Description

Technical Field

[0001] The invention relates to the technical field of cable protection tube welding, and in particular to a fixing device for cable protection tube welding. Background Art

[0002] The cable protection tube is a kind of tube used to protect the cable from mechanical damage, chemical corrosion, external interference, etc. Its fixing structure during welding is mainly to fix the cable protection tube during the welding process to ensure the quality and stability of the welding. When the commonly used fixing device is used, the clamp fixes the cable protection tube to the welding equipment, and the cable protection tube is clamped to the welding equipment through the clamping device.

[0003] However, when the cable protection tube fixing device is in use, the clamp used for the fixing device cannot adjust the size of the clamp mouth, cannot stably fix workpieces of various sizes, and cannot fix the clamp in the fixing device as needed, so that the clamp cannot be added or adjusted in position. The fixed position of the clamp may cause inaccurate positioning of the workpiece. When the fixing device is in use, the fixed positions on both sides cannot be adjusted as needed, resulting in the need to adjust the welding equipment for coordination. The welding equipment is large, and frequent adjustments to the position and parameters of the welding equipment will increase the wear of the mechanical parts of the equipment and shorten the service life of the equipment.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Reference Figure 4 , 5 8 is a first embodiment of the present invention, which provides a ring mechanism 400, through which the clamp is limited.

[0031] The ring mechanism 400 includes a bottom ring 401, which is arranged on the top of the first fixed frame 202 and the second fixed frame 203. The top of the bottom ring 401 is movably connected to the top ring 402 through a rotating shaft. The front ends of the top ring 402 and the bottom ring 401 are connected by screws. A limit assembly 403 is arranged on the left side of the top ring 402, and two limit assemblies 403 are arranged. Rotating assemblies 404 are arranged on the left and right sides of the inner cavities of the top ring 402 and the bottom ring 401.

[0032] The limiting assembly 403 includes a first blocking plate 403a, the left side of the first blocking plate 403a is movably connected to the second blocking plate 403b through a rotating shaft, the top of the first blocking plate 403a is fixedly connected to the third blocking plate 403c, the inner cavity of the second blocking plate 403b is movably connected to a pressing plate 403d, the pressing plate 403d slides in the inner cavity of the second blocking plate 403b, the right side of the pressing plate 403d passes through the bottom of the right side of the second blocking plate 403b, the left side of the pressing plate 403d is provided with a spring member 403e, the bottom of the first blocking plate 403a is fixedly connected to an insert block 403f, the inner cavity of the insert block 403f is provided with an insert plate 403g, and the left side of the insert plate 403g passes through the left side of the insert block 403f and is fixedly connected to the bottom of the pressing plate 403d.

[0033] The spring member 403e includes a first support spring 403e-1, which is arranged on the left side of the pressing plate 403d. There are eight first support springs 403e-1 and they are evenly distributed. The left side of the first support spring 403e-1 is fixedly connected to the left side of the inner wall of the second blocking plate 403b. The top of the second blocking plate 403b is fixedly connected to the second support spring 403e-2. The right side of the second support spring 403e-2 is fixedly connected to the left side of the third blocking plate 403c.

[0034] Specifically, the bottom ring 401 is arranged on the top of the first fixing frame 202 and the second fixing frame 203, and is movably connected to the top ring 402 through a rotating shaft, and the front end is connected with screws. When it is necessary to fix the cable protection tube, the top ring 402 can be opened, the protection tube can be placed on the bottom ring 401, and then the top ring 402 is closed and fixed with screws.

[0035] Specifically, the spring member 403e on the left side of the push plate 403d provides elastic restoring force for the entire operation. The spring member 403e keeps the push plate 403d in a certain position. At the same time, the plug plate 403g is inserted into the plug block 403f to fix the relative positions of the first blocking plate 403a and the second blocking plate 403b. When adjustment is needed, the push plate 403d can be pressed to release this fixed state.

[0036] Specifically, the first support spring 403e-1 is arranged on the left side of the pressing plate 403d and there are eight of them distributed at equal distances. This design ensures the stable reset of the pressing plate 403d after operation. The second support spring 403e-2 is subjected to force to cause the second blocking plate 403b to rotate, providing elastic support.

[0037] Furthermore, by unscrewing the screws at the front ends of the top ring 402 and the bottom ring 401 , the top ring 402 is opened upward around the rotation axis, and the cable protection tube is placed on the clamp 404 f of the bottom ring 401 .

