Description

Technical Field

[0001] The present invention relates to the field of elevator plate welding equipment, and specifically to a welding device for elevator plates. Background Art

[0002] An elevator refers to a device that serves several floors in a building. A vertical elevator has a car, and the size and structure of the car are convenient for passengers to enter and exit or for loading and unloading goods. Regardless of its driving method, an elevator is generally referred to as a vertical transportation tool in a building. During the production process of an elevator car, elevator stainless steel plates are required. Some elevator stainless steel plates have small size specifications, and they need to be welded together with another elevator stainless steel plate to form a whole qualified plate for use, thus avoiding material waste.

[0003] However, the length of the elevator stainless steel plates to be welded is relatively large, so that the existing welding equipment cannot conveniently and effectively align the long edge parts of the two plates to be welded, resulting in uneven sizes of the welding gaps at various parts. At the same time, impurities adhere to the edge parts of the plates to be welded, which is inconvenient to clean and is not conducive to improving the welding quality. Therefore, a welding device for elevator plates is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a welding device for elevator plates in order to solve the above problems.

[0005] The present invention realizes the above purpose through the following technical solutions. A welding device for elevator plates includes an electric welding machine, an internal tooth belt, several edge processing mechanisms distributed and connected to the internal tooth belt, a driving gear, a table board, a linear motor, a ceramic side pressing block, and a U-shaped hanging seat. Two welding torch heads connected to the electric welding machine are respectively installed at the end parts of the output ends of two first oil cylinders, and a U-shaped hanging seat is installed at the output end of the first oil cylinder located between the two second oil cylinders. A short shaft is installed at the convex part in the middle of the ceramic side pressing block, and one end of the short shaft is connected to a reduction motor located on one side of the U-shaped hanging seat. The bottom of the ceramic side pressing block contacts the corresponding edge processing mechanism through movement;

[0006] The edge processing mechanism includes a cleaning disc, a slider, a U-shaped support, a side guide hole, and a spring. The middle part of the cleaning disc is rotatably installed between the two sliders, and the two sliders are respectively slidably connected to the side guide holes on both sides of the U-shaped support. The bottom of the slider is connected to the inner bottom end of the side guide hole through a spring. The bottom of the U-shaped support is fixedly connected to the corresponding part of the internal tooth belt. The cleaning disc partially extends beyond the welding station strip hole, and the welding station strip hole is opened in the middle of the table board;

[0007] The tooth surface on the inner side of the internal tooth belt is in meshing transmission connection with four driving gears distributed in a matrix, and the four driving gears are respectively rotatably installed at the four corners of the gear carrier. A servo motor is installed at one of the corners of the gear carrier, and the servo motor is connected to the shaft end on one side of a driving gear. Both ends of the gear carrier are respectively installed on the inner side walls of both sides in the table bracket.

[0008] Preferably, the cylinder body ends of the first oil cylinder and the second oil cylinder are both fixedly connected to the bottom of the pulling connecting piece located on the linear motor, and both sides of the pulling connecting piece are fixedly connected to the bottom of the electric welding machine through a connecting structure.

[0009] Preferably, the linear motor is installed on the inner top wall of the U-shaped hanging plate, and both ends of the U-shaped hanging plate are respectively installed at both ends of the top of the table bracket. There is a spacing between the top surface of the U-shaped hanging plate and the bottom of the electric welding machine.

[0010] Preferably, partial surfaces on both sides of the cleaning disc are respectively in contact with the side surfaces of the edges of two plates to be welded, and the weld spacing dimension between the edges of the two plates to be welded is greater than the width dimension of the ceramic side pressing strip.

[0011] Preferably, side strip plates are installed on both sides of the bottom orifice of the welding station strip hole, and supporting gears are rotatably installed between the two side strip plates. Each supporting gear is in meshing transmission connection with the corresponding tooth surface on the inner side of the internal tooth belt.

[0012] Preferably, the table board is installed on the top of the table bracket, and edge grooves are distributed on the front and rear parts of the surface of the table board.

