Description

Technical Field

[0001] The present invention relates to the technical field of valve body processing, and in particular to an automatic processing equipment for gas valve bodies. Background Art

[0002] A gas emergency cut-off valve is a valve specifically designed to quickly and automatically shut off the gas supply when detecting gas leakage or other abnormal conditions. This valve plays a crucial role in ensuring user safety and preventing fire and explosion accidents. After the valve body of the gas emergency cut-off valve is initially formed, in order to provide the connection sealing between the valve body and pipelines or other equipment, it is necessary to deburr the flange surface of the valve body.

[0003] In the prior art, when deburring the flange surface of the valve body, generally a fixture is used to vertically clamp the valve body so that one flange surface faces upward, and then the robotic arm drives the deburring equipment to deburr the flange surface.

[0037] The present invention provides an automatic processing device for a gas valve body, which includes a robotic arm 1 and a deburring device 2, and further includes a clamping assembly. The clamping assembly includes a base 3, a mounting seat 4, a mounting shaft 5, a clamping mechanism 6, a driven gear 7, a servo motor 8, a driving gear 9, and a locking mechanism 10. The clamping mechanism 6 includes a mounting box 61, two first sliders 62, a first bidirectional lead screw 63, two first knobs 64, and two clamping members 65. The first slider 62 has a chute 621. The clamping member 65 includes two second sliders 651, two clamping blocks 652, a second bidirectional lead screw 653, and two second knobs 654. The clamping member 65 further includes two friction pads 655. The mounting seat 4 has a first locking hole 41. The driven gear 7 has two second locking holes 71. The locking mechanism 10 includes a mounting frame 101, a first hydraulic cylinder 102, a locking rod 103, and a connecting plate 104. The clamping assembly further includes a second hydraulic cylinder 11 and a tray 12. The clamping assembly further includes a support plate 13, a steering gear 14, and a brush rod 15. The clamping assembly further includes a lifting mechanism 16 and a flat nozzle 17. The lifting mechanism 16 includes a vertical frame 161, a third slider 162, a driving lead screw 163, and a third knob 164. Through the foregoing solution, the processing efficiency can be effectively improved.

[0038] Further, the deburring device 2 is disposed on one side of the robotic arm 1. The base 3 is located on one side of the robotic arm 1. The mounting seat 4 is fixedly disposed on the top of the base 3. The mounting shaft 5 is rotatably disposed on the mounting seat 4 and passes through the mounting seat 4. The clamping mechanism 6 is fixedly disposed on one side of the mounting shaft 5. The driven gear 7 is fixedly disposed on the side of the mounting shaft 5 away from the clamping mechanism 6. The servo motor 8 is fixedly disposed on one side of the mounting seat 4. The driving gear 9 is fixedly disposed at the output end of the servo motor 8 and meshes with the driven gear 7. The locking mechanism 10 is disposed on the mounting seat 4 for locking the driven gear 7.

[0039] In this embodiment, the robotic arm 1 is used to drive the deburring device 2 to move, and can deburr the flange surface of the valve body. One end of the mounting shaft 5 is provided with the clamping mechanism 6, and the other end is provided with the driven gear 7. Therefore, the clamping mechanism 6 can rotate. The clamping mechanism 6 is used to clamp the valve body. The servo motor 8 drives the driving gear 9, and the driving gear 9 can drive the engaged driven gear 7 to rotate. The locking mechanism 10 can lock the driven gear 7 so that it cannot rotate, making the mounting shaft 5 unable to rotate, and the clamping mechanism 6 unable to rotate either.

[0040] During use, the valve body is vertically clamped on the clamping mechanism 6, such that one flange surface of the valve body faces upward. At this time, the locking mechanism 10 locks the driven gear 7, the mounting shaft 5 cannot rotate, and the clamping mechanism 6 cannot rotate either. Then, the mechanical arm 1 drives the deburring device 2 to automatically deburr the upward-facing flange surface. After deburring, the locking mechanism 10 releases the driven gear 7, the servo motor 8 drives the driving gear 9, the driving gear 9 drives the driven gear 7, and the driven gear 7 rotates 180 degrees. The clamping mechanism 6 is driven by the mounting shaft 5 to rotate 180 degrees, thereby flipping the clamped valve body 180 degrees, making the other flange surface face upward. Then, the locking mechanism 10 locks the driven gear 7, and the mechanical arm 1 drives the deburring device 2 to automatically deburr the upward-facing flange surface; thus, the processing efficiency can be effectively improved.

