Description

Technical Field

[0001] This application relates to the technical field of shock absorber manufacturing, and in particular to a fully automated assembly and welding equipment for shock absorber upper joints. Background Technology

[0002] Shock absorbers are important mechanical components widely used in automobiles, motorcycles, electric vehicles, and other fields. Their main function is to reduce vibration and impact, improving riding comfort and stability. A shock absorber primarily consists of a piston, piston rod, spring, seals, hydraulic fluid, working cylinder, reservoir cylinder, upper connector, and lower connector.

[0003] In related technologies, such as Figure 1 As shown, the upper connector includes a cover 101 and a sleeve 102. The cover 101 is used to connect to the piston rod of the shock absorber, and the sleeve 102 is used to connect to the motorcycle or electric vehicle body, ensuring that the shock absorber is securely installed on the vehicle. During assembly and welding, the cover 101 and the sleeve 102 need to be placed in a welding device and clamped and fixed by a welding fixture, so that the sleeve 102 is fixed on the upper side of the cover 101. Then, a welding machine is used to weld the connection between the sleeve 102 and the cover 101, thereby completing the assembly and welding of the upper connector.

[0004] In the existing technology, when welding the upper joint of the shock absorber, the staff needs to manually place the sleeve and cover of the upper joint into the welding fixture, clamp and fix them with the control fixture, and then operate the welding machine to weld. However, the manual feeding method not only wastes a lot of time and increases labor costs, but also affects the assembly and welding efficiency of the upper joint of the shock absorber. Summary of the Invention

[0005] To improve the assembly and welding efficiency of the upper joint of the shock absorber, this application provides a fully automatic assembly and welding equipment for the upper joint of the shock absorber.

One end of the positioning block passes through the inner side of one end of the heating element. The end of the positioning block extending out of the heating element is provided with a chamfer. When the positioning block is connected to the sleeve, the chamfer abuts against the inner wall of the sleeve.

[0026] By adopting the above technical solution, the sleeve can be limited from the inside, and together with the limiting mechanism, it forms a double limiting mechanism, which further improves the stability of the sleeve during the welding process. Moreover, as the positioning block moves, the upper joint can be automatically unloaded, improving its assembly and welding efficiency.

[0041] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0042] This application discloses a fully automated assembly and welding equipment for the upper joint of a shock absorber.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The fully automatic assembly and welding equipment for shock absorber upper joints includes a machine body 1, a first feeding mechanism 2 and a second feeding mechanism 3 respectively installed at both ends of the machine body 1, and a welding mechanism 4 installed on the machine body 1. The machine body 1 is used to ensure the stability of each mechanism. The first feeding mechanism 2 is used for stable feeding of the cover 101, and the second feeding mechanism 3 is used for stable feeding of the sleeve 102. It can transport the cover 101 and the sleeve 102 to the welding mechanism 4 for assembly and welding. The welding mechanism 4 is used to assemble and weld the cover 101 and the sleeve 102 together to form a complete upper joint. The welding mechanism 4 is equipped with a limiting mechanism 7 for clamping the sleeve 102 and fixing the position of the sleeve 102. A drive cylinder 6 for controlling the movement of the welding mechanism 4 is fixedly connected to the upper end of the machine body 1, and a pump for controlling the operation of the drive cylinder 6 and a control box for controlling the operation of the welding mechanism 4 are installed at the upper end of the machine body 1. A positioning component 5 for limiting the cover 101 is provided on the lower side of the welding mechanism 4.

[0044] In use, the cover 101 is transported to the upper side of the positioning part 5 by the first feeding mechanism 2, and the sleeve 102 is transported to the side of the welding mechanism 4 by the second feeding mechanism 3. The sleeve 102 is fixed to the side of the welding mechanism 4 by the limiting mechanism. Then, the drive cylinder 6 is started to push the welding mechanism 4 down until the outer wall of the sleeve 102 contacts the upper side of the cover 101. The welding mechanism 4 is used to weld the sleeve 102 to the upper side of the cover 101, thus completing the assembly and welding of the upper joint.

