Pneumatic tongs for feeding and discharging of crankshafts

Abstract

The invention discloses pneumatic tongs for feeding and discharging of crankshafts. The pneumatic tongs comprise a machine frame, mechanical tongs, a cylinder, a left guide rail, a left rack, a gear, a right rack and a right guide rail, wherein the mechanical tongs, the cylinder, the left guide rail, the left rack, the gear, the right rack and the right guide rail are mounted on the machine frame. The mechanical tongs comprise a front grab finger set and a rear grab finger set which are symmetrically arranged front and back. The front grab finger set and the rear grab finger set each comprise multiple grab fingers arranged in the left-right direction. The rear grab finger set is fixedly connected to an output shaft of the cylinder through a rear arm, the rear arm is fixedly connected with the left rack, and the left rack is connected to the left guide rail through multiple first sliding blocks. The left rack and the right rack are both horizontally arranged, and the left rack is connected with the right rack through the gear. The front grab finger set is fixedly connected to the right rack through a front arm, and the right rack is connected to the right guide rail through multiple second sliding blocks. Compared with the prior art, the pneumatic tongs are more complete in structure function, more accurate in control and capable of being well adaptive to feeding and discharging of shaft type parts, such as the automobile crankshafts, with phase requirements.

Description

technical field [0001] The invention belongs to the field of feeding equipment, and more specifically relates to a pneumatic gripper for crankshaft loading and unloading. Background technique [0002] As an important part of the car engine, the crankshaft's rotation is the power source of the engine and the source power of the entire mechanical system, so it plays a pivotal role in the car transmission system. Because of this, its processing and production requirements are very high, and its processing technology requirements are also very high. However, the manual operation and manual feeding production methods in the domestic production process can no longer meet the needs of this industry. The automation of robots in crankshaft processing Apps are created from this. In the process of realizing the automatic machining of crankshafts, automatic loading and unloading is one of the key functions. The truss-type manipulator will become the mainstream auxiliary equipment of in...

Problems solved by technology

[0004] Disadvantages of currently used manipulators: the opening of the gripper part is V-shaped, driven by the hinge linkage mechanism, when the object is clamped, because the opening surface of the gripper touches the object obliquely, there is a force outward, and it is converted to the force of the opening surface The force changes with the displacement of the driving part, so that the object cannot be clamped stably, and it is only suitable for a sm
