Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a vertical and horizontal tooling for longitudinal seam welding. Background Art

[0002] Since the longitudinal seams of different workpieces have different welding requirements, the dual-mode vertical and horizontal welding tooling can select horizontal or vertical state for welding according to the welding process of the workpiece, thereby improving the production efficiency of the enterprise.

[0003] When the existing vertical and horizontal welding tooling is in use, the process of changing the tooling from horizontal to vertical is mostly achieved by pushing the crossbeam to flip 90 degrees by the cylinder. However, when the equipment is in vertical welding mode, the equipment needs to resist gravity to maintain the stability of the welding head. Simply relying on the push and pull force of the cylinder to maintain the stability of the equipment crossbeam has a slightly insufficient weight-resistant design. In addition, the oil seal of the cylinder will fail due to long-term wear after long-term use, which reduces the performance of the cylinder, resulting in the crossbeam of the tooling to swing easily during the vertical welding process, affecting the welding quality of the workpiece. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a vertical and horizontal tooling for longitudinal seam welding, so as to solve the problem that the vertical and horizontal tooling for longitudinal seam welding in the prior art is slightly insufficient in weight resistance design when vertical welding is adopted, and as the performance of the cylinder decreases, the crossbeam of the tooling is prone to swing, affecting the welding quality of the workpiece.

[0005] The utility model is realized by the following technical solutions:

[0006] A vertical and horizontal tooling for longitudinal seam welding comprises a lower base and an upper base hingedly mounted on the top of the lower base, the lower base being fixedly connected to a diagonal seat in a rotation direction relative to the upper base, the diagonal seat being rotatably connected to a rotating shaft, a hook being fixedly connected to the circumferential surface of the rotating shaft, and a pull rod being fixedly connected to the upper base, and when the upper base is rotated ninety degrees around the top angle of the lower base, the hook is rotated to hook with the pull rod to diagonally pull the upper base.

[0007] Furthermore, the hook includes a rotating part fixedly connected to the rotating shaft, a first clamping part is fixedly connected to the circumferential surface of the rotating part, a second clamping part is rotatably connected to a side of the first clamping part close to the rotating part, and an extrusion mechanism is provided between the second clamping part and the rotating part to drive the first clamping part to approach the first clamping part to clamp the pull rod.

[0008] Furthermore, the extrusion mechanism includes a mounting block fixedly connected to the end surface of the rotating part, a first sliding hole is radially opened on the circumferential surface of the mounting block, a sliding rod is inserted in the first sliding hole, and the upper end of the sliding rod extends out of the first sliding hole;

[0009] A pushing component is disposed on the circumference of the slide rod, and the slide rod continuously pushes the second clamping portion against the bottom of the pull rod under the action of the pushing component;

[0010] The lower end of the slide rod is provided with a toggle component for toggle the slide rod to slide into the first slide hole and restrict the upper end of the slide rod in the first slide hole.

[0011] Furthermore, a second sliding hole is provided in the mounting block, a center line of the second sliding hole coincides with a center line of the first sliding hole, and a diameter of the second sliding hole is larger than a diameter of the first sliding hole; a first push block is fixedly connected to the circumference of the sliding rod, and a spring is installed between the first push block and the bottom wall of the second sliding hole.

[0012] Furthermore, a slide groove is provided on the end surface of the mounting block, and the slide groove is connected to the first slide hole; the toggle component includes a toggle rod inserted in the slide groove, one end of the toggle rod passes through the slide groove, extends into the first slide hole and is fixedly connected to the slide rod, and a limiting groove is also provided on the end surface of the mounting block, and the limiting groove is connected to the slide groove, and the two are perpendicular to each other.

[0013] Furthermore, the extrusion mechanism also includes a limiting rod fixedly connected to the upper end of the sliding rod, the second clamping portion is provided with a through hole, the diameter of the through hole is larger than the diameter of the limiting rod, and the free end of the limiting rod passes through the through hole and extends to the inner side of the second clamping portion; a limiting hole with a diameter matching the diameter of the limiting rod is provided on the circumferential surface of the pull rod, and a connecting component is provided on the limiting rod; when the sliding rod extends out of the first sliding hole under the action of the pushing component, the free end of the limiting rod is pushed into the limiting hole, and the limiting rod pushes the second clamping portion to deflect and clamp the pull rod through the connecting component.

[0014] Furthermore, the second clamping portion is also provided with a third sliding hole, the center line of the third sliding hole coincides with the through hole, and the diameter of the third sliding hole is larger than the diameter of the through hole; the connecting component includes a second push block, the second push block is fixedly connected to the circumferential surface of the limiting rod, and the diameter of the second push block is between the through hole and the third sliding hole.

