Description

Technical Field

[0001] The present invention relates to the technical field of welding tools for elevator cabinet processing, and specifically to a welding tool for elevator cabinet processing. Background Technique

[0002] An elevator is a vertical lift powered by an electric motor, equipped with a box-shaped cabin for carrying passengers or goods in multi-story buildings. The control components of an elevator are usually centrally installed in a cabinet, which is usually composed of side plates, a back plate, a top plate, a bottom plate, and a front door panel. During the processing of the cabinet, it is necessary to weld each plate together to form a closed cabinet with a door panel structure.

[0003] Under the existing technology, welding tools usually need to use fixing parts to fix the side walls of the cabinet body. Since the thickness of the metal plate on the side wall of the cabinet body is relatively thin, when the fixing parts squeeze and clamp the side wall of the cabinet body, the side wall of the cabinet body is prone to deformation under the extrusion of the clamping plate, which will cause welding misalignment between the cabinet body and the cabinet side plate. Summary of the Invention

[0004] The purpose of the present invention is to provide a welding tool for elevator cabinet processing to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a welding tool for elevator cabinet processing, including a tooling base.

The adjusting part is used to adjust the distance between the tooling fixing part and the cabinet; The fixing part is installed on one side of the adjusting part. One end of the fixing part is pressed against the side wall of the cabinet main body, and the fixing part is used to fix the cabinet main body; The auxiliary protection mechanism is installed on the top of the adjusting part. The fixing part drives one side of the auxiliary protection mechanism to be pressed against the inner side of the cabinet main body. The auxiliary protection mechanism is used to cooperate with the fixing part to press, so as to ensure that both the inner and outer sides of the cabinet main body are subjected to clamping forces.

[0007] Furthermore, the adjusting part includes a plurality of adjusting slide rails fixedly connected to the top of the tooling base. A plurality of fixing holes are provided on the adjusting slide rails, and adjusting sliding blocks are slidably connected to both ends of the top of the adjusting slide rails.

[0008] Furthermore, the adjusting part further includes a positioning pin arranged at one end of the adjusting sliding block. The positioning pin can select a suitable fixing hole for pin insertion according to the size of the cabinet, and the positioning pin is used to fix the adjusting part directly above the tooling base. A fixing column is fixedly connected to the top of the adjusting sliding block.

[0009] Furthermore, the fixing part includes a hydraulic cylinder fixedly connected to one side of the fixing column. A hydraulic rod is arranged on the side of the hydraulic cylinder close to the cabinet main body, and a clamping plate is fixedly connected to the end of the hydraulic rod away from the hydraulic cylinder. The clamping plate is used to clamp and fix the outer side wall of the cabinet main body.

[0010] Furthermore, the auxiliary protection mechanism includes an auxiliary slide rail fixedly connected to the top of the fixing column. One side of the top of the clamping plate is fixedly connected with an auxiliary push rod; Wherein, auxiliary sliding blocks are slidably connected to both ends of the auxiliary slide rail. One end of the auxiliary push rod away from the clamping plate is fixedly connected with one end of the auxiliary sliding block, and the clamping plate pushes the auxiliary sliding block at one end of the auxiliary push rod to slide along the auxiliary slide rail.

[0011] Furthermore, the auxiliary protection mechanism further includes a moving rod fixedly connected to one side of the auxiliary sliding block. A plurality of connecting columns are fixedly connected to one side of the moving rod; Wherein, an auxiliary clamping block is fixedly connected to the end of the connecting column away from the moving rod. The auxiliary clamping block corresponds to the clamping plate at one end of the hydraulic rod. A side fixing plate is fixedly connected to the side wall of the auxiliary slide rail, and the side fixing plate is used to fixedly support the cabinet side plate.

