[0028] REFERENCE Figures 1-4A kind of steel pipe installation's calibration butt joint device, including base 1, movable seat 4 and positioning clamping plate 11;

[0029] Base 1 is the basic support component of the whole device, it is made of high-strength steel material, to ensure that it has sufficient strength and stability to carry subsequent components and the steel pipe to be butt jointed.The top of base 1 is symmetrically fixed with first guide rail 2 on both sides, and the first guide rail 2 is fixed with base 1 by welding or bolt connection, and a first sliding groove 8 is formed in the first guide rail 2, and the shape and size of the first sliding groove 8 are accurately designed to match the first sliding block 16 at the bottom of the subsequent movable seat 4.

[0030] Among them, the second guide rail 3 is fixedly installed on the top of the base 1 and between the two groups of first guide rails 2, and is also fixed by welding or bolt connection.The second guide rail 3 is provided with a second sliding groove 7, and the inner space of the second sliding groove 7 is used to install a lead screw 6, which is rotatably installed in the second sliding groove 7 through a bearing, to ensure that the lead screw 6 can rotate smoothly.

[0031] Secondly, a servo motor 5 is fixedly installed on the middle of the outer wall of the base 1 on one side, and the output shaft of the servo motor 5 is connected with the lead screw 6 through a shaft coupling.When the servo motor 5 is powered on, the rotary motion of the output shaft can be accurately transmitted to the lead screw 6, so as to drive the lead screw 6 to rotate.At the same time, the other end of the lead screw 6 extends out of the second guide rail 3 and is fixedly installed with a hand wheel 20, and the surface of the hand wheel 20 is provided with anti-skid lines, so that the operator can drive the lead screw 6 to rotate by rotating the hand wheel 20 when power failure occurs or manual adjustment is needed, thereby increasing the flexibility of the device.

[0032] Reference Figures 1-5 The movable seat 4 is provided with two groups, and the two groups of movable seats 4 are movably and symmetrically installed on both sides of the top of the first guide rail 2 and the second guide rail 3.The first sliding block 16 is symmetrically arranged on the bottom of the movable seat 4, and the first sliding block 16 is slidably installed in the first sliding groove 8 of the first guide rail 2, so that the movable seat 4 can stably slide along the first guide rail 2 in a straight line.At the same time, the second sliding block 17 is arranged in the middle of the bottom of the movable seat 4, the second sliding block 17 is slidably installed in the second sliding groove 7 of the second guide rail 3, and a threaded hole 18 is horizontally and throughly formed in the second sliding block 17, and the lead screw 6 penetrates the threaded hole 18 and is threadedly engaged.Because the threads on both sides of the lead screw 6 are opposite, when the lead screw 6 rotates, the two groups of movable seats 4 will move towards or away from each other under the drive of the lead screw 6 along the second guide rail 3, so as to realize the adjustment of different distances, to adapt to the butt joint requirements of steel pipes of different lengths.

[0033] The top of the movable seat 4 is provided with a T-shaped sliding groove 10, and a T-shaped sliding block 19 is slidably installed in the T-shaped sliding groove 10. The T-shaped sliding block 19 can freely slide in the T-shaped sliding groove 10, further adjusting the position of the positioning clamping plate 11, and improving the flexibility and adaptability of the device.

[0034] Reference Figure 1 And Figure 4 The number of positioning clamping plates 11 is two groups, and the two groups of positioning clamping plates 11 are respectively detachably installed on one side of the top of the movable seat 4 and the top of the T-shaped sliding block 19. The specific installation method is that: the bottom of the positioning clamping plate 11 is provided with installation holes 14 on both sides, the top of the T-shaped sliding block 19 and the top of one end of the movable seat 4 are both fixedly installed with bolts 13, the bolts 13 penetrate the installation holes 14, and the fastening nuts 15 are rotatably connected above the bolts 13. By tightening the fastening nuts 15, the positioning clamping plate 11 can be firmly installed on the movable seat 4 or the T-shaped sliding block 19; when it is necessary to replace the positioning clamping plate 11 or to maintain, it can be easily disassembled by loosening the fastening nuts 15.

[0035] The inner wall of the positioning clamping plate 11 movably embeds a plurality of groups of rolling balls 12, and each group of rolling balls 12 is equidistantly distributed on the inner wall of the positioning clamping plate 11. The existence of the rolling balls 12 can reduce the friction between the positioning clamping plate 11 and the surface of the steel pipe when clamping the steel pipe, avoid damaging the surface of the steel pipe, and also facilitate fine adjustment of the steel pipe during butt joint.

[0036] Secondly, the top of the two groups of first guide rails 2 is fixedly installed with a support seat 9, and the top of the support seat 9 is usually designed as an arc shape matched with the outer surface of the steel pipe, which is used for preliminary supporting and positioning of the steel pipe during butt joint, and ensures that the steel pipe is in a relatively stable state during butt joint.

[0037] Working principle: first, make the device horizontal by adjusting the adjustable supporting feet at the bottom of the base 1 if there is relevant design, to ensure the accuracy of butt joint, then place the two steel pipes to be butt jointed between the two groups of positioning clamping plates 11, and preliminarily support them by the support seat 9, next, the driving mode can be selected according to actual needs, if the electric mode is used, start the servo motor 5, the servo motor 5 drives the screw rod 6 to rotate, because the threads on both sides of the screw rod 6 are opposite, the two groups of movable seats 4 will move towards each other, so that the positioning clamping plate 11 gradually clamps the steel pipe, if manual adjustment is needed in special circumstances, turn the hand wheel 20, the movement of the movable seat 4 and the clamping of the steel pipe can also be realized, in the clamping process, the rolling balls 12 on the inner wall of the positioning clamping plate 11 contact with the surface of the steel pipe, reducing the friction while ensuring effective clamping of the steel pipe, at the same time, the position of the positioning clamping plate 11 can be further adjusted by sliding the T-shaped sliding block 19, so that the butt joint of the two steel pipes reaches the state of accurate alignment, when the steel pipe butt joint calibration is completed, the subsequent welding or other fixing operation can be carried out.
