DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 5 A positioning fixture for high-pressure oil pipe processing includes a base 1, a support frame 2 is fixedly installed on the base 1, a placement groove is opened on the support frame 2, and a measuring component for measuring the length of the oil pipe is provided on the base 1. During processing, the high-pressure oil pipe is placed in the placement groove opened on the support frame 2.

[0025] A U-shaped mounting frame 3 is fixedly mounted on the support frame 2, a threaded hole is provided on the mounting frame 3, a first threaded rod 4 is vertically threadedly inserted in the threaded hole, a first adjusting block 5 is fixedly sleeved on the first threaded rod 4, a U-shaped limiting plate 6 is rotatably mounted on the lower end of the first threaded rod 4, a rotating groove is provided at both ends of the limiting plate 6, and pressure wheels 7 are rotatably mounted in the two rotating grooves, a limiting component for limiting the rotation of the two pressure wheels 7 is provided on the first threaded rod 4, a through hole is provided at one end of the first threaded rod 4, and the limiting component includes a vertical sliding member that slides vertically through a sliding member A lifting plate 10 installed on the limiting plate 6, a second threaded rod 11 inserted in the through hole, a connecting block 12 threadedly sleeved on the second threaded rod 11, and a second adjusting block 13 fixedly installed at one end of the second threaded rod 11, the connecting block 12 is fixedly installed on the upper end of the first threaded rod 4, one end of the second threaded rod 11 is rotatably connected to the lifting plate 10, a plurality of slide grooves are provided on the limiting plate 6, and the sliding component includes two slide rods 14 symmetrically fixedly installed on the limiting plate 6, and the two ends of the two slide rods 14 are respectively slidably inserted in the plurality of slide grooves;

[0026] When clamping and fixing the high-pressure oil pipe, the lifting plate 10 contacts with the two pressure wheels 7. Under the action of the friction force between the lifting plate 10 and the pressure wheels 7, the rotation of the pressure wheels 7 is limited. When the high-pressure oil pipe is placed on the support frame 2, the first adjusting block 5 is rotated to drive the first threaded rod 4 to move vertically downward, and then the limiting plate 6 is driven by the first threaded rod 4 to move vertically downward. The limiting plate 6 approaches the direction of the high-pressure oil pipe until the limiting plate 6 drives the two pressure wheels 7 to contact the surface of the high-pressure oil pipe. Since the lifting plate 10 limits the rotation of the pressure wheels 7, the high-pressure oil pipe is clamped and fixed by the support frame 2, the limiting plate 6 and the pressure wheels 7.

[0027] During the processing, when the high-pressure oil pipe needs to be rotated, the second adjusting block 13 can be rotated, and under the action of the connecting block 12, the lifting plate 10 is driven to move vertically upward. At this time, the lower surface of the lifting plate 10 is separated from the pressure wheel 7, and the restriction on the pressure wheel 7 is released. Then the high-pressure oil pipe can be rotated, driving the high-pressure oil pipe to rotate between the support frame 2 and the limit plate 6 until it rotates to a suitable processing position, and then the high-pressure oil pipe is restricted by the limiting component. There is no need to repeatedly fix the high-pressure oil pipe. The operation is simple and convenient, and the processing efficiency is effectively improved.

[0028] Anti-skid pads are symmetrically fixedly installed on the lower surface of the lifting plate 10. The two anti-skid pads are respectively located directly above the two pressure wheels 7. When the lifting plate 10 contacts the two pressure wheels 7, the anti-skid pads can increase the friction between the lifting plate 10 and the pressure wheels 7, thereby playing a better restrictive role.

[0029] The inner wall of the placement groove is symmetrically provided with rolling grooves, and rollers 8 are rotatably installed in both rolling grooves. When the high-pressure oil pipe rotates in the placement groove, the rollers 8 can reduce the friction between the placement groove and the high-pressure oil pipe.

[0030] A limiting hole is provided on the mounting frame 3, and a limiting rod 9 is vertically slidably installed in the limiting hole. One end of the limiting rod 9 is fixedly connected to the upper surface of the limiting plate 6. When the first threaded rod 4 drives the limiting plate 6 to move vertically downward, the limiting rod 9 can prevent the limiting plate 6 from rotating.

[0031] The measuring assembly includes a slide rail 15 fixedly mounted on the base 1, a slider 17 slidably mounted on the slide rail 15 via a telescopic spring 16, a baffle 18 fixedly mounted on the slider 17, and an indicator rod 19 fixedly mounted on the baffle 18. The side of the slide rail 15 is engraved with scale values, and one end of the indicator rod 19 points to the scale value.

[0032] When processing the high-pressure oil pipe, one end of the high-pressure oil pipe is facing the baffle 18, and the baffle 18 is pushed to move on the slide rail 15. The telescopic spring 16 is compressed, and the baffle 18 will drive the indicator rod 19 to move during the movement. The distance between the support frame 2 and the baffle 18 can be judged by observing the scale value indicated by the indicator rod 19. When the high-pressure oil pipe needs to be cut, it is convenient to cut out the high-pressure oil pipe of the required length.

[0033] In the utility model, when the high-pressure oil pipe is clamped and fixed, the two pressure wheels 7 are driven to contact the high-pressure oil pipe through the limit plate 6, and then the rotation of the two pressure wheels 7 is limited by the limiting component, so that the high-pressure oil pipe is clamped and fixed by the support frame 2, the limit plate 6 and the pressure wheel 7. During the processing, when the high-pressure oil pipe needs to be rotated, the restriction of the pressure wheel 7 by the limiting component can be released, and the high-pressure oil pipe can be rotated, driving the high-pressure oil pipe to rotate between the support frame 2 and the limit plate 6 until it is rotated to a suitable processing position, and then the high-pressure oil pipe is limited by the limiting component. There is no need to repeatedly fix the high-pressure oil pipe. The operation is simple and convenient, and the processing efficiency is effectively improved.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
