Telescopic arm device

Abstract

The invention provides a telescopic arm device which comprises a fixed part, wherein a first direct moving part is slidably connected with the fixed part; a second direct moving part is slidably connected with the first direct moving part; a first driving part and a second driving part are connected with the fixed part; the first driving part is connected with a first toothed belt fixedly arranged at the first direct moving part and is capable of driving the first direct moving part to slide by virtue of the first toothed belt; the second driving part is connected with a driving belt toothed belt movably arranged at the first direct driving part; the driving belt toothed belt is meshed with a second toothed belt fixedly arranged at the second direct moving part and is capable of driving the second direct moving part to slide. According to the telescopic arm device provided by the invention, a multilevel telescopic structure is achieved by virtue of the first direct moving part and the second direct moving part in combination with the first and second driving parts which are fixedly arranged, so that a relatively long telescopic distance can be achieved with a relatively short length; By virtue of adopting a toothed belt driving mode, the structure is simplified and production and processing are convenient.

Description

technical field [0001] The invention relates to a driving device of a manipulator, in particular to a telescopic arm device. Background technique [0002] The molded product take-out operation device is a device that takes out molded products from a molding machine, such as an injection molding machine. After the molding process of the molding machine is completed, the mold is opened. During this period, the molded product take-out operation device enters the inside of the molding machine from the upper part of the molding machine and takes out the mold. products, and then leave to work outside the molding machine. During this period, the molding machine is in a standby state waiting for the next molding process. In order to shorten the standby time of the molding machine, the molded product take-out operation device that takes out the molded product is usually installed on the upper part of the molding machine. [0003] In order to take the molded product out of the moldi...

AI Technical Summary

Problems solved by technology

[0004] In this way, if the overall height of the molding machine that needs to be installed with the molded product extraction device is too high, or if the distance from the upper end of the molding machine to the upper roof is very low, it will be difficult or even impossible to install the molded product removal device, and the lifting and moving distance will be large. If so, the lifting and moving time will be longer
