Description

Technical Field

[0001] This invention relates to the field of bathroom accessory welding technology, and more specifically, to a welding apparatus and processing method for bathroom accessories. Background Technology

[0002] Bathroom accessories (such as towel racks, towel rings, and shelves) are home hardware products with distinct market characteristics: a wide variety of products and rapid design updates, but order quantities for individual models are typically small. This market characteristic makes it difficult to adopt large-scale, fully automated production lines with customized molds for single products, as the high mold costs are difficult to amortize in small-batch production.

[0003] Currently, the common processing method in this field is as follows: for the welding process of specific hanging parts, special positioning fixtures are designed and manufactured. Operators manually place the various parts to be welded (such as pipes, brackets, bases, etc.) into the fixtures for positioning and clamping, and then weld them point by point using a hand-held welding torch or operating semi-automatic welding equipment. This "special fixtures combined with manual welding" model is a common choice for adapting to small-batch flexible production.

[0004] However, this existing technical solution has the following inherent drawbacks: Poor consistency in welding quality and over-reliance on worker skills: Welding quality (such as weld point location, weld strength, and product appearance) is highly dependent on the operator's skill level, experience, and concentration during operation. Products welded by different workers or by the same worker at different times are prone to quality fluctuations, resulting in unstable product pass rates and making it difficult to achieve standardized output.

[0005] The trade-off between production efficiency and labor costs is prominent: to ensure welding quality, highly skilled welders are often required, resulting in high labor costs. Simple positioning fixtures cannot reduce the rigid demand for worker skills, creating a dilemma for companies balancing increasing automation, controlling overall costs, and ensuring product quality.

[0006] Therefore, the industry urgently needs a new type of welding equipment that can adapt to the characteristics of multi-variety, small-batch production of bathroom accessories, avoid the high cost of special molds, effectively reduce reliance on the individual skills of operators, improve the standardization and quality consistency of the welding process, and at the same time have good economy and ease of use, so as to solve the prominent contradictions between quality, cost and efficiency in the current production method. Summary of the Invention

[0007] (a) Technical problems to be solved To address the problems existing in the prior art, the present invention provides a welding device and processing method for bathroom accessories, thereby solving the technical problems mentioned in the background art.

[0008] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a welding device for processing bathroom accessories, comprising an adjustment mechanism and a spot welding mechanism; The adjustment mechanism is used to fix the horizontal tube during processing and welding at different positions on the hanger; The spot welding mechanism is used to spot weld the transverse pipe onto the hanger; The adjustment mechanism includes an overall positioning mechanism and a dual-tube positioning mechanism; The overall positioning mechanism is used to adjust the overall position of the bracket and to adjust the position between the dual-tube positioning mechanism and the overall positioning mechanism; The dual-tube positioning mechanism is used to adjust the distance between the two transverse tubes; The dual-tube positioning mechanism includes a synchronization mechanism and a limiting mechanism; The synchronization mechanism is used for simultaneous spot welding of multiple horizontal pipes and the bracket by multiple welding guns; The limiting mechanism is used to synchronously adjust the positions of multiple welding torches so that the bracket and multiple horizontal tubes can be adjusted to be in different states.

[0009] Preferably, the adjustment mechanism includes a semi-enclosed frame fixedly installed on an external device, with guide strips installed on both sides of the semi-enclosed frame. The dual-tube positioning mechanism slides along the guide strips, and the guide strips restrict the dual-tube positioning mechanism to slide only along the semi-enclosed frame.

[0010] Preferably, a sliding groove is provided on the inner wall opposite to the semi-enclosed frame, and the hanger is slidably connected in the sliding groove, so as to ensure that the hanger and the double tube positioning mechanism slide on the same axis.

[0011] Preferably, the overall positioning mechanism includes multiple positioning frames installed on the semi-enclosed frame. Each positioning frame is provided with a tail sleeve for limited rotation. An adjusting rod is threaded inside the tail sleeve. The adjusting rod is slidably connected inside the positioning frame. The relative position between the hanger and the semi-enclosed frame can be changed by adjusting the thread between the tail sleeve and the adjusting rod.

