Description

Technical Field

[0001] This invention relates to the field of hardware product processing equipment technology, and in particular to an anti-offset welding device for hardware product processing. Background Technology

[0002] Traditional hardware products, also known as "small hardware," refer 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 other metal components. Modern hardware is much broader, including hardware tools, hardware parts, daily-use hardware, building hardware, and security products. When processing some hardware products, such as ring-shaped hardware workpieces, it is necessary to weld the two ends of the workpiece together to form a ring. To prevent misalignment at the weld joint during welding, fixtures and other positioning devices are often used to position both ends of the workpiece simultaneously. However, these positioning devices can also hinder the operation of the welding torch. Therefore, some welding equipment is equipped with step-back positioning devices. During welding, the positioning devices are gradually withdrawn, thus preventing the positioning devices from obstructing the operation of the welding torch. However, to ensure effective clamping and positioning of the workpiece, the clamping surface of the positioning component often has elastic rubber, silicone, or metal pads. When in contact with the workpiece, these elastic structures deform and adhere tightly to the workpiece. This results in these elastic structures remaining tightly against the workpiece even as the positioning component is gradually retracted. The friction between the elastic structures and the workpiece makes retraction difficult and causes significant wear on these elastic structures. Summary of the Invention

[0003] The present invention aims to solve the problem that traditional step-back positioning parts are prone to difficulty in exiting during welding due to friction of the elastic structure.

[0004] To solve the above-mentioned technical problems, the present invention provides an anti-deviation welding device for hardware product processing, including a device frame and a positioning component. An inner pressing component and an outer pressing component are provided in the device frame. The inner pressing component and the outer pressing component are both connected to the positioning component. The inner pressing component and the outer pressing component have the same structure. A lifting mechanism for driving the inner pressing component and the outer pressing component to move is provided in the device frame. The internal pressing assembly includes a guide rail connected to the lifting end of the lifting actuator. A hollow seat and a welded assembly are slidably connected to the guide rail. Multiple hollow seats are provided. A lifting rod is vertically slidably disposed within each hollow seat and connected to a positioning component. A push rod is horizontally slidably disposed within each hollow seat. A linkage component is disposed within each hollow seat, connected to the push rod and the linkage component, which in turn is connected to the lifting rod. Movement of the push rod drives movement of the linkage component, thereby moving the lifting rod. An elastic reset component is disposed within each hollow seat, pushing the push rod to reset. The hollow seat extends into... A roller is fixed at one end of the guide rail, and a cross-shaped limiting strip is fixed on the inner wall of the guide rail. The roller is rolled within the gap between the cross-shaped limiting strip and the guide rail. Welding is carried out while the welding assembly moves. During the movement, the dispersed hollow seats are pushed one by one. Before the hollow seat is pushed, its corresponding push rod is pushed to retract the lifting rod, thereby causing the positioning part to move away from the end of the workpiece and expose the clamped and positioned position. This will not hinder the welding of the welding assembly. Moreover, the positioning part moves away from the workpiece before being pushed. The elastic structure inside the positioning part will not have dynamic friction with the workpiece during movement, which greatly reduces the wear of the elastic structure.

[0005] Furthermore, the linkage includes a fixed seat, which is fixedly disposed inside a hollow seat. The fixed seat is rotatably connected to a rotating shaft via a bearing. A gear and a disc are coaxially fixed on the outer wall of the rotating shaft. The gear meshes with a rack, which is fixedly connected to a push rod. A connecting arm is hinged to the outer edge of the disc. The end of the connecting arm away from the disc is hinged to the end of the lifting rod. When the push rod is pushed to move, the push rod drives the rack to move. The movement of the rack drives the gear to rotate. The rotation of the gear drives the rotating shaft to rotate, which in turn drives the disc to rotate. The rotation of the disc pulls the connecting arm to move, which in turn pulls the lifting rod to retract into the hollow seat.

[0006] Furthermore, the elastic reset component includes a connecting plate, which is fixedly connected to the push rod. A spring is fixedly provided on the outer wall of the connecting plate, and the end of the spring away from the connecting plate is fixedly connected to the inner wall of the hollow seat.

