Description

Technical Field

[0001] This application relates to the field of drilling technology, specifically to a drilling device for processing pipe force valves. Background Technology

[0002] A pipe force valve is a control element used in hydraulic systems, primarily for regulating and controlling the direction, flow rate, and pressure of fluid flow. During the manufacturing process of pipe force valves, multiple holes are typically drilled into the valve for ease of installation.

[0003] The structure of a pipe-operated valve requires inclined and vertical branches connected to the circumferential sidewalls of the valve body, and holes need to be drilled at the ends of both branches. Some manufacturers, due to the large diameter of the pipe-operated valve, often hoist the valve and position the inclined branch end horizontally upwards when drilling holes at the inclined branch end. However, to adjust the valve to this horizontal position, repeated hoisting and adjustment are necessary, which is cumbersome. Referring to Chinese patent document CN217858885U, entitled "A Drilling Device for Valve Processing," this patent features a drilling machine mounted on the top of a processing table, a semi-circular tube on the processing table, an arc-shaped groove for placing workpieces inside the semi-circular tube, fixing mechanisms for securing workpieces at both ends of the outer side of the semi-circular tube, and an adjustment mechanism for adjusting the angle of the semi-circular tube at one end. During operation, the fixing mechanism secures the workpiece inside the semi-circular tube, while the adjusting mechanism allows the tube to rotate, enabling the drilling machine to drill holes on the side of the workpiece more effectively.

[0004] Referring to the above technical solution, the above solution can only process the hole at the end of the vertical branch pipe that is perpendicular to the circumferential side wall of the pipe force valve, but cannot process the hole at the end of the inclined branch pipe. It is still necessary to use the method of repeatedly lifting and adjusting the pipe force valve to process the hole at the end of the inclined branch pipe, which is cumbersome. Summary of the Invention

[0005] To reduce operational hassle and facilitate the machining of holes at the ends of inclined branch pipes, this application provides a drilling device for machining pipe force valves.

[0006] This application provides a drilling device for processing a pipe force valve, which adopts the following technical solution: a frame and a supporting circular plate. A horizontal frame is hinged to the right end of the frame, and a vertical frame is connected to the right end of the horizontal frame. A linear actuator is hinged to the left side of the frame. The telescopic end of the linear actuator is hinged to the bottom of the horizontal frame. A U-shaped groove is provided on the horizontal frame. The supporting circular plate has a positioning hole one that matches the flange hole of the pipe force valve. A frustum with a semi-circular arc groove of the U-shaped groove is fixedly connected to the bottom of the supporting circular plate. A positioning hole two is provided on the vertical frame, and a positioning pin is slidably connected in the positioning hole two. During operation, the supporting circular plate is first coaxially installed on the flange surface of the pipe force valve, and then the pipe force valve is hoisted onto the horizontal frame, and the frustum at the bottom of the supporting circular plate is inserted into the semi-circular arc groove of the U-shaped groove. A rotating mechanism for driving the supporting circular plate to rotate is provided on the horizontal frame. When it is necessary to process the inclined branch end hole on the pipe force valve, the inner end of the positioning pin can pass through the positioning hole two and cooperate with the inner hole of the vertical branch on the pipe force valve.

[0007] By adopting the above technical solution, the arc at the end of the U-shaped groove limits the position of the pipe force valve in the left and right directions, and the positioning pin limits the circumferential position of the pipe force valve, so that the inclined branch pipe is kept in the middle position of the left end of the pipe force valve. This allows the support frame to be rotated around the hinge by the linear actuator, and the end of the pipe force valve can be horizontally upward. The whole process does not require repeated lifting and adjustment of the pipe force valve, which is convenient to operate and helps to improve work efficiency.

[0008] Optionally, the vertical frame is provided with multiple support members, all of which can abut against the pipe force valve.

[0009] By adopting the above technical solution, the support components can be conveniently used to support the pipe force valve, which can not only improve the stability of the pipe force valve, but also reduce the local stress on the support frame, thus helping to improve the service life of the support frame.

[0010] Optionally, the support member is a rotating roller, and the rotating roller is rotatably connected to the vertical frame.

[0011] By adopting the above technical solution, the setting of the support component as a rotating roller can reduce the frictional force during the rotation of the pipe valve.

[0012] Optionally, a locking pin is slidably connected to the positioning pin, and a spiral groove that can cooperate with the locking pin is opened on the inner wall of the second positioning hole near the horizontal plate. An inclined hole that can cooperate with the locking pin is opened at the inner end of the spiral groove. The inclined hole is inclined from the outside of the vertical frame to the inside of the vertical frame.

