Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary tooling, specifically to an auxiliary device for improving the stability of the welding process. Background Technology

[0002] Currently, in the welding manufacturing process and welding training of locomotives and rolling stock, it is sometimes necessary to perform overhead welding on a certain position under the vehicle. However, the welding operation space in this position is sometimes relatively open, with no protruding objects on the welding surface within the space accessible to the arms. Therefore, the welding operation relies entirely on the operator's arm strength to control the lifting and swinging of the welding torch. Because the arms are suspended without support, several problems can easily arise. For example, the operator's time for stable lifting of the welding torch with suspended arms is much shorter than in other positions, resulting in more frequent pauses for the same weld length and an increase in the number of welded joints. Overhead welding positions can easily cause premature fatigue in the operator's arms, leading to instability in the welding process, resulting in decreased welding quality and welding defects such as excessive straightness and poor appearance, thus affecting the overall welding quality.

[0003] In current technologies, to improve welding quality and operator comfort, a protruding plate is usually welded to the welding area. During welding, the operator supports the arm holding the welding gun to increase stability and comfort. However, this method lacks flexibility, and additional welding quality problems can easily arise when the plate is fixed in place. Utility Model Content

[0004] To address the aforementioned problems, this invention provides an auxiliary device for improving the stability of the welding process. This device offers high flexibility, avoids generating additional welding quality issues, and reduces the operational difficulty and fatigue for welding operators, thereby enhancing the stability of the welding process and improving welding quality. To achieve the above objectives, the technical solution adopted by this utility model is as follows: An auxiliary device for improving the stability of the welding process includes a lead screw, a first sleeve, a second sleeve, a connecting rod, a slotted support rod, fasteners, and a sliding rod. Each end of the lead screw is threaded to a first sleeve, and the other end of each of the two first sleeves is connected to a fastener; a second sleeve is fitted on each first sleeve; the second sleeve can move and rotate relative to the first sleeve, each of the two second sleeves is connected to a connecting rod, and the other end of each of the two connecting rods is fixedly connected to a sliding rod, and the two sliding rods are slidably connected to the slotted support rod.

[0005] As a further technical solution, the connecting rod is a telescopic connecting rod.

[0006] As a further technical solution, the fastener is a suction fastener.

[0007] As a further technical solution, the fastener is a suction cup, which is adsorbed together with the first sleeve.

[0008] As a further technical solution, the fastener is a top-tightening fastener.

[0009] As a further technical solution, the top fastener is a top fastening plate, and the top fastener is detachably connected to the end of the first sleeve by screws or bolts.

[0010] As a further technical solution, the fastener is a clamping fastener.

[0011] As a further technical solution, the clamping fastener is a clamp, which is detachably connected to the end of the first sleeve by screws or bolts.

[0012] As a further technical solution, a fixed rotating handle is provided on the lead screw.

[0013] As a further technical solution, the two ends of the slotted support rod are grooved with the same diameter as the sliding rod and penetrating the sleeve wall thickness, while the middle part of the slotted support rod is not slotted.

[0014] The beneficial effects of this utility model are as follows: This invention offers good flexibility, allowing for easy installation and disassembly. During use, the entire device is fixed to both sides of the operator's arms via a lead screw, a first sleeve, and fasteners. The operator's arms are then supported by a slotted support rod, solving the problem of premature fatigue of the welding operator's arms and unstable welding process leading to decreased welding quality during welding in the overhead welding position where there is no support. After welding is completed, the entire device can be disassembled by rotating the lead screw.

[0015] Furthermore, the angle of the slotted support rod can be adjusted by adjusting the second sleeve, and the height of the slotted support rod can be adjusted by adjusting the connecting rod, thus making the auxiliary device adaptable to more welding operators.

[0016] Furthermore, this utility model utilizes three fixing methods—clamping, suction, and push-to-lock—to adapt to different overhead welding space scenarios. The adjustable arm rest allows the operator's lifting arm to rest in a comfortable position, significantly reducing operator fatigue during welding and improving the stability and quality of the welding process.

