Description

Technical Field

[0001] This invention relates to the field of cutting machine technology, and in particular to a channel steel cutting device. Background Technology

[0002] Channel steel is widely used in civil engineering construction. Usually, construction sites purchase channel steel of standard length (usually 3 meters). After being transported to the site, the channel steel is cut into the required length using a cutting machine according to actual needs.

[0003] The cutting machines used on construction sites are usually simple cutting machines (such as the Chinese utility model patent with application number CN201420043933.4). When cutting, the cutting position is first marked on the channel steel with a marker, then the channel steel is placed on the worktable of the cutting machine. Then the worker presses down on the channel steel with one hand and holds the handle of the cutting machine with the other, aligns the blade with the marked cutting position, and then cuts.

[0004] However, due to the large length of the channel steel and the strong vibration generated during cutting, it is difficult to keep the channel steel stationary with just one hand. The channel steel will shift, resulting in an uneven cut surface. At the same time, there is a large error in directly aligning the blade with the marked cutting position by visual inspection. Summary of the Invention

[0005] In view of this, it is necessary to provide a channel steel cutting device to solve the technical problem that when a single person cuts channel steel with a simple cutting machine, the channel steel is prone to displacement, resulting in an uneven cutting surface and a large cutting position error.

[0006] To achieve the above objectives, the present invention provides a channel steel cutting device, including an operating table, a cutting mechanism, an adjustment mechanism, and an identification mechanism;

[0007] The cutting mechanism includes a cutting bracket, a slice, and a cutting drive. The cutting bracket is hinged to the operating table, the slice is rotatably mounted on the cutting bracket, and the cutting drive is connected to the slice and used to drive the slice to rotate.

[0008] The adjustment mechanism includes a base, a lateral position adjustment component, a translation rod, two clamping components, and two double-headed cylinders. The base is fixedly connected to the operating table. The fixed end of the lateral position adjustment component is fixed to the base. The movable end of the lateral position adjustment component is fixedly connected to the translation rod. The fixed ends of the two clamping components are both fixed to the translation rod. The movable ends of the two clamping components are respectively fixedly connected to the fixed ends of the two double-headed cylinders and are used to drive the double-headed cylinders to move up and down. The two output shafts of the double-headed cylinders are horizontally arranged and are respectively used to abut against the opposite side walls of the channel steel.

[0009] The identification mechanism includes a camera, the central axis of which is coplanar with the slice, and the camera is used to photograph the outer wall of the channel steel above the operating table.

[0010] In some embodiments, the lateral position adjusting component includes two upright plates, a lead screw, a rotation drive, a nut, a slide rod, and a bushing. Both upright plates are fixed to the base. The two ends of the lead screw are rotatably connected to the two upright plates respectively. The rotation drive is connected to the lead screw and used to drive the lead screw to rotate. The nut is threaded onto the lead screw. The two ends of the slide rod are fixed to the two upright plates respectively, and the slide rod is parallel to the lead screw. The bushing is slidably fitted onto the slide rod and is fixedly connected to the nut. The nut is fixedly connected to the translation rod.

[0011] In some embodiments, the rotation drive is a rotary motor, and the output shaft of the rotary motor is coaxially and fixedly connected to the lead screw.

[0012] In some embodiments, the lateral position adjustment member further includes a fixing plate, which is fixed to one of the vertical plates, and the housing of the rotating motor is fixed to the fixing plate.

[0013] In some embodiments, the bushing and the nut are fixedly connected via a first connecting rod.

[0014] In some embodiments, the nut is fixedly connected to the translation rod via a second link.

[0015] In some embodiments, a rubber sleeve is fitted onto the end of the output shaft of the dual-head cylinder.

[0016] In some embodiments, the operating table is provided with a plurality of fixing holes.

[0017] In some embodiments, the cutting mechanism further includes an elastic element, one end of which is connected to the operating table and the other end of which is connected to the cutting bracket.

[0018] In some embodiments, the identification mechanism further includes a placement platform fixed to the base, and the camera is mounted on the placement platform.

[0019] Compared with the prior art, the beneficial effects of the technical solution proposed in this invention are as follows: the output shafts of two double-headed cylinders abut against the two inner sidewalls of the channel steel, thereby fixing the channel steel to the double-headed cylinders and making the channel steel perpendicular to the slice. The double-headed cylinders are pressed by the clamping component, thereby pressing the channel steel against the operating table to prevent displacement during cutting and improve the flatness of the cutting surface. The outer sidewall of the channel steel above the operating table is photographed by the camera, thereby detecting the marked position. In conjunction with the lateral position adjustment component, the marked position can be automatically aligned with the slice, which greatly improves the accuracy of the cutting position. At the same time, this device only requires one person to operate, is easy to use, and greatly improves work efficiency. Attached Figure Description

Detailed Implementation

[0026] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0027] Please refer to Figures 1-3 The present invention provides a channel steel cutting device, including an operating table 1, a cutting mechanism 2, an adjustment mechanism 3 and an identification mechanism 4.

