Description

Technical Field

[0001] This utility model relates to the field of CNC roll grinding machine technology, and more specifically, to an electromagnetic clamping device for a low-wear CNC roll grinding machine. Background Technology

[0002] A CNC roll grinding machine is a high-precision CNC machine tool specifically designed for processing rolls (core components of rolling mills used for rolling metal sheets, pipes, profiles, etc.). It uses a computer numerical control (CNC) system to precisely control the movement trajectory and grinding parameters of the grinding wheel, achieving high-precision grinding of the roll surface and ensuring that the roll's dimensional accuracy, surface roughness, and geometry meet process requirements.

[0003] A search revealed that Chinese patent CN212122626U discloses a CNC roll grinding machine. The machine involves slowly bringing a rotating grinding wheel close to the outer circumference of the roll until sparks are generated. The grinding wheel then grinds the roll, producing a large amount of metal powder. This powder is then thrown towards a waste collection tray by the centrifugal force of the rotating grinding wheel. The waste collection tray collects the metal powder, preventing it from scattering and improving the cleanliness and usability of the grinding machine.

[0004] When the above-mentioned rolls are used, the rolls are fixedly clamped between the roll chuck and the ejector pin. However, when the chuck is clamped, the contact friction between the chuck and the roll journal will cause surface scratches and fixture wear, resulting in defects on the surface of the rolled sheet, reducing product quality, and making it inconvenient to clamp the rolls with low wear. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electromagnetic clamping device for a low-wear CNC roll grinding machine, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-wear CNC roll grinding machine electromagnetic clamping device, comprising a housing and an electromagnetic clamping assembly, wherein the electromagnetic clamping assembly is mounted on the housing, the electromagnetic clamping assembly comprising an electromagnetic motor, a first connecting plate, a second connecting plate, a first electromagnetic chuck, and a second electromagnetic chuck, the electromagnetic motor being fixedly mounted inside one side of the housing, the first connecting plate being fixedly sleeved on the output end of the electromagnetic motor, and the first connecting plate and the second connecting plate being fixed together by bolts, the first electromagnetic chuck being fixedly mounted inside the second connecting plate, one end of the second electromagnetic chuck extending into the second connecting plate, and the second electromagnetic chuck being threadedly connected to the second connecting plate.

[0007] Furthermore, a fixing plate is fixedly installed on the other side of the outer casing.

[0008] As can be seen, in the above technical solution, the fixing plate is installed on the grinding machine by bolts, thereby fixing the outer shell to the grinding machine.

[0009] Furthermore, the outer casing is provided with a moving component, which includes a self-locking motor, a gear rod, two toothed plates and two L-shaped plates. Two limiting grooves are opened on one side of the outer casing, and one side of each of the two L-shaped plates passes through the two limiting grooves.

[0010] Furthermore, the self-locking motor is fixedly installed inside the housing on the other side, and the output shaft end of the self-locking motor is fixedly connected to the gear rod. The two toothed plates are engaged with the gear rod on opposite sides, and the two toothed plates are fixedly connected to the two L-shaped plates respectively on opposite sides.

[0011] It can be seen that the above technical solution is designed to facilitate the movement of the two extrusion plates towards each other.

[0012] Furthermore, a U-shaped plate is movably connected to the gear rod via a bearing, and one side of the U-shaped plate is fixedly connected to the outer casing.

[0013] It can be seen that the above technical solution is designed to facilitate the support of the gear rod.

[0014] Furthermore, an extrusion assembly is provided between the two L-shaped plates. The extrusion assembly includes an extrusion plate, two lead screws, two baffles, and multiple threaded sleeves, and the number of extrusion assemblies is two.

[0015] Furthermore, the top end of the extrusion plate is fixedly connected to the L-shaped plate, the bottom ends of the two lead screws pass through the extrusion plate and are fixedly connected to the two baffles, and the multiple threaded sleeves are respectively movably sleeved on the two lead screws.

[0016] It can be seen that the above technical solution is designed to facilitate the limiting of the front and rear sides of the roll.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model uses bolts to fix the second connecting plate to the first connecting plate. The roll is placed on one side of the first electromagnetic chuck. The electromagnetic motor works to generate a magnetic field. The magnetic lines of force pass through the first electromagnetic chuck and the roll to form a closed loop, firmly adsorbing the roll onto the surface of the first electromagnetic chuck. The adsorption between the roll and the surface of the first electromagnetic chuck is purely magnetic, without the sliding or friction of mechanical clamping parts. The operation is simple and convenient for low-wear clamping of the roll.

