Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe cutting technology, specifically a bidirectional guide rail rotary clamping device for steel pipe cutting. Background Technology
[0002] Steel pipes are hollow, long tubular materials made of steel, typically with a circular cross-section, but square, rectangular, and other special shapes are also possible. They are mainly made from carbon steel, alloy steel, and other materials through hot rolling, cold rolling, and cold drawing processes. They possess high strength, good toughness, and strong corrosion resistance, and are widely used in building structures (such as scaffolding and bridge supports), oil and gas transportation, machinery manufacturing (such as automobile drive shafts), and urban water and heating systems. Due to their hollow structure, steel pipes reduce their weight while maintaining load-bearing capacity, combining economy and practicality, making them an indispensable material for modern industry and infrastructure construction.
[0003] In existing technologies, the simplest steel pipe clamping method usually adopts a manual screw clamping structure: by setting a threaded clamping screw on a fixed bracket, the operator manually rotates the screw, causing the clamping block at the front end of the screw (usually an arc or V-shaped structure to fit the outer wall of the steel pipe) to move towards the steel pipe. The mechanical force driven by the screw is used to squeeze and fix the steel pipe in the positioning groove of the bracket. The clamping is achieved by the friction and extrusion stress between the clamping block and the surface of the steel pipe. This method is simple in structure, low in cost, does not require a complex power system, and can fix the steel pipe by manual operation alone.
[0004] Lacking a precise positioning and guiding structure, relying solely on manual visual alignment can easily lead to deviations in parameters such as coaxiality and perpendicularity after the steel pipe is clamped, affecting the accuracy of subsequent processing and making it impossible to clamp the steel pipe efficiently. The clamping force depends on the operator's experience and strength, which can easily result in excessively loose clamping. To address these issues, a bidirectional guide rail rotary clamping device for steel pipe cutting is proposed. Utility Model Content

The first scraper 23 and the second scraper 27 can push the impurities at the bottom of the inner wall of the base 1 into the storage box 33.
[0038] Working principle: Rotating knob 3 drives the first bidirectional threaded rod 4 to rotate. When the first bidirectional threaded rod 4 rotates, the worm gear 5 on it rotates accordingly and meshes with the worm wheel 7, thereby driving the second bidirectional threaded rod 6 to rotate. When the first bidirectional threaded rod 4 and the second bidirectional threaded rod 6 rotate, the fixing block 8 threadedly connected to them moves on the threaded rod, causing the clamps 9 on one side of the fixing block 8 to move closer or further apart, thereby clamping and releasing the steel pipe. The rubber pad 10 on the inner wall of the clamp 9 increases friction, prevents the steel pipe from sliding, and also protects the surface of the steel pipe. The first motor 11 in the base 1 starts, and the output end drives the rotating rod 12 to rotate. The first bevel gear set 13 on the rotating rod 12 rotates accordingly. Through the meshing transmission of the bevel gears, it drives the first lead screw 15 to rotate. When the first lead screw 15 rotates, the sliding plate 16 threadedly connected to it is restrained by the support column 14. The slide plate 16 moves up and down along the screw direction, and the support 17 on the top of the slide plate 16 also moves accordingly. After the cutting is completed, it can prevent the steel pipe from falling off due to insufficient clamping force. During the cutting process, some cutting impurities will fall to the bottom of the inner wall of the base 1. The second motor 18 starts, and the output end drives the connecting rod 19 to rotate. The second bevel gear set 20 on the connecting rod 19 rotates, and the second screw 21 rotates through meshing transmission. When the second screw 21 rotates, the slider 28 threadedly connected to it moves along the screw direction. The frame 22 at the bottom of the slider 28 and the first scraper 23 fixed on the frame 22 move accordingly to clean the bottom of the inner wall of the base 1. At the same time, the telescopic rod 25 and the spring 24 in the frame 22 allow the fixed plate 26 and the second scraper 27 to adapt to different cleaning needs. The second scraper 27 can clean some corners or gaps.
