Description

Technical Field

[0001] The utility model relates to the technical field of processing fixtures, in particular to a fixture for a reducer box body. Background Art

[0002] The reducer box body is a basic component for installing each transmission shaft; when the reducer is working, relatively large reaction forces are generated when each shaft transmits torque, and act on the box body. There are various structural forms of the reducer box body. During small-batch manufacturing, boring needs to be performed on the reducer box body. During the boring process of the reducer box body, the reducer box body needs to be fixed. However, most of the existing fixtures for fixing the reducer box body clamp the side of the reducer box body through clamping plates to achieve the purpose of fixation. For some reducer box bodies, the side steps protrude short, resulting in unreliable clamping. There are problems such as offset and damage to the outer peripheral wall of the reducer box body when the reducer box body is clamped. Due to unreliable clamping, the reducer box body shakes during boring, resulting in an elliptical output shaft hole after boring, and the processing accuracy and quality of the reducer box body are low.

[0003] For example, Chinese Patent Publication No. CN214818033U, publication date November 23, 2021, titled "A fixture for processing a reducer box body", includes a support mechanism and a clamping plate mechanism fixedly welded on the support mechanism. By fixedly installing the clamping plate on the slider adjusting member and fixedly setting the slider adjusting member at one end of the support bottom plate, when fixing the reducer box body, the reducer box body is placed horizontally on the support bottom plate, the box opening of the reducer box body faces the clamping plate, and then the clamping plate is extended into the reducer box body and pressed down to clamp and fix the box body, which is convenient for processing the inside of the reducer box body; by movably sleeving two groups of reinforcing blocks on the guide post rod, threadedly installing fastening bolts on the side of the reinforcing blocks, and fixedly installing the clamping plate on the reinforcing blocks, when the clamping plate is extended into the box body, the distance between the two groups of reinforcing blocks can be adjusted according to the width of the box body, so that the clamping plate can press and clamp reducer box bodies with different widths for fixation.

[0004] The disadvantages of the existing patent are as follows: The existing fixture for the reducer box body clamps the side of the reducer box body through a clamping plate. Since the side steps of some reducer box bodies protrude short and are not firmly clamped by the clamping plate, problems such as offset and shaking occur during the boring process of the reducer box body, resulting in low processing accuracy and quality of the reducer box body. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the problem that the existing fixture for the reducer box body cannot clamp the reducer box body with short protruding side steps, resulting in low subsequent machining accuracy and quality of the reducer box body, and to provide a fixture for the reducer box body that is firmly fixed to improve the machining accuracy and quality of the reducer box body.

[0006] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

The fixture includes a fixing plate for supporting the reducer box body, and cushion blocks and bolts are provided at the four corners of the fixing plate. The bolts sequentially pass through the fixing plate and the cushion blocks and are threadedly connected with the screw holes. Sleeve pins are sleeved on any two diagonally distributed bolts. The upper end of the sleeve pin is inserted into the first counterbore, and the lower end passes through the cushion block and is inserted into the fixing plate. The fixture for the reducer box body described in this solution is used to fix the reducer box body, so that the reducer box body will not shift or shake during subsequent boring, and the machining accuracy and quality of the reducer box body are improved.

[0008] Working principle: Cushion blocks are respectively placed at the four corners of the fixing plate, and two sleeve pins are inserted into the cushion blocks and the fixing plate. The two sleeve pins are diagonally distributed. The upper end of the inserted pin is higher than the upper end surface of the cushion block, and the lower end passes through the cushion block and is inserted into the fixing plate. The bottom surface of the reducer box body to be bored after the bottom surface is processed is attached to the upper surfaces of the four cushion blocks, and two diagonally distributed sleeve pins are inserted into the first counterbores of the reducer box body for positioning. Then, the screw part of the bolt sequentially passes through the fixing plate and the cushion block and is threadedly connected with the screw hole. The bolt is tightened to firmly fix the reducer box body on the fixing plate, so that the reducer box body will not shift or shake during subsequent boring, and the machining accuracy and quality of the reducer box body are improved.

[0009] This technical solution uses one plane and two pins to achieve the positioning of the reducer box body. This structure has accurate, convenient and stable positioning. Only two sleeve pins need to be set, which saves processing steps and equipment costs while ensuring accurate positioning.

[0010] This technical solution uses bolts to replace the pressing plates in the prior art, solves the problem that the existing fixture for the reducer box body cannot clamp the reducer box body with short protruding side steps, resulting in low subsequent machining accuracy and quality of the reducer box body, and avoids problems such as offset and shaking of the reducer box body during the boring process, and avoids the problem of low machining accuracy and quality of the reducer box body.

Secondly, it is convenient to make the upper end faces of the cushion blocks flush. Compared with making the upper end face of the fixed plate flush, it is more convenient to make the cushion blocks flush. Moreover, the cushion blocks are provided with a shock-absorbing function.

[0018] Preferably, a shock-absorbing sleeve is sleeved on the pin sleeve. The upper end of the shock-absorbing sleeve is flush with the upper end of the cushion block, and the lower end passes through the cushion block and is inserted into the fixing plate. The shock-absorbing sleeve is sleeved on the outer peripheral wall of the pin sleeve. The pin sleeve together with the shock-absorbing sleeve passes through the cushion block and is inserted into the fixing plate, which on the one hand achieves a shock-absorbing effect on the reducer housing in the horizontal direction, and on the other hand prevents wear between the pin sleeve and the cushion block and the fixing plate due to shaking during subsequent boring of the reducer housing.

[0032] In order to make the objectives, technical solutions and advantages of the embodiments of the technical solutions of the utility model clearer, the following further describes the utility model in conjunction with the drawings and specific embodiments.

The fixture includes a fixing plate 2 for supporting the reducer housing 1. Pad blocks 3 and bolts 4 are provided at the four corners of the fixing plate 2. The bolts 4 sequentially pass through the fixing plate 2 and the pad blocks 3 and are threadedly connected to the screw holes 1.1. Sleeve pins 5 are sleeved on any two diagonally distributed bolts 4. The upper ends of the sleeve pins 5 are inserted into the first counterbores 1.2, and the lower ends pass through the pad blocks 3 and are inserted into the fixing plate 2.

[0034] The reducer housing 1 is a basic component for installing each transmission shaft. Since relatively large reaction forces are generated when each shaft transmits torque during the operation of the reducer and act on the housing. There are various structural forms of the reducer housing 1. During small-batch manufacturing, it is necessary to bore the reducer housing 1. During the boring process of the reducer housing 1, the reducer housing 1 needs to be fixed. However, most of the existing fixtures for fixing the reducer housing 1 clamp the side of the reducer housing 1 through clamping plates to achieve the purpose of fixation. For some reducer housings 1 with short protruding side steps, there is a problem of unreliable clamping. When the reducer housing 1 is clamped, there are problems of offset and damage to the outer peripheral wall of the reducer housing 1. Due to unreliable clamping, the reducer housing 1 shakes during boring, resulting in an elliptical output shaft hole after boring, and causing problems of low machining accuracy and quality of the reducer housing 1.

[0035] To solve the problem that the existing fixture for the reducer housing 1 cannot clamp the reducer housing 1 with short protruding side steps, resulting in low machining accuracy and quality of the subsequent processing of the reducer housing 1, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 shown, a fixture for a reducer housing is provided, which is firmly fixed to improve the machining accuracy and quality of the reducer housing 1.