[0012] Preferably, the overall positioning mechanism is provided in multiple parts, and each of the multiple adjusting rods is provided with an adjusting block and a magnetic sleeve. The magnetic sleeve is slidably connected within the semi-enclosed frame, and the adjusting block is slidably connected to the guide strip for limiting.

[0013] Preferably, the dual-tube positioning mechanism includes a follower block that is slidably connected to the guide strip. A bidirectional screw is provided between the adjusting block and the follower block with reverse threads. Two fixing springs are symmetrically arranged at the middle position of the bidirectional screw. The two fixing springs abut against the adjusting block and the follower block respectively. The distance between the adjusting block and the follower block can be changed by the bidirectional screw, and the two fixing springs ensure that the relative positions of the adjusting block and the follower block are fixed after the position is changed.

[0014] Preferably, the synchronization mechanism includes lifting frames that are vertically slidably connected to the adjusting block and the follower block, and synchronization blocks are respectively limited and installed on the two lifting frames. A synchronization frame is slidably arranged between the two synchronization blocks, and top springs are respectively provided on both sides of the synchronization frame. The two top springs abut against the synchronization blocks. Intermediate sleeves are slidably arranged on the two lifting frames, and the two intermediate sleeves are slidably connected to each other by two transverse rods. A handle is fixedly arranged between the two transverse rods, and a vertical rod is installed on the handle. The vertical rod is limited and slidably connected inside the synchronization frame.

[0015] Preferably, the limiting mechanism includes movable magnetic blocks installed at the lower ends of the plurality of lifting frames and fixed magnetic sleeves installed at the lower ends of the intermediate sleeve. The upper and lower ends of the intermediate sleeve are respectively provided with tension springs and compression springs. The other end of the tension spring is fixedly connected to the lifting frame, and the other end of the compression spring is provided with a pressure plate. The intermediate sleeve is threaded with a tension bolt, and the other end of the tension bolt presses on the pressure plate. The fixed magnetic sleeve and the follower block and the adjusting block will generate a magnetic attraction force. The movable magnetic block and the follower block and the adjusting block will generate a magnetic attraction force. The magnitude of the magnetic attraction force can be changed by adjusting the distance. Each lifting frame is provided with a limiting frame. When welding the hanger and the transverse tube, the limiting frame is stuck on both sides of the transverse tube. When the hanger is being installed or disassembled, the limiting frame does not contact the transverse tube.

[0016] Preferably, the spot welding mechanism includes welding guns mounted on each of the lifting frames, the joint between the transverse tube and the hanging frame forms a joint, and the plurality of welding guns are located at the top of the joint.

[0017] This invention provides a welding method for processing bathroom accessories, comprising the following steps: Pre-positioning steps: Based on the size of the workpiece to be welded, pre-adjust the overall positioning mechanism to determine the lateral reference position of the hanger, and adjust the double-tube positioning mechanism to determine the welding center distance between the two lateral tubes; Workpiece loading steps: Insert the hanger into the slide groove of the device and fix it magnetically, and initially place the lateral tube in the corresponding position of the hanger; Linked positioning and welding steps: Press down the operating handle once to drive the synchronization mechanism to make the two welding gun carriers descend synchronously. During this process, the limiting mechanism first performs mechanical clamping and magnetic assisted fixation on the lateral tube to achieve precise positioning; Continue to press down to the working stroke, and the two welding guns synchronously press against the weld seam and perform spot welding; Reset and unloading steps: Release the handle, the welding parts automatically reset, and the workpiece is taken out. Through the simple operation of "one adjustment, one clamping, and one press down", the complex positioning, clamping, and welding actions are integrated into a continuous process, which significantly reduces the difficulty of operation and skill requirements.

