Description

Technical Field

[0001] This utility model relates to the field of electro-permanent magnet chuck technology, specifically an electro-permanent magnet chuck with a rounding function. Background Technology

[0002] An electro-permanent magnet chuck relies on a permanent magnet to generate attraction. An excitation coil controls the attraction force of the magnet, thus acting as a force switch.

[0003] When current passes through an electro-permanent magnet chuck, the internal magnetic track changes, the magnetism is lost, and the chuck generates a strong magnetic field that can firmly attract metal workpieces. After the current is cut off, the internal magnetic track is restored, the chuck loses its magnetism, and the workpiece can be released. In the existing technology, the electro-permanent magnet chuck is fixed in position on a steel shell. When it is necessary to attract circular workpieces of different sizes, when attracting larger circular workpieces, the force on the chuck is relatively small when it is located at the center of the circle, which is not conducive to the stable attraction of circular workpieces. Therefore, we propose an electro-permanent magnet chuck with a roundness correction function. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electro-permanent magnet chuck with a rounding function. This solves the problem that when the electro-permanent magnet chuck is fixed in position on a steel shell, it is difficult to attract and hold circular workpieces of different sizes. When attracting larger circular workpieces, the electro-permanent magnet chuck is located at the center of the circle, resulting in less force and hindering the stable attraction of the circular workpiece.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electro-permanent magnet chuck with a rounding function, comprising a steel shell and electro-permanent magnet chucks, wherein the electro-permanent magnet chucks are evenly distributed below the steel shell, and includes a connecting unit and a transmission unit. The connecting unit is slidably connected to the steel shell and connected to the corresponding electro-permanent magnet chuck. The transmission unit is located between the connecting unit and the steel shell.

[0006] The connecting unit includes a first sliding seat and a second sliding seat, the second sliding seat being disposed corresponding to the first sliding seat, the first sliding seat and the second sliding seat being slidably connected to the inner wall of the steel shell, and the first sliding seat being fixedly connected to the electro-permanent magnet chuck.

[0007] The transmission unit includes an adjusting seat and a rotating rod. The adjusting seat is slidably connected to the inner wall of the steel housing, and the rotating rod is rotatably connected to the adjusting seat. The other end of the rotating rod is rotatably connected to a second sliding seat.

[0008] Preferably, a connecting seat is fixedly connected to the top end face of the second sliding seat, and the connecting seat is slidably connected to the first sliding seat.

[0009] Preferably, the top end face of the first sliding seat is threaded with a pressing block, which is slidably connected to the inner wall of the connecting seat.

[0010] Preferably, the top end face of the second sliding seat is rotatably connected to the two corresponding rotating rods, and the other end of the two rotating rods is rotatably connected to the adjacent adjusting seat.

[0011] Preferably, the adjustment seats are evenly distributed on the steel shell.

[0012] Preferably, a nut seat is fixedly connected to the bottom end face of the adjusting seat, and the nut seat is slidably connected to the inner wall of the steel shell.

[0013] Preferably, a lead screw is threaded onto the inner wall of the nut seat, and the lead screw is rotatably connected to the inner wall of the steel housing.

[0014] This utility model discloses an electro-permanent magnet chuck with a rounding function, which has the following beneficial effects:

[0015] This electro-permanent magnet chuck with a rounding function moves its adjusting base, which in turn drives a rotating rod to rotate. The rotation of the rotating rod pushes a second sliding base to slide on the inner wall of the steel casing, causing the rotating rod connected to the top end face of the second sliding base to rotate as well. This rotation of the rotating rod pushes the adjusting base to move, ensuring that multiple adjusting bases move along the same path, and consequently, that the second sliding bases slide along the same path. This ensures that multiple electro-permanent magnet chucks can be adjusted simultaneously and consistently. Adjustments are made for circular workpieces of different sizes, ensuring that the electro-permanent magnet chucks are evenly spaced at the edges of the circular workpieces, resulting in more stable adsorption.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This application provides an electro-permanent magnetic chuck with a roundness adjustment function. This solves the problem that when the electro-permanent magnetic chuck 2 is fixed on the steel shell 1, and needs to adsorb circular workpieces of different sizes, the force on the larger circular workpiece is too small when the chuck 2 is at the center of the circle, which is not conducive to stable adsorption. The solution involves moving the adjusting seat 401, which drives the rotating rod 402 to rotate. The rotation of the rotating rod 402 pushes the second sliding seat 302 to slide on the inner wall of the steel shell 1, causing the rotating rod 402, which is rotatably connected to the top end face of the second sliding seat 302, to rotate accordingly. The rotation of the rotating rod 402 pushes the adjusting seat 401 to move, ensuring that multiple adjusting seats 401 move along the same path, and thus the sliding path of the second sliding seat 302 is the same. This ensures that multiple electro-permanent magnetic chucks 2 can be adjusted simultaneously and consistently, corresponding to different sizes of circular workpieces. This allows the electro-permanent magnetic chucks 2 to be evenly spaced at the edges of the circular workpieces, resulting in more stable adsorption.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] This utility model discloses an electro-permanent magnet chuck with a rounding function.

