Technical Field

[0001] This utility model relates to the field of machining clamping technology, specifically a clamping device for machining. Background Technology

[0002] Existing clamping devices have a problem during the workpiece clamping process: regardless of whether it is an integrated or separate clamping device, the clamping devices will inevitably collide with each other to some extent during the clamping process. To address this, this device adopts a new structure and principle for clamping, successfully avoiding the damage caused by mutual collisions. Moreover, compared with traditional clamping devices, the device has changed its power source, making the clamping device more adaptable and avoiding the problem of single power source for clamping devices. Therefore, there is a need for a machining clamping device that solves the above problems. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a clamping device for machining, which solves the problems mentioned in the background.

[0004] This utility model provides the following technical solution: a clamping device for machining, comprising: a machining table, a side sealing plate on the outer wall of the machining table, an adjustment hole on the outer wall of the machining table, an mounting plate overlapping the outer wall of the machining table, a cylinder fixedly sleeved on the inner wall of the mounting plate, a piston cylinder installed in the inner cavity of the cylinder, a reserved hole on the outer wall of the cylinder, a piston rod connected to the outer wall of the piston cylinder, a connecting pin connected to the inner wall of the piston rod, a disc first sleeved on the outer wall of the piston rod, a magnetic sheet first sleeved on the inner wall of the disc first, a sliding groove on the inner wall of the machining table, a slider sleeved on the inner wall of the sliding groove, a connecting rod fixedly connected to the outer wall of the slider, a disc second connected to the outer wall of the connecting rod, a magnetic sheet second sleeved on the inner wall of the disc second, a clamp fixedly connected to the outer wall of the connecting rod, and a bottom support plate on the bottom of the machining table.

[0005] Preferably, there are two side sealing plates, and the two side sealing plates are arranged on both sides of the processing table.

[0006] Preferably, the number of adjustment holes is several, and the several adjustment holes are arranged on the outer wall of the processing table.

[0007] Preferably, the connecting pin passes laterally through the inner wall of the first disc and the inner wall of the piston rod, and the connecting pin fixes the piston rod and the first disc in place.

[0008] Preferably, the first magnetic sheet and the second magnetic sheet are arranged on the same horizontal line, and the first magnetic sheet and the second magnetic sheet are the same magnet.

[0009] Preferably, the outer wall of the slider is adapted to the size of the inner wall of the groove, and the slider is connected to the second disk via a connecting rod.

[0010] Preferably, the inner wall of the clamp is arc-shaped, and the two clamps are arranged opposite each other.

[0011] Preferably, the outer wall of the base plate is provided with a workpiece, and the workpiece is cylindrical.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This machining clamping device, by setting up magnetic sheet one, magnetic sheet two, clamping device, and workpiece, etc., when magnetic sheet one approaches magnetic sheet two, the magnetic repulsion property of like magnets causes magnetic sheet two to bring the clamping device closer together. Under the action of the piston cylinder, the distance between magnetic sheet one and magnetic sheet two on both sides will continuously decrease, thereby using the gradually increasing repulsive force to make the clamping devices on both sides tightly clamp the workpiece in the middle, and the clamping devices on both sides clamp the workpiece without colliding with each other.

[0014] 2. This machining clamping device, by setting up a piston cylinder, piston rod, magnetic plate two, and clamping device, ensures that magnetic plate two on the device does not actively push the clamping device closer together to clamp the workpiece. When the piston cylinder controls the piston rod to extend, magnetic plate one pushes magnetic plate two and the clamping device closer to the middle of the device, so that the clamping device on the device forms a clamping posture, thereby changing the original power mode of the clamping device and using hydraulic power as the power source.

[0021] 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.

[0022] Please see Figure 1-5 A clamping device for machining includes: a machining table 1, a side sealing plate 2 on the outer wall of the machining table 1, an adjustment hole 3 on the outer wall of the machining table 1, a mounting plate 4 overlapping the outer wall of the machining table 1, a cylinder 5 fixedly sleeved on the inner wall of the mounting plate 4, a piston cylinder 6 installed in the inner cavity of the cylinder 5, a reserved hole 7 on the outer wall of the cylinder 5, a piston rod 8 connected to the outer wall of the piston cylinder 6, and a connecting pin 9 connected to the inner wall of the piston rod 8. A disc 10 is fitted onto the outer wall of the piston rod 8, and a magnetic sheet 11 is fitted onto the inner wall of the disc 10. A groove 12 is provided on the inner wall of the processing table 1, and a slider 13 is fitted onto the inner wall of the groove 12. A connecting rod 14 is fixedly connected to the outer wall of the slider 13. A disc 15 is connected to the outer wall of the connecting rod 14, and a magnetic sheet 16 is fitted onto the inner wall of the disc 15. A clamp 17 is fixedly connected to the outer wall of the connecting rod 14. A base plate 18 is provided at the bottom of the processing table 1.

