A welding fixture for processing elevator cabinets

Abstract

This invention relates to the field of welding fixture technology for elevator cabinet processing, and discloses a welding fixture for elevator cabinet processing, including a fixture base with several sliding grooves on the inner side of the fixture base. In this invention, when the fixing component secures the side wall of the cabinet body, the side wall of the cabinet body is relatively thin. When the fixing component clamps the side wall of the cabinet body, the side wall is prone to deformation under the pressure of the clamping plate. This can lead to welding misalignment between the cabinet body and the side plate. By setting an auxiliary clamping block on the other side of the cabinet body corresponding to the clamping plate, when the clamping plate clamps the outer side wall of the cabinet body, the auxiliary protective mechanism drives the auxiliary clamping block to simultaneously clamp the inner side wall of the cabinet body. This arrangement ensures that the inner and outer sides of the side wall of the cabinet body are subjected to the same compressive force, thereby improving clamping stability while preventing deformation of the cabinet body under stress.

Description

Technical Field

[0001] This invention relates to the field of welding fixtures for elevator cabinet processing, specifically a welding fixture for elevator cabinet processing. Background Technology

[0002] An elevator is a vertical lifting machine powered by an electric motor, equipped with a box-shaped cabin, used for transporting people or goods in multi-story buildings. The control components of an elevator are usually installed in a cabinet, which typically consists of side panels, back panels, top panels, bottom panels, and a front door panel. During the cabinet manufacturing process, the various panels need to be welded together to form a closed cabinet with a door panel structure.

[0003] Under current technology, welding fixtures typically require the use of fasteners to fix the side walls of the cabinet body. Since the metal plates of the side walls of the cabinet body are relatively thin, when the fasteners squeeze and clamp the side walls of the cabinet body, the side walls of the cabinet body are prone to deformation under the squeezing action of the clamping plates. This can lead to misalignment of the welding between the cabinet body and the side panels. Summary of the Invention

[0004] The purpose of this invention is to provide a welding fixture for processing elevator cabinets, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a welding fixture for processing elevator cabinets, comprising a fixture base with several sliding grooves on its inner side. A lifting push rod is fixedly connected to the top of the fixture base, and a welding platform is fixedly connected to the top of the lifting push rod. The welding platform is slidably connected to the sliding grooves on the fixture base. Several limiting blocks are provided on the top of the welding platform. The main body of the cabinet is placed on the top of the welding platform, and several cabinet side panels are placed directly above the welding platform. The invention also includes:

[0007] The tooling fixing part is installed on the top of the tooling base. The function of the tooling fixing part is to initially fix the welded parts of the elevator cabinet according to the size of the elevator cabinet. The welding protection part is installed directly above the tooling fixing part. The tooling fixing part drives the welding protection part to support and fix the welded parts of the cabinet.

[0008] The welding protection section supports and fixes the corner of the weld seam on the other side of the welded part, thereby reducing the deformation generated during the cabinet welding process and improving the welding quality of the cabinet.

[0009] Furthermore, the tooling fixing part includes:

[0010] Adjustment component, installed directly above the fixture base, is used to adjust the distance between the fixture fixing part and the cabinet;

[0011] The fastener is installed on one side of the adjusting component. One end of the fastener is pressed against the side wall of the main body of the cabinet. The fastener is used to fix the main body of the cabinet.

[0012] The auxiliary protection mechanism is installed on the top of the adjusting component. The fixing component drives one side of the auxiliary protection mechanism to press against the inside of the cabinet body. The auxiliary protection mechanism is used to cooperate with the pressing of the fixing component to ensure that both the inner and outer sides of the cabinet body are clamped.

[0013] Furthermore, the adjusting component includes several adjusting slide rails fixedly connected to the top of the tooling base, several 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.

[0014] Furthermore, the adjusting component also includes a positioning pin at one end of the adjusting sliding block. The positioning pin can be inserted into a suitable fixing hole according to the size of the cabinet. The positioning pin is used to fix the adjusting component directly above the tooling base. A fixing post is fixedly connected to the top of the adjusting sliding block.

[0015] Furthermore, the fastener includes a hydraulic cylinder fixedly connected to one side of the fixing column. A hydraulic rod is provided on the side of the hydraulic cylinder closer to the main body of the cabinet. 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 wall of the main body of the cabinet.

[0016] Furthermore, the auxiliary protection mechanism includes an auxiliary slide rail fixedly connected to the top of the fixed column, and an auxiliary push rod fixedly connected to one side of the top of the clamping plate;

[0017] Both ends of the auxiliary slide rail are slidably connected to auxiliary sliding blocks. The end of the auxiliary push rod away from the clamp is fixedly connected to the end of the auxiliary sliding block. The clamp pushes the auxiliary sliding block at one end of the auxiliary push rod to slide along the auxiliary slide rail.

