Description

Technical Field

[0001] The utility model relates to the technical field of glass cutting, and more specifically, the utility model relates to a fixing device for a glass substrate cutting tool. Background Art

[0002] A glass substrate is an extremely flat thin glass sheet, which is one of the key basic materials in the flat panel display industry (including liquid crystal displays, OLED displays, etc.). On a glass production line, the annealed glass liquid continuously and uniformly flows downward, and then a forming device is used to merge the naturally downward overflowing glass liquid into an ultra-thin glass ribbon to obtain an ultra-thin glass original sheet. After that, a transverse cutting device is needed for transverse cutting, and then a glass longitudinal cutting device is also needed for preliminary longitudinal cutting. After transverse cutting and longitudinal cutting are completed, fine cutting is still required according to the specific dimensions required by customers. Therefore, in the production process of a glass substrate, the glass substrate needs to be cut multiple times.

[0003] In the process of multiple glass cuttings, the role of the cutting tool is particularly important. In the existing fixing device for a glass substrate cutting tool, the tool head is usually directly inserted into the tool holder. There is a groove on the tool head (as shown in Figure 1 ), and a convex ring is provided in the tool holder. The groove and the convex ring are adaptively inserted, or the tool head and the tool holder are fixed by a threaded connection method (as shown in Figure 2 ). These two tool fixing methods have the following deficiencies: First, the tool positioning is inaccurate. When the tool head is directly inserted into the tool or the tool head is threadedly connected to the tool holder, it is very easy for the position of the blade on the tool head not to be consistent with the moving cutting direction of the tool, so it is very easy for the cutting position of the glass substrate to deviate, and it does not cut along the predetermined direction, resulting in diagonal cutting; Second, the tool installation is unstable. Just using the above fixing method, it is very easy for the tool head to rotate and loosen and fall off, which affects the cutting effect, is not conducive to the smooth progress of the glass substrate cutting work, and reduces the cutting efficiency. Content of the Utility Model

[0004] In order to solve the above problems of the prior art, the utility model provides a fixing device for a glass substrate cutting tool, which uses a tensioning and positioning component to position and fix the tool head, and then under the action of a clamping component, the position of the cutting tool head is limited, solving the problem of inaccurate tool positioning and enhancing the stability of the tool during operation.

[0005] According to one aspect of the present utility model, there is provided a fixing device for a glass substrate cutting tool, including a tool head and a tool holder. The tool head is inserted into the tool holder through an insertion rod. An arc-shaped clamping groove and a rectangular clamping groove are formed on the tool head. The arc-shaped clamping groove and the rectangular clamping groove are on the same horizontal plane, and both ends of the arc-shaped clamping groove communicate with both ends of the rectangular clamping groove. A clamping component for clamping the tool head is clamped on the arc-shaped clamping groove, and a tensioning and positioning component for tensioning and positioning the tool head is clamped on the rectangular clamping groove.

[0006] With this solution, first, the tool head is clamped with the tensioning and positioning component, and then the tool head is inserted into the tool holder. The setting of the tensioning and positioning component has a good positioning effect, preventing the installation position of the tool head from deviating. At the same time, under the action of the tensioning and positioning component, the tool head can be further fixed. Then, under the action of the clamping component, the tool head is further clamped, so as to maximally avoid the problems of the tool head rotating or loosening during the process of cutting the glass substrate. The operation method is simple, ensuring the smooth progress of the glass substrate cutting work; the setting of the rectangular clamping groove can prevent the tool from rotating during the cutting operation.

[0007] Preferably, the tensioning and positioning component includes a fixing frame and a spring. The fixing frame is elastically slidably connected to the tool holder through the spring, and the bottom of the fixing frame is clamped with the rectangular clamping groove.

[0008] With this solution, when installing the tool head, pull the fixing frame downward to clamp the rectangular clamping groove on the tool head with the fixing frame, and then release the fixing frame. The insertion rod at the top of the tool head just inserts into the tool holder. The setting of the spring can apply an upward pulling force to the tool head, so as to better position and fix the tool head.

[0009] Preferably, the clamping component includes a fixing rod, a torsion spring and a connecting frame. The fixing rod is vertically and fixedly installed on the tool holder. The connecting frame is rotatably connected to the fixing rod through the torsion spring, and the bottom of the connecting frame is clamped with the arc-shaped clamping groove.

