AI Technical Summary
In the existing fiberglass board cutting process, because traditional clamps only hold the material at the edge or in a fixed area, the area far from the clamps becomes a "free end" due to the cantilever effect during cutting. This free end is easily affected by tool vibration and cutting force, resulting in high-frequency vibration, which leads to burrs and dimensional deviations in the cut and affects the cutting quality.
An auxiliary positioning mechanism for cutting fiberglass board is adopted, including a positioning support platform, a first positioning module, a second positioning module, a cutting clamping platform, a clamping drive cylinder, and a dynamic clamping mechanism. Multi-angle clamping is achieved through clamping drive screw and clamping compression screw, and a rubber structure is used for buffering. Combined with the moving clamping plate of the dynamic clamping mechanism following the cutting position, it provides local rigid support and suppresses vibration.
This improved the stability and precision of fiberglass boards during the cutting process, reduced the impact of vibration, and enhanced cutting quality and accuracy.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of fiberglass board processing equipment, and more specifically, it relates to an auxiliary positioning mechanism for cutting fiberglass boards. Background Technology
[0002] Fiberglass boards have advantages such as high strength and good insulation, and are widely used in the manufacture of automotive center console panels, circuit boards and structural components for consumer electronic devices (such as mobile phones and laptops). During the cutting and processing of fiberglass boards, the positioning accuracy directly affects the cutting quality. Currently, pneumatic clamps are generally used to clamp and position the fiberglass boards during cutting.
[0003] The existing application number is CN202122008898.5. This utility model relates to a fiberglass board traction cutting device, including a support platform. Several support legs are fixedly connected to the bottom of the support platform, and a fixed frame is fixedly connected to one side of its top. A cutting mechanism is arranged below the fixed frame, and a cutting table is arranged on one side of the fixed frame. The cutting table has a storage cavity inside, several chip guide holes on its top surface, and positioning mechanisms on both sides of the top of the cutting table. A chip collection groove is arranged in the storage cavity. A traction mechanism is arranged between the cutting table and the fixed frame, and a side plate is arranged on the other side of the cutting table. A spring is fixedly connected between the side plate and the outer wall of the cutting table. This utility model has the advantages of reasonable structural design, enabling traction cutting, effectively expanding the cutting range, quickly adjusting the cutting point position, improving work efficiency, and timely recycling of glass debris generated during the cutting process. Furthermore, the fiberglass board is less prone to displacement during the cutting process, resulting in high cutting precision.
[0004] Based on the above, when cutting and clamping fiberglass boards, since mobile phones, laptops and car center console panels generally use thin fiberglass boards, traditional fixing clamps only clamp the material at the edge or fixed area. During cutting, the area far from the clamp forms a "free end" due to the cantilever effect, which is easily subjected to high-frequency vibration from the tool vibration and cutting force impact, resulting in burrs and dimensional deviations, affecting the cutting quality of the fiberglass board. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides an auxiliary positioning mechanism for cutting fiberglass boards. This addresses the issue that existing clamping mechanisms, when cutting and holding fiberglass boards, often only hold the material at the edge or in a fixed area. Since mobile phones, laptops, and automotive center consoles typically use thin fiberglass boards, traditional clamping devices only hold the material at the edge or in a fixed area. During cutting, areas far from the clamping device become "free ends" due to the cantilever effect, making them susceptible to high-frequency vibrations from the cutting tool and the impact of the cutting force. This results in burrs, dimensional deviations, and affects the cutting quality of the fiberglass board.
[0006] The purpose and function of this utility model's auxiliary positioning mechanism for cutting fiberglass boards are achieved through the following specific technical means:
[0007] An auxiliary positioning mechanism for cutting fiberglass boards includes a positioning support platform, a first positioning module, a second positioning module, a cutting clamping platform, a clamping drive cylinder, a cutting clamping mechanism, and a dynamic clamping mechanism. The first positioning module is fixedly connected to the upper end of the positioning support platform. The second positioning module is fixedly connected above the slide of the first positioning module. The cutting clamping platform is fixedly connected to the upper end of the slide of the second positioning module, and a sliding groove structure is provided above the cutting clamping platform. The clamping drive cylinder is located at the upper front end of the cutting clamping platform. The cutting clamping mechanism is located above the cutting clamping platform. The dynamic clamping mechanism is located at the upper front end of the cutting clamping platform.
[0008] Furthermore, the cutting clamping mechanism includes: a first clamping member and a clamping drive screw; two sets of the first clamping members are provided, and the two sets of first clamping members are slidably connected to the upper inner side of the slide groove of the cutting clamping table; the clamping drive screw is a double-ended screw structure, and the clamping drive screw is rotatably connected to the inner side of the cutting clamping table, and the left and right sides of the clamping drive screw are threadedly connected to the first clamping member respectively.
[0009] Furthermore, the cutting clamping mechanism also includes: clamping guide rods, second clamping members, and clamping compression screws; four sets of clamping guide rods are provided, and the four sets of clamping guide rods are slidably connected above the first clamping member; two sets of second clamping members are provided, and the two sets of second clamping members are fixedly connected to the lower end of the clamping guide rods, and both sets of second clamping members are rubber plate structures; two sets of clamping compression screws are provided, and the two sets of clamping compression screws are rotatably connected above the second clamping member, and the two sets of clamping compression screws are threadedly connected to the first clamping member.
[0010] Furthermore, the dynamic clamping mechanism includes: a dynamic clamping frame, a clamping sliding block, and a clamping sliding screw; the dynamic clamping frame is fixedly connected to the upper front end of the cutting clamping table; the clamping sliding block is slidably connected to the inner side of the dynamic clamping frame, and the clamping drive cylinder is fixedly connected to the upper side of the clamping sliding block; the clamping sliding screw is rotatably connected to the inner side of the dynamic clamping frame, and the clamping sliding screw is threadedly connected to the clamping sliding block.
[0011] Furthermore, the dynamic clamping mechanism also includes a clamping moving motor; the clamping moving motor is fixedly connected to the right side of the dynamic clamping frame, and the clamping moving motor is driven by the clamping moving lead screw.
[0012] Furthermore, the dynamic clamping mechanism also includes: a pressure sensor and a movable clamping plate; the pressure sensor is fixedly connected to the lower end of the piston rod of the clamping drive cylinder, and the pressure sensor is electrically connected to the control circuit of the clamping drive cylinder; the movable clamping plate is fixedly connected to the lower end of the pressure sensor.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention utilizes a cutting and clamping mechanism to place a fiberglass board above the cutting and clamping table. Rotating the clamping drive screw causes the first clamping member to move in the opposite direction, thus clamping the fiberglass board. Then, rotating the clamping extrusion screw causes the second clamping member to move downwards, further clamping the fiberglass board. This multi-angle clamping of the fiberglass board ensures stability during cutting. Simultaneously, the rubber structure of the second clamping member provides a buffering effect during cutting, reducing the impact of vibration on the fiberglass board and improving the processing quality.
[0015] This invention utilizes a dynamic clamping mechanism. When the clamping moving motor is activated, its rotating shaft drives the clamping moving lead screw, which in turn moves the clamping moving slider left and right. This movement of the slider, in turn, moves the clamping drive cylinder left and right. Simultaneously, the clamping drive cylinder is activated, and its piston rod moves downward, causing a pressure sensor to move downward. This downward movement of the pressure sensor, in turn, moves the moving clamping plate downward, thus clamping the fiberglass board. This dynamic clamping of the fiberglass board, achieved through the movement of the clamping plate, allows it to follow the cutting position. By constantly following the cutting tool, it provides localized rigid support near the cutting point, shortening the material's "suspended length," suppressing vibration, and improving cutting accuracy.

