Embodiment

[0027] A position detection device, wherein the main frame is the shell 10 . The adjustment bracket 8 is fixed on the casing 10 by two position adjustment screws 9, on which the metal sensor 1 and two guide rails 6 are derived and fixed, and the guide rails 6 are symmetrically distributed on both sides of the metal sensor 1. A precision conversion unit 3 is installed in the guide rail 6 , and a precision conversion unit spring 7 is installed between the precision conversion unit 3 and the adjustment bracket 8 to provide the restoring force for the forced movement of the precision conversion unit 3 . The detection rod 2 is a bridge for the whole mechanism to contact and sense the parts to be tested, one end of which is fixed to the housing 10 by the detection rod return spring 11, and the other end is limited by the limit mechanism 12 in the direction of movement, and the leakage of the contact with the product Some parts can be deformed according to structural requirements, no...

Abstract

The invention relates to a detection device, which belongs to the field of quality detection equipment, in particular to a position detection device. It includes: a metal sensor, a detection rod, and also includes: an accuracy conversion unit, which is arranged between the metal sensor and the detection rod, and the position of the accuracy conversion unit located in the axial direction of the metal sensor is provided with a conversion unit protrusion, the The detection rod is provided with a detection rod protrusion matching with the conversion unit protrusion, and when the detection rod reciprocates vertically, the conversion unit protrusion can drive the precision conversion unit under the drive of the detection rod protrusion reciprocating motion in the horizontal direction. The device has high detection precision, adjustable detection precision, low equipment cost and wider application range.

Description

technical field [0001] The invention relates to a detection device, which belongs to the field of quality detection equipment, in particular to a position detection device. Background technique [0002] For the automotive lighting industry, many parts related to body positioning, such as positioning points, positioning bolts or other key assembly parts related to the process, require effective Poka-Yoke or automatic detection during the assembly process or after assembly Control to ensure its reliable quality performance on the client side. [0003] However, for process control, detection stability and equipment / mechanism cost are two factors that must be considered at the same time. A system with poor stability is more worrying for mass production than a 100% failure mechanism, and a system that is 100% stable but requires high investment is bound to be poorly promoted because it hinders the company's normal profitability. Therefore, developing an economical and stable de...