[0023] Among them, there are two side sealing plates 2, and the two side sealing plates 2 are set on both sides of the processing table 1. When the slide groove 12 is opened in the inner wall of the processing table 1 on the device, the side sealing plates 2 on both sides of the device fully block the slide, so that the parts sliding in the inner cavity of the slide groove 12 will not fall out of the device.

[0024] The number of adjustment holes 3 is several, and the adjustment holes 3 are arranged on the outer wall of the processing table 1. When the adjustment holes 3 on the device are opened on the outer wall of the processing table 1, when the mounting plate 4 and cylinder 5 on the device need to be changed, the mounting plate 4 is moved along the outer wall of the processing table 1, and the screw is connected to the inner cavity of the adjustment hole 3 through the inner wall of the mounting plate 4, so that the mounting plate 4 is fixed again.

[0025] The connecting pin 9 passes laterally through the inner wall of the disc-10 and the inner wall of the piston rod 8, and the connecting pin 9 fixes the piston rod 8 and the disc-10 together. The piston rod 8 extends through the end of the device into the inner cavity of the disc-10, and the connecting pin 9 passes through the inner cavity of the disc-10, thereby fixing the piston rod 8 and the disc-10 together, and thus causing the piston rod 8 to push the disc-10 forward.

[0026] Among them, magnetic sheet 11 and magnetic sheet 2 16 are set on the same horizontal line, and magnetic sheet 11 and magnetic sheet 2 16 are the same magnet. When magnetic sheet 11 on the device approaches magnetic sheet 2 16 under the drive of disk 10, magnetic sheet 11 and magnetic sheet 2 16 on the device generate a repulsive reaction between like charges, thereby pushing magnetic sheet 2 16 forward.

[0027] The outer wall of slider 13 is adapted to the size of the inner wall of slide groove 12, and slider 13 is connected to disk 15 through connecting rod 14. When magnetic sheet 16 on the device moves forward under the action of magnetic force of the same phase, slider 13 on the device slides along the inner cavity of slide groove 12, so that magnetic sheet 16, disk 15 and slider 13 on the device move synchronously, thereby preventing slider 13 on both sides from leaving the device in the inner cavity of slide groove 12.

[0028] The inner wall of the clamp 17 is set in an arc shape, and the two clamps 17 are arranged opposite each other. When the two clamps 17 on the device are arranged opposite each other, the two clamps 17 on the device move towards the middle under the push of the magnetic plates 16 on both sides, so that the two clamps 17 are close to each other and use the arc-shaped inner wall to clamp the workpiece 19.

[0029] The outer wall of the support plate 18 is provided with a workpiece 19, which is cylindrical. When the workpiece 19 is placed on the top of the support plate 18, the device is in a circular shape, which is the optimal time to use the device. The support plate 18 then supports the workpiece 19 at the bottom of the device.

[0030] The working principle involves setting up structures such as magnetic sheet 11, magnetic sheet 16, clamping device 17, and workpiece 19. When magnetic sheet 11 approaches magnetic sheet 16, the repulsive property of like magnets causes magnetic sheet 16, carrying the clamping device 17, to move closer together. Driven by the piston cylinder 6, the distance between magnetic sheets 11 and 16 on both sides continuously decreases. This gradually increasing repulsive force allows the clamping devices 17 on both sides to tightly clamp the workpiece 19 in the middle, without requiring the clamping devices 17 to collide with each other. In this case, the workpiece 19 is clamped. By setting up structures such as piston cylinder 6, piston rod 8, magnetic sheet 16, and clamping device 17, the magnetic sheet 16 on the device will not actively push the clamping device 17 to move closer to each other and clamp the workpiece 19. When the piston cylinder 6 controls the piston rod 8 to extend, the magnetic sheet 11 will push the magnetic sheet 16 and the clamping device 17 to move closer to the middle of the device, so that the clamping device 17 forms a clamping posture. This changes the original power mode of the clamping device and uses hydraulic power as the power source.

[0031] 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.
