Description

Technical Field

[0001] The invention relates to the technical field of welding devices, in particular to a welding device for splicing and processing hardware accessories. Background Art

[0002] Welding is a manufacturing process and technology that uses heat, pressure, or both to achieve atomic bonding between two or more separate workpieces (usually metals or thermoplastic materials) at their connection interface, thereby forming a permanent and strong connection structure.

[0003] There are many welding methods at present, among which arc welding is the most widely used. Arc welding is a process that uses an electric arc as a heat source for welding. During the arc welding process, when the voltage between the two electrodes is high enough, a gas conductive channel, namely an arc, will be formed between the two electrodes. The arc can generate a high temperature of up to several thousand degrees Celsius, which is enough to melt the workpiece and filler material. The molten metal then cools and solidifies to form a solid weld, thereby connecting the workpieces together.

[0004] Arc welding is usually used in the process of splicing hardware accessories. However, during the welding process, a large amount of waste chips are often attached to the surface of the table or workbench, which is inconvenient for users to clean, consumes a lot of manpower and material resources, reduces the work efficiency of users, and reduces the efficiency of the use of the device.

[0005] Therefore, a welding device for splicing and processing hardware accessories is proposed. Summary of the invention

[0006] The first purpose of the present invention is to provide a welding device for splicing hardware accessories, which can facilitate the user to move the welding platform and adjust the height of the welding platform according to the device. At the same time, after the welding of the workpiece is completed, it is convenient for the user to clean and collect the waste chips attached to the surface of the welding platform, thereby improving the use efficiency of the device to solve the problems raised in the above-mentioned background technology.

[0007] The present invention provides a welding device for splicing and processing hardware accessories, comprising a welding platform, a rectangular groove is provided on the outer surface of the lower end of the welding platform near one side, a cylinder is fixedly connected to the top of the inner surface of the rectangular groove, a universal wheel is fixedly connected to the outer surface of the lower end of the cylinder, a clamping groove is provided on the outer surface of one side of the welding platform, a clamping block is clamped inside the clamping groove, a storage groove is fixedly connected to the outer surface of one side of the clamping block, the storage groove is L-shaped, a sliding groove is provided on the outer surface of the front end of the welding platform, and a cleaning device is slidably connected inside the sliding groove.

[0008] By adopting the above technical solution, the device can facilitate the user to move the welding platform, and the height of the welding platform can be adjusted according to the device. At the same time, after welding the workpiece, the user can easily clean and collect waste chips attached to the surface of the welding platform, thereby improving the use efficiency of the device.

[0009] Preferably, a fixing rod is fixedly connected to the top of the inner surface of the rectangular groove near one side, a pressure spring is arranged inside the fixing rod, a telescopic rod is sleeved on the fixing rod, a threaded hole is opened on the outer surface of one side of the fixing rod, and a bolt is threadedly connected to the inner surface of the threaded hole.

[0010] By adopting the above technical solution, the user can adjust the extension length of the telescopic rod in the fixed rod by passing the bolt through the threaded hole to the telescopic rod. By arranging a pressure spring inside the fixed rod, the telescopic rod can be pressed against the ground, thereby reducing the labor of the user.

[0011] Preferably, a rotating shaft is provided on the outer surface of the lower end of the telescopic rod, and a supporting plate is movably connected to the outer surface of the lower end of the telescopic rod, and the rotating shaft is embedded in the interior of the supporting plate.

[0012] By adopting the above technical solution, the rotating shaft is embedded in the inside of the support plate, so that the welding platform can be tilted by adjusting the cylinder after the welding of the workpiece is completed. However, through the cooperation of the rotating shaft and the support plate, the support plate can be parallel to the ground to adapt to welding platforms with different tilt angles.

[0013] Preferably, the cleaning device is in a U-shaped structure, and a sliding rod is fixedly connected to a position near the top of one side of the inner surface of the cleaning device, and the annular outer surface of the sliding rod is engaged with the inner surface of the slide groove.

[0014] By adopting the above technical solution, the U-shaped cleaning device can be folded at an angle when idle until it contacts one side surface of the welding platform, thereby reducing the impact of the cleaning device on the welding platform when working.

[0015] Preferably, a shovel plate is fixedly connected to the outer surface of the front end of the cleaning device, and the shovel plate is inclined at an angle of 60 degrees to the welding platform.

[0016] By adopting the above technical solution, the shovel plate inclined at a 60-degree angle can facilitate the user to clean the waste chips attached to the surface of the welding platform while pulling the cleaning device, thereby reducing the user's labor and improving the use efficiency of the device.

