Description

Technical Field

[0001] The utility model belongs to the technical field of pressure-holding jigs, and more specifically, it relates to a product pressure-holding jig. Background Technique

[0002] A pressure-holding jig is a tool used to keep workpieces or equipment under specific pressure in various industrial and production environments. The design and application of this jig aim to ensure that during machining, installation, or other operations, the workpiece can be stably and safely fixed, while avoiding displacement or damage caused by pressure changes.

[0003] When the existing pressure-holding jig clamps and fixes the workpiece, the clamping force is not uniform enough, and it is difficult to control the clamping force. When the clamping force of the pressure-holding jig is too large, it is easy to damage the outer wall of the workpiece, and when it is too small, it is easy to loosen. Moreover, since the shapes of the workpieces to be clamped are different, it is easy to cause the workpiece to be stressed unevenly and unstably, which greatly affects the construction efficiency. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a product pressure-holding jig, which has the advantages of stable and uniform clamping force.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A product pressure-holding jig, including a mounting plate. There is a mounting part on the top of the mounting plate. A sliding hole is provided in the mounting part. A pneumatic rod one is provided on the back end face of the mounting part. A clamping part one is provided at the end of the pneumatic rod one. The clamping part one passes through the sliding hole. A fixing block one and a fixing block two are respectively provided on the front end face of the mounting part. A number of sliding rods are provided between the fixing block one and the fixing block two. A clamping part two is provided on the side of the sliding rod away from the clamping part one.

[0007] On the end faces of the clamping part one and the clamping part two close to each other, a mounting block one and a mounting block two are respectively provided. A rack one is provided on the end face of the mounting block one close to the mounting block two.

The gear meshes with the rack one and the rack two respectively;

[0008] One end of the clamping part one and the clamping part two are respectively provided with a clamping plate one and a clamping plate two. On the side of the mounting plate away from the mounting part, there is a pneumatic rod two. The end of the pneumatic rod two is provided with a clamping plate three.

[0009] The advantages of this solution are at least as follows: During use, first, according to the size of the product, the controller is used to control the clamping plate three on the pneumatic rod two to fix the product. Then, the controller is used to send an instruction to the pneumatic rod one. The pneumatic rod one drives the clamping part one, so that the rack one and the rack two provided on the mounting block one and the mounting block two are meshed with the gear, enabling the clamping part one and the clamping part two to approach or move away from each other, thereby driving the clamping plate one and the clamping plate two to further clamp the product. According to the fixing situation of the product, the pneumatic rod three can continue to be started through the controller, so that the pneumatic rod three drives the clamping plate four to fix the top position of the product. Through the mutual cooperation of the clamping plate one, the clamping plate two, the clamping plate three and the clamping plate four, the present utility model can not only clamp the product evenly in all aspects, and the uniform distribution of the clamping force can ensure the stable position of the workpiece during the processing, reduce the displacement and deformation of the workpiece caused by uneven clamping, thereby improving the processing accuracy, but also enable the fixture to clamp products of different sizes, thereby improving the applicable range and reducing the production cost.

[0010] The present utility model is further configured as: On the front end surface of the mounting part, there are a plurality of round grooves. Inside the round grooves, there are compression springs. The end of the compression spring is provided with a clamping plate five.

[0011] The advantages of this solution are at least as follows: By providing the compression spring and the clamping plate five, the compression spring can provide the necessary elastic force to ensure that the clamping plate can effectively contact the object to be clamped and maintain a certain pressure. This design helps to improve the stability and repeatability of the fixture, because the spring can automatically adjust the pressure according to the shape and size of the object to be clamped.

[0012] The present utility model is further configured as: Rubber sheets are provided on the end surfaces of the clamping plate four and the clamping plate three.

[0013] The advantages of this solution are at least as follows: By providing the rubber sheet, the rubber material has good elasticity and friction, can provide stable support when clamping the part, and at the same time avoid damaging the inner wall of the part due to direct contact.

[0015] The advantages of this solution are at least as follows: By providing a sliding groove and a slider, the cooperation between the slider and the sliding groove can achieve more precise positioning of the clamping plate three for the product, prevent the clamping plate three from loosening due to long-term use, and improve the clamping efficiency.

