Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting support technology, and in particular to a PMMA composite board cutting auxiliary support. Background Technology
[0002] The main body of the PMMA composite board cutting auxiliary support frame consists of a base, support column, electrical box, cutting machine, connecting rod, and pin.
[0003] Existing technologies, such as the utility model with publication number CN214520534U, specifically disclose a composite board cutting auxiliary support, including a support leg assembly and a working platform. The working platform has a sealed cavity, and the top plate of the cavity has several mounting holes. Each mounting hole contains a bushing, and each bushing contains an inflatable floating ball bearing. An air compressor is installed at the bottom of the working platform to inflate the cavity. The multiple ball bearings can roll flexibly when pneumatically lifted, allowing the composite board to slide easily on it. A single worker can easily drag the board, greatly reducing worker fatigue. An auxiliary limiting plate is hinged to one side of the working platform. The limiting plate has a thickness scale. The limiting plate prevents the composite board from sliding off the platform and allows the thickness of the stacked composite boards to be read easily, thus easily calculating the quantity of composite boards and speeding up the production line. The support leg assembly is height-adjustable to adapt to machine tool processing surfaces of different heights.
[0004] The following defects were found in the above content: When using a traditional cutting bracket to cut PMMA composite board, the traditional cutting bracket has a poor limiting effect on PMMA composite board, which easily leads to incorrect cutting position of PMMA during cutting. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where traditional cutting supports are ineffective in limiting the position of PMMA composite boards during cutting, which can easily lead to incorrect cutting positions. Therefore, this invention proposes an auxiliary support for cutting PMMA composite boards.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a PMMA composite board cutting auxiliary support, comprising a base, a support column fixedly connected to the upper surface of the base, an electrical box fixedly connected to one end of the base, a connecting rod movably connected inside the support column, a pin threaded inside the support column, one end of the pin engaging with the connecting rod, a cutting machine fixedly connected to the arc surface of the connecting rod, a clamping device provided on the upper surface of the base, the clamping device comprising two clamping blocks, two pulleys slidably connected to the lower surfaces of the two clamping blocks, a groove provided on the upper surface of the base, the arc surfaces of the two pulleys slidably connected to the groove, and a handle fixedly connected to the upper surface of the clamping blocks.
[0007] The effect achieved by the above components is that when cutting PMMA composite sheets, moving the handle causes the clamping block to move, thereby clamping the PMMA composite sheets for cutting.
[0008] Preferably, a telescopic rod is fixedly connected to one end of each of the two clamping blocks that is far apart from each other, and the other end of the telescopic rod is fixedly connected to the base. A spring is fitted on the arc surface of the telescopic rod, and the two ends of the spring are fixedly connected to the clamping block and the base, respectively.
[0009] The effect achieved by the above components is that the spring provides elasticity, which achieves a better clamping effect on the PMMA composite board.
[0010] Preferably, an anti-slip pad is fixedly connected inside the clamping block, and the surface of the anti-slip pad is provided with anti-slip grooves.
[0011] The effect achieved by the above components is to increase friction when cutting PMMA composite sheets, making the PMMA composite sheets less prone to movement and achieving an anti-slip effect.
[0012] Preferably, a fixing block is fixedly connected to the upper surface of the clamping block, a connecting rod is movably connected to the inside of the fixing block, a support rod is fixedly connected to the arc surface of the connecting rod, a round rod is fixedly connected to the inside of the support rod, a support plate is movably connected to the arc surface of the round rod, a screw is threadedly connected to the inside of the support plate, the lower surface of the screw is engaged with the base, a movable pin is slidably connected to the inside of the support plate, and a base is fixedly connected to the lower surface of the movable pin.
[0013] The effect achieved by the above components is that when clamping the PMMA composite sheet, the support rod can provide tension to prevent the PMMA composite sheet from being clamped too tightly, which would cause the PMMA composite sheet to break.
[0014] Preferably, the upper surface of the base is provided with a conveying device, which includes two support blocks. The lower surfaces of the two support blocks are fixedly connected to the base. Several rollers are rotatably connected to the ends of the two support blocks that are close to each other. A motor is fixedly connected to one end of each roller. A wire is fixedly connected to the end of the motor that is away from the support block. One end of the wire is fixedly connected to the base. A fixing frame is fixedly connected to the arc surface of the motor. One end of the fixing frame is fixedly connected to the base.
[0015] The above components achieve the following effect: the motor provides power to drive the roller to rotate, and the roller drives the PMMA composite plate to move, thus achieving the function of transmission.
[0016] Preferably, an anti-slip ring is fixedly connected to the arc surface of the roller, and the arc surface of the anti-slip ring is uniformly provided with anti-slip patterns.
[0017] The effect achieved by the above components is that the anti-slip ring can increase the friction, so that the PMMA composite board will not slip when it is being conveyed, and the conveying will be smoother.