[0018] By adopting the above technical solution, by providing a handle and a rubber layer, the hard contact of the handle with the user's palm can be reduced, the provision of universal wheels can facilitate the user to move the welding platform, and the self-locking device can reduce the probability of the welding platform moving during use.

[0019] Preferably, a spray assembly is provided inside the cleaning device, and the spray assembly includes a gear sleeved and fixed on the sliding rod. A cavity is opened inside the cleaning device at a position corresponding to the sliding rod. A reciprocating screw is rotatably connected inside the cavity, and one end of the reciprocating screw is fixedly connected to the sliding rod. A tooth plate meshing with the gear is fixed on the lower side of the inner part of the slide groove.

[0020] By adopting the above technical solution, when the user flips the cleaning device and the shovel plate contacts the surface of the welding platform, the sliding rod is located inside the slide groove, and the gear is engaged with the tooth plate. When the cleaning device is moved and the shovel plate is used to scrape and clean the surface of the welding platform, the gear drives the sliding rod to rotate.

[0021] Preferably, the external spiral transmission of the reciprocating screw is connected to a piston plate, an injection hole is provided on the top of the cleaning device, a one-way valve is built into the injection hole, the injection hole is connected to the cavity, a through groove is provided inside the cleaning device, and spray holes are provided at equal distances at one end of the shovel plate away from the cleaning device, and the spray holes are connected to the through groove.

[0022] By adopting the above technical scheme, when the sliding rod rotates, it drives the reciprocating screw to rotate, and the piston plate connected to the reciprocating screw spiral transmission inside the cavity moves back and forth left and right inside the wall. When the piston plate moves to the left, the outside air is sucked through the injection hole. Under the action of the one-way valve, the outside air can only enter but not exit. When the reciprocating screw moves to the right, the air inside the cavity is squeezed through the through groove and sprayed onto the surface of the welding platform by the spray hole to assist the shovel plate to clean the surface of the welding platform. The user can also connect the pipe to the injection hole, and the other end of the pipe is connected to the external cleaning liquid storage device. By sucking the cleaning liquid, the spray hole sprays the surface of the welding platform to assist in dissolving and cleaning the surface oil.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. By adding a series of structural components such as a welding platform, a cylinder and a support plate to the device, before the user uses the device to weld the workpiece, the user first starts the cylinder in the rectangular groove, and the cylinder is extended and retracted to make the universal wheel contact with the ground until the welding platform is separated from the ground. At this time, the user pushes the front end of the welding platform device, and then starts the cylinder to retract the universal wheel to make the welding platform contact with the ground. At this time, the user screws the bolt in the threaded hole, and under the action of the pressure spring, the support plate on the telescopic rod in the fixed rod is in contact with the ground, and then tightens the bolt. Under the action of the pressure spring, the user can easily pop out of the fixed rod when loosening the bolt to make the support plate contact with the ground, thereby playing a role in supporting and fixing the welding platform. At this time, the user places the workpiece on the surface of the welding platform for welding.

[0025] 2. By adding a series of structural components such as a cleaning device, a shovel plate and a storage groove to the device, when the workpiece is welded, the user starts the cylinder to make the heights of the two cylinders different, so that the welding platform reaches an inclined state, and then the user locks the universal wheel and loosens the bolts. Under the action of the pressure spring, the support plate is in contact with the ground. By setting a rotating shaft on the support plate, the support plate can be in parallel contact with the ground to adapt to welding platforms in different inclined states at different angles to achieve the purpose of supporting and stabilizing the welding platform. At this time, the user holds the handle on the cleaning device and pulls the cleaning device through the slide groove. While the cleaning device slides in the slide groove, The scraps attached to the surface of the welding platform can be scraped off by the shovel plate. When the scraps are separated from the surface of the welding platform, the inclined welding platform can cause the scraps to roll into the L-shaped storage groove. When the scraps in the storage groove reach a certain level, the user separates the card block on the storage groove from the card groove, thereby removing the storage groove to process the scraps in the storage groove. When the cleaning device is idle, the user moves the cleaning device to one side of the slide groove and then folds it in the slide groove through the sliding rod, so that the U-shaped cleaning device contacts the surface of one side of the welding platform, thereby reducing the impact of the cleaning device on the welding platform and improving the use efficiency of the device.

[0041] By adopting the above technical solution, the bolt 9 passes through the threaded hole 8 and reaches the telescopic rod 6, which makes it convenient for the user to adjust the extension length of the telescopic rod 6 in the fixed rod 5. By arranging the pressure spring 7 inside the fixed rod 5, the telescopic rod 6 can be made to reach the ground, thereby reducing the labor intensity of the user.

