Description

Technical Field

[0001] This invention relates to the field of instrument valve assembly processing technology, and more specifically, to an instrument valve assembly connection hole processing device. Background Technology

[0002] An instrument valve manifold is a combination device used to control the direction, pressure, and flow rate of fluid in a pipeline. It mainly consists of valves, actuators, and pipe fittings, and is widely used in industrial production, construction, and energy fields. By combining different valves (such as gate valves and drain valves), it can realize the on / off of fluid, pressure balance, or flow regulation. For example, a two-valve manifold usually includes a gate valve and a drain valve to control the on / off of fluid and the discharge of pollutants; a three-valve manifold adds a balancing valve to achieve pressure balance on the high and low pressure sides.

[0003] For example, Chinese utility model patent CN212822859U discloses a device for processing connection holes of quay crane tie rods, including a base and a connecting block, with a fixed frame fixedly connected to the top of the base. This device uses a first servo motor to drive a gear to rotate, which in turn drives a moving block meshing with it in the opposite direction, thereby moving the drill rod in the opposite direction. This allows for adjustment of the distance between the drill rods, enabling the processing of connection holes at different distances. The device works by placing the tie rod to be processed between two fixed plates and clamping it. Then, a lead screw is inserted into the fixed hole, and a knob is turned. The knob rotates the lead screw, causing it to thread into a limit block, thus limiting the position of the fixed plate and preventing it from shifting during tie rod processing. This solves the problem of not being able to adjust the distance between the connection holes at both ends of the tie rod.

[0004] During the machining of instrument valve groups, especially when machining the internal threads of the instrument valve group connection holes, it is necessary to first use a drill bit on a drilling machine to drill the instrument valve group connection holes, and then replace the drill bit with a tap to tap the instrument valve group connection holes. Although existing drilling machines have a tool changing mechanism that can switch between drill bits and taps, the tool changing mechanism on the drilling machine requires the cooperation of a cylinder and a motor to operate. This not only increases the cost of use and is not conducive to the rapid development of small enterprises, but also affects the performance of the drilling machine. Summary of the Invention

[0015] As a further aspect of the present invention: the limiting groove is an arc-shaped structure, the center of the limiting groove is located on the axis of the rotating rod, and the arc of the limiting groove is 0-180 degrees.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention uses a tool changing assembly and a clamping mechanism to fix the instrument valve group on the worktable. The drilling machine body then uses a drill bit to drill the connection hole of the instrument valve group. After drilling, the servo motor is activated, causing its output shaft to rotate the threaded rod. Due to the sliding contact between the fixed block and the lower fixed part, the connecting rod is fixed in position, and the threaded rod is threadedly connected to the connecting rod. This causes the connecting rod to move the tool arm body upwards until the fixed block and the lower fixed part are no longer in contact. At this point, the connecting rod rotates the tool arm body 180 degrees, causing the fixed block to slide into contact with the vertical plate of the support frame until the tool arm body clamps the drill bit holder on the main spindle of the drilling machine body. Then, the servo motor is controlled to cause its output shaft to rotate the threaded rod in the opposite direction. Because the fixed block and the lower fixed part are in sliding contact, the connecting rod is fixed in position, and the threaded rod is threadedly connected to the connecting rod. This causes the connecting rod to move the tool arm body upwards until the fixed block and the lower fixed part are no longer in contact. At this point, the connecting rod rotates the tool arm body 180 degrees, causing the fixed block to slide into contact with the vertical plate of the support frame. This continues until the tool arm body clamps the drill bit holder on the main spindle of the drilling machine body. Finally, the servo motor is controlled to cause its output shaft to rotate the threaded rod in the opposite direction. The upper fixing part slides into contact, causing the connecting rod to move the cutter arm body downwards until the fixing block no longer contacts the upper fixing part. At this point, the connecting rod drives the cutter arm body to rotate 180 degrees, causing the fixing block to slide into contact with the vertical plate of the support frame. After the cutter arm body moves to the cutter disc position, the drill bit shank is placed inside the cutter disc, and the tap shank is clamped. Then, the servo motor is controlled to rotate in the same direction as before, until the cutter arm body fixes the tap shank on the main shaft of the drilling machine body. The tap on the drilling machine body can then be used to tap the connection hole of the instrument valve group. Compared with the prior art, the present invention has a reasonable structural design. With a single motor, lifting and tool changing operations can be realized simultaneously, which greatly reduces the cost of use and is conducive to the rapid development of small enterprises.

