Description

Technical Field

[0001] This invention belongs to the field of piston equipment technology, specifically relating to a method for manufacturing a high-strength floating piston. Background Technology

[0002] Most shock absorbers used in vehicles are hydraulic shock absorbers. When a vehicle is traveling on bumps, the piston rod inside the hydraulic shock absorber continuously extends and retracts within the cylinder, and the damping oil inside the cylinder continuously flows up and down through the valve plates in the valve body to buffer the impact force and reduce the degree of bumps.

[0003] The floating piston is an important component in the shock absorber. Because the upper chamber of the shock absorber cylinder contains shock absorber oil and the lower chamber contains high-pressure nitrogen, it requires good sealing and strength to separate the two media. At the same time, due to the volume change of the upper chamber caused by the up-and-down movement of the piston rod, the floating piston needs to be able to slide smoothly up and down along the inner wall of the working cylinder. Furthermore, when the floating piston slides up and down, it will generate frictional heat, so the floating piston needs to have good resistance to thermal deformation.

[0004] The piston rod is connected to the piston cavity, and the piston rod drives the piston to move up and down in the cylinder. The connection between the piston rod and the piston is crucial. Therefore, it is urgent to design a high-strength piston. Summary of the Invention

[0005] The purpose of this invention is to solve the aforementioned technical problems in the prior art and provide a manufacturing method for a high-strength floating piston. First, the piston body and connecting part are formed by a molding machine. Then, a limiting and reinforcing assembly is installed on the connecting part. Next, the piston body is clamped and fixed using a fixing assembly in an assembly table. The connecting part is placed under a U-shaped mounting bracket, and the threaded connecting post is screwed into the large threaded connecting hole of the connecting part, fixing the connecting part to the bottom of the threaded connecting rod. Simultaneously, the clamping part is controlled to clamp the outer wall of the connecting part, increasing the stability of the connecting part clamping. The fixing assembly is then driven towards the U-shaped... The mounting bracket moves to one side, positioning the piston body below the connecting part. The push cylinder in the U-shaped mounting bracket controls the clamping assembly to move the connecting part into the cavity of the piston body. The limiting and fixing assembly is then pressed against the inner wall of the cavity, fixing the connecting part in the cavity. The fixing assembly is then driven to reset, and the pin is released. The rotating component is controlled to rotate the piston body. After the piston body reverses, the pin is reset, and the screw is screwed into the piston body and tightened into the connecting part, thus fixing the connecting part to the piston body. After the floating piston is assembled, the push component is released and removed, completing the manufacturing process.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A method for manufacturing a high-strength floating piston, the floating piston comprising a piston body and a connecting part, the piston body having a cavity, the connecting part being fixedly connected to the cavity, the connecting part having a threaded connection hole, a limiting and reinforcing component being provided between the connecting part and the cavity, and fixing posts circumferentially distributed at one end of the connecting part abutting against the inner wall of the cavity, the fixing posts having connecting screw holes, the piston body having corresponding stepped holes, and connecting screws being screwed into the stepped holes and tightened into the connecting screw holes. The floating piston manufacturing method includes the following steps:

[0008] a. Preparations before manufacturing

[0009] First, the workpiece is forged and pressed using a forming machine to form the piston body and connecting part. The surfaces of the piston body and connecting part are then cleaned. Finally, the limiting and reinforcing components are clamped on the outside of the connecting part.

[0010] b. Assembly

[0011] 1) Fixing the piston body

[0012] First, place the piston body in the fixing assembly on the assembly table. The fixing assembly is slidably connected to the assembly table. The piston body is fixed in the fixing assembly by the pushers on both sides of the fixing assembly pressing against the outside of the piston body.

[0013] 2) Fixing of the connecting parts

[0014] Place the connecting part with the limit reinforcement component under the U-shaped mounting bracket. Control the threaded connecting post in the clamping component to screw into the connecting part, so that the connecting part is fixedly connected to the bottom of the threaded connecting post. Then control the clamping part in the clamping component to clamp the outer wall of the connecting part, thereby fixing the connecting part under the U-shaped mounting bracket.

[0015] c. Fixing of the piston body and the connecting part

[0016] 1) Installation of the connecting parts

[0017] The fixed component on the drive assembly table moves the piston body toward the U-shaped mounting bracket, so that the piston body is below the connecting part. Then the U-shaped mounting bracket controls the connecting part to descend, so that the connecting part is placed in the cavity. Then the end of the control limiting and reinforcing component is pressed against the inner wall of the cavity, so that the connecting part is fixedly connected in the cavity.

