Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of jaw clamps for friction welding machines, in particular to an anti-deformation device for jaw clamps for friction welding machines. Background Art
[0002] Friction welding machine is a device that uses frictional heat to achieve welding. 1. Working Principle Friction welding machine makes a rotating workpiece contact with another workpiece, generating frictional heat under the action of pressure, so that the material of the contact surface of the workpiece reaches a plastic state. Then the rotation is stopped and upsetting pressure is applied to firmly weld the two workpieces together. Its main process includes the friction heating stage and the upsetting welding stage. 2. Features High-quality welding, high strength of the welded joint can generally reach the same strength as the parent material. The weld quality is good, the structure is dense, and there are no defects such as pores and slag inclusions. The jaws of existing friction welding machines are prone to deformation during use.
[0003] In response to the above-mentioned related issues, during the operation of the friction welding machine, the jaw clamp is mainly responsible for the high-precision, high-pressure clamping task of the welded workpiece. Because the workpiece has to withstand a large axial forging force (ranging from 1 to 200 tons) after clamping during the welding process and must maintain a high clamping accuracy, the jaw clamp is an open mechanical structure, so under a large clamping force, the jaw clamp will produce rigid deformation, thereby affecting the clamping accuracy of the workpiece, and also directly leading to poor accuracy of the workpiece after welding.
[0004] To this end, the utility model provides a jaw clamp anti-deformation device for a friction welding machine to solve the above problems. Utility Model Content

[0017] Beneficial effects
[0018] The utility model provides a device for preventing deformation of a jaw clamp for a friction welding machine. Compared with the prior art, it has the following advantages:
[0019] 1. The friction welding machine uses a jaw clamp anti-deformation device. Through the provided clamping assembly, the jaw clamp can use two horizontally placed oil cylinders to push the moving body inside the jaw to clamp the workpiece under the conventional structure. While clamping the workpiece, the moving body in the jaw will produce an upward deformation trend while bearing the thrust of the clamping cylinder. A tensioning oil cylinder is added to each of the left and right jaw moving bodies. There is a T-nut at the front end of the piston rod of the tensioning oil cylinder, and the T-nut is placed in the T-slot of the jaw base. When the tensioning oil cylinder is not locked, the T-nut at the end of the piston rod can slide freely in the T-slot of the jaw base. When the tensioning oil cylinder is in the locked state, the T-nut at the end of the piston rod will be firmly locked in the T-slot of the jaw base. Under the pulling force of the tensioning oil cylinder, the upward deformation problem of the moving body caused by the external force of the clamping oil cylinder will be offset, thereby ensuring that the jaw clamp can ensure both a larger clamping force and a higher clamping accuracy after clamping the workpiece.
[0020] 2. The anti-deformation device of the jaw clamp of the friction welding machine can provide good support for the bottom of the workpiece through the support assembly, so that the workpiece has a good positioning effect between the clamps, making the positioning work more labor-saving, and can be closed in time when not in use, so that the overall use effect will be better.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0028] The present application will be further described in detail below through the accompanying drawings and examples.
[0029] Reference Figures 1 to 4 The embodiment of the present application provides a jaw clamp anti-deformation device for a friction welding machine, including a jaw clamp base 1, a fixed plate 2 is fixedly installed on the top of the jaw clamp base 1, and a clamping assembly 3 is fixedly installed on one side of the fixed plate 2, the clamping assembly 3 includes a clamping cylinder 31 and a moving body 32, the clamping cylinder 31 is fixedly installed on one side of the fixed plate 2, and the moving body 32 is fixedly connected to the output end of the clamping cylinder 31, a connecting plate 33 is fixedly installed on one side of the moving body 32, a jaw body 34 is fixedly installed on one side of the connecting plate 33, a tensioning cylinder 36 is fixedly installed on the inner side wall of the moving body 32, and a T-nut 37 is fixedly connected to the output end of the tensioning cylinder 36, a jaw base T-slot 38 is opened on one side of the jaw clamp base 1, and a rectangular groove 2 39 is opened on the top of the jaw clamp base 1, and the clamping assembly 3 also includes an anti-slip pad 35, which is bonded to one side of the jaw body 34.
