Description

Technical Field

[0001] The present invention relates to the technical field of sealing sleeve mounting mechanisms, and in particular to a mounting mechanism for a sealing sleeve on a shift base. Background Art

[0002] The sealing sleeve installation mechanism refers to a mechanism that uses mechanical stamping to install the sealing sleeve, and is designed to install the sealing sleeve in the fixed hole of the shift base. The sealing sleeve installation mechanism is an important mechanism in the installation process of the mechanical industry. The sealing sleeve installation mechanism helps workers install the sealing sleeve into the corresponding hole to ensure the sealing of the connection. There are different types of sealing sleeve installation mechanisms in the industry. This sealing sleeve installation mechanism is for the installation of sealing sleeves in the four fixed holes on the automobile shift base. The sealing sleeve installation mechanism requires the sealing sleeves to be installed in the four fixed holes of the shift base at the same time. A special fixture is used to clamp and position the shift base of the same model on the workbench of the special fixture. The sealing sleeve is then installed in the four fixed holes of the shift base by using the vertical movement of the piston in the cylinder, avoiding manual installation of the four fixed holes individually, improving installation efficiency, and saving manpower.

[0003] When the existing sealing sleeve installation mechanism for the automobile shift base is working, the worker first places the shift base flat on the workbench, makes one end of the shift base rest against the positioning block, then manually tightens the clamping block to clamp and position the shift base, respectively places four sealing sleeves on the connecting columns of the stamping mechanism, adsorbs the sealing sleeves through a vacuum machine, and finally uses the piston movement of the cylinder to drive the movement of the stamping assembly to install the sealing sleeve in the fixing hole; the installation of the sealing sleeve requires first clamping the sealing sleeve and then using the cylinder to drive the stamping mechanism to install the sealing sleeve. In the process of clamping first and then stamping, the application of clamping force and the action of stamping force will cause the installation position to deviate, affecting the installation of the sealing sleeve, and then affecting the sealing performance of the sealing sleeve.

[0004] In view of this, and in response to the above-mentioned deficiencies, the present invention has developed a mounting mechanism for a sealing sleeve on a shift base. Summary of the Invention

[0005] The technical problem to be solved by the present invention is as follows: In the existing installation process of the sealing sleeve, a stamping mechanism is required to first position and clamp the sealing sleeve, and then the stamping mechanism is driven by the cylinder to slide in the vertical direction to achieve the installation of the sealing sleeve. In this process, due to the application of the clamping force and the subsequent action of the stamping force, the sealing sleeve will be offset in the installation position, affecting the installation of the sealing sleeve and further affecting the sealing performance of the sealing sleeve.

[0006] The present invention provides the following technical solutions: a mounting mechanism for a sealing sleeve on a shift base, comprising an air pump, a soft air tube, a stamping mechanism and a clamp; the air pump is fixedly mounted on a frame, a soft air tube is fixedly mounted on one end of the air pump, a stamping mechanism is fixedly mounted on one end of the soft air tube, the stamping mechanism is fixedly mounted on the frame, and a pressure difference is formed inside and outside the stamping mechanism when the air pump works, driving the stamping mechanism to slide in a vertical direction; a clamp is fixedly mounted below the stamping mechanism, the clamp is placed flat on the frame, the side of the clamp is connected to the air pump through the soft air tube, the clamp evacuates the gas in the clamp through the air pump, forms a negative pressure in the clamp, and firmly adsorbs the shift base on the clamp.

[0007] In order to ensure that the installation mechanism of the sealing sleeve on the shift base can operate normally, the most important thing is that the airtightness of the entire mechanism is good and there will be no air leakage, so the soft air pipe and each component adopt an interference fit; at the same time, to ensure that the sealing sleeve can be installed on the shift base, the stamping mechanism is directly above the fixture; in order to ensure the relative sliding between the stamping mechanism and the fixture, the stamping mechanism and the fixture adopt a clearance fit; in order to ensure that the entire mechanism can work safely, the fixture is fixedly installed on a flat workbench.