[0028] The cutting mechanism 2 includes a cutting bracket 21, a slice 22, and a cutting drive 23. The cutting bracket 21 is hinged to the operating table 1. The slice 22 is rotatably mounted on the cutting bracket 21. The cutting drive 23 is connected to the slice 22 and is used to drive the slice 22 to rotate.

[0029] The adjustment mechanism 3 includes a base 31, a lateral position adjusting component 32, a translation rod 33, two clamping components 34, and two double-headed cylinders 35. The base 31 is fixedly connected to the operating table 1. The fixed end of the lateral position adjusting component 32 is fixed to the base 31, and the movable end of the lateral position adjusting component 32 is fixedly connected to the translation rod 33. The fixed ends of the two clamping components 34 are both fixed to the translation rod 33, and the movable ends of the two clamping components 34 are respectively fixedly connected to the fixed ends of the two double-headed cylinders 35, and are used to drive the double-headed cylinders 35 to move up and down. The two output shafts of the double-headed cylinders 35 are horizontally arranged and are respectively used to abut against the opposite side walls of the channel steel 5, thereby fixing the double-headed cylinders 35 to the channel steel 5 so as to drive the translation rod 33 to move laterally through the lateral position adjusting component 32. In this embodiment, the clamping component 34 is a clamping cylinder, and the cylinder body of the clamping cylinder is fixedly connected to the translation rod 33 through a crossbar 341.

[0030] The identification mechanism 4 includes a camera 41, the central axis of which is coplanar with the slice 22, and the camera 41 is used to photograph the outer wall of the channel steel 5 above the operating table 1.

[0031] In use, the operating table 1 is fixed to the ground. Then, the cutting position is marked on the channel steel 5 using a marker. The channel steel 5 is then placed on the operating table 1 with its open end facing upwards, ensuring the marked cutting position is roughly aligned with the slice 22. Next, the clamping component 34 drives the double-headed cylinders 35 downwards, causing both cylinders 35 to enter between the two inner walls of the channel steel 5. The output shafts of the two cylinders 35 are then extended outwards until they abut against the inner wall of the channel steel 5. At this point, the channel steel 5 is perpendicular to the slice 22. Finally, the lateral position adjustment component 32... The drive translation rod 33 moves laterally, thereby causing the double-headed cylinder 35 and the channel steel 5 to translate. During the translation process, the camera 41 captures the outer wall of the channel steel 5 above the operating table 1. When the center of the image captured by the camera 41 detects the mark of the cutting position, the translation stops. Then, the clamping member 34 further clamps the channel steel 5. At this time, the channel steel 5 is clamped on the operating table 1, and the mark position is aligned with the slice 22. By manually gripping the cutting bracket 21 and pressing it down, the rotating slice 22 comes into contact with the channel steel 5, thereby achieving the cutting of the channel steel 5.

[0032] This invention uses the output shafts of two double-headed cylinders 35 to abut against the two inner walls of the channel steel 5, thereby fixing the channel steel 5 to the double-headed cylinders 35 and making the channel steel 5 perpendicular to the slice 22. The double-headed cylinders 35 are pressed by the clamping member 34, thereby pressing the channel steel 4 against the operating table 1 to prevent displacement during cutting and improve the flatness of the cut surface. The outer wall of the channel steel 5 above the operating table 1 is photographed by the camera 41, thereby detecting the marked position. In conjunction with the lateral position adjustment member 32, the marked position can be automatically aligned with the slice 22, which greatly improves the accuracy of the cutting position. At the same time, this device only requires one person to operate, is easy to use, and greatly improves work efficiency.

[0033] To understand the specific function of the lateral position adjustment component 32, please refer to... Figure 3 and Figure 4 In a preferred embodiment, the lateral position adjusting member 32 includes two upright plates 321, a lead screw 322, a rotation drive member 323, a nut 324, a slide rod 325, and a bushing 326. Both upright plates 321 are fixed to the base 31. The two ends of the lead screw 322 are rotatably connected to the two upright plates 321 respectively. The rotation drive member 323 is connected to the lead screw 322 and is used to drive the lead screw 322 to rotate. The nut 324 is threaded onto the lead screw 322. The two ends of the slide rod 325 are fixed to the two upright plates 321 respectively. On the upright plate 321, the slide rod 325 is parallel to the lead rod 322. The bushing 326 is slidably sleeved on the slide rod 325. The bushing 326 is fixedly connected to the nut 324. The nut 324 is fixedly connected to the translation rod 33. In use, the rotation drive 323 drives the lead rod 322 to rotate. When the lead rod 322 rotates, it acts on the nut 324. Since the nut 324 cannot rotate due to the action of the bushing 326, the rotation of the lead rod 322 is converted into the movement of the nut 324. The nut 324 drives the translation rod 33 to translate.

