When the two lifting and adjusting plates contact both ends of the valve body at the same time, the angle between the side wall of the valve body and the drill bit will be adjusted to make the side wall of the valve body perpendicular to the drill bit, so that the holes drilled by the two drill bits can be butt-jointed.

[0019] 4. When drilling, the sliding clamping plate will press the valve body from the top, and the lifting frame and the lifting and adjusting support plate will cooperate to limit it from both sides of the valve body.

[0020] 5. After drilling is completed, the drill bit moves to reset. At this time, the water storage frame drops and sprays the water inside it to the valve body through the nozzle to flush out the debris remaining in the valve body. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] Embodiment 1: A drilling device for oil valve body processing, such as Figure 1-Figure 11 As shown, the guide box 1 includes a guide box 1, a fixed support plate 1001, a movable seat 101, a drill bit 1011, a drilling bracket 102, a bearing support 103, a pushing mechanism and an automatic positioning mechanism. The guide box 1 is fixedly connected with a fixed support plate 1001, and a bottomless slideway for guiding is provided between the fixed support plate 1001 and the guide box 1. Drilling brackets 102 are provided on both sides of the guide box 1. The movable seat 101 is slidably connected to the drilling bracket 102. The drill bit 1011 is installed in the movable seat 101. The movable seat 101 moves along the drilling path. The bracket 102 moves and drives the drill bit 1011 to move toward the valve body to drill a through hole in the valve body. The guide box 1 is slidably connected with a bearing support 103, and the bearing support 103 is slidably set in a bottomless slide between the fixed support plate 1001 and the guide box 1. The pushing mechanism is installed in the guide box 1, and the pushing mechanism is used to drive the bearing support 103 to slide in the guide box 1. The automatic positioning mechanism is installed on the bearing support 103, and the automatic positioning mechanism is used to adjust the position of the valve body so that the valve body is aligned with the drill bit 1011.

[0035] Before drilling, the pushing mechanism drives the bearing support 103 to move along the guide box 1 to the end away from the drilling bracket 102, and then the valve body is placed on the bearing support 103. Thereafter, the bearing support 103 and the valve body on its top are transported along the guide box 1 to between the two drilling brackets 102 by the pushing mechanism. During the movement, the automatic positioning mechanism adjusts the valve body to the center position of the bearing support 103. When the bearing support 103 moves between the two drilling brackets 102, the valve body on the bearing support 103 moves to the middle of the two drill bits 1011. Then, the moving seat 101 is controlled to move along the drilling bracket 102 in the direction close to the bearing support 103. When the drill bit 1011 is about to contact the valve body When the drilling is completed, the pushing mechanism pushes the bearing support 103 to move along the guide box 1 in the direction away from the drilling support 102, and the valve body that has been drilled moves with the bearing support 103, and the automatic positioning mechanism releases the valve body, removes the valve body that has been drilled from the bearing support 103, and then places the valve body to be drilled on the bearing support 103 to continue drilling.

[0036] Embodiment 2: Based on embodiment 1, Figure 2 As shown, the pushing mechanism includes a control motor 105, a screw rod 106, a movable push plate 107, a guide rod 108, a sliding connection frame 109 and a connecting spring 110. The control motor 105 is installed on the rear side of the guide box 1. The screw rod 106 is rotatably connected in the guide box 1. The output shaft of the control motor 105 is connected to the screw rod 106. The control motor 105 drives the screw rod 106 to rotate. The guide box 1 is fixed with a guide rod 108. The guide rod 108 is slidably connected to the sliding connection frame 109. The sliding connection frame 110 is connected to the guide box 1. A movable push plate 107 is slidably connected to the connecting frame 109, and the movable push plate 107 is threadedly connected to the screw rod 106. When the screw rod 106 rotates, the movable push plate 107 can slide along the sliding connecting frame 109. A connecting spring 110 is provided between the sliding connecting frame 109 and the movable push plate 107. One end of the connecting spring 110 is fixed to the sliding connecting frame 109, and the other end is fixed to the movable push plate 107. The movable push plate 107 pushes the sliding connecting frame 109 to slide along the guide rod 108 through the connecting spring 110.

