Description

Technical Field

[0001] This utility model relates to the field of process equipment in the machinery manufacturing industry, and in particular to a lathe fixture for machining multiple holes on a single end face. Background Technology

[0002] A certain workpiece has a compact structure with multiple functional holes equidistant from the center on one end face. Currently, this workpiece is machined using a modular fixture assembled from a set of pre-manufactured standard components and parts. This fixture requires assembly and debugging before use, and is time-consuming in terms of workpiece positioning and clamping. When machining one hole and then machining another hole, repositioning and clamping are required, resulting in low machining efficiency. Milling, on the other hand, cannot directly meet the design drawing requirements.

[0003] Therefore, in order to ensure the quality of finished workpieces and improve the processing efficiency of workpieces, it is necessary to design a lathe fixture for machining multiple holes on a single end face. Utility Model Content

[0004] The purpose of this utility model is to provide a lathe fixture for machining multiple holes on a single end face, so as to reduce the time spent on workpiece positioning and clamping, reduce the conversion time for machining different holes, and solve the problems of long fixture assembly and debugging time and low overall machining efficiency in the existing fixture during the machining preparation process.

[0005] To achieve the purpose of this utility model, the technical solution adopted is as follows: a lathe fixture for machining multiple holes on a single end face, comprising a disc, a support disc, T-bolts, a hook-shaped pressure plate, a hand-operated positioner, a positioning pin, a Y-shaped block, a support plate, a support ball, a screw, and a circular pressure block. The disc is provided with an eccentric boss, which is connected and fixed to the support disc with T-bolts.

[0006] Furthermore, the hook-shaped pressure plate, which is connected by a support plate and a screw and has a support ball and a round pressure block at the joint, has a linkage function when pressing, so that when one end is pressed, the other end is automatically pressed.

[0007] Furthermore, the hook-shaped pressure plates are symmetrically arranged on the support plate, and the workpiece is limited by the positioning pins and V-blocks.

[0008] Furthermore, the disc is provided with multiple positioning holes that match the hand-operated positioner.

[0009] Furthermore, the method employs a hand-operated positioner to rotate the support disc, and changes the machining position of the workpiece hole through the positioning hole on the disc.

[0010] The beneficial effects of this utility model are that the lathe fixture for machining multiple holes on a single end face improves the positioning and clamping structure. The fixture reduces the time spent on assembly, debugging, positioning, and clamping, and avoids potential damage to the workpiece surface during positioning and clamping, thus preventing issues that could affect product quality. To address these problems, this utility model employs a hook-shaped pressure plate for linkage clamping; a hand-operated locator to rotate the support disc, and through the positioning holes on the disc, changes the workpiece hole machining position, reducing workpiece positioning, clamping time, and hole position conversion time. A single positioning and clamping operation can perform machining of multiple holes on a single end face, resulting in low processing costs and high processing efficiency.
