Description

Processing machine chuck with quick release mechanism

technical field

The utility model relates to a chuck used in a grinding/polishing machine, in particular to a processing machine chuck with a quick release mechanism which can quickly complete the disassembly and assembly of the chuck.

Background technique

Grinding or polishing is often used to change the surface roughness of an object and is a technique in modern industrial technology to make the surface of an object smoother. Grinding/polishing surfaces are widely used on metals, glass, ceramics, semiconductors or optical materials.

At present, there is a drag-type grinding/polishing machine, which mainly drives the large turntable 71 and the small turntable 8 (as shown in FIG. 6 , the planetary gear mechanism is not shown in the figure) by a planetary gear mechanism in the machine head. When the large turntable 71 rotates, simultaneously Drive the small turntable 72 located on the large turntable 71, so that the large turntable 71 and the small turntable 72 run like revolution and autorotation. In the polishing barrel 73, the chuck 8 is mainly used for positioning the object and will also rotate with the drive of the planetary gear mechanism, so when the drag-type grinding/polishing machine operates, the object will follow the chuck 8, the small turntable 72, the large The rotation of the turntable 71 forms a revolution, which generates three-dimensional friction relative to the grinding/polishing medium 74 in the grinding/polishing barrel 73, which can achieve the grinding/polishing operation of the surface of the object, and can also control the chuck 8 and small through the planetary gear mechanism. The respective rotational speeds of the turntable 72 and the large turntable 71 generate various running trajectories.

Please refer to FIGS. 7 to 8 , which is a known quick release mechanism for the collet 8, including a fixed part and a movable part, the movable shaft 81 of the movable part can be inserted into the sliding sleeve 82 of the fixed part, and The sliding sleeve 82 can be forced to slide to control the steel ball 84 in the fixed shaft 83 to move and then snap into the ring groove 87 of the movable part, and the fixed shaft 83 is placed on the opposite two sides of the fixed shaft 83 through the gaps 85 on both sides of the end of the sliding sleeve 82. rib 86 on the side. When the movable part is detached from the fixed part, the sliding sleeve 82 is reversely operated, so that the steel ball 84 is separated from the position of the annular groove 87 of the fixed shaft 83, that is, the movable part of the collet can be removed.

However, the aforementioned quick release mechanism of the collet 8 has its defects in use. The surface wear is generated due to the long-term manipulation and rolling of the steel ball 84. Therefore, only the steel ball 84 restricts the movable part relative to the fixed part to prevent the axial separation. In the later use, it is easy for the movable part to fall off relative to the fixed part during the grinding/polishing operation. The falling movable part is in the running state, and it is easy to collide with other chucks 8 and accidentally damage other chucks The object on 8 will not only cause damage to the object and be reimbursed, but in serious cases, it will even damage other chucks 8 and deform and can no longer be used.

In addition, since both the fixed shaft 83 and the movable shaft 81 are designed with oblong rods, the movable part and the fixed part can resist the radial force only by relying on the clamping ribs 86 on both sides of the movable shaft 81 and the gaps 85 on both sides of the fixed shaft 83, so that the movable part and the fixed part can resist the radial force. When the fixed part rotates, the force will be concentrated on the root of the rib 86. In the past, the rib 86 and the movable shaft 81 were fixed by welding, so that the rib 86 was broken from the welding place when the above-mentioned rotational force was applied. The shaft 83 is disengaged.
