Description

Technical Field

[0001] The present invention relates to the technical field of brake assembly, and particularly to a cylinder barrel and piston assembly device for a multi-process series-connected brake. Background Art

[0002] Brakes are divided into disc brakes and drum brakes. Inside both disc brakes and drum brakes, there are parts such as cylinder barrels and pistons. Brake fluid is used to push the pistons to move, so that the brake pads cooperate with the wheels to generate a braking effect.

[0003] In the prior art, when assembling the parts of the cylinder barrel and the piston, separate feeding is required for each. This means that each feeding operation needs to be carried out separately, which not only consumes a large amount of time, but also increases the possibility of more human errors due to the increase in operation steps. At the same time, there is a lack of effective integration and connection between each link, resulting in a long production process and the inability of the equipment to operate in an efficient collaborative manner. This separate feeding operation method is difficult to meet the growing market demand and the enterprise's pursuit of efficient production, and greatly limits the production scale and delivery speed of related products.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, the three key processes of cylinder barrel feeding, docking of the cylinder barrel and the piston, and airtightness detection of the inner cavity of the cylinder barrel are connected in series.

[0017] 3. In the present invention, the cylinder barrel is ejected by the bidirectional ejection mechanism, enabling the cylinder barrel to be docked with the piston inside the docking and assembling mechanism. At the same time, the bidirectional ejection mechanism also drives the sliding rod to reciprocate, cooperating with the one-way valve plate and the filter screen, enabling the gas storage pipe to continuously convey filtered high-pressure air to the exhaust pipe, conducting a reliable airtightness test on the cavity of the cylinder barrel, promptly detecting and eliminating products with poor airtightness, and guaranteeing the product quality.

[0018] 4. In the present invention, the position of the moving ring can be flexibly controlled through the double-output shaft cylinder and the single-output shaft cylinder, and the diameter of the inward clamping of the internal positioning component can be adjusted to adapt to different outer diameters of the cylinder barrel and the piston. At the same time, by controlling the working frequencies of the double-output shaft cylinder, the single-output shaft cylinder and the synchronous transmission mechanism, the synchronous feeding and docking of the cylinder barrel and the piston are achieved, significantly improving the working efficiency of the series assembly.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: According to Figure 1 - Figure 17 As shown, a cylinder barrel and piston assembly device for a multi-process series type brake includes a cylinder barrel feeding mechanism 1, an air supply mechanism 3, and a piston feeding mechanism 4. The cylinder barrel feeding mechanism 1 is used to convey cylinder barrels one by one, and the piston feeding mechanism 4 is used to convey pistons one by one. A docking and assembling mechanism 5 is arranged between the two; an air supply mechanism 3 is arranged on the other side of the cylinder barrel feeding mechanism 1 for supplying air into the cavity of the cylinder barrel; the docking and assembling mechanism 5 is used for one-to-one assembly of the cylinder barrel and the piston; a bidirectional ejection mechanism 2 is arranged outside the cylinder barrel feeding mechanism 1.

[0023] The bidirectional ejection mechanism 2 includes a U-shaped seat 21, a rotating shaft 23 is rotatably connected at the center of the U-shaped seat 21, an eccentric disc core 24 is fixedly connected to the top of the rotating shaft 23, a sleeve disc 25 is rotatably sleeved on the outer wall of the eccentric disc core 24, and a disc shell 26 is rotatably connected to the outer wall of the sleeve disc 25. Sliding columns 22 are slidably connected at both ends of the U-shaped seat 21, and one end of the sliding column 22 is fixedly connected to the disc shell 26. One of the sliding columns 22 pushes the cylinder barrel and the piston to be pressed tightly, and the other sliding column 22 is used to push the sealing plug 35 in the air supply mechanism 3 to inflate.

[0024] The cylinder feeding mechanism 1 includes a pedestal 11, and blocks 110 are evenly distributed on the upper surfaces of both sides of the pedestal 11. One end of the pedestal 11 is fixedly connected to an inclined plate 13, and the other end of the pedestal 11 is fixedly connected to an inclined plate 2 14. A transport component 15 is arranged inside the pedestal 11. The transport component 15 includes a strip 151 and two fixed seats 155. The fixed seats 155 are installed inside the pedestal 11 through support columns. The inner side wall of the fixed seat 155 is rotatably connected to a rotating shaft 154, and one end of the rotating shaft 154 is fixedly connected to a rotating rod 153. The two ends of the strip 151 are rotatably connected to the two rotating rods 153 respectively, and circular recesses 152 are evenly spaced at the top of the strip 151. The transport component 15 transports the cylinders on the block 110 forward one by one.