[0008] The stamping mechanism includes a fixed platform, a steel ball, a sealing ring, a sliding rod, a connecting platform, a stamping platform and a clamping column. The side of the fixed platform is fixedly installed on the frame, and the bottom of the fixed platform is fixedly installed with a steel ball and a sealing ring. Four sliding rods are slidably installed at the four corners of the upper surface of the fixed platform, and a connecting platform is fixedly installed in the middle of the sliding rod. Mounting through holes are opened at the four corners of the upper surface of the connecting platform, and four 30° fan-shaped grooves are arranged in a circular array in the middle of the mounting through holes. A stamping platform is fixedly installed in the middle of the connecting platform. The upper surface shape of the stamping platform should be the same as the shape formed by the four holes of the shift base where the sealing sleeves need to be installed. Four clamping columns are fixedly installed at the four corners of the upper surface of the stamping platform, and the four clamping columns are arranged directly above the four fixed holes of the sliding base.

[0009] When parts of the stamping mechanism are damaged, in order to ensure that the stamping mechanism can be disassembled and the damaged parts can be replaced, the fixed platform is bolted to the frame, and a clearance fit is adopted between the fixed platform and the slide bar, and a clearance fit is adopted between the slide bar and the stamping platform; in order to ensure that the clamping column of the clamping sealing sleeve can normally install the sealing sleeve on the shift base, the four clamping columns are arranged directly above the four fixing holes of the slide base, and in order to ensure rapid disassembly between the connecting platform and the slide bar, four 30° fan-shaped grooves are opened on the mounting through hole of the connecting platform; in order to save material costs, the shape of the upper surface of the stamping platform should be similar to the shape formed by the four holes of the shift base where the sealing sleeves need to be installed. In order to ensure that no parts of the stamping mechanism will be deformed after working for a period of time and to ensure work efficiency, the fixed platform, slide bar, connecting platform, stamping platform and clamping columns should all be made of carbide materials, such as tungsten steel, titanium alloy steel, etc.

[0010] An air inlet hole is provided on the upper surface of the fixing table, and four stepped holes are provided at the four corners of the lower surface of the fixing table. The ratio of the diameter of the stepped hole to the diameter of the air inlet hole is 1:2. A sealing groove and a ball groove are provided at one end of the four stepped holes, and a side hole is provided at the other end of the stepped hole. The side hole is connected to the air inlet hole and the stepped hole.

[0011] In order to ensure stable gas transmission between the air pump and the fixed platform, the air inlet holes opened on the surface of the fixed platform and the soft air pipe adopt an interference fit; in order to ensure that the fixed platform can be fixedly installed on the frame and will not be offset due to work, the fixed platform is fixed to the frame by bolts; in order to ensure stable airflow in the stepped holes and the air inlet holes in the fixed platform during work, the ratio of the diameter of the stepped holes to the diameter of the air inlet holes is 1:2. When the ratio of the diameter of the stepped holes to the diameter of the air inlet holes is greater than 1:2, it is impossible to ensure that the four stepped holes are compressed at the same time. When the ratio of the diameter of the stepped holes to the diameter of the air inlet holes is less than 1:2, the pressure in the stepped holes changes too quickly, resulting in too fast movement speed of the stamping mechanism, excessive impact load, and loss of part life.

[0012] A limiting cone is provided at both ends of the sliding rod, the diameter of the limiting cone is equal to the diameter of the fixed step hole, the middle annular array of the sliding rod has four mounting bosses, the sliding distance range of the sliding rod is 100-150mm, and the roughness of the side of the sliding rod must reach 1.6.

[0013] In order to ensure the stability of the sliding rod movement process, the side of the sliding rod should be as smooth as possible, and the roughness of the side of the sliding rod should reach 1.6; for easy installation, the diameter of the four mounting bosses of the circular array in the middle of the sliding rod is the same as the spacing between the four 30° fan-shaped grooves of the connecting platform; the sliding distance range of the sliding rod is 100-150mm. When the sliding distance of the sliding rod is less than 100mm, it is inconvenient to install the sealing sleeve. When the sliding distance of the sliding rod is greater than 150mm, the distance moved by the sliding rod in the positioning platform is too large, and the required height of the positioning platform must also be increased accordingly, which wastes materials.

