Description

Technical Field

[0001] This invention relates to the field of automotive shock absorber processing technology, and in particular to a welding device for processing the outer cylinder of an automotive shock absorber. Background Technology

[0002] Shock absorbers are used to suppress the oscillations when the spring absorbs shock and rebounds, as well as the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the frame and body, thereby improving the ride comfort of the car. When driving over uneven roads, shock absorbers can be used to suppress the reciprocating and jumping motion of the spring itself. The outer cylinder of the automobile shock absorber is fixed and assembled by circumferential welding. In actual operation, clamps are needed to fix the outer cylinder of the shock absorber, and then the entire circumference is circumferentially welded by hand or welding robot along the joint.

[0003] However, the existing welding equipment for assembling the outer cylinder of the shock absorber uses two sets of clamps to fix the two sections of the outer cylinder of the shock absorber and to precisely fix the welding position of the outer cylinder. After the outer cylinder is fixed, the adjustment of the workpiece to be welded is cumbersome and difficult to operate. When circumferential welding the butt joint after fixing the workpiece, it is not easy to drive the workpiece to rotate at a uniform speed, and it is not easy to control the welding accuracy. Moreover, during the welding process, loading and unloading are all done manually, which seriously reduces the processing efficiency. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1 to 11 As shown, a welding device for processing the outer cylinder of an automotive shock absorber includes a first mounting frame 1. The first mounting frame 1 has a lifting assembly 2 inside. The top of the lifting assembly 2 is connected to a first mounting plate 3. The top of the first mounting plate 3 has a plurality of evenly distributed rollers 4. Each roller 4 has a first support 5 rotatably connected to both ends. Each first support 5 is fixedly connected to the top of the first mounting plate 3. The outer surface of each roller 4 has a V-shaped groove 6. The two ends of the first mounting plate 3 are respectively equipped with an outer cylinder feeding assembly 7 and an end cap feeding assembly 8. The inner top of the first mounting frame 1 is equipped with a guide clamping assembly 9. The guide clamping assembly 9 is equipped with a rotating assembly for driving the outer cylinder to rotate. The top of the first mounting frame 1 is equipped with a welding assembly 10. The side of the first mounting plate 3 is connected to a discharge assembly 11. During the process of the lifting component 2 driving the first mounting plate 3 to move upward, the unloading component 11 is located beside the first mounting plate 3. During the process of the lifting component 2 driving the first mounting plate 3 to move downward, the unloading component 11 is located below the guide clamping component 9, so as to facilitate the unloading of the welded outer cylinder.

[0022] As an optional implementation, the outer cylinder feeding assembly 7 includes: The second mounting bracket 12 has a storage box 13 fixed on the top of one side, a discharge port 14 on the bottom of one side of the storage box 13, and a pusher block 15 passing through the other side. The first cylinder 16 is fixedly mounted on the top of the second mounting bracket 12, and the telescopic rod of the first cylinder 16 is fixedly connected to the side of the pusher block 15 away from the discharge port 14. The third mounting bracket 17 has one end set at one end of the first mounting plate 3 and the other end fixedly provided with a fixing plate 18. The top of the third mounting bracket 17 is provided with an arc-shaped groove 19, one end of which is connected to the V-shaped groove 6. A leak-proof plate 20 is fixedly provided on one side of the third mounting bracket 17 and a connecting frame 21 is provided on the other side. One end of the connecting frame 21 is inclined upward and fixedly connected to the bottom of the discharge port 14. The second cylinder 22 is fixed on the fixed plate 18. The telescopic rod of the second cylinder 22 passes through the fixed plate 18 and is fixed with a pusher plate 23. A part of the pusher plate 23 is disposed in the arc-shaped groove 19.

