This includes cutting tools, fixtures, molds, measuring tools, inspection tools, auxiliary tools, fitter's tools, and workstation fixtures. Tooling is its general abbreviation. Fixtures, also called clamps, are broadly defined as any device used to quickly, conveniently, and safely install workpieces at any stage of the manufacturing process. Examples include welding fixtures, inspection fixtures, assembly fixtures, and machine tool fixtures.
[0003] Currently, a Chinese patent discloses a clamping fixture (authorization announcement number CN208409689U). The first and second quick clamps are respectively equipped with a first pressing part and a second pressing part, which press against opposite sides of the workpiece. A stop block is disposed on the clamping base, used to limit the position of the other two opposite sides of the workpiece. This utility model has a reasonable structure, is easy to operate, has low cost, and is convenient for production. This utility model uses quick clamps to hold the workpiece, making disassembly convenient.

[0004] According to the above reference materials, in the above device, the first and second quick clamps are released, the workpiece is placed in and the placement direction of the workpiece is confirmed, and then the stop block is placed in. The stop block shapes the workpiece and the second pressure bar presses the workpiece to achieve the positioning of the workpiece. However, when the device is used to fix and clamp thin-walled or easily deformable workpieces, the workpiece is prone to deformation, which affects the clamping and processing effect of the device. It is not convenient to clamp the clamping fixture stably and reduces the use effect of the clamping fixture.
[0005] Based on this, the present invention designs a clamping fixture with detection function to solve the above problems. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a clamping fixture with detection function.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A clamping fixture with detection function includes a placement plate, on both sides of the top of the placement plate being slidably connected to mounting blocks, and a clamping mechanism disposed at the top of the placement plate.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] The present invention will be further described below with reference to the embodiments.
[0030] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A clamping fixture with detection function includes a placement plate 1, mounting blocks 2 are slidably connected to both sides of the top of the placement plate 1, and a clamping mechanism 3 is also included. The clamping mechanism 3 is disposed at the top of the placement plate 1. A clamping block 301 is slidably connected to the inner wall of the mounting block 2. A force sensor 302 is installed on one side of the inner wall of the clamping block 301. Two compression springs 303 are disposed between the other side of the clamping block 301 and the inner wall of the mounting block 2. A fixing component 309 is disposed at the top of the placement plate 1.
[0031] When using the clamping fixture, the two mounting blocks 2 move from both sides of the placement plate 1 toward the middle. When the mounting blocks 2 move, they drive the clamping block 301 and the force sensor 302 to move to one side to clamp the workpiece. The compression spring 303 supports the clamping block 301. The force sensor 302 comes into contact with the workpiece. As the mounting blocks 2 move, the force generated between them and the workpiece acts on the force sensor 302. The material inside the force sensor 302 deforms, changing the capacitance value. The force on the force sensor 302 can be detected, and the clamping force generated by the clamping fixture can be detected and adjusted to prevent the clamping fixture from damaging the workpiece.
[0032] In some embodiments, such as Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the clamping mechanism 3 further includes a wire 304 connected to one side of the force sensor 302, one end of the wire 304 being connected to a display screen 305, and the display screen 305 being fixedly connected to one side of the mounting block 2.
[0033] When the force sensor 302 detects the clamping force on the workpiece, the force sensor 302 cooperates with the resistance strain gauge through the wire 304 to detect the clamping force generated on the clamping fixture. The force sensor 302 detects the clamping force generated on the clamping fixture in real time and adjusts the size of the clamping fixture.
[0034] In this embodiment of the utility model, two support blocks 306 are fixedly connected to one side of the clamping block 301 and one side of the inner wall of the mounting block 2, and the two ends of the compression spring 303 are respectively sleeved on the outer walls of the two support blocks 306.
[0035] When the clamping block 301 clamps the workpiece, the two compression springs 303 support the clamping block 301 through the two support blocks 306, thereby improving the clamping effect of the clamping block 301 on the workpiece. The force sensor 302 adjusts the force applied to the clamping block 301 to improve the clamping effect of the clamping fixture.
[0036] In this embodiment of the utility model, a slider 307 is fixedly connected to the bottom end of the mounting block 2, and the slider 307 is slidably connected to the inner wall of the placement plate 1.
[0037] When clamping a workpiece, the mounting block 2 slides within the groove at the top of the placement plate 1 via the bottom slider 307, thereby causing the clamping block 301 to clamp the workpiece.
[0038] In this embodiment of the utility model, a bidirectional lead screw 308 is rotatably connected to the middle of the inner wall of the placement plate 1, and the bidirectional lead screw 308 is disposed on the inner wall of the two sliders 307.
[0039] Manually rotate the bidirectional lead screw 308 so that its two ends are threaded to the two sliders 307 respectively, which drives the two mounting blocks 2 to move from both sides to the middle to clamp and fix the workpiece.
[0040] In this embodiment of the utility model, one end of the bidirectional lead screw 308 extends through the outer wall of the placement plate 1.
[0041] One end of the bidirectional lead screw 308 is located outside the placement plate 1, and it can be rotated to connect with the two sliders 307 by rotating one end of the bidirectional lead screw 308.
[0042] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, the fixing component 309 includes a plurality of evenly distributed mounting grooves 3091 opened at the top of the placement plate 1, and the inner wall of the mounting groove 3091 is provided with an internal thread 3092.
[0043] When clamping the workpiece on the placement plate 1, the mounting groove 3091 on the placement plate 1 can install the limiting block 3093 through its internal thread 3092, so that the limiting block 3093 can limit the workpiece.
[0044] In this embodiment of the utility model, two limiting blocks 3093 are provided at the top of the placement plate 1.
[0045] When clamping a workpiece, the limiting block 3093 is threadedly connected by the internal threads 3092 inside multiple mounting slots 3091. It can be installed in a suitable mounting slot 3091 according to the shape of the workpiece, so as to fix the workpiece in place.
[0046] In this embodiment of the utility model, the mounting groove 3091 is threadedly connected to the limiting block 3093 via the internal thread 3092.
[0047] The limiting block 3093 is threaded into the mounting groove 3091 via the internal thread 3092, which can fix the workpiece.
[0048] In this embodiment of the utility model, a scale 3094 is fixedly connected to the middle of the top of the placement plate 1, and the scale 3094 is disposed on one side of the mounting block 2.
[0049] When the mounting block 2 moves, the scale 3094 on the placement plate 1 can record the moving position of the mounting block 2 and measure the length and width of the workpiece, thereby improving the processing effect of the workpiece.
