[0002] With the development of modern machining industry, the requirements for cutting quality and precision are constantly increasing, as are the demands for improved production efficiency, reduced production costs, and highly intelligent automatic cutting functions. The development of CNC cutting machines must adapt to the requirements of modern machining industry. Cutting machines are categorized into flame cutting machines, plasma cutting machines, laser cutting machines, water jet cutting machines, etc.

[0003] Existing cutting equipment has the following drawbacks when processing and cutting columnar steel structures. Because the outer wall of the columnar steel structure is smooth, the vibration generated by the ordinary clamping mechanism during cutting may cause the steel structure to shift, resulting in deviation of the cutting position. Secondly, when grooving the outer side of the columnar steel structure, manual rotation is required, which can easily cause the cutting position to deviate circumferentially, affecting the cutting progress. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device for steel structure processing, which solves the problems of smooth outer walls of columnar steel structures, vibration generated by ordinary clamping mechanisms during cutting, which may cause displacement of the steel structure and deviation of the cutting position; and the need for manual rotation when grooving the outer side of columnar steel structures, which may easily cause the cutting position to deviate circumferentially and affect the cutting progress.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for steel structure processing, comprising: a base; a cutting machine disposed on the base, wherein the cutting machine is movably connected to the middle of the rear end of the base via a torque spring and a rotating shaft, for cutting steel structures; a limiting mechanism disposed on the upper surface of the base for limiting and clamping columnar steel; the limiting mechanism includes a transmission support, two sleeves symmetrically mounted on the transmission support and rotatable, and a fixing ring fixedly mounted to the end of each sleeve; a plurality of clamping airbags uniformly embedded inside each sleeve, wherein each clamping airbag is annular, and the clamping airbags located inside the same sleeve are interconnected through air pipes; an air supply structure is installed on the base for inflating and deflating the clamping airbags; and an adjustment mechanism installed on the base, which, under the action of the adjustment mechanism, can drive the limiting mechanism to rotate.

[0006] Preferably, the air supply structure includes: a connecting pipe and an air pump installed at the lower part of the base, wherein one end of the connecting pipe is connected to the output end of the air pump; and an annular pipe respectively surrounding the outside of the two sleeves, wherein one end of the annular pipe is connected to the connecting pipe, and the other end passes through the corresponding sleeve and is connected to one of the clamping airbags, and is used for inflating and deflating several clamping airbags when the air pump is running.

[0007] Preferably, the annular tube is a compressible foldable tube.

[0008] Preferably, the transmission support includes: sliding grooves respectively formed on opposite sides of the two fixed rings, each sliding groove having a concave cross-section; a set of left-right symmetrical fixing strips fixed on the upper surface of the base; and two sliding strips disposed on opposite sides of the two fixing strips, wherein both sliding strips are arc-shaped and slidably connected to the two sliding grooves respectively.

[0009] Preferably, the adjusting mechanism includes: a connecting shaft, the two ends of which are movably connected to the base via bearings; drive gears fixed to the two ends of the connecting shaft; and adjusting gears fixedly connected to the outside of the two sleeves, wherein the two adjusting gears mesh with the two drive gears respectively, and the drive gears form a transmission rotation cutting position changing structure with the sleeves through the adjusting gears and the fixing ring; the adjusting mechanism further includes: a drive structure for driving the rotation of the connecting shaft.

[0010] Preferably, the drive structure includes: a servo motor fixedly connected to the front side of the base, the servo motor and the connecting shaft being located at the same cross section; pulleys respectively located at the output end of the servo motor and the outer side of the center of the connecting shaft, and a transmission belt sleeved between the two pulleys.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a limiting mechanism to insert a columnar steel into the inside of a sleeve and extend it from one end of another sleeve, aligning the marked cutting position with the cutting machine. Then, an air pump is activated to continue inflating the clamping airbag through a connecting pipe and an annular pipe. The clamping air pump expands sequentially, squeezing and clamping the columnar steel inside the sleeve, thus initiating the cutting process. As the sleeve rotates, the annular pipe's compression extends or contracts in its direction, facilitating the fixed cutting of columnar steel of different diameters. This increases the friction of the equipment's steel structure, ensuring stability during cutting and reducing vibrations that could cause the cutting position to shift.

[0013] This invention utilizes an adjustment mechanism that employs a servo motor to drive the connecting shaft via a pulley and transmission belt, causing it to rotate in the direction of the servo motor's output. Simultaneously, the connecting shaft drives two drive gears to rotate, which in turn drives the adjusting gear to rotate the sleeve. Furthermore, the fixing ring rotates along with the sleeve, and simultaneously rotates on the surface of the slide bar via a sliding groove. This causes the annular tube to compress and contract, thereby ensuring that the cutting position does not shift due to adjustments to the columnar steel when making annular cutting marks or creating annular grooves on the surface of the columnar steel, thus improving the flexibility of the equipment.

The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] Please see Figures 1 to 4The present invention preferably provides the following technical solution: a cutting device for steel structure processing, comprising: a base 1; a cutting machine 2 disposed on the base 1, wherein the cutting machine 2 is movably connected to the middle position of the rear end of the base 1 via a torque spring and a rotating shaft, and is used for cutting steel structures; a limiting mechanism 3 disposed on the surface of the base 1, used for limiting and clamping the columnar steel 4 to prevent the equipment from vibrating and displacing during cutting or annular grooving, thereby causing the cutting line to deviate; the limiting mechanism 3 includes a transmission support, symmetrically mounted on the transmission support and rotatable. Two movable sleeves 301 are fixedly installed with a fixing ring 302 at the end of each sleeve 301; a plurality of clamping airbags 303 are evenly embedded inside each sleeve 301, wherein each clamping airbag 303 is annular, and the clamping airbags 303 located inside the same sleeve 301 are interconnected through air pipes to increase the friction with the columnar steel 4 and ensure its clamping stability; an air supply structure is installed on the base 1 for inflating and deflating the clamping airbags 303, thereby facilitating the control of clamping and releasing the columnar steel 4, reducing resonance during cutting to a certain extent and affecting clamping stability.

