Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the device includes a bottom plate 1 and a slide 2, the slide 2 is slidably connected to the inside of the bottom plate 1, a guide plate 3 is fixedly arranged on the left side of the inside of the bottom plate 1, a clamping assembly 4 is fixedly arranged on the top of the slide 2, the clamping assembly 4 includes a first motor 401 fixedly arranged on the right side of the top of the slide 2, an external fixed sleeve at the head end of the first motor 401 is provided with a cam 402, a rotating plate 403 is connected to the front and rear ends of the left side of the top of the slide 2, a first spring 404 is fixedly arranged on the right side between the two rotating plates 403, and the left side of the outer wall of the rotating plate 403 A shell 405 is fixedly provided, and a first slide plate 406 is slidably connected inside the shell 405. A guide rod 407 fixedly provided on the inner side of the first slide plate 406 slides through the rotating plate 403. A clamp 408 is fixedly provided on the end of the guide rod 407 away from the first slide plate 406. A push rod 409 fixedly provided on the outer wall of the first slide plate 406 penetrates the shell 405. A first pressure sensor 410 is fixedly provided on the outer wall of the shell 405. A baffle 411 is fixedly provided on the left side of the top of the slide seat 2. A controller 412 is fixedly provided on the outer wall of the shell 405.

[0027] First, the steel pipe passes through the guide plate 3 and moves to the position between the rotating plates 403. The blocking effect of the baffle 411 can prevent the steel pipe from contacting the cam 402. The staff then turns on the first motor 401. The first motor 401 drives the cam 402 to squeeze two rotating plates 403 to rotate, so that the rotating rotating plates 403 together with the shell 405, the guide rod 407 and the chuck 408 clamp the steel pipe, and the first spring 404 is deformed. Through the reaction force of the steel pipe, the chuck 408 drives the guide rod 407 together with the first slide plate 406 and the push rod 409 to apply squeezing force to the first pressure sensor 410. The first pressure sensor 410 transmits the monitored squeezing force value to the controller 412 until the value displayed by the controller 412 meets the staff's needs. The staff then turns off the first motor 401. At this time, the clamping force of the chuck 408 on the steel pipe is within the required range of the staff.

[0028] Example 2

[0029] like Figure 1 , Figure 2 , Figure 3As shown, a plurality of balls 5 are connected to the upper end of the guide plate 3, a second motor 6 is fixedly arranged on the right side of the base plate 1, a screw rod 7 is fixedly arranged on the left side of the second motor 6, the screw rod 7 rotates and penetrates the base plate 1, and the screw rod 7 is connected to the guide plate 3, and the screw rod 7 is threadedly penetrated by the slide seat 2, a clearance hole 8 is integrally arranged inside the housing 405, the clearance hole 8 is a through hole design, and the clearance hole 8 is sleeved on the outside of the top rod 409, and a second spring 13 is fixedly arranged on the left and right sides of the inner side of the first slide plate 406, and the second spring 13 is away from the first slide plate 406. One end of a slide plate 406 is fixedly connected to the rotating plate 403, and a third motor 9 is fixedly provided on the outside of the shell 405. A connecting rod 10 fixed at the head end of the third motor 9 rotates and passes through the shell 405. The connecting rod 10 passes through the first slide plate 406 and the guide rod 407 in sequence. The outer diameter of the connecting rod 10 is smaller than the inner diameter of the guide rod 407. A second slide plate 11 is slidably connected to the inside of the shell 405. The second slide plate 11 is threadedly sleeved on the outside of the connecting rod 10, and a second pressure sensor 12 is fixedly provided on the inner side of the second slide plate 11.

[0030] According to the operation mode in Example 1, when the push rod 409 applies the squeezing force to the first pressure sensor 410, the first slide plate 406 pulls the second spring 13 to deform. When the clamping force of the chuck 408 on the steel pipe is adjusted, the staff first turns off the first motor 401, and then turns on the forward rotation function of the third motor 9. The third motor 9 drives the connecting rod 10 to rotate. Through the threaded transmission of the connecting rod 10 and the second slide plate 11, the second slide plate 11 moves along the direction of the first slide plate 406 until the first slide plate 406 applies the squeezing force to the second pressure sensor 12. The third motor 9 stops running. At this time, the second slide plate 11 limits the displacement of the first slide plate 406, thereby locking the current clamping force of the chuck 408 on the steel pipe. The staff then turns on the forward rotation of the second motor 6. The second motor 6 drives the screw rod 7 to rotate. Through the threaded transmission of the screw rod 7 and the slide seat 2, the slide seat 2 drives the chuck 408 and the steel pipe to move along the right direction of the bottom plate 1, thereby stretching the steel pipe. The ball 5 can be in a state of rolling friction with the steel pipe being stretched.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