[0037] When the bearing support 103 is located at the side of the guide box 1 away from the drilling bracket 102, the control motor 105 starts to drive the screw rod 106 to rotate. When the screw rod 106 rotates, it pushes the connecting spring 110 and the sliding connecting frame 109 to slide along the guide rod 108 through the moving push plate 107. When the bearing support 103 moves to the position between the two drilling brackets 102, the sliding connecting frame 109 contacts the inner wall of the guide box 1. At this time, the screw rod 106 continues to rotate. During the drilling process, the moving push plate 107 will push the connecting spring 110 and the sliding connecting frame 109 along the sliding connecting frame 108. The connecting frame 109 slides and compresses the connecting spring 110. When the drilling is completed, the control motor 105 rotates in the opposite direction. At this time, the moving push plate 107 first slides along the sliding connecting frame 109. When the connecting spring 110 returns to its original state, the moving push plate 107 continues to move and drives the sliding connecting frame 109 to slide along the guide rod 108, so as to drive the bearing support 103 to slide along the guide box 1 away from the drilling support 102, so that the valve body and the bearing support 103 that have been drilled are moved out from between the two drilling supports 102.

[0038] like Figure 2-Figure 4 As shown, the automatic positioning mechanism includes a movable support plate 2, a return spring 201, a sliding block 202, a centering spring 203 and a centering push component. The sliding block 202 is slidably connected in the bearing support 103, and a centering spring 203 is provided between the sliding block 202 and the bearing support 103. One end of the centering spring 203 is fixed on the sliding block 202, and the other end is fixed on the bearing support 103. The movable support plate 2 is slidably connected between multiple sliding blocks 202. Under the action of the sliding block 202, the movable support plate 2 can move in the bearing support 103. A return spring 201 is provided between the movable support plate 2 and the sliding block 202. One end of the return spring 201 is fixed on the movable support plate 2, and the other end is fixed on the sliding block 202. The centering push component is installed on the bearing support 103. The centering push component is used to push the valve body on the movable support plate 2 to move and align it with the drill bit 1011.

[0039] After the valve body is placed on the movable support plate 2 in the bearing support 103, the bearing support 103 will be pushed to move along the guide box 1. During the movement of the bearing support 103, the centering component will drive the movable support plate 2 to move in the bearing support 103 through the valve body, so that the valve body moves to the center position in the bearing support 103. When the drilling is completed, the bearing support 103 moves and resets. During this process, the centering component will lose contact with the valve body. At this time, under the action of the return spring 201 and the centering spring 203, the sliding block 202 and the movable support plate 2 will move and reset along the bearing support 103.

[0040] like Figure 2-Figure 4As shown, the pushing centering component includes a fixed pressure rod 1002, a sliding ring 3, a lower rotating shaft 301, a lower positioning clamping rod 3011, an upper rotating shaft 302, an upper positioning clamping rod 3021, a connecting ring 303, a supporting spring 304 and an arc-shaped sliding groove 305. The guide box 1 is fixedly connected with the fixed pressure rod 1002, and the fixed pressure rod 1002 is divided into two sections, a high section and a low section. The bearing support 103 is rotatably connected with the lower rotating shaft 301, and the lower rotating shaft 301 is fixedly connected with the lower positioning clamping rod 3011 on the outside, and the lower positioning clamping rod 3011 rotates with the lower rotating shaft 301. The lower rotating shaft 301 is rotatably connected with the upper rotating shaft 302, and the upper rotating shaft 302 is fixedly connected with the upper positioning clamping rod 3021 on the outside, and the upper positioning clamping rod 3021 rotates with the upper rotating shaft 302. The lower rotating shaft 301 is slidably connected with the sliding ring 3 on the outside. When the bearing support 103 moves to a lower section of the fixed pressure rod 1002, The sliding ring 3 will be pushed by the fixed pressure rod 1002 and slide downward along the lower rotating shaft 301. A supporting spring 304 is provided between the sliding ring 3 and the bearing support 103. One end of the supporting spring 304 is fixed on the bearing support 103, and the other end is fixed on the sliding ring 3. A connecting ring 303 is fixedly connected to the sliding ring 3. The lower rotating shaft 301 and the upper rotating shaft 302 are both provided with arc-shaped sliding grooves 305. The arc-shaped sliding grooves 305 outside the lower rotating shaft 301 and the upper rotating shaft 302 are set in opposite directions. The sliding ring 3 matches the arc-shaped sliding grooves 305 outside the lower rotating shaft 301, and the connecting ring 303 matches the arc-shaped sliding grooves 305 outside the upper rotating shaft 302. When the sliding ring 3 and the connecting ring 303 descend, the lower rotating shaft 301 and the upper rotating shaft 302 rotate in opposite directions. At the same time, the positions of the valve body and the movable support plate 2 are adjusted by the lower positioning clamping rod 3011 and the upper positioning clamping rod 3021.