[0007] Furthermore, the equipment frame is equipped with a position adjustment component for adjusting the position of the workpiece, and a linkage locking component for locking the hollow seat is provided between the hollow seat and the guide rail.

[0008] Furthermore, the linkage locking assembly includes a socket plate and a connecting arm two. The socket plate is fixed in the guide rail. One end of the connecting arm two is hinged to the outer edge of the disc, and the other end is hinged to a plug rod. The plug rod moves through the inner wall of the hollow seat one. The plug rod and the lifting rod one are symmetrically arranged, one above the other. The plug rod is inserted into the socket on the socket plate.

[0009] Furthermore, the welding assembly includes a sliding plate, one end of which is slidably disposed within a guide rail, and a welding torch is fixedly mounted on the outer wall of the sliding plate, with the sliding plate directly facing the foremost push rod.

[0010] Furthermore, the positioning component includes a hollow seat two. The outer wall of the hollow seat two facing away from the workpiece end is fixedly connected to the lifting rod. A connecting rod is provided inside the hollow seat two. A threaded rod is rotatably connected inside the hollow seat two via a bearing. An internal threaded block is threadedly fitted on the outer wall of the threaded rod. The internal threaded block is a rectangular block and movably penetrates the outer wall of the hollow seat two. Three connecting rods are provided on the hollow seat two. The left and right connecting rods are fixedly connected to the hollow seat two, and the middle connecting rod is fixedly connected to the internal threaded block. A rigid head is fixedly provided at the end of the connecting rod away from the hollow seat two. A silicone pad is fitted on the outer wall of the rigid head.

[0011] Furthermore, the lifting mechanism includes a bidirectional electric slide rail one, a bidirectional electric slide rail two, and a lifting plate. The bidirectional electric slide rail one and the bidirectional electric slide rail two are fixed inside the equipment frame. The lifting plate is provided in two sets, one set of which is connected to the inner pressing component and the other set of which is connected to the outer pressing component. The moving ends of the bidirectional electric slide rail one and the bidirectional electric slide rail two are respectively fixedly connected to the two sets of lifting plates.

[0012] Furthermore, the position adjustment assembly is provided in four sets. The position adjustment assembly includes a telescopic cylinder, which is fixedly connected to the equipment frame. A U-shaped frame is fixedly provided at the telescopic end of the telescopic cylinder. A rotating shaft two is rotatably connected to the inner side of the U-shaped frame through a bearing. A guide wheel is sleeved on the rotating shaft two, and there are two guide wheels on the same rotating shaft two, one in front and one in back. The two guide wheels block the front and back of the workpiece respectively. A fixing nut is threaded on the rotating shaft two, and the fixing nut fixes the guide wheel on the rotating shaft two.

[0013] Furthermore, a push plate is fixed to one end of the push rod that extends outside the hollow seat, and the push plate is directly opposite the sliding plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The welding assembly moves while welding. During the movement, the dispersed hollow seats are pushed one by one. Before the hollow seat is pushed, its corresponding push rod is pushed to retract the lifting rod, thereby making the end of the positioning member away from the workpiece and exposing the clamped and positioned position, which will not hinder the welding of the welding assembly. Moreover, the positioning member is pushed away from the workpiece first, and the elastic structure inside the positioning member will not have dynamic friction with the workpiece when moving, which greatly reduces the wear of the elastic structure.

[0015] When the push rod is pushed and moved, the push rod drives the rack to move, the rack to move and drive the gear to rotate, the gear to rotate the shaft, and then drive the disc to rotate. The rotation of the disc pulls the connecting arm to move, and then pulls the lifting rod to retract inward into the hollow seat, thereby moving the positioning part away from the end of the workpiece, so that the positioning part is no longer tightly pressing the end of the workpiece.

[0016] By inserting one end of the insertion rod into the insertion hole, the insertion rod is axially limited along the guide rail, which in turn limits the hollow seat 1 along the guide rail. When the disc rotates, it synchronously drives the connecting arm 1 and connecting arm 2 to move, which in turn drives the lifting rod and the insertion rod to move. When the lifting rod retracts, the insertion rod also retracts, thus realizing that when the hollow seat 1 needs to be moved, the insertion rod retracts and disengages from the insertion hole, releasing the lock on the hollow seat 1.