[0013] Preferably, a carrier block is slidably installed in the edge groove, an electromagnet is inlaid on the surface of the carrier block, and one side of the carrier block is connected to the output end of a push-pull air cylinder connected to the outer end of the edge groove.

[0014] Preferably, a strip-shaped protective cover is installed at the bottom of the gear carrier, and the internal tooth belt and the edge treatment mechanism connected to the internal tooth belt are surrounded inside the strip-shaped protective cover.

[0015] The beneficial effects of the present invention are:

[0016] First, using the part of the cleaning disc that extends beyond the welding station strip hole as an alignment and stopping structure, and combining multiple cleaning discs on the same straight line, ensures the neatness of the two plates to be welded when forming a weld joint.

[0017] II. The internal tooth belt connected by meshing transmission and the connected opposite side processing mechanism are in a high-speed operation state, achieving the effect of moving each cleaning disc in the internal tooth belt to the gap formed between the opposite sides of the two plates to be welded. The side wall of the cleaning disc can be used to clean the impurities on the corresponding side wall of the plate to be welded, ensuring the cleanliness of the welding part, which helps to improve the welding quality and enhance the welding strength.

[0018] III. The ceramic side pressing strip blocks can be rotated sideways to press the cleaning disc into the U-shaped support under the action of the spring, and combined with the synchronous movement of the ceramic side pressing strip blocks and the welding torch head, it is beneficial to orderly move the cleaning disc away from between the two plates to be welded, providing an unobstructed welding environment for the movement and welding of the welding torch head.

[0019] IV. The distributed supporting gears play a role in supporting the corresponding parts of the internal tooth belt, and at the same time can prevent the internal tooth belt at this part from sagging, ensuring the stability of the position movement of the cleaning disc.

[0029] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below 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 making creative efforts shall fall within the protection scope of the present invention.

[0030] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0032] Please refer to Figure 1-7As shown in the figure, a welding device for elevator plates includes a welding machine 1, an internal toothed belt 2, a number of edge processing mechanisms 210 distributed and connected to the internal toothed belt 2, a driving gear 3, a table plate 5, a linear motor 611, a ceramic side pressing strip 8 and a U-shaped hanging seat 9. Two welding torch heads 110 connected to the welding machine 1 are respectively installed at the end parts of the output ends of two first oil cylinders 120, and a U-shaped hanging seat 9 is installed at the output end of the first oil cylinder 120 located between the two second oil cylinders 130. The linear motor 611 is installed on the inner top wall of the U-shaped hanging plate 610, and both ends of the U-shaped hanging plate 610 are respectively installed at both ends of the top of the table support 6. There is a spacing between the top surface of the U-shaped hanging plate 610 and the bottom of the welding machine 1. The cylinder end parts of the first oil cylinder 120 and the second oil cylinder 130 are both fixedly connected to the bottom of a pulling connecting piece 612 located on the linear motor 611, and both sides of the pulling connecting piece 612 are fixedly connected to the bottom of the welding machine 1 through a connecting structure;

[0033] Combined Figure 7 As shown in the figure, when welding the gap between two plates 10 to be welded, the linear motor 611 is operated to drive the welding machine 1, the first oil cylinder 120 and the second oil cylinder 130 connected through the pulling connecting piece 612 to move from one end to the other end together. At the same time, one of the first oil cylinders 120 is in the extended state, so that the welding torch head 110 connected to the output end of the first oil cylinder 120 approaches the welding part to be welded and performs welding, and the welding process of the elevator plates can be completed.

[0034] As Figure 1 、 Figure 3 、 Figure 4 and Figure 7 As shown in the figure, the edge processing mechanism 210 includes a cleaning disc 211, a slider 212, a U-shaped support 213, a side guide hole 214 and a spring 215. The middle part of the cleaning disc 211 is rotatably installed between two sliders 212, and the two sliders 212 are respectively slidably connected to the side guide holes 214 located on both sides of the U-shaped support 213. The bottom of the slider 212 is connected to the inner bottom end of the side guide hole 214 through a spring 215. The bottom of the U-shaped support 213 is fixedly connected to the corresponding part of the internal toothed belt 2. A part of the cleaning disc 211 extends beyond the welding station strip hole 510, and the welding station strip hole 510 is opened in the middle of the table plate 5. The partial surfaces on both sides of the cleaning disc 211 are respectively in contact with the side surfaces of the edges of the two plates 10 to be welded, and the weld spacing dimension between the edges of the two plates 10 to be welded is greater than the width dimension of the ceramic side pressing strip 8. The structures on both sides of the cleaning disc 211 are not limited to the distribution of bristles;