[0018] 2) Flip

[0019] The fixed assembly on the assembly table is reset again. By loosening the pin in the fixed assembly, the rotating part in the fixed assembly is driven to rotate the piston body. After the piston body flips, the pin is reinserted, and the connecting screw is passed through the piston body and tightened in the connecting part, thereby fixing the connecting part and the piston body.

[0020] d. Complete manufacturing

[0021] The pushers on both sides of the fixed assembly are released, thereby removing the assembled floating piston from the fixed assembly and completing the manufacturing process.

[0022] Furthermore, the limiting and reinforcing assembly includes a clamping member and a pressing member. One end of the pressing member is fixedly connected to the clamping member, and the other end of the pressing member abuts against the inner wall of the cavity. The clamping member is clamped to the outside of the connecting part. The clamping member is used to clamp onto the connecting part, thereby improving the structural strength of the connecting part. One end of the pressing member is connected to the clamping member, and the other end of the pressing member abuts against the inner wall of the cavity, thereby increasing the contact area between the connecting part and the cavity, thus improving the stability of the connection between the connecting part and the cavity.

[0023] Furthermore, the clamping component includes semi-circular clips and connecting screws. Two semi-circular clips are mirror-mounted on both sides of the connecting part, clamping the two sides of the connecting part. Each end of the semi-circular clip has a fixing block. The connecting screw passes through the corresponding two fixing blocks, and both ends of the connecting screw are screwed with fastening nuts, which are tightened onto the fixing blocks. The clamping component is used to clamp onto the connecting part, thereby improving the structural strength of the connecting part. One end of the pressing component is connected to the clamping component, and the other end of the pressing component presses against the inner wall of the cavity, thereby increasing the contact area between the connecting part and the cavity, thus improving the stability of the connection between the connecting part and the cavity. The two semi-circular clips are clamped on both sides of the connecting part, the connecting screw passes through the corresponding two fixing blocks, and then the fastening nuts are screwed into both ends of the connecting screw and tightened onto the fixing blocks for fixation, thus fixing the clamping component to the connecting part.

[0024] Furthermore, the clamping component includes connecting rod one, connecting rod two, and a clamping block. One end of connecting rod one is fixedly connected to the clamping component, and one end of connecting rod two is telescopically connected to the other end of connecting rod one. Clamping screws are distributed circumferentially on the other end of connecting rod one, and these screws clamp onto one end of connecting rod two. The other end of connecting rod two is fixedly connected to the clamping block. Connecting rod two controls the clamping block to press against the inner wall of the cavity. A connecting seat is provided inside the cavity corresponding to connecting rod one, and the connecting seat has a slot. Connecting rod one is clamped in the slot. Connecting rod two is telescopically connected to connecting rod one. Connecting rod one is fixed to the clamping component, and connecting rod two drives the clamping block to press against the inner wall of the cavity. The clamping screws on connecting rod one clamp connecting rod two, thereby fixing connecting rod two to connecting rod one.

[0025] Furthermore, the assembly table includes a tabletop, a slide rail, a fixing component, and a U-shaped mounting bracket. The slide rail is fixedly connected to the tabletop, the fixing component is located at one end of the tabletop and slidably connected to the slide rail, and the U-shaped mounting bracket is located at the other end of the tabletop. The fixing component is positioned at one end of the tabletop, and the U-shaped mounting bracket is positioned at the other end. By driving the fixing component to slide along the slide rail, the fixing component can slide under the U-shaped mounting bracket.

[0026] Furthermore, the fixing assembly includes a fixing frame, a pushing member, a rotating member, and a pin member. The rotating member is rotatably connected to both sides of the fixing frame. The pushing member is disposed on the rotating member and presses against both sides of the piston body. The pin member is disposed on one side of the fixing frame and is used to limit the rotating member. The pin member is used to limit the rotating member, and the pushing member presses against both sides of the piston body, thus fixing the piston body in the fixing frame.