[0017] The workpiece is clamped and fixed from four positions by four sets of position adjustment components to ensure the stability of the fixation. The U-shaped frame is moved by the extension and retraction of the telescopic cylinder, which in turn moves the second rotating shaft. The movement of the second rotating shaft moves the guide wheel, so that the guide wheel can contact the edge of the workpiece. The position of the fixing nut is adjusted by tightening the fixing nut, which in turn adjusts the position of the guide wheel, so that the two guide wheels on the same second rotating shaft simultaneously abut against the front and back of the workpiece, which plays a role in limiting the position of the workpiece.

[0020] 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, not all, of the embodiments of the present invention. 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.

[0021] Please see Figure 1-9 This invention provides a technical solution: an anti-offset welding device for hardware product processing, including a frame 1 and positioning components 6. The frame 1 is provided with an inner pressing component 3 and an outer pressing component 4. The inner pressing component 3 and the outer pressing component 4 respectively push the positioning components 6 to clamp the end of the workpiece 2 from the inner and outer sides. The inner pressing component 3 and the outer pressing component 4 have the same structure. The frame 1 is provided with a lifting action component 5 to move the inner pressing component 3 and the outer pressing component 4. The position of the inner pressing component 3 and the outer pressing component 4 is adjusted by the lifting action component 5 so that the inner pressing component 3 and the outer pressing component 4 can be aligned with the end of the workpiece 2, so that the upper and lower positioning components 6 can clamp the end of the workpiece 2 from the upper and lower directions, thereby clamping and positioning the end of the workpiece 2. The inner pressing assembly 3 includes a guide rail 301, which is connected to the lifting end of the lifting actuator 5. A hollow seat 302 and a welding assembly 9 are slidably connected to the guide rail 301. Multiple hollow seats 302 are provided. A lifting rod 303 is vertically slidably disposed within the hollow seat 302 and is connected to a positioning component 6. A push rod 304 is horizontally slidably disposed within the hollow seat 302. A linkage component 305 is disposed within the hollow seat 302. When the push rod 304 is pushed, the linkage component 305 pushes the lifting rod 303 to move. An elastic reset component 306 is disposed within the hollow seat 302, which pushes the push rod. 304 is reset. Guide rail 301 is set for mounting hollow base 302 and welding assembly 9. Multiple hollow bases 302 are used to mount multiple lifting rods 303, and then multiple positioning elements 6 are mounted. Multiple positioning elements 6 clamp and position the workpiece 2 from different positions. Welding assembly 9 is pushed from front to back. During the pushing process, welding assembly 9 will first contact push rod 304, and then push push rod 304 to move. The movement of push rod 304 will drive linkage 305 to move, causing lifting rod 303 to move into hollow base 302, thereby moving positioning elements 6 away from the end of workpiece 2, so that positioning elements 6 no longer tightly press against the end of workpiece 2. After push rod 304 moves into position, it pushes hollow seat 302 to move. The movement of hollow seat 302 causes lifting rod 303 to move, which in turn moves positioning component 6, exposing the area originally held and positioned by positioning component 6. Welding assembly 9 can then weld this area. As welding assembly 9 continues to move, it pushes push rod 304 corresponding to the first hollow seat 302 to continue moving. Push rod 304 then contacts the push rod 304 corresponding to the next hollow seat 302, pushing this push rod 304 to move, causing the positioning component 6 corresponding to that hollow seat 302 to move and separate from the workpiece 2. Then, this... The hollow seat 302 is pushed, further exposing the clamped and positioned part on the workpiece 2. The welding assembly 9 moves and welds at the same time. During the movement, the dispersed hollow seats 302 are pushed one by one. Before the hollow seat 302 is pushed, its corresponding push rod 304 is pushed, causing the lifting rod 303 to retract, thereby causing the positioning part 6 to move away from the end of the workpiece 2 and exposing the clamped and positioned position. This will not hinder the welding of the welding assembly 9. Moreover, the positioning part 6 moves away from the workpiece 2 before being pushed. The elastic structure inside the positioning part 6 will not have dynamic friction with the workpiece 2 when it moves, which greatly reduces the wear of the elastic structure. A cross-shaped limiting strip 10 is fixedly provided on the inner wall of the guide rail 301, and a roller 11 is fixedly provided at one end of the hollow seat 302 that