Description

Technical Field

[0001] This utility model relates to the field of motor parts manufacturing technology, specifically to a laser deburring device for motor laminations. Background Technology

[0002] Motor laminations are thin metal sheets stamped from silicon steel sheets, used in the stator or rotor of motors. They are core components affecting motor efficiency. Due to long-term wear of the cutting edges of the stamping dies, the material separation effect is impaired, leading to tearing and irregular cross-sections with large burrs. This is especially true when the punch and die edges become blunt during the stamping process. These burrs cause the stator core teeth to spring open beyond permissible limits, resulting in a lower power factor, increased copper losses, and higher temperature rise. Furthermore, burrs increase the risk of short circuits between stator core laminations, leading to increased eddy current losses and further affecting the motor's heat conduction and temperature rise. The presence of burrs also makes assembly difficult, increasing assembly time and costs. Additionally, burrs generate extra friction and wear during motor operation, shortening the motor's lifespan. Therefore, it is necessary to remove burrs from motor laminations.

[0003] Currently, there are two methods for removing burrs from motor laminations: manual removal and machine removal. However, manual deburring is inefficient, labor-intensive, and the quality cannot be guaranteed. Machine removal, on the other hand, mostly uses contact grinding, which is dusty and environmentally unfriendly, and cannot be applied to motor laminations of various shapes and sizes. Therefore, it is necessary to design a laser deburring device for motor laminations to solve the problems mentioned in the background. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Example:

[0021] This utility model provides a laser deburring device for motor laminations. The laser deburring device for motor laminations adopts a non-contact laser deburring processing method, which is highly accurate, efficient and convenient, and ensures quality. It is dust-free and environmentally friendly, and is applicable to motor laminations of various shapes and specifications, thereby solving the problems mentioned in the background art.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] A laser deburring device for motor laminations includes a base 1 for laser deburring of motor laminations. A worktable 2 is fixedly mounted on the top surface of the base 1. A motor lamination clamping and flipping mechanism 3 is provided on the top surface of the worktable 2. A laser generator 5 for deburring is movably mounted on the top of the base 1 near the top surface of the motor lamination clamping and flipping mechanism 3 via an automatic lifting and displacement mechanism 4.

[0024] The motor lamination clamping and flipping mechanism 3 is composed of a flipping component 31 and a clamping component 32. The automatic lifting and displacement mechanism 4 includes a fixed base 41 fixedly installed on the top surface of the base 1, a fixed top seat 42 provided on the top of the fixed base 41, a servo motor 421 fixedly installed on the top surface of the fixed top seat 42, and an automatic lifting platform 45 movably installed between the fixed base 41 and the fixed top seat 42 through a transmission screw 43 and a limit slide rod 44. The output shaft of the servo motor 421 and the transmission screw 43 are fixedly connected by a coupling. An automatic lifting platform 45 is movably mounted with a longitudinal displacement platform 47 on the side near the worktable 2 via a first displacement electric telescopic cylinder 46. A transverse displacement platform 49 is movably mounted with the end of the longitudinal displacement platform 47 near the worktable 43 via a second displacement electric telescopic cylinder 48. The transverse displacement platform 49 is fixedly connected to the deburring laser generator 5. First, the clamping assembly 32 clamps and fixes the motor laminations on the top of the worktable 2. Then, the servo motor 421 operates, causing the automatic lifting platform 45 to move downwards, simultaneously deburring the laminations. The laser generator 5 for deburring moves downwards until it reaches a suitable working height. Simultaneously, the laser generator 5 uses a high-energy laser beam to irradiate the surface of the workpiece, causing it to be locally heated to vaporize and evaporate, thereby achieving precise deburring. The first displacement electric telescopic cylinder 46 and the second displacement electric telescopic cylinder 48 respectively drive the longitudinal displacement stage 47 and the transverse displacement stage 49 to move, thereby driving the laser generator 5 to achieve longitudinal and transverse displacement, so as to remove burrs at different positions on the motor stamping with laser. After deburring one side is completed, the automatic lifting stage 45 automatically resets and rises to a certain height. The flipping component 31 flips the clamping component 32 180 degrees to flip the motor stamping. Then, the above operation is repeated to achieve laser deburring on the other side of the motor stamping. The entire process adopts a non-contact laser deburring method, which is highly accurate, efficient and convenient, with guaranteed quality, no dust and environmentally friendly. It is also suitable for motor stampings of various shapes and specifications. At the same time, it can realize automatic double-sided deburring, which is highly practical.

