Description

Technical Field

[0001] The utility model relates to the technical field of 3D glass measurement, in particular to a fixture used for 3D glass chamfering and body measurement. Background Art

[0002] 3D glass products, especially 3D glass with large curvature and irregular edges (such as VR glasses), will have chamfers and standoffs on the inner and outer edges. The inner chamfer, outer chamfer and standoffs are key parts when assembling 3D glass, and are related to whether the 3D glass product can be smoothly assembled with other parts. Therefore, the dimensions of the above-mentioned parts are subject to strict control standards. After the 3D glass product is processed, the 3D glass needs to be fixed on the fixture and the dimensions of the above-mentioned parts need to be inspected to eliminate products with unqualified dimensions.

[0003] At present, there are two common methods for measuring chamfers and angles of 3D glass in the industry. One is the angle block measurement method, which uses pads of different angles to align the 3D glass according to the position to be measured and measure it; the other is to use a motor to control the rotation of an automatic turntable to align the product fixed on the turntable for measurement. The former requires the replacement of angle blocks of different angles when collecting data at different angles. For 3D glass with large arcs and irregular shapes, at least 7 different angles need to be measured. Frequent replacement of angle blocks is extremely inconvenient, and the measurement efficiency of the product is low. The number of angle blocks involved is large, which is inconvenient to keep and easy to be confused. The latter requires the use of professional programming software to write the corresponding angle position program to control the rotation of the turntable. The operation is convenient, flexible and accurate. However, its use cost is extremely high, and it can only be installed on a dedicated machine. This measurement method is usually only used on mass-produced 3D glass production lines and is not suitable for the initial proofing stage. Its applicable scenarios are insufficient.

[0029] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0030] Please combine Figure 1-5The utility model discloses a fixture 10 for measuring chamfers and stand-offs of 3D glass. The fixture is mainly used to align the inner chamfers, outer chamfers, and stand-offs of large-arc 3D glass, and to measure the inner chamfers, outer chamfers, and stand-offs of 3D glass. The fixture includes a bracket base 100, a bracket insert 200 fixed on the bracket base 100, a product positioning block 300, and a product fixing block 400 that is detachably fixed on the product positioning block 300 and positions the product 20 to be measured. Specifically, two bracket inserts 200 are relatively arranged on the bracket base 100, and a swing clamping area is formed between the two bracket inserts 200. The bracket base 100 is used to support the remaining components, and the bracket insert 200 is used to provide a mounting portion for the product positioning block 300. The top surface of the bracket insert 200 is provided with a limiting notch 210 connected to the swing clamping area, and the limiting notch 210 is used to provide the rotation center of the product positioning block 300; the side surface of the bracket insert 200 is provided with at least one through hole 220 beside the limiting notch 210. The top surface of the product positioning block 300 is provided with a positioning groove 310, and the positioning groove 310 is used to provide a receiving or receiving area for the product 20 to be tested. The inner contour shape of the positioning groove 310 is adapted to the outer contour shape of the product 20 to be tested, so that after the product 20 to be tested is placed in the installation groove, the outer surface of the product 20 to be tested fits with the inner surface of the positioning groove 310, so that the positioning of the product 20 to be tested in the fixture is more accurate. Preferably, the positioning groove 310 of the product positioning block 300 can be formed by one-time processing using a CNC machine. Two limiting connection parts corresponding to two bracket inserts 200 are arranged on two opposite outer sides of the product positioning block 300, that is, when the product positioning block 300 is clamped on the bracket insert 200, each limiting connection part corresponds to one bracket insert 200. A rotating shaft 320 penetrating the limiting notch 210 is fixedly connected to the limiting connection part, and a plurality of insertion holes 330 are opened on the side of the rotating shaft 320 on the limiting connection part. When the product positioning block 300 is installed, it is rotatably arranged on the corresponding bracket insert 200 through the rotating shafts 320 on both sides thereof. Two product fixing blocks 400 are arranged on the top surface of the product positioning block 300 on both sides of the positioning groove 310. The product fixing blocks 400 are detachably connected to the product positioning block 300, and a crimping portion 410 is provided on the product fixing block 400, which protrudes toward the middle of the positioning groove 310 and presses the edge of the product 20 to be tested together with the edge of the positioning groove 310, so as to prevent the product 20 to be tested from falling off the product positioning block 300 during the rotation of the product positioning block 300. The product positioning block 300 is fixedly connected to the bracket insert 200 through the pin 500 penetrating the through hole 220 and any plug hole 330, that is, the two sides of the product positioning block 300 are respectively fixed to a corresponding bracket insert 200 through the pin 500, so as to realize the position limitation of the product positioning block 300.When it is necessary to adjust the angle of the product 20 to be tested in the product positioning block 300, it is only necessary to pull out the pin 500 from the socket 330, rotate the angle of the product positioning block 300 to a suitable position, and then insert the pin 500 into the corresponding socket 330 to achieve the position adjustment of the product 20 to be tested.