[0025] A synchronous transmission mechanism 6 is arranged between the transport component 15 and the rotating shaft 23. The synchronous transmission mechanism 6 includes a bevel gear 1 61, a bevel gear 2 62, a belt mechanism 63 and a servo motor 3 64. The bevel gear 1 61 is fixedly connected to one of the rotating shafts 1 154. The bevel gear 2 62 and the bevel gear 1 61 are meshed with each other. The servo motor 3 64 is installed on the ground, and the output end of the servo motor 3 64 is fixedly connected to the bottom surface of the bevel gear 2 62. The bevel gear 2 62 and the rotating shaft 2 23 are transmission-connected by a belt mechanism 63.

[0026] The processes involved in brake assembly include: cylinder loading, piston loading, cylinder and piston docking, cylinder and piston pressing, and cylinder inner cavity air tightness test. This equipment is used for brake assembly with straight cylinder. This equipment is installed on the ground. This equipment connects the three processes of cylinder loading, cylinder and piston docking, and cylinder inner cavity air tightness test in series to ensure the orderliness and consistency of the process.

[0027] The principle of feeding the cylinder barrel is as follows: After the cylinder barrel is manufactured, a batch of cylinder barrels are transported by a conveyor belt to the second inclined plate 14. After the cylinder barrels reach the second inclined plate 14, they roll down along the inclined surface and are limited by the clamping blocks 110 at one end. Multiple cylinder barrels are stacked on the upper surface of the second inclined plate 14. The servo motor three 64 drives the bevel gear two 62 to rotate, and then the bevel gear two 62 drives the bevel gear one 61 to rotate. The bevel gear one 61 drives the rotating shaft one 154 to continuously rotate. The rotating shaft one 154 drives the rotating rod 153 to rotate, and the rotating rod 153 drives the strip plate 151 to move within a circular running track. The other end of the strip plate 151 is limited by another rotating rod 153, so that the strip plate 151 always remains parallel to the ground when moving. When the strip plate 151 moves to the upper half of the circumferential track, the circular concave seat 152 contacts the cylinder barrels stacked on one side of the pedestal 11 and transports the cylinder barrels forward one by one. When the strip plate 151 moves to the lower half of the circumferential track, the circular concave seat 152 separates from the transported cylinder barrels. Each time the circular concave seat 152 contacts a cylinder barrel, the cylinder barrel can be moved forward by one position until the cylinder barrel is moved to the position of the first inclined plate 13. The cylinder barrel rolls down along the inclined surface of the first inclined plate 13 and finally stops rolling at the groove seat 12, completing the process of feeding the cylinder barrels one by one; The principle of docking the cylinder barrel and the piston is as follows: The cylinder barrel and the piston are located on both sides of the docking and assembling mechanism 5. It is necessary to position the cylinder barrel and the piston to ensure that they are on the same axis. The function of the double-directional ejection mechanism 2 is to push the outer cylinder barrel into the interior of the docking and assembling mechanism 5, so that the internal structure of the docking and assembling mechanism 5 positions it. The output end of the servo motor three 64 drives the belt mechanism 63 to operate, so that the belt mechanism 63 drives the rotating shaft two 23 to continuously rotate. The top of the rotating shaft two 23 is installed at a position deviating from the center of the eccentric disc core 24. The distance between the rotating shaft two 23 and the center of the eccentric disc core 24 is a fixed value, and the distance between the eccentric disc core 24 and the center of the disc shell 26 is also a fixed value. These two distances can be regarded as a connecting rod structure. When the rotating shaft two 23 drives the eccentric disc core 24 to rotate, the included angle of the connecting rod continuously changes. When the included angle of the connecting rod is zero degrees, the distance between the rotating shaft two 23 and the center of the sleeve disc 25 is the closest; when the included angle of the connecting rod is 180 degrees, the distance between the rotating shaft two 23 and the center of the sleeve disc 25 is the farthest. Every time the rotating shaft two 23 rotates one week, the included angle of the connecting rod is in the 180-degree state twice. At this time, the disc shell 26 moves to the outermost sides of both sides of the U-shaped seat 21 and is pushed outwards through the sliding columns 22 at both ends, so that one of the sliding columns 22 pushes the cylinder barrel into the interior of the docking and assembling mechanism 5 to complete the assembly and docking; The principle of airtightness detection of the inner cavity of the cylinder barrel is as follows: After the servo motor three 64 drives the double-directional ejection mechanism 2 to push left and right, the sliding column 22 at the other end pushes the sliding rod 31 to reciprocate. The air supply mechanism 3 continuously replenishes air into the conduit. After the cylinder barrel and the piston are assembled, it is used to test the airtightness of the cylinder cavity.