[0030] In this embodiment, the workpiece 7 is first placed in the jaw clamp. After it is placed in place, the clamping cylinder piston in the clamping cylinder 31 moves, and the clamping cylinder piston pushes the two moving bodies 32 to perform center clamping movement, so that the moving body 32 can clamp the workpiece 7 through the jaw body 34. At the same time, the jaw clamp base 1, the jaw clamp front wall 5 and the jaw body 34, and the upper cover 4 form a cavity to ensure the operation accuracy of the moving body 32. When the moving body 32 contacts the workpiece 7, due to the external force of the clamping cylinder 31, the moving body 32 will have an upward deformation tendency during the clamping process. At this time, the tensioning cylinder piston in the tensioning cylinder 36 moves upward together with the T-nut 37. Because the T-nut 37 is restricted in the T-slot 38 of the jaw clamp base 1, the tensioning cylinder 36 moves upward to firmly lock the moving body 5 on the jaw clamp base 1, thereby achieving the jaw clamp while maintaining a large clamping force and ensuring high clamping accuracy.
[0031] Reference Figures 1 to 4 In one aspect of this embodiment, support assemblies 6 are fixedly installed on both sides of the jaw clamp base 1, and the support assembly 6 includes a second fixed plate 61 and an electric push rod 62. The second fixed plate 61 is fixedly installed on both sides of the jaw clamp base 1, and the electric push rod 62 is fixedly installed on the top of the second fixed plate 61. The output end of the electric push rod 62 is fixedly connected to an arc plate 63, and a workpiece 7 is provided on the top of the arc plate 63. The support assembly 6 also includes a slide rod 64, which is fixedly installed on the bottom of the arc plate 63, and the slide rod 64 is slidably connected to the second fixed plate 61.
[0032] In this embodiment, the workpiece 7 is then placed on top of the curved plate 63, and then the electric push rod 62 is started to drive the curved plate 63 to move, so that the workpiece 7 can have a good supporting effect, and the slide rod 64 can make the curved plate 63 move more stably.
[0033] Reference Figures 1 to 4 In one aspect of this embodiment, the jaw clamp front walls 5 are fixedly installed on both sides of the fixed plate 2, and the two jaw clamp front walls 5 are arranged opposite to each other, and the inner side walls of the jaw clamp front walls 5 are fixedly installed with the jaw clamp upper cover plate 4, and the jaw clamp upper cover plate 4 is located above the movable body 32.
[0034] In this embodiment, the jaw clamp upper cover plate 4 and the jaw clamp front wall 5 can provide a better overall anti-deformation effect.
[0035] Working principle: First, the workpiece 7 is placed in the jaw clamp. After it is placed in place, the clamping cylinder piston in the clamping cylinder 31 moves, and the clamping cylinder piston pushes the two moving bodies 32 to perform center clamping movement, so that the moving body 32 can clamp the workpiece 7 through the jaw body 34. At the same time, the jaw clamp base 1, the jaw clamp front wall 5 and the jaw body 34, and the upper cover 4 form a cavity to ensure the operation accuracy of the moving body 32. When the moving body 32 contacts the workpiece 7, due to the external force of the clamping cylinder 31, the moving body 32 will have an upward deformation tendency during the clamping process. At this time, the tensioning cylinder piston in the tensioning cylinder 36 moves upward together with the T-nut 37. Because the T-nut 37 is restricted in the T-slot 38 of the jaw clamp base 1, the tensioning cylinder 36 moves upward to lock the moving body 5 firmly on the jaw clamp base 1, thereby achieving the jaw clamp while maintaining a large clamping force and ensuring high clamping accuracy.
[0036] Then place the workpiece 7 on the top of the curved plate 63, and then start the electric push rod 62 to drive the curved plate 63 to move, so that the workpiece 7 can have a good supporting effect, and the slide rod 64 can make the curved plate 63 move more stably.
