Description

Technical Field

[0001] The invention relates to the technical field of workpiece cutting devices, and in particular to a slitting and cutting device for processing axle sleeves. Background Art

[0002] The axle (also called the axle) is connected to the frame (or load-bearing body) through the suspension, and wheels are installed at both ends. The function of the axle is to bear the load of the car and maintain the normal driving of the car on the road.

[0003] According to the different functions of the wheels on the axle, the axle is divided into four types: steering axle, drive axle, steering drive axle and supporting axle. Among them, the front axle of most cars uses a steering drive axle, which has both steering and driving functions, so it is the most widely used.

[0004] A complete axle is usually assembled from several parts, including a sleeve part, which is mounted on the axle to serve as a connection and support. Its mass production method in the workshop is mainly: a long tube is fixed and then cut into individual, small sections of axle sleeves.

[0005] In the existing workshop production, in the process of preparing small-segment axle sleeves from long tube raw materials, the processing method usually adopted is: fix the two ends of the long tube raw materials with a fixing device, and then cut them into sections with equipment such as a grinding wheel cutter to obtain a single axle sleeve. This processing method mainly has the following problems:

[0006] 1. Although the fixing method of clamping at both ends greatly increases the clamping stability of the long tube workpiece during the cutting process, the cutting and segmenting of a long tube workpiece is not simply to divide it into two from the middle, but requires multiple cuttings to divide it into multiple equal-length axle sleeves. After each cutting, the remaining long tube workpiece will have new ends. If the clamping method of fixing at both ends is adopted, the two ends of the long tube workpiece need to be clamped and fixed again after each cutting, and the length of the long tube workpiece when clamped and fixed again is different from before, and the clamping reference also needs to be adjusted accordingly. In addition, since the position of the cutting tool is relatively fixed, the clamping position of the long tube workpiece also needs to be adjusted after one cutting to ensure the uniform cutting length. The above process needs to be repeated after each cutting, and the operation is cumbersome. Therefore, the method of clamping and cutting at both ends is very unreasonable.

[0007] 2. During the workpiece cutting process, the contact area between the cutting tool and the workpiece will inevitably be affected by the cutting force. During the cutting process of the tool, the cutting part of the workpiece will be deformed due to the cutting force. This deformation is particularly obvious when cutting long tube workpieces with thin outer walls. This requires secondary shaping of the cut axle sleeve after cutting, which adds unnecessary processing.

[0008] 3. In the process of manufacturing axle bushings using existing processing methods, multiple processes including loading, feeding, cutting, and unloading require a lot of manual participation, the degree of automation is low, and the processing process is difficult to achieve continuity, resulting in low overall processing efficiency.

[0009] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0010] In view of the defects in the prior art, the present invention provides a slitting and cutting device for processing axle bushings, which is used to solve the problems in the traditional technology of preparing axle bushings by slitting long tube workpieces, such as inconvenient processing by clamping at both ends, easy deformation of the cut parts after being subjected to force affecting product quality, and insufficient automation and continuity of processing.

In the slitting and cutting process, the workpiece clamping assembly and the rotating positioning assembly are actually still clamping the two ends of the long tube workpiece.

Under this supporting mode, the port of the axle sleeve obtained by cutting will not undergo plastic deformation, and the product does not need to be subjected to secondary processing and shaping after cutting, thereby reducing unnecessary processing processes, shortening processing time, and improving processing efficiency.