[0045] Reference Figure 2 , Figure 3 The first feeding mechanism 2 includes a first vibratory plate 21 mounted on the upper side of the machine body 1, a guide rail 22 fixedly connected to the first vibratory plate 21, and a first pushing mechanism 23 fixedly mounted on one side of the machine body 1. The first vibratory plate 21 consists of a vibrating seat and a spiral vibrating table. The vibrating seat drives the spiral vibrating table to vibrate, thereby uniformly guiding the cover 101 to the linear feeder 24. One end of the linear feeder 24 away from the first vibratory plate 21 is connected to one end of the first pushing mechanism 23, which is used to uniformly guide the cover 101 to the first pushing mechanism 23. One end of the first pushing mechanism 23 is connected to the upper end of the positioning member 5, which is used to transport the cover 101 to the upper side of the positioning member 5, thus completing the feeding of the cover 101.

[0046] Reference Figure 2 , Figure 3 and Figure 7 A linear feeder 24, which is fixedly connected to the machine body 1, is fixedly connected to the lower side of the guide rail 22. The guide rail 22 is a hollow tube with an opening on its upper side for displaying the forward path of the cover 101. The linear feeder 24 can drive the guide rail 22 to vibrate, so that the cover 101 can move linearly on the guide rail 22, allowing the cover 101 to stably enter the first pushing mechanism 23.

[0047] Reference Figure 2 , Figure 3 and Figure 8The first pushing mechanism 23 includes a first cylinder 231, a push block 232 fixedly connected to the piston rod of the first cylinder 231, and a guide plate 233 fixedly installed on the machine body 1. One side of the guide plate 233 is connected to one end of the guide rail 22. The cylinder body of the first cylinder 231 is fixedly connected to one end of the guide plate 233. A sliding groove 234 is provided on the upper side of the guide plate 233 for the push block 232 and the cover 101 to slide. The sliding groove 234 communicates with the guide rail 22 to ensure that the cover 101 can stably enter the sliding groove 234. One side of the positioning member 5 is connected to one end of the guide plate 233. The upper end of the positioning member 5 is provided with a positioning groove 51 for restricting the cover 101. The positioning groove 51 communicates with the sliding groove 234 so that the cover 101 can accurately slide into the positioning groove 51. The positioning component 5 has a feeding plate 9 connected to the machine body 1 on one side, which is used to guide the upper joint after the assembly and welding are completed, so as to facilitate unified collection and processing.

[0048] Reference Figure 2 , Figure 3 and Figure 5 Sensors are fixedly connected to the upper ends of the guide plate 233 and the guide track 22, respectively. One sensor is located adjacent to the guide track 22 and the guide plate 233 to detect the presence of the cover 101 and send a signal to the PLC controller in the control box to control the operation of the equipment. The other sensor is fixedly connected to the end of the guide track 22 opposite to the guide plate 233 and is used to detect the number of covers 101 entering the guide track 22.

[0049] When the cover 101 is conveyed into the chute 234 by the guide rail 22, the sensor detects the cover 101 and sends a signal to the PLC controller in the control box. At this time, the PLC controller controls the operation of the equipment, drives the first cylinder 231 to operate, pushes the slider to slide in the chute 234, thereby pushing the cover 101 to slide in the chute 234 until the cover 101 slides on the upper side of the positioning member 5, completing the feeding of the cover 101.

[0050] Reference Figure 2 , Figure 3 and Figure 5 The second feeding mechanism 3 includes a second vibratory plate 31 fixedly installed on the upper side of the machine body 1, an arc-shaped guide 32 fixedly connected to the second vibratory plate 31, and a second pushing mechanism 33 installed on the upper side of the machine body 1 and connected to the lower end of the arc-shaped guide 32. The arc-shaped guide 32 is used to guide the sleeve 102 into the second pushing mechanism 33. The second vibratory plate 31 consists of a vibratory seat and a spiral vibratory table. The vibratory seat is used to drive the spiral vibratory table to vibrate, thereby uniformly guiding the sleeve 102 to the arc-shaped guide 32. Then, the sleeve 102 rolls in the arc-shaped guide 32 until it enters the second pushing mechanism 33.

