Description

Technical Field

[0001] The utility model relates to the technical field of zirconia processing equipment, and particularly relates to a pneumatic clamping mechanism of a zirconia block cutting device. Background Art

[0002] Zirconia can be used to make porcelain teeth or all-ceramic teeth, and can also be made into zirconia beads. As a polishing raw material, zirconia beads can polish gold, silver or other metal objects. Zirconia can also be used to make artificial gems after mixing with other materials, and its specific application scenarios are relatively wide.

[0003] At present, in the process of manufacturing porcelain teeth or all-ceramic teeth, first, zirconia needs to be pressed into a disc-shaped zirconia block, and then the zirconia block is placed into a cutting device to cut out a specific shape. After taking it out, other processes such as sintering and forming are carried out to complete the production of porcelain teeth or all-ceramic teeth. Before cutting the disc-shaped zirconia block, a special fixture is required to fix it. Currently, it is usually manual to place the zirconia block into the fixture and use a screwdriver to install and tighten the fixing screws, so that the zirconia block is clamped and fixed. After the cutting action is completed, the fixture is loosened manually with a screwdriver, and the semi-finished product to be sintered is taken out. Therefore, the whole cutting action requires manual waiting beside. At the same time, due to a large amount of flying droplets during the cutting process of the zirconia block, the current cutting device usually places the cutting mechanism in a box, resulting in more inconvenient installation and disassembly of the zirconia block.

[0004] Under the above background, the inventor designed a pneumatic clamping mechanism of a zirconia block cutting device to solve one or more of the above problems, and thus this application is proposed. Content of the Utility Model

[0032] The following will detail the present utility model by referring to the drawings and in conjunction with embodiments.

[0033] As Figure 1 and Figure 3As shown in the figure, this embodiment provides a pneumatic clamping mechanism for a zirconia block cutting device, which includes a fixture body 1 having a clamping groove 12 and a number of clamping parts 11 located on the fixture body 1;

[0034] It further includes a clamping assembly 2 provided on the clamping part 11 and driven by air pressure. The power output end of the clamping assembly 2 is located at the top or / and bottom of the clamping groove 12.

[0035] The design concept of this embodiment is to set a fixture body 1 with an arc-shaped clamping groove 12, and set a clamping part 11 and a clamping assembly 2 on the fixture body 1. The clamping assembly 2 is driven by air pressure. After the disc-shaped material 3 is placed in the arc-shaped clamping groove 12, the clamping assembly 2 is driven by air pressure, so that its power output end can press against the top or / and bottom of the disc-shaped material 3, thereby pressing the disc-shaped material 3 tightly. Compared with the method of using screws for fastening in the prior art, the fastening operation of the disc-shaped material 3 is convenient, the fixing efficiency is high, and the fastening force is more stable, avoiding the problems of unstable clamping or excessive clamping force, resulting in damage to the disc-shaped material 3.

[0036] Specifically, in this embodiment, as Figure 1 and Figure 2 shown, it further includes a main air duct 15 and a branch air duct 151 provided in the fixture body 1, and an air inlet pipe 13 and an air outlet pipe 14 respectively communicating with both ends of the main air duct 15;

[0037] The power input ends of the clamping assemblies 2 are all communicated with the main air duct 15 through the branch air ducts 151. By setting the main air duct 15 and the branch air ducts 151, all the clamping assemblies 2 can be driven by the same air source, which can streamline the structure and improve the synchronism of the clamping actions of the clamping assemblies 2 at the same time.

[0038] Specifically, in this embodiment, as Figure 1 and Figure 2 shown, the axis shape of the main air duct 15 is arc-shaped. In this embodiment, the shape of the fixture body 1 is arc-shaped, and the center of the arc corresponding to the fixture body 1 coincides with the center of the arc corresponding to the axis shape of the main air duct 15. In this embodiment, the cross-section of the main air duct 15 is circular.

[0039] Specifically, in this embodiment, as Figure 1 and Figure 2 shown, the clamping part 11 includes a piston cavity 111, and the branch air ducts 151 are all communicated with the piston cavity 111;

[0040] The clamping assembly 2 includes a piston body 21. The piston body 21 is arranged in the piston cavity 111 and is slidably connected thereto in a direction perpendicular to the clamping groove 12;

[0041] The clamping assembly 2 further includes a piston rod 23 and an elastic pressing plate 24. The elastic pressing plate 24 and the piston body 21 are respectively fixed at both ends of the piston rod 23. When the air inlet pipe 13 is in the air inlet state, the rising air pressure will push the piston body 21, and then push the elastic pressing plate 24 through the piston rod 23 to move towards the middle area of the clamping groove 12, thereby clamping the disc-shaped material 3.

[0042] Specifically, in this embodiment, as Figure 2 shown, the clamping assembly 2 further includes a return spring 22 disposed in the piston cavity 111 and sleeved on the piston rod 23. By providing the return spring 22, the clamping assembly 2 can be quickly reset to prepare for the next clamping action.

[0043] Specifically, in this embodiment, as Figure 1 and Figure 2 shown, the piston cavity 111 is an open cavity with an opening at the top, and the inner peripheral wall of the upper region of the piston cavity 111 is provided with internal threads;

[0044] The clamping portion 11 further includes a sealing cover 112 threadedly connected to the piston cavity 111. The piston cavity 111 forms a sealed cavity through the sealing cover 112. The piston cavity 111 in this embodiment is an open cavity, and its top is threadedly connected with a sealing cover 112, which can facilitate the installation of the clamping assembly 2 and the subsequent maintenance disassembly.

[0045] Specifically, in this embodiment, as Figure 1 and Figure 2 shown, a sealing ring installation groove is provided at the top of the clamping portion 11;

[0046] An elastic sealing ring 113 is further provided between the sealing cover 112 and the clamping portion 11. By providing the elastic sealing ring 113, the sealing performance of the piston cavity 111 when the sealing cover 112 is installed can be further improved, and problems such as air leakage can be avoided.

[0047] Specifically, in this embodiment, as Figures 1 to 3 shown, a plurality of the clamping portions 11 and the clamping assemblies 2 are evenly distributed on the clamping groove 12. The uniform distribution of the clamping portions 11 and the clamping assemblies 2 can improve the stability of the disc-shaped material 3 after being clamped.

[0048] Specifically, in this embodiment, as Figure 2 shown, the power output ends of the clamping assemblies 2 are all located at the top of the clamping groove 12. In some embodiments, the power output ends of the clamping assemblies 2 can also be provided at the bottom of the clamping groove 12, or at both the top and bottom of the clamping groove 12 at the same time.

[0049] Specifically, in this embodiment, as Figure 2As shown, an elastic gasket 121 is further provided at the bottom of the clamping groove 12. The elastic gasket 121 can play a certain buffering role during the clamping action of the clamping assembly 2.