[0023] like Figure 1 and Figure 2 As shown, in the initial stage, the pusher block 15 is positioned at the discharge port 14 to prevent the outer cylinder from falling. During operation, the first cylinder 16 drives the pusher block 15 to move, opening the discharge port 14 and allowing the outer cylinder to fall to the bottom of the storage box 13. The first cylinder 16 then resets, driving the pusher block 15 to push the outer cylinder from the discharge port 14 through the connecting frame 21 to the third mounting bracket 17. After being blocked by the anti-leakage plate 20, the outer cylinder falls stably into the arc-shaped groove 19. The second cylinder 22 then drives the pusher plate. 23 moves, the pusher plate 23 drives the outer cylinder to move, so that the outer cylinder moves through the arc groove 19 and the V-shaped groove 6 to the roller 4, thus completing the loading of the outer cylinder. At the same time, the second cylinder 22 resets after the outer cylinder and the end cover are clamped and assembled. It should be noted that there is a damping structure between the roller 4 and the first support 5 to avoid the sensitivity of the roller 4 rotation. The outer surface of the roller 4 is covered with a structure to increase friction, such as polyurethane material, to prevent the outer cylinder from moving and causing the welding position to shift.

[0024] As an optional implementation, the end cap feeding assembly 8 includes: The first support plate 24 is disposed on the side of the first mounting bracket 1; The third cylinder 25 is fixed on the first support plate 24, and the telescopic rod of the third cylinder 25 passes through the first support plate 24. The storage frame 26 has one side fixedly connected to the telescopic rod of the third cylinder 25, and the bottom of the other side is provided with an opening. The storage frame 26 is provided with a limiting through hole 27 on the side away from the first mounting plate 3. One end of the limiting through hole 27 is connected to the top of the storage frame 26, and the other end is bent and connected to the opening. The limiting through hole 27 is provided with a feeding component at the end of the opening. The first guide rod 28 is inserted through the first support plate 24, and one end of the first guide rod 28 is fixedly connected to the storage frame 26. The second support plate 29 is disposed at the end of the first mounting frame 1 away from the outer cylinder feeding assembly 7; An electric push rod 30 is fixed on the side of the second support plate 29 away from the first mounting bracket 1, and the telescopic rod of the electric push rod 30 passes through the second support plate 29. Mounting plate 31, a limiting cylinder 32 is fixedly provided in the middle of the side away from the second support plate 29, the telescopic rod of the electric push rod 30 passes through the mounting plate 31 and a stop block 33 is fixedly provided, the stop block 33 is adapted to be disposed inside the limiting cylinder 32, and at least one second guide rod 34 is fixedly provided on the mounting plate 31, the second guide rod 34 passes through the second support plate 29; The material ejection assembly is disposed between the mounting plate 31 and the second support plate 29, and the material ejection assembly is mounted on the telescopic rod of the electric push rod 30.

[0025] like Figure 1 and Figure 3 As shown, the end cap at the bottom of the storage frame 26 is located at the feeding assembly, and this end cap is restricted from moving by the weight of other end caps stacked together. When the outer cylinder is placed on the roller 4, the storage frame 26 is moved by the third cylinder 25, and the storage frame 26 moves the end cap, causing the end cap to move to a position coaxial with the outer cylinder. The electric push rod 30 moves the mounting plate 31 through the unloading assembly, and the mounting plate 31 moves the limiting cylinder 32, causing the limiting cylinder 32 to fit onto one end cap. At this time, the feeding assembly releases the obstruction of the end cap, and the third cylinder 25 resets, allowing the end cap to detach from the storage frame 26. After the end cap detaches from the storage frame 26, the feeding assembly resets and continues to block other end caps, avoiding... To prevent other end caps from falling off the opening, the electric push rod 30 continues to move, driving the end caps to clamp and assemble with the outer cylinder. After the end caps and outer cylinder are clamped and assembled, the second cylinder 22 begins to reset, and the electric push rod 30 continues to move. The two work synchronously until the electric push rod 30, in conjunction with the ejection assembly, drives the stop block 33 to move, causing the stop block 33 to push a part of the end cap out of the limiting cylinder 32. At this point, the electric push rod 30 stops moving, and the second cylinder 22 continues to reset, thereby allowing the assembled outer cylinder to move stably onto the roller 4. In conjunction with the damping structure of the roller 4 and the friction-increasing structure on the outer surface of the roller 4, the accuracy of the welding position of the outer cylinder is ensured.

