Description

Technical Field

[0001] This invention relates to the technical field of cleaning the outer cylinder of shock absorbers, and in particular to a mechanism for cleaning the inner wall of the outer cylinder of shock absorbers. Background Technology

[0002] The outer cylinder of the shock absorber is the core hydraulic buffer component in the automotive shock absorption system, mainly responsible for sealing, support and energy absorption functions. During the processing of the outer cylinder, it usually needs to be stamped and welded, which results in oil stains, debris and welding slag adhering to the inner wall of the outer cylinder. A cleaning machine is required to clean the inner wall of the outer cylinder. The prior art patent number CN223405532U discloses an ultrasonic cleaning tank for a shock absorber sleeve. The set support grid can support the cleaning columns arranged in a circumferential interval, so that the cleaning columns will continuously rotate around the axis and spray liquid under the rotation drive of the rotation drive mechanism and the cleaning liquid supply of the flushing liquid supply mechanism, thereby achieving efficient cleaning of the inner cavity of the workpiece and removal of impurities, thereby improving the overall cleaning effect and quality. However, in actual cleaning, since the cleaned workpieces are taken directly from the storage tank, a large amount of cleaning fluid remains on the workpieces. This not only wastes the cleaning fluid, but also causes the residual cleaning fluid to drip directly from the workpieces when they are taken out, reducing the quality of the working environment.

The gripping structure includes: fixed plates 17 fastened to the front of two movable seats 16 respectively; two fixed cylinders 19 are installed under each fixed plate 17; multiple grooves 20 are formed at equal angles on the bottom side of the fixed cylinder 19; a rotating shaft is rotatably connected between the two end walls of each groove 20; a flip handle 22 is fixedly sleeved on each rotating shaft; a clamping block 51 is set at one end of the flip handle 22; a cylinder 18 is installed on the fixed plate 17 above each fixed cylinder 19; the output shaft of the cylinder 18 is connected to a driving column 23 that is movably inserted into the fixed cylinder 19; a driving bar 24 is set on the side of the driving column 23; a fourth gear 21 is fixedly sleeved in the middle of the rotating shaft; teeth are provided on the driving bar 24 that mesh with the fourth gear 21.

The entire assembly moves downwards, with the two sets of clamping blocks 51 moving down into the cleaning chamber 6 and the wiping chamber 7, respectively. The cylinder 18 on the fixed plate 17 is activated, driving the drive column 23 upwards. Through the drive bar 24 and the fourth gear 21, the flip handle 22 rotates, thereby causing the clamping blocks 51 to grip the outer cylinder of the shock absorber. Then, the electric push rod 12 drives the lifting plate 11 upwards, removing the cleaned and wiped outer cylinder from the cleaning cabinet 2. At this time, the starter motor 14 drives the screw to rotate, and the moving seat 16 moves to the left on the rotating screw, causing the two sets of clamping blocks 51 to move into the wiping chamber 7 and the storage chamber 8, respectively. At this time, the electric push rod 12 drives the lifting plate 11 downwards, transferring the cleaned outer cylinder to the wiping chamber 7 for wiping, while simultaneously transferring the wiped outer cylinder from the wiping chamber 7 to the storage chamber 8 for storage.