[0038] Furthermore, when the protective tube is placed on the clamp 404f of the bottom ring 401, it moves to touch the limit assembly 403, and stops moving when the protective tube contacts the pressing plate 403d, ensuring that the protective tubes on both sides are at the center point of the processing table 102 during welding.

[0039] Furthermore, the top ring 402 and the bottom ring 401 are closed by screws, and the press plate is moved in the inner cavity of the second blocking plate 403b, while driving the plug plate 403g to move away from the plug block 403f. At this time, the second support spring 403e-2 applies force to rotate the second blocking plate 403b through the rotating shaft to prevent the limit assembly 403 from affecting the contact of the protective tubes on both sides.

[0040] Reference Figure 6 , 7 9 is a second embodiment of the present invention, which provides a rotating component 404, through which the clamp adjustment effect is achieved.

[0041] The rotating assembly 404 includes a rectangular block 404a, which is arranged in the inner cavity of the top ring 402. The top of the inner cavity of the rectangular block 404a is movably connected to a movable ring 404b through a rotating shaft. A motor component 404c is arranged at the front end of the top of the rectangular block 404a. The top of the movable ring 404b passes through the top of the rectangular block 404a. The inner cavity of the movable ring 404b is movably connected to a threaded rod 404d through a thread. The top and bottom of the threaded rod 404d both pass through the top and bottom of the movable ring 404b. The top of the threaded rod 404d is fixedly connected to a transmission component 404e, and the bottom of the threaded rod 404d is fixedly connected to a clamp 404f.

[0042] The transmission member 404e includes a sleeve 404e-1, which is arranged on the top of the threaded rod 404d. A movable rod 404e-2 is arranged in the inner cavity of the sleeve 404e-1 and on the side away from the threaded rod 404d. The surface of the movable rod 404e-2 is slidably connected to the inner cavity of the sleeve 404e-1, the bottom of the movable rod 404e-2 is fixedly connected to the top of the rectangular block 404a, and a limiting rod 404e-3 is fixedly connected to the side of the sleeve 404e-1 away from the movable rod 404e-2. Limiting grooves 404e-4 are provided in the inner cavities of the bottom ring 401 and the top ring 402 at the positions corresponding to the limiting rod 404e-3.

[0043] The clamp 404f includes a clamp plate 404f-1, and the left and right sides of the bottom of the clamp plate 404f-1 are movably connected to a rotating block 404f-2 through a rotating shaft. A triangular clamp wheel 404f-3 is arranged at the bottom of the rotating block 404f-2, and a guide member 404f-4 is arranged on the left and right sides of the rotating block 404f-2.

[0044] The guide member 404f-4 includes a first guide gear 404f-4a, which is arranged on the left side of the rotating block 404f-2. A first metal plate 404f-4b is arranged on the right side of the surface of the first guide gear 404f-4a. A second guide gear 404f-4c is arranged in the inner cavity of the first metal plate 404f-4b. The top and bottom of the second guide gear 404f-4c both penetrate the top and bottom of the first metal plate 404f-4b. The right side of the second guide gear 404f-4c is meshed and connected with the top of the first guide gear 404f-4a. A telescopic rod 404f-4d is arranged on the top of the second guide gear 404f-4c. The top of the telescopic rod 404f-4d is fixedly connected with the third guide gear 404f-4e. The second guide gear 404f-4c A second metal plate 404f-4f is provided at the bottom of the surface, and a fourth guide gear 404f-4g is provided in the inner cavity of the second metal plate 404f-4f. The bottom of the fourth guide gear 404f-4g is meshingly connected with the right side of the third guide gear 404f-4e. A circular block 404f-4h is fixedly connected to the right side of the fourth guide gear 404f-4g, and a metal gear 404f-4i is fixedly connected to the inner side of the circular block 404f-4h. A support block 404f-4j is movably sleeved on the surface of the circular block 404f-4h, and the top of the support block 404f-4j is fixedly connected to the bottom of the rectangular block 404a. Metal tooth plates 404f-4k are provided at the front and back ends of the threaded rod 404d, and the front end of the metal tooth plate 404f-4k is meshingly connected with the back end of the metal gear 404f-4i.

[0045] Specifically, the clamp 404f fixedly connected to the bottom of the threaded rod 404d is a key part that directly contacts the cable protection tube and realizes the clamping function. Through the above-mentioned power transmission, motion conversion and guide limit mechanism, the clamp 404f can accurately approach and clamp the cable protection tube under the drive of the threaded rod 404d.

