Description

Technical Field

[0001] This utility model belongs to the field of tooling for mechanical processing equipment, and specifically relates to a pneumatic clamp for drilling and milling of irregularly shaped clamps. Background Technology

[0002] Irregularly shaped clamps are a special type of clamp, typically used to fix and connect pipes or equipment of various irregular shapes. Therefore, irregularly shaped clamps have relatively thin walls, making them prone to deformation during processing. Currently, drilling and milling are performed in separate steps, involving multiple clamping operations. Lathes are used to machine the inner holes and end faces, while milling machines machine the bottom surfaces. Due to their thin walls, these clamps are extremely prone to deformation during clamping, making it impossible to guarantee machining accuracy and relative positional accuracy. Furthermore, manual clamping with calipers means that the force applied by the same person each time and by different people will vary slightly, further compromising the accuracy of the irregularly shaped clamps during processing and affecting the quality of the finished product. Additionally, the numerous clamping operations in separate steps result in low production efficiency and high costs. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a pneumatic clamp for drilling and milling of irregularly shaped clamps that is simple in structure, has high production efficiency, ensures the dimensional accuracy of workpiece drilling and milling, and can simultaneously drill and mill.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A pneumatic clamp integrating drilling and milling with a special-shaped clamp includes a base plate. The base plate has an air passage, an air inlet / outlet hole 1 and an air inlet / outlet hole 2 on its front vertical surface, a limiting block 1 on the front left side of the base plate, a limiting block 2 on the rear left side of the base plate, a fixed support seat 1 on the front left side of the base plate, a fixed support seat 2 in the middle of the front front of the base plate, an elastic lateral clamping post seat 1 on the upper right side of the base plate, an elastic lateral clamping post 1 on the elastic lateral clamping post seat 1, and a cylinder seat 2 on the front right side of the base plate. A pneumatic telescopic cylinder 2 is installed on the cylinder seat 2, and the front end of the pneumatic telescopic cylinder 2 is... There is a top rod 2, and on the base plate corresponding to the top rod 2, there is an elastic lateral locking pin 2, and on the elastic lateral locking pin 2, there is an elastic lateral locking pin 2; on the right rear end of the base plate, there is a cylinder seat 1, on which a pneumatic telescopic cylinder 1 is installed, and at the front end of the pneumatic telescopic cylinder 1, there is a top rod 1, on the base plate corresponding to the top rod 1, there is a contour-following limiting support block, on the base plate between limiting block 1 and limiting block 2, there is an adjustable support seat 1, on the base plate between limiting block 1 and elastic lateral locking pin 2, on the base plate between elastic lateral locking pin 2 and contour-following limiting support block, there is an adjustable support seat 3, and on the base plate between contour-following limiting support block and limiting block 2, there is a fixed support seat 3.

[0005] The beneficial effects of this utility model are as follows: The integrated pneumatic clamp for drilling and milling of irregular-shaped clamps replaces the existing manual clamping of irregular-shaped clamps in drilling and milling processes with integrated pneumatic pressure clamping of irregular-shaped clamps. This combines the two processes into one, reducing the number of clamping operations. A single clamping operation ensures the required positional accuracy. Simultaneously, the pneumatic clamping design controls the clamping force, ensuring no deformation of the workpiece before and after processing, thus guaranteeing the accuracy of the finished product. The air circuit is built into the base plate, eliminating connecting pipes between cylinders, reducing unused space in the clamp, and facilitating clamp installation and disassembly.

Detailed Implementation

[0009] Example, see attached document Figure 1 , 2An air passage is provided within the base plate 1. Air inlet / outlet 1-1 and air inlet / outlet 1-2 are located on the front face of the base plate 1. A limiting block 2 is located on the front left side of the base plate 1, and a limiting block 3 is located on the rear left side of the base plate 1. Limiting blocks 2 and 3 limit the workpiece 21 to prevent it from moving freely. A fixed support base 5 is located on the left front side of the base plate 1, and a fixed support base 9 is located on the right side of the fixed support base 5. Fixed support bases 5 and 9 are used to fix the position of the workpiece 21. An elastic lateral locking pin seat 6 is located on the upper right side of the fixed support base 5 on the base plate 1, and an elastic lateral locking pin 4 is installed on the elastic lateral locking pin seat 6. A cylinder seat 2 12 is provided on the front right side of the base plate 1. A pneumatic telescopic cylinder 2 10 is mounted on the cylinder seat 2 12. A telescopic rod push rod 2 11 is provided at the front end of the pneumatic telescopic cylinder 2 12. A cylinder seat 1 16 is provided on the rear right side of the base plate 1. A pneumatic telescopic cylinder 1 17 is mounted on the cylinder seat 16. A telescopic rod push rod 19 is provided at the front end of the pneumatic telescopic cylinder 17. Push rod 19 and push rod 2 11 are mainly used to clamp the workpiece 21. A contour-following limiting support block 18 is provided on the base plate 1 corresponding to push rod 19. The shape of the contour-following limiting support block 18 matches the shape of the workpiece 21 it contacts, further improving the tightness between the workpiece 21 and the contour-following limiting support block 18 and improving the stability during processing. On the base plate 1 corresponding to the top rod 211, there is an elastic lateral locking pin seat 23, and on the elastic lateral locking pin seat 213, there is an elastic lateral locking pin 24. The top cylinders of the elastic lateral locking pin 14 and the elastic lateral locking pin 24 can swing, and due to the built-in spring, they can generate a lateral reset force. On the base plate between the limiting block 12 and the limiting block 23, there is an adjustable support seat 17, and on the base plate 1 between the limiting block 12 and the elastic lateral locking pin seat 213, there is an adjustable support seat 28. On the base plate 1 between the elastic lateral locking pin seat 213 and the contour limiting support block 18, there is an adjustable support seat 35. Since the shape of each batch of workpieces is different due to casting problems, the height of the support position is adjusted according to the batch during processing. The adjustable support seat 17, adjustable support seat 28 and adjustable support seat 35 can adjust the height of the support position of the workpiece 21 to ensure that the workpiece is placed horizontally. A fixed support seat 20 is provided on the base plate 1 between the contouring limit support block 18 and the limit block 2 3 to fix the workpiece 21.

[0010] The working process of this utility model is as follows: When using the irregular clamp drilling and milling integrated pneumatic clamp, the workpiece 21 is placed on the fixed support seat 1 5, fixed support seat 2 9 and fixed support seat 3 20 of the clamp. The fixed limiting side 1 21-5 of the workpiece 21 is in close contact with the limiting block 1 2. The fixed limiting side 2 21-6 of the workpiece 21 is in close contact with the limiting block 2 3. The outer shape limiting side 21-2 of the workpiece 21 is in close contact with the contour limiting support block 18. The elastic lateral clamping post 1 4 and the elastic lateral clamping post 2 14 clamp the workpiece 21. For the first piece of each batch of blanks, adjust the adjustable support base 7, adjustable support base 8, and adjustable support base 20 to ensure the workpiece 21 is in a horizontal position. Then, air enters through air inlet 1-1. The push rod 19 of pneumatic telescopic cylinder 17 and the push rod 111 of pneumatic telescopic cylinder 20 extend to clamp the workpiece 21. After clamping the workpiece 21, drilling and milling can be performed, specifically machining the inner ring hole 21-1, end face 21-3, and bottom face 21-4. After machining, air enters through air inlet 1-2, and the push rod 19 of pneumatic telescopic cylinder 17 and the push rod 111 of pneumatic telescopic cylinder 20 retract, unloading the workpiece 21, thus completing the entire work process. The above work process can be repeated, with repeated clamping and machining.