[0018] (III) Beneficial Effects Compared with the prior art, the present invention provides a welding device and processing method for bathroom accessories, which has the following beneficial effects: Significantly improving the consistency and standardization of welding quality and completely reducing reliance on individual operator skills, this invention replaces manual visual positioning with a preset mechanical positioning mechanism (overall positioning mechanism and double-tube positioning mechanism), ensuring the accuracy and repeatability of the relative position of the bracket and the horizontal tube. Mechanical hard limiting is achieved through the limiting frame in the limiting mechanism, combined with magnetic assisted fixing, effectively preventing workpiece movement during welding. The entire positioning and clamping process is guaranteed by the mechanical structure of the device itself, and the welding position and downward stroke of the welding torch are fixed. Therefore, welding quality (weld point position, symmetry, penetration depth) is no longer affected by the operator's experience and condition, achieving standardized output in mass production and significantly improving the product qualification rate.

[0019] This device enables rapid and flexible switching between small-batch, multi-variety production, significantly reducing the cost of specialized tooling. Targeting the diverse types and small batches of bathroom accessories, this device abandons the traditional "one piece, one fixture" model. The distance between two welding points can be steplessly adjusted by rotating the bidirectional screw, and the reference position of the hanger can be set by adjusting the tail sleeve. One device can adapt to multiple different product models within minutes. This "adjustable" rather than "dedicated" design greatly reduces the costs of fixture development, manufacturing, and management caused by product upgrades, making small-batch flexible production economically feasible.

[0020] By optimizing ergonomics, simplifying operating procedures, improving production efficiency, and reducing labor intensity and training costs, this invention integrates the complex multi-step, high-skill process of "positioning, clamping, and welding" into a single, continuous "pressing down" action. Operators only need to complete the initial parameter preset, simple component assembly, and press the handle to complete the welding. This highly integrated, "foolproof" operation significantly reduces labor intensity, allowing ordinary workers to start working after brief training, reducing reliance on highly skilled welders, and comprehensively reducing the company's human resources and training costs.

[0021] The device has a compact structure, high reliability, and is easy to maintain. Its core functions are achieved through basic mechanical components such as screws, slides, springs, and magnets. The transmission chain is simple, with a low failure rate. Overload protection is achieved naturally through mechanical structures (such as spring buffers). It is highly resistant to the environment (oil, dust) and is suitable for typical hardware processing workshop environments. Daily maintenance only requires simple cleaning and lubrication, and the long-term operating cost is low. Attached Figure Description

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] This invention provides a welding device for processing bathroom accessories, particularly suitable for welding two horizontal pipes 12 to a long strip-shaped hanger 13 body (e.g., the longitudinal bar of a towel rack). This device, through a flexibly adjustable mechanical structure, replaces traditional special clamps, enabling rapid adaptation to different models and welding size requirements of accessory products, and achieving accurate positioning and synchronous welding, effectively reducing reliance on operator skills.

[0028] The welding device mainly includes an adjustment mechanism 11 and a spot welding mechanism 21.

[0029] The adjustment mechanism 11 is the core of this device for achieving flexible positioning. It is used to precisely fix the overall position of the bracket 13 according to the product drawings, and to adjust the welding positions of the two horizontal tubes 12 relative to the bracket 13 and the distance between the two horizontal tubes 12. The adjustment mechanism 11 is further divided into an overall positioning mechanism 31 and a double-tube positioning mechanism 41.

[0030] The spot welding mechanism 21 is used to perform the final welding operation. After the adjustment mechanism 11 has completed all positioning, it is triggered by the operator to simultaneously spot weld multiple welding points.

