Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a profile cutting device for prefabricated building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, and decoration construction. The place where construction work is carried out is called the "construction site" or "construction site". Profile cutting equipment is needed in construction.

[0003] In prefabricated building construction, the ability of profile cutting equipment to fix workpieces directly affects cutting accuracy and efficiency. When the equipment is only equipped with a single-specification clamp, when faced with profiles of different cross-sectional dimensions (such as 80mm×80mm square steel and 40mm×60mm rectangular tube), operators have to frequently change clamps or manually add shims to compensate for gaps. This adaptation process not only interrupts continuous operation, but may also lead to uneven distribution of clamping force—smaller profiles are prone to displacement, while larger profiles may deform due to local pressure. When processing multiple specifications of profiles in batches, repeated clamp adjustments will significantly prolong preparation time and disrupt the production rhythm.

[0004] To address the aforementioned issues, we have made improvements and proposed a profile cutting device for prefabricated building construction. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a profile cutting device for prefabricated building construction, including a base plate, a cutting box fixedly connected to the top of the base plate, a first turntable movably connected to the left side of the inner cavity of the cutting box, a second turntable movably connected to the right side of the inner cavity of the cutting box, an adjustment box fixedly connected to the inner side of both the first and second turntables, a positive and negative screw rod movably connected to the inner cavity of the adjustment box through a bearing, threaded sleeves threaded to the top and bottom of the surface of the positive and negative screw rods, a clamping plate fixedly connected to the inner side of the threaded sleeve, and an anti-slip pad fixedly connected to the inner side of the clamping plate.

[0006] Preferably, a stepper motor for driving the first turntable to rotate is fixedly connected to the left side of the cutting box. The output end of the stepper motor extends into the inner cavity of the cutting box and is fixedly connected to the middle of the left side of the first turntable. A servo motor for driving the forward and reverse screws to rotate is fixedly connected to the top of the adjustment box. The output end of the servo motor is fixedly connected to the top of the forward and reverse screws.

[0007] Preferably, a longitudinal sliding groove is provided on the outer side of the inner wall of the regulating box, a slider is fixedly connected to the outer side of the screw sleeve, the outer side of the slider is slidably connected to the inner cavity of the longitudinal sliding groove, a guide groove is provided through the inner side of the regulating box, and the inner side of the clamp plate extends through the inner cavity of the guide groove and extends to the inner side of the regulating box.

[0008] Preferably, annular grooves are provided on both the left and right sides of the inner wall of the cutting box, and sliding columns are fixedly connected to the top and bottom of the outer sides of the first turntable and the second turntable, with the outer sides of the sliding columns slidably connected to the inner cavity of the annular grooves.

[0009] Preferably, a laser cutting assembly is provided at the top of the inner wall of the cutting box, and a flow guide baffle is fixedly connected to the bottom of the inner cavity of the cutting box.

[0010] Preferably, a bracket is fixedly connected to the bottom of both the left and right sides of the inner wall of the cutting box, a filter screen is clamped in the inner cavity of the bracket, a duct fan is fixedly connected to the middle of the bottom of the inner cavity of the cutting box, the output end of the duct fan extends through to the right side of the cutting box, and a ventilation mesh is embedded in the top of the right side of the cutting box.

[0011] Compared with the prior art, this utility model provides a profile cutting device for prefabricated building construction, which has the following advantages:

[0012] 1. This profile cutting device for prefabricated building construction uses a servo motor to drive a pair of screws to rotate. The screws, with their symmetrical threads, move the two screw sleeves inward simultaneously. The screw sleeves then move the clamping plate inward, bringing the inner side of the anti-slip pad into contact with the outer side of the workpiece. This allows for the fixing of workpieces of different specifications, facilitating compatibility with various sizes and preventing offset caused by unilateral force. The device also uses a stepper motor to drive the first turntable to rotate. The first turntable, through the transmission of the adjustment box, drives the workpiece to rotate, facilitating automatic workpiece rotation, significantly reducing manual intervention, and ensuring consistent cutting surfaces. It is particularly suitable for the efficient and continuous processing of irregular profiles in prefabricated buildings, balancing positioning accuracy and ease of operation.

