[0002] End plates are common, key structural components in mechanical transmission systems, hydraulic systems, and fluid equipment. They are widely used in motor housings, hydraulic cylinders, pump and valve assemblies, and other fields. Because end plates must precisely mate with other components, their machining accuracy directly impacts the overall performance of the equipment. Therefore, machining end plates places high demands on positioning accuracy, clamping stability, and processing efficiency.

The special-shaped groove is used to clamp different workpieces. The hydraulic clamp is provided with a special-shaped groove on the side wall of the clamping member. The special-shaped groove is mainly a notch that combines a circle and a square. The special-shaped groove can simultaneously clamp round or square table legs, avoiding the need to repeatedly replace clamps of different shapes.

At the same time, the driving motor can drive the rotating rod to rotate, and the rotating rod can drive the clamping member and the table leg to rotate, facilitating comprehensive polishing of the table leg surface.

[0004] The hydraulic clamp for machining the end plate mentioned above fails to take into account the influence of the centering of the workpiece. If traditional clamping is used, due to inconsistent clamping force, frequency synchronization of the equipment and other issues, poor centering may occur during clamping, resulting in insufficient centering accuracy of the workpiece, leading to dimensional deviation after processing and affecting the use of the product.

[0015] The present invention provides a hydraulic clamp for machining end plates. It has the following beneficial effects:

[0016] (1) The present invention sets a centering device so that when the cylinder pushes the push plate to move forward, the push plate drives the extrusion block to move the L rod forward, and the L rod drives one end of the connecting rod to move forward, and the other end drives the connecting slide rod to slide, and the connecting slide rod pulls another set of devices, thereby ensuring that the workpiece is in the center position, solving the problem of insufficient cylinder synchronization causing the workpiece to deviate from the center position, thereby ensuring uniform workpiece processing specifications.

[0017] (2) The present invention sets a knocking device. When the push piece moves, the clamping piece moves by pushing the spring. When the clamping piece contacts the workpiece, the clamping piece is brought close to the push piece, so that the friction table rubs against the rubber roller. The rubber roller rotates and drives the slider to rotate the knocking block through the short rod to knock the workpiece, knocking off the slag remaining after cutting, solving the problem that the slag remaining on the workpiece affects the subsequent processing and improving the processing quality.

[0018] (3) The present invention provides a cooling device. When the friction table is driven by the push plate, the push plate moves the extrusion plate forward through the L block, causing the extrusion plate to slide in the air chamber, and the gas in the air chamber is ejected from the air nozzle through the air pipe, so that the air nozzle sprays air toward the workpiece, making the temperature of the workpiece closer to the environment, solving the problem of thermal deformation caused by the residual heat of the workpiece after cutting under clamping, and improving the processing accuracy of the workpiece.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1-6 One embodiment of the present invention is a hydraulic fixture for machining an end plate, comprising a platform 1, the upper side of the platform 1 being fixedly connected to the lower end of a cylinder 2, the output end of the cylinder 2 being fixedly connected to the inner wall of a push plate 3, and a centering device 4 being provided on the upper side of the platform 1 for ensuring that the workpiece is centered;

[0028] Among them, the centering device 4 includes a horizontal slide groove 401, a vertical slide groove 402, an L rod 403, an extrusion block 404, a return spring 405, a connecting rod 406 and a connecting slide rod 407; a horizontal slide groove 401 is horizontally opened on the platform 1, and a vertical slide groove 402 is vertically opened on the platform 1, so that the horizontal slide groove 401 and the vertical slide groove 402 ensure that the sliding direction of the device is fixed, the inner wall of the vertical slide groove 402 is slidably connected to the outer wall of the L rod 403, the lower end of the push piece 3 is fixedly connected to the upper end of the extrusion block 404, and the rear side of the L rod 403 is fixed to one end of the return spring 405 It is fixedly connected, and the other end of the return spring 405 is fixedly connected to the protrusion on the platform 1, so that when the L rod 403 loses its extrusion, the return spring 405 resets the L rod 403, and the inner wall of the horizontal slide groove 401 is slidingly connected to the outer wall of the connecting slide 407, and the outer wall of the connecting slide 407 is rotatably connected to the inner wall of one end of the connecting rod 406, and the inner wall of the other end of the connecting rod 406 is slidingly connected to the outer wall of the L rod 403, so that when the connecting slide 407 is pushed by the faster cylinder group 2, it reacts to the slower cylinder group 2 to achieve synchronization.

