Description

Technical Field

[0001] This invention relates to the field of clamping and positioning mechanism technology, and in particular to a quick clamping and positioning mechanism for metal welding workpieces. Background Technology

[0002] Hardware components are widely used in industrial fields such as automobile manufacturing, machinery and equipment, and new energy equipment. They are the basic connecting and load-bearing parts for the assembly of various equipment structures. Hardware components are mostly made of alloy steel and lightweight metal profiles. They are usually assembled and fixed by welding. Welding, as the core process of hardware component forming and processing, can firmly combine the scattered hardware components into an overall frame structure, ensuring the continuity of the overall structure and the integrity of the assembly.

[0003] A positioning device for welding and processing hardware machinery products, disclosed in publication number 217193615U, includes a motor, a base, and a positioning mechanism for clamping hardware workpieces. The base has a sliding groove, and a slider is movably connected inside the groove. A rack is provided on one side of the slider. The output end of the motor is connected to a rotating shaft, and a gear is connected to the rotating shaft. The gear meshes with the rack. A fixed plate is connected to one side of the base, and a connecting rod is rotatably connected inside the fixed plate. A placement frame is provided at one end of the connecting rod. A rotating rod is rotatably connected inside the slider. This invention, through the coordinated use of the motor, base, positioning mechanism, sliding groove, slider, rack, rotating shaft, gear, fixed plate, connecting rod, placement frame, rotating rod, rotating block, and limiting port, has the advantages of clamping and fixing hardware workpieces, facilitating the flipping of hardware workpieces, simplifying welding, and improving work efficiency.

[0004] There are still some problems when welding hardware parts.

[0005] Existing hardware pipe components are widely used in many industrial fields such as machinery and equipment, fluid transportation, and new energy supporting facilities. During the production process, pipe splicing and forming are completed through welding processes. In hardware pipe welding operations, clamping components are usually needed to position and fix the pipe components to ensure the stability of the welding operation. Currently, traditional pipe clamping structures mostly use screws and clamping blocks to tighten and fix the workpiece to limit the position. Since hardware pipe welding operations require continuous progressive feeding of the workpiece and continuous segmented welding, traditional screw-type clamping structures need to be repeatedly loosened and tightened during the operation to match the progressive displacement of the pipe. The operation steps are cumbersome, the process continuity is poor, and it greatly affects the convenience and processing continuity of pipe welding operations. Summary of the Invention

[0006] The purpose of this application is to provide a quick clamping and positioning mechanism for metal welding workpieces, which realizes the clamping plate on the clamping component to clamp and fix the pipe surface through the driving component. During the clamping process, the feeding component can progressively feed the pipe clamped by the clamping plate for welding, thereby improving the welding efficiency of metal pipes.

[0007] To achieve the above objectives, this application provides the following technical solution: a quick clamping and positioning mechanism for metal welding workpieces, comprising a base plate on which a welding machine is fixedly mounted, a limiting seat installed at the center of the base plate, and a pair of pulleys rotatably connected to the limiting seat; a clamping assembly disposed on the base plate for fixing the workpiece; a driving assembly disposed on the clamping assembly for cooperative use; and a feeding assembly disposed on the clamping assembly for pushing the workpiece.

[0008] Preferably, the clamping assembly includes a bracket, a bearing seat, a driven rod, and a limiting plate; the bracket is provided in pairs, and a bearing seat is fixedly connected to the inner side of the pair of brackets. A driven rod is movably inserted into the bearing seat. One end of the driven rod extends to the outside of the bracket, and the other end of the driven rod is fixedly connected to the limiting plate. A sliding groove is provided on the limiting plate, and a slider is slidably connected inside the sliding groove. The slider is fixedly connected to the sliding plate.

[0009] Preferably, a pivot pin is fixedly connected to the top of the slide plate, and a clamping plate is fixedly connected to the side of the slide plate away from the slider. An arc-shaped groove is provided on the clamping plate, and a rubber pad is installed on the inner wall of the arc-shaped groove.

