TECHNICAL FIELD

[0001] The utility model relates to the field of welding positioning fixture, concretely to a quick positioning device for excavator welding piece welding. BACKGROUND

[0002] The quick positioning device for excavator welding piece welding is a series of devices designed to improve the efficiency and precision of welding operations, including positioning devices for specific application scenarios such as pipeline welding. These devices integrate advanced fixtures, positioning, and clamping devices to achieve quick and precise fixation and positioning of excavator welding pieces, especially pipeline parts. They not only improve the stability and consistency during welding, but also significantly enhance the welding quality and production efficiency.

[0003] The present inventors have found the following problems in practical use:

[0004] The existing quick positioning device for excavator welding piece welding, including the pipeline welding positioning device, can accurately butt and fix two pipes. However, the spacing between the two pipes during welding is usually determined by the visual judgment of the operator, which reduces the precision of pipeline welding and may affect the welding effect, thereby reducing the convenience of use of the quick positioning device for excavator welding piece welding.

[0005] Therefore, it is necessary to provide a quick positioning device for excavator welding piece welding to solve the above technical problems. SUMMARY

[0006] The technical problem to be solved by the utility model is that the spacing between the two pipes is usually determined by the visual judgment of the operator, which reduces the precision of pipeline welding. To overcome the above defects of the prior art, a quick positioning device for excavator welding piece welding is provided.

[0007] To achieve the above purpose, the technical scheme of the utility model is as follows: a quick positioning device for excavator welding piece welding, comprising a device main body, a clamping structure is arranged below the device main body, a pressing piece is arranged on one side of the clamping structure, a limiting groove is formed on the surface of the pressing piece, the pressing piece and the clamping structure are connected through a fastening bolt, a hand wheel is arranged on one side of the fastening bolt, a positioning bolt is arranged on one side of the pressing piece, the pressing piece is in a whole arc structure, and after rotation, it abuts against the clamped pipe.

[0008] By adopting the technical scheme, the second bolt is rotated by rotating the handle, and the distance between the device body and the movable mechanism can be flexibly adjusted. With the change of the distance, the movable block slides in the movable groove. Due to the inclined arrangement of the movable groove, the clamping structure can be self-adaptively adjusted according to the actual size of the pipeline, so as to ensure the stable and accurate clamping of the first pipeline. After the clamping of the first pipeline is completed, the handle is easily separated from the pressing piece by rotating the handle. Then, under the limiting action of the positioning bolt, the pressing piece is rotated to the position adjacent to the first pipeline. Then, the second pipeline is placed on the other side of the device body and is in close contact with the pressing piece. In order to further fix the position of the second pipeline, the first screw on the limiting rod is rotated to make one end of the first screw abut against the second pipeline.

[0009] Further, the pressing piece, the limiting groove, the positioning bolt and the fastening screw are provided with two groups and are mirror arranged.

[0010] By adopting the above technical scheme, the device can produce more balanced clamping force when clamping the pipeline, effectively preventing the pipeline from deviating or deforming due to uneven force during welding.

[0011] Further, the second screw is provided inside the device body, the movable mechanism is provided below the device body, and the bottom of the second screw is threadedly connected with the movable mechanism.

[0012] By adopting the above technical scheme, the second screw can become a key component for adjusting the distance between the device body and the movable mechanism. By rotating the handle to drive the second screw, the relative position between the device body and the movable mechanism can be easily adjusted, and the clamping structure can be accurately adjusted to adapt to pipelines of different sizes.

[0013] Further, the movable mechanism is provided with movable blocks on both sides, the clamping structure is provided with movable grooves on both sides, and the movable blocks are slidably connected in the movable grooves.

[0014] By adopting the above technical scheme, when the movable mechanism is driven by the second screw, the force can be uniformly transmitted to the clamping structure through the movable blocks, so as to accurately adjust the clamping structure.

[0015] Further, a group of limiting rods are provided below the movable mechanism, two groups of limiting rods are provided on the clamping structure, and the three groups of limiting rods are arranged in a circular array and are adapted to the clamped pipeline.

[0016] By adopting the above technical scheme, it is ensured that the movable mechanism will not deviate or shake excessively when adjusting and clamping the pipeline.

[0017] Furthermore, the limiting rod is internally threaded with a first bolt, and one end of the first bolt abuts against the pipe.

[0018] By adopting the above technical solution, the first bolt can be firmly connected inside the limiting rod and will not easily loosen or fall off due to external force.

[0019] Furthermore, a handle is provided through the top of the second bolt, which provides a gripping point for the operator.

[0020] By adopting the above technical solution, the handle becomes the direct contact point between the operator and the main body of the device, providing the operator with a stable and comfortable gripping point.