[0018] 2. This invention, by setting up a clamping mechanism, according to the required shape of the instrument valve assembly structure, uses a locking assembly to rotate the knob on the rotating rod, causing the rotating rod to rotate via the rotating shaft B and the connecting plate B. This causes the rotating disk to rotate within the rotating groove, causing the rotating frame to drive the clamping plate and the adapting plate to rotate until the rotating frame drives the clamping plate and the adapting plate to rotate 180 degrees. At this point, the conversion between the clamping plate and the adapting plate is completed. Subsequently, the position of the rotating rod is fixed by the locking assembly. Then, the instrument valve assembly is placed between the two support plates. By rotating the handwheel on the double-acting screw, the double-acting screw rotates via the rotating shaft A and the inner wall of the moving groove, causing the moving block to be threadedly connected to the double-acting screw. This allows the two moving blocks to slide relative to each other within the moving groove, causing the two support plates to move relative to each other until the clamping plate or the adapting plate contacts the surface of the instrument valve assembly, thus completing the clamping of the instrument valve assembly.

[0019] 3. This invention, by setting a locking component, allows the movable block to slide within the movable groove when pressed, causing the inner wall of the extrusion groove to press against the extrusion block. This causes the extrusion block to slide from the lower end to the upper end of the extrusion groove, and the sliding block to slide upwards within the sliding groove and locking groove until the extrusion block reaches the upper end of the extrusion groove. At this point, the sliding block moves out of the locking groove. Then, rotating the rotating rod causes it to rotate via the rotating shaft B and the connecting plate B, causing the rotating disk to rotate within the rotating groove. This causes the limiting block to slide from one inner wall of the limiting groove to the other inner wall, and the rotating frame to drive the clamping plate. The adapting plate rotates until the limiting block slides to the inner wall of the limiting groove on the other side. At this point, the conversion between the clamping plate and the adapting plate is completed. Then, the movable block is released, and under its own weight, the sliding block will slide downward in the sliding groove. Since the weight of the sliding block is greater than the weight of the movable block, the extrusion block will slide from the high end of the extrusion groove to the low end of the extrusion groove, causing the movable block to slide in the opposite direction in the movable groove until the extrusion block slides to its original position. At this point, the sliding block is inserted into the locking groove, fixing the position of the rotating disk in the rotating groove and making the position of the rotating rod more stable.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1 to 9As shown, the present invention provides a machining equipment for instrument valve assembly connection holes, including a drilling machine body 1, a clamping mechanism 2, and a tool changing assembly 3 for machining instrument valve assemblies; the drilling machine body 1 includes a machine body 101 and a worktable 102; the worktable 102 is fixed on the machine body 101 and is connected to the instrument valve assembly through the clamping mechanism 2; the tool changing assembly 3 is arranged on the machine body 101; the tool changing assembly 3 includes a support frame 301, a fixing plate 302, a servo motor 303, a fixing component 304, and a thread. Rod 305, connecting rod 306, cutter arm body 307, and fixing block 308; support frame 301 is fixed on the machine body 101; fixing plate 302 is fixed on the top surface of support frame 301; servo motor 303 is fixed on fixing plate 302 through motor base, and the output end of servo motor 303 extends to the outside through fixing plate 302; two fixing parts 304 are centrally symmetrically fixed on the vertical plate of support frame 301; threaded rod 305 is fixedly connected to the output end of servo motor 303; connecting rod 306 is screwed in. On the threaded rod 305; the cutter arm body 307 is fixedly connected to the end of the connecting rod 306, and the end of the cutter arm body 307 is provided with a tool holder clamping mechanism, which is the same as the tool holder clamping mechanism on the existing tool changing arm; the fixing block 308 is fixed on the circumferential surface of the connecting rod 306 and slides with the vertical plate of the support frame 301, and the fixing block 308 contacts the fixing member 304; the fixing member 304 has an L-shaped structure, and the distance between the two fixing members 304 is appropriate to the height of the fixing block 308. The distance between the fixing member 304 and the vertical plate of the support frame 301 is matched with the length of the fixing block 308 to facilitate contact between the fixing block 308 and the inner wall of the fixing member 304, guiding the threaded connection between the threaded rod 305 and the connecting rod 306, so that the connecting rod 306 can move. The cutter head is located below the cutter arm body 307, and the cutter shank inside the cutter head is located above the cutter head, which facilitates the clamping of the cutter arm body 307. At the same time, in order to save costs, the cutter arm body 307 is a single-end clamping device.