[0029] The present invention provides a centering device 4, so that when the cylinder 2 pushes the push plate 3 to move forward, the push plate 3 drives the extrusion block 404 to move the L rod 403 forward, and the L rod 403 drives one end of the connecting rod 406 to move forward, and the other end drives the connecting slide 407 to slide, and the connecting slide 407 pulls another set of devices, thereby ensuring that the workpiece is in the center position, solving the problem of insufficient synchronization of the cylinder 2 causing the workpiece to deviate from the center position, thereby ensuring uniform workpiece processing specifications.

[0030] When this embodiment works: after the workpiece is placed on the platform 1, the cylinder 2 is started. When the cylinder 2 is started, the cylinder 2 pushes the push piece 3 to move forward. When the push piece 3 moves forward, the push piece 3 drives the extrusion block 404 to move forward synchronously. When the extrusion block 404 moves forward, the extrusion block 404 is stuck in the groove of the L rod 403. When the extrusion block 404 is stuck in the groove of the L rod 403, the extrusion block 404 pushes the L rod 403 to slide forward. When the L rod 403 slides forward, if the cylinders 2 are not completely synchronized, one of the cylinders 2 first generates thrust, at this time, pushing the L rod 403 to slide in the vertical slide groove 402 and move forward. When the L rod 403 slides in the vertical slide groove 402 and moves forward, the L rod 403 pulls the return spring 405. When the L rod 403 pulls the return spring 405, the L rod 403 drives one end of the connecting rod 406 to move forward. When one end of the connecting rod 406 moves forward, the other end of the connecting rod 406 squeezes the connecting slide rod 407. When the connecting slide rod 407 is squeezed, it slides outward in the horizontal slide groove 401. When the connecting slide 407 slides in the horizontal slide groove 401, the connecting slide 407 pulls one end of the other group of connecting rods 406 to move. When the connecting slide 407 pulls one end of the other group of connecting rods 406 to move, the other end of the other group of connecting rods 406 pulls the L rod 403 pushed by the slower cylinder 2 to move synchronously to ensure that the workpiece is necessarily centered. On the contrary, the cylinder 2 is closed. When the cylinder 2 is closed, the cylinder 2 pulls the push piece 3 to move backward. When the push piece 3 moves backward, the push piece 3 drives the extrusion block 404 to move backward synchronously. When the extrusion block When 404 moves backward, the squeezing block 404 disengages from the groove of the L rod 403. When the squeezing block 404 disengages from the groove of the L rod 403, the squeezing block 404 no longer squeezes the L rod 403 and slides forward. When the squeezing block 404 no longer squeezes the L rod 403 and slides forward, the return spring 405 pulls the L rod 403 to reset. When the L rod 403 is reset, the L rod 403 pulls one end of the connecting rod 406 to move. When the L rod 403 pulls one end of the connecting rod 406 to move, the other end of the connecting rod 406 pulls the connecting slide rod 407 to reset.

[0031] See also Figures 1-6On the basis of the above embodiment, in another embodiment of the present invention, a knocking device 5 for knocking off the residual slag on the workpiece after cutting is provided on the upper side of the platform 1, and the knocking device 5 includes a limit rod 501, a pushing spring 502, a clamping piece 503, a short rod 504, a rubber roller 505, a friction table 506, a slider 507, an extrusion spring 508 and a knocking block 509. The inner wall of the push piece 3 is slidably connected to the outer wall of the limit rod 501, so that the limit rod 501 ensures the sliding direction of the clamping piece 503, the front end of the limit rod 501 is fixedly connected to the rear end of the clamping piece 503, the front side of the push piece 3 is fixedly connected to one end of the pushing spring 502, and the other end of the pushing spring 502 is fixedly connected to the clamping piece 503. The rear side is fixedly connected, the inner wall of the clamping piece 503 is rotatably connected to the outer wall of the short rod 504, and the outer wall of the short rod 504 is fixedly connected to the inner wall of the rubber roller 505, so that the pushing spring 502 provides a movable distance between the clamping piece 503 and the pushing piece 3, the outer side of the pushing piece 3 is fixedly connected to the inner side of the friction table 506, the lower side of the short rod 504 is fixedly connected to the upper end of the slider 507, the inner wall of the slider 507 is fixedly connected to one end of the extrusion spring 508, and the other end of the extrusion spring 508 is fixedly connected to the inner wall of the striking block 509, and the outer wall of the striking block 509 is slidably connected to the inner wall of the slider 507, so that the friction table 506 is rough and can generate greater friction with the rubber roller 505.

