Description

Technical Field

[0001] This invention relates to the field of stud welding equipment technology, and more particularly to a T-shaped welding cart. Background Technology

[0002] With the continuous development of steel structures, a large number of welded studs and bolts are used in metal buildings, high-rise buildings, machinery, large bridges, highways and viaducts. Welders find it difficult to handle and install short studs, while long studs are too heavy. Welders need to bend over to weld, and the electric arc and exhaust fumes cause health problems, fatigue, and lumbar muscle strain.

[0003] While some welding carts are currently capable of welding, their welding speed and efficiency are low, they cannot replace the speed of a worker, and they are inconvenient to use. Summary of the Invention

[0004] This invention addresses the problems existing in the background technology by proposing an automatic feeding T-shaped welding cart that has high welding efficiency and allows multiple welding guns to be connected in parallel on the cart.

[0005] The technical solution of the present invention: A T-shaped welding vehicle includes a frame and a movable frame. The movable frame is mounted on the frame, and wheels are provided at the bottom of the frame. A movable component is provided on the frame, and the movable frame is mounted on the movable component, allowing the movable frame to move arbitrarily on the frame. A gun barrel motor is provided on the movable frame, and a gun barrel is provided at the output end of the gun barrel. A welding gun and a stud ceramic ring chuck are provided in the middle of the gun barrel. A magazine rail is provided on the movable frame for placing welding studs.

[0011] Preferably, the end of the magazine track is provided with a magazine bolt clamp plate.

[0012] Preferably, a magazine drop switch is provided at the end of the magazine track.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1. This invention, by mounting a movable frame on a movable component, enables the movable frame to move on the vehicle frame, thereby allowing adjustment of the position of the weld studs on the movable frame.

[0025] Example 1

[0026] like Figures 1 to 8 As shown, the present invention proposes a T-shaped welding vehicle 1, which includes a frame 1 and a movable frame 7. The bottom of the frame 1 is provided with wheels 2. The movable frame 7 is provided on the frame 1. The frame 1 is provided with a movable component. The movable frame 7 is provided on the movable component, so that the movable frame 7 can move arbitrarily on the frame 1. The movable frame 7 is provided with a lifting motor 8.

[0027] refer to Figure 2 The movable frame is equipped with a gun rod motor 22, and the output end of the gun rod motor 22 is equipped with a gun rod 21. The middle part of the gun rod 21 is equipped with a welding gun 23 and a stud ceramic ring chuck 10.

[0028] Reference Figure 3 As shown, the movable frame 7 is equipped with a magazine rail 9.

[0029] Specifically, in this embodiment, the magazine track 9 is used to place welding studs;

[0030] More specifically, there are two magazine tracks 9, arranged parallel to each other on the moving frame 7. The welding studs mentioned in this embodiment are metal structures, cylindrical in shape, with the diameter of their tops larger than the diameter of their cylindrical bodies. Furthermore, a ceramic ring is provided on the outside of the welding stud. When inserting the welding stud into the magazine track 9, the welding stud needs to be placed inside the ceramic ring, which is then positioned within the magazine track 9.

[0031] Therefore, the gap in the magazine track 9 is larger than the diameter of the welding stud but smaller than the inner diameter of the ceramic ring. This ensures that the ceramic ring is placed on the magazine track 9 and that the welding stud can move within the magazine track 9.

[0032] Since the welding torch stud 10 is installed in the middle of the torch head of the torch rod 21, and the torch rod 21 is driven by the torch rod motor 22;

[0033] Taking a 250mm long welding stud as an example, during welding, the welding stud is clamped in the welding gun stud chuck 10, and the lifting motor 8 drives the lifting plate 11 to move 20mm.

[0034] Taking a 50mm long welding stud as an example, during welding, the welding stud is clamped in the welding gun stud chuck 10, and the lifting motor 8 drives the lifting plate 11 to move 220mm.

[0035] Therefore, the vertical shaft 5, driven by the vertical motor 6, can adjust the welding torch 23 and the stud ceramic ring chuck 10 to accommodate welding studs of different lengths, so that during welding, the lifting plate 11 driven by the lifting motor 8 has a low stroke and high welding efficiency.

