[0003] In the traditional pressing process, all the iron chips that make up the motor must be stacked one by one before they can be sent into the pressing machine for fixing and pressing. This stacking process requires the use of handling and transfer equipment, which increases the number of operation steps and reduces work efficiency. In addition, the iron chips are prone to shifting during handling, which requires additional adjustment steps and further affects work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical pressing machine for motor cores with a fastener that allows for direct stacking on the surface of the processing plate, and eliminates the need for handling or lifting during the removal process. The machine can be directly laid flat and removed, making the operation more convenient and labor-saving, and improving production efficiency. This can solve the problems mentioned in the background art.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The figure shows a vertical pressing machine for motor cores with a clipping machine, comprising a processing plate 1 and a positioning and clamping structure 2 on the top surface. The positioning and clamping structure 2 includes an adjusting plate 201. A circular plate 206 is rotatably connected to the bottom center of the processing plate 1 via a pin 209. Three annularly arranged fan plates 208 are fixedly connected to the outer wall of the circular plate 206. Three annularly arranged sliding cavities 203 are opened at the top of the processing plate 1. The vertically arranged adjusting plate 201 is slidably connected inside the sliding cavities 203. An arc-shaped clamping plate 202 is installed on the side of the adjusting plate 201 near the center of the processing plate 1, and the other side is connected to the adjacent side wall of the sliding cavity 203 via a compression spring 2011. An arc-shaped block 2010 is fixedly connected to the bottom of the adjusting plate 201 near the fan plate 208. An L-shaped swing rod 207 is fixedly connected to the outer wall of the circular plate 206 away from the fan plate 208.

[0022] It is worth noting that the L-shaped lever 207 is swung to drive the circular plate 206 to move circumferentially. During the rotation of the circular plate 206, the fan plate 208 can be driven to move circumferentially at the same time, thereby squeezing the arc block 2010 and pushing the adjusting plate 201 to slide horizontally in the sliding cavity 203. This allows the three adjusting plates 201 to move synchronously and change the appropriate spacing distance, which can limit and clamp a number of motor iron chips. First, the appropriate spacing distance is limited, and the iron chips are manually placed in to ensure that the motor iron chips are correctly positioned. Then, the pressure is applied by the pressure structure 3. After the pressure is applied, the L-shaped lever 207 is swung to release the limitation on the iron chips after pressure, so that the motor iron core can be taken out flat. There is no need to transport it to the surface of the processing plate 1 after traditional assembly. It can be directly stacked on the surface of the processing plate 1. Moreover, the removal process does not require lifting or carrying. It can be taken out directly by laying it flat, which is more convenient and less labor-intensive, and improves production efficiency.

[0023] Please see Figure 2 The arc-shaped clamping plate 202 is fixedly connected to two screws 205 near the side of the adjusting plate 201. The other end of the screws 205 slides through the adjusting plate 201. Two nuts 204 are threaded onto the screws 205 and are symmetrically arranged about the adjusting plate 201. By loosening the nuts 204, the distance between the adjusting plate 201 and the arc-shaped clamping plate 202 can be changed, which facilitates the limiting clamping of motor iron chips of different sizes, improves the practicality of the device, and through this fine adjustment of size, it fits the size of the iron chip better, thus facilitating the subsequent quick clamping and fixing of the motor iron chip.

[0024] Please refer to Figure 1 and Figure 2 The arc-shaped clamp 202 has a long groove on the side away from the adjustment plate 201. The embedded surface of the long groove has scale lines, which can identify the height of the assembled iron chip, ensuring a fixed number of assembled iron chips. It eliminates the need for continuous manual operation of a ruler for measurement, and the height can be clearly judged by visual inspection, making the operation more convenient and further improving efficiency.

[0025] See Figure 1 and Figure 3 A pressure structure 3 is provided on the outer side of the processing plate 1. The pressure structure 3 includes a U-shaped plate 301. The processing plate 1 is located at the bottom of the U-shaped plate 301. Several support rods 305 are fixedly connected to the bottom side wall of the U-shaped plate 301. A top plate 302 is fixedly connected to the top. A hydraulic cylinder 304 is installed on the top of the top plate 302. The output end of the hydraulic cylinder 304 slides through the top plate 302 and is connected to a forming frustum 303. The forming frustum 303 is located directly above the processing plate 1. When the hydraulic cylinder 304 is started, it can push the forming frustum 303 down to perform a stamping operation on the motor iron chip placed on the processing plate 1, ensuring that the iron chip is tightly stacked.