[0018] Furthermore, the auxiliary protection mechanism also includes a movable rod fixedly connected to one side of the auxiliary sliding block, and several connecting posts are fixedly connected to one side of the movable rod;

[0019] Among them, the end of the connecting column away from the moving rod is fixedly connected to an auxiliary clamping block, which corresponds to the clamping plate at one end of the hydraulic rod. The side wall of the auxiliary slide rail is fixedly connected to a side fixing plate, which is used to fix and support the side panel of the cabinet.

[0020] Furthermore, the welding protection part includes:

[0021] Linkage component, fixedly installed in the middle of the moving rod, is used to connect the sliding effect of the auxiliary sliding block on the auxiliary slide rail;

[0022] The protective component is installed directly below the auxiliary slide rail. The protective component works in conjunction with the pushing effect of the linkage component, which causes one end of the protective component to be pressed against the weld between the main body of the cabinet and the side panel of the cabinet.

[0023] Furthermore, the linkage includes several rotating rods rotatably connected to the middle of the moving rod, and fixed frames are fixedly connected to the bottom of both ends of the auxiliary slide rail, with slide grooves opened on the inner sides of both ends of the fixed frames.

[0024] Furthermore, the protective component includes a sliding column that is slidably connected inside the slide groove on the fixed frame, and the end of the rotating rod away from the moving rod is rotatably connected to the middle of the sliding column. Several telescopic rods are fixedly connected to the middle of the sliding column.

[0025] The telescopic rod is fitted with a pressure spring at the end away from the sliding column, and a right-angle plate is fixedly connected to the end of the telescopic rod near the pressure spring. When the pressure spring is fully compressed, the right-angled surface of the right-angle plate is pressed against the weld between the main body of the cabinet and the side panel of the cabinet.

[0026] The present invention has the following beneficial effects:

[0027] (1) In this invention, by setting an auxiliary protective mechanism, when the fixing member fixes the side wall of the cabinet body, the side wall of the cabinet body is easily deformed under the squeezing action of the clamping plate when the fixing member squeezes and clamps the side wall of the cabinet body. This will cause the welding between the cabinet body and the cabinet side plate to be misaligned. By setting an auxiliary clamping block on the other side of the cabinet body corresponding to the clamping plate, when the clamping plate squeezes and clamps the outer side wall of the cabinet body, the auxiliary protective mechanism drives the auxiliary clamping block to squeeze the inner side wall of the cabinet body at the same time. This setting makes the inner and outer sides of the cabinet body subject to the same squeezing force, thereby improving the clamping stability while avoiding deformation of the cabinet body under force.

[0028] (2) In this invention, by setting an adjusting component, the adjusting sliding block is pushed closer to each other along the adjusting slide rail. 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 body. When the side fixing plate pushes the cabinet side plate into both ends of the cabinet body, the side fixing plate on the auxiliary slide rail is fixed by inserting the positioning pin into the fixing hole. This setting is conducive to the side fixing plate supporting and fixing one side of the cabinet side plate. By setting a fixing component, when the positioning pin fixes the adjusting component, the hydraulic cylinder drives the hydraulic rod at one end to move towards the side closer to the cabinet body. The hydraulic rod drives the clamping plate to clamp and fix the side wall of the cabinet body, which is conducive to ensuring the stability of welding.

[0029] (3) In this invention, by setting a welding protection part, when welding the weld between the cabinet body and the cabinet side plate, since the thickness of the cabinet body and the cabinet side plate is relatively thin, deformation is very likely to occur near the weld between the cabinet body and the cabinet side plate during the welding process. Therefore, when the moving rod inside the auxiliary protection mechanism moves, the linkage drives the right-angle plate at one end of the protection part to press against 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 helps to limit the large deformation near the weld of the welded part.

[0030] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1, please refer to Figures 1-7 As shown, the present invention is a welding fixture for processing elevator cabinets, including a fixture base 1. The fixture base 1 has several sliding grooves on its inner side. A lifting push rod 11 is fixedly connected to the top of the fixture base 1. A welding platform 12 is fixedly connected to the top of the lifting push rod 11. The welding platform 12 is slidably connected to the sliding grooves on the fixture base 1. Several limiting blocks are provided on the top of the welding platform 12. A cabinet body 13 is placed on the top of the welding platform 12. Several cabinet side plates 14 are placed directly above the welding platform 12. The invention also includes:

[0045] The tooling fixing part 2 is installed on the top of the tooling base 1. The function of the tooling fixing part 2 is to initially fix the welded parts of the elevator cabinet according to the size of the elevator cabinet; and the welding protection part 3 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 welded parts of the cabinet.

