Abstract
In order to solve the problems of high cost and low production efficiency of a method for machining a guide groove on a produced shaft sleeve by adopting an electric pulse process in the prior art, the invention provides a method for machining the shaft sleeve with the guide groove, which comprises the following steps: step 1, pressing raw material powder into a shaft sleeve primary blank by adopting a mould, wherein the mould is provided with a bulge matched with a key groove to be processed, and an inner hole of the obtained shaft sleeve primary blank is provided with a key groove with a corresponding position; step 2, grinding an inner hole and an outer circle of the blank after the blank is fired; and 3, machining a guide groove communicated with the key groove. The shaft sleeve key groove and the guide groove are produced by adopting the mode, the previous deep processing electric pulse process is reduced, the key size control requirement provided by the process machining is met by the method, the machining efficiency is high, and the method is particularly suitable for batch machining.
Description
Technical Field
The invention belongs to the field of machining, and relates to a machining method of a shaft sleeve with a guide groove.
Background
In order to meet the use requirement, the hard alloy shaft sleeve with the inner hole key groove needs to be processed. Taking a hard alloy shaft sleeve widely applied to operations such as treatment of an oil-submerged pump and the like as an example, a guide groove which is consistent with the extension direction of an inner hole is arranged in the shaft sleeve, the size of the guide groove is matched with a key on a workpiece, when the hard alloy shaft sleeve is used, the key on the workpiece slides along the guide groove in the shaft sleeve, the workpiece cannot rotate circumferentially relative to the shaft sleeve through the matching of the key and the guide groove, the sharp edge defect during assembly and operation is reduced for the convenience of assembling the key and the shaft sleeve guide groove, openings which are slightly larger than those of the key groove of the guide groove are required to be arranged at two ends of the guide groove, the guide groove and the key groove of the hard alloy shaft sleeve, particularly the guide groove and the key groove with high precision requirements, the produced shaft sleeve is usually required to be processed by adopting an electric pulse process, the cost of an electric processing mode is extremely high, the cost, and it is difficult to meet the delivery date requirements of users for mass production.
Disclosure of Invention
Based on the above problems, the invention aims to provide a method for quickly producing a shaft sleeve product with a guide groove, which improves the processing efficiency, is particularly suitable for batch processing, can ensure the processing precision and is simple.
In order to achieve the purpose, the invention adopts the technical scheme that: a processing method of a shaft sleeve with a guide groove comprises the following steps:
and 3, machining a guide groove communicated with the key groove.
According to the processing method of the shaft sleeve with the guide groove, provided by the invention, as the precision requirement of the key groove is lower, the raw material powder is pressed into the shaft sleeve primary blank with the key groove by adopting the die, then the guide groove is precisely processed, the processing of the guide groove can be realized by adopting a wire cutting method, so that the shaft sleeve does not need to be processed firstly, and then the guide groove and the key groove are processed by an electric pulse process, and the processing cost can be reduced by more than 40%.
The raw material powder adopted in the step 1 is hard alloy powder.
Furthermore, the method provided by the invention is suitable for processing the shaft sleeve with small size and high precision requirement, and the size of the inner hole of the shaft sleeve to be processed is less than 32 mm; the depth of the guide groove to be processed is less than 1.1mm, and the width of the guide groove to be processed is less than 1.7 mm; the key groove to be processed is conical.
The invention has the beneficial effects that: the method has higher processing efficiency, is particularly suitable for batch processing, can ensure the processing precision and has simple processing method.
Drawings
Fig. 1 and 2 are schematic diagrams of a shaft sleeve blank with a key groove processed in step 1;
FIG. 3 is a schematic view of a finished sleeve after machining;
wherein, 1 is a key groove, and 2 is a guide groove.
Detailed Description
The invention is further described with reference to the following figures and examples:
examples
In this embodiment, a detailed explanation is given to a method for producing a guide groove of a hard alloy shaft sleeve by taking the production of the guide groove of the hard alloy shaft sleeve as an example.
The requirements of the shaft sleeve to be processed in the embodiment are as follows: the inner hole is 30.2+ (0-0.5) mm, the groove depth of the guide groove 2 is 0.8+ (0-0.356) mm, the width of the key groove 1 is 1.626+ (0-0.025) mm, and the groove shape is 2.55 + -0.32 mmx5.08 + -1.27 mm.
The processing method adopted in the embodiment guarantees the shape of the guide groove 2 for blank forming, and the processing method of the shaft sleeve with the guide groove 2 is characterized by comprising the following steps of:
and 3, machining a guide groove 2 communicated with the key groove 1 by wire cutting, as shown in fig. 3.
The guide groove 2 at the position of the key groove 1 of the hard alloy shaft sleeve is produced by adopting the measuring mode, the traditional deep processing electric pulse process is reduced, and the key size control requirement provided by the process machining is met by the method.
Although the present embodiment describes the method for measuring the production of the guide groove of the sleeve by taking the example of machining a cemented carbide sleeve product, the method for machining the guide groove of the sleeve is not limited to machining a cemented carbide sleeve, and may be applied to machining guide grooves made of other materials.