[0014] A threaded through hole is provided on the upper surface of the stamping table, and the position relationship of the threaded through hole is consistent with the position relationship of the four fixing holes of the shift base. A ventilation boss is provided at the center of the lower surface of the stamping table, and an air suction hole is provided on the side of the ventilation boss. A connecting blind hole is provided at the bottom of the ventilation boss. The connecting blind hole of the ventilation boss is connected to the air suction hole of the ventilation boss, and the ratio of the diameter of the connecting blind hole of the connecting block to the diameter of the air suction hole of the connecting block is 2:1.

[0015] In order to ensure that the sealing sleeve can be installed in the fixing hole of the shift base, the upper surface of the stamping table is provided with a threaded through hole that is consistent with the position relationship of the four fixing holes of the shift base; one end of the suction hole is connected to the inverted L-shaped holes of the two clamping columns through a soft air pipe, and the other end of the suction hole of the stamping table is connected to the inverted L-shaped holes of the other two clamping columns through a soft air pipe. In order to ensure the stability of the suction force in the soft air pipe and the stamping table, the diameter of the suction hole of the stamping table should be twice the diameter of the inverted L-shaped column of the clamping column. When the diameter of the suction hole of the stamping table is greater than twice the diameter of the inverted L-shaped column of the clamping column When the diameter of the air suction hole of the stamping table is less than twice the diameter of the inverted L-shaped column of the clamping column, it will cause a part of the power of the air pump to be wasted. When the diameter of the air suction hole of the stamping table is less than twice the diameter of the inverted L-shaped column of the clamping column, it will cause the inability to form a negative pressure environment and the clamping of the clamping column cannot be guaranteed. The ratio of the diameter of the connecting blind hole of the stamping table to the diameter of the air suction hole of the stamping table is 2:1. When the ratio of the diameter of the connecting blind hole of the stamping table to the diameter of the air suction hole of the stamping table is less than 2:1, it will cause the stamping table to be unable to form a negative pressure environment. When the ratio of the diameter of the connecting blind hole of the stamping table to the diameter of the air suction hole of the stamping table is greater than 2:1, it will cause a part of the power of the air pump to be wasted.

[0016] A clamping cone is provided at one end of the clamping column, the diameter of the clamping cone is the same as the diameter of the center hole of the sealing sleeve, a clamping through hole is provided on the side of the clamping cone, and an inverted L-shaped hole is provided on the middle side of the clamping column, the inverted L-shaped hole is connected to the clamping through hole of the fixture cone, the diameter of the inverted L-shaped hole of the clamping column is twice the diameter of the clamping through hole of the cone, and the length range of the clamping column is 100-150mm.

[0017] In order to ensure that the clamping column and the mounting table are detachable, the clamping column and the mounting table are connected by a thread. A thread is provided at one end of the clamping column, and the length of the thread should be consistent with the thickness of the mounting table. In order to ensure that the clamping column can realize the clamping function of the sealing sleeve, the diameter of the inverted L-shaped hole is twice the diameter of the clamping through hole of the clamping table. When the diameter of the inverted L-shaped hole is larger than twice the diameter of the clamping through hole of the clamping table, the suction force in the inverted L-shaped hole is excessive, resulting in waste of vacuum machine power. When the diameter of the inverted L-shaped hole is smaller than twice the diameter of the clamping through hole of the clamping table, the suction force in the inverted L-shaped hole is too small to achieve clamping of the sealing sleeve. In order to cooperate with the installation of the sealing sleeve, the length range of the clamping column is 100-150mm. When the length of the clamping column is less than 100mm, the gap between the clamping column and the fixture is too small, which is inconvenient for the installation of the sealing sleeve.

[0018] The clamp includes a clamp body, a positioning block, a column and a gasket. The clamp body is fixedly installed on a plane. Two positioning blocks are fixedly installed on the upper surface of the clamp body in a mirror image of the clamp body. The positioning blocks have the same shape as the two corners on one side of the shift base. Four columns are fixedly installed on the upper surface of the clamp body. The four columns are evenly arranged on both sides of the upper surface of the clamp body. The columns are slidably connected to the stamping mechanism, and a gasket is fixedly installed on one end of the column.

