Description

Technical Field

[0001] The invention belongs to the technical field of electrical machinery, and in particular relates to a horizontal slot wedge expander for a motor stator. Background Art

[0002] The production of motor stators requires winding, embedding, shaping, binding and other production processes, followed by slot wedge expansion, and pressing the slot wedge paper so that it does not protrude from the inner diameter of the stator. The current slot wedge expansion machine is mainly used to expand the stators of small motors such as refrigerators and home appliances. During the stator expansion process, operators are usually required to put the stator into the slot wedge expansion machine, and then manually take out the stator after the expansion is completed. The low efficiency of loading and unloading slows down the production rhythm, and a large amount of manpower is required for processing and production. During the loading and unloading process, it is easy for human errors to fail to achieve the expected slot wedge expansion effect, and the yield rate of the stator is difficult to guarantee. In addition, the existing slot wedge expansion machines also have problems such as inconvenient mold replacement and the expansion amount of the expansion plate cannot be adjusted. Summary of the invention

[0003] The purpose of the present invention is to provide a motor stator horizontal slot wedge expanding machine with convenient mold replacement, adjustable expansion amount and high automation.

[0004] The technical solution of the present invention is: a horizontal slot wedge expansion machine for a motor stator, characterized in that: a sliding guide rail is installed on one side of the equipment frame to support a stator device, and a working panel is installed on the other side of the equipment frame; a slot wedge expansion cylinder with adjustable stroke, a mold support seat and a stator push-pull cylinder are installed on the working panel, the stator push-pull cylinder is fixedly connected to the stator support device through a floating joint, the slot wedge expansion mold is positioned by a cylindrical pin and then pressed onto the mold support seat by a pressure plate, and the slot wedge expansion cylinder piston rod is connected to the slot wedge expansion mold expansion shaft.

[0005] The stator supporting device is provided with a guide key and two roller base plates on the sliding plate, the groove at the lower end of the roller base plate is slidably matched with the guide key, a trapezoidal nut is installed in the middle of each roller base plate and is threadedly connected with a trapezoidal lead screw, a lead screw fixing support and a lead screw supporting support are respectively installed at the left and right ends of the trapezoidal lead screw, the lead screw fixing support and the lead screw supporting support are fixedly connected to the left and right sides of the sliding plate, the anti-rotation block is fixedly connected to the lead screw supporting support, an adjustable handle is installed on the anti-rotation block, an axle seat is provided on the roller base plate to support the roller, and the stator is placed between the two rollers.

[0006] Due to the adoption of the above technical solution, the stator is placed on the stator support device, and the stator push-pull cylinder drags the stator support device to drag the stator from the loading and unloading station to the expansion station. The piston rod of the stroke-adjustable slot wedge expansion cylinder extends to drive the expansion shaft to move horizontally, thereby realizing the expansion of the slot wedge paper. After the expansion is completed, the piston rod of the stroke-adjustable slot wedge expansion cylinder retracts, and the stator push-pull cylinder drags the stator support device to drag the stator from the expansion station to the loading and unloading station, thereby completing the entire stator expansion process. When the expansion amount does not meet the requirements, the expansion amount of the slot wedge expansion mold is changed by changing the stroke of the stroke-adjustable slot wedge expansion cylinder. When the stator model is changed, the slot wedge expansion mold needs to be replaced. At this time, the tightening handle on the pressure plate is loosened, the pressure plate is pulled out, the slot wedge expansion mold is hoisted out as a whole, and then the new mold is installed on the mold support seat. The mold is pressed with the pressure plate and the tightening handle is tightened. When the stator model is changed, the outer diameter of the stator also changes accordingly, and the stator support device needs to be adjusted at this time. Loosen the locking handle on the anti-rotation block, turn the trapezoidal screw, adjust the distance between the two roller base plates, make the stator center concentric with the slot wedge expansion mold, and tighten the locking handle on the anti-rotation block after adjustment. The entire mold replacement process is quick and convenient.
