Description

Technical Field

[0001] The utility model relates to the technical field of steel cable welding, in particular to a welding tooling for fixing steel cables. Background Technique

[0002] During the welding process of steel cables and connectors, traditional welding toolings generally face the problem of out-of-control distance between the welding torch and the workpiece due to thermal deformation or rotational welding of the steel cables. In the prior art, some toolings use rigid tracks or manual adjustment of the welding torch position, which are difficult to adapt to the thermal expansion and dynamic offset during steel cable welding in real time. For example, during the welding of circumferential welds, if the distance between the welding torch and the connection of the steel cable is too close, it is extremely easy to cause local overheating and burning through of the steel cable, seriously affecting the strength of the welding joint; if the distance is too far, it will lead to defects such as insufficient penetration and lack of fusion. Although some devices attempt to achieve compensation for the welding torch position through sensors and electric adjustment mechanisms, such solutions have problems such as complex structure, high cost, response delay, etc., and the sensors are prone to data deviation in high-temperature welding environments, making it difficult to ensure the stability of welding quality.

[0003] Therefore, the utility model provides a welding tooling for fixing steel cables to solve the problems raised above. Content of the Utility Model

[0004] The purpose of the utility model is to provide a welding tooling for fixing steel cables to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A welding tooling for fixing steel cables includes a bottom plate and a welding torch. A welding machine assembly is installed on the upper surface of the bottom plate, and this assembly can automatically adjust the position of the welding torch. A clamping assembly for positioning the processing positions of two groups of steel cables is installed on the upper surface of the bottom plate, and a support assembly for supporting the connection of the two groups of steel cables is installed inside the clamping assembly.

[0007] As a further solution of the utility model, the welding machine assembly includes a track and a hinge. A slide rail is slidably connected inside the track, an electric adjustment arm is hinged at the upper end of the slide rail, the top end of the electric adjustment arm is hinged to a connecting plate through a hinge, a first side plate is installed on the upper surface of the connecting plate, a heat conducting rod and a shape memory alloy wire are installed at one end of the first side plate close to the welding machine assembly, the outer end of the heat conducting rod is slidably connected to a second side plate, the end of the shape memory alloy wire away from the first side plate is installed on one side of the second side plate close to the first side plate, a top plate is installed on the upper surface of the second side plate, and the welding torch is installed on the upper surface of the top plate.

[0008] As a further solution of the present utility model, the clamping assembly includes two groups of bases, both of the two groups of bases are installed on the upper surface of the bottom plate, a fixing plate is slidably connected to the upper end of the base, a rotating block is rotatably connected to the inside of the fixing plate, a fixed sleeve is rotatably connected to the inside of the rotating block, two arc-shaped positioning blocks are rotatably connected to the inside of the fixed sleeve, a connecting sleeve is slidably connected to the outer surface of the fixed sleeve, electromagnetic rings are installed on one side of the two fixing plates close to the cable connection end, a magnetic block is installed on the outer surface of the fixed sleeve, and the position of the magnetic block is inside the electromagnetic ring.

[0009] As a further solution of the present utility model, the support assembly includes a support plate, the support plate is slidably connected to the inside of the front fixing plate, a support block is installed on the upper surface of the support plate, and the position of the inner wall of the support block is parallel to the position of the outer surface of the fixed sleeve.

[0010] As a further solution of the present utility model, multiple iron blocks are installed inside the electromagnetic ring, and one side of the iron block away from the electromagnetic ring is adsorbed on the outer surface of the magnetic block.

[0011] As a further solution of the present utility model, a spring piece is installed on the inner wall of the fixed sleeve, the position of the spring piece is on the rotation path of the arc-shaped positioning block, and one side of the spring piece close to the arc-shaped positioning block is attached to the inner wall of the fixed sleeve.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. When the present utility model is in use, by keeping the end of the heat conduction rod away from the first side plate parallel to the lower end of the welding end of the welding torch, the heat generated during the welding process of the welding torch is conducted to the shape memory alloy wire by the heat conduction rod. When the end of the heat conduction rod away from the first side plate is closer to the cable connection point, the temperature rises faster. Then, due to the characteristics of the thermal deformation of the shape memory alloy wire, the heat of the heat conduction rod itself is conducted to the inner wall of the shape memory alloy wire, thereby causing the shape memory alloy wire to generate thermal contraction and pulling the second side plate to slide on the upper end of the connecting plate, so as to realize the precise adjustment of the position of the welding torch, and further avoid the cable connection point being burned through by welding due to being too close to the welding end of the welding torch during the rotation process, thus improving the practicability of the device; conversely, when the temperature of the heat conduction rod decreases, the shape memory alloy wire slowly elongates, making the welding torch return to a suitable position, and always maintaining the dynamic balance of the distance between the welding torch and the cable connection point.