[0027] According to the appendix Figure 1-5As shown, the device includes a steel housing 1 and electro-permanent magnet chucks 2, which are evenly distributed below the steel housing 1. It also includes a connecting unit 3 and a transmission unit 4. The connecting unit 3 is slidably connected to the steel housing 1 and connected to the corresponding electro-permanent magnet chuck 2. The transmission unit 4 is located between the connecting unit 3 and the steel housing 1.

[0028] The connecting unit 3 includes a first sliding seat 301 and a second sliding seat 302. The second sliding seat 302 is set corresponding to the first sliding seat 301. The first sliding seat 301 and the second sliding seat 302 are slidably connected to the inner wall of the steel shell 1. The first sliding seat 301 is fixedly connected to the electro-permanent magnet chuck 2. Pulling the first sliding seat 301 causes the electro-permanent magnet chuck 2 to slide on the steel shell 1. At the same time, the first sliding seat 301 moves relative to the second sliding seat 302, thereby adjusting the movement of the electro-permanent magnet chuck 2 to correspond to the movement of the other electro-permanent magnet chucks 2, so as to meet different magnetic attraction requirements and adjust for round workpieces of different sizes.

[0029] The transmission unit 4 includes an adjusting seat 401 and a rotating rod 402. The adjusting seat 401 is slidably connected to the inner wall of the steel shell 1, and the rotating rod 402 is rotatably connected to the adjusting seat 401. The other end of the rotating rod 402 is rotatably connected to the second sliding seat 302. When the adjusting seat 401 is moved, the adjusting seat 401 drives the rotating rod 402 to rotate. Under the rotation of the rotating rod 402, the second sliding seat 302 is pushed to slide on the inner wall of the steel shell 1, so that the rotating rod 402, which is rotatably connected to the top end face of the second sliding seat 302, rotates accordingly. Under the rotation of the rotating rod 402, the adjusting seat 401 is pushed to move, so that the multiple adjusting seats 401 move along the same path, and thus the sliding path of the second sliding seat 302 is the same, ensuring that multiple electro-permanent magnet chucks 2 are adjusted simultaneously, ensuring consistent adjustment, and adjusting for circular workpieces of different sizes, so that the electro-permanent magnet chucks 2 are evenly spaced at the edge of the circular workpiece, making their adsorption more stable.

[0030] A connecting seat 303 is fixedly connected to the top end face of the second sliding seat 302, and the connecting seat 303 is slidably connected to the first sliding seat 301.

[0031] The top end face of the first sliding seat 301 is threaded with a pressing block. The pressing block is slidably connected to the inner wall of the connecting seat 303. By rotating the pressing block, it separates from the connecting seat 303. At this time, the first sliding seat 301 can be pulled to drive the electro-permanent magnet chuck 2 to slide on the steel shell 1. At the same time, the first sliding seat 301 moves relative to the second sliding seat 302, thereby adjusting the electro-permanent magnet chuck 2 to move in relation to the other electro-permanent magnet chucks 2. This facilitates the handling of different magnetic attraction requirements and allows for adjustment of different sized circular workpieces. The electro-permanent magnet chucks 2 are evenly spaced at the edges of the circular workpieces, making their adsorption more stable.

[0032] When the electro-permanent magnet chuck 2 is adjusted to a suitable position, the pressing block is rotated to make it contact the outer wall of the connecting seat 303, pressing the connecting seat 303 onto the first sliding seat 301, thus completing the relative fixation of the first sliding seat 301, the second sliding seat 302 and the connecting seat 303.

[0033] The top end face of the second sliding seat 302 is rotatably connected to the two corresponding rotating rods 402. The other ends of the two rotating rods 402 are rotatably connected to the adjacent adjusting seat 401. When one of the adjusting seats 401 is adjusted to move, the adjusting seat 401 drives the rotating rod 402 to rotate. Under the rotation of the rotating rod 402, the second sliding seat 302 is pushed to slide on the inner wall of the steel shell 1.

[0034] At this time, the movement of the second sliding seat 302 causes the rotating rod 402, which is rotatably connected to the top end face of the second sliding seat 302, to rotate. The rotation of the rotating rod 402 pushes the adjusting seat 401 to move.

[0035] The adjusting seats 401 are evenly distributed on the steel shell 1. When the second sliding seat 302 moves, it drives the rotating rod 402 to rotate, which in turn drives the adjusting seats 401 to move. Since the rotating rod 402 rotates at the same angle, the multiple adjusting seats 401 move along the same path, which in turn makes the sliding path of the second sliding seat 302 the same, ensuring that multiple electro-permanent magnet chucks 2 are adjusted simultaneously and that the adjustment is consistent.

[0036] A nut seat 403 is fixedly connected to the bottom end face of the adjusting seat 401. The nut seat 403 is slidably connected to the inner wall of the steel shell 1. Under the constraint of the nut seat 403, the sliding of the adjusting seat 401 on the steel shell 1 is relatively stable.

[0037] A lead screw 404 is threaded onto the inner wall of the nut seat 403. The lead screw 404 is rotatably connected to the inner wall of the steel housing 1. By rotating the lead screw 404, the nut seat 403 is driven to slide on the inner wall of the steel housing 1, thereby causing the nut seat 403 to move the corresponding adjusting seat 401.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