[0012] Furthermore, the welding protection part includes: The linkage part is fixedly installed in the middle of the moving rod, and the linkage part is used to connect the sliding effect of the auxiliary sliding block on the auxiliary slide rail; The protection part is installed directly below the auxiliary slide rail. The protection part cooperates with the pushing effect of the linkage part, and the linkage part drives one end of the protection part to be pressed against the weld between the cabinet main body and the cabinet side plate.

[0013] Further, the linkage member includes several rotating rods rotatably connected to the middle of the moving rod. Fixed brackets are fixedly connected to the bottoms of both ends of the auxiliary slide rail, and chutes are provided on the inner sides of both ends of the fixed brackets.

[0014] Further, the protection member includes a sliding column slidably connected inside the chute of the fixed bracket. One end of the rotating rod away from the moving rod is rotatably connected to the middle of the sliding column, and several telescopic rods are fixedly connected to the middle of the sliding column; Among them, a compression spring is sleeved on the end of the telescopic rod away from the sliding column, and a right-angle plate is fixedly connected to the end of the telescopic rod close to the compression spring. When the compression spring is completely compressed, the right-angle surface of the right-angle plate presses against the weld between the cabinet main body and the cabinet side plate.

[0015] The present invention has the following beneficial effects: (1) In the present invention, by providing an auxiliary protection mechanism, when the fixing member fixes the side wall of the cabinet main body, since the thickness of the metal plate on the side wall of the cabinet main body is relatively thin, when the fixing member squeezes and clamps the side wall of the cabinet main body, the side wall of the cabinet main body is prone to deformation under the squeezing action of the clamping plate, which will cause welding misalignment between the cabinet main body and the cabinet side plate. By providing an auxiliary clamping block on the other side of the cabinet main body corresponding to the clamping plate, when the clamping plate squeezes and clamps the outer side wall of the cabinet main body, the auxiliary protection mechanism drives the auxiliary clamping block to simultaneously squeeze the inner side wall of the cabinet main body. This setting makes the inner and outer sides of the side wall of the cabinet main body receive the same squeezing force, thereby improving the clamping stability and avoiding deformation of the cabinet main body due to force.

[0016] (2) In the present invention, by providing an adjusting member, the adjusting slider is pushed to move closer to each other along the adjusting slide rail, and the fixed column drives the cabinet side plate inside the side fixing plate on the auxiliary slide rail to move towards both ends of the cabinet main body. When the side fixing plate pushes the cabinet side plate into both ends of the cabinet main body, the side fixing plate on the auxiliary slide rail is fixed by inserting the positioning pin into the fixing hole. This setting is beneficial for the side fixing plate to support and fix one side of the cabinet side plate. By providing a fixing member, when the positioning pin fixes the adjusting member, the hydraulic cylinder drives the hydraulic rod at one end to move towards the side close to the cabinet main body, and the hydraulic rod drives the clamping plate to clamp and fix the side wall of the cabinet main body, thereby being beneficial to ensuring the stability of welding.

[0017] (3) In the present invention, by providing a welding protection part, when welding the weld between the cabinet main body and the cabinet side plate, since the thicknesses of the cabinet main body and the cabinet side plate are relatively thin, deformation is extremely likely to occur near the weld between the cabinet main body and the cabinet side plate during the welding process. Therefore, when the moving rod inside the auxiliary protection mechanism moves, the linkage member drives the right-angle plate at one end of the protection member to press against the weld corner. On the one hand, it provides clamping stability for the welded parts, and on the other hand, by clamping and fitting the inner right angle of the welded parts, it is beneficial to limit large deformation near the weld of the welded parts.

