[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings below. Typical embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.
[0025] refer to Figure 1 The glass off-line clamping fixture of this embodiment includes a profiling base 1, an upper cover plate 2, an elastic pressure block assembly 4, and a rotating shaft 5. The function of the profiling base 1 is to position the glass to be clamped and perform profiling positioning on the glass. The function of the upper cover plate 2 is to press the glass and quickly install the off-line fixture on the machine. The elastic pressure block assembly 4 is fixed to the bottom of the upper cover plate 2 through the rotating shaft 5. The rotating elastic pressure block assembly 4 forms an elastic force on the profiling base 1, and the profiling base 1 and the upper cover plate 2 press the glass to fix it.
[0026] The elastic pressure block assembly 4 can rotate around the rotating shaft 5, and a pressure block through hole 11 for the elastic pressure block assembly 4 to pass through is opened on the contour base 1. The top of the elastic pressure block assembly 4 has an elastic component 43 that elastically expands and contracts in the vertical direction. The upper cover plate 2 is located above the contour base 1, and the elastic pressure block assembly 4 passes through the pressure block through hole 11 and then rotates to the bottom of the contour base 1 and elastically abuts against the elastic component 43 up and down, so that the upper cover plate 2 and the contour base 1 clamp the glass up and down.
[0027] More specifically, refer to Figure 2-3, the upper cover plate 2 and the profiling base 1 are respectively provided with a profiling upper positioning groove 22 and a profiling lower positioning groove 12 for positioning the glass above and below. The shapes of the profiling upper positioning groove 22 and the profiling lower positioning groove 12 are determined according to the shape of the glass. In this embodiment, because the circular ring glass is clamped, the profiling upper positioning groove 22 and the profiling lower positioning groove 12 are also circular to match the shape of the glass. In this embodiment, two profiling upper positioning grooves 22 are arranged on the upper cover plate 2, and the two profiling upper positioning grooves 22 are arranged in a row along the length direction of the upper cover plate 2. One profiling lower positioning groove 12 is arranged on the profiling base 1. Therefore, in this embodiment, one upper cover plate 2 cooperates with two profiling bases 1. Of course, it is understandable that the number of the contoured upper positioning grooves 22 of the upper cover plate 2 and the contoured lower positioning grooves 12 on the contoured base 1 is not limited thereto, and they can be one or more, that is, one upper cover plate 2 can cooperate with one contoured base 1, one upper cover plate 2 can cooperate with multiple contoured bases 1, or multiple upper cover plates 2 can cooperate with one contoured base 1.
[0028] refer to Figure 4-5 The elastic pressure block assembly 4 includes a rectangular block-shaped pressure block 41, an elastic column 42, and an elastic component 43. The pressure block 41 is installed at the bottom of the upper cover plate 2 through a rotating shaft 5. The top of the rotating shaft 5 passes through the upper cover plate 2 from the bottom and is threadedly connected and locked with the upper cover plate 2. The pressure block 41 is rotatably mounted outside the rotating shaft 5. The elastic component 43 is installed on the top of the pressure block 41. The pressure block through hole 11 matches the pressure block 41.
[0029] Each pressing block 41 is provided with a plurality of elastic components 43, and the plurality of elastic components 43 are distributed around the rotating shaft 5. Specifically, in this embodiment, each pressing block 41 is provided with two elastic components 43, which are distributed on both sides of the rotating shaft 5. In fact, the number of elastic components 43 can be one or more. The elastic component 43 includes a spring, a pin, and a ball plunger. Specifically, in this embodiment, the ball plunger has a ball head, and the ball head of the ball plunger provides an upward elastic force on the contoured base 1 when clamping the glass. Figure 4 As shown, two vertically extending through holes are provided at the upper end of the pressing block 41 to install the ball plunger, which is inserted into the through holes and adjusted to a suitable elastic position, and then fixed by a screw 45, which is screwed in from the front or back of the pressing block 41 to tighten the ball plunger. The top of the pressing block 41 is at a certain distance from the bottom of the upper cover plate 2, and the distance allows the pressing block 41 to pass through the pressing block through hole 11 and then rotate to abut against the bottom surface of the contoured base 1.