[0041] When the valve body is placed on the movable support plate 2, both sides of the sliding ring 3 are in contact with the higher section of the fixed pressure rod 1002. As the bearing support 103 moves along the guide box 1 toward the direction close to the drilling bracket 102, the sliding ring 3 will gradually move to the lower section of the fixed pressure rod 1002. At this time, the sliding ring 3 will be pushed by the fixed pressure rod 1002 and move downward along the lower rotating shaft 301. At this time, the supporting spring 304 is compressed, and the connecting ring 303 moves downward along the upper rotating shaft 302. In the process of the sliding ring 3 moving downward along the lower rotating shaft 301, the sliding ring 3 is driven to rotate clockwise by the arc groove 305 outside the lower rotating shaft 301, and the lower positioning clamping rod 3011 rotates clockwise with the lower rotating shaft 301. When the connecting ring 303 descends, it will be driven to rotate counterclockwise by the arc groove 305 outside the upper rotating shaft 302. The upper positioning clamping rod 3021 rotates counterclockwise with the upper rotating shaft 302, and the lower positioning clamping rod 3011 rotates clockwise. When the upper and lower locating clamp rods 3021 rotate clockwise and counterclockwise, they will contact the valve body on the movable support plate 2, and the simultaneous movement of multiple lower locating clamp rods 3011 and multiple upper locating clamp rods 3021 can push the movable support plate 2 to move in the bearing support 103 through the valve body to adjust the valve body to the center position in the bearing support 103. After the drilling is completed, the bearing support 103 moves and resets. When the sliding ring 3 moves to a higher section of the fixed pressure rod 1002, the supporting spring 304 will push the sliding ring 3 to rise and reset along the lower rotating shaft 301, and the connecting rod will rise and reset accordingly. During this process, the lower rotating shaft 301 and the lower positioning clamp rod 3011 will rotate counterclockwise to reset, and the upper rotating shaft 302 and the upper positioning clamp rod 3021 will rotate clockwise to reset. At this time, under the action of the return spring 201 and the centering spring 203, the sliding block 202 and the movable support plate 2 move and reset, and the movable support plate 2 moves to the center position in the bearing support 103 again.

[0042] Embodiment 3: Based on embodiment 2, Figure 5 As shown, it also includes a rising adjustment mechanism for adjusting the position of the valve body, the rising adjustment mechanism includes a moving rack 4, a rotating shaft 401, a transmission gear 402, a cam 403 and a lifting and adjusting support plate 404. A moving rack 4 is fixedly connected to the bottom of the sliding connecting frame 109, and the moving rack 4 moves with the sliding connecting frame 109. A rotating shaft 401 is rotatably connected in the guide box 1, and a transmission gear 402 is fixed on the rotating shaft 401. The moving rack 4 can mesh with the transmission gear 402, and a cam 403 is fixed on the rotating shaft 401. When the moving rack 4 meshes with the transmission gear 402, the moving rack 4 drives the rotating shaft 401 and the cam 403 to rotate through the transmission gear 402. A lifting and adjusting support plate 404 is slidably connected in the guide box 1, and the top of the lifting and adjusting support plate 404 is V-shaped. When the lifting and adjusting support plate 404 rises to the highest point, the state of the valve body can be adjusted so that the central axis of the valve body completely coincides with the drill bit 1011.

