Investment casting shell-making manipulator

Abstract

The invention relates to the field of investment casting equipment, and especially relates to an investment casting shell-making manipulator. The investment casting shell-making manipulator comprises a waist rotating and braking device, a front-back swing arm swinging device, a horizontal support horizontal-control device, a bearing seat body overturning device, a hollow gear shaft forward-reverse rotation device, a module clamping-loosening loading and unloading device and a blower gun telescopic device connected to a middle joint of the horizontal support horizontal-control device, wherein the front-back swing arm swing device is arranged at an output end of the waist rotating and braking device, the horizontal support horizontal-control device is arranged at an output end of the front-back swing arm swing device, the bearing seat body overturning device is arranged at an output end of the horizontal support horizontal-control device, and the hollow gear shaft forward-reverse rotation device is arranged at an output end of the bearing seat body overturning device; and the module clamping-loosening loading and unloading device is arranged at an output end of the hollow gear shaft forward-reverse rotation device. According to the invention, in an investment casting shell-making process, most mechanical action requirements of a module can be met, and the investment casting shell-making manipulator is flexible in action, low in manufacturing cost, and easy to maintain.

Description

technical field [0001] The invention relates to investment casting equipment, in particular to a shell-making manipulator for investment casting. Background technique [0002] At present, in the investment casting industry, with the increase in labor costs and the higher requirements for the quality and stability of the shell-making process, shell-making manipulators are gradually being used, and most of the manipulators used are general-purpose six-degree-of-freedom joint robots and column skateboard multi-arm structures. shell-making manipulator. However, the six-degree-of-freedom robot used to make the shell-making manipulator is a large horse-drawn cart, which has poor economic efficiency; although the shell-making manipulator with the column skateboard multi-arm structure has high production capacity, it is large in size and still lacks in functions, such as mechanical The arm only has the function of lifting up and down and turning up and down, without the function of...

However, the six-degree-of-freedom robot used to make the shell-making manipulator is a large horse-drawn cart, which has poor economic efficiency; although the shell-making manipulator with the column skateboard multi-arm structure has high production capacity, it is large in size and still lacks in function. The arm only has the function of lifting up and down and turning up and down, without the function of stretching and retracting, and the clamped module only rotates in one direction, there is no fast forward and reverse movement, and it is impossible to realize actions such as throwing oars. Are these actions correct? The shell-making quality of the mold shell of some shapes of castings is particularly important; and the fixed dobby is limited by the arm distance, and it cannot complete the shell-making process for larger-shaped castings.
