Description

Technical Field

[0001] This utility model belongs to the technical field of motor processing equipment, specifically relating to a grinding device for resistance welding grinding electrodes. Background Technology

[0002] Resistance welding involves pressing electrodes together to conduct electricity, generating resistance heat to weld overlapping products together. Prolonged resistance heat can cause electrode wear and adhesion of oxides to the product surface, requiring the electrode cross-section to be ground.

[0003] Currently, conventional resistance welding equipment relies on manual grinding of electrodes using files, sandpaper, and scrapers. This method has the following drawbacks: a) If implemented in an automated resistance welding line, electrode grinding will be very slow, increasing cycle time. b) Excessive electrode wear leads to frequent replacements, resulting in high direct and indirect costs. c) Inconsistent grinding amounts per cycle cause inconsistent weld quality. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for resistance welding grinding electrodes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grinding device for resistance welding electrodes includes a driving unit, a transmission unit, and a grinding unit. The transmission unit is installed at one end of the driving unit, and the grinding unit is installed at the end of the transmission unit away from the driving unit. The grinding unit includes an upper grinding assembly and a lower grinding assembly, which are respectively installed on both sides of the transmission unit. The upper grinding assembly and the lower grinding assembly have the same structure.

[0007] By adopting the above technical solution: during processing, the electrodes are installed on both sides of the device, and then the drive unit is started. Under the drive of the drive unit, the transmission unit drives the upper and lower grinding components of the grinding unit to move simultaneously, thereby grinding the motors on both sides at the same time, ensuring the cleanliness of the electrode cross-section. This not only has high working efficiency, but also good processing stability.

[0008] Preferably, the upper grinding assembly includes an eccentric cam and a base grinding disc, the center of the eccentric cam is connected to the transmission part, and the base grinding disc is mounted on the side of the eccentric cam away from the transmission part.

[0009] By adopting the above technical solution, during processing, the grinding components located on both sides of the transmission part are used to grind the cross-sections of the two motors simultaneously, and the grinding amplitude is adjusted by adjusting the rotation of the eccentric cam, thereby ensuring the precision and quality of grinding.

[0010] Preferably, the surface of the base grinding disc is bonded with sandpaper via Velcro.

[0011] By adopting the above technical solution, sandpaper bonded with Velcro is not only convenient for sanding, but also easy to replace, resulting in high work efficiency.

[0012] Preferably, one side of the eccentric cam is connected to the transmission unit via a first key shaft, and the other side is connected to the base grinding disc via a second key shaft.

[0013] By adopting the above technical solution, the first key shaft and the second key shaft are used to connect the transmission part and the base grinding disc, respectively, to ensure the accuracy of the transmission.

[0014] Preferably, the transmission unit includes a housing, a first pulley, a second pulley, and a transmission belt. The first pulley and the second pulley are located at opposite ends inside the housing. The first pulley is connected to the drive unit, and the second pulley is connected to the grinding unit. The first pulley and the second pulley are connected by the transmission belt.

[0015] By adopting the above technical solution: during processing, under the drive of the drive unit, the first pulley drives the second pulley to rotate through the transmission belt, thereby driving the eccentric cam to rotate through the first key shaft, so as to achieve grinding of the electrode cross-section.

[0016] Preferably, the drive unit includes a drive motor and an output shaft. The drive motor is fixedly mounted on one side of the housing, and the output end of the drive motor is connected to the output shaft, which is connected to the first pulley.

[0017] By adopting the above technical solution: under the drive of the drive motor, the output shaft drives the first pulley to rotate, thereby driving the grinding part to work.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] This device employs a linked design of the drive unit, transmission unit, and grinding unit (including symmetrical upper / lower grinding components) to grind two electrodes simultaneously, significantly improving grinding efficiency and fully meeting the high-cycle requirements of automated production lines. It solves the efficiency bottleneck problem of manual grinding. The eccentric cam mechanism precisely adjusts the grinding amplitude, combined with key shaft transmission to ensure accuracy, effectively preventing over-grinding. Precise control reduces unnecessary electrode material consumption, significantly extending electrode lifespan and lowering direct and indirect costs associated with frequent electrode replacements. The mechanized synchronous grinding process ensures consistency in each grinding cycle, reliably guaranteeing the electrode end face shape, flatness, and cleanliness. This stabilizes the resistance heat distribution in the welding area, fundamentally improving the stability and reliability of product welding quality and reducing the defect rate.