[0028] Example two: According to Figure 1 、Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown in Figure 11 , Figure 12 , Figure 13 and Figure 14 , the air supply mechanism 3 includes a sliding rod 31, an exhaust pipe 32, an intake pipe 33 and a gas storage pipe 34. The sliding rod 31 is slidably connected to the gas storage pipe 34. One end of the sliding rod 31 is fixedly connected to a sealing plug 35. The sealing plug 35 is slidably connected to the inner side wall of the gas storage pipe 34. The sliding rod 31 is fixedly connected to one of the sliding columns 22. Both sides of the exhaust pipe 32 and the intake pipe 33 are provided with two openings. The exhaust pipe 32 and the intake pipe 33 are respectively located on both sides of the gas storage pipe 34. The two openings of the exhaust pipe 32 and the intake pipe 33 are both communicated with the gas storage pipe 34, and a one-way valve piece 36 is provided at each opening position. One end of the exhaust pipe 32 is communicated with a conduit. The exhaust pipe 32 ventilates the cylinder to be tested through the conduit. One end of the intake pipe 33 is fixedly connected with a filter screen.

[0029] In this embodiment, referring to the description of the attached Figure 12 When the sliding rod 31 is pushed out to the left, the cavity space on the left side shrinks, the air pressure increases, so that the one-way valve piece 36 in the upper left is opened, and the gas is discharged from the gas storage pipe 34 to the exhaust pipe 32; the cavity space on the right side increases, the air pressure decreases, so that the one-way valve piece 36 in the lower right is opened, and the gas is supplemented from the intake pipe 33 to the gas storage pipe 34. When the sliding rod 31 retracts to the right, the cavity space on the left side increases, the air pressure decreases, so that the one-way valve piece 36 in the lower left is opened, and the gas is supplemented from the intake pipe 33 to the gas storage pipe 34; the cavity space on the right side shrinks, the air pressure increases, so that the one-way valve piece 36 in the upper right is opened, and the gas is discharged from the gas storage pipe 34 to the exhaust pipe 32.

[0030] During the reciprocating movement of the sliding column 22 driving the sliding rod 31, the intake pipe 33 continuously supplements air to the gas storage pipe 34, the gas storage pipe 34 continuously discharges air to the exhaust pipe 32, the conduit collects the air in the exhaust pipe 32 and fills it into the tank body. The air pipe of the tank body is connected to a spray gun, and high-pressure gas is ejected from the spray gun mouth and communicated with the inner cavity of the cylinder through the oil inlet of the cylinder. Before the air enters the gas storage pipe 34, the dust is filtered by the filter screen on the intake pipe 33 to avoid blockage of the air supply mechanism 3 and the cylinder.

[0031] Embodiment 3: According to Figure 1 , Figure 4 , Figure 5 and Figure 6As shown in the figure, the piston loading mechanism 4 includes a first circular plate 41, a second circular plate 42, and a six-hole turntable 43. Brackets are fixedly connected to the outer sides of the first circular plate 41 and the second circular plate 42. The first circular plate 41 and the second circular plate 42 are installed on the ground through the brackets. The six-hole turntable 43 is located between the first circular plate 41 and the second circular plate 42, and the six-hole turntable 43 is rotatably connected to both the first circular plate 41 and the second circular plate 42. Through holes are provided on the surfaces of the first circular plate 41 and the second circular plate 42. A first conduit 44 is fixedly connected to the top surface of the first circular plate 41 at the position of the through hole, and a second conduit 45 is fixedly connected to the bottom surface of the second circular plate 42 at the position of the through hole. The bottom end of the second conduit 45 is on the same axis as the docking and assembling mechanism 5.