[0019] In order to ensure the integrity and detachability of the clamp, the mirror screws of the positioning block are installed on both sides of the upper surface of the clamp body. The clamp body is connected to the four columns through threads. The diameter of the center hole of the gasket is consistent with the diameter of the column, and the diameter of the gasket is twice the diameter of the column. The gasket and the column adopt an interference fit to ensure that the gasket can fit completely on the column; in order to ensure that the shift base can be installed on the clamp, the four columns are evenly arranged on both sides of the upper surface of the clamp body; in order to ensure the accuracy of installation, the clamp body should be made of carbide materials, such as tungsten steel, titanium alloy, etc.

[0020] Four connecting through holes are evenly arranged on the upper surface of the clamp body, and the four connecting through holes are provided with threads. The diameter of the four connecting through holes is the same as the diameter of the column. The upper surface of the clamp body is provided with 16 clamping blind holes, and the 16 clamping blind holes are arranged in 4 rows and 4 columns. Four ventilation blind holes are provided on the side of the clamp body, and the ventilation blind holes are connected with the clamping blind holes. The ratio of the diameter of the ventilation blind hole to the diameter of the clamping blind hole is 2:1.

[0021] The clamp uses pressure difference to clamp the shift base. The clamp body is the most important workpiece in the clamp. The upper surface of the clamp body must be flat and without inclination. In order to ensure that the shift base can be clamped, 16 clamping blind holes are opened on the upper surface of the clamp body. The clamping blind holes are arranged in 4 rows and 4 columns, of which two rows of clamping blind holes are arranged in the front half of the shift base, and the other two rows of clamp blind holes are arranged in the back half of the shift base. In order to connect each row of clamping blind holes, a ventilation blind hole is opened on one side of the clamp body. At the same time, in order to ensure the negative pressure environment in the ventilation blind hole and the clamping blind hole during operation, the ratio of the diameter of the ventilation blind hole to the diameter of the clamping blind hole is 2:1. The clamp body should be made of cemented carbide materials such as tungsten steel, titanium alloy, etc.

[0022] The column and the sliding rod are clearance-fitted, the length range of the column is 150-200 mm, a limiting hole is provided at one end of the column, the diameter of the limiting hole is the same as the diameter of the sliding rod, and a sliding hole is provided at the other end of the column, the diameter of the sliding hole is the same as the diameter of the limiting cone of the sliding rod, and the sliding hole is connected to the limiting hole.

[0023] The column should be made of high-strength materials such as aluminum alloy, ceramic alloy, etc., and should be processed by casting; in order to ensure that the stamping mechanism can move 100-150mm, the length range of the column is 150-200mm. When the length of the column is less than 150mm, the movement distance of the stamping mechanism cannot be guaranteed. When the length of the column is greater than 200mm, material is wasted; in order to ensure that the slide rod slides in the limit hole of the column, the diameter of the limit hole is the same as the diameter of the slide rod, and the diameter of the slide hole is the same as the diameter of the limit cone of the slide rod.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The present invention provides a stamping mechanism directly above the shift base, and forms a negative pressure environment by pumping air through an air pump, so that the stamping mechanism can complete the downward movement of the stamping mechanism while clamping and positioning the four sealing sleeves, helping to solve the problem of clamping the sealing sleeves and the movement power of the stamping mechanism, and improving the work efficiency of installing the sealing sleeves on the automobile shift base.

[0026] 2. The present invention connects one end of the clamp and one end of the stamping mechanism with one end of the air pump at the same time, and uses the pressure difference formed by the air pump to clamp the shift base on the clamp and the sealing sleeve on the stamping mechanism, thereby helping to achieve simultaneous and rapid clamping and positioning of the shift base and the sealing sleeve, thereby improving work efficiency.