[0034] To understand the specific functions of the rotation drive component 323, please refer to [reference needed]. Figure 3 and Figure 4 In a preferred embodiment, the rotation drive 323 is a rotary motor, and the output shaft of the rotary motor is coaxially and fixedly connected to the lead screw 322.

[0035] For specific instructions on installing the rotating motor, please refer to... Figure 3 and Figure 4 In a preferred embodiment, the lateral position adjustment member 32 further includes a fixing plate 327, which is fixed to one of the upright plates 321, and the housing of the rotating motor is fixed to the fixing plate 327.

[0036] To specifically achieve the fixed connection between the bushing 326 and the nut 324, please refer to... Figure 3 and Figure 4 In a preferred embodiment, the bushing 326 and the nut 324 are fixedly connected via a first connecting rod 328.

[0037] To specifically achieve the fixed connection between the nut 324 and the translation rod 33, please refer to... Figure 3 and Figure 4 In a preferred embodiment, the nut 324 is fixedly connected to the translation rod 33 via a second connecting rod 329.

[0038] To increase the friction between the output shaft of the double-ended cylinder 35 and the inner wall of the channel steel 5, please refer to... Figure 3 and Figure 5 In a preferred embodiment, a rubber sleeve 36 is fitted onto the end of the output shaft of the dual-head cylinder 35.

[0039] To facilitate fixing the control panel 1 to the ground, please refer to... Figure 2 In a preferred embodiment, the operating table 1 is provided with a plurality of fixing holes 11. In use, the operating table 1 is fixed by passing anchor bolts through the fixing holes 11 to prevent the operating table 1 from tipping over due to the excessive weight of the channel steel 5 placed on it.

[0040] To ensure the cutting bracket 21 remains in the supported position, please refer to... Figure 1 and Figure 2 In a preferred embodiment, the cutting mechanism 2 further includes an elastic element, one end of which is connected to the operating table, and the other end of which is connected to the cutting bracket 21.

[0041] For specific instructions on installing camera 41, please refer to... Figure 1 and Figure 2 In a preferred embodiment, the identification mechanism 4 further includes a placement platform 42, which is fixed to the base 31, and the camera 41 is mounted on the placement platform 42.

[0042] In this embodiment, the specific principle of the recognition mechanism 4 is as follows: the image captured by the camera 41 is first converted into a grayscale image, then the pixel values ​​of the top row of pixels in the grayscale image are obtained, and the pixel value abrupt changes are filtered out from them. Then the pixel values ​​of the second row of pixels are obtained, and the pixel value abrupt changes are filtered out. Then the pixels of the next row are obtained until all rows have been traversed. In this way, several pixel value abrupt changes can be obtained. The average value of the horizontal coordinates of these pixel value abrupt changes is taken as the horizontal coordinate of the cutting line, thereby realizing the function of the recognition mechanism 4.

[0043] To better understand this invention, the following is combined with... Figures 1-5The working process of the channel steel cutting device provided by the present invention will be described in detail below: In use, the operating table 1 is fixed to the ground. Then, the cutting position is marked on the channel steel 5 using a marker. The channel steel 5 is then placed on the operating table 1 with its open end facing upwards, so that the marked cutting position is approximately aligned with the slice 22. Then, the double-headed cylinders 35 are driven downwards by the clamping member 34, causing both double-headed cylinders 35 to enter between the two inner sidewalls of the channel steel 5. The output shafts of the two double-headed cylinders 35 are then extended outwards until they abut against the inner sidewall of the channel steel 5. At this point, the channel steel 5 is perpendicular to the slice 22. Then, the translation rod 33 is driven to move laterally by the lateral position adjustment component 32, thereby causing the double-headed cylinder 35 and the channel steel 5 to move laterally. During the translation process, the outer wall of the channel steel 5 above the operating table 1 is photographed by the camera 41. When the center of the image captured by the camera 41 detects the mark of the cutting position, the translation stops. Then, the channel steel 5 is further pressed by the clamping component 34. At this time, the channel steel 5 is pressed on the operating table 1, and the mark position is aligned with the slice 22. By manually gripping the cutting bracket 21 and pressing it down, the rotating slice 22 comes into contact with the channel steel 5, thereby realizing the cutting of the channel steel 5.

[0044] This invention uses the output shafts of two double-headed cylinders 35 to abut against the two inner walls of the channel steel 5, thereby fixing the channel steel 5 to the double-headed cylinders 35 and making the channel steel 5 perpendicular to the slice 22. The double-headed cylinders 35 are pressed by the clamping member 34, thereby pressing the channel steel 4 against the operating table 1 to prevent displacement during cutting and improve the flatness of the cut surface. The outer wall of the channel steel 5 above the operating table 1 is photographed by the camera 41, thereby detecting the marked position. In conjunction with the lateral position adjustment member 32, the marked position can be automatically aligned with the slice 22, which greatly improves the accuracy of the cutting position. At the same time, this device only requires one person to operate, is easy to use, and greatly improves work efficiency.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
