Description

Technical Field

[0001] This application relates to the field of valve body processing technology, and in particular to a valve body fixture and its usage method. Background Technology

[0002] The valve body is a major component of a valve; by assembling certain parts onto the valve body, a valve is formed. To accommodate these parts, the valve body requires the machining of positioning holes for each component. During machining, the valve body needs to be fixed in place, which requires a valve body fixture.

[0003] Currently, valve bodies are processed by using different tooling fixtures to fix valve body blanks in different processing states. After processing is completed on the previous processing equipment, the blanks are transferred to the next equipment for subsequent processing, so that the blanks are gradually processed into valve bodies through the processing steps.

[0004] Regarding the aforementioned technologies, the inventors believe that the long process switching and debugging time required for valve body processing, the complex semi-finished product circulation and material management, result in low processing efficiency for valve bodies. Summary of the Invention

[0005] The purpose of this application is to provide a valve body fixture and its usage method to solve the problems of long process switching and debugging time, complex semi-finished product circulation and material management, and low valve body processing efficiency in valve body processing.

[0006] This application provides a valve body clamp, which adopts the following technical solution:

[0007] A valve body fixture includes a mounting base disposed on a machine tool. The mounting base has a first fixing part, on which a valve body blank is placed and fixed. A second fixing part is disposed adjacent to the first fixing part, on which a valve body blank that has been processed by the first fixing part is placed, such that the processed surface of the valve body blank corresponds to the second fixing part. A third fixing part is disposed on the side of the mounting base away from the second fixing part, and the third fixing part fixes the valve body blank that has undergone two processing steps.

[0008] By adopting the above technical solution, three fixing parts are set on the mounting base. These three fixing parts fix the valve body at different processing stages. The first fixing part fixes the initial valve body blank, the second fixing part fixes the valve body blank processed by the first fixing part, and the third fixing part fixes the valve body blank processed by the first two fixing parts, thus processing the valve body blank into a valve body. After the valve body blank is processed, the valve body blank on the third fixing part is removed, and the valve body blanks on the first and second fixing parts are sequentially transferred to the next fixing part. The new valve body blank is placed on the first fixing part and processing continues. Through the three fixing parts on the mounting base, the processing of valve body blanks at different processing stages is completed sequentially, enabling rapid turnover of valve body semi-finished products, saving material management, and improving the processing efficiency of valve body blanks.

[0009] Optionally, the first fixing part includes a fixing seat 1 disposed on the mounting base, the fixing seat 1 being used to place a valve body blank on top, and a mounting block being disposed on one side of the fixing seat 1; a clamping assembly is disposed on the mounting block, and a support block 1 is disposed on the side of the fixing seat 1 away from the clamping assembly, the support block 1 abutting against the side wall of the valve body blank; after the valve body blank is placed on the fixing seat 1, the clamping assembly drives the valve body blank towards the support block 1 to fix it between the clamping assembly and the support block 1, and a positioning member 1 abutting against the valve body blank is disposed at one end of the fixing seat 1.

[0010] By adopting the above technical solution, a fixed seat is set on the mounting base. The valve body blank placed on the fixed seat is initially positioned by a positioning component on the fixed seat. The end of the positioning component is tapered to minimize the impact of unevenness on the side wall of the valve body blank on positioning. The valve body blank is further positioned by a support block on the side wall of the fixed seat. The clamping assembly on the other side of the fixed seat clamps and fixes the valve body blank, which facilitates the processing of the valve body blank.

[0011] Optionally, the mounting block has a mounting groove corresponding to the clamping assembly. The clamping assembly includes clamping claws that abut against the side of the valve body blank away from the support block. A connecting rod is rotatably provided on the inner wall of the mounting groove, and one end of the connecting rod is connected to the clamping claws.