[0026] As an optional implementation, the feeding assembly includes: The first mounting groove 35 is located at the bottom of the limiting through hole 27 near the opening, and an electromagnet 36 is embedded on the side of the first mounting groove 35 away from the opening. The material stop rod 37 has one end hinged to the top of the limiting through hole 27 near the opening and a torsion spring structure installed at the hinge. The other end is set in the first mounting groove 35. An iron block 38 is embedded on the side of the material stop rod 37 near the electromagnet 36, and the iron block 38 is adapted to fit the electromagnet 36.

[0027] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the electromagnet 36 is energized to generate magnetic attraction, which, together with the iron block 38, locks the baffle rod 37, preventing the end cap from moving out of the opening. When the electromagnet 36 is de-energized, it loses its magnetism, and the electromagnet 36 and iron block 38 no longer attract each other, releasing the baffle rod 37. At the same time, the limiting cylinder 32 restricts the end cap, allowing it to detach from the storage frame 26. The hinge of the baffle rod 37 has a torsion spring structure. Under the action of the torsion spring structure, after the first end cap detaches from the opening, the baffle rod 37 can quickly reset, allowing the electromagnet 36 and iron block 38 to work together to lock the baffle rod 37, preventing other end caps from falling off.

[0028] As an optional implementation, the unloading component includes: At least two second mounting slots 39 are evenly distributed on the outer wall of the telescopic rod of the electric push rod 30; At least two reset rods 40, one end of which is respectively hinged to the end of the second mounting groove 39 away from the second support plate 29. The length of each reset rod 40 is less than the length of the second mounting groove 39, and a torsion spring structure is installed at the hinge point of each reset rod 40 and the second mounting groove 39 so that the reset rod 40 pushes the mounting plate 31 to move under the action of the torsion spring structure. At least two reset blocks 41 are respectively disposed on both sides of the second support plate 29, and each reset block 41 is sleeved on the second guide rod 34 and fixedly connected.

[0029] like Figure 1 , Figure 3 and Figure 6As shown, the electric push rod 30 drives the reset rod 40 to move via the second mounting groove 39 on the telescopic rod. The reset rod 40, influenced by the torsion spring structure, adheres to the mounting plate 31 and drives the mounting plate 31 to move. The mounting plate 31 then drives the limiting cylinder 32 to move, thus completing the material handling and assembly of the end cap. During the unloading process, a reset block 41 abuts against the second support plate 29, preventing the second guide rod 34 from moving, thereby preventing the mounting plate 31 from moving. The telescopic rod of the electric push rod 30 continues to move, causing the telescopic rod to drive the stop block 33 to move within the limiting cylinder 32. Simultaneously, it compresses... The reset rod 40 flips into the second mounting groove 39 until the stop block 33 drives one part of the end cover to completely exit the limiting cylinder 32, thereby completing the unloading of the end cover. After unloading, the reset is performed. Due to the torsion spring structure, the reset rod 40 is stuck in the mounting plate 31, causing the mounting plate 31 to move together with the telescopic rod of the electric push rod 30 until another reset block 41 abuts against the second support plate 29, making the mounting plate 31 unable to move. The telescopic rod of the electric push rod 30 continues to reset, so that the reset rod 40 is disengaged from the interior of the mounting plate 31 and reset under the action of the torsion spring structure.