[0041] Furthermore, the clamping mechanism 6 includes a mounting box 61, two first sliders 62, a first bidirectional lead screw 63, two first knobs 64, and two clamping members 65;

[0042] The mounting box 61 is fixedly arranged on the side of the mounting shaft 5 away from the driven gear 7; the two first sliders 62 are respectively slidably arranged in the mounting box 61; the first bidirectional lead screw 63 is rotatably connected to the mounting box 61, threadedly connected to the two first sliders 62 respectively, and passes through the two first sliders 62 respectively; the two first knobs 64 are respectively fixedly arranged at both ends of the first bidirectional lead screw 63; the two clamping members 65 are respectively arranged on the two first sliders 62.

[0043] In this embodiment, the two first knobs 64 are used to facilitate the rotation of the first bidirectional lead screw 63. Rotating the first bidirectional lead screw 63 can drive the two first sliders 62 to slide in the mounting box 61 in opposite directions, thereby driving the two clamping members 65 to slide in opposite directions. The two clamping members 65 respectively clamp the parts near the two flanges of the valve body, so different lengths of valve bodies can be adapted for clamping.

[0044] Furthermore, the first slider 62 has a chute 621; the clamping member 65 includes two second sliders 651, two clamping blocks 652, a second bidirectional screw 653, and two second knobs 654;

[0045] The two second sliders 651 are respectively slidably arranged in the chute 621; the two clamping blocks 652 are respectively fixedly arranged on one side of the two second sliders 651; the second bidirectional screw 653 is rotationally connected to the first slider 62, threadedly connected to the two second sliders 651 respectively, and passes through the two second sliders 651 respectively; the two second knobs 654 are respectively fixedly arranged at both ends of the second bidirectional screw 653.

[0046] In this embodiment, the two second knobs 654 are used to facilitate the rotation of the second bidirectional screw 653. Rotating the second bidirectional screw 653 can drive the two second sliders 651 to slide in opposite directions, thereby driving the two clamping blocks 652 to slide in opposite directions. The clamping block 652 has a V-shaped groove. After the two clamping blocks 652 are closed to clamp the valve body, they are close to the flange. The top surfaces of the two upper clamping blocks 652 are close to the bottom surface of the upper flange, and the bottom surfaces of the two lower clamping blocks 652 are close to the top surface of the lower flange, so that the valve body can be clamped and the valve body cannot move up and down.

[0047] Furthermore, the clamping member 65 further includes two friction pads 655;

[0048] The two friction pads 655 are respectively fixedly arranged on the sides of the two clamping blocks 652.

[0049] In this embodiment, the friction pads 655 are used to increase the friction force between the clamping blocks 652 and the valve body, so that the valve body cannot rotate and avoid rotation during the deburring process.

[0050] Furthermore, the mounting seat 4 has a first locking hole 41; the driven gear 7 has two second locking holes 71; the locking mechanism 10 includes a mounting frame 101, a first hydraulic cylinder 102, a locking rod 103 and a connecting plate 104;

[0051] The mounting frame 101 is fixedly arranged on the top of the mounting seat 4; the first hydraulic cylinder 102 is fixedly arranged on the top of the mounting frame 101; the locking rod 103 is slidably connected to the mounting frame 101 and passes through the mounting frame 101; the upper end of the connecting plate 104 is fixedly connected to the output end of the first hydraulic cylinder 102, and the lower end of the connecting plate 104 is fixedly connected to the locking rod 103.

