Description

Technical Field

[0001] This utility model belongs to the field of welding device protection technology, and in particular relates to a shock absorber dust cover welding device anti-splash protection structure. Background Technology

[0002] With the rapid development of the construction machinery industry, shock absorbers, as core vibration damping components, are widely used in the suspension systems of various heavy equipment. Their working environments are often characterized by high dust, high humidity, and strong impact. Dust covers, as key protective components of shock absorbers, are mainly used to prevent dust, moisture, and foreign objects from entering the piston rod and oil seal area, thus extending the service life of the shock absorber.

[0003] Currently, some manufacturers use a six-point welding device to fix the dust cover in a ring-shaped spot weld. However, during the spot welding process, the local high temperature can easily cause the metal material to melt and splash. The resulting splash particles not only adhere to the surface of the device, increasing cleaning and maintenance costs, but also pose a safety hazard of burning the skin of operators.

[0004] Therefore, there is a particular need for a splash-proof protection structure for the welding device of the shock absorber dust cover to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing six-point welding devices that lack spatter protection, leading to device contamination and personnel burn risks, this utility model provides a spatter protection structure for a shock absorber dust cover welding device.

[0006] This utility model is achieved through the following technical means: a splash protection structure for a welding device for a shock absorber dust cover, comprising a first protective shell, a second protective shell, an observation plate, a limiting cylinder, a connecting shell, a docking cylinder, and fixing bolts. The first protective shell is installed on one side of the second protective shell by multiple fixing bolts. The first and second protective shells together form a protective space. Observation plates are embedded and fixedly connected to the front of the first protective shell and the rear of the second protective shell. A limiting cylinder is fixedly connected between the two observation plates. Multiple through holes are evenly opened circumferentially on the outer wall of the limiting cylinder, and the through holes connect to the interior of the limiting cylinder. Multiple connecting shells are slidably arranged in a ring array at the front of the second protective shell. The connecting shells form a sealed sliding contact with the first protective shell. The number of connecting shells is the same as the number of through holes, and the opening of one end of the connecting shell extending into the interior of the first and second protective shells is directly opposite the corresponding through hole. A docking cylinder is slidably arranged inside the limiting cylinder. Multiple docking grooves are evenly opened circumferentially on the outer wall of the docking cylinder, and the docking grooves connect to the interior of the docking cylinder. The number of docking grooves is the same as the number of through holes, and the multiple docking grooves and multiple through holes are staggered front and back.

[0007] Furthermore, it also includes support seats, connecting ropes, telescopic rods, and return springs. Multiple evenly distributed support seats are fixed to the outside of the second protective shell. A connecting rope is fixed to the end of each connecting shell away from the limiting cylinder. The connecting rope passes through the corresponding support seat and forms a sliding fit with the support seat. Multiple telescopic rods arranged in a ring array are provided at the rear of the second protective shell. The fixed end and the movable end of the telescopic rod are connected to the second protective shell and the docking cylinder, respectively. The end of the connecting rope that is not connected to the connecting shell is fixedly connected to the rear of the docking cylinder. Multiple return springs arranged in a ring array are fixed between the second protective shell and the docking cylinder.

[0008] Furthermore, it also includes connecting pipes and valves. Connecting pipes are fixed to both sides of the protective shell, and each connecting pipe is equipped with a valve.

[0009] Furthermore, it also includes a limiting ring, which is fixed to the rear of the docking cylinder, with the front end face of the limiting ring contacting and engaging with the rear end face of the rear observation plate.

[0010] Furthermore, the width of the mating groove is equal to the diameter of the through hole.

[0011] Furthermore, the valve is a manually operated valve.

[0012] Beneficial effects: 1. By setting up protective shell one, protective shell two, limiting cylinder, connecting shell and butt joint cylinder, the welding head is only allowed to enter the working area through the through hole and butt joint groove during the welding process. The spatter is blocked by the inner wall of protective shell one and protective shell two and deposited in the protective space, effectively preventing the molten spatter from spreading outward, improving the safety of operation and the cleanliness of the six-point welding device.

[0013] 2. By setting up a support base, connecting rope, telescopic rod and return spring, the docking cylinder is automatically driven to move backward to align the docking groove with the through hole during the process of the welding head moving to contact the dust cover. After welding is completed, it automatically resets to cover the through hole. No manual intervention is required throughout the process, which improves the efficiency and consistency of operation.

[0014] 3. By setting up connecting pipes and valves, an external purification machine can be connected to actively extract the fumes generated in the protective space during the welding process, improve the working environment, and comply with occupational health and safety production standards.

