Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a ring riveting device for closing the mouth of a shock absorber. Background Technique

[0002] During the driving of an automobile, the unevenness of the road surface will cause the wheels to vibrate frequently. If not controlled, these vibrations will be transmitted to the vehicle body through the suspension, which will not only seriously affect the comfort of the passengers, but also may lead to a decline in the vehicle's handling performance and increase the driving risk. Shock absorbers are often needed to cooperate. The shock absorber attenuates the vibration of the spring during the rebound and compression processes, so that the wheels are always closely attached to the road surface, ensuring the smoothness and safety of the vehicle driving.

[0003] For a shock absorber, its closing part, as a key area for shock absorber sealing and connection, must have high strength, high sealing performance and good structural stability. If the sealing at the closing part is not tight, hydraulic oil leakage or gas escape will cause the shock absorber to fail. A ring riveting device is often used to close the mouth of the shock absorber. The ring riveting device can form a tight sealing structure by performing annular extrusion riveting on the end of the shock absorber, effectively preventing the leakage of internal media and ensuring the stable operation of the shock absorber.

[0004] Chinese Utility Model Patent Publication No.: CN219837735U, discloses: a rapid riveting device for the top rubber bolt of a shock absorber. When the screw body falls from the material bucket, the first pneumatic push rod drives the baffle to retract. At this time, the screw body enters the receiving box. At this time, the second pneumatic push rod pushes the receiving box, and drives the screw body to correspond to the riveting head after being stressed. After the punching cylinder is started, it pushes the piston column and the riveting head to descend. During the movement, the riveting head pushes the screw body inside the receiving box, and the stressed screw body squeezes the clamping blocks and the springs. Then the two springs respectively push the two clamping blocks to move away from each other. However, although this rapid riveting device for the top rubber bolt of a shock absorber can achieve automatic feeding and automatic installation, it is not convenient to achieve rapid limiting of the shock absorber, resulting in the displacement of the shock absorber during the processing, and it cannot be fixed according to shock absorbers of different sizes. During riveting, it is not convenient to adjust the position of the "n"-shaped placement rack according to the ring riveting requirements, resulting in poor practicability. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a ring riveting device for closing the mouth of a shock absorber, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by the present utility model is as follows: A ring riveting device for the necking of a shock absorber, comprising a workbench, a ring riveting cylinder, a ring riveting end head, a shock absorber limiting component, and a rivet adjusting component. One end of the workbench close to the ring riveting cylinder is fixedly installed with a support frame having an "L"-shaped cross-section structure. One end of the support frame close to the workbench is fixedly installed with a limiting frame. One end of the limiting frame away from the workbench is provided with a rivet adjusting component, and one end of the rivet adjusting component away from the limiting frame extends to directly below the ring riveting end head;

[0007] The shock absorber limiting component includes a bottom plate. One end of the bottom plate away from the workbench is fixedly installed with a slide rail. One end of the bottom plate close to the slide rail is penetrated and provided with a plurality of equally spaced positioning holes one for positioning. One end of the slide rail away from the bottom plate is slidably connected with a slide seat. One end of the slide seat away from the bottom plate is fixedly installed with a limiting frame one having a "C"-shaped cross-section structure. The slide seat is penetrated from top to bottom with a positioning hole two adapted to the positioning hole one;

[0008] The rivet adjusting component includes two limiting frames two designed in a cross shape and two sliders correspondingly assembled and connected with the two limiting frames two. One end of the two sliders away from the limiting frames two is fixedly assembled with an "n"-shaped placement rack.

[0009] Preferably, one surface of the bottom plate close to the slide rail and one end close to the center line of the slide rail are provided with a chute one for slidably connecting with the slide seat. The bottom plate and the slide seat are threadedly connected with a positioning bolt one through the positioning hole two and the positioning hole one for positioning.

[0010] Through the above technical solution, when installing the shock absorber limiting component, first place the slide seat on the chute one of the bottom plate so that the slide seat can slide along the chute one to adjust the position. According to the size of the shock absorber, after adjusting the slide seat to a suitable position, align the positioning hole two with the corresponding positioning hole one, and then pass the positioning bolt one through the positioning hole two and the positioning hole one and tighten it, which can not only prevent it from shifting during processing, but also fix it according to shock absorbers of different sizes.

