Description

Technical Field

[0001] The invention relates to the technical field of shock absorber accessory production, in particular to a semi-automatic pressing device for a damper assembly. Background Art

[0002] As a key component for shock absorption and wear resistance, bushings are widely used in mechanical transmission systems (such as electric vehicle rear wheel forks, automobile suspensions, industrial bearings, etc.). The quality of their pressing directly affects the life and performance of the equipment. Bushings need to be installed on both ends of the shock absorber damper for subsequent assembly. The bushings and mounting holes usually need to be tightly fixed through interference fit. The traditional process relies on pressure pressing (hydraulic or mechanical pressure), which has extremely high requirements for concentricity and pressure control accuracy.

[0003] In the prior art, a hydraulic system is generally used to drive a pressure head to press the bushing into the hole of a workpiece, and mechanical guidance is relied upon to ensure positioning. The interior of some bushings is hexagonal, and during the clamping process, it is necessary to adjust the positions of the mounting rings at both ends of the damper. However, due to the lack of a guiding mechanism in the existing equipment, the bushing is easily offset during the pressing process, resulting in the workpiece and the bushing being non-concentric or the installation position not corresponding. In addition, during the operation of the existing equipment, both hands enter the pressing area, and there is a risk of mechanical pinching. For this reason, we propose a semi-automatic pressing device for damper assemblies to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a semi-automatic pressing device for a damper assembly to solve the problems raised in the above background technology.

[0007] Among them, a transmission rod is movably inserted inside the stamping table, a rotating disk is installed at one end of the transmission rod, and a reset guide rod is installed on the rotating disk for auxiliary correction during the bushing feeding process. When the damper assembly needs to be pressed with the bushing, the bushing can be transported to both sides of the limit table with the help of the vibration disk. With the action of the stamping table, the bushing can be pushed to both sides of the limit table, and the operator can clamp the connecting ring of the damper assembly inside the limit table. With the help of the stamping table, the bushing can be clamped inside the connecting ring, which can effectively improve the installation efficiency of the damper assembly.

[0009] A straight groove is provided inside the limiting pressure rod, and a limiting slider is movably provided inside the straight groove. A locking ball is fixedly connected to the limiting slider. The feed ring cooperates with the locking ball to limit the bushing. Through the coordinated action of the elastic feed ring of the limiting pressure rod and the locking ball of the limiting slider, surface impurities can be scraped off and the position can be corrected in real time during the pushing process of the bushing.

The guide shafts are arc-shaped and elastic, and one end of the guide shaft is against the inner side of the push shaft.

The guide shaft is embedded in the recessed part of the inner wall of the bushing and the pushing angle is dynamically adjusted in combination with the reset guide rod of the rotating disk to ensure that the bushing pressing angle is uniform, thereby providing a standardized interface for subsequent assembly, reducing the rework rate and improving the overall assembly efficiency.

[0014] Preferably, the movable card at the bottom of the transmission track is provided with a storage baffle, and the storage baffle is in a "J" shape. The storage baffle is used for auxiliary storage of the bushing to ensure the processing accuracy of the equipment.

[0016] Preferably, a plurality of snap-in grooves are provided at the bottom of the support seat, and rubber pads are provided inside the snap-in grooves for buffering and shock absorption. The rubber pads of the push shaft, the magnetic buffer plates of the transmission track and the rubber pads of the support seat form a multi-stage buffer system, which not only reduces the push wear of the bushing, but also reduces the vibration of the equipment, thereby ensuring a smooth pressing process.

[0020] 3. The present invention uses the synergistic effect of the elastic feed ring of the limit pressure rod and the clamping ball of the limit slider to scrape off surface impurities and correct the position in real time during the bushing pushing process.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 7 The present invention provides a technical solution: a semi-automatic pressing device for a damper assembly, comprising:

[0033] A workbench, on the top of which a support seat 1 and a pair of vibration plates 4 are installed, a limit table 2 and a pair of punching tables 3 are installed on the top of the support seat 1, the punching tables 3 are arranged on both sides of the limit table 2 and correspond to the vibration plates 4, a limit block 21 is installed on the top of the limit table 2, a card slot is opened inside the limit block 21, and docking rings 22 are installed at both ends of the limit block 21, and a transmission track 41 is installed on the vibration plate 4, and one end of the transmission track 41 corresponds to the position of the docking ring 22;

[0034] Among them, a transmission rod 32 is movably inserted inside the stamping table 3, and a rotating disk 33 is installed at one end of the transmission rod 32. A reset guide rod 35 is installed on the rotating disk 33 for auxiliary correction during the bushing feeding process. When the damper assembly needs to be pressed with the bushing, the bushing can be transported to both sides of the limit table 2 with the help of the vibration disk 4. With the action of the stamping table 3, the bushing can be pushed to both sides of the limit table 2, and the operator can clamp the connecting ring of the damper assembly inside the limit table 2, and with the help of the stamping table 3, the bushing can be clamped inside the connecting ring, which can effectively improve the installation efficiency of the damper assembly.

