Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a special machine workstation for welding vehicle cylinders. Background Technology

[0002] As a core load-bearing component of various special vehicles (such as tank trucks, chemical transport vehicles, and liquefied gas transport vehicles), the welding quality of the special vehicle cylinder directly affects the vehicle's safety performance and service life. In the manufacturing process of special vehicle cylinders, the welding of straight seams between cylinder components is a critical step. The straightness, penetration, and consistency of the weld seam have a decisive impact on the cylinder's sealing performance, strength, and overall structural integrity. Because special vehicle cylinders typically have large dimensions and long weld seams, specialized welding equipment is required to ensure the stability of the welding process and the uniformity of weld quality.

[0003] In existing special vehicle cylinder welding processes, manual or semi-automatic welding methods are mostly used for splicing and welding cylinder components. A typical operating procedure is as follows: the worker first manually aligns the two cylinder components, holding them in place using clamps or temporary fixing devices, and then operates the welding torch along the predetermined weld seam trajectory. During the welding process, the worker needs to maintain a constant moving speed, welding angle, and torch height while simultaneously observing and adjusting welding parameters in real time to ensure weld quality.

[0004] This traditional welding method has the following technical problems: Key parameters such as moving speed, welding torch height, and welding angle during the welding process are mainly controlled by the experience and skill level of the operators. The instability of manual operation makes it difficult to maintain consistent weld quality. Especially in the welding of long welds, the fatigue of the workers will directly affect the stability of the welding quality, and problems such as uneven welds, uneven penetration, and welding defects are likely to occur.

[0005] Furthermore, due to the large size of the cylindrical components and the long weld seams, manual welding is inefficient, with long completion times for a single weld seam, severely restricting the improvement of production efficiency. At the same time, prolonged manual operation increases the labor intensity and occupational health risks for workers. In addition, existing welding methods lack effective workpiece support and guiding mechanisms, making the cylindrical components prone to displacement or deformation during welding, affecting the geometric accuracy and welding quality of the weld seam. Moreover, the workpiece positioning and welding torch movement systems lack effective synchronous control, making it difficult to achieve precise relative motion control.

[0006] Therefore, how to automate and precisely control the welding process of special vehicle cylinders, improve the consistency and stability of welding quality, and at the same time increase welding efficiency and reduce dependence on the skill level of operators are the technical problems that urgently need to be solved in the current special vehicle cylinder manufacturing field. Utility Model Content

[0007] The technical problem to be solved by this utility model is to address the technical issues of unstable welding quality, low efficiency, and difficulty in precision control in the existing special vehicle cylinder welding process, and to provide a special vehicle cylinder welding workstation that can achieve automated and precise welding, ensure consistent weld quality, and improve welding efficiency.

[0008] The technical solution adopted by this utility model to solve its technical problem is: A dedicated welding machine workstation for vehicle cylinders includes: a first support platform and a second support platform; the first support platform has two parallel slide rails with a rack between them, a sliding platform on the slide rails, and a transmission mechanism on the sliding platform that meshes with the rack to drive the sliding platform to move along the slide rails; the sliding platform also has a column, a fixed arm, a linear module, an electrical box, and a wire feeder, one end of the fixed arm is connected to the column, and the other end is connected to a fixed plate, the linear module is mounted on the fixed plate, the wire feeder is mounted on the sliding platform, and the electrical box is mounted on the sliding platform and connected to the transmission mechanism and the wire feeder; the second support platform has a copper bar and welding torch support mechanism, the welding torch support mechanism is connected to the linear module, the welding torch is mounted on the welding torch support mechanism, the input end of the welding torch is connected to the output end of the wire feeder, and the nozzle of the welding torch is aimed above the copper bar.

[0009] Preferably, the welding torch support mechanism includes a fixed frame, which is a triangular structure, and a pair of bearing fixing seat assemblies are provided on the vertical side, with each bearing fixing seat assembly sleeved on the sliding shaft.

[0010] Preferably, each sliding shaft is connected to guide supports at both ends. The guide supports have an open structure. Multiple guide supports are connected to the moving plate through connectors. The moving plate is fixedly connected to the linear module.

[0011] Preferably, the linear module includes a base and a movable block disposed on the base, the movable block being fixedly connected to the movable plate.

