Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding equipment, in particular to a multi-station high-efficiency welding equipment for shock absorber oil storage cylinders. BACKGROUND

[0002] In the production process, the problem of welding slag and metal splashing during welding is a very common and multi-technical process problem. Splashing not only affects the appearance of the weld and increases the cleaning cost, but also may cause safety hazards.

[0003] In the welding process, the corresponding tooling fixture is generally used to position and process the workpiece to be welded. However, in order to position and clamp workpieces of different shapes, the welding fixture is usually designed with complex geometric structures, including numerous jaws, positioning pins, blocks, pressure arms and other components. These structures form a large number of narrow gaps, dead angles and irregular spaces. Welding slag is a splashing of high-temperature molten metal that is firmly bonded to the surface of the metal fixture after cooling. After long-term accumulation, it may damage the fixture itself during subsequent forced removal. In the operation process, in order to ensure the overall processing quality, it is inevitable to stop maintenance, and the production line is under tension, so the downtime is extremely valuable. Manual cleaning of the welding slag of the fixture is a very time-consuming task. Therefore, we propose a multi-station high-efficiency welding equipment for shock absorber oil storage cylinders to solve the above problems. SUMMARY

[0010] Preferably, the top of the clamping plate is provided with a blocking frame composed of a plurality of reset hollow frames, the bottom of the blocking frame is connected with an arc-shaped compression shaft, the top of the compression shaft is provided with an arc-shaped slot arranged in an open manner, the arc-shaped slot is made of elastic plastic material and is internally provided with a plurality of clamping pieces.

[0011] The top of the reset pressing plate is provided with a blocking ring, the blocking ring is located outside the clamping plate, the top of the blocking ring is provided with a plurality of transmission shafts, and the positions of the compression shafts are flush with those of the transmission shafts.

[0012] Preferably, the blocking ring frame consists of a set of fixed rings and several blocking shafts. The blocking shafts can be arranged in a staggered manner to reduce the splashing of welding slag. The blocking shafts are spring shafts that are inclined inward. Several straight grooves are opened on the surface of the blocking shafts to reduce the contact area with welding slag.

[0013] The blocking shaft has a through groove, and a heat dissipation metal plate is inserted inside the through groove. Several heat-resistant plastic shafts are provided on the heat dissipation metal plate to facilitate the collection of welding slag and other materials for subsequent processing.

[0014] Preferably, the bottom of the clamping base is provided with a plurality of rectangular slots arranged in a circular array, and an adjustable lifting block is installed inside the rectangular slot. A set of positioning shafts is provided on the top of the lifting block, and the positioning shafts pass through the reset pressure plate and are connected to the bottom of the transmission ring.

[0015] One end of the transmission ring is connected to a transmission pipe, which passes through the blocking ring frame and connects to an external suction device. Several recovery grooves are opened on the top of the transmission ring. During the reciprocating motion of the top reset pressure plate, the transmission ring can squeeze against the bottom of the blocking shaft, which can shake off the residual welding slag at the bottom. The negative pressure generated inside the recovery groove is used for recovery. The linkage design between the transmission ring and the drive ring frame can automatically vibrate and shake off the welding slag during welding intervals. With the detachable mesh plate and arc-shaped groove structure, it is easy to clean up the residual welding slag.

[0016] Preferably, the transmission ring is fitted with several heat-resistant mesh pieces, which are staggered with the recycling tank.

The dust collection ring forms a negative pressure with the help of the top air pump. The dust collection ring is used to adsorb the welding slag remaining at the clamping mechanism formed by the conveying base and the clamping plate. The welding slag is centrally collected through the negative pressure suction system, which significantly reduces cleaning and maintenance time, improves the continuous operation efficiency of the equipment, and also reduces the wear caused by welding slag on the clamping mechanism.

This significantly reduces cleaning and maintenance time, improves the continuous operation efficiency of the equipment, and also reduces the wear of welding slag on the clamping mechanism, extending the service life of the equipment.

