Description

Technical Field

[0001] This utility model relates to the field of oil pipe processing technology, and in particular to a quick clamping fixture for oil pipe processing. Background Technology

[0002] Oil pipes, as critical pipelines specifically designed for transporting oil, are used in numerous industrial fields. In the actual processing of oil pipes, it is often necessary to weld two oil pipes together. During the welding process, the oil pipes must remain absolutely stable, because any slight shaking or displacement may lead to welding defects, such as uneven welds, porosity, or cracks. Therefore, clamping fixtures are required to position the oil pipes and ensure their stability.

[0003] In existing technologies, when welding two oil pipes, a positioning fixture is needed to align and fix their positions for welding. However, existing fixtures often use fixed slots or single-specification clamping structures. When dealing with oil pipes with large diameter differences, the fixture components need to be frequently changed. When using a fixture with mismatched dimensions, the contact area between the clamping plate and the oil pipe is small, resulting in insufficient friction to ensure the stability of the oil pipe. This can easily cause the oil pipe to wobble and shift during welding, affecting the welding quality. Therefore, it is necessary to improve the quick-clamping fixture for oil pipe processing to solve the above problems. Utility Model Content

[0004] To overcome the problem that existing clamps cannot adapt to oil pipes with large diameter differences and it is difficult to guarantee the contact area.

[0005] The technical solution of this utility model is as follows: a quick clamping fixture for oil pipe processing, including a positioning plate and a connecting rod fixedly connected to the positioning plate, and also including an electric telescopic rod fixedly connected to the bottom of the positioning plate, a connecting plate fixedly connected to the end of the electric telescopic rod away from the positioning plate, a fixing rope fixedly connected to the connecting plate, a sliding rod slidably connected to the positioning plate, a support rod fixedly connected to the sliding rod, and an adjustment component installed on the positioning plate, which drives the sliding rod and the support rod to slide.

[0006] Preferably, the positioning plate has a matching groove at the corresponding position of the sliding rod, and the sliding rod slides inside the groove.

[0007] Preferably, the positioning plate has a through hole at the corresponding position of the fixing rope, and the fixing rope passes through the through hole.

[0008] Preferably, two positioning plates are provided, and the two positioning plates are installed on the connecting rod by a connector.

[0009] Preferably, the adjustment assembly includes a mounting plate fixedly connected to the positioning plate, a bidirectional threaded rod rotatably connected to the mounting plate, a timing frame threadedly connected to the bidirectional threaded rod, a pointer fixedly connected to the sliding rod, and a scale fixedly connected to the positioning plate. The rotation of the bidirectional threaded rod drives the sliding rod to slide through the timing frame.

[0010] Preferably, two timing frames are provided, and the two timing frames are symmetrically arranged on the bidirectional threaded rod, with the timing frames fixedly connected to the bottom of the sliding rod.

[0011] Preferably, the pointer and the scale are positioned correspondingly.

[0012] The beneficial effects of this utility model are:

[0013] 1. By attaching and tightening the oil pipe with several fixing ropes, the oil pipe can be stably positioned on the support rod. The fixing ropes also provide sufficient friction to fix the oil pipe in place, which can effectively prevent loosening during welding, ensure stability, guarantee welding quality, and allow for quick clamping.

[0014] 2. By using a pointer in conjunction with a ruler, the adjustment position of the support rod can be precisely controlled, so that when welding multiple oil pipes, the oil pipes can be positioned at the same height on the support rod. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5This utility model provides an embodiment of a quick clamping fixture for oil pipe processing, including a positioning plate 1 and a connecting rod 4 fixedly connected to the positioning plate 1. It also includes an electric telescopic rod 21 fixedly connected to the bottom of the positioning plate 1, a connecting plate 22 fixedly connected to the end of the electric telescopic rod 21 away from the positioning plate 1, a fixing rope 23 fixedly connected to the connecting plate 22, a sliding rod 24 slidably connected to the positioning plate 1, a support rod 25 fixedly connected to the sliding rod 24, and an adjustment assembly mounted on the positioning plate 1. The adjustment assembly drives the sliding rod 24 and the support rod 25 to slide, and the adjustment assembly... The sliding rod 24 is driven, and the two supporting rods 25 are adjusted to a suitable position according to the diameter of the oil pipe, so that the oil pipe is between the supporting rod 25 and the fixing rope 23. The connecting plate 22 is pushed by the electric telescopic rod 21, and the connecting plate 22 pulls the fixing rope 23, so that the fixing rope 23 is close to the oil pipe. The fixing rope 23, together with the supporting rod 25, positions the pipe. The two oil pipes are positioned on the two positioning plates 1 respectively, so that the connection of the two oil pipes is in the corresponding position of the connecting rod 4. Because the height of the connecting rod 4 is lower than that of the supporting rod 25, welding can be performed at the connection of the connecting rod 4.

