Description

An indexing device for a vertical turntable

technical field

The utility model relates to the technical field of machining, in particular to an indexing device for a vertical turntable.

Background technique

Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing method, it can be divided into cutting processing and pressure processing. The process can be divided into casting, forging, stamping, welding, machining, assembly and other processes. The mechanical manufacturing process generally refers to the sum of the machining process of parts and the assembly process of machines. Other processes are called auxiliary processes. Processes, such as transportation, storage, power supply, equipment maintenance, etc. The technological process is composed of one or several sequentially arranged processes, and a process is composed of several working steps. Especially in the process of cutting, such as milling machine and grinding machine, it is often necessary to use a turntable, which can turn the workpiece through a certain angle intermittently, so as to facilitate the processing of the workpiece. Commonly used turntables are divided into horizontal turntables and vertical turntables. Vertical turntables are widely used in equipment because of their good structure and economy. The indexing device of the common vertical turntable is a worm indexing mechanism. The worm indexing mechanism is mainly composed of a worm, a worm wheel and an auxiliary support component. When the worm rotates a certain number of revolutions, the corresponding worm wheel rotates through a certain angle to achieve the indexing requirements. However, the indexing accuracy of this indexing device is relatively poor, which is unfavorable for the processing operation of workpieces.

Further, a rolling bearing is provided between the turntable and the supporting shaft.

Further, the trigger switch is a roller trigger switch.

Further, the position of the limit screw is adjustable.

Compared with the prior art, the utility model has the following advantages and effects: the third piston rod of the third cylinder is retracted, the second block and the roller are disengaged, and the first cylinder drives the slide plate to move right along the guide rail. The second piston rod is in the extended state, that is, the first block blocks a roller, so the turntable rotates counterclockwise with the right movement of the skateboard. After the turntable turns 30 degrees, the roller touches the trigger switch, and the trigger switch sends out a signal , the third cylinder drives the second block to swing counterclockwise to lock the other roller, thereby locking the turntable, the second piston rod of the second cylinder retracts, the first cylinder pushes the slide plate to move to the left, and the second cylinder of the second cylinder The piston rod stretches out, and the first block blocks a roller again. So far, an indexing action process ends. A rolling bearing is arranged between the turntable and the supporting shaft, which reduces wear between the turntable and the supporting shaft, facilitates the smooth rotation of the turntable, and prolongs the service life of the turntable and the supporting shaft. The trigger switch is a roller trigger switch with simple structure, sensitive response and long service life. The position of the limit screw is adjustable, which is beneficial to realize the position limitation of the slide plate and avoid accidents. The utility model has good indexing accuracy, is beneficial to the processing operation of workpieces, has reasonable structure and good stability.