[0012] By adopting the above technical solution, an installation groove is opened on the installation block, and the connecting rod connected to the clamping claw is rotatably set on the inner side wall of the installation groove. By rotating the connecting rod, the clamping claw is brought close to the valve body blank, and the clamping claw pushes the valve body blank, fixing the valve body blank between the clamping claw and the first support block, and fixing the valve body blank on the first fixed seat, so as to prevent the position of the valve body blank from shifting during the processing, and thus prevent errors in the processing of the valve body blank.

[0013] Optionally, the second fixing part includes a fixing seat two disposed on the mounting base and adjacent to the fixing seat one, and the third fixing part includes a fixing seat three disposed on the mounting base and adjacent to the fixing seat two; the upper surfaces of the fixing seat two and the fixing seat three are provided with positioning elements two that are adapted to the holes on the valve body blank; the clamping assembly is also disposed on the side of the fixing seat two near the fixing seat one and the end of the fixing seat three near the fixing seat one, the other side of the fixing seat two is provided with a support block two, and the other end of the fixing seat three is provided with a support block three, so as to position and clamp the valve body blank placed on the fixing seat two and the fixing seat three.

[0014] By adopting the above technical solution, the second fixed seat is set on the mounting seat adjacent to the first fixed seat, and the third fixed seat is set on the mounting seat adjacent to the third fixed seat. Positioning element two is set on the second and third fixed seats to position the inner wall of the hole machined on the valve body blank placed on the second and third fixed seats. The valve body blank is fixed on the two fixed seats by the support blocks and clamping components set in the side wall direction of the second and third fixed seats, and the valve body blank is positioned and clamped to prevent the valve body blank from being misaligned on the second fixed seat and causing damage to the valve body blank during processing.

[0015] Optionally, a fixing groove is provided on the upper surface of the fixing seat 2 and the fixing seat 3. A positioning rod is connected to the side of the positioning member 2 near the fixing groove 1. The inner sidewall of the fixing groove 1 is adapted to the positioning member 2. The positioning member 2 is connected and disposed in the fixing groove 1. Both ends of the positioning member 2 are adapted to the holes on the valve body blank.

[0016] By adopting the above technical solution, the fixing grooves on the fixing seats 2 and 3 correspond to the positioning component 2, so that the positioning component 2 is set on the fixing seats 2 and 3. The two ends of the positioning component 2 contact the inner wall of the hole processed in the valve body blank, thus completing the initial positioning of the valve body blank and preventing the valve body blank from falling off the fixing seats 2 and 3. Then, the clamping claws of the clamping assembly fix the valve body blank on the two fixing seats, minimizing the deviation in the processing of the valve body blank due to the offset of the valve body blank during processing. The two ends of the positioning component 2 are adapted to the hole of the valve body blank, so that the inner wall of the hole processed in the valve body blank can better contact the two ends of the positioning component 2, and the valve body blank can be better placed on the fixing seats 2 and 3.

[0017] Optionally, the inner sidewall of the fixing groove on the fixing seat is provided with a fixing groove 2, and an elastic element is provided inside the fixing groove 2. The elastic element abuts against the sidewall of the positioning rod located in the fixing groove 1.

[0018] By adopting the above technical solution, a second fixing groove is opened on the inner side wall of the first fixing groove of the second fixing seat and the third fixing seat. The positioning rod is supported by the elastic element set in the second fixing groove, and the positioning rod is kept in the center position of the first fixing groove, so that the second positioning element on the positioning rod is located in the center of the fixing seat. After the second positioning element contacts the inner wall of the hole machined on the valve body blank, the clamping claw pushes the valve body blank to contact the support block, so that the second positioning element moves a small distance on the second fixing seat and the third fixing seat. When the positioning rod moves, part of the elastic element contracts, so that the valve body blank can abut against the support block in the direction of the side wall of the two fixing seats. Through the slight movement on the second fixing seat and the third fixing seat, the two ends of the second positioning element are kept in contact with the inner wall of the hole machined on the valve body blank, so as to minimize the possibility of damage to the inner wall of the hole machined on the valve body blank by the second positioning element.

