Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a filter cover welding device. Background Technology

[0002] Filters typically filter fluids using filter elements. When fluid enters a filter element containing a filter screen or filter material of a certain size, impurities are blocked, while clean fluid flows out through the filter element, thus achieving the purpose of purifying the fluid. The hexagonal cover of a truck filter is an important component, usually located at the top or bottom of the filter. Its shape is regular hexagonal, making it easy to install and remove using a regular wrench or socket wrench. The hexagonal cover is usually connected to the filter housing by welding.

[0003] When welding the filter housing and hexagonal cap using a welding device, the hexagonal cap needs to be inserted into the welding head of the welding device, and the filter housing is placed outside the positioning ring and positioning block of the welding device. The welding head is controlled by a hydraulic mechanism to press down and weld the hexagonal cap and the filter housing. After welding, the welding head automatically rises, and the filter housing can be removed. However, because the hexagonal cap and the inner wall of the welding head are in close contact, during continuous welding operations, the welding head is prone to lifting the hexagonal cap and the welded filter housing simultaneously. After the welding head rises to the highest position, the hexagonal cap falls off, causing the filter housing to fall, affecting the operator's efficiency and potentially causing deformation of the filter housing surface due to the impact of the fall. Utility Model Content

[0004] The purpose of this invention is to solve the problem that, due to the close contact between the hexagonal cover and the inner wall of the welding head, during continuous welding operations, the welding head is prone to lifting the hexagonal cover and the completed filter housing simultaneously. After the welding head reaches its highest position, the hexagonal cover falls off, causing the filter housing to fall, affecting the operator's efficiency and potentially causing deformation of the filter housing surface due to the impact of the fall. Therefore, this invention proposes a filter cover welding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a filter cover welding device, comprising a body, a hydraulic rod provided on one side of the top of the body, an output rod of the hydraulic rod having a machine head, a welding head provided at the bottom of the machine head, a placement groove for placing a hexagonal cover being opened inside the welding head, a support plate fixedly connected to one side of the outer surface of the body, a positioning plate fixedly connected to the outer surface of the support plate, a filter housing fitted on the outer surface of the positioning plate, a control pedal provided on one side of the bottom of the body, an upper electrode and a lower electrode respectively connected to the outer surfaces of the welding head and the positioning plate, and a positioning device provided on the outer surface of the support plate to further restrict the position of the filter housing on the outer surface of the positioning plate to prevent the welding head from rising and causing the filter housing to rise.

[0006] Preferably, the positioning device includes a grooved rod, the bottom end of which is fixedly connected to one side of the top of the bearing plate. A rectangular rod is slidably connected to the inner wall of the grooved rod. A positioning block is fixedly connected to one end of the rectangular rod. The bottom edge of the positioning block away from the rectangular rod is arc-shaped. A spring is provided at one end of the rectangular rod. The two ends of the spring are fixedly connected to one end of the rectangular rod and one side of the inner wall of the grooved rod, respectively.

[0007] The effect achieved by the above components is as follows: When welding the filter housing and the hexagonal cover using the welding device, the top of the hexagonal cover is inserted upwards into the welding head. Then, the rectangular rod inside the groove rod at the top of the support plate controls the positioning block to move away from the positioning plate and compresses the spring, placing the bottom end of the filter housing on the outside of the positioning plate. Then, the rectangular rod is released, and the spring inside the groove rod returns to its original state, pushing the rectangular rod and the positioning block towards the positioning plate. This causes the bottom arc edge of the positioning block, away from the rectangular rod, to lock onto the outside of the bottom end of the filter housing. Finally, the operation of the machine is controlled by the control box on one side of the machine body. The parameters are set, and the hydraulic rod is extended by stepping on the control pedal, causing the machine head to lower the welding head. This allows the bottom of the hexagonal cover, which is stuck inside the welding head, to contact the top of the filter housing. Current is conducted through the upper and lower electrodes on the outside of the welding head and the positioning plate, generating resistance heat at the contact point between the filter housing and the bottom of the hexagonal cover, thus achieving welding. After welding, the hydraulic rod is retracted to raise the welding head. During the rise of the welding head, the position of the filter housing on the support plate is restricted by the positioning block. The hexagonal cover inside the welding head will detach from the inside of the welding head, preventing the filter housing from rising synchronously with the welding head.

