Differential shell hole machining device for bevel gear and using method

Abstract

The invention discloses a differential shell hole machining device for a bevel gear. The differential shell hole machining device comprises a connecting plate, a clamp body, a spring expansion piece,a pull rod, a compression cap and a cushion block. The clamp body is installed at the right side of the connecting plate through a connecting bolt I; a cylindrical positioning shaft is formed at the right end of the clamp body; the spring expansion piece and the compression cap sleeve the positioning shaft in sequence; the right end of the pull rod is fixed to the compression cap and is flush withthe right side of the compression cap, and the left end of the pull rod sequentially penetrates through the clamp body and a shaft hole of the connecting plate and extends out of the left side of theconnecting plate; and the cushion block is connected to the right end surface of the clamp body through a connecting bolt II. The device can solve the problems of out-of-tolerance of coaxiality of aleft differential shell hole and a right differential shell hole and machining instability in the process due to influences of clamping jaw precision and clamping and positioning deviations in the original machining scheme, the coaxiality requirement of the left differential shell hole and the right differential shell hole is effectively ensured, the machining quality in the process is stable, andthe machining efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a bevel gear differential shell hole processing device and a using method. Background technique [0002] Since the gear is a key component in the automobile axle, it mainly serves to transmit the high-speed rotational motion of the transmission shaft to the high-speed rotational motion of the tires on both sides through the meshing of active and passive bevel gear pairs, so the assembly accuracy is required to be high. Bevel gear inner hole processing, especially gear inner hole processing with left and right differential shell holes, requires high coaxiality and dimensional machining accuracy of left and right differential shell holes. In order to ensure the coaxiality requirements of the left and right differential shell holes of the gear, the commonly used clamping scheme is to process the left differential shell hole first, then use the three-jaw ...

Problems solved by technology

[0003] The purpose of the present invention is to process the left difference shell hole first in the processing process of the existing bevel gear, and then locate it with three claws, and process the right difference shell hole with the left difference shell hole as a reference positioning method, resulting in left and right The coaxiality of the differential shell hole is out of tolerance, which affects the assembly accuracy of the whole bridge. A bevel gear differential shell hole processing device and its use method are provided, which can effectively ensure the machining accuracy and quality of the left and right differential shell holes of the processed gear. Stable, fast and convenient loading and unloading, high processing efficiency
