Description

Technical Field

[0001] This application relates to the field of magnetizing clamps, and more specifically, to a magnetizing clamp that prevents magnetic tiles from falling off at the corners. Background Technology

[0002] Motor magnets are important components used in motors. In DC motors, motor magnets provide a constant magnetomotive force source for the motor. During the production of motor magnets, magnetization is required. In the existing technology, the loading fixture used for magnetization is generally a rectangular groove structure that matches the specifications of the magnet. The magnets are stacked in the groove and then sent into the magnetizer for magnetization. Although the structure is simple, it requires careful operation by the operator during the magnetization process due to the lack of a clamping mechanism. Otherwise, the stacked magnets are easy to fall off. At the same time, its versatility is poor. Different fixtures need to be prepared for a single reel of magnets of different specifications.

[0003] Chinese patent application CN202220820981.4 discloses a magnetizing clamp for motor magnets. The clamping operation on both sides of the magnet is achieved through the cooperation of a rectangular frame and a movable clamping plate. The movable clamping plate can be adjusted according to the specifications of the magnets to accommodate different sizes. The rectangular frame and the top pressure plate cooperate to clamp the magnets in the longitudinal direction, ensuring stable loading of the magnets within the rectangular frame and preventing them from falling off during magnetization. The magnets can be quickly released from the rectangular frame by lifting the handle and simultaneously closing the control lever. The operation is convenient, fast, and easy to use.

[0004] The above solution also has the following shortcomings: When multiple magnetic tiles are bonded together, due to the brittleness and easy damage to the edges of the magnetic tiles, corners are prone to breakage during the magnetization process, which reduces the processing quality and the practicality of the device. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a magnetizing clamp to prevent corner chipping of magnetic tiles. It aims to improve the problem that when multiple magnetic tiles are bonded together, corner chipping is likely to occur during the magnetizing process due to the brittleness and easily damaged edges of the magnetic tiles, thereby reducing the processing quality and the practicality of the device.

[0006] This application provides a magnetizing clamp to prevent magnetic tiles from chipping, comprising a placement structure and a limiting structure. The placement structure includes a placement frame, two support plates, a placement groove, and a rubber pad. The two support plates are disposed opposite each other within the placement frame. The support plates are evenly provided with a plurality of placement grooves. The rubber pad is fixedly connected to the inner wall of each placement groove. The limiting structure includes a drive assembly, a gear, two toothed plates, a sliding plate, and an L-shaped limiting plate. The drive assembly is disposed within the placement frame. The gear is connected to the drive assembly. Two toothed plates mesh opposite each other on both sides of the gear. The sliding plate is fixedly connected to one side of each toothed plate. The sliding plate is slidably connected to the placement frame. The L-shaped limiting plate is fixedly connected to the sliding plate and fits against the placement frame.

[0007] In one specific implementation, the drive assembly includes a bidirectional lead screw and two lead screw nut pairs. The bidirectional lead screw is rotatably connected to the placement frame, and both lead screw nut pairs are threadedly connected to the bidirectional lead screw. The gear is fixedly connected to the outer ring of the bidirectional lead screw.

[0008] In the above implementation process, the two-way lead screw and the two lead screw nut pairs can be set to easily drive the two L-shaped limit plates to move, so that the L-shaped limit plates fit with the top of the magnetic tile after being limited.

[0009] In one specific implementation, a limiting rod is provided inside the placement frame, and the lead screw and nut pair are slidably connected to the limiting rod.

[0010] In the above implementation process, the movement of the lead screw and nut pair can be conveniently limited by the sliding connection between the lead screw and nut pair and the limiting rod.

[0011] In one specific implementation, a handwheel is fixedly connected to one end of the bidirectional lead screw.

[0012] In the above implementation process, by fixing a handwheel to one end of the bidirectional lead screw, the user can easily rotate the bidirectional lead screw, saving time and effort.

[0013] In one specific implementation, a pushing assembly is provided on one side of the lead screw and nut pair. The pushing assembly includes two connecting blocks, rollers, two inclined platforms, and a top plate. The two connecting blocks are disposed opposite to each other on one side of the lead screw and nut pair. The rollers are rotatably connected to the connecting blocks. The two inclined platforms are disposed opposite to each other on one side of the top plate. The rollers are in contact with the inclined platforms. The top plate is slidably connected to the placement frame.

[0014] In the above implementation process, the setting of two connecting blocks, rollers, two inclined platforms and top plate can facilitate the ejection of the magnetized magnetic tile and facilitate material unloading.

[0015] In one specific implementation, several springs are provided on both sides of the top plate, and the springs are fixedly connected to the inner wall of the placement frame.

[0016] In the above implementation process, the top plate can be easily reset by the setting of the spring.

[0017] In one specific implementation, two limiting frames are arranged opposite each other on the inner wall of the placement frame, and the slide plate is slidably connected to the limiting frames.

[0018] In the above implementation process, the sliding connection between the skateboard and the limiting frame makes it easy to limit the movement of the skateboard.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: the placement frame, two support plates, placement groove and rubber pad can be set to protect the tiles and prevent corners from falling off during magnetization; the drive component, gears, two toothed plates and sliding plate can be set to drive the L-shaped limiting plate to limit the top of the magnetic tile; the pusher component can be set to push out the magnetized magnetic tile and facilitate unloading.