[0023] Please see Figures 1-3 , Figure 5 In this embodiment, the positioning plate 1 has a matching groove at the corresponding position of the sliding rod 24, and the sliding rod 24 slides inside the groove. The groove allows the sliding rod 24 to slide stably, avoiding jamming caused by the tilting of the sliding rod 24. The movement is smooth and the adjustment accuracy is higher. The positioning plate 1 has a through hole at the corresponding position of the fixing rope 23, and the fixing rope 23 passes through the through hole and is guided by the through hole. The material of the fixing rope 23 can be nylon, steel wire, etc., depending on the actual application. There are two positioning plates 1, and the two positioning plates 1 are installed on the connecting rod 4 through the connector. The two positioning plates 1 can be used to position the two oil pipes respectively, so that the two oil pipes can be connected. The positioning plate 1 can be detached and used alone, or multiple positioning plates 1 can be used as needed and connected by the connecting rod 4. The connector can be bolts or other connectors, which can be selected according to the actual use needs.

[0024] Please see Figures 1-4In this embodiment, the adjustment assembly includes a mounting plate 31 fixedly connected to the positioning plate 1, a bidirectional threaded rod 32 rotatably connected to the mounting plate 31, a timing frame 33 threadedly connected to the bidirectional threaded rod 32, a pointer 34 fixedly connected to the sliding rod 24, and a scale 35 fixedly connected to the positioning plate 1. The rotation of the bidirectional threaded rod 32 drives the sliding rod 24 to slide through the timing frame 33. The rotation of the bidirectional threaded rod 32 drives the timing frame 33 to move through the threaded pair. The threaded pair can self-lock, which is a common technical means in the prior art, so it will not be described in detail. The position of the support rod 25 can be adjusted. The support rod 25 is adjusted appropriately according to the diameter of the oil pipe. Two synchronous brackets 33 are provided, and the two synchronous brackets 33 are symmetrically arranged on the bidirectional threaded rod 32. The synchronous brackets 33 are fixedly connected to the bottom of the sliding rod 24. By symmetrically arranging the two synchronous brackets 33, the adjustment can be made synchronously by rotating the bidirectional threaded rod 32. The pointer 34 and the scale 35 are positioned correspondingly. The cooperation between the pointer 34 and the scale 35 can make the position adjustment of the support rod 25 more precise. Thus, when using multiple positioning plates 1, the positions of the support rods 25 on several positioning plates 1 can be made to correspond, so that the oil pipe is at the same height.

[0025] During operation, the double-threaded rod 32 is twisted to drive the timing frame 33, which in turn drives the sliding rod 24. The sliding rod 24 then drives the support rod 25, adjusting it to the appropriate position. As the sliding rod 24 slides, it drives the pointer 34, which corresponds to the value on the scale 35, serving as a reference for the distance the support rod 25 can move. The oil pipe is then placed between the support rod 25 and the fixing rope 23. The electric telescopic rod 21 is activated to drive the connecting plate 22, which pulls the fixing rope 23, causing it to adhere to the oil pipe and fix its position. The connecting rod 4 is positioned lower than the support rod 25, ensuring that the welding position of the oil pipe is at the corresponding position of the connecting rod 4. This prevents the connecting rod 4 from interfering with the welding process.

[0026] Through the above steps, and with several fixing ropes 23 attached to the oil pipe, sufficient friction can be provided to fix the oil pipe, which can effectively prevent loosening during welding and solve the problem that existing clamps cannot adapt to oil pipes with large diameter differences and it is difficult to guarantee the contact area.
