Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile body/frame modification machine, and more particularly, to an automobile body/frame modification machine for fixing the positional relationship of a front pillar, a center pillar, etc. when modifying an automobile body/frame.

As an example of the above-mentioned conventional automobile body/frame modification machine, there is a known modification tool in which a threaded hole is cut in the axial direction at both ends of a center rod, and a screw member with a clamp for the body/frame is fitted into both threaded holes. . The threaded holes at both ends of this rod have opposite threads, and after both screw members with clamps have been stopped from rotating, the center rod is rotated to adjust the length of the repair tool. However, with this modification tool, it is inefficient to change the length, and the positional relationship of the front pillar etc. is fixed only by one-dimensional tensile force.
There was a problem that the door frame etc. could not be fixed in a two-dimensional shape as a whole.

An object of the present invention is to provide an automobile body/frame modification machine that solves the above-mentioned conventional problems, and its structural feature is that support means are provided in a plurality of radial directions. a plurality of connecting rods having a central coupling member and a first engagement member at one end oriented and supported by the support means and a second engagement member at the other end engaging the body frame; The connecting rod includes a fine adjustment connecting rod that has a fine adjustment section in which two rods are screwed together, and two rods that have a plurality of cross holes are fitted together and a pin is inserted into the cross holes. It consists of two types of coarse adjustment connecting rods that have a coarse adjustment section that maintains the adjusted state. Since the present invention is constructed as described above, firstly, the interval between the engaging members to the body frame can be easily and efficiently adjusted by converting the connecting rods into ones of different lengths. can. The length of the connecting rod can be efficiently adjusted by selecting between a fine adjustment connecting rod and a coarse adjustment connecting rod. Further, by attaching three or more connecting rods to the central coupling device to form a repair machine, it is possible to fix and repair the door frame as a whole two-dimensionally.
By attaching it linearly to the center coupling device, it is possible to fix a door frame, etc. using only one-dimensional tensile force in the same way as the conventional fixing tool described above, but the function is not limited to this. By attaching the two connecting rods to the coupling device so as to cross each other, there is an advantage that the two points to be fixed can be fixed even if there is an obstacle between the two points.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the body/frame modification machine 1 is composed of a central connecting member 2, a fine adjustment connecting rod 4, a coarse adjusting connecting rod 6, and a body engaging member 8. . The central connecting member 2 is disc-shaped and has six radial pairs of pin holes 9 for supporting the connecting rods 4,6.

The fine adjustment connecting rod 4 has a first engaging member 10 that engages with the central connecting member 2, and a lever pin hole 1 at one end.
2 and a first engaging member 14, a pipe member 18 having a female threaded member 16 at the other end, a threaded rod 20 that is threadedly fitted to the female threaded member 16, and a pipe member 18 that is fixed to the threaded rod 20 and is engaged with the body. Pin 2 to mating member 8
and a second connecting member 24 attached via 2. The first engaging portion 10 is U-shaped and has a pair of pin holes 28 into which U-shaped pins 26 are inserted into parallel parts.
A fitting hole 30 is provided in the center of the first engaging portion 10, into which the first connecting member 14 is rotatably fitted. The body engaging member 8 consists of two jaw members 32, a pin 22, and two bolts 34, and the jaw member 32 has a pin hole 33 through which the pin 22 passes and a bolt hole through which the two bolts 34 pass. 36
is provided.

The coarse adjustment connecting rod 6 has a second engaging member 40 that engages with the central connecting member 2, and a second engaging member 40 at one end.
It consists of an outer cylindrical member 44 to which a third connecting member 42 which is rotatably connected to the outer cylindrical member 44 is fixed, a sliding rod 46 that is slidable inside the outer cylindrical member 44, and a U-shaped pin 48. The outer cylinder member 44 and the sliding rod 46 are provided with a plurality of pin holes 50 and 51 through which the U-shaped pin 48 passes. A second connecting member 24 is fixed to the outer end of the sliding rod 46 in the same way as the fine adjustment connecting rod 4.

In the above configuration, the length of the fine adjustment connecting rod 4 is adjusted by rotating the pipe member 18 and the threaded rod 20 relative to each other. To adjust the length of the coarse adjustment connecting rod 6, pull out the U-shaped pin 48, adjust the insertion and removal of the outer cylindrical member 44 and the sliding rod 46, align the pin holes 50 of both, and then insert it again. This is done by inserting a U-shaped pin 48. The length-adjusted adjustment connecting rods 4 and 6 have their pin holes 28 aligned with the pin holes 9 of the central connecting member 2, and the U-shaped pins 26 are inserted therein, as shown in FIG. On the other hand, the body engaging member 8 is connected to the jaw member 32.
A predetermined portion of the body is held between the screws, and the bolt 34 is screwed in to secure the screw to the body. When the above preparations are completed, the pipe member 18 of the fine adjustment connecting rod 4 is
is rotated by a lever (not shown) inserted into the lever pin hole 12, whereby the length of the fine adjustment connecting rod 4 is expanded or contracted to adjust the body.

Another embodiment of the invention is to construct the central connecting member as a rectangular plate, with only two pairs of pin holes arranged in a row for supporting the connecting rods. Although this method provides only one-dimensional correction power, which is called "direct push" or "direct pull" by those skilled in the art, it has the advantage that the device is simple and inexpensive, and is convenient to use as an auxiliary tool for the device of the above embodiment. It is.
