Description

Technical Field

[0001] This utility model relates to the field of water pipe processing technology, and in particular to a square machine water pipe welding positioning device. Background Technology

[0002] Square pipe welding machines are commonly used automated equipment in the water pipe processing industry. During the water pipe welding process, the water pipe must be precisely aligned with the corresponding connector before welding. Currently, the positioning operation in the square pipe welding process relies heavily on manual hand-held clamps or simple fixed clamps. Manual positioning requires operators to adjust the water pipe position based on experience, while fixed clamps are specialized structures designed for specific water pipe specifications. Both are currently the mainstream positioning methods in the industry.

[0003] Currently, when manual positioning is used, it is easily affected by the operator's experience and hand stability, resulting in large deviations in the coaxiality and parallelism of the water pipe and the connector. Subsequent welding is prone to problems such as incomplete welding, missing welding, or uneven weld joints, resulting in a low product qualification rate. Although some positioning devices integrate conductive functions, the conductive components are mostly made of ordinary metal materials, and the installation gaps are not precisely controlled. During the welding process, problems such as poor contact and resistance fluctuations are prone to occur, affecting the stability of the welding current and thus causing fluctuations in weld joint quality. Therefore, improvements are needed. Utility Model Content

[0004] The main purpose of this utility model is to provide a square water pipe welding positioning device and a pet water dispenser. It aims to solve the technical problems in the prior art where manual positioning is easily affected by the operator's experience and hand stability, resulting in large deviations in the coaxiality and parallelism of the water pipe and the connecting parts. This leads to problems such as incomplete welding, missing welding, or uneven weld joints in subsequent welding, resulting in low product qualification rate. Although some positioning devices integrate conductive functions, the conductive parts are mostly made of ordinary metal materials, and the installation gap is not precisely controlled. This can easily lead to problems such as poor contact and resistance fluctuations during the welding process, affecting the stability of the welding current and thus causing fluctuations in weld quality.

[0005] In order to achieve the above-mentioned utility model objectives, this utility model proposes a square machine water pipe welding positioning device, including a water nozzle positioning component and a water pipe positioning component. Both the water nozzle positioning component and the water pipe positioning component include a mounting base plate, an adjustable positioning plate, and a contour positioning guide post. The contour positioning guide post includes a faucet positioning guide post, a water pipe positioning guide post, a faucet positioning copper electrode, and a water pipe positioning copper electrode. The faucet positioning guide post is fixedly installed on one side of the adjustable positioning plate of the faucet positioning assembly, and the water pipe positioning guide post is fixedly installed on one side of the adjustable positioning plate of the water pipe positioning assembly. A contour center positioning protrusion is provided on one side of the faucet positioning guide post, and the faucet positioning copper electrode and the water pipe positioning copper electrode are respectively fixedly installed on one side of the faucet positioning guide post and the water pipe positioning guide post.

[0006] Furthermore, the adjustable positioning plate has at least two adjustment elongated holes at one end, and fasteners are inserted into the adjustment elongated holes. The adjustable positioning plate is detachably connected to the mounting base plate through the fasteners.

[0007] Furthermore, the contour positioning guide post is provided with at least three posts, which are respectively distributed on the adjustable positioning plates of the water nozzle positioning assembly and the water pipe positioning assembly.

[0008] Furthermore, the water nozzle positioning guide posts are symmetrically arranged on both sides of the contour center positioning protrusion, and the axis of the water nozzle positioning guide posts is parallel to the axis of the contour center positioning protrusion.

[0009] Furthermore, the top of the contour center positioning protrusion is a hemispherical positioning protrusion, and the radius of the hemispherical positioning protrusion is adapted to the radius of curvature of the inner wall of the mouth.

[0010] Furthermore, the contoured center positioning protrusion is detachably fixed to one side of the water nozzle positioning guide post by bolts.

[0011] Furthermore, the mounting base plate is made of steel plate.

[0013] Furthermore, the contour positioning guide post and the adjustable positioning plate are connected by threads, and the outer wall of the contour positioning guide post is provided with a locking nut.

[0014] Furthermore, the water pipe positioning guide post has an arc-shaped groove in the middle, and the inner diameter of the arc-shaped groove on the water pipe positioning guide post is adapted to the outer diameter of the water pipe to be welded.

[0015] Beneficial effects: 1. This utility model's square water pipe welding positioning device effectively solves the problems of low accuracy and poor versatility of traditional positioning methods through a precise contour-following positioning structure and adjustable design. It utilizes the hemispherical contour-following center positioning protrusion of the water nozzle positioning guide post, with the spherical radius matching the curvature of the water nozzle's inner wall. Secondly, the arc-shaped groove of the water pipe positioning guide post has an inner diameter matching the outer diameter of the water pipe to be welded.

