High pressure resistant cylinder with approach switch

Abstract

The invention discloses a high pressure resistant cylinder with an approach switch, which comprises a cylinder (4), a front cover (3), a front air inlet (16), a piston rod (1), a buffer cover (5), a piston (6), a buffer nut (7), a back cover (8) and a back air inlet (17), and is characterized in that the front cover (3) and the back cover (8) are respectively connected with the approach switch, the front cover (3) is connected with a front gland (13), the back cover (8) is connected with a back gland (13'), a sealed reversing chamber is respectively formed between the front cover (3) and the front gland (13) and between the back cover (8) and the back gland (13'), an inductive guide rod is respectively arranged in each sealed reserving chamber, and air holes are respectively arranged in the front cover (3) and the back cover (8), and are communicated with the sealed reserving chambers. According to the invention, the high pressure resistant cylinder can automatically reverse and stop, is more conveniently started, and more accurately controlled, so that the total cost of the cylinder is greatly reduced. The high pressure resistant cylinder has good cost performance in the market competition, and can be widely applied in the field of automation.

Description

[0001] Technical field: [0002] The present invention relates to a cylinder, in particular to a high-pressure resistant cylinder with a proximity switch, which is mainly used in engineering, metallurgy, mining, machine tools, chemical industry, textile and Printing and other automation fields. Background technique: [0003] Some automation fields require a cylinder with a proximity switch, and it also needs to have a good buffer effect, so that the impact on the front and rear covers of the cylinder can be minimized when the piston runs to the end, and the impact on the connecting parts of the whole machine can also be reduced. . At present, the cylinder with a proximity switch and a buffer is relatively large in size and heavy, and its piston is very wide and complex in shape, and it is troublesome to process; it is also necessary to process a deep induction groove on the front and rear covers to act as a piston. When running to the end, the piston enters the sensing ran...

Problems solved by technology

At present, the cylinder with a proximity switch and a buffer is relatively large in size and heavy, and its piston is very wide and complex in shape, and it is troublesome to process; it is also necessary to process a deep induction groove on the front and rear covers to act as a piston. When running to the end, the piston enters the sensing range of the proximity switch, and the proximity switch sends a signal to control the reciprocating motion of the cylinder. Such a structure is quite uneconomical in cost, and in this structure, the high-pressure cylinder needs to use a high-pressure-resistant proximity switch. , the high-voltage proximity switch is more than five times the price of the ordinary proximity switch, and each high-voltage proximity switch needs more than 1,000 yuan, which greatly increases the cost of the cylinder and makes the product at a disadvantage in the market competition