[0031] 1. The structure and positioning adjustment principle of the device 1.1 Basic Frame and Hanger Introduction The foundation of the adjustment mechanism 11 is a semi-enclosed frame 14 fixedly mounted on a workbench (not shown in the figure). Two parallel sliding grooves 16 are symmetrically formed on the inner side of the semi-enclosed frame 14, and the two side edges of the hanger 13 are slidably fitted into the sliding grooves 16. This design strictly limits the length direction of the hanger 13 after it is installed, allowing it to slide only in a straight line along the sliding grooves 16, providing an initial reference for subsequent lateral positioning. Guide strips 15, serving as horizontal guide rails, are fixedly installed on the outer walls of both sides of the semi-enclosed frame 14.

[0032] 1.2 Working Principle of the Overall Positioning Mechanism 31 The overall positioning mechanism 31 is used to fine-tune and ultimately lock the precise lateral position of the hanger 13 in the slide groove 16. It includes multiple positioning units spaced apart along the length of the semi-enclosed frame 14. Each positioning unit includes a positioning frame 32 fixed to the semi-enclosed frame 14. A tail sleeve 33 is rotatably disposed within the positioning frame 32 via bearings. The axial rotation of the tail sleeve 33 is restricted, allowing it to rotate only about its own axis. The front end of an adjusting rod 34 points towards the side wall of the hanger 13, and the rear end is threadedly connected to the tail sleeve 33. When the position of the hanger 13 needs to be adjusted, the operator rotates the tail sleeve 33. Due to the action of the threaded pair, the rotational motion is converted into the linear forward and backward motion of the adjusting rod 34, thereby pushing or pulling the hanger 13 to make slight movements within the slide groove 16. To achieve quick clamping, a magnetic sleeve 36 is connected to the front end of the adjusting rod 34. When the hanger 13 (usually made of ferromagnetic material) is adjusted to the target position and comes into contact with the magnetic sleeve 36, the magnetic force generated by the magnetic sleeve 36 can attract and fix it, completing the final positioning of the hanger 13. The tail end of one of the adjusting rods 34 also extends to form (or is fixedly connected to) an adjusting block 35, which is slidably sleeved on the guide bar 15, so that it can move laterally synchronously with the hanger 13.

[0033] 1.3 Spacing Adjustment and Locking of the Dual-Pipe Positioning Mechanism 41 The dual-pipe positioning mechanism 41 is used to set the welding center distance between the two transverse pipes 12. Its core includes an adjusting block 35 (linked with the overall positioning mechanism 31), a follower block 42, a bidirectional screw 43, and two fixing springs 44. The follower block 42 is also slidably mounted on the guide bar 15. The two sections of the bidirectional screw 43 are respectively machined with threads of opposite directions and screwed into the adjusting block 35 and the follower block 42 accordingly. Two fixing springs 44 are symmetrically mounted on the screw section between the two sliders, with their ends abutting against the adjusting block 35 and the follower block 42 respectively. When the operator rotates the bidirectional screw 43, the adjusting block 35 and the follower block 42 move towards or away from each other along the guide bar 15, allowing for stepless adjustment of the distance between them. After adjustment, the elastic force of the two fixed springs 44 provides a continuous axial preload to the adjusting block 35 and the follower block 42. This preload significantly increases the self-locking friction of the threaded pair and the static friction between the slider and the guide bar 15, thereby achieving reliable mechanical locking of the adjustment distance without additional locking devices, preventing displacement due to vibration during subsequent operations.

[0034] 1.4 Linkage Design of Synchronization Mechanism 51 and Limiting Mechanism 61 The upper part of the dual-tube positioning mechanism 41 integrates the synchronization mechanism 51 for driving the welding torch and the limiting mechanism 61 for performing precise positioning.