[0046] Among them, the welding protection part 3 supports and fixes the corner of the weld seam on the other side of the welded part, thereby reducing the deformation generated during the cabinet welding process and improving the welding quality of the cabinet.

[0047] Tooling fixing part 2 includes:

[0048] Adjustment component 21 is installed directly above the tooling base 1. Adjustment component 21 is used to adjust the distance between the tooling fixing part 2 and the cabinet.

[0049] The fastener 22 is installed on one side of the adjusting member 21. One end of the fastener 22 is pressed against the side wall of the cabinet body 13. The fastener 22 is used to fix the cabinet body 13.

[0050] The auxiliary protection mechanism 23 is installed on the top of the adjusting member 21. The fixing member 22 drives one side of the auxiliary protection mechanism 23 to press against the inside of the cabinet body 13. The auxiliary protection mechanism 23 is used to cooperate with the fixing member 22 to press, thereby ensuring that both the inner and outer sides of the cabinet body 13 are subjected to clamping force.

[0051] The adjusting component 21 includes several adjusting slide rails 211 fixedly connected to the top of the tooling base 1. Several fixing holes 212 are provided on the adjusting slide rails 211. Adjusting sliding blocks 213 are slidably connected to both ends of the top of the adjusting slide rails 211.

[0052] The adjusting component 21 also includes a positioning pin 214 disposed at one end of the adjusting sliding block 213. The positioning pin 214 can be inserted into a suitable fixing hole 212 according to the size of the cabinet. The positioning pin 214 is used to fix the adjusting component 21 directly above the tooling base 1. The top of the adjusting sliding block 213 is fixedly connected to a fixing post 215. The function of this component is to push the adjusting sliding block 213 closer to each other along the adjusting slide rail 211 by setting the adjusting component 21.

[0053] The fastener 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 near the cabinet body 13. A clamping plate 223 is fixedly connected to the end of the hydraulic rod 222 away from the hydraulic cylinder 221. The clamping plate 223 is used to clamp and fix the outer wall of the cabinet body 13. When the positioning pin 214 fixes the adjusting component 21, the hydraulic cylinder 221 drives the hydraulic rod 222 at one end to move towards the side near 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 helps to ensure the stability of welding.

[0054] The auxiliary protection mechanism 23 includes an auxiliary slide rail 231 fixedly connected to the top of the fixed column 215, and an auxiliary push rod 232 fixedly connected to one side of the top of the clamping plate 223.

[0055] In this system, auxiliary sliding blocks 233 are slidably connected to both ends of the auxiliary slide rail 231, and the end of the auxiliary push rod 232 away from the clamping plate 223 is fixedly connected to the end of the auxiliary sliding block 233. The clamping plate 223 pushes the auxiliary sliding block 233 at one end of the auxiliary push rod 232 to slide along the auxiliary slide rail 231.

[0056] The auxiliary protection mechanism 23 also includes a movable rod 234 fixedly connected to one side of the auxiliary sliding block 233, and a number of connecting posts 235 are fixedly connected to one side of the movable rod 234;

[0057] Among them, an auxiliary clamping block 236 is fixedly connected to the end of the connecting column 235 away from the moving rod 234. The auxiliary clamping block 236 corresponds to the clamping plate 223 at one end of the hydraulic rod 222. A side fixing plate 237 is fixedly connected to the side wall of the auxiliary slide rail 231. The side fixing plate 237 is used to fix and support the side panel 14 of the cabinet. The function of this component is to set an auxiliary protection mechanism 23. When the fixing member 22 fixes the side wall of the cabinet body 13, because the metal plate of 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 squeezing action of the clamping plate 223. This will cause the welding between the cabinet body 13 and the side panel 14 to be misaligned. An auxiliary clamping block 236 is provided on the other side of the cabinet body 13. When the hydraulic rod 222 drives the clamping plate 223 to slide closer to 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, along with the auxiliary clamping block 236 on the connecting column 235, clamps the inner wall of the cabinet body 13. When the clamping plate 223 squeezes and clamps the outer wall of the cabinet body 13, the auxiliary protection mechanism 23 drives the auxiliary clamping block 236 to squeeze the inner wall of the cabinet body 13 at the same time. This arrangement makes the inner and outer sides of the cabinet body 13 subjected to the same squeezing force, thereby improving the clamping stability and preventing the cabinet body 13 from deforming under force.

[0058] Example 2 differs from Example 1 in that: Figures 1-9 As shown, the welding protection part 3 includes:

[0059] Linkage component 31 is fixedly installed in the middle of the moving rod 234. Linkage component 31 is used to connect the sliding effect of the auxiliary sliding block 233 on the auxiliary slide rail 231.