[0026] The cutting clamping mechanism includes a first clamping member 101 and a clamping drive screw 102. Two sets of first clamping members 101 are provided, and the two sets of first clamping members 101 are slidably connected to the upper side of the inner side of the slide groove of the cutting clamping table 4.

[0027] The cutting clamping mechanism further includes: clamping guide rods 103, second clamping members 104, and clamping extrusion screws 105; four sets of clamping guide rods 103 are provided, and the four sets of clamping guide rods 103 are slidably connected above the first clamping member 101; two sets of second clamping members 104 are provided, and the two sets of second clamping members 104 are fixedly connected to the lower end of the clamping guide rods 103, and both sets of second clamping members 104 are rubber plate structures; two sets of clamping extrusion screws 105 are provided, and the two sets of clamping extrusion screws 105 are rotatably connected above the second clamping member 104, and the two sets of clamping extrusion screws 105 are threadedly connected to the first clamping member 101.
[0028] The specific usage and function of this embodiment are as follows: When it is necessary to cut the fiberglass board, firstly, the fiberglass board is placed above the cutting clamping table 4. The clamping drive screw 102 is rotated, which drives the first clamping member 101 to move in opposite directions.

Example 2
[0029] This utility model provides an auxiliary positioning mechanism for cutting fiberglass boards, based on Embodiment 1, such as... Figures 1 to 5 As shown, it also includes a dynamic clamping mechanism, which is located at the upper front end of the cutting clamping table 4.
[0030] The dynamic clamping mechanism includes: a dynamic clamping frame 501, a clamping sliding block 502, and a clamping sliding screw 503; the dynamic clamping frame 501 is fixedly connected to the upper front end of the cutting clamping table 4; the clamping sliding block 502 is slidably connected to the inner side of the dynamic clamping frame 501, and the clamping drive cylinder 5 is fixedly connected to the upper part of the clamping sliding block 502; the clamping sliding screw 503 is rotatably connected to the inner side of the dynamic clamping frame 501, and the clamping sliding screw 503 is threadedly connected to the clamping sliding block 502.
[0031] The dynamic clamping mechanism also includes a clamping moving motor 504; the clamping moving motor 504 is fixedly connected to the right side of the dynamic clamping frame 501, and the clamping moving motor 504 is connected to the clamping moving lead screw 503 for transmission.

[0033] The specific usage and function of this embodiment are as follows: When cutting the fiberglass board, the clamping moving motor 504 is activated. The rotating shaft of the clamping moving motor 504 rotates, causing the clamping moving screw 503 to rotate. The rotation of the clamping moving screw 503 causes the clamping moving slider 502 to move left and right. The left and right movement of the clamping moving slider 502 causes the clamping drive cylinder 5 to move left and right. At the same time, the clamping drive cylinder 5 is activated. The piston rod of the clamping drive cylinder 5 moves downward, causing the pressure sensor 505 to move downward.
