Linear cylinder motion detection device

Abstract

The invention provides a linear oil cylinder action detection device, which includes an upper guide seat, a detection head, an air intake base, a lower guide seat and a guide rod, and the air intake base is used to pass gas required for the action detection of the oil cylinder; The upper guide seat and the lower guide seat are respectively arranged on the upper and lower ends of the air intake base to realize the conduction of gas between the air intake base and the detection head; the guide rods pass through the upper guide seat in turn from top to bottom , air intake base and lower guide seat; the detection head is arranged on the side of the upper guide seat and / or the side of the lower guide seat, and the gap between the upper guide seat and the detection head or the lower guide seat and the detection head is realized by moving the guide rod up and down. gas on and off. The invention achieves the purpose of detecting the action state of the oil cylinder without changing the external dimensions of the oil cylinder, and has the advantages of convenient production and processing, strong versatility, low development cost, short development cycle and good economy.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a linear oil cylinder motion detection device. Background technique [0002] At present, in fixtures, there are two commonly used methods for monitoring and detecting the clamping or loosening of long-stroke linear cylinders; one of which is the clamping or loosening detection function of the cylinder itself, and the other is to use a photoelectric sensor to detect the clamping or loosening of the cylinder. s position. [0003] Usually, the cylinder with its own clamping or loosening detection function is used, which has good stability and versatility. However, it is difficult to realize the integration of clamping / releasing monitoring and detection for long-stroke linear cylinders. Although it can be realized, its structure is feasible. Due to the limitation of the oil cylinder itself, when a detection device is added to the tail of the oil cylinder, its structural shape is do...

Problems solved by technology

[0003] Usually, the cylinder with its own clamping or loosening detection function is used, which has good stability and versatility. However, it is difficult to realize the integration of clamping / releasing monitoring and detection for long-stroke linear cylinders. Although it can be realized, its structure is feasible. Due to the limitation of the oil cylinder itself, when a detection device is added to the tail of the oil cylinder, its structural shape is double that of the ordinary oil cylinder, and the larger the stroke, the longer the total length of the cylinder body plus the detection device, which is not easy to discharge in actual use. cloth

[0004] For some non-standard custom-made detection devices, the clamping detection range needs to be made according to customer needs, the manufacturing cycle is long and expensive, and the detection range is fixed, which is inconvenient to adjust. Long-term movement causes poor sealing and high energy consumption ratio of detection gas , high maintenance cost