[0008] Preferably, a rotating shaft is rotatably connected to one end of the top of the groove rod, a coil spring is provided at one end of the rotating shaft, and the two ends of the coil spring are fixedly connected to one side of the rotating shaft and one end of the top of the groove rod, respectively. A support rod is fixedly connected to the outer surface of the rotating shaft, and a pressure block is fixedly connected to the end of the support rod away from the rotating shaft. A top rod is fixedly connected to the top of the rectangular rod, and the top of the top rod contacts one side of the surface of the support rod.

[0009] The effect achieved by the above components is as follows: By setting the pressure block, when using the welding device, when the filter housing is placed on the outer surface of the support plate outside the positioning plate, during the process of pushing the rectangular rod to move away from the positioning plate, the top rod will push the support rod to control the support rod to rotate away from the top rod through the rotating shaft, and cause the coil spring to deform. After the filter housing is fitted onto the outer surface of the positioning plate, the spring inside the groove rod returns to its original state, pushing the rectangular rod and the positioning block to move towards the filter housing. After one side of the positioning block abuts against the outer surface of the filter housing, the coil spring at one end of the rotating shaft returns to its original state, which will drive the rotating shaft and the support rod to rotate towards the filter housing, so that one side of the pressure block rests on the outer top of the filter housing, further restricting the position of the filter housing on the support plate and improving the positioning effect of the filter housing.

[0010] Preferably, a rubber auxiliary strip is fixedly connected to the bottom end of the outer surface of the positioning block near the positioning disk.

[0011] The effect achieved by the above components is that by setting the rubber auxiliary strip, the positioning block fits more tightly against the outer surface of the filter housing, and the fixing effect is more stable.

[0012] Preferably, a protrusion is fixedly connected to one side of the rectangular rod, and the protrusion slides on one side of the inner wall of the groove rod.

[0013] The effect achieved by the above components is as follows: when the rectangular rod moves inside the groove, the protrusion on one side will slide on the inner wall side of the groove. When the rectangular rod is at the farthest end inside the groove, the protrusion can further limit the angle between the rectangular rod and the groove, and prevent the angle of the rectangular rod away from the groove from deflecting.

[0014] Preferably, an operating rod is fixedly connected to one side of the rectangular rod, and the operating rod slides on the inner wall of the groove rod near the outer surface of the rectangular rod.

[0015] The effect achieved by the above components is that when using the positioning device, holding the outer surface of the operating rod makes it easier and faster to push the rectangular rod to move and the support rod to rotate, which facilitates the placement of the filter housing or the removal of the filter housing.

[0016] Preferably, a cylinder is slidably connected to the outer surface of the operating rod, two locking blocks are fixedly connected to one end of the cylinder, and two locking slots are opened on one side of the groove rod.

[0017] The effect achieved by the above components is as follows: when using the welding device and the positioning device, after holding the outer surface of the operating rod and pushing the rectangular rod and the support rod to a position away from the positioning plate, the two locking blocks at one end of the cylindrical control cylinder on the outer surface of the operating rod can be pushed into the two locking slots on the outer surface of the groove rod, temporarily restricting the position of the rectangular rod and the support rod, which facilitates the inspection and maintenance of the positioning plate.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] In this invention, by setting a positioning device, and by installing movable positioning blocks and pressure blocks on the outer surface of the support plate, the positioning blocks and pressure blocks are respectively pressed against the bottom outer surface and top outer surface of the filter housing when welding the filter housing and the hexagonal cover. This further restricts the position of the filter housing on the support plate, avoids the problem of the filter housing rising synchronously with the welding head after welding and causing damage, and improves the practicality of the welding device.

[0027] Example 1, such as Figure 1-3As shown, a filter cover welding device includes a body 1. A hydraulic rod 3 is provided on one side of the top of the body 1. A machine head 4 is provided on the output rod of the hydraulic rod 3. A welding head 5 is provided at the bottom of the machine head 4. The welding head 5 has a placement groove for placing a hexagonal cover inside. A support plate 6 is fixedly connected to one side of the outer surface of the body 1. A positioning plate 7 is fixedly connected to the outer surface of the support plate 6. A filter housing 8 is sleeved on the outer surface of the positioning plate 7. A control pedal 9 is provided on one side of the bottom of the body 1. An upper electrode and a lower electrode are respectively connected to the outer surfaces of the welding head 5 and the positioning plate 7. A positioning device 2 is provided on the outer surface of the support plate 6 to further restrict the position of the filter housing 8 on the outer surface of the positioning plate 7 to prevent the welding head 5 from rising and causing the filter housing 8 to rise.