[0052] In this embodiment, the locking rod 103 is adapted to the first locking hole 41 and the second locking hole 71. When the locking rod 103 passes through the second locking hole 71 and is inserted into the first locking hole 41, the driven gear 7 can be locked. The mounting bracket 101 is used for slidably mounting the locking rod 103, and the first hydraulic cylinder 102 drives the locking rod 103 to slide through the connecting plate 104. When the locking rod 103 withdraws from the first locking hole 41 and then from the second locking hole 71, the driven gear 7 can rotate. After rotating 180 degrees, another second locking hole 71 is aligned with the first locking hole 41. At this time, when the locking rod 103 passes through the second locking hole 71 and is inserted into the first locking hole 41, the driven gear 7 can be locked again.

[0053] Further, the clamping assembly further includes a second hydraulic cylinder 11 and a tray 12.

[0054] The second hydraulic cylinder 11 is fixedly arranged on the base 3 and passes through the base 3. The tray 12 is fixedly arranged at the output end of the second hydraulic cylinder 11.

[0055] In this embodiment, when the valve body is vertically clamped, the second hydraulic cylinder 11 drives the tray 12 to rise, and supports the valve body from the flange at the bottom of the valve body, so that the valve body remains vertically stable and avoids moving randomly during the deburring process. When the valve body needs to be flipped, the second hydraulic cylinder 11 drives the tray 12 to move down to avoid interference.

[0056] Further, the clamping assembly further includes a support plate 13, a servo motor 14 and a brush rod 15.

[0057] The support plate 13 is fixedly arranged on one side of the tray 12. The servo motor 14 is fixedly arranged at the bottom of the support plate 13. The brush rod 15 is fixedly connected to the output end of the servo motor 14 and is located at the top of the support plate 13.

[0058] In this embodiment, the waste chips generated during the deburring process will fall onto the tray 12. In order to prevent the tray 12 from scratching the flange surface when supporting the flange of the valve body with the chips, the servo motor 14 is provided. The servo motor 14 drives the brush rod 15 to rotate and sweep across the surface of the tray 12 to sweep away the chips.

[0059] Further, the clamping assembly further includes a lifting mechanism 16 and a flat nozzle 17.

[0060] The lifting mechanism 16 is fixedly arranged on the top of the base 3. The flat nozzle 17 is arranged on the lifting mechanism 16, and the lifting mechanism 16 is used for lifting and adjusting the height position of the flat nozzle 17.

[0061] In this embodiment, the flat nozzle 17 is connected to a high-pressure gas source. The height of the flat nozzle 17 is adjusted by the lifting mechanism 16 so that the flat nozzle 17 blows air onto the flange surface above the valve body during deburring, blowing off the debris generated during the deburring process to achieve a cleaning effect.

[0062] Further, the lifting mechanism 16 includes a vertical frame 161, a third slider 162, a driving lead screw 163, and a third knob 164.

[0063] The vertical frame 161 is fixedly arranged on the top of the base 3; the third slider 162 is slidably arranged inside the vertical frame 161 and is fixedly connected to the flat nozzle 17; the driving lead screw 163 is rotatably arranged on the vertical frame 161 and is threadedly connected to the third slider 162; the third knob 164 is fixedly arranged on the top of the driving lead screw 163.

[0064] In this embodiment, the third knob 164 is used to conveniently rotate the driving lead screw 163. The driving lead screw 163 drives the third slider 162 to slide, and the third slider 162 drives the flat nozzle 17 to move up and down.

[0065] When the automatic processing equipment for a gas valve body described in this embodiment is in use, the valve body is vertically clamped on the clamping mechanism 6 so that one flange surface of the valve body faces upward. At this time, the locking mechanism 10 locks the driven gear 7, the mounting shaft 5 cannot rotate, and the clamping mechanism 6 cannot rotate either. Then, the mechanical arm 1 drives the deburring device 2 to automatically deburr the upward-facing flange surface. After deburring, the locking mechanism 10 releases the driven gear 7, the servo motor 8 drives the driving gear 9, the driving gear 9 drives the driven gear 7, and the driven gear 7 rotates 180 degrees. The clamping mechanism 6 is driven by the mounting shaft 5 to rotate 180 degrees, so that the clamped valve body is flipped 180 degrees, making the other flange surface face upward. Then, the locking mechanism 10 locks the driven gear 7, and the mechanical arm 1 drives the deburring device 2 to automatically deburr the upward-facing flange surface; thus, the processing efficiency can be effectively improved.
