A fourth push cylinder 29 is provided on the lower end surface of the base 10, and the output end of the fourth push cylinder 29 passes through the base 10 and is fixedly connected to the lower end surface of the second support plate 27. A plurality of second rollers 28 are rotatably provided on the arc-shaped support surface of the second support plate 27. Rotating plates 16 are rotatably provided on both sides of the second support plate 27 on the end surface of the base 10, and a telescopic slide 17 is slidably provided inside each rotating plate 16. Rotating parts 18 are rotatably connected on both sides of the telescopic slide 17, and one end of each rotating part 18 is connected to a first support plate 19, and a plurality of first rollers 20 are rotatably provided inside each first support plate 19.

[0027] Specifically, the second motor 30 and the third motor 31 are ordinary motors, the fourth push cylinder 29 and the fifth push cylinder 32 are ordinary electric push cylinders, hydraulic push cylinders, etc., which are existing technologies and will not be elaborated in this scheme. The output end of the second motor 30 drives the three-jaw chuck 13 to rotate, and the third motor 31 drives the screw rod 33 to rotate. The rotation of the screw rod 33 will drive the movable plate 12 to move horizontally, and the output end of the fifth push cylinder 32 drives the thread turning tool 15 to move horizontally, so that the device can adjust the distance between the three-jaw chuck 13 and the thread turning tool 15 according to the length of the jack push rod, thereby improving the adaptability of the device. The output end of the fourth push cylinder 29 drives the second support plate 27 to move vertically up and down, which not only enables the second support plate 27 to drive the jack push rod to move up and down, thereby facilitating the fixing of the jack push rod on the three-jaw chuck 13, but also enables the second support plate 27 to adjust the clamping height according to the diameter of the jack push rod, thereby improving the adaptability of the device.

[0028] The rotating plate 16 and the telescopic slide 17 are slidably connected, so that the clamp can adjust the combined length of the rotating plate 16 and the telescopic slide 17 according to the diameter of the jack rod, so that the first support plate 19 can clamp the upper side wall of the jack rod.

[0029] The first support plate 19 is rotatably arranged to facilitate adjustment of the clamping angle according to the diameter of the jack rod, so that no matter how much the diameter of the jack rod is, the first support plate 19 can be adjusted to maintain the two first support plates 19 and the second support plate 27 to form a three-point stable clamp on the jack rod, thereby improving the clamping stability of the device.

[0030] The first roller 20 and the second roller 28 are both made of elastic material. The arrangement of the first roller 20 and the second roller 28 enables the first support plate 19 and the second support plate 27 to stably clamp the jack rod without affecting the rotation effect required for the processing of the jack rod itself.

[0031] Further, such as Figure 4 As shown, a plurality of second push cylinders 25 are provided on one side of each telescopic slide 17 , and an output end of each second push cylinder 25 is fixedly connected to one end of the rotating plate 16 .

[0032] Specifically, the second push cylinder 25 is a common hydraulic push cylinder, an electric push cylinder, etc. By adjusting the length of the output end of the second push cylinder 25, the combined length of the rotating plate 16 and the telescopic slide 17 can be adjusted, thereby improving the degree of automation of the device.

[0033] Further, such as Figure 1 As shown, two cross bars 34 are connected between the two brackets 11 , and a third push cylinder 26 is rotatably provided on the lower end surface of each cross bar 34 , and one end of each third push cylinder 26 is rotatably connected to the upper end surface of its adjacent rotating plate 16 .

[0034] Specifically, the third push cylinder 26 is an ordinary hydraulic push cylinder, an electric push cylinder, etc. The output end of the third push cylinder 26 supports the rotating plate 16. The extension and contraction of the output end of the third push cylinder 26 drives the rotating plate 16 to rotate along the rotating connection between the rotating plate 16 and the base 10, thereby driving the first support plate 19 to rotate. After the first support plate 19 clamps the end face of the jack push rod, the output end of the third push cylinder 26 supports the rotating plate 16, driving the first support plate 19 to press down and clamp the outer wall of the jack push rod.

[0035] Further, such as Figure 5 As shown, a plurality of first push cylinders 21 are rotatably connected between the two side walls of each rotating member 18 and the end surface of the first support plate 19 .

[0036] Specifically, the first push cylinder 21 is an ordinary hydraulic push cylinder, an electric push cylinder, etc. The output ends of multiple first push cylinders 21 are synchronously extended and retracted, which can drive the first support plate 19 to deform into different arcs, so that the clamping surface of the first support plate 19 can be adapted and adjusted according to the different sizes of the jack push rod, thereby increasing the contact area between the clamping surface of the clamp and the side wall of the jack push rod, making the clamping stability higher.

[0037] Further, such as Figure 4 As shown, a rotating shaft 23 is provided at the rotating connection between each telescopic slide 17 and the rotating member 18, and the rotating shaft 23 is fixedly connected to the rotating member 18. A first motor 24 is provided inside each telescopic slide 17, and the output end of the first motor 24 is fixedly connected to one end of one of the rotating shafts 23.

[0038] Specifically, the first motor 24 is an ordinary motor. The output end of the first motor 24 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the rotating member 18 to rotate, thereby driving the first support plate 19 to rotate, thereby improving the intelligence of the device.

[0039] First, place the jack rod to be processed on the upper end surface of the second support plate 27, then start the fourth push cylinder 29, the output end of the fourth push cylinder 29 drives the second support plate 27 to move vertically until the axis of the jack rod and the axis of the three-jaw chuck 13 are on the same horizontal axis, then start the third motor 31, the output end of the third motor 31 drives the screw rod 33 to rotate, the rotation of the screw rod 33 will drive the movable plate 12 to move horizontally, start the three-jaw chuck 13 to clamp one end of the jack rod, and then start the second push cylinder 25 according to the diameter of the jack rod, and adjust the rotation by telescoping the output end of the second push cylinder 25 The combined length of the plate 16 and the telescopic slide 17 makes the length of the entire rotating clamping arm adapt to the clamping of the jack push rod by the first support plate 19, and the first motor 24 and the first push cylinder 21 are started at the same time. The output end of the first motor 24 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the rotating part 18 to rotate, thereby driving the first support plate 19 to rotate until the two first support plates 19 and the second support plates 27 form a triangular clamp on the outer wall of the jack push rod. The cooperation of multiple first push cylinders 21 changes the curvature of the clamping surface of the first support plate 19 until the curvature of the clamping surface of the first support plate 19 is adapted to the curvature of the outer wall of the jack push rod.

[0040] Finally, the two third push cylinders 26 are started, and the output ends of the third push cylinders 26 press down the rotating plate 16, thereby pressing down the entire clamping arm, so that the two first support plates 19 and the second support plates 27 clamp the jack rod at three points.

[0041] Example 2:

[0042] On the basis of the first embodiment, a further embodiment is made, such as Figure 5 As shown, a vibration detector 22 is provided on one side of each first support plate 19 .

[0043] Specifically, the vibration detector 22 is an ordinary vibration sensor, which is an existing technology and will not be elaborated in detail in this solution. The setting of the vibration detector 22 can receive the vibration generated by the jack rod during processing, and adjust the clamping force of the clamp according to the intensity of the vibration, so that the vibration of the jack rod is reduced and the processing accuracy is improved.

[0044] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0045] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.
