Description

Technical Field

[0001] This application relates to the field of cutting equipment technology, and in particular to a fixing device for cutting building construction materials. Background Technology

[0002] In construction, it is often necessary to cut various building materials to form the required shape or length. In order to prevent the building materials from shifting during cutting, improve cutting accuracy, and reduce burrs, it is generally necessary to fix the building materials first.

[0003] A search revealed that Chinese Patent No. CN 221134319 U discloses a metal pipe cutting device. This device uses four sets of guide wheels to support the inner wall of the pipe, ensuring that the pipe interior at both ends of the cutting position is supported during operation. This results in more uniform force on the pipe workpiece, reducing burrs and preventing pipe deformation. However, when fixing pipes of different diameters, the inability to adjust the coaxiality between the base block and the pipe leads to inconsistent guide wheel extension lengths and unbalanced support forces, which can easily cause pipe deformation. Therefore, a fixing device for cutting building construction materials is proposed to solve the above problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-6 This utility model provides a technical solution for a fixing device for cutting building construction materials:

[0026] A fixing device for cutting building construction materials, used to fix cut pipes 3 during construction, includes: a base 1, on which a fixing component 2 is fixedly connected for fixing the pipes 3; an inner support component 4, disposed on the base 1, the inner support component 4 including two movable parts 41 that can move towards or away from each other, a sliding rod 42 that slides perpendicular to the axis of the pipe 3 is provided on the side of the movable part 41 near the pipe 3, the sliding rod 42 is made of heat-treated and strengthened alloy structural steel, and a support member 43 is fixedly connected to one end of the sliding rod 42; the support member 43 is a radially adjustable structure, which can expand or shrink its radial dimension to adapt to the inner wall of the pipe 3 of different diameters, when the support member 43 contacts and supports the inner wall of the pipe 3, it can drive the support member 43 to automatically adjust its position so that the axis of the sliding rod 42 coincides with the axis of the pipe 3; and a locking member 5, disposed on the sliding rod 42, used to lock the position of the sliding rod 42 after the axis of the sliding rod 42 coincides with the axis of the pipe 3.

[0027] Specifically, the movable part 41 drives the sliding rod 42 to move laterally, which in turn drives the support member 43 to extend into the interior of the pipe 3 from both ends and move to a position close to the cutting position. The cutting position is located between the two support members 43. By setting the radially adjustable support member 43, the radial dimension is expanded at the target position. When the support member 43 contacts and supports the inner wall of the pipe 3, it drives the support member 43 to automatically adjust its position so that the axis of the sliding rod 42 coincides with the axis of the pipe 3. By setting the locking member 5, the position of the sliding rod 42 is locked after the axis of the sliding rod 42 coincides with the axis of the pipe 3, keeping the two axes coincident, so that the support member 43 provides uniform support force to the inner wall of the pipe 3, reducing the deformation of the pipe 3 caused by force imbalance.

[0028] The upper surface of the base 1 is provided with a sliding groove. The movable part 41 includes a slider 411 that is slidably connected to the inner wall of the sliding groove. A connecting rod 412 is fixedly connected to the top of the slider 411, and a vertical rod 413 is fixedly connected to the end of the connecting rod 412. The sliding rod 42 is slidably connected to the vertical rod 413. By setting the connecting rod 412, the slider 411 is closer to the cutting position relative to the vertical rod 413, thereby reducing the length of the device when the movable part 41 is retracted.

[0029] The side of the upright 413 has a limiting groove opened in the vertical direction, and the sliding rod 42 is slidably connected to the inner wall of the limiting groove, so that the sliding rod 42 can move up and down in the vertical direction. The upper and lower surfaces of the sliding rod 42 are fixedly connected to springs 44, and the other ends of the two springs 44 are fixedly connected to the inner top wall and inner bottom wall of the limiting groove, respectively, for supporting the sliding rod 42.

[0030] The sliding rod 42 has a mounting groove at its end, and a locking element 5 is located inside the mounting groove. The locking element 5 includes two wedge-shaped blocks 51 that are slidably connected to the inner wall of the mounting groove. The inner wall of the mounting groove has a clearance opening for the passage of the wedge-shaped blocks 51. An end cap 52 is fixedly connected to the inner wall of the mounting groove. A threaded hole is provided on the side of the end cap 52, and a screw 53 is threadedly connected to the inner wall of the threaded hole. One end of the screw 53 is fixedly connected to a conical separation pressure head 54 corresponding to the two wedge-shaped blocks 51. The other end of 53 is fixedly connected to a handwheel 55. By rotating the handwheel 55, the screw 53 is driven to rotate, and then the screw 53 moves axially under the cooperation of the threaded hole. The screw 53 drives the separating pressure head 54 to approach the wedge block 51 and insert it between the two wedge blocks 51, so that the two wedge blocks 51 move away from each other and pass through the clearance opening to form a pressure against the inner wall of the limiting groove, so that the sliding rod 42 is locked. The wedge block 51 is used to press against the inner wall of the limiting groove to reduce the impact of vibration and prevent loosening.

