Description

Technical Field

[0001] This invention belongs to the field of welding tools, and in particular relates to a welding workbench for welding processes in machining. Background Technology

[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding uses various energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Besides its use in factories, welding can be performed in a variety of environments, such as outdoors, underwater, and in space. Regardless of the location, welding can pose dangers to operators, so appropriate protective measures must be taken. Potential injuries from welding include burns, electric shock, vision impairment, inhalation of toxic fumes, and excessive ultraviolet radiation exposure.

[0003] During welding, the workpiece and the solder melt to form a molten zone. After the molten pool cools and solidifies, a bond is formed between the materials. Pressure is usually required during this process. There are many energy sources for welding, including gas flame, electric arc, laser, electron beam, friction, and ultrasound.

[0004] Most existing welding workbenches are height-fixed, which requires manual handling when welding larger workpieces. Once the workpiece is placed on the workbench, it is difficult to move it, affecting welding efficiency. Summary of the Invention

[0005] This invention provides a welding workbench for machining welding processes, aiming to solve the problem that existing welding workbench requires manual handling of workpieces during welding.

[0006] This invention is implemented as follows: a welding workbench for machining welding processes, comprising:

[0007] The base is horizontally positioned and connected to a parallel work platform via multiple symmetrically arranged telescopic components. The work platform has multiple protrusions, and each protrusion has a ball groove with balls installed inside, allowing the workpiece to move freely on the work platform.

[0008] The uprights are symmetrically installed on both sides of the work platform, and a crossbar is fixedly installed on the upper part of the uprights. A flip-up flap is rotatably installed on the crossbar, and the flip-up flap is connected to the work platform through a cylinder.

[0009] A support frame is provided on the working platform, and the support frame can be fitted into the groove formed between two adjacent protrusions;

[0010] The lifting mechanism is mounted on the base. When the lifting mechanism is working, it first abuts against the support frame until the height of the support frame exceeds the height of the ball bearings, and then abuts against the working platform to drive the working platform to rise.

[0011] A welding mechanism is provided on the flip plate and is used to perform welding on the workpiece placed on the support frame.

[0012] Furthermore, the lifting mechanism includes a bidirectional drive assembly mounted on the base, a lifting plate connected to the bidirectional drive assembly and disposed between the base and the work platform, and pads adapted to the lifting plate and disposed at both ends of the support frame;

[0013] The pad is fixedly connected to the support frame via a connecting rod.

[0014] Furthermore, the bidirectional drive assembly includes a first drive device fixedly mounted on the base, a bidirectional lead screw connected to the output shaft of the first drive device and rotatably mounted on the base, and two threaded sleeves symmetrically arranged on and cooperating with the bidirectional lead screw. The threaded sleeves are connected to the lifting plate through a support rod.

[0015] The lower two sides of the threaded sleeve are rotatably mounted with multiple pulleys that are rolledly connected to the base.

[0016] Furthermore, the welding mechanism includes a power assembly disposed on the flip plate, a reciprocating assembly connected to the power assembly via a connecting structure and disposed on the flip plate, two rubber grooved wheels rotatably mounted on the reciprocating assembly, and a guide sleeve fixedly disposed on the reciprocating assembly.

[0017] Furthermore, the power assembly includes a second drive device fixedly mounted on the flip plate, two pulleys rotatably mounted on the flip plate, and a belt sleeved on the pulleys, the belt being connected to the connecting structure.

[0018] Furthermore, the connection structure includes a pulley rotatably mounted on the belt and a connector fixedly mounted on the reciprocating assembly;

[0019] The connector is provided with a through groove, the pulley is tumbled to the through groove, and the connector is fixedly connected to the guide sleeve.

[0020] Furthermore, the reciprocating assembly includes two guide rods fixedly mounted on the flap, a movable block slidably disposed on the guide rods, and a meshing structure disposed between the movable block and the flap, the meshing structure connecting one of the rubber grooved wheels;

[0021] The movable block is fixedly connected to the connector.

[0022] Furthermore, the meshing structure includes a rack plate fixedly mounted on the flip plate and a gear rotatably mounted on the moving block and meshing with the rack plate;

[0023] The gear is fixedly connected to the shaft of one of the rubber grooved wheels.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] Since most existing welding workbenches have a fixed height, the workpiece needs to be manually moved onto the workbench during the welding process. This is especially true for larger workpieces, which are difficult to move once placed on the workbench. Therefore, by setting up a lifting mechanism, the work platform can be lowered to a certain height, reducing the physical exertion during manual handling. At the same time, with the help of the ball bearings, the workpiece can be easily moved after being placed on the work platform. After the workpiece is positioned, the lifting component can drive the support frame to rise, raising the workpiece to a certain height, and then drive the work platform to rise, separating the workpiece from the ball bearings, ensuring stability during the welding process and improving welding quality.

