Description

Processing machine chuck with quick release mechanism

This creation is about the chuck used by the grinding/polishing machine, especially the disassembly and assembly of the chuck can be completed quickly.

Grinding or polishing is often used to change the surface roughness of objects, and it is a technology that makes the surface of objects smoother in modern industrial technology. Grinding/polishing surface processing is widely used in metal, glass, ceramic, semiconductor 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 with a planetary gear mechanism in the machine head (as shown in the sixth figure, the planetary gear mechanism is not shown in the figure), when the large turntable 71 rotates At the same time, it drives the small turntable 72 on the large turntable 71, so that the large turntable 71 and the small turntable 72 operate like revolutions and rotations. In particular, a plurality of chucks 8 can be movably installed under the small turntable 72 and can be controlled to lower the position and be deeply ground. /In the polishing barrel 73, the chuck 8 is mainly used for positioning objects and will spin with the drive of the planetary gear mechanism, so when the trailing grinding/polishing machine is in operation, the objects will follow the chuck 8, the small turntable 72, The rotation of the large turntable 71 forms a revolution, and the three-dimensional friction is generated from the grinding/polishing medium 74 in the relative grinding/polishing barrel 73, that is, the grinding/polishing operation of the surface of the object can be reached, and the chuck 8 can also be controlled through the planetary gear mechanism. The respective rotation speeds of the small turntable 72 and the large turntable 71 generate various running trajectories.

Please refer to the seventh to eighth figures, which is the aforementioned quick release mechanism of the chuck 8 which includes 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 snap into the ring groove 87 of the movable part, and the two opposite ends 85 of the sliding sleeve 82 are sleeved on the fixed shaft 83 to oppose侧的卡筋86. When the movable part is detached from the fixed part, the sliding sleeve 82 is operated in reverse to disengage the steel ball 84 from the position of the ring groove 87 of the fixed shaft 83, that is, the movable part of the chuck can be removed.

However, the aforementioned quick-release mechanism of the chuck 8 has its shortcomings in use. Due to the long-term control of the steel ball 84, the surface wear is generated, so the steel ball 84 only restricts the movable part relative to the fixed part to prevent axial disengagement. The action force has its shortcomings, and it is easy to fall off the fixed part of the moving part during the grinding/polishing operation in later use. The moving part is in the running state, and it is easy to collide with other chucks 8 and accidentally hurt other chucks. The objects on the 8 not only cause damage to the objects and are reimbursed. In severe cases, they may even damage other chucks 8 and become unusable.

In addition, since the fixed shaft 83 and the movable shaft 81 both adopt an oblong design, only relying on the ribs 86 on both sides of the movable shaft 81 and the notch 85 on both sides of the fixed shaft 83 to achieve the movable part and the fixed part against the radial force, So that when the fixed part rotates, it will concentrate the force on the root of the rib 86. In the past, both the rib 86 and the movable shaft 81 were fixed by welding, so that when the above-mentioned rotating force is applied, the rib 86 breaks from the weld and from The fixed shaft 83 is disengaged.

This creation provides a new type of processing machine chuck with quick release structure, instead of using the quick buckle type of steel balls and grooves to avoid the problem of easy falling off, and can have more to withstand the radial rotation driving force. Force side.

In order to achieve the foregoing objectives and effects, a processing machine chuck with a quick release mechanism is provided, which includes a fixed part and a movable part, wherein: the fixed part has a mounting section, and a mounting groove is provided on the end surface of the mounting section, And the installation groove is provided with a plurality of installation wall surfaces; the movable part has a penetration section, and the penetration section of the movable section can be movably inserted into the installation groove, and the circumferential side of the penetration section is provided with The plurality of penetration walls of the plurality of mounting walls interlock with each other, and each of the plurality of penetration surfaces is provided with a perforation; and a locking group including a locking seat and a locking rod, the locking seat is disposed on the peripheral side of the installation section , And the locking rod is inserted into the locking base, and one end of the locking rod is inserted into the installation slot into the installation slot and into the perforation, so that the movable part and the fixed part form a locking body After the locking lever is moved and detached from the perforation, the penetrating section of the movable part can be detached from the mounting groove of the fixed part, so that the movable part and the fixed part form a separated state.

Please refer to the first to fifth figures, the figure discloses a processing machine chuck with a quick release mechanism, which includes a fixed part 1 and a movable part 2, wherein:

The fixing portion 1 has a mounting section 11, and an end groove of the mounting section 11 is provided with a mounting groove 12, and the mounting groove 12 is provided with a plurality of mounting wall surfaces 121; in this mounting groove 12, four mounting wall surfaces 121 are used as For example, a through hole 13 communicating with the mounting groove 12 is provided on the peripheral side of the mounting section 11, and furthermore, the opposite end of the mounting section 11 of the fixed portion 1 is connected to a small turntable (not shown in the figure) of the trailing grinding/polishing machine ) Group connection.