[0012] Preferably, the guide support has a T-shaped opening structure and the connecting parts are rivets.

[0013] Preferably, the bottom surface of the welding torch support mechanism is provided with multiple rolling components, which are located above the copper strip.

[0014] Preferably, the welding torch support mechanism has a built-in lifting mechanism for adjusting the height of the welding torch.

[0015] Preferably, both the first and second support platforms adopt a beam structure, with reinforcing plates on the inner sides of the two wings of the beam structure and adjustable support feet on the bottom surface of the beam structure.

[0016] Preferably, the electrical box is electrically connected to the wire feeder and the transmission mechanism to control the engagement of the transmission mechanism with the rack and pinion, thereby achieving coordinated movement of the sliding platform and the welding torch.

[0017] The beneficial effects of this utility model include the following: By setting parallel slide rails and racks on the first support platform, and cooperating with the sliding platform and transmission mechanism to drive the sliding platform to move in a stable linear motion along the welding direction, the welding torch, wire feeder and electrical box form a linkage control system, which ensures the precise control of the welding torch's movement speed and position. This solves the problems of uneven welds and uneven penetration caused by the welding torch movement relying on human experience and unstable speed and trajectory during traditional manual welding, thus improving the consistency of weld quality and the level of automation in the welding process.

[0018] By setting up a copper bar and welding torch support mechanism on the second support platform, and cooperating with the linear module to achieve precise guidance and height adjustment of the welding torch, a stable workpiece support and welding torch guiding system is formed. This avoids displacement or deformation of the cylindrical parts due to lack of support during the welding process, while ensuring that the welding torch always maintains a reasonable height and angle. This solves the technical problem of difficult welding accuracy control and significantly improves the geometric accuracy and welding stability of the weld. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but these specific embodiments do not limit the scope of protection of the present invention in any way. Example

[0022] like Figure 1-3 As shown, a dedicated welding workstation for vehicle cylinders includes a first support platform 1 and a second support platform 2, which are arranged parallel to each other and each supports different functional components. The first support platform 1 mainly supports the movement system and welding control components, while the second support platform 2 mainly supports the workpiece to be welded (i.e., the dedicated vehicle cylinder component 15) and the welding execution components. This workstation is mainly used for automated linear welding of the dedicated vehicle cylinder component 15, enabling precise control and efficient operation of the welding process, and solving the problems of unstable welding quality and low efficiency in traditional manual welding.

[0023] Specifically, the first support platform 1 adopts a beam-type main structure, arranged in a long strip shape. Multiple reinforcing plates 3 are provided on the inner sides of both wings of the beam structure. These reinforcing plates 3 are vertically welded to the inner sides of the wing plates and evenly distributed along the length direction to enhance overall rigidity and resistance to deformation, ensuring the stability of the platform structure during long-distance welding. The bottom surface of the beam structure is equipped with multiple height-adjustable support feet 4, each using a threaded adjustment mechanism for precise adjustment of the platform's height and level.

[0024] The first support platform 1 is provided with two parallel slide rails 5, which extend along the length of the platform. A rack 6 is provided between the two slide rails 5, which meshes with the gear of the transmission mechanism 8 to drive the sliding platform 7 to move along the slide rails 5.

[0025] The sliding platform 7 is slidably mounted on the slide rail 5, and a guide structure is provided at the bottom, which is also mounted on the slide rail 5. The sliding platform 7 is equipped with a transmission mechanism 8, which includes a drive motor and a gear assembly. The drive motor is connected to the gear assembly through a gear reducer. When the motor is running, the gear assembly meshes with the rack 6, driving the sliding platform 7 to move linearly at a constant speed along the slide rail 5.

[0026] A column 9 is vertically welded onto the sliding platform 7. A fixed arm 10 is connected to the column 9. One end of the fixed arm 10 is connected to the column 9, and the other end extends forward and is connected to a fixed plate. The fixed plate is vertically positioned to provide a mounting base for the linear module 11. The linear module 11 is mounted on the fixed plate and includes a base 111 and a movable block 112 disposed on the base 111. The movable block 112 is capable of making precise linear movements on the base 111.

