Self-adaptive broaching machine feeding plate

Abstract

The invention discloses a self-adaptive broaching machine feeding plate which comprises a base, a transition part, a first positioning rod, a second positioning rod, a sliding plate and a clamping and positioning mechanism. The sliding plate is in sliding connection with the transition part in the length direction of the first positioning rod at the single degree of freedom through the first positioning rod. The transition part is in sliding connection with the base in the length direction of the second positioning rod at the single degree of freedom through the second positioning rod. The first positioning rod is perpendicular to the second positioning rod. A vertical through containing cavity for containing workpieces is formed in the sliding plate. The clamping and positioning mechanism is installed on the sliding plate and used for clamping and positioning the workpieces in the radial direction of the containing cavity. The workpieces can be clamped and positioned in the containing cavity of the sliding plate through the clamping and positioning mechanism, and are positioned in a unified mode in the circumferential direction of the workpieces. Rotation of the workpieces is limited on the condition that the workpieces are allowed to transversely move. The consistency of the relative positions of the workpieces on a workbench is improved, and the machined products are good in structure uniformity and high in percent of pass.

Description

technical field [0001] The invention relates to a tooling, in particular to an adaptive broaching machine feeding plate. Background technique [0002] The tooth drawing process includes two processes of initial drawing and finishing drawing. The initial drawing refers to broaching the gear sleeve blank with no teeth in the inner hole, and the finishing drawing refers to correcting the gear sleeve with teeth in the inner hole to meet the product technical requirements. The feeding plate is a tool used to install the workpiece on the broaching machine table. When the traditional feeding plate is loaded into the workpiece, the workpiece can move freely in any direction for 0-3mm, that is, the circumferential direction and radial direction are not positioned, so The workpiece can move and rotate freely within a certain range. When the gear sleeve is fine-drawn, since the feeding plate has no positioning function for the gear sleeve, it is impossible to guarantee the consistency ...

The feeding plate is a tool used to install the workpiece on the broaching machine table. When the traditional feeding plate is loaded into the workpiece, the workpiece can move freely in any direction for 0-3mm, that is, the circumferential direction and radial direction are not positioned, so The workpiece can move and rotate freely within a certain range. When the gear sleeve is fine-drawn, since the feeding plate has no positioning function for the gear sleeve, it is impossible to guarantee the consistency of the relative position of the workpiece on the workbench during each processing, resulting in processing The product structure uniformity is poor, and the qualified rate is low