[0032] A intermittent rotation assembly 46 is provided below the bottom end of the second circular plate 42. The intermittent rotation assembly 46 includes a first gantry 464. A six-leg frame 463 is rotatably connected to the central position of the first gantry 464. The top end of the six-leg frame 463 penetrates through the second circular plate 42 and is fixedly connected to the bottom surface of the six-hole turntable 43. A first servo motor 461 is installed at the bottom end of the first gantry 464. The output end of the first servo motor 461 is fixedly connected to a first turntable 462, and the first turntable 462 drives the six-leg frame 463 to rotate intermittently.

[0033] A flipping assembly 47 is provided below the bottom end of the second conduit 45. The flipping assembly 47 includes a second gantry 472. A second servo motor 471 is installed on the outer side wall of the second gantry 472. The output end of the second servo motor 471 is fixedly connected to a second turntable 473. A four-leg frame 474 is rotatably connected to the side wall of the second gantry 472. The second turntable 473 is used to drive the four-leg frame 474 to rotate intermittently. One end of the four-leg frame 474 is fixedly connected to a flipping frame 475. A cylinder 477 is installed on the docking and assembling mechanism 5. The output end of the cylinder 477 is fixedly connected to a push-pull plate 476, and the push-pull plate 476 is used to move the piston on the flipping frame 475 into the docking and assembling mechanism 5.

[0034] In this embodiment, the outer shape of the cylinder barrel is a cylinder, and the outer shape of the piston is a disc structure. Affected by the respective structures of the cylinder barrel and the piston, the cylinder barrel can be loaded in a rolling state. When transporting the piston, it is put into the first conduit 44 and slides down in the first conduit 44 under the action of gravity, and falls into a circular hole of the six-hole turntable 43 from the through hole of the first circular plate 41.

[0035] In order to drive the six-hole turntable 43 to rotate intermittently so as to run the pistons one by one into the conduit 2 45, an intermittent rotation component 46 is arranged below the circular plate 2 42, and a servo motor 461 is installed below the gantry 464. The servo motor 461 directly drives the turntable 462 to rotate. Every time the turntable 462 rotates one circle, the columns on its surface contact the hexapod 463 once, and drive the hexapod 463 to rotate sixty degrees. The ratio of the rotation time to the stationary time of the hexapod 463 is one to five, thereby realizing the intermittent rotation of the hexapod 463. The hexapod 463 drives the six-hole turntable 43 to rotate intermittently, thereby realizing the effect of intermittent feeding of the piston piece by piece.

[0036] The intermittent rotating assembly 46 is used to drive the six-hole turntable 43 to rotate, and the pistons are transported piece by piece to the position of the conduit 2 45. The pistons fall from the conduit 2 45 onto the surface of the flip frame 475. The servo motor 2 471 drives the turntable 2 473 to rotate. The turntable 2 473 drives the quadruped 474 to rotate intermittently, flipping the piston 90 degrees so that the position of the piston corresponds to that of the cylinder.

[0037] The piston flipping process is shown in the attached Figure 6 As shown in the description, the piston falls from the conduit 45 and lies flat on the left side of the quadruped 474. The servo motor 471 drives the quadruped 474 to rotate ninety degrees clockwise, so that the piston changes from a flat state to an upright state, and flips to the right side of the quadruped 474. The cylinder 477 is used to pull the upright piston to the right, so that the piston is separated from the quadruped 474 and moved into the docking assembly mechanism 5.

[0038] Embodiment 4: According to Figure 1 , Figure 8 , Figure 9 and Figure 10 As shown, one end of the inclined plate 13 is fixedly connected to the groove seat 12, and the docking assembly mechanism 5, the groove seat 12, the two-way ejection mechanism 2 and the air supply mechanism 3 are all located on the same straight line.