[0035] Synchronization Mechanism 51: A lifting frame 52 is vertically mounted on each of the adjusting block 35 and the follower block 42 via linear bearings. The upper parts of the two lifting frames 52 are connected by a synchronization frame 54. Specifically, a synchronization block 53 is fixed on each lifting frame 52, and the two ends of the synchronization frame 54 are engaged with the slide rails on the synchronization block 53 via sliders, allowing them to slide relative to each other in the horizontal direction. Two top springs 55 are installed between the synchronization frame 54 and the two synchronization blocks 53, keeping the synchronization frame 54 dynamically centered in the horizontal direction. Each of the two lifting frames 52 is also fitted with a vertically sliding intermediate sleeve 56, and the two intermediate sleeves 56 are connected by two transverse rods 57. A handle 58 for the operator to grip is fixed in the middle of the transverse rods 57. The upper end of a vertical rod 59 is fixed to the handle 58, and the lower end passes through the guide hole in the middle of the synchronization frame 54. This linkage structure ensures that when the operator moves the handle 58 up or down, the two lifting frames 52 can be raised and lowered vertically in strict synchronization through the transmission of the vertical rod 59, the synchronous frame 54, and the synchronous block 53; at the same time, in the horizontal direction, the sliding pair between the synchronous frame 54 and the synchronous block 53 allows the adjusting block 35 and the follower block 42 to freely adjust the distance without interfering with the vertical transmission.

[0036] Limiting mechanism 61: A movable magnetic block 62 is fixed at the lower end of each lifting frame 52, and a fixed magnetic sleeve 63 is fixed at the lower end of the corresponding intermediate sleeve 56. Both the movable magnetic block 62 and the fixed magnetic sleeve 63 can generate magnetic force to attract and fix the transverse tube 12 (ferromagnetic material). A tension spring 64 and a compression spring 65 are provided between the intermediate sleeve 56 and the lifting frame 52. The upper end of the tension spring 64 is connected to the lifting frame 52, and the lower end is connected to the intermediate sleeve 56, providing an upward restoring force for the intermediate sleeve 56. The upper end of the compression spring 65 rests on the step inside the intermediate sleeve 56, and the lower end transmits pressure through a pressure plate 66. The position of the pressure plate 66 can be adjusted by screwing the tension bolt 68 into the intermediate sleeve 56, thereby changing the preload of the compression spring 65. A pair of limiting frames 67 are also hinged to the lower part of each lifting frame 52. In the non-working state (when the lifting frame 52 is raised), the limiting frames 67 are open under their own weight or the action of the torsion spring.

[0037] 1.5 Spot Welding Mechanism 21 The spot welding mechanism 21 includes welding torches 22 respectively mounted on two lifting frames 52. The heads of the welding torches 22 are precisely calibrated so that when the lifting frames 52 descend to the welding position, the welding points of the two welding torches 22 can be accurately aligned with the two fitting seams 23 formed by the contact between the transverse tube 12 and the hanging frame 13.

[0038] 2. Operating procedures and methods of the device Based on the above structure, the welding apparatus of this embodiment operates according to the following steps: S1: Preparation and Parameter Preset: The operator performs two preset adjustments based on the product drawings of the component to be welded: Rotate the relevant tail sleeve 33, move the adjusting rod 34 and the magnetic sleeve 36 to determine the lateral installation position of the bracket 13.

[0039] Rotate the bidirectional screw 43 to adjust the distance between the follower block 42 and the adjusting block 35, and set the welding center distance of the two transverse tubes 12. After adjustment, each component is held in place by magnetic attraction, thread self-locking, and the preload of the fixing spring 44.

[0040] S2: Workpiece loading and initial positioning: Lift handle 58 upwards, causing the entire lifting frame 52, intermediate sleeve 56, and welding torch 22 to move upwards. At this time, the movable magnetic block 62 rises and approaches the adjusting block 35 and follower block 42, increasing the magnetic attraction and being attracted and fixed; simultaneously, the limiting frame 67 is fully raised, making room. Then, the hanger 13 is pushed in along the slide groove 16, so that its side wall is attracted and positioned by the magnetic sleeve 36. Next, the two horizontal tubes 12 are placed at the predetermined welding positions of the hanger 13, roughly between the two corresponding limiting frames 67 below.

