Description

Technical Field

[0001] The present application relates to the technical field of cutting equipment, and in particular to a flat steel cutting and positioning device. Background Art

[0002] Flat steel is a kind of steel with a rectangular cross section and slightly blunt edges. As finished products, flat steel can be used to make hoops, tools and mechanical parts, and can be used as frame components and escalators in construction.

[0003] A flat steel cutting device is disclosed in the patent with the announcement number CN220427537U. In the device, since the original length of the flat steel is relatively long, a cutting device is required to cut the relatively long flat steel into flat steels of different lengths. When the device is used to cut the flat steel, it is inconvenient to control the cutting length of the flat steel. Utility Model Content

[0004] The purpose of this application is to propose a flat steel cutting and positioning device in view of the above-mentioned problems existing in the prior art.

[0005] The present application can be implemented through the following technical scheme: a flat steel cutting positioning device, including a fixed frame, a slide groove is provided on the fixed frame, the slide groove is slidably connected to a positioning block, the positioning block can contact one end of the flat steel in the length direction to limit the flat steel, and the positioning block is fixed to the fixed frame through a fixing component.

[0006] In the above technical solution, by setting a positioning block that can contact one end of the flat steel in the length direction, the positioning block can limit the position of the flat steel so that the flat steel extends accurately relative to the cutting tool, so that the length of the flat steel after cutting is accurate.

[0007] Furthermore, the fixing assembly includes a lead screw threadedly connected to the positioning block, and a motor driving the lead screw to rotate, and the length direction of the lead screw is consistent with the length direction of the slide slot.

[0008] In the above technical solution, the motor can drive the lead screw to rotate, and when the positioning block moves to the desired position, the motor can be controlled to stop driving the lead screw to rotate, and the positioning block is fixed relative to the fixing frame.

[0009] Furthermore, it also includes a laser ranging sensor, which is used to detect the horizontal distance from the cutting tool to the positioning block. The motor is electrically connected to a controller, and the controller is electrically connected to the laser ranging sensor so that when the horizontal distance from the positioning block to the cutting tool is a set distance, the motor can stop driving the screw to rotate.

[0010] In the above technical solution, the cutting length of the flat steel can be pre-set. When the motor drives the lead screw to rotate, the laser ranging sensor can measure the horizontal distance from the cutting tool to the positioning block. When the horizontal distance from the cutting tool to the positioning block is the set distance, the distance is the length that the flat steel needs to extend relative to the cutting tool. The laser ranging sensor can feedback the signal to the controller, and the controller can stop the lead screw through the motor.

[0011] Furthermore, it also includes a positioning assembly for making the positioning block face the cutting tool, and the bottom of the fixing frame is rotatably connected with a brake universal wheel that can contact the ground.

[0012] In the above technical solution, the positioning assembly can make the positioning block face the cutting tool so that the length direction of the slide slot is consistent with the length direction of the flat steel placed on the cutting equipment, and the brake universal wheel facilitates the movement of the fixing frame.

[0013] Furthermore, the positioning assembly includes a telescopic rod and an abutment plate. The telescopic rod is fixedly mounted on the vertical side wall of the fixing frame, and the length direction of the telescopic rod is consistent with the length direction of the slide slot; and the abutment plate is used to abut against the outer wall of the cutting device.

[0014] In the above technical solution, the abutment plate is first abutted against the vertical side wall of the cutting device, the length direction of the slide groove is perpendicular to the length direction of the cutting tool, and the fixed frame can be directly opposite the cutting tool. In the process of pulling the fixed frame along the length direction of the telescopic rod, the fixed frame can move linearly along the length direction of the telescopic rod, further expanding the moving range of the positioning block, and in this process, the length direction of the slide groove is always consistent with the length direction of the flat steel placed on the cutting device.

[0015] Furthermore, the abutment plate can be fixed to the cutting device by screws.

[0016] In the above technical solution, the abutment plate can be fixed to the cutting device by screws, and there is no need to hold the abutment plate by hand to keep the abutment plate in abutment with the vertical side wall of the cutting device, which is more convenient.

[0017] Furthermore, the laser distance measuring sensor is located in a box body, the box body is fixedly mounted on the positioning block, and the box body is hinged with a cover plate, and the cover plate is opened so that the laser distance measuring sensor can send laser to the cutting tool.

[0018] In the above technical solution, the box body and the cover plate can protect the laser ranging sensor, reduce the possibility of debris and coolant splashing onto the laser ranging sensor during cutting, and reduce the possibility of damage to the laser ranging sensor.

[0019] Furthermore, a plurality of heat dissipation holes are formed through the side wall of the box body away from the cover plate, and the laser ranging sensor is spaced apart from the inner wall of the box body.

[0020] In the above technical solution, the laser ranging sensor itself generates a lot of heat when working. The heat dissipation holes facilitate the heat dissipation of the laser ranging sensor to extend its service life. The laser ranging sensor is spaced apart from the inner wall of the box body to prevent the box body and the laser ranging sensor from fitting closely and affecting its own heat dissipation.

[0021] To sum up, the present application has the following technical effects: by setting a positioning block that can contact one end of the flat steel in the length direction, the positioning block can limit the position of the flat steel, so that when the flat steel is fixed on the cutting equipment, each time the flat steel is pushed, the flat steel extends the same distance relative to the cutting tool, so that the length of the flat steel after cutting is accurate.