[0011] Preferably, there are two identical slide seats, limiting frames one, positioning holes two, and positioning bolts one. The two slide seats, limiting frames one, positioning holes two, and positioning bolts one are symmetrically distributed about the center line of the bottom plate.

[0012] Through the above technical solution, the symmetrically distributed structure enables the shock absorber to receive uniform limiting force, avoiding the shock absorber from tilting or shifting due to uneven force. The two groups of limiting components work together to stably limit the shock absorber from both sides and improve the stability during fixation.

[0013] Preferably, along the length direction of the second limiting frame, a second sliding groove is formed through one end of the second limiting frame close to the limiting bracket. The second sliding groove is slidably connected with the sliding block, and the sliding block is integrally assembled with the "n"-shaped placement rack.

[0014] Through the above technical solution, when installing the rivet adjusting assembly, the sliding block is inserted into the second sliding groove of the second limiting frame. During use, according to the requirements of ring riveting, the "n"-shaped placement rack can be manually pushed to drive the sliding block to slide in the second sliding groove, so as to adjust the position of the "n"-shaped placement rack, which is convenient for quickly adjusting the "n"-shaped placement rack to a suitable position according to rivets of different sizes and shapes and the ring riveting position.

[0015] Preferably, a plurality of third positioning holes are formed through one end of the second limiting frame at equal intervals, and a second positioning bolt is threadedly connected to the second limiting frame from top to bottom and penetrates through the second limiting frame and the sliding block.

[0016] Through the above technical solution, after adjusting to a suitable position, the cooperation between the third positioning hole and the second positioning bolt can be used to lock the two, which can avoid the deviation of the positions of the two after the adjustment is completed, thus affecting the normal use.

[0017] Preferably, a limiting groove is formed at one end of the "n"-shaped placement rack away from the limiting bracket. A placement plate is arranged on the "n"-shaped placement rack through the limiting groove, and a through groove is formed through the placement plate from top to bottom.

[0018] Through the above technical solution, the rivet is placed on the placement plate, and the rivet passes through the through groove. According to the size of the rivet and the requirements of ring riveting, the placement plate can be quickly installed through the limiting groove, which is convenient for connecting the placement plate with the "n"-shaped placement rack.

[0019] Preferably, a protective frame fixedly installed with the support frame is fixedly installed on the outer edge of the ring riveting cylinder. A limiting plate is fixedly installed at one end of the protective frame away from the workbench. A control box and a control switch are fixedly installed at one end of the limiting bracket away from the center line. A slot is formed at one end of the limiting bracket close to the shock absorber limiting assembly, and a plug fixedly installed with the shock absorber limiting assembly is inserted into the inner surface of the slot.

[0020] Through the above technical solution, the ring riveting cylinder and the ring riveting end are protected by the protective frame and the limiting plate, which can prevent debris, splashes, etc. generated during the ring riveting process from injuring the operator or damaging the equipment. And the cooperation between the slot and the plug can facilitate the installation of the shock absorber limiting assembly above the workbench.

[0021] Compared with the prior art, the present invention provides a ring riveting device for shock absorber closing, which has the following beneficial effects:

[0022] 1. The shock absorber uses a ring rivet device to close the end. When installing the shock absorber limit assembly, first place the slide on the slide groove 1 of the base plate so that the slide can slide along the slide groove 1 to adjust its position. According to the size of the shock absorber, after adjusting the slide to the appropriate position, align the positioning hole 2 with the corresponding positioning hole 1, and then pass the positioning bolt 1 through the positioning hole 2 and tighten it together with the positioning hole 1. This can prevent displacement during processing and can also be fixed according to shock absorbers of different sizes.