[0016] The present utility model is further configured such that: anti-slip patterns are provided on the end faces of the mutually approaching sides of the clamping plate one and the clamping plate two.

[0017] The advantages of this solution are at least as follows: By providing anti-slip patterns, the friction force between the clamping plate and the workpiece can be significantly increased. This increased friction force helps to improve the stability of the workpiece in the fixture, reduce the displacement of the product during clamping, and thus improve the machining accuracy and surface quality.

[0018] The present utility model is further configured such that: a limiting portion is fixedly provided in the middle of the sliding rod.

[0019] The advantages of this solution are at least as follows: By providing a limiting portion, the wear of the gears caused by the frequent or out-of-design-range movement of the clamping portion one and the clamping portion two can be reduced, thereby avoiding mechanical damage caused by unexpected situations.

[0031] Clamping parts one 5 and two 9 are respectively provided with clamping plates one 13 and two 14 at their ends. On the side of the mounting plate 1 away from the mounting part 2, there is an air rod two 15. At the end of the air rod two 15, there is a clamping plate three 16. On the top of the mounting part 2, there is a mounting bracket 17. On the side of the mounting bracket 17 away from the mounting part 2, there is a round hole. Inside the round hole, there is an air rod three 18 fixedly connected. The lower end face of the air rod three 18 is connected with a clamping plate four 19. On the top of the mounting plate 1, there is a controller 20. The controller 20 is electrically connected to the air rod one 4, the air rod two 15, and the air rod three 18. When in use, first, according to the size of the product, the controller 20 is used to control the clamping plate three 16 on the air rod two 15 to fix the product. Then, the controller 20 is used to send an instruction to the air rod one 4. The air rod one 4 drives the clamping part one 5, so that the rack one and rack two provided on the mounting block one 10 and the mounting block two 11 are meshed with the gear 12, enabling the clamping part one 5 and the clamping part two 9 to approach or move away from each other, thereby driving the clamping plates one 13 and two 14 to further clamp the product.

[0032] As Figure 2 shown, several round grooves are provided on the front end face of the mounting part 2. Inside the round grooves, there are compression springs 21. At the end of the compression springs 21, there are clamping plates five 22. By providing the compression springs 21 and the clamping plates five 22, the compression springs 21 can provide the necessary elastic force to ensure that the clamping plates can effectively contact the object to be clamped and maintain a certain pressure.

[0035] As Figure 1 shown in the figure, anti-slip patterns are provided on the end faces of the first clamping plate 13 and the second clamping plate 14 that are close to each other. By providing the anti-slip patterns, the friction between the clamping plate and the workpiece can be significantly increased.

[0036] As Figure 3 shown in the figure, limiting parts 26 are fixedly provided in the middle of the sliding rods 8. By providing the limiting parts 26, the wear of the gear 12 caused by the frequent or excessive movement of the first clamping part 5 and the second clamping part 9 beyond the design range can be reduced, thereby avoiding mechanical damage caused by unexpected situations.

[0037] The working process and beneficial effects of the present utility model are as follows: When in use, first, according to the size of the product, the controller 20 is used to control the third clamping plate 16 on the second air rod 15 to move towards the fifth clamping plate 22 to fix the product. Then, the controller 20 is used to issue an instruction to the first air rod 4, and the first air rod 4 drives the first clamping part 5, so that the first rack and the second rack provided on the first mounting block 10 and the second mounting block 11 are engaged with the gear 12, enabling the first clamping part 5 and the second clamping part 9 to approach or move away from each other, thereby driving the first clamping plate 13 and the second clamping plate 14 to further clamp the product. According to the fixing situation of the product, the third air rod 18 can continue to be started through the controller 20, so that the third air rod 18 drives the fourth clamping plate 19 to fix the top position of the product. Through the mutual cooperation of the first clamping plate 13, the second clamping plate 14, the third clamping plate 16 and the fourth clamping plate 19 of the present utility model, not only can the product be evenly clamped in all aspects, but the uniform distribution of the clamping force can ensure the stable position of the workpiece during the machining process, reduce the displacement and deformation of the workpiece caused by uneven clamping, thereby improving the machining accuracy, but also the fixture can clamp products of different sizes, thereby improving the applicable range and reducing the production cost.
