Pin shaft parallel type size sensor conversion structure

Abstract

The invention discloses a big sensor and small sensor converting structure with parallel pin shafts. The big sensor and small sensor converting structure with the parallel pin shafts comprises a big sensor, a big connector, a small sensor, a small connector and a tested workpiece installation base, wherein one side of the big sensor is fixed, the left end of the big connector is in threaded connection with the big sensor, an installation wall is arranged on the big connector, the small sensor is installed on the installation wall of the big connector, the left end of the small connector is in threaded connection with the small sensor, the tested workpiece installation base is provided with a connecting plate assembly, the middle portion of the left end of the connecting plate assembly is connected with the big connector through a first pin shaft and pin hole matched structure, and the middle portion of the right end of the connecting plate assembly is connected with the small connector through a second pin shaft and pin hole matched structure. By the adoption of the big sensor and small sensor converting structure with the parallel pin shafts, in the process of testing the performance of a product, during conversion between the big sensor and the small sensor, the assembly and disassembly difficulty of disconnection and connection can be lowered, the workload for product testing is lightened, and the product testing efficiency is improved.

Description

technical field [0001] The invention relates to a pin shaft parallel size sensor conversion structure, which is mainly used for the disconnection and connection of the size sensor during the conversion of the workpiece performance test, and belongs to the field of electromechanical technology. Background technique [0002] At present, the lock-type hydraulic damper is an industrial pipeline support device, which is widely used in electricians, steel mills, and chemical plants. Before the damper is put into service, two tests involving load and speed parameters are carried out, one is the frictional resistance test at low speed, and the other is the blocking speed test under rated load. figure 1 It is a schematic diagram of the damper test system. Generally, the oil cylinder and the front seat are fixed. The tailstock is fixed on the foundation with many bolts or a pressure mechanism. The sensor is also screwed to the tailstock with several to a dozen bolts. superior. Frict...

AI Technical Summary

Problems solved by technology

Since it is very troublesome to disassemble and assemble the damper, disassemble and install the sensor and replace the tailstock, the test work is labor-intensive and the work efficiency is low

In some cases, such as regular maintenance of nuclear power plants, a large number of dampers that have been removed need to be tested, and the replacement of sensors often takes up more than one-third of the test time, which greatly affects the progress of maintenance