[0027] Furthermore, the fixing frame includes a first fixing plate, a second fixing plate, and a connecting rod. The first fixing plate and the second fixing plate are fixed together by the connecting rod. The rotating component includes a first turntable and a second turntable. The first fixing plate has a through hole, and the first turntable is rotatably connected in the through hole. Limiting blocks are distributed along the circumference of the through hole on both sides of the first fixing plate, and the limiting blocks abut against the first turntable. Both sides of the first turntable have pin holes, and the pin holes are matched with pin components. The pin component includes a bracket, a pin, and a spring. The bracket is fixedly connected to the first fixing plate. On both sides, the pin passes through the bracket and the first fixing plate and is inserted into the pin hole. The spring is sleeved on the outside of the pin and is located between the bracket and the first fixing plate. The outside of the pin is provided with a positioning block, and the bracket is provided with a positioning hole. The second fixing plate is provided with a through hole. The second turntable is rotatably connected in the through hole. The outer circumference of the second turntable is provided with a limiting part, and the inner wall of the second through hole is provided with a limiting groove. The limiting part is located in the limiting groove. The two sides of the second fixing plate are distributed with limiting blocks 2 along the circumference of the second through hole. The limiting blocks 2 abut against the second turntable. The connecting rod securely connects fixed plate one and fixed plate two, creating a cavity between them for clamping the piston body. Turntable one is rotatably connected to through hole one in fixed plate one. The limiting block one keeps turntable one within the through hole one. Pulling the pin causes the spring to contract, controlling the positioning block to pass through the positioning hole. Then, the pin rotates, causing the positioning block to press against the bracket, thus removing the pin from the pin hole. This allows turntable one to rotate within the through hole one. After rotation, the pin is rotated back, the spring extends, and... After the positioning block passes through the positioning hole, it is located between the bracket and the first fixed plate, so that the pin is reinserted into the pin hole, and the first turntable is fixed in the first through hole. The second turntable is rotatably connected to the second through hole of the second fixed plate. The second limiting block limits the turntable in the second through hole. The setting of the limiting part and the limiting groove plays a limiting role for the second turntable, so that the second turntable rotates in the second through hole. At the same time, it increases the smoothness of the rotation of the second turntable in the second through hole. When the pusher is clamped on the piston body, controlling the rotation of the first turntable can drive the second turntable to rotate. After the first turntable is fixed in the first through hole, the second turntable is synchronously limited in the second through hole.

[0028] Furthermore, the pushing component includes an adjusting screw, an adjusting plate, and a clamping frame. The adjusting screw on one side passes through turntable one, and the adjusting screw on the other side passes through turntable two. The adjusting plate is fixedly connected to the end of the adjusting screw. Both adjusting plates are located between fixed plate one and fixed plate two. Adjusting nuts are provided at both ends of the adjusting screw, and these nuts are tightened onto turntable one and turntable two, respectively. One end of the clamping frame is fixedly connected to the adjusting plate, and the other end is clamped to the outside of the piston body. Loosening the adjusting nut through the through hole drives the adjusting screw, causing the adjusting plate and clamping frame to move towards one side of the piston body, so that the clamping frame clamps both sides of the piston body. Tightening the adjusting nut then clamps the piston body between the two clamping frames. With the adjusting screws respectively positioned on turntable one and turntable two, the rotating component can drive the piston body to rotate.

[0029] Furthermore, a push cylinder is provided at the top of the U-shaped mounting bracket. The output end of the push cylinder passes through the U-shaped mounting bracket and is fixedly connected to the top of the clamping assembly. The clamping assembly is used to clamp the connecting part, and the push cylinder controls the clamping assembly to drive the connecting part to rise and fall. The push cylinder controls the clamping assembly to rise and fall by pushing it.

[0030] Furthermore, the clamping part includes a fixed seat, a clamping plate, a threaded connecting column, a clamping part, and a threaded adjusting rod. The top of the fixed seat is fixedly connected to the bottom surface of the conveying end of the push cylinder. The bottom of the fixed seat and the top of the clamping plate are fixedly connected by a column. The threaded connecting column is threadedly connected to the center of the clamping plate and passes through the clamping plate. The threaded connecting column is matched with the threaded connecting hole of the connecting part. An adjusting groove passes through the circumference of the top surface of the clamping plate. A guide rail is provided at the bottom of the clamping plate for the adjusting groove. The bottom of the threaded adjusting rod passes through the adjusting groove and is threadedly connected to the top surface of the clamping part. A guide block is provided at the top of the clamping part and is slidably connected in the guide rail. The bottom of the clamping part abuts against the outer wall of the connecting part. First, screw the threaded connecting post downwards so that it is screwed into the threaded hole of the connecting part, thus fixing the connecting part to the bottom of the threaded connecting post. Then, loosen the threaded adjusting rod, which can drive the threaded adjusting post to move the clamping part along the direction of the adjusting groove, so that the bottom of the clamping part is clamped on the outer wall of the connecting part. Then, tighten the threaded adjusting rod on the top surface of the clamping plate to fix the clamping part, making the connecting part unable to rotate, thus increasing the stability of the clamping of the connecting part. The guide rail plays a guiding role in the sliding of the clamping part.