[0013] By adopting the above technical solution, when it is necessary to process the inner hole of the inclined branch end of the pipe force valve, the positioning pin is rotated, the locking pin slides along the spiral groove, and then the positioning pin cooperates with the inner hole of the vertical branch on the pipe force valve, the locking pin enters the inclined groove, the position of the positioning pin is limited, reducing the risk of the pipe force valve rotating due to the positioning pin falling off, which is conducive to ensuring the drilling effect of the pipe force valve. During the process of machining the inclined branch pipe and rotating the crossbar to a vertical position, the locking pin can move out of the inclined hole under the action of gravity. The locking pin can then release the locking of the positioning pin. Under the action of gravity, the positioning pin slides along the spiral groove and drives the positioning pin to rotate. The positioning pin moves out of the inner hole of the vertical branch pipe on the pipe force valve, which facilitates the machining of the end hole of the vertical branch pipe on the rotating pipe force valve.

[0014] Optionally, a plurality of first support blocks are evenly fixed to the outer end of the positioning pin, and a plurality of second support blocks are fixedly connected to the vertical frame. The area between adjacent second support blocks is a clearance groove. When the locking pin moves to the inner end of the spiral groove, each first support block is located in a clearance groove. When the locking pin moves to the outer end of the spiral groove, each first support block moves out of the clearance groove and faces a second support block. A moving groove is provided on the inner wall of the second positioning hole, and the moving groove can communicate with the spiral groove.

[0015] By adopting the above technical solution, when the horizontal frame rotates to the vertical position, the positioning pin is blocked by the ground, the locking column moves upward along the moving groove and drives the positioning pin to move upward relative to the vertical frame, and the first support block and the second support block abut against each other, thereby reducing the impact of the force applied by subsequent drilling on the support frame.

[0016] Optionally, the inner end sidewall of the positioning pin is inclined and the tip is hemispherical.

[0017] By adopting the above technical solution, the side wall and tip of the positioning pin have a guiding function, which facilitates the positioning pin entering the vertical branch pipe of the pipe force valve.

[0018] Optionally, the cross frame consists of a cross plate and mounting seats fixedly connected to the left and right sides of the bottom of the cross plate, respectively. The telescopic end of the linear drive is hinged to the left mounting seat, and the right mounting seat is hinged to the right end of the frame through a hinge shaft.

[0019] By adopting the above technical solution, the mounting base can avoid interference between the support frame and the machine frame when the support frame rotates.

[0020] Optionally, the rotating mechanism includes a drive rod rotatably connected to the crossbeam, and the center of the drive rod coincides with the center of the semi-circular arc groove of the U-shaped groove. The drive rod can rotate around its own center under the drive of the rotation drive source. A sector block is fixedly connected to the end of the drive rod, and a sector groove that can cooperate with the sector block is opened at the bottom of the frustum.

[0021] By adopting the above technical solution, when the rotary drive source drives the drive rod to rotate, the sector block can drive the support circular plate and the pipe force valve placed on the support circular plate to rotate synchronously through the cooperation of the sector slot. In addition, the cooperation between the sector block and the sector slot can guide the movement of the support circular plate and facilitate the driving of the support circular plate.

[0022] In summary, compared with the prior art, this application includes the following beneficial technical effects: 1. This application positions the pipe force valve in the left and right directions and in the circumferential direction to keep the inclined branch pipe on the pipe force valve in the middle position on the left side. This makes it convenient for the end of the inclined branch pipe on the pipe force valve to be directly horizontal and upward when the linear actuator drives the support frame to rotate. This reduces the trouble of repeatedly lifting and adjusting the pipe force valve, making the operation convenient and improving work efficiency.

[0023] 2. The combination of sector blocks and sector grooves can not only facilitate the rotation of the support circular plate and the pipe force valve around their own axis, but also guide the support circular plate as it moves along the crossbeam.

[0024] 3. The rotating roller supports the pipe force valve, which not only improves the stability of the pipe force valve, reduces the local stress on the support frame, and extends the service life of the support frame, but also reduces the friction during the rotation of the pipe force valve.

