Machining clamp of output shaft of gear case of four-needle-plate opposite-stabbing needle machine

Abstract

The invention relates to the technical field of machining clamps, in particular to a machining clamp of an output shaft of a gear case of a four-needle-plate opposite-stabbing needle machine. The machining clamp of the output shaft of the gear case of the four-needle-plate opposite-stabbing needle machine is provided with a rear clamp body and a front clamp body which are welded by a plate, are subjected to weld inspection and are manufactured by a tempering technology, wherein the front clamp body is fixedly mounted at the position of the right side of the front surface of the rear clamp body; two output shaft holes in the front-back direction are formed in the left side and the right side of the rear clamp body in parallel; a reversing shaft hole in the up-down direction is formed in the front clamp body; a shaft which penetrates in a shaft hole of the right side is in transition connection with a reversing shaft which penetrates in the reversing shaft hole through a bevel gear. By the machining clamp, the machining precision and the machining efficiency of parts are improved.

Description

technical field [0001] The invention relates to the technical field of processing fixtures, in particular to a processing fixture for the output shaft of a gear box of a four-needle plate-to-needle loom. Background technique [0002] The two parallel shafts A and B on the upper part of the gearbox of the four-needle board needling machine and the two parallel shafts on the lower part C and D need to run at the same time to drive the corresponding needle board, so the A shaft, B shaft and C shaft are required The phase difference between the axis and the D axis is less than 20' when running. [0003] However, the keyway phase error of the gearbox of the four-needle plate-to-needle loom currently used by users is relatively large. The keyway of the output shaft is processed indirectly through the tooth-to-tooth relationship. Due to the elimination of the backlash of the gear pair, the box The error of the body processing and the scribing error of the scribing process all affe...

[0003] However, the keyway phase error of the gearbox of the four-needle plate-to-needle loom currently used by users is relatively large. The keyway of the output shaft is processed indirectly through the tooth-to-tooth relationship. Due to the elimination of the backlash of the gear pair, the box The error of the body processing and the scribing error of the scribing process all affect the use accuracy of the final assembly, and the requirements for the use of the upper and lower gearboxes of the four-needle plate paired needle loom cannot be met.
