Description

Processing machine chuck with quick-release mechanism

Technical Field

The utility model relates to a chuck that grinding/burnishing machine used, especially can accomplish the quick detach mechanism's of utensil quick detach machine chuck of chuck dismouting fast.

Background

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

At present, there is a drag-type grinding/polishing machine, which mainly uses a planetary gear mechanism to drive a large turntable 71 and a small turntable 8 (as shown in fig. 6, a planetary gear mechanism is not shown), and drives a small turntable 72 located on the large turntable 71 when the large turntable 71 rotates, so that the large turntable 71 and the small turntable 72 have the revolution and rotation operations, especially a plurality of chucks 8 can be movably installed below the small turntable 72 and can be controlled to descend to enter a grinding/polishing barrel 73, the chucks 8 are mainly used to position an object and can also spin under the driving of the planetary gear mechanism, so when the drag-type grinding/polishing machine operates, the object will form the revolution under the rotation of the chucks 8, the small turntable 72 and the large turntable 71, and generate the three-dimensional friction from the grinding/polishing medium 74 in the opposite grinding/polishing barrel 73, that is able to achieve the grinding/polishing operation of the object surface, the planetary gear mechanism can also be used for controlling the respective rotating speeds of the chuck 8, the small turntable 72 and the large turntable 71 to generate various running tracks.

Please refer to fig. 7 to 8, which show the above-mentioned quick release mechanism of the prior art chuck 8, which includes a fixed portion and a movable portion, wherein the movable shaft 81 of the movable portion can be inserted into the sliding sleeve 82 of the fixed portion, and the sliding sleeve 82 can be forced to slide to control the steel balls 84 in the fixed shaft 83 to move and then be locked in the annular groove 87 of the movable portion, and the two side notches 85 at the end of the sliding sleeve 82 are used to sleeve the locking ribs 86 at the two opposite sides of the fixed shaft 83. When the movable part is detached from the fixed part, the sliding sleeve 82 is operated reversely to disengage the steel balls 84 from the annular groove 87 of the fixed shaft 83, so that the movable part of the chuck can be detached.

However, the above quick release mechanism for the chuck 8 has a disadvantage in use that the steel balls 84 are operated and rolled for a long time to generate surface abrasion, so that the steel balls 84 only limit the acting force of the movable part relative to the fixed part to prevent axial separation, and the movable part is easy to fall off relative to the fixed part during the grinding/polishing operation in the later period of use, and the fallen movable part is in a running state, and is easy to collide with other chucks 8 to accidentally injure objects on other chucks 8, thereby not only causing damage to the objects and reporting pins, but also even damaging other chucks 8 to deform and being incapable of being reused under severe conditions.

In addition, since the fixed shaft 83 and the movable shaft 81 are both designed as long round rods, the radial acting force of the movable part and the fixed part can be resisted only by the clamping ribs 86 on both sides of the movable shaft 81 and the notches 85 on both sides of the fixed shaft 83, so that the root of the clamping rib 86 can be intensively stressed when the fixed part rotates, and the clamping rib 86 and the movable shaft 81 are fixed by welding in the prior art, so that the clamping rib 86 is broken from the welding part and is separated from the fixed shaft 83 when the rotating acting force is borne.