[0021] 2. This invention effectively suppresses welding slag spatter and secondary rebound by adopting a spring shaft type blocking shaft structure with staggered high and low positions, reducing safety hazards during the welding process; at the same time, the design of the blocking ring and buffer pad further prevents welding slag from entering the movement gap of the clamping mechanism, ensuring stable operation of the equipment.

[0022] 3. The present invention can automatically vibrate and shake off welding slag during welding intervals through the linkage design of the transmission ring and the drive ring frame. Combined with the detachable mesh plate and arc groove structure, it is easy to clean up residual welding slag. The clamping plate adopts butt copper plate and heat dissipation metal plate, which not only enhances heat dissipation but also reduces welding slag adhesion and reduces maintenance complexity.

[0023] 4. This invention, through the clamping base equipped with a multi-position adjustable clamping plate and a buffer pad, can adapt to the precise fixing of oil storage cylinders of different sizes, avoiding displacement during the welding process; the copper sheet contact design can also improve heat dissipation efficiency and reduce the impact of thermal deformation on welding quality.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-8 This invention provides a technical solution: a multi-station high-efficiency welding device for shock absorber oil reservoir cylinders, characterized in that it includes:

[0036] The operating table 1 has a rotating turntable 11 on its top. Several clamping bases 4 are installed on the top of the turntable 11. The clamping bases 4 are used for limiting and clamping the oil storage cylinder. A positioning plate 2 is installed on one side of the operating table 1. A dust suction pipe 21 is provided on one side of the positioning plate 2. The dust suction pipe 21 is used for auxiliary separation and recycling of welding slag and for self-cleaning. An extension plate for connecting the welding frame 3 is provided at the rear end of the operating table 1.

[0037] The clamping base 4 has a reset pressure plate 41 on top, and a circular groove on top of the reset pressure plate 41. Several conveying bases 43 connected to the clamping plates 431 are located in the circular groove for clamping the oil reservoir. A blocking ring frame 44 is located on top of the reset pressure plate 41 to trap spattered welding slag. A transmission ring 46 for negative pressure suction of welding slag is located inside the circular groove. The transmission ring 46 is located at the bottom of the blocking ring frame 44. When welding is required on the shock absorber oil reservoir, the oil reservoir can be clamped between the clamping plates 431 for auxiliary positioning. In conjunction with the feeding motion of the welding frame 3, welding of the connecting parts can be performed, and the welding slag generated during the welding process can splash onto the inwardly inclined blocking ring. The top of the frame 44 can trap welding slag, and the staggered blocking shafts 45 can reduce the safety hazards caused by welding slag splashing. After welding is completed, the oil storage cylinder can be disassembled, and the clamping base 4 can be moved to the bottom of the suction pipe 21. As the drive ring frame 24 drives the bottom reset pressure plate 41 to reciprocate, the welding slag and other materials are shaken off. With the negative pressure inside the recycling tank 461 and the dust collection ring 26, most of the welding slag can be recycled, reducing the amount of welding slag and other materials remaining in the gaps of the clamping mechanism during long-term operation. Compared with the existing technology, the automated slag removal and circulating welding process reduces the dependence on manual cleaning, reduces the need for frequent intervention and maintenance, and thus effectively improves the overall production efficiency and equipment utilization rate.

[0038] like Figure 4 As shown, the bottom of the reset plate 41 is provided with several reset rods, and the reset rods are installed on the top of the clamping base 4. The top of the reset plate 41 is provided with several conveying grooves set inside the circular groove, and the conveying base 43 is movably set inside the conveying groove.

[0039] The inner wall of the clamping plate 431 is connected with a buffer pad. Both ends of the clamping plate 431 are provided with copper plates for pressing against the outer wall of the oil reservoir. The copper plates can improve heat dissipation efficiency and reduce the amount of welding slag residue.

[0040] like Figure 4 and Figure 8 As shown, a blocking frame 48 is installed on the top of the clamping plate 431. The blocking frame 48 is composed of several reset hollow frames. The bottom of the blocking frame 48 is connected to an arc-shaped compression shaft 481. The top of the compression shaft 481 is provided with an open arc-shaped groove 482. The arc-shaped groove 482 is made of elastic plastic and has several snap-fit ​​pieces inside. When the welding slag falls, it can be snapped between the snap-fit ​​pieces. During the movement of the conveyor seat 43, the compression shaft 481 and the transmission shaft 421 at the bottom can be squeezed to compact the welding slag inside the arc-shaped groove 482, which is convenient for subsequent disassembly, cleaning and maintenance.