[0035] like Figure 2 and Figure 3 As shown, in order to reduce the situation that the bushing is tilted and offset during the feeding and pressing process, multiple fixed shafts are installed on the docking ring 22, and the fixed shaft sleeve is provided with a limit pressure rod 23, the limit pressure rod 23 is rectangular, and a feed ring 25 is provided at one end of the limit pressure rod 23. The feed ring 25 is installed on the outside of the limit pressure rod 23. The feed ring 25 is conical and the inner ring is elastic. With the help of the elastic inner ring of the feed ring 25, the outer wall of the bushing can be cleaned, and the oil and debris remaining on the surface can be scraped off, so as to reduce the accidental deviation of the bushing during the pressing process;

[0036] A straight groove is provided inside the limiting pressure rod 23, and a limiting slider 24 is movably provided inside the straight groove. A locking ball is fixedly connected to the limiting slider 24. The feed ring 25 cooperates with the locking ball to limit the bushing. As the bushing moves between the limiting pressure rod 23 under the action of the push shaft 341, the bushing can be clamped in the elastic inner ring of the feed ring 25 and the locking ball to ensure that it is in a concentric state with the docking ring 22, which can ensure that the bushing is in a stable position during the subsequent feeding process, play a role in auxiliary calibration, and reduce the wear and tear in the subsequent pressing process that affects the processing quality of the equipment.

[0037] like Figure 4 and Figure 5 As shown, in order to reduce the tilting and offset of the connecting ring on the damper assembly during the manual loading process of the operator, a piston assembly 27 is installed on the outside of the limit platform 2, and the piston assembly 27 includes an air pipe and a sealing sleeve, and the air pipe is installed on the outside of the limit platform 2. A hollow cavity is provided inside the limit platform 2, and a transmission top block 28 is inserted inside the hollow cavity. The top of the transmission top block 28 is in an inwardly concave arc shape, and a reset shaft 26 is movably provided at the open end of the limit block 21. A connecting plate 261 is installed between the reset shaft 26 and the sealing sleeve. As the damper assembly abuts against the top of the reset shaft 26, the connecting plate 261 can cooperate with the sealing sleeve to push the sealing sleeve to move, thereby changing the air pressure inside the hollow cavity, and the position of the transmission top block 28 can be adjusted to abut against the bottom of the connecting ring to play a role of auxiliary support, thereby reducing the offset during manual loading.

[0038] like Figure 4 and Figure 5 As shown, a limit card plate 29 is movably provided on the inner wall of the open end of the limit block 21. The edge of the limit card plate 29 is stepped, which is used to assist in supporting the limit of damper assemblies of different sizes and control the pushing position of the reset shaft 26. The damper assemblies of different models can be clamped between the limit card plates 29 and can be limited to different positions. Dampers of different signals can push the position of the reset shaft 26 and control the ejection position of the transmission top block 28, so that the connecting ring position of the damper assembly and the docking ring 22 maintain a relatively concentric position, reduce the tilting wear during the installation process, and ensure the processing quality of the equipment.

[0039] like Figure 6 As shown, the position of the push shaft 341 needs to be adjusted before installation, a fixed cylinder 31 is installed on the stamping table 3, a transmission plug rod 32 is installed on the output end of the fixed cylinder 31, the transmission plug rod 32 is concentrically arranged with the docking ring 22, a rotating disk 33 is rotatably provided on the transmission plug rod 32, a reset guide rod 35 is installed on the rotating disk 33, a plurality of limit blocks 34 are movably provided on the rotating disk 33, a plurality of push shafts 341 are installed on the limit blocks 34, the push shaft 341 is arc-shaped and a rubber pad is installed at one end, the push shaft 341 can be against the edge of the bushing, and the rubber pad can play a buffering role, reducing the wear of the bushing edge during the pushing process or the deviation during the movement that affects the installation.

[0040] It should also be noted that the snap-in ball at the bottom of the push shaft 341 and the limit slider 24 can provide auxiliary support for the bushing, thereby ensuring the stability of the feeding, and finally allowing the bushing to enter the connecting ring on the damper assembly along the docking ring 22, thereby ensuring the pressing accuracy of the equipment.