[0010] Preferably, the drive assembly includes a cylinder, a docking seat, a first pin, and a linkage plate; the cylinder is installed at the top of one of the brackets, the telescopic end of the cylinder is fixedly connected to the docking seat, a pair of first pins are fixedly connected to the docking seat, and a linkage plate is rotatably connected to each pair of first pins.

[0011] Preferably, the other end of the linkage plate is rotatably connected to the second pin, the bottom end of the second pin is fixedly connected to the top plate, a docking plate is fixedly connected to one side of the bottom surface of the top plate, the bottom end of the docking plate is fixedly connected to the horizontal plate, and both ends of the horizontal plate are fixedly connected to the driven rod.

[0012] Preferably, the feeding assembly includes a frame, a drive motor, a spindle, and a turntable; the frame is mounted on top of another bracket, the drive motor is fixedly installed inside the frame, the output end of the drive motor is fixedly connected to the spindle, and the bottom end of the spindle extends to the bottom of the bracket and is fixedly connected to the turntable.

[0013] Preferably, a limiting post is fixedly connected to the turntable, a first collar is sleeved on the limiting post, a driven plate is fixedly connected to the outer surface of the first collar, and the other end of the driven plate is fixedly connected to the outer surface of the second collar.

[0014] Preferably, the second ring is rotatably connected to the positioning post, the bottom end of the positioning post is fixedly connected to the frame, and movable slots are provided through both ends of the frame, with the shaft pins slidably connected inside the movable slots.

[0015] In summary, the present invention has the following beneficial effects:

[0016] 1. This device uses a cylinder drive and a pin and linkage plate transmission to drive the driven rod to move horizontally. Relying on the sliding cooperation of the limit plate, slide groove and slider, it drives the two clamping plates to open and close synchronously, which can quickly realize the clamping and release of the pipe. The inner side of the clamping plate is equipped with a rubber pad, which can flexibly fit the outer wall of the hardware pipe, increase the clamping friction, and avoid rigid extrusion that could cause scratches on the pipe surface. This ensures the stable positioning of the pipe during the welding operation, effectively prevents the pipe from shifting or rotating, and improves the welding position accuracy.

[0017] 2. In this invention, a crank transmission structure is formed by a drive motor, main shaft, turntable, limit post, and driven plate to drive the frame to reciprocate. The frame pushes the slide plate along the slide groove of the limit plate with the help of the shaft pin, so as to realize the axial feeding of the pipeline in the clamping state. The slide groove and the slider form an adaptive sliding pair, so that the clamping plate can keep up with the pipeline while maintaining the clamping posture. The pipeline can be conveyed in a progressive manner without continuously loosening the clamp, eliminating the repeated locking and loosening process, simplifying the operation process, and improving the continuity of pipeline welding.

[0018] 3. In this invention, the clamping drive component and the feed drive component cooperate with each other to realize the functions of pipe positioning and clamping and intermittent progressive feeding, respectively. The two sets of mechanisms are driven independently but linked together, which can be adapted to the segmented continuous welding of hardware pipes. The entire transmission structure relies on mechanical linkage to achieve orderly action. The structure is compact and responds quickly, replacing the traditional screw repeated locking and loosening mode, greatly reducing the intensity of manual operation, and effectively improving the overall production efficiency of hardware pipe welding processing.

Detailed Implementation

[0028] 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.

[0029] Example: Reference Figure 1 - Figure 7The illustrated quick clamping and positioning mechanism for metal welding workpieces includes a base plate 100, on which a welding machine 101 is fixedly mounted. A limiting seat 102 is installed at the center of the base plate 100, and a pair of pulleys 103 are rotatably connected to the limiting seat 102. A clamping assembly 200 is disposed on the base plate 100 for fixing the workpiece. A driving assembly 300 is disposed on the clamping assembly 200 for use in conjunction with it. A feeding assembly 400 is disposed on the clamping assembly 200 for pushing the workpiece.

