Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a debris removal device for clutch gear hub shaft. Background Technology

[0002] An automatic transmission is a device that automatically shifts gears based on engine speed, as opposed to a manual transmission. There are four common types of automatic transmissions in automobiles: hydraulic automatic transmission (AT), continuously variable transmission (CVT), automated manual transmission (AMT), and dual-clutch transmission (DCT). In the mechanical transmission system of an automatic transmission, a clutch is typically used to achieve the disengagement or engagement of the transmission system at any time, and the gear hub shaft is an important component of the clutch.

[0003] like Figures 1-2 As shown, a clutch hub shaft A for an automatic transmission includes a disc body A-1 and a bushing A-2. One end of the bushing A-2 is fixed inside the central hole of the disc body A-1, and several radially formed channels A-3 are provided on the bushing A-2. During the machining process of this clutch hub shaft, many debris of various shapes and sizes are generated, and these debris inevitably enters the channels on the bushing. Currently, the industry typically uses manual visual inspection and debris removal. Specifically, the process involves visually inspecting the channels on the clutch hub shaft for debris, and if debris remains, using an iron bar to push it out. This manual visual inspection and debris removal method is time-consuming, labor-intensive, and prone to omissions, severely restricting the quality inspection efficiency of the clutch hub shaft, and also incurring high labor costs and poor economic benefits. Therefore, this utility model proposes a debris removal device for clutch hub shafts to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a debris cleaning device for clutch hub shafts. In use, the machined clutch hub shaft sleeve is inserted and placed inside the storage sleeve. The lifting mechanism drives the blowing cylinder to move downwards, causing the flange at the upper end of the cylinder and the worktable to work together to seal and press the sleeve from both ends in the axial direction. Then, a high-pressure air source supplies high-pressure gas to the blowing cylinder. The high-pressure gas entering the cylinder is blown out through the blowing hole and enters the sealed cavity inside the sleeve. Finally, the high-pressure gas inside the sleeve passes through the sleeve... The air is blown out of the channel and the residual debris inside the channel is also blown out, which can conveniently clean the residual debris in the channel of the bushing. Compared with the traditional manual visual inspection and debris cleaning method, it greatly reduces the amount of manual labor and significantly improves the debris cleaning efficiency of the bushing channel of the clutch gear hub shaft. This helps to greatly improve the quality inspection efficiency of the clutch gear hub shaft, reduce the quality inspection error rate, and help save labor costs. The overall structure design is ingenious and reasonable, with a small space occupation ratio, which makes it easy to connect in series in the production line of clutch gear hub shaft, resulting in good economic benefits.

The purge cylinder has a cylinder body adapted to the inner cavity of the bushing on the clutch gear hub shaft. The cylinder body is provided with several purge holes. The air inlet end of the purge cylinder is connected to a high-pressure air source. The upper end of the cylinder body has a second flange, and the outer diameter of the second flange is greater than the inner diameter of the upper port of the bushing on the clutch gear hub shaft.

[0006] This utility model discloses a debris removal device for a clutch gear hub shaft. In use, the machined clutch gear hub shaft sleeve is inserted and placed inside the storage sleeve. A lifting mechanism drives the blowing cylinder downwards, causing the flange at the upper end of the cylinder and the worktable to work together to seal and press the sleeve axially from both ends. Then, a high-pressure air source supplies high-pressure gas to the blowing cylinder. The high-pressure gas entering the cylinder is blown out through the blowing holes and into the sealed cavity inside the sleeve. Finally, the high-pressure gas inside the sleeve is blown out through the channels on the sleeve, and the channels... The residual debris inside is also blown out, making it easy to clean the debris remaining in the holes on the bushing. Compared with the traditional manual visual inspection and debris cleaning method, it greatly reduces the amount of manual labor involved, significantly improves the debris cleaning efficiency of the bushing holes of the clutch gear hub shaft, helps to greatly improve the quality inspection efficiency of the clutch gear hub shaft, reduces the quality inspection error rate, and helps to save labor costs. The overall structure design is ingenious and reasonable, with a small space occupation ratio, making it easy to connect in series in the production line of clutch gear hub shaft, resulting in good economic benefits.

[0007] The preferred technical solution is that a vertical plate and a lifting cylinder are fixedly mounted on the rear side of the upper surface of the workbench, a longitudinal guide rail is fixedly mounted on the front side of the vertical plate, a sliding seat is slidably mounted on the longitudinal guide rail, and the blowing cylinder is fixedly mounted on the sliding seat. The sliding seat is connected to the piston rod end of the lifting cylinder through a connecting plate. The vertical plate, longitudinal guide rail, sliding seat, lifting cylinder, and connecting plate constitute the lifting mechanism. The lifting mechanism has a simple structural design and high feasibility of manufacture and implementation, ensuring the smooth manufacture and implementation of the debris cleaning equipment of this utility model.

