[0024] Example 1:

[0025] A positioning and clamping device for valve body processing includes a drilling device body 1, a drilling head 2 and a water spray head 3. Water spray heads 3 are provided on both sides of the drilling head 2 on the drilling device body 1. The water spray heads 3 are used for water spray cooling during the drilling process. The bottom of the drilling head 2 is provided with a valve body 9 through a positioning and clamping mechanism 8. The positioning and clamping mechanisms 8 are symmetrically arranged on both sides of a turntable 7. The turntable 7 is arranged in the center of the inner cavity of a collection box 4, and the turntable 7 is fixedly installed on a rotating mechanism 6. The rotating mechanism 6 is used to drive the rotation of the turntable 7 and switch the two sets of positioning and clamping mechanisms 8 on the turntable 7.

[0026] The rotating mechanism 6 includes a servo motor 601, a worm 602, a worm wheel 603, a support rod 604 and a rotating shaft 605. The servo motor 601 is fixedly installed at the bottom of the collection box 4, and the output end of the servo motor 601 is connected and fixed to one end of the worm 602 through a coupling. The worm 602 is transmission-connected to the worm wheel 603 arranged at the bottom end of the support rod 604. The support rod 604 is rotationally connected to the center of the interior of the collection box 4 through the rotating shaft 605, and the top end of the support rod 604 is fixedly connected to the center of the turntable 7.

[0027] A support cylinder 10 is fixedly installed in the center of the inner cavity of the collection box 4. The top surface of the support cylinder 10 is rotatably connected to the bottom surface of the turntable 7, and the interior of the support cylinder 10 is rotatably connected to the support rod 604. By setting the support cylinder 10, further support for the turntable 7 is achieved, thereby ensuring the stability of the turntable 7.

[0028] By setting a turntable 7 in the collection box 4 and setting a rotating mechanism 6 at the bottom of the turntable 7, the rotating mechanism 6 is used to realize automatic switching processing and loading and unloading of the valve bodies 9 on both sides of the turntable 7, thereby improving work efficiency, and the servo motor 601 is used to drive the worm 602 to rotate. Since the worm 602 is connected to the worm wheel 603 at the bottom end of the support rod 604, and the support rod 604 is connected to the center of the interior of the collection box 4 through the rotating shaft 605, the support rod 604 can be driven by the servo motor 601 to rotate, thereby rotating the turntable 7, realizing the switching of the positioning clamping mechanisms 8 on both sides of the turntable 7, thereby realizing the switching of the processing of the valve body 9, thereby saving loading and unloading time and improving work efficiency.

[0029] A filter head 11 is provided in the inner cavity of the collecting box 4, and the filter head 11 is provided in the water outlet in the inner cavity of the collecting box 4. An outlet pipe 12 is provided at the bottom of the water outlet. The setting of the filter head 11 realizes the filtration of the waste material of the valve body 9 in the collecting box 4, and the filtered waste material is centrally processed in the inner cavity of the collecting box 4, and the water sprayed from the sprinkler head 3 is centrally collected and processed through the filter head 11 and the outlet pipe 12. By setting the turntable 7 in the inner cavity of the collecting box 4, the wastewater and waste in the processing process can be centrally collected and processed through the collecting box 4.

[0030] The positioning and clamping mechanism 8 includes an electric telescopic rod 801, a slider 802, a mobile clamping block 803, a positioning clamping block 804, a fixed block 805 and a slide groove 806. The electric telescopic rod 801 is symmetrically arranged on both sides of the bottom of the turntable 7, and the output end of the electric telescopic rod 801 is fixedly connected to the bottom of the slider 802, and the slider 802 is slidably connected to the slide groove 806 opened on both sides of the turntable 7. The mobile clamping block 803 is fixedly installed on the top of the slider 802, and a positioning clamping block 804 is provided on one side of the mobile clamping block 803 through the fixed block 805, and the fixed block 805 is fixedly installed on the turntable 7.

[0031] The positioning and clamping mechanism 8 further includes a positioning seat 807 , which is fixedly mounted on the turntable 7 and is used to support the flanges on both sides of the valve body 9 .

[0032] By setting up a positioning and clamping mechanism 8, the valve body 9 is positioned, clamped and fixed to ensure stability during the drilling process. The positioning seat 807 is used to support the flanges on both sides of the valve body 9. The positioning and clamping block 804 on the upper part of the fixed block 805 is used to position and clamp one side of the valve body 9. Then, by driving the electric telescopic rod 801 through the slider 802, the mobile clamping block 803 is driven to approach the positioning clamping block 804, so that the valve body 9 is clamped and fixed, thereby ensuring the stability of the valve body 9.

[0033] A hanging ring 14 is provided on the collection box 4, and the hanging ring 14 is used to hang a handheld air gun 13. The handheld air gun 13 is connected to the air pump through an air pipe. The handheld air gun 13 is used to remove drilling waste. Drilling waste will be generated in the process of drilling the flanges at both ends of the valve body 9. The staff can open the handheld air gun 13 to blow the waste on the turntable 7 into the inner cavity of the collection box 4 for centralized collection to ensure the cleanliness of the turntable 7.

[0034] Working principle: By setting the turntable 7 in the inner cavity of the collection box 4, the wastewater and waste materials in the processing of the valve body 9 are collected centrally through the collection box 4 and then processed separately to improve the recycling efficiency. By fixing the turntable 7 on the rotating mechanism 6, the rotating mechanism 6 is used to rotate the turntable 7, and the positioning clamping mechanisms 8 on both sides are rotated to switch loading and unloading, thereby improving work efficiency. The positioning clamping mechanism 8 is used to clamp and fix the valve body 9 to ensure stability during the processing;

[0035] First, the staff stands in front of the collection box 4 and places the corresponding positioning clamping block 804 on the positioning seat 807 on one side of the valve body 9. Then, the electric telescopic rod 801 on the bottom side of the turntable 7 is driven to clamp the other side of the valve body 9 by moving the clamping block 803 closer, so that the valve body 9 is fixed between the positioning clamping block 804 and the movable clamping block 803. Then, the rotating mechanism 6 is used to rotate the valve body 9 clamped and fixed in front of the staff to the bottom of the drilling head 2 on the drilling device main body 1 for drilling. During the drilling process, the staff can re-load the valve body 9 and clamp it on the positioning clamping mechanism 8 on the other side of the turntable 7. When the flange at one end of the valve body 9 at the bottom of the drilling head 2 is drilled, the rotating mechanism 6 is used to switch and rotate the drilled valve body 9 to the front of the staff. The staff flips the valve body 9 and clamps the flange at the other end upwards. Finally, the drilling process is performed by switching, thereby reducing the downtime of single loading and unloading and improving work efficiency.