[0035] When two plates to be welded are placed flat on the platen 5 and need to be edge-aligned, the part of the cleaning disc 211 that extends beyond the strip hole 510 of the welding station is used as an alignment and stopping structure. Combining multiple cleaning discs 211 on the same straight line ensures the neatness of the formation of the weld seam by the two plates 10 to be welded.

[0036] Combined with Figure 3 and Figure 7 As shown, the tooth surface inside the inner tooth belt 2 is in meshing transmission connection with four driving gears 3 distributed in a matrix. The four driving gears 3 are respectively rotatably installed at the four corners of the gear carrier 4. A servo motor is installed at one of the corners of the gear carrier 4, and the servo motor is connected to the shaft end on one side of a driving gear 3. The two ends of the gear carrier 4 are respectively installed on the inner side walls of both sides of the table bracket 6;

[0037] After the above edge-alignment is completed and the plates 10 to be welded are fixed in place, the servo motor is operated to drive a corresponding driving gear 3 to rotate, so that the inner tooth belt 2 in meshing transmission connection and the connected edge processing mechanism 210 are in a high-speed running state, achieving the effect of moving each cleaning disc 211 in the edge-alignment gap formed by the two plates 10 to be welded. Finally, the side surface of the cleaning disc 211 is used to clean the corresponding side walls of the plates 10 to be welded, ensuring the cleanliness of the welded part, which helps to improve the welding quality and enhance the welding strength.

[0038] Combined with Figure 5 and Figure 6 As shown, a short shaft is installed on the convex part in the middle of the ceramic side pressing strip block 8, and one end of the short shaft is connected to the reduction motor 910 on one side of the U-shaped hanging seat 9. The bottom of the ceramic side pressing strip block 8 is in contact with the corresponding edge processing mechanism 210 through movement;

[0039] Before the welding torch head 110 performs moving welding, the reduction motor 910 operates to drive one end of the ceramic side pressing strip block 8 connected by the short shaft to turn downward, which has the effect of pressing the cleaning disc 211 under the inner side of one end of the ceramic side pressing strip block 8 into the U-shaped support 213 under the action of the spring 215. At the same time, combined with the ceramic side pressing strip block 8 that moves simultaneously with the welding torch head 110, it is beneficial to orderly move the cleaning disc 211 away from between the two plates 10 to be welded, providing an unobstructed welding environment for the moving welding of the welding torch head 110;

[0040] When welding is completed at a certain point, the annular surface of the cleaning disc 211 reset by the spring 215 contacts the lower part of the previously welded relatively low-temperature point at that point;

[0041] When the elevator plate is welded, turn the elevator plate over, and at the same time place the welded part of the straight weld at the strip hole 510 of the welding station, and the welded part of the straight weld contacts the annular surface of the cleaning disc 211. When the elevator plate is fixed, run the servo motor to drive a corresponding driving gear 3 to rotate, so that the inner tooth belt 2 connected by meshing transmission and the opposite side processing mechanism 210 connected thereto are in a high-speed running state, so that the cleaning disc 211 in the opposite side processing mechanism 210 moves quickly, playing a role in surface treatment of the weld welding part.

[0042] Combined with Figure 2 and Figure 5 As shown, side strip plates 11 are installed on both sides of the bottom orifice of the strip hole 510 of the welding station, and supporting gears 12 are rotatably installed between the two side strip plates 11, and each supporting gear 12 is meshed and driven with the corresponding tooth surface on the inner side of the inner tooth belt 2;

[0043] Through the distributed supporting gears 12, the corresponding parts of the inner tooth belt 2 are supported, and at the same time, the inner tooth belt 2 at this part can be prevented from sagging, ensuring the stability of the position movement of the cleaning disc 211.