[0022] Example 2

[0023] Please see Figures 1 to 3 The present invention preferably provides the following technical solution: the gas supply structure includes:

[0024] A connecting pipe 305 and an air pump 306 are installed at the lower part of the base 1, wherein one end of the connecting pipe is connected to the output end of the air pump 306; and an annular pipe 304 is respectively wrapped around the outside of the two sleeves 301, with one end of the annular pipe 304 communicating with the connecting pipe 305, and the other end passing through the corresponding sleeve 301 and communicating with one of the clamping airbags 303. When the air pump 306 is running, it is used to inflate and deflate several clamping airbags 303. The columnar steel 4 is inserted into the interior of the sleeve 301 and from the other sleeve 301... One end extends out, aligning the marked cutting position with the cutting machine 2. Then, the air pump 306 is started, and the clamping airbag 303 is continuously inflated through the connecting pipe 305 and the annular pipe 304. At this time, the clamping air pump 306 expands in sequence to squeeze and clamp the columnar steel 4 inside the sleeve, and then cutting is performed. When the sleeve rotates, the annular pipe 304 squeezes and extends or contracts in its direction, which is beneficial for fixing and cutting columnar steel 4 of different diameters, increasing the friction of the steel structure of the equipment, ensuring the stability during cutting, and reducing the vibration caused by cutting, which may cause the cutting position to shift.

[0025] The annular tube 304 is a compressible foldable tube, which ensures that when the sleeve 301 rotates, it can stretch or contract along its trajectory, thus avoiding obstructing the movement trajectory of the sleeve 301.

[0026] The transmission support includes: sliding grooves 6 respectively opened on the opposite sides of the two fixed rings 302, each sliding groove 6 having a concave cross-section; a set of left-right symmetrical fixing bars 7 fixed on the upper surface of the base 1; and two sliding bars 8 provided on opposite sides of the two fixed bars 7, both of which are arc-shaped and slidably connected to the two sliding grooves 6 respectively. The sliding bars drive the sleeve 301 to rotate smoothly through the fixed rings 302, and the fixing bars 7 can stably support the limiting mechanism 3.

[0027] Example 3

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention preferably provides the following technical solution: the adjusting mechanism 5 includes: a connecting shaft 504, the two ends of which are movably connected to the base 1 via bearings; drive gears 505 fixed at both ends of the connecting shaft 504; and adjusting gears 506 fixedly connected to the outside of the two sleeves 301, wherein the two adjusting gears 506 mesh with the two drive gears 505 respectively, and the drive gears 505 form a transmission rotation cutting position changing structure with the sleeves 301 through the adjusting gears 506 and the fixing ring 302; The adjustment mechanism 5 also includes a drive structure for driving the rotation of the connecting shaft 504. The connecting shaft 504 drives two drive gears 505 to rotate and simultaneously drives the adjustment gear 506 to drive the sleeve 301 to rotate. Next, the fixing ring 302 follows the rotation of the sleeve 301. At the same time, the fixing ring 302 rotates on the surface of the slide bar through the slide groove 6. The annular tube 304 is squeezed and contracted, which helps to ensure that the cutting position will not shift due to the adjustment of the columnar steel 4 when making annular cutting marks or opening annular grooves on the surface of the columnar steel 4, thereby improving the flexibility of equipment use.

[0029] The driving structure includes: a servo motor 501 fixedly connected to the front side of the base 1, wherein the servo motor 501 and the connecting shaft 504 are located at the same cross section; pulleys 502 respectively located at the output end of the servo motor 501 and the outer side of the center of the connecting shaft 504; a transmission belt 503 is sleeved between the two pulleys 502; the servo motor 501 drives the connecting shaft 504 through the pulleys 502 and the transmission belt 503, so that it rotates in the same direction as the output end of the servo motor 501, which is beneficial to drive the two sleeves 301 to rotate in the same direction and along the same trajectory at the same time, so that the rotation speed of the two ends of the columnar steel 4 is uniform, and the cutting operation is avoided.

[0030] Based on the above embodiments 1, 2, and 3, the working principle is further described; in use, the columnar steel 4 is inserted into the inside of the sleeve 301 and extends from one end of the other sleeve 301, aligning its marked cutting position with the cutting machine 2. Then, the air pump 306 is started to continue inflating the clamping airbag 303 through the connecting pipe 305 and the annular pipe 304. At this time, the clamping air pump 306 expands sequentially, squeezing and clamping the columnar steel 4 inside the sleeve, and then cutting is performed. When the sleeve rotates, the annular pipe 304 compresses and extends along its direction... When the columnar steel 4 needs to be cut into a ring shape, the servo motor 501 is started to drive the connecting shaft 504 through the pulley 502 and the transmission belt 503, so that it rotates in the same direction as the output of the servo motor 501. At the same time, the connecting shaft 504 drives the two drive gears 505 to rotate and drives the adjusting gear 506 to rotate the sleeve 301. Then, the fixing ring 302 rotates with the sleeve 301. At the same time, the fixing ring 302 rotates on the surface of the slide bar through the slide groove 6, and the annular tube 304 is squeezed and contracted.