[0019] As described in the background section, in existing welding production sites and training, there are numerous overhead welding positions. When there are no other supports around the overhead welding position, the welding operator can only rely on the strength of their suspended arms to perform the welding action, resulting in operator fatigue, poor welding action stability, short action duration, and low welding quality. To solve the above technical problems, this utility model proposes an auxiliary device to improve the stability of the welding process. This solution allows for support on one side of the operator's lifting arm, increasing stability and reducing operator fatigue, thereby achieving the goal of stable welding and improved welding quality. Furthermore, by changing the fixing devices at both ends of this device, it can be adapted to different welding scenarios and can be widely used in on-site welding operations and welding training.

[0020] In a typical embodiment of this utility model, such as Figure 1As shown, an auxiliary device for improving the stability of the welding process is disclosed. This device is divided into two main working parts. The first part is the fixing part of the auxiliary device, which consists of a lead screw 1, a first sleeve 2, a pre-tightening fastener 7, a clamping fastener 8, and a suction fastener 9. The second part is the arm support space, which consists of a second sleeve 3, a connecting rod 4, a slotted support rod 5, a sliding rod 6, etc. During the welding process, the operator's arm is generally supported on the slotted support rod 5. In some scenarios, it can also be supported on the lead screw 1 and the first sleeve 2.

[0021] Specifically, the auxiliary device for improving welding process stability provided in this embodiment includes a lead screw 1, a first sleeve 2, a second sleeve 3, a connecting rod 4, a slotted support rod 5, fasteners, and a sliding rod 6; each end of the lead screw 1 is threadedly connected to a first sleeve 2, and the other end of each of the two first sleeves 2 is connected to a fastener; a second sleeve 3 is fitted onto each first sleeve 2; the second sleeve 3 can move and rotate relative to the first sleeve 2, and each of the two second sleeves 3 is connected to a connecting rod 4, the other end of each of the two connecting rods 4 being fixedly connected to a sliding rod 6. The two sliding rods 6 are slidably connected to the slotted support rod 5. The auxiliary device proposed in this embodiment has good flexibility, allowing for easy installation and removal. During use, the entire device is fixed to both sides of the operator's arms via the lead screw 1, the first sleeve 2, and fasteners. The slotted support rod then supports the operator's arms, solving the problem of premature fatigue of the welding operator's arms and unstable welding process leading to decreased welding quality during welding in the overhead welding position where there is no support. After welding, the entire device can be removed by rotating the lead screw. Furthermore, the angle of the slotted support rod can be adjusted by adjusting the second sleeve 3, and the height of the slotted support rod can be adjusted by adjusting the connecting rod 4, thus allowing the auxiliary device to accommodate more welding operators.

[0022] More specifically, both ends of the aforementioned lead screw 1 are threaded, forming a double-threaded structure, and there is a fixed handle 10 in the middle of the lead screw. Both ends of the lead screw 1 are placed inside the first sleeve 2 and threadedly connected to the first sleeve 2. Multiple fixed handles 10 are provided for rotating the lead screw. There are two first sleeves 2. The inner end of each sleeve has an internal thread. The two first sleeves 2 are threaded to both ends of the lead screw 1. The outer end is a movable contact part. The suction fastener 7, the top fastener 8, or the clamping fastener 9 can be replaced according to the working scenario. When the first sleeve 2 is engaged with the lead screw 1, rotating the lead screw 1 can make the first sleeves 2 at both ends extend and retract.

[0023] The second sleeve 3 includes two sleeves, which are respectively fitted onto the two first sleeves 2 and can rotate and move relative to the first sleeves 2. The first sleeves 2 have fastening bolts that can fasten the second sleeve 3 to the first sleeves 2. The second sleeve 3 has a connecting rod 4 that is fixedly connected.