[0026] See Figure 2 and Figure 5The vertical end of the L-shaped rocker arm 207 is provided with a limiting structure 5, which includes a sleeve 502. The vertical end of the L-shaped rocker arm 207 is slidably connected to the sleeve 502. The bottom end of the sleeve 502 is connected to the horizontal end of the L-shaped rocker arm 207 through a tension spring 504. The outer wall of the sleeve 502 is fixedly connected with a protrusion 503. The front side wall of the processing plate 1 has two symmetrically arranged arc-shaped cavities 501. The inner side wall of the arc-shaped cavity 501 has a slot 505.

[0027] It is worth noting that when the L-shaped rocker arm 207 swings under the drive of the adjusting plate 201, the sleeve 502 slides at the vertical end of the L-shaped rocker arm 207. Due to the tension of the tension spring 504, the sleeve 502 always tends to move towards the processing plate 1. When the sleeve 502 moves to the position of the arc cavity 501, the protrusion 503 is squeezed by the inner wall of the arc cavity 501 and then slides along the trajectory of the arc cavity 501 until the protrusion 503 is stuck in the slot 505, thus achieving the limiting function, ensuring the stability of the L-shaped rocker arm 207 and the adjusting plate 201, avoiding shaking during the pressing process, and improving the pressing accuracy.

[0028] See Figure 2 , Figure 3 and Figure 4 The rear side wall of the processing plate 1 is provided with a pushing structure 4, which includes a cylinder 401. The output end of the cylinder 401 slides through the U-shaped plate 301 and is connected to the U-shaped push plate 402. The two sides of the U-shaped push plate 402 are rotatably connected to a Z-shaped shaft 403. One end of the Z-shaped shaft 403 is fixedly connected to the side wall of the processing plate 1. The two sides of the U-shaped plate 301 are provided with irregular grooves 404. The other end of the Z-shaped shaft 403 is slidably connected to the irregular grooves 404.

[0029] It is worth noting that when the cylinder 401 is working, its output end pushes the U-shaped push plate 402 to slide within the U-shaped plate 301. During the sliding process, the U-shaped push plate 402 achieves a stable sliding guide effect through the cooperation of the Z-shaped shaft 403 and the irregular groove 404. The Z-shaped shaft 403 is pressed into the front end of the irregular groove 404, pushing the processing plate 1 to rotate and move. The entire assembly process does not need to be carried out inside the pressure structure 3, making the operation convenient and preventing the hydraulic cylinder 304 from pressing down and causing danger, thus ensuring safety. After the motor core is pressed, the cylinder 401 pushes the U-shaped push plate 402 forward, and the U-shaped push plate 402 pushes the processed motor core out of the processing plate 1 for easy collection and processing later.

[0030] See Figure 3 The bottom of the processing plate 1 is provided with two reinforcing frames 405. The rear side wall of the reinforcing frame 405 is fixedly connected to the U-shaped plate 301. The bottom of the U-shaped push plate 402 is provided with a notch 406. The reinforcing frames 405 reinforce the support of the processing plate 1, ensure normal forming support, and also support the stable horizontal movement of the processing plate 1.

[0031] The working principle of manual assembly of motor iron chips is as follows: First, the L-shaped swing arm 207 is swung by hand. The L-shaped swing arm 207 drives the circular plate 206 to move in a circle. During the rotation of the circular plate 206, the fan plate 208 moves in a circle, pressing against the arc-shaped block 2010. This pressing action pushes the adjusting plate 201 to slide horizontally within the sliding cavity 203, thereby synchronously adjusting the movement of the three adjusting plates 201 and changing the distance between them to meet the limiting and clamping requirements of the motor iron chip. Before the pressing process, the limiting structure 5 plays a stabilizing role. When the L-shaped swing arm 207 swings, the sleeve 502 slides at the vertical end of the L-shaped swing arm 207. Due to the tension of the tension spring 504, the sleeve 502 always tends to move towards the processing plate 1. When the sleeve 502 moves to the position of the arc cavity 501, the protrusion 503 is squeezed by the inner wall of the arc cavity 501 and slides along the trajectory of the arc cavity 501 until it is stuck in the slot 505, thereby achieving the limiting function, avoiding shaking during the pressing process, and improving the pressing accuracy.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
