Description

Technical Field

[0001] This utility model relates to the technical field of shock absorber accessory cleaning equipment, and in particular to a batch cleaning device for shock absorber pistons. Background Technology

[0002] The term "shock absorber" is a common term in the automotive chassis industry. An automotive shock absorber is essentially a vibration damper. Shock absorbers are used not only in the suspension of automobiles but also in other locations, such as the driver's cab, seats, steering wheel, and as bumpers. The shock absorber piston is a crucial component, requiring high strength and rigidity. Existing shock absorber pistons often fail during operation due to insufficient strength and rigidity, affecting the normal functioning of the shock absorber. Traditional shock absorber pistons are manufactured using casting or powder metallurgy pressing methods. The resulting piston components typically do not meet the standards for direct use in terms of dimensional accuracy, surface contour, and surface finish. Therefore, secondary processing through finishing processes is necessary to improve production quality.

[0003] However, piston components after secondary finishing typically have a large amount of oil, metal shavings, and dust on their surface, resulting in poor cleanliness. Post-processing cleaning is necessary. Current piston component cleaning methods often involve manual rinsing or batch cleaning in cleaning tanks. Piston components piled in large quantities in cleaning baskets or areas easily overlap, leaving some surfaces uncleaned and leading to poor overall cleaning efficiency. Furthermore, existing cleaning lines cannot reverse-side-clean roughly circular piston components, resulting in incomplete cleaning of the lower surface and requiring secondary reverse-side cleaning, extending the cleaning cycle. Moreover, the current piston component flipping operation is usually done manually, which is slow and reduces overall cleaning efficiency. Finally, pistons typically lack flat sides. Current top-side rinsing methods only clean two sides of circular piston components, often missing sides that cannot directly contact the water jet, thus failing to effectively clean the side contours and resulting in poor overall cleaning quality. Utility Model Content

[0004] The purpose of this invention is to provide a batch cleaning device for shock absorber pistons that can continuously and thoroughly rinse the top and sides of a large number of piston components, thereby improving rinsing efficiency and quality. It can also automatically flip the piston components to effectively rinse their bottom surfaces. This addresses the shortcomings of existing cleaning equipment, such as cleaning tanks, which often result in piston components stacking and partially obscuring each other during batch cleaning, leading to poor cleaning quality. Furthermore, existing cleaning lines require manual flipping of piston components, extending the cleaning cycle and reducing efficiency. The manual operation is also inconsistent and unsuitable for large-scale continuous processing. Additionally, existing cleaning lines cannot effectively clean the sides of piston components, easily overlooking rinsing dead zones and resulting in poor rinsing quality.

[0005] The technical solution adopted by this utility model is as follows: a batch cleaning device for shock absorber pistons, including a processing box shell capable of forming a shielding and protective space to intercept splashed droplets, a support base provided at the bottom of the processing box shell, and a collection tank provided on the support base capable of communicating with the shell cavity of the processing box shell to collect cleaning waste liquid, a flipping conveying assembly capable of forming a stepped conveying plane passing through the processing box shell, and a high-pressure rinsing assembly and a cleaning brush provided on the inner top surface of the processing box shell, wherein the high-pressure rinsing assembly and the cleaning brush are arranged alternately; alignment rinsing assemblies capable of high-pressure rinsing the sides of the piston element are provided on both sides of the flipping conveying assembly.

[0006] According to a preferred embodiment, the flipping conveying assembly includes a high-position conveying mechanism, a low-position conveying mechanism, and a ramp flipping mechanism. The high-position conveying mechanism and the low-position conveying mechanism are arranged between the aligning side walls of the processing housing in such a way that a step-like conveying plane is formed by the height difference between the two conveying surfaces defined by them. The ramp flipping mechanism is also provided between the high-position conveying mechanism and the low-position conveying mechanism, which can construct a guide ramp between the two conveying surfaces with a height difference and adjustably push the piston element on the guide ramp to flip.

