Description

Technical Field

[0001] This application relates to the field of automotive shock absorber technology, specifically to an adhesive pressing device for automotive shock absorber liner assembly. Background Technology

[0002] The liner assembly of an automotive shock absorber is a key structural component that provides support, guidance, and sealing within the shock absorber. It typically consists of an inner liner, an outer liner (some designs include this), a guide sleeve, seals, and buffer components.

[0003] Currently, the production and processing of liner components requires gluing and pressing operations, which are generally carried out separately on different platforms. This involves the handling, positioning, and re-fixing of the liner components, which significantly reduces production efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose an adhesive pressing device for automotive shock absorber liner assembly, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides an adhesive application and pressing device for automotive shock absorber liner assemblies, comprising a device platform, a pinion rotatably connected to the device platform, a processing cylinder fixedly inserted through the inner side of the pinion, a sponge pad provided on the inner wall of the processing cylinder, an overflow plate fixedly fitted on the outer surface of the processing cylinder, a self-rotating mechanism provided on the device platform, a horizontal plate fixedly connected to the inner side of the device platform, a force-applying rod movably inserted through the inner side of the horizontal plate, a pressure head fixedly connected to the bottom of the force-applying rod, and a driving pressure mechanism provided on the device platform.

[0006] Preferably, the spin mechanism includes a large gear rotatably connected to the device platform, and a handle is fixedly connected to the top of the large gear. The spin mechanism enables each processing cylinder to rotate, thereby allowing the sponge pad coated with adhesive to adhere to the shock absorber liner during the rotation.

[0007] Preferably, a rack is slidably connected to the inner side of the device platform, the outer surface of the rack meshing with the outer surface of the large gear, and the outer surface of the rack meshing with the outer surface of the small gear.

[0008] Preferably, the driving and pressurizing mechanism includes a drive plate fixedly connected to the top of the force-applying rod, and a spring is movably sleeved on the outer surface of the force-applying rod. The driving and pressurizing mechanism can apply a certain force to the shock absorber liner from the top to achieve the effect of pressing the liner.

[0009] Preferably, a motor is fixedly installed at one end of the device platform, and a drive gear is fixedly connected to the output end of the motor. A transmission gear is meshed with the outer surface of the drive gear.

[0010] Preferably, a rotating shaft is fixedly connected to the center of the transmission gear, and an eccentric wheel is provided on the rotating shaft, with three sets of eccentric wheels.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This automotive shock absorber liner assembly adhesive pressing device completes the two key processes of pressing and adhesive application with a single device. It integrates the adhesive application and pressing operations into the same device, eliminating the need to move the liner back and forth to different processing platforms. This simplifies the production process, avoids cumbersome handling, positioning and re-fixing operations, significantly shortens the production cycle, and significantly improves overall production efficiency.

[0013] 2. In this automotive shock absorber liner assembly adhesive pressing device, the long shaft of the eccentric wheel gradually contacts the drive plate, and the spring provides the initial preload to ensure that the liner assembly is initially positioned. The tip of the eccentric wheel continuously applies pressure, and the spring deformation changes in real time with the compression of the adhesive layer, forming a "pressure-displacement" closed-loop feedback to avoid damage to the liner or adhesive layer from rigid impacts and to achieve dynamic adaptive adjustment of the pressing force.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] Please see Figure 1-2A device for applying adhesive to and pressing an automotive shock absorber liner assembly includes a platform 1, a pinion 2 rotatably connected to the platform 1, a processing cylinder 3 fixedly inserted through the inner side of the pinion 2, the processing cylinder 3 being a completely hollowed-out design (i.e., the entire processing cylinder 3 is designed like a pipe), a sponge pad 4 is provided on the inner wall of the processing cylinder 3, an overflow plate 5 is fixedly fitted on the outer surface of the processing cylinder 3, the overflow plate 5 is responsible for collecting adhesive overflowing from inside and outside the processing cylinder 3, a self-rotating mechanism is provided on the platform 1, a horizontal plate 9 is fixedly connected to the inner side of the platform 1, a force-applying rod 10 is movably inserted through the inner side of the horizontal plate 9, a pressure head 11 is fixedly connected to the bottom of the force-applying rod 10, and a driving pressure mechanism is provided on the platform 1.

[0019] With the above technical solution, when the device is in use, the shock absorber liner is first placed in each processing cylinder 3. By driving the pressurizing mechanism, the pressurizing head 11 can be moved down to press the liner. When applying glue, the pressurizing mechanism is driven to apply a certain force to the liner with the pressurizing head 11. With the help of the spin mechanism, the sponge pad 4 coated with glue can be repeatedly contacted with the outer circumference of the liner during the spin process, thereby completing the glue application operation.

