Description

Technical Field

[0001] The present invention relates to the technical field of brake assembly, in particular to a multi-process serial brake cylinder and piston assembly device. Background Art

[0002] Brakes are divided into disc brakes and drum brakes. Both disc brakes and drum brakes have parts such as cylinders and pistons inside. The brake fluid pushes the piston to move, causing the brake pads to cooperate with the wheels, thereby producing a braking effect.

[0003] In existing technology, cylinder and piston parts require separate loading during assembly. This means each loading step requires a separate operation, which is not only time-consuming but also prone to human error due to the increased number of steps. Furthermore, the lack of effective integration and connection between various links results in a lengthy production process and inefficient equipment operation. This separate loading method is unable to meet the growing market demand and the company's pursuit of efficient production, significantly limiting the production scale and delivery speed of related products.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the three key processes of cylinder loading, cylinder and piston docking, and cylinder inner cavity air tightness detection are connected in series. The cylinder loading mechanism realizes automatic, piece-by-piece loading of the cylinder through the coordinated operation of the conveyor belt, inclined plate, clamping block and transportation component, and utilizes servo motor three to drive rotating shaft one and rotating shaft two respectively.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0043] Example 1: According to Figure 1 - Figure 17 As shown, a multi-process tandem brake cylinder and piston assembly device includes a cylinder feeding mechanism 1, an air supply mechanism 3, and a piston feeding mechanism 4. The cylinder feeding mechanism 1 is used to feed cylinders one by one, while the piston feeding mechanism 4 is used to feed pistons one by one. A docking assembly mechanism 5 is provided between the two. The air supply mechanism 3 is provided on the other side of the cylinder feeding mechanism 1 to ventilate the cylinder cavity. The docking assembly mechanism 5 is used for one-to-one assembly of the cylinder and piston. A bidirectional ejection mechanism 2 is provided on the outside of the cylinder feeding mechanism 1.

[0044] The bidirectional ejection mechanism 2 comprises a U-shaped base 21, rotatably connected to a second rotating shaft 23 at its center. The top of the second rotating shaft 23 is fixedly connected to an eccentric disc core 24. A sleeve disc 25 rotatably fits around the outer wall of the eccentric disc core 24, and a disc housing 26 rotatably connected to the outer wall of the sleeve disc 25. Sliding posts 22 are slidably connected to each end of the U-shaped base 21, one end of each of the sliding posts 22 being fixedly connected to the disc housing 26. One of the sliding posts 22 pushes the cylinder barrel and piston together, while the other pushes the sealing plug 35 within the air supply mechanism 3 to initiate inflation.

[0045] The cylinder loading 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 provided 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.

[0046] A synchronous transmission mechanism 6 is arranged between the transport component 15 and the rotating shaft 2 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 engaged 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 connected by a belt mechanism 63.

[0047] The processes involved in brake assembly include: cylinder loading, piston loading, cylinder and piston docking, cylinder and piston compression, and cylinder inner cavity airtightness testing. This equipment is used for brake assembly with a straight cylinder. Installed on the ground, it connects the three processes of cylinder loading, cylinder and piston docking, and cylinder inner cavity airtightness testing in series to ensure process order and consistency.

[0048] The principle of loading the cylinder is as follows: after the cylinder is manufactured, a batch of cylinders are transported to the inclined plate 2 14 by the conveyor belt. After the cylinder reaches the inclined plate 2 14, it rolls down along the inclined surface and is limited by the block 110 at one end. Multiple cylinders are piled up on the upper surface of the inclined plate 2 14. The servo motor 3 64 drives the bevel gear 2 62 to rotate, and the bevel gear 2 62 drives the bevel gear 1 61 to rotate. The bevel gear 1 61 drives the rotating shaft 154 to rotate continuously. The rotating shaft 154 drives the rotating rod 153 to rotate. The rotating rod 153 drives the strip 151 to move within the circular running track. The other end of the strip 151 is driven by another A rotating rod 153 is limited so that the strip 151 always remains parallel to the ground when moving. The strip 151 moves to the upper half of the circular track, and the circular recess 152 contacts the cylinders stacked on one side of the base 11 and transports the cylinders forward one by one. The strip 151 moves to the lower half of the circular track, and the circular recess 152 separates from the transported cylinders. Each time the circular recess 152 contacts the cylinder, it can move the cylinder forward one position until the cylinder is moved to the position of the inclined plate 13. The cylinder rolls downward along the inclined surface of the inclined plate 13 and finally stops at the groove seat 12, completing the process of loading the cylinders one by one.

