Problems solved by technology

[0003] In order to ensure the centering accuracy of the combined pin hole of the box body and the box cover, and to ensure the center distance, the traditional process of processing the pin hole is the drilling and reaming process, that is, the process is center drilling → drilling → reaming. The advantages of this processing method are: Good, high precision, the disadvantage is that the centering precision is low, if the box body and box cover are processed separately, the center distance cannot be guaranteed

Embodiment 1

[0013] Embodiment 1: as figure 1 As shown, the processing method of the gearbox includes the following steps:

[0014] a. Process the box cover: According to the drawing, strictly follow the size marked on the drawing, use a vertical machining center for processing, and center the drilling process at the four corners of the rectangular box cover 1 and the middle of the box cover 1 respectively. Then carry out the boring process, the four corners of the box cover 1 are processed to obtain the box cover pin hole 1a, the middle part of the box cover 1 is processed to obtain the box cover bearing hole 1b, when the boring process box cover bearing hole 1b, the whole box The cover bearing hole 1b is processed in two sections, one section is bored with a larger diameter, and the other section is bored with a small diameter, so that the case cover bearing hole 1b is a stepped hole;

[0015] b. Machining the box body: Use a three-coordinate measuring instrument to detect the center di...

Abstract

The invention discloses a processing method of a gear case, which comprises the following steps: a. processing a case cover; b. processing a case body; c. assembling, and fixing by pin bolts. The processing method of the gear case has the beneficial effects of: 1. respectively processing the case body and the case cover into finished products according to drawing requirements, and then assemblingthe case body and the case cover, thus being capable of guaranteeing the coaxiality and good interchangeability of two bearing holes, guaranteeing the quality, and simultaneously being applicable to be produced in batch without pairing or marking, and having low scrap rate; 2. adopting a novel technique for positioning, drilling and boring of a center drill, thus guaranteeing the center distance;and 3. leading the coaxiality of the assembled S1 and S2 to be 0.1 to 0.30, thus completely meeting the requirements of users.

Description

technical field [0001] The invention relates to the technical field of gear boxes, in particular to a processing method for a box cover of a gear box. Background technique [0002] Traditional gearbox processing includes box body 2 and box cover 1. The box cover 1 is mounted on the box body 2. The gear box is processed in this way: after the box body 2 and box cover 1 are combined and positioned, drilling is performed. Hinge the box body pin hole 2a and the box cover pin hole 1a, then install the positioning pins, and bore the box body bearing hole 2b and the box cover bearing hole 1b with the combined box body 2 and box cover 1, so as to ensure that the box cover 1 and The coaxiality of the bearing hole 1b of the upper box cover of the box body 2 and the bearing hole 2b of the box body, the advantage of this method is that the coaxiality of the combined processing is good, and the disadvantage is that the combined processing has higher requirements on the tool, such as the ...