[0030] Specifically, it should be noted that the welding machine 101, cylinder 301, and drive motor 402 are all electrically connected through the control unit. Their specific working principles are based on existing technologies and will not be elaborated on here. The welding machine 101 is used to weld pipes.

[0031] As one embodiment of this example, the clamping assembly 200 includes a bracket 201, a bearing seat 202, a driven rod 203, and a limiting plate 204. A pair of brackets 201 are provided, with the bearing seat 202 fixedly connected to the inner side of each pair of brackets 201. The driven rod 203 is movably inserted into the bearing seat 202. One end of the driven rod 203 extends outside the bracket 201, and the other end of the driven rod 203 is fixedly connected to the limiting plate 204. The limiting plate 204 has a sliding groove 205, and a slider 206 is slidably connected inside the sliding groove 205. The slider 206 is fixedly connected to a sliding plate 207. A pin 208 is fixedly connected to the top of the sliding plate 207. A clamping plate 209 is fixedly connected to the side of the sliding plate 207 away from the slider 206. An arc-shaped groove 210 is provided on the clamping plate 209, and a rubber pad 211 is installed on the inner wall of the arc-shaped groove 210.

[0032] Specifically, the pipe is moved into the clamping assembly 200 by the pulley 103 on the limiting seat 102, and then the driven rod 203 is moved by the cylinder 301 on the drive assembly 300. One end of the driven rod 203 is fixedly connected to the limiting plate 204. The movement of the driven rod 203 pushes the limiting plate 204 to move. A groove 205 is provided on the limiting plate 204, and the slider 206 on the sliding plate 207 is slidably connected in the groove 205. The movement of the limiting plate 204 causes the sliding plate 207 to move, and then the clamping plates 209 on the sliding plate 207 will move closer to each other, so that the rubber pad 211 inside the arc groove 210 fits against the surface of the pipe for clamping and positioning.

[0033] As one embodiment of this invention, the drive assembly 300 includes a cylinder 301, a docking seat 302, a first pin 303, and a linkage plate 304. The cylinder 301 is installed at the top of one of the brackets 201. The telescopic end of the cylinder 301 is fixedly connected to the docking seat 302. A pair of first pins 303 are fixedly connected to the docking seat 302. A linkage plate 304 is rotatably connected to each of the pair of first pins 303. The other end of the linkage plate 304 is rotatably connected to a second pin 305. The bottom end of the second pin 305 is fixedly connected to a top plate 306. A docking plate 307 is fixedly connected to one side of the bottom surface of the top plate 306. The bottom end of the docking plate 307 is fixedly connected to a horizontal plate 308. Both ends of the horizontal plate 308 are fixedly connected to the driven rod 203.

[0034] Specifically, the driven rod 203 is moved, the cylinder 301 operates to push the docking seat 302 to move, the movement of the docking seat 302 causes the linkage plate 304 on the first pin 303 to push the top plate 306 on the second pin 305 to move, the top plate 306 is fixedly connected to the top of the docking plate 307, and the bottom of the docking plate 307 is fixedly connected to the horizontal plate 308, the movement of the top plate 306 causes the horizontal plate 308 on the docking plate 307 to move, thereby facilitating the horizontal plate 308 to drive the driven rod 203 to move horizontally.

[0035] As one embodiment of this invention, the feeding assembly 400 includes a frame 401, a drive motor 402, a main shaft 403, and a turntable 404. The frame 401 is mounted on top of another support 201. The drive motor 402 is fixedly installed inside the frame 401. The output end of the drive motor 402 is fixedly connected to the main shaft 403. The bottom end of the main shaft 403 extends to the bottom of the support 201 and is fixedly connected to the turntable 404. A limit post 405 is fixedly connected to the turntable 404. A first collar 406 is sleeved on the limit post 405. A driven plate 407 is fixedly connected to the outer surface of the first collar 406. The other end of the driven plate 407 is fixedly connected to the outer surface of a second collar 408. The second collar 408 is rotatably connected to a positioning post 409. The bottom end of the positioning post 409 is fixedly connected to a frame 410. Movable slots 411 are opened through both ends of the frame 410. A shaft pin 208 is slidably connected inside the movable slot 411.