[0019] Optionally, a connecting groove is provided below the mounting base along the length of the mounting base, and a connecting frame is provided in the connecting groove. The connecting frame is rotatably connected to the end of the connecting rod away from the clamping claw of the first fixed base, the second fixed base, and the three side walls of the fixed base. One end of the connecting frame is provided with a driving component connected to the mounting base. The driving component drives the connecting frame to move in the connecting groove. An isolation component is provided on the mounting block, and the isolation component is in contact with the side wall of the connecting rod.

[0020] By adopting the above technical solution, the gap between the connecting rod and the mounting block is blocked by the isolation component, preventing the cutting fluid from flowing into the gap during the machining of the valve body blank and reducing the possibility of corrosion. By rotatably connecting the connecting rod on one side of the connecting frame and the three fixed seats, the connecting frame is driven to move in the connecting groove by the driving component, which drives the connecting rod to rotate in the mounting groove of the mounting block, so that the clamping claw abuts against the valve body blank, and the valve body blanks on the three fixed seats are fixed at the same time, minimizing the possibility that any one of the valve body blanks may not be fixed.

[0021] Optionally, the support block one, the support block two, and the support block three are provided with a detachable stop block on the side near the valve body blank. The stop block abuts against the side wall of the valve body blank under the action of the clamping claw. The clamping claw is provided with a top block at the end near the valve body blank. The top block abuts against the side wall of the valve body blank when it is near the valve body blank.

[0022] By adopting the above technical solution, stops are set on the three support blocks so that the stops abut against the valve body blank. The stops can be replaced after they wear out. At the same time, when fixing blanks of different sizes, stops of different sizes can be replaced, and together with the positioning component two, the blanks can be positioned. By setting the top block on the clamping claw, the damage of the clamping claw to some machined surfaces on the valve body blank is reduced. At the same time, top blocks of different sizes can be replaced to fix blanks of different sizes.

[0023] A method of using a valve body clamp includes the following steps:

[0024] The unprocessed valve body blank is placed on the first fixed seat and clamped and fixed. The valve body blank processed at the first station is placed on the second fixed seat and positioned by the second positioning component. The valve body blank processed at both stations is placed on the third fixed seat and positioned by the second positioning component.

[0025] After the valve body blank is positioned, the valve body blank positioned on the fixed seat is clamped by the clamping assembly to prevent the valve body blank from moving on the fixed seat, and then the valve body blank is processed.

[0026] Remove the valve body blank that has been machined on the fixed seat three, move the valve body blank on the fixed seat two to the fixed seat three, move the valve body blank on the fixed seat one to the fixed seat two, place the new valve body blank on the fixed seat one, and continue machining after positioning and clamping.

[0027] Optionally, the positioning and clamping of the valve body blank includes the following steps:

[0028] After placing the valve body blank on the fixed seat, the valve body blank abuts against the positioning part at one end of the fixed seat, and at the same time, the valve body blank abuts against the stop block of the support block on one side of the fixed seat.

[0029] The positioning element 2 on the fixed seat 2 and fixed seat 3 contacts the inner wall of the hole machined in the valve body blank, so that the two ends of the positioning element 2 abut against the inner wall of the hole, and perform preliminary positioning of the valve body blank.

[0030] The drive component pushes the connecting frame to move in the connecting slot of the mounting base, causing the connecting frame to drive the connecting rod to rotate in the mounting slot of the mounting block, and causing the clamping claws on the connecting rod to push the valve body blanks on the fixed base one, fixed base two and fixed base three toward the support block.

[0031] Subsequently, the valve body blank on the first fixed seat is clamped and fixed. The elastic element in the second fixed groove on the second and third fixed seats contracts, causing the second elastic element to push the positioning rod and the second positioning element to move with the valve body blank, so that the valve body blank abuts against the stop blocks on the two support blocks, thus completing the clamping of the valve body blank on the second and third fixed seats. Then, the processing of the valve body blank begins.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. Set the fixing seat one on the mounting seat. The positioning component set on the fixing seat one is used to initially position the valve body blank placed on the fixing seat one. The support block set on the side wall of the fixing seat one is used to further position the valve body blank. The clamping component set on the other side of the fixing seat one is used to clamp and fix the valve body blank, which facilitates the processing of the valve body blank.

