[0002] Inspection fixtures can quickly and accurately measure and inspect the size, shape, and position parameters of products, ensuring that products meet design requirements and quality standards. By using inspection fixtures, manufacturers can promptly identify product quality problems during the production process and take corresponding measures to adjust and improve them, thereby improving product production efficiency and quality stability.

[0003] The inspection fixture for hole symmetry is a device specifically designed to detect the symmetry of holes on various parts. The holes on the parts need to meet strict symmetry requirements, which directly affects the assembly accuracy and overall performance of the product. This inspection fixture can accurately measure the deviation between the actual position of the hole and the ideal symmetrical position, providing key quality data for the production process.

[0004] Traditional inspection fixtures are designed for holes of specific shapes and sizes. When inspecting the symmetry of holes in workpieces of different specifications and shapes, the fixtures need to be redesigned and manufactured, resulting in high costs and low efficiency. Existing technologies design inspection fixtures into modular structures, which can adapt to the inspection needs of different workpieces and holes through the combination and adjustment of different modules. However, there will be errors in the connection between modules, which will reduce the overall accuracy and reduce the accuracy of the inspection results. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fixture for detecting the symmetry of holes, aiming to improve the problem that errors in the connection between modules in the prior art lead to a decrease in overall accuracy and a reduction in the accuracy of the detection results.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fixture for detecting the symmetry of a hole, comprising two clamping blocks, each clamping block having a slot on an adjacent side, and each slot having a limiting groove on its left and right sides. The inner walls of the two slots are slidably connected to the same detection platform. The front and rear ends of the left and right sides of the detection platform are fixedly connected to fixing plates. Multiple fixing plates are fixedly connected to the other side of their respective fixing plates, and the other ends of multiple telescopic rods are fixedly connected to top plates. Multiple top plates are respectively fixedly connected to the inner walls of their corresponding slots. The front and rear ends of the left and right sides of the detection platform are fixedly connected to limiting blocks, which are slidably connected within their respective limiting grooves. Each clamping block has a detection block fixedly connected to an adjacent side. The bottom of the two clamping blocks is provided with a fixing mechanism for fixing the fixture.

[0007] As a further description of the above technical solution:

[0008] The fixing mechanism includes a base, which is disposed at the bottom of the two clamping blocks. Multiple support blocks are fixedly connected to the top front and rear sides of the base. Corresponding support plates are fixedly connected to the top of the multiple support blocks. Multiple sliding rods are fixedly connected to the adjacent side of the two support plates. Multiple sliding grooves are opened at the bottom of the two clamping blocks. The multiple sliding rods are slidably connected to the inner wall of the corresponding sliding groove. The same reinforcing rod is fixedly connected to the middle of the multiple sliding rods.

[0009] As a further description of the above technical solution:

[0010] A second limiting groove is provided on the top of the rear clamping block, and a positioning plate is slidably connected inside the second limiting groove.

[0011] As a further description of the above technical solution:

[0012] Each of the two clamping blocks has a flexible support pad fixedly connected to an adjacent side, and both flexible support pads are made of gel material.

[0013] As a further description of the above technical solution:

[0014] A controller is fixedly connected to the top of the front clamping block, and the controller is electrically connected to multiple telescopic rods respectively.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the controller controls the extension rod to move the clamping block. The clamping blocks located on both sides of the detection table move to the appropriate position, and the extension rod retracts to control the clamping blocks on both sides to retract towards the middle. If the holes on both sides of the workpiece are symmetrical, the detection block can be inserted into the hole of the workpiece. Otherwise, it indicates that the holes on both sides of the workpiece are asymmetrical. This realizes the detection of the symmetry of holes of workpieces of various sizes and specifications. The accuracy of the detection results is high and can meet different production needs.