[0026] Furthermore, the welding mechanism enables welding to be performed automatically, requiring only the assistance of workers, thus reducing the amount of manual labor. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] To effectively illustrate the embodiments of the present invention, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0038] Please see Figure 1-5 The present invention provides a welding workbench for welding processes in machining, so as to solve the problem that existing welding workbench requires manual handling of workpieces during welding.

[0039] This invention provides a welding workbench for machining welding processes, comprising:

[0040] The base 1 is horizontally arranged and connected to the parallel work platform 3 through a plurality of symmetrically arranged telescopic components 2. The work platform 3 is provided with a plurality of protrusions 6, and a ball groove 7 is provided in each protrusion 6. Balls 8 are installed in the ball groove 7 so that the workpiece can move freely on the work platform 3.

[0041] By setting the ball bearings 8, the friction between the workpiece and the work platform 3 is reduced. This is especially beneficial for heavy workpieces, greatly saving the physical effort required to adjust the workpiece position.

[0042] The telescopic kit consists of a fixed sleeve and a telescopic shaft. The fixed sleeve is installed on the base 1, and the telescopic shaft is slidably mounted on the fixed sleeve, with its end away from the fixed sleeve connected to the working platform 3. The main function of both is to ensure the stability between the working platform 3 and the base 1 when the working platform 3 is raised.

[0043] The upright plate 4 is symmetrically installed on both sides of the working platform 3, and a crossbar 5 is fixedly installed on the upper part of the upright plate 4. A flip-up flap 16 is rotatably installed on the crossbar 5, and the flap 16 is connected to the working platform 3 through a cylinder 17.

[0044] The position of the flip plate 16 is adjustable by the cylinder 17. When other welding processes need to be performed on the work platform 1, the flip plate 16 can be flipped by the cylinder 17 to free up space on the work platform 1 and increase the working area.

[0045] Of course, the cylinder 17 mentioned above can also be replaced by a hydraulic cylinder or an electric telescopic rod. This application does not make specific limitations on this, and the optimal choice can be made according to the actual situation.

[0046] A support frame 9 is provided on the work platform 3, and the support frame 9 can be fitted into the groove formed between two adjacent protrusions 6;

[0047] In the initial state, when the work platform 3 is lowered to its lowest point, the support frame 9 engages with the groove formed between the two adjacent protrusions 6. When the workpiece is placed on the work platform 3, the workpiece can be moved easily. After the position of the workpiece is adjusted, the support frame 9 rises faster than the work platform 3 to support the workpiece and prevent it from moving during the welding process.

[0048] The lifting mechanism is mounted on the base 1. When the lifting mechanism is working, it first abuts against the support frame 9, and after raising the support frame 9 to a height exceeding the height of the ball bearing 8, it abuts against the working platform 3 to drive the working platform 3 to rise.

[0049] The lifting mechanism includes a bidirectional drive assembly mounted on the base 1, a lifting plate 15 connected to the bidirectional drive assembly and disposed between the base 1 and the work platform 3, and pads 10 adapted to the lifting plate 15 and disposed at both ends of the support frame 9.

[0050] The pad 10 is fixedly connected to the support frame 9 via a connecting rod;

[0051] The bidirectional drive assembly includes a first drive device 11 fixedly installed on the base 1, a bidirectional lead screw 12 connected to the output shaft of the first drive device 11 and rotatably installed on the base 1, and two threaded sleeves 13 symmetrically arranged on the bidirectional lead screw 12 and cooperating with it. The threaded sleeves 13 are connected to the lifting plate 15 through a support rod 14.

[0052] The lower two sides of the threaded sleeve 13 are rotatably mounted with multiple pulleys that are rolledly connected to the base 1.

[0053] In use, the first drive device 11 is controlled to rotate the double-acting screw 12, causing the threaded sleeves 13 that cooperate with the double-acting screw 12 to move closer or further apart. This, in turn, drives the lifting plate 15 to rise or fall via the support rod 14. When the lifting plate 15 rises, it first abuts against the pad block 10, causing the support frame 9 and the workpiece to rise. It should be noted that the working platform 3 will not rise at this time. When the lifting plate 15 drives the support frame 9 to rise until the workpiece just disengages from the ball bearing 8, the lifting plate 15 abuts against the lower part of the working platform 3, causing the support frame 9 and the working platform 3 to rise. During the rising process, the rising speed of the support frame 9 and the working platform 3 is the same, meaning that the workpiece will no longer contact the ball bearing 8 during the rising process, ensuring the stability of the workpiece during welding and improving the welding quality.

[0054] It should be noted that the aforementioned drive device is a servo motor whose output shaft can rotate in both directions.

