Description

Technical Field

[0001] The present invention belongs to the field of safety valve processing, and particularly relates to an integrated processing device for safety valves. Background Art

[0002] As a key safety device, the safety valve is mainly used in high-pressure vessels and pipeline systems to prevent danger when the pressure exceeds the set value. Its basic structure consists of multiple important parts, among which the most critical ones include the valve body, valve cover, spring, valve seat, valve disc, etc. In order to ensure that the valve body can be firmly combined with the valve cover and flange and can withstand the working load in a high-pressure environment, these two parts are usually connected by bolts. This connection method can not only withstand a relatively high internal pressure but also facilitate operation when disassembly or maintenance is required.

[0003] Currently, in order to achieve a firm connection between the valve body and the valve cover and flange, blind holes usually need to be drilled on the connection surface between the valve body and the valve cover, and the blind holes need to be tapped to provide accurate and stable mounting holes for the connection bolts when connecting with the valve cover. Then, through holes need to be drilled on the connection surface between the valve body and the flange to facilitate subsequent connection with the flange. However, in the traditional processing method, this process is often divided into multiple independent steps. First, workers need to drill holes on the two connection surfaces of the valve body in the drilling area. After drilling, the valve body is usually transferred to the tapping area for tapping operations. This step-by-step processing method consumes time and labor during the transfer process of the valve body, and also makes the processing processes of each step independent of each other, resulting in an increase in the overall processing time of the safety valve and greatly reducing the processing efficiency of the valve body. Summary of the Invention

[0034] The following will further describe the present application in detail with reference to the appended Figures 1-12 drawings.

[0036] On the left side of the inner bottom end of the processing frame 1, two mounting plates 14 are fixedly arranged in a front-back symmetrical distribution. A position switching mechanism 15 is arranged between the two mounting plates 14. A three-jaw chuck 16 is arranged on one side of the position switching mechanism 15. A valve body 17 is placed on the right side of the three-jaw chuck 16.

[0037] During the process of drilling and tapping the valve body 17, first, the three-jaw chuck 16 is used to fix the valve body 17. Then, the first electric push rod 3 can be used to adjust the use positions of the drilling machine 10 and the tapping machine 11. Finally, the valve body 17 can be directly processed by drilling and tapping through the drilling machine 10 and the tapping machine 11.

[0038] Refer to Figure 5 、 Figure 6 and Figure 7 , the positioning mechanism 8 includes a second electric push rod 801 fixedly arranged on the first connecting block 7. A positioning rod 802 is fixedly arranged on the telescopic shaft of the second electric push rod 801. A pressure sensor 803 is fixedly arranged at one end of the positioning rod 802 away from the second electric push rod 801. A groove 804 is opened inside the positioning rod 802. A first spring 805 is fixedly arranged inside the groove 804. One end of the first spring 805 away from the first connecting block 7 is fixedly arranged with a slider 806. A first connecting rod 807 is fixedly arranged on one side of the slider 806 away from the first spring 805. A frustum 808 is fixedly arranged at one end of the first connecting rod 807 away from the slider 806. Three sliding openings 809 which are circumferentially distributed and communicated with the groove 804 are opened on the outer side of the positioning rod 802 near the lower side. A second connecting rod 810 is slidably arranged inside the sliding opening 809. One end of the second connecting rod 810 penetrates into the groove 804 and is connected with the outer side of the first connecting rod 807.

[0039] The positioning mechanism 8 further includes three wedge-shaped blocks 811 arranged inside the groove 804 and used in cooperation with the frustum 808. A third connecting rod 812 is fixedly arranged on one side of the wedge-shaped block 811 away from the first connecting block 7. A third spring 813 is sleeved on the outer side of the third connecting rod 812. Two ends of the third spring 813 are respectively connected with the wedge-shaped block 811 and the groove 804. Three arc-shaped grooves 814 which are circumferentially distributed are opened on the outer side of the positioning rod 802 near the upper side. An arc-shaped block 815 is arranged inside the arc-shaped groove 814. The third connecting rod 812 penetrates out of the groove 804 and is connected with one side of the arc-shaped block 815.