[0027] The sliding platform 7 is also equipped with an electrical control box 12 and a wire feeder 13. The electrical control box 12 serves as the control center and is electrically connected to the transmission mechanism 8 and the wire feeder 13 to achieve unified control of the motion system and the welding wire supply system. The wire feeder 13 is installed on the sliding platform 7, and its output end is connected to the input end of the welding torch 17 through a flexible hose to provide a stable supply of welding wire for the welding process.

[0028] The second support platform 2 also adopts a beam structure with an internal reinforcing plate 3 and adjustable support feet 4 at the bottom for support and leveling. The top surface of the second support platform 2 is provided with a copper strip 14 along its length. The copper strip 14 serves as a conductive reference surface during the welding process. Two special vehicle cylinder components 15 are fitted in a "[]" shape on the beam structure of the second support platform 2, and their joints are placed on the copper strip 14, i.e., the conductive reference surface.

[0029] A welding torch support mechanism 16 is provided above the copper strip 14. The welding torch support mechanism 16 includes a fixed frame 161, a sliding shaft 162, a guide support 163, and a moving plate 164. The fixed frame 161 adopts a triangular truss structure, and a pair of bearing fixing seat assemblies 165 are provided on the vertical side. Each bearing fixing seat assembly 165 contains a linear bearing, which is sleeved on the sliding shaft 162 and can move linearly. The two ends of the sliding shaft 162 are respectively connected to the guide support 163. The guide support 163 has a T-shaped opening structure. Multiple guide supports 163 are fixedly connected to the moving plate 164 by rivets, thereby forming an integral moving platform. The moving plate 164 is fixedly connected to the moving block 112 of the linear module 11, so that the movement of the linear module 11 can be accurately transmitted to the welding torch assembly, realizing the precise adjustment of the welding torch 17.

[0030] The welding torch 17 is mounted on the welding torch support mechanism 16. The support mechanism has a built-in lifting mechanism 171, which can adjust the height of the welding torch 17 to meet the welding needs of cylindrical components of different specifications. The nozzle of the welding torch 17 is aligned with the top of the copper strip 14, maintaining a reasonable distance and angle with the workpiece joint to ensure welding quality.

[0031] The bottom surface of the welding torch support mechanism 16 is provided with multiple rolling parts 18. The rolling parts 18 are located above the copper strip 14 and press against the surface of the special vehicle cylinder part 15 and roll synchronously during the welding process to ensure welding accuracy.

[0032] When using the above workstation, the operator first adjusts the level and relative position of the first support platform 1 and the second support platform 2 using the support feet 4, ensuring that the slide rail 5 and the copper strip 14 are parallel and aligned. Then, the two special carriage body components 15 are fitted onto the two wings of the beam structure of the second support platform 2 in a "[]" shape, with the butt joint positioned at the center of the copper strip 14. The operator adjusts the position of the welding torch 17 using the lifting mechanism 171 and the linear module 11 to accurately align it with the weld seam, and sets process parameters such as welding current, voltage, and moving speed in the electrical box 12.

[0033] After the system is started, the transmission mechanism 8 drives the sliding platform 7 to move along the slide rail 5, which in turn drives the welding torch 17 to move along the weld direction at a constant speed. At the same time, the wire feeder 13 continuously feeds wire to the welding torch 17, and the electrical box 12 controls the welding torch 17 to generate a stable electric arc to achieve welding. After the welding is completed, the system stops automatically, and the workpiece can be removed after cooling.

[0034] The combination of rack and pinion drive 6 and linear module 11 for precise positioning ensures the straightness and speed stability of the welding torch 17, solving problems such as uneven speed and non-straight welds in manual welding. The centralized control of electrical box 12 ensures stable and consistent welding parameters, reducing reliance on manual skills. The lifting mechanism 171 of welding torch support mechanism 16 and the support of rolling component 18 effectively solve the problems of welding support and welding quality control for large-sized workpieces.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any innovative improvements or substitutions based on the present invention should fall within the scope of the claims of the present invention. Furthermore, the parameters, materials, and processes mentioned in the above embodiments are not unique. Without departing from the technical essence of the present invention, those skilled in the art can make various alternative choices, and these alternative solutions should also be considered to fall within the scope of protection of the present invention.