[0028] Reference Figure 1-6 As shown in this embodiment: the positioning device 2 includes a grooved rod 21, the bottom end of which is fixedly connected to one side of the top of the support plate 6. A rectangular rod 22 is slidably connected to the inner wall of the grooved rod 21. A positioning block 24 is fixedly connected to one end of the rectangular rod 22. The bottom edge of the positioning block 24 away from the rectangular rod 22 is arc-shaped. A spring 23 is provided at one end of the rectangular rod 22. The two ends of the spring 23 are fixedly connected to one end of the rectangular rod 22 and one side of the inner wall of the grooved rod 21, respectively. When welding the filter housing 8 and the hexagonal cover using a welding device, the top of the hexagonal cover is inserted upward into the welding head 5. Then, the rectangular rod 22 inside the grooved rod 21 is pushed at the top of the support plate 6 to control the positioning block 24 to move away from the positioning plate 7 and compress the spring 23, so that the bottom end of the filter housing 8 is fitted onto the outside of the positioning plate 7. Then, the rectangular rod 22 is released, and the spring 23 inside the grooved rod 21 returns to its original state and pushes... The rectangular rod 22 and the positioning block 24 move towards the positioning plate 7, so that the bottom arc edge of the positioning block 24 away from the rectangular rod 22 is locked on the outer side of the bottom of the filter housing 8. Then, the operating parameters of the machine body 1 are controlled by the control box on one side of the machine body 1, and the hydraulic rod 3 is extended by stepping on the control pedal 9, so that the machine head 4 drives the welding head 5 to descend, so that the bottom end of the hexagonal cover locked inside the welding head 5 contacts the top end of the filter housing 8. The current is conducted through the upper and lower electrodes on the outside of the welding head 5 and the positioning plate 7, so that the contact part between the filter housing 8 and the bottom end of the hexagonal cover generates resistance heat, thereby achieving welding. After welding is completed, the hydraulic rod 3 is controlled to retract and drive the welding head 5 to rise. During the rise of the welding head 5, the position of the filter housing 8 on the support plate 6 is restricted by the positioning block 24, and the hexagonal cover inside the welding head 5 will detach from the inside of the welding head 5, so that the filter housing 8 will not rise synchronously with the welding head 5.

[0029] Reference Figure 2-6As shown in this embodiment: a rotating shaft 25 is rotatably connected to one side of the top end of the grooved rod 21. A coil spring 26 is provided at one end of the rotating shaft 25. The two ends of the coil spring 26 are fixedly connected to one side of the rotating shaft 25 and one side of the top end of the grooved rod 21, respectively. A support rod 27 is fixedly connected to the outer surface of the rotating shaft 25. A pressure block 28 is fixedly connected to the end of the support rod 27 away from the rotating shaft 25. A top rod 29 is fixedly connected to the top end of the rectangular rod 22. The top end of the top rod 29 contacts one side of the surface of the support rod 27. By setting the pressure block 28, when the filter housing 8 is placed on the outer surface of the bearing plate 6 outside the positioning plate 7 using the welding device, the top rod pushes the rectangular rod 22 to move away from the positioning plate 7. 29 will push the support rod 27 to rotate away from the top rod 29 via the rotating shaft 25, causing the coil spring 26 to deform. After the filter housing 8 is fitted onto the outer surface of the positioning plate 7, the spring 23 inside the groove rod 21 returns to its original state, pushing the rectangular rod 22 and the positioning block 24 to move towards the filter housing 8. After one side of the positioning block 24 abuts against the outer surface of the filter housing 8, the coil spring 26 at one end of the rotating shaft 25 returns to its original state, which will drive the rotating shaft 25 and the support rod 27 to rotate towards the filter housing 8, so that one side of the pressure block 28 rests on the outer side of the top of the filter housing 8, further restricting the position of the filter housing 8 on the support plate 6 and improving the positioning effect of the filter housing 8.

