Description

Technical Field

[0001] This utility model relates to a fixing fixture, and more particularly to a fixing fixture for glass production and processing. Background Technology

[0002] In the glass manufacturing process, grinding is mostly used. This requires clamping the glass to be processed using fixtures to facilitate subsequent processing. However, traditional fixtures often use simple clamping mechanisms to hold the workpiece in place, using positive pressure and friction to prevent displacement during processing. However, the rigid contact between the workpiece and the fixture is not suitable for fragile items like glass, as it can easily cause cracks on the glass surface and damage the glass. In addition, traditional fixtures lack flexibility and adaptability, making it difficult to meet the processing needs of glass of different sizes.

[0003] Therefore, a new type of fixed tooling is needed for glass production and processing. Utility Model Content

[0004] In order to overcome the shortcomings of traditional fixed fixtures in that the clamping force is difficult to control, the technical problem of this utility model is to provide a fixed fixture for glass production and processing.

[0005] A fixed fixture for glass production and processing includes support columns, a first base plate, a second base plate, an annular frame, an annular component, a suction cup, a circular barrel, a vacuum pump, and an anti-slip plate. The first base plate and the second base plate are symmetrically distributed vertically. Support columns are fixedly connected between the four corners of the first base plate and the second base plate. An annular frame and an annular component are fixedly installed in the middle of the upper side of the first base plate. The annular component is located inside the annular frame and the two are connected. A suction cup is fixedly connected to the upper end of the annular component. The circular barrel passes through the annular component and is fixedly installed in the middle of the first base plate on the second base plate. The contact part between the annular component and the circular barrel is sealed. A vacuum pump is fixedly installed at the bottom of the circular barrel. The exhaust pipe of the vacuum pump passes through the outside of the circular barrel. An anti-slip plate is fixedly connected to the upper end of the circular barrel.

[0006] Furthermore, the upper part of the circular barrel has several air extraction holes.

[0007] Furthermore, the ring-shaped component is made of rigid plastic.

[0008] Furthermore, it also includes slide rails, guide rods, L-shaped parts, springs, arc-shaped clamps, tightening screws, and guide rods. Slide rails are fixedly installed on all four sides of the second base plate, and guide rods are fixedly connected to the middle of each slide rail. L-shaped parts are slidably installed on the side of the slide rail away from the circular barrel, and guide rods are inserted inside the L-shaped parts. Springs are fixedly connected between the shorter right-angled side of the L-shaped part and the end of the slide rail near the circular barrel, and the guide rods are located inside the springs. Arc-shaped clamps are fixedly installed on the upper end of the longer right-angled side of the L-shaped parts, and tightening screws are threadedly installed in the middle of the upper end of the arc-shaped clamps. Guide rods are fixedly connected to both sides of the upper end of the arc-shaped clamps.

[0009] Furthermore, the L-shaped component slides along the guide surface of the slide rail, and in the part that contacts the slide rail, its length only covers half of the slide rail.

[0010] Furthermore, the curved clamp, the ring-shaped component, and the upper surface of the anti-slip plate are on the same horizontal plane.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model uses an annular part to contact the glass and utilizes the vacuum pump at the bottom of the circular barrel and the air extraction hole at the top to generate negative pressure, thereby adsorbing and fixing the glass. This method achieves better control of the fixing force on the glass and avoids damage to the glass.

[0012] 2. This utility model uses a spring connecting the slide rail and the L-shaped part to allow the arc-shaped clamping plate to adjust its position according to the different side lengths of the glass, thus enabling the fixed fixture to effectively clamp and fix glass of different sizes, improving the versatility and practicality of the fixture.