[0023] 2. The shock absorber uses a ring rivet device to close the end. When installing the rivet adjustment component, insert the slider into the second slide groove of the limit frame. During use, according to the ring rivet requirements, the "N"-shaped placement frame can be manually pushed to drive the slider to slide in the second slide groove to adjust the position of the "N"-shaped placement frame. It is convenient to quickly adjust the "N"-shaped placement frame to the appropriate position according to rivets of different sizes and shapes and ring rivet positions. Combined with the upper limit slot, it is convenient to quickly place the placement plate and provide a placement platform for rivets, thereby improving the practicality of the overall device.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: As Figures 1-6 shown, a ring riveting device for shock absorber closing mouths provided by the present invention includes a workbench 1, a ring riveting cylinder 5, a ring riveting end 6, a shock absorber limit assembly 12 and a rivet adjustment assembly 13. A support frame 2 with an "L"-shaped cross-section is fixedly installed at one end of the workbench 1 close to the ring riveting cylinder 5. A limit frame 7 is fixedly installed at one end of the support frame 2 close to the workbench 1. A rivet adjustment assembly 13 is arranged at one end of the limit frame 7 away from the workbench 1. One end of the rivet adjustment assembly 13 away from the limit frame 7 extends to directly below the ring riveting end 6;

[0033] The shock absorber limit assembly 12 includes a bottom plate 1201. A slide rail 1202 is fixedly installed at one end of the bottom plate 1201 away from the workbench 1. A plurality of first positioning holes 1203 for positioning and distributed at equal intervals are formed through one end of the bottom plate 1201 close to the slide rail 1202. A slide seat 1205 is slidably connected to one end of the slide rail 1202 away from the bottom plate 1201. A first limit frame 1206 with a "C"-shaped cross-section is fixedly installed at one end of the slide seat 1205 away from the bottom plate 1201. A second positioning hole 1207 adapted to the first positioning hole 1203 is formed through the slide seat 1205 from top to bottom;

[0034] The rivet adjusting assembly 13 includes two limiting frames two 1301 with a cross-shaped structure design and two sliders 1305 correspondingly assembled and connected to the two limiting frames two 1301.

[0035] Specifically, on one side of the bottom plate 1201 close to the slide rail 1202 and at one end close to the center line of the slide rail 1202, a first chute 1204 for sliding connection with the slide seat 1205 is opened. The bottom plate 1201 and the slide seat 1205 are threadedly connected through a second positioning hole 1207 and a first positioning hole 1203 with a positioning bolt one 1208 for positioning. The advantage is that when installing the shock absorber limiting assembly 12, first place the slide seat 1205 on the first chute 1204 of the bottom plate 1201, so that the slide seat 1205 can slide and adjust its position along the first chute 1204. According to the size of the shock absorber, after adjusting the slide seat 1205 to a suitable position, align the second positioning hole 1207 with the corresponding first positioning hole 1203, and then pass the positioning bolt one 1208 through the second positioning hole 1207 and the first positioning hole 1203 and tighten it, which can not only prevent it from shifting during processing, but also fix it according to different sizes of shock absorbers.

[0036] Specifically, there are two identical slide seats 1205, limiting frames one 1206, second positioning holes 1207 and positioning bolts one 1208. The two slide seats 1205, limiting frames one 1206, second positioning holes 1207 and positioning bolts one 1208 are symmetrically distributed about the center line of the bottom plate 1201. The advantage is that the symmetrically distributed structure enables the shock absorber to receive uniform limiting force, avoiding the shock absorber from tilting or shifting due to uneven force. The two groups of limiting components work together to stably limit the shock absorber from both sides and improve the stability during fixation.

[0037] Specifically, along the length direction of the limiting frame two 1301, a second chute 1302 is penetrated and opened at one end of the limiting frame two 1301 close to the limiting frame 7. The second chute 1302 is in sliding connection with the slider 1305. The slider 1305 and the "n"-shaped placement rack 1306 are integrally assembled structures. The advantage is that when installing the rivet adjusting assembly 13, insert the slider 1305 into the second chute 1302 of the limiting frame two 1301. During use, according to the need for ring riveting, manually push the "n"-shaped placement rack 1306 to drive the slider 1305 to slide in the second chute 1302 and adjust the position of the "n"-shaped placement rack 1306, which is convenient to quickly adjust the "n"-shaped placement rack 1306 to a suitable position according to different sizes, shapes of rivets and ring riveting positions, and can improve its practicability.

[0038] Embodiment 2: As Figures 2-6 shown, as an improvement to the previous embodiment.

