The positioning device ensures the unification of the processing reference surface and the measuring reference surface and accords with the requirement of a machining principle.
Description
Technical Field
The utility model relates to a processingequipment of electro-magnet, in particular to positioner behind chuck in the electro-magnet guide sleeve processing belongs to electro-magnet processing manufacture equipment technical field.
Background
The guide sleeve of the electromagnet needs to be machined on a machine tool, when a traditional three-jaw chuck is used for clamping and positioning a threaded end, the clamping and positioning schematic diagram is shown in fig. 3, the guide sleeve is clamped in the three-jaw chuck, and the rear end of a hole in the three-jaw chuck 1 is provided with a positioning block 2, the clamping and positioning in the mode take the end face of a pipe orifice as a positioning reference, but the key size A (namely the distance taking the iron core suction surface of the inner hole of the guide sleeve as a reference) shown in fig. 2 is required to be ensured during machining in the process, so that the clamping reference surface is not uniform with the measuring reference surface; the critical dimension a may be affected by the machining tolerance of the dimension B, and the consistency and accuracy of the critical dimension a may not be guaranteed.
Disclosure of Invention
An object of the utility model is to overcome the above-mentioned problem that exists in the processing of present electro-magnet guide sleeve, provide a positioner behind chuck in the processing of electro-magnet guide sleeve.
In order to realize the purpose of the utility model, the following technical proposal is adopted: the chuck rear positioning device in the processing of the electromagnet guide sleeve comprises a three-jaw chuck, wherein the three-jaw chuck is arranged on a main shaft, a fixed seat is fixedly connected with the rear end of the three-jaw chuck, the rear part of the fixed seat is positioned in a main shaft hole, a middle hole is formed in the fixed seat, the diameter of the middle hole is larger than the outer diameter of the guide sleeve, a positioning shaft is fixedly connected with the center of the fixed seat, the diameter of the positioning shaft is smaller than the diameter of an inner hole of a guide sleeve pipe, the length of the positioning shaft is larger than or equal to the depth of the inner hole of the guide sleeve pipe, when the guide sleeve is loaded into the three-jaw chuck, the front end of the positioning shaft is propped against an iron core suction surface of the inner hole of the guide sleeve pipe; further, the method comprises the following steps of; the middle hole formed in the fixing seat is a stepped hole with a small hole at the rear part and a large hole at the front part, threads are processed in the small hole, the rear end of the positioning shaft is fixedly connected or integrally processed with a small-diameter tail part, the diameter of the small-diameter tail part is smaller than that of the positioning shaft, and the small-diameter tail part is screwed in the small hole through the threads.
By adopting the positioning device, during processing, the guide sleeve is arranged in the fixed seat, the bottom of the guide sleeve props against the end face of the positioning shaft, and then the three-jaw chuck clamps the excircle, so that the positioning processing of the bottom of the inner hole of the guide sleeve is realized. The processing reference surface and the measuring reference surface are unified, and the requirements of a mechanical processing principle are met; the device directly uses the iron core suction surface at the bottom of the inner hole of the guide sleeve as a clamping and positioning surface to process the threaded end, can ensure the consistency and the accuracy of the key size A of the electromagnet, and improves the production and processing precision.
