Outer diameter and hook length detecting device of commutator

Abstract

The invention discloses an outer diameter and hook length detecting device of a commutator. The detecting device comprises a detecting platform; foot pads are arranged at the bottom of the detecting platform; a light-sensitive plate is arranged t the top of the detecting platform; a positioning detection column is arranged at the top of the light-sensitive plate; an adjusting switch is arranged atthe top of the positioning detection column; and a locking button is arranged at the top of the adjusting switch. A groove is formed in one side of the detecting platform; a lead screw is arranged inthe groove; one end of the lead screw penetrates one side of the detecting platform and is fixedly connected with one end of a rotating shaft I arranged at a motor; a lead screw sleeve sleeves the middle part of the lead screw; a sliding plate is arranged at one side of the lead screw sleeve; and one end of the sliding plate penetrates the groove and extends to the outer side of the groove to befixedly connected with the bottom of a bracket. A tooth groove is formed in the upper part of one side of the bracket. The detecting device has the following beneficial effects: the whole process is simple in operation; the efficiency and detection accuracy are high; and time is saved.

Description

technical field [0001] The invention relates to the technical field of commutators, in particular to a detection device for the outer diameter of a commutator and the length of a hook. Background technique [0002] The commutator is a part of the DC permanent magnet series motor in order to allow the motor to continue to rotate. The structure of the commutator is surrounded by several contact pieces, which are respectively connected to each tap on the rotor. The two electrodes connected to the outside are called brushes, and only two of them are in contact at the same time. There are many structures of commutators, among which the hook commutator gets its name from the hook on the top of the copper bar. For the hook commutator, the key detection indicators include the outer diameter and the length of the hook, which is mainly to detect the height of the lowest point of the hook to indirectly achieve the purpose of detection. The current outer diameter detection is mostly me...

Problems solved by technology

For the hook commutator, the key detection indicators include the outer diameter and the length of the hook, which is mainly to detect the height of the lowest point of the hook to indirectly achieve the purpose of detection. The current outer diameter detection is mostly measured by a vernier caliper. The length dimension detection is measured by a height gauge, the operation is cumbersome, inefficient, and a lot of time wasted
