Hole depth detecting device

Abstract

The invention discloses a hole depth detecting device. The device comprises a detecting platform. The detecting platform is provided with a guide rail. The front end of the guide rail is provided witha sliding table in a sliding mode, and the rear end of the guide rail is provided with a limiting plate. A V-shaped frame for bearing workpiece to be detected is arranged between the sliding table and the limiting plate. The guide rail, the sliding table, the V-shaped frame and the limiting plate are arranged on the same straight line. A detecting rod and a detector are arranged on the sliding table, wherein the detecting rod can stretch into a hole of the workpiece to be detected, and the detector can sense the pressure on the end surface of the workpiece to be detected to output a depth value. When the workpiece requires hole depth detection, detecting personnel can place the workpiece to be detected on the V-shaped frame, and then push the sliding table to slide along the guide rail inthe direction of the workpiece till the rear end of the workpiece abuts against the limiting plate. At the moment, the pressure on the end surface of the workpiece to be detected can be sensed by thedetector which then outputs the depth value. Automatic detection of the threaded sleeve hole depth can be easily achieved, the labor intensity of the detecting personnel is effectively reduced, and the detection efficiency is improved.

Description

Technical field [0001] The invention relates to the field of detection equipment, and more specifically, to a channel depth detection device. Background technique [0002] Wind turbine refers to a device that can convert the kinetic energy of the wind into mechanical kinetic energy, and then convert the mechanical energy into electric kinetic energy. The principle of wind power generation is to use the wind to drive the windmill blades to rotate, and then increase the speed of rotation through a speed increaser to promote the generator to generate electricity. According to the current windmill technology, power generation can be started at a breeze speed of about three meters per second (the degree of breeze); and wind power generation does not require fuel, nor does it produce radiation or air pollution. Therefore, it is more and more widely used. A wind turbine generally includes three parts: a wind wheel, a generator and an iron tower. The wind wheel is an important componen...

Problems solved by technology

Since the two ends of these screw sleeves often need to be assembled with different parts, the depth requirements of the screw sleeve channel are extremely strict, and there is a lack of testing equipment for the depth of the screw sleeve channel in the prior art, and the channel depth of the screw sleeve often needs to be manually detected. , therefore, the detection accuracy is easily affected by the proficiency of the inspectors. At the same time, the labor intensity of the inspectors is extremely high, and the detection efficiency is extremely low.