extends into the guide rail 301. The roller 11 is rolled in the gap between the cross-shaped limiting strip 10 and the guide rail 301. Linkage component 305 includes a fixed base 3051, which is fixedly disposed inside a hollow base 302. The fixed base 3051 is rotatably connected to a rotating shaft 3052 via a bearing. A gear 3053 and a disc 3055 are coaxially fixed to the outer wall of the rotating shaft 3052. The gear 3053 meshes with a rack 3054, which is fixedly connected to a push rod 304. A connecting arm 3056 is hinged to the outer edge of the disc 3055. The end of 056 away from the disc 3055 is hinged to the end of the lifting rod 303. When the push rod 304 is pushed to move, the push rod 304 drives the rack 3054 to move. The movement of the rack 3054 drives the gear 3053 to rotate. The rotation of the gear 3053 drives the rotating shaft 3052 to rotate, which in turn drives the disc 3055 to rotate. The rotation of the disc 3055 pulls the connecting arm 3056 to move, which in turn pulls the lifting rod 303 to retract into the hollow seat 302. The elastic reset component 306 includes a connecting plate 3061, which is fixedly connected to the push rod 304. A spring 3062 is fixedly mounted on the outer wall of the connecting plate 3061. The end of the spring 3062 away from the connecting plate 3061 is fixedly connected to the inner wall of the hollow seat 302. When the push rod 304 is pushed and moved, the push rod 304 drives the connecting plate 3061 to move. The moving connecting plate 3061 compresses the spring 3062, and the spring 3062 accumulates elastic potential energy. When the push rod 304 is no longer pushed... When pushed, the spring 3062 releases its elastic potential energy to reset. During this process, it pushes the connecting plate 3061 to reset, which in turn pushes the push rod 304 to reset. The reset of the push rod 304 will drive the rack 3054 to move in the opposite direction, which in turn drives the gear 3053 to rotate in the opposite direction. Then, the rotating shaft 3052 rotates in the opposite direction, which in turn causes the disc 3055 to rotate in the opposite direction. Then, the lifting rod 303 extends outward from the hollow seat 302, which in turn extends the positioning piece 6 outward, preparing for the next clamping and positioning. The equipment frame 1 is equipped with a position adjustment component 8 for adjusting the position of the workpiece 2. A linkage locking component 7 for locking the hollow seat 302 is provided between the hollow seat 302 and the guide rail 301. The position adjustment component 8 is used to fix the main body of the workpiece 2 (excluding the end area of ​​the workpiece 2) and adjust the position of the workpiece 2 so that the end of the workpiece 2 can enter the working area of ​​the inner pressing component 3 and the outer pressing component 4. The linkage locking component 7 is used to lock the hollow seat 302 to prevent the hollow seat 302 from moving when it is not necessary to move it. The linkage locking assembly 7 includes a socket plate 701 and a connecting arm 702. The socket plate 701 is fixed inside the guide rail 301. One end of the connecting arm 702 is hinged to the outer edge of the disc 3055, and the other end is hinged to a rod 703. The rod 703 movably passes through the inner wall of the hollow seat 302. The rod 703 and the lifting rod 303 are symmetrically arranged, one above the other. The rod 703 is inserted into the socket on the socket plate 701. By inserting one end of the rod 703 into the socket, the locking mechanism is engaged. The rod 703 is limited along the axial direction of the guide rail 301, thereby limiting the hollow seat 302 along the axial direction of the guide rail 301. When the disc 3055 rotates, it synchronously drives the connecting arm 3056 and the connecting arm 702 to move, thereby simultaneously driving the lifting rod 303 and the insertion rod 703 to move. When the lifting rod 303 retracts, the insertion rod 703 also retracts, thereby realizing that when it is necessary to move the hollow seat 302, the insertion rod 703 retracts and disengages from the insertion hole, releasing the lock on the hollow seat 302. Welding assembly 9 includes a sliding plate 901, one end of which is slidably disposed in the guide rail 301. A welding torch 902 is fixedly disposed on the outer wall of the sliding plate 901. The sliding plate 901 extends toward the push rod 304 to the outside of the hollow seat 302. The sliding plate 901 is used to install the welding torch 902 and push the push rod 304. The welding torch 902 is used to weld the end of the workpiece 2. The positioning component 6 includes a hollow base 601. The outer wall of the hollow base 601 facing away from the end of the workpiece 2 is fixedly connected to the lifting rod 303. A connecting rod 602 is provided inside the hollow base 601. A threaded rod 605 is rotatably connected to the hollow base 601 through a bearing. An internal threaded block 606 is threadedly fitted onto the outer wall of the threaded rod 605. The internal threaded block 606 is a rectangular block and movably penetrates