Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of punching equipment, and particularly relates to a punching equipment for an automotive clutch driven plate assembly. Background Art
[0002] As a core component in the power transmission system, the structural accuracy of the automotive clutch driven plate assembly directly affects the smooth engagement and transmission reliability of the clutch. The driven plate body is usually composed of a hub assembly with friction linings, and a number of mounting and positioning holes need to be evenly processed circumferentially on the plate body to achieve precise assembly with the flywheel. A hole position deviation exceeding 0.1 mm may cause dynamic balance failure. Traditional hydraulic punching equipment adopts a single-side stamping mode, and only completes the blanking operation by applying force unidirectionally through the lower die, without a dynamic compensation mechanism on the upper side. This asymmetric stamping method causes a slight offset of the plate body under the action of unbalanced radial forces when the punch contacts the plate body, because there is no synchronous reaction force support on the punching side, especially when punching a thin-walled high-carbon steel driven plate. This deformation directly causes a deviation in the diameter of the circumferential hole distribution circle, which not only reduces the assembly accuracy, but also causes harmonic resonance during high-speed rotation, resulting in abnormal wear of the clutch assembly. Summary of the Invention
[0003] In view of the above technical problems, the present invention discloses a punching equipment for an automotive clutch driven plate assembly, including an equipment base. A lower mounting plate is installed on the equipment base, and a sleeve is fixedly installed on the lower mounting plate. A first sliding rod and a second sliding rod are respectively slidably installed at the upper and lower ends of the sleeve. A drilling assembly is installed on the first sliding rod, and a positioning sleeve is installed on the second sliding rod. The positioning sleeve is a hollow structure and is located corresponding to the drilling assembly. Through the above technical solution, the drilling assembly and the positioning sleeve are respectively located at the upper and lower ends of the driven plate. When the drilling assembly drills downward, the positioning sleeve supports it, making it not easy for the driven plate to shift and ensuring the accuracy of drilling.
[0004] Further, a driven gear is rotatably installed in the sleeve. First and second lead screws are fixedly installed at both ends of the driven gear. Threaded holes are provided in the second sliding rod and the first sliding rod. The first sliding rod cooperates with the first lead screw, and the second lead screw cooperates with the second sliding rod.
[0005] Further, a clamping assembly is installed on the equipment base. The clamping assembly clamps the driven plate, and the positioning sleeve and the drill bit are located on the upper and lower sides of the driven plate.
[0006] Furthermore, a track rod is fixedly mounted on the base of the device, a lower mounting plate is slidably mounted on the track rod, an extension tube is fixedly mounted on the base of the device, a height spring is fixedly mounted on the extension tube, and the height spring is fixedly connected to the lower mounting plate. Through the above technical solution, the driven gear rotates to drive the first lead screw and the second lead screw, thereby simultaneously driving the drilling assembly and the positioning sleeve to move. When the positioning sleeve contacts the driven disk, the positioning sleeve cannot continue to rise, so the lower mounting plate will drop to compress the height spring, thereby ensuring the complete operation of the machine.
[0007] Furthermore, the second sliding rod is fixedly provided with a second connecting plate, the first sliding rod is fixedly provided with a first connecting plate, the second connecting plate is rotatably provided with a driving disk, the driving disk is provided with a nozzle, the positioning sleeve is a round tube with openings at both ends, and the nozzle is used to clean the inner wall of the positioning sleeve.
[0008] Furthermore, a support rod is fixedly mounted on the driving disk, a rotating pin is rotatably mounted on the support rod, a matching rod is fixedly mounted on the rotating pin, a water spray rod is fixedly mounted on the matching rod, two water spray heads are arranged at the end of the water spray rod, a torsion spring is fixedly mounted between the rotating pin and the support rod, and an angle is arranged between the water spray rod and the matching rod.
[0009] Furthermore, a liquid collecting tank is fixedly installed on the base of the equipment, and a hydraulic pump is fixedly installed in the liquid collecting tank. The hydraulic pump is connected to the matching rod to supply water to the water spraying rod. A connecting pipe is arranged at the lower part of the matching rod, and the connecting pipe is inserted into the supporting rod to start supplying water.
[0010] Furthermore, a water spray head 1 is fixedly mounted on the water spray rod, and the water spray direction of the water spray head 1 is perpendicular to that of the water spray head 2. Through the above technical solution, when the water spray head 1 and the water spray head 2 enter the positioning sleeve, they clean the inner wall of the positioning sleeve, so that the chips will not stick to the positioning sleeve. The chips sticking to the positioning sleeve will affect the accuracy of drilling. At the same time, cleaning heads with multiple angles are set, and the chips at different positions can be cleaned, which can clean both the inner wall and the top. When the positioning sleeve descends, the matching rod is moved, and the connecting pipe is inserted into the support rod to pass water. At this time, the water spray rod rotates to the specified angle for cleaning.
[0011] Furthermore, the clamping assembly includes a support frame, a lower horizontal frame is fixedly mounted on the support frame, a positioning motor is fixedly mounted on the lower horizontal frame, a mounting seat is fixedly mounted on the rotating shaft of the positioning motor, a clamping shaft is fixedly mounted on the mounting seat, a clamping head is detachably mounted on the clamping shaft, and the mounting seat is squeezed downward by a clamping electric cylinder.
[0012] The beneficial effects of the present invention compared with the prior art are: (1) Through the technical solution of the present invention, the drilling assembly and the positioning sleeve are respectively located at the upper and lower ends of the driven disc. When the drilling assembly drills downward, the positioning sleeve supports it, making it not easy for the driven disc to shift and ensuring the accuracy of drilling.
[0013] (2) Through the technical solution of the present invention, the driven gear rotates to drive the first lead screw and the second lead screw, and then simultaneously drives the drilling assembly and the positioning sleeve to move. When contacting the driven disc, the positioning sleeve cannot continue to rise, so the lower mounting plate will descend to compress the height spring, ensuring the complete operation of the machine.
[0014] (3) Through the technical solution of the present invention, when the water spray head 1 and the water spray head 2 enter the positioning sleeve, they clean the inner wall of the positioning sleeve, preventing chips from sticking to the positioning sleeve. Chips sticking to the positioning sleeve will affect the drilling accuracy. At the same time, cleaning heads at multiple angles are provided to clean chips at different positions, being able to clean both the inner wall and the upper part. When the positioning sleeve descends, it toggles the cooperating rod and simultaneously drives the connecting pipe to insert into the support rod to conduct water. At this time, the water spray rod rotates to a specified angle for cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

