Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass processing technology, and in particular to a glass edge grinding and chamfering device. Background Technology
[0002] Glass, as a transparent, hard, and relatively brittle amorphous material, is widely used in modern architecture, furniture, electronics, and automobiles. Its edges are usually sharp and can easily cause scratches to the human body, as well as pose a risk of breakage due to impacts. Therefore, before use, the edges of glass need to be ground and chamfered to improve safety and aesthetics, while reducing the probability of breakage caused by stress concentration.
[0003] Most common glass edging and chamfering equipment currently uses a single-station structure, which means that a set of grinding heads sequentially chamfers and grinds the four corners of the glass. This type of device usually relies on manual or semi-automatic methods to move the glass or grinding head position. After completing the chamfering of one corner, the position is adjusted to process the next corner.
[0004] Because the four chamfers are processed independently without a synchronous control mechanism, the grinding depth, angle and surface finish of each corner are easily inconsistent, resulting in uneven chamfers among the four sets. This is especially true when performing high-precision chamfering on square glass, where it is difficult to ensure the uniformity of the chamfer dimensions, affecting the overall aesthetics and assembly accuracy of the product. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figure 1-4 As shown, this utility model has the following three specific embodiments.
[0026] Example 1
[0027] A glass edging and beveling device includes a base 1, with a first mounting cavity 13 and a second mounting cavity 14 inside the base 1. The first mounting cavity 13 is located directly below the second mounting cavity 14. A second motor 6 is fixedly connected inside the first mounting cavity 13. The output shaft of the second motor 6 extends through to the outside of the base 1 and is fixedly connected to a mounting base 2. The device also includes:
[0028] Clamping mechanism 3 is installed on the side wall of mounting base 2 and is used to clamp and fix the glass.
[0029] The chamfering mechanism 5 is installed on the side wall of the base 1 and is used to simultaneously chamfer and grind the four corners of the glass.
[0030] Adjustment mechanism 4, there is a pair of adjustment mechanisms 4, which are located in the second mounting cavity 14 and the mounting base 2 respectively, and are used to adjust the position of clamping mechanism 3 and chamfering mechanism 5 respectively.
[0031] Preferably, the upper end face of the base 1 is provided with a first annular groove 11, and the lower end face of the mounting base 2 is provided with a second annular groove 21 corresponding to the first annular groove 11. A plurality of balls 12 are provided between the first annular groove 11 and the second annular groove 21. The plurality of balls 12 are evenly distributed along the annular direction to support the mounting base 2 and assist its rotation.
[0032] In this embodiment, as Figures 1-2 As shown, the glass is first placed flat on the top surface of the mounting base 2. The clamping mechanism 3 is retracted by the adjustment mechanism 4 in the mounting base 2, and the glass is gently and firmly centered and clamped. Then, the adjustment mechanism 4 in the second mounting cavity 14 is driven to retract the chamfering mechanism 5. The chamfering mechanism 5 is started. Then, the second motor 6 is turned on, and the mounting base 2 rotates at a constant speed on the annular raceway of the ball bearing 12. The four corners of the glass pass through the chamfering mechanism 5 at the same time. The chamfering of the whole circle can be completed in one rotation. The process is smooth and without impact.
[0033] Example 2
[0034] The difference from Embodiment 1 is that this embodiment discloses a clamping mechanism 3 and a chamfering mechanism 5;
[0035] The clamping mechanism 3 includes a telescopic rod 31, which is provided in four sets. The telescopic rod 31 is slidably connected inside the mounting base 2. One end of the telescopic rod 31 away from the axis of the mounting base 2 extends through to the outside of the mounting base 2 and is fixedly connected to the clamping base 32. The bottom of the mounting base 2 is provided with four sets of first sliding grooves 22. Each set of first sliding grooves 22 is slidably connected to a first slider 36. The upper end of the first slider 36 is fixedly connected to the lower end of the telescopic rod 31.
[0036] The clamping seat 32 has a sliding rod 33 inside, and a clamping plate 34 is fixedly connected to one end of the sliding rod 33 facing the axis of the mounting seat 2. The clamping plate 34 and the clamping seat 32 are fixedly connected by a spring 35.