[0007] According to a preferred embodiment, the end of the high-position conveying mechanism away from the low-position conveying mechanism passes through the high-position through-hole of the processing box shell, and the end of the low-position conveying mechanism away from the high-position conveying mechanism passes through the low-position through-hole of the processing box shell.

[0008] According to a preferred embodiment, both the first conveyor belt of the high-level conveyor mechanism and the second conveyor belt of the low-level conveyor mechanism are mesh-perforated belts that facilitate the collection of cleaning waste liquid in the collection tank.

[0009] According to a preferred embodiment, the ramp overturning mechanism includes a mounting plate, a guide ramp, a positioning support rod, an inclined push rod, and a guide sleeve. The mounting plate is installed inside the processing housing. The guide ramp, which guides a piston element to slide directionally between the first conveyor belt and the second conveyor belt, is supported on the mounting plate by the positioning support rod. The guide sleeve is inserted into the guide ramp through the plate body, and an inclined push rod, which can extend out of its cavity and push the piston element on the surface of the guide ramp to overturn, is also inserted into the guide sleeve.

[0010] According to a preferred embodiment, an arc-shaped blocking strip is provided at the inclined lower edge of the guide plate to intercept the sliding piston element, and a buffer rubber layer is provided on the surface of the arc-shaped blocking strip that contacts the piston element.

[0011] According to a preferred embodiment, at least two hollow infusion plates of the high-pressure flushing assembly are suspended above the first conveyor belt and the second conveyor belt by a first lifting rod installed on the inner top surface of the processing box shell, respectively. A liquid supply pipe is inserted into the top surface of the hollow infusion plate, and a plurality of first high-pressure nozzles are inserted into the bottom surface of the hollow infusion plate at staggered points.

[0012] According to a preferred embodiment, the alignment flushing assembly includes hollow positioning blocks aligned and installed on two parallel inner surfaces of the processing housing, a liquid supply tube communicating with the hollow positioning blocks, and second high-pressure nozzles spaced apart on the opposing surfaces of the two hollow positioning blocks.

[0013] According to a preferred embodiment, the strip-shaped brush body of the cleaning brush is suspended above the transmission surface defined by the first and second conveyor belts by a second lifting rod mounted on the inner top surface of the processing housing.

[0014] According to a preferred embodiment, an airflow purging mechanism capable of purging and removing water from the piston element is provided above the low-level through-hole of the processing housing.

[0015] The beneficial effects of this utility model are:

[0016] The high-level and low-level conveying mechanisms in this application are located upstream and downstream of the inclined tilting mechanism, respectively, to perform high-pressure rinsing on both end faces of the piston elements before and after tilting, ensuring the quality and effectiveness of the rinsing. The high-level and low-level conveying mechanisms in this application can continuously transport piston elements. Compared to existing tank-type cleaning equipment, the conveying structure can separate and arrange the piston elements, avoiding overlap between piston elements that prevents direct contact with the high-pressure liquid flow for rinsing, resulting in poor rinsing effects and ineffective coverage of the piston element surface by the high-pressure rinsing liquid flow. This enables continuous cleaning of batches of piston elements, shortens the cleaning cycle, and improves the efficiency of large-scale cleaning. In particular, the inclined tilting mechanism can transfer piston elements between the high-level and low-level conveying mechanisms while simultaneously tilting them, ensuring that both end faces of the piston elements are effectively cleaned. This avoids the defect in traditional cleaning lines where the bottom surface of the piston elements is obstructed and cannot be thoroughly cleaned, improving cleaning quality and comprehensiveness. The ramp tilting mechanism can periodically and automatically complete the tilting operation of the directional conveying piston element, effectively reducing the need for manual intervention, improving overall automation and continuous processing performance, and increasing operating speed and overall cleaning efficiency.

[0017] The second high-pressure nozzle provided in this application can spray high-pressure flushing fluid streams in opposite directions, so that the side of the piston element passing between the high-pressure flushing fluid streams can obtain an effective flushing and cleaning effect, thereby improving the comprehensiveness and cleaning quality of the entire surface of the piston element.