[0041] like Figure 6 As shown, in order to calibrate the installation position of the bushing, a connecting disk 36 is installed at one end of the reset guide rod 35, and a plurality of guide shafts 37 are installed on the inner wall of the connecting disk 36. The guide shafts 37 are arc-shaped and elastic, and one end of the guide shaft 37 is against the inner side of the push shaft 341. The guide shaft 37 can be against the recessed part of the inner wall of the bushing to calibrate the position of the bushing. When the reset guide rod 35 is fed, the guide shaft 37 can be clamped in the recessed part of the inner wall of the bushing, and the position of the bushing can be adjusted during the feeding process, so as to ensure that the angle of the pressed bushing remains consistent, which is convenient for subsequent assembly and connection.

[0042] like Figure 7 As shown, a storage baffle 42 is movably provided at the bottom of the transmission track 41 . The storage baffle 42 is in a “J” shape. The storage baffle 42 is used for auxiliary storage of the bushing. The bushing can be clamped inside the arc-shaped end of the storage baffle 42 .

[0043] like Figure 7 As shown, in order to ensure the stability of feeding and reduce jamming, a fixing groove is opened on the storage baffle 42, and a buffer sheet 43 is installed inside the fixing groove. Multiple metal shafts are installed at both ends of the buffer sheet 43, and the metal shafts are installed inside the fixing groove. The buffer sheet 43 is made of elastic material and has multiple magnetic blocks inside. The bushing can be clamped into the inside of the storage baffle 42. With the help of the magnetic blocks, the bushing can be clamped on the buffer sheet 43, so that the positions of the bushing and the feed ring 25 can correspond, thereby reducing jamming during the feeding process.

[0044] like Figure 1 As shown, a plurality of snap-in grooves are provided at the bottom of the support base 1, and rubber pads are provided inside the snap-in grooves for buffering and shock absorption to reduce vibration generated by the equipment during the pressing process.

[0045] Working principle: first, when the bushing of the damper assembly needs to be pressed, the bushing can be transported to both sides of the limit platform 2 with the help of the vibration plate 4, and the bushing can be pushed to both sides of the limit platform 2 with the help of the punching table 3, and the operator can clamp the connecting ring of the damper assembly inside the limit platform 2, and the bushing can be clamped inside the connecting ring with the help of the punching table 3, which can effectively improve the installation efficiency of the damper assembly, and when the damper assembly is clamped inside the limit block 21, the operator can place one end of the damper assembly against the top of the reset shaft 26, and the damper assembly has different sizes and models, and can be clamped at different positions on the limit clamping plate 29, thereby pushing the piston assembly 27, and under the action of air pressure changes, the transmission top block 28 can be pushed to move, thereby fine-tuning the position of the connecting ring on the damper assembly, reducing the offset during the subsequent bushing pressing process;

[0046] Then, under the action of the vibration plate 4, the bushing can be moved along the transmission track 41, and the bushing can be clamped into the inside of the storage baffle 42. With the help of the magnetic block, the bushing can be clamped on the buffer plate 43, so that the positions of the bushing and the feed ring 25 can correspond to each other, reducing the jamming during the feeding process. At this time, the punching table 3 starts to operate, which can drive the transmission plug rod 32 to move, and can adjust the position of the rotating disk 33 and the limit block 34, so as to facilitate the subsequent calibration of the bushing. When resetting the guide rod 35 to feed, the guide shaft 37 can be clamped in The concave part of the inner wall of the bushing can adjust the position of the bushing during the feeding process, which can ensure that the angle of the pressed bushing remains consistent, which is convenient for subsequent assembly and connection. In addition, during the feeding process, the bushing can be pushed along the feed ring 25, and the outer wall of the bushing can rub against the feed ring 25, which can scrape off the excess oil and debris on its surface. The two ends of the bushing are respectively connected to the elastic inner ring of the feed ring 25 and the clamping ball at the bottom of the limit slider 24, which can keep the bushing and the docking ring 22 in a concentric position, which can reduce the occurrence of bumps during the pressing process.

[0047] Finally, when the pushing shaft 341 is against one end of the bushing, the bushing can be pushed into the inside of the connecting ring, the damper assembly can be installed, and the operator can remove the damper assembly. Compared with traditional manual pressing equipment, it can not only improve processing efficiency, but also avoid the safety hazards of manual adjustment and calibration.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
