Description

Technical Field

[0001] This utility model relates to the field of heating tube welding technology, and in particular to a welding positioning fixture and welding equipment. Background Technology

[0002] A combined heating element is an electrical component that converts electrical energy into heat energy. It has a metal tube as its outer shell (including stainless steel and copper tubes), with spiral heating alloy wires (nickel-chromium or iron-chromium alloy) evenly distributed along the central axis inside the tube. The gaps are filled with compacted magnesium oxide sand, which has good insulation and thermal conductivity. The two ends of the tube are sealed with silicone. This metal-clad heating element can heat air, metal molds, and various liquids.

[0003] In related technologies, combined heating tubes are formed by splicing multiple heating tubes and connecting rods and then spot welding them together. The common welding method involves multiple workers manually determining the position of each heating tube, and then welding is performed at the intersection of multiple heating tubes and connecting rods.

[0004] However, in actual welding work, if the worker's hand shakes or the positioning is inaccurate during positioning, and a weld point has already been formed, it is difficult to readjust the position afterward, resulting in poor product consistency and a high risk of producing defective products. Therefore, a welding positioning fixture and welding equipment are proposed. Utility Model Content

[0005] To address the issue of hand tremors during positioning or the potential impact on product welding quality caused by inaccurate positioning, this invention provides a welding positioning fixture and welding equipment.

[0006] This utility model provides a welding positioning fixture and welding equipment, adopting the following technical solution:

[0007] A welding positioning fixture and welding equipment are disclosed. The positioning fixture includes a worktable, a support base, a support plate, and a positioning plate. The support base is slidably mounted on the support base, and the support plate is slidably mounted on the support base. The positioning plate is fixedly mounted on the support plate. The top surface of the positioning plate has a positioning groove for placing a heating tube. The positioning plate has a connecting groove that runs horizontally through the positioning groove. A connecting rod is provided in the connecting groove. A connecting clip is provided at the intersection of the connecting groove and the positioning groove. The connecting clip is located above the connecting rod.

[0008] By adopting the above technical solution and setting the positioning plate, when positioning the heating tube, the connecting rod is first placed horizontally in the connecting groove, and then the two heating tubes to be combined are placed in the corresponding positioning groove. At this time, the intersection of the heating tube and the connecting groove will rest on the connecting rod. Then, the connecting clip is placed at the intersection of the heating tube and the connecting groove, so that the connecting clip is fitted on the heating tube and engaged with the connecting rod, thereby realizing the positioning of the heating tube, improving the stability of the heating tube during welding, eliminating the need to hold the heating tube by hand, and improving the welding quality.

[0009] Optionally, a notch is provided on one side of the positioning plate.

[0010] By adopting the above technical solution, the notch design facilitates the placement of the end of the heating element.

[0011] Optionally, a welding port for placing a connecting clip is provided at the intersection of the connecting groove and the positioning groove.

[0012] By adopting the above technical solution, welding can be easily performed at the weld joint.

[0013] Optionally, the top of the support base is provided with a sliding groove, and the bottom of the support plate is provided with a slider, which slides within the sliding groove.

[0014] By adopting the above technical solution, after the heating tube is positioned, the support plate can be pushed to slide along the slide groove, and the positioning plate can be slid above the pad.

[0015] Optionally, a screw is rotatably mounted inside the worktable, and a motor for driving the screw to rotate is fixedly mounted on one side of the worktable. The support seat is sleeved on the screw and threadedly connected to the screw.

[0016] By adopting the above technical solution, since there are multiple welding joints, during welding, the motor can be started to drive the screw to rotate, so that the screw drives the support seat to slide laterally, and the support seat drives the positioning plate to slide laterally, thereby moving the welding joints sequentially between the welding column and the welding rod for welding, thus improving welding efficiency.

[0017] Optionally, a guide rod parallel to the screw is fixedly installed inside the worktable, and the support seat is slidably sleeved on the guide rod.

[0018] By adopting the above technical solution, the support base can be guided.

[0019] Optionally, the welding equipment includes a fixed base disposed on one side of the workbench, a pad disposed on the fixed base, and a welding column fixedly installed on one side of the pad.

