Description

Technical Field

[0001] This utility model relates to the field of stamping device technology, specifically a quick-change motor stator stamping device. Background Technology

[0002] In the motor production process, the motor stator stamping device is the key equipment for forming the stator core. Through the stamping die, raw materials such as silicon steel sheets are continuously punched and stacked to form a stator core with a specific slot structure. The adaptability and replacement efficiency of the die directly determine the production flexibility and batch switching speed of the motor stator.

[0003] Based on the above, the inventors have discovered the following problems: the existing mold fixing method of motor stator stamping device generally adopts the structure of "bolt fastening + positioning pin assistance". The mold and the stamping worktable are rigidly connected by multiple high-strength bolts distributed in the circumference. When changing the mold, multiple bolts need to be removed and the mold needs to be disassembled. After installing the new mold, these bolts need to be reinstalled. This method relies on special tools and the bolt disassembly / tightening is time-consuming. In multi-batch small-volume production scenarios, the mold change time seriously compresses the effective production time.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a fast mold change motor stator stamping device in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-change motor stator stamping device to solve the problem mentioned in the background art that the existing motor stator stamping devices generally use "bolt fastening + positioning pin assistance" for mold fixing.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A quick-change motor stator stamping device includes a main body, a fixing mechanism, and a mold mechanism. The main body includes a stamping machine, and a stamping table is fixedly installed on the bottom side of the stamping machine. The fixing mechanism includes a pair of fixing plates, which are respectively connected to the bottom end of the stamping head of the stamping machine and the upper end of the stamping table. A transmission box is installed at the center of the facing surfaces of the pair of fixing plates. Movable slots are opened on both sides of the facing surfaces of the pair of fixing plates located in the transmission boxes. Screws are rotatably connected inside the movable slots. L-shaped moving blocks are threadedly connected to the screws. The pair of L-shaped moving blocks are mirror images of each other. The mold mechanism includes a lower mold base and an upper mold base, which are respectively disposed on the facing surfaces of the pair of fixing plates. Through slots are opened at the opposite ends of the lower mold base and the upper mold base. Slots are opened on both sides of the through slots. The slots are engaged with one end of the L-shaped moving blocks.

[0007] Furthermore, a pair of T-shaped limiting grooves are provided on the opposing surfaces of the fixing plate, and a pair of T-shaped sliders are fixedly installed on the opposite ends of the lower mold base and the upper mold base. Each pair of T-shaped sliders is slidably connected to a pair of T-shaped limiting grooves at their corresponding positions.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the T-shaped limiting groove of the fixed plate and the T-shaped slider of the mold can slide together to guide the lower mold base and the upper mold base to accurately align with the fixed plate, avoid mold installation offset, and limit the vertical displacement of the mold, thereby improving the stability during stamping.

[0009] Furthermore, positioning grooves are fixedly installed on both sides of the upper end face of the lower mold base, and positioning rods are fixedly installed on both sides of the bottom end of the upper mold base, with the positioning grooves and positioning rods being slidably inserted into each other.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the positioning groove of the lower die base and the positioning rod of the upper die base can be inserted and matched, which can accurately align the upper and lower dies before stamping, ensure accurate stamping position, avoid scrapping of stator stamping parts due to die misalignment, and improve product qualification rate.

[0011] Furthermore, each of the transmission boxes is rotatably connected to a worm gear, and the two ends of the worm gear are respectively connected to the opposite ends of a pair of screws, with the threads of each pair of screws being arranged in opposite directions.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the worm gear in the transmission box is connected to a pair of screws with opposite screw threads. When the worm gear rotates, it can drive the screws on both sides to rotate synchronously, so that the L-shaped moving blocks move towards or away from each other, realizing the quick clamping or loosening of the mold and simplifying the operation steps.

[0013] Furthermore, a worm gear is rotatably connected to one side of the bottom of the transmission box, and the worm gear meshes with the worm wheel.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the meshing transmission between the worm and the worm wheel can convert the rotational force of the worm into the driving force of the worm wheel. Moreover, the worm wheel and worm structure has self-locking properties, which can prevent the screw from rotating on its own after the mold is fixed, ensuring that the mold is firmly fixed and avoiding loosening during stamping.

[0015] Furthermore, an adjustment knob is rotatably connected to one side of the fixing plate, and the central shaft of one end of the adjustment knob is connected to one end of the worm gear.