[0027] 3. The present invention enables the stamping mechanism to slide relative to the clamp in the vertical direction by slidingly connecting the upper end of the clamp with the stamping mechanism and communicating the right end of the clamp with the air pump, thereby helping the stamping mechanism to complete the stamping process, and the clamp can utilize the air pump's suction to achieve positioning and clamping of the shift base.

DETAILED DESCRIPTION

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0042] like Figure 1 As shown, a mounting mechanism for a sealing sleeve on a shift base comprises an air pump 1, a soft air tube 2, a stamping mechanism 3 and a clamp 4; the air pump 1 is fixedly mounted on a machine frame, a soft air tube 2 is fixedly mounted on one end of the air pump 1, a stamping mechanism 3 is fixedly mounted on one end of the soft air tube 2, the stamping mechanism 3 is fixedly mounted on the machine frame, and a pressure difference is formed inside and outside the stamping mechanism 3 when the air pump 1 works, driving the stamping mechanism 3 to slide in a vertical direction; a clamp 4 is fixedly mounted below the stamping mechanism 3, and the clamp 4 is placed flat on a workbench, and the side of the clamp 4 is connected to the air pump 1 through the soft air tube 2, and the clamp 4 evacuates the gas in the clamp 4 through the air pump 1, thereby forming a negative pressure in the clamp 4, and firmly adsorbing the shift base on the clamp 4.

[0043] The soft air pipe 2 is interference fit with each component, the stamping mechanism 3 is located directly above the fixture 4, and a clearance fit is used between the stamping mechanism 3 and the fixture 4. The fixture 4 is fixedly mounted on a flat workbench. When the mechanism starts working, the worker first places the shift base on the fixture 4 to complete the positioning of the shift base. After that, the worker installs the four sealing sleeves on the stamping mechanism 3, and the air pump 1 draws air to form a negative pressure environment in the stamping mechanism 3 and the fixture 4, which helps the fixture 4 to clamp the shift base and helps the stamping mechanism 3 to achieve The four sealing sleeves are clamped; at the same time, the output end of the cylinder discharges the gas into the stamping mechanism 3, and the pressure difference in the stamping mechanism 3 drives the stamping mechanism 3 to move downward. The downward movement of the stamping mechanism 3 drives the sealing sleeve to move downward, and the sealing sleeve enters the fixed hole in the shift base, completing the installation of the sealing sleeve; finally, the air pump 1 reverses the air pumping, the stamping mechanism 3 no longer clamps the sealing sleeve, the stamping mechanism 3 returns to its original position, and the clamp 4 no longer clamps the shift base, completing the installation of the sealing sleeve on the shift base.

[0044] like Figure 2 、 Figure 3 and Figure 7 As shown, the stamping mechanism 3 includes a fixed platform 31, a steel ball 32, a sealing ring 33, a sliding rod 34, a connecting platform 35, a stamping platform 36 and a clamping column 37. The side of the fixed platform 31 is fixedly mounted on the frame, and the bottom of the fixed platform 31 is fixedly mounted with a steel ball 32 and a sealing ring 33. Four sliding rods 34 are slidably mounted at the four corners of the upper surface of the fixed platform 31, and a connecting platform 35 is fixedly mounted in the middle of the sliding rod 34. Mounting through holes 351 are opened at the four corners of the upper surface of the connecting platform 35, and four 30° fan-shaped grooves 352 are arranged in a circular array in the middle of the mounting through holes 351. A stamping platform 36 is fixedly mounted in the middle of the connecting platform 35. The upper surface shape of the stamping platform 36 should be the same as the shape formed by the four holes of the shift base where the sealing sleeves need to be installed. Four clamping columns 37 are fixedly mounted at the four corners of the upper surface of the stamping platform 36. The four clamping columns 37 are arranged directly above the four fixed holes of the sliding base.

[0045] The fixed platform 31 is bolted to the frame, and a clearance fit is adopted between the fixed platform 31 and the slide bar 34, and a clearance fit is adopted between the slide bar 34 and the stamping platform 36. The shape of the upper surface of the stamping platform 36 should be similar to the shape formed by the four holes of the shift base where the sealing sleeves need to be installed. In order to ensure that no parts of the stamping mechanism 3 will be deformed after working for a period of time and to ensure work efficiency, the fixed platform 31, the slide bar 34, the connecting platform 35, the stamping platform 36 and the clamping column 37 should all be made of hard alloy tungsten steel.

