Abstract

The invention particularly relates to a hot-press tooth-aligning clamp for a toothed shaft part and a gear, in order to solve the problems that the positioning is not accurate enough, the clamping force is insufficient and the operation is troublesome during installation of the existing hot-press tooth-aligning clamp for the toothed shaft part and the gear. The hot-press tooth-aligning clamp comprises a base, wherein the base is provided with a counter bore; a positioning sleeve is sleeved at the bottom of the counter bore; a guide shaft I penetrates through the side wall of the base; a step-shaped positioning pin I penetrates through the guide sleeve I; the large-diameter side of the positioning pin I is matched with the inner wall of the guide sleeve I; a spring I is sleeved at the small-diameter side of the positioning pin I; a support plate is fixed at the upper end of the base; a guide sleeve II penetrates through the side wall of the support plate; the position tolerance in the up-down direction of the center lines of the guide sleeve II and the guide sleeve I is smaller than or equal to 0.02mm; a step-shaped positioning pin II penetrates through the guide sleeve II; the large-diameter side of the positioning pin II is matched with the inner wall of the guide sleeve II; and a spring II is sleeved at the small-diameter side of the positioning pin II. The universality is improved, the accuracy and the stability of tooth alignment are ensured, and the hot-press tooth-aligning clamp has the advantages of simple structure and convenience in processing when the operation troublesome extent is reduced.

Description

technical field [0001] The invention relates to a tool for aligning teeth, in particular to a jig for aligning teeth by hot pressing a toothed shaft part and a gear. Background technique [0002] When the existing toothed shaft parts and gears are hot-pressed to install the teeth, semicircular pressure plates are often used for pressing operations. Since the outer circle of the gears is inconsistent with the axial dimensions of the geared shaft parts, the positioning is not accurate enough and the clamping Insufficient power and more cumbersome to operate. Contents of the invention [0003] In order to solve the problems of inaccurate positioning, insufficient clamping force and cumbersome operation when the semicircular pressure plate is used for the installation of the existing toothed shaft parts and gears, a toothed shaft is provided. Parts and gears are hot-pressed tooth-to-tooth fixtures. [0004] The present invention is realized by adopting the following technica...
