Description

Technical Field

[0001] This utility model belongs to the field of hardware processing technology, and specifically relates to a hardware welding device. Background Technology

[0002] Hardware, traditional hardware products, also known as "small hardware," refers to the five metals: gold, silver, copper, iron, and tin. Through manual processing, they can be made into works of art such as knives and swords, or metal devices. In modern society, hardware is more extensive, including hardware tools, hardware parts, daily-use hardware, building hardware, and security products. Welding equipment is required in the processing of hardware parts.

[0003] Currently, the hardware welding equipment has low adaptability to different types of hardware workpieces. For example, when dealing with different types of workpieces such as thin-walled parts adapted to pneumatic clamps, flat parts adapted to flat chucks, and irregular hardware parts (such as arc-shaped brackets) adapted to irregular chucks, the entire set of fixtures needs to be disassembled, reinstalled, and calibrated. This process not only requires removing the fixing bolts of the old fixtures and adjusting the base position, but also repeatedly adjusting the clamping force and positioning accuracy. Therefore, it cannot flexibly match the welding operations of various types of hardware parts in the workshop. Utility Model Content

[0004] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a hardware welding device that solves the problem of low adaptability to hardware workpieces in existing technologies. For example, when dealing with different types of workpieces such as thin-walled parts adapted to pneumatic clamps, flat parts adapted to planar chucks, and irregular hardware parts (such as arc-shaped brackets) adapted to irregular chucks, the entire set of fixtures needs to be disassembled, reinstalled, and calibrated. This process not only requires removing the fixing bolts of the old fixtures and adjusting the base position, but also repeatedly adjusting the clamping force and positioning accuracy, thus making it impossible to flexibly match the welding operations of various types of hardware parts in the workshop.

[0005] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a hardware welding device, including a processing table. An auxiliary welding mechanism is mounted on the center and upper sides of the processing table. The auxiliary welding mechanism includes a pair of assembly bases, and an adapter / replacement mechanism is installed on the center and inner side of the pair of assembly bases. A mounting platform is fixedly provided on the upper center of the processing table, and a reserved slot is provided in the center of the mounting platform. A tilting guide plate is fixed in the center of multiple reserved slots. The adapter / replacement mechanism includes a flat mounting groove and a worm gear. The flat mounting groove is located in the center of the pair of assembly bases. An installation component is installed on one side of the flat mounting groove within the assembly base. An installation clamp seat is inserted into the center of the flat mounting groove. A locking component is installed on one side of the pair of assembly bases.

[0006] Furthermore, the mounting assembly includes a worm gear, which is mounted on one side inside the assembly base. A worm wheel meshes with the upper part of the middle section of the worm gear, and a rotating rod is fixedly mounted in the middle of the worm wheel. A gear is fixedly mounted around a section of the rotating rod, and a rack guide is meshed with the upper and lower sides of the gear. A connecting plate is fixedly mounted on the inner side of the opposite ends of the two rack guides, and a limiting guide rod is provided on the inner side of a pair of connecting plates. Guide grooves are provided on both sides of the interior of the assembly base, and slots are provided on both sides of the mounting fixture seat.

[0007] Furthermore, the limiting guide rods are equidistantly distributed along the inner side of the connecting plate, and the limiting guide rods are horizontally guided to the guide grooves.

[0008] Furthermore, the locking assembly includes a toothed torsion sleeve, which is fixed to one end of the worm gear. A fixed plate is fixed to one side of the assembly base, and a movable groove is provided in the middle of the fixed plate. A movable rod is movably mounted in the middle of the movable groove, and a connecting ring plate is connected to one end of the movable rod. A return spring is connected to the inner periphery of the connecting ring plate, and an insert block is fixed to the other end of the movable rod.

[0009] Furthermore, the insertion surface of the insert is matched with the size of the toothed grooves around the toothed torsion sleeve.

[0010] Furthermore, the auxiliary welding mechanism includes preset slots, which are respectively located on both sides above the processing table. A positive and negative lead screw is installed in the middle of one pair of preset slots, and a servo motor is installed at one end of the positive and negative lead screw. Lead screw sleeves are screwed on both sides of the middle of the positive and negative lead screws, and an assembly table is fixed above the two lead screw sleeves. A sliding rod is fixed in the middle of the other pair of preset slots.

[0011] Furthermore, the slide rod is connected to its mounting base by a movable guide.