[0046] When the stamping mechanism 3 starts working, the suction end of the air pump 1 draws away the air in the holes of the clamping column 37 and the stamping table 36, forming a negative pressure in the clamping column 37 and the connecting block, and the clamping column 37 clamps the sealing sleeve. Afterwards, the air outlet end of the air pump 1 outputs the gas to the fixed platform 31, and the gas gathers in the fixed platform 31, so that a pressure difference is formed between the inside and outside of the fixed platform 31. The slide rod 34 slides downward under the drive of the pressure difference, and the slide rod 34 slides downward to drive the connecting platform 35 to slide downward. The downward movement of the connecting platform 35 pushes the clamping column 37 and the connecting block to move downward together. When the installation of the sealing sleeve on the shift base is completed, the suction port of the air pump 1 becomes the air outlet, and the holes in the fixed block, clamping column 37 and stamping table 36 restore the air pressure. The clamping column 37 no longer clamps the sealing sleeve, and the slide rod 34 drives the connecting platform 35, the stamping table 36 and the clamp 4 columns to return to their original positions.

[0047] like Figure 5 As shown, an air inlet hole 311 is formed on the upper surface of the fixing platform 31, and four stepped holes 312 are formed at the four corners of the lower surface of the fixing platform 31. The ratio of the diameter of the stepped hole 312 to the diameter of the air inlet hole 311 is 1:2. A sealing groove 313 and a ball groove 314 are formed at one end of the four stepped holes 312, and a side hole 315 is formed at the other end of the stepped hole 312. The side hole 315 is connected to the air inlet hole 311 and the stepped hole 312.

[0048] The air inlet hole 311 opened on the upper surface of the fixed platform 31 adopts an interference fit with the soft air pipe 2. The fixed platform 31 is fixedly mounted on the frame by bolts. The ratio of the diameter of the stepped hole 312 to the diameter of the air inlet hole 311 is 1:2. The fixed platform 31 is made of cemented carbide tungsten steel. When the mechanism starts working, the air outlet of the air pump 1 discharges gas into the air inlet hole 311 of the fixed platform 31, and the gas enters the stepped hole 312 through the side hole 315. High pressure is formed in the stepped hole 312, and the slide rod 34 slides downward under the action of the high pressure. After the sealing sleeve on the shift base is installed, the air pump 1 removes the gas in the stepped hole 312, and the slide rod 34 returns to its original position under negative pressure. At this time, the installation of the sealing sleeve on the shift base is completed.

[0049] like Figure 6 As shown, a limiting cone 341 is provided at both ends of the slide rod 34, and the diameter of the limiting cone 341 is equal to the diameter of the stepped hole 312 of the fixed platform 31. The middle annular array of the slide rod 34 has four mounting bosses 342. The sliding distance range of the slide rod 34 is 100 mm, and the roughness of the side of the slide rod 34 must reach 1.6.

[0050] The roughness of the side of the sliding rod 34 must reach 1.6. The diameter of the four mounting bosses 342 of the middle annular array of the sliding rod 34 is the same as the spacing between the four 30° fan-shaped grooves 352 of the connecting platform 35. The sliding distance of the sliding rod 34 is 100 mm. The sliding rod 34 completes the vertical sliding under the action of air pressure. The sliding rod 34 is made of cemented carbide tungsten steel material.

[0051] like Figure 8 As shown, a threaded through hole 361 is provided on the upper surface of the stamping platform 36, and the position relationship of the threaded through hole 361 is consistent with the position relationship of the four fixing holes of the shift base. A ventilation boss 362 is provided at the center of the lower surface of the stamping platform 36, and an air intake hole 363 is provided on the side of the ventilation boss 362. A connecting blind hole 364 is provided at the bottom of the ventilation boss 362. The connecting blind hole 364 of the ventilation boss 362 is connected to the air intake hole 363 of the ventilation boss 362, and the ratio of the diameter of the connecting blind hole 364 of the connecting block to the diameter of the air intake hole 363 of the connecting block is 2:1.

