Description

Technical Field

[0001] The utility model relates to the technical field of tempered glass processing, and particularly relates to a positioning and clamping device for tempered glass processing. Background Art

[0002] Tempered glass is a kind of glass with compressive stress on the surface, also known as strengthened glass. Its strength is several times higher than that of ordinary glass and it has better bending resistance. Its load-bearing capacity increases, and the fragile property is improved. Even if the tempered glass is damaged, it will break into small pieces without sharp corners, greatly reducing the harm to the human body. During the processing of tempered glass, it is necessary to position and clamp the tempered glass, so a positioning and clamping device is needed.

[0003] The utility model patent with the publication number CN218137413U proposes a positioning and clamping device for tempered glass processing, which includes a moving module. The moving module includes a moving block. A hydraulic cylinder is fixedly installed on the lower surface of the moving block. A positioning frame is fixedly installed on the lower surface of the hydraulic cylinder. The positioning frame is threadedly connected with a threaded rod. A turntable is fixedly installed on the upper surface of the threaded rod. A bottom plate is fixedly installed on the lower surface of the threaded rod. A buffer spring is fixedly installed on the lower surface of the bottom plate. A contact plate is fixedly installed on the lower surface of the buffer spring.

[0004] When the above case works, the two ends of the tempered glass are respectively placed on the two positioning frames on both sides, and then the screw is rotated to make the buffer spring and the contact plate descend to clamp the tempered glass. However, in actual use, the tempered glass is usually rectangular or square. When the two ends of the tempered glass to be fixed are relatively wide, when only the centers of the two ends of the glass are fixed, the glass is likely to shake back and forth, making the clamping unstable and not convenient for work. And when the glass is fixed by the spring, since the spring is set singly, there is a possibility that the glass shakes horizontally when fixed by the spring. And after long-term work of a single spring, metal fatigue or other conditions are likely to occur, resulting in the device being difficult to continue working and reducing the practicability of the device.

[0005] Therefore, the utility model provides a positioning and clamping device for tempered glass processing to meet the requirements. Summary of the Utility Model

[0006] The utility model provides a positioning and clamping device for tempered glass processing, which can solve the problems in the prior art that when the two ends of the tempered glass to be fixed are relatively wide during actual work, the glass is likely to shake back and forth, making the clamping unstable, and when the glass is fixed by the spring, there is a possibility that the glass shakes horizontally, and after long-term work of a single spring, metal fatigue or other conditions are likely to occur, resulting in the device being difficult to continue working and reducing the practicability of the device.

[0007] To solve the above technical problems, the present utility model provides the following technical solutions:

[0008] A positioning and clamping device for processing tempered glass, comprising a main body. Both ends of the bottom of the main body are slidably connected with moving seats. Both ends of the bottom of the moving seats are fixedly connected with fixed seats. The center of the bottom of the fixed seat is fixedly connected with a limiting frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following describes in detail a positioning and clamping device for processing and treating tempered glass provided by the present utility model in conjunction with the accompanying drawings and specific embodiments; it should be noted here that, in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some well-known technologies, those skilled in the art can also adopt other alternative methods.

[0026] As Figures 1 to 4 shown, an embodiment of the utility model provides a positioning and clamping device for processing tempered glass, which includes a main body 1. Both ends of the bottom of the main body 1 are slidably connected with moving seats 2. Both ends of the bottom of the moving seats 2 are fixedly connected with fixed seats 3. The center of the bottom of the fixed seat 3 is fixedly connected with a limiting frame 4. The bottom end of the limiting frame 4 is rotatably connected with a toothed ring 5. The inner side of the toothed ring 5 is threadedly connected with a lifting column 6. The limiting frame 4 includes a limiting rod at the bottom end. The top end of the toothed ring 5 is provided with a limiting groove 13 adapted to the limiting rod. The outer side of the toothed ring 5 is engaged with a toothed belt 10. The toothed ring 5 is in transmission connection with another toothed ring 5 on the same side through the toothed belt 10. A bidirectional lead screw 14 is rotatably connected inside the main body 1. One side of the main body 1 is fixedly connected with a motor 15. One end of the bidirectional lead screw 14 penetrates out of the main body 1 and is fixedly connected with the output end of the motor 15. Both ends of the bidirectional lead screw 14 are respectively threadedly connected to the inner sides of the two moving seats 2.

[0027] Start the motor 15 to drive the bidirectional lead screw 14 to rotate, so that the two moving seats 2 move towards the center at the same time. Adjust the distance between the two moving seats 2 according to the size of the tempered glass, and place the four corners of the tempered glass on the inner sides of the four placing seats 7 respectively.

