Description

Technical Field

[0001] The invention relates to the technical field of motor shell processing, and in particular to a friction welding device for motor shell pretreatment and an automatic feeding method thereof. Background Art

[0002] The main reason for setting cooling fins on the outer wall of the motor casing is to improve the heat dissipation efficiency. The cooling fins increase the surface area and enhance heat exchange, so that the motor can effectively reduce the temperature and prevent overheating when running at high load. The cooling fins fixed on the outer wall of the motor casing are welded instead of cast in one piece. This is mainly because welding can use different materials to optimize the heat dissipation performance, while one-piece casting may limit the material selection and make it difficult to achieve the best heat dissipation effect and manufacturing flexibility. Through this design, the operating stability and service life of the motor are improved.

[0003] The prior art lacks continuous welding automation equipment for welding multiple cooling fins to the outer wall of the motor casing. When welding multiple cooling fins to the outer wall of the motor casing, workers need to use clamps to fix the cooling fins to the outer wall of the motor casing. After waiting for the welding to be completed, the clamps need to be loosened and moved to a position that does not hinder the rotation of the motor casing, and the cooling fins welded to the outer wall of the motor casing are turned away, and the above steps are repeated again. During this process, workers need to move the clamps frequently, resulting in an extension of the production cycle. Secondly, manual operation is prone to introduce errors, which may affect the welding quality and position accuracy of the cooling fins. Repeated operations increase the labor intensity and fatigue of workers, which may lead to safety hazards. Finally, the lack of automation will limit the expansion of production scale. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that there is a lack of continuous welding automation equipment for welding multiple cooling fins to the outer wall of the motor casing in the prior art. When welding multiple cooling fins to the outer wall of the motor casing, workers are required to use clamps to fix the cooling fins to the outer wall of the motor casing.

During this process, workers need to move the clamps frequently, resulting in an extension of the production cycle. Secondly, manual operation is prone to introduce errors, which may affect the welding quality and position accuracy of the cooling fins.

A micro switch (5) is fixedly arranged on the vertical plate (7) obliquely below the trigger block (33), and the micro switch (5) is connected to the control circuit of the release cylinder (13).

6. The friction welding equipment for motor housing pretreatment according to claim 5 is characterized in that: A top column (24) is fixedly provided at the top edge of the horizontal rod (22); a narrow vertical slot (73) is provided on the vertical plate (7) at the top of the wide vertical slot (71); the top column (24) extends into the narrow vertical slot (73); an outer wall of the top column (24) is fixedly connected to one end of an auxiliary spring (23); and the other end of the auxiliary spring (23) is fixedly connected to the top of the narrow vertical slot (73).

7. The friction welding equipment for motor housing pretreatment according to claim 5, characterized in that: A transverse block (31) is screwed into the outer wall of the transverse screw rod (251) through a thread. The transverse block (31) has the same width as the inner cavity of the transverse guide frame (20). A stirring motor (30) is fixedly disposed on the top surface of the transverse block (31). A stirring head (32) is fixedly disposed at the output end of the stirring motor (30).

8. An automatic feeding method for a friction welding device for motor housing pretreatment, used for a friction welding device for motor housing pretreatment according to any one of claims 1 to 7, characterized in that: The steps include: S1, preparation for loading the heat sink fins and fixing the motor housing (4): the worker places a plurality of heat sink fins into the storage slope (18). In the initial state, the common cylinder (6) extends, and the continuous release assembly closes the release port (16) at the bottom of the storage slope (18). The common cylinder (6) controls the pressing assembly and the stirring welding assembly to be in the avoidance position through the common lifting assembly, and sets the three-jaw chuck (1) and controls the three-jaw chuck (1) to fix the motor housing (4). S2, the heat sink fin reaches the welding position and the heat sink fin is fixed: the main controller (201) is started, the main controller (201) controls the common cylinder (6) to retract, and the pressing component and the stirring welding component are manipulated to lean against the outer wall of the motor housing (4). During this process, the connection release component opens the release port (16) at the bottom of the material storage slope (18), and a single heat sink fin falls into the guide frame (8). The pressing component fixes the heat sink fin, the stirring welding component moves to the welding position, and the main controller (201) controls the stirring welding component to stir and weld the contact between the heat sink fin and the motor housing (4); S3, the next heat sink fin enters the welding position and the new heat sink fin is fixed: the main controller (201) controls the common cylinder (6) to extend, and the continuous release assembly closes the release port (16) at the bottom of the material storage slope (18). The common cylinder (6) controls the holding assembly and the stirring welding assembly to be in the avoidance position through the common lifting assembly. The three-jaw chuck (1) drives the welded heat sink fin to turn away from the holding assembly and one side of the stirring welding assembly. Finally, the main controller (201) loops the S2 step until the entire device welds all the heat sink fins to the outer wall of the motor housing.