[0023] 2. In this utility model, the sliding rod is slidably connected to the sliding groove at the bottom of the clamping block, which provides a guiding function for the sliding of the clamping block and ensures that the clamping block can only slide along the direction of the sliding rod. The reinforcing rod is fixedly connected to the sliding rod, which enhances the overall structural strength and stability of the sliding rod. During the sliding process of the clamping block, the reinforcing rod can effectively prevent the sliding rod from shaking, deforming and shifting, thus ensuring the reliability and accuracy of the fixing mechanism.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a tooling for detecting the symmetry of a hole, comprising two clamping blocks 1, each clamping block 1 having a slot 3 on an adjacent side, and each slot 3 having a limiting groove 4 on the left and right sides of its inner wall. The inner walls of the two slots 3 are slidably connected to the same detection platform 5. The front and rear ends of the left and right sides of the detection platform 5 are fixedly connected to fixing plates 6. The other side of each fixing plate 6 is fixedly connected to a telescopic rod 7, and the other end of each telescopic rod 7 is fixedly connected to a top plate 9. The top plates 9 are respectively fixedly connected to the inner walls of the corresponding slots 3. The front and rear ends of the left and right sides of the detection platform 5 are fixedly connected to limiting blocks 8, and the limiting blocks 8 are slidably connected inside the corresponding limiting grooves 4. Each adjacent side of the two clamping blocks 1 is fixedly connected to a detection block 10. The bottom of the two clamping blocks 1 is provided with a fixing mechanism 2 for fixing the tooling.

[0033] Specifically, when using the inspection fixture for hole symmetry, the dimensions of the workpiece to be inspected are first input into the controller 14. The controller 14 controls the extension rod 7 to extend and push the top plate 9 in front of it. The top plate 9 then moves the clamping blocks 1. The clamping blocks 1 located on both sides of the inspection table 5 move to the appropriate positions. The limiting blocks 8 connected to the inspection table 5 move in the limiting groove 4. The limiting groove 4 limits the limiting blocks 8, and thus limits the inspection table 5. The workpiece is positioned and limited by adjusting the positioning plate 12 located inside the limiting groove 11. At this time, the workpiece is positioned on the inspection table 5. Then, the extension rod 7 is retracted to control the clamping blocks 1 on both sides to retract towards the middle. If the holes on both sides of the workpiece are symmetrical, the inspection block 10 can be inserted into the holes of the workpiece. Otherwise, it indicates that the holes on both sides of the workpiece are asymmetrical. This realizes the inspection of hole symmetry of workpieces of various sizes and specifications. The inspection results are highly accurate and can meet different production needs.

[0034] Reference Figure 1 , Figure 3 and Figure 5The fixing mechanism 2 includes a base 201, which is located at the bottom of two clamping blocks 1. Multiple support blocks 202 are fixedly connected to the front and rear sides of the top of the base 201. The top of the multiple support blocks 202 is fixedly connected to a corresponding support plate 203. Multiple sliding rods 204 are fixedly connected to adjacent sides of the two support plates 203. Multiple sliding grooves 205 are opened at the bottom of the two clamping blocks 1. The multiple sliding rods 204 are slidably connected to the inner wall of the corresponding sliding groove 205. The middle of the multiple sliding rods 204 is fixedly connected to the same reinforcing rod 206.

[0035] Specifically, when the fixture for detecting the symmetry of the inspection hole needs to be fixed, the base 201 acts as a basic support, providing a stable support platform for the entire device. The support block 202 is fixed on the top of the base 201, supporting the support plate 203 and placing it at a suitable height and position. The slide rod 204 is fixed on the support plate 203 and cooperates with the slide groove 205 at the bottom of the clamping block 1, providing guidance for the sliding of the clamping block 1 and ensuring that the clamping block 1 can only slide along the direction of the slide rod 204, limiting its displacement in other directions. The reinforcing rod 206 is fixed in the middle of the multiple slide rods 204, connecting the multiple slide rods 204 into a whole, enhancing the overall structural strength and stability of the slide rods 204. During the sliding process of the clamping block 1, the reinforcing rod 206 can effectively prevent the slide rods 204 from shaking, deforming, and shifting, ensuring the reliability and accuracy of the fixing mechanism 2.

