Problems solved by technology
At present, the inspection of the size of such complex parts is usually carried out by using precision inspection instruments-three coordinates, but the cost of three coordinates is relatively expensive, and a specific inspection program needs to be compiled, the inspection takes a long time, and the environment of the instrument is stored. There are certain requirements for temperature and humidity, and regular maintenance is required, which further increases the production cost of the factory, and is not suitable for the process control of products at the production site at any time

The invention discloses a circulator in-hole two-pole narrow surface width detection device, which comprises a hand-held part and a measuring part. One end of the hand-held part is fixedly provided with a measuring instrument, the other end of the hand-held part is fixed with one end of the measuring part, and the other end of the measuring part is integrally provided with a guide block matched with the circulator in-hole two-pole narrow surface. The guide block is provided with a measuring mechanism used for measuring the width of the narrow surfaces of the two poles in the circulator hole, a transmission mechanism is arranged between the measuring instrument and the measuring mechanism, and the measuring instrument is connected with the measuring mechanism through the transmission mechanism. The device has the advantages that the guide blocks matched with the narrow surfaces of the two poles in the circulator hole are arranged, and the measuring mechanism, the transmission mechanism and the measuring instrument are arranged, so that the device is convenient to detect, short in detection beat, convenient to operate, accurate in measurement result and convenient to store in a production field, replaces three-coordinate detection of the widths of the two surfaces in the circulator hole, reduces the detection cost, and improves the detection efficiency.
Description
technical field [0001] The invention relates to a detection device, in particular to a detection device for the narrowest width of a circulator installation hole of a ball nut. Background technique [0002] Since the ball nut plays a vital transmission role in the automobile steering system, the part that realizes the transmission function mainly comes from the rolling of steel balls. In order to save the overall space structure of the components, the screw nut can be continuously reciprocated, which is Make the steel ball return to the starting point to continue running after running a part of the stroke, so as to realize the infinite rolling motion of the ball nut. The device that can make the steel ball run to the end and then return to the starting point is called a circulator, which can make the steel ball infinitely roll in such a narrow space between the screw nut. In order to fix the circulator, a mounting hole must be opened on the ball nut, and the size of this mo...