[0028] Through the layout of the four placing seats 7, the device can fix the four corners of the tempered glass at the same time, greatly enhancing the stability of the fixation. So that the tempered glass can maintain its original position and posture even when subjected to external impact or vibration during the processing, without shaking or shifting back and forth. And the toothed belt 10 connects the toothed rings 5 on both sides together to form a synchronous transmission system, thereby realizing the synchronous lifting of the lifting columns 6 on both sides. This not only simplifies the operation process, but also ensures the uniform distribution of the clamping force on both sides, avoiding the inclination or shaking of the tempered glass caused by improper unilateral operation.

[0029] As Figures 1 to 5As shown, there is a fixing component 8 which is used to fix the external tempered glass. The fixing component 8 is connected to the lifting column 6. A number of connecting blocks are fixedly connected to the outer side of the bottom of the fixing seat 3. The bottom of the connecting block is fixedly connected to a placing seat 7. The bottom end of the lifting column 6 penetrates and extends to the inside of the placing seat 7. The bottom of the fixing component 8 is fixedly connected to a pressing plate 9. A soft pad is fixedly connected to the bottom of the pressing plate 9. The fixing component 8 includes an upper plate 801 fixedly connected to the bottom of the lifting column 6. A number of fixing elastic pieces 802 are fixedly connected to the outer side of the bottom of the upper plate 801. A telescopic rod 804 is fixedly connected to the center of the bottom of the upper plate 801. The bottom of the telescopic rod 804 is fixedly connected to a lower plate 803. The fixing elastic pieces 802 are annularly distributed at the bottom of the upper plate 801 and are divided into two inner and outer circles. The number of the inner circle is four, and the number of the outer circle is eight. The fixing elastic pieces 802 are bent outward and stress holes are provided inside. The bottoms of the fixing elastic pieces 802 are all fixedly connected to the top of the lower plate 803. Sawteeth are distributed on the inner side of the toothed belt 10. A rotating shaft 11 is rotatably connected to the middle of the bottom side of the moving seat 2. A rotating toothed shaft 12 is fixedly connected to the bottom of the rotating shaft 11. The rotating toothed shaft 12 meshes with the middle of the inner side of the toothed belt 10. A rotating handle is fixedly connected to the bottom of the rotating toothed shaft 12.

[0030] Rotate the rotating toothed shafts 12 on both sides to drive the corresponding toothed belts 10 to rotate, so that the toothed ring 5 rotates. Drive the lifting column 6 to descend through threaded connection, and then drive the fixing component 8 and the pressing plate 9 to descend, gently contact and fix the tempered glass. As the lifting column 6 descends, the fixing elastic pieces 802 gradually bend and push the pressing plate 9 downward. Through the stress holes and elastic characteristics inside it, uniform clamping force is provided to ensure that the tempered glass will not move during the processing, and the clamping work is completed.

[0031] When the lifting column 6 drives the fixing component 8 to descend and the fixing elastic pieces 802 are gradually squeezed, they will deform uniformly around along the preset bending path. This deformation not only generates the necessary downward extrusion force to firmly fix the tempered glass in the working position, but also forms a surrounding force that expands around. This force distribution effectively cancels out the possible lateral impact force or vibration during the processing, preventing any tiny displacement of the tempered glass in the horizontal direction, thereby greatly improving the processing accuracy and the quality of the finished product; the layout of the fixing elastic pieces 802 also adopts the setting of two inner and outer circles, and each circle of elastic pieces is an independent individual structure, making the clamping force distribution more uniform. Whether it is the central area or the edge area of the tempered glass, it can be fully supported and fixed. Even if a certain elastic piece is damaged or worn, it will not affect the normal working state of other elastic pieces, nor will it affect the clamping effect of the entire fixing component 8, significantly extending the overall service life of the device.

[0032] Working principle provided by the present utility model: Start the motor 15 to drive the bidirectional lead screw 14 to rotate, so that the two moving seats 2 move towards the center simultaneously. Adjust the distance between the two moving seats 2 according to the size of the tempered glass. Place the four corners of the tempered glass inside the four placing seats 7 respectively. Rotate the rotating tooth shafts 12 on both sides to drive the corresponding toothed belts 10 to rotate, so that the toothed ring 5 rotates. Drive the lifting column 6 to descend through threaded connection, and then drive the fixing assembly 8 and the pressing plate 9 to descend, gently contacting and fixing the tempered glass. As the lifting column 6 descends, the fixing elastic piece 802 gradually bends and pushes the pressing plate 9 downward. Through the stress holes and elastic characteristics inside it, a uniform clamping force is provided to ensure that the tempered glass does not move during the processing, and the clamping work is completed.

[0033] The present utility model covers any substitutions, modifications, equivalent methods and solutions made on the essence and scope of the present utility model; in order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without the description of these details.

[0034] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
