Description

Technical Field

[0001] The utility model relates to the technical field of welding positioning tooling, in particular to a welding positioning tooling for a lower beam of a passenger elevator car. Background Art

[0002] The lower beam of the car is a key component supporting the car structure. It not only needs to bear the weight of the car itself, but also the weight of the passengers and dynamic loads. Therefore, the structural strength and connection quality of the lower beam are directly related to the safety and stability of the entire car.

[0003] In the car structure, the manufacture and assembly of the lower beam is a technical challenge, especially the connection between the lower beam body and the side panels and angle panels. Specifically, the welding of the lower beam of the passenger elevator car is more complicated, and the two side panels need to be welded to the two ends of the lower beam body, and the four angle panels need to be welded between the two sides of the side panels and the ends of the lower beam body.

[0004] Traditional manual welding methods face multiple challenges in this process. First, positioning is difficult and requires extremely high technical skills from workers. The precise positioning of the side panels and angle panels with the lower beam body not only requires the welding workers to have rich experience, but also requires delicate operations and adjustments during the welding process. This method, which is highly dependent on the skills of the operators, leads to uncertainty in the welding results, thus affecting the welding accuracy and product consistency.

[0005] Secondly, in traditional welding methods, workers need to move between different positions to complete welding work, and sometimes even need to drill into the narrow bottom of the lower beam to operate. This working environment not only puts a huge physical burden on workers, but also may affect the accuracy and efficiency of welding. Especially when multiple workers are required to operate at the same time, collaborative work increases the complexity of the operation and also increases safety risks.

[0006] More importantly, welding accuracy is difficult to guarantee. In the complex welding process, due to the influence of human factors, such as the instability of manual welding, operator fatigue, and changes in environmental conditions, the welding quality may fluctuate. Such fluctuations not only affect the overall quality of the car, but may also cause long-term hidden dangers to the safety of the elevator.

[0007] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present invention is made based on this situation. Utility Model Content

[0008] The utility model aims to overcome the deficiencies of the prior art and provide a welding positioning tool for a lower beam of a passenger elevator car which has a simple structure, is convenient to operate and can accurately position.

[0009] The utility model is realized by the following technical solutions:

[0010] In order to solve the above technical problems, the utility model provides a welding positioning tool for the lower beam of a passenger elevator car, which is used to assist in welding together the lower beam body, the vertical side panels located at both ends of the lower beam body, and the angle panels located between the two side edges of the side panels and the corresponding ends of the lower beam body, comprising a vertical main support plate, a baffle plate perpendicular to the main support plate is provided in the middle of the inner side surface of the main support plate, and wing plates perpendicular to the main support plate and extending outward are provided on both sides of the outer side surface of the main support plate, and a plurality of positioning holes corresponding to the original hole positions on the angle plates are opened on the wing plates;

[0011] The main support plate is close to the side plate, the baffle is close to the upper surface of the lower beam body, the wing plate is close to one side of the angle plate, and a detachable fastener is provided between the positioning hole and the corresponding hole position on the angle plate to fix the two.

[0012] In order to further solve the technical problem to be solved by the utility model, in a welding positioning tooling for the lower beam of a passenger elevator car provided by the utility model, the baffle is provided with avoidance openings on both sides of the connection between the baffle and the main support plate, for providing avoidance space for the welding between the other side of the angle plate and the end of the lower beam body.

[0013] In order to further solve the technical problem to be solved by the utility model, in a welding positioning tool for a lower beam of a passenger elevator car provided by the utility model, a reinforcing rib is provided between the upper surface of the baffle and the inner side surface of the main support plate.

[0014] In order to further solve the technical problem to be solved by the utility model, in a welding positioning tool for a lower beam of a passenger elevator car provided by the utility model, the two wing plates and the main support plate are formed in one piece.

[0015] In order to further solve the technical problem to be solved by the utility model, the utility model provides a welding positioning tool for a lower beam of a passenger elevator car, wherein the fasteners include bolts and nuts.

[0016] In order to further solve the technical problem to be solved by the utility model, in a welding positioning tool for a lower beam of a passenger elevator car provided by the utility model, a hand-carrying hole is opened on the main supporting plate.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] 1. The welding positioning tooling has a relatively simple structure, is easy to manufacture, and has a relatively low cost.

[0019] 2. In actual welding operations, the use of this tool is also very simple. First, make the main support plate close to the side plate, and make the baffle close to the upper surface of the lower beam body, so that the position of the lower beam body can be stabilized. Next, make the wing plate close to one side of the angle plate, and fix the wing plate and the angle plate with fasteners, so as to complete the positioning of the entire welding structure. This positioning ensures the accurate alignment of the lower beam body, side plate and angle plate during the welding process, and also ensures the verticality and stability between them, so that high-precision welding can be carried out, and they will not deform during the welding process. Through the application of this welding positioning tool, not only can the efficiency and accuracy of the welding process be significantly improved, but also the welding defects caused by improper positioning can be reduced, thereby improving the overall quality and safety performance of the lower beam of the passenger elevator car.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figures 1 to 3 As shown, an innovative passenger elevator car lower beam welding positioning tool is introduced, which is used to assist in welding the lower beam body 101, the vertical side panels 102 at both ends of the lower beam body 101, and the angle panels 103 located between the two sides of the side panels 102 and the corresponding ends of the lower beam body 101, aiming to solve the problems of difficult positioning and difficult to ensure welding accuracy in traditional welding methods. The design of this tool fully considers the high requirements for accuracy and stability in the welding process, and through the sophisticated structural design, it realizes the rapid and accurate positioning of the welding parts, greatly improving the welding efficiency and quality.