[0018] Preferably, a rotating rod is rotatably connected inside the support block, and a transport plate is fixedly connected to the arc surface of the rotating rod.
[0019] The effect achieved by the above components is that the rotating rod drives the transport plate to the appropriate position, transferring the PMMA composite board from the transport plate to the plate, making the transfer more labor-saving.
[0020] In summary, the beneficial effects of this utility model are as follows:
[0021] In this invention, before cutting PMMA composite boards, the pin in the support column needs to be pulled out first, and then the connecting rod is rotated. This moves the cutting frame upward to a certain position. Then, the pin is inserted, and then the two screws are pulled out. Moving the two handles drives the clamping blocks to move. Under the action of the pulleys, the clamping blocks move to their maximum position to both sides, and the two fixed blocks also move to both sides with the clamping blocks. The movement of the fixed blocks drives the connecting rod to move, causing the support rod to move as well. Then, the round rod moves with the support rod, and the moving block is pressed upward along the live pin by the supporting force. Then, the screws are inserted to fix the moving block. The spring is compressed, generating elastic force on the clamping blocks, causing the clamping blocks to tend to move in opposite directions. The fixed blocks also tend to move in opposite directions, making them want to move closer to each other. The connecting rod also tends to move due to the pressure of the fixed blocks, so the support rod and the round rod also tend to move. However, since the moving block is fixed, the clamping blocks are fixed.
[0022] In this invention, when conveying the PMMA composite board, the board is transferred from the transport plate to the rollers until it reaches a position where the clamping blocks can hold it. Then, two screws are pulled out, and two handles are moved closer together, causing the clamping blocks to move to a position where they can clamp the PMMA composite board. The screws are then inserted, and the clamping blocks are fixed in place. At this point, the PMMA composite board is positioned on the upper surface of the anti-slip pad and the upper surface of the anti-slip ring. When cutting the PMMA composite board, the pins are first pulled out. When a specific size of PMMA composite board is required, the connecting rod is rotated to position the cutting machine at a suitable position on the surface of the PMMA composite board. Then, the electrical control box is started to activate the motors of the cutting machine and the conveying device, thus completing the cutting process. When cutting is complete, first turn off the electrical box, then pull out the plug, rotate the connecting rod to move the cutting machine upwards to a certain position, then insert the plug, pull out the two screws. Under the spring force, the two clamping blocks are pressed and moved closer to each other, and the two fixed blocks also move closer to each other. This drives the connecting rod, support rod, and round rod to move, while the moving block moves downwards until the two clamping blocks are tightly pressed together. Then insert the screws to fix the moving block, thus fixing the clamping blocks. Then rotate the rotating rod to rotate the conveyor plate upwards until the conveyor plate is fixed. The anti-slip pads and anti-slip rings increase the friction of the conveyed PMMA composite board, making its conveying smoother. Attached Figure Description

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a PMMA composite board cutting auxiliary support, including a base 1, a support column 2 fixedly connected to the upper surface of the base 1, an electrical box 3 fixedly connected to one end of the base 1, a connecting rod 5 movably connected inside the support column 2, a pin 6 threadedly connected inside the support column 2, one end of the pin 6 engaging with the connecting rod 5, a cutting machine 4 fixedly connected to the arc surface of the connecting rod 5, a clamping device 7 provided on the upper surface of the base 1, and a conveying device 8 provided on the upper surface of the base 1.
[0030] The specific setup and function of its clamping and conveying devices will be discussed below.
[0031] Reference Figure 2 and Figure 3 and Figure 4As shown in this embodiment: the clamping device 7 includes two clamping blocks 701, and two pulleys 704 are slidably connected to the lower surfaces of the two clamping blocks 701. A groove 714 is opened on the upper surface of the base 1, and the arc surfaces of the two pulleys 704 are slidably connected to the groove 714. A handle 703 is fixedly connected to the upper surface of the clamping block 701. When cutting the PMMA composite board, the handle 703 is moved to move the clamping block 701, thereby clamping the PMMA composite board for cutting. A telescopic rod 705 is fixedly connected to one end of the two clamping blocks 701 that is far apart from each other. The other end of the telescopic rod 705 is fixedly connected to the base 1. A spring 706 is sleeved on the arc surface of the telescopic rod 705. The two ends of the spring 706 are fixedly connected to the clamping block 701 and the base 1 respectively. The spring 706 provides elastic force, achieving a better clamping effect on the PMMA composite board. An anti-slip pad 702 is fixedly connected inside the clamping block 701. The surface of the anti-slip pad 702 has anti-slip grooves, which increase friction when cutting PMMA composite board, making it less likely for the PMMA composite board to move and achieving an anti-slip effect. A fixing block 707 is fixedly connected to the upper surface of the clamping block 701. A connecting rod 708 is movably connected inside the fixing block 707. A support rod 709 is fixedly connected to the arc surface of the connecting rod 708. A round rod 713 is fixedly connected inside the support rod 709. A support plate 712 is movably connected to the arc surface of the round rod 713. A screw 710 is threaded inside the support plate 712. The lower surface of the screw 710 is engaged with the base 1. A movable pin 711 is slidably connected inside the support plate 712. The lower surface of the movable pin 711 is fixedly connected to the base 1. When clamping the PMMA composite board, the support rod 709 can provide tension to prevent the PMMA composite board from being clamped too tightly, which could cause the PMMA composite board to break.
