Description

Technical Field

[0001] This invention belongs to the field of machining technology, specifically relating to a machining method for shell parts, applicable to the machining of various shell parts. Background Technology

[0002] With the development of technology, the processing capabilities of equipment are becoming increasingly powerful, and the precision of parts processing is getting higher and higher. However, the processing of shell-type parts has always faced the problem of parts being easily deformed and difficult to process during the process. Traditional processing methods generally require repeated processing with small cutting tools to achieve the correct dimensions. This processing method is not only inefficient but also has a low pass rate. To improve processing efficiency, a simplified processing method for shell-type parts needs to be proposed. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a method for processing shell parts. The purpose of this invention is to avoid deformation of shell parts during processing, make the processing method simple and convenient, and improve processing efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A method for machining a housing part includes the following steps:

[0006] Step 1): Make a fixed shaft with a center hole according to the size and shape of the housing part; make a push rod according to the center hole of the fixed shaft; and make a locking cap with an opening according to the size of the housing part.

[0007] Step 2): Secure the housing parts between the end of the fixed shaft and the locking cap by connecting the locking cap and the fixed shaft;

[0008] Step 3): Insert the push rod into the center hole of the fixed shaft to press against the inner wall of the housing part, and then fix the push rod and the fixed shaft together.

[0009] Step 4): Fix the fixed shaft on the machine tool to complete the machining of the housing parts;

[0010] Step 5): After processing, loosen the top rod and locking cap, and remove the housing part from the fixed shaft.

[0011] Further defining the above solution, the side wall of the fixed shaft is provided with screw fixing holes and U-shaped grooves, and the side wall of the push rod is provided with threaded holes and U-shaped fixing grooves; the push rod is installed into the center hole of the fixed shaft, and the moving handle is fixedly connected to the threaded hole on the push rod through the U-shaped groove on the fixed shaft. The forward and backward position of the push rod is adjusted by the moving handle; the screw is screwed into the screw fixing hole of the fixed shaft, and the lower end of the screw is adapted to the U-shaped fixing groove of the push rod. After the push rod is adjusted, it is fixed by tightening the screw.

[0012] Further specifying the above solution, the locking cap, fixed shaft, top rod, and moving handle are all made of aluminum alloy.

[0013] As a further limitation of the above scheme, the front end of the fixed shaft is provided with a positioning protrusion ring, which is used to adapt to the inner cavity shape of the housing part for clamping and positioning.

[0014] As a further limitation of the above scheme, the outer surface of the front end of the fixed shaft is provided with an external thread for engaging and fixing with the locking cap.

[0015] Advantages of this invention compared to existing technologies:

[0016] 1. This solution addresses the problem of easy deformation and low processing efficiency of shell-type parts during machining. The method involves connecting a push rod with a U-shaped fixing groove to a fixed shaft via screws. The fixed shaft is connected to the machine tool spindle via a chuck. The thin-walled part to be machined is first placed against the positioning convex ring of the fixed shaft, and then secured to the fixed shaft with a locking cap. The position of the push rod is adjusted by moving the handle on the push rod, ensuring the end face of the push rod fits against the inner wall of the part. Finally, the push rod and fixed shaft are fixed together with screws. This method avoids deformation of the part during machining. The machining method is simple in structure, easy to manufacture, and can greatly improve the machining efficiency of shell-type parts.

[0017] 2. This processing method has a wide range of applications and strong versatility. It is suitable for processing shell-type parts of various shapes and sizes. This processing method is easy to use, simple to disassemble, and has low manufacturing costs. Attached Figure Description

See reference. Figure 7 As shown, the top rod 6 has a threaded hole 6-1 and a U-shaped fixing groove 6-2 on its side wall.

[0030] Step 2): The positioning protrusion 3-4 on the fixed shaft 3 is adapted to the inner cavity shape of the housing part 2 for clamping and positioning. Then, the housing part 2 is fixed between the end of the fixed shaft 3 and the locking cap 1 by connecting the locking cap 1 and the fixed shaft 3.

[0031] Step 3): Insert the push rod 6 into the center hole 3-1 of the fixed shaft 3 to press against the inner wall of the housing part 2, and then fix the push rod 6 and the fixed shaft 3 so that a part of the housing part 2 protrudes from the opening in the center of the locking cap 1.

[0032] For specific instructions, please refer to [link / reference]. Figure 1-3As shown, the push rod 6 is inserted into the center hole 3-1 of the fixed shaft 3. The movable handle 4 is fixed to the threaded hole 6-1 on the push rod 6 through the U-shaped groove 3-3 on the fixed shaft 3. The screw 5 is screwed into the screw fixing hole 3-2 of the fixed shaft 3, and the lower end of the screw 5 is adapted to the U-shaped fixing groove 6-2 of the push rod 6. The push rod 6 is moved and adjusted back and forth by the movable handle 4 to ensure that the end face of the push rod 6 is in contact with the inner wall of the housing part 2. After the push rod 6 is adjusted, it is fixed by tightening it with the screw 5.

[0033] Step 4): Fix the fixed shaft 3 onto the machine tool chuck, and the machine tool completes the machining of the housing part 2;