[0040] In order to ensure the accuracy of the drilling position during the process of drilling blind holes on the connection surface between the valve body 17 and the valve cover, after the valve body 17 is fixed on the three-jaw chuck 16, at this time, the connection surface between the valve body 17 and the valve cover is exactly facing the drilling machine 10. The second electric push rod 801 works to drive the positioning rod 802 to move, so that the distance between the positioning rod 802 and the valve body 17 is greater than the distance between the drill bit on the drilling machine 10 and the valve body 17. At this time, the first electric push rod 3 on the right side works to drive the drilling machine 10 to move to the left. When the drill bit on the drilling machine 10 contacts the valve body 17, the drilling machine 10 starts to work, so that the drilling machine 10 can perform blind hole drilling operations on the connection surface between the valve body 17 and the valve cover. During the process of the drilling machine 10 moving to the left, it will also drive the corresponding positioning rod 802 to move to the left. When the pressure sensor 803 on the positioning rod 802 contacts the right side of the valve body 17, the first electric push rod 3 stops working. At this time, the first group of drilling operations on the connection surface between the valve body 17 and the valve cover is completed. Then, start the first electric push rod 3 to work to drive the structure on it to move to the right until the drilling machine 10 just disengages from the valve body 17. Then, the rotating mechanism 4 can be used to drive the drilling machine 10 and the positioning rod 802 to rotate. After rotation, the positioning rod 802 is aligned with the holes drilled in the first group.

[0041] When performing the second group of drilling operations on the connection surface between the valve body 17 and the valve cover, the second electric push rod 801 works to drive the positioning rod 802 to move to the left, so that the distance between the positioning rod 802 and the valve body 17 is less than the distance between the drill bit on the drilling machine 10 and the valve body 17. Then, when the first electric push rod 3 works to drive the drilling machine 10 and the corresponding positioning rod 802 to move to the left, the positioning rod 802 will first be inserted into the drilled blind hole. Then, as the positioning rod 802 continues to move, the second connecting rod 810 will contact the right side of the valve body 17. When the positioning rod 802 continues to move, the second connecting rod 810 will drive the first connecting rod 807 to move. The movement of the first connecting rod 807 will drive the frustum 808 to move and squeeze the wedge block 811. After being squeezed, the wedge block 811 will push the arc block 815 out of the arc groove 814 through the third connecting rod 812, so that the arc block 815 abuts against the inner wall of the drilled blind hole. At this time, the drill bit on the drilling machine 10 contacts the right side of the valve body 17 and continues to perform the second group of drilling operations. After the pressure sensor 803 on the positioning rod 802 contacts the inner wall of the drilled blind hole, the drilling depth has not reached yet. At this time, the second electric push rod 801 works to drive the positioning rod 802 to slowly move in the drilled blind hole, and the pressure sensor 803 does not contact the inner wall of the drilled blind hole to avoid affecting the normal operation of the drilling machine 10. After drilling the second group of holes, repeat the above steps to complete the blind hole drilling work on the connection surface between the valve body 17 and the valve cover. During the drilling process, the cooperation of the positioning rod 802 and the arc block 815 can be used to position the drill bit on the drilling machine 10 to ensure the accuracy of the drilling position during the drilling process and further improve the stability during drilling.

[0042] See Figure 8 、 Figure 9 and Figure 12 The position switching mechanism 15 includes a rotating rod 151 rotatably arranged between the two mounting plates 14, a fixed block 152 is fixedly arranged on the outside of the rotating rod 151, and limiting holes 153 are provided on the bottom and left side of the fixed block 152. The right side of the fixed block 152 is connected to the left side of the three-jaw chuck 16, and a first motor 154 is fixedly arranged on one side of one of the mounting plates 14, and the output shaft of the first motor 154 is connected to one end of the rotating rod 151.