[0036] The welding gun 23 can be moved to both ends of the horizontal axis, which extends beyond the vehicle body. This allows the vehicle body to be parallel to the edge of the workpiece, and the welding gun 23 can weld at the edge, increasing the welding range.

[0037] The frame 1 adopts a T-shaped structure, which can realize parallel welding of one or more welding torch stud chucks 10. Welding can be carried out on the side of the construction site edge, solving the problem that automatic welding cannot weld on the edge of the building. When the trolley is driven by the motor to turn, the speed of the two motors can be controlled to turn left and right. There is a hand handle for easy operation of the machine. The handle has a brake, which can stop the trolley when welding, so as not to run around and ensure the position and quality of the welding.

[0038] Reference Figure 2 As shown, in this embodiment, the end of the movable frame 7 is connected to the magazine track 9 via a support clamp 15.

[0039] Specifically, the two ends of the support clip 15 are hinged to the magazine track 9 and the moving frame 7 respectively, so that when the magazine track 9 moves, the moving frame 7 still supports the magazine track 9 through the support clip 15.

[0040] Continue to refer to Figure 2 As shown, in this embodiment, a displacement motor 16 is provided on the moving frame 7. The output end of the displacement motor 16 is connected to a moving block 18 through a lead screw 17. A track clamp 14 is provided on the moving block 18. The end of the track clamp 14 is connected to the magazine track 9. The end of the magazine track 9 is provided with a magazine bolt clamp plate 13.

[0041] Furthermore, when the displacement motor 16 is started, the displacement motor 16 will drive the lead screw 17 to rotate. When the lead screw 17 rotates, it will drive the moving block 18 to move. Since the moving block 18 is connected to the track clamp 14, the moving block 18 can drive the movement of the magazine track 9, thereby controlling the position of the magazine track 9 and adjusting the movement of the welding stud in the magazine track 9. The welding stud can be retracted and fed.

[0042] Each welding torch stud chuck 10 directly feeds studs to the magazine rail 9. The structure is simple and reliable. Multiple torches are arranged side by side, and each welding torch stud chuck 10 is equipped with its own corresponding feeding system (i.e., magazine rail 9). This also prevents the other parallel welding torch stud chucks 10 from running normally even if one of them fails during use, ensuring that the welding schedule is guaranteed.

[0043] In this embodiment, the spacing of the magazine rails 9 can be adjusted by adjusting the spacing of the rail clips 14. The spacing between the magazine rails 9 can be adjusted, thus enabling the adjustment of the size of the welding studs. The welding studs can be adjusted from 8mm to 32mm by adjusting the spacing between the two magazine rails 9.

[0044] The moving part includes a horizontal shaft 3 and a vertical shaft 5, with the horizontal shaft 3 mounted on the vertical shaft 5; a horizontal motor 4 is mounted at the end of the horizontal shaft 3, and a vertical motor 6 is mounted at the end of the vertical shaft 5.

[0045] The horizontal motor 4 drives the horizontal shaft 3 to move, and the vertical motor 6 drives the vertical shaft 5 to move. By moving the horizontal shaft 3 and the vertical shaft 5 vertically and horizontally, the position of the moving frame 7 can be adjusted.

[0046] The end of the lifting motor 8 is provided with a lifting plate 11, and the end of the gun rod 21 is provided with a ceramic ring clamp 12 for supporting the ceramic ring of the welding stud.

[0047] like Figures 5 to 8 As shown, a magazine drop switch 20 is provided at the end of the magazine rail 9.

[0048] The magazine drop switch 20 includes an active arm 201 and a driven arm 203. The ends of the active arm 201 and the driven arm 203 are provided with ejector pins 204, and a fixed arm 202 is provided in the middle. The fixed arm 202 is fixed to the magazine track 9.

[0049] The active arm 201 and the driven arm 203 are also provided with bearing grooves 2011, which are connected to the fixed arm 202 through bearings fixed in the bearing grooves 2011 respectively. The fixed arm 202 is provided with an arc-shaped waist hole 2021.

[0050] Furthermore, a waist hole is also provided on the driven arm 203, which partially overlaps with the arc-shaped waist hole 2021. The overlapping part passes through the driving arm 201, the fixed arm 202 and the driven arm 203, and a sliding bearing is provided through the arc-shaped waist hole 2021.