[0018] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Example 1, please refer to Figures 1-7 As shown, the present invention is a welding tooling for elevator cabinet processing, including a tooling base 1. A plurality of sliding grooves are provided inside the tooling base 1. A lifting push rod 11 is fixedly connected above the tooling base 1. A welding platform 12 is fixedly connected above the lifting push rod 11. The welding platform 12 is slidably connected inside the sliding grooves on the tooling base 1. A plurality of limiting blocks are arranged on the top of the welding platform 12. A cabinet main body 13 is placed on the top of the welding platform 12. A plurality of cabinet side plates 14 are placed directly above the welding platform 12. It further includes: A tooling fixing part 2, which is installed on the top of the tooling base 1. The function of the tooling fixing part 2 is to initially fix the welding parts of the elevator cabinet according to the size of the elevator cabinet; and a welding protection part 3, which is installed directly above the tooling fixing part 2. The tooling fixing part 2 drives the welding protection part 3 to support and fix the welding part of the cabinet welding parts; Among them, the welding protection part 3 supports and fixes the other corner of the weld of the welding part, thereby reducing the deformation generated during the cabinet welding process and improving the cabinet welding quality.

[0024] The tooling fixing part 2 includes: An adjusting part 21, which is installed directly above the tooling base 1. The adjusting part 21 is used to adjust the distance between the tooling fixing part 2 and the cabinet; A fixing part 22, which is installed on one side of the adjusting part 21. One end of the fixing part 22 is pressed against the side wall of the cabinet main body 13. The fixing part 22 is used to fix the cabinet main body 13; An auxiliary protection mechanism 23, which is installed on the top of the adjusting part 21. The fixing part 22 drives one side of the auxiliary protection mechanism 23 to press against the inside of the cabinet main body 13. The auxiliary protection mechanism 23 is used to cooperate with the fixing part 22 to press, so as to ensure that both the inside and outside of the cabinet main body 13 are subjected to clamping forces.

[0025] The adjusting part 21 includes a plurality of adjusting slide rails 211 fixedly connected to the top of the tooling base 1. A plurality of fixing holes 212 are provided on the adjusting slide rails 211. Both ends of the top of the adjusting slide rails 211 are slidably connected with adjusting slide blocks 213.

[0026] The adjusting member 21 further includes a positioning pin 214 provided at one end of the adjusting slider 213. The positioning pin 214 can select a suitable fixing hole 212 for pin insertion according to the size of the cabinet. The positioning pin 214 is used to fix the adjusting member 21 directly above the tooling base 1. A fixing column 215 is fixedly connected to the top of the adjusting slider 213. The function of this component is to push the adjusting slider 213 to approach each other along the adjusting slide rail 211 by setting the adjusting member 21.

[0027] The fixing member 22 includes a hydraulic cylinder 221 fixedly connected to one side of the fixing column 215. A hydraulic rod 222 is provided on the side of the hydraulic cylinder 221 close to the cabinet body 13. The end of the hydraulic rod 222 away from the hydraulic cylinder 221 is fixedly connected to a clamping plate 223. The clamping plate 223 is used to clamp and fix the outer side wall of the cabinet body 13. When the positioning pin 214 fixes the adjusting member 21, the hydraulic cylinder 221 drives the hydraulic rod 222 at one end to move towards the side close to the cabinet body 13, and the hydraulic rod 222 drives the clamping plate 223 to clamp and fix the side wall of the cabinet body 13, which is beneficial to ensuring the stability of welding.

[0028] The auxiliary protection mechanism 23 includes an auxiliary slide rail 231 fixedly connected to the top of the fixing column 215. One side of the top of the clamping plate 223 is fixedly connected to an auxiliary push rod 232; Wherein, both ends of the auxiliary slide rail 231 are slidably connected with auxiliary sliders 233. One end of the auxiliary push rod 232 away from the clamping plate 223 is fixedly connected to one end of the auxiliary slider 233. The clamping plate 223 pushes the auxiliary slider 233 at one end of the auxiliary push rod 232 to slide along the auxiliary slide rail 231.