[0010] With this solution, after the tool head is installed, under the action of the torsion spring, pull the connecting frame outward. The connecting frame rotates around the fixing rod, so that the connecting frame is clamped with the arc-shaped clamping groove on the tool head, thus realizing the clamping of the tool head. The operation method is simple and highly practical.

[0011] Preferably, both the connecting frame and the fixing frame are of L-shaped structures.

[0012] With this solution, since the arc-shaped clamping groove and the rectangular clamping groove are on the same horizontal plane, the two L-shaped connecting frames and fixing frames can meet the clamping requirements of the arc-shaped clamping groove and the rectangular clamping groove, thus realizing the fixation of the tool position.

[0013] Preferably, a convex block is provided at the end of the bottom of the connecting frame, a groove is formed at the end of the bottom of the fixing frame, and the convex block is adaptively inserted into the groove.

[0014] With this solution, the convex block on the connecting frame is adaptively inserted into the groove on the fixing frame, which can fix the fixing frame and the connecting frame together, can maximize the clamping and fixing work of the tool head, enhance the stability during the cutting process of the tool head, and improve the cutting efficiency.

[0015] Preferably, the convex block is of a conical structure.

[0016] With this solution, the conical structure can make it more convenient for the convex block to be inserted into the groove to achieve quick clamping.

[0017] Preferably, the spring is fixedly installed inside the tool holder, the top of the fixing frame is fixedly connected to the bottom of the spring, and the height of the fixing frame inside the tool holder is higher than the height of the insertion rod.

[0018] With this solution, the height of the fixing frame inside the tool holder is higher than the height of the insertion rod. This can not only limit the position of the tool head during use to prevent the tool head from rotating due to the fixing frame detaching from the tool holder, but also avoid the fixing frame detaching from the tool holder when the tool head needs to be replaced, without the need to reinsert the fixing frame into the tool holder, thus improving the subsequent tool head replacement progress.

[0019] The technical effect of the present utility model is that this glass substrate cutting tool fixing device can not only achieve rapid positioning of the tool head installation, prevent deviation in the installation position of the tool head, but also can maximize the clamping and fixing of the tool head, enhance the stability during the cutting process of the tool head, improve the cutting efficiency of the glass substrate, and ensure the smooth progress of the cutting work.

[0033] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0034] Embodiment

[0035] Such as Figures 3 to 6As shown in the figure, the glass substrate cutting tool fixing device in this embodiment includes a tool tip 1 and a tool holder 2. The tool tip 1 is inserted into the tool holder 2 through an insertion rod 9. An arc-shaped clamping groove 3 and a rectangular clamping groove 4 are formed on the tool tip 1. The setting of the rectangular clamping groove 4 can prevent the tool from rotating during the cutting operation. The arc-shaped clamping groove 3 and the rectangular clamping groove 4 are located on the same horizontal plane. The two ends of the arc-shaped clamping groove 3 are connected to the two ends of the rectangular clamping groove 4. A clamping component 5 for clamping the tool tip 1 is clamped on the arc-shaped clamping groove 3, and a tensioning and positioning component 6 for tensioning and positioning the tool tip 1 is clamped on the rectangular clamping groove 4. The setting of the tensioning and positioning component 6 has a good positioning effect.

[0036] First, connect the tool tip 1 with the tensioning and positioning component 6, and then insert the tool tip 1 into the tool holder 2 to prevent the installation position of the tool tip 1 from deviating. At the same time, under the action of the tensioning and positioning component 6, the tool tip 1 can be further fixed. Then, under the action of the clamping component 5, the tool tip 1 can be further clamped, so as to maximize the avoidance of problems such as the tool tip rotating in circles or the tool tip loosening during the process of cutting the glass substrate. The operation method is simple, ensuring the smooth progress of the glass substrate cutting work.

[0037] Further, the tensioning and positioning component 6 includes a fixing frame 61 and a spring 62. The setting of the spring 62 can apply an upward pulling force to the tool tip 1, so as to better position and fix the tool tip 1. The fixing frame 61 is elastically slidably connected to the tool holder 2 through the spring 62, and the bottom of the fixing frame 61 is clamped with the rectangular clamping groove 4.

