Technical Field

[0001] This utility model relates to the field of cleaning technology for continuous damping control shock absorbers, specifically to a cleaning device for shock absorber production. Background Technology

[0002] Continuous damping control shock absorbers are shock absorber elements that can continuously adjust the damping force in real time. Because they can adaptively adjust the damping in real time and have a fast response speed, they are widely used in the automotive manufacturing field.

[0003] During the production process of continuous damping control shock absorbers, due to handling or long-term storage, tiny impurities can easily adhere to the port surface of the shock absorber. After the sealing process is completed, the impurities that were originally left on the sealing end face will turn into dust after the sealing rolling process and adhere to the sealing end surface of the continuous damping control shock absorber. The attached dust is very easy to mix with the inflation gas in the subsequent inflation process, thus entering the inside of the shock absorber and affecting the overall cleanliness of the product and its subsequent performance. Utility Model Content

[0004] The purpose of this utility model is to provide a cleaning device for shock absorber production, in order to solve the technical problem in the prior art that when a continuous damping control shock absorber is inflated after the sealing process, the dust attached to the sealing end is easily mixed with the inflation gas and enters the interior of the shock absorber, affecting the overall cleanliness of the product and its subsequent performance.

[0005] This utility model proposes a cleaning device for shock absorber production, including a cleaning component disposed above the conveying mechanism for removing dust from the sealing end of the shock absorber.

[0006] The cleaning component includes a sealing cover;

[0007] The bottom of the sealing cover is provided with a dust removal chamber, and two sets of air inlets and dust suction ports are provided at equal intervals on the outer wall.

[0008] The two sets of air inlets and the dust suction port are respectively connected to two sets of guide grooves and dust collection grooves opened on the top wall of the dust removal chamber, and the inner wall of the guide groove away from the air inlet is provided with a flow guiding arc surface.

[0009] The dust extraction port is located above the air inlet.

[0010] Preferably, the cleaning assembly further includes a clearance groove formed in the top wall of the dust removal chamber for accommodating the shock absorber piston rod.

[0011] Preferably, the cleaning assembly further includes a fixing plate, a side plate, a limiting plate, and an offset seat;

[0012] The side plates and the two groups of limiting plates are both arranged on the fixed plate. The side plates and the two groups of limiting plates enclose a "C"-shaped limiting structure for guiding and limiting the offset seat.

[0013] The offset seat is slidably arranged between the two groups of limiting plates and is used to support the sealing cover.

[0014] Preferably, the cleaning component further includes a first elastic member. One end of the first elastic member is connected to the side plate, and the other end is connected to the offset seat for elastically supporting the offset seat.

[0015] Preferably, the cleaning component further includes a sliding rod. One end of the sliding rod is connected to the offset seat, and the other end is movably connected to the sealing cover.

[0016] Preferably, the cleaning component further includes a second elastic member. The second elastic member is sleeved outside the sliding rod for elastically supporting the sealing cover.

[0017] Preferably, there is also a jacking mechanism for jacking up the shock absorber fixing tooling transported on the conveying mechanism. The jacking mechanism includes a base and a first-level top plate. The first-level top plate is movably arranged on the top of the base and has at least one set of guide shafts penetrating through the base.

[0018] Preferably, the jacking mechanism further includes a second-level top plate. The second-level top plate is movably arranged on the top of the first-level top plate, and multiple positioning pins for positioning the shock absorber fixing tooling are arranged on the top.

[0019] Preferably, there is also a lifting and translation mechanism for driving the cleaning component to move. The lifting and translation mechanism includes a frame and a lifting screw rod.

[0021] Preferably, the lifting and translation mechanism further includes a translation unit. The translation unit is arranged on the follower seat, and a translation seat for installing the cleaning component is arranged at the movable end of the translation unit.

[0022] Compared with the prior art, this utility model has at least the following beneficial effects: In this utility model, the sealing cover forms a partially enclosed space at the sealing end of the shock absorber. Clean gas enters the guide groove from the air inlet, and the guide groove guides the airflow evenly to the sealing end, thereby pneumatically cleaning the dust attached to the sealing end of the shock absorber. At this time, a negative pressure is formed in the dust collection groove area, which can extract the dust and achieve closed collection of dust, avoiding pollution of the cleanroom environment. The guide arc surface opened on the guide groove can form a secondary guide for the airflow, causing the airflow to move downward. When the airflow is blocked by the sealing end of the shock absorber and turns upward, it can carry the falling dust upward to the negative pressure dust collection area, thereby further improving the dust collection effect and preventing the falling dust from being re-adsorbed at the sealing end of the shock absorber. Therefore, when the shock absorber is in the inflation process, the inflation gas will not be mixed with dust and enter the interior of the shock absorber, ensuring the overall cleanliness of the product and its subsequent performance.

The basic principles of this invention as defined in the following description can be applied to other implementations, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this invention.