[0039] The docking assembly mechanism 5 includes a hollow tube frame 51 and two movable rings 52. The inner peripheries of the two movable rings 52 are evenly spaced with inner positioning components 53. The inner positioning components 53 include a rack 531 and a pressure plate 534. Both ends of the pressure plate 534 are rotatably connected with a swing rod 533. The top of the swing rod 533 is fixedly connected with a gear 532. Specifically, the gear 532 is fixedly provided with a gear shaft, which passes through the swing rod 533. The rack 531 and the gear 532 are meshed with each other. The top surface of the inner positioning component 53 is fixedly connected with a connecting column 58. The connecting column 58 is fixedly connected to the inner side wall of the movable ring 52. The gear shafts on both sides of the gear 532 are rotatably connected with an annular frame 59. The annular frame 59 is fixedly connected to the hollow tube frame 51.

[0040] In this embodiment, in order to position the cylinder barrel and the piston on the same axis, the outer surface of the piston is accurately docked with the inner surface of the cylinder barrel. The groove of the groove seat 12 and the docking and assembling mechanism 5 are arranged on a straight line. After the cylinder barrel falls into the groove seat 12, the sliding column 22 is used to push the cylinder barrel into the docking and assembling mechanism 5.

[0041] Then, the moving ring 52 is moved outward. The moving ring 52 drives the rack 531 to move outward through the connecting column 58. Both sides of the gear 532 are limited by the annular frame 59, allowing the gear 532 to rotate on the axis defined by the annular frame 59. Utilizing the meshing relationship between the gear 532 and the rack 531, the gear 532 drives the swing rod 533 to move. The swing rod 533 then drives the pressing plate 534 to swing in the vertical direction, reducing the space enclosed by the multiple pressing plates 534, thereby achieving the effect of the pressing plates 534 tightening and clamping inward. The outer sidewall of the cylinder barrel is clamped by the multiple uniformly arranged pressing plates 534 to position it on the axis.

[0042] The piston staying at the conduit two 45 is also located between the three groups of inner positioning components 53. Move the moving ring 52 on the other side, allowing the moving ring 52 to drive the rack 531 to translate outward through the connecting column 58, so that the pressing plate 534 outside the piston clamps inward, also clamping the outer sidewall of the piston. After clamping, the piston and the cylinder barrel are on the same axis. When the cylinder barrel and the piston need to be pressed tightly, a hydraulic cylinder is set on one side. The output end of the hydraulic cylinder is used to push the cylinder barrel or the piston to translate. After the piston is inserted into the cylinder barrel, the output end of the hydraulic cylinder continuously ejects, and the cylinder barrel and the piston can be pressed tightly. After the cylinder barrel and the piston are assembled, the assembled cylinder barrel can be taken out from the docking and assembling mechanism 5 by using the hydraulic cylinder, realizing the automatic blanking after the assembly of the brake parts.

[0043] Example Five: According to Figure 1 、 Figure 8 、 Figure 9 and Figure 10 As shown, a positioning plate two 57 is fixedly connected to the bottom end of one of the moving rings 52, and a telescopic component 56 is arranged at the bottom end of the other moving ring 52. A double-output shaft cylinder 54 is arranged between the telescopic component 56 and the positioning plate two 57. A single-output shaft cylinder 55 is arranged below the double-output shaft cylinder 54. The telescopic component 56 includes a positioning plate one 561, a limit baffle 562, and a push plate 563. The top ends of the positioning plate one 561 and the limit baffle 562 are both fixedly connected to the moving ring 52. A tension spring 564 is fixedly connected between the positioning plate one 561 and the push plate 563. The two output shafts of the double-output shaft cylinder 54 are respectively fixedly connected to the positioning plate two 57 and the push plate 563. The output shaft of the single-output shaft cylinder 55 penetrates through the push plate 563 and is fixedly connected to the positioning plate one 561.

[0044] Both ends of the hollow cylinder frame 51 are fixedly installed with aluminum profile bases. The hollow cylinder frame 51 is installed on the ground through the aluminum profile bases, and a base plate is fixedly connected inside the aluminum profile bases. The double-output shaft cylinder 54 is installed on the upper surface of the base plate, and the single-output shaft cylinder 55 is installed on the side wall of the push plate 563.

[0045] In this embodiment, in order to control the movement of the moving rings 52 on both sides and adjust the inner diameter of the inner positioning components 53 on both sides to clamp inward, a double-output shaft cylinder 54 and a single-output shaft cylinder 55 are arranged below the hollow cylinder frame 51. Since the outer diameter of the cylinder barrel is larger than the outer diameter of the piston, the inner positioning component 53 clamped to the piston swings inward with a larger amplitude. The double-output shaft cylinder 54 is used to adjust the positions of the two moving rings 52 once, so that the double-output shaft cylinder 54 simultaneously pushes the positioning plate two 57 and the push plate 563 to move until the inner wall of one of the pressing plates 534 contacts the outer wall of the cylinder barrel.