[0041] A blocking ring 42 is installed on the top of the reset pressure plate 41. The blocking ring 42 is located outside the clamping plate 431. Several transmission shafts 421 are provided on the top of the blocking ring 42. The compression shaft 481 is flush with the transmission shaft 421. With the help of the blocking ring 42, it can abut against the inside of the blocking ring frame 44, reducing the amount of welding slag entering the clamping mechanism during the rebound process, and reducing the impact of welding slag getting stuck in the movement gap during long-term operation on the normal operation of the clamping mechanism.

[0042] like Figure 4 and Figure 5 As shown, the blocking ring frame 44 consists of a set of fixed rings and several blocking shafts 45. The blocking shafts 45 can be arranged in a staggered manner to reduce the splashing of welding slag. The blocking shafts 45 are spring shafts that are inclined inward. Several straight grooves are opened on the surface of the blocking shafts 45 to reduce the contact area with the welding slag. When welding slag splashes outward during the welding process, the blocking ring frame 44 of the corresponding size can intercept most of the welding slag. The staggered arrangement of the blocking shafts 45 reduces the accidental rebound of welding slag and reduces the safety hazards in the welding process.

[0043] The blocking shaft 45 has a through groove, and a heat dissipation metal plate is inserted inside the through groove. Several heat-resistant plastic shafts are set on the heat dissipation metal plate, and several straight grooves are set on the surface of the blocking shaft 45. This can effectively reduce the bonding area between the welding slag and the blocking shaft 45. In addition, the heat dissipation metal plate can also quickly dissipate heat, reduce the occurrence of heat during the disassembly of the oil reservoir, and facilitate subsequent cleaning.

[0044] like Figure 6 and Figure 7 As shown, the bottom of the clamping base 4 is provided with several rectangular slots arranged in a ring array, and an adjustable lifting block 47 is installed inside the rectangular slot. A set of positioning shafts 471 is provided on the top of the lifting block 47. The positioning shafts 471 pass through the reset pressure plate 41 and are connected to the bottom of the transmission ring 46.

[0045] One end of the transmission ring 46 is connected to a transmission pipe, which passes through the blocking ring frame 44 and connects to the external suction device. The top of the transmission ring 46 is provided with several recovery slots 461. During the reciprocating motion of the top reset plate 41, the transmission ring 46 can be squeezed against the bottom of the blocking shaft 45, which can shake off the residual welding slag at the bottom. The negative pressure generated inside the recovery slots 461 is used for recovery. When the clamping base 4 moves to the bottom of the suction pipe 21, it can push the drive ring frame 24 against the top of the transmission shaft 421. As the drive ring frame 24 moves in a circle, it can drive the bottom reset plate 41 to rise and fall repeatedly.

[0046] It should also be noted that the transmission ring 46 can be squeezed against the top blocking shaft 45, and the deformation of the blocking shaft 45 corresponding to the position of the recycling tank 461 is small, thus creating a large transmission gap between it and the adjacent blocking shaft 45. After the welding slag falls off, it can enter the recycling tank 461 through the transmission gap under the action of negative pressure, reducing the residue of welding slag on the top. It can self-clean during operation, reduce downtime maintenance time, and improve the overall processing efficiency.

[0047] like Figure 7 As shown, the transmission ring 46 is fitted with several heat-resistant mesh plates, and the mesh plates are staggered with the recycling tank 461. With the help of negative pressure adsorption, welding slag and other materials can be trapped in the gaps between the mesh plates, which makes it easier to disassemble and clean the mesh plates later, reducing the situation where welding slag blocks the inside of the transmission ring 46.

[0048] like Figure 2 As shown, a fixed slide rail 22 is provided on the surface of the positioning plate 2, and a transmission slider 23 connected to the docking ring frame 25 is movably provided on the fixed slide rail 22. The dust suction pipe 21 is located inside the docking ring frame 25, and the movement mechanism of the dust suction pipe 21 can be controlled to move it to the top of the clamping base 4, so as to play the role of cleaning and dust suction.

