Description

Technical Field

[0001] This utility model relates to the field of motor magnetic sheet processing technology, and in particular to a processing and positioning device for motor magnetic sheets. Background Technology

[0002] As one of the core components of a motor, the machining accuracy of the motor magnetic sheet directly affects the motor's performance and service life. In the machining process of the motor magnetic sheet, accurate positioning is an important auxiliary condition for machining quality. High-precision positioning can effectively reduce errors in the machining process, avoid material waste caused by positioning deviation, and improve the surface smoothness and edge integrity of the magnetic sheet.

[0003] Application No. 201921451584.9 discloses a processing and positioning device for magnetic sheets in electric vehicle motors, including a base plate. From left to right, a first fixing plate and a second fixing plate are fixedly connected to the top of the base plate. A fixing block is movably connected to the top of the base plate, and a magnetic block to be processed is movably connected to the top of the fixing block. This utility model relates to the field of motor processing technology. This processing and positioning device for magnetic sheets in electric vehicle motors, by rotating the first fastening bolt, makes the surface of the fixing groove fit against the surface of the magnetic block to be processed, and fixes the fixing block to prevent slippage. By rotating the second fastening bolt, a pressing block is driven to fix the right side of the magnetic block to be processed. Fixing the magnetic block to be processed on both sides simultaneously ensures that the magnetic blocks are on the same horizontal line, guaranteeing processing accuracy. Furthermore, it can fix magnetic blocks of different sizes, increasing the practicality of the positioning device.

[0004] The above solution has shortcomings in use. The dimensions of the fixing groove and the extrusion groove are fixed. When fixing magnetic sheets of various sizes and specifications, it is impossible to stabilize the magnetic sheets of various sizes and specifications, thus limiting the practicality of the equipment under diversified production needs. Therefore, we provide a processing and positioning device for motor magnetic sheets. Utility Model Content

[0011] Preferably, each of the threaded rods has multiple sets of symmetrically arranged limiting rings fixedly connected to its outer surface.

[0012] Preferably, the adjustable clamping assembly further includes multiple sets of symmetrically arranged arc-shaped grooves on the upper surface of each carrier plate, with a support column slidably connected to the inner wall of each arc-shaped groove, and the top end of each support column connected to the bottom surface of the clamping plate.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] First Embodiment

[0032] As attached Figure 1 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 With appendix Figure 6 As shown: A processing and positioning device for motor magnetic sheets includes a set of carrier plates 1; an adjustable clamping assembly 2 is disposed above the set of carrier plates 1, including a rotating shaft 201 rotatably connected to the upper surface of each carrier plate 1, a clamping plate 202 disposed at the top of each rotating shaft 201, and an adjustment structure disposed above the set of carrier plates 1 for adjusting the opening and closing angle of the clamping plate 202 to suit magnetic sheets of different sizes. The adjustable clamping assembly 2 includes a motor 203 mounted on the upper surface of each carrier plate 1, and each output end of the motor 203 is equipped with a threaded rod 204 with multiple sets of symmetrical threads on its outer surface. The outer surface of the threaded rod 204 is threaded with multiple sets of moving blocks 205. Each moving block 205 is fixedly connected to a push plate 206 on one side near the clamping plate 202. When the motor 203 is started, the threaded rod 204 will rotate. At the same time, the corresponding moving blocks 205 on the threaded rod 204 will move closer to each other. The moving blocks 205 will drive the push plate 206 to move. The push plate 206 will push one end of the clamping plate 202 closer to each other. The clamping plate 202 will then gradually unfold around the rotating shaft 201, thereby adjusting the distance between the clamping plates 202. This allows magnetic sheets of different sizes to be placed between the clamping plates 202.

[0033] Each of the moving blocks 205 has a guide block 207 fixedly connected to its other side. Each set of guide blocks 207 is slidably connected to a guide frame 208. The bottom surface of each guide frame 208 is connected to the upper surface of the carrier plate 1. By cooperating with the guide frame 208 and the guide block 207, the moving block 205 can be stabilized, ensuring that the moving block 205 drives the push plate 206 to slide smoothly. Each of the threaded rods 204 has multiple sets of symmetrically arranged limiting rings 209 fixedly connected to its outer surface. The limiting rings 209 can limit the movement distance of the moving block 205 to prevent the moving block 205 from disengaging from the corresponding thread on the threaded rod 204.