[0049] The principle of docking of the cylinder and the piston is as follows: the cylinder and the piston are located on both sides of the docking assembly mechanism 5, and the cylinder and the piston need to be positioned to ensure that they are located on the same axis. The function of the two-way ejection mechanism 2 is to push the outer cylinder into the interior of the docking assembly mechanism 5 so that the internal structure of the docking assembly mechanism 5 positions it. The output end of the servo motor 3 64 drives the belt mechanism 63 to operate, so that the belt mechanism 63 drives the rotating shaft 2 23 to rotate continuously. The top end of the rotating shaft 23 is installed at a position deviated from the center of the eccentric disk core 24. The distance between the rotating shaft 23 and the center of the eccentric disk core 24 is a constant value, and the distance between the center of the eccentric disk core 24 and the center of the disk shell 26 is also a constant value. The two distances can be regarded as a connecting rod structure. When the rotating shaft 23 drives the eccentric disk core 24 to rotate, the angle of the connecting rod changes continuously. When the angle of the connecting rod is zero degrees, the rotating shaft 23 is closest to the center of the sleeve disk 25; when the angle of the connecting rod is one hundred and eighty degrees, the rotating shaft 23 is farthest from the center of the sleeve disk 25. Each time the second rotating shaft 23 rotates one circle, the angle of the connecting rod is twice at 180 degrees. At this time, the disc housing 26 moves to the outermost sides of the U-shaped seat 21 and is pushed outward by the sliding posts 22 at both ends. Then, one of the sliding posts 22 pushes the cylinder into the docking assembly mechanism 5 to complete the assembly and docking.

[0050] The principle of the air tightness test of the cylinder cavity is: when the servo motor 3 64 drives the two-way ejection mechanism 2 to push left and right, the sliding column 22 at the other end pushes the sliding rod 31 to move back and forth, and the air supply mechanism 3 continuously replenishes air into the conduit. When the cylinder and the piston are assembled, it is used to test the air tightness of the cylinder cavity.

[0051] Example 2: According to Figure 1 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14 As shown, the air supply mechanism 3 includes a sliding rod 31, an exhaust pipe 32, an intake pipe 33, and an air storage pipe 34. The sliding rod 31 is slidably connected to the air storage pipe 34. A sealing plug 35 is fixedly connected to one end of the sliding rod 31. The sealing plug 35 is slidably connected to the inner side wall of the air storage pipe 34. The sliding rod 31 is fixedly connected to one of the sliding columns 22. Two openings are provided on one side of the exhaust pipe 32 and the intake pipe 33. The exhaust pipe 32 and the intake pipe 33 are respectively located on either side of the air storage pipe 34. Both openings of the exhaust pipe 32 and the intake pipe 33 are connected to the air storage pipe 34, and a one-way valve 36 is provided at each opening. One end of the exhaust pipe 32 is connected to a conduit, through which the exhaust pipe 32 vents into the cylinder to be tested. A filter is fixedly connected to one end of the intake pipe 33.

[0052] In this embodiment, refer to the attached Figure 12 As shown in the figure, when the sliding rod 31 is pushed to the left, the cavity space on the left side shrinks, the air pressure increases, and the one-way valve disc 36 on the upper left side opens, and gas is discharged from the gas storage pipe 34 to the exhaust pipe 32; the cavity space on the right side expands, the air pressure decreases, and the one-way valve disc 36 on the lower right side opens, and gas is replenished from the air intake pipe 33 to the gas storage pipe 34. When the sliding rod 31 is retracted to the right, the cavity space on the left side expands, the air pressure decreases, and the one-way valve disc 36 on the lower left side opens, and gas is replenished from the air intake pipe 33 to the gas storage pipe 34; the cavity space on the right side shrinks, the air pressure increases, and the one-way valve disc 36 on the upper right side opens, and gas is discharged from the gas storage pipe 34 to the exhaust pipe 32.