[0043] As the sliding connecting frame 109 approaches the drilling bracket 102 along the guide rod 108, the moving rack 4 moves accordingly. During the movement, the moving rack 4 will contact the transmission gear 402 and drive it to rotate. The transmission gear 402 will drive the cam 403 to rotate through the rotating shaft 401. When the sliding connecting frame 109 contacts the inner wall of the guide box 1, the moving rack 4 just drives the rotating shaft 401 and the cam 403 to rotate 180 degrees through the transmission gear 402. During the rotation of the cam 403, the lifting and adjusting support plate 404 will be pushed to slide upward. During the rising process of the lifting and adjusting support plate 404, it will contact the parts extending outward on both sides of the valve body and adjust the valve body, adjust the angle between the side wall of the valve body and the drill bit 1011, and adjust the valve body to a state perpendicular to the drill bit 1011 so that the through holes drilled by the two drill bits 1011 can be connected.

The connecting pipe 501 is fixedly connected to the outside of the oil storage cylinder 5, and the connecting pipe 501 is communicated with the oil storage cylinder 5. The fixed frame 104 provides support for the connecting pipe 501 through a support, and the connecting plate 502 is fixedly connected to the mobile seat 101. The mobile piston 503 is slidably connected in the connecting pipe 501, and the mobile piston 503 is slidably connected to the connecting plate 502. A fixing ring is provided in the middle of the mobile piston 503. A second buffer spring 504 is provided between the connecting plate 502 and the fixed ring in the middle of the movable piston 503, one end of the second buffer spring 504 is fixed on the fixed ring in the middle of the movable piston 503, and the other end is fixed on the connecting plate 502, a lifting frame 505 is slidably connected to the fixed frame 104, the top of the lifting frame 505 is slidably arranged in the oil storage cylinder 5, a supporting spring 506 is provided between the lifting frame 505 and the fixed frame 104, the top of the supporting spring 506 is fixedly connected to the lifting frame 505, and the bottom of the supporting spring 506 is fixed to the fixed frame 104, a sliding clamping plate 507 is slidably connected to the lifting frame 505, a clamping spring 508 is provided between the sliding clamping plate 507 and the lifting frame 505, one end of the clamping spring 508 is fixed on the sliding clamping plate 507, and the other end is fixed on the lifting frame 505.

[0045] When the movable seat 101 moves toward the valve body, the movable seat 101 will push the second buffer spring 504 and the movable piston 503 to slide along the connecting pipe 501 through the connecting plate 502. At this time, the movable piston 503 will push the hydraulic oil in the connecting pipe 501 into the oil storage cylinder 5 to push the lifting frame 505 in the oil storage cylinder 5 downward and compress the supporting spring 506, and the sliding clamping plate 507 will drop accordingly. As the movable seat 101 continues to move, the sliding clamping plate 507 will contact the top surface of the valve body and press it onto the movable support plate 2. When the lifting frame 505 descends, it will cooperate with the lifting and adjusting support plate 404 to clamp the two ends of the valve body. When the drill bit 1011 contacts the valve body, as the movable seat 101 continues to move, the connecting plate 502 and the second buffer spring 504 outside the movable piston 503 will be compressed, and the lifting frame 50 5 and the pressing spring 508 between the sliding pressing plate 507 is also compressed to press the valve body against the movable support plate 2 during the drilling process. After the drilling is completed, the two movable seats 101 move away from each other and move the drill bit 1011 out of the valve body. During this process, the connecting plate 502 moves the movable piston 503 out of the connecting pipe 501. At this time, the hydraulic oil in the oil storage cylinder 5 is pumped into the connecting pipe 501. Under the push of the supporting spring 506, the lifting frame 505 will be pushed to slide upward along the oil storage cylinder 5 to reset, and the sliding pressing plate 507 and the pressing spring 508 will rise and reset accordingly. When the movable seat 101 moves and resets, the connecting plate 502, the movable piston 503, the second buffer spring 504, the lifting frame 505, the supporting spring 506, the sliding pressing plate 507 and the pressing spring 508 will return to their original state accordingly.