[0034] 2. The fixing grooves on fixing seats 2 and 3 correspond to positioning component 2, allowing positioning component 2 to be positioned on fixing seats 2 and 3. The two ends of positioning component 2 contact the inner wall of the hole machined in the valve body blank, completing the initial positioning of the valve body blank and preventing the valve body blank from detaching from fixing seats 2 and 3. Subsequently, the clamping claws of the clamping assembly fix the valve body blank on the two fixing seats, minimizing deviations in the valve body blank machining process due to offset. The two ends of positioning component 2 are adapted to the hole in the valve body blank, allowing the inner wall of the hole machined in the valve body blank to better contact the two ends of positioning component 2, and enabling the valve body blank to be better placed on fixing seats 2 and 3.

[0035] 3. Use an isolator to block the gap between the connecting rod and the mounting block to prevent cutting fluid from flowing into the gap during valve body blank machining, thus reducing the possibility of corrosion; by rotating the connecting rod on one side of the connecting frame and the three fixed seats, the connecting frame is driven to move in the connecting groove through the drive component, which in turn drives the connecting rod to rotate in the mounting groove of the mounting block, so that the clamping jaws abut against the valve body blank, and the valve body blanks on the three fixed seats are fixed at the same time, minimizing the possibility of any valve body blank not being fixed.

[0041] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0042] Example 1

[0043] A valve body clamp, as shown in the reference Figure 1 and Figure 2 This includes a metal mounting base 1 fixed to the machine tool with fixing bolts; a detachable metal fixing base 21 fixed to the mounting base 1 with bolts; a metal support block 24 fixed to the mounting base 1 with bolts on one side of the fixing base 21; a metal stop block 6 fixed to the side of the support block 24 near the fixing base 21 with bolts; the stop block 6 can be removed from the support block 24 for replacement; a metal mounting block 22 fixed to the mounting base 1 with bolts on the other side of the fixing base 21; and a metal mounting block 22 fixed to the mounting base 1 on one side of the fixing base 21. The metal positioning component 211 is fixed with bolts. The valve body blank 5 placed on the fixed seat 21 is restricted to the position of the positioning component 211 by the positioning component 211 which has a conical top. The clamping component 23 is rotated and set in the mounting groove 221 opened on the mounting block 22 by the rotating shaft. The rotation of the clamping component 23 pushes the valve body blank 5 closer to the support block 24, so that the valve body blank 5 abuts against the stop block 6 on the support block 24, thereby clamping and fixing the valve body blank 5.

[0044] Reference Figure 2 and Figure 3Fixing seat 21 is bolted to mounting seat 1 at a position adjacent to fixing seat 1. Fixing seat 21 can also be removed from mounting seat 1. Mounting block 22 is bolted to the side of support block 24 away from fixing seat 21. The connecting rod 232 of clamping assembly 23 is rotatably mounted on the inner wall of mounting groove 221 opened on mounting block 22 via a rotating shaft. Clamping claws 231 are bolted to both sides of the upper end of connecting rod 232. A metal top block is bolted to the side of clamping claw 231 near the valve body blank 5 placed on fixing seat 21. 233, the top block 233 can be removed from the clamping jaw 231 and replaced. A layer of buffer rubber is pasted on the front end of the top block to reduce the possibility of damage to the side wall of the valve body blank. On the side of the fixed seat 2 31 away from the mounting block 22, the metal support block 2 33 is fixed to the mounting seat 1 with bolts. The detachable stop block 6 is also fixed to the support block 2 33 with bolts. The rubber isolation piece 234 is fixed to the mounting block 22 with bolts so that the rubber isolation piece 234 fits against the side wall of the connecting rod 232, blocking the gap between the connecting rod 232 and the mounting block 22 and preventing the cutting fluid from entering.

