High-speed and heavy-duty truss mechanical arm

Abstract

The invention discloses a high-speed and heavy-duty truss mechanical arm. The high-speed and heavy-duty truss mechanical arm comprises two supporting legs which are arranged symmetrically, a transverse beam (1) is supported between the two supporting legs, a guide rail (2) is fixedly connected to the transverse beam (1), and a lifting device (3) is in sliding connection with the guide rail (2). The high-speed and heavy-duty truss mechanical arm is characterized in that two upper roller sets (5) and two lower roller sets (6) are symmetrically arranged on a base (4) of the lifting device (3), each roller set is composed of two rollers (7), every two rollers (7) are clamped on two sides of the guide rail (2), the upper roller sets (5) make contact with the upper portion of the guide rail (2), and the lower roller sets (6) make contact with the lower portion of the guide rail (2). The high-speed and heavy-duty truss mechanical arm is simple in structure, ingenious in design, and capable of achieving high-speed movement in the heave-duty condition. Besides, accurate positioning of the mechanical arm can be guaranteed.

Description

technical field [0001] The invention relates to a manipulator structure, in particular to a high-speed heavy-duty truss manipulator. Background technique [0002] With the continuous development of the automated production industry, more and more industrial production activities use manipulators to pick and place workpieces. The manipulator has the advantages of accurate movement, fast production tempo, labor saving, and cost control. The traditional truss manipulator includes a The beam is slidingly connected with a lifting device through a slide rail. The lifting device is equipped with a manipulator, which uses the combination of lateral movement and longitudinal movement to realize the grabbing, moving and placing actions of the manipulator. However, the defects of the traditional truss manipulator are : Between the lifting device and the slide rail, a plurality of balls arranged in the slide rail are used as the sliding parts. If the heavy load is moved, on the one hand...

[0002] With the continuous development of the automated production industry, more and more industrial production activities use manipulators to pick and place workpieces. The manipulator has the advantages of accurate movement, fast production tempo, labor saving, and cost control. The traditional truss manipulator includes a The beam is slidingly connected with a lifting device through a slide rail. The lifting device is equipped with a manipulator, which uses the combination of lateral movement and longitudinal movement to realize the grabbing, moving and placing actions of the manipulator. However, the defects of the traditional truss manipulator are : Between the lifting device and the slide rail, a plurality of balls arranged in the slide rail are used as the sliding parts. If the heavy load is moved, on the one hand, the balls may be damaged, resulting in the situation that the horizontal movement cannot be achieved, and on the other hand, it cannot be realized The rapid movement affects the production beat; at the same time, in order to ensure the accuracy of the manipulator's taking and taking action, there are also bolts that can adjust the distance and parallelism between the beam and the slide rail. However, this adjustment structure is relatively simple and cannot be adjusted after adjustment. To achieve positioning, it is easy to deviate due to vibration during the work process
