Stitch needle-bending tool special for wheel speed sensor

Abstract

The invention relates to a stitch needle-bending tool special for a wheel speed sensor. The tool comprises a workbench, a first needle-bending component, a second needle-bending component and a workpiece positioning head, wherein the first needle-bending component, the second needle-bending component and the workpiece positioning head are arranged on the workbench; the first needle-bending component is arranged on the rear side of the workpiece positioning head; the second needle-bending component is arranged on the right side of the workpiece positioning head. Compared with the background technology, the tool has the advantages of simple structure, convenience in manufacturing, safety, reliability and high working efficiency; a sensor inner core is positioned on the workpiece positioning head, and a bending process is sequentially performed on two plugging needles extending out of the sensor inner core; the needle-bending components, such as a side needle bending arm, a top needle bending roller and a top needle baffle sheet are ingenious in manufacturing, and after the needle bending process is finished, a workpiece and the bent inserting needles are not scratched and damaged; the tool is suitable for batch processing and high in processing precision, and the product rejection rate is effectively reduced; a double-touch switch is adopted, and the needle-bending tool can be started by touch by the two hands of a worker, so that the two hands of the worker are enabled to depart from the tool, and the personal safety of the worker is guaranteed.

Description

Technical field [0001] The invention relates to an auxiliary processing tool, in particular to a special needle bent needle tool for a wheel speed sensor. Background technique [0002] A wheel speed sensor in the prior art, a passive wheel speed sensor, includes a housing and a sensor core. The sensor core is located in the housing, and the bottom of the sensor core is connected to the bottom of the housing. The sensor core includes a coil , Pin and skeleton, the axial side of the skeleton is provided with a coil on the radial outer side, two pins are encapsulated on the side wall on the other side of the skeleton axis, and the two ends of the pin are separated from the radial side wall of the skeleton and The axial side wall protrudes out. The coils and pins on the inner core and the skeleton are all injection-molded and packaged in the mold as a whole. In order to facilitate packaging and demolding after packaging, the pins respectively extend from the radial and top of the pa...

Problems solved by technology

At present, the bending needle is mainly bent manually, which is not only time-consuming and laborious, and the bending requirements are difficult to guarantee, but also the efficiency is extremely low, which does not meet the needs of mass processing and production; there are also simple bending tools for the bending process, the tooling The bending needle is bent by pushing the bending parts manually, and the bending by human power has high requirements on the operation of the workers and is prone to fatigue; and if the bending tooling is not operated carefully, once the bending does not meet the requirements If the second bending is carried out, the product will easily be scrapped; moreover, since there are two different bending positions, two different bending processes and bending tools are required, and the production efficiency obviously cannot be improved.