[0049] like Figure 2 and Figure 3 As shown, a vacuum pump 211 is connected to the top of the suction pipe 21. A drive ring frame 24 is rotatably installed inside the suction pipe 21. Several transmission slots are provided at the bottom of the drive ring frame 24, and the positions of the transmission slots correspond to the transmission shaft 421. The drive ring frame 24 is used to control the reciprocating motion of the reset pressure plate 41. A dust collection ring 26 is connected inside the drive ring frame 24. The dust collection ring 26 forms a negative pressure with the help of the top vacuum pump 211. The dust collection ring 26 is used to adsorb the welding slag remaining at the clamping mechanism formed by the conveying base 43 and the clamping plate 431. At this time, the outer side of the blocking frame 48 can be squeezed against the inner wall of the dust collection ring 26, which can clean the welding slag remaining on the blocking frame 48. Large particles fall into the arc groove 482 with gravity, and small particles enter the dust collection ring 26 with the airflow, which is convenient for subsequent unified processing.

[0050] Working principle: First, when welding is required on the shock absorber oil reservoir cylinder, the oil reservoir cylinder can be clamped between the clamping plates 431 for auxiliary positioning. Combined with the feed movement of the welding frame 3, the connecting parts can be welded. During welding, the weld slag can splash onto the top of the inwardly inclined blocking ring frame 44, which can trap the weld slag. The staggered blocking shafts 45 can reduce the safety hazards caused by weld slag splashing. After welding is completed, the oil reservoir cylinder can be disassembled, and the clamping base 4 can be moved to the bottom of the suction pipe 21. As the drive ring frame 24 drives the bottom reset plate 41 to reciprocate, the welding slag and other debris are shaken off. With the negative pressure inside the recycling tank 461 and the dust collection ring 26, most of the welding slag can be recycled, reducing the amount of welding slag and other debris remaining in the gaps of the clamping mechanism during long-term operation. During the clamping and positioning process, the oil storage cylinder can be locked between the clamping plates 431, and the appearance of indentations is reduced under the action of the buffer pad. During the welding process, the blocking frame 48 set on the top of the clamping plate 431 can reduce the amount of welding slag falling onto the clamping plate 431.

[0051] Furthermore, during the welding process, due to the presence of moving corners and the inherent quality of the welding mechanism, welding slag may splash outwards. Setting up a correspondingly sized blocking ring frame 44 can intercept most of the welding slag. The staggered blocking shafts 45 reduce the unexpected situation of secondary rebound of welding slag, thereby reducing safety hazards during the welding process. In addition, the surface of the blocking shafts 45 is provided with several straight grooves, which can effectively reduce the adhesion area between the welding slag and the blocking shafts 45. Furthermore, in conjunction with the heat dissipation metal plate, heat can be quickly dissipated, reducing the occurrence of heat during the disassembly of the oil reservoir and facilitating subsequent cleaning.

[0052] Finally, after disassembly, with the cooperation of the turntable 11, the clamping base 4 is moved to directly below the suction pipe 21, and the drive ring frame 24 is pressed against the top of the drive shaft 421. As the drive ring frame 24 rotates, it drives the bottom reset plate 41 to rise back and forth. At this time, the outer side of the blocking frame 48 can be squeezed against the inner wall of the dust collection ring 26, which can clean the welding slag and other residues on the blocking frame 48. Large particles fall into the arc groove 482 with gravity, and small particles enter the dust collection ring 26 with the airflow, which is convenient for subsequent unified processing. The drive ring 46 can be squeezed against the top blocking shaft 45, and the deformation of the blocking shaft 45 corresponding to the position of the recycling tank 461 is small, thus creating a large transmission gap between it and the adjacent blocking shaft 45. After the welding slag falls, it can enter the recycling tank 461 under the action of negative pressure along the transmission gap, reducing the residue of welding slag on the top. It can self-clean during operation, reduce downtime maintenance time, and improve the overall processing efficiency.
