[0011] This invention provides a quick clamping device for valve processing. It offers the following advantages: The quick clamping device uses a servo motor to drive a rotating rod, which in turn drives a worm gear. The worm gear's rotation, in turn, drives a worm wheel, which in turn drives a connecting rod. This connecting rod, in turn, drives a first bevel gear at the bottom, which in turn drives a second bevel gear.

[0018] 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.

[0019] In the current technology, when processing valves, there is no flipping mechanism, so the valve needs to be manually removed before processing the other end. This clamping device not only reduces the efficiency of valve processing, but also increases labor costs.

[0020] In view of this, the present invention provides a quick clamping device for valve processing, which solves the problem that in the prior art, when processing valves, there is no flipping mechanism, and the valves need to be manually removed and the other end processed. This clamping device not only reduces the efficiency of valve processing, but also increases labor costs.

[0021] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0022] Example 1: By Figure 1-4It is known that a quick clamping device for valve processing includes a base plate 1, with side plates 3 fixedly connected to both sides of the outer wall of the base plate 1. Two clamping plates 18 are arranged between the two side plates 3. A fixing plate 2 is fixedly connected to the two side plates 3 on the top of the base plate 1. Both clamping plates 18 are equipped with adjustment devices. The flipping device includes a servo motor 9, a rotating rod 10, a housing 11, a worm gear 12, a worm 13, a first bevel gear 14, a second bevel gear 15, a cylinder 16, a connecting rod 25, and a rotating rod 17. The bottom of the servo motor 9 is fixedly connected to the top of the fixing plate 2. The output end of the servo motor 9 is fixedly connected to the rotating rod 10. The end of the rotating rod 10 is rotatably connected to the housing 11 through a sealed bearing. One side of the outer wall of body 11 is fixedly connected to the top of the outer wall of side plate 3, and a worm gear 13 is fixedly connected thereto. A worm wheel 12 is meshed with the outer wall of the worm gear 13. A connecting rod 25 is fixedly connected to the inner wall of the worm wheel 12. The outer wall of the connecting rod 25 is rotatably connected to the housing 11 through a bearing. A first bevel gear 14 is fixedly connected to the end of the connecting rod 25. A second bevel gear 15 is meshed with the outer wall of the first bevel gear 14. A rotating rod 17 is fixedly connected to the inner wall of the second bevel gear 15. The rotating rod 17 passes through side plate 3 through a bearing and is fixedly connected to a cylinder 16. The output end of the cylinder 16 is fixedly connected to clamp plate 18. The model of servo motor 9 is ECMA-E11320RS, and the model of cylinder 16 is MOB.

[0023] In the specific implementation process, it is worth noting that the side plate 3 is used to fix and install the flipping device, the fixing plate 2 is used to fix the servo motor 9, the rotating rod 10 is used to drive the worm gear 13 through the servo motor 9, and the worm gear 13 drives the worm wheel 12 to rotate. The connecting rod 25 is used to drive the cylinder 16 to rotate through the second bevel gear 15. The cylinder 16 is used to adjust the lateral position of the clamping plate 18. Through the self-locking function of the worm wheel 12 and the worm gear 13, it can be ensured that the clamping plate 18 will not shake during operation when it is not flipped. The specific working principle is that the servo motor 9 drives the rotating rod 10 to rotate. The rotating rod 10 drives the worm gear 13 to rotate, which in turn drives the worm wheel 12 to rotate. The worm wheel 12 drives the connecting rod 25 to rotate, which in turn drives the first bevel gear 14 at the bottom to rotate. The first bevel gear 14 then drives the second bevel gear 15 to rotate, which in turn drives the rotating rod 17 to rotate. The rotating rod 17 drives the cylinder 16 and the clamping plate 18 to rotate. This allows the device to rotate the valve after processing, thus avoiding the need for manual removal of the valve and processing of the other end. This clamping device not only reduces the efficiency of valve processing but also increases labor costs.

[0024] Furthermore, the clamping plate 18 is provided with adjusting rods 19 at both the top and bottom, and a fastening block 21 is provided between the two adjusting rods 19. A threaded rod 20 is movably connected to the side of the fastening block 21 near the adjusting rod 19. The threaded rod 20 is threadedly connected to the clamping plate 18 and fixedly connected to the adjusting rod 19. A ball 27 is fixedly connected to the bottom of the threaded rod 20, and the ball 27 is embedded in the top groove of the fastening block 21.

[0025] In the specific implementation process, it is worth noting that the function of the adjusting rod 19 is to adjust the threaded rod 20, and the function of the fastening block 21 is to clamp the valve. By rotating the threaded rod 20 through the adjusting rod 19, the fastening block 21 is driven to rotate, so that the two fastening blocks 21 are adjusted to the appropriate position, thereby realizing that the outer wall of valves with different pipe diameters can be clamped.