[0042] Specifically, Figure 1 and Figure 2 As shown, a rotating shaft 10 is disposed on the outer surface of the lower end of the telescopic rod 6 , a supporting plate 11 is movably connected to the outer surface of the lower end of the telescopic rod 6 , and the rotating shaft 10 is embedded in the interior of the supporting plate 11 .

[0043] By adopting the above technical solution, the rotating shaft 10 is embedded in the inside of the supporting plate 11, so that the welding platform 1 can be adjusted by the cylinder 3 to reach an inclined state after the welding of the workpiece is completed. However, through the cooperation of the rotating shaft 10 and the supporting plate 11, the supporting plate 11 can be made parallel to the ground to adapt to the welding platform 1 in different inclined angles.

[0044] Specifically, Figure 1 and Figure 4 As shown, the cleaning device 16 is in a U-shaped structure, and a sliding rod 17 is fixedly connected to one side of the inner surface of the cleaning device 16 near the top, and the annular outer surface of the sliding rod 17 is engaged with the inner surface of the slide groove 15.

[0045] By adopting the above technical solution, the U-shaped cleaning device 16 can be folded at an angle when idle until it contacts one side surface of the welding platform 1, thereby reducing the impact of the cleaning device 16 on the welding platform 1 when in operation.

[0046] Specifically, Figure 1 and Figure 4 As shown, a scraper plate 18 is fixedly connected to the front end outer surface of the cleaning device 16 , and the scraper plate 18 is inclined at an angle of 60 degrees to the welding platform 1 .

[0047] By adopting the above technical solution, the shovel plate 18 inclined at a 60-degree angle can facilitate the user to clean the waste attached to the surface of the welding platform 1 with the shovel plate 18 while pulling the cleaning device 16, thereby reducing the user's labor and improving the use efficiency of the device.

[0048] Specifically, Figure 1 and Figure 4 As shown, the outer surface of the lower end of the support plate 11 is provided with anti-slip grooves, the outer surface of the lower end of the cleaning device 16 is provided with a handle, the outer surface of the handle is wrapped with a rubber layer, and the universal wheel 4 is provided with a self-locking device.

[0050] Specifically, Figure 5 and Figure 4 As shown, a spray assembly is provided inside the cleaning device 16, and the spray assembly includes a gear 20 which is sleeved and fixed on the sliding rod 17. A cavity 21 is opened inside the cleaning device 16 at a position corresponding to the sliding rod 17. A reciprocating screw rod 22 is rotatably connected inside the cavity 21, and one end of the reciprocating screw rod 22 is fixedly connected to the sliding rod 17. A tooth plate 25 meshing with the gear 20 is fixed on the lower side of the inner part of the slide groove 15.

[0051] By adopting the above technical solution, when the user flips over the cleaning device 16 and the shovel plate 18 contacts the surface of the welding platform 1, the sliding rod 17 is located inside the slide groove 15, and the gear 20 is engaged with the tooth plate 25. When the cleaning device 16 is moved and the surface of the welding platform 1 is scraped and cleaned by the shovel plate 18, the gear 20 drives the sliding rod 17 to rotate.

[0052] Specifically, Figure 5 and Figure 4 As shown, the external spiral transmission of the reciprocating screw 22 is connected to a piston plate 23, an injection hole is provided at the top of the cleaning device 16, a one-way valve is built into the injection hole, the injection hole is connected to the cavity 21, a through groove 24 is provided inside the cleaning device 16, and a spray hole 19 is provided at an equal distance at one end of the shovel plate 18 away from the cleaning device 16, and the spray hole 19 is connected to the through groove 24.

[0053] By adopting the above technical scheme, when the sliding rod 17 rotates, it drives the reciprocating screw 22 to rotate, and the piston plate 23 connected to the reciprocating screw 22 in the cavity 21 moves back and forth left and right inside the wall.

When the reciprocating screw 22 moves to the right, the air inside the cavity 21 is squeezed through the through groove 24 and sprayed onto the surface of the welding platform 1 by the spray hole 19 to assist the shovel plate 18 in cleaning the surface of the welding platform 1. The user can also connect the injection hole through a pipeline, and the other end of the pipeline is connected to an external cleaning liquid storage device. By sucking the cleaning liquid, the spray hole 19 sprays the surface of the welding platform 1 to assist in dissolving and cleaning the surface oil stains.

