A clamping device is arranged on one side of the base, and adjusting devices are arranged between the two sides of the base and the mounting blocks respectively. The clamping device includes a threaded rod, and the threads at both ends of the threaded rod are in opposite directions. A rectangular groove is opened at the top of the base, and the inner wall of the rectangular groove is connected to the outer surface of one end of the threaded rod in a penetrating manner. The outer surfaces of both ends of the threaded rod are threadedly connected with screw hole blocks, and the screw hole blocks are slidably connected to the rectangular groove. A limiting block is fixedly connected to one side of the screw hole block, a plurality of circular grooves are opened on one side of the limiting block, a first spring is fixedly connected to the inner wall of the circular groove, and one end of the first spring is fixedly connected to a limiting rod, and the limiting rod is slidably connected to the circular groove.

[0006] The effects achieved by the above components are as follows: By setting the clamping device, when using a fixture to fix a mechanical part during the machining and production process, according to the size of the mechanical part to be clamped and fixed, manually hold the threaded rod and rotate it in the rectangular groove to a certain angle, then drive the two screw hole blocks and the limit block to move towards each other to a certain position. Then, place the mechanical part on the tops of several limit rods, and then press it downwards, so that the limit rods in contact with the surface of the mechanical part slide downwards in the circular grooves, driving the first spring to contract. And the limit rods that are not in contact on the side fit the surface of the mechanical part according to the shape of the mechanical part. At this time, turn the threaded rod to continue driving the two limit blocks to move towards each other, so that several limit rods will also move towards each other, tightening the limit rods that fit against the side of the mechanical part again to clamp and fix it. By clamping in this way, mechanical parts of different shapes can be clamped and fixed, improving the clamping effect of the fixture and also improving the applicability of the fixture.

A first spring 26 is fixedly connected to the inner wall of the circular groove 25. One end of the first spring 26 is fixedly connected to a limiting rod 27, and the limiting rod 27 is slidably connected to the circular groove 25. When using the fixture to fix a mechanical part during the machining and production process of the mechanical part, according to the size of the mechanical part to be clamped and fixed, manually hold the threaded rod 22 and rotate it in the rectangular groove 21 to a certain angle, then drive the two threaded hole blocks 23 and the limiting block 24 to move in opposite directions to a certain position. Then place the mechanical part on the tops of several limiting rods 27, and then press it downwards, so that the limiting rods 27 in contact with the surface of the mechanical part slide downwards in the circular grooves 25, driving the first spring 26 to contract. And the non-contact limiting rods 27 beside fit the surface of the mechanical part according to the shape of the mechanical part. At this time, screw the threaded rod 22 to continue driving the two limiting blocks 24 to move in opposite directions, so that several limiting rods 27 will also move in opposite directions, and tighten the limiting rods 27 attached to the side of the mechanical part again to clamp and fix it. By clamping in this way, mechanical parts of different shapes can be clamped and fixed, improving the clamping effect of the fixture and also improving the applicability of the fixture.

[0030] Referring to Figure 2 As shown in the figure, in this embodiment, several screwing blocks 28 are fixedly connected to one end of the threaded rod 22, and the several screwing blocks 28 are arranged at equal distances. By providing the screwing blocks 28, the contact area at one end of the threaded rod 22 can be increased, which is convenient for manually holding and screwing it.

[0032] Referring to Figures 3-5As shown in the figure, this embodiment discloses that the adjusting device 3 includes a clamping block 35. Sliding grooves 31 are formed on both sides of the base 1. A sliding hole 32 is formed on one side of the inner wall of the sliding groove 31. One end of the mounting block 4 is slidably connected to the inner wall of the sliding groove 31.

Both ends of the clamping block 35 are respectively inserted into two opposite clamping grooves 33. When the base 1 is installed on the processing equipment for use, according to the installation position and hole distance on the processing equipment to be installed, manually hold the clamping block 35 and pull it outward to a certain position, driving the second spring 34 to stretch. At this time, slide the mounting block 4 and the second spring 34 to one end in the inner walls of the sliding groove 31 and the sliding hole 32 to a certain position, and then release the clamping block 35.

Then, place the mechanical part on the tops of several limit rods 27, and then press it downwards, so that the limit rods 27 in contact with the surface of the mechanical part slide downwards in the circular groove 25, driving the first spring 26 to contract. And the limit rods 27 that are not in contact on the side fit the surface of the mechanical part according to the shape of the mechanical part.