[0014] 2. When the utility model is in use, by starting the electromagnetic ring to drive the magnetic block to drive the fixed sleeve to rotate inside the groove of the rotating block, the fixed sleeve drives the two groups of steel cables to rotate synchronously during the rotation process, so that the position of the steel cables does not need to be adjusted during the process of the welding component welding the joints of the two groups of steel cables comprehensively. Therefore, the time consumed by the device for welding the two groups of steel cables is shortened; by starting the electric telescopic rod to push the fixed plate to move up and down at the upper end of the base, and then starting the motor to drive the rotating block to rotate inside the groove of the fixed plate, the clamping component can clamp the steel cables at different angles during use, so that the device can weld the two groups of steel cables after installation during use, thus expanding the application range of the device.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 5 , in the embodiment of the present invention, a welding tooling for fixing steel cables includes a bottom plate 1 and a welding gun 3. A welding machine assembly 2 is installed on the upper surface of the bottom plate 1, and this assembly can automatically adjust the position of the welding gun 3. A clamping assembly 4 for positioning the processing positions of two groups of steel cables is installed on the upper surface of the bottom plate 1, and a support assembly 5 for supporting the connection part of the two groups of steel cables is installed inside the clamping assembly 4; specifically, by starting the welding machine assembly 2 to adjust the position of the welding gun 3 to the directly upper end of the steel cable connection part, and then due to the temperature self-adaptive adjustment characteristic of the welding machine assembly 2, the welding machine assembly 2 automatically adjusts the position of the welding gun 3 at the upper end of the steel cable, so as to avoid the situation that the distance between the steel cable connection part and the welding end of the welding gun 3 is too close during the rotation process, resulting in the steel cable connection part being burned through by welding, thus improving the practicability of the device.

[0027] The welding machine assembly 2 includes a track 201 and a hinge member 204. A slide rail 202 is slidably connected inside the track 201. The upper end of the slide rail 202 is hinged with an electric adjusting arm 203. The top end of the electric adjusting arm 203 is hinged with a connecting plate 206 through the hinge member 204. A first side plate 207 is installed on the upper surface of the connecting plate 206. A heat conducting rod 209 and a shape memory alloy wire 210 (the shape memory alloy wire 210 is a nickel-titanium-based shape memory alloy wire) are installed at one end of the first side plate 207 close to the welding machine assembly 2. The outer end of the heat conducting rod 209 is slidably connected with a second side plate 208. One end of the shape memory alloy wire 210 far from the first side plate 207 is installed on the side of the second side plate 208 close to the first side plate 207. A top plate 211 is installed on the upper surface of the second side plate 208. The welding gun 3 is installed on the upper surface of the top plate 211. The inner wall of the shape memory alloy wire 210 abuts against the outer surface of the heat conducting rod 209. A hinge member 204 is installed on the upper surface of the electric adjusting arm 203. A groove is formed on the upper surface of the hinge member 204. A fixing rod 205 is slidably connected inside the groove of the hinge member 204. The upper surface of the fixing rod 205 is installed on the lower surface of the connecting plate 206;

[0028] Specifically, by starting the electric adjustment arm 203, the welding gun 3 is pushed upward. Then, by pushing the sliding rail 202, the electric adjustment arm 203, and the connecting plate 206, the angle and position of the welding gun 3 at the upper end of the bottom plate 1 are adjusted. The position of the welding end of the welding gun 3 is adjusted to the exact upper end of the connection of the two groups of steel cables inside the clamping assembly 4, enabling the position of the welding gun 3 to be adjusted during use, thereby expanding the welding range of the welding gun 3. One end of the heat conduction rod 209 away from the first side plate 207 is kept parallel to the lower end of the welding end of the welding gun 3, allowing the heat conduction rod 209 to conduct the heat generated during the welding process of the welding gun 3 to the shape memory alloy wire 210. When the end of the heat conduction rod 209 away from the first side plate 207 gets closer to the connection of the steel cables, the temperature rises faster. Then, due to the thermo-deformation characteristics of the shape memory alloy wire 210, the heat of the heat conduction rod 209 itself is conducted to the inner wall of the shape memory alloy wire 210, causing the shape memory alloy wire 210 to generate thermal contraction and pull the second side plate 208 to slide on the upper end of the connecting plate 206, thereby achieving precise adjustment of the position of the welding gun 3, and further preventing the connection of the steel cables from being burned through by welding when the distance between the rotating connection of the steel cables and the welding end of the welding gun 3 is too close during rotation. Therefore, the practicality of the device is improved. Conversely, when the temperature of the heat conduction rod 209 decreases, the shape memory alloy wire 210 slowly elongates, causing the welding gun 3 to return to a suitable position, always maintaining the dynamic balance of the distance between the welding gun 3 and the connection of the steel cables.