[0012] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: When welding different types of hardware parts, this utility model allows personnel to select a mounting fixture with a compatible chuck and install it in the flat mounting slots at opposite ends of two assembly platforms. Then, the operator can pull the connecting ring plate with one hand, stretching the return spring and simultaneously moving the movable rod along the guide groove. Since a block is fixed at the top of the movable rod, this block can disengage from the corresponding tooth groove around the toothed torsion sleeve. In this state, the operator can manually rotate the toothed torsion sleeve to rotate the worm. Because the middle section of the worm meshes with the worm wheel, the meshing worm wheel can drive the rotating rod and the gears around it to rotate. Furthermore, because the gears are misaligned and meshed with a rack guide frame on their upper and lower sides, a pair of misaligned... The rack and pinion guide frame can carry the limiting guide rods set on the inner side of each end, and move along the preset guide grooves on both sides of the inner side for alignment and displacement. Since there are slots on both sides of the mounting fixture, the ends of the limiting guide rods can be inserted into the slots to achieve stable assembly of the mounting fixture. After assembly, the operator slowly loosens the connecting ring plate, so that the return spring returns to its original position and drives the insert block to be inserted into the corresponding tooth groove around the tooth groove torsion sleeve, thus forming a locking limit. It is worth mentioning that the mounting fixture can be adjusted to a horizontal position in the flat mounting groove according to the height and other parameters of the workpiece to be clamped, so as to ensure that the bottom surface of different workpieces can be stably mounted on the mounting platform, thereby improving the load capacity of the device.

[0013] In this invention, after the mounting fixture seat in the flat mounting slot of a pair of mounting bases stably clamps the workpiece to be welded, the operator can start the servo motor to make the positive and negative lead screws rotate accordingly. Since the pair of lead screw sleeves cooperate with the positive and negative lead screws, they will carry their respective fixed mounting bases and the workpieces clamped on the mounting bases, and move in relative directions in coordination with the slide rods until the two workpieces come into contact with each other. At this time, welding operations can be carried out on the contact parts of the workpieces. During this process, the welding slag and other waste generated by welding will be guided and discharged in an inclined direction along the inclined guide plates set in the reserved slots opened on the mounting platform.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This specific embodiment is a hardware welding device, the structural schematic diagram of which is shown below. Figures 1 to 4As shown, the system includes a processing table 1. An auxiliary welding mechanism 2 is mounted on the center and upper sides of the processing table 1. The auxiliary welding mechanism 2 includes a pair of mounting bases 25, and an adapter / replacement mechanism 3 is mounted on the center and inner side of the pair of mounting bases 25. A mounting platform 4 is fixedly mounted on the upper center of the processing table 1, and a reserved slot 5 is provided in the center of the mounting platform 4. A tilting guide plate 6 is fixedly mounted in the center of multiple reserved slots 5. The auxiliary welding mechanism 2 includes preset slots 21, which are located on the upper sides of the processing table 1. A positive and negative lead screw 22 is installed in the center of one pair of preset slots 21, and a servo motor 23 is installed at one end of the positive and negative lead screw 22. Lead screw sleeves 24 are screwed onto both sides of the center of the positive and negative lead screw 22, and a mounting base 25 is fixedly mounted above the two lead screw sleeves 24. The other pair of preset slots... A sliding rod 26 is fixedly installed in the middle of the groove 21. The sliding rod 26 is connected to the assembly base 25 by a movable guide. After the installation fixture seat 33 installed in the flat mounting groove 31 of a pair of assembly bases 25 stably clamps the workpiece to be welded through the chuck, the operator can start the servo motor 23 to make the positive and negative lead screws 22 rotate accordingly. Since a pair of lead screw sleeves 24 cooperate with the positive and negative lead screws 22, they will carry their respective fixed assembly bases 25 and the workpieces clamped on the assembly bases 25, and move in relative directions with the sliding rod 26 until the two workpieces come into contact with each other. At this time, welding operations can be carried out on the contact part of the workpieces. During this process, the welding slag and other waste generated by welding will be guided and discharged in the inclined direction along the inclined guide plate 6 set in the reserved slots 5 opened on the mounting platform 4.

