A mechanical arm with adjustable angle

Abstract

The invention discloses an angle-adjustable mechanical arm, which comprises a support column. A mounting groove is opened on the top of the support column. An upper rotating shaft is rotatably connected between the tops of both sides of the inner wall of the mounting groove, and the two sides of the inner wall of the mounting groove are There is a lower rotating shaft rotating between the bottoms, a semicircular gear is fixedly installed on the upper rotating shaft, a rotating rod is fixedly connected to the plane side of the semicircular gear, a main gear is fixedly installed on the lower rotating shaft, the main gear and the semicircular gear The outer wall of the support column is rotatably connected with the main support rod, and the end of the main support rod away from the support column is provided with a groove, and the auxiliary support rod is slidably installed in the groove. In the present invention, through the design of the installation groove, the upper shaft, the lower shaft, the semicircular gear and the main gear, the angle between the support column and the rotation rod can be adjusted at 180 degrees, and the main support rod and the auxiliary support rod And the design of the spring can play an auxiliary supporting role for the supporting column and the rotating rod.

Description

technical field [0001] The invention relates to the technical field of automatic mechanical equipment, in particular to an angle-adjustable mechanical arm. Background technique [0002] Manipulators are the product of social development and technological progress. On the one hand, manipulators can replace part or even all of human operations, liberating the labor force and facilitating the industrialization of production; on the other hand, manipulators can overcome harsh tasks such as high temperature, high pressure, pollution, and radioactivity It is more widely used in the production of some dangerous industries. Therefore, the manipulator is suitable for the trend of modern production and has strong vitality. [0003] However, the structure of the mechanical arm of the existing manipulator is relatively complicated, the price is expensive, the control program is complicated, and the angle adjustment range between the mechanical arm and the mechanical arm is small, the wo...

Problems solved by technology

[0003] But the structure of the mechanical arm of the existing manipulator is relatively complicated, the price is expensive, the control program is complicated, and the angle adjustment range between the mechanical arm and the mechanical arm is small, the working range is very limited, and the length of the clamping hand of the existing mechanical arm cannot be adjusted. , When encountering large or small goods, it is often necessary to replace the gripper, which is time-consuming and laborious. For this reason, we have designed an angle-adjustable mechanical arm to solve the above problems