[0060] The protective component 32 is installed directly below the auxiliary slide rail 231. The protective component 32 works in conjunction with the pushing effect of the linkage component 31. The linkage component 31 drives one end of the protective component 32 to be pressed against the weld between the cabinet body 13 and the cabinet side plate 14.

[0061] The linkage 31 includes several rotating rods 311 rotatably connected to the middle of the moving rod 234. The bottom of both ends of the auxiliary slide rail 231 are fixedly connected to the fixing frame 312, and the inner side of both ends of the fixing frame 312 is provided with a slide groove 313.

[0062] The protective component 32 includes a sliding column 321 that is slidably connected to the inside of the slide groove 313 on the fixed frame 312. The end of the rotating rod 311 away from the moving rod 234 is rotatably connected to the middle of the sliding column 321. Several telescopic rods 322 are fixedly connected to the middle of the sliding column 321.

[0063] The telescopic rod 322 has a pressure spring 323 fitted at the end away from the sliding column 321, and a right-angle plate 324 is fixedly connected to the end of the telescopic rod 322 near the pressure spring 323. When the pressure spring 323 is fully compressed, the right-angle surface of the right-angle plate 324 is pressed against the weld between the cabinet body 13 and the cabinet side panel 14. The function of this component is to provide a weld protection part 3 so that when welding the weld between the cabinet body 13 and the cabinet side panel 14, the thickness of the cabinet body 13 and the cabinet side panel 14 is relatively thin, so the weld between the cabinet body 13 and the cabinet side panel 14 is not compressed during the welding process. The weld seam between the cabinet side panels 14 is prone to deformation. 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 slide groove 313. At this time, the sliding column 321 drives the right-angle plate 324 at one end of the telescopic rod 322 to move closer to the right-angle weld seam. The linkage 31 drives the right-angle plate 324 at one end of the protective component 32 to press against the weld seam corner. On the one hand, it provides clamping stability for the welded parts. On the other hand, by clamping and fitting the inner right angle of the welded parts, it helps to limit the large deformation near the weld seam of the welded parts.

[0064] One specific application of this embodiment is:

[0065] When using the welding fixture for processing the elevator cabinet, first place the cabinet body 13 on the limiting block at the top of the welding platform 12. Then, place several cabinet side panels 14 along the side fixing plate 237 directly above the welding platform 12. By setting the adjusting component 21, push the adjusting sliding block 213 closer to each other along the adjusting slide rail 211. The fixing column 215 drives the cabinet side panels 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 panels 14 into both ends of the cabinet body 13, the... The positioning pin 214 is inserted into the fixing hole 212 to fix the side fixing plate 237 on the auxiliary slide rail 231. This arrangement helps the side fixing plate 237 to support and fix one side of the cabinet side plate 14. By setting the fixing component 22, when the positioning pin 214 fixes the adjusting component 21, the hydraulic cylinder 221 drives the hydraulic rod 222 at one end to move closer 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, thereby helping to ensure the stability of welding. By setting the auxiliary protection mechanism 23, when the fixing... When component 22 is used to fix the side wall of the cabinet body 13, the side wall metal plate of the cabinet body 13 is relatively thin. When the fixing component 22 clamps the side wall of the cabinet body 13, the side wall of the cabinet body 13 is prone to deformation under the pressure of the clamping plate 223. This can lead to misalignment between the welding of the cabinet body 13 and the cabinet side plate 14. By setting an 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 closer to the side wall of the cabinet body 13, the clamping plate 223 drives one end of the auxiliary push rod 232. The auxiliary sliding block 233 slides along the auxiliary slide rail 231. At this time, the auxiliary sliding block 233 drives the moving rod 234 to move. The moving rod 234, along with the auxiliary clamping block 236 on the connecting column 235, clamps the inner wall of the cabinet body 13. When the clamping plate 223 squeezes and clamps the outer wall of the cabinet body 13, the auxiliary protection mechanism 23 drives the auxiliary clamping block 236 to squeeze the inner wall of the cabinet body 13 at the same time. This arrangement makes the inner and outer sides of the cabinet body 13 subjected to the same squeezing force, thereby improving the clamping stability while preventing the cabinet body 13 from deforming under force.

[0066] By setting up the welding protection part 3, when welding the weld between the cabinet body 13 and the cabinet side plate 14, since the thickness of the cabinet body 13 and the cabinet side plate 14 is relatively thin, deformation is very likely to occur near the weld between the cabinet 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 slide groove 313. At this time, the sliding column 321 drives the right angle plate 324 at one end of the telescopic rod 322 to move closer to the right angle weld. 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 helps to limit the large deformation near the weld of the welded parts.