[0051] Reference Figure 5 , Figure 6 and Figure 9 The second pushing mechanism 33 includes a second cylinder 331 mounted on the upper side of the machine body 1, a movable platform 332 fixedly connected to one end of the piston rod of the second cylinder 331, and a loading plate 333 mounted on the upper side of the movable platform 332. The loading plate 333 is located on the arc-shaped guide member 32, and an installation groove 334 for inserting the sleeve 102 is opened on the upper side of one end of the loading plate 333. A limit rod 335 is slidably connected to the lower end of the movable platform 332. Limit blocks 336 fixedly connected to the machine body 1 are fixedly connected to both ends of the limit rod 335. The limit blocks 336 and the limit rod 335 are used to limit the movement of the movable platform 332, prevent misalignment during sliding, and ensure the smoothness of the sliding of the movable platform 332.

[0052] In use, the piston rod of the second cylinder 331 pushes the movable table 332 to slide along the limit rod 335 between the two limit blocks 336 until the mounting groove 334 is aligned with one side of the welding mechanism 4. At this time, the end of the loading plate 333 away from the mounting groove 334 is located at the lower end of the arc-shaped guide plate 233 to prevent the sleeve 102 inside from falling off and to ensure the stability of the sleeve 102 loading.

[0053] Reference Figure 2 , Figure 4 , Figure 6 and Figure 10 The welding mechanism 4 includes a connecting seat 41 located below the piston rod of the drive cylinder 6 and a heating element 42 mounted on one side of the connecting seat 41. A power cord connected to the heating element 42 is attached to one side of the connecting seat 41. The heating element 42 is used for electro-heating welding of the sleeve 102 and the cover 101. A positioning plate 61 connected to the piston rod of the drive cylinder 6 is attached to the upper side of the connecting seat 41 to ensure the stability of the connection between the connecting seat 41 and the drive cylinder 6. Another heating element 42 is installed inside the positioning member 5 for heating the cover 101. The heating element 42 is existing technology and will not be described further here.

[0054] When the sleeve 102 comes into contact with the cover 101, the sleeve and the cover 101 can be heated simultaneously by the energization of the two heating elements 42. Under resistance heating, the contact point heats up and melts rapidly until the contact point melts and welds together, thereby realizing the assembly and welding of the cover 101 and the sleeve 102.

[0055] Reference Figure 4 , Figure 6 and Figure 10The limiting mechanism 7 includes a third cylinder 71 fixedly installed on the connecting seat 41 and a limiting plate 72 fixedly connected to one end of the piston rod of the third cylinder 71. The piston rod of the third cylinder 71 passes through the inner walls of both ends of the connecting seat 41, and is used to drive the limiting plate 72 to move on one side of the connecting seat 41 to prevent misalignment during movement. The lower end of the limiting plate 72 is fixedly connected to a protrusion for hooking the sleeve 102, which is used to drive the sleeve 102 to contact the heating element 42.

[0056] In use, when the third cylinder 71 pushes the limiting plate 72 away from the connecting seat 41, the piston rod of the second cylinder 331 pushes the movable table 332 to move the loading plate 333 between the limiting plate 72 and the connecting seat 41 until the sleeve 102 moves directly above the positioning part 5. Then, the third cylinder 71 is controlled to retract, and the upper connector collar in the mounting groove 334 is hooked out by the protrusion under the limiting plate 72 until one end of the sleeve 102 contacts the heating element 42. At this time, the drive cylinder 6 is started to drive the connecting seat 41 to descend until the lower end of the sleeve 102 contacts the cover 101. Then, the sleeve 102 and the cover 101 are assembled and welded by the heating element 42.

[0057] Reference Figure 6 , Figure 10 A feeding mechanism 8 is installed at the lower end of the connecting seat 41. The feeding mechanism 8 includes a fourth cylinder 81 fixedly connected to one end of the connecting seat 41 and a positioning block 82 fixedly connected to the piston rod of the fourth cylinder 81. The positioning block 82 is slidably connected to the inner wall of the connecting seat 41 and one end passes through the inner side of the heating component. One end of the positioning block 82 is provided with a chamfer 821. When the limiting plate 72 drives the sleeve 102 to contact the heating element 42, the chamfer 821 of the positioning block 82 abuts against the inner wall of one end of the sleeve 102 to position and fix the sleeve 102. When the fourth cylinder 81 operates and pushes the positioning block 82 to gradually extend out of the connecting seat 41, it can drive the sleeve 102 away from the heating element 42. With the help of the chamfer 821, the upper joint after welding can easily slide down onto the feeding plate 9, thereby quickly completing the feeding of the upper joint.