[0016] The beneficial effects of the utility model are:

[0017] When the welding tool is transformed from a horizontal state to a vertical state, the upper base is deflected between the lower base under the push of the oil cylinder. When the right end face of the upper base is against the top of the inclined pull seat, the upper base just rotates ninety degrees around the top angle of the lower base. At this time, the longitudinal seam welding tool is completed from a horizontal state to a vertical state. Then, the hook is rotated to hook the pull rod to obliquely pull the upper base, so as to cooperate with the force generated by the oil cylinder to make the upper base stably stand upright above the lower base, thereby improving the ability of the welding equipment to resist gravity. In addition, by obliquely pulling the upper base, the swing of the crossbeam of the tooling during the welding process can be effectively avoided, thereby ensuring the welding quality of the workpiece.

[0018] Secondly, when the welding tool is in a vertical state, the upper base is tilted so that the upper base can stand stably above the lower base. At this time, the crossbeam of the welding tool is also changed from horizontal to vertical, and the installation space of the cylinder is exposed, which is conducive to the staff to carry out maintenance and other work on the cylinder on the side of the welding tool.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0029] In addition, the term "same" does not mean that the mechanisms must be absolutely identical, but slight differences are allowed. The term "vertical" simply means that the positional relationship between the mechanisms is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0030] See also Figures 1 to 3The utility model provides a technical solution: a vertical and horizontal tooling for longitudinal seam welding, comprising a lower base 1 and an upper base 2 hingedly installed on the top of the lower base 1, the lower base 1 is fixedly connected with an inclined pull seat 3 in the rotation direction relative to the upper base 2, the inclined pull seat 3 is rotatably connected with a rotating shaft 6, and a hook is fixedly connected to the circumferential surface of the rotating shaft 6, and the upper base 2 is fixedly connected with a pull rod 5, and the side surfaces of the inclined pull seat 3 and the upper base 2 are both provided with semicircular grooves 4, and the hook and the pull rod 5 are respectively installed in the two semicircular grooves 4, which can reduce the installation space occupied by the hook and the pull rod 5; when the upper base 2 is rotated ninety degrees around the top angle of the lower base 1, the end face of the upper base 2 abuts against the top of the inclined pull seat 3, and the two semicircular grooves 4 are spliced ​​into a circular groove, at this time, the hook is rotated to hook the pull rod 5 to obliquely pull the upper base 2.

[0031] In this solution, when the welding tool is transformed from horizontal to vertical, the upper base 2 is deflected between the lower base 1 under the push of the cylinder. When the right end face of the upper base 2 is against the top of the inclined seat 3, the upper base 2 is just rotated ninety degrees around the top angle of the lower base 1. At this time, the longitudinal seam welding tool is completed from horizontal to vertical. Then the hook is rotated to hook the pull rod 5 to obliquely pull the upper base 2, so as to cooperate with the force generated by the cylinder to make the upper base 2 stand stably above the lower base 1, thereby improving the ability of the welding equipment to resist gravity. In addition, by obliquely pulling the upper base 2, the swing of the crossbeam of the tooling during welding can be effectively avoided, thereby ensuring the welding quality of the workpiece.

[0032] Secondly, when the welding tool is in a vertical state, the upper base 2 is tilted so that the upper base 2 stands stably above the lower base 1. At this time, the crossbeam of the welding tool is also changed from horizontal to vertical, and the installation space of the cylinder is exposed, which is conducive to the staff to repair the cylinder on the side of the welding tool.

[0034] In the present solution, when the hook is rotated to hook with the pull rod 5, the second clamping part 10 is driven by the extrusion mechanism to swing close to the first clamping part 9, so that the hook is hooked with the pull rod 5 to improve the stability of the hook during use, and prevent the hook from easily rotating and separating from the pull rod 5, thereby ensuring that the hook and the pull rod 5 continue to cooperate to obliquely pull the upper base 2.

[0035] See also Figure 2 and Figure 3 In this embodiment, the extrusion mechanism includes a mounting block 11 fixedly connected to the end surface of the rotating portion 8, a first sliding hole 12 is radially opened on the circumference of the mounting block 11, a sliding rod 13 is inserted into the first sliding hole 12, and the upper end of the sliding rod 13 extends out of the first sliding hole 12;

[0036] The circumferential surface of the slide rod 13 is provided with a pushing component, and the slide rod 13 continuously pushes the second clamping portion 10 against the bottom of the pull rod 5 under the action of the pushing component;

[0037] A shifting component is disposed at the lower end of the slide rod 13 , which is used to shift the slide rod 13 into the first slide hole 12 and restrict the upper end of the slide rod 13 in the first slide hole 12 .