[0029] Among them, reference Figure 2 , Figure 4 and Figure 5 The supporting circular plate 3 is used to place the pipe force valve 8. The supporting circular plate 3 has positioning holes 32 that match the flange holes of the pipe force valve 8. Each positioning hole 32 and the flange hole at the end of the pipe force valve 8 are connected by a bolt. A frustum 31 is fixedly connected to the bottom of the supporting circular plate 3 on the same axis. A U-shaped groove 211 is provided on the cross frame 21. The frustum 31 can cooperate with the semi-circular groove of the U-shaped groove 211. During operation, the supporting circular plate 3 is first coaxially installed on the flange surface of the pipe force valve 8, and then the pipe force valve 8 is hoisted onto the cross frame 21, and the frustum 31 at the bottom of the supporting circular plate 3 is inserted into the semi-circular groove of the U-shaped groove 211. Among them, reference Figure 2 , Figure 4 and Figure 5 The top of the vertical frame 22 is provided with two support members 7, which are rotating rollers. The rotating rollers are rotatably connected to the vertical frame 22 and can abut against the circumferential side wall of the pipe force valve 8. The rotating mechanism 4 is provided on the horizontal frame 21, and the rotating mechanism 4 is used to drive the supporting circular plate 3 to rotate around its own central axis when the frustum 31 and the U-shaped groove 211 semi-circular arc groove are engaged. The clamping mechanism is provided on the vertical frame 22, and it is used to clamp the pipe force valve 8 when it is necessary to process the end hole of the inclined branch pipe 82 on the pipe force valve 8.

[0030] Reference Figure 2 and Figure 4 The rotating mechanism 4 includes a drive rod 41, a rotary drive source, a sector block 42, and a sector groove 311. The drive rod 41 is rotatably connected to the cross frame 21, and its center coincides with the center of the semi-circular arc groove of the U-shaped groove 211. The rotary drive source can drive the drive rod 41 to rotate around its own central axis. The rotary drive source can be a motor, etc. The sector block 42 is fixedly connected to the end of the drive rod 41. The sector groove 311 is opened at the bottom of the support circular plate 3 and can cooperate with the sector block 42. When the support circular plate 3 is not placed, the sector block 42 is located on the right side.

[0031] When the force valve 8 needs to be rotated, the rotary drive source drives the drive rod 41 to rotate, the drive rod 41 rotates and drives the sector block 42 to rotate, and the sector block 42, through cooperation with the sector groove 311, drives the support circular plate 3 and the force valve 8 to rotate synchronously.

[0032] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 The clamping mechanism includes a positioning pin 5, a second positioning hole 221, a locking post 51, a spiral groove 222, and an oblique hole 223. The second positioning hole 221 is located on the vertical frame 22. The inner end of the positioning pin 5 is inclined and its tip is hemispherical. When it is necessary to process the end hole of the inclined branch pipe 82 on the pipe force valve 8, the inner end of the positioning pin 5 can slide through the second positioning hole 221 and cooperate with the inner hole of the vertical branch pipe 81 on the pipe force valve 8. The locking post 51 is slidably connected in the positioning pin 5. The spiral groove 222 is located on the inner wall of the second positioning hole 221 near the horizontal plate 212 and can cooperate with the locking post 51. The oblique hole 223 is located at the inner end of the spiral groove 222 and can cooperate with the locking post 51. The oblique hole 223 is inclined from the outside of the vertical frame 22 to the inside of the vertical frame 22.

[0033] When drilling the pipe force valve 8, first place the pipe force valve 8 on the support circular plate 3, then place the support circular plate 3 on the support frame 2 with the sector groove 311 on the support circular plate 3 facing inwards towards the U-shaped groove 211, and push the support circular plate 3 to slide along the U-shaped groove 211. The sector block 42 and the sector groove 311 cooperate, and then the support circular plate 3 abuts against the arc end of the U-shaped groove 211. At the same time, the pipe force valve 8 abuts against the rotating roller. Then, the drive rod 41 drives the sector block 42 to rotate. The rotation of block 42 drives the support plate 3 and the pipe valve 8 to rotate. The vertical branch pipe 81 on the pipe valve 8 is aligned with the positioning hole 221. The positioning pin 5 is rotated, and the locking pin 51 slides along the spiral groove 222. Then the positioning pin 5 cooperates with the inner hole of the vertical branch pipe 81 on the pipe valve 8 and locks the pipe valve 8. The locking pin 51 enters the inclined hole 223, and the position of the positioning pin 5 is fixed. Then the linear actuator 6 pushes the support frame 2 to rotate around the hinge. The end of the inclined branch pipe 82 on the pipe valve 8 is horizontally upward.