[0058] Reference Figure 10 Multiple insertion rods 411 are fixedly connected to the upper end of the connecting seat 41, and a positioning plate 61 is fixedly connected to the lower end of the piston rod of the drive cylinder 6. The positioning plate 61 has multiple slots 62 for inserting the insertion rods 411. The connection between the insertion rods 411 and the slots 62 ensures convenient connection between the connecting seat 41 and the positioning plate 61. One end of each insertion rod 411 is fixedly connected to a disassembly plate 412 connected to the positioning plate 61. Pulling the disassembly plate 412 allows for quick disassembly of the connecting seat 41. In use, after inserting the insertion rods 411 into the slots 62, fasteners are used to fix the insertion rods 411 in the slots 62, thus fixing the connecting seat 41 to the lower side of the positioning plate 61.

[0059] The implementation principle of the fully automatic assembly and welding equipment for the upper joint of the shock absorber in this application embodiment is as follows:

[0060] When welding the joint, the first step is to start the first vibratory feeder 21 to guide the cover 101 to the guide rail 22, and start the second vibratory feeder 31 to guide the sleeve 102 to the arc-shaped guide 32 until the sleeve 102 rolls into the mounting groove 334 on the loading plate 333, thus completing the preparation work for loading the cover 101 and the sleeve 102.

[0061] Step 2: Start the linear feeder 24 to move the cover 101 in the guide rail 22 until the cover 101 moves into the slide groove 234 of the guide plate 233. At this time, the sensor detects the presence of the cover 101 and sends a signal to the PLC controller in the control cabinet to control the first cylinder 231 to operate. Through its piston rod, the push block 232 is pushed to slide in the slide groove 234 until the cover 101 is pushed to slide into the positioning groove 51 at the top of the positioning member 5, completing the feeding of the cover 101. Then, the first cylinder 231 retracts and resets.

[0062] Thirdly, after the cover 101 is positioned on the positioning member 5, the third cylinder 71 operates simultaneously, pushing the limiting plate 72 away from the heating element 42. At this time, the second cylinder 331 operates, pushing the movable table 332 to slide along the limiting rod 335, causing the device plate and sleeve 102 to move until one end of the loading plate 333 is between the limiting plate 72 and the heating element 42, and the sleeve 102 is aligned with the positioning block 82. At this time, the third cylinder 71 retracts, and the protrusion at the lower end of the limiting plate 72 hooks the sleeve 102 in the mounting groove 334, pulling it away from the mounting groove 334 until the sleeve 102 is fitted on the outside of the positioning block 82 and contacts the heating element 42, completing the loading of the sleeve 102. Subsequently, the second cylinder 331 retracts, driving the loading plate 333 back to its original position, causing another sleeve 102 to fall into the mounting groove 334, completing the waiting for the sleeve 102.

[0063] Step 4: Start the drive cylinder 6 to push the connecting seat 41 down until the sleeve 102 contacts the upper side of the cover 101. At this time, start the two heating elements 42 at the same time to heat the cover 101 and the sleeve 102 simultaneously, so that the contact point of the cover 101 and the sleeve 102 can be heated up quickly and melted together to complete the assembly and welding of the sleeve 102 and the cover 101.

[0064] Step 5: After welding is completed, drive cylinder 6 retracts to lift the upper connector. Then, third cylinder 71 pushes limit plate 72 away from heating element 42. At this time, fourth cylinder 81 operates to push positioning block 82 to move, thereby causing the upper connector to detach from heating element 42 and fall onto unloading plate 9, completing the unloading of the upper connector.

[0065] Step 6: Repeat the above steps to automatically complete the assembly and welding of the upper connector of the shock absorber. The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
