Description
Technical Field
[0001] The utility model relates to the technical field of welding, and particularly relates to a positioning welding tooling. Background Art
[0002] Welding is an important technology for connecting metals or other thermoplastic materials and has extensive applications in modern industry. When there are certain angular requirements for the welding positions of workpieces, the welding angle is usually controlled by manual operation and positioning, relying on intuition and feeling, and it is impossible to accurately control the welding angle, which easily causes the scrapping of the welded products.
[0003] Currently, during the production process, the corresponding corrugated wire 1 of the present application is as Figure 1 shown. The corrugated wire 1 includes an annular main body 11, and a notch 110 is provided on the annular main body 11. Since the corrugated wire 1 is corrugated, it has a thin thickness, a narrow width, and certain elasticity. Most of the current welding toolings are placed horizontally with the workbench. During welding, the welding torch angle needs to be adjusted to be perpendicular to the surface of the welding part to ensure the welding quality at the welding point. When laser welding is used, the direction of the welding laser beam is perpendicular to the welding tooling. If the existing welding tooling is adopted, it is difficult for the welding laser beam to be perpendicular to the overlapping joints at both ends of the annular main body 11 near the notch 110, thus it is difficult to ensure the welding quality of the welded joints of the annular main body 11. Therefore, a positioning welding tooling is needed to facilitate the pre-welding positioning of the annular main body 11 and ensure the quality of the welded joints of the annular main body 11. Summary of the Utility Model
[0004] To overcome the deficiencies of the above-mentioned prior art, the utility model provides a positioning welding tooling, which solves the technical problem that it is difficult for the welding laser beam to be perpendicular to the overlapping joints at both ends of the annular main body near the notch.
[0005] To achieve the above object, the utility model is realized by the following technical solutions:
[0006] A positioning welding tooling for pre-welding positioning of corrugated wire includes a positioning seat, an adjusting base, and a pressing block assembly. The positioning seat is installed on the adjusting base. The corrugated wire includes an annular main body, and a notch is provided on the annular main body. The positioning seat is provided with a limiting groove with an upper opening, the annular main body is arranged in the limiting groove, the pressing block assembly covers and presses on the annular main body, the pressing block assembly is installed on the positioning seat, an operation opening is provided in the limiting groove, the operation opening is arranged on one side of the limiting groove, and both ends of the annular main body near the notch overlap at the operation opening. The adjusting base includes a fixed plate and a movable plate, the movable plate is rotatably and adjustably installed on the fixed plate, and the positioning seat is installed on the movable plate.
[0007] Based on the above structure, the principle of the positioning welding tooling is as follows: First, place the annular main body in the limiting groove, and the pressing block assembly covers the annular main body to prevent the annular main body from popping out of the positioning seat during the welding process; the adjusting base is used to adjust the posture of the welding point position of the annular main body to face the welding laser beam. The two ends of the annular main body near the notch are lapped at the working port. Then, rotate the adjusting moving plate to drive the annular main body and the positioning seat to rotate integrally around the axis of the rotation connection between the moving plate and the fixed plate. During the rotation process, the posture of the welding point position of the annular main body gradually becomes a horizontal state parallel to the fixed plate. When the welding laser beam is facing the welding point position of the annular main body, the direction of the welding laser beam is perpendicular to the posture of the welding point position of the annular main body. At this time, the positioning before welding of the annular main body is completed.
[0008] Further, in a positioning welding tooling of the present application, a set of top block assemblies is provided in the limiting groove. The set of top block assemblies is installed on the positioning seat, and the set of top block assemblies can be movably adjusted in the radial direction of the annular main body. As a preferred solution of the present application, a set of top block assemblies in the positioning welding tooling of the present application facilitates the positioning seat to limit annular main bodies of different sizes, improving the versatility of the positioning welding tooling. When the set of top block assemblies limits the annular main body, the outer edge of the annular main body abuts against the side surface of the top block assembly facing the annular main body.
[0009] Further, in a positioning welding tooling of the present application, the top block assembly includes: a top block and a locking component. A set of vertically penetrating guide grooves is provided on the positioning seat. The guide grooves extend along the radial direction of the annular main body. A pair of the guide grooves corresponds to a set of top block assemblies. The locking component is installed in the guide grooves. The locking component can be movably adjusted in the extending direction of the guide grooves. The locking component is used to lock the position of the top block on the positioning seat. When the locking component locks the top block and the positioning seat, the locking component axially locks the top block and the positioning seat, so that the top block and the positioning seat are axially closely attached. As a preferred solution of the present application, the locking component in the positioning welding tooling of the present application is used to lock the position of the top block on the positioning seat. The operator can make the end face of the top block near the annular main body abut against the outer edge of the annular main body according to the size of the annular main body, and then lock the top block at different positions on the positioning seat through the locking component to limit the annular main body.