Detailed Implementation

[0023] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0024] The following is a detailed explanation with reference to the accompanying drawings. Example

[0025] This application provides a batch cleaning device for shock absorber pistons, which includes a processing housing 1, a support base 2, a liquid collection tank 3, a flipping conveyor assembly 4, a high-pressure flushing assembly 5, a cleaning brush 6, and an alignment flushing assembly 7.

[0026] according to Figure 1-3In one specific embodiment, the processing housing 1 forms a protective shielding space to intercept cleaning droplets splashing during rinsing. A support base 2 is provided at the bottom of the processing housing 1. A collection tank 3, communicating with the cavity of the processing housing 1, is provided on the support base 2 to collect cleaning waste liquid. A tilting conveyor assembly 4, forming a stepped conveying plane, is installed on the processing housing 1. A high-pressure rinsing assembly 5 and a cleaning brush 6 are also provided on the inner top surface of the processing housing 1. The high-pressure rinsing assembly 5 and the cleaning brush 6 are arranged alternately. Alignment rinsing assemblies 7, capable of high-pressure rinsing the sides of the piston element, are provided on both sides of the tilting conveyor assembly 4. The high-pressure rinsing assembly 5 and the rinsing assembly 7 are connected to the same high-pressure washer product via parallel inlet pipes, and an electromagnetic switching valve is provided on the branch pipe of the inlet pipe to limit the delivery of rinsing liquid to the high-pressure rinsing assembly 5 and / or the rinsing assembly 7. The high-pressure rinsing assembly 5 and the rinsing assembly 7 can also be connected to different high-pressure cleaner products, so that different high-pressure cleaners can independently provide rinsing fluid with different fluid pressures.

[0027] Preferably, a high-level through-hole 11 and a low-level through-hole 12 are respectively provided on the left and right side walls of the processing housing 1. More preferably, an airflow purging mechanism 13 capable of purging and removing water from the piston element is provided above the low-level through-hole 12 of the processing housing 1. Preferably, the airflow purging mechanism 13 includes a clean high-pressure gas tank, a guide pipe, and an exhaust strip. The clean high-pressure gas tank is used to store high-pressure clean gas, and it is connected to the exhaust strip through the guide pipe. The lower surface of the exhaust strip is provided with multiple inclined jet nozzles at intervals, so that it can output a clean airflow curtain covering the entire low-level through-hole 12 from top to bottom, thereby allowing the clean airflow to blow away most of the residual rinsing liquid on the surface of the piston element passing through the low-level through-hole 12, thereby improving the dryness of the piston element and preventing residual cleaning liquid from dripping everywhere during the transfer of the piston element. Preferably, the alignment side walls mentioned in this application refer to the front and rear side walls of the processing housing 1.

[0028] Preferably, a collection tray 21 is symmetrically provided on the support base 2 to collect the cleaning waste liquid dripping from the first conveyor belt 411 and the second conveyor belt 421 in the outer section of the processing box shell 1.

[0029] Preferably, the collection tank 3 is connected to an external water treatment device through an interface valve and a water pump, so as to purify the collected clean waste liquid, thereby facilitating the secondary recycling of the purified liquid, reducing the waste of water resources, and preventing the pollution of water resources and the environment caused by the direct discharge of waste liquid.