[0046] like Figure 6 and Figure 7 As shown, it also includes a support component for preventing the lifting and positioning support plate 404 from falling due to vibration. The support component includes a lifting wedge rod 6, a wedge-shaped slider 601 and a return spring 602. The lifting wedge rod 6 is fixedly connected to the lifting frame 505. The bottom of the lifting wedge rod 6 is an inclined surface. The wedge-shaped slider 601 is slidably connected to the outside of the guide box 1. The wedge slider 601 is L-shaped, and the top of the wedge slider 601 is an inclined surface. The lifting wedge rod 6 cooperates with the wedge slider 601. A return spring 602 is provided between the wedge slider 601 and the guide box 1. One end of the return spring 602 is fixed to the wedge slider 601, and the other end is fixed to the guide box 1.

[0047] When the lifting frame 505 descends, it will drive the lifting wedge rod 6 to descend. At this time, the lifting and positioning support plate 404 has risen to the highest point and adjusted the position of the valve body. When the lifting wedge rod 6 descends, it will contact the wedge slider 601. As the lifting frame 505 continues to descend, the lifting wedge rod 6 pushes the wedge slider 601 to slide along the guide box 1 and compresses the reset spring 602. The wedge slider 601 is pushed to the bottom of the lifting and positioning support plate 404 by the lifting wedge rod 6. At this time, the wedge slider 601 provides support for the lifting and positioning support plate 404. After the drilling is completed, the lifting frame 505 rises first and drives the lifting wedge rod 6 to rise. Under the push of the reset spring 602, the wedge slider 601 slides outward along the guide box 1 and moves away from the bottom of the lifting and positioning support plate 404. At this time, the lifting and positioning support plate 404 is no longer supported by the wedge slider 601.

[0048] like Figure 8-Figure 11 As shown, it also includes a flushing mechanism for cleaning residual debris in the valve body, the flushing mechanism includes a water storage frame 7, a water storage cylinder 702, a nozzle 703, a lifting assembly and a descending water spray assembly, the fixed frame 104 is slidably connected to the water storage frame 7, the water storage frame 7 is provided with a water inlet hole, and a one-way valve is installed in the water inlet hole at the top of the water storage frame 7, the water storage cylinder 702 is fixedly connected to the water storage frame 7, the water storage cylinder 702 is connected to the inside of the water storage frame 7, and a nozzle 703 is installed at the outlet of the water storage cylinder 702, the lifting assembly is installed on the drilling bracket 102, the lifting assembly is used to push the water storage frame 7 to rise, the descending water spray assembly is installed in the water storage frame 7, and when the water storage frame 7 descends, the descending water spray assembly can make the water in the water storage frame 7 spray outward.

[0049] like Fig. 9 and Fig.10 As shown, the lifting assembly includes a moving push block 1012, a first buffer spring 1013, a swing rod 701 and a cylindrical rod 704. The moving push block 1012 is slidably connected to the moving seat 101. A first buffer spring 1013 is provided between the moving push block 1012 and the moving seat 101. One end of the first buffer spring 1013 is fixed to the moving push block 1012, and the other end is fixed to the moving seat 101. The swing rod 701 is rotatably connected to the drilling bracket 102. A straight hole is provided on the top of the swing rod 701. A cylindrical rod 704 is fixed to the water storage frame 7. The cylindrical rod 704 passes through the straight hole on the swing rod 701 and is slidably connected thereto.

[0050] When the movable seat 101 moves toward the valve body to drill a hole, the movable push block 1012 will push the swing rod 701 to swing upward, thereby pushing the water storage frame 7 to rise along the fixed frame 104. During this process, the external water flows through the one-way valve in the top entrance of the water storage frame 7 and enters its interior. When the water storage frame 7 rises to the highest point, the water storage frame 7 and the water storage cylinder 702 are already full of water. The movable seat 101 continues to drive the drill rod to move and drill a hole on the valve body. The movable push block 1012 will slide relative to the movable seat 101 and compress the first buffer spring 1013. After the drilling is completed, the movable seat 101 moves and resets. When the first buffer spring 1013 returns to its original state, the movable push block 1012 will move with the movable seat 101. At this time, under the influence of gravity, the water storage frame 7 will slide downward along the fixed bracket to reset. When the water storage frame 7 drops to the lowest point, under the action of the descending water spraying assembly, the water in the water storage frame 7 and the water storage cylinder 702 will be sprayed outward along the nozzle 703.