[0021] Compared with related technologies, the rapid positioning device for welding excavation and drilling components provided by this utility model has the following beneficial effects:

[0022] This utility model provides a rapid positioning device for welding excavated and drilled components. Through a pressure plate and a positioning bolt, the positioning device rotates a second bolt by turning a lever, making the distance between the main body of the device and the movable mechanism adjustable. Furthermore, the sliding of the movable block within the movable groove allows the clamping structure to adaptively adjust according to the pipe size, ensuring a stable clamping of the first pipe. Simultaneously, turning the handwheel separates the fastening bolt from the pressure plate and rotates the pressure plate to one side of the first pipe, providing a precise positioning point for the second pipe. Then, turning the first bolt on the limiting rod brings it into contact with the second pipe, ensuring a precise distance between the two pipes. The presence of the pressure plate avoids the problem of relying on manual visual estimation for pipe spacing in traditional welding, improving the accuracy and effectiveness of pipe welding. It also enhances the ease of use of the positioning device, reduces operational difficulty, and increases work efficiency. Attached Figure Description

DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of the utility model, the utility model will be described more fully below with reference to the relevant drawings. The drawings show the typical embodiments of the utility model.

[0029] As Figure 1 shown, a kind of excavator welding part welding quick positioning device of the utility model, as Figures 1-4 shown, including device main body 1, the lower portion of device main body 1 is provided with clamping structure 4, one side of clamping structure 4 is provided with pressing piece 10, limiting groove 11 is opened on the surface of pressing piece 10, pressing piece 10, clamping structure 4 are connected by fastening bolt 13, one side of fastening bolt 13 is provided with hand wheel 14, one side of pressing piece 10 is provided with positioning bolt 12, pressing piece 10 is overall arc-shaped structure, and after rotating, it is abutted with the pipe clamped, by operating handle 2 and rotating second bolt 9, the spacing between device main body 1 and movable mechanism 3 can be flexibly adjusted by this action, with the change of spacing, movable block 6 slides in movable slot 5, since movable slot 5 is inclinedly arranged, clamping structure 4 can be self-adaptively adjusted according to the actual size of pipe, to ensure the stable and accurate clamping of first pipe, while clamping first pipe is completed, by screwing hand wheel 14, fastening bolt 13 can be easily separated from pressing piece 10, then, under the limiting action of positioning bolt 12, pressing piece 10 is actuated and rotated to the position adjacent to first pipe, then, second pipe is placed on the other side of device main body 1, and it is ensured that it is closely abutted with pressing piece 10, in order to further fix the position of second pipe, first bolt 8 on limiting rod 7 is screwed respectively, so that the end of first bolt 8 is abutted with second pipe, since pressing piece 10 is ingeniously arranged, the device effectively avoids the problem that pipe spacing needs to rely on operator visual judgment in traditional welding process, this improvement not only significantly improves the precision and overall effect of pipe welding, but also greatly improves the use convenience of excavator welding part welding quick positioning device, reduces operation difficulty, so that the whole welding process is more efficient and smooth.

[0030] As Figure 2 , Figure 3 , Figure 4As shown, two sets of abutting pieces 10, limiting grooves 11, positioning pegs 12 and fastening bolts 13 are provided and arranged in mirror image, so that the device can generate more balanced clamping force when clamping the pipeline, effectively preventing the pipeline from shifting or deforming due to uneven stress during welding. At the same time, the mirror image arrangement of the two sets of abutting pieces 10 provides two precise abutting points for the second pipeline, further improving the alignment accuracy during pipeline welding. The cooperation of the two sets of limiting grooves 11 and positioning pegs 12 ensures the stability and accuracy of the abutting pieces 10 during rotation and abutting. In addition, the two sets of fastening bolts 13 not only enhance the connection strength between the clamping structure 4 and the abutting pieces 10, but also enable the operator to operate more flexibly and conveniently when adjusting the clamping force and abutting position.

[0031] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , a second bolt 9 is provided inside the device body 1, and an activity mechanism 3 is provided below the device body 1. The bottom of the second bolt 9 is threadedly connected with the activity mechanism 3, so that the second bolt 9 can become a key component for adjusting the distance between the device body 1 and the activity mechanism 3. By turning the handle 2 to drive the second bolt 9 to rotate, the relative position between the device body 1 and the activity mechanism 3 can be easily adjusted, thereby realizing accurate adjustment of the clamping structure 4 to adapt to pipelines of different sizes. At the same time, the activity mechanism 3 is provided below the device body 1, and the bottom of the second bolt 9 is threadedly connected with the activity mechanism 3. This connection not only ensures the firm connection between the second bolt 9 and the activity mechanism 3, but also enables the activity mechanism 3 to move stably and smoothly below the device body 1 when driven by the second bolt 9. This not only improves the stability and reliability of the device, but also enables the operator to operate more easily and accurately when adjusting the clamping force and the position of the pipeline, thereby improving the efficiency and quality of the welding work.