Detailed Implementation

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0024] Please see Figure 1 This application provides a magnetizing clamp to prevent magnetic tiles from falling off at the corners, including a placement structure 10 and a limiting structure 20.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The placement structure 10 includes a placement frame 110, two support plates 120, a placement groove 130, and a rubber pad 140. The two support plates 120 are arranged opposite each other in the placement frame 110. The support plates 120 are evenly provided with a number of placement grooves 130. The rubber pad 140 is fixedly connected to the inner wall of the placement groove 130. The magnetic tile is in contact with the inner wall of the rubber pad 140. The top of the magnetic tile is flush with the top of the rubber pad 140 and the top of the placement frame 110.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting structure 20 includes a drive assembly 210, a gear 220, two toothed plates 230, a slide plate 240, and an L-shaped limiting plate 250. The drive assembly 210 is disposed inside the placement frame 110. The gear 220 is connected to the drive assembly 210. Two toothed plates 230 mesh with each other on both sides of the gear 220. A slide plate 240 is fixedly connected to one side of each toothed plate 230. The slide plate 240 is slidably connected to the placement frame 110. The L-shaped limiting plate 250 is fixedly connected to the slide plate 240. The L-shaped limiting plate 250 is attached to the placement frame 110 and to the top of the magnetic tile.

[0027] In a specific configuration, the drive assembly 210 includes a bidirectional lead screw 211 and two lead screw nut pairs 212. The bidirectional lead screw 211 is rotatably connected to the placement frame 110, and the two lead screw nut pairs 212 are threadedly connected to the bidirectional lead screw 211. The gear 220 is fixedly connected to the outer ring of the bidirectional lead screw 211. The bidirectional lead screw 211 and the two lead screw nut pairs 212 facilitate the movement of the two L-shaped limit plates 250, allowing the L-shaped limit plates 250 to fit against the top of the magnetic tile after being limited.

[0028] In a specific setting, a limit rod 150 is provided inside the placement frame 110, and the lead screw nut pair 212 is slidably connected to the limit rod 150. The slidable connection between the lead screw nut pair 212 and the limit rod 150 facilitates the limitation of the movement of the lead screw nut pair 212.

[0029] In specific settings, a handwheel is fixedly connected to one end of the bidirectional lead screw 211. By fixing the handwheel to one end of the bidirectional lead screw 211, the user can easily rotate the bidirectional lead screw 211, saving time and effort.

[0030] In the specific configuration, a pusher assembly 260 is provided on one side of the lead screw nut pair 212. The pusher assembly 260 includes two connecting blocks 261, rollers 262, two inclined platforms 263, and a top plate 264. The two connecting blocks 261 are positioned opposite each other on one side of the lead screw nut pair 212. The rollers 262 are rotatably connected to the connecting blocks 261. The two inclined platforms 263 are positioned opposite each other on one side of the top plate 264. The rollers 262 are in contact with the inclined platforms 263. The top plate 264 is slidably connected to the placement frame 110. The configuration of the two connecting blocks 261, rollers 262, two inclined platforms 263, and top plate 264 facilitates the ejection of the magnetized magnetic tiles, making material unloading easier.

[0031] In the specific setup, several springs 270 are provided on both sides of the top plate 264. The springs 270 are fixedly connected to the inner wall of the placement frame 110. The setting of the springs 270 makes it easy for the top plate 264 to reset.

[0032] In the specific setup, two limiting frames 160 are set opposite each other on the inner wall of the placement frame 110. The slide plate 240 is slidably connected to the limiting frames 160. The sliding connection between the slide plate 240 and the limiting frames 160 can conveniently limit the movement of the slide plate 240.

[0033] The working principle of this magnetizing clamp to prevent magnetic tiles from falling off is as follows: When using the magnetizing clamp, the magnetic tiles to be magnetized are placed one by one into the placement groove 130. The sides of the magnetic tiles are tightly fitted with the rubber pads 140, and the top is flush with the top surface of the placement frame 110. Turning the handwheel drives the bidirectional lead screw 211 to rotate, which drives the two lead screw nut pairs 212 to move in opposite directions. This synchronously pushes the toothed plates 230 meshing on both sides of the gear 220 to slide laterally, causing the slide plate 240 to move along the guide trajectory of the limiting frame 160. Finally, the two sets of L-shaped limiting plates 250 move synchronously towards the magnet. The top of the tile moves and is pressed, and the double protection of the rubber pad 140 elastic buffer and the L-shaped limiting plate 250 prevents the magnetic tile from falling off. After the clamp is placed in the magnetizer and magnetization is completed, the handwheel is turned in the opposite direction to release the constraint of the L-shaped limiting plate 250. During the movement of the screw nut pair 212, it rolls along the inclined platform 263 through the roller 262, pushing the top plate 264 to rise vertically a distance, pushing the magnetized magnetic tile out of the placement slot 130, making it convenient for the user to take out the magnetized magnetic tile and for unloading. The spring 270 provides a reverse rebound force when the top plate 264 is reset.

[0034] It should be noted that the specific model and specifications of the rubber pad 140 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0035] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