[0035] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0036] As mentioned in the background art, this application proposes a cleaning device for shock absorber production, used to remove dust from the sealed end of a continuously damped control shock absorber after the sealing process is completed. Since the continuously damped control shock absorber plays a very important role in shock absorption during vehicle operation, when there is dust at the sealed end of the continuously damped control shock absorber, the attached dust is very easy to mix with the inflation gas in the subsequent inflation process, thereby entering the interior of the shock absorber, affecting the overall cleanliness of the product and its subsequent performance, and creating a safety hazard. Therefore, it is necessary to remove dust from the sealed end of the continuously damped control shock absorber.

[0037] For specific details, please refer to... Figures 1 to 6 As shown, this embodiment proposes a cleaning device for shock absorber production, including a cleaning component 4 disposed above the conveying mechanism 1 for dust removal from the sealing end of the shock absorber.

[0038] The cleaning component 4 includes a sealing cover 408.

[0039] The bottom of the sealing cover 408 is provided with a dust removal chamber 409, and two sets of air inlets 411 and dust suction ports 414 are provided through the outer wall at equal intervals.

[0040] The two sets of air inlets 411 and the dust suction port 414 are respectively connected to the two sets of guide grooves 412 and dust collection grooves 415 opened on the top wall of the dust removal chamber 409. Furthermore, the inner wall of the guide groove 412 away from the air inlet 411 is provided with a flow guiding arc surface 413.

[0041] The dust suction port 414 is located above the air inlet 411.

[0042] Specifically, the dust removal chamber 409 and the sealing end of the shock absorber form a partially enclosed space to prevent dust from spreading during the cleaning process. The air inlet 411 is used to connect to an external pneumatic device to deliver clean gas to the guide groove 412. The guide groove 412 guides the airflow to the top surface of the sealing end to form a uniform airflow, which efficiently blows up the dust on the top surface of the sealing end and avoids dust residue.

[0043] Furthermore, the suction port 414 is used to connect to an external negative pressure dust collection device, thereby creating a negative pressure in the dust collection tank 415 area, which can extract the dust and achieve closed collection of the dust to avoid polluting the cleanroom environment.

[0044] Furthermore, the guide arc surface 413 opened on the guide groove 412 can form a secondary guide for the airflow delivered by the air inlet 411, so that the airflow moves downward. When the airflow is blocked by the sealing end of the shock absorber and turns upward, it can carry the falling dust upward to the negative pressure dust collection area, thereby further improving the dust collection effect and preventing the falling dust from being adsorbed on the sealing end of the shock absorber for a second time.

[0045] Furthermore, in this embodiment, the dust collection trough 415 is preferably fan-shaped to ensure a large negative pressure dust collection area, thereby efficiently collecting the dust in the dust removal chamber 409.

[0046] like Figure 5 and Figure 6 As shown, in this embodiment, the cleaning component 4 further includes a clearance groove 410, which is formed on the top wall of the dust removal chamber 409 and is used to match the shock absorber piston rod.

[0047] Specifically, the avoidance groove 410 is matched with the shock absorber piston rod. When the sealing cover 408 seals the sealing end of the shock absorber, the piston rod is inserted into the avoidance groove 410 to prevent movement interference between the two.

[0048] As Figure 2 shown, in this embodiment, the cleaning component 4 further includes a fixing plate 401, a side plate 402, a limiting plate 403 and an offset seat 404.

[0049] The side plate 402 and the two limiting plates 403 are both arranged on the fixing plate 401. The side plate 402 and the two limiting plates 403 enclose a "C"-shaped limiting structure for guiding and limiting the offset seat 404.

[0050] The offset seat 404 is slidably arranged between the two limiting plates 403 for supporting the sealing cover 408.

[0051] Specifically, a guiding groove is provided on the inner wall of the limiting plate 403 for guiding and limiting the offset seat 404 to ensure that the offset seat 404 can only slide in the horizontal direction and avoid deviation.

[0052] As Figure 2 shown, in this embodiment, the cleaning component 4 further includes an elastic member 405. One end of the elastic member 405 is connected to the side plate 402, and the other end is connected to the offset seat 404 for elastically supporting the offset seat 404.

[0053] Specifically, in this implementation, the elastic member 405 is preferably a spring. The spring is a standard part, which is easy to obtain, has low production cost and relatively low price, and is beneficial to reducing the manufacturing cost of the equipment.

[0054] Furthermore, the elastic member 405 elastically supports the offset seat 404. During normal operation, without external force, under the action of the elastic member 405, the offset seat 404 and the sealing cover 408 are at the reference position, ensuring that the subsequent sealing cover 408 can successfully seal the sealing end of the shock absorber. When the sealing cover 408 is subjected to an external force in the horizontal direction, the elastic member 405 is compressed synchronously to form a buffer stroke, thereby forming good buffer protection for the sealing cover 408.

[0055] As Figure 4 shown, in this embodiment, the cleaning component 4 further includes a sliding rod 406. One end of the sliding rod 406 is connected to the offset seat 404, and the other end is movably connected to the sealing cover 408.