[0051] An adjusting block is provided at the end of the boom 203, and a pin 204 is provided on the adjusting block.

[0052] The ejector pin 204 is located in the slot of the magazine rail 9.

[0053] In this embodiment, by setting a feeding assembly on the side of the magazine track 9, the mutual cooperation of the ejector pins 204 achieves precise and automatic feeding of a single T-shaped welding nail each time. When a T-shaped welding nail needs to be fed, the nail drop switch rod 24 pushes the active arm 201 to move towards the magazine track 9 around the bearing set in the bearing groove 2011. At this time, the ejector pins 204 set on the end of the active arm 201 move away from the magazine track 9, so that the T-shaped welding nail located between the two ejector pins 204 is transported to the receiving assembly, waiting for the ceramic ring clamp 12 to clamp it. When the active arm 201 moves with the nail drop switch rod 24, the driven arm 203 also moves towards the magazine track 9 around the bearing set in the bearing groove 2011 on the driven arm 203. The power is that when the active arm 201 moves, the bearing in the arc-shaped waist hole 2021 moves accordingly, and drives the driven arm 203 to move in the opposite direction, so that the two ejector pins 204 move in opposite directions, thus cooperating to precisely and automatically feed a single T-shaped welding nail each time.

[0054] As a preferred embodiment, an adjusting block is provided at the end of the driven arm 203, and the ejector pin 204 is located on the adjusting block. The adjusting block is provided with a slot and is fixed to the driven arm 203 by screws. The size of the T-shaped welding studs can be adjusted to avoid feeding multiple T-shaped welding studs between the two ejector pins 204 at one time, further ensuring accurate feeding each time.

[0055] Example 2

[0056] like Figure 1 and Figure 3 As shown, in one embodiment of the present invention, a T-shaped welding vehicle is provided, compared to the embodiment of the present invention, in which a vibration motor 19 is provided between the track clamp 14 and the moving block 18.

[0057] When the vibration motor 19 starts, it can transmit vibration to the magazine track 9 through the track clamp 14. When the magazine track 9 vibrates, it can accelerate the movement of the supported ceramic ring and welding stud towards the magazine stud clamp plate 13.

[0058] Example 3

[0059] like Figures 1 to 8As shown, the present invention proposes a T-shaped welding cart. Compared with Embodiment 1, in this embodiment, the ceramic ring clamp 12 includes a fixing member 1201, a connecting member 1202, a connecting arm 1204, and a ceramic ring chuck 1207. The connecting member 1202 is mounted on the fixing member 1201, and the connecting arm 1204 and the ceramic ring chuck 1207 are detachably connected. The fixing member 1201 is connected to the transmission device through the connecting member 1202 to control the device to clamp the ceramic ring. The connecting arm 1204 and the ceramic ring chuck 1207 are detachable and replaceable. The connecting arm 1204 and the ceramic ring chuck 1207 can be connected by screws or by locking with clips. Replacing different connecting arms 1204 can greatly expand the applicability of the device and allow it to clamp more different types of ceramic rings. The bottom of the fixing member 1201 is hinged with two connecting rods 1203. The connecting rods 1203 and the connecting arm 1204 are detachably connected. The connecting rods 1203 are provided with opening and closing components. The cooperation between the opening and closing components and the lifting plate 11 is used to control the opening and closing degree of the two connecting rods 1203, thereby controlling the opening and closing degree between the two ceramic ring clamps 1207 connected to each other, and thus achieving the purpose of clamping control.

[0060] The inner side of the ceramic ring chuck 1207 is provided with a boss; the boss is located on the inner side of the two ceramic ring chucks 1207. The boss is used to ensure the position of the ceramic ring. If the ceramic ring is well protected, the quality of the welding will be increased and the welding will be more solid.

[0061] The two connecting rods 1203 installed at the bottom of the fastener 1201 are symmetrically designed; the two connecting rods 1203 hinged at the bottom of the fastener 1201 have the same structure, and both connecting rods 1203 are connected to the connecting arm 1204 and the ceramic ring clamp 1207. The connecting rods 1203 mainly play the role of connection and support control.

