Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0021] When the existing trimming device for valve production fixes the valve on the workbench, bolts are used to press against the outer wall of the valve for fixation. Then, the grinding disc grinds it. The high-speed rotation of the grinding disc easily causes the valve to shake. When grinding under the shaking condition, the ground surface is not uniform enough.
[0022] In view of this, the present invention provides a trimming device for valve production. Through the cooperation among the first servo motor, the fixed plate and the fixing piece, the top of the valve is first fixed. Then, the valve is moved downward to a position flush with the fixing piece. The first servo motor is started, and the first servo motor drives the bidirectional lead screw to rotate. The bidirectional lead screw drives the two fixed plates threadedly connected to the outer wall to move in opposite directions. The two fixed plates can drive the two fixing pieces to press against both sides of the outer wall of the valve. Moreover, the outer wall of the fixing piece is covered with a rubber pad, which can increase the friction between the fixing piece and the valve, so that the valve will not shake during the trimming process.
[0023] Persons skilled in the art can connect the components in this case in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process.
[0024] Embodiment 1: As Figures 1-5 can be seen, a trimming device for valve production includes a workbench 1. A first opening 19 and two second openings 2 are provided at the top of the workbench 1. Grinding discs 15 are arranged on both sides above the workbench 1. A fixing device is arranged at the top of the workbench 1. The fixing device includes a first servo motor 3, a bidirectional lead screw 4, a fixing plate 5 and a fixing part 20. Both ends of the bidirectional lead screw 4 are rotatably connected to the inner wall of the workbench 1 through bearings. One end of the bidirectional lead screw 4 penetrates through the back of the workbench 1 through a bearing and is fixedly connected to the first servo motor 3. The first servo motor 3 is fixedly connected to the outer wall of the workbench 1. Two fixing plates 5 are threadedly connected to the outer wall of the bidirectional lead screw 4. The tops of the two fixing plates 5 are movably connected to the first opening 19 and extend to the top of the workbench 1. Fixing parts 20 are fixedly connected to the opposite sides of the tops of the two fixing plates 5. A damping layer is covered on the outer wall of the fixing part 20, which can increase the friction between the valve and the fixing part 20 and ensure that the valve does not shake during the trimming process.
[0025] In the specific implementation process, it is particularly pointed out that first fix the top of the valve, and then move the valve downward to a position flush with the fixing part 20. Start the first servo motor 3. The first servo motor 3 drives the bidirectional lead screw 4 to rotate. The bidirectional lead screw 4 drives the two fixing plates 5 threadedly connected to the outer wall to move in opposite directions. The two fixing plates 5 can drive the two fixing parts 20 to tightly press against both sides of the outer wall of the valve. A damping layer is covered on the outer wall of the fixing part 20, which can increase the friction between the fixing part 20 and the valve and prevent the valve from shaking during the trimming process.
[0026] Furthermore, an insertion plate 22 is arranged above the workbench 1. Sleeve shells 16 are sleeved on both sides of the outer wall of the insertion plate 22. An L-shaped clamping plate 21 is fixedly connected to the bottom of the sleeve shell 16. The sleeve shell 16 can be driven by the second electric slider 11 to control how much the insertion plate 22 enters the inner wall of the sleeve shell 16, so as to control the distance between the two sleeve shells 16.
[0027] In the specific implementation process, it is particularly worth noting that when fixing the top of the valve, first start the second electric slider 11. The second electric slider 11 drives the telescopic rod 17, and the telescopic rod 17 drives the sleeve 16, so that the distance between the two sleeves 16 adapts to the size of the top of the valve. After adjustment, place the top of the valve on the top of the L-shaped clamping plate 21. Then, driven by the sleeve 16 and the second electric slider 11, the L-shaped clamping plate 21 makes the opposite sides of the two L-shaped clamping plates 21 abut tightly. The opening at the top of the L-shaped clamping plate 21 can fix the adjustment part of the valve, realizing the fixation of the top of the valve. With the cooperation of the two fixing parts 20, it can ensure that the valve will not shake during the trimming process;
[0028] Specifically, when using this trimming device for valve production, when fixing the top of the valve, first start the second electric slider 11. The second electric slider 11 drives the telescopic rod 17, and the telescopic rod 17 drives the sleeve 16, so that the distance between the two sleeves 16 adapts to the size of the top of the valve. After adjustment, place the top of the valve on the top of the L-shaped clamping plate 21. Then, driven by the sleeve 16 and the second electric slider 11, the L-shaped clamping plate 21 makes the opposite sides of the two L-shaped clamping plates 21 abut tightly. The opening at the top of the L-shaped clamping plate 21 can fix the adjustment part of the valve, realizing the fixation of the top of the valve. First fix the top of the valve, and then move the valve downward to a position flush with the fixing part 20. Start the first servo motor 3. The first servo motor 3 drives the bidirectional lead screw 4 to rotate. The bidirectional lead screw 4 drives the two fixing plates 5 threadedly connected to the outer wall to move in opposite directions. The two fixing plates 5 can drive the two fixing parts 20 to abut tightly against both sides of the outer wall of the valve. And the outer wall of the fixing part 20 is covered with a damping layer, which can increase the friction between the fixing part 20 and the valve, so that the valve will not shake during the trimming process.