[0025] Furthermore, in this embodiment, please refer to Figure 1 Several sets of support blocks 21 are fixedly installed on the top surface of the workbench 2 near the center, which can support the motor laminations and make a certain height difference between the motor laminations and the workbench 2, so that the clamping assembly 32 can effectively clamp the motor laminations.

[0026] Furthermore, in this embodiment, please refer to Figure 3 The flipping assembly 31 includes two sets of fixed bases 311 fixedly installed on the top surface of the base 1. A U-shaped frame 313 is movably installed between the two sets of fixed bases 311 via a first rotary motor 312. A clamping assembly 32 is movably installed inside the U-shaped frame 313 via a second rotary motor 314. Under the action of the first rotary motor 312, the U-shaped frame 313 automatically rotates 90 degrees, so that the flipping of the clamping assembly 32 can be smoothly unfolded. At the same time, under the action of the second rotary motor 314, the clamping assembly 32 automatically rotates 180 degrees to automatically flip the motor lamination.

[0027] Furthermore, in this embodiment, please refer to Figure 4 The clamping assembly 32 includes a retractable frame 321. At both ends of the retractable frame 321, a first arc-shaped motor lamination clamp 323 and a second arc-shaped motor lamination clamp 324 are respectively movably mounted via electric telescopic cylinders 322. The first arc-shaped motor lamination clamp 323 and the second arc-shaped motor lamination clamp 324 are symmetrically distributed. Anti-slip washers 325 are fixedly installed on the inner walls of the first arc-shaped motor lamination clamp 323 and the second arc-shaped motor lamination clamp 324. The electric telescopic cylinder 322 extends into the retractable frame 321. Under its action, the first arc-shaped motor lamination clamp 323 and the second arc-shaped motor lamination clamp 324 move closer to the motor lamination until they are clamped. The design of the anti-slip washers 325 can effectively prevent the motor lamination from slipping during the clamping process, making it more stable and reliable.

[0028] In this embodiment, the specific implementation scenario is as follows: First, the motor lamination to be processed is placed on several sets of support blocks 21 on the top surface of the worktable 2. Then, the electric telescopic cylinder 322 for clamping expands into the return frame 321. Under its action, the first arc-shaped motor lamination clamp 323 and the second arc-shaped motor lamination clamp 324 move closer to the motor lamination until they are clamped. Then, the servo motor 421 works, and under its action, the automatic lifting platform 45 moves downward. At the same time, the deburring laser generator 5 moves downward until it reaches a suitable working height. Simultaneously, the deburring laser generator 5 uses a high-energy laser beam to irradiate the surface of the workpiece, causing it to be locally heated to vaporize and evaporate, thereby achieving the effect of precise deburring. The first displacement electric telescopic cylinder 46 and the second displacement electric telescopic cylinder 48 respectively drive the longitudinal displacement stage 47 and the transverse displacement stage 49 to move, thereby driving the deburring laser generator 5 to achieve longitudinal and transverse displacement, so as to remove burrs at different positions on the motor lamination with laser. After deburring one side is completed, the automatic lifting stage 45 automatically resets and rises to a certain height, and flips the clamping stage 32 by 180 degrees through the flipping component 31 to flip the motor lamination. Then the above operation is repeated to achieve laser deburring of the other side of the motor lamination. The whole process adopts a non-contact laser deburring method, which is highly accurate, efficient and convenient, with guaranteed quality, no dust and environmentally friendly. It is also suitable for motor laminations of various shapes and specifications.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