[0036] Specifically, after the clamping plate 209 clamps and positions the pipe, when it is necessary to feed the pipe forward, the drive motor 402 on the frame 401 operates, causing the main shaft 403 to rotate. A turntable 404 is fixedly connected to the bottom end of the main shaft 403. The rotation of the main shaft 403 causes the turntable 404 to rotate, which in turn drives the limiting post 405 to rotate. The rotation of the limiting post 405, through the driven plate 407 on the first ring 406, drives the positioning post 409 on the second ring 408 to move, thus fixing the position. Positioning column 409 is fixedly connected to frame 410, and frame 410 is provided with movable groove 411. Shaft pin 208 is slidably connected inside movable groove 411. The movement of positioning column 409 causes frame 410 to push slide plate 207 on shaft pin 208 to move. The movement of slide plate 207 causes slider 206 to slide inside slide groove 205, which facilitates progressive feeding of the pipe. When frame 410 retracts, arc groove 210 on clamp plate 209 is disengaged from pipe surface by cylinder 301, which facilitates indirect progressive feeding of the pipe.

[0037] The working principle of this invention is as follows: When the driven rod 203 is moved, the cylinder 301 operates to push the docking seat 302 to move. The movement of the docking seat 302 causes the linkage plate 304 on the first pin 303 to push the top plate 306 on the second pin 305 to move. The top plate 306 is fixedly connected to the top of the docking plate 307, and the bottom of the docking plate 307 is fixedly connected to the horizontal plate 308. The movement of the top plate 306 causes the horizontal plate 308 on the docking plate 307 to move, thereby facilitating the horizontal plate 308 to drive the driven rod 203 to move horizontally.

[0038] The pipe is moved into the clamping assembly 200 by the pulley 103 on the limiting seat 102, and then the driven rod 203 is moved by the cylinder 301 on the drive assembly 300. One end of the driven rod 203 is fixedly connected to the limiting plate 204. The movement of the driven rod 203 pushes the limiting plate 204 to move. A groove 205 is provided on the limiting plate 204, and the slider 206 on the sliding plate 207 is slidably connected in the groove 205. The movement of the limiting plate 204 causes the sliding plate 207 to move, and then the clamping plates 209 on the sliding plate 207 will move closer to each other, so that the rubber pad 211 inside the arc groove 210 fits against the surface of the pipe for clamping and positioning.

[0039] After the clamping plate 209 clamps and positions the pipe, when it is necessary to feed the pipe forward, the drive motor 402 on the frame 401 operates, causing the main shaft 403 to rotate. A turntable 404 is fixedly connected to the bottom end of the main shaft 403. The rotation of the main shaft 403 causes the turntable 404 to rotate, which in turn drives the limiting post 405 to rotate. The rotation of the limiting post 405, through the driven plate 407 on the first ring 406, drives the positioning post 409 on the second ring 408 to move. 409 is fixedly connected to the frame 410, and the frame 410 has a movable groove 411. A shaft pin 208 is slidably connected inside the movable groove 411. The movement of the positioning column 409 causes the frame 410 to push the slide plate 207 on the shaft pin 208 to move. The movement of the slide plate 207 causes the slider 206 to slide inside the slide groove 205, which facilitates the progressive feeding of the pipe. When the frame 410 retracts, the arc groove 210 on the clamp 209 is disengaged from the pipe surface by the operation of the cylinder 301, which facilitates the indirect progressive feeding of the pipe.
