[0001] The utility model belongs to the technical field of electric tool processing application, and specifically relates to a multi-station positioning device for processing electric tool parts, which is used for fixing different electric tool parts to be processed during deep processing, or for clamping and auxiliary fixing during assembly. Background Art

[0002] Power tools are tools that use a transmission mechanism to drive the working head. During the processing and manufacturing of the components of power tools, such as grinding, drilling or assembly, the components need to be fixed to cooperate with grinding equipment, drilling equipment or assembly equipment to complete the safe and efficient processing and assembly of power tool components.

The utility model provides a multi-end face positioning processing device in the field of positioning processing technology, which can simultaneously position and fix parts with two different end faces on the same fixture, saving time and effort and efficient processing. The positioning fixture is small in size. When the part is placed on the positioning fixture, the sensor senses that the part is in place, and the cylinder automatically extends to clamp the part. The operation is simple and the positioning accuracy is high.

[0004] (2) Application No. / Patent No. 202320657524.2 discloses a multi-station adjustable shaft processing positioning device, including a fixed seat, an inner sliding seat connected to the inner sliding cavity, a guide plate fixedly arranged at the rear end of the inner sliding seat, side opening plates fixedly arranged on both sides of the fixed seat through a telescopic rod, and a clamping seat fixedly arranged on the inner side of the side slide plate; a guide plate and a support plate are respectively arranged at both ends of the inner sliding seat of the utility model, and the shaft can be supported and pushed by the guide plate and the support plate, the shaft extends from one end of the support plate, and then the side slide plate slides forward inside the side opening plate to a position opposite to the shaft, and then the telescopic rod drives the side opening plate to move inward, and the processing section of the shaft is clamped and fixed by the clamping seat and the clamping arm, so that during processing, the processing section is more stable and the processing accuracy is high, and the shaft can also be flipped, and the outer gear ring can be driven to rotate by the driving gear, thereby driving the shaft to rotate, and no manual flipping is required, and the processing efficiency is high.