[0010] Further, in a positioning welding tooling of the present application, the working port penetrates vertically. One side of the working port extends out of the side surface of the positioning seat to form an opening. As a preferred solution of the present application, the working port in the positioning welding tooling of the present application is the welding working port for the annular main body. The vertical penetration is mainly to prevent the welding laser beam from irradiating on the positioning seat and damaging the positioning seat.
[0011] Furthermore, a positioning and welding tooling in the present application further includes: a pair of positioning magnets. The positioning seat is provided with a pair of convex parts along the extending direction of the working opening. The pair of convex parts are respectively located on both sides of the working opening, and the pair of positioning magnets are respectively installed on the pair of convex parts. As a preferred solution of the present application, the pair of positioning magnets in a positioning and welding tooling of the present application are used to position the two ends of the annular main body near the notch, preventing the two ends of the annular main body near the notch from loosening during the welding process.
[0012] Furthermore, a positioning and welding tooling in the present application further includes: an adjusting mechanism. The adjusting mechanism is arranged between the fixed plate and the moving plate. The moving plate is pivotally connected to the fixed plate. The side of the fixed plate extends with a flap, and the flap is pivotally connected to the fixed plate. The rotation axis core of the flap is parallel to the rotation axis core of the moving plate. The adjusting mechanism includes: a column and a pair of limiting blocks. One end of the column is installed on the flap, and the pair of limiting blocks are sleeved on the column. The pair of limiting blocks can move and adjust along the extending direction of the column. The moving plate is provided with a chute with a width adapted to the radial dimension of the column, and the column is slidably arranged in the chute. The moving plate is located between the pair of limiting blocks, and the upper and lower ends of the moving plate respectively fit with the upper and lower ends of the pair of limiting blocks. As a preferred solution of the present application, the adjusting mechanism in a positioning and welding tooling of the present application is used to adjust the opening and closing angle between the fixed plate and the moving plate, so as to adjust the posture of the welding point position of the annular main body. When in use, first adjust the pair of limiting blocks to move the pair of limiting blocks away from the moving plate along the axial direction of the column respectively, and then rotate the moving plate to a suitable angle position. During the rotation of the moving plate, the column slides in the chute. Because one end of the column is installed on the flap, the column drives the flap to rotate around the pivot of the flap and the fixed plate towards the direction close to the moving plate. Then adjust the pair of limiting blocks to move towards the moving plate along the axial direction of the column respectively until the upper and lower surfaces of the moving plate respectively fit with the upper and lower ends of the pair of limiting blocks, completing the adjustment of the opening and closing angle between the fixed plate and the moving plate.
[0013] Furthermore, in a positioning and welding tooling of the present application, the pressing block assembly includes: a pressing block and a threaded fastener. The pressing block is detachably installed on the positioning seat. The threaded fastener passes through the pressing block, and the threaded fastener is located inside the annular main body. The threaded fastener is threadedly connected to the positioning seat. As a preferred solution of the present application, in a positioning and welding tooling of the present application, the pressing block is detachably installed on the positioning seat. After the annular main body is welded, the pressing block is removed from the positioning seat, which is convenient for taking out the annular main body.
[0014] It can be seen from the above technical solutions that the present utility model has the following beneficial effects:
[0015] The present utility model provides a positioning and welding tooling fixture. Before welding, the annular main body is limited by a limiting groove, so that both ends of the annular main body near the notch are lapped at the working opening. Then, the moving plate is rotated and adjusted to drive the attitude of the welding point position of the annular main body to rotate until it is perpendicular to the welding laser beam, thereby completing the positioning before welding of the annular main body and improving the quality of the welding point position of the annular main body.

During the rotation process, the posture of the welding point position of the annular body 11 gradually becomes a horizontal state parallel to the fixed plate 31. When the welding laser beam is directly opposite the welding point position of the annular body 11, the direction of the welding laser beam is perpendicular to the posture of the welding point position of the annular body 11.

The pair of positioning magnets 6 are used to position the two ends of the annular main body 11 near the notch 110, and prevent the two ends of the annular main body 11 near the notch 110 from loosening during the welding process. The pair of convex parts 21 are connected to the positioning seat 2, and the pair of convex parts 21 can be movably adjusted in the direction perpendicular to the extending direction of the operation port 200.