[0024] Reference Figures 1-4 An embodiment of this utility model provides a square machine water pipe welding positioning device, including a water nozzle positioning component and a water pipe positioning component. Both the water nozzle positioning component and the water pipe positioning component include a mounting base plate 1, an adjustable positioning plate 2, and a contour positioning guide post 3. The contour positioning guide post 3 includes a faucet positioning guide post 501, a water pipe positioning guide post 502, a faucet positioning copper electrode 601, and a water pipe positioning copper electrode 602. The faucet positioning guide post 501 is fixedly installed on one side of the adjustable positioning plate 2 of the faucet positioning assembly, and the water pipe positioning guide post 502 is fixedly installed on one side of the adjustable positioning plate 2 of the water pipe positioning assembly. A contour center positioning protrusion 4 is provided on one side of the faucet positioning guide post 501. The faucet positioning copper electrode 601 and the water pipe positioning copper electrode 602 are respectively fixedly installed on one side of the faucet positioning guide post 501 and the water pipe positioning copper electrode 602. At least two adjustment elongated holes are provided at one end of the adjustable positioning plate 2, and fasteners are inserted into the adjustment elongated holes. The adjustable positioning plate 2 is connected to the mounting plate 502 by the fasteners. The base plate 1 is detachably connected. At least three contour positioning guide posts 3 are provided and are respectively distributed on the adjustable positioning plate 2 of the water nozzle positioning assembly and the water pipe positioning assembly. The water nozzle positioning guide posts 501 are symmetrically arranged on both sides of the contour center positioning protrusion 4, and the axis of the water nozzle positioning guide post 501 is parallel to the axis of the contour center positioning protrusion 4. The top of the contour center positioning protrusion 4 adopts a hemispherical positioning protrusion. The spherical radius of the hemispherical positioning protrusion is adapted to the curvature radius of the inner wall of the nozzle. The contour center positioning protrusion 4 is detachably fixed to one side of the water nozzle positioning guide post 501 by bolts. The middle part of the water pipe positioning guide post 502 is provided with an arc-shaped groove. The inner diameter of the arc-shaped groove opened in the water pipe positioning guide post 502 is adapted to the outer diameter of the water pipe to be welded. The contoured center positioning protrusion 4 is detachably fixed to the water tap positioning guide post 501 by bolts. The appropriate hemispherical positioning protrusion can be quickly replaced according to the specifications of the water tap to be processed, improving the adaptability of the device to different water taps. The arc-shaped groove in the middle of the water pipe positioning guide post 502 fits tightly with the outer diameter of the water pipe to be welded. With the distributed layout of at least three contoured positioning guide posts 3 on the adjustable positioning plate 2, the displacement of the water pipe can be restricted from multiple directions. The adjustable positioning plate 2 can be adjusted in the horizontal or vertical direction along the mounting base plate 1 by adjusting the long hole and fastener. After the fastener is tightened, the relative position of the adjustable positioning plate 2 and the mounting base plate 1 can be locked to meet the positioning requirements of water pipes and water taps of different lengths and diameters.

[0025] This embodiment achieves precise control of the coaxiality and parallelism of the water nozzle and water pipe through the synergistic effect of the hemispherical structure of the contour-following center positioning protrusion 4 and the arc-shaped groove of the water pipe positioning guide post 502, avoiding the reliance on experience in manual positioning and the influence of hand stability; at the same time, relying on the adjustment function of the adjustable positioning plate 2, it can adapt to workpieces of different specifications without changing special fixtures, greatly reducing the phenomena of false welding, missing welding and uneven weld joints, and significantly improving the product qualification rate.

[0026] Optionally, the adjustment elongated holes on the adjustable positioning plate 2 can be set as oblong holes, and the number can be increased to 3-4, further improving the stability of the adjustable positioning plate 2 after it is connected to the mounting base plate 1; the fasteners can be wing bolts, which can manually lock and unlock the position of the adjustable positioning plate 2 without the aid of tools, shortening the positioning adjustment time.

[0027] In one embodiment, the mounting base plate 1 is made of steel plate, the water tap positioning copper electrode 601 and the water pipe positioning copper electrode 602 are both made of high-purity copper, the contour positioning guide post 3 and the adjustable positioning plate 2 are connected by threads, and the outer wall of the contour positioning guide post 3 is provided with a locking nut.

[0028] The mounting base plate 1 is made of steel plate with a thickness of 8-12mm, which has sufficient structural strength to avoid deformation of the mounting base plate 1 due to vibration during welding, thereby ensuring positioning accuracy. The copper electrode 601 for water tap positioning and the copper electrode 602 for water pipe positioning have a purity of ≥99.95%. The high-purity copper material can reduce current transmission loss and ensure stable conductivity. The contour positioning guide post 3 and the adjustable positioning plate 2 are connected by fine thread. With the locking nut on the outer wall of the contour positioning guide post 3, the installation gap between the contour positioning guide post 3 and the adjustable positioning plate 2 is guaranteed to avoid positioning deviation due to excessive gap.

[0029] In this embodiment, the steel plate mounting base 1 ensures the overall structural stability of the device. The high-purity copper water tap positioning copper electrode 601 and water pipe positioning copper electrode 602 improve conductivity. Combined with the precise threaded connection between the contour positioning guide post 3 and the adjustable positioning plate 2, the problems of poor contact and resistance fluctuation of conductive components in traditional positioning devices are solved, and the weld quality stability is improved. At the same time, the locking nut can prevent the contour positioning guide post 3 from loosening during long-term use, thus extending the service life of the device.

[0030] Optionally, the surface of the mounting base plate 1 can be galvanized or powder coated to enhance rust resistance and adapt to the humid environment during welding operations; the surfaces of the water tap positioning copper electrode 601 and the water pipe positioning copper electrode 602 can be plated with a 5-10μm thick nickel layer to improve the wear resistance and oxidation resistance of the electrodes and reduce the decrease in conductivity caused by wear or oxidation.