[0032] As shown in Figure 1 , Figure 2 , Figure 3As shown, the two sides of the moving mechanism 3 are provided with moving blocks 6, and the two sides of the clamping structure 4 are provided with moving grooves 5, and the moving blocks 6 are slidably connected in the moving grooves 5, so that when the moving mechanism 3 is driven by the second bolt 9, the force can be uniformly transmitted to the clamping structure 4 through the moving blocks 6, thereby realizing the accurate adjustment of the clamping structure 4. At the same time, the two sides of the clamping structure 4 are provided with moving grooves 5, and the moving blocks 6 are slidably connected in the moving grooves 5. This sliding connection not only ensures the stable movement of the moving blocks 6 in the moving grooves 5, but also enables the clamping structure 4 to adaptively adjust according to the moving distance and direction of the moving blocks 6. When the moving blocks 6 slide in the moving grooves 5, the clamping structure 4 can adjust its clamping force and position accordingly, thereby realizing stable clamping of pipes of different sizes. Not only improves the adaptability and flexibility of the device, but also ensures the stability and precision of the pipe during welding.

[0033] As shown in Figure 1 , Figure 2 , Figure 3 , a group of limiting rods 7 are arranged below the moving mechanism 3, and two groups of limiting rods 7 are arranged on the clamping structure 4, and the three groups of limiting rods 7 are arranged in a circular array and are adapted to the clamped pipe, so as to ensure that the moving mechanism 3 will not deviate or shake excessively when adjusting and clamping the pipe. At the same time, two groups of limiting rods 7 are also ingeniously arranged on the clamping structure 4, and the three groups of limiting rods 7 are arranged in a circular array. Such arrangement not only enables the clamping structure 4 to produce more uniform and stable clamping force when clamping the pipe, but also effectively prevents the pipe from rotating or moving due to uneven force during welding. More importantly, the three groups of limiting rods 7 are adapted to the clamped pipe and can be accurately adjusted and fixed according to the actual size and shape of the pipe, thereby ensuring the smooth progress of the welding work and the high standard of the welding quality. Not only improves the stability and reliability of the device, but also greatly improves the efficiency and precision of the welding work.

[0034] As shown in Figure 1 , Figure 2 , Figure 3As shown, the limiting rod 7 is internally threaded with a first bolt 8, and one end of the first bolt 8 abuts against the pipe, so that the first bolt 8 can be firmly connected inside the limiting rod 7 and will not easily loosen or fall off due to external force. At the same time, one end of the first bolt 8 is designed to abut against the pipe. When it is necessary to clamp and fix the pipe, simply tighten the first bolt 8 so that one end abuts tightly against the pipe surface to achieve a stable clamping of the pipe. This abutting method is not only simple and easy to implement, but also ensures that the pipe will not move or shift due to external force during the welding process, thereby ensuring the accuracy and quality of the welding. In addition, since the first bolt 8 and the limiting rod 7 are connected by threads, the extension length of the first bolt 8 can be adjusted according to actual needs to adapt to pipes of different sizes, further improving the flexibility and applicability of the device.

[0035] like Figure 1 , Figure 2 Figure 3 Figure 1 Figure 2 As shown, a handle 2 is provided through the top of the second bolt 9. The handle 2 provides a gripping point for the operator, making it a direct connection point between the operator and the main body 1 of the device. It provides the operator with a stable and comfortable gripping point. At the same time, the presence of the handle 2 not only makes it easy for the operator to tighten the second bolt 9 to adjust the distance between the main body 1 of the device and the movable mechanism 3, thereby achieving precise control of the clamping structure 4, but also ensures that the operator can maintain stability during operation and avoid operational errors caused by hand slippage or fatigue. In addition, the design of the handle 2 also fully considers the ergonomic principle, so that the operator can maintain a comfortable feel even during long-term use, thereby improving work efficiency and welding quality.

[0036] When the pipe needs to be welded, first, the first pipe is placed on the horizontal plane, and the handle 2 is twisted to drive the second bolt 9 to rotate, so that the distance between the device body 1 and the movable mechanism 3 changes, thereby driving the movable block 6 to slide in the movable groove 5. Since the movable groove 5 is an inclined structure as a whole, when the movable block 6 slides in the movable groove 5, the clamping structure 4 can be adjusted according to the size of the pipe. After adjustment, the positioning device can be placed on the first pipe, and then the handle 2 is twisted to drive the second bolt 9 to rotate, so that the movable block 6 on the movable mechanism 3 slides in the movable groove 5, so that the clamping structure 4 clamps the pipe, thereby achieving clamping of the first pipe. Then, the hand wheel 14 is twisted to make the fastening bolt 13 separate from the pressing piece 10, and then the pressing piece 10 is rotated to the side of the first pipe by the position limitation of the positioning bolt 12. Then, the second pipe is placed on the other side of the device body 1 and abuts against one side of the pressing piece 10, and the first bolt 8 on the limiting rod 7 is twisted to make one end of the first bolt 8 abut against the second pipe. Due to the existence of the pressing piece 10, the distance between the pipes in the traditional welding is avoided to be judged by the operator, so as to improve the precision of the pipe welding, improve the effect of the pipe welding, and improve the use convenience of the excavator welding part welding rapid positioning device.

[0037] The advantages of the technical scheme in practical application include but are not limited to the following points:

[0038] 1. The process of manual intervention is avoided, and the precision of welding is improved.

[0039] 2. The distance between the welded pipes is more accurate, and the welding effect is improved.