the outer wall of the hollow base 601. Three connecting rods 602 are provided on the same hollow base 601. The two connecting rods 602 on the left and right are fixedly connected to the hollow base 601, and the middle connecting rod 602 is connected to the internal threaded block. A fixed connection is made at 606. A rigid head 603 is fixed at one end of the connecting rod 602 away from the hollow seat 601. A silicone pad 604 is fitted on the outer wall of the rigid head 603. The silicone pad 604 serves as an elastic structure of the positioning element 6, increasing the contact area between the rigid head 603 and the end of the workpiece 2, as well as the static friction force, thereby improving the stability of the positioning element 6 in clamping and positioning the end of the workpiece 2. By rotating the threaded rod 605, the inner threaded block 606 moves axially along the threaded rod 605, thereby driving the middle connecting rod 602 to move and adjusting the height difference between the middle rigid head 603 and the left and right rigid heads 603, thus adapting to workpieces 2 with different curvatures. The lifting mechanism 5 includes a bidirectional electric slide rail 501, a bidirectional electric slide rail 502, and a lifting plate 503. The bidirectional electric slide rails 501 and 502 are fixedly installed inside the equipment frame 1. Two sets of lifting plates 503 are provided, one set connected to the inner pressing component 3 and the other set connected to the outer pressing component 4. The moving ends of the bidirectional electric slide rails 501 and 502 are respectively fixedly connected to the two sets of lifting plates 503. The lifting mechanism 5 also includes a limiting slide rail 504. The sliding end of the rail 504 is fixedly connected to the lifting plate 503. The limiting rail 504 increases the support and limit of the lifting plate 503, and prevents the position of the lifting plate 503 from shifting during the lifting process. Both bidirectional electric rail 1 501 and bidirectional electric rail 2 502 are composed of rails, motors, bidirectional lead screws and two sliders. The sliders are the moving ends of bidirectional electric rail 1 501 and bidirectional electric rail 2 502. The sliders are threaded on the bidirectional lead screws and slide inside the rails. The motor drives the bidirectional lead screws to rotate. The position adjustment assembly 8 is provided in four sets. Each position adjustment assembly 8 includes a telescopic cylinder 801, which is fixedly connected to the equipment frame 1. A U-shaped frame 802 (U-shaped bracket) is fixedly mounted on the telescopic end of the telescopic cylinder 801. A rotating shaft 803 is rotatably connected to the inner side of the U-shaped frame 802 via a bearing. Guide wheels 804 are fitted onto the rotating shaft 803, with two guide wheels 804 on the same rotating shaft 803, one in front and one in back. The two guide wheels 804 respectively block the front and rear of the workpiece 2. A fixing nut 805 is threaded onto the rotating shaft 803, fixing the guide wheels 804 to the rotating shaft 803. The four sets of position adjustment assemblies 8 clamp and fix the workpiece 2 from four positions, ensuring stability. The telescopic cylinder 801 extends and retracts, causing the U-shaped frame 802 to move, which in turn moves the rotating shaft 803. The movement of the rotating shaft 803 moves the guide wheels 804, allowing the guide wheels 804 to align with the workpiece. The edge contact of 2 is adjusted by turning the fixing nut 805 to adjust the position of the fixing nut 805, thereby adjusting the position of the guide wheel 804, so that the two guide wheels 804 on the same rotating shaft 2 803 simultaneously abut against the front and back of the workpiece 2, which plays a role in limiting the workpiece 2. The four telescopic cylinders 801 and the two-way electric slide rail 1 501 and two-way electric slide rail 2 502 are all controlled by an external controller. An auxiliary telescopic rod 13 is fixedly provided inside the equipment frame 1. The telescopic end of the auxiliary telescopic rod 13 is fixedly connected to the U-shaped frame 802. The auxiliary telescopic rod 13 supports and guides the U-shaped frame 802 to prevent the U-shaped frame 802 from shifting when it moves. A mounting seat 806 is fixedly provided inside the equipment frame 1. The telescopic cylinders 801 and the auxiliary telescopic rod 13 are fixedly connected to the mounting seat 806. The mounting seat 806 provides support and fixing parts for the telescopic cylinders 801 and the auxiliary telescopic rod 13, ensuring that the telescopic cylinders 801 and the auxiliary telescopic rod 13 are stably installed. A push plate 12 is fixed to one end of the push rod 304 that extends outside the hollow seat 302. The push plate 12 is directly opposite the sliding plate 901. The push plate 12 increases the contact area between the push rod 304 and the sliding plate 901 or other push rods 304, and at the same time, it can prevent the push rod 304 from being pushed entirely into the hollow seat 302.