[0053] As the sliding column 22 drives the sliding rod 31 back and forth, the air intake pipe 33 continuously replenishes air to the air storage pipe 34, which then continuously discharges air to the exhaust pipe 32. A conduit then collects the air in the exhaust pipe 32 and fills the tank. The tank's air pipe connects to the spray gun, which emits high-pressure gas through the oil inlet of the cylinder and into the inner cavity of the cylinder. Before entering the air storage pipe 34, the air is filtered by a filter on the air intake pipe 33 to prevent clogging of the air supply mechanism 3 and the cylinder.

[0054] Example 3: According to Figure 1 、 Figure 4 、 Figure 5 and Figure 6As shown, the piston feeding mechanism 4 includes a circular plate 1 41, a circular plate 2 42 and a six-hole turntable 43. The outer sides of the circular plate 1 41 and the circular plate 2 42 are fixedly connected with a bracket. The circular plate 1 41 and the circular plate 2 42 are installed on the ground through the bracket. The six-hole turntable 43 is located between the circular plate 1 41 and the circular plate 2 42. The six-hole turntable 43 is rotatably connected to the circular plate 1 41 and the circular plate 2 42. Through holes are provided on the surfaces of the circular plate 1 41 and the circular plate 2 42. The top surface of the circular plate 1 41 is located at the through hole and is fixedly connected to the conduit 1 44. The bottom surface of the circular plate 2 42 is located at the through hole and is fixedly connected to the conduit 2 45. The bottom end of the conduit 2 45 is located on the same axis as the docking assembly mechanism 5.

[0055] An intermittent rotation component 46 is provided below the bottom end of the circular plate 2 42. The intermittent rotation component 46 includes a gantry 464. A hexapod 463 is rotatably connected to the center position of the gantry 464. The top of the hexapod 463 passes through the circular plate 2 42 and is fixedly connected to the bottom surface of the six-hole turntable 43. A servo motor 461 is installed at the bottom end of the gantry 464. The output end of the servo motor 461 is fixedly connected to the turntable 462. The turntable 462 drives the hexapod 463 to rotate intermittently.

[0056] A flip assembly 47 is provided below the bottom end of the catheter 2 45, and the flip assembly 47 includes a gantry 2 472. A servo motor 2 471 is installed on the outer wall of the gantry 2 472. The output end of the servo motor 471 is fixedly connected to a turntable 2 473. The side wall of the gantry 2 472 is rotatably connected to a quadruped 474. The turntable 2 473 is used to drive the quadruped 474 to rotate intermittently. One end of the quadruped 474 is fixedly connected to a flip frame 475. The docking assembly mechanism 5 is installed with a cylinder 477. The output end of the cylinder 477 is fixedly connected to a push-pull plate 476. The push-pull plate 476 is used to move the piston on the flip frame 475 into the docking assembly mechanism 5.

[0057] In this embodiment, the outer shape of the cylinder is a cylinder, and the outer shape of the piston is a disc structure. Due to the influence of the respective structures of the cylinder and the piston, the cylinder can load materials in a rolling state. When transporting the piston, it is put into the conduit 44, and slides down in the conduit 44 due to the action of gravity, and falls from the opening of the circular plate 41 into a circular hole of the six-hole turntable 43.

[0058] 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 set under the circular plate 2, and a servo motor 461 is installed under the gantry 464. The servo motor 461 directly drives the turntable 462 to rotate. Every time the turntable 462 rotates one circle, the column on its surface contacts the hexapod 463 once, and drives 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 loading of the pistons one by one.

[0059] The intermittent rotation component 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 second conduit 45. The pistons fall from the second conduit 45 onto the surface of the flip frame 475. The servo motor 471 drives the second turntable 473 to rotate. The second turntable 473 drives the quadruped 474 to rotate intermittently, flipping the piston ninety degrees so that the position of the piston corresponds to that of the cylinder.

[0060] The piston flipping process is shown in the attached Figure 6 As shown in the figure, the piston falls from the second conduit 45 and lies flat on the left side of the quadruped 474. The second 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.