[0031] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0032] This invention first uses a molding machine to form the piston body and connecting part. Then, a limiting and reinforcing component is installed on the connecting part. Next, the piston body is clamped and fixed by a fixing component in the assembly table. The connecting part is placed under the U-shaped mounting bracket. The threaded connecting post is screwed into the large threaded connecting hole of the connecting part, fixing the connecting part to the bottom of the threaded connecting rod. At the same time, the clamping part is controlled to clamp the outer wall of the connecting part, increasing the stability of the connecting part clamping. The fixing component is driven to move to one side of the U-shaped mounting bracket, so that the piston body is below the connecting part. The push cylinder in the U-shaped mounting bracket controls the clamping component to move the connecting part into the cavity of the piston body. Then, the limiting and fixing component is pressed against the inner wall of the cavity, fixing the connecting part in the cavity. The fixing component is then driven to reset, and the pin is released. The rotating component is controlled to drive the piston body to rotate. After the piston body reverses, the pin is reset, and the screw is screwed into the piston body and tightened into the connecting part, thus fixing the connecting part to the piston body. After the floating piston is assembled, the push component is released and removed, completing the manufacturing process.

[0033] In this invention, the clamping component includes a first connecting rod, a second connecting rod, and a clamping block. One end of the first connecting rod is fixedly connected to a clamping component. One end of the second connecting rod is telescopically connected to the other end of the first connecting rod. Clamping screws are distributed circumferentially on the other end of the first connecting rod, clamping them against one end of the second connecting rod. The other end of the second connecting rod is fixedly connected to the clamping block. The second connecting rod controls the clamping block to press against the inner wall of the cavity. A connecting seat is provided inside the cavity corresponding to the first connecting rod, and the connecting seat has a slot. The first connecting rod is clamped in the slot. The second connecting rod is telescopically connected to the first connecting rod. The first connecting rod is fixed to the clamping component. The second connecting rod drives the clamping block to press against the inner wall of the cavity. The clamping screws on the first connecting rod clamp the second connecting rod, thereby fixing the second connecting rod to the first connecting rod.

[0034] In this invention, the fixing frame includes a first fixing plate, a second fixing plate, and a connecting rod. The first fixing plate and the second fixing plate are fixed together by the connecting rod. The rotating component includes a first turntable and a second turntable. The first fixing plate has a through hole, and the first turntable is rotatably connected in the through hole. Limiting blocks are distributed along the circumference of the through hole on both sides of the first fixing plate, and the limiting blocks abut against the first turntable. Both sides of the first turntable have pin holes, and the pin holes are matched with pin components. The pin component includes a bracket, a pin, and a spring. The bracket is fixedly connected to the first fixing plate. On both sides, the pin passes through the bracket and the first fixing plate and is inserted into the pin hole.

The outside of the pin is provided with a positioning block, and the bracket is provided with a positioning hole. The second fixing plate is provided with a through hole. The second turntable is rotatably connected in the through hole. The outer circumference of the second turntable is provided with a limiting part, and the inner wall of the second through hole is provided with a limiting groove. The limiting part is located in the limiting groove. The two sides of the second fixing plate are distributed with limiting blocks 2 along the circumference of the second through hole. The limiting blocks 2 abut against the second turntable. The connecting rod securely connects fixed plate one and fixed plate two, creating a cavity between them for clamping the piston body. Turntable one is rotatably connected to through hole one in fixed plate one. The limiting block one keeps turntable one within the through hole one. Pulling the pin causes the spring to contract, controlling the positioning block to pass through the positioning hole. Then, the pin rotates, causing the positioning block to press against the bracket, thus removing the pin from the pin hole. This allows turntable one to rotate within the through hole one. After rotation, the pin is rotated back, the spring extends, and... After the positioning block passes through the positioning hole, it is located between the bracket and the first fixed plate, so that the pin is reinserted into the pin hole, and the first turntable is fixed in the first through hole. The second turntable is rotatably connected to the second through hole of the second fixed plate. The second limiting block limits the turntable in the second through hole. The setting of the limiting part and the limiting groove plays a limiting role for the second turntable, so that the second turntable rotates in the second through hole. At the same time, it increases the smoothness of the rotation of the second turntable in the second through hole. When the pusher is clamped on the piston body, controlling the rotation of the first turntable can drive the second turntable to rotate. After the first turntable is fixed in the first through hole, the second turntable is simultaneously fixed in the second through hole.