[0026] The welding positioning tool is mainly composed of a vertical main support plate 1, and a baffle 2 perpendicular to it is provided in the middle of its inner side surface for positioning the position of the lower beam body 101.

[0027] The wing plates 11 extending perpendicularly and outwardly are arranged on both sides of the outer side of the main support plate 1. The wing plates 11 are provided with a plurality of positioning holes 111, which correspond to the pre-set holes on the angle plate 103. In order to fix and connect these components, a detachable fastener 3 is arranged between the positioning holes 111 and the corresponding holes on the angle plate 103. Through this design, the angle plate 103 and the wing plates 11 are precisely connected.

[0028] The welding positioning tooling has a relatively simple structure, is easy to manufacture and has a relatively low cost.

[0029] In actual welding operation, the use of the tool is also very simple. First, the main support plate 1 is closely attached to the side plate 102, and the baffle plate 2 is closely attached to the upper surface of the lower beam body 101, so that the position of the lower beam body can be stabilized. Then, the wing plate 11 is closely attached to one side of the angle plate 103, and the wing plate 11 and the angle plate 103 are fixed by the fastener 3, so that the positioning of the entire welding structure is completed.

[0030] This positioning ensures accurate alignment of the lower beam body 101, the side plates 102 and the angle plates 103 during the welding process, while also ensuring verticality and stability therebetween, thereby enabling high-precision welding without deformation of the lower beam body 101, the side plates 102 and the angle plates 103 during the welding process.

[0031] Through the application of this welding positioning tooling, not only can the efficiency and accuracy of the welding process be significantly improved, but also the welding defects caused by improper positioning can be reduced, thereby improving the overall quality and safety performance of the lower beam of the passenger elevator car.

[0032] Preferably, in order to improve the convenience of assembly and disassembly and ensure the firmness of the structure, the selected fastener 3 is a pair of bolts and nuts. The combination of bolts and nuts is a common fixing method in mechanical design, which can provide a reliable and reusable connection method.

[0033] More specifically, the baffle plate 2 is provided with avoidance openings 21 on both sides of the connection between the baffle plate 2 and the main support plate 1, which are used to provide avoidance space for welding between the other side of the angle plate 103 and the end of the lower beam body 101. Specifically, the design of the avoidance opening 21 takes into account that during the welding process, not only the lower beam body 101 and the angle plate 103 need to be fixed and positioned, but also the convenience of the welding operation needs to be taken into account. In actual welding operations, for the welding point between the end of the lower beam body 101 and the other side of the angle plate 103, sufficient operating space is required to ensure that the welding gun can smoothly enter the welding position and perform high-quality welding work. The avoidance opening 21 just provides the necessary space for this operation, allowing the welding gun to more easily contact the welding part, thereby effectively improving the welding efficiency and welding quality.

[0034] In addition, the presence of the avoidance opening 21 also means that the baffle 2 provides convenience for the welding operation without reducing the overall efficiency of the tooling due to obstruction of the welding operation. This design takes into account both the stable support for the welding structure and the actual needs of the welding operation.

[0035] The avoidance opening 21 has an additional benefit in that it provides a certain discharge path for the heat and welding spatter that may be generated during the welding process, which helps to keep the working area clean and also reduces the negative impact that the heat accumulation generated by welding may have on the tooling material. This consideration not only improves the safety of welding, but also extends the service life of the tooling.

[0036] In order to further improve the structural strength of the positioning tool, a reinforcing rib 4 is provided between the upper surface of the baffle 2 and the inner side of the main support plate 1. This design effectively increases the overall rigidity, ensuring that the tool can stably support the assembly during the welding process, thereby ensuring the welding accuracy and quality.

[0037] Specifically, the reinforcing ribs 4 are fixed between the upper surface of the baffle 2 and the inner side of the main support plate 1 by welding. This welding and fixing method enables the reinforcing ribs 4 to form a whole with the baffle 2 and the main support plate 1, effectively dispersing and transmitting the forces acting on the tooling, especially providing additional support and stability when bearing loads in various directions. The presence of the reinforcing ribs 4 significantly improves the bending and torsion resistance of the tooling, making it less likely to deform when dealing with heavier components or bearing greater welding forces, thereby ensuring the accuracy of the welding operation.

[0038] In addition, the reinforcing ribs 4 also help to improve the durability and service life of the entire tooling. The high temperature and vibration generated during the welding process may cause fatigue to the tooling, which may affect its structural integrity in the long run. The reinforcing ribs 4 can reduce the wear caused by long-term use or repeated loads by improving the stability of the structure, and slow down the process of material fatigue.

[0039] More specifically, in order to achieve efficient production and simplify the assembly process, the two wing panels 11 and the main support panel 1 are integrally formed. That is, the overall shape of the main support panel 1 is like a half-mouth. The half-mouth structure provides good spatial support capacity and structural strength. The advantage of integral molding is that it reduces welding and splicing parts, which not only reduces potential stress concentration points, but also improves the stability and durability of the overall structure.

[0040] In addition, common channel steel can be used to make such a structure. Using the standard size and shape of the channel steel, a half-mouth-shaped main support plate that meets the design requirements can be quickly manufactured through cutting and forming. This manufacturing process is much simpler than complex combination or welding processes, while also ensuring high strength and stable quality.

[0041] More specifically, a hand hole 12 is provided on the main support plate 1 to facilitate carrying the welding tool. The provision of the hand hole makes it easier and safer to carry and operate the entire welding tool, further improving work efficiency and comfort.

[0042] In practical applications, the presence of the hand-carrying hole 12 greatly improves the portability of the welding tool, allowing workers to more conveniently move from one workstation to another, or quickly deploy between different working environments. This design detail not only saves time and reduces work intensity, but also improves the overall safety of the workplace.
