Description

Technical Field

[0001] The utility model relates to the technical field of welding jigs, in particular to a welding jig with precise welding points. Background Technique

[0002] Welding is a processing technology and connection method that makes two workpieces generate atomic bonding through heating, pressure or both. Welding is widely used, and can be used for both metals and non-metals. Welding of metals is widely used in industrial sectors such as machinery manufacturing, shipbuilding, aerospace, petrochemical, construction, and power because of its firm bonding, good sealing performance, and stable quality. The welding of non-metals did not appear until the 1920s, and then developed rapidly and was widely used in industrial technologies such as chemical industry, electrical appliances, instruments, radio, and atomic energy.

[0003] A welding jig is a jig used to ensure the size of the welded parts, improve the assembly accuracy and efficiency, and prevent welding deformation. It is mainly used to fix and position the welding workpieces to ensure stability and accuracy during the welding process. The classification of welding jigs mainly includes special jigs and general jigs. Special jigs are specially customized for a specific component production process. Therefore, when designing, basic clamping and positioning requirements such as positioning accuracy, stability, and system rigidity, as well as factors such as convenient loading, clamping, and disassembly of components, are fully considered to improve the efficiency of the production process. General jigs, such as modular combined jigs, have a wider application range.

[0004] However, for common welding jigs, when clamping two workpieces to be welded, the two workpieces need to be clamped separately, and then the jig is moved for positioning, making the positioning process of the welding points rather cumbersome. In view of this, this application proposes a welding jig with precise welding points. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a welding jig with precise welding points, which has the advantages of synchronous clamping and positioning, etc., and solves the problem that when clamping two workpieces to be welded, the two workpieces need to be clamped separately, and then the jig is moved for positioning, making the positioning process of the welding points rather cumbersome.

[0006] To achieve the above object, the utility model provides the following technical solution: A welding jig with precise welding points, including a mounting base, on the top of the mounting base, two supporting vertical plates are fixedly installed, a rotation mounting hole is opened on one side of the supporting vertical plate, a rotation assembly is rotatably installed inside the rotation mounting hole, and a positioning and clamping assembly is arranged between the two rotation assemblies;

[0007] The positioning and clamping assembly includes two fixing plates fixedly installed between the two rotating assemblies. The two fixing plates are parallel to each other. A screw rod passes through the opposite sides of the two fixing plates, and one end of the screw rod is rotatably installed with a clamping plate.

[0008] Furthermore, fixing nuts are fixedly installed on the opposite sides of the two fixing plates away from each other. The screw rod rotates through the fixing plate and is threadedly connected to the fixing nut. A control knob is fixedly installed at the end of the screw rod away from the clamping plate.

[0009] Furthermore, the rotating assembly includes a rotating sleeve rotatably installed inside the rotating installation hole. A rotating gear is fixedly installed on one side of the rotating sleeve. A through hole is provided inside the rotating sleeve and the rotating gear.

[0010] Furthermore, a workpiece passes through the through hole. Weld reserved grooves are provided on the opposite sides of the two clamping plates. The butt joint of the workpieces is aligned with the weld reserved grooves.

[0011] Furthermore, a rotating shaft is rotatably installed between the two supporting vertical plates. A connecting through hole is provided on one side of the supporting vertical plate.

[0012] Furthermore, both ends of the rotating shaft extend to the opposite sides of the supporting vertical plate through the connecting through hole. Synchronous gears meshing with the rotating gears are fixedly installed at both ends of the rotating shaft.

[0013] Furthermore, a driven gear is fixedly installed on the surface of the rotating shaft. A control motor is fixedly installed on the top of the installation base. A driving gear is fixedly installed on the output shaft of the control motor. The driving gear meshes with the driven gear.

[0014] Compared with the prior art, the present utility model provides a welding fixture with precise welding points, having the following beneficial effects:

[0015] 1. For the welding fixture with precise welding points, by arranging a positioning and clamping assembly between the two rotating assemblies, the two workpieces to be welded are respectively passed through the through holes, and then the screw rod is rotated by the control knob to drive the clamping plate to move towards the middle, clamping the workpieces between the two clamping plates. Through the long and straight clamping plates, while the two workpieces are clamped, they are in the same straight line, quickly positioning the workpieces, and solving the problem that when clamping two workpieces to be welded, it is necessary to clamp the two workpieces separately and then move the fixture for positioning, making the positioning process of the welding points relatively cumbersome.

[0016] 2. The welding fixture with precise welding points drives the driving gear to rotate through the control motor, drives the driven gear to rotate, drives the rotating shaft to rotate, drives the synchronous gear, and simultaneously drives two rotating components to rotate, enabling the positioning and clamping component to drive the workpiece to rotate, quickly turn over the workpiece, and facilitating welding of the other side of the workpiece, solving the problem that after welding one side, the worker needs to flip the workpiece, re-clamp it, and weld the other side of the workpiece.

[0024] Wherein, fixed nuts 421 are fixedly installed on the sides of the two fixed plates 41 away from each other. The screw rod 42 rotatably penetrates through the fixed plate 41 and is threadedly connected to the fixed nut 421. A control knob 422 is fixedly installed at one end of the screw rod 42 away from the clamping plate 43. By driving the screw rod 42 to rotate through the control knob 422, under the action of the fixed nut 421, the screw rod 42 moves up and down, driving the clamping plate 43 to move up and down.

[0025] Meanwhile, the rotating assembly 3 includes a rotating sleeve 31 rotatably installed inside the rotating installation hole 201. A rotating gear 32 is fixedly installed on one side of the rotating sleeve 31. Through holes 301 are formed inside the rotating sleeve 31 and the rotating gear 32.

[0026] Wherein, a workpiece 5 penetrates through the through hole 301. Weld reserved grooves 431 are formed on the opposite sides of the two clamping plates 43. The butt joint of the workpiece 5 is aligned with the weld reserved groove 431. The workpiece 5 is placed between the two clamping plates 43 after passing through the through hole 301. Then, by driving the screw rod 42 to rotate through the control knob 422, the two clamping plates 43 are driven to move towards the middle, clamping the workpiece 5 between the two clamping plates 43. Since the workpiece 5 is located between the two long and straight clamping plates 43, the two workpieces 5 are in the same straight line, facilitating welding.

[0027] Meanwhile, a rotating shaft 6 is rotatably installed between the two support vertical plates 2. Connecting through holes 202 are formed on one side of the support vertical plate 2.

[0030] When this embodiment is in use, the workpiece 5 is passed through the through hole 301 and placed between the two clamping plates 43. The workpiece 5 is clamped and positioned through the positioning and clamping assembly 4. Then, one side of the workpiece 5 is welded. After the welding is completed, the control motor 9 drives the rotating assembly 3 to rotate, driving the workpiece 5 to turn over, and welding the other side of the workpiece 5.