[0035] In this invention, the clamping part includes a fixed base, a clamping plate, a threaded connecting column, a clamping part, and a threaded adjusting rod.

A guide rail is provided at the bottom of the clamping plate for the adjusting groove. The bottom of the threaded adjusting rod passes through the adjusting groove and is threadedly connected to the top surface of the clamping part. A guide block is provided at the top of the clamping part and is slidably connected in the guide rail. The bottom of the clamping part abuts against the outer wall of the connecting part. First, screw the threaded connecting post downwards so that it is screwed into the threaded hole of the connecting part, thus fixing the connecting part to the bottom of the threaded connecting post. Then, loosen the threaded adjusting rod, which can drive the threaded adjusting post to move the clamping part along the direction of the adjusting groove, so that the bottom of the clamping part is clamped on the outer wall of the connecting part. Then, tighten the threaded adjusting rod on the top surface of the clamping plate to fix the clamping part, making the connecting part unable to rotate, thus increasing the stability of the clamping of the connecting part. The guide rail plays a guiding role in the sliding of the clamping part. Attached Figure Description

One end of the pressing member 12 is connected to the clamping member 11, and the other end of the pressing member 12 abuts against the inner wall of the cavity 4, thereby increasing the contact area between the connecting part 3 and the cavity 4, thereby improving the stability of the connection between the connecting part 3 and the cavity 4.

[0054] The clamping member 11 includes a semi-circular clamp 13 and a connecting screw 14. The two semi-circular clamps 13 are mirror images of each other on both sides of the connecting part 3, and are clamped to both sides of the connecting part 3.

The clamping member 11 is used to clamp onto the connecting part 3, thereby improving the structural strength of the connecting part 3. One end of the clamping member 12 is connected to the clamping member 11, and the other end of the clamping member 12 is pressed against the inner wall of the cavity 4, thereby increasing the contact area between the connecting part 3 and the cavity 4, and thus improving the stability of the connection between the connecting part 3 and the cavity 4. Two semi-circular clips 13 are clamped on both sides of the connecting part 3. The connecting screw 14 passes through the corresponding two fixing blocks 15. Then, the fastening nut 16 is screwed into both ends of the connecting screw 14 and tightened on the fixing block 15 for fixation, thereby making the clamping part 11 fixedly connected to the connecting part 3.

[0055] The clamping component 12 includes a first connecting rod 17, a second connecting rod 18, and a clamping block 19. One end of the first connecting rod 17 is fixedly connected to the clamping component 11. One end of the second connecting rod 18 is telescopically connected to the other end of the first connecting rod 17. The other end of the first connecting rod 17 has clamping screws 20 distributed around its circumference. The clamping screws 20 are clamped to one end of the second connecting rod 18. The other end of the second connecting rod 18 is fixedly connected to the clamping block 19. The second connecting rod 18 controls the clamping block 19 to press against the inner wall of the cavity 4. A connecting seat 21 is provided in the cavity 4 corresponding to the first connecting rod 17. The connecting seat 21 has a slot, and the first connecting rod 17 is clamped in the slot. Link 2 18 is telescopically connected to link 1 17. Link 1 17 is fixed on clamping member 11. Link 2 18 drives the clamping block 19 to press against the inner wall of cavity 4. Link 2 18 is pressed against the clamping screw 20 on link 1 17, thereby fixing link 2 18 and link 1 17.

[0056] like Figure 1 and Figure 12 The figure shows a method for manufacturing the high-strength floating piston of the present invention, which includes the following steps:

[0057] a. Preparations before manufacturing

[0058] First, the workpiece is forged using a forming machine to form the piston body 2 and the connecting part 3. The surfaces of the piston body 2 and the connecting part 3 are cleaned. Then, the limiting and reinforcing component 6 is clamped on the outside of the connecting part 3.