[0008] A further preferred technical solution includes a longitudinal through hole on the vertical plate, with the lifting cylinder located at the rear of the vertical plate. A connecting plate is movably inserted through the longitudinal through hole, with one end fixedly mounted on a sliding seat and the other end fixedly mounted on the piston rod end of the lifting cylinder. The sliding seat is connected to the piston rod end of the lifting cylinder via the connecting plate inserted through the longitudinal through hole. The longitudinal through hole guides the connecting plate, ensuring the stability of the purging cylinder's up-and-down movement.

[0009] A further preferred technical solution includes a "7"-shaped support plate fixedly mounted on the front side of the sliding seat, a horizontal plate fixedly mounted on the horizontal section extending forward from the "7"-shaped support plate, a vertical stepped through hole on the horizontal plate, and a rotating shaft 2 rotatably mounted inside the vertical stepped through hole via a bearing 2. A base plate is fixedly mounted at the lower end of the rotating shaft 2, and the flange 2 of the purging cylinder is fixedly mounted on the lower end face of the base plate. A gas channel penetrating the axis of the rotating shaft 2 and the center of the base plate is provided inside the rotating shaft 2. A gas inlet hose for connecting to a high-pressure gas source is connected to the upper end of the rotating shaft 2 via a rotary joint. The left and right ends of the rear side of the vertical plate are respectively fixedly connected to the rear side of the upper surface of the workbench via a reinforcing plate. The second flange of the purge cylinder is fixedly installed on the front side of the sliding seat by a horizontal plate and a "7"-shaped support plate. The installation method is simple and the structure is reasonably designed, which makes it easy to control the concentricity between the purge cylinder and the storage sleeve, that is, to ensure the stability when the purge cylinder and the worktable work together to seal and clamp the bushing of the clutch gear hub shaft from both ends into the storage sleeve.

[0010] A preferred technical solution also includes a plurality of vertical tubes fixed to the upper surface of the workbench, surrounding the outer periphery of the base. Air nozzles are installed at the upper ends of the vertical tubes, and a high-pressure air source is connected to the lower ends of the vertical tubes. When the bushing on the clutch hub shaft is inserted into the storage sleeve to clean debris, the air nozzles at the upper ends of the vertical tubes correspond to the inner peripheral wall of the disc on the clutch hub shaft. The air nozzles on the vertical tubes provide high-pressure blowing to the inner wall of the disc on the clutch hub shaft, enabling the debris cleaning device of this invention to simultaneously clean both the bushing and the disc.

[0011] A further preferred technical solution includes a plurality of vent holes on the workbench and base, each corresponding to a lower port of the riser, and a plurality of connecting pipes corresponding to the lower ports of the vent holes, the connecting pipes being connected to a high-pressure air source.

The lower end of the storage sleeve is fixedly mounted on the upper end of the top plate. Several brush assemblies surrounding the outer periphery of the base are fixedly mounted on the upper end of the workbench. Each brush assembly includes a support base and a brush head fixedly mounted on the upper end of the support base. When the bushing on the clutch gear hub shaft is inserted into the storage sleeve to clean debris, the brush heads on the several brush assemblies are in contact with the outer peripheral wall of the disc on the clutch gear hub shaft. When cleaning debris from the bushing on the clutch hub shaft, the motor can also drive the clutch hub shaft to rotate horizontally. At the same time, the brush head assembly deburrs the outer peripheral wall of the disc. This allows the debris cleaning device of this invention to perform a triple cleaning function, cleaning residual debris in the bushing channel, debris adhering to the inner wall of the disc, and burrs on the outer peripheral side of the disc. This further improves the practicality of the debris cleaning device of this invention. At the same time, when the motor drives the clutch hub shaft to rotate, the residual debris in the bushing channel can be thrown out by centrifugal force, thereby appropriately controlling the high-pressure air source within a smaller pressure range, which helps to further improve the economy of the debris cleaning device of this invention.

[0013] A further preferred technical solution includes a flexible pad fixedly embedded on the upper surface of the top plate, corresponding to the lower end of the storage sleeve; a flexible gasket fixedly embedded on the lower surface of the second flange; and a flexible bushing embedded inside the upper port of the storage sleeve. In use, the second flange at the upper end of the cylinder body and the worktable work together to seal and press the bushing from both ends in the axial direction. The flexible gasket and flexible pad protect both ends of the bushing, preventing hard pressure damage to the ends. Similarly, the flexible bushing protects the end of the bushing with the larger outer diameter, preventing pressure damage to that end and thus improving the protection of the bushing on the clutch hub shaft.