[0030] As an optional implementation, the lifting assembly 2 includes: The fourth mounting bracket 42 is disposed at the bottom of the first mounting plate 3; The fourth cylinder 43 is fixedly mounted on the inner bottom of the fourth mounting bracket 42, and the telescopic rod of the fourth cylinder 43 passes through the fourth mounting bracket 42 and is fixedly connected to the first mounting plate 3. At least one third guide rod 44 is inserted through the top of the fourth mounting bracket 42, and one end of the third guide rod 44 is fixedly connected to the first mounting plate 3.

[0031] like Figure 1 and Figure 7 As shown, the first mounting plate 3 is moved up and down by the fourth cylinder 43, the first mounting plate 3 moves up and down by the first support 5, and the first support 5 moves up and down by the roller 4, thereby completing the lifting and lowering of the outer cylinder.

[0032] As an optional implementation, the guiding clamping assembly 9 includes: A first motor 45 is fixedly mounted on the top of the first mounting bracket 1, and a first gear 46 is fixedly mounted on the output shaft of the first motor 45 through the top of the first mounting bracket 1. Two sliding plates 47 are slidably connected to the inner top of the first mounting bracket 1. A first rack 48 is fixedly provided on the bottom of the two sliding plates 47 on the side away from each other. Each first rack 48 meshes with the first gear 46. Two vertical plates 49 are fixedly connected at one end to one end of the slide plate 47, and a horizontal plate 50 is fixedly provided at the other end. Each horizontal plate 50 has four first inclined plates 51 fixedly provided at its top and bottom, and the rotating assembly is provided on all the first inclined plates 51.

[0033] As an optional implementation, the rotating assembly includes: Multiple rectangular through holes 52 are respectively disposed on the first inclined plate 51; Multiple sliders 53 are respectively inserted into the rectangular through hole 52; Multiple pulleys 54 are respectively arranged on the side of the first inclined plate 51 away from the vertical plate 49. Each pulley 54 has a second support 55 rotatably connected to both ends. The free end of each second support 55 is bent and fixedly connected to the corresponding slider 53. A second motor 56 is fixedly mounted on one of the second supports 55, and the output shaft of the second motor 56 is fixedly connected to one end of the corresponding pulley 54. Multiple fixing blocks 57 are respectively disposed on the side of the first inclined plate 51 away from the pulley 54, and each fixing block 57 is fixed at a position of the first inclined plate 51 away from the horizontal plate 50. Multiple fourth guide rods 58 are respectively mounted on the fixed block 57, and one end of each fourth guide rod 58 is fixedly connected to one side of the slider 53. Multiple springs 59 are respectively sleeved on the fourth guide rod 58, and the two ends of each spring 59 abut against the fixed block 57 and the slider 53 respectively.

[0034] like Figure 1 and Figure 8 As shown, when the assembled outer cylinder moves into the guide clamping assembly 9, the first motor 45 drives the first gear 46 to rotate, the first gear 46 drives the two first racks 48 to move, the two first racks 48 drive the two slide plates 47 to move, the two slide plates 47 drive the two vertical plates 49 to move, the two vertical plates 49 drive the two horizontal plates 50 to move closer to each other, the two horizontal plates 50 respectively drive the corresponding four first inclined plates 51 to move, each first inclined plate 51 respectively drives the corresponding second support 55 to move, each second support 55 drives the corresponding pulley 54 to move, so that the pulley 54 presses against the outer surface of the outer cylinder. By setting a rectangular through hole 52, slider 53, fixing block 57, fourth guide rod 58 and spring 59 on the first inclined plate 51, the pressing force of the pulley 54 on the outer cylinder is controlled, and the rotation speed of the outer cylinder is further controlled. The second motor 56 drives the pulley 54 to rotate, and the pulley 54 drives the outer cylinder to rotate, so as to cooperate with the welding assembly 10 to complete the welding work between the outer cylinder and the end cap.