[0029] The auxiliary protection mechanism 23 further includes a moving rod 234 fixedly connected to one side of the auxiliary slider 233. A plurality of connecting columns 235 are fixedly connected to one side of the moving rod 234; Among them, one end of the connecting column 235 far from the moving rod 234 is fixedly connected with an auxiliary clamping block 236. The auxiliary clamping block 236 corresponds to the clamping plate 223 at one end of the hydraulic rod 222. The side wall of the auxiliary slide rail 231 is fixedly connected with a side fixing plate 237. The side fixing plate 237 is used to fixedly support the side plate 14 of the cabinet. The function of this component is that by setting the auxiliary protection mechanism 23, when the fixing member 22 fixes the side wall of the cabinet main body 13, since the thickness of the metal plate on the side wall of the cabinet main body 13 is relatively thin, when the fixing member 22 squeezes and clamps the side wall of the cabinet main body 13, the side wall of the cabinet main body 13 is prone to deformation under the squeezing action of the clamping plate 223, which will cause the welding dislocation between the cabinet main body 13 and the cabinet side plate 14. By arranging the auxiliary clamping block 236 on the other side of the cabinet main body 13 corresponding to the clamping plate 223, when the hydraulic rod 222 drives the clamping plate 223 to slide towards the side wall of the cabinet main body 13, the clamping plate 223 drives the auxiliary sliding block 233 at one end of the auxiliary push rod 232 to slide along the auxiliary slide rail 231. At this time, the auxiliary sliding block 233 drives the moving rod 234 to move, and the moving rod 234 drives the auxiliary clamping block 236 on the connecting column 235 to clamp the inner wall of the cabinet main body 13; when the clamping plate 223 squeezes and clamps the outer side wall of the cabinet main body 13, the auxiliary protection mechanism 23 drives the auxiliary clamping block 236 to simultaneously squeeze the inner side wall of the cabinet main body 13. Such a setting makes the inner and outer sides of the side wall of the cabinet main body 13 receive the same squeezing force, thereby improving the clamping stability and avoiding the deformation of the cabinet main body 13 due to force.

[0030] Embodiment 2 is different from Embodiment 1 in that; as Figures 1-9 shown, the welding protection part 3 includes: A linkage member 31, which is fixedly installed in the middle of the moving rod 234. The linkage member 31 is used to connect the sliding effect of the auxiliary sliding block 233 on the auxiliary slide rail 231; A protection member 32, which is installed directly below the auxiliary slide rail 231. The protection member 32 cooperates with the pushing effect of the linkage member 31, and the linkage member 31 drives one end of the protection member 32 to squeeze towards the weld between the cabinet main body 13 and the cabinet side plate 14.

[0031] The linkage member 31 includes a plurality of rotating rods 311 rotatably connected to the middle of the moving rod 234. Both ends of the bottom of the auxiliary slide rail 231 are fixedly connected with fixing frames 312, and both ends of the inner side of the fixing frame 312 are provided with sliding grooves 313.

[0032] The protection member 32 includes a sliding column 321 slidably connected inside the sliding groove 313 of the fixing frame 312. One end of the rotating rod 311 far from the moving rod 234 is rotatably connected to the middle of the sliding column 321, and the middle of the sliding column 321 is fixedly connected with a plurality of telescopic rods 322; One end of the telescopic rod 322 away from the sliding column 321 is sleeved with a compression spring 323. One end of the telescopic rod 322 close to the compression spring 323 is fixedly connected with a right-angle plate 324. When the compression spring 323 is completely compressed, the right-angle surface of the right-angle plate 324 presses against the weld between the cabinet main body 13 and the cabinet side plate 14. The function of this component is to set up the welding protection part 3. When welding the weld between the cabinet main body 13 and the cabinet side plate 14, since the thicknesses of the cabinet main body 13 and the cabinet side plate 14 are relatively thin, deformation is extremely likely to occur near the weld between the cabinet main body 13 and the cabinet side plate 14 during the welding process. Therefore, when the moving rod 234 inside the auxiliary protection mechanism 23 moves, the moving rod 234 drives the sliding column 321 at one end of the rotating rod 311 to slide along the chute 313. At this time, the sliding column 321 drives the right-angle plate 324 at one end of the telescopic rod 322 to approach the right-angle weld, and the linkage 31 drives the right-angle plate 324 at one end of the protection part 32 to press against the weld corner. On the one hand, it provides clamping stability for the welded parts, and on the other hand, by clamping and fitting the inner right angle of the welded parts, it is beneficial to limit large deformation near the welds of the welded parts.

