Description

Technical Field

[0001] The invention belongs to the technical field of shock absorber welding and relates to a welding device for accessories used in shock absorber production. Background Art

[0002] As the most popular and convenient means of modern transportation, vehicles are crucial for their ride quality and handling stability. To enhance these two aspects, shock absorbers are an essential component of the vehicle's suspension system, effectively reducing resonance and dampening vibration. Exquisite craftsmanship plays a central role in shock absorber manufacturing, directly determining their performance and reliability. During the processing of shock absorber parts, the protective cover and connecting lugs must be welded together.

[0003] Currently, the common method of connecting the protective cover and the lifting lug of the shock absorber is to use a seam welder for welding. This process involves putting the protective cover on a fixed mold, then placing the lifting lug on top of the protective cover, and then using a cylinder to push the seam welding disc into contact with the protective cover to start the welding process. However, if the cylinder stroke is not properly controlled, if the seam welding disc continues to apply force after contacting the protective cover, it is very likely to squeeze and force the protective cover to deform, causing damage to the protective cover, thereby affecting the product's qualification rate. In addition, due to the variety of shock absorber specifications, the corresponding protective cover diameters are also different. When using a fixed-size mold to fix protective covers of different specifications, the mold must be frequently replaced, which is not only cumbersome to operate, but also significantly reduces production efficiency.

[0032] like Figure 4As shown, the connection structure includes a sliding shaft 61, an elastic member 62 and a connecting block 63. The sliding shaft 61 is slidably connected to the sliding frame 51, and the sliding shaft 61 can slide left and right along the sliding frame 51. An elastic member 62 is connected between the sliding frame 51 and the sliding shaft 61. The elastic member 62 is a buffer spring. The two sliding shafts 61 are connected to a connecting block 63 on the side close to each other.

[0033] like Figure 3 As shown, the driving mechanism includes a cylinder 52 and a connecting rod 53. The cylinder 52 is installed in the middle position of the upper part of the side panel 3. The telescopic rod of the cylinder 52 is hingedly connected to the connecting blocks 63 on both sides with a connecting rod 53. When the telescopic rod of the cylinder 52 is extended or retracted, it can drive the connecting blocks 63 on both sides to move closer to or away from each other through the connecting rod 53.

[0034] like Figure 5 and Figure 6 As shown, the placement mechanism includes a guide frame 71, a sliding plate 72, a placement shaft 73 and a supporting plate 74. The guide frame 71 is connected to the middle of the top of the base plate 2. The sliding plate 72 is slidably connected to the guide frame 71. The placement shaft 73 is rotatably connected to the middle of the top of the sliding plate 72. The placement shaft 73 passes through the guide frame 71 and can slide on the guide frame 71. The protective cover can be sleeved on the placement shaft 73. A threaded groove is provided at the lower part of the placement shaft 73. The lower part of the placement shaft 73 is threadedly connected to the supporting plate 74 through the threaded groove. The supporting plate 74 can rotate and move up and down through the threaded groove to resist the protective cover and support the protective cover.

[0035] like Figure 5 and Figure 6 As shown, the protective cover fixing mechanism includes a fixed airbag 91, an air pump 92 and an air pipe 93. The air pump 92 is installed on the side panel 3, and the air pipe 93 is installed at the air outlet end of the air pump 92. The fixed airbag 91 is installed in the middle of the placement shaft 73, and an air guide channel 94 is opened in the middle of the placement shaft 73. The air pipe 93 is connected to the air guide channel 94. A plurality of air injection holes 95 are evenly spaced on the placement shaft 73. The outer side of the air injection hole 95 is located in the fixed airbag 91, and the inner side of the air injection hole 95 is connected to the air guide channel 94, so that the air pump 92 can inject air into the fixed airbag 91 through the air pipe 93, the air guide channel 94 and the air injection hole 95.

[0036] When it is necessary to weld the accessories of the shock absorber, this welding device can be used. When in use, first pull the placement shaft 73 to slide forward so that the placement shaft 73 is no longer located between the two seam welding plates 41, and then the protective cover of the shock absorber is placed on the placement shaft 73. Before the sleeve is placed, the support plate 74 can be controlled to rotate according to the length of the protective cover, and the support plate 74 can be adjusted by moving up and down along the sliding shaft 61 through the thread. When placing, the support plate 74 can support the protective cover so that the top of the protective cover is flush with the position between the two seam welding plates 41, and then the ear cover of the shock absorber is placed on the protective cover. At the top, the air pump 92 is controlled to operate and inject air into the air guide channel 94 through the air delivery pipe 93. The gas in the air guide channel 94 can be injected into the fixed air bag 91 through the air injection hole 95, so that the fixed air bag 91 expands, thereby pressing against the inner wall of the protective cover and fixing the protective cover. Then, the placement shaft 73 is pushed to slide backward to drive the protective cover and the lifting ear to move between the seam welding discs 41 on both sides. Then, the seam welding machine 4 can be controlled to drive the seam welding disc 41 to rotate, and at the same time, the telescopic rod of the cylinder 52 is controlled to retract to drive the two connecting blocks 63 to approach each other through the two connecting rods 53. When the two connecting blocks 63 approach each other, they drive the two sliding The movable shafts 61 approach each other, and the sliding shaft 61 drives the sliding frame 51 to move through the elastic member 62 when moving, thereby driving the two seam welding plates 41 to approach each other. When the two seam welding plates 41 are moved to the contact position with the protective cover and the lifting ear, the seam welding plates 41 rotate to weld the welding position of the protective cover and the lifting ear, thereby completing the welding work of the shock absorber accessories. During welding, if the seam welding plates 41 have been in contact with the protective cover and the lifting ear, the seam welding plates 41 no longer move at this time. If the staff does not pay attention to closing the cylinder 52, then the sliding shaft 61 continues to move, which can make the elastic member 6 2 deformation, thereby buffering through the elastic member 1 62 to prevent the seam welding disc 41 from continuing to move and squeezing the protective sleeve, causing the protective sleeve to deform. In this way, the device can be used to weld the accessories of the shock absorber, and when the seam welding disc 41 is controlled to move, the elastic member 1 62 can be used for buffering to prevent the seam welding disc 41 from moving too long due to the uncontrolled movement stroke of the cylinder 52, thereby preventing the protective sleeve from being squeezed and deformed, thereby protecting the protective sleeve. After welding is completed, the telescopic rod of the control cylinder 52 is extended to drive the sliding frames 51 on both sides and the seam welding discs 41 on both sides to move away from each other through the connecting rod 1 53.

