Description

Technical Field

[0001] The present application relates to the technical field of welding, and in particular to a welding tool for a water-cooled motor housing. Background Art

[0002] When the motor is running, it will generate a lot of heat. At this time, the heat needs to be dissipated in time to ensure the normal operation of the motor. If the motor always works at a higher operating temperature, the service life will be greatly reduced. At the same time, the working efficiency and energy consumption will be greatly reduced. Therefore, the motor is usually equipped with a heat dissipation device, or the heat dissipation structure is designed by itself. Most of the motors on the market are water-cooled motors. As the name implies, the heat dissipation of the motor is accelerated by water circulation. The water-cooled motor usually has a water cooling channel on the motor housing, and has a water inlet and a water outlet. The water inlet and the water outlet are connected to the water cooling channel. The motor housing of this structure is provided with an inner shell and an outer shell. The inner shell is embedded in the outer shell, and the outer surface of the inner shell is interference fit tightly against the inner surface of the outer shell. In addition, welding is performed at the joint between the outer end faces of the inner shell and the outer shell to ensure the sealing of the water cooling channel.

[0003] In the process of welding the motor casing, the motor body needs to be fixed to ensure the welding quality during the motor welding process, thereby ensuring the sealing effect between the welded inner and outer shells. Therefore, we proposed a water-cooled motor casing welding tool to solve the above-mentioned problems. Utility Model Content

The water-cooled motor housing welding tooling drives the fixed column 10 to adjust the longitudinal height synchronously by rotating the screw 31. When the fixed column 10 moves, the limit plate 5 is synchronously driven to compress the spring 4 under the transmission of the connecting rod 9 and the connecting plate 8, and then the limit plate 5 is synchronously driven to fix the motor body clamped on the outer wall of each limit plate 5 through the expansion and contraction of the spring 4.

Since the connecting rod 9 is in an inclined state, and the inclination angle of the connecting rod 9 is in a state that the limit plate 5 can only move horizontally, and the limit plate 5 is limited within the range of movement.