[0031] The support member 43 includes a cylindrical body 431 with open ends. Multiple sliding grooves are formed on the surface of the cylindrical body 431. Two movable blocks 432 are slidably connected to the inner wall of each sliding groove. Support ears 433 are provided on the surface of each movable block 432. A rotating rod 434 is rotatably connected to the top of each movable block 432. The other ends of the two rotating rods 434 are rotatably connected to the same support plate 435. A rubber pad is fixedly connected to the outer side of the support plate 435. Two movable plates 437 are coaxially arranged inside the cylindrical body 431. The surface of the movable plates 437 is fixedly connected to multiple movable blocks 432 on the same side. Two side covers 438 are fixedly connected to the inner wall of the cylindrical body 431. A first bidirectional threaded screw 439 is rotatably connected between the two side covers 438. The two movable plates 437 are threadedly connected to the two helical sections of the first bidirectional threaded screw 439, respectively. The side cover 438 near the sliding rod 42... A first motor 430 is fixedly connected to the side of the cylinder 431. The output end of the first motor 430 is fixedly connected to one end of the first bidirectional threaded screw 439. A fixed cover 436 is fitted around the first motor 430. The fixed cover 436 is fixedly connected to one end of the cylinder 431 near the sliding rod 42. The fixed cover 436 and one end of the sliding rod 42 are coaxially fixedly connected. The output end of the first motor 430 drives the first bidirectional threaded screw 439 to rotate, which in turn drives the two movable plates 437 to move closer to each other, which in turn drives the two sets of moving blocks 432 to move closer to each other, which in turn drives the rotating rod 434 to move, which in turn causes the support plate 435 to move away from the cylinder 431 until the rubber pad presses against the inner wall of the pipe 3, forming an internal support to prevent the pipe 3 from deforming. The support ear 433 is used to reduce the radial pressure on the first bidirectional threaded screw 439 to ensure that it can work normally.

[0032] The inner wall of the chute rotates with two second bidirectional threaded screws 45. Two sliders 411 are respectively threaded to the two helical sections of the second bidirectional threaded screws 45. A second motor 46 is fixedly connected to one side of the base 1. The output end of the second motor 46 is fixedly connected to one end of the second bidirectional threaded screw 45. The output end of the second motor 46 drives the second bidirectional threaded screw 45 to rotate, thereby driving the two movable parts 41 to move closer to each other, thereby driving the two sliding rods 42 to move closer to each other, thereby driving the support member 43 to extend into the interior of the tube 3 from both ends and move to the position close to the cutting position.

[0033] The fixing component 2 includes two sets of bottom supports 21. Each set of bottom supports 21 includes two horizontally arranged support seats 211. The two support seats 211 are located on the front and rear sides of the upper surface of the base 1, and the top of the support seats 211 is semi-circular. The inner support component 4 is arranged between the front and rear support seats 211. The outer side of the base 1 is fixedly connected to the upright 22 corresponding to the bottom support 21. The inner wall of the upright 22 is slidably connected to the sliding plate 23. The lower surface of the sliding plate 23 is fixedly connected to two pressure rods 24. The top of the upright 22 is fixedly connected to the cylinder 25. The output end of the cylinder 25 is fixedly connected to the sliding plate 23. The pipe 3 is supported from below by the support seats 211. The output end of the cylinder 25 drives the sliding plate 23 to move downward, thereby driving the pressure rods 24 to move downward, pressing the pipe 3 from above, so that the pipe 3 is fixed.

[0034] Working principle: When using this construction material cutting and fixing device, the user first places the pipe 3 between the front and rear support seats 211, with the cutting position between the two sets of bottom supports 21. Then, the cylinder 25 is activated. The output end of the cylinder 25 drives the sliding plate 23 to move downwards, and the sliding plate 23 drives the pressure rod 24 to move downwards. The pressure rod 24 presses the pipe 3 from above, fixing the pipe 3. Then, the second motor 46 is activated. The output end of the second motor 46 drives the second bidirectional threaded screw 45 to rotate. The second bidirectional threaded screw 45 drives the two movable parts 41 to move closer to each other. The two movable parts 41 drive the two sliding rods 42 to move closer to each other. The two sliding rods 42 drive the support member 43 to extend into the pipe 3 from both ends and move to a position close to the cutting position. Then, the first motor 430 is activated. The output end of the first motor 430 drives the first bidirectional threaded screw 439 to rotate. The first bidirectional threaded screw 439 drives the two movable plates 437 to move closer to each other. The movable plate 437 drives two sets of moving blocks 432 to move closer to each other. The two sets of moving blocks 432 drive the rotating rod 434 to move, thereby causing the support plate 435 to move away from the cylinder 431 until the rubber pad presses against the inner wall of the pipe 3, forming internal support and preventing deformation of the pipe 3. During this process, when the support plate 435 contacts and supports the inner wall of the pipe 3, it drives the support member 43 to automatically adjust its position, so that the axis of the sliding rod 42 coincides with the axis of the pipe 3. Then, the handwheel 55 is turned. 5 drives the screw 53 to rotate, and with the cooperation of the threaded hole, the screw 53 moves axially. The screw 53 drives the separation pressure head 54 to approach the wedge block 51 and insert it between the two wedge blocks 51, so that the two wedge blocks 51 move away from each other and pass through the clearance opening to form a pressure against the inner wall of the limiting groove, so that the sliding rod 42 is locked. This allows the fixing device for cutting building construction materials to make the support member 43 provide uniform support force to the inner wall of the pipe 3, reducing the deformation of the pipe 3 caused by force imbalance.