[0038] This invention utilizes a tool changing assembly 3 and a clamping mechanism 2 to fix the instrument valve assembly onto the worktable 102. The drilling machine body 1 then drills the connection hole of the instrument valve assembly using a drill bit. After drilling, the servo motor 303 is activated, causing its output shaft to rotate the threaded rod 305. Due to the sliding contact between the fixing block 308 and the lower fixing member 304, the connecting rod 306 is fixed, creating a threaded connection between the threaded rod 305 and the connecting rod 306. This causes the connecting rod 306 to move the tool arm body 307 upwards until the fixing block 308 and the lower fixing member 304 are no longer in contact. At this point, the connecting rod 306 rotates the tool arm body 307 180 degrees, causing the fixing block 308 to slide against the vertical plate of the support frame 301 until the tool arm body 307 clamps the drill bit holder on the main shaft of the drilling machine body 1. Finally, the servo motor 303 is controlled to rotate its output shaft in the opposite direction, causing the threaded rod 305 to rotate in the opposite direction. As the machine rotates, the fixed block 308 slides in contact with the upper fixed member 304, causing the connecting rod 306 to drive the cutter arm body 307 to move downwards until the fixed block 308 and the upper fixed member 304 are no longer in contact. At this time, the connecting rod 306 drives the cutter arm body 307 to rotate 180 degrees, causing the fixed block 308 to slide in contact with the vertical plate of the support frame 301. After the cutter arm body 307 moves to the cutter disc position, the drill bit shank is placed in the cutter disc and the tap shank is clamped. Then, the servo motor 303 is controlled to rotate in the same direction as before until the cutter arm body 307 fixes the tap shank on the main shaft of the drilling machine body 1. The tap on the drilling machine body 1 can then be used to tap the connection hole of the instrument valve group. Compared with the prior art, the present invention has a reasonable structural design. With a single motor, lifting and tool changing operations can be realized simultaneously, which greatly reduces the cost of use and is conducive to the rapid development of small enterprises.

[0039] In a preferred embodiment, the clamping mechanism 2 includes a moving component 4; the moving component 4 includes a moving groove 401, a bidirectional lead screw 402, a moving block 403, and a support plate 404; the moving groove 401 is provided on the top surface of the worktable 102; one end of the bidirectional lead screw 402 is rotatably connected to the inner wall of the moving groove 401 through a rotating shaft A, and the other end extends through the moving groove 401 to the outside; two moving blocks 403 are symmetrically slidably disposed in the moving groove 401, and the moving blocks 403 are threadedly connected to the bidirectional lead screw 402; the support plate 404 is fixedly connected to the moving blocks 403;

[0040] The clamping mechanism 2 also includes a conversion assembly 5; the conversion assembly 5 includes a connecting plate A501, a connecting plate B502, a through-hole groove 503, a rotating rod 504, a rotating frame 505, a clamping plate 506 for fixing the instrument valve group, and an adapting plate 507; the two connecting plates A501 and the two connecting plates B502 are fixed on the opposite surfaces of the two support plates 404; the connecting plate A501 has a through-hole groove 503; one end of the rotating rod 504 is connected to the connecting plate B502 via a rotating shaft B. 2. A rotating connection is made, with the other end extending to the outside through the through-hole groove 503 and connected to the connecting plate A501 via the locking assembly 6; a rotating frame 505 is sleeved on the rotating rod 504 and located between the connecting plate A501 and the connecting plate B502; a clamping plate 506 is arranged on the rotating frame 505; two adapting plates 507 are symmetrically sleeved on the rotating rod 504 and fixedly connected to the clamping plate 506; the adapting plates 507 have a V-shaped structure, and the tips of the two adapting plates 507 are arranged opposite each other.