Through the above technical solution, rotation of the driven gear 12 drives the first lead screw 13 and the second lead screw 15, and further drives the drilling assembly and the positioning sleeve 24 to move simultaneously. When contacting the driven disk 47, the positioning sleeve 24 cannot continue to rise, so the lower mounting plate 7 will descend to compress the height spring 6, ensuring the complete operation of the machine.

[0031] A water spray head 1 45 is fixedly mounted on the water spray rod 44, and the water spray direction of the water spray head 1 45 is perpendicular to that of the water spray head 2 46. Through the above technical solution, when the water spray head 1 45 and the water spray head 2 46 enter the positioning sleeve 24, the inner wall of the positioning sleeve 24 is cleaned, so that the chips will not stick to the positioning sleeve 24, and the chips sticking to the positioning sleeve 24 will affect the accuracy of the drilling. At the same time, multiple cleaning heads are set at different angles, and the chips at different positions can be cleaned, which can clean both the inner wall and the upper surface. When the positioning sleeve 24 descends, the matching rod 41 is moved, and the connecting pipe 48 is driven to be inserted into the support rod 39 to pass water.

[0032] In this embodiment, the clamping assembly includes a support frame 26, a mobile electric cylinder 25 is fixedly mounted on the equipment base 1, a support frame 26 is fixedly mounted on the output end of the mobile electric cylinder 25, a lower horizontal frame 27 and an upper horizontal frame 29 are fixedly mounted on the support frame 26, a positioning motor 28 is fixedly mounted on the lower horizontal frame 27, a mounting seat 30 is fixedly mounted on the rotating shaft of the positioning motor 28, a clamping shaft 35 is fixedly mounted on the mounting seat 30, a clamping head 36 is detachably mounted on the clamping shaft 35, a connecting piece 32 is fixedly mounted on the clamping sleeve 33, and the connecting piece 32 A cylinder arm with a clamping electric cylinder 31 is fixed on the upper part, and the clamping electric cylinder 31 is fixedly installed on the mounting seat 30. After the clamping head 36 is removed, the driven disk 47 is placed on it, and then the driven disk 47 is installed concentrically with the clamping shaft 35. The clamping head 36 is installed to be squeezed and fixed. At the same time, the driven disk 47 is driven to rotate by the positioning motor 28. A clamping gasket 34 is fixedly installed on the clamping sleeve 33. The upper side of the clamping gasket 34 is in contact with the lower side of the driven disk 47, driving the driven disk 47 to rotate, and squeezing the mounting seat 30 downward through the clamping electric cylinder 31.
[0033] In this embodiment, the drilling assembly includes a connecting disk 21, which is rotatably mounted on the first connecting plate 18. A transmission rod 20 is slidably mounted on the connecting disk 21. A drill bit 23 is mounted at the bottom of the transmission rod 20.

A power source such as an electric motor or a hydraulic motor is installed on the first connecting plate 18 to drive the transmission rod 20 to rotate.
[0034] Working principle: First, remove the clamping head 36. The clamping head 36 and the clamping shaft 35 are connected by bolts, which is convenient for disassembly. Then, place the driven disk 47 on the clamping gasket 34, and then install the clamping head 36 and tighten the bolts. At this time, the clamping head 36 has not yet pressed the driven disk 47. Subsequently, start the clamping electric cylinder 31. The clamping electric cylinder 31 drives the clamping sleeve 33 to rise, and the mounting seat 30 descends. The mounting seat 30 drives the clamping shaft 35 and the clamping head 36 to descend, and the clamping sleeve 33 and the clamping gasket 34 rise to clamp the driven disk 47 in the middle.
[0035] Start the telescopic motor 10. The telescopic motor 10 drives the driving gear 11 to rotate.

The top of the positioning sleeve 24 and the bottom of the drill bit 23 contact the driven disk 47. The transmission rod 20 rotates to drive the drill bit 23 to start drilling, and liquid is sprayed for cooling. Finally, the drill bit 23 penetrates the driven disk 47 and enters the positioning sleeve 24. During the process, the positioning sleeve 24 cannot continue to rise after contacting the driven disk 47. At this time, the lower mounting plate 7 and the upper mounting plate 8 will descend as a whole to squeeze the height spring 6.
[0036] After drilling, return to the original position.

The liquid collecting tank 37 and the baffle 3 collect the cooling wastewater, filter it through the hydraulic pump 38 and then send it to the mating rod 41. The mating rod 41 stands up to make the second sprinkler head 46 clean the inner wall of the positioning sleeve 24 obliquely upward. Finally, the first sprinkler head 45 extends to the positioning sleeve 24, and the first sprinkler head 45 cleans the chips on the upper end face of the positioning sleeve 24.