[0056] Specifically, the sliding rod 406 forms a hanging traction for the sealing cover 408 and guides the movement of the sealing cover 408 to avoid deviation.

[0057] like Figure 4 As shown, in this embodiment, the cleaning component 4 further includes an elastic element 407, which is sleeved on the outside of the slide rod 406 to provide elastic support for the sealing cover 408.

[0058] Specifically, in this embodiment, the elastic element 407 is preferably a spring. Springs are standard parts, easy to obtain, and have low production costs and relatively low prices, which helps to reduce the manufacturing cost of the equipment.

[0059] Furthermore, when the sealing cover 408 contacts the sealing end of the shock absorber in the vertical direction, the compression of the elastic element 407 can buffer the contact impact force, preventing the sealing cover 408 from damaging the sealing end of the shock absorber, while ensuring that the sealing cover 408 fits tightly with the sealing end to form a seal.

[0060] Furthermore, when the sealing cover 408 undergoes excessive displacement in the vertical direction, the elastic element 407 can form a stroke compensation area through compression, thereby preventing excessive impact between the sealing cover 408 and the sealing end of the shock absorber, thus providing good protection for both.

[0061] like Figure 1 , Figure 7 and Figure 8 As shown, in this embodiment, a lifting mechanism 2 is also included for lifting the shock absorber fixing fixture 5 transported on the conveying mechanism 1. The lifting mechanism 2 includes a base 201 and a primary top plate 202. The primary top plate 202 is movably disposed on the top of the base 201 and has at least one set of guide shafts passing through the base 201.

[0062] The specific conveying mechanism 1 includes a conveyor frame and two sets of conveyor belts distributed on both sides of the frame to realize the continuous conveying of the shock absorber and ensure that the shock absorber accurately reaches the cleaning station. The two sets of conveyor belts transport the shock absorber fixing fixture 5, so that the bottom central area of ​​the shock absorber fixing fixture 5 is suspended, which facilitates the subsequent lifting mechanism 2 to lift it.

[0063] Furthermore, the base 201 is provided with a power source for driving the first-stage top plate 202 to move. In this embodiment, the power source is preferably a cylinder or a motor. The power source drives the first-stage top plate 202 to move for the initial height adjustment, thereby driving the shock absorber fixing fixture 5 to rise and fall.

[0064] like Figure 1 , Figure 7 and Figure 8As shown, in this embodiment, the lifting mechanism 2 further includes a secondary top plate 203, which is movably disposed on the top of the primary top plate 202, and the top is provided with multiple sets of positioning pins 204 for positioning the shock absorber fixing fixture 5.

[0065] Specifically, the primary top plate 202 is also provided with a power source for driving the secondary top plate 203 to move. In this embodiment, the power source is preferably a cylinder or a motor, and a slot for movement is provided on the base 201 to accommodate the power source provided on the primary top plate 202.

[0066] Furthermore, when the movement stroke of the primary top plate 202 is insufficient to lift the shock absorber fixing fixture 5 to the working position, the secondary top plate 203 rises, thereby driving the shock absorber fixing fixture 5 to perform a secondary movement.

[0067] Furthermore, the bottom of the shock absorber fixing fixture 5 is provided with positioning holes, and the secondary top plate 203 is provided with matching positioning pins 204, so that the stability of the movement of the shock absorber fixing fixture 5 can be further improved during jacking.

[0068] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a lifting and translation mechanism 3 for driving the cleaning component 4 to move is also included. The lifting and translation mechanism 3 includes a frame 301 and a lifting screw 302.

[0069] The lifting screw 302 is movably mounted on one side of the frame 301, and a follower seat 303 for driving the cleaning component 4 to move is movably sleeved on the outer side of the lifting screw 302.

[0070] Specifically, the top of the frame 301 is provided with a power source for driving the lifting screw 302 to move. In this embodiment, the power source is preferably a servo motor, and on the same side of the frame 301 where the lifting screw 302 is provided, a guide rail is also provided for limiting and guiding the follower seat 303.

[0071] Furthermore, under the limiting action of the guide rail, the rotation of the lifting screw 302 can drive the follower seat 303 to move back and forth along the direction of the lifting screw 302, thereby controlling the position of the cleaning component 4 in the vertical direction, so that the sealing cover 408 can accurately cover the sealing end of the continuous damping control shock absorber.

[0072] like Figure 3 and Figure 4As shown, in this embodiment, the lifting and translating mechanism 3 further includes a translating unit 304, which is disposed on the follower seat 303, and the movable end of the translating unit 304 is provided with a translating seat 305 for installing the cleaning component 4.

[0073] Specifically, the translation unit 304 can drive the translation seat 305 to move in the horizontal direction, thereby controlling the position of the cleaning component 4 in the horizontal direction, so that the sealing cover 408 is located directly above the sealing end of the continuous damping control shock absorber to be dusted. In this embodiment, the translation unit 304 is preferably a cylinder.

[0074] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0075] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