[0030] Preferably, the flipping conveyor assembly 4 includes a high-level conveyor mechanism 41, a low-level conveyor mechanism 42, and a ramp flipping mechanism 43. Preferably, the high-level conveyor mechanism 41 and the low-level conveyor mechanism 42 are arranged between the opposing side walls of the processing housing 1 in a stepped conveying plane formed by a height difference between the two conveying surfaces they define. More preferably, the end of the high-level conveyor mechanism 41 away from the low-level conveyor mechanism 42 passes through the high-level through-hole 11 of the processing housing 1. More preferably, the end of the low-level conveyor mechanism 42 away from the high-level conveyor mechanism 41 passes through the low-level through-hole 12 of the processing housing 1. Preferably, a ramp flipping mechanism 43 is further provided between the high-level conveyor mechanism 41 and the low-level conveyor mechanism 42, which can construct a guide ramp between the two conveying surfaces with a height difference and adjustably push the piston element on the guide ramp to flip. The high-level conveying mechanism 41 and low-level conveying mechanism 42 of this application are respectively located upstream and downstream of the inclined tilting mechanism 43, thereby performing high-pressure rinsing on both end faces of the piston element before and after tilting to ensure the quality and effect of rinsing. The high-level conveying mechanism 41 and low-level conveying mechanism 42 of this application can continuously convey piston elements. Compared with existing cleaning tank-type cleaning equipment, the conveying structure can separate and place the piston elements, avoiding the problems of piston elements touching or overlapping and failing to directly contact the high-pressure liquid flow for rinsing, resulting in poor rinsing effect and the high-pressure rinsing liquid flow failing to effectively cover the surface of the piston elements. This enables continuous cleaning of batches of piston elements, shortens the cleaning cycle, and improves the efficiency of large-scale cleaning. In particular, the inclined tilting mechanism 43 can transfer piston elements between the high-level conveying mechanism 41 and the low-level conveying mechanism 42 while also tilting the piston elements, thereby ensuring that both end faces of the piston elements can be effectively cleaned. This avoids the defect of traditional cleaning lines where the bottom surface of the piston elements is blocked and cannot be thoroughly cleaned, improving cleaning quality and comprehensiveness. The ramp tilting mechanism 43 can periodically and automatically complete the tilting operation of the piston element for directional conveying, effectively reducing the need for manual intervention, improving the overall automation and continuous processing performance, and increasing the operating speed and overall cleaning efficiency.

More preferably, the first conveyor belt 411 is sleeved on the two first rollers 412 and passes through the high-level through-hole 11. More preferably, a first drive motor 413 capable of driving the first roller 412 to rotate is also installed on the outer wall of the processing housing 1.

[0032] Preferably, the low-position conveying mechanism 42 includes a second conveyor belt 421, a second roller 422, a second drive motor 423, and a second support rod 424. More preferably, the second roller 422 located outside the processing housing 1 is suspended and supported by the second support rod 424 connected to the outer side of the processing housing 1, and both axial ends of the other second roller 422 are rotatably inserted into the corresponding side wall of the processing housing 1. More preferably, the second conveyor belt 421 is sleeved on the two second rollers 422 and passes through the low-position through-hole 12. More preferably, a second drive motor 423 capable of driving the second rollers 422 to rotate is also installed on the outer wall of the processing housing 1.

In a preferred embodiment, first anti-slip barriers and second anti-slip barriers are respectively provided at intervals on the surfaces of the first conveyor belt 411 and the second conveyor belt 421 to limit the synchronous conveying state of the piston element. By setting the first conveyor belt 411 and the second conveyor belt 421 as perforated mesh belt structures, this application facilitates the dripping of rinsing liquid through the belt, thereby reducing the residue of cleaning waste liquid on the belt and improving the collection effect and recyclability of the waste liquid.