[0020] Example: A splash protection structure for a welding device for a shock absorber dust cover, such as... Figures 1-4 As shown, the device includes a protective shell 1, a protective shell 2, an observation plate 3, a limiting cylinder 4, a connecting shell 6, a docking cylinder 7, a limiting ring 71, and fixing bolts 9. The protective shell 1 is fixed to the front of the protective shell 2 by four fixing bolts 9. The protective shell 1 and the protective shell 2 together form a protective space. Annular observation plates 3 are embedded and fixedly connected to the front of the protective shell 1 and the rear of the protective shell 2, facilitating real-time observation of the interior of the protective space by the operator. A limiting cylinder 4 is fixedly connected between the two observation plates 3. Six circular through holes 5 are evenly distributed around the outer wall of the limiting cylinder 4, connecting to the interior of the limiting cylinder 4. Six connecting shells 6 arranged in a circular array are slidably disposed at the front of the protective shell 2. The connecting shells 6 form a sealed sliding contact with the protective shell 1. The number of connecting shells 6 and through holes 5 is... The opening of the connecting shell 6 extending into the interior of the protective shell 1 and the protective shell 2 is aligned with the corresponding through hole 5. The limiting cylinder 4 has a sliding docking cylinder 7. The rear of the docking cylinder 7 is fixedly connected to a limiting ring 71. The front end of the limiting ring 71 contacts and engages with the rear end of the rear observation plate 3, thereby limiting the maximum sliding stroke of the docking cylinder 7, so that the docking cylinder 7 can only slide backward initially. The outer wall of the docking cylinder 7 is evenly provided with six docking grooves 8. The docking grooves 8 connect to the interior of the docking cylinder 7. The number of docking grooves 8 is the same as that of the through holes 5, and the six docking grooves 8 and the six through holes 5 are staggered. When the docking grooves 8 are staggered from the through holes 5, the docking cylinder 7 blocks the through holes 5 through the physical contact between its outer wall and the inner wall of the limiting cylinder 4. The width of the docking groove 8 is equal to the diameter of the through hole 5.

[0021] like Figures 2-4As shown, it also includes a support base 10, a connecting rope 11, a telescopic rod 12, and a return spring 13. Six evenly distributed support bases 10 are fixedly connected to the outside of the second protective shell 2. A connecting rope 11 is fixedly connected to the end of each connecting shell 6 away from the limiting cylinder 4. The connecting rope 11 passes through the corresponding support base 10 and forms a sliding fit with the support base 10. Six telescopic rods 12 arranged in a ring array are provided at the rear of the second protective shell 2. The fixed end and the movable end of the telescopic rod 12 are respectively connected to the second protective shell 2 and the docking cylinder 7. The end of the connecting rope 11 that is not connected to the connecting shell 6 is fixedly connected to the rear of the docking cylinder 7. Six return springs 13 arranged in a ring array are fixedly connected between the second protective shell 2 and the docking cylinder 7. Initially, the return springs 13 are in a compressed state.

[0022] like Figures 1-3 As shown, it also includes a connecting pipe 14 and a valve 15. The upper and lower sides of the protective shell 2 are respectively fixedly connected to the connecting pipe 14, and each connecting pipe 14 is equipped with a valve 15. The valve 15 is a manually operated valve.

[0023] In use, the second protective shell 2 is installed on the six-point welding device. The six welding heads of the six-point welding device are respectively connected to the six connecting shells 6, ensuring that the ends of the welding heads extend from one end of the connecting shell 6 and enter the protective space between the first protective shell 1 and the second protective shell 2. Then, the dust cover is inserted into the docking cylinder 7, so that the outer wall of the dust cover is tightly against the inner wall of the docking cylinder 7. Then, the six-point welding device is operated to move the six welding heads toward the center of the limiting cylinder 4. During the movement, the welding heads drive the connecting shells 6 to slide inward, causing the connecting rope 11 to gradually loosen. The return spring 13 gradually returns to its original state, pushing the docking cylinder 7 to slide backward. The telescopic rod 12 extends accordingly. When the welding head is about to enter the through hole 5, the connecting rope 11 has been fully loosened, and the return spring 13 has fully extended. After restoring the entire structure to its original state, push the docking cylinder 7 backward to the appropriate position so that the docking groove 8 is aligned with the through hole 5. Then, the welding head passes through the through hole 5 and the docking groove 8 to contact the outer wall of the dust cover for spot welding. During the welding process, the spatter generated by the molten metal is blocked by the inner walls of the protective shell 1 and the protective shell 2. The spatter is deposited inside the protective space, thereby preventing the spatter from contaminating the six-point welding device and burning personnel. After the welding is completed, operate the six-point welding device to move the six welding heads away from the limiting cylinder 4 and out of the through hole 5. The welding heads drive the connecting shell 6 to slide outward. When the connecting shell 6 slides, it pulls the docking cylinder 7 forward through the connecting rope 11. The return spring 13 is compressed accordingly, and the telescopic rod 12 is shortened accordingly. Finally, the dust cover with the spot weld completed is pulled out from the docking cylinder 7.

[0024] In addition, before spot welding, the suction pipe of the purifier can be connected to the connecting pipe 14, and then the valve 15 can be operated to open the connecting pipe 14. During the welding process, the purifier can be started to suck away the fumes generated in the protective space.
