Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of glass cutting clamp devices, and in particular to an auxiliary clamp for cutting glass cover plates. Background Technology
[0002] In the cutting process of glass cover plates, the design of the clamps is crucial, especially in ensuring the glass is securely held and prevented from breaking, while also guaranteeing precision and safety during the cutting process. To address these issues, existing technologies have gradually introduced buffer structures, adjustment devices, and more precise clamping systems. However, existing technologies still have some shortcomings, mainly manifested in the insufficient precision of the clamping force and position adjustment of the glass, failing to meet the high requirements for glass surface protection. Especially when dealing with the fragile nature of glass, preventing damage caused by uneven or excessive pressure remains a challenge.
[0003] Conventional clamps mostly use metal clamping structures and lack a buffer mechanism. When clamping, excessive local pressure can easily cause micro-cracks or chipping on the glass surface. This risk of breakage increases significantly, especially in the processing of thin glass. Furthermore, during the cutting process, the superposition of thermal stress and mechanical vibration can easily cause the glass to shift. If even a slight movement occurs, it can lead to the deviation of the cutting line or the generation of burrs. Therefore, improvements are needed. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a glass cover plate cutting auxiliary fixture.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a glass cover plate cutting auxiliary fixture, including a worktable, a pad fixedly connected to the top of the worktable, through grooves opened on both the pad and the top of the worktable, a clamping frame fixedly connected to the bottom of the pad and below the through grooves, two moving blocks slidably connected inside the clamping frame, a driving component capable of driving the two moving blocks to move relative to or away from each other is provided on one side of the worktable, a hollow block is fixedly connected to the top of each of the two moving blocks, a guide component is provided between the opposite sides of the two hollow blocks, a buffer groove is opened inside the hollow block, a buffer component is provided on the buffer groove, and several clamping components are provided on both sides of the hollow block.
[0006] The worktable serves as the support base for the fixture, and the pad serves as the direct contact surface for the glass. The pad is made of polyurethane or nylon 66, taking into account both anti-slip and anti-scratch requirements. The clamping frame remains stable during the cutting process, ensuring that the sliding of the moving block is not disturbed. The hollow block is equipped with a buffer groove and buffer components to help absorb the pressure and vibration generated during clamping and prevent damage to the glass.
[0007] As a further description of the above technical solution:
[0008] The drive assembly includes a drive motor fixedly mounted on one side of the workbench. The output end of the drive motor rotates through the interior of the clamping frame and is fixedly connected to a bidirectional threaded rod.
[0009] The drive motor outputs torque to the bidirectional threaded rod, which drives the moving block to move symmetrically through the positive and negative threads, thereby adjusting the clamping range.

Through the guide rod and the fixed seat, the hollow block maintains a stable movement trajectory to prevent tilting or misalignment during clamping. The fixed seat fixes the guide rod to the worktable to ensure that the hollow block can move stably along the predetermined path.
[0015] As a further description of the above technical solution:
[0016] The buffer assembly includes a rubber block that is slidably connected to the inner wall of the buffer groove, and several springs are fixedly installed on one side of the rubber block.
[0017] One end of the spring is fixedly connected to the inner wall of the hollow block. The spring and the rubber block work together to provide additional elastic support, ensuring that the buffer assembly can automatically adjust its elasticity according to the thickness and material of the glass, further preventing the glass from breaking.
[0018] As a further description of the above technical solution:
[0019] The clamping assembly includes a clamping seat and a movable seat that are detachably clamped on both sides of the hollow block. A clamping seat is fixedly connected to the top of the clamping seat, a clamping rod is threadedly connected to the inside of the clamping seat, and a trapezoidal track is fixedly connected to the bottom of the clamping seat.
[0020] By adjusting the clamping rod, the glass cover is secured during clamping to prevent loosening or displacement. The bottom of the clamping rod is equipped with a silicone pad, and the trapezoidal track provides guidance and support for the moving seat, keeping it stable during adjustment and ensuring a smooth and effective clamping operation.

[0027] This utility model has the following beneficial effects:
[0028] 1. Compared with existing technologies, this glass cover cutting auxiliary clamp, through the coordinated use of a clamping frame, hollow block, drive assembly, and buffer assembly, can precisely adjust the clamping position and force through the design of the bidirectional threaded rod and hollow block, ensuring that the glass cover is stable and uniformly clamped during the clamping process. Furthermore, through the cooperation of rubber blocks and springs, the elasticity can be automatically adjusted according to the thickness and material of the glass, providing a uniform buffering effect and avoiding glass breakage or cracks caused by uneven clamping force.
[0029] 2. Compared with the prior art, this glass cover cutting auxiliary fixture, through the coordinated use of structures such as clamping seat, moving seat, pressing seat and pressing rod, can drive the moving seat to slide along the trapezoidal track by adjusting the rod, so as to realize the quick positioning of the pressing device.

A clamping frame 4 is fixedly connected to the bottom of the pad 2 and below the through slots 3. Two moving blocks 5 are slidably connected inside the clamping frame 4. A driving component capable of driving the two moving blocks 5 to move relative to or away from each other is provided on one side of the worktable 1. A hollow block 6 is fixedly connected to the top of each of the two moving blocks 5. A guide component is provided between the opposite sides of the two hollow blocks 6.

