Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and more specifically, to a positioning and cutting device for glass processing. Background Technology

[0002] In the entire glass processing workflow, the cutting process undoubtedly plays a crucial role. As a core process that connects the preceding and following steps, the precision of the cutting directly determines whether subsequent processing steps can proceed smoothly and ultimately affects the quality of the finished product. Specifically, dimensional errors in glass not only affect the assembly and matching degree between various parts of the product, making it difficult for them to fit perfectly, but also significantly reduce the overall pass rate of the entire batch of products, resulting in unnecessary material waste and increased costs. Therefore, adopting an efficient and precise positioning and cutting device is not only a necessary guarantee for improving production quality, but also an important cornerstone for maintaining the stable and efficient operation of the entire production line.

[0003] In existing technologies, common glass cutting and positioning methods mostly rely on manual adjustment of the glass position followed by successive fixation of the sides and surface compaction. This process is not only cumbersome and time-consuming, but manual positioning is also prone to errors, making it difficult to guarantee accuracy during repeated positioning. Consequently, the dimensional consistency of glass products cut in the same batch is poor, resulting in a high defect rate. How to invent a positioning and cutting device for glass processing to solve these problems has become an urgent issue for those skilled in the art. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a positioning and cutting device for glass processing, which aims to solve the problem that the common glass cutting positioning mostly relies on manual adjustment of the glass position first, and then fixing and pressing the sides and surface one by one. Not only are the operation steps cumbersome and time-consuming, but manual positioning is also prone to errors. When repositioning, it is difficult to guarantee the accuracy, resulting in poor dimensional consistency of glass products cut in the same batch and a high defect rate.

[0005] This invention is implemented as follows: This invention provides a positioning and cutting device for glass processing, including a cutting device and a positioning component disposed on the cutting device, wherein the cutting device includes a cutting table and a cutting component; The positioning component is installed on the upper end of the cutting component. The positioning component includes a fixing plate, a side plate, a slide rod, a return spring, a cylinder, a diagonal rod, a positioning rod, a connecting plate, a diagonal block, a fixing rod, and a positioning pad.

[0006] Preferably, the fixing plate is fixed to the side wall of the cutting assembly by bolts, the two side plates are symmetrically fixed at both ends of the fixing plate, the two sliding rods are symmetrically fixed between the side plates, and the two ends of the sliding rods are respectively fixedly connected to the side of the side plate.

[0007] Preferably, two return springs are respectively installed at different ends of two slide rods, the cylinder is installed at the upper end of the fixed plate, and the telescopic end of the cylinder is slidably connected to the inner wall of the fixed plate.

[0008] Preferably, one end of the inclined rod is fixedly connected to one end of the positioning rod, the side wall of the inclined rod has a through sliding hole, the inner wall of the sliding hole is slidably connected to the outer wall of the sliding rod, and the two ends of the return spring are fixedly connected to the side plate and one end of the inclined rod, respectively.

[0009] Preferably, the two inclined rods are symmetrically arranged on both sides of the cylinder extension end, the upper end of the connecting plate is fixedly connected to the cylinder extension end, and the two inclined blocks are symmetrically arranged and fixed to the lower end of the connecting plate with their inclined surfaces facing opposite directions.

[0010] By adopting the above technical solution, while the cylinder piston rod moves steadily downward, it simultaneously pushes the top connecting plate to move smoothly downward along a precise vertical track. Two symmetrically distributed inclined blocks fixed to this connecting plate also descend smoothly and synchronously. These two inclined blocks, through their precision-machined inclined mating surfaces, act on the inclined rods located on both sides of the device. Under the action of their inclined surfaces, the two inclined rods receive a stable and precise lateral driving force. They slide smoothly and precisely towards the center of the device along the fixed sliding rod axis. During this process, cleverly designed balls roll efficiently between the mating surfaces of the inclined blocks and inclined rods, which significantly reduces the sliding friction resistance generated during their relative movement. This design not only significantly reduces wear on the mating surfaces caused by long-term friction, effectively avoiding the problem of decreased fitting accuracy due to wear accumulation, but also fundamentally improves the reliability and service life of the entire mechanical device.

[0011] Preferably, the lower end face of the inclined block is parallel to the upper end inclined face of the inclined rod, and the lower end face of the inclined block is provided with a plurality of equidistant rolling grooves. The inner wall of the rolling groove is rolledly connected with a ball, and the outer wall of the ball is rolledly connected to the upper end inclined face of the inclined rod.

[0012] Preferably, the upper end of the fixing rod is fixedly connected to the lower end of the connecting plate, a buffer spring is provided at the lower end of the fixing rod, the two ends of the buffer spring are fixedly connected to the lower end of the fixing rod and the upper end of the positioning pad respectively, and a sliding sleeve is fixedly connected to the upper end of the positioning pad, the inner wall of the sliding sleeve and the outer wall of the fixing rod are slidably connected.