[0045] Reference Figures 2 to 4 On the mounting base 1, a detachable metal fixing base 3 41 is bolted to a position adjacent to the fixing base 2 31. At the end of the fixing base 3 41 away from the fixing base 2 31, a metal support block 3 42 is bolted. A detachable stop block 6 is also fixed on the support block 3 42. At the end of the fixing base 3 41 near the fixing base 2 31, a mounting block 22 is bolted. The clamping assembly 23 is rotatably set in the mounting groove 221 of the mounting block 22. A fixing groove 311 is opened on the upper surface of the fixing base 2 31 and the fixing base 3 41. The positioning rod 321 integrally formed on the metal positioning part 2 32 is installed in the fixing groove 311. The positioning part 2 32 is located above the fixing base. The two ends of the positioning part 2 32 are adapted to the inner wall of the hole machined in the valve body blank 5. A second fixing groove 312 is opened on the inner side wall of the first fixing groove 311. An elastic element 322, which is abuts against the side wall of the positioning rod 321, is set in the second fixing groove 312. The elastic element 322 is a spring. When the clamping claw 231 pushes the valve body blank 5 close to the support block, the second fixing element 32 moves a small distance on the second fixing seat 31 and the third fixing seat 41. Part of the spring contracts under the action of the positioning rod 321, which moves with the second fixing element 32, so that the valve body blank 5 can abut against the stop block 6 on the support block in the direction of the side wall of the two fixing seats. The second fixing element 32 maintains contact with the inner side wall of the hole machined in the valve body blank 5 by slightly moving on the second fixing seat 31 and the third fixing seat 41, so as to minimize the possibility of the second fixing element 32 damaging the inner wall of the hole machined in the valve body blank 5.

[0046] Reference Figures 2 to 4A connecting groove 11 is provided below the mounting base 1 along the length of the mounting base 1. A connecting frame 12 is provided in the connecting groove 11. The connecting frame 12 can move in the connecting groove 11. The bottom ends of the connecting rods 232 on the side walls of the three fixed seats are rotatably connected to the connecting frame 12 through a rotating shaft. A driving component 13 is fixed below the mounting base 1 with bolts. The driving component 13 is a driving cylinder. The driving rod of the driving cylinder is fixed to one end of the connecting frame 12 with bolts. The driving component 13 drives the connecting frame 12 to move, which drives the connecting rods 232 to rotate in the mounting groove 221 of the mounting block 22. This causes the clamping claws 231 on the side walls of the three fixed seats to approach the fixed seats, and simultaneously clamps the valve body blanks 5 with different processing degrees placed on the three fixed seats. By changing the stop block 6 on the support block, the top block 233 on the clamping claws 231 and the three fixed seats, valve bodies of different specifications can be positioned and processed, reducing the process switching and debugging time.

[0047] Example 2

[0048] S100, place the unprocessed valve body blank 5 on the fixed seat 1 21, clamp and fix the valve body blank 5, place the valve body blank 5 processed by station 1 on the fixed seat 2 31, and position it by the positioning part 2 32, place the valve body blank 5 processed by two stations on the fixed seat 3 41, and position it by the positioning part 2 32.

[0049] S110, after placing the valve body blank 5 on the fixed seat 21, the valve body blank 5 abuts against the positioning member 211 provided at the end of the fixed seat 21, and at the same time, the valve body blank 5 abuts against the stop block 6 of the support block 24 on one side of the fixed seat 21.

[0050] S120, the positioning element 2 32 provided on the fixing seat 2 31 and fixing seat 3 41 contacts the inner wall of the hole machined in the valve body blank 5, so that the two ends of the positioning element 2 32 abut against the inner wall of the hole, and perform preliminary positioning of the valve body blank 5.