[0046] The other set of pressing plates 534 has not yet contacted the outside of the piston. The single-output shaft cylinder 55 is used to control the positioning plate one 561 to move outward, so that the push plate 563 and the limit baffle 562 are separated from each other. The moving ring 52 continues to move outward, and the contact position between the pressing plate 534 and the outer side wall of the piston is controlled to complete the effect of positioning the axis of the cylinder barrel and the piston. The working frequencies of the double-output shaft cylinder 54 and the single-output shaft cylinder 55 are synchronized with the working frequency of the synchronous transmission mechanism 6, so that the feeding and docking of the cylinder barrel and the piston are synchronized, and the working efficiency of the series assembly is improved.

[0047] In the attachment Figure 17 In this equipment, it successively goes through four processes: cylinder barrel feeding, piston feeding, cylinder barrel and piston assembly, and airtightness detection of the inner cavity of the cylinder barrel. Among them, the solid arrow represents the material transportation path, the hollow double arrow represents the process of the double-directional ejection mechanism 2 pushing the cylinder barrel to move, and the hollow single arrow represents the inflation detection path.

[0048] The usage method and working principle of this device: First, transport the cylinder barrel. The cylinder barrel is transported by the conveyor belt to the inclined plate two 14 and rolls down, and is limited and stacked by the clamping block 110. The servo motor three 64 drives the bevel gear two 62 to rotate, drives the bevel gear one 61 to make the rotating shaft one 154 rotate, drives the rotating rod 153 and the strip plate 151 to move on the circular track, and the circular concave seat 152 transports the cylinder barrels forward one by one to the inclined plate one 13 and rolls down to the groove seat 12; Then transport the piston. The piston is put into the conduit one 44 and falls into the round hole of the six-hole turntable 43 by gravity. The servo motor one 461 drives the turntable one 462 to rotate, the turntable one 462 drives the six-foot frame 463 to rotate intermittently, and the six-foot frame 463 drives the six-hole turntable 43 to rotate intermittently by sixty degrees, and transports the pistons to the conduit two 45 one by one; The piston falls onto the surface of the turnover rack 475 from the conduit two 45. The servo motor two 471 drives the turntable two 473 to rotate. The turntable two 473 drives the four-legged frame 474 to rotate intermittently, turning the piston by ninety degrees to make the positions of the piston and the cylinder barrel correspond. Then, the cylinder 477 is used to move the piston into the docking and assembling mechanism 5 for docking.

[0049] Secondly, docking and assembling are carried out. In the bidirectional ejection mechanism 2, the servo motor three 64 drives the belt mechanism 63 to make the rotating shaft two 23 rotate. The rotation of the eccentric disk core 24 and the sleeve disk 25 drives the sliding column 22 to reciprocate, so that the sliding column 22 ejects the cylinder barrel into the docking and assembling mechanism 5. The moving ring 52 clamps and positions the cylinder barrel and the piston on the same axis respectively through structures such as the rack 531 and the gear 532 of the inner positioning assembly 53. The double-output shaft cylinder 54 and the single-output shaft cylinder 55 adjust the position of the moving ring 52 to adapt to the different outer diameters of the cylinder barrel and the piston. Finally, airtightness detection is completed. In the air supply mechanism 3, the sliding column 22 drives the sliding rod 31 to reciprocate, so that the air storage pipe 34 ventilates the cylinder barrel to be tested through the exhaust pipe 32. The air inlet pipe 33 replenishes filtered air into the air storage pipe 34 through the one-way valve piece 36. After sealing the cylinder barrel well, connecting the air source and the pressure detection device, then filling dry and clean compressed air or nitrogen into the cylinder barrel until the pressure reaches the specified value. After the pressurization is completed, close the air source and observe the reading change of the pressure detection device to complete the airtightness detection of the inner cavity of the cylinder barrel.

[0050] Through the above steps, the series connection of three processes of cylinder barrel feeding, cylinder barrel and piston docking, and airtightness detection of the inner cavity of the cylinder barrel is realized.