[0037] like Figure 8 and Figure 9As shown, it also includes a transmission mechanism, which includes a push rod 101, a piston rod 102, a cylinder body 103, a pressure block 104, a sleeve 105, a sliding rod 106, a connecting pipe 107 and an elastic member 108. The telescopic rod of the cylinder 52 is connected to the push rod 101, and the lower front part of the side plate 3 is connected to the cylinder body 103. The piston rod 102 is slidably connected in the cylinder body 103. The top of the piston rod 102 is connected to the pressure block 104. The pressure block 104 is located below the push rod 101 to make the push rod 101 move downward. It can squeeze the pressure block 104 downward, and the left and right sides of the lower front side of the side plate 3 are connected with sleeves 105. A sliding rod 106 is slidably connected inside the sleeve 105. The front side of the sliding rod 106 is connected to the sliding plate 72. A connecting pipe 107 is connected between the rear side of the sleeve 105 and the bottom of the cylinder body 103. The cylinder body 103, the connecting pipe 107 and the sleeve 105 are all filled with liquid. An elastic part 2 108 is connected between the piston rod 102 and the cylinder body 103, and the elastic part 2 108 is a return spring.

[0038] When the telescopic rod of the control cylinder 52 is extended, the cylinder 52 can drive the push rod 101 to move downward. When the push rod 101 moves downward, it can contact the pressure block 104 and squeeze the pressure block 104 to move downward. When the pressure block 104 moves downward, it drives the piston rod 102 to move downward. The elastic member 108 is stretched. When the piston rod 102 moves downward, it can squeeze the liquid in the cylinder body 103 and inject the liquid in the cylinder body 103 into the sleeve 105 through the connecting pipe 107, thereby squeezing the sliding rod 106 to move forward. When the sliding rod 106 moves forward, When the cylinder 52 telescopic rod is retracted, the push rod 101 is disengaged from the pressure block 104, and the piston rod 102 moves upward and resets under the action of the elastic member 108 to draw the liquid back into the cylinder body 103, and the sliding rod 106 is reset accordingly, thereby driving the sliding plate 72 to reset. This is repeated to achieve the effect of automatically driving the placement shaft 73 to move, which is more convenient to operate.

[0039] like Figure 10-12 As shown, it also includes a lifting ear fixing mechanism, which includes an outward expansion plate 111, a guide rod 112, a connecting ring 113 and a connecting rod 2 114. A plurality of sliding channels 115 are evenly spaced along the circumference on the upper part of the placement shaft 73. The sliding channels 115 are slidably connected with the guide rod 112, and the guide rod 112 is connected with the outward expansion plate 111. The upper part of the placement shaft 73 is slidably connected with a connecting ring 113, and the connecting ring 113 can slide up and down along the placement shaft 73. The connecting ring 113 and the outward expansion plate 111 are hingedly connected with a connecting rod 2 114.

[0040] When the air pump 92 injects air into the air guide channel 94, the gas in the air guide channel 94 will enter the sliding channel 115 and squeeze the guide rod 112, thereby driving the guide rod 112 to move outward. When the guide rod 112 moves, it can drive the outward expansion plate 111 to move. When the outward expansion plate 111 moves, it can support the ear of the shock absorber, thereby fixing the shock absorber ear. While the outward expansion plate 111 moves, it will also drive the connecting ring 113 to move upward through the connecting rod 2 114. In this way, the shock absorber ear can be supported by the outward expansion plate 111, and the shock absorber ear can be fixed to the protective cover of the shock absorber for easy welding.

[0041] like Figure 13 and Figure 14 As shown, a cooling mechanism is also included, which includes a connecting plate 121, a nozzle 122 and a collection frame 123. The collection frame 123 is slidably connected to the base frame 1, and a plurality of leakage holes are evenly spaced on the base plate 2. The top of the sliding frame 51 is connected to the connecting plate 121, and the nozzle 122 is installed on the upper part of the connecting plate 121.

[0042] like Figure 14 As shown, a separation net 131 is also included. The separation net 131 is provided on the upper inner portion of the collection frame 123 for separating water and impurities.

[0043] Before welding, the nozzle 122 can be connected to an external coolant pipe. After welding is completed, the coolant can be sprayed out through the nozzle 122 and sprayed on the welding position of the protective sleeve and the lifting ear to assist in cooling. The coolant will flow on the base plate 2 and flow into the collection frame 123 through the leakage hole. The coolant is collected by the collection frame 123, and the separation net 131 can separate the impurities mixed in the coolant from the coolant. In this way, after welding is completed, the welding position of the protective sleeve and the lifting ear can be assisted in cooling.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
