Abstract

The invention discloses a novel block type circle splicing welding machine for stator iron cores. The machine comprises a case, a safety cover, a worktable top, a stator tightening mechanism, a statorend surface shaping mechanism, a stator welding mechanism, the stator iron cores, an indicator light and a control panel, wherein the case and the safety cover are integrally connected; the stator tightening mechanism, the stator end surface shaping mechanism and the stator welding mechanism are mounted on the worktable top; the control panel controls the stator tightening mechanism, the stator end surface shaping mechanism and the stator welding mechanism to work; the stator tightening mechanism is used for fixing a plurality of stator iron cores; the stator end surface shaping mechanism isused for pressing and aligning the end surfaces of the plurality of stator iron cores; the plurality of stator iron cores are welded into a hole through the stator welding mechanism. According to themachine, the processes from circle splicing, shaping to welding are automatically carried out; the circular degree of an inner circle of the stator iron core subjected to circle splicing completely meets the requirement on the circular degree of an inner circle of a motor; and meanwhile, the production efficiency is greatly improved; and the machine is high in practicability and wide in applicablescope.

[0002] When multiple segmented stator cores are assembled into a whole, they need to be rounded and welded; special tooling equipment is required for rounds and welding; currently the segmented stators on the market are mainly rounded by mouse Cage-type round-up and manual hoop-type round-up are the main methods. Use the above methods to round up the iron core before welding; however, the squirrel-cage round-up welding method is based on the roundness of the outer circle, which does not meet the inner roundness of the motor. According to the requirement of standard height, manual hoop-type rounding is not conducive to automation, resulting in low production efficiency and high cost; at the same time, in the process of manufacturing and installing the stator core, there will be a problem of inconsistent height, which makes the end face not neat enough. If the end faces are not flush, it will affect the welding of the subsequent PCB board. To solve this problem, people usually use a whole piece of pressure plate to extrude the stator core. However, the stator core has a certain height difference during production. As a result, the entire pressure plate cannot squeeze the lower stator core, and it is difficult to achieve the desired effect, which affects the progress of the down-moving process; it is urgent to develop a model that can automatically make rounds, and can automatically align the end faces after being rounded. After pressing, it can carry out all-round welding, and the new block-type stator core round welding machine with high degree of automation will replace the current production method