[0052] The upper surface of the stamping platform 36 is provided with a threaded through hole 361 which is consistent with the position relationship of the four fixing holes of the shift base. The diameter of the air intake hole 363 of the stamping platform 36 should be twice the diameter of the inverted L-shaped column of the clamping column 37. The thickness of the stamping platform 36 is 30 mm. The stamping platform 36 is made of carbide tungsten steel material. The stamping platform 36 is fixedly connected to the connecting platform 35, and the connecting platform 35 drives the stamping platform 36 to move in the vertical direction.

[0053] like Figure 9 As shown, a clamping cone 371 is provided at one end of the clamping column 37, and the diameter of the clamping cone 371 is the same as the diameter of the center hole of the sealing sleeve. A clamping through hole 372 is provided on the side of the clamping cone 371, and an inverted L-shaped hole 373 is provided on the middle side of the clamping column 37. The inverted L-shaped hole 373 is connected to the clamping through hole 372 of the clamp cone 371. The diameter of the inverted L-shaped hole 373 of the clamping column 37 is twice the diameter of the clamping through hole 372 of the cone, and the length of the clamping column 37 is 100 mm.

[0054] The clamping column 37 is connected to the mounting table by a threaded connection. The thread length of the clamping column 37 should be consistent with the thickness of the mounting table. The diameter of the inverted L-shaped hole 373 is twice the diameter of the clamping through hole 372 of the clamping cone 371. The diameter of the clamping column 37 is the same as the maximum diameter of the sealing sleeve. The clamping column 37 is made of carbide tungsten steel. When the stamping mechanism 3 starts to move, the vacuum machine draws out the air in the clamping through hole 372 and the inverted L-shaped hole 373 in the clamping column 37 through the soft air pipe 2, and forms a vacuum in the clamping through hole 372 and the inverted L-shaped hole 373 of the clamping column 37 to help the clamping column 37 clamp the sealing sleeve. Then the clamping column 37 moves downward with the stamping mechanism 3 to install the sealing sleeve on the shift base. After the installation is completed, the vacuum machine stops working, the clamping column 37 no longer clamps the sealing sleeve, and the clamping column 37 follows the stamping mechanism 3 to reset and perform the next installation work.

[0055] like Figure 4 As shown, the clamp 4 includes a clamp body 41, a positioning block 42, a column 43 and a gasket 44. The clamp body 41 is fixedly installed on a plane. Two positioning blocks 42 are fixedly installed on the upper surface of the clamp body in a mirror image of the clamp body. The positioning blocks 42 are consistent in shape with the two corners on one side of the shift base. Four columns 43 are fixedly installed on the upper surface of the clamp body 41. The four columns 43 are evenly arranged on both sides of the upper surface of the clamp body 41. The columns 43 are slidably connected to the stamping mechanism 3. A gasket 44 is fixedly installed on one end of the column 43.

[0056] The mirror screws of the positioning block 42 are installed on both sides of the upper surface of the clamp body 41. The clamp body 41 is connected to the four columns 43 by threads. The diameter of the center hole of the gasket 44 is consistent with the diameter of the column 43, and the diameter of the gasket 44 is twice the diameter of the column 43. The gasket 44 and the column 43 adopt an interference fit. The clamp body 41 should be made of cemented carbide tungsten steel material. When the clamp 4 starts working, the air pump 1 evacuates the air in the hole of the clamp body 41 through the soft air pipe 2 to form a negative pressure environment. The clamp body 41 clamps the shift base and positions it. The stamping mechanism 3 starts to move downward. When the connecting platform 35 in the stamping mechanism 3 contacts the gasket 44, the air pump 1 inputs gas into the clamp 4, and the clamp 4 no longer clamps the shift base. The stamping mechanism 3 completes its work and returns to its original position to complete the work on the sealing sleeve on a shift base.