[0020] Specifically, the spin mechanism includes a large gear 6 rotatably connected to the device platform 1, and a handle 7 is fixedly connected to the top of the large gear 6.

[0021] With the above technical solution, rotating the handle 7 can drive the large gear 6 to rotate. The large gear 6 and the small gear 2 are both meshed with the rack 8, so the small gear 2 will drive the processing cylinder 3 to rotate synchronously.

[0022] Specifically, a rack 8 is slidably connected to the inner side of the device platform 1. The outer surface of the rack 8 meshes with the outer surface of the large gear 6, and the outer surface of the rack 8 meshes with the outer surface of the small gear 2.

[0023] Through the above technical solution, the function of rack 8 is to convert the rotation of large gear 6 into the rotation of small gear 2. During the sliding process of rack 8 inside the device platform 1, it will simultaneously drive three small gears 2 to rotate synchronously.

[0024] Specifically, the driving pressurization mechanism includes a drive plate 12 fixedly connected to the top of the force-applying rod 10, and a spring 13 movably sleeved on the outer surface of the force-applying rod 10.

[0025] Through the above technical solution, the end of the drive plate 12 that contacts the eccentric wheel 18 is designed with an arc shape. This is to ensure that the eccentric wheel 18 and the drive plate 12 are always in stable contact. The drive plate 12, the eccentric wheel 18 and related components are provided in three sets, which are to correspond to the three sets of machining cylinders 3 and pinions 2.

[0026] Specifically, a motor 14 is fixedly installed at one end of the device platform 1, and a drive gear 15 is fixedly connected to the output end of the motor 14. A transmission gear 16 is meshed with the outer surface of the drive gear 15.

[0027] Through the above technical solution, when the motor 14 drives the drive gear 15 to rotate, it will be linked to the transmission gear 16 to rotate, which will eventually drive the rotating shaft 17 to rotate. During this period, the three sets of eccentric wheels 18 will rotate synchronously.

[0028] Specifically, a rotating shaft 17 is fixedly connected to the shaft center of the transmission gear 16, and an eccentric wheel 18 is provided on the rotating shaft 17, with three sets of eccentric wheels 18.

[0029] Through the above technical solution, during the rotation of the eccentric wheel 18, when the opposite tip of the eccentric wheel 18 gradually approaches the drive plate 12, the drive plate 12 will be gradually driven to move downward and compress the spring 13. During this process, the force rod 10 and the pressure head 11 gradually move downward, and the pressure applied by the pressure head 11 to the liner will also increase.

[0030] Working principle: During the processing of the shock absorber liner, three liners are first placed into three processing cylinders 3 respectively. Then, the motor 14 is turned on to drive the drive gear 15 to rotate. The drive gear 15 drives the transmission gear 16, which meshes with it, to rotate synchronously, and finally drives the rotating shaft 17 to rotate. During the rotation of the rotating shaft 17, it drives three sets of eccentric wheels 18 to rotate synchronously. When the eccentric wheel 18 is at its highest position (e.g., ...), the rotation continues. Figure 1 As the part (shown) gradually approaches the drive plate 12, the drive plate 12 is driven to move downwards. During this process, the force rod 10 and the pressure head 11 move downwards synchronously, and the spring 13 is gradually compressed. When the tip of the eccentric wheel 18 contacts the drive plate 12, the drive plate 12 is pressed down to its lowest position, and the spring 13 undergoes maximum deformation. At this point, the pressure head 11 applies the maximum force to the liner assembly, thus completing the pressing operation of the liner assembly. When applying adhesive, the liner must first be stabilized in the processing cylinder 3 by the pressure head 11 (at this point, the outer surface of the liner is in contact with the sponge pad 4 and there is a certain amount of pressure). Then, the handle 7 is rotated to drive the large gear. As wheel 6 rotates, the large gear 6 drives the rack 8 to slide inside the device platform 1. The sliding of the rack 8 in turn drives the small gear 2, which meshes with it, to rotate. During this process, the three sets of small gears 2 are driven to rotate synchronously. The processing cylinder 3, which is fixedly mounted on the small gear 2, will also rotate. During this process, the sponge pad 4 on the inner wall of the processing cylinder 3 will rub against the outer circumference of the liner tube, thereby adhering the glue coated on the sponge pad 4 to the outer circumference of the liner tube, thus completing the gluing operation of the shock absorber liner tube. During the entire pressing and gluing process, there is no need to move the liner tube back and forth to different processing platforms, avoiding tedious handling, positioning and re-fixing operations, which greatly improves production efficiency.