[0035] As an optional implementation, the welding assembly 10 includes: The third support plate 60 is fixed to the top of the first mounting bracket 1; The fifth cylinder 61 is fixedly mounted on one side of the third support plate 60; The second mounting plate 62 is slidably connected to one side of the third support plate 60. One end of the second mounting plate 62 is fixedly connected to the telescopic rod of the fifth cylinder 61, and the second mounting plate 62 passes through the top of the first mounting frame 1. The welding torch 63 is fixed on the second mounting plate 62.

[0036] like Figure 1 and Figure 9 As shown, the second mounting plate 62 is moved by the fifth cylinder 61, and the second mounting plate 62 moves the welding gun 63 to the engagement point between the outer cylinder and the end cap. The welding gun 63 then works to complete the welding work between the outer cylinder and the end cap.

[0037] As an optional implementation, the unloading assembly 11 includes: The second inclined plate 64 is disposed above the roller 4, and a connecting plate 65 is fixedly provided on the middle part of the second inclined plate 64 extending downward. The fifth guide rod 66 is inserted through the connecting plate 65, and the two ends of the fifth guide rod 66 are respectively fixed with the third support 67; A threaded rod 68 is threaded through the connecting plate 65 and connected by threads. A fourth support 69 is fixed at both ends of the threaded rod 68. The second gear 70 is sleeved on the threaded rod 68 and fixedly connected; The second rack 71 has one end fixedly connected to the side of the first mounting plate 3, and the second rack 71 meshes with the second gear 70; The collection box 72 is located on the third support 67 at a point away from the first mounting plate 3.

[0038] like Figure 1 , Figure 10 and Figure 11As shown, in the initial stage, the second inclined plate 64 is located between the roller 4 and the pulley 54. When the roller 4 drives the outer cylinder to move upward, the first mounting plate 3 drives the second rack 71 to move, the second rack 71 drives the second gear 70 to rotate, the second gear 70 drives the threaded rod 68 to rotate, the threaded rod 68 drives the connecting plate 65 to move, and the connecting plate 65 drives the second inclined plate 64 to move towards the collection box 72, moving out of the space between the roller 4 and the pulley 54. After the pulley 54 clamps the outer cylinder, the first mounting plate 3 resets and moves downward. The above steps are reversed to make the second inclined plate 64 reposition itself between the roller 4 and the pulley 54. After the outer cylinder and the end cover are welded together, the guide clamping assembly 9 releases the outer cylinder, causing the outer cylinder to fall onto the second inclined plate 64 and roll into the collection box 72, thus completing the unloading and collection of the outer cylinder.

[0039] The working principle is as follows: The outer cylinder feeding assembly 7 and the end cap feeding assembly 8 work together to complete the assembly of the outer cylinder and the end cap on the roller 4. The roller 4 has a V-shaped groove 6, which prevents the outer cylinder from rolling off. After the outer cylinder and the end cap are clamped and assembled, the lifting assembly 2 drives the first mounting plate 3 to move upward. The first mounting plate 3 drives the roller 4 to move upward through the first support 5. The roller 4 drives the outer cylinder to move upward into the guide clamping assembly 9. The guide clamping assembly 9, in conjunction with the rotating assembly, clamps the outer cylinder and guides and positions it. The rotating assembly drives the outer cylinder to rotate, and the welding assembly 10... Welding is performed at the joint between the outer cylinder and the end cap. During the upward movement of the first mounting plate 3, the unloading assembly 11 is moved to the side of the first mounting plate 3. After the first mounting plate 3 is reset, the unloading assembly 11 is reset to below the guide clamping assembly 9. After the welding of the outer cylinder and the end cap is completed, the guide clamping assembly 9 is reset, and the outer cylinder falls onto the unloading assembly 11. It is then transferred to the next process through the unloading assembly 11. This invention not only achieves uniform rotation speed of the outer cylinder and improves welding accuracy, but also realizes the purpose of automatic feeding, automatic welding, and automatic unloading of the outer cylinder and end cap of the automotive shock absorber.
