[0052] In order to solve the technical problem in the existing technology that the structure of the automatic hydraulic clamp cannot maintain sufficient stability during long-term operation due to squeezing, which affects the quality of clamping work, please refer to Figure 1 、 Figure 4 - Figure 5 , providing the following technical solutions:

[0053] A first transmission gear 302 is installed at one end of the transmission arm 301, a fixed cylinder is installed inside one end of the first transmission gear 302, and the fixed cylinder is fixedly connected to the first transmission gear 302, and the fixed cylinder is rotatably connected to the shaft sleeve through a bearing, a second transmission gear 303 is installed on one side of the first transmission gear 302, a third transmission gear 304 is installed on one side of the second transmission gear 303, and the second transmission gear 303 is respectively meshed and connected with the first transmission gear 302 and the third transmission gear 304, and the second transmission gear 303 and the third transmission gear 304 are both rotatably connected to the clamp body 1 through the connecting shaft 3031.

[0054] A threaded rod 3041 is fixedly connected to the middle of the interior of the third transmission gear 304, and a limit frame 6 is installed on one side of the guide slider 201. The threaded rod 3041 passes through the limit frame 6 and is threadedly connected to the limit frame 6. The limit frame 6 is slidably connected to the clamp body 1 through the guide rail 102. The limit frame 6 fits the guide slider 201, and a fixed sleeve 601 is installed on one side of the limit frame 6. The fixed sleeve 601 is fixedly connected to the clamp body 1, and a spring telescopic rod 602 is installed inside the fixed sleeve 601. One end of the spring telescopic rod 602 extends to the outside of the fixed sleeve 601 and is fixedly connected to the limit frame 6.

[0055] Specifically, during operation, the transmission arm 301 can be moved to rotate the first transmission gear 302, and at the same time drive the second transmission gear 303 and the third transmission gear 304 to rotate. After the third transmission gear 304 rotates, it drives the threaded rod 3041 to rotate. The rotation of the threaded rod 3041 causes the limit frame 6 to move. The limit frame 6 squeezes the outside of the guide slider 201 to keep the position of the clamp disk 2 stable, which is beneficial to extending the service life of the equipment.

[0056] In order to solve the technical problems in the prior art, such as poor automatic adjustment effect of the clamp, poor stability of the clamp, and easy wear on the surface of the clamped object, please refer to Figure 2 、 Figure 6 , providing the following technical solutions:

[0057] A filter valve 402 is installed between the fixed seat 4 and the hydraulic component box 5, and an oil pump 501 is installed on both sides of the hydraulic component box 5. An electromagnetic reversing valve 5011 is installed between the oil pump 501 and the first hydraulic cylinder 3 and the second hydraulic cylinder 503. The electromagnetic reversing valve 5011 is sealed and connected to the first hydraulic cylinder 3 and the second hydraulic cylinder 503 respectively through the oil pipeline, and the oil pump 501 and the contact pressure sensor 205 are electrically connected through the single-chip microcomputer.

[0059] Specifically, during operation, after the position of the clamp body 1 is fixed by the fixing seat 4, the object to be clamped is placed inside the clamping portion 101 for clamping. During the clamping process, the clamp disk 2 senses the pressure between the object and the clamp disk 2 through the contact pressure sensor 205, and then adjusts the oil pump 501 through the single-chip microcomputer to perform automatic adjustment work to adapt to different working environments, reduce wear of the object, and improve processing quality. Because the oil pump 501 simultaneously refuels the first hydraulic cylinder 3 and the second hydraulic cylinder 503, and the oil supply can be adjusted through the filter valve 402, precise adjustment can be made to keep the position of the guide slider 201 stable, and at the same time, improve the clamping effect of the clamp disk 2.

[0060] See also Figure 1 - Figure 6 A method for using an adjustable automatic hydraulic clamp comprises the following steps:

[0061] Step 1: After fixing the position of the clamp body 1 by the fixing seat 4, place the object to be clamped inside the clamping portion 101 and perform the clamping operation;

[0062] Step 2: Regulate the oil pump 501 inside the hydraulic assembly box 5 to guide the hydraulic oil inside the fixing base 4 into the first hydraulic cylinder 3 and the second hydraulic cylinder 503. The second hydraulic cylinder 503 extends, pushing the guide slide 201 to move through the fastener 5031, driving the two clamping plates 2 to clamp the object.