[0026] Specifically, when using this quick clamping device for valve processing, the side plate 3 is used to fix and install the flipping device, the fixing plate 2 is used to fix the servo motor 9, the rotating rod 10 is used to drive the worm gear 13 through the servo motor 9, and the worm gear 13 drives the worm wheel 12 to rotate. The connecting rod 25 is used to drive the cylinder 16 to rotate through the second bevel gear 15. The cylinder 16 is used to adjust the lateral position of the clamping plate 18. The specific working principle is as follows: the servo motor 9 drives the rotating rod 10 to rotate, the rotating rod 10 drives the worm gear 13 to rotate, the rotation of the worm gear 13 drives the worm wheel 12 to rotate, and the rotation of the worm wheel 12 drives the connecting rod 25 to rotate, which in turn drives the first bevel gear at the bottom. When wheel 14 rotates, the first bevel gear 14 drives the second bevel gear 15 to rotate. The rotation of the second bevel gear 15 drives the rotating rod 17 to rotate. The rotating rod 17 drives the cylinder 16 and the clamping plate 18 to rotate. This allows the device to rotate the valve after processing, thus avoiding the need for manual removal of the valve and processing of the other end. This clamping device not only reduces the efficiency of valve processing but also increases labor costs. The adjusting rod 19 is used to adjust the threaded rod 20, and the fastening block 21 is used to clamp the valve. By rotating the threaded rod 20 through the adjusting rod 19, the fastening block 21 is rotated, adjusting the two fastening blocks 21 to the appropriate position, thus enabling clamping of valves with different pipe diameters.

[0027] Example 2: From Figure 1 and 2It is known that a handwheel 23 is provided on the top of the fixed plate 2, and a double-acting screw 22 is fixedly connected to the bottom of the handwheel 23. The double-acting screw 22 passes through the fixed plate 2 and is rotatably connected to the fixed plate 2 through a bearing. A cover 24 is sleeved on the outer wall of the double-acting screw 22. The bottom of the cover 24 is fixedly connected to the top of the base plate 1. A top plate 26 is threadedly connected to the upper part of the outer wall of the double-acting screw 22. The outer wall of the top plate 26 is slidably engaged with the inner wall of the cover 24. A mounting plate 4 is provided at the bottom of the top plate 26. The mounting plate 4 is threadedly connected to the lower part of the outer wall of the double-acting screw 22. The outer wall of the mounting plate 4 is slidably engaged with the inner wall of the cover 24.

[0028] In the specific implementation process, it is worth noting that the function of the handwheel 23 is to adjust the double-acting screw 22 by rotating the handwheel 23. The function of the double-acting screw 22 is to adjust the position of the top plate 26 and the mounting plate 4. The working principle is that the double-acting screw 22 is rotated by the handwheel 23, and the double-acting screw 22 in turn drives the top plate 26 and the mounting plate 4 to adjust. The cover 24 on its outer wall can limit the top plate 26 and the mounting plate 4, and can ensure that they do not deviate during the movement.

[0029] Furthermore, a cavity 5 is provided on the top of the mounting plate 4, and a protrusion 6 fits into the inner wall of the cavity 5. Fixing blocks 7 are fixedly connected to both sides of the protrusion 6, and the fixing blocks 7 are fixed to the top of the mounting plate 4 by bolts.

[0030] In the specific implementation process, it is worth noting that the cavity 5 plays a positioning role when installing the fixing block 7. By inserting the protrusion 6 into the cavity 5, it can be installed quickly. The protrusion 6 and the fixing block 7 together form a support structure for supporting the bottom of the valve. The top of the protrusion 6 is a groove that matches the valve, which can improve the stability of the valve fixing. At the same time, different specifications of protrusion 6 can be replaced according to the valve to be processed to ensure that the quick clamping device used for valve processing is compatible with the valve being processed.

[0031] Furthermore, a fan 8 is fixedly connected to the bottom of the outer wall of the side plate 3, and the output end of the fan 8 extends between the two side plates 3. The model of the fan 8 is not limited, as long as it meets the requirements of the scheme.

[0032] In the specific implementation process, it is worth noting that the function of the blower 8 is to blow air onto the workpiece and other devices to prevent damage to the devices caused by the high temperature generated during valve processing.

[0033] Specifically, based on the above embodiment one, the handwheel 23 is used to adjust the double-acting screw 22 by rotating the handwheel 23. The double-acting screw 22 is used to adjust the position of the top plate 26 and the mounting plate 4. The working principle is that the double-acting screw 22 is rotated by the handwheel 23, and the double-acting screw 22 in turn drives the top plate 26 and the mounting plate 4 to adjust. The cover 24 on its outer wall can limit the top plate 26 and the mounting plate 4 to ensure that they do not deviate during the movement. The cavity 5 is used to position the mounting block 7. By inserting the protrusion 6 into the cavity 5, it can be installed quickly. The fan 8 is used to blow air on the workpiece and other devices to prevent damage caused by the high temperature generated during valve processing.
