed to the outer peripheral edge of the lower surface of No. 8, and the peeling tool 28 is rotated in a state in which the grindstones 49 are in contact with the surface of the work W, whereby the work W is processed.
Now, using the surface peeling machine configured as described above,
When peeling the surface of the workpiece W such as H-section steel,
As shown in the figure, when the support base 2 is placed near the processing position on the workpiece W, and the switch 31 on the operation panel 30 is closed to excite the electromagnet 3, the support base 2 is moved to the workpiece W. The column 1 is attracted to the upper surface of the column and the column 1 is erected and fixed at a predetermined position. After that, the rotating arm 4 is rotated around the column 1 by the first operation handle 7, and the second operation handle 29 is used.
Thus, the motor 16 can be easily moved up and down with respect to the support arm 5 via the pair of links 9, so that the peeling tool 28 on the workpiece W can be smoothly moved.

Then, in the state described above, the switch 3 on the operation panel 30
When 2 is closed and the hand switch 33 on the second operation handle 29 is closed, the motor 16 is driven and the peeling tool 28 is rotated via the reduction gear mechanism 25 and the elastic coupling 27. Therefore, this peeling tool 28
The surface of the workpiece W can be peeled off with the rotation of.

As described above, since the driven rotary plate 38 is inclined by α ° with respect to the horizontal plane, the peeling tool 28 attached to the driven rotary plate 38 via the rotary shaft 40 is also inclined. . Therefore, at the time of the above-described peeling process, as shown in FIG. 7, even if the surface of the workpiece W is curved, the edge of the tip of each grindstone 49 of the peeling tool 28 is the workpiece. The curved surface of W can be peeled off evenly.

Furthermore, even when the peeling tool 28 collides with a part of the workpiece W and a shock is applied to the peeling tool 28 during the peeling process, the shock is buffered by the elastic coupling 27. The grindstone 49 of the peeling tool 28 is not damaged or noise is not generated.

Further, the vibration generated from the peeling tool 28 during the peeling process is transmitted to the motor 16, but since the mounting plate 17 is attached to the mounting member 11 so as to be capable of fine movement, both 11 and 17 do not vibrate integrally. Therefore, the vibration of the peeling tool 28 is not transmitted to the rotary arm 4, the support arm 5, the link 9 and the like, and the articulated portions thereof are not loosened.

It should be noted that the present invention is not limited to the above-described embodiment, and modifications can be made without departing from the spirit of the invention, for example, by arbitrarily changing the configuration of the elastic coupling 27.

EFFECTS OF THE INVENTION As described in detail above, the present invention is excellent in that the peeling tool can be reliably peeled even when the surface of the workpiece is curved because the peeling tool is provided so as to be inclined with respect to the horizontal plane. Exert the effect. Further, it is possible to suppress the vibration of the peeling tool from being transmitted to the peeling machine main body and prevent loosening between the components of the peeling machine main body.
