Description

Technical Field

[0001] This utility model relates to the field of iron core processing technology, and more specifically, to a concentric tooling for inserting iron cores into a frame. Background Technology

[0002] The hot-fitting process for the iron core includes: heating the housing, positioning the iron core, pressing the iron core in three stages, and maintaining pressure.

[0003] The heat-fitting process between the motor core and the housing is a crucial step in the servo stator manufacturing process, directly impacting the performance and reliability of the servo motor during operation. During this process, the small gap between the core and housing makes it prone to aluminum shavings from scraping, resulting in eccentricity, abnormal noise, and performance issues. Failure to address this promptly can lead to a large number of defective products and significant waste of raw materials. In practice, the operator places the core on a positioning fixture, heats and expands the housing, places it on top of the core, and then starts the machine to press the core in. However, this pressing process can easily cause the housing to tilt.

[0004] In actual operation, the following problems may occur: when the casing is heated and placed in, there is a safety hazard due to the high temperature; manual positioning may result in a tilt angle; when pressing down, the casing may scrape against the wall due to its tilt. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a concentric tooling for iron core insertion into the frame. It can achieve concentricity of the upper and lower parts of the iron core housing, quickly position the iron core during insertion into the frame to reduce safety hazards, improve the work efficiency of technicians, and also improve the yield rate of products.

[0006] To solve the above problems, this utility model adopts the following technical solution: a concentric fixture for core insertion, including a main support frame, a worktable at the upper end of the main support frame, a secondary support frame fixedly connected to the upper end of the worktable, a drive box fixedly connected to the upper end of the secondary support frame, a cylinder installed in the drive box, and a frame pressing fixture fixedly installed at the upper end of the worktable, the frame pressing fixture being located at the bottom side of the drive box. This can achieve concentricity of the core housing, quickly position the core during insertion, reduce safety hazards, improve the work efficiency of technicians, and increase the yield rate of products.

[0007] Furthermore, the pressing frame fixture includes a base plate fixedly connected to the worktable. Four evenly distributed slide rails are fixedly connected to the upper end of the base plate. A forming plate and an upper pressing plate are slidably connected to the outer end of the slide rails. The base plate, forming plate, and upper pressing plate are distributed from bottom to top. A punch head is embedded in the upper end of the upper pressing plate. The punch head is connected to the power output end of a cylinder. An iron core frame is fixedly installed on the upper end of the forming plate. By activating the cylinder, its power output end can be extended, thereby driving the punch head and the upper pressing plate to move downward along the slide rails until the upper pressing plate contacts the forming plate. This causes the bottom end of the punch head to exert pressure on the iron core frame, causing the iron core on the iron core frame to be inserted into the iron core frame, thereby realizing the iron core insertion into the frame.

[0008] Furthermore, two symmetrical first limiting rods are fixedly connected to the upper end of the base plate. The first limiting rods pass through the forming plate and the upper pressure plate. Two symmetrical first springs are fixedly connected between the base plate and the forming plate. The first springs are located outside the first limiting rods. Two symmetrical second limiting rods are fixedly connected to the upper end of the forming plate. The second limiting rods pass through the upper pressure plate. Two symmetrical second springs are fixedly connected to the upper end of the forming plate. The second springs are located outside the second limiting rods. By setting the second springs and the first springs, the possibility of damage to the base plate, forming plate and upper pressure plate due to excessive pressure can be reduced during the stamping process through their buffering effect, thereby improving the service life of the equipment.

[0009] Furthermore, the outer end of the main support frame is fixedly connected to two mutually symmetrical first connecting plates, and the outer end of the workbench is fixedly connected to two mutually symmetrical second connecting plates. The first connecting plates and the second connecting plates are fixedly connected by screws. By setting the first connecting plates and the second connecting plates, the main support frame and the workbench can be easily disassembled and installed, thereby facilitating the transportation of the equipment.

[0010] Furthermore, four evenly distributed support columns are fixedly connected to the upper end of the workbench. The support columns are located inside the secondary support frame. By setting the support columns, the stability of the entire device can be improved, thereby making the device safer in operation.

[0011] Furthermore, a support seat is fixedly connected to the upper end of the base plate, and a contact cylinder is fixedly connected to the upper end of the support seat. By setting the support seat and the contact cylinder, the downward-moving forming plate can be supported, thereby improving the efficiency of the iron core entering the frame.

[0012] Compared with the prior art, the advantages of this utility model are: (1) This solution can achieve concentricity of the iron core housing, and the iron core can be quickly positioned when entering the frame to reduce safety hazards, improve the work efficiency of technicians, and also improve the yield rate of products.

[0013] (2) By starting the cylinder, its power output end can be extended, thereby driving the punch head and the upper pressure plate to move down along the slide rail until the upper pressure plate contacts the forming plate, causing the bottom end of the punch head to exert pressure on the iron core frame, causing the iron core on the iron core frame to be inserted into the iron core frame, thereby realizing the iron core entering the frame.

[0014] (3) By setting the second spring and the first spring, the base plate, forming plate and upper pressure plate can be reduced due to excessive pressure during the stamping operation, thereby improving the service life of the equipment.

[0015] (4) Two symmetrical first connecting plates are fixedly connected to the outer end of the main support frame, and two symmetrical second connecting plates are fixedly connected to the outer end of the worktable. The first connecting plates and the second connecting plates are fixedly connected by screws. By setting the first connecting plates and the second connecting plates, the main support frame and the worktable can be easily disassembled and installed, which facilitates the transportation of the equipment.

[0016] (5) Four evenly distributed support columns are fixedly connected to the upper end of the workbench. The support columns are located inside the secondary support frame. By setting the support columns, the stability of the entire equipment can be improved, thereby making the equipment safer in operation.

[0017] (6) A support seat is fixedly connected to the upper end of the base plate, and a contact cylinder is fixedly connected to the upper end of the support seat. By setting the support seat and the contact cylinder, the downward-moving forming plate can be supported, thereby improving the efficiency of the iron core entering the frame.