[0016] The advantage of adopting the above-mentioned further solution is that the adjustment knob on one side of the fixed plate is directly connected to the worm gear. The user can drive the worm gear by rotating the adjustment knob without the need for additional tools, making the operation convenient and further improving the mold changing efficiency.

[0017] Furthermore, a controller is installed on the upper side of one side of the stamping table, and a buffer mat is fixedly installed on the bottom side of both the stamping machine and the stamping table.

[0018] The beneficial effects of adopting the above-mentioned further solutions are that the controller of the stamping table can conveniently control the operating parameters of the stamping machine; the buffer mats at the bottom of the stamping machine and the stamping table can absorb the vibration generated during stamping, reduce equipment noise, protect the ground and equipment parts, and extend service life.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The main body of the quick mold change motor stator stamping device, the stamping machine and stamping table, provide the foundation for stamping operations. The fixing plate of the fixing mechanism supports the lower mold base and the upper mold base respectively. The rotating screw can drive the L-shaped moving block to slide along the movable groove. The mirror-set L-shaped moving block can be inserted into the slots of the lower mold base and the upper mold base from both sides to quickly fix the lower mold base and the upper mold base. The transmission box can integrate the transmission components to ensure synchronous drive of the screw, improve the mold fixing efficiency and stability, and realize quick mold change. The T-shaped limiting groove of the fixing plate and the T-shaped slider of the mold can slide and cooperate to guide the lower mold base and the upper mold base to accurately align with the fixing plate, avoid mold installation offset, and limit the vertical displacement of the mold, thereby improving the stability during stamping.

[0023] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a quick-change motor stator stamping device, including a main body 1, a fixing mechanism 2, and a mold mechanism 3. The main body 1 includes a stamping machine 101, and a stamping table 102 is fixedly installed on the bottom side of the stamping machine 101.

Each pair of T-shaped sliders 305 is slidably connected to a pair of T-shaped limiting grooves 203 at their corresponding positions. The T-shaped limiting grooves 203 of the fixing plate 201 and the T-shaped sliders 305 of the mold slide in a sliding fit, which can guide the lower die base 301 and the upper die base 302 to accurately align with the fixing plate 201, avoid mold installation offset, limit the vertical displacement of the mold, and improve the stability during stamping.

The worm gear 209 in the transmission box 205 is connected to a pair of screws 208, and the threads of the screws 208 are opposite. When the worm gear 209 rotates, it can drive the screws 208 on both sides to rotate synchronously, so that the L-shaped moving blocks 207 move towards or away from each other, realizing the quick clamping or loosening of the mold and simplifying the operation steps.

[0029] As an embodiment of this utility model, a controller is further installed on the upper side of one side of the stamping table 102, and a buffer mat is fixedly installed on the bottom side of both the stamping machine 101 and the stamping table 102.

[0030] Specifically, the working principle of this quick-change motor stator stamping device is as follows: In use, the lower die holder 301 is first slid along the T-shaped limiting groove 203 of the upper fixing plate 201 on the stamping table 102 via the T-shaped slider 305 to the designated position. Simultaneously, the upper die holder 302 is slid into position along the T-shaped limiting groove 203 of the bottom fixing plate 201 of the stamping head of the stamping machine 101 via the T-shaped slider 305. Then, rotating the adjusting knob 206 drives the worm gear 202 to rotate. The worm gear 202 meshes with the worm wheel 209 in the transmission box 205, driving the screw 208 with opposite threads at both ends to rotate synchronously, causing the L-shaped moving block 207 to move along the movable... The slots 204 move towards each other and engage with the slots 307 on both sides of the through slot 306 of the lower die holder 301 and the upper die holder 302, using the self-locking property of the worm gear to fix the die. During stamping, the press 101 drives the upper die holder 302 to descend, and the positioning rod 303 of the upper die holder 302 is inserted into the positioning slot 304 of the lower die holder 301 for precise alignment, stamping the stator material. The cushioning pad absorbs vibration, and the controller adjusts the stamping parameters. When changing the die, the adjustment knob 206 is rotated in the opposite direction to disengage the L-shaped moving block 207 from the slot 307, and the old die can be taken out along the T-shaped limiting slot 203. After replacing the new die, the above steps are repeated to complete the fixing.
