Problems solved by technology

Using this relatively primitive manual clamping method, during the multiple clamping process of the ratchet wrench, because the position of the workpiece is different each time, the tool must be set after each clamping, which makes the processing more cumbersome. The machining accuracy is difficult to guarantee, and the machining efficiency is extremely low

Embodiment Construction

[0012] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] As shown in Fig. 1 and Fig. 2, the jig for milling the outer circumference of the present invention includes: a base 1, on which a cylinder 2 and a drive to rotate the rotating shaft 4 in the inner cavity of the cylinder 2 are arranged. The upper cover 14 is arranged on the cylinder body 2, and the lifting oil chamber is opened on the top of the rotating shaft 4, and the lifting piston 9 movably arranged in the lifting oil chamber divides the lifting oil chamber into upper and lower oil chambers, and the upper and lower oil chambers The chamber is dynamic and changes according to the position of the lifting piston 9. A lifting sealing ring is arranged between the side wall of the lifting piston 9 and the wall of the lifting oil chamber. Fixed, the sealing plug 51 arranged at the bottom of the transition shaft 5 is embedded in the liftin...

Abstract

The invention discloses a clamp which is used for milling the outer circumference and can finish the milling and molding by once clamping; the clamp comprises a base; the base is provided with a cylinder and a drive unit for driving a transmission shaft in an inner cavity of the cylinder to rotate; the cylinder is provided with an upper cover; the top of the transmission shaft is provided with a lifting oil cavity; a transition shaft which is movably arranged to penetrate the upper end is fixed with the transmission shaft; the upper and lower parts of the lifting oil cavity are respectively provided with an upper and a lower oil holes; the inner wall of the cylinder is provided with an annular upper and lower oil grooves; the cylinder wall is provided with an upper and a lower oil inlet and outlet channels respectively running through the upper and lower oil grooves; the outward openings of the upper and lower inlet and outlet channels are respectively provided with an upper and a lower oil ports; the transition shaft is sequentially sheathed with a support and a expanding sleeve; a tension rod which is movably arranged to penetrate the expanding sleeve and the transition shaft isfixed with a lifting piston; and the top of the tension rod is provided with a tapered expansion joint which adapts to the expanding sleeve. The clamp of the invention greatly improves the milling precision and efficiency.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture for milling outer circumference. Background technique [0002] At present, when milling the outer circumference of the ratchet wrench at 270°, the workpiece can only be fixed on the workbench with tools such as pressure plates and bolts, and in the process of completing the milling of the outer circumference of the ratchet wrench, it is necessary to perform multiple operations on the ratchet wrench. secondary clamping. Using this relatively primitive manual clamping method, during the multiple clamping process of the ratchet wrench, because the position of the workpiece is different each time, the tool must be set after each clamping, which makes the processing more cumbersome. The processing accuracy is difficult to guarantee, and the processing efficiency is extremely low. Contents of the invention [0003] A technical problem to be solved by the present invention is to provide a fixt...