[0038] In this solution, the sliding rod 13 can be pushed by the pushing component to be in a state of continuously extending out of the first sliding hole 12, and when the sliding rod 13 extends into the first sliding hole 12 under the action of the pushing component, the sliding rod 13 pushes the second clamping part 10 to swing close to the pull rod 5, thereby clamping the pull rod 5 between the first clamping part 9 and the second clamping part 10, and the sliding rod 13 can be pushed by the toggle component to slide back into the first sliding hole 12, and at this time, the first clamping part 9 and the second clamping part 10 can be separated from the pull rod 5 by rotating the hook, and the welding tooling can be transformed from vertical to horizontal under the action of the cylinder.

[0039] See also Figure 3 In this embodiment, a second sliding hole 14 is further provided in the mounting block 11, the center line of the second sliding hole 14 coincides with the center line of the first sliding hole 12, and the diameter of the second sliding hole 14 is larger than the diameter of the first sliding hole 12; a first push block 15 is fixedly connected to the circumference of the sliding rod 13, and a spring 16 is installed between the first push block 15 and the bottom wall of the second sliding hole 14.

[0040] In the present solution, the first push block 15 is pushed to slide along the wall of the second sliding hole 14 by the deformation of the spring 16, and the sliding of the first push block 15 drives the sliding rod 13 to slide, so that the sliding rod 13 extends into the first sliding hole 12 under the action force generated by the deformation of the spring 16, and pushes the second clamping part 10 to continuously abut against the pull rod 5 and cooperate with the first clamping part 9 to clamp the pull rod 5.

[0041] See also Figure 3 and Figure 4 In this embodiment, a slide groove 17 is provided on the end surface of the mounting block 11, and the slide groove 17 is connected to the first slide hole 12; the toggle component includes a toggle rod 18 inserted in the slide groove 17, one end of the toggle rod 18 passes through the slide groove 17 and extends into the first slide hole 12 and is fixedly connected to the slide rod 13, and a limiting groove 19 is also provided on the end surface of the mounting block 11, and the limiting groove 19 is connected to the slide groove 17, and the two are perpendicular to each other.

[0042] In the present embodiment, the slide bar 13 can be pushed into the first slide hole 12 by the toggle rod 18, and the slide groove 17 provides a sliding space for the movement of the toggle rod 18. When the toggle rod 18 slides to the bottom wall of the slide groove 17, the toggle rod 18 is rotated so that the toggle rod 18 is offset into the limiting groove 19. At this time, the limiting groove 19 limits the toggle rod 18 so that the upper end of the slide bar 13 is continuously restricted in the first slide hole 12, and the spring 16 is in a compressed state at this time. When the toggle rod 18 is pushed back into the slide groove 17, the slide bar 13 automatically extends out of the first slide hole 12 again under the force generated by the deformation of the spring 16, and pushes the second clamping portion 10 to abut against the pull rod 5.

[0043] See also Figure 3 In this embodiment, the extrusion mechanism also includes a limiting rod 20 fixedly connected to the upper end of the sliding rod 13, and the second clamping portion 10 is provided with a through hole 21, the diameter of the through hole 21 is larger than the diameter of the limiting rod 20, and the free end of the limiting rod 20 passes through the through hole 21 and extends to the inner side of the second clamping portion 10; a limiting hole 22 with a diameter matching the diameter of the limiting rod 20 is provided on the circumferential surface of the pull rod 5, and a connecting component is provided on the limiting rod 20; when the sliding rod 13 extends out of the first sliding hole 12 under the action of the pushing component, the free end of the limiting rod 20 is pushed into the limiting hole 22, and the limiting rod 20 pushes the second clamping portion 10 to deflect and clamp the pull rod 5 through the connecting component.

[0044] In this solution, when the sliding rod 13 extends out of the first sliding hole 12 under the force generated by the deformation of the spring 16, the sliding rod 13 drives the limiting rod 20 to move, so that the upper end of the limiting rod 20 extends into the limiting hole 22 of the pull rod 5, further limiting the pull rod 5, so that the hook and the pull rod 5 are stably hooked together. At the same time, when the upper end of the limiting rod 20 extends into the limiting hole 22, the limiting rod 20 pushes the second clamping part 10 to deflect through the connecting part, so that the second clamping part 10 cooperates with the first clamping part 9 to clamp the pull rod 5.

[0046] In this solution, when the limit rod 20 slides into the limit hole 22, the limit rod 20 drives the second push block 24 to move, so that the second push block 24 pushes the second clamping part 10 to swing, so that when the slide rod 13 extends into the first slide hole 12 under the action force generated by the deformation of the spring 16, it can push the second clamping part 10 to swing and cooperate with the first clamping part 9 to clamp the pull rod 5, and at the same time, it can push the upper end of the limit rod 20 to extend into the limit hole 22 of the pull rod 5, thereby realizing that the hook is stably hooked to the outside of the pull rod 5, and the upper base 2 is obliquely pulled.
