Riveting point device with double air cylinders

Abstract

The invention relates to a riveting point device with double air cylinders. The riveting point device with the double air cylinders comprises platform deck and support frames, wherein the platform deck is used for bearing and fixing products, the support frames are positioned on two sides of the platform deck, each support frame is provided with an air cylinder connected in series, and the two air cylinders connected in series are arranged face to face. An L-shaped link stopper is arranged on each support frame, and a sliding block is arranged on each L-shaped link stopper. The piston rods of the air cylinders connected in series are connected the sliding blocks in a driving mode, the air cylinders connected in series drive the sliding blocks to move along the L-shaped link stopper and rivets are arranged on the sliding blocks. When the riveting point device receives strong impulse load, the precision of the rivets can be guaranteed in + / - 0.02 mm, parts related are less, design is simple, and cost is low. The sliding blocks and the L-shaped link stoppers are made of tungsten steel or other materials with a good performance, and friction coefficient less than 0.001 can be acquired through the roughness of a processing surface. The whole friction surface is in an open space, is convenient to grease, and replacing rivets or other workpiece. The riveting point device with double air cylinders is not limited by motion frequency, meets the requirements of glide pressing-in precision, high motion frequency of the air cylinders, multiple-direction strong impulse loads bearing and the like.

Description

technical field [0001] The invention relates to a double-cylinder riveting point device, which belongs to the technical field of automation equipment. Background technique [0002] High-precision, high-frequency, axially and radially loaded, non-rotary sliding riveting point mechanism, the following methods are often used in the non-standard design of light industries such as electronics: linear guide rail mechanism, double linear bearing mechanism, plate roller Chain Mechanisms and Constrained Contour Mechanisms. [0003] The four action directions of the linear guide mechanism have the same rated load, and most of the steel balls are arranged at 45°, which can maintain a low friction coefficient. The disadvantage is that an additional mechanism is required to ensure rigidity. Most ball cages are made of plastic, which affects accuracy and life. Regular maintenance is required, and the cost of purchase and use is high. [0004] In the double linear bearing mechanism, the ...

Problems solved by technology

[0006] Constrained contour mechanisms include quadrilateral, triangular, T-shaped, rectangular (or irregular rectangular), splined, etc., which are flexible in use, have small space restrictions, and most of the machining accuracy can meet the design requirements. When a heavy load is applied, the machining accuracy will be difficult and the cost will increase

In addition, it is easy to wear and is not suitable for long-stroke sliding