[0038] When installing the tool tip 1, pull down the fixing frame 61 to clamp the rectangular clamping groove 4 on the tool tip 1 with the fixing frame 61, and then release the fixing frame 61. The insertion rod 9 at the top of the tool tip 1 is just inserted into the tool holder 2.

[0039] Further, the clamping component 5 includes a fixing rod 51, a torsion spring 52 and a connecting frame 53. The fixing rod 51 is vertically and fixedly installed on the tool holder 2. The connecting frame 53 is rotatably connected to the fixing rod 51 through the torsion spring 52, and the bottom of the connecting frame 53 is clamped with the arc-shaped clamping groove 3.

[0040] After the tool tip 1 is installed, under the action of the torsion spring 52, pull the connecting frame 53 outwards. The connecting frame 53 rotates around the fixing rod 51, so that the connecting frame 53 is clamped with the arc-shaped clamping groove 3 on the tool tip 1, thus realizing the clamping of the tool tip 1. The operation method is simple and highly practical.

[0041] Further, both the connecting frame 53 and the fixing frame 61 are of L-shaped structures.

[0042] Since the arc-shaped card slot 3 and the rectangular card slot 4 are on the same horizontal plane, the connecting frames 53 and the fixing frames 61 with two L-shaped structures can meet the requirements of the clamping work for the arc-shaped card slot 3 and the rectangular card slot 4, thereby realizing the fixation of the tool position.

[0043] Furthermore, a convex block 7 is provided at the end of the bottom of the connecting frame 53, and a groove 8 is opened at the end of the bottom of the fixing frame 61, and the convex block 7 is adaptively inserted into the groove 8.

[0044] The convex block 7 on the connecting frame 53 is adaptively inserted into the groove 8 on the fixing frame 61, which can fix the fixing frame 61 and the connecting frame 53 together, can maximize the clamping and fixing work of the tool head 1, enhance the stability during the cutting process of the tool head, and improve the cutting efficiency.

[0045] Furthermore, the convex block 7 is of a conical structure, which can make it more convenient for the convex block 7 to be inserted into the groove 8 to achieve rapid clamping.

[0046] Furthermore, the spring 62 is fixedly installed inside the tool holder 2, the top of the fixing frame 61 is fixedly connected to the bottom of the spring 62, and the height of the fixing frame 61 inside the tool holder 2 is higher than the height of the insertion rod 9.

[0047] The height of the fixing frame 61 inside the tool holder 2 is higher than the height of the insertion rod 9. This can not only limit the position of the tool head 1 during use to prevent the tool head 1 from rotating due to the fixing frame 61 detaching from the tool holder 2, but also avoid the fixing frame 61 detaching from the tool holder 2 when the tool head 1 needs to be replaced, without the need to re-insert the fixing frame 61 into the tool holder 1, improving the subsequent tool head replacement progress.

[0048] Furthermore, the overall length of the arc-shaped card slot 3 is less than the overall length of the rectangular card slot 4, which can better complete the clamping operation of the connecting frame 53 and is more practical.

[0049] The working principle of this embodiment is as follows:

[0050] When the tool head 1 needs to be installed or replaced, pull down the fixing frame 61. The fixing frame 61 is adaptively clamped with the rectangular card slot 4 on the tool head 1. Then release the fixing frame 61. The tool head 1 moves upward under the action of the spring 62, so that the insertion rod 9 on the tool head 1 is inserted into the tool holder 2. Synchronously rotate the connecting frame 53. The connecting frame 53 rotates around the fixed rod 51 under the action of the torsion spring 52. When the tool head 1 is inserted into the tool holder 2, lower the connecting frame 53, so that the bottom of the connecting frame 53 is clamped with the arc-shaped card slot 3, and the convex block 7 on the connecting frame 53 is adaptively inserted into the groove 8 on the fixing frame 61, thereby maximizing the fixation of the tool head and enhancing the stability during the cutting process.

[0051] The technical effect of the embodiment of the present utility model is that this fixing device for the glass substrate cutting tool can not only achieve rapid positioning of the cutter head installation, prevent deviation in the installation position of the cutter head, but also can clamp and fix the cutter head to the greatest extent, enhance the stability of the cutter head during the cutting process, improve the efficiency of glass substrate cutting, and ensure the smooth progress of the cutting work.

[0052] Although some specific embodiments of the present utility model have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and not for limiting the scope of the present utility model. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present utility model. The scope of the present utility model is defined by the appended claims.
