Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a motor core laser welding machine with an automatic flexibility correction device. Background Art

[0002] In the prior art, the production of motor stator core includes 6 steps: stamping and punching - riveting and lamination - pre-pressing - pressure holding - welding - testing, etc. The current production process is that each step is a separate production process, and each step requires special equipment for processing, and then the material flow is carried out manually after testing.

[0003] However, the original motor core manufacturing process has the following deficiencies:

[0004] 1. Each process is manufactured separately, and a lot of repetitive work time leads to serious waste of manpower;

[0005] 2. The welding equipment adopts a single-station mode, and the production capacity is low;

[0006] 3. The motor core position deviation often occurs during welding, which cannot guarantee the welding quality;

[0007] 4. Direct stamping during pressure holding operation has strict requirements on the bottom setting, which can easily cause excessive force on the bottom and cause bottom breakage. Utility Model Content

[0008] The utility model aims to provide a motor core laser welding machine with an automatic flexibility correction device, which can effectively solve the problems in the background technology.

[0009] A motor core laser welding machine with an automatic flexibility correction device, the welding machine comprises a frame, a rotating welding base is arranged on the frame, a plurality of core welding placement components are evenly arranged on the rotating welding base, the core welding placement component comprises a telescopic shaft passing through a sleeve shaft on the rotating welding base, a docking plate is fixedly arranged at one end of the telescopic shaft, a buffer spring is arranged between the docking plate and the sleeve shaft, a motor core placement frame is arranged at the upper end of the docking plate, and an inflatable shaft is arranged in the middle of the motor core placement frame.

[0010] As a further improvement, the welding machine also includes a pressing welding assembly, which includes a first laser welding mechanism, a second laser welding mechanism, a third laser welding mechanism and a pressing mechanism thereof for performing a pressing operation on the motor stator core.

[0011] As a further improvement, the first laser welding mechanism and the second laser welding mechanism are respectively arranged on the left and right sides of the pressing mechanism, and the third laser welding mechanism is arranged right in front of the pressing mechanism.

[0012] As a further improvement, the first laser welding mechanism and the second laser welding mechanism respectively include a slide, and the slide is connected with an electric X-axis that drives the slide to move along the X-axis and an electric Y-axis that drives the slide to move along the Y-axis, and the slide is also provided with a first laser welding gun.

[0014] As a further improvement, the third laser welding mechanism includes a third slide and a lifting rod fixed on the third slide, and the end of the lifting rod is connected to the third welding gun through a third welding gun angle adjustment mechanism.

[0015] Technical effects and advantages of the utility model:

[0016] 1. Through the new press-fitting and welding methods, the core is quickly laser welded by laser welding under pressure. Since the welding is carried out under sufficient pressure throughout the process, the deformation of the product caused by thermal stress is avoided. Secondly, the core circle is effectively fixed in the center through the air shaft, and the position correction is effectively guaranteed, as well as fast laser welding;

[0017] 2. Laser welding greatly reduces the heat-affected zone of welding, and adopts rapid welding under pressure-maintaining state, which effectively curbs the deformation caused by heat accumulation. In addition, with the non-media and non-contact welding method of laser welding, the surface finish of the product weld has been greatly improved. The multi-station rotation alternating production method has greatly improved the production efficiency and reduced the floor space.

[0018] 3. The objective situation of batch and efficient welding of motor stator cores has been solved. By designing the device into a multi-station mode and automatically rotating under online pressurization and compression, the problem of low original production capacity has been solved.

[0019] 4. By setting a buffer spring on the rotary welding base, the base can be guaranteed to be less damaged by pressure under the pressure-maintaining state. BRIEF DESCRIPTION OF THE DRAWINGS