[0046] Specifically, the cooperation between the sliding sleeve 404e-1 and the movable rod 404e-2 provides a stable guide for the linear motion of the threaded rod 404d. The sliding sleeve 404e-1 can slide on the surface of the movable rod 404e-2, limiting the sliding sleeve 404e-1 and the threaded rod 404d connected thereto to move only along the axial direction of the movable rod 404e-2, avoiding unnecessary swinging or deviation of the threaded rod 404d during the operation of the rotating assembly 404, and ensuring the linearity and accuracy of the up and down movement of the clamp 404f.

[0047] Specifically, when the clamp 404f is close to the cable protection tube, the clamp plate 404f-1 can be adjusted to a certain extent according to the diameter of the protection tube. The guide members 404f-4 arranged on both sides of the rotating block 404f-2 provide guidance for the movement of the clamp 404f. During the clamping and releasing operations, the guide members 404f-4 can ensure that the rotating block 404f-2 and the clamp plate 404f-1 and the triangular clamp wheel 404f-3 connected thereto move according to the predetermined trajectory.

[0048] Specifically, the first guide gear 404f-4a is arranged on the left side of the rotating block 404f-2 and is meshed with the second guide gear 404f-4c. When the rotating block 404f-2 rotates, it drives the first guide gear 404f-4a to rotate, thereby driving the second guide gear 404f-4c to rotate. The third guide gear 404f-4e at the top of the telescopic rod 404f-4d is meshed with the fourth guide gear 404f-4g to continue to transmit motion. The fourth guide gear 404f-4g in the second metal plate 404f-4f at the bottom of the second guide gear 404f-4c is also stably supported and positioned, ensuring the precise transmission of motion and avoiding errors caused by friction or sliding, so that the movement of the clamp 404f can be precisely controlled.

[0049] Furthermore, the servo motor 404c-1 at the top of the rectangular block 404a is started, and the output end of the servo motor 404c-1 drives the first motor gear 404c-2 to rotate, and the first motor gear 404c-2 is meshed with the second motor gear 404c-3, thereby rotating the movable ring 404b. Since the movable ring 404b is movably connected to the threaded rod 404d through threads, the rotation of the movable ring 404b causes the threaded rod 404d to move up and down.

[0050] Furthermore, when the threaded rod 404d moves, it will drive the sliding sleeve 404e-1 and the limiting rod 404e-3 to move. When clamping is required, the threaded rod 404d moves inward and drives the limiting rod 404e-3 to move inward. When the protrusion of the limiting rod 404e-3 moves to the inner cavity of the bottom ring 401 and the top ring 402, the position of the rectangular block 404a will be fixed to prevent it from sliding.

[0051] Furthermore, the triangular clamping wheels 404f-3 on both sides of the bottom of the clamping plate 404f-1 first contact the object. Since the rotating block 404f-2 is movably connected to the clamping plate 404f-1 through the rotating shaft, the triangular clamping wheels 404f-3 can be rotated and adjusted to a certain extent according to the rotating block 404f-2 to better adapt to the surface of the object, increase the contact area and the stability of the clamping.

[0052] Furthermore, the gears and components in the guide member 404f-4 work in coordination, starting with the first guide gear 404f-4a, which rotates and transmits motion through meshing with the second guide gear 404f-4c in the first metal plate 404f-4b, and the second guide gear 404f-4c drives the third guide gear 404f-4e on the telescopic rod 404f-4d to rotate, and the third guide gear 404f-4e meshes with the fourth guide gear 404f-4g in the second metal plate 404f-4f, and the fourth guide gear 404f- 4g drives the circular block 404f-4h and the metal gear 404f-4i inside it to rotate, and the metal gear 404f-4i engages with the metal tooth plates 404f-4k at the front and back ends of the threaded rod 404d, ensuring that the clamp 404f is subjected to uniform and stable force in all directions during the clamping process. When the threaded rod 404d is clamped inwardly, the triangular clamp wheel 404f-3 in the clamp 404f will shrink through the rotation of the rotating block 404f-2, which is convenient for fixing protective tubes of different diameters and facilitating welding operations.

[0053] The remaining structures are the same as those of Example 1.

[0054] Reference Figures 1 to 9 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: this embodiment provides a fixing device for welding a cable protection tube.

[0055] Start the motor on the top of the processing table 102 to drive the control gear 301 to rotate. Since the control tooth plate 302 is meshed with the control gear 301 and the control tooth plate 302 is fixed to the slide plate 104, the rotation of the control gear 301 drives the control tooth plate 302 to slide along the sliding plate 103, thereby causing the slide plate 104 to slide on the sliding plate 103. According to the length of the cable protection tube, the distance between the two slide plates 104 is adjusted so that the fixed plate 201 is in a suitable position for subsequent fixing of the cable protection tube. The cylinder 204 is extended or shortened to push the second fixed frame 203 to slide on the top of the fixed plate 201, thereby adjusting the distance between the first fixed frame 202 and the second fixed frame 203 to facilitate the fixing of the protection tube.