[0029] Meanwhile, by fitting the inner wall of the shape memory alloy wire 210 to the outer surface of the heat conduction rod 209, the heat conduction rod 209 restricts the elongation or expansion length of the shape memory alloy wire 210, thus minimizing the excessive pushing of the second side plate 208 by the shape memory alloy wire 210 to drive the welding gun 3 to move.

[0030] The clamping assembly 4 includes two groups of bases 401. Both groups of bases 401 are installed on the upper surface of the bottom plate 1. A fixed plate 403 is slidably connected to the upper end of the base 401. A rotating block 404 is rotatably connected inside the fixed plate 403. A fixed sleeve 405 is rotatably connected inside the rotating block 404. Two arc-shaped positioning blocks 407 are rotatably connected inside the fixed sleeve 405. A connecting sleeve 406 is slidably connected to the outer surface of the fixed sleeve 405. An electromagnetic ring 408 is installed on one side of each of the two fixed plates 403 close to the cable connection end. A magnetic block 410 is installed on the outer surface of the fixed sleeve 405. The position of the magnetic block 410 is inside the electromagnetic ring 408. A motor 409 is installed on the side of the fixed plate 403 away from the welding machine assembly 2. An electric telescopic rod 402 is installed on the upper surface of the base 401. The output end of the electric telescopic rod 402 is installed on the lower surface of the fixed plate 403. A groove is formed on the upper surface of the fixed plate 403. Through holes are formed on both the front and rear sides of the groove of the fixed plate 403. The rotating block 404 is rotatably connected inside the two through holes of the fixed plate 403. The output shaft of the motor 409 passes through a through hole on the rear side of the fixed plate 403 and is installed on the back of the rotating block 404. A groove is formed inside the rotating block 404. The fixed sleeve 405 is rotatably connected inside the groove of the rotating block 404. Two card slots are formed on the outer surface of the fixed sleeve 405. Through holes are formed on both the front and rear inner walls of the card slots of the fixed sleeve 405. The arc-shaped positioning blocks 407 are rotatably connected inside the two through holes of the fixed sleeve 405;

[0031] Specifically, by moving two cables, the two cables are respectively sleeved inside the two fixed sleeves 405, and the adjacent ends of the two cables are fitted together. Then, by using an external object to push the connecting sleeve 406 to slide at the outer end of the fixed sleeve 405, the arc-shaped positioning block 407 is pushed to rotate inside the fixed sleeve 405 during the sliding process of the connecting sleeve 406. One end of the arc-shaped positioning block 407 close to the inner wall of the fixed sleeve 405 is abutted against the outer surface of the cable, thus completing the positioning of the two cables; when the adjacent ends of the two cables are being welded, by starting the electromagnetic ring 408 to drive the magnetic block 410 to drive the fixed sleeve 405 to rotate inside the groove of the rotating block 404, the fixed sleeve 405 drives the two cables to rotate synchronously during the rotation process, so that the welding machine assembly 2 does not need to adjust the position of the cables during the process of fully welding the connection of the two cables. Therefore, the time consumed by the device for welding the two cables is shortened;

[0032] At the same time, by starting the electric telescopic rod 402, the fixed plate 403 is pushed up and down on the upper end of the base 401, and then the rotating block 404 is driven to rotate inside the groove of the fixed plate 403 by starting the motor 409, so that the clamping assembly 4 can clamp steel cables at different angles during use, and then the device can weld two sets of installed steel cables during use, thereby expanding the scope of application of the device and improving the practicality of the device.

[0033] The support assembly 5 includes a support plate 501, which is slidably connected to the interior of a set of fixed plates 403 on the front side. A support block 502 is installed on the upper surface of the support plate 501. The inner wall of the support block 502 is parallel to the outer surface of the fixed sleeve 405. The inner wall of the support block 502 abuts the lower surface of the connection between the two sets of steel cables.

[0034] Specifically, when the two groups of steel cables are welded and fixed, the support block 502 is moved by pushing the support plate 501, and the position of the support block 502 is adjusted to the lower end of the connection between the two groups of steel cables. Then, the position of the inner wall of the support block 502 and the position of the outer surface of the fixing sleeve 405 are kept parallel, so that the inner wall of the support block 502 abuts against the outer surface of the two groups of steel cables, and the support assembly 5 supports the connection between the two groups of steel cables, thereby preventing the connection between the two groups of steel cables from falling during the welding heating process, which may cause errors in the welding and fixing of the two groups of steel cables.