[0051] like Fig.10 and Fig.11 As shown, the descending water spray assembly includes a lifting piston 705, a fixed plate 706, a water spray spring 707, a U-shaped fixed rod 8, a rotating baffle 801, a blocking shaft 802, a U-shaped sliding rod 803 and a pushing spring 804. The lifting piston 705 is slidably connected in the water storage cylinder 702, and the lifting piston 705 passes through the drilling bracket 102 and is slidably connected thereto. The lifting piston 705 is fixedly connected to the fixing plate 706, and a water spray spring 707 is arranged between the fixing plate 706 and the drilling bracket 102. One end of the water spray spring 707 is fixed to the fixing plate 706, and the other end is fixed to the drilling bracket 102. The U-shaped fixing rod 8 is fixedly connected to the water storage frame 7, and the U-shaped sliding rod 803 is slidably connected to the U-shaped fixing rod 8. 03 and the U-shaped fixed rod 8 are provided with a pushing spring 804, one end of the pushing spring 804 is fixed on the U-shaped fixed rod 8, and the other end is fixed on the U-shaped sliding rod 803. A blocking shaft 802 is rotatably connected in the water storage frame 7, and the blocking shaft 802 passes through the U-shaped fixed rod 8 and is rotatably connected with the U-shaped sliding rod 803. An inclined sliding groove is provided at the bottom of the blocking shaft 802, and the inclined sliding groove at the bottom of the blocking shaft 802 cooperates with the U-shaped sliding rod 803. A rotating baffle 801 is rotatably connected in the water storage frame 7, and the rotating baffle 801 is fixedly connected to the blocking shaft 802. When the U-shaped sliding rod 803 rises along the U-shaped fixed rod 8, it can drive the rotating baffle 801 to rotate through the blocking shaft 802 to connect the inside of the water storage frame 7 with the nozzle 703.

[0052] During the rising process of the water storage frame 7, the U-shaped fixed rod 8 rises accordingly. Under the push of the push spring 804, the U-shaped sliding rod 803 will slide downward along the U-shaped fixed rod 8. The falling of the U-shaped sliding rod 803 will drive it to rotate through the inclined slide groove outside the blocking shaft 802, and the rotating baffle 801 will rotate accordingly to close the channel between the water storage frame 7 and the nozzle 703; during the rising process of the water storage frame 7, the water spray spring 707 first returns to its original state, and during this process, the lifting and lowering inside the water storage cylinder 702 The piston 705 will rise accordingly. When the water spray spring 707 is restored, the lifting piston 705 will no longer rise with the water storage cylinder 702. At this time, the external water enters the water storage frame 7 through the top inlet and finally flows into the water storage cylinder 702. When the water storage frame 7 rises to the highest point, the lifting piston 705 just drops to the lowest point of the water storage cylinder 702. The water storage frame 7 and the water storage cylinder 702 are full of water. When the water storage frame 7 and the water storage cylinder 702 are lowered, the water storage frame 7 and the spray head 703 are at a certain distance from each other. The water in the water storage frame 7 and the water storage cylinder 702 will not be sprayed outwards. At this time, the lifting piston 705 and the fixed plate 706 will descend with the water storage cylinder 702 and compress the water spray spring 707. When the U-shaped sliding rod 803 contacts the drilling bracket 102, as the water storage frame 7 continues to descend, the U-shaped sliding rod 803 will slide upward along the U-shaped fixed rod 8 and compress the push spring 804. When the U-shaped sliding rod 803 rises, it will pass through the outside of the blocking shaft 802. The inclined slide groove drives it to rotate, and when the blocking shaft 802 rotates, it will drive the rotating baffle 801 to rotate. At this time, the through hole between the water storage frame 7 and the nozzle 703 is no longer blocked. At this time, the nozzle 703 is aligned with the through hole on the valve body, and the water spray spring 707 will quickly push the lifting piston 705 to rise along the water storage cylinder 702, so that the water in the water storage cylinder 702 is sprayed out through the water storage frame 7 and the nozzle 703. The water sprayed from the nozzle 703 will flush out the debris remaining in the through hole of the valve body.