[0019] The adapter replacement mechanism 3 includes a flat mounting slot 31 and a worm gear 321. The flat mounting slot 31 is located in the middle of a pair of assembly platforms 25. An installation assembly 32 is installed on one side of the flat mounting slot 31 inside the assembly platform 25. The installation assembly 32 includes a worm gear 321, which is installed on one side inside the assembly platform 25. A worm wheel 322 meshes with the upper part of the middle section of the worm gear 321. A rotating rod 323 is fixed in the middle of the worm wheel 322. A gear 324 is fixed around a section of the rotating rod 323. A rack guide frame 325 meshes with the upper and lower sides of the gear 324. A connecting plate 326 is fixed inside the opposite ends of the two rack guide frames 325. A limiting guide rod 327 is provided on the inner side of the pair of connecting plates 326. The two inside the assembly platform 25... A guide groove 328 is provided on the side, and slots 329 are provided on both sides of the mounting fixture seat 33. Limiting guide rods 327 are equidistantly distributed along the inner side of the connecting plate 326, and the limiting guide rods 327 and the guide grooves 328 are horizontally guided. The mounting fixture seat 33 is inserted into the middle of the flat mounting groove 31. A locking assembly 34 is installed on one side of a pair of mounting platforms 25. The locking assembly 34 includes a toothed torsion sleeve 341, and the toothed torsion sleeve 341 is fixed to one end of the worm gear 321. A fixing plate 342 is fixed on one side of the mounting platform 25, and a movable groove 344 is opened in the middle of the fixing plate 342. A movable rod 343 is movable in the middle of the movable groove 344, and one end of the movable rod 343 is connected to a connecting ring plate 345. The inner periphery of the connecting ring plate 345 is connected to a composite... The other end of the spring 346 and the movable rod 343 is fixedly provided with a plug 347. The insertion surface of the plug 347 matches the size of the toothed groove around the toothed torsion sleeve 341. When welding different types of hardware parts, the operator can select a mounting fixture seat 33 with a matching chuck and install it in the flat mounting groove 31 provided at the opposite ends of the two assembly seats 25. Then, the operator can pull the connecting ring plate 345 with one hand, so that the return spring 346 is stretched and the movable rod 343 is moved along the movable groove 344. Since the top end of the movable rod 343 is fixedly provided with a plug 347, the plug 347 can disengage from the corresponding toothed groove around the toothed torsion sleeve 341. At this state, the operator can manually rotate the toothed torsion sleeve 341 to rotate the worm gear 321. The middle section of 321 meshes with the worm gear 322. Under the meshing transmission, the worm gear 322 can drive the rotating rod 323 and the gear 324 around it to rotate. Since the gear 324 is staggered and meshed with the upper and lower sides, the rack guide bracket 325 is provided. At this time, the pair of staggered rack guide brackets 325 can respectively carry the limiting guide rods 327 on their inner ends to perform alignment displacement along the pre-set guide grooves 328 on both sides of the inside. Since the mounting fixture base 33 has slots 329 on both sides, the ends of the limiting guide rods 327 can be aligned and inserted into the slots 329 to achieve stable assembly of the mounting fixture base 33. After the assembly is completed, the personnel slowly loosen the connecting ring plate 345, so that the return spring 346 returns to its original position and drives the insert block 347 to be aligned and inserted into the corresponding tooth groove around the tooth groove torsion sleeve 341.A locking limit is achieved. It's worth noting that the mounting fixture 33 can adjust its horizontal position within the flat mounting slot 31 according to parameters such as the height of the workpiece to be clamped. This ensures that the bottom surface of different workpieces can be stably mounted on the mounting platform 4, thereby improving the load-bearing capacity of the device.

[0020] Working principle: When welding different types of hardware parts, the operator can select a mounting fixture 33 with a compatible chuck and install it in the flat mounting slots 31 at opposite ends of the two assembly bases 25. Then, the operator can pull the connecting ring plate 345 with one hand, causing the return spring 346 to stretch and simultaneously guide the movable rod 343 to move along the movable slot 344. Since the top of the movable rod 343 is fixed with a plug 347, the plug 347 can disengage from the corresponding toothed groove around the toothed torsion sleeve 341. At this state, the operator can manually rotate the toothed torsion sleeve 341 to move the worm gear 321. Rotation occurs because the middle section of the worm 321 meshes with the worm wheel 322. The meshing transmission of the worm wheel 322 causes the rotating rod 323 and its surrounding gear 324 to rotate. Since the gear 324 has a misaligned meshing rack guide frame 325 on its upper and lower sides, the pair of misaligned rack guide frames 325 can each carry a limiting guide rod 327 on its inner side, moving along the pre-set guide grooves 328 on both sides of the inner side for alignment and displacement. Because the mounting fixture base 33 has slots 329 on both sides, the ends of the limiting guide rods 327 can be inserted into these slots 329, thus aligning the mounting fixture. After the fixture base 33 is stably assembled, the operator slowly loosens the connecting ring plate 345, causing the return spring 346 to reset and drive the insert block 347 to align and insert into the corresponding toothed groove around the toothed torsion sleeve 341, thus forming a locking limit. It is worth mentioning that the fixture base 33 can be appropriately adjusted to its horizontal position within the flat mounting groove 31 according to parameters such as the height of the workpiece to be clamped, thereby ensuring that the bottom surface of different workpieces can be stably mounted on the mounting platform 4, thereby improving the load-bearing capacity of the device. Secondly, when the fixture base 33 assembled in the flat mounting groove 31 of a pair of mounting platforms 25 is in operation... After the workpiece to be welded is securely clamped in the chuck, the operator can start the servo motor 23, causing the positive and negative lead screws 22 to rotate. Since a pair of lead screw sleeves 24 cooperate with the positive and negative lead screws 22, they will carry their respective fixed assembly bases 25 and the workpieces clamped on the assembly bases 25, and move in relative directions in coordination with the slide rod 26 until the two workpieces come into contact with each other. At this time, welding operations can be carried out on the contact parts of the workpieces. During this process, the welding slag and other waste generated will be guided and discharged along the inclined guide plate 6 set in the reserved slots 5 opened on the mounting platform 4.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