[0036] Reference Figure 1 , Figure 2 and Figure 5 The rear clamping block 1 has a limiting groove 2 11 on its top. A positioning plate 12 is slidably connected inside the limiting groove 2 11 to provide more precise positioning support for the workpiece placed on the clamping block 1. Flexible support pads 13 are fixedly connected to the adjacent sides of the two clamping blocks 1. Both flexible support pads 13 are made of gel material to avoid scratching and damage to the surface of the workpiece caused by hard contact. A controller 14 is fixedly connected to the top of the front clamping block 1. The controller 14 is electrically connected to multiple telescopic rods 7. Triangular blocks 15 are fixedly connected to one side of multiple support blocks 202. The bottom of multiple triangular blocks 15 is fixedly connected to the top of the base 201 to provide fixed support. Connecting blocks 16 are fixedly connected to the top left and right sides of the reinforcing rod 206. The top of the two connecting blocks 16 is fixedly connected to the bottom of the detection table 5. Buffer pads 17 are fixedly connected to one side of multiple limiting grooves 1 4. Multiple buffer pads 17 are slidably connected to the corresponding limiting blocks 8.

[0037] Specifically, the positioning plate 12 can slide to different positions within the limiting groove 11 according to actual needs, providing more precise positioning support for the workpiece placed on the clamping block 1. The flexible support pad 13 is made of gel material, which has good flexibility and cushioning performance. When the clamping block 1 clamps the item, the flexible support pad 13 can closely fit the surface of the item, avoiding scratches and damage to the surface of the item caused by hard contact. The controller 14 is electrically connected to multiple telescopic rods 7, realizing intelligent control of the telescopic rods 7. The operator can conveniently adjust the extension and retraction state of the telescopic rods 7 through the controller 14. The triangular block 15 utilizes the stability principle of triangles to enhance the connection strength and stability between the support block 202 and the base 201. When the clamping block 1 moves, the buffer pad 17 can provide cushioning protection.

[0038] Working principle: When using the inspection fixture for hole symmetry, the dimensions of the workpiece to be inspected are first input into the controller 14. The controller 14 controls the extension rod 7 to push the top plate 9 in front of it. The top plate 9 drives the clamping block 1 to move. The clamping blocks 1 on both sides of the inspection table 5 move to the appropriate position. The limiting block 8 connected to the inspection table 5 moves in the limiting groove 1 4. The limiting groove 1 4 limits the limiting block 8, and then limits the inspection table 5. By adjusting the positioning plate 12 located inside the limiting groove 2 11, the workpiece is positioned and limited. At this time, the workpiece is positioned on the inspection table 5. Then, the extension rod 7 is retracted to control the clamping blocks 1 on both sides to retract towards the middle. If the holes on both sides of the workpiece are symmetrical, the inspection block 10 can be inserted into the hole of the workpiece. Otherwise, it means that the holes on both sides of the workpiece are not symmetrical. This realizes the inspection of hole symmetry of workpieces of various sizes and specifications. The inspection results are highly accurate and can meet different production needs.

[0039] Furthermore, when the fixture for detecting the symmetry of the inspection holes needs to be fixed, the base 201 acts as a basic support, providing a stable support platform for the entire device. The support block 202 is fixed on the top of the base 201, supporting the support plate 203 and placing it at a suitable height and position. The sliding rod 204 is fixed on the support plate 203 and cooperates with the sliding groove 205 at the bottom of the clamping block 1, providing guidance for the sliding of the clamping block 1 and ensuring that the clamping block 1 can only slide along the direction of the sliding rod 204, limiting its displacement in other directions. The reinforcing rod 206 is fixed in the middle of multiple sliding rods 204, connecting multiple sliding rods 204 into a whole, enhancing the overall structural strength and stability of the sliding rods 204. During the sliding of the clamping block 1, the reinforcing rod 206 can effectively prevent the sliding rods 204 from shaking, deforming, or shifting, ensuring the reliability and accuracy of the fixing mechanism 2.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