[0013] 2. This profile cutting device for prefabricated building construction effectively improves the smoothness of the rotation of the first and second turntables by setting sliding columns and annular sliding grooves. It also effectively improves the stability of the threaded sleeve during its up-and-down movement by setting longitudinal sliding grooves and sliders. The suction generated by the input end of the exhaust fan draws air mixed with dust and debris downwards, and the dust and debris are trapped by the filter screen, which facilitates the collection and retention of dust and debris and avoids the direct discharge of dust and debris, which would have an adverse impact on the surrounding environment. The filter screen can be disassembled for cleaning or replacement by setting a retainer. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4A profile cutting device for prefabricated building construction includes a base plate 1. A cutting box 2 is fixedly connected to the top of the base plate 1. A first turntable 5 is movably connected to the left side of the inner cavity of the cutting box 2, and a second turntable 6 is movably connected to the right side of the inner cavity of the cutting box 2. An adjusting box 7 is fixedly connected to the inner side of both the first turntable 5 and the second turntable 6. A positive and negative screw 16 is movably connected to the inner cavity of the adjusting box 7 via bearings. A screw sleeve 17 is threadedly connected to the top and bottom of the surface of the positive and negative screw 16. A clamping plate 18 is fixedly connected to the inner side of the screw sleeve 17, and an anti-slip pad 19 is fixedly connected to the inner side of the clamping plate 18. A stepper motor 3 for driving the first turntable 5 to rotate is fixedly connected to the left side of the cutting box 2. The output end of the stepper motor 3 extends through the inner cavity of the cutting box 2, and the output end of the stepper motor 3 is fixed. A servo motor 15 for driving the rotation of the positive and negative screws 16 is fixedly connected to the middle of the left side of the first turntable 5. The output end of the servo motor 15 is fixedly connected to the top of the positive and negative screws 16. A longitudinal groove 20 is opened on the outer side of the inner wall of the adjustment box 7. A slider 21 is fixedly connected to the outer side of the screw sleeve 17. The outer side of the slider 21 is slidably connected to the inner cavity of the longitudinal groove 20. A guide groove 22 is opened through the inner side of the adjustment box 7. The inner side of the clamping plate 18 is opened through the inner cavity of the guide groove 22 and extends to the inner side of the adjustment box 7. Annular grooves 13 are opened on both the left and right sides of the inner wall of the cutting box 2. Sliding columns 14 are fixedly connected to the top and bottom of the outer sides of the first turntable 5 and the second turntable 6. The outer side of the sliding column 14 is slidably connected to the inner cavity of the annular groove 13.

[0022] Through the above technical solution, the output end of the servo motor 15 drives the positive and negative screws 16 to rotate. The positive and negative screws 16 use the effect of symmetrical threads to drive the two side sleeves 17 to move inward simultaneously. The sleeves 17 drive the clamping plate 18 to move inward, so that the inner side of the anti-slip pad 19 contacts the outer side of the workpiece. This can fix workpieces of different specifications, which is convenient for compatibility with workpieces of various sizes and avoids displacement caused by unilateral force. The output end of the stepper motor 3 drives the first turntable 5 to rotate. The first turntable 5 drives the workpiece to rotate through the transmission of the adjustment box 7, which facilitates automatic flipping of the workpiece, significantly reduces manual intervention, and ensures the consistency of the cutting surface. It is especially suitable for efficient continuous processing of profiles in prefabricated buildings, taking into account both positioning accuracy and ease of operation. By setting the sliding column 14 and the annular sliding groove 13, the smoothness of the first turntable 5 and the second turntable 6 during the rotation process can be effectively improved. By setting the longitudinal sliding groove 20 and the slider 21, the stability of the sleeve 17 during the up and down movement can be effectively improved.

[0023] Specifically, a laser cutting assembly 4 is installed on the top of the inner wall of the cutting box 2, a flow guide baffle 8 is fixedly connected to the bottom of the inner cavity of the cutting box 2, a bracket 9 is fixedly connected to the bottom of both the left and right sides of the inner wall of the cutting box 2, a filter screen 10 is clamped in the inner cavity of the bracket 9, a flow fan 11 is fixedly connected to the middle of the bottom of the inner cavity of the cutting box 2, the output end of the flow fan 11 extends to the right side of the cutting box 2, and a ventilation mesh 12 is embedded in the top of the right side of the cutting box 2.

[0024] Through the above technical solution, the suction generated at the input end of the induced flow fan 11 draws the air mixed with dust and debris downwards, and the dust and debris are trapped by the filter screen 10, which facilitates the collection and retention of dust and debris and avoids the direct discharge of dust and debris, which would have an adverse impact on the surrounding environment. By setting the bracket 9, the filter screen 10 can be disassembled for cleaning or replacement.

[0025] In use, the output of the servo motor 15 first drives the positive and negative screws 16 to rotate. The positive and negative screws 16 use the effect of symmetrical threads to drive the two side sleeves 17 to move inward at the same time. The sleeves 17 drive the clamping plate 18 to move inward, so that the inner side of the anti-slip pad 19 contacts the outer side of the workpiece to fix the workpiece. The output of the stepper motor 3 drives the first turntable 5 to rotate. The first turntable 5 drives the workpiece to rotate through the transmission of the adjustment box 7, which facilitates the automatic flipping of the workpiece. During the cutting process, the input of the exhaust fan 11 generates suction to draw the air mixed with dust and waste downward. The dust and waste are blocked by the filter screen 10, which facilitates the collection and retention of dust and waste and avoids the direct discharge of dust and waste, which will have an adverse effect on the surrounding environment.