[0020] By adopting the above technical solution, when the welding column is aligned with the welding joint, the pad block drives the welding column to rise and abut against the bottom of the connecting rod.

[0021] Optionally, a cylinder is fixedly installed on the top of the fixed base, a lifting block is fixedly installed on the piston end of the cylinder, and two spaced welding rods are fixedly installed on one side of the lifting block.

[0022] By adopting the above technical solution, when the welding column and welding rod are aligned with the welding joint, the cylinder is activated to drive the lifting block to descend. The lifting block drives the welding rod to descend and abut against the top of the connecting clip. The welding column then works with the connecting clip and the connecting rod to weld and fix them together, thus achieving the combined welding of the heating tube.

[0023] In summary, this utility model has the following beneficial effects:

[0024] 1. This utility model, through the setting of the positioning plate, allows for the positioning of the heating tube. First, the connecting rod is horizontally arranged and placed in the connecting groove. Then, the two heating tubes to be combined are placed in the corresponding positioning grooves. At this time, the intersection of the heating tube and the connecting groove will rest on the connecting rod. Then, a connecting clip is placed in each welding joint so that the connecting clip is fitted on the heating tube and engages with the connecting rod, thereby achieving the positioning of the heating tube, improving the stability of the heating tube during welding, eliminating the need to hold the heating tube by hand, and improving the welding quality.

[0025] 2. This utility model, through the arrangement of a screw, motor, and guide rod, allows for multiple welding joints. During welding, the motor can be started to drive the screw to rotate, causing the screw to drive the support seat to slide laterally along the guide rod. This, in turn, causes the support seat to drive the positioning plate to slide laterally, thereby moving the welding joints sequentially between the welding column and the welding rod for welding, thus improving welding efficiency.

Then, the connecting clip 44 is placed in each welding port 46, so that the connecting clip 44 is fitted on the heating tube and engaged with the connecting rod 43, thereby positioning the heating tube, improving the stability of the heating tube during welding, eliminating the need to hold the heating tube by hand, and improving the welding quality.

[0034] The positioning plate 4 has a notch 45 on one side, which facilitates the placement of the end of the heating tube.

[0035] Reference Figure 1 and Figure 2The support base 2 has a groove 21 on its top, and a slider 31 is provided on the bottom of the support plate 3. The slider 31 slides within the groove 21. The welding equipment includes a fixed base 5 on one side of the workbench 1. A cylinder 53 is fixedly installed on the top of the fixed base 5.

With the arrangement of the screw 11, motor 12 and guide rod 13, since there are multiple welding joints 46, during welding, the motor 12 can be started to drive the screw 11 to rotate, so that the screw 11 drives the support seat 2 to slide laterally along the guide rod 13, so that the support seat 2 drives the positioning plate 4 to slide laterally, thereby moving the welding joints 46 sequentially between the welding column 52 and the welding rod 55 for welding, thus improving welding efficiency.

[0037] The implementation principle of this utility model is as follows: When positioning the heating tube, the connecting rod 43 is first placed horizontally in the connecting groove 42, and then the two heating tubes to be combined are placed in the corresponding positioning groove 41. At this time, the intersection of the heating tube and the connecting groove 42 will rest on the connecting rod 43. Then, the connecting clip 44 is placed in each welding joint 46, so that the connecting clip 44 is sleeved on the heating tube and engaged with the connecting rod 43, thereby positioning the heating tube. After positioning the heating tube, the support plate 3 can be pushed to slide along the slide groove 21, and the positioning plate 4 is slid above the pad block 51. When the welding column 52 and the welding rod 55 are aligned with the welding joint 46, the cylinder 53 is activated to drive the lifting block 54 to descend, and at the same time the pad block 51 rises. The pad block 51 drives the welding column 52 to rise and abut against the bottom of the connecting rod 43. The lifting block 54 drives the welding rod 55 to descend and abut against the top of the connecting clip 44, thereby welding and fixing the connecting clip 44 and the connecting rod 43, thereby realizing the combined welding of the heating tube.