[0059] b. Assembly

[0060] 1) Fixing the piston body

[0061] First, place the piston body 2 in the fixing component 26 of the assembly table 23. The fixing component 26 is slidably connected to the assembly table 23. The piston body 2 is fixed in the fixing component 26 by the pushers 29 on both sides of the fixing component 26 pressing against the outside of the piston body 2.

[0062] 2) Fixing of the connecting parts

[0063] Place the connecting part 3 with the limit reinforcement component 6 under the U-shaped mounting bracket 27, and screw the threaded connecting post in the clamping component 54 into the connecting part 3 so that the connecting part 3 is fixedly connected to the bottom of the threaded connecting post. Then, control the clamping part in the clamping component 54 to clamp the outer wall of the connecting part 3, thereby fixing the connecting part 3 under the U-shaped mounting bracket 27.

[0064] c. Fixing of the piston body and the connecting part

[0065] 1) Installation of connecting part 3

[0066] The fixing component 26 on the drive assembly table 23 drives the piston body 2 to move towards the side of the U-shaped mounting bracket 27, so that the piston body 2 is below the connecting part 3. Then the U-shaped mounting bracket 27 controls the connecting part 3 to descend, so that the connecting part 3 is placed in the cavity 4. Then the end of the control limiting and reinforcing component 6 is pressed against the inner wall of the cavity 4, so that the connecting part 3 is fixedly connected in the cavity 4.

[0067] 2) Flip

[0068] The fixed assembly 26 on the assembly table 23 is reset again.

The fixing component 26 is located at one end of the tabletop 24 and is slidably connected to the slide rail 25. The U-shaped mounting bracket 27 is located at the other end of the tabletop 24. The fixing component 26 is located at one end of the tabletop 24, and the U-shaped mounting bracket 27 is located at the other end of the tabletop 24. By driving the fixing component 26 to slide on the slide rail 25, the fixing component 26 can slide under the U-shaped mounting bracket 27.

[0072] The fixing assembly 26 includes a fixing frame 28, a pushing member 29, a rotating member 30, and a pin member 31. The rotating member 30 is rotatably connected to both sides of the fixing frame 28. The pushing member 29 is disposed on the rotating member 30 and is pressed against both sides of the piston body 2. The pin member 31 is disposed on one side of the fixing frame 28 and is used to limit the rotating member 30. The pin member 31 is provided to limit the rotating member 30, and the pushing member 29 is pressed against both sides of the piston body 2, so that the piston body 2 is fixed in the fixing frame 28.

[0073] The fixing frame 28 includes a first fixing plate 32, a second fixing plate 33, and a connecting rod 34. The first fixing plate 32 and the second fixing plate 33 are fixed together by the connecting rod 34. The rotating component 30 includes a first turntable 35 and a second turntable 36. The first fixing plate 32 is provided with a first through hole 37. The first turntable 35 is rotatably connected in the first through hole 37. Limiting blocks 38 are distributed on both sides of the first fixing plate 32 along the circumference of the first through hole 37. The limiting blocks 38 abut against the first turntable 35. Both sides of the first turntable 35 are provided with pin holes 39. The pin holes 39 are matched with pin components 31. The pin component 31 includes a bracket 40, a pin 41, and a spring 42. The bracket 40 is fixedly connected to the two sides of the first fixing plate 32. On one side, the pin 41 passes through the bracket 40 and the fixing plate 32 and is inserted into the pin hole 39. The spring 42 is sleeved on the outside of the pin 41 and is located between the bracket 40 and the fixing plate 32. The outside of the pin 41 is provided with a positioning block 43, and the bracket 40 is provided with a positioning hole 44. The fixing plate 33 is provided with a through hole 45.

