Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a steel pipe positioning and adjusting mechanism. Background Art

[0002] Steel pipe is a steel material with a hollow section whose length is much larger than its diameter or circumference. According to the cross-sectional shape, it can be divided into round, square, rectangular and special-shaped steel pipes; according to the material, it can be divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe; according to the production process, it can be divided into seamless steel pipe and welded steel pipe, of which seamless steel pipe can be divided into hot rolling and cold rolling (drawing), and welded steel pipe can be divided into straight seam welded steel pipe and spiral seam welded steel pipe.

[0003] Round steel pipes are the most common pipes in life. During the processing of round steel pipes, two sections of steel pipes need to be welded. However, the existing welding method is to directly connect the two ends of the pipe end to end for welding, which can easily lead to the situation that the two ends of the steel pipes are not welded on the same axis, greatly affecting the welding effect. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is that it is inconvenient to position and adjust two sections of steel pipes during welding, which greatly affects the welding effect.

A driven pulley is fixedly sleeved on the outer wall of the positioning sleeve on one side. A transmission belt is arranged between the driving pulley and the driven pulley.

[0010] As an improvement, through holes cooperating with the linkage rod are also arranged on the two adjusting rings.

[0011] As an improvement, a dial block is arranged on one side of the linkage rod.

[0012] (III) Beneficial effects

[0013] The advantages of the present utility model compared with the prior art are as follows:

[0014] (1) By driving the two side gears to rotate synchronously through the adjusting mechanisms on both sides, and driving the corresponding positioning clamping arms to swing synchronously by the two side gears, the steel pipes on both sides can be positioned in the two positioning sleeves, so that the steel pipes on both sides are coaxial. By pushing the steel pipes on both sides to butt joint through the electric push rod, the coaxial positioning of the steel pipes is realized.

[0015] Start the rotating mechanism to drive the positioning sleeve to rotate. With the cooperation of the linkage rod, the two positioning sleeves drive the two sections of steel pipes to rotate synchronously, so that the steel pipes can be spot welded first to preliminarily connect the two steel pipes. After the steel pipes are preliminarily fixed, push the linkage rod to one side and drive the rotating mechanism again to drive the steel pipes to rotate, which is convenient for welding and fixing the entire weld seam.

Specific implementation manners

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 4 shown, a steel pipe positioning and adjusting mechanism includes a processing base 1. Fixed vertical plates 2 and sliding vertical plates 3 are respectively arranged on both sides of the processing base 1. An electric push rod 4 for driving the sliding vertical plate 3 to slide is fixedly connected to the processing base 1. Positioning sleeves 5 arranged coaxially are rotatably connected to both the fixed vertical plate 2 and the sliding vertical plate 3. At least one gear 6 arranged in an annular array is rotatably connected to the inner walls of the positioning sleeves 5. A positioning clamping arm 7 is fixedly connected to one side of each gear 6. An adjusting mechanism for driving the gears 6 to swing synchronously is provided on both positioning sleeves 5. The adjusting mechanism includes a fixed ring 8 fixedly connected to one end of the positioning sleeve 5. A telescopic cylinder 10 is fixedly connected to the fixed ring 8. The output end of the telescopic cylinder 10 is fixedly connected to an adjusting ring 9 located on one side of the fixed ring 8. At least one rack 18 meshing with the gear 6 is fixedly connected to the inner side of the adjusting ring 9.

[0023] At least one linkage jack 12 penetrating through is provided on both positioning sleeves 5. A linkage rod 11 is slidably inserted into both linkage jacks 12. Through holes cooperating with the linkage rod 11 are also provided on both adjusting rings 9. A dial block 17 is provided on one side of the linkage rod 11. A rotating mechanism for driving the corresponding positioning sleeve 5 to rotate is provided on the fixed vertical plate 2. The rotating mechanism includes a motor 13 fixedly connected to one side of the fixed vertical plate 2. The output end of the motor 13 is fixedly connected to a driving pulley 14. A driven pulley 15 is fixedly sleeved on the outer wall of one positioning sleeve 5. A transmission belt 16 is provided between the driving pulley 14 and the driven pulley 15.

[0024] In specific use, two steel pipes to be welded are respectively inserted into the positioning sleeves 5 on both sides. The telescopic cylinders 10 on both sides are started to pull the adjusting disks on both sides close to the positioning sleeves 5, pushing the racks 18 to drive the corresponding gears 6 to rotate. The gears 6 drive the corresponding positioning clamping arms 7 to swing synchronously, pushing and clamping the steel pipes on both sides at the axis of the positioning sleeves 5, keeping the steel pipes on both sides coaxial. The electric push rod 4 is started to pull the sliding vertical plate 3 to drive one steel pipe to butt against the other steel pipe. The welding device first passes through the gap between the adjacent linkage rods 11 to perform spot welding on the two steel pipes, enabling the two steel pipes to be preliminarily connected. At the same time, the motor 13 drives the driving pulley 14 to rotate. The driving pulley 14 drives the driven pulley 15 to rotate under the drive of the transmission belt 16. The driven pulley 15 drives the positioning sleeve 5 on one side to rotate. Under the connection of the linkage rods 11, the positioning sleeves 5 on both sides drive the two steel pipes to rotate synchronously, achieving spot welding at multiple positions on the two steel pipes. After preliminary welding, the dial block 17 is toggled to push the linkage rod 11 to slide along the communication jack, moving the communication rod to one side without blocking the welding position. The rotating mechanism is started again to drive the steel pipe to rotate, and then the entire weld can be welded.
