Description

Technical Field

[0001] This utility model belongs to the technical field of machine tool processing and accessories, and in particular relates to a bearing seat horizontal milling machine mating surface fixture. Background Technology

[0002] When machining the mating surface of the inner ring of a bearing housing, the main precision requirements are concentrated on the relationship between the inner diameter and the position of the locating groove. A vertical CNC milling machine is generally used to machine this mating surface. The machining position datum is usually based on the end face datum, using an inner centering machining process. However, existing manufacturing processes are prone to positional deviations, resulting in scrapped parts or requiring individual machining, increasing manufacturing costs. The deviation of each part's process datum is greatly related to the operator's skill level and tool setting datum, increasing human error. Clamping efficiency is low, personnel skill requirements are high, and shift production efficiency cannot be improved. Summary of the Invention

It avoids clamping errors, calibration errors, machining offsets, and installation defects inherent in vertical milling machines. It is beneficial for subsequent assembly and post-assembly machining, resulting in uniform allowances in the final precision boring of bearing holes. On a horizontal machine tool, four pieces can be clamped and machined at once, increasing production efficiency by four times compared to existing methods. Side machining on a horizontal machine tool is more conducive to chip removal, which is beneficial for drilling, milling, and thread machining. Attached Figure Description

[0014] The specific embodiments of this utility model will be described in further detail below with reference to the examples. These examples are used to illustrate this utility model, but are not intended to limit its scope.

[0015] See Figure 1 As shown, a bearing housing horizontal milling fixture for machining mating surfaces includes a base plate 1, positioning seats 2, an assembly plate 9, and a clamping assembly. The base plate 1 is a square plate with two U-shaped channels independently provided at the ends of its two opposite sides. The assembly plate 9 is a cross-shaped plate structure that is detachably installed through the middle of the surface of the base plate 1. Two positioning seats 2 are provided, symmetrically and adjacently installed at the two ends of the assembly plate 9, with one end aligned with the edge of the base plate 1. Two clamping assemblies are provided, each independently installed on the side of one positioning seat 2, for fixing the positioning seat 2 on the assembly plate 9.

[0016] Preferably, the assembly plate 9 has a certain width, and the width of the end plate of the cross is equal to the width of the bottom plate 1 and the side plate.

[0017] See Figure 2-3 As shown, the positioning seat 2 includes a pressure plate 6, bolts 7, screws 8, and a seat housing 10; the seat housing 10 is a hollow semi-cylindrical shell structure, with its bottom surface fixedly installed on the base plate 1 and a pressure plate 6 installed on its top; the pressure plate 6 is a plate structure with V-shaped ends; the screw 8 passes through the pressure plate 6, with its top fixedly installed on the upper end of the pressure plate 6 by bolts 7, and its bottom installed on the base plate 1.

[0018] See Figure 1 As shown, the clamping assembly includes a first side plate 3 and a second side plate 4; one end face of the first side plate 3 is fixedly installed on the outer side of the central shaft of the seat housing 10, and the other end face is connected to the second side plate 4; the second side plate 4 is fixedly installed on the base plate 1 by a second bolt 5.

[0019] Furthermore, it also includes multiple mounting holes, which are provided on the cross-section of the end face of the housing 10.

[0020] In this invention, a positioning plate is designed based on the positioning of a horizontal machine tool turntable, an inner circle positioning seat is designed based on the inner ring size of the bearing housing, and an outer V-shaped pressure plate is designed based on the outer arc.
