[0027] The adjustable V-block assembly 5 includes a slide rail 501 arranged in the middle of the top end of the V-block mounting plate 3, two side support blocks 502 are symmetrically arranged on both sides of the top end of the V-block mounting plate 3, the sides of the side support blocks 502 are each provided with a bottom connecting block 503, the top end of the bottom connecting block 503 is provided with a driving connecting block 504, the top end of the driving connecting block 504 is engaged with a clamping resistance block 505, and two side connecting rings 506 are symmetrically arranged on both sides of the driving connecting block 504.
[0028] Two middle connecting blocks 507 are arranged on the side of the driving connecting block 504, and a driving screw 508 is rotatably inserted through the middle of the side support block 502. The end thread of the driving screw 508 passes through the side connecting ring 506 and the driving connecting block 504, and passes through the middle of the middle connecting block 507 in turn. Two side sliding blocks 509 are sleeved in the middle of the driving screw 508.
[0029] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the slide rail 501 sequentially passes through the side support block 502 , the bottom connecting block 503 and the bottom end of the middle connecting block 507 , and the bottom connecting block 503 is slidably arranged on the slide rail 501 .
[0030] The side support blocks 502, the bottom connection block 503 and the middle connection block 507 are limited to the same straight line.
[0031] Embodiment 3: The difference between this embodiment and embodiment 1 is that the top end of the clamping and resisting block 505 is inclined, and the two clamping and resisting blocks 505 are arranged to be relatively inclined.
[0032] The top ends of the two clamping and abutting blocks 505 can together form a V-shaped supporting surface.

[0035] In this embodiment, the following problems exist in the processing of tubing heads and casing heads in the prior art: First, the tubing heads have many oil holes and inclined holes during processing, and the sealing requirements of the threads are also high, which makes it impossible for general equipment to process them, and even if the shape accuracy is processed, it cannot be guaranteed; Second, the tubing heads need to be processed horizontally because they have inclined surfaces and oil holes at various angles, which requires two or more V-blocks, and the tooling details are relatively large, and the versatility is not strong; Third, the tubing heads need to be processed horizontally because they have inclined surfaces and oil holes at various angles, and there is a drop between the two flanges, which requires two V-blocks of different heights, and the tooling details are relatively large, the versatility is not strong, and the calibration is complicated. Therefore, the existing tubing head and casing head processing technology does not have the ability of rapid debugging and production, and thus needs to be improved.
[0036] In summary, in the specific implementation, when the user needs to support the bottom of the processed oil pipe head or casing head, the user can use the connecting ball lock 4 provided on the V-block mounting plate 3 to enable the connecting ball lock 4 to be inserted into the ball lock mounting hole 6 or the ball lock connecting groove 7 provided on the fixed base plate 2, thereby positioning and connecting the position between the V-block mounting plate 3 and the fixed base plate 2, and realizing the locking and positioning functions at the same time.

[0038] The top of the clamping resistance block 505 is relatively inclined, and the two clamping resistance blocks 505 can together form a V-shaped support surface, so as to better resist and clamp the oil pipe head to be supported and clamped thereon. The clamping resistance blocks 505 can adjust the distance between them according to the size of the oil pipe head to be supported and clamped, so as to expand the device's rapid debugging and clamping support for the oil pipe head, with stronger versatility, easier assembly, and more convenient use.