[0017] See Figures 1-9The rinsing structure includes: a pressurized liquid supply chamber 4 installed on the right side of the cleaning cabinet 2; a liquid supply pipe 5 connected and fixedly inserted into the cleaning chamber 6; rotating sealed pipe ends 25 are provided at both ends of the liquid supply pipe 5; a rinsing cylinder 26 is provided on each of the two rotating sealed pipe ends 25; a top plate 27 is provided at the top of the rinsing cylinder 26; a first brush body 28 is provided on the top plate 27; a set of second brush bodies 29 and a drain nozzle 30 are provided on the upper side of the rinsing cylinder 26; the drain nozzle 30 and the second brush body 29 are spaced apart from each other; a first pulley 32 is fixedly sleeved on each rinsing cylinder 26 near the bottom; a first belt 33 is tightened between two first pulleys 32; a support plate 31 is fixedly sleeved on each rinsing cylinder 26 near the first pulley 32; and a second gear 37 is fixedly sleeved on the rinsing cylinder 26 near the first pulley 32. The inner wiping structure includes two cleaning rods rotatably connected to the lower inner wall of the wiping chamber 7, with a wiping sleeve 42 fitted onto each cleaning rod; the outer wiping structure includes a rotating cylinder 43 rotatably fitted onto the cleaning rods, with a turntable 44 fixedly fitted at the top of the rotating cylinder 43, the turntable 44 rotating through the second baffle 10; two fixing rods 45 connected to the turntable 44, one end of the fixing rods 45 connected to a fixing strip 46, and a wiping strip 47 provided on one side of the fixing strip 46; a second pulley 48 fixedly fitted at the bottom of each rotating cylinder 43, with a second belt 49 fitted between the two second pulleys 48; and a third gear 50 fixedly fitted on the rotating cylinder 43 near the second pulley 48. The rotating structure includes: two rotating rods 34 rotatably connected to the lower inner walls of the cleaning chamber 6 and the wiping chamber 7, respectively. Each rotating rod 34 is fixedly fitted with a first gear 35, one of which meshes with a third gear 50, and the other with a second gear 37. A transmission cylinder 38 is movably fitted at the top of the rotating rod 34. A collar 40 is provided at the bottom of the transmission cylinder 38. A rod 41 is fixedly inserted into the collar 40. A spiral groove 36 is provided on the rotating rod 34. One end of the rod 41 is slidably disposed in the spiral groove 36. A top block 39 is provided at the top of the transmission cylinder 38. The transmission structure includes a connecting rod 53 connected to the top block 39, one end of which is connected to a U-shaped plate 52. The U-shaped plate 52 is fixedly installed on the lifting plate 11. During rinsing, the cleaning fluid in the pressurized supply chamber 4 is introduced into the rinsing cylinder 26 and sprayed out from the drain nozzle 30 on the rinsing cylinder 26 towards the inner wall of the outer cylinder. As the lifting plate 11 moves up and down, the connecting rod 53 drives the transmission cylinder 38 to move up and down on the rotating rod 34, causing one end of the insert rod 41 on the collar 40 to slide in the spiral groove 36. The insertion rod 41 squeezes the groove wall of the spiral groove 36, pushing the rotating rod 34 to rotate. Under the action of the first gear 35 and the second gear 37, one of the rinsing cylinders 26 is driven to rotate. The pulley 32 and the first belt 33 drive the other rinsing cylinder 26 to rotate synchronously. As the clamped outer cylinder moves up and down on the rinsing cylinder 26, the drain nozzle 30, the first brush body 28 and the second brush body 29 clean various positions of the inner wall of the outer cylinder. At the same time, under the action of another first gear 35 and the third gear 50, one of the rotating cylinders 43 is driven to rotate. In conjunction with the second pulley 48 and the second belt 49, the other rotating cylinder 43 is driven to rotate synchronously. This causes the inner and outer cylinders of the wiping chamber 7 to move up and down on the wiping sleeve 42 and the rotating wiping strip 47, thereby wiping the residual cleaning liquid on the inner and outer walls of the outer cylinder at the same time. This reduces the problem of secondary pollution of the outer cylinder after cleaning and also improves the quality of the working environment.

[0018] The implementation principle of the inner wall cleaning mechanism for the outer cylinder of a shock absorber according to an embodiment of the present invention is as follows: The cylinder 18 on the fixed plate 17 is activated, causing the driving column 23 to move upwards. Through the driving bar 24 and the fourth gear 21, the rotating handle 22 rotates, thereby causing the clamping block 51 to grip the outer cylinder of the shock absorber. The outer cylinder before and after cleaning is inserted into the cleaning chamber 6 and the wiping chamber 7, respectively. Then, the cleaning fluid in the pressurized supply chamber 4 is introduced into the rinsing cylinder 26, and the rinsing fluid is sprayed out from the drain nozzle 30 on the rinsing cylinder 26 towards the inner wall of the outer cylinder for rinsing, and the mechanism is raised and lowered. During the up-and-down movement of plate 11, the connecting rod 53 drives the transmission cylinder 38 to move up and down on the rotating rod 34, causing one end of the insert rod 41 on the collar 40 to slide in the spiral groove 36. The insertion rod 41, by pressing against the wall of the spiral groove 36, pushes the rotating rod 34 to rotate. Under the action of the first gear 35 and the second gear 37, one of the rinsing cylinders 26 rotates. Through the first pulley 32 and the first belt 33, the other rinsing cylinder 26 rotates synchronously. Thus, while the clamped outer cylinder moves up and down on the rinsing cylinder 26, the drain nozzle 30, the first brush body 28, and the second brush body 29 clean various positions on the inner wall of the outer cylinder. Simultaneously, under the action of another first gear 35 and the third gear 50, one of the rotating cylinders 43 rotates. This, in conjunction with the second pulley 48 and the second belt 49, drives the other rotating cylinder 43 to rotate synchronously. This causes the inner and outer cylinders of the wiping chamber 7 to move up and down on the wiping sleeve 42 and the rotating wiping strip 47, thereby simultaneously wiping the residual cleaning liquid on the inner and outer walls of the outer cylinder. At the end of the cleaning and wiping work, the electric... Push rod 12 drives lifting plate 11 to move upward, removing the cleaned and wiped outer cylinder from cleaning cabinet 2. At this time, start motor 14 drives screw to rotate, and moving seat 16 moves to the left on the rotating screw, so that the two sets of clamping blocks 51 move to wiping chamber 7 and storage chamber 8 respectively. At this time, electric push rod 12 drives lifting plate 11 to move downward, transferring the cleaned outer cylinder to wiping chamber 7 for wiping, and transferring the wiped outer cylinder in wiping chamber 7 to storage in storage chamber 8. In this way, the cleaning work of shock absorber outer cylinder can be realized.

[0019] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
