Description

Technical Field

[0001] The utility model relates to the technical field of positioning punching sheets, in particular to a hole positioning device for stator punching sheet forming. Background Art

[0002] The production steps of stator punching sheets are as follows: first, the cutting machine cuts the cylindrical metal rods into discs, then the operator collects the discs, takes the discs to the punching machine for drilling, and then glues the punched punching sheets into the stator core.

[0003] Since the discs fall randomly after being cut, the operators collect them manually and the punching device punches holes one by one, so the work efficiency is low, and the cut discs may have burrs or metal debris. If they are not cleaned in time, the bottom surface of the disc will be uneven when placed on the punching station, which will reduce the punching accuracy and cause deviations in the hole position.

[0013] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0014] like Figure 1-3 The hole positioning device for stator punching forming shown in the figure comprises a body 1 and a collecting assembly installed at one end of the body 1, the body 1 comprises a blanking plate 2 and a bracket 7, the blanking plate 2 is fixedly mounted on the bracket 7, the collecting assembly comprises a collecting bin 4 and an electromagnet 8, the electromagnet 8 is fixedly mounted on the outer wall of the collecting bin 4, two side panels 3 are fixedly mounted on the bottom end of the blanking plate 2, the bottom of the side panels 3 is fixedly connected to the bracket 7, a grinding wheel 5 is installed between the two side panels 3, and the collecting bin 4 is installed on the side of the side panel 3 away from the blanking plate 2. A motor 6 is fixedly mounted on the outer wall of one of the side panels 3, the output end of the motor 6 passes through the side panel 3 and is fixedly connected to the grinding wheel 5, a transition plate is arranged between the grinding wheel 5 and the bottom end of the blanking plate 2, and the transition plate is fixedly connected to the bottom of the blanking plate 2.

[0015] An inclined plate 12 is fixedly installed between the ends of the two side plates 3 away from the blanking plate 2, and the bottom edge of the inclined plate 12 is fixedly connected to one end edge of the collecting bin 4, and a grid plate 11 is fixedly installed on the inner wall of the collecting bin 4 away from the inclined plate 12. A plurality of springs 10 are fixedly installed at the bottom of the collecting bin 4, and a receiving plate 9 is fixedly installed above the plurality of springs 10, and the edge of the receiving plate 9 fits the inner wall of the collecting bin 4. A gap is left between the grid plate 11 and the inner wall of the collecting bin 4 away from the inclined plate 12, and the electromagnet 8 is installed on the outer wall of the collecting bin 4 close to the grid plate 11. A plurality of notches are opened through the outer wall of the grid plate 11.

[0016] Embodiment: The disc punch cut from the cutting machine slides down from the unloading plate 2, moves to the top of the grinding wheel 5 through the transition plate, and the motor 6 drives the grinding wheel 5 to rotate, and the grinding wheel 5 drives the punch to move toward the inclined plate 12. The grinding wheel 5 can also grind the bottom of the punch to remove burrs and uneven parts. Then the punch passes through the inclined plate 12 and falls onto the receiving plate 9 inside the collecting bin 4. After the number of punches inside the collecting bin 4 reaches a certain number, the electromagnet 8 is started to generate an adsorption force on the punches. The edges of multiple punches are offset against the outer wall of the grid plate 11 due to the suction force of the electromagnet 8, so that the edges of the stacked multiple punches are aligned. At the same time, the metal debris between the punches is sucked away by the electromagnet 8, and the debris falls to the bottom of the collecting bin 4 through the gap in the grid plate 11.

[0017] A punching device is provided above the collection bin 4. Multiple punches are aligned at their edges due to the suction of the electromagnet 8, so the center position of the disc punch is fixed. Therefore, the punching device can be installed in a fixed position. After the punches are aligned, they are pressed down to punch holes. This not only completes the positioning of the disc punches, but also allows punching of punches in batches, thereby improving work efficiency. When the punching device is pressed down to punch holes, the receiving plate 9 is pressed down, and the spring 10 is compressed and deformed, so that the punch is buffered when it is pressed, preventing the punch from breaking due to excessive downward pressure of the punching device.

[0018] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
