Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. ​

[0022] As shown in Figure 1

[0023] An auxiliary fixture for part machining, comprising a workbench 101.

[0024] In this embodiment: to solve the technical problems existing in the prior art, as disclosed in the background art above, "when the part is clamped and fixed, the part is placed on the workbench 101, and the clamping surface of the part needs to be corresponding to the extrusion surface of the clamping mechanism 2, so that for heavier parts, the position of the part needs to be adjusted, which is more laborious, inconvenient for adjusting the position of the part, increases the labor intensity of the workers, and reduces the use effect of the fixture", in combination with use, this problem is obviously a real problem and is relatively difficult to solve.

[0025] Further:

[0026] As shown in Figures 1-3

[0027] In combination with the above: the outer surface of the workbench 101 is rotatably connected with an annular table 102 through a bearing;

[0028] The annular table 102 is installed with a clamping mechanism 2 for clamping and fixing the part;

[0029] The clamping mechanism 2 comprises a fixed plate 202 fixed on the upper surface of the annular table 102 in a symmetrical arrangement, an adjusting screw 201 threadedly connected to the fixed plate 202 through a threaded hole, and an extrusion plate 204 rotatably connected to one end of the adjusting screw 201 through a bearing;

[0030] The extrusion plate 204 and the fixed plate 202 are fixed with a plurality of telescopic rods 203 arranged in a symmetrical arrangement;

[0031] The workbench 101 is installed with a locking mechanism 3 for limiting the rotation of the annular table 102;

[0032] The locking mechanism 3 comprises two groups of side plates 301 fixed on the surface of the workbench 101 in a symmetrical arrangement, a locking block 302 hinged between the two groups of side plates 301 through a hinge shaft, and a clamping groove 303 opened at the edge of the annular table 102 and matched with the locking block 302;

[0033] The locking block 302 and the side plate 301 are provided with a plurality of tension springs 309 arranged in a symmetrical arrangement;

[0034] The locking block 302 is fixed with a second fixed pin 308 on both sides, the two groups of side plates 301 are fixed with a first fixed pin 307 on the side away from each other, and the two ends of the tension spring 309 are buckled on the second fixed pin 308 and the first fixed pin 307, respectively;

[0035] ​​The surface of the lock block 302 is fixed with an annular hanging buckle 304, and the shaft rod 305 is rotatably connected between the two groups of side plates 301 through a bearing. The surface of the shaft rod 305 is fixed with a hook 306.

[0036] In the embodiment: the auxiliary clamp for machining parts, in use, first place the part on the workbench 101, when the clamping surface of the part does not correspond to the extrusion fixing surface of the clamping mechanism 2, first lift the lock block 302, so that the lock block 302 is separated from the clamping groove 303 of the annular table 102, at this time the lock block 302 drives the tension spring 309 to stretch;

[0037] At this time, the hook 306 is buckled on the annular hanging buckle 304, so as to lock the position of the lock block 302. Through this operation, it is more convenient to rotate the annular table 102, without holding the lock block 302 and rotating the annular table 102 at the same time, thereby improving the use effect of the device;

[0038] When the lock block 302 is separated from the annular table 102, then rotate the annular table 102, thereby driving the clamping mechanism 2 to rotate synchronously, so that the extrusion plate 204 on the clamping mechanism 2 corresponds to the clamping surface of the part, then separate the hook 306 from the annular hanging buckle 304, at this time the tension spring 309 rebounds and shrinks, and drives the lock block 302 to be clamped in the clamping groove 303 again, to lock the position of the annular table 102;

[0039] Then rotate the adjusting screw 201, thereby driving the extrusion plate 204 to move, and the extrusion plate 204 drives the telescopic rod 203 to stretch. Through the setting of the telescopic rod 203, the extrusion plate 204 can be limited, so that the extrusion plate 204 moves more stably. Two groups of extrusion plates 204 can clamp and fix the part;

[0040] Through the above operation, for heavier parts, in order to ensure that the clamping surface of the part corresponds to the extrusion plate 204 of the clamping mechanism 2, it is not necessary to adjust the position of the part, but to adjust the clamping mechanism 2. This process is more time-saving and labor-saving, reduces the labor intensity of workers, improves the use effect of the clamp, and meets the actual use demand.

[0041] The working principle and use process of the utility model: the auxiliary fixture for part machining, when using, first place the part on the workbench 101, when the clamping surface of the part and the extrusion fixed surface of the clamping mechanism 2 do not correspond, first lift the lock block 302, make the lock block 302 and the clamping groove 303 opened in the annular platform 102 separate, at this time the lock block 302 drives the tension spring 309 to stretch, at this time the hook 306 is buckled on the annular hanging buckle 304, thereby locking the position of the lock block 302, through this operation, thereby more conveniently rotate the annular platform 102, do not need to hold the lock block 302, rotate the annular platform 102, thereby improve the use effect of the device, when the lock block 302 and the annular platform 102 separate, then rotate the annular platform 102, and drive the clamping mechanism 2 to rotate synchronously, make the extrusion plate 204 on the clamping mechanism 2 and the clamping surface of the part correspond, then the hook 306 and the annular hanging buckle 304 separate, at this time the tension spring 309 rebounds and contracts, and drive the lock block 302 to be clamped in the clamping groove 303 again, lock the position of the annular platform 102, then rotate the adjusting screw 201, and drive the extrusion plate 204 to move, and the extrusion plate 204 drives the telescopic rod 203 to stretch, through the setting of the telescopic rod 203, the extrusion plate 204 can be limited, make the extrusion plate 204 more stable during movement, through two extrusion plates 204, the part can be clamped and fixed, through the above operation, thereby for the heavier part, in order to ensure that the part to be clamped surface and the extrusion plate 204 of the clamping mechanism 2 correspond, thereby do not need to adjust the position of the part, through adjusting the clamping mechanism 2, this process is more time-saving and labor-saving, reduce the labor intensity of the staff, improve the use effect of the clamp, satisfy the actual use demand.