[0051] S200, after the valve body blank 5 is positioned, the valve body blank 5 positioned on the fixed seat is clamped by the clamping assembly 23 to prevent the valve body blank 5 from moving on the fixed seat, and then the valve body blank 5 is processed.

[0052] S210, the drive component 13 pushes the connecting frame 12 to move in the connecting groove 11 of the mounting base 1, so that the connecting frame 12 drives the connecting rod 232 to rotate in the mounting groove 221 of the mounting block 22, so that the clamping claws 231 on the connecting rod 232 push the valve body blank 5 on the fixed base 1 21, fixed base 2 31 and fixed base 3 41 toward the support block;

[0053] S220, then the valve body blank 5 on the fixed seat 1 21 is clamped and fixed, the elastic element 322 in the fixed groove 2 312 on the fixed seat 2 31 and the fixed seat 3 41 contracts, so that the elastic element 322 pushes the positioning rod 321 and the positioning element 2 32 to move with the valve body blank 5, so that the valve body blank 5 abuts against the stop block 6 on the two support blocks, so that the valve body blank 5 on the fixed seat 2 31 and the fixed seat 3 41 is clamped, and then the valve body blank 5 is processed.

[0054] S300, remove the valve body blank 5 that has been machined on the fixed seat 3 41, move the valve body blank 5 on the fixed seat 2 31 to the fixed seat 3 41, move the valve body blank 5 on the fixed seat 1 21 to the fixed seat 2 31, place the new valve body blank 5 on the fixed seat 1 21, and continue machining after positioning and clamping.

[0055] The implementation principle of this application embodiment is as follows:

[0056] Open the clamping jaws 231 above the mounting base 1, and place the valve body blank 5 on the fixing base 1 21, so that the valve body blank 5 abuts against the positioning part 211 on the fixing base 1 21 and the stop block 6 on the support block on the side wall of the fixing base 1 21, thus completing the positioning of the valve body blank 5; place the valve body blank 5 that has been fixed and machined by the fixing base 1 21 on the fixing base 2 31, and place the valve body blank 5 that has been fixed and machined by the fixing base 2 31 on the fixing base 3 41, so that the inner side wall of the hole machined in the valve body blank 5 is flush with the fixing base 2 31 and the fixing base 31. Positioning element 232 on the third 41 contacts, causing positioning element 232 to abut against the inner wall of the hole machined in the valve body blank 5; then, the drive element 13 is activated to drive the connecting frame 12 to move, causing the connecting frame 12 to drive the connecting rod 232 to rotate in the mounting groove 221 of the mounting block 22, so that the clamping claws 231 on the connecting rod 232 on the side wall of the first fixed seat 21 clamp the valve body blank 5 on the first fixed seat 21, and the clamping claws 231 on the connecting rod 232 on the side wall of the second fixed seat 31 and the third fixed seat 41 push the valve body blank 5 against the support. Support block 233 and support block 32 abut against each other, causing positioning element 232 on fixed seat 231 and fixed seat 341 to move toward the support block. The elastic element 322 in the fixed groove 2312 deforms under the action of the positioning rod 321 connected to positioning element 232, thus positioning and clamping the valve body blank 5 on fixed seat 231 and fixed seat 341. The fixed valve body blank 5 is then processed. After processing, the clamping jaws 231 are moved away from the valve body blank 5, and the positioning element 232 on fixed seat 231 and fixed seat 341... When the elastic element 322 resets, it moves the valve body away from the support block, removes the valve body blank 5 that has been processed on the fixed seat 3 41, moves the valve body blank 5 on the fixed seat 2 31 to the fixed seat 3 41, moves the valve body blank 5 on the fixed seat 1 21 to the fixed seat 2 31, places a new valve body blank 5 on the fixed seat 1 21, and continues processing; the valve body at different processing stages is processed through the three fixing parts on the mounting seat 1, realizing blank in and finished product out, saving process switching and debugging time, and improving the processing efficiency of the valve body.