[0062] The opening and closing assembly includes a spring 1205, which is positioned between two connecting rods 1203. Each connecting rod 1203 is equipped with a bearing 1206. The bearings 1206 are connected to the connecting rods 1203. When the lifting plate 11 abuts against the bearing 1206, the bearing 1206 rotates. As the lifting plate 11 moves downward, the two connecting rods 1203 open and close, thereby causing the connecting arm 1204 and the ceramic ring clamp 1207 to open and close, achieving the purpose of clamping. When the connecting rods 1203 are opening and closing, the spring 1205 is in a stretched state. Therefore, when the ceramic ring clamp 1207 wraps around the ceramic ring and the lifting plate 11 moves upward, the connecting rods 1203 close under the spring action of the spring 1205. This closes the ceramic ring clamp 1207, allowing it to clamp against the outer wall of the ceramic ring. The opening and closing of the connecting rod 1203 can also be replaced by a cylinder or an elastic band. The lifting plate 11 slides on the two bearings 1206 to control the opening and closing state of the two connecting rods 1203.

[0063] The end of the lifting plate 11 is designed as an inverted triangle. The bottom of the lifting plate 11 is also designed as an inverted triangle. The purpose of this design is to allow the two sides of the inverted triangle to rub more smoothly on the bearing 1206, thereby making the movement of the lifting plate 11 more convenient and simple, and reducing resistance. However, the inverted triangle design at the bottom of the lifting plate 11 is only a preferred embodiment of the present invention. In other embodiments, the bottom of the lifting plate 11 may also adopt an arc-shaped design or a hemispherical design.

[0064] The bottom inner side of the ceramic ring chuck 1207 is inclined upward from the outside to the inside. This upward inclination of the bottom inner side of the ceramic ring chuck 1207 reduces the resistance when the ceramic ring enters the ceramic ring chuck 1207, making it faster and simpler.

[0065] The working principle of this equipment is as follows: The welding stud, fitted into the ceramic ring, is placed in the magazine track 9. Upon powering on, the displacement motor 16, lifting motor 8, and gun barrel motor 22 all reset, placing the magazine on its outermost position. The welding gun 23 and gun barrel 21 rise to their highest positions, causing the ceramic ring clamp 12 to exert a pushing force against the lifting plate 11, opening the ceramic ring slightly above the stud clamp 10. The displacement motor 16 then starts, enabling the lead screw 17 to move the moving block 18. The movement of the moving block 18, in turn, moves the vibration motor 19 and the bottom track clamp 14. As the track clamp 14 and support clamp 15 move, the end of the magazine track 9 closest to the magazine stud clamp plate 13 moves. The active arm 201 of the magazine stud drop switch 20 pushes against the stud drop switch top rod 24, causing the welding stud in the magazine track 9 to slide onto the magazine stud clamp plate 13.

[0066] At this time, the lifting motor 8 will drive the lifting plate 11 to move downwards, while the gun rod motor 22 remains stationary. The ceramic ring clamp 12 is still on the welding gun stud chuck 10, and the welding gun 23 moves downwards. The welding gun stud chuck 10 holds the stud. At this time, the lifting motor 8 will drive the lifting plate 11 to move upwards, and the welding gun stud chuck 10 will hold the stud. The stud is moved upwards by the welding gun stud chuck 10, and the ceramic ring clamping distance is about 28mm. The gun rod motor 22 reverses, and the gun rod moves downwards. Since the lifting plate 11 is stationary, the triangle becomes smaller, and the bearing 1206 retracts.

[0067] At this time, due to the elastic force of the spring 1205, the internal space of the ceramic ring chuck 1207 becomes smaller, thus clamping the ceramic ring.

[0068] The lifting motor 8 moves upward by approximately 5mm, causing the magazine bolt clamp plate 13 and displacement motor 16 to flip and retract the magazine. At this point, the lifting motor 8 moves downward, bringing the welding stud into contact with the workpiece. The gun barrel motor 22 lowers the ceramic ring, ensuring it contacts the workpiece and protects the welding position. The welding machine is then started with high current for welding. After welding, the gun barrel motor 22 and the lifting motor 8 return to their initial positions, allowing the wheel to move to another welding position. This process is repeated to perform the welding operation.

[0069] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