[0014] A further preferred technical solution includes a horizontal skirt folded outwards on the lower end face of the storage sleeve. A plurality of spacers are spaced circumferentially on the lower end face of the horizontal skirt. Corresponding mounting holes are provided on the spacers and the horizontal skirt. A plurality of threaded blind holes are spaced circumferentially on the outer periphery of the upper end face of the top plate. The storage sleeve and the top plate are fixedly connected together by screws passing through the mounting holes and threaded blind holes on the spacers and the horizontal skirt. The method of fixing the lower end of the storage sleeve to the top plate is simple, and the gaps between the spacers allow blown-down debris to be discharged to the outside of the storage sleeve, further ensuring the cleaning efficiency of the bushing on the clutch hub shaft.

[0015] A further preferred technical solution is that the lower end face of the workbench has several legs, the upper end of the motor has a flange, and the motor is fixedly mounted on the lower end face of the workbench by screws passing through the mounting holes on the flange.

[0047] The working principle of the debris cleaning device for clutch gear hub shaft of this utility model is as follows:

[0048] Step 1: In the initial state, the sliding seat 12 is located at the upper end of the longitudinal guide rail 11, that is, the purging cylinder 16 and the storage sleeve 4 are separated. The cleaning time of the single clutch gear hub shaft A is set by the control system.

[0049] Step 2: Insert the machined clutch hub shaft A's bushing A-2 into the storage sleeve 4. At this time, the disc body A-1 is located at the upper end of the storage sleeve 4. Several air nozzles 7-1 on the riser 7 are distributed around the outer periphery of the disc body A-1. Some air nozzles 7-1 correspond to the inner peripheral wall of the disc body A-1, and other air nozzles 7-1 correspond to the inner top wall of the disc body A-1 (see Appendix). Figure 9 and attached Figure 10 );

[0050] Step 3: By pressing the start button on the control system, the piston rod 19-1 of the lifting cylinder 19 extends and drives the sliding seat 12 downward until the flange 16-1 on the purging cylinder 16 presses the lower end of the bushing A-2 against the flexible pad 3-2 through the flexible washer 16-3. The piston rod 19-1 of the lifting cylinder 19 stops, thereby pressing and sealing the upper and lower ends of the bushing A-2 through the flexible washer 16-3 and the flexible pad 3-2. Then, the high-pressure air source supplies high-pressure purging gas to several risers 7 and the purging cylinder 16. At the same time, the output shaft 6-1 of the motor 6 rotates and drives the clutch hub shaft A to start rotating. The high-pressure gas blown out through the purging hole 16-2a on the cylinder body 16-2 enters the interior of the bushing A-2. The high-pressure gas inside the bushing A-2 is blown out through the channel A-3, and at the same time, the gas inside the channel A-3 is blown out. The remaining debris is blown out and blown to the outside of the storage sleeve 4 through the gap between the bottom pad 4-1 of the storage sleeve 4. The high-pressure gas entering the riser 7 is blown out through the air nozzle 7-1 and cleans the debris on the inner wall of the disc A-1. As the output shaft 6-1 of the motor 6 rotates and drives the clutch hub shaft A to rotate, the brush head 9-2 on the brush assembly 9 deburrs the outer peripheral wall of the disc A-1. When the set cleaning time is reached, the high-pressure air source stops supplying air and the motor 6 stops rotating. After the motor 6 stops rotating completely, the piston rod 19-1 of the lifting cylinder 19 begins to retract and reset, causing the sliding seat 12 to slide to the upper end of the longitudinal guide rail 11. At this time, the blowing cylinder 16 and the storage sleeve 4 return to the separated state, and the cleaned clutch hub shaft A is removed, completing one debris cleaning cycle of the clutch hub shaft A.

[0051] This utility model discloses a debris removal device for a clutch gear hub shaft. In use, the machined clutch gear hub shaft sleeve is inserted and placed inside the storage sleeve. A lifting mechanism drives the blowing cylinder downwards, causing the flange at the upper end of the cylinder and the worktable to work together to seal and press the sleeve axially from both ends. Then, a high-pressure air source supplies high-pressure gas to the blowing cylinder. The high-pressure gas entering the cylinder is blown out through the blowing holes and into the sealed cavity inside the sleeve. Finally, the high-pressure gas inside the sleeve is blown out through the channels on the sleeve, and the channels... The residual debris inside is also blown out, making it easy to clean the debris remaining in the holes on the bushing. Compared with the traditional manual visual inspection and debris cleaning method, it greatly reduces the amount of manual labor involved, significantly improves the debris cleaning efficiency of the bushing holes of the clutch gear hub shaft, helps to greatly improve the quality inspection efficiency of the clutch gear hub shaft, reduces the quality inspection error rate, and helps to save labor costs. The overall structure design is ingenious and reasonable, with a small space occupation ratio, making it easy to connect in series in the production line of clutch gear hub shaft, resulting in good economic benefits.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