The worktable 1 is the supporting base of the fixture. The pad 2 is the direct contact surface of the glass. The pad 2 is made of polyurethane material, which takes into account the requirements of anti-slip and anti-scratch. The clamping frame 4 remains stable during the cutting process, ensuring that the sliding of the moving block 5 is not disturbed. The hollow block 6 has a buffer groove 7 and a buffer component inside to help absorb the pressure and vibration generated during clamping and prevent damage to the glass. Through the coordinated use of the clamping frame 4, the hollow block 6, the drive component and the buffer component, the fixture can accurately adjust the clamping position and force through the design of the bidirectional threaded rod 9 and the hollow block 6, ensuring that the glass cover is stable and uniform during clamping. Furthermore, through the cooperation of the rubber block 12 and the spring 13, the elasticity can be automatically adjusted according to the thickness and material of the glass to provide a uniform buffering effect and avoid glass breakage or cracks caused by uneven clamping force.
[0038] The drive assembly includes a drive motor 8 fixedly mounted on one side of the workbench 1. The output end of the drive motor 8 rotates through the inside of the clamping frame 4 and is fixedly connected to a bidirectional threaded rod 9. The output torque of the drive motor 8 is transmitted to the bidirectional threaded rod 9, which drives the moving blocks 5 to move symmetrically through the positive and negative threads, thereby adjusting the clamping range. The outer wall of the bidirectional threaded rod 9 is threadedly connected to the two moving blocks 5, and one end of the bidirectional threaded rod 9 is rotatably connected to the inner wall of the clamping frame 4.
[0039] The guiding assembly includes two guide rods 10 slidably connected between two hollow blocks 6 on opposite sides. Both ends of the guide rods 10 pass through the hollow blocks 6 and are fixedly connected to a fixed seat 11. The bottom of the fixed seat 11 is fixedly connected to the top of the worktable 1. Through the guide rods 10 and the fixed seat 11, the hollow blocks 6 maintain a stable movement trajectory to prevent tilting or misalignment during clamping. The fixed seat 11 fixes the guide rods 10 to the worktable 1, ensuring that the hollow blocks 6 can move stably along the predetermined path.
[0040] The buffer assembly includes a rubber block 12 that is slidably connected to the inner wall of the buffer groove 7. Several springs 13 are fixedly installed on one side of the rubber block 12. One end of the spring 13 is fixedly connected to the inner wall of the hollow block 6. The spring 13 cooperates with the rubber block 12 to provide additional elastic support, ensuring that the buffer assembly can automatically adjust its elasticity according to the thickness and material of the glass, further preventing the glass from breaking.
[0041] The clamping assembly includes a clamping seat 14 and a movable seat 15 that are detachably clamped on both sides of the hollow block 6. A clamping seat 16 is fixedly connected to the top of the clamping seat 14. A clamping rod 17 is threadedly connected to the inside of the clamping seat 16. A trapezoidal track 18 is fixedly connected to the bottom of the clamping seat 16. By adjusting the clamping rod 17, the glass cover is ensured to be secure during clamping, preventing loosening or displacement. A silicone pad is provided at the bottom of the clamping rod 17. The trapezoidal track 18 provides guidance and support for the movable seat 15, keeping it stable during adjustment and ensuring smooth and effective clamping operation. An adjusting rod 19 is threadedly connected to the inside of the movable seat 15. The outer wall of the adjusting rod 19 is rotatably connected to the inside of the clamping seat 14. The top of the movable seat 15 is slidably connected to the trapezoidal track 18.
[0042] A cutting mechanism 20 is installed on the worktable 1 and is responsible for the actual cutting operation. This mechanism usually includes a cutting tool or a laser system, which can accurately cut the glass cover plate as needed.
[0043] Working principle: First, when using the device, place the glass cover plate on the pad 2, then start the drive motor 8 to rotate its output end, which in turn drives the bidirectional threaded rod 9 to rotate. This allows the two moving blocks 5 on the bidirectional threaded rod 9 to move relative to each other along the inner wall of the clamping frame 4, which in turn drives the hollow block 6 to move relative to each other. This causes the rubber block 12 to clamp the glass cover plate. During the clamping process, the hollow block 6 continues to move, causing the rubber block 12 to push the spring 13 to compress. This causes the spring 13 to deform and allows the rubber block 12 to move within the buffer groove 7 inside the hollow block 6. This allows the spring 13 to automatically adjust its elasticity according to the thickness and material of the glass, thereby achieving uniform buffering of the glass. The rubber block 12 further reduces the impact, effectively preventing the glass from being subjected to excessive direct pressure during clamping. This avoids the glass from cracking or breaking due to uneven pressure or excessive impact, significantly improving the clamp's ability to protect the glass and ensuring the safety of the glass.
[0044] After clamping, the adjusting rod 19 can be rotated to allow the movable seat 15, which is threaded onto the outer wall of the adjusting rod 19, to move along the trapezoidal track 18, thereby releasing the clamping of the hollow block 6. Then, it is moved above the glass cover. At this point, the adjusting rod 19 is rotated in the opposite direction to allow the movable seat 15 to move towards the clamping seat 14, thus clamping it onto the hollow block 6. Then, the clamping rod 17 can be rotated to press the silicone pad at its bottom against the glass cover, further preventing loosening.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
