Document Type and Number:
WIPO Patent Application WO/2021/232546
Kind Code:
A1
Abstract:
A work fixture for vibration friction welding of an intake manifold. The work fixture comprises a bottom plate (10), a lower cover support unit (20) and a limiting device (30). The lower cover support unit (20) is provided in the center of the upper end face of the bottom plate (10), and a pair of lateral support bases (11) are formed on the upper end face of the bottom plate (10), wherein the pair of lateral support bases (11) is located at the left and right sides of the lower cover support unit (20), and is arranged in a bilaterally symmetrical manner relative to the lower cover support unit (20). The limiting device (30) comprises a pair of limiting moving blocks (33), wherein the pair of limiting moving blocks (33) are respectively provided on the upper end faces of the pair of lateral support bases (11) in such a manner that same can move left and right, and are arranged in such a manner that same can synchronously move away from or approach each other; a left-right movement recess (330) is formed in one end, which is close to the lower cover support unit (20), of the upper portion of each of the pair of limiting moving blocks (33); a U-shaped upper cover support frame (34), an opening of which faces the lower cover support unit, is elastically provided in the left-right movement recess (330) in such a manner that same moves left and right; limiting lifting air cylinders (36) are fixed on the bottom faces of the limiting moving blocks (33); a vertical limiting inserted rod (361) is fixed at the upper end of a piston rod of each of the limiting lifting air cylinders (36); a vertical limiting insertion hole (340), which fits the vertical limiting inserted rod (361), is formed in the bottom face of the upper cover support frame (34); the vertical limiting inserted rod (361) vertically passes through a lower side wall of the left-right movement recess (330), and is inserted into the vertical limiting insertion hole (340); and when the vertical limiting inserted rod (361) is inserted into the vertical limiting insertion hole (340), the end face, which is close to the lower cover support unit (20), of a longitudinal portion of the upper cover support frame (34) is flush with the end face, which is close to the lower cover support unit (20), of the limiting moving block (33) at the corresponding side.