[0024] The connecting rod 4 includes two rods, each of which is a telescopic rod that can extend and retract vertically. The top of the rod is fixedly connected to the second sleeve 3, and the bottom is connected to the sliding rod 6. The sliding rod 6 can slide along the slotted support rod 5. The slotted support rod 5 has a groove with the same diameter as the sliding rod 6 that penetrates the sleeve wall thickness. The middle part is not slotted. The groove allows the sliding rod 6 to slide inside.

[0025] The sliding rod 6 is fixedly connected to the connecting rod 4 and placed inside the slotted support rod 5, and can move with the extension and retraction of the connecting rod 4.

[0026] In the above-mentioned device, after the two first sleeves 2 and fasteners are fixed at a certain height by the lead screw, the tilt angle of the slotted support rod 5 can be adjusted by rotating the second sleeve 3, and the height of the slotted support rod 5 can be adjusted by the telescopic connecting rod 4.

[0027] Furthermore, the aforementioned suction fastener 7, top fastener 8, and clamping fastener 9 are fastening contact parts. Depending on the scenario, the top fastener can be selected. Specifically, suction fastener 7 is a suction cup; top fastener 8 is a top fastening plate; and clamping fastener 9 is a clamp.

[0028] The suction fastener 7 is suction-connected to the end of the first sleeve 2; the top fastener 8 is detachably connected to the end of the first sleeve 2 by screws or bolts; and the clamping fastener 9 is also detachably connected to the end of the first sleeve 2 by screws or bolts.

[0029] The above-mentioned device can be used in two ways, as follows: The aforementioned auxiliary devices can be used individually or in pairs; when used individually, the auxiliary device is located on the outside of one of the arms; when used in pairs, the auxiliary devices are located on the outside of both arms. When there are other supporting devices on the front and rear sides of the weld to be welded, the fixed handle 10 can be rotated first to move the two first sleeves 2 forward and backward. When they are moved to the appropriate position, they are connected to the supporting devices on the front and rear sides by the suction fastener 7, the top fastener 8, or the clamping fastener 9 to fix the entire auxiliary device. Then, according to the length of the operator's arm and the comfort of operation, the connecting rod 4 and the second sleeve 3 are adjusted. When the slotted support rod 5 is lowered or raised to the appropriate height, the fixed connecting rod 4 is then fixed to prevent it from rising or falling further. Then, the angle of the connecting rod 4 relative to the lead screw 1 and the first sleeve 2 can be adjusted by rotating the second sleeve 3, thereby realizing the angle adjustment of the slotted support rod 5. At this time, the slotted support rod 5 forms a height and angle that is conducive to stable, comfortable and flexible operation, and welding can begin.

[0030] When in use, if there are no other supporting devices on the front and back sides of the weld to be welded, the slotted support rod 5 can be fixed to the ground or other supporting base plate. Then, the height of the auxiliary device can be adjusted by the lifting linkage 4. When it is raised to a suitable height, the linkage can be fixed to prevent it from rising or falling further. At this time, the lead screw 1 and the first sleeve 2 can replace the slotted support rod 5 to support the arm, and then welding can begin.

[0031] It should be noted that this device is mainly used in scenarios where there are other supporting devices on the front and back sides of the weld.

[0032] Furthermore, in this embodiment, different fasteners can be selected according to the structure of the front and rear support devices. For scenarios suitable for adsorption, the adsorption fastener 7 is selected; for scenarios suitable for top tightening, the top tightening fastener 8 is selected; and for scenarios suitable for clamping, the clamping fastener 9 is selected.

[0033] This invention achieves greater stability in the welding process by providing arm support and fixation, thereby reducing operator fatigue and improving welding quality. It primarily addresses the problem of premature arm fatigue and welding instability leading to decreased welding quality in overhead welding positions where there is no support. This invention utilizes three fixing methods—clamping, supporting, and suction—to adapt to different overhead welding spaces. Furthermore, the adjustable arm support position places the operator's arm in a comfortable position, significantly reducing operator fatigue and improving welding stability and quality.

[0034] Finally, it should be noted that relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
