Description

Technical Field

[0001] This utility model relates to the field of motor rotor production technology, specifically to an automated spot welding machine for motor rotor production. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines. Currently, the most common method is to use heat energy, water energy, etc., to drive a generator rotor to generate electricity. The rotating part of the motor is called the rotor, and the stationary part is called the stator. The rotor of an electric motor has many weld points. If manual welding is used, it is time-consuming and labor-intensive, and the welding effect is not good. Therefore, machine welding is generally used.

[0003] Existing automated spot welding machines for motor rotor production do not have automatic closing protective components during automatic welding. Before welding, workers need to manually close the door, and after welding, workers need to manually open the door, which is very troublesome. Utility Model Content

[0004] The purpose of this utility model is to provide an automated spot welding machine for motor rotor production. The motor rotor production technology disclosed in this utility model has a longitudinally sliding door at the opening that has a protective function and allows for observation of the internal situation to a certain extent. The door can be automatically opened or closed by a winding assembly, and the winding assembly can be locked by an automatic locking assembly, so that the door is smoothly locked and stopped, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated spot welding machine for motor rotor production, comprising a support, a fixed door fixedly installed at the upper part of the front opening of the support, a movable door longitudinally slidably connected at the lower part of the front opening of the support via a slide rail, the top of the movable door being suspended by a winding assembly at the top of the support via a steel rope, an intermediate wheel installed in the middle of the top of the support, a steel rope supported on the outer wall of the intermediate wheel, and an automatic locking assembly installed at the end of the winding assembly.

[0006] Preferably, the bottom of the opening on the front of the support is connected to a bottom buffer strip by several springs, and the bottom buffer strip is located directly below the movable door.

[0007] Preferably, the movable door includes a door frame slidably connected within a slide rail, and a protective cover is installed on the inner side wall of the door frame. The protective cover is made of a material that is resistant to high temperatures, protects against welding radiation, and allows for a certain degree of visibility.

[0008] Preferably, a rotating workbench is installed on the lower part of the inner sidewall of the support, and an electric welding assembly is installed on the top of the inner sidewall of the support via a displacement assembly and a second electric telescopic rod.

[0009] Preferably, the winding assembly includes a winding roller mounted on top of the support via a roller frame, wherein the power input end of the winding roller is connected to the power output end of an electric motor.

[0010] Preferably, the automatic locking assembly includes a gear fixedly mounted on the end of the take-up roller, a rack meshing with the outer wall of the gear, a first electric telescopic rod mounted on the top of the support, and a rack mounted on the end of the first electric telescopic rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model discloses a movable door with a longitudinal sliding connection at the opening in the field of motor rotor production technology. The door has a protective function and allows for observation of the internal situation to a certain extent. The movable door can be automatically opened or closed by a winding assembly, and the winding assembly can be locked by an automatic locking assembly, so that the movable door is smoothly locked.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 The figure shows an automated spot welding machine for producing motor rotors, including a support 1. A fixed door 2 is fixedly installed at the upper part of the front opening of the support 1. A movable door 4 is longitudinally slidably connected to the lower part of the front opening of the support 1 via a slide rail 3. The top of the movable door 4 is suspended by a winding assembly at the top of the support 1 via a steel rope 8. An intermediate wheel 9 is installed in the middle of the top of the support 1. The outer wall of the intermediate wheel 9 is supported by the steel rope 8. An automatic locking assembly is installed at the end of the winding assembly. The movable door 4, which has a protective function and allows for observation of the internal situation to a certain extent, is longitudinally slidably connected at the opening of the motor rotor production field disclosed in this utility model. The movable door 4 can be automatically opened or closed by the winding assembly, and the winding assembly can be locked by the automatic locking assembly, so that the movable door 4 is smoothly locked.

[0020] Furthermore, at the bottom of the opening on the front of the support 1, a bottom buffer strip 5 is connected by several springs 6. The bottom buffer strip 5 is located directly below the movable door 4, serving as a buffer to prevent the movable door 4 from suddenly falling and rigidly colliding with the support 1 and causing damage. Furthermore, the movable door 4 includes a door frame 401 slidably connected within the slide rail 3. A protective cover 402 is installed on the inner wall of the door frame 401. The protective cover 402 is made of a material that is resistant to high temperatures, protects against welding radiation, and allows for a certain degree of visibility, providing excellent protection and allowing for some observation of the internal welding process during welding. Furthermore, a rotating worktable 7 is installed on the lower part of the inner wall of the support 1. A welding assembly 16 is installed on the top of the inner side wall of the support 1 via a displacement assembly 18 and a second electric telescopic rod 17 for easy welding. Furthermore, the winding assembly includes a winding roller 12 installed on the top of the support 1 via a roller frame 11. The power input end of the winding roller 12 is connected to the power output end of a motor 10 for easy winding or unwinding of the steel rope 8. Furthermore, the automatic locking assembly includes a gear 13 fixedly installed at the end of the winding roller 12. A rack 14 is meshed with the outer side wall of the gear 13. A first electric telescopic rod 15 is installed on the top of the support 1. The rack 14 is installed at the end of the first electric telescopic rod 15 for easy self-locking.

[0021] In this solution, during use, the opening of the motor rotor production technology disclosed in this utility model is longitudinally slidingly connected with a movable door 4 that has a protective function and allows for observation of the internal situation to a certain extent. The movable door 4 can be automatically opened or closed by the winding assembly, and the winding assembly can be locked by the automatic locking assembly, so that the movable door 4 is smoothly locked. When it is necessary to place the workpiece to be welded on the rotary table 7, the external power supply controls the first electric telescopic rod 15 to retract through the external switch, so that the rack 14 disengages from the gear 13. At this time, the winding assembly releases its self-locking, and the external power supply controls the electric... When the machine 10 rotates forward, it drives the winding roller 12 to rotate clockwise to wind up the steel rope 8, so that the movable door 4 is lifted upward. The movable door 4 slides upward along the slide rail 3 until it exposes the opening of the support 1. Then, the self-locking component locks the winding component. When it is placed and welding is required, the self-locking component is released from the self-locking component. Similarly, the control motor 10 reverses to make the movable door 4 fall back, blocking the opening. Then, the self-locking component locks the winding component again. (The rotating table 7, motor 10, first electric telescopic rod 15, welding component 16, second electric telescopic rod 17 and displacement component 18 are all existing products on the market.)
