Abstract

The utility model relates to a clamping tool used for machine work, particularly a clamping tool used for grinding circular arc surfaces of cutter bodies of ball head milling cutters. The utility model is characterized in that the utility model comprises a clamping tool body, a clamping pipe sleeve fixedly connected to the clamp tool body, a clamping pipe and a draw rod, wherein, a conical hole is arranged in the clamping pipe sleeve, and a conical outer wall matching with the conical hole on the clamping pipe sleeve is arranged on the outer wall surface of the clamping pipe. The draw rod is in transmission connection with the clamping tool body by a threaded rod, and one end of the draw rod is inserted into the clamping pipe and is in threaded connection with the clamping pipe. The automatic centering expanding clamp of the utility model enables the rotating center of a grinded milling cutter is overlapped with the center of a ball head of the grinded milling cutter when the milling cutter is processed to solve the regeneration of abandoned ball head milling cutters. Besides, the utility model has the advantages of simple structure, convenient manufacture, convenient use, etc.

Description

The self-centering of the grinding rose cutter folder that rises

The utility model relates to the special fixture that a kind of machined is used, especially a kind of self-centering that is used for the arc surface of grinding rose cutter cutter hub folder that rises.

The rose cutter that processing alley arc surface is adopted uses its edges dull of back long-term, and the arc surface work in-process of cutter hub will touch processed alley arc surface, not only influences processing but also influence product quality, even can't process down; As continuing to use this rose cutter, just need the arc surface of its blade of grinding and cutter hub, but can't grinding utilize again at present, so it can only be scrapped because of lacking the anchor clamps that a kind of center that can guarantee its pivot and milling cutter bulb coincides.So not only waste raw material, but also strengthened the processing charges of alley arc surface.

The purpose of this utility model is to overcome the shortcoming that exists in the above-mentioned prior art, a kind of self-centering that can be used for the grinding rose cutter of grinding rose cutter cutter hub arc surface folder that rises is provided, overlap with its bulb center so that be ground the pivot of milling cutter, thereby solve the regeneration of the rose cutter that goes out of use, and make it have characteristics such as simple in structure, that manufacturing is easy and easy to use.

The self-centering of the utility model grinding rose cutter folder that rises, be characterized in: it contains clamp body, be fixed in clamp, a pull bar of having the conical outer wall that the round taper hole that puts with clamp is complementary on the clamp cover of band round taper hole on the clamp body its, its outside wall surface, this pull bar is connected with screw drive with clamp body, and the one end insert clamp, with clamp to be threaded.To realize that clamp can clamp or unclamp the rose cutter in it in moving axially.

The self-centering of the utility model grinding rose cutter folder that rises can have a handle, to make things convenient for the rotation of pull bar on its pull bar.

The utility model has the advantages that: 1) the utility model self-centering folder that rises makes and is ground the pivot of milling cutter in grinding process and overlaps with its bulb center all the time, thereby solve the regeneration of the rose cutter that goes out of use, saved the raw material of making rose cutter, the processing cost that has reduced the alley circular arc widely; What 2) the utility model self-centering was risen and pressed from both sides is simple in structure, easily manufactured; 3) when using the utility model self-centering to rise by folder, if with its clamp body insert grinding carriage, milling cutter to be ground is put into clamp, rotating tension bar get final product then, so easy to use and save time and laborsaving.

Below will be by embodiment, and the contrast accompanying drawing, the utility model is done narration further.Accompanying drawing thes contents are as follows:

Fig. 1 is the main cutaway view that the self-centering of the utility model grinding rose cutter is risen and pressed from both sides;

Fig. 2 is its left view.

The rise structure of folder of the self-centering of the utility model grinding rose cutter can see from Fig. 1 and Fig. 2, and it contains the clamp 3 that has the conical outer wall that the round taper hole that puts with clamp is complementary on 2, its outside wall surface of clamp cover that a clamp body 1, be fixed in band round taper hole on the clamp body its, a pull bar 4.

Clamp body 1 can insert on the head of a bed that is fixed on grinding machine, and it and clamp cover 2 are with bolt 21 affixed being integral.Clamp 3 is rich in plasticity (this plasticity can be provided with longilineal groove or select for use plastic material to realize by the generatrix direction at the conical outer wall of clamp), its kink is in good rigidly, the clamp cover 2 that can not be out of shape, when its does moving axially to the right, its conical outer wall can be squeezed, produce distortion, thereby clamps the rose cutter and the automatic centering heart (Fig. 1 represents rose cutter with double dot dash line) that places in it.Pull bar 4 and clamp body 1 are connected with screw drive, and the one end insert clamp 3, with clamp to be threaded.Rotating tension bar can spur clamp 3 by the screw drive mechanism between it and the clamp body and move to the left or to the right, thereby unclamps or clamp rose cutter.

The utility model self-centering rise the folder pull bar 4 on can have a handle 5, to make things convenient for the rotation of pull bar.

When the self-centering of using the utility model grinding rose cutter rises by folder, earlier self-centering is risen and press from both sides in the head of a bed that inserts grinding machine, again rose cutter to be processed is put into clamp 3 (Fig. 1 represents it with double dot dash line), rotating rod 4 moves right clamp 3 then, rose cutter is clamped and automatic centering, can start grinding machine rose cutter cutter hub arc surface this moment; Grinding finishes, and then the reverse rotation pull bar 4, and clamp 3 is moved to the left, and rose cutter is released, unload.

Claims

1, a kind of self-centering of grinding rose cutter folder that rises, it is characterized in that: it contains clamp (3), a pull bar (4) that has the conical outer wall that the round taper hole that puts with clamp is complementary on clamp cover (2) that a clamp body (1), one be fixed in band round taper hole on the clamp body its, its outside wall surface, this pull bar is connected with screw drive with clamp body (1), and the one end insert clamp (3), with clamp to be threaded.

2, the self-centering of the grinding rose cutter as claimed in claim 1 folder that rises is characterized in that: can have a handle (5) on the said pull bar (4).