[0041] S3: Final positioning and welding execution: Press the handle 58 downwards smoothly. The lifting frame 52 descends synchronously. First, the arc surface at the lower end of the limiting frame 67 contacts the transverse tube 12 and guides it until the limiting frame 67 is locked on both sides of the transverse tube 12, achieving mechanical limiting. At the same time, the movable magnetic block 62 and the fixed magnetic sleeve 63 descend close to the adjusting block 35 and the follower block 42, and are magnetically attracted to the adjusting block 35 and the follower block 42. At this time, the tip of the welding torch 22 approaches but does not contact the joint 23. After the operator confirms that the positioning is correct, continue to press the handle 58 down. During this stage, the tension spring 64 is stretched, while the compression spring 65 begins to be compressed. The lifting frame 52 continues to descend under the tension of the tension spring 64, driving the welding torch 22 to finally abut against the joint 23. The compression spring 65 is designed with a preload force to balance and optimize the contact pressure between the welding torch and the workpiece. After reaching the preset stroke or pressure, the welding torch 22 is energized, and the two spot welds are completed simultaneously.

[0042] S4: After resetting and unloading welding is completed, release handle 58. Under the restoring force of tension spring 64, intermediate sleeve 56 and lifting frame 52 rise, welding torch 22 leaves the workpiece, and limit frame 67 opens. Pull the welded workpiece out of slide 16. If double-sided welding is required, simply rotate the hanger 180 degrees and reinstall it, repeating step S3.

[0043] Example 2 (Optional Example): In another embodiment, to further improve efficiency, the end of the bidirectional screw 43 can be connected to a graduated adjustment handwheel or a micro motor to achieve rapid digital setting of the spacing. The magnetic sleeve 36 and the movable magnet 62 can also be replaced with pneumatic or electric grippers. The welding torch 22 can be selected from laser welding heads or gas shielded welding torches depending on the material. These variations do not depart from the core concept of this invention to achieve flexible positioning and synchronous welding through an adjustable mechanical mechanism. Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

A magnetic attraction force is generated between the movable magnetic block (62) and the follower block (42) and the adjustment block (35). The magnitude of the magnetic attraction force can be changed by adjusting the distance. Each lifting frame (52) is provided with a limit frame (67). When welding the hanger (13) and the transverse tube (12), the limit frame (67) is stuck on both sides of the transverse tube (12). When the hanger (13) is installed and disassembled, the limit frame (67) does not contact the transverse tube (12).

9. A welding device for processing bathroom accessories according to claim 8, characterized in that: The spot welding mechanism (21) includes a welding gun (22) installed on each of the lifting frames (52), and the joint between the transverse tube (12) and the hanging frame (13) forms a joint seam (23), with the welding guns (22) located at the top of the joint seam (23).

10. A welding method for processing bathroom accessories, employing a welding apparatus for processing bathroom accessories as described in any one of claims 1-9, characterized in that: Includes the following steps: Pre-positioning steps: Based on the size of the workpiece to be welded, pre-adjust the overall positioning mechanism (31) to determine the lateral reference position of the bracket (13), and adjust the double tube positioning mechanism (41) to determine the welding center distance between the two lateral tubes (12); Workpiece loading steps: Insert the hanger (13) into the slide groove (16) of the device and fix it with magnetic attraction; initially place the horizontal tube (12) in the corresponding position of the hanger (13); Linkage positioning and welding steps: Press down the operating handle once to drive the synchronization mechanism (51) so that the two welding guns (22) carriers descend synchronously. During this process, the limiting mechanism (61) first mechanically clamps and magnetically assists in fixing the transverse tube (12) to achieve precise positioning; continue to press down to the working stroke, and the two welding guns (22) simultaneously press against the weld seam and perform spot welding. Reset and unloading steps: Release the handle, the welded parts will automatically reset, and the workpiece can be taken out. Through the simple operation of "one adjustment, one clamping, and one pressing", the complex positioning, clamping and welding actions are integrated into a continuous process, which significantly reduces the difficulty of operation and skill requirements.