[0013] By adopting the above technical solution, when the positioning pad has already pressed the glass but the positioning rod has not yet completed the side clamping, the cylinder will continue to push the connecting plate downward. The buffer spring can maintain the positioning pad's pressed state while cooperating with the positioning rod to continue the clamping action until the positioning rods on both sides complete the side clamping and positioning of the glass. This achieves the simultaneous completion of the two processes of horizontal positioning and vertical pressing, eliminating the need for separate operations and effectively improving the processing efficiency of positioning and cutting. After processing is completed, the cylinder piston rod retracts, the reset spring pushes the inclined rod to reset, and the buffer spring simultaneously pushes the positioning pad to lift, allowing the finished glass product to be easily removed. This integrated linkage positioning structure can simultaneously complete the horizontal positioning and vertical pressing of the glass, preventing the glass from shifting during the cutting process and effectively improving the accuracy and processing safety of glass cutting.

[0014] The beneficial effects of this invention are: While using a cylinder to drive the positioning pad downwards to vertically position the glass, a mechanical structure drives positioning rods on both sides to position the glass sides, thus directly completing the positioning of multiple positions on the glass. Through the linked mechanical structure, the two key steps of side positioning and surface pressing before glass cutting are combined into one and completed synchronously and automatically. This not only ensures high precision and repeatability of positioning, avoiding errors from manual operation, but also simplifies the operation process and improves work efficiency. Ultimately, the stable and accurate positioning lays a solid foundation for the subsequent cutting process, thereby significantly improving the overall processing quality and consistency of the glass cutting product.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example, refer to Figures 1-7 A positioning and cutting device for glass processing includes a cutting device 1 and a positioning component 2 disposed on the cutting device 1. The cutting device 1 includes a cutting table 11 and a cutting component 12. The positioning component 2 is installed on the upper end of the cutting component 12. The positioning component 2 includes a fixing plate 21, a side plate 22, a slide rod 23, a return spring 24, a cylinder 25, a diagonal rod 3, a positioning rod 31, a connecting plate 4, a diagonal block 41, a fixing rod 43, and a positioning pad 46.

[0020] Furthermore; the fixing plate 21 is fixed to the side wall of the cutting assembly 12 by bolts, two side plates 22 are symmetrically fixed at both ends of the fixing plate 21, two sliding rods 23 are symmetrically fixed between the side plates 22, and the two ends of the sliding rods 23 are respectively fixedly connected to the side of the side plate 22. Two return springs 24 are respectively installed at different ends of the two sliding rods 23. The cylinder 25 is installed on the upper end of the fixing plate 21, and the telescopic end of the cylinder 25 is slidably connected to the inner wall of the fixing plate 21. One end of the inclined rod 3 is fixedly connected to one end of the positioning rod 31. A penetrating sliding hole 32 is opened on the side wall of the inclined rod 3, and the inner wall of the sliding hole 32 is slidably connected to the outer wall of the sliding rod 23. The two ends of the return springs 24 are respectively fixedly connected to the side plate 22 and one end of the inclined rod 3. The two inclined rods 3 are symmetrically arranged on the cylinder 21. On both sides of the telescopic end, the upper end of the connecting plate 4 and the telescopic end of the cylinder 25 are fixedly connected. Two inclined blocks 41 are symmetrically arranged and fixed to the lower end of the connecting plate 4 with their inclined surfaces facing opposite directions. The lower end face of the inclined block 41 is parallel to the upper inclined surface of the inclined rod 3. Multiple equidistant rolling grooves 411 are opened on the lower end face of the inclined block 41. The inner wall of the rolling groove 411 is rolled with a ball 42. The outer wall of the ball 42 is rolled with the upper inclined surface of the inclined rod 3. The upper end of the fixed rod 43 is fixedly connected to the lower end face of the connecting plate 4. The lower end of the fixed rod 43 is provided with a buffer spring 44. The two ends of the buffer spring 44 are fixedly connected to the lower end of the fixed rod 43 and the upper end of the positioning pad 46, respectively. The upper end of the positioning pad 46 is fixedly connected with a sliding sleeve 45. The inner wall of the sliding sleeve 45 is slidably connected to the outer wall of the fixed rod 43.