[0035] Multiple groups of iron blocks 6 are installed inside the electromagnetic ring 408, and the side of the iron block 6 away from the electromagnetic ring 408 is adsorbed on the outer surface of the magnetic block 410. The inside of the electromagnetic ring 408 is provided with multiple groups of grooves, and the iron block 6 is installed inside the grooves of the electromagnetic ring 408; specifically, the side of the iron block 6 away from the electromagnetic ring 408 is attached to the outer surface of the magnetic block 410, so that when the electromagnetic ring 408 is closed, the magnetic block 410 uses its own magnetic force to adsorb on the side of the iron block 6 away from the electromagnetic ring 408, thereby making the iron block 6 limit the rotation position of the magnetic block 410 and the fixed sleeve 405 during use, thereby avoiding the fixed sleeve 405 from rotating when the electromagnetic ring 408 is closed, thereby improving the stability of the clamping assembly 4 during use.

[0036] A spring piece 7 is installed on the inner wall of the fixed sleeve 405, and the position of the spring piece 7 is located on the rotation path of the arc-shaped positioning block 407. The side of the spring piece 7 close to the arc-shaped positioning block 407 is in contact with the inner wall of the fixed sleeve 405; specifically, during the rotation process of the arc-shaped positioning block 407, one end of the spring piece 7 is pushed to stretch inside the fixed sleeve 405, so that after the staff pushes the connecting sleeve 406 to reset, the spring piece 7 uses elastic recovery to drive itself to push the arc-shaped positioning block 407 to automatically reset, so that the staff does not need to manually adjust the position of the reset arc-shaped positioning block 407.

[0037] The working principle of the present utility model is as follows:

[0038] When the present utility model is in use, the welding gun 3 is pushed upward by starting the electric adjusting arm 203. Then, the angle and position of the welding gun 3 on the upper end of the base plate 1 are adjusted by pushing the sliding rail 202, the electric adjusting arm 203 and the connecting plate 206, and the position of the welding end of the welding gun 3 is adjusted to the exact upper end of the connection of two groups of steel cables clamped inside the clamping assembly 4. One end of the heat conduction rod 209 away from the first side plate 207 is kept parallel to the lower end of the welding end of the welding gun 3, so that the heat generated during the welding process of the welding gun 3 is conducted to the shape memory alloy wire 210 by the heat conduction rod 209. When the end of the heat conduction rod 209 away from the first side plate 207 is closer to the connection of the steel cables, the temperature rises faster. Then, due to the characteristic of heat deformation of the shape memory alloy wire 210, the heat of the heat conduction rod 209 itself is conducted to the inner wall of the shape memory alloy wire 210, so that the shape memory alloy wire 210 generates heat shrinkage and pulls the second side plate 208 to slide on the upper end of the connecting plate 206, thereby realizing the precise adjustment of the position of the welding gun 3, and further avoiding the steel cable connection being burned through by welding due to being too close to the welding end of the welding gun 3 during the rotation process.

[0039] Meanwhile, by moving two groups of steel cables, the two groups of steel cables are respectively sleeved inside two groups of fixed sleeves 405, and the adjacent ends of the two groups of steel cables are abutted against each other. Then, by using an external object to push the connecting sleeve 406 to slide on the outer end of the fixed sleeve 405, the arc-shaped positioning block 407 is pushed to rotate inside the fixed sleeve 405 during the sliding process of the connecting sleeve 406, and one end of the arc-shaped positioning block 407 close to the inner wall of the fixed sleeve 405 is abutted against the outer surface of the steel cable, thus completing the positioning of the two groups of steel cables. By starting the electromagnetic ring 408 to drive the magnet block 410 to drive the fixed sleeve 405 to rotate inside the groove of the rotating block 404, the fixed sleeve 405 drives the two groups of steel cables to rotate synchronously during the rotation process, so that the welding machine assembly 2 does not need to adjust the position of the steel cables during the process of comprehensively welding the connections of the two groups of steel cables. By starting the electric telescopic rod 402 to push the fixing plate 403 to move up and down on the upper end of the base 401, and then by starting the motor 409 to drive the rotating block 404 to rotate inside the groove of the fixing plate 403, the clamping assembly 4 can clamp steel cables at different angles during use, so that the device can weld the two groups of steel cables after installation during use, thereby expanding the applicable range of the device.

[0040] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