[0043] A base plate 18 is fixedly provided on the left side of the interior of the processing frame 1, and a limiting mechanism 19 is provided on the base plate 18 for use with the fixed block 152. The limiting mechanism 19 includes an annular electromagnet 191 fixedly provided at the bottom of the base plate 18, and a magnetic block 192 is magnetically adsorbed on the bottom end of the annular electromagnet 191. A limiting rod 193 is fixedly provided on the upper part of the magnetic block 192. The end of the limiting rod 193 away from the magnetic block 192 passes through the annular electromagnet 191 and is plugged into the corresponding limiting hole 153. Two T-shaped rods 194 symmetrically distributed front to back are fixedly provided at the bottom of the base plate 18, and the bottom end of the T-shaped rod 194 passes through the magnetic block 192 and is slidably connected to the magnetic block 192. A second spring 195 is sleeved on the outer side of the T-shaped rod 194, and the two ends of the second spring 195 are respectively connected to the magnetic block 192 and the base plate 18.

[0044] In order to facilitate the continued tapping of the drilled blind hole, after the blind hole is drilled on the connecting surface of the valve body 17 and the valve cover, the annular electromagnet 191 stops working. At this time, the adsorption force on the magnetic block 192 disappears, and then the magnetic block 192 can be driven to move downward under the elastic force of gravity and the second spring 195. The downward movement of the magnetic block 192 can drive the limit rod 193 to move downward and out of the corresponding limit hole 153. The action of the second spring 195 prevents the magnetic block 192 from completely separating from the bottom plate 18, thereby canceling the limit fixation of the fixed three-jaw chuck 16. Then the first motor 154 works to drive the rotating rod 151 rotates counterclockwise, and the counterclockwise rotation of the rotating rod 151 can drive the fixed block 152 to rotate counterclockwise. The rotation of the fixed block 152 drives the three-jaw chuck 16 to rotate ninety degrees counterclockwise so that it is in a horizontal position. At this time, the switching of the position of the valve body 17 is completed, so that the connection surface between the valve body 17 and the valve cover is located at the lower end of the tapping machine 11, and then the annular electromagnet 191 continues to work to magnetically adsorb the magnetic block 192. When the magnetic block 192 is adsorbed, it will move upward and drive the limit rod 193 to insert into the corresponding limit hole 153, so that the three-jaw chuck 16 can continue to be limited to ensure the stability of the tapping operation.

[0045] After switching the position of the valve body 17, tapping operations can be performed on the blind holes drilled on the valve body 17 according to the same steps as before drilling. This is not only convenient and fast, but also ensures the accuracy of the tapping position. After the tapping is completed, the connecting surface between the valve body 17 and the flange is exactly facing the drilling machine 10 at this time, and then the operation of drilling through holes on the connecting surface between the valve body 17 and the flange can be continued, which further improves the processing efficiency of the valve body 17.

[0046] Refer to Figure 1 、 Figure 10 and Figure 12 Refer to

[0047] In order to ensure that the drilling machine 10 can be aligned with the connecting surface between the valve body 17 and the flange after the three-jaw chuck 16 rotates, after the three-jaw chuck 16 rotates to drive the valve body 17 to rotate counterclockwise by ninety degrees, at this time, the cooperation of the electric sliding sleeve 13 and the slide rail can drive the cross plate 2 to move up and down. The upward movement of the cross plate 2 can drive the drilling machine 10 to move upward, so that the drilling machine 10 can be aligned with the connecting surface between the valve body 17 and the flange, which is convenient for subsequent operations of drilling through holes on the connecting surface between the valve body 17 and the flange.

[0048] Refer to Figure 1 and Figure 2 Refer to

[0049] The rotating mechanism 4 includes a connecting plate 401 fixedly arranged on the telescopic shaft of the first electric push rod 3. A rotating shaft 402 is rotatably arranged on the side of the connecting plate 401 away from the telescopic shaft of the first electric push rod 3. The side of the rotating shaft 402 away from the connecting plate 401 is connected to the disc 5. A second motor 403 is fixedly arranged on the side of the connecting plate 401 away from the rotating shaft 402. A gear 404 is fixedly arranged on the output shaft of the second motor 403 and on the outer side of the rotating shaft 402, and the two gears 404 are meshed with each other.