[0034] Preferably, the ramp tilting mechanism 43 includes a mounting plate 431, a guide ramp 432, a positioning support rod 433, an inclined push rod 434, and a guide sleeve 435. Preferably, the mounting plate 431 is suspended inside the processing housing 1. More preferably, the two sides of the mounting plate 431 are fixedly abutted against the corresponding side wall of the processing housing 1. Preferably, the mounting plate 431 is supported by the positioning support rod 433 on the guide ramp 432, which can position the two ends of the plate at the edges of the transmission surfaces defined by the first conveyor belt 411 and the second conveyor belt 421, respectively, to form a guide ramp that guides the piston element to slide directionally between the first conveyor belt 411 and the second conveyor belt 421. Preferably, the guide sleeve 435 is inserted into the guide ramp 432 through the plate. More preferably, an inclined push rod 434 is also inserted into the guide sleeve 435, which can extend out of its cavity and push the piston element on the plate surface of the guide ramp 432 to tilt. Specifically, the inclined lower end of the tilting push rod 434 is detachably mounted on the mounting plate 431. The tilting push rod 434 is an automatic telescopic rod of model OSS2025. Preferably, an arc-shaped blocking strip 4321 capable of intercepting the sliding piston element is also provided on the inclined lower edge of the guide plate 432. More preferably, a buffer rubber layer 4322 is provided on the surface of the arc-shaped blocking strip 4321 that contacts the piston element. The tilting push rod 434 provided in this application can extend from the guide plate 432 and push the piston element intercepted by the arc-shaped blocking strip 4321 on the guide plate 432 to flip over, so that the piston element can flip over and lie flat on the second conveyor belt 421. The transfer of the piston element to the second conveyor belt 421 is completed automatically while the piston element is flipped over to expose the bottom surface of the piston element when it is on the first conveyor belt 411. Thus, the high-pressure flushing assembly 5 on the second conveyor belt 421 can effectively flush and clean the bottom surface of the piston element that has not been cleaned by the previous cleaning structure. To ensure effective and thorough cleaning.

[0035] Preferably, at least two hollow infusion plates 51 of the high-pressure flushing assembly 5 are suspended above the first conveyor belt 411 and the second conveyor belt 421 by first lifting rods 52 installed on the inner top surface of the processing housing 1. Preferably, a supply pipe 53 is inserted into the top surface of the hollow infusion plate 51. Preferably, the supply pipe 53 is a high-pressure infusion pipe product with a certain degree of reconfigurability to facilitate changes in its length and pipe shape. Preferably, a plurality of first high-pressure nozzles 54 are staggered and arrayed on the bottom surface of the hollow infusion plate 51. The first lifting rod 52 provided in this application can drive the hollow infusion plate 51 to adjust its height, thereby changing the vertical distance between the first high-pressure nozzles 54 on the hollow infusion plate 51 and the piston element, thus ensuring the flushing effect on the piston element. Preferably, the first lifting rod 52 and the second lifting rod 62 are electric push rods of model YLK11. The first high-pressure nozzle 54 provided in this application can effectively cover the piston element that moves directionally with the conveyor belt by means of several streams of high-pressure flushing liquid from top to bottom through a staggered array arrangement, so that the upper surface of the piston element can be effectively and thoroughly flushed and cleaned.

[0036] Preferably, the strip brush body 61 of the cleaning brush 6 is suspended above the transmission surface defined by the first conveyor belt 411 and the second conveyor belt 421 via a second lifting rod 62 mounted on the inner top surface of the processing housing 1. The strip brush body 61 provided in this application can adaptably contact the surface of the piston element under the adjustment of the second lifting rod 62, thereby brushing away stains and impurities adhering to the surface of the piston element to improve cleaning effect and quality. The strip brush body 61 provided in this application can form relative movement with the piston element that moves along with the conveyor belt, thereby improving the brushing effect.

[0037] Preferably, the alignment flushing assembly 7 includes hollow positioning blocks 71 aligned and mounted on two parallel inner surfaces of the processing housing 1, a liquid supply pipe 72 communicating with the hollow positioning blocks 71, and second high-pressure nozzles 73 spaced apart on the opposing surfaces of the two hollow positioning blocks 71. Preferably, the second high-pressure nozzle 73 is a nozzle structure with a vertical strip-shaped drain outlet. The second high-pressure nozzle 73 provided in this application can spray high-pressure flushing liquid streams in opposite directions, so that the side of the piston element passing between the high-pressure flushing liquid streams can obtain an effective flushing and cleaning effect, improving the comprehensiveness and cleaning quality of the entire surface of the piston element. In particular, the piston element of this application is round, so that the alignment flushing liquid stream can effectively traverse its entire side, without any grooves that are blocked and cannot directly contact the lateral flushing liquid stream, ensuring the side flushing effect.

[0038] The electrical components involved in this application, such as the first drive motor 413, the second drive motor 423, the first lifting rod 52, and the second lifting rod 62, are all electrically connected to the controller and the power supply.
