[0017] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Reference Figures 1 to 5 This utility model provides a multi-station side-top clamp, comprising a mounting base 1, a first clamping part, and a second clamping part. The first clamping part includes a first clamping block 2, which is fixed to the middle of the mounting base 1. The second clamping part includes several second clamping blocks 3, arranged in a row and located on one side of the first clamping part. Each second clamping block 3 is slidably connected to the mounting base 1. The second clamping blocks 3 and the first clamping blocks 2 are opposite to each other, and a clamping groove can be formed between them. One or more second clamping blocks 3 can be selected for clamping according to the size and shape of the workpiece and actual usage requirements. After adjusting the second clamping blocks 3 to an appropriate position, the workpiece is placed and the second clamping blocks 3 are slidable, so that the workpiece is clamped in the clamping groove. Compared with the prior art, the clamp in this application has stronger adaptability and is convenient for clamping parts of various shapes and sizes.

[0019] Specifically, the second clamping block 3 includes a clamping part 31, a connecting part 32, and an adjusting screw 33. A limiting groove 111 is provided on one side of the mounting base 1. The connecting part 32 is embedded in the limiting groove 111. The clamping part 31 faces the first clamping block 2. A threaded hole 113 is provided in the limiting groove 111. The adjusting screw 33 passes through the clamping part 31 and connects to the threaded hole 113. By rotating the adjusting screw 33, the clamping part 31 can slide, thereby adjusting the space of the clamping groove. The specific implementation of the adjusting screw 33 is described in detail below: The adjusting screw 33 includes a head and a rod. The rod passes through a through hole 321, and a stop plate is fitted onto the rod passing through the through hole 321. The stop plate abuts against the side wall of the connecting part 32. The combined limiting effect of the head and the stop plate confines the adjusting screw 33 to the connecting part 32, preventing the adjusting screw 33 from sliding in the radial direction of the through hole 321 and allowing it to rotate only within the through hole 321. In this embodiment, to facilitate the installation of the stop plate, a retaining spring 34 is used. The side wall of the rod of the adjusting screw 33 has a connecting groove 331. The retaining spring 34 can be fitted onto the rod through elastic deformation and then embedded in the connecting groove 331. After the rod of the adjusting screw 33 is inserted into the threaded hole 113, rotating the adjusting screw 33 allows it to be screwed in or out of the threaded hole 113. At this time, the adjusting screw 33 is rotatably connected to the through hole 321. The retaining ring 34 limits the axial movement of the adjusting screw 33 along the through hole 321, so that the connecting part 32 can slide in the limiting groove 111 as the adjusting screw 33 rotates.

[0020] Furthermore, the mounting base 1 is provided with a guide rail 112, and the clamping part 31 is partially embedded in the guide rail 112 and slidably connected to the guide rail 112.

[0021] Specifically, the guide rail 112 is located above the limiting groove 111, and the width of the guide rail 112 is greater than the width of the limiting groove 111. After the connecting part 32 is installed and embedded in the limiting groove 111, a portion of the bottom of the clamping part 31 is embedded in the guide rail 112. Through the limiting effect of the guide rail 112, the clamping part 31 slides along the straight direction of the guide rail 112, thereby accurately abutting against the first clamping block 2, facilitating the clamping of the parts. In this embodiment, the adjusting screw 33 is an internal hex screw, which can be tightened and loosened using a hex wrench. Simply insert the long end of the L-shaped internal hex wrench to operate the adjusting screw 33 within a narrow space with a very small range of wrench movement, which is very flexible.

[0022] The limiting groove 111 itself has a limiting and guiding function, so the guide rail 112 structure can be eliminated. In the above embodiment, the guide rail 112 is provided to further enhance the movement accuracy of the clamping part 31, so that the clamping part 31 accurately holds the first clamping block 2.

[0023] Furthermore, the second clamping part consists of two sets, with the first clamping block 2 arranged in a strip shape, and the two sets of second clamping parts located on both sides of the long side of the first clamping block 2 respectively.

[0024] Specifically, the mounting base 1 includes a mounting part 11 and a support part 12. The mounting part 11 is located at the top of the support part 12 and is used to connect the first clamping part and the second clamping part. The mounting part 11 has a square structure, and the first clamping block 2 has a strip-shaped structure. The first clamping block 2 is installed in the middle of the mounting part 11, leaving space on both sides of the mounting part 11 for the second clamping part to be installed. This fixture has dual-station clamping capabilities, allowing irregularly shaped parts to be placed on both stations for double-sided clamping and fixing. Alternatively, parts can be clamped on both stations for batch processing. Both the first and second clamping parts are detachably connected to the mounting base 1. The size and shape of the first and second clamping parts can be customized according to actual usage requirements, and they can be replaced on the mounting base 1.

[0025] The support part 12 is also provided with a connecting slot 121, which makes it convenient for the support part 12 to be installed in the designated position of the machine tool equipment.

[0026] In this embodiment, the second clamping part includes a plurality of second clamping blocks 3 arranged in a row and located on one side of the first clamping part. Each of the second clamping blocks 3 is slidably connected to the mounting base 1. The second clamping blocks 3 are disposed opposite to the first clamping blocks 2, and a clamping groove can be formed between them. One or more second clamping blocks 3 can be selected for clamping according to the size and shape of the workpiece and actual usage requirements. After adjusting the second clamping blocks 3 to an appropriate position, the workpiece is placed and the second clamping blocks 3 are slid, so that the workpiece is clamped in the clamping groove. Compared with the prior art, the fixture in this application has stronger adaptability and is convenient for clamping parts of various shapes and sizes.

[0027] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