[0019] 2. This utility model uses a self-locking motor to drive two extrusion plates to move towards each other. The two extrusion plates extrude and position the roll, placing it at the center of one side of the first electromagnetic chuck. The two extrusion plates can drive four baffles to move vertically, limiting the front and rear sides of the roll. After positioning, the self-locking motor reverses and drives the two extrusion plates to move away from each other. The operation is simple and convenient for positioning the roll.

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

The electromagnetic clamping assembly 2 includes an electromagnetic motor 201, a first connecting plate 202, a second connecting plate 203, a first electromagnetic chuck 204, and a second electromagnetic chuck 205. The electromagnetic motor 201 is fixedly mounted inside one side of the housing 1. The first connecting plate 202 is fixedly sleeved on the output end of the electromagnetic motor 201, and the first connecting plate 202 and the second connecting plate 203 are fixed together by bolts. The first electromagnetic chuck 204 is fixedly mounted inside the second connecting plate 203. One end of the second electromagnetic chuck 205 extends into the second connecting plate 203, and the second electromagnetic chuck 205 is threadedly connected to the second connecting plate 203.

[0029] Furthermore, a fixing plate 6 is fixedly installed on the other side of the outer casing 1.

[0030] Furthermore, a movable component 4 is provided on the outer casing 1. The movable component 4 includes a self-locking motor 401, a gear rod 402, two toothed plates 403, and two L-shaped plates 404. Two limiting grooves 5 are opened on one side of the outer casing 1, and one side of each of the two L-shaped plates 404 passes through the two limiting grooves 5. The self-locking motor 401 is fixedly installed on the other side inside the outer casing 1, and the output shaft end of the self-locking motor 401 is fixedly connected to the gear rod 402. The opposing sides of the two toothed plates 403 are engaged with the gear rod 402, and the opposing sides of the two toothed plates 403 are fixedly connected to the two L-shaped plates 404. A U-shaped plate 7 is movably connected to the gear rod 402 through a bearing, and one side of the U-shaped plate 7 is fixedly connected to the outer casing 1.

[0031] Furthermore, an extrusion assembly 3 is provided between the two L-shaped plates 404. The extrusion assembly 3 includes an extrusion plate 301, two lead screws 302, two baffles 303, and multiple threaded sleeves 304. There are two extrusion assemblies 3. The top end of the extrusion plate 301 is fixedly connected to the L-shaped plate 404. The bottom ends of the two lead screws 302 pass through the extrusion plate 301 and are fixedly connected to the two baffles 303. The multiple threaded sleeves 304 are respectively movably sleeved on the two lead screws 302.

[0032] The U-shaped plate 7 supports the gear rod 402. When the self-locking motor 401 is activated, it drives the gear rod 402 to rotate. Since both toothed plates 403 mesh with the gear rod 402, and the two L-shaped plates 404 and two limiting grooves 5 cooperate to restrict the deflection of the toothed plates 403, the gear rod 402 can drive the two toothed plates 403 to move towards each other, thereby driving the two L-shaped plates 404 to move towards each other, and further driving the two extrusion plates 301 to move towards each other. The two extrusion plates 301 extrude and position the roll, thus enabling the roll to... The roller is located at the center of one side of the first electromagnetic chuck 204. Rotate the threaded sleeve 304 and move it away from the extrusion plate 301 to release the fixation between the screw 302 and the extrusion plate 301. Move the baffle 303 vertically away from the extrusion plate 301. Similarly, adjust the position of the other baffles 303. The two extrusion plates 301 can drive the four baffles 303 to move vertically. The four baffles 303 limit the front and rear sides of the roller. After positioning is completed, the self-locking motor 401 reverses and drives the two extrusion plates 301 to move in opposite directions. The operation is simple and convenient for positioning the roller.

[0034] In use, the fixing plate 6 is installed on the grinding machine with bolts, thereby fixing the outer casing 1 to the grinding machine. The second connecting plate 203 is attached to the first connecting plate 202 and fixed to the first connecting plate 202 with bolts, thereby fixing the first electromagnetic chuck 204 to the electromagnetic motor 201. The roller is placed on one side of the first electromagnetic chuck 204, and then the electromagnetic motor 201 is started. The electromagnetic motor 201 works and generates a magnetic field. The magnetic lines of force pass through the first electromagnetic chuck 204 and the roller to form a closed loop. The roll is firmly attached to the surface of the first electromagnetic chuck 204. Similarly, when the electromagnetic motor 201 is turned off, the magnetic field disappears, and the roll can be easily disassembled. The roll and the surface of the first electromagnetic chuck 204 are attached by pure magnetic force, without the sliding or friction of mechanical clamping parts. The operation is simple and convenient for low-wear clamping of the roll. The second electromagnetic chuck 205 is rotated and extended into the second connecting plate 203. Similarly, other second electromagnetic chucks 205 are installed to attach to different parts of the roll, so that the roll is subjected to a more uniform suction force.