[0063] Step 3: The first hydraulic cylinder 3 is extended to adjust the transmission arm 301. The transmission arm 301 drives the first transmission gear 302 and the fixed cylinder to rotate, causing the shaft sleeve and the rotating shaft 204 to rotate, thereby causing the clamping plate 2 to rotate slowly. During the rotation process, the limiting teeth 203 on the inner surface of the clamping plate 2 tightly squeeze the object to limit the position;

[0064] Step 4: The contact pressure sensor 205 senses the pressure between the object and the fixture plate 2, and the microcontroller adjusts the oil pump 501 to perform automatic adjustment.

[0065] Step 5: The transmission arm 301 moves, causing the first transmission gear 302 to rotate, and at the same time driving the second transmission gear 303 and the third transmission gear 304 to rotate. The rotation of the third transmission gear 304 drives the threaded rod 3041 to rotate. The rotation of the threaded rod 3041 causes the limit frame 6 to move. The limit frame 6 squeezes the outside of the guide slider 201 to keep the position of the clamping plate 2 stable.

[0066] Step 6: After the object is processed, the electromagnetic reversing valve 5011 is opened to introduce the hydraulic oil into the fixing seat 4, the first hydraulic cylinder 3 and the second hydraulic cylinder 503 are contracted, and the two clamping plates 2 release the object.

[0067] Working principle: During operation, after the position of the clamp body 1 is fixed by the fixing seat 4, the object to be clamped is placed inside the clamping portion 101 for clamping. During the clamping process, the clamp plate 2 senses the pressure between the object and the clamp plate 2 through the contact pressure sensor 205, and then adjusts the oil pump 501 through the single chip microcomputer to perform automatic adjustment work to adapt to different working environments, reduce wear of the object, and improve processing quality. Because the oil pump 501 simultaneously refuels the first hydraulic cylinder 3 and the second hydraulic cylinder 503, The oil supply can be adjusted by the filter valve 402, so as to accurately adjust the hydraulic oil inside the fixing seat 4 to the first hydraulic cylinder 3 and the second hydraulic cylinder 503. The second hydraulic cylinder 503 extends, and the fastener 5031 pushes the guide slider 201 to move, driving the two clamping plates 2 to clamp the object, and the position of the guide slider 201 is kept stable by the guide rail 102. The sliding rod passing through the sliding plate 2011 further maintains the stable sliding effect. By extending the first hydraulic cylinder 3, the transmission arm 301 is adjusted, and the transmission The arm 301 drives the first transmission gear 302 and the fixed cylinder to rotate, so that the shaft sleeve and the rotating shaft 204 rotate, thereby causing the clamping plate 2 to rotate slowly. The limiting teeth 203 on the inner surface of the clamping plate 2 tightly squeeze the object during the rotation process to limit the position. The overall structure is formed in one piece, thereby realizing the clamping work, with a simple structure and good stability. The position of the workpiece is kept stable through the positioning of the rotatable clamping plate 2 and the limiting teeth 203, and the use effect is better. The first transmission gear 302 is rotated by the movement of the transmission arm 301. The third transmission gear 304 rotates, and at the same time drives the second transmission gear 303 and the third transmission gear 304 to rotate. After the third transmission gear 304 rotates, it drives the threaded rod 3041 to rotate. The rotation of the threaded rod 3041 causes the limit frame 6 to move. The limit frame 6 squeezes the outside of the guide slider 201 to keep the position of the clamp disk 2 stable, which is beneficial to extending the service life of the equipment. After the object is processed, the electromagnetic reversing valve 5011 is opened, and the hydraulic oil is introduced into the interior of the fixed seat 4. The first hydraulic cylinder 3 and the second hydraulic cylinder 503 contract, and the two clamp disks 2 release the object.

The limit frame squeezes the outside of the guide slider to keep the position of the fixture plate stable. Step 6: After the object is processed, open the electromagnetic reversing valve and introduce the hydraulic oil into the fixed seat. The first hydraulic cylinder and the second hydraulic cylinder will contract and the two clamping plates will release the object.
