AI Technical Summary
Technical Problem
Existing gear grinding fixtures have poor piston positioning and guiding performance and insufficient stability, which affects service life and machining accuracy.
Method used
The piston is designed with a small-diameter upper section, a large-diameter middle section, and a small-diameter lower section. The combination of a positioning boss, a positioning pin, and a positioning post enhances the positioning stability of the piston, and a sealing ring achieves good sealing performance.
Benefits of technology
This improves the positioning stability and service life of the piston, ensures the stability and accuracy of the machining process, ensures the workpiece is firmly installed and avoids loosening, and improves the quality and efficiency of gear grinding.

Abstract
The gear grinding clamp comprises a body, a base, a tensioning sleeve, a pull rod and a piston, the body is detachably connected with the base, and a piston cavity is formed in the base. A bottom plate covers the lower end of the base, an annular positioning boss is arranged on the upper end face of the bottom plate and extends into the lower end of the piston cavity, and a first sealing ring is arranged between the outer circumferential face of the positioning boss and the inner circumferential face of the piston cavity. The piston comprises a small-diameter upper section, a large-diameter middle section and a small-diameter lower section which are sequentially connected from top to bottom; a second sealing ring and a third sealing ring are respectively arranged between the outer peripheral surfaces of the small-diameter upper section and the large-diameter middle section and the inner peripheral surface of the piston cavity; the small-diameter lower section extends downwards into the positioning boss, and a fourth sealing ring is arranged between the matched circumferential surfaces of the small-diameter lower section and the positioning boss; a positioning hole is concavely formed in the lower end face of the small-diameter lower section, a positioning column is correspondingly and detachably connected to the bottom plate, and the positioning column upwards extends into the positioning hole to form up-down sliding fit; and a first positioning pin is arranged between the large-diameter middle section and the base. The structure has a good piston positioning effect and is stable and reliable in movement.