[0034] The adjustable clamping assembly 2 also includes multiple sets of symmetrically arranged arc-shaped grooves 210 on the upper surface of each carrier plate 1. Each arc-shaped groove 210 has a support column 211 slidably connected to its inner wall. The top of each support column 211 is connected to the bottom surface of the clamping plate 202. The cooperation between the support column 211 and the arc-shaped groove 210 not only provides stable support for the other end of the clamping plate 202, but also further constrains and guides the movement of the clamping plate 202, ensuring that the clamping plate 202 moves along a predetermined trajectory during opening and closing, avoiding swaying or deviation. Each set of clamping plates 202 has a spring 212 fixedly connected to one side that is close to each other. When the clamping plates 202 are close to each other, they will compress the spring 212. At the same time, the spring 212 will also apply a reaction force to the clamping plate 202, ensuring close contact between the clamping plate 202 and the push plate 206, further enhancing the stability of the clamping plate 202.

[0035] Second Embodiment

[0036] As attached Figure 1 With appendix Figure 7 As shown: The extrusion assembly 3 is disposed below a set of carrier plates 1 and is used to pull the clamping plates 202 closer together to form a clamping and positioning of the magnetic sheet. The extrusion assembly 3 includes an L-shaped plate 301 fixedly connected to the bottom surface of one of the carrier plates 1. A set of electric push rods 302 are installed on one side of the L-shaped plate 301. The telescopic end of each electric push rod 302 is connected to the bottom surface of the other carrier plate 1. Controlling the retraction of the electric push rod 302 will cause one carrier plate 1 to drive the clamping plate 202 above it to move towards the other clamping plate 202. As the plates approach, the clamps 202 push the magnetic sheet to move, and the four corners of the magnetic sheet gradually come into contact with the four clamps 202, thus forming a clamping and positioning of the magnetic sheet. This method is applicable to the positioning of magnetic sheets of various sizes, improving its practicality under diverse production needs. A set of support wheels 303 is provided above the L-shaped plate 301. The top of each support wheel 303 is connected to the bottom surface of another carrier plate 1. The support wheels 303 can support the moving carrier plate 1 to ensure that it is in a stable state when moving.

[0037] A U-shaped plate 304 is fixedly connected to the upper surface of the L-shaped plate 301. The U-shaped plate 304 is located between the two carrier plates 1, and the upper surface of the U-shaped plate 304 is flush with the upper surface of the carrier plate 1. The U-shaped plate 304 can support the magnetic sheet to prevent it from falling off after detaching from one of the carrier plates 1.

[0038] Third Embodiment

[0039] As attached Figure 1 With appendix Figure 2 As shown: One of the two carrier plates 1 has a set of sliding grooves 4 on its right side. Each sliding groove 4 has a sliding plate 5 slidably connected to its inner wall. The right end of each sliding plate 5 is connected to the left side of the other carrier plate 1. By using the cooperation of the sliding grooves 4 and the sliding plates 5, the two carrier plates 1 can be stabilized, ensuring that the carrier plates 1 can only move in a straight line along a preset direction. This precise guiding effect avoids the carrier plates 1 from deviating or shaking during movement, making the movement of the carrier plates 1 more stable and accurate.

[0040] Working principle: When in use, first adjust the opening angle of the clamping plate 202 according to the size of the magnetic sheet, then start the motor 203 to work, the threaded rod 204 will rotate, and at the same time, the corresponding moving blocks 205 on the threaded rod 204 will move closer to each other. The moving blocks 205 will drive the push plate 206 to move, and the push plate 206 will push one end of the clamping plate 202 to move closer to each other. The clamping plate 202 will then gradually unfold around the rotating shaft 201. Next, place the magnetic sheet on the two carrier plates 1 and position it between the corresponding clamping plates 202. Finally, control the electric push rod 302 to retract, one of the carrier plates 1 will drive the clamping plate 202 above it to move closer to the other clamping plate 202, and the clamping plate 202 will push the magnetic sheet to move. The four corners of the magnetic sheet will gradually contact the four clamping plates 202, thereby forming a clamping and positioning of the magnetic sheet. It can be used for positioning magnetic sheets of various sizes, improving its practicality under diverse production needs.
