Description

Technical Field

[0002] The automobile generator is the main power source of the car. Its function is to supply power to all electrical equipment (except the starter) and charge the battery when the engine is running normally. On the basis of the three-phase stator winding of the ordinary AC generator, the number of winding turns is increased and the terminal is led out, and a set of three-phase bridge rectifier is added. At low speed, the original winding and the increased winding are connected in series to output. The automobile generator has many parts. When producing and processing it, it is necessary to use positioning tooling to limit and fix the generator, and fix it firmly on the processing table to facilitate subsequent processing.

[0003] The main purpose of the positioning tool is to clamp and limit the automobile generator parts to keep them stable, so as to facilitate subsequent processing. However, most positioning tools use multiple transmission parts to control the movement of the clamping part, which is power-consuming and not practical. In addition, during the long-term contact between the automobile generator parts and the clamping part, the surface of the clamping part is obviously damaged. Therefore, after a gap is generated, the subsequent clamping is not firm enough. For this reason, a positioning tool for automobile generator processing is designed. Utility Model Content

The utility model provides a positioning tool for automobile generator processing, which is provided with a fixing column 9, a processing panel 10, a clamping plate 12 and an auxiliary rod 14. The second silicone plate 15 is connected to the first silicone plate 13 by relying on the plurality of auxiliary rods 14, and the first silicone plate 13 and the second silicone plate 15 are both made of silicone material.

[0026] Working principle: Automobile generator manufacturing requires some parts. During the parts processing, it is necessary to use positioning tooling to clamp the automobile parts. First, the staff can place the automobile parts on the surface of the processing panel 10, and then the staff can start the stepper motor 2. The bottom surfaces of the two first silicone plates 13 are in contact with the surfaces of the processing panel 10 respectively. After the stepper motor 2 is started, it will drive the gear 4 to rotate, thereby driving the two racks 8 meshing with it to move. After the gear 4 rotates counterclockwise, the two extension plates 7 move relative to each other, and the positioning frame 6 moves at one end of the smooth rod 5 respectively, driving the two second silicone plates 15 to move relative to each other.

The bottom of the processing panel 10 is supported by two fixed columns 9. When the rack 8 moves, the force will be transmitted to the positioning frame 6, and the positioning frame 6 will move at one end of the smooth rod 5. When the stepper motor 2 rotates clockwise, it will drive the two racks 8 to move toward each other. Therefore, during the movement of the two second silicone plates 15, automobile generator parts of different diameters can be clamped, which increases the scope of use of the positioning tooling.