[0034] After drilling the end of the inclined branch pipe 82 on the pipe force valve 8, the linear actuator 6 continues to push the support frame 2 to rotate around the hinge. Then the horizontal plate 212 on the support frame 2 rotates to a vertical position. During this rotation, the locking pin 51 moves out of the inclined hole 223 under the action of gravity, and the positioning pin 5 is unlocked. Under the action of the gravity of the positioning pin 5, the locking pin 51 slides along the spiral groove 222, and the positioning pin 5 moves out of the inner hole of the vertical branch pipe 81 on the pipe force valve 8. Then the drive rod 41 rotates to drive the pipe force valve 8 to rotate, and the vertical branch pipe 81 on the pipe force valve 8 rotates to the top. At this time, the end of the vertical branch pipe 81 is horizontal and facing upward.

[0035] Reference Figure 5 and Figure 6 A drilling device for processing a pipe force valve further includes a first support block 52, a second support block 224, and a moving groove 226. Multiple first support blocks 52 are evenly and fixedly connected to the outer end of a positioning pin 5. Multiple second support blocks 224 are evenly and fixedly connected to a vertical frame 22, with an clearance groove 225 between adjacent second support blocks 224. The moving groove 226 is formed on the inner wall of the positioning hole 221 and can communicate with a spiral groove 222. When the locking pin 51 moves to the inner end of the spiral groove 222, each first support block 52 is located within a clearance groove 225. Figures 7 to 9 When the locking pin 51 moves to the outer end of the spiral groove 222, each first support block 52 moves out of the clearance groove 225 and faces a second support block 224. When the cross frame 21 rotates to the vertical state, the positioning pin 5 contacts the ground and the first support block 52 abuts against the second support block 224.

[0036] When the horizontal frame 21 rotates to the vertical position, the positioning pin 5 is blocked by the ground, the locking post 51 moves upward along the moving groove 226 and drives the positioning pin 5 to move upward relative to the vertical frame 22, and the first support block 52 and the second support block 224 abut together, thereby reducing the impact of the force applied by subsequent drilling on the support frame 2.

[0037] The implementation principle of the drilling device for processing a pipe force valve according to an embodiment of this application is as follows: When drilling the pipe force valve 8, first install the pipe force valve 8 on the support circular plate 3. Then, place the support circular plate 3 on the support frame 2 with the sector groove 311 on the support circular plate 3 facing inwards towards the U-shaped groove 211. Push the support circular plate 3 to slide along the U-shaped groove 211, and the sector block 42 engages with the sector groove 311. Then, the support circular plate 3 engages with the semi-circular groove of the U-shaped groove 211, and the pipe force valve 8 abuts against the rotating roller. Then, the drive rod 41 rotates, causing the sector block 42 to rotate. The rotation of the sector block 42 causes the support circular plate 3 and the pipe force valve to move together. 8. Rotate, the vertical branch pipe 81 on the pipe force valve 8 aligns with the positioning hole 221, rotate the positioning pin 5, the locking pin 51 slides along the spiral groove 222, then the positioning pin 5 engages with the inner hole of the vertical branch pipe 81 on the pipe force valve 8 and locks the pipe force valve 8, the locking pin 51 enters the inclined hole 223 and fixes the positioning pin 5. During this process, each first support block 52 enters a relief groove 225, then the linear actuator 6 pushes the support frame 2 to rotate around the hinge, the end of the inclined branch pipe 82 on the pipe force valve 8 is horizontally upward and the hole is completed.

[0038] After drilling the end of the inclined branch pipe 82 on the pipe force valve 8, the linear actuator 6 continues to push the support frame 2 to rotate around the hinge. Then the horizontal plate 212 on the support frame 2 rotates to a vertical position. During this rotation, the locking pin 51 moves out of the inclined hole 223 under the action of gravity, and the positioning pin 5 is unlocked. Under the action of gravity, the locking pin 51 slides along the spiral groove 222. The positioning pin 5 rotates and moves out of the inner hole of the vertical branch pipe 81 on the pipe force valve 8. Each first support block 52 moves out of the clearance groove 225 and is directly opposite a second support block 224. Then the positioning pin 5 moves upward due to the obstruction of the ground, and the locking pin 51 slides along the moving groove 226. After that, the first support block 52 and the second support block 224 abut and support the support frame 2. Then the drive rod 41 rotates and drives the pipe force valve 8 to rotate. The vertical branch pipe 81 on the pipe force valve 8 rotates to the top and the end of the vertical branch pipe 81 is horizontal and facing upward.