[0041] This invention, by setting up a clamping mechanism 2, according to the required instrument valve group structure shape, uses a locking assembly 6 to rotate a knob on a rotating rod 504, causing the rotating rod 504 to rotate via a rotating shaft B and a connecting plate B502. This causes the rotating disk 602 to rotate within the rotating groove 601, which in turn causes the rotating frame 505 to drive the clamping plate 506 and the adapting plate 507 to rotate until the rotating frame 505 drives the clamping plate 506 and the adapting plate 507 to rotate 180 degrees. At this point, the conversion between the clamping plate 506 and the adapting plate 507 is completed. Subsequently... Then, the position of the rotating rod 504 is fixed by the locking assembly 6. Next, the instrument valve assembly is placed between the two support plates 404. By rotating the handwheel on the double-acting screw 402, the double-acting screw 402 rotates with the inner wall of the moving groove 401 through the rotating shaft A, so that the moving block 403 is threadedly connected to the double-acting screw 402, so that the two moving blocks 403 slide relative to each other in the moving groove 401, so that the two support plates 404 move relative to each other until the clamping plate 506 or the adapting plate 507 contacts the surface of the instrument valve assembly, thus completing the clamping of the instrument valve assembly.

[0042] In a preferred embodiment, the locking assembly 6 includes a rotating groove 601, a rotating disk 602, a sliding groove 603, a movable groove 604, a locking groove 605, a sliding block 606, a movable block 607, a pressing groove 608, a pressing block 609, a limiting groove 610, and a limiting block 611; the rotating groove 601 is provided in the through-hole groove 503; the rotating disk 602 is rotatably disposed in the rotating groove 601 and coaxially fixedly connected to the rotating rod 504; the sliding groove 603 is provided on the top wall of the rotating groove 601; the movable groove 604 is provided on the inner side wall of the sliding groove 603; two locking grooves 605 are arranged in a ring array on the circumferential surface of the rotating disk 602, and the opening of the locking groove 605 is provided with a chamfer; the sliding block 606 slides through the sliding groove 603 and is inserted into the locking groove 605; the movable block 606... 07 is slidably inserted into the movable slot 604; the movable block 607 has an extrusion slot 608; the extrusion block 609 is slidably inserted into the extrusion slot 608 and fixedly connected to the sliding block 606; the weight of the sliding block 606 is greater than the weight of the movable block 607; the extrusion slot 608 is an inclined structure, with its lower end close to the direction of the rotating frame 505 and its upper end away from the direction of the rotating frame 505; a limiting slot 610 is provided in the rotating slot 601; the limiting block 611 is slidably inserted into the limiting slot 610 and fixedly connected to the rotating disk 602; the limiting slot 610 is an arc-shaped structure, with its center on the axis of the rotating rod 504, and its arc is 0-180 degrees, to facilitate the restriction of the rotation of the rotating disk 602.

[0043] This invention, by setting a locking component 6, allows the movable block 607 to slide within the movable groove 604 when pressed, causing the inner wall of the extrusion groove 608 to press against the extrusion block 609. This causes the extrusion block 609 to slide from the lower end to the upper end of the extrusion groove 608, and the sliding block 606 to slide upwards within the sliding groove 603 and locking groove 605 until the extrusion block 609 reaches the upper end of the extrusion groove 608. At this point, the sliding block 606 moves out of the locking groove 605. Then, rotating the rotating rod 504 causes it to rotate via the rotating shaft B and the connecting plate B502, causing the rotating disk 602 to rotate within the rotating groove 601. This causes the limiting block 611 to slide from one inner wall of the limiting groove 610 to the other inner wall, and the rotating frame 505 to drive the clamping mechanism. Plate 506 and adapting plate 507 rotate until the limiting block 611 slides to the inner wall of the limiting groove 610 on the other side. At this time, the conversion between clamping plate 506 and adapting plate 507 is completed. Then, the movable block 607 is released. Under its own weight, the sliding block 606 will slide downward in the sliding groove 603. Since the weight of the sliding block 606 is greater than the weight of the movable block 607, the pressing block 609 will slide from the high end of the pressing groove 608 to the low end of the pressing groove 608, and the movable block 607 will slide in the opposite direction in the movable groove 604 until the pressing block 609 slides to its original position. At this time, the sliding block 606 is inserted into the locking groove 605, which fixes the position of the rotating disk 602 in the rotating groove 601 and makes the position of the rotating rod 504 more stable.