[0030] Reference Figure 2-6 As shown in this embodiment: a rubber auxiliary strip 210 is fixedly connected to the bottom of the outer surface of the positioning block 24 near the positioning disk 7. By setting the rubber auxiliary strip 210, the positioning block 24 fits more tightly with the filter housing 8 when it abuts against the outer surface of the filter housing 8, and the fixing effect is more stable. A protrusion 211 is fixedly connected to one side of the rectangular rod 22. The protrusion 211 slides on one side of the inner wall of the groove rod 21. When the rectangular rod 22 moves inside the groove rod 21, the protrusion 211 on one side will slide on the inner wall side of the groove rod 21. When the rectangular rod 22 is located at the farthest end inside the groove rod 21, the protrusion 211 can further limit the angle between the rectangular rod 22 and the groove rod 21, and prevent the angle of the end of the rectangular rod 22 away from the groove rod 21 from deflecting.

[0031] Reference Figure 2-6As shown in this embodiment: an operating rod 212 is fixedly connected to one side of the rectangular rod 22. The operating rod 212 slides on the inner wall of the groove rod 21 near the outer surface of the rectangular rod 22. When using the positioning device 2, holding the outer surface of the operating rod 212 makes it easier and faster to push the rectangular rod 22 to move and the support rod 27 to rotate, which is convenient for placing the filter housing 8 or removing the filter housing 8. A cylinder 213 is slidably connected to the outer surface of the operating rod 212. Two locking blocks are fixedly connected to one end of the cylinder 213. 214. Two slots 215 are provided on one side of the groove rod 21. When using the welding device and the positioning device 2, after holding the outer surface of the operating rod 212 and pushing the rectangular rod 22 and the support rod 27 to a position away from the positioning plate 7, the cylinder 213 on the outer surface of the operating rod 212 can be pushed to control the two locking blocks 214 at one end of the cylinder 213 to enter the two slots 215 on the outer surface of the groove rod 21, temporarily restricting the position of the rectangular rod 22 and the support rod 27, which facilitates the inspection and maintenance of the positioning plate 7.

[0032] Working principle: When welding the filter housing 8 to the hexagonal cover using the welding device, insert the top of the hexagonal cover upwards into the welding head 5. Then, hold the outer surface of the operating rod 212 and push the rectangular rod 22 inside the slot rod 21 to control the positioning block 24 to move away from the positioning plate 7 and compress the spring 23. During the movement of the rectangular rod 22 away from the positioning plate 7, the top rod 29 will push the support rod 27 to control the support rod 27 to rotate away from the top rod 29 through the rotating shaft 25, causing the coil spring 26 to deform. Next, the bottom end of the filter housing 8 is fitted onto the outside of the positioning plate 7. Then, the rectangular rod 22 is released, and the spring 23 inside the groove rod 21 returns to its original state, which pushes the rectangular rod 22 and the positioning block 24 towards the positioning plate 7. This causes the bottom arc edge of the positioning block 24, away from the rectangular rod 22, to lock onto the outside of the bottom end of the filter housing 8. The coil spring 26 at one end of the rotating shaft 25 returns to its original state, which drives the rotating shaft 25 and the support rod 27 to rotate towards the filter housing 8, causing one side of the pressure block 28 to rest on the outside of the top end of the filter housing 8. The position of the filter housing 8 on the support plate 6 is restricted. Then, the operating parameters of the machine body 1 are controlled by the control box on one side of the machine body 1. By stepping on the control pedal 9, the hydraulic rod 3 is extended, causing the machine head 4 to drive the welding head 5 to descend. This allows the bottom end of the hexagonal cover inside the welding head 5 to contact the top end of the filter housing 8. Current is conducted through the upper and lower electrodes on the outside of the welding head 5 and the positioning plate 7, generating resistance heat at the contact point between the filter housing 8 and the bottom end of the hexagonal cover, thus achieving welding. After welding, the hydraulic rod 3 is controlled to retract, causing the welding head 5 to rise. During the rise of the welding head 5, the position of the filter housing 8 on the support plate 6 is restricted by the positioning block 24. The hexagonal cover inside the welding head 5 will detach from the inside of the welding head 5, preventing the filter housing 8 from rising synchronously with the welding head 5. After the welding head 5 moves away from the filter housing 8, the operating rod 212 is pushed to control the positioning block 24 and the pressure block 28 to move away from the outer surface of the filter housing 8, removing the filter housing 8. The next set of filter housings 8 and hexagonal covers is then welded.