[0033] A specific application of this embodiment is as follows: When using the welding tooling for elevator cabinet processing, first place the cabinet body 13 on the limit block at the top of the welding platform 12. At this time, place several cabinet side plates 14 directly above the welding platform 12 along the side fixing plate 237. By setting the adjusting member 21, push the adjusting slider 213 to move closer to each other along the adjusting slide rail 211. The fixing column 215 drives the cabinet side plates 14 inside the side fixing plate 237 on the auxiliary slide rail 231 to move towards both ends of the cabinet body 13. When the side fixing plate 237 pushes the cabinet side plates 14 into both ends of the cabinet body 13, fix the side fixing plate 237 on the auxiliary slide rail 231 by inserting the positioning pin 214 into the fixing hole 212. Such a setting is beneficial for the side fixing plate 237 to support and fix one side of the cabinet side plates 14. By setting the fixing member 22, when the positioning pin 214 fixes the adjusting member 21, the hydraulic cylinder 221 drives the hydraulic rod 222 at one end to move towards the side close to the cabinet body 13. The hydraulic rod 222 drives the clamping plate 223 to clamp and fix the side wall of the cabinet body 13, which is beneficial to ensure the stability of welding. By setting the auxiliary protection mechanism 23, when the fixing member 22 fixes the side wall of the cabinet body 13, since the thickness of the metal plate on the side wall of the cabinet body 13 is relatively thin, when the fixing member 22 squeezes and clamps the side wall of the cabinet body 13, the side wall of the cabinet body 13 is prone to deformation under the extrusion of the clamping plate 223, which will cause welding misalignment between the cabinet body 13 and the cabinet side plates 14. By setting the auxiliary clamping block 236 on the other side of the cabinet body 13 corresponding to the clamping plate 223, when the hydraulic rod 222 drives the clamping plate 223 to slide towards the side wall of the cabinet body 13, the clamping plate 223 drives the auxiliary sliding block 233 at one end of the auxiliary push rod 232 to slide along the auxiliary slide rail 231. At this time, the auxiliary sliding block 233 drives the moving rod 234 to move, and the moving rod 234 drives the auxiliary clamping block 236 on the connecting column 235 to clamp the inner wall of the cabinet body 13. When the clamping plate 223 squeezes and clamps the outer side wall of the cabinet body 13, the auxiliary protection mechanism 23 drives the auxiliary clamping block 236 to simultaneously squeeze the inner side wall of the cabinet body 13. Such a setting makes the inner and outer sides of the side wall of the cabinet body 13 receive the same extrusion force, thus improving the clamping stability while preventing the cabinet body 13 from deforming due to force. By setting the welding protection part 3, when welding the weld between the cabinet main body 13 and the cabinet side plate 14, since the thicknesses of the cabinet main body 13 and the cabinet side plate 14 are relatively thin, deformation is extremely likely to occur near the weld between the cabinet main body 13 and the cabinet side plate 14 during the welding process. Therefore, when the moving rod 234 inside the auxiliary protection mechanism 23 moves, the moving rod 234 drives the sliding column 321 at one end of the rotating rod 311 to slide along the chute 313. At this time, the sliding column 321 drives the right-angle plate 324 at one end of the telescopic rod 322 to approach the right-angle weld, and the linkage 31 drives the right-angle plate 324 at one end of the protection part 32 to squeeze the weld corner. On the one hand, it provides clamping stability for the welded part, and on the other hand, by clamping and fitting the inner right angle of the welded part, it is beneficial to limit large deformation near the weld of the welded part.