[0044] Working principle of this invention: In use, firstly, according to the required instrument valve assembly structure shape, by pressing the movable block 607, the movable block 607 slides within the movable groove 604, causing the inner wall of the extrusion groove 608 to press the extrusion block 609, causing the extrusion block 609 to slide from the lower end to the upper end of the extrusion groove 608, and causing the sliding block 606 to slide upward within the sliding groove 603 and locking groove 605 until the extrusion block 609 slides to the upper end of the extrusion groove 608. At this point, the sliding block 606 moves out of the locking groove 605. 5. Then, by rotating the knob on the rotating rod 504, the rotating rod 504 rotates through the rotating shaft B and the connecting plate B502, causing the rotating disk 602 to rotate within the rotating groove 601. This causes the limiting block 611 to slide from one inner wall of the limiting groove 610 to the other inner wall, causing the rotating frame 505 to drive the clamping plate 506 and the adapting plate 507 to rotate until the limiting block 611 slides to the other inner wall of the limiting groove 610. At this point, the connection between the clamping plate 506 and the adapting plate 507 is complete. After the conversion, the movable block 607 is released. Under its own weight, the sliding block 606 will slide downward in the sliding groove 603. Since the weight of the sliding block 606 is greater than the weight of the movable block 607, the pressing block 609 will slide from the high end of the pressing groove 608 to the low end of the pressing groove 608, causing the movable block 607 to slide in the opposite direction in the movable groove 604 until the pressing block 609 slides to its original position. At this time, the sliding block 606 is engaged with the locking groove 605, causing the rotating disk 602 to rotate. The position within the groove 601 is fixed. Next, the instrument valve assembly is placed between the two support plates 404. By rotating the handwheel on the double-acting screw 402, the double-acting screw 402 rotates with the inner wall of the moving groove 401 through the rotating shaft A, causing the moving block 403 to be threadedly connected to the double-acting screw 402. This allows the two moving blocks 403 to slide relative to each other within the moving groove 401, causing the two support plates 404 to move relative to each other until the clamping plate 506 or the adapting plate 507 contacts the surface of the instrument valve assembly, thus completing the clamping of the instrument valve assembly.Then, the drill bit on the drilling machine body 1 drills the instrument valve assembly connection hole. After drilling is completed, the servo motor 303 is started, causing the output shaft of the servo motor 303 to drive the threaded rod 305 to rotate. Due to the sliding contact between the fixed block 308 and the lower fixed part 304, the position of the connecting rod 306 is fixed, and the threaded rod 305 is threadedly connected to the connecting rod 306. The connecting rod 306 drives the cutter arm body 307 to move upward until the fixed block 308 and the lower fixed part 304 are no longer in contact. At this time, the connecting rod 306 drives the cutter arm body 307 to rotate 180 degrees, causing the fixed block 308 to slide into contact with the vertical plate of the support frame 301 until the cutter arm body 307 clamps the drill bit holder on the spindle of the drilling machine body 1. Then, the servo motor 303 is controlled to rotate. The output shaft drives the threaded rod 305 to rotate in the opposite direction. Because the fixed block 308 slides in contact with the upper fixed member 304, the connecting rod 306 drives the tool arm body 307 to move downwards until the fixed block 308 and the upper fixed member 304 are no longer in contact. At this point, the connecting rod 306 drives the tool arm body 307 to rotate 180 degrees, causing the fixed block 308 to slide in contact with the vertical plate of the support frame 301. After the tool arm body 307 moves to the cutter head position, the drill bit holder is placed inside the cutter head, and the tap holder is clamped. Subsequently, the servo motor 303 is controlled to rotate in the same direction as before, until the tool arm body 307 fixes the tap holder on the spindle of the drilling machine body 1. Then, the tap on the drilling machine body 1 can be used to tap the connection hole of the instrument valve group.