Detailed Implementation

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: A fixed fixture for glass production and processing, such as... Figures 1-4 As shown, the device includes a support column 1, a first base plate 2, a second base plate 3, an annular frame 4, an annular component 5, a suction cup 6, a circular barrel 7, a vacuum pump 701, and an anti-slip plate 8. The first base plate 2 and the second base plate 3 are symmetrically distributed vertically. Support columns 1 are fixed between the four corners of the first base plate 2 and the second base plate 3. The annular frame 4 and the annular component 5 are fixedly installed on the upper middle part of the first base plate 2 by screws. The annular component 5 is located inside the annular frame 4 and the two are connected. The suction cup 6 is fixedly connected to the upper end of the annular component 5. The circular barrel 7 passes through the annular component 5 and is fixedly installed on the second base plate 3 with screws in the middle part of the first base plate 2. The contact part between the annular component 5 and the circular barrel 7 is sealed. The vacuum pump 701 is fixedly installed on the bottom of the circular barrel 7 with screws. The exhaust pipe of the vacuum pump 701 passes through the outside of the circular barrel 7. The anti-slip plate 8 is fixedly connected to the upper end of the circular barrel 7. Several suction holes are opened in the upper half of the circular barrel 7. The annular component 5 is made of rigid plastic.

[0021] like Figure 5 As shown, it also includes a slide rail 9, a guide rod 901, an L-shaped component 10, a spring 101, an arc-shaped clamping plate 11, a tightening screw 12, and a guide rod 13. Slide rails 9 are fixedly installed around the second base plate 3 by screws. A guide rod 901 is fixedly connected to the middle of each slide rail 9. An L-shaped component 10 is slidably installed on the side of the slide rail 9 away from the circular barrel 7. The guide rod 901 passes through the L-shaped component 10. A spring 10 is fixedly connected between the shorter right-angled side of the L-shaped component 10 and the end of the slide rail 9 closest to the circular barrel 7. 1. The guide rod 901 is located inside the spring 101. The upper end of the longer right-angled side of the L-shaped part 10 is fixed with an arc-shaped clamp 11 by screws. The upper middle part of the arc-shaped clamp 11 is threaded with a tightening screw 12. The upper two sides of the arc-shaped clamp 11 are fixed with guide rods 13. The L-shaped part 10 slides along the guide surface of the slide rail 9. In the part that contacts the slide rail 9, its length only covers half of the slide rail 9. The arc-shaped clamp 11, the ring part 5 and the upper end surface of the anti-slip plate 8 are on the same horizontal plane.

[0022] This fixture is used when fixing glass during production and processing. First, the surface with the largest area of ​​the glass to be fixed is aligned parallel to the horizontal plane. Then, the entire glass piece is placed on the anti-slip plate 8. During this process, the glass first completely covers the annular component 5, then contacts the suction cup 6 at the top of the annular component 5, causing the suction cup 6 to expand along both sides, compressing the air inside the suction cup 6 to create a negative pressure, thus generating an initial suction force on the glass. After the glass is properly positioned on the annular component 5, the vacuum pump 701 at the bottom of the circular barrel 7 is activated. The vacuum pump 701 extracts the air between the annular component 5 and the glass through the air extraction hole on the circular barrel 7, creating a negative pressure between the annular component 5 and the inside of the glass, thereby adsorbing and fixing the glass. Then... The glass is moved slowly so that its edge enters the clamping area of ​​the curved clamp 11. During this process, the longer sides of the glass exert opposite thrusts on the curved clamp 11 and the L-shaped piece 10 when they enter the clamping area of ​​the curved clamp 11. At this time, the springs 101 connected to the bottom of the L-shaped pieces 10 on both sides are stretched and move in opposite directions along the slide rail 9 until the glass edge is in close contact with the curved clamp 11. When all four sides of the glass are in the curved clamp 11, the screw 12 is rotated and tightened. Under the guidance of the guide rod 13, the screw 12 drives the curved clamp 11 to clamp downward to fix the glass. Then the glass is processed. During the processing, the ring frame 4 supports and fixes the ring piece 5 to prevent the ring piece 5 from shifting.

[0023] After processing is completed, by rotating the tightening screw 12, the tightening screw 12 drives the arc-shaped clamp 11 to move upward under the guidance of the guide rod 13 and no longer contact the glass. Then, the vacuum pump 701 is turned off, and the glass is slowly removed from the annular part 5. At this time, the spring 101 connected to the L-shaped part 10 drives the L-shaped part 10 to reset along the slide rail 9.

The scope of the following claims should be given the broadest interpretation in order to cover all variations and equivalent structures and functions.