[0044] As Figure 1 and Figure 7 As shown, a carrier block 710 is slidably installed in the side groove 520, and an electromagnet 720 is inlaid on the surface of the carrier block 710. One side of the carrier block 710 is connected to the output end of a push-pull cylinder 7 connected to the outer end of the side groove 520. The electromagnet 720 and the push-pull cylinder 7 can be used to complete the position movement and fixation of the plate 10 to be welded.

[0045] Furthermore, a strip-shaped protective cover 410 is installed at the bottom of the gear carrier 4, and the inner tooth belt 2 and the opposite side processing mechanism 210 connected to the inner tooth belt 2 are surrounded inside the strip-shaped protective cover 410.

[0046] Furthermore, the table plate 5 is installed on the top of the table support 6, and side grooves 520 are distributed on the front and rear parts of the surface of the table plate 5.

[0047] Working principle: Combined with Figure 7 As shown, when welding the gap between two plates 10 to be welded, run the linear motor 611 to drive the electric welding machine 1, the first oil cylinder 120 and the second oil cylinder 130 connected by the pulling connecting piece 612 to move from one end to the other end together. At the same time, one of the first oil cylinders 120 is in an extended state, so that the welding torch head 110 connected to the output end of the first oil cylinder 120 approaches the part to be welded and performs welding, and the welding process of the elevator plate can be completed;

[0048] When two plates to be welded are placed flat on the platen 5 and edge alignment is required, the part of the cleaning disc 211 that extends beyond the strip hole 510 of the welding station is used as an alignment and stopping structure. Combining multiple cleaning discs 211 on the same straight line ensures the neatness of the formation of the weld seam for the two plates 10 to be welded;

[0049] Combined with Figure 3 and Figure 7 As shown, after the above-mentioned edge alignment is completed and the plates 10 to be welded are fixed in place, the servo motor is operated to drive a corresponding drive gear 3 to rotate, causing the inner tooth belt 2 connected by meshing transmission and the edge processing mechanism 210 to be in a high-speed operating state, achieving the effect of moving each cleaning disc 211 in the edge processing mechanism 210 within the gap formed by the edge alignment of the two plates 10 to be welded. Finally, the side surface of the cleaning disc 211 is used to clean the impurities on the corresponding side walls of the plates 10 to be welded, ensuring the cleanliness of the welded part, contributing to improving the welding quality and enhancing the welding strength;

[0050] Before the welding torch head 110 performs mobile welding, the reduction motor 910 is operated to drive one end of the ceramic side pressing strip block 8 connected by a short shaft to rotate downward, serving to press the cleaning disc 211 below the inner side of one end of the ceramic side pressing strip block 8 into the U-shaped support 213 under the action of the spring 215. At the same time, combined with the ceramic side pressing strip block 8 that moves simultaneously with the welding torch head 110, it is beneficial to orderly move the cleaning disc 211 away from between the two plates 10 to be welded, providing an unobstructed welding environment for the mobile welding of the welding torch head 110;

[0051] When welding is completed at a certain point, the lower part of the previously welded relatively low-temperature point at that point contacts the annular surface of the cleaning disc 211 reset by the spring 215;

[0052] When the elevator plate is welded, turn the elevator plate over, and at the same time place the welded part of the straight weld seam at the strip hole 510 of the welding station, and the welded part of the straight weld seam contacts the annular surface of the cleaning disc 211. When the elevator plate is fixed in place, operate the servo motor to drive a corresponding drive gear 3 to rotate, causing the inner tooth belt 2 connected by meshing transmission and the edge processing mechanism 210 to be in a high-speed operating state, enabling the cleaning disc 211 in the edge processing mechanism 210 to move quickly, serving to surface-treat the welded part of the weld seam;

[0053] Through the distributed support gears 12, the corresponding part of the inner tooth belt 2 is supported, and at the same time, the sagging of the inner tooth belt 2 at this part can be prevented, ensuring the stability of the position movement of the cleaning disc 211.