[0027] Embodiment 1:

[0028] Please refer to the figures attached to the specification. An embodiment of the present application provides a flat steel cutting and positioning device, including a fixed frame 1, which is used to be placed on the opposite side of a cutting device 5. The cutting device 5 in this embodiment is a sawing machine, and the cutting device 5 has a cutting tool 51, and the cutting tool 51 is a saw blade. The fixed frame 1 can be fixed relative to the ground. The fixed frame 1 has a slide groove 11 along its own length direction. The slide groove 11 is slidably connected to a positioning block 2. The positioning block 2 can slide along the length direction of the slide groove 11 to adjust its horizontal distance relative to the cutting tool 51. The cutting device 5 is provided with a clamp that can fix the flat steel. The length direction of the slide groove 11 is consistent with the length direction of the flat steel when it is fixed on the cutting device 5. The positioning block 2 can contact one end of the length direction of the flat steel to limit the flat steel, so that the length of the flat steel relative to the cutting tool 51 is accurate, thereby making the cutting length of the flat steel accurate.

[0029] Please refer to the figure attached to the specification, the positioning block 2 can be fixed to the fixing frame 1 through a fixing assembly 3, and the fixing assembly 3 includes a lead screw 31 threadedly connected to the positioning block 2, and a motor 32 driving the lead screw 31 to rotate, and the length direction of the lead screw 31 is consistent with the length direction of the slide 11. The motor 32 can drive the lead screw 31 to rotate forward or reverse to make the positioning block 2 close to or away from the cutting device 5.

[0030] The working principle of this embodiment is: the motor 32 can drive the screw 31 to rotate, so that the rotation of the screw 31 can drive the positioning block 2 to move linearly along the slide groove 11, so that the horizontal distance of the positioning block 2 relative to the cutting tool can be changed, so that the positioning block 2 can adapt to the cutting requirements of different lengths of flat steel.

[0031] Embodiment 2:

[0032] Please refer to the figures attached to the specification. The structure and principle of this embodiment are basically the same as those of the first embodiment. The difference is that a box body 12 is fixedly installed at one end of the positioning block 2 away from the fixing frame 1. The box body 12 is hinged with a cover plate 13. The opening of the box body 12 faces the cutting tool 51. A laser distance sensor 4 is installed in the box body 12. When the cutting device 5 is in a shutdown state, the cutting tool 51 is located above the flat steel placed on the cutting device 5. The laser distance sensor 4 can send a laser to the cutting tool 51 at this time. The laser distance sensor 4 is used to detect the horizontal distance from the positioning block 2 to the cutting tool 51, and a controller 7 is electrically connected to the motor 32. The controller 7 is electrically connected to the laser distance sensor 4. When used, the required cutting length of the flat steel can be pre-set, and then the laser distance sensor 4 can measure the horizontal distance from the positioning block 2 to the cutting tool 51, thereby feeding back a signal to the controller 7 to control the motor 32 to rotate forward or reverse so that the horizontal distance from the positioning block 2 to the cutting tool 51 is equal to the required cutting length of the flat steel. When the cover plate 13 is open, the laser distance sensor 4 can send laser to the cutting tool 51, and when the cover plate 13 is closed, the laser distance sensor 4 cannot send laser to the cutting tool 51. By setting the box body 12, it is possible to prevent the coolant or cutting waste from splashing onto the laser distance sensor 4 when the cutting equipment 5 cuts the flat steel, thereby damaging the laser distance sensor 4. Among them, a plurality of heat dissipation holes 121 are provided through the side wall of the box body 12 away from the cover plate 13, and the laser distance sensor 4 is spaced apart from the inner wall of the box body 12 to prevent the laser distance sensor 4 from being too tightly attached to the inner wall of the box body 12 and affecting its own heat dissipation. The heat dissipation holes 121 can facilitate the heat dissipation of the laser distance sensor 4. A cooling water pipe can be laid in the box body 12, and cold water is passed through the cooling water pipe to further improve the cooling effect of the laser distance sensor 4.

[0033] Please refer to the figure of the attached drawings of the specification. The positioning block 2 is directly opposite to the cutting tool 51 through a positioning assembly 8, so that the length direction of the slide 11 is consistent with the length direction of the flat steel fixed on the cutting device 5. The positioning assembly 8 includes a telescopic rod 81 installed on the vertical side wall of the fixed frame 1. The length direction of the telescopic rod 81 is consistent with the length direction of the slide 11. The fixed end of the telescopic rod 81 is fixedly installed on the vertical side wall of the fixed frame 1. The telescopic end of the telescopic rod 81 is fixedly installed with an abutment plate 82, and the abutment plate 82 can contact the vertical side wall of the cutting device 5. Among them, the abutment plate 82 can be installed on the vertical side wall of the cutting device 5 by screws 10, and the bottom of the fixed frame 1 is rotatably connected with a brake universal wheel 9 that can contact the ground. When in use, first move the fixed frame 1 to the opposite side of the cutting device 5, and then fix the abutment plate 82 on the vertical side wall of the cutting device 5 by screws 10. At this time, the length direction of the slide 11 is consistent with the length direction of the flat steel located on the cutting device 5.

[0034] The working principle of this embodiment is as follows: first, the fixing frame 1 is moved to the opposite side of the cutting device 5, and then the abutment plate 82 is fixed to the vertical side wall of the cutting device 5 by means of screws 10, at which point the length direction of the slide slot 11 is consistent with the length direction of the flat steel on the cutting device 5. Then, the cutting length of the flat steel is set, and then the controller 7 can drive the lead screw 31 to rotate through the motor 32, and when the horizontal distance from the positioning block 2 to the cutting tool 51 reaches the set length, the motor 32 can stop driving the lead screw 31 to rotate, and at this point, the positioning block 2 is fixed relative to the fixing frame 1.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