[0061] Example 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.

[0062] The docking assembly mechanism 5 includes a hollow tube frame 51 and two movable rings 52. The inner periphery of the two movable rings 52 is evenly spaced with internal positioning components 53. The internal positioning component 53 includes a rack 531 and a pressure plate 534. Both ends of the pressure plate 534 are rotatably connected to a swing rod 533. The top of the swing rod 533 is fixedly connected to 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 engaged with each other. The top surface of the internal positioning component 53 is fixedly connected to 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 to an annular frame 59. The annular frame 59 is fixedly connected to the hollow tube frame 51.

[0063] In this embodiment, in order to position the cylinder and the piston on the same axis and to precisely mate the outer surface of the piston with the inner surface of the cylinder, the groove of the groove seat 12 and the docking assembly mechanism 5 are set on a straight line. After the cylinder falls into the groove seat 12, the sliding column 22 is used to push the cylinder into the docking assembly mechanism 5.

[0064] Then, the movable ring 52 is moved outward, and the movable ring 52 drives the rack 531 to move outward through the connecting column 58. The two 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. The meshing relationship between the gear 532 and the rack 531 is utilized to make the gear 532 move with the swing rod 533, and the swing rod 533 drives the pressure plate 534 to swing in the vertical direction, so that the space enclosed by the multiple groups of pressure plates 534 becomes smaller, thereby achieving the effect of tightening and clamping the pressure plate 534 inward, and utilizing multiple groups of evenly arranged pressure plates 534 to clamp the outer wall of the cylinder barrel to position it on the axis.

[0065] The piston stopped at the second conduit 45 is also located between the three groups of inner positioning components 53. Move the movable ring 52 on the other side, and let the movable ring 52 drive the rack 531 to translate outward through the connecting column 58, so that the pressure plate 534 on the outside of the piston is clamped inward, so that it also clamps the outer wall of the piston. After clamping, the piston and cylinder are located on the same axis. When the cylinder and piston need to be compressed, a hydraulic cylinder is set on one side, so that the output end of the hydraulic cylinder pushes the cylinder or piston to translate. After the piston is inserted into the cylinder, the output end of the hydraulic cylinder continues to push out, and the cylinder and piston can be compressed. After the cylinder and piston are assembled, the assembled cylinder can be removed from the docking assembly mechanism 5 using the hydraulic cylinder, and automatic unloading of the brake parts can be realized after assembly.

[0066] Example 5: According to Figure 1 、 Figure 8 、 Figure 9 and Figure 10 As shown, the bottom end of one of the moving rings 52 is fixedly connected to the positioning plate 2 57, and the bottom end of the other moving ring 52 is provided with a telescopic component 56, a double-output shaft cylinder 54 is provided between the telescopic component 56 and the positioning plate 2 57, and a single-output shaft cylinder 55 is provided below the double-output shaft cylinder 54, the telescopic component 56 includes a positioning plate 1 561, a limit baffle 562 and a push plate 563, the top ends of the positioning plate 1 561 and the limit baffle 562 are fixedly connected to the moving ring 52, and a tension spring 564 is fixedly connected between the positioning plate 1 561 and the push plate 563, the two output shafts of the double-output shaft cylinder 54 are fixedly connected to the positioning plate 2 57 and the push plate 563 respectively, and the output shaft of the single-output shaft cylinder 55 passes through the push plate 563 and is fixedly connected to the positioning plate 1 561.

[0067] An aluminum profile base is fixedly installed at both ends of the hollow tube frame 51. The hollow tube frame 51 is installed on the ground through the aluminum profile base, and a base plate is fixedly connected inside the aluminum profile base. The double-axis cylinder 54 is installed on the upper surface of the base plate, and the single-axis cylinder 55 is installed on the side wall of the push plate 563.