[0039] Specifically, a plurality of positioning holes three 1303 are formed at one end of the limiting frame two 1301 in an equally spaced manner. A positioning bolt two 1304 is threadedly connected to the limiting frame two 1301 from top to bottom and penetrates through the limiting frame two 1301 and the slider 1305. The advantage is that after adjusting to a suitable position, the cooperation between the positioning hole three 1303 and the positioning bolt two 1304 can be used to lock the two, avoiding the deviation of their positions after the adjustment, thus affecting the normal use.

[0040] Specifically, a limiting groove 1307 is formed at one end of the "n"-shaped placing rack 1306 away from the limiting rack 7. A placing plate 1308 is arranged on the "n"-shaped placing rack 1306 through the limiting groove 1307. A through groove 1309 is formed in the placing plate 1308 from top to bottom. The advantage is that by placing the rivets on the placing plate 1308 and making the rivets pass through the through groove 1309, according to the size of the rivets and the requirements of ring riveting, the placing plate 1308 can be quickly installed through the limiting groove 1307, facilitating the connection between the placing plate 1308 and the "n"-shaped placing rack 1306.

[0041] Specifically, a protective frame 3 fixedly installed with the support frame 2 is fixedly installed on the outer edge of the ring riveting cylinder 5. A limiting plate 4 is fixedly installed at one end of the protective frame 3 away from the workbench 1. A control box 8 and a control switch 9 are fixedly installed at one end of the limiting rack 7 away from the center line. A slot 10 is formed at one end of the limiting rack 7 close to the shock absorber limiting component 12. An insertion block 11 fixedly installed with the shock absorber limiting component 12 is inserted and installed on the inner surface of the slot 10. The advantage is that the ring riveting cylinder 5 and the ring riveting end 6 are protected by the protective frame 3 and the limiting plate 4, preventing debris, splashes, etc. generated during the ring riveting process from injuring the operator or damaging the equipment. And the cooperation between the slot 10 and the insertion block 11 can facilitate the installation of the shock absorber limiting component 12 above the workbench 1.

[0042] Working principle: When in use, when installing the shock absorber limit component 12, first place the slide block 1205 on the first chute 1204 of the bottom plate 1201, so that the slide block 1205 can slide and adjust its position along the first chute 1204. According to the size of the shock absorber, after adjusting the slide block 1205 to the appropriate position, align the second positioning hole 1207 with the corresponding first positioning hole 1203, and then pass the first positioning bolt 1208 through the second positioning hole 1207 and the first positioning hole 1203 and tighten it. This can not only prevent displacement during processing, but also fix it according to shock absorbers of different sizes. The symmetrically distributed structure enables the shock absorber to receive uniform limiting force, avoiding tilting or offset of the shock absorber caused by uneven force. The two limit components work together to stably limit the shock absorber from both sides, improving the stability during fixation. When installing the rivet adjustment component 13, insert the slider 1305 into the second chute 1302 of the second limit frame 1301. During use, according to the requirements of ring riveting, manually push the "n"-shaped placement rack 1306 to drive the slider 1305 to slide in the second chute 1302, adjusting the position of the "n"-shaped placement rack 1306, which is convenient for quickly adjusting the "n"-shaped placement rack 1306 to the appropriate position according to rivets of different sizes and shapes and the ring riveting position, improving its practicability. After adjusting to the appropriate position, through the cooperation between the third positioning hole 1303 and the second positioning bolt 1304, the two can be locked, avoiding the offset of their positions after adjustment, thus affecting normal use. Place the rivet on the placement plate 1308, so that the rivet passes through the through slot 1309. According to the size of the rivet and the requirements of ring riveting, it is convenient to quickly install the placement plate 1308 through the limit slot 1307, facilitating the connection between the placement plate 1308 and the "n"-shaped placement rack 1306. Protect the ring riveting cylinder 5 and the ring riveting end 6 through the protective frame 3 and the limit plate 4, preventing debris, splashes, etc. generated during the ring riveting process from harming the operator or damaging the equipment. And the cooperation between the slot 10 and the plug 11 facilitates the installation of the shock absorber limit component 12 above the workbench 1.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