[0030] A plurality of elastic columns 42 are installed at the same height in the pressing block 41, which are distributed around the rotating shaft 5 and elastically extend and contract along the radial direction of the rotating shaft 5. The elastic columns 42 can be ball plungers. The side wall of the rotating shaft 5 is provided with a plurality of spherical grooves 51 distributed around the rotating shaft 5 and matching the elastic columns 42 at the same height. The pressing block 41 can drive the elastic columns 42 to disengage from the currently inserted spherical grooves 51 and rotate to be inserted into other spherical grooves 51 by rotation. In this embodiment, four spherical grooves 51 are provided on the side wall of the rotating shaft 5. The four spherical grooves 51 are evenly distributed in the front, back, left and right of the rotating shaft 5, and two adjacent spherical grooves 51 form an angle of 90°. Two opposite ball plungers are arranged in the pressing block 41. The function of the two ball plungers is to connect the rotating shaft 5 with the pressing block 41. The pressing block 41 is connected and stuck in the spherical grooves 51 of the rotating shaft 5 through the two ball plungers. Since the ball plungers have elastic force, the pressing block 41 can be bent and rotated by 90°. like Figure 4 As shown, a horizontally extending through hole is provided at each of the left and right ends of the pressing block 41 to install a ball plunger, which is inserted into the through hole and adjusted to a suitable elastic position, and then fixed by a base screw 44, which is screwed into the bottom of the pressing block 41 to tighten the ball plunger. Of course, in theory, the number of spherical grooves 51 and the number of ball plungers are not limited to this.
[0031] There are multiple elastic pressure block components 4, and the number of pressure block through holes 11 is consistent with the number of elastic pressure block components 4. Multiple elastic pressure block components 4 are distributed around the contoured upper positioning groove 22, and multiple pressure block through holes 11 are distributed around the contoured lower positioning groove 12. The elastic pressure block components 4 and the pressure block through holes 11 are arranged vertically opposite to each other. In this embodiment, there are four elastic pressure block components 4 and pressure block through holes 11, which are respectively at an angle of 90°.
[0032] Combination Figure 1-3 , continue to refer to Figure 6-7 The upper cover plate 2 and the contour base 1 are both roughly rectangular. The length of the upper cover plate 2 is greater than the length of the contour base 1 because two contour upper positioning grooves 22 are provided on the upper cover plate 2. The width of the upper cover plate 2 is slightly greater than the width of the contour base 1. Figure 6 The upper cover plate 2 is provided with gourd slots 21 on both sides beyond the profiling base 1 for hanging on the machine platform 8. Specifically, the upper cover plate 2 includes a main body portion having a width equivalent to that of the profiling base 1 and a bending portion connected to both long sides of the main body portion and bent downward, and the gourd slots 21 are provided on the bending portion. A gourd slot 21 is provided at each end of each bending portion, and there are four gourd slots 21 in total.
[0033] refer to Figure 7The machine platform 8 includes a plurality of vertically arranged support plates 81, and screws 6 are vertically installed on the outer side of the support plates 81, and spring washers 7 are mounted on the screws 6. The large circle diameter of the gourd slot 21 is larger than the diameter of the spring washers 7, and the spring washers 7 can directly pass through the large circle of the gourd slot 21. The small circle diameter of the gourd slot 21 is smaller than the diameter of the spring washers 7, and the spring washers 7 are stuck here. The small circle part of the gourd slot 21 is raised relative to the large circle part to form a step so that the spring washers 7 move from the large circle to the small circle to form an elastic force to clamp the support plate 81.
[0034] refer to Figure 7 The usage process of this embodiment is as follows: Figure 7 In (a), first, the glass is placed on the contoured base 1 of the fixture; Figure 7 In (b), align the pressing block 41 at the bottom of the upper cover plate 2 with the pressing block through hole 11 of the contoured base 1, cover the upper cover plate 2, and rotate the pressing block 41 to fix the glass; Figure 7 In (c), the outside-line fixture is erected vertically with the large circle of the hoist slot 21 facing downward, and the large circle of the hoist slot 21 is aligned with the screw 6 of the support plate 81 and placed on it; Figure 7 In (d), press down the off-line clamp to fix. The above process is easy to operate. Off-line clamping can be achieved by twisting the pressure block 41. The installation of the equipment can be completed by aligning the hoist slot 21 and pressing the screw 6, without the need for any tools. Moreover, the clamp is highly versatile and is not only suitable for circular glass, but also for various 2D / 3D structures of glass. It is not only suitable for glass, but also for other material products, such as ceramics, metals, etc.