[0068] In this embodiment, in order to control the movement of the movable rings 52 on both sides and adjust the inner diameter of the inner positioning components 53 on both sides that are clamped inward, a double-outlet shaft cylinder 54 and a single-outlet shaft cylinder 55 are set below the hollow cylinder frame 51. Since the outer diameter of the cylinder is larger than the outer diameter of the piston, the inner positioning component 53 clamped by the piston has a larger inward swing amplitude, and the double-outlet shaft cylinder 54 is used to adjust the position of the two movable rings 52 once, so that the double-outlet shaft cylinder 54 simultaneously pushes the positioning plate 2 57 and the push plate 563 to move until the inner wall of one of the pressure plates 534 contacts the outer wall of the cylinder.

[0069] The other set of pressure plates 534 has not yet contacted the outer side of the piston. The single-shaft cylinder 55 controls the outward movement of positioning plate 1 561, separating the push plate 563 and the stopper 562. The movable ring 52 continues to move outward, controlling the contact position of the pressure plates 534 with the outer wall of the piston, thus completing the positioning of the cylinder and piston axes. The operating frequencies of the dual-shaft cylinders 54 and the single-shaft cylinder 55 are synchronized with the operating frequency of the synchronous transmission mechanism 6, ensuring that the loading and docking of the cylinder and piston are synchronized, improving the efficiency of the series assembly.

[0070] In the attached Figure 17 In the figure, the equipment goes through four processes in sequence: cylinder loading, piston loading, cylinder and piston assembly, and cylinder inner cavity air tightness detection. Among them, the solid arrow represents the material transportation path, the hollow double arrow represents the process of the two-way ejection mechanism 2 pushing the cylinder to move, and the hollow single arrow represents the inflation detection path.

[0071] The device's operating method and working principle are as follows: First, the cylinders are transported by a conveyor belt to the second inclined plate 14, where they roll down and are limited by the clamping block 110. The servo motor 3 64 drives the second bevel gear 62 to rotate, which in turn drives the first bevel gear 61 to rotate the first rotating shaft 154, driving the rotating rod 153 and the strip 151 to move along a circular trajectory. The circular recess 152 transports the cylinders forward one by one to the first inclined plate 13, where they roll down to the groove seat 12.

[0072] The pistons are then transported and placed into conduit 1 (44), where they fall under gravity into the circular holes of six-hole turntable 43. Servo motor 1 (461) drives turntable 1 (462), which in turn drives hexapod 463 to rotate intermittently, which in turn drives six-hole turntable 43 to rotate intermittently 60 degrees, moving the pistons one by one into conduit 2 (45).

[0073] The piston falls from the second conduit 45 onto the surface of the turning frame 475, and the second servo motor 471 drives the second turntable 473 to rotate, and the second turntable 473 drives the quadruped 474 to rotate intermittently, turning the piston ninety degrees so that the position of the piston and the cylinder barrel correspond. The piston is moved into the docking assembly mechanism 5 for docking using the cylinder 477.

[0074] Next, docking and assembly proceed. In the bidirectional ejection mechanism 2, servo motor 3 64 drives belt mechanism 63 to rotate rotating shaft 23. The rotation of eccentric disc core 24 and sleeve disc 25 drives sliding column 22 to reciprocate, causing sliding column 22 to push the cylinder into the docking assembly mechanism 5. The movable ring 52, through the rack 531 and gear 532 of the internal positioning assembly 53, clamps the cylinder and piston together and positions them on the same axis. The dual-axis cylinder 54 and single-axis cylinder 55 adjust the position of the movable ring 52 to accommodate the different outer diameters of the cylinder and piston.

[0075] Finally, the air tightness test is completed. In the air supply mechanism 3, the sliding column 22 drives the sliding rod 31 to move back and forth, so that the air storage pipe 34 ventilates the cylinder to be tested through the exhaust pipe 32, and the air intake pipe 33 replenishes the filtered air to the air storage pipe 34 through the one-way valve plate 36. The cylinder is sealed, the air source and the pressure detection device are connected, and then dry, clean compressed air or nitrogen is filled into the cylinder to make the pressure reach the specified value. After the pressurization is completed, the air source is turned off, and the reading changes of the pressure detection device are observed to complete the air tightness test of the cylinder cavity.

[0076] Through the above steps, the three processes of cylinder loading, cylinder and piston docking, and cylinder inner cavity air tightness detection are connected in series.