[0021] It should be noted that: In use, first place the glass to be processed stably on the cutting table 11, then the operator moves the cutting component 12 to precisely align it with the starting point of the preset cutting path (the subsequent cutting of the glass by the cutting component 12 is a conventional cutting technique, which will not be described in detail here). After the preparation is complete, start the cylinder 25. The piston rod of the cylinder 25 extends, and the connecting plate 4 will drive the vertically installed fixing rod 43 to descend together. The positioning pad 46 fixed at the bottom of the fixing rod 43 will first gently contact the upper surface of the glass. As the cylinder 25 continues to apply pressure, the buffer spring 44 connected to the positioning pad 46 is gradually compressed. This structure provides flexible buffer protection for the glass to avoid damage caused by hard impacts, and can also firmly press the glass onto the cutting table 11 through the controllable pressure continuously output by the spring. On the table, vertical positioning and clamping are completed. At the same time as the piston rod of cylinder 25 moves down, it pushes the connecting plate 4 above to move down smoothly in the vertical direction. The two inclined blocks 41 fixedly connected to the connecting plate 4 also descend synchronously. The inclined blocks 41 act on the inclined rods 3 on both sides through the inclined mating surface, forcing the two inclined rods 3 to slide smoothly and accurately towards the center along the axis of the fixed slide rod 23. At the same time, the ball bearing 42 can greatly reduce the sliding friction between the inclined blocks 41 and the inclined rods 3, avoid long-term wear of the inclined surface leading to a decrease in the fitting accuracy, and improve the service life of the device. When the inclined rods 3 slide towards each other, the two positioning rods 31 move closer to each other synchronously. This opposite movement drives the two positioning rods 31 installed at the ends of the inclined rods 3 to move closer to each other and firmly clamp them from both sides of the glass, completing the side positioning in the horizontal direction. Furthermore, when the positioning pad 46 has fully pressed against the glass surface, but the positioning rod 31 has not yet fully clamped the side, the cylinder 25 will continue to push the connecting plate 4 downward. At this time, the buffer spring 44 can maintain the stable pressing state of the positioning pad 46 and work with the positioning rod 31 to complete the subsequent clamping action until the positioning rods 31 on both sides accurately complete the clamping and positioning of the glass side. This process realizes that the horizontal positioning and vertical pressing operations of the glass are carried out simultaneously without the need for separate steps, thereby significantly improving the processing efficiency of the entire positioning and cutting process. After the processing is completed, the piston rod of the cylinder 25 actively retracts, and the reset spring 24 pushes the inclined rod 3 back to the initial position. The buffer spring 44 also pushes the positioning pad 46 to lift off the glass surface, so that the finished glass product can be easily taken out. This integrated linkage positioning structure can simultaneously complete the horizontal positioning and vertical pressing of the glass, effectively avoiding the displacement that may occur during the cutting process. This not only improves the cutting accuracy, but also enhances the safety and reliability of the entire processing process. This positioning device, through its ingeniously linked mechanical structure, combines the two key steps of side positioning and surface clamping before glass cutting into one, and achieves synchronous automatic completion. This not only ensures high precision and repeatability of positioning, avoiding errors from manual operation, but also simplifies the operation process and improves work efficiency. Ultimately, the stable and accurate positioning lays a solid foundation for subsequent cutting processes, thereby significantly improving the overall processing quality and consistency of the glass cutting products.

[0022] The working principle of this positioning and cutting device for glass processing: In use, the glass to be processed is placed on the cutting table 11. The operator moves the cutting component 12 to align with the starting point of the preset cutting path, and then activates the cylinder 25. The piston rod of the cylinder 25 extends, and the connecting plate 4 drives the fixed rod 43 to descend. The bottom positioning pad 46 contacts the upper surface of the glass, and the buffer spring 44 is gradually compressed, which protects the glass from damage and presses the glass firmly onto the cutting table 11 through controllable pressure, completing the vertical positioning and clamping. At the same time, the piston rod moves down, pushing the connecting plate 4 to move vertically downward, and the inclined block 41 descends synchronously, acting on the inclined rod 3 to make it slide towards the center along the fixed slide rod 23. The ball bearing 42 reduces friction and improves the life of the device. When the inclined rod 3 slides, the positioning rod 31 moves closer and clamps the glass from both sides, completing the horizontal side positioning. If the positioning pad 46 is pressed but the positioning rod 31 has not completed the side clamping, the cylinder 25 continues to push the connecting plate 4, and the buffer spring 44 cooperates with the positioning rod 31 to complete the clamping, realizing the synchronization of horizontal positioning and vertical clamping, and improving processing efficiency. After processing, the piston rod of cylinder 25 retracts, the return spring 24 resets the inclined rod 3, the buffer spring 44 lifts the positioning pad 46, and the finished glass product is removed. This integrated linkage positioning structure can simultaneously complete horizontal positioning and vertical clamping, avoid glass displacement, and improve cutting accuracy and processing safety.

[0023] It should be noted that the specific model and specifications of the cylinder need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
