Description

Technical Field

[0001] This invention belongs to the field of electrical machinery and equipment technology, specifically relating to a fixing and issuing device for a flat wire stator card issuing and straightening machine. Background Technology

[0002] After the flat stator hairpins are twisted in pairs, they need to be cut to the same height to facilitate subsequent welding. Therefore, the flat stator hairpin trimming machine is used to cut stator hairpins of irregular heights to the same height. One challenge in cutting hairpins of varying heights from flat stators is guiding them into the cutting tool. Twisting the flat stator hairpins in pairs inevitably causes springback, resulting in non-ideal dimensions and deviations after twisting. Currently, the method for guiding the hairpins in pairs into the cutting tool involves machining a large chamfer at the tool's inlet. This chamfer eliminates the dimensional inaccuracies caused by the springback. If the stator hairpin wire has good twist quality and a small deviation, it can be guided into the cutting tool through the chamfer. However, if the twist deviation is large, the hairpin wire cannot enter the cutting tool smoothly, resulting in some stator hairpin wires not being cut and causing the stator to be scrapped. In actual production, manual inspection is often required to ensure that all stator hairpin wires can be inserted into the cutting tool, reducing the level of automation and lowering the company's production efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the above-mentioned technologies and provide a fixed card issuing device for a flat wire stator card issuing and straightening machine with a high degree of automation and production efficiency.

[0004] To solve the above technical problems, the technical solution adopted in this invention is as follows: the fixed seat is fixedly connected to the X-axis cam disk; the Y-axis cam disk is fitted with the inner ring of the bearing; the outer ring of the bearing is fitted with the X-axis cam disk; the Y-axis cam disk rotates within the cavity formed by the fixed seat and the X-axis cam disk; the friction damping plate is fixedly connected to the limiting post; the limiting post is fixedly connected to the X-axis cam disk; the Y-axis cam disk roller is rolled in conjunction with the Y-axis cam disk cam groove; the Y-axis cam disk roller is fixedly connected to the guide rail fixed seat; the guide rail fixed seat is slidably fitted with the X-axis cam disk slide groove; the guide rail is fixedly connected to the guide rail fixed seat; the two left and right gripper fixed seats are fixedly connected to the two sliders of the guide rail; the left and right grippers are fixedly connected to the left and right gripper fixed seats respectively; the X-axis cam disk roller is rolled in conjunction with the X-axis cam disk cam groove; the other end of the X-axis cam disk roller is fixedly connected to the gripper fixed seat; the reducer is fixedly connected to the fixed seat; the reducer shaft is fixedly connected to the Y-axis cam disk; the motor is fixedly connected to the reducer; and the stator inner hole is coaxially fitted with the fixed seat.

[0005] Beneficial effects This invention employs a double-cam mechanism, using a specific mechanical structure to drive the grippers along a designated path to clamp the hairpin thread. The grippers hold the hairpin thread and move it to a specific position, ensuring accurate positioning and thus guaranteeing its smooth entry into the cutting tool. This invention improves the stability and automation level of the flat wire stator hairpin trimming machine while reducing production costs for manufacturers. Attached Figure Description

[0007] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0008] like Figure 1-5As shown, a fixing device for a flat wire stator clipping machine comprises a fixing seat 9 fixedly connected to an X-axis cam disk 6, a Y-axis cam disk 8 engaged with the inner ring of a bearing 7, and an outer ring of the bearing 7 engaged with the X-axis cam disk 6. The Y-axis cam disk 8 rotates within the cavity formed by the fixing seat 9 and the X-axis cam disk 6. A friction damping plate 4 is fixedly connected to a limiting post 14, which is also fixedly connected to the X-axis cam disk. A Y-axis cam disk roller 10 rolls with a Y-axis cam disk cam groove 17, and is fixedly connected to a guide rail fixing seat 5. The guide rail fixing seat 5 is connected to the X-axis cam disk sliding groove 19. The guide rail 3 is fixedly connected to the guide rail fixing seat 5. The left jaw fixing seat 20 and the right jaw fixing seat 13 are fixedly connected to the two sliders of the guide rail 3. The left jaw 2 and the right jaw 1 are fixedly connected to the left jaw fixing seat 20 and the right jaw fixing seat 13 respectively. The X-axis cam disk roller 11 is in rolling engagement with the X-axis cam disk cam groove 16. The other end of the X-axis cam disk roller 11 is fixedly connected to the right jaw fixing seat 13. The reducer 15 is fixedly connected to the fixing seat 9. The shaft of the reducer 15 is fixedly connected to the Y-axis cam disk 8. The motor 12 is fixedly connected to the reducer 15. The inner hole of the stator 18 is coaxially engaged with the fixing seat 9.

[0009] The working steps of a fixing and issuing device for a flat wire stator card issuing and straightening machine are as follows: like Figure 1 , 5 As shown, the rotation of motor 12 drives the rotation of reducer 15, the rotation of reducer 15 drives the rotation of Y-axis cam disk 8, the rotation of Y-axis cam disk cam groove 17 drives the movement of Y-axis cam disk roller 10, and the Y-axis roller disk roller 10 drives the guide rail fixing seat 5 to move forward in the cavity formed by X-axis roller disk slide groove 19 and friction reducing plate 4, forming Y-axis movement. The forward movement of guide rail fixing seat 5 drives guide rail 3, right gripper fixing seat 13, right gripper 1, and left gripper 2 to also perform Y-axis movement. At the same time, the X-axis cam disk roller 11 on left gripper fixing seat 20 and right gripper fixing seat 13 moves along the trajectory of X-axis cam disk cam groove 16. Figure 4 First, the Y-axis motion is performed, followed by the X-axis motion. During the X-axis motion, the X-axis cam disk roller 11 drives the gripper fixing seat 13 to perform X-motion through the guide rail 3, and drives the right gripper 1 and left gripper 2 fixed thereon to move along the trajectory of the X-axis cam disk cam groove 16 at the same time. The right gripper 1 and left gripper 2 fix the hairpin line of the stator 18, so that it can be smoothly entered into the cutting tool.

Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solutions of the present invention are also within the protection scope of the present invention.