[0055] Furthermore, the aforementioned bidirectional lead screw 12 is provided with an external thread, which engages with the internal thread provided in the threaded sleeve 13. This allows the threaded sleeve 13 to move in the axial direction of the bidirectional lead screw 12 during rotation. Considering that during the process of the lifting plate 15 driving the support frame 9 and the working platform 3 to rise, the weight of the lifting rod 15, the support frame 9, the workpiece, and other parts are all transmitted to the threaded sleeve 13 by the support rod 14. The force may be too great, which could cause the bidirectional lead screw 12 to bend and deform, or cause the load on the first drive device 11 to increase or even damage the first drive device 11 due to excessive friction between the threaded sleeve 13 and the base 1. Therefore, a pulley is provided. On the one hand, it provides support to prevent the bidirectional lead screw 12 from bending and deforming under pressure. On the other hand, it reduces the friction between the threaded sleeve 13 and the base 1, thereby reducing the load on the first drive device 11.

[0056] In detail, there is a one-way transmission effect between the double-acting screw 12 and the threaded sleeve 13. That is, the double-acting screw 12 can drive the threaded sleeve 13 to move, but the threaded sleeve 13 cannot drive the double-acting screw 12 to reverse. This means that when the support frame 9 and the working platform 3 rise to a certain height, even if the first drive device 11 stops, the support frame 9 and the working platform 3 will not move downward, causing the entire working platform 3 to descend.

[0057] A welding mechanism is provided on the flip plate 16 and is used to weld the workpiece placed on the support frame 9.

[0058] The welding mechanism includes a power assembly mounted on the flip plate 16, a reciprocating assembly connected to the power assembly via a connecting structure and mounted on the flip plate 16, two rubber grooved wheels 26 rotatably mounted on the reciprocating assembly, and a guide sleeve fixedly mounted on the reciprocating assembly.

[0059] The power assembly includes a second drive device 18 fixedly installed on the flip plate 16, two pulleys rotatably installed on the flip plate 16, and a belt 19 sleeved on the pulleys, the belt 19 being connected to the connecting structure;

[0060] The connection structure includes a pulley 20 rotatably mounted on the belt 19 and a connector 21 fixedly mounted on the reciprocating assembly;

[0061] The connector 21 is provided with a through groove, the pulley 20 is tumbledly connected to the through groove, and the connector 21 is fixedly connected to the guide sleeve.

[0062] Furthermore, the length of the aforementioned through groove is greater than the distance between the upper and lower surfaces of the belt 19.

[0063] The reciprocating assembly includes two guide rods 23 fixedly installed on the flap 16, a movable block 22 slidably disposed on the guide rods 23, and a meshing structure disposed between the movable block 22 and the flap 16, wherein the meshing structure is connected to one of the rubber grooved wheels 26;

[0064] The movable block 22 is fixedly connected to the connector 21;

[0065] The meshing structure includes a rack plate 24 fixedly installed on the flip plate 16 and a gear 25 rotatably installed on the moving block 22 and meshing with the rack plate 24;

[0066] The gear 25 is fixedly connected to the shaft of one of the rubber grooved wheels 26.

[0067] In use, by controlling the rotation of the second drive device 18, the belt 19 is driven to rotate, causing the pulley 20 set on the belt 19 to be displaced. The moving block 22 is driven to move on the guide rod 23 through the connecting piece 21, causing the gear 25 installed on the guide rod 23 to rotate under the action of the rack plate 24, and driving the rubber groove wheel 26 to rotate, thus conveying the welding rod placed between the two rubber groove wheels 26 downward.

[0068] It should be emphasized that during the process of the moving block 22 moving from one end to the other, the two rubber grooved wheels 22 just finish feeding a whole welding rod. That is, during the process of the moving block 22 moving from one end to the other, the welding rod is just fully used. At this time, the moving block 22 is adjusted to the initial position (the end away from the second drive device 18), and welding continues after loading the welding rod.

[0069] Taking the embodiment combining all the features described in this application as an example, in use, the workpiece is placed on the work platform 3, and the position of the workpiece is adjusted by the ball bearing 8 so that the position on the workpiece to be welded is exactly below the welding rod. The first drive device 11 is controlled to work, driving the bidirectional lead screw 12 to rotate, so that the two threaded sleeves 13 move closer to each other, and the lifting plate 15 is driven to rise through the support rod 14. During the process of the lifting plate 15 rising, the lifting plate 15 first abuts against the pad 10, driving the support frame 9 to rise until the workpiece separates from the ball bearing 8. Then the lifting plate 15 abuts against the lower part of the work platform, driving the support frame 9 and the work platform 3 to rise together.

[0070] During the welding process, the second drive device 18 is controlled to rotate, thereby driving the belt 19 to move. The belt 19 drives the moving block 22 to move on the guide rod 23 through the pulley 20 and the connecting piece 21. This causes the gear 25 installed on the moving block 22 to rotate under the action of the rack plate 24, and drives one of the rubber grooved wheels 26 to rotate, thus conveying the welding rod downward.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