[0054] Working principle: By adding a series of structural components such as welding platform 1, cylinder 3 and support plate 11 to the device, before the user uses the device to weld the workpiece, the user first starts the cylinder 3 in the rectangular groove 2, and the cylinder 3 is extended to make the universal wheel 4 contact with the ground until the welding platform 1 is separated from the ground. At this time, the user pushes the front end of the welding platform 1, and then starts the cylinder 3 to retract the universal wheel 4 to make the welding platform 1 contact with the ground. At this time, the user screws the bolt 9 in the threaded hole 8, and under the action of the pressure spring 7, the support plate 11 on the telescopic rod 6 in the fixed rod 5 is in contact with the ground. The user then tightens the bolt 9, and the pressure spring 7 allows the user to pop out of the fixed rod 5 when loosening the bolt 9, so that the support plate 11 contacts the ground, thereby supporting and fixing the welding platform 1. At this time, the user places the workpiece on the surface of the welding platform 1 for welding. By adding a series of structural components such as a cleaning device 16, a shovel plate 18 and a storage groove 13 to the device, when the workpiece is welded, the user starts the cylinder 3 to make the heights of the two cylinders 3 different, so that the welding platform 1 reaches a tilted state, and then the user locks the universal wheel 4, and then Loosen the bolt 9, and under the action of the pressure spring 7, the support plate 11 is in contact with the ground. By arranging the rotating shaft 10 on the support plate 11, the support plate 11 can be in parallel contact with the ground, so as to adapt to the welding platform 1 in an inclined state at different angles to achieve the purpose of supporting and stabilizing the welding platform 1. At this time, the user holds the handle on the cleaning device 16 and pulls the cleaning device 16 obliquely through the slide groove 15. The cleaning device 16 slides in the slide groove 15 and can remove the waste attached to the surface of the welding platform 1 through the shovel plate 18. When the waste is separated from the surface of the welding platform 1, due to the inclined welding platform The platform 1 can make the waste chips roll into the L-shaped storage groove 13. When the waste chips in the storage groove 13 reach a certain level, the user separates the block 14 on the storage groove 13 from the card groove 12, thereby removing the storage groove 13 to process the waste chips in the storage groove 13. When the cleaning device 16 is idle, the user moves the cleaning device 16 to one side of the slide groove 15 and then folds it in the slide groove 15 through the sliding rod 17, so that the U-shaped cleaning device 16 contacts the surface of one side of the welding platform 1, thereby reducing the influence of the cleaning device 16 on the welding platform 1 and improving the use efficiency of the device.

[0055] Instructions for use: Before the user uses the device to weld a workpiece, the user first starts the cylinder 3 in the rectangular groove 2, and the cylinder 3 is extended and retracted to make the universal wheel 4 contact with the ground until the welding platform 1 is separated from the ground. At this time, the user pushes the front end of the device of the welding platform 1, and then starts the cylinder 3 to retract the universal wheel 4 to make the welding platform 1 contact with the ground. At this time, the user screws the bolt 9 in the threaded hole 8, and under the action of the pressure spring 7, the support plate 11 on the telescopic rod 6 in the fixed rod 5 is in contact with the ground, and then tightens the bolt 9. Under the action of the pressure spring 7, it is convenient for the user to loosen the bolt 9 when the telescopic rod 6 pops out from the fixed rod 5 to make the support plate 11 contact with the ground, thereby playing the role of supporting and fixing the welding platform 1. At this time, the user places the workpiece on the surface of the welding platform 1 for welding. When the workpiece is welded, the user starts the cylinder 3 to make the heights of the two cylinders 3 different, so that the welding platform 1 reaches a tilted state, and then the user locks the universal wheel 4, and then loosens the bolt 9. Under the action of the pressure spring 7, the support plate 11 is in contact with the ground. The plate 11 is provided with a rotating shaft 10, which can make the support plate 11 parallel to the ground and adapt to the welding platform 1 in a tilted state at different angles to achieve the purpose of supporting and stabilizing the welding platform 1. At this time, the user holds the handle on the cleaning device 16 and pulls the cleaning device 16 through the slide groove 15. The cleaning device 16 slides in the slide groove 15 and can remove the waste attached to the surface of the welding platform 1 through the shovel plate 18. When the waste is separated from the surface of the welding platform 1, the waste can roll down into the L-shaped structure due to the tilted welding platform 1. In the storage groove 13, when the waste chips in the storage groove 13 reach a certain level, the user separates the block 14 on the storage groove 13 from the card groove 12, thereby removing the storage groove 13 to process the waste chips in the storage groove 13. When the cleaning device 16 is idle, the user moves the cleaning device 16 to one side of the slide groove 15 and then folds it in the slide groove 15 through the sliding rod 17, so that the U-shaped cleaning device 16 contacts the surface of one side of the welding platform 1, thereby reducing the impact of the cleaning device 16 on the welding platform 1 and improving the use efficiency of the device.