[0022] Working principle: In use, first, according to the size of workpiece 2, tighten the fixing nut 805 to adjust the position of the guide wheel 804, open the four sets of telescopic cylinders 801, adjust the position of the four sets of U-shaped frames 802, align workpiece 2 with the space between the guide wheels 804 and insert it. Then, simultaneously open the four sets of telescopic cylinders 801, synchronously adjust the position of the U-shaped frames 802, and thus adjust the position of workpiece 2 so that the ends of workpiece 2 to be welded are aligned. Then, open the bidirectional electric slide rail one 501 and bidirectional electric slide rail two 502 to adjust the position of the lifting plate 503, and then adjust the inner pressing component 3 and the outer pressing component 3. The position of the pressing component 4 is such that the positioning member 6, which is connected to the inner pressing component 3 and the outer pressing component 4, clamps the end of the workpiece 2, thereby clamping and positioning the end of the workpiece 2. Manually pushing the sliding plate 901 moves the welding torch 902, causing the welding torch 902 to move along the end of the workpiece 2. During this movement, the sliding plate 901 pushes the push plate 12, which in turn pushes the push rod 304 (similarly, the welding component 9 corresponding to the outer pressing component 4 will also push the push rod corresponding to the outer pressing component 4; to avoid repetition, this embodiment only describes the case where the push rod 304 corresponding to the inner pressing component 3 is pushed). Rod 304 drives rack 3054 to move, rack 3054 moves and drives gear 3053 to rotate, gear 3053 rotates and drives shaft 3052 to rotate, which in turn drives disk 3055 to rotate. Disk 3055 rotates and pulls connecting arm 3056 and connecting arm 702 to move, which in turn pulls lifting rod 303 and insert rod 703 to retract into hollow seat 302. Insert rod 703 disengages from the insertion hole of insert plate 701. Lifting rod 303 moves and drives corresponding positioning part 6 to move, so that silicone pad 604 no longer tightly presses against the end of workpiece 2, so that hollow seat 302... The welding assembly 9 can be moved by pushing, and then welding can be performed on the part. As the welding assembly 9 continues to move, it will continue to push the push rod 304 corresponding to the first hollow seat 302 to continue moving. The push rod 304 moves and contacts the push rod 304 corresponding to the next hollow seat 302, and then pushes this push rod 304 to move, so that the positioning part 6 corresponding to the hollow seat 302 moves and separates from the workpiece 2. Then the hollow seat 302 is pushed, and the clamped and positioned part on the workpiece 2 is exposed. The welding assembly 9 moves and welds until the end of the workpiece 2 is welded.