The limiting part 46 is located in the limiting groove 47. The two sides of the fixing plate 33 are distributed with limiting blocks 48 along the circumference of the through hole 45. The limiting blocks 48 abut against the turntable 36. The connecting rod 34 securely connects the first fixing plate 32 and the second fixing plate 33, while also creating a cavity between the first fixing plate 32 and the second fixing plate 33 via the connecting rod 34, for clamping the piston body 2. The turntable 35 is rotatably connected in the through hole 37 of the first fixing plate 32. The limiting block 38 limits the turntable 35 in the through hole 37. By pulling the pin 41, the spring 42 contracts, controlling the positioning block 43 to pass through the positioning hole 44. Then, the pin 41 is rotated, causing the positioning block 43 to abut against the bracket 40, thereby removing the pin 41 from the pin hole 39, allowing the turntable 35 to rotate in the through hole 37. After the rotation is completed, the pin 41 is rotated back, the spring 42 extends, and the piston body 2 is clamped. After the positioning block 43 passes through the positioning hole 44, it is located between the bracket 40 and the fixing plate 32, so that the pin 41 is reinserted into the pin hole 39, and the turntable 35 is fixed in the through hole 37. The turntable 36 is rotatably connected in the through hole 45 of the fixing plate 33. The limiting block 48 limits the turntable in the through hole 45. The setting of the limiting part 46 and the limiting groove 47 plays a limiting role for the turntable 36, so that the turntable 36 rotates in the through hole 45, and at the same time increases the smoothness of the turntable 36 rotating in the through hole 45. When the pusher 29 is clamped on the piston body 2, the rotation of the turntable 1 can be controlled to drive the turntable 36 to rotate. After the turntable 35 is fixed in the through hole 37, the turntable 36 is simultaneously limited in the through hole 45.

[0074] The pusher 29 includes an adjusting screw 49, an adjusting plate 50, and a clamping frame 51.

One end of the clamping frame 51 is fixedly connected to the adjusting plate 50, and the other end of the clamping frame 51 is clamped to the outside of the piston body 2. Loosen the adjusting nut 52 through the through hole, drive the adjusting screw 49 to move the adjusting plate 50 and the clamping frame 51 to one side of the piston body 2, so that the clamping frame 51 clamps the two sides of the piston body 2. Then tighten the adjusting nut 52, so that the piston body 2 is clamped in the two clamping frames 51. The adjusting screw 49 is respectively set on the first turntable 35 and the second turntable 36, so that the rotating part 30 can drive the piston body 2 to rotate.

[0075] The top of the U-shaped mounting bracket 27 is equipped with a push cylinder 53. The output end of the push cylinder 53 passes through the U-shaped mounting bracket 27 and is fixedly connected to the top of the clamping assembly 54. The clamping assembly 54 is used to clamp the connecting part 3. The push cylinder 53 controls the clamping assembly 54 to drive the connecting part 3 to rise and fall. The push cylinder 53 controls the clamping assembly 54 to rise and fall by pushing it.

[0076] The clamping part includes a fixed base 55, a clamping plate 56, a threaded connecting column 57, a clamping part 58, and a threaded adjusting rod 59. The top of the fixed base 55 is fixedly connected to the bottom surface of the conveying end of the push cylinder 53. The bottom of the fixed base 55 is fixedly connected to the top of the clamping plate 56 through a column 60. The threaded connecting column 57 is threadedly connected to the center of the clamping plate 56 and passes through the clamping plate 56. The threaded connecting column 57 is matched with the threaded connecting hole 5 of the connecting part 3. An adjusting groove 61 passes through the circumference of the top surface of the clamping plate 56. The bottom of the clamping plate 56 is provided with a guide rail 61 for the adjusting groove 61. The bottom of the threaded adjusting rod 59 passes through the adjusting groove 61 and is threadedly connected to the top surface of the clamping part 58. A guide block 22 is provided on the top of the clamping part 58. The guide block 22 is slidably connected in the guide rail 61. The bottom of the clamping part 58 abuts against the outer wall of the connecting part 3. First, screw the threaded connecting post 57 downwards so that it is screwed into the threaded hole of the connecting part 3, thereby fixing the connecting part 3 to the bottom of the threaded connecting post 57. Then, loosen the threaded adjusting rod 59, which can drive the threaded adjusting post to slide the clamping part 58 along the direction of the adjusting groove 61, so that the bottom of the clamping part 58 is clamped on the outer wall of the connecting part 3. Then, tighten the threaded adjusting rod 59 on the top surface of the clamping plate 56, thereby fixing the clamping part 58 and preventing the connecting part 3 from rotating, thus increasing the stability of the clamping of the connecting part 3. The guide rail 61 plays a guiding role in the sliding of the clamping part 58.

[0077] This invention provides a connecting part within the piston cavity, with a threaded connecting hole for connecting the piston rod. A limiting and reinforcing component is also provided within the cavity, with one end of the component pressing against the inner wall of the cavity and the other end clamping against the outer wall of the connecting part. This increases the contact area between the connecting part and the cavity, thereby improving the stability of the connection between the connecting part and the cavity, and also enhancing the structural strength of the connecting part.

Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
