Embodiment

[0022] Embodiment: a turntable mechanism, comprising a rotating disk 1, an upper bracket 2 positioned above the rotating disk, a lower bracket 3 positioned below the rotating disk, a rotating lever 4, an eccentric wheel 5 fixed to the upper end of the rotating lever and A driving device 6 connected to the lower end of the rotating lever and driving the rotating lever to rotate around its own axis, a circle of grooves 11 is provided in the middle of the rotating disc, and the circle of grooves 11 is formed by a plurality of arc-shaped grooves. The monomers 111 are arranged and connected along the circumferential direction. The eccentric wheel 5 is located in the groove 11 and cooperates with the arc groove monomer 111. The edge of the rotating disk 1 is provided with a circle of processing The said circle of processing positions is composed of several processing positions 12 arranged at intervals along the circumferential direction, and the number of said processing positions 12...

Abstract

The invention discloses a turntable mechanism, which comprises a rotating disc, an upper bracket, a lower bracket, a rotating driving lever, an eccentric wheel, a driving device, a pneumatic suspension structure and a brake device. Indexing rotation of the rotating disc is realized in a way that the eccentric wheel is matched with a groove, and the eccentric wheel drives the rotating disc to rotate and the precise localization of the eccentric wheel is realized; in the pneumatic suspension way, the friction loss of the rotating disc is reduced when the rotating disc rotates; a copper disc is pushed by air pressure, the copper disc is pushed to contact the rotating disc to drive the rotating disc to brake, so that the problem of unstable braking of the rotating disc caused by that an element surface is worn due to radial braking is solved; during transposition, the precise localization of the rotating disc is realized by locating pins; and variable speed rotation of the eccentric wheel is realized through a structural design of the driving device, and continuous transition is realized by matching with a processing time and a transposition time of the rotating disc.

Description

technical field [0001] The invention belongs to a turntable device in the industrial technology, and in particular relates to a turntable workbench structure. Background technique [0002] As the writing requirements of ballpoint pens become higher and higher, the structure of the pen head becomes more and more complicated. In order to improve production efficiency and parts processing quality, various multi-station automatic machine tools have been invented in recent years, which greatly reduces the original processing error and improves the processing accuracy. Although my country's linear chain type multi-station pen-making processing machine tool meets the requirements of my country's pen-making to a certain extent, due to the limitations of the chain itself, the processing quality is unstable when processing the pen tip, the accuracy of the pen tip is not high, and the machine tool Equipment is prone to failure. With the development of existing technology, people often...