[0029] Embodiment 2: As Figures 1-5 It can be seen that the inner walls of the two second openings 2 are both slidably clamped with movable plates 7. The bottom of the movable plate 7 can move on the inner walls of the two second openings 2. The outer walls of the two movable plates 7 are both fixedly connected with second servo motors 6. The output ends of the second servo motors 6 pass through the outer walls of the movable plates 7 through bearings and are fixedly connected with sleeves 14. The outer wall of the grinding disc 15 is fixedly connected to the inner wall of the sleeve 14 by bolts;
[0030] In the specific implementation process, it is particularly worth noting that after the valve is fixed, the two grinding discs 15 approach the two sides of the valve driven by the first electric slider 8, and the trimming work can be carried out on both sides of the valve at the same time. And the grinding disc 15 is fixedly connected to the inner wall of the sleeve 14 by bolts and can be replaced according to different specifications of the valve, so as to meet the trimming work of valves with different specifications;
[0031] Furthermore, mounting plates 18 are fixedly connected to both sides of the outer wall of the workbench 1. Support rods 13 are fixedly connected to the tops of the two mounting plates 18. A straight plate 12 is arranged above the workbench 1. The bottom of the straight plate 12 is fixedly connected to the top of the support rod 13. An electric slide rail 9 is fixedly connected to the bottom of the straight plate 12. Two first electric sliders 8 are slidably clamped to the outer wall of the electric slide rail 9. The bottoms of the two first electric sliders 8 are respectively fixedly connected to the tops of the two movable plates 7. The models of the electric slide rail 9 and the first electric sliders 8 are not specifically described herein;
[0032] In the specific implementation process, it is particularly pointed out that the two movable plates 7 can slide on the outer wall of the electric slide rail 9 through the first electric sliders 8, so as to control the distance between the grinding disc 15 and both sides of the valve. After the valve is fixed, start the first electric slider 8, which can drive the movable plate 7, and the movable plate 7 drives the grinding disc 15 to achieve the purpose of trimming both sides of the valve simultaneously;
[0033] Furthermore, a cylinder 10 is fixedly connected to the top of the straight plate 12. The output end of the cylinder 10 penetrates through the top of the straight plate 12 and is fixedly connected to the top of the insertion plate 22;
[0034] In the specific implementation process, it is particularly pointed out that the top fixing device controls the position of the valve through the cylinder 10. After the top of the valve is fixed, the output end of the cylinder 10 drives the valve to a position flush with the fixing member 20;
[0035] Furthermore, two second electric sliders 11 are slidably clamped to the outer wall of the electric slide rail 9. The bottoms of the two second electric sliders 11 are both fixedly connected to the tops of two telescopic rods 17. The two telescopic rods 17 can be composed of a cylinder body and an insertion rod. The telescopic function is achieved by changing the insertion distance between the insertion rod and the cylinder body. Its purpose is to limit the position between the two sleeve shells 16 and the two second electric sliders 11 to ensure the horizontality of the L-shaped clamping plate 21;
[0036] In the specific implementation process, it is particularly pointed out that the sleeve shell 16 moves under the drive of the second electric slider 11, so as to control the distance between the two sleeve shells 16. When the output end of the cylinder 10 drives the insertion plate 22 to move downward, the two sleeve shells 16 move downward together under the drive of the telescopic rod 17, and the telescopic rod 17 also plays a limiting role;
[0037] Specifically, on the basis of the above-mentioned first embodiment, the housing 16 moves driven by the second electric slider 11 to control the distance between the two housings 16. When the output end of the cylinder 10 drives the plug board 22 to move downward, the two housings 16 move downward together driven by the telescopic rod 17, and the telescopic rod 17 also plays a role in limiting. After fixing the top, the top fixing device controls the position of the valve through the cylinder 10. After fixing the top of the valve, the output end of the cylinder 10 drives the valve to a position flush with the fixing member 20. After fixing the valve, the two grinding discs 15 approach both sides of the valve driven by the first electric slider 8, and the trimming work can be carried out on both sides of the valve at the same time. Moreover, the grinding disc 15 is fixed to the inner wall of the sleeve 14 by bolts and can be replaced according to different specifications of the valve, so as to meet the requirement of trimming valves of different specifications. The two movable plates 7 can slide on the outer wall of the electric slide rail 9 through the first electric slider 8 to control the distance between the grinding disc 15 and both sides of the valve. After the valve is fixed, starting the first electric slider 8 can drive the movable plate 7, and the movable plate 7 drives the grinding disc 15 to achieve the purpose of trimming both sides of the valve at the same time.