[0056] By unscrewing the screws at the front ends of the top ring 402 and the bottom ring 401 , the top ring 402 is opened upward around the rotation axis, and the cable protection tube is placed on the clamp 404 f of the bottom ring 401 .

[0057] When the protective tube is placed on the clamp 404f of the bottom ring 401, it moves and touches the limit assembly 403. When the protective tube moves and contacts with the pressing plate 403d, it stops moving, ensuring that the protective tubes on both sides are at the center point of the processing table 102 during welding. Then the top ring 402 and the bottom ring 401 are closed by screws, and the pressing plate 403d is moved in the inner cavity of the second blocking plate 403b, while driving the plug plate 403g to move away from the plug block 403f. At this time, the second support spring 403e-2 applies force to rotate the second blocking plate 403b through the rotating shaft to prevent the limit assembly 403 from affecting the contact of the protective tubes on both sides.

[0058] The servo motor 404c-1 on the top of the rectangular block 404a is started, and the output end of the servo motor 404c-1 drives the first motor gear 404c-2 to rotate, and the first motor gear 404c-2 is meshed with the second motor gear 404c-3, so that the movable ring 404b rotates. Since the movable ring 404b is movably connected to the threaded rod 404d through a thread, the rotation of the movable ring 404b causes the threaded rod 404d to move up and down. When the threaded rod 404d moves, the transmission member 404e on the top of the threaded rod plays a guiding and limiting role. The sliding sleeve 404e-1 slides on the movable rod 404e-2, and the limiting rod 404e-3 slides in the limiting groove 404e-4 of the inner cavity of the bottom ring 401 and the top ring 402, ensuring that the threaded rod 404d can only move up and down. The clamp 404f at the bottom of the threaded rod 404d moves close to the cable protection tube as the threaded rod 404d moves, and the clamp 404f-1 contacts the cable protection tube through the rotating block 404f-2 and the triangular clamp wheel 404f-3. At the same time, the various gears and components in the guide member 404f-4 cooperate with each other. The first guide gear 404f-4a is used as the starting point, and its rotation is transmitted through meshing with the second guide gear 404f-4c in the first metal plate 404f-4b. The second guide gear 404f-4c drives the third guide gear 404f-4e on the telescopic rod 404f-4d to rotate, and the third guide gear 404f-4e meshes with the fourth guide gear 404f-4g in the second metal plate 404f-4f. The fourth guide gear 404f-4g drives the circular block 404f- 4h and the metal gears 404f-4i inside thereof rotate, and the metal gears 404f-4i mesh with the metal tooth plates 404f-4k at the front and back ends of the threaded rod 404d, ensuring that the clamp 404f is subjected to uniform and stable force in all directions during the clamping process. When the threaded rod 404d is clamped inwardly, the triangular clamp wheel 404f-3 in the clamp 404f will shrink through the rotation of the rotating block 404f-2, so as to facilitate the fixation of protective tubes of different diameters and facilitate the welding operation.

[0059] When the threaded rod 404d moves, it will drive the sliding sleeve 404e-1 and the limit rod 404e-3 to move. When clamping is required, the threaded rod 404d moves inward, and at the same time drives the limit rod 404e-3 to move inward. When the protrusion of the limit rod 404e-3 moves to the inner cavity of the bottom ring 401 and the top ring 402, the position of the rectangular block 404a will be fixed to prevent it from sliding. When it is necessary to add a clamp, it can be installed through the opening at the front end of the bottom ring 401 and the top ring 402.

[0060] After the welding is completed, the threaded rod 404d is first raised by the servo motor 404c-1, the clamp 404f for the cable protection tube is loosened, the limit assembly 403 is opened, the screws at the front end of the top ring 402 and the bottom ring 401 are unscrewed, and the top ring 402 is opened to take out the cable protection tube.

[0061] In summary, when the cable protection tube fixing device is used, the size of the clamp's clamping mouth can be adjusted to stably fix workpieces of various sizes. The clamp can be fixed in the fixing device as needed, so that the number of clamps can be increased. The clamp position can be adjusted in Tonghua City, and when the fixing device is used, the fixed positions on both sides can be adjusted as needed to avoid frequent adjustments to the position of the welding equipment.
