Abstract

The invention relates to a gap eliminating type magnetizing clamp, comprising a sliding block, a support, and an extrusion piece. The support has a cavity for an input shaft to extend; grooves matched with the sliding block are arranged at the both ends of the upper end of the support; the outer end surface of the sliding block is inclined inwards from bottom to top; the extrusion piece is supported at the upper end of the outer edge surface of the sliding block; the sliding block approaches to the middle by extruding the extrusion piece downwards, so that a mechanical flat opening on the input shaft is clamped; and the inner edge surface of the sliding block at a clamping state is tightly adhered to a limiting plane of the mechanical flat opening. The invention provides the magnetizing clamp can automatically eliminate a gap between a work piece and the magnetizing clamp, can automatically center a phase of a magnetic ring, and is used for improving the sensor properties and ensuring the sensor consistency.

Description

technical field [0001] The invention relates to a magnetizing fixture for a magnetic coil of an EPS Hall type torque sensor. Background technique [0002] The magnetic coil, as the magnetic field generating source of the EPS Hall torque sensor, its working principle determines that the magnetic coil must be connected with the input shaft including the mechanical flat mouth as a whole, and then the magnetizing coil on the workbench will carry out the magnetic coil. For multi-pole magnetization, the NS pole center position of the magnetic coil must be aligned with the center position of the mechanical flat mouth after magnetization. [0003] Figure 1-Figure 2 It is a structural schematic diagram of a magnetic coil assembly, which includes an input shaft 11 and a magnetic coil 12 mounted on the input shaft 11. The magnetic coil 12 is magnetized by a magnetizing coil located on the workbench. After magnetization, the magnetizing coil The NS pole phase center of the magnetic co...