[0050] To facilitate the positioning rod 802 to accurately insert into the drilled holes according to the number of holes drilled on the valve body 17, after the first group of holes are drilled on the valve body 17, the second motor 403 operates to drive the rotating shaft 402 to rotate. The rotation of the rotating shaft 402 drives the disc 5 to rotate, and the rotation of the disc 5 drives the drilling machine 10 and the positioning rod 802 to rotate. When the position of the drilling machine 10 is adjusted, the worm 603 can be rotated at this time to drive the worm wheel 601 to rotate. The rotation of the worm wheel 601 can drive the positioning rod 802 to rotate so that it aligns with the drilled holes, so that the positioning rod 802 can accurately insert into the drilled holes when drilling the second group of holes, thereby ensuring the accuracy during the drilling operation. The operation is the same during the tapping operation, which also ensures the accuracy during the tapping operation.

[0051] Refer to Figure 3 and Figure 4 A stabilizing mechanism 20 is jointly provided between the corresponding two positioning rods 802. The stabilizing mechanism 20 includes a stabilizing ring 201 slidably disposed outside the positioning rod 802. A first stabilizing rod 202 is fixedly disposed between the two stabilizing rings 201. A round block 203 is rotatably disposed at one end of the disc 5 away from the rotating shaft 402. Two second stabilizing rods 204 are fixedly disposed on the outer side of the round block 203. One end of the second stabilizing rod 204 away from the round block 203 is connected to the stabilizing ring 201.

[0052] Refer to Figure 5 and Figure 11 Two guiding ports 21 are opened on the outer side of the positioning rod 802 near the stabilizing ring 201. Two guiding blocks 22 that cooperate with the guiding ports 21 are fixedly disposed on the inner side of the stabilizing ring 201. One side of the guiding block 22 away from the stabilizing ring 201 is inserted into the guiding port 21 and is slidably connected to the guiding port 21.

[0053] To further ensure the stability of the positioning rod 802 during the drilling and tapping processes, when the positioning rod 802 is inserted into the drilled holes and then the drilling or tapping operation continues, a stable triangular structure is formed by the cooperation of the stabilizing ring 201, the first stabilizing rod 202, and the second stabilizing rod 204, so as to effectively resist the vibration force during drilling and tapping, and thus ensure the stability of the positioning rod 802 during the drilling and tapping processes.

[0054] During specific operation, after the valve body 17 is fixed on the three-jaw chuck 16, the connection surface between the valve body 17 and the valve cover faces the drilling machine 10. At this time, the connection surface between the valve body 17 and the flange is close to the inner bottom end of the processing frame 1. Then, the cooperation of the rotating mechanism 4 and the drilling machine 10 can be used to perform the operation of drilling blind holes on the connection surface between the valve body 17 and the valve cover, and then the cooperation of the adjusting mechanism 6 and the positioning rod 802 can ensure the accuracy and stability during the process of drilling blind holes.

[0055] After drilling the blind hole on the connecting surface between the valve body 17 and the valve cover, the cooperation of the limiting mechanism 19 and the position switching mechanism 15 can drive the valve body 17 to rotate counterclockwise by 90 degrees. At this time, the connecting surface between the valve body 17 and the valve cover faces the tapping machine 11, while the connecting surface between the valve body 17 and the flange faces the drilling machine 10. Then, the tapping machine 11 can continue the tapping operation on the drilled blind hole. At this time, the accuracy and stability during the tapping operation are still maintained by the positioning rod 802.

[0056] After the tapping operation is completed, the deep hole drilling operation on the connecting surface between the valve body 17 and the flange can be continued according to the previous steps. Thus, during the processes of drilling blind holes, tapping, and deep hole drilling on the valve body 17, only one position transformation of the valve body 17 is required, greatly reducing the time waste caused by multiple position transformations of the valve body 17, and greatly improving the processing efficiency of the valve body 17.

[0057] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