[0057] like Figure 10As shown, four connecting through holes 411 are evenly provided on the upper surface of the clamp body 41, and the four connecting through holes 411 are provided with threads. The diameter of the four connecting through holes 411 is the same as the diameter of the column 43. The upper surface of the clamp body 41 is provided with 16 clamping blind holes 412, and the 16 clamping blind holes 412 are arranged in 4 rows and 4 columns. Four ventilation blind holes 413 are provided on the side of the clamp body 41, and the ventilation blind holes 413 are connected to the clamping blind holes 412. The ratio of the diameter of the ventilation blind hole 413 to the diameter of the clamping blind hole 412 is 2:1.

[0058] The upper surface of the clamp body 41 must be flat and without an inclination. There are 16 clamping blind holes 412 on the upper surface of the clamp body 41, and the clamping blind holes 412 are arranged in 4 rows and 4 columns, of which two rows of clamping blind holes 412 are arranged in the front half of the shift base, and the other two rows of clamp 4 blind holes are arranged in the back half of the shift base. The ratio of the diameter of the ventilation blind hole 413 to the diameter of the clamping blind hole 412 is 2:1, and the clamp body 41 is made of cemented carbide tungsten steel material; when the clamp 4 starts working, the air in the hole of the clamp body 41 is extracted through a vacuum machine, so that a pressure difference is formed between the hole of the clamp body 41 and the outside, thereby clamping the shift base. When the installation of the sealing sleeve on the shift base is completed, the vacuum machine stops working, air enters the clamp body 41, the pressure difference between the inside and outside of the clamp body 41 disappears, and the clamp body 41 no longer clamps the shift base.

[0059] like Figure 11 As shown, the column 43 and the slide rod 34 are clearance-fitted, the length of the column 43 is 150 mm, a limiting hole 431 is provided at one end of the column 43, the diameter of the limiting hole 431 is the same as the diameter of the slide rod 34, and a sliding hole 432 is provided at the other end of the column 43, the diameter of the sliding hole 432 is the same as the diameter of the limiting cone 341 of the slide rod 34, and the sliding hole 432 is connected to the limiting hole 431. The column 43 should be made of high-strength aluminum alloy material and should be processed by casting. The diameter of the limiting hole 431 is the same as the diameter of the slide rod 34, and the diameter of the sliding hole 432 is the same as the diameter of the limiting cone 341 of the slide rod 34. The function of the column 43 is mainly to allow the slide rod 34 to move within the fixed track. At the same time, the column 43 and the slide rod 34 adopt a clearance fit to ensure that the gas in the sliding hole 432 of the column 43 can go out through the gap between the slide rod 34 and the column 43, so as to ensure that the movement of the slide rod 34 will not be subject to too much resistance.

[0060] When the installation mechanism of the sealing sleeve on the shift base starts to work, the worker first places the shift base on the fixture 4, and one side of the shift base fits into the positioning block 42. Then the worker installs the four sealing sleeves on the clamping column 37 of the stamping mechanism 3, and the air pump 1 starts to pump air, forming a negative pressure environment in the clamping column 37 of the stamping mechanism 3 and the clamping body 41 of the fixture 4, helping the stamping mechanism 3 to clamp the four sealing sleeves and helping the fixture 4 to clamp the shift base; when the shift base and the sealing sleeve are both clamped and positioned, the stamping mechanism 3 also starts to work, and the air outlet end of the air pump 1 outputs gas to the fixed platform 3 1, gas gathers in the fixed platform 31, forming a pressure difference between the inside and outside of the fixed platform 31, and the slide rod 34 slides downward under the drive of the pressure difference, and the downward sliding of the slide rod 34 drives the connecting platform 35 to slide downward, and the downward movement of the connecting platform 35 pushes the clamping column 37 and the connecting block to move downward together. When the installation of the sealing sleeve on the shift base is completed, the air intake of the air pump 1 becomes the air outlet, and the holes in the fixed block, the clamping column 37 and the punching platform 36 restore the air pressure. The clamping column 37 no longer clamps the sealing sleeve, and the slide rod 34 drives the connecting platform 35, the punching platform 36 and the clamp 4 columns to return to their original positions.