[0031] The above-mentioned fixture 10 for 3D glass chamfering and body measurement is different from the angle block fixture that needs to use multiple different angle blocks for measurement. It has a simple structure and is an integrated fixture, which is convenient to carry and store. When measuring data at different positions, the product positioning block 300 is rotated and the product positioning block 300 rotated to a preset angle is positioned using the pin 500, which can meet the needs of alignment and measurement of different parts of the product. The product angle alignment operation is simple, which improves the measurement efficiency of the product and has low cost of use. The fixture is not limited by the measuring machine and can be used on a machine with a large stroke or a machine with a small stroke, and can be used in both mass production and proofing. It has better flexibility and applicability for products in the initial proofing stage, reduces the proofing production cost in the proofing stage, and saves resources.

[0032] Please further combine Figure 1-3 The support base 100 includes two transverse connecting rods 110 arranged opposite to each other, a first longitudinal connecting rod 120 located on one side of the two transverse connecting rods 110 and fixedly connected to the two transverse connecting rods 110, and a second longitudinal connecting rod 130 located on the other side of the two transverse connecting rods 110 and fixedly connected to the two transverse connecting rods 110. A support insert 200 is fixed on the first longitudinal connecting rod 120, and another support insert 200 is fixed on the second longitudinal connecting rod 130. It can also be understood that the support base 100 is a square-shaped frame structure. In this embodiment, the support base 100 is designed as a square-shaped structure to avoid interference between the product positioning block 300 and the support base 100 during the rotation process. The area surrounded by the transverse connecting rod 110, the first longitudinal connecting rod 120 and the second longitudinal connecting rod 130 provides a larger swing range for the rotation of the product positioning block 300 to meet the angle adjustment requirements when measuring different products.

[0033] Further, in the present embodiment, the bottom surface of the first longitudinal connecting rod 120 is provided with a first clamping hole 121 and a second clamping hole 122 at intervals, and the top surface of the first longitudinal connecting rod 120 is provided with a third clamping hole 123; the bottom surface of the second longitudinal connecting rod 130 is provided with a fourth clamping hole 131 and a fifth clamping hole 132 at intervals, and the top surface of the second longitudinal connecting rod 130 is provided with a sixth clamping hole 133; the two ends of a transverse connecting rod 110 are respectively inserted into the first clamping hole 121 and the fourth clamping hole 131 to be screwed to the first longitudinal connecting rod 120 and the second longitudinal connecting rod 130 respectively; the two ends of another transverse connecting rod 110 are respectively inserted into the second clamping hole 122 and the fifth clamping hole 132 to be screwed to the first longitudinal connecting rod 120 and the second longitudinal connecting rod 130 respectively; a bracket insert 200 is inserted into the third clamping hole 123 and fixedly connected to the first longitudinal connecting rod 120, and another bracket insert 200 is inserted into the sixth clamping hole 133 and fixedly connected to the second longitudinal connecting rod 130. In this embodiment, by opening the first clamping hole 121, the second clamping hole 122, and the third clamping hole 123 on the first longitudinal connecting rod 120, and opening the fourth clamping hole 131, the fifth clamping hole 132 and the sixth clamping hole 133 on the second longitudinal connecting rod 130, the transverse connecting rod 110 and the bracket insert 200 can be pre-positioned to prevent the above-mentioned components from shifting during the assembly process of the clamp, thereby reducing the difficulty of assembling the clamp.

[0034] It should be noted that, in this embodiment, the transverse connecting rod 110, the first longitudinal connecting rod 120, the second longitudinal connecting rod 130, and the bracket insert 200 are respectively made of aluminum alloy materials. In this way, while ensuring the mechanical strength of the bracket base 100 and the bracket insert 200, the overall weight of the fixture is reduced, and the entire fixture is small and light, and is not limited by the measuring machine, and can be used on different measuring machines, such as two-dimensional machines, three-dimensional machines, roughness measuring machines, microscope machines, etc.