[0032] When the push piece 3 moves, the clamping piece 503 is moved by pushing the spring 502. When the clamping piece 503 contacts the workpiece, the clamping piece 503 is close to the push piece 3, so that the friction table 506 rubs against the rubber roller 505. The rubber roller 505 rotates and drives the slider 507 to drive the striking block 509 to rotate through the short rod 504, knocking the workpiece to knock off the slag remaining after cutting, solving the problem of the slag remaining on the workpiece affecting subsequent processing and improving the processing quality.

[0033] The upper side of the platform 1 is provided with a cooling device 6 to prevent thermal deformation caused by residual heat from cutting during clamping. The cooling device 6 includes an air chamber 601, an L-block 602, an extrusion sheet 603, an air pipe 604 and an air nozzle 605. The upper side of the platform 1 is fixedly connected to the lower side of the air chamber 601, the outer side of the friction table 506 is fixedly connected to the inner side of the L-block 602, the outer side of the L-block 602 is fixedly connected to the inner side of the extrusion sheet 603, and the outer wall of the extrusion sheet 603 is slidably connected to the inner wall of the air chamber 601, the upper side of the air chamber 601 is fixedly connected to the lower side of the air pipe 604, the inner wall of the air pipe 604 is fixedly connected to the outer wall of the air nozzle 605, and the air chamber 601, the air pipe 604 and the air nozzle 605 are internally penetrated.

[0034] The present invention provides a cooling device 6. When the friction table 506 is driven by the push piece 3, the push piece 3 causes the extrusion piece 603 to move forward through the L block 602, so that the extrusion piece 603 slides in the air chamber 601, and the gas in the air chamber 601 is ejected from the air nozzle 605 through the air pipe 604, so that the air nozzle 605 sprays air toward the workpiece, making the temperature of the workpiece closer to the environment, solving the problem of thermal deformation of the workpiece caused by the residual heat after cutting under clamping, and improving the processing accuracy of the workpiece.

[0035] When the push piece 3 moves forward, the push piece 3 drives the pushing spring 502 to move forward. When the pushing spring 502 moves forward, the pushing spring 502 pushes the clamping piece 503 to move forward. When the clamping piece 503 moves forward, the clamping piece 503 contacts the workpiece. When the clamping piece 503 contacts the workpiece, the clamping piece 503 is squeezed and the pushing spring 502 is compressed. When the clamping piece 503 is squeezed and the pushing spring 502 is compressed, the limiting rod 501 slides backward. When the limiting rod 501 slides backward When the push piece 3 drives the friction table 506 to slide forward synchronously, when the push piece 3 drives the friction table 506 to slide forward synchronously, the friction table 506 rubs against the rubber roller 505, and when the friction table 506 rubs against the rubber roller 505, the rubber roller 505 rotates. When the rubber roller 505 rotates, the rubber roller 505 drives the short rod 504 to rotate. When the short rod 504 rotates, the short rod 504 drives the slider 507 to rotate synchronously. When the slider 507 rotates, the slider 507 drives the striking block 509 to rotate synchronously. When the striking block 509 rotates, the striking block 509 collides with the workpiece. When the striking block 509 collides with the workpiece, the striking block 509 is compressed. When the striking block 509 is compressed, the striking block 509 squeezes the squeezing spring 508 to compress it. When the squeezing spring 508 is compressed, the striking block 509 slides into the inner wall of the slider 507. When the striking block 509 rotates to pass over the workpiece, the striking block 509 that loses the squeezing is ejected under the push of the squeezing spring 508, so as to facilitate the next round of knocking, thereby achieving continuous knocking; on the contrary, when the push piece 3 moves to When the clamping piece 503 is no longer in contact with the workpiece, the clamping piece 503 is no longer squeezed. When the clamping piece 503 is no longer squeezed, the pushing spring 502 pushes the clamping piece 503 to reset, causing the limiting rod 501 to slide out synchronously to reset the device.

[0036] When the friction table 506 moves forward, the friction table 506 drives the L block 602 to move forward. When the L block 602 moves forward, the L block 602 drives the extrusion sheet 603 to slide forward. When the extrusion sheet 603 slides forward, the extrusion sheet 603 slides on the inner wall of the air chamber 601. When the extrusion sheet 603 slides on the inner wall of the air chamber 601, the air in the air chamber 601 is squeezed. When the air in the air chamber 601 is squeezed, the air in the air chamber 601 is ejected from the air nozzle 605 through the air pipe 604. When the air is ejected from the air nozzle 605, it is sprayed onto the workpiece to cool it and take away the heat.
