Abstract
The utility model discloses a clamping device for friction welding machine, including rotatory (holding) chuck, first profile modeling anchor clamps, second profile modeling anchor clamps and spacing ejector pin, first profile modeling anchor clamps and second profile modeling anchor clamps set up on rotatory (holding) chuck, utilize the first profile modeling anchor clamps of rotatory (holding) chuck drive and second profile modeling anchor clamps to open and close, form after first profile modeling anchor clamps and second profile modeling anchor clamps close and hold the chamber with weldment complex, during friction welding, spacing ejector pin tightly pushes up at the rear end face of first profile modeling anchor clamps and second profile modeling anchor clamps. By arranging the first profiling fixture and the second profiling fixture and forming the accommodating cavity matched with the special-shaped part inside, the clamping is integrated, and the special-shaped part and the fixtures are prevented from moving in a crossing manner; and the rear end face of the clamp is in contact with the surface of the limiting ejector rod, so that the upsetting force is borne more uniformly, and the parts, the main shaft clamp and the internal parts are prevented from being damaged due to the final friction upsetting force. And further improve the quality and the precision of the welded special-shaped parts.
Description
Technical Field
The utility model relates to a friction welding field, in particular to a clamping device for friction welding machine.
Background
The traditional friction welding limiting ejector rod needs to be attached to the rear end face of a part, if the rear end face of a special-shaped part is an inclined plane, the limiting ejector rod cannot be attached or is not attached tightly, and finally, due to the fact that the friction upsetting is large in force, parts in a spindle clamp can be damaged in a severe mode, even the spindle clamp and spindle parts can be affected, and welding accuracy is seriously affected.
SUMMERY OF THE UTILITY MODEL
To the defect that prior art exists above, the utility model discloses a main aim at overcomes prior art's weak point, discloses a clamping device for friction welding machine, including rotatory (holding) chuck, first profile modeling anchor clamps, second profile modeling anchor clamps and spacing ejector pin, first profile modeling anchor clamps with second profile modeling anchor clamps set up on the rotatory (holding) chuck, utilize rotatory (holding) chuck drive first profile modeling anchor clamps with second profile modeling anchor clamps are opened and are closed, first profile modeling anchor clamps with second profile modeling anchor clamps form after closing and hold the chamber with weldment complex, during friction welding, spacing ejector pin tightly pushes up first profile modeling anchor clamps with the rear end face of second profile modeling anchor clamps.
Further, the first profiling fixture and the second profiling fixture are of cuboid structures.
Further, the spin chuck is a two-grip chuck.
Further, the two-jaw chuck is 2L _06 in model.
The utility model discloses the beneficial effect who gains:
the utility model is provided with the first profiling fixture and the second profiling fixture, and the inner part of the first profiling fixture is provided with the containing cavity matched with the special-shaped part, so that the first profiling fixture and the second profiling fixture form a whole after clamping, and the special-shaped part and the fixtures are prevented from moving; and the rear end face of the clamp is in contact with the surface of the limiting ejector rod, so that the upsetting force is borne more uniformly, and the parts, the main shaft clamp and the internal parts are prevented from being damaged due to the final friction upsetting force. And further improve the quality and the precision of the welded special-shaped parts.

the reference numbers are as follows:
1. the special-shaped part forming device comprises a rotary chuck, 2, a first profiling fixture, 3, a second profiling fixture, 4, a limiting ejector rod, 5 and a special-shaped part.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
A clamping device for a friction welding machine comprises a rotary chuck plate 1, a first profiling clamp 2, a second profiling clamp 3 and a limiting ejector rod 4, wherein the first profiling clamp 2 and the second profiling clamp 3 are arranged on the rotary chuck plate 1, the rotary chuck plate 1 is used for driving the first profiling clamp 2 and the second profiling clamp 3 to be opened and closed, and a special-shaped part 5 is clamped and fixed through the first profiling clamp 2 and the second profiling clamp 3; wherein, first profile modeling anchor clamps 2 and second profile modeling anchor clamps 3 close the back, and its middle formation holds the chamber with weldment complex, and special-shaped part 5 is installed and is held the intracavity, forms a whole with first profile modeling anchor clamps 2 and second profile modeling anchor clamps 3. During friction welding, the limiting ejector rod 4 tightly abuts against the rear end faces of the first copying clamp 2 and the second copying clamp 3. Axial transmission is guaranteed not to take place to friction weld's upset power reduces the load of rotatory (holding) chuck 1 through acting on spacing ejector pin, and then improves the life of rotatory (holding) chuck 1.
In one embodiment, the first and second contoured clips 2, 3 are rectangular parallelepiped in configuration.
In one embodiment, the spin chuck 1 is a two-grip chuck. Preferably, the model of the two-jaw chuck is 2L _ 06.
The utility model discloses when using, according to the shape of odd-shaped part, select first profile modeling anchor clamps 2 and the second profile modeling anchor clamps 3 of matching to install on rotatory (holding) chuck 1, carry out the centre gripping with the odd-shaped part through rotatory (holding) chuck 1, spacing ejector pin 4 of rethread is decided on the rear end face of first profile modeling anchor clamps 2 and second profile modeling anchor clamps 3 to the upset power when bearing friction welding.
The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