[0037] The chamfering mechanism 5 includes four mounting rods 51. The mounting rods 51 are slidably connected inside the second mounting cavity 14. One end of the mounting rod 51 away from the axis of the base 1 extends through to the outside of the base 1. A second motor 6 is fixedly connected to the end of the mounting rod 51. A grinding blade 54 is fixedly connected to the output shaft end of the second motor 6. Four sets of second sliding grooves 141 are opened at the bottom of the second mounting cavity 14. A second slider 53 is slidably connected inside each set of second sliding grooves 141. The upper end of the second slider 53 is fixedly connected to the lower end of the mounting rod 51.
[0038] In this embodiment, as Figures 2-4 As shown, the upper adjustment mechanism 4 drives the telescopic rod 31 to extend radially along the mounting base 2, and the outer end is folded to form a clamping seat 32. The clamping seat 32 has a pre-reserved guide hole, through which the slide rod 33 passes. The clamping plate 34 always fits against the edge of the glass under the push of the spring 35, which maintains the self-centering effect and avoids over-pressure breakage. The lower adjustment mechanism 4 drives the mounting rod 51 to move radially along the base 1, which drives the end folded corner mounting first motor 52 to move, so that the grinding blade 54 in the first motor 52 moves to the designated position. Then the first motor 52 is started to drive the grinding blade 54 to rotate at high speed. The second motor 6 drives the mounting base 2 to rotate, so that the four corners of the glass pass through the grinding blade 54 synchronously. The chamfering of the whole circle can be completed in one rotation. The process is smooth and without impact.
[0039] Example 3
[0040] The difference from Embodiment 2 is that this embodiment discloses an adjustment mechanism 4;
[0041] The adjustment mechanism 4 includes a fixed ring 41 fixed inside the second mounting cavity 14 and the mounting base 2. A sleeve 42 is rotatably connected inside the fixed ring 41. A rotating disk 43 and a worm gear 44 are fixedly connected to the outer wall of the sleeve 42. The worm gear 44 is located above the rotating disk 43. Four sets of arc-shaped grooves 45 are equidistantly opened on the upper surface of the rotating disk 43. Limit blocks 47 are slidably connected inside each arc-shaped groove 45. The lower ends of the limit blocks 47 are fixedly connected to the upper ends of the corresponding mounting rods 51 and telescopic rods 31, respectively. A worm 46 is meshed on the side wall of the worm gear 44. The worm 46 is rotatably connected to the corresponding base 1 and mounting base 2, respectively. The inner wall of the sleeve 42 is rotatably connected to the motor output shaft end.
[0042] In this embodiment, as Figure 3As shown, rotating the worm gear 46 drives the worm wheel 44 to rotate, which in turn drives the sleeve 42 to rotate, which in turn drives the rotating disk 43 to rotate, which in turn drives the arc groove 45 to move, and the movement of the arc groove 45 drives the limiting block 47 to move radially in a square shape along the sleeve 42, thereby providing power for adjusting the position of the telescopic rod 31 or the mounting rod 51.
[0043] The working principle of this utility model is as follows:
[0044] Place the square glass flat on the top surface of the mounting base 2. Rotate the upper worm gear 46, and the worm wheel 44 will drive the sleeve 42 and the rotating disk 43 to rotate synchronously. The arc groove 45 will push the limiting block 47 to slide inward, and the four sets of telescopic rods 31 will retract simultaneously. The clamping plate 34 will gently press the glass under the buffer of the spring 35, completing the self-centering clamping. Rotate the lower worm gear 46, and the lower rotating disk 43 will rotate in the same way. The four mounting rods 51 will extend or retract synchronously, driving the grinding blades 54 to approach the four corners of the glass. The worm gear 46 will stop rotating and lock itself, keeping the blade position unchanged. Start the first motor 52, and the grinding blades 54 will rotate at high speed. Then start the second motor 6, and the mounting base 2 will rotate at a constant speed on the annular raceway of the ball bearings 12. The four corners of the glass will pass through the four grinding blades 54 at the same time. Four chamfers can be completed in one rotation. When the rotation stops, the processing is over. Rotate the upper worm gear 46 in the opposite direction to release the clamp and pick up the part.
[0045] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