[0035] In addition, in order to improve the stability of the product positioning block 300 fixed on the bracket insert 200, in the present embodiment, a through hole 220 is provided on each side of the limiting notch 210 on the bracket insert 200, and a through hole 230 is opened below at least one side of the through hole 220. Similarly, a row of sockets 330 is provided on each side of the rotating shaft 320 on the limiting connection portion of the product positioning block 300, and each row of sockets 330 includes a plurality of sockets 330 arranged along the height direction of the bracket insert 200. In this way, after the product positioning block 300 is rotated to a preset angle, the product positioning block 300 can be positioned on the bracket insert 200 by respectively passing through the through holes 220 on both sides and inserted into the corresponding plug holes 330. The product positioning block 300 can also be positioned on the bracket insert 200 by passing through the through hole 230 and the through hole 220 on one side and inserting into the corresponding plug holes 330. This increases the connection area between the product positioning block 300 and the bracket insert 200, thereby improving the stability of the installation of the product positioning block 300.

[0036] Please combine Figure 1 as well as Figure 4-6 The top surface of the product positioning block 300 is provided with two installation notches 340 opposite to the notch edge of the positioning groove 310, and the product fixing block 400 is embedded in the installation notches 340 and is detachably connected to the product positioning block 300. In this embodiment, the product fixing block 400 is in a "7"-shaped structure, the crimping portion 410 constitutes the horizontal portion of the product fixing block 400, and the vertical portion of the product fixing block 400 is embedded in the installation notches 340 during assembly. In this way, while ensuring that the crimping portion 410 is located on the top surface of the product positioning block 300 to press the product 20 to be tested, the pre-positioning of the product fixing block 400 is achieved.

[0037] Furthermore, the product fixing block 400 is screw-connected or magnetically connected to the product positioning block 300. Preferably, in the present embodiment, the product fixing block 400 is magnetically connected to the product positioning block 300. Specifically, a first groove is provided in the installation notch 340, and a second groove corresponding to the first groove is provided at the bottom of the product fixing block 400. A first magnetic component 341 is embedded and fixed in the first groove, and a second magnetic component 420 magnetically connected to the first magnetic component 341 is embedded and fixed in the second groove. Both the first magnetic component 341 and the second magnetic component 420 are magnets. After being embedded in the first groove, the first magnetic component 341 is bonded to the inner surface of the first groove, and after being embedded in the second groove, the second magnetic component 420 is bonded to the inner surface of the second groove, so as to improve the stability of the first magnetic component 341 embedded in the first groove, and at the same time improve the stability of the second magnetic component 420 embedded in the second groove. During the clamping process of the product to be tested 20, it is only necessary to remove the product fixing block 400 from the installation notch 340 of the product positioning block 300 to take and place the product. Similarly, after the product is placed in the positioning groove 310, it is only necessary to embed the product fixing block 400 into the installation notch 340. The crimping portion 410 of the product fixing block 400 presses the product to be tested 20 under the magnetic attraction of the first magnetic part 341 and the second magnetic part 420 to fix the product, thereby reducing the difficulty of clamping the product and saving the time of product clamping.

[0038] In one embodiment, the hardness of the product positioning block 300 and the product fixing block 400 is respectively lower than the hardness of the product 20 to be tested. Preferably, the product positioning block 300 and the product fixing block 400 are respectively made of ABS material. By selecting a material with a hardness lower than the hardness of the product 20 to be tested to make the product positioning block 300 and the product fixing block 400, it is possible to avoid the product positioning block 300 and the product fixing block 400 from colliding or scratching the product during the product clamping process. The fixture of this embodiment can not only be used for chamfering and stand-up position measurement of 3D glass products, but is also suitable for all products with large curvatures that require measurement of inner chamfers, outer chamfers and stand-up positions, such as plastic products and ceramic products.

[0039] Please combine Figure 7-11 During the product measurement process, first put the fixture on the workbench of the measuring machine (first stage); then remove the product fixing blocks 400 from both sides of the product positioning block 300 (second stage); load the product 20 to be measured into the positioning groove 310, and embed the product fixing block 400 into the installation notch 340 to press the edge of the product (third stage); pull out the pin 500, rotate the product positioning block 300 to the angle position to be measured, and then insert the pin 500 into the corresponding socket 330 to fix the product positioning block 300, and then measure (fourth stage); after the measurement is completed, remove the product fixing blocks 400 on both sides of the product positioning block 300, and remove the product (fifth stage), that is, complete one measurement of the product.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