[0032] Reference Figure 5 As shown in this embodiment: the conveying device 8 includes two support blocks 81, the lower surfaces of which are fixedly connected to the base 1. Several rollers 82 are rotatably connected to the ends of the two support blocks 81 that are close to each other. A motor 86 is fixedly connected to one end of each roller 82, and an electric wire 87 is fixedly connected to the end of the motor 86 away from the support block 81. One end of the electric wire 87 is fixedly connected to the base 1. A fixing frame 88 is fixedly connected to the arc surface of the motor 86, and one end of the fixing frame 88 is fixedly connected to the base 1. The motor 86 provides power to drive the rollers 82 to rotate, and the rollers 82 drive the PMMA composite board to move, thus achieving the conveying function. Anti-slip rings 83 are fixedly connected to the arc surface of the rollers 82. The arc surface of the anti-slip rings 83 is evenly provided with anti-slip patterns. The anti-slip rings 83 can increase friction, preventing slippage when conveying the PMMA composite board and making the conveying smoother. The support block 81 is internally connected to a rotating rod 84, and the arc surface of the rotating rod 84 is fixedly connected to a transport plate 85. Rotating the rotating rod 84 drives the transport plate 85 to rotate to a suitable position, so that the PMMA composite board is transferred from the transport plate 85 to the plate, making the transfer more labor-saving.
[0033] Working principle: In this invention, before cutting PMMA composite boards, the pin 6 in the support column 2 needs to be pulled out first, and then the connecting rod 5 is rotated. This moves the cutting frame upward to a certain position, then the pin 6 is inserted, and then the two screws 710 are pulled out. Moving the two handles 703 drives the clamping block 701 to move. Under the action of the pulley 704, it moves to the maximum position on both sides, and the two fixed blocks 707 also move to both sides with the clamping block 701. The movement of the fixed blocks 707 drives the connecting rod 708 to move, causing the support rod 709 to move as well. Then the round rod 713 moves with the support rod 709, and the moving block is pressed along the movable pin 71 by the supporting force. 1. Move upwards and then insert screw 710 to fix the moving block. The spring 706 is compressed to generate elastic force on the clamping block 701, causing the clamping block 701 to tend to move in the same direction as each other. The fixing block 707 also tends to move in the same direction as each other, causing the fixing block 707 to move closer to each other. The connecting rod 708 also tends to move due to being compressed by the fixing block 707. Therefore, the support rod 709 and the round rod 713 also tend to move. However, since the moving block is fixed, the clamping block 701 is fixed.
[0034] In this invention, when the PMMA composite board needs to be conveyed, it is transferred from the transport plate 85 to the roller 82 and conveyed to a position where the clamping block 701 can hold it. Then, the two screws 710 are pulled out, and the two handles 703 are pulled closer together, moving the two clamping blocks 701 to a position where they can clamp the PMMA composite board. Then, the screws 710 are inserted, and the clamping blocks 701 are fixed. At this time, the PMMA composite board is on the upper surface of the anti-slip pad 702 and the upper surface of the anti-slip ring 83. When cutting the PMMA composite board, the pin 6 is first pulled out. When a PMMA composite board of a certain size is needed, the connecting rod 5 is rotated and pulled to position the cutting machine 4 at a suitable position on the surface of the PMMA composite board. Then, the electrical box 3 is started to start the motor 86 of the cutting machine 4 and the conveying device 8, thus completing the cutting. When cutting is complete, first turn off the electrical box 3, then pull out the pin 6, rotate and pull the connecting rod 5 to move the cutting machine 4 upward to a certain position, then insert the pin 6, pull out the two screws 710, and under the elastic force of the spring 706, the two clamping blocks 701 are squeezed and moved closer to each other, and the two fixed blocks 707 also move closer to each other. This drives the connecting rod 708, the support rod 709, and the round rod 713 to move, while the moving block moves downward until the two clamping blocks 701 are pressed tightly together. Then insert the screws 710 to fix the moving block, thus fixing the clamping blocks 701. Then rotate the rotating rod 84 to rotate the transport plate 85 upward until the transport plate 85 is fixed. The anti-slip pad 702 and the anti-slip ring 83 increase the friction of the transported PMMA composite board, making its transport smoother.
