Abstract

The invention discloses a limiting device, which comprises a fixing base, a poking block, a locking rod, a tension spring, a linear bearing piece and a plurality of guide wheels. Grooves are formed on side surfaces of the guide wheels and are symmetrically pivoted in the fixing base in two rows so as to form guide slots; the poking block has a collimating part, wherein one side of the collimatingpart is provided with a convexly extending blocking part; the collimating part is embedded inside the guide slots in a sliding mode; the blocking part is positioned between two adjacent guide wheels in the guide wheels in the same row and convexly extends out of the guide slots; and a chute is formed on the collimating part in an inclined mode. On end of the locking rod is movably connected in the chute, and the other end of the locking rod movably passes through the linear bearing piece; the linear bearing piece is fixedly connected with the fixing base; the tension spring is in a stretchingshape; and one end of the tension spring is fixed with the fixing base, and the other end of the tension spring is fixed with the poking block. The limiting device has simple and compact structure and low cost, is convenient to maintain and can be widely applied.

Description

technical field [0001] The invention relates to a limiting device, in particular to a limiting device for limiting or adjusting the position of parts. Background technique [0002] With the development of industrial technology and the continuous improvement of the level of industrial automation, the requirements for industrial equipment, processing technology and product quality are also continuously improved. In many fields such as semiconductor automated production, printing, food processing, etc. The position fixing, adjustment and limit etc. all need to use the limit device to complete. Whether the position adjustment is accurate directly affects whether the production equipment can operate normally and the production efficiency of the product. [0003] In the field of semiconductor production, especially in the production process of digital products such as OLED (Organic Light-Emitting Diode) display screens, the limit device plays a vital role in the processing process...
