Abstract
The invention discloses an induction type bearing grinder tailstock. The induction type bearing grinder tailstock comprises a tailstock box, a pretensioner, an ejector pin and position sensors. The pretensioner is arranged at the front end of the tailstock box and is annular. A pretensioning block is arranged at the inner end of the pretensioner. The tail end of the pretensioning block is in the cambered surface shape. The ejector pin is installed at the inner end of the pretensioner. A position sensing ring is arranged at the outer end of the pretensioner and installed at the front end of the tailstock box as well. The four position sensors are installed at the upper end of the position sensing ring. According to the direction of the position sensors, the position sensors point to the front end of the ejector pin. A set of guide rail sliding blocks are arranged at the bottom end of the tailstock box. According to the induction type bearing grinder tailstock, a motor at the upper end is used for controlling the position of the tailstock on a guide rail. Through the sensors installed on the position sensing ring at the front end of the tailstock box, the front end of the ejector pin is induced concentratedly, so that the ejector pin stops automatically when close to a workpiece, automatic locating is achieved, and thus a whole grinder becomes safe and efficient.
Description
Technical field
The present invention relates to tail seat of grinding machine field, be specially a kind of vicarious bearing grinder tailstock.
Background technology
The inside and outside circle polishing operation of bearing is generally adopted cylindrical centreless-type grinder and utilizes the cylindrical of sand wheel set bearing workpiece of high speed rotating to carry out grinding, makes the inside and outside circle of bearing reach the required standards.Grinding machine is when the longer or diameter of processing is compared with group workpiece, for reducing workpiece deformation, adopts folder one top to process more, at this time will use tailstock, be contained in top tight workpiece above tailstock top, it is prevented that workpiece can't clip because having grown and falls down.So when the workpiece of overlength is processed by tailstock, it is possible to play certain supporting role, it is prevented that workpiece disalignment under the effect of cutter can not be processed too far.
Generation is at present all manually control artificially when tailstock position, sometimes frequently results in work efficiency slow, or fix insecure etc., once can bring great safety problem.
Summary of the invention
It is an object of the invention to provide a kind of vicarious bearing grinder tailstock, by being arranged on the induction apparatus on tailstock case front position inductance loop, concentrate and thimble front end is sensed, thus stopping voluntarily when thimble is close to workpiece, with the problem solving to propose in above-mentioned background technology.

Preferably, described outer sleeve upper end is installed with an oil sealing draw ring.
Preferably, described outer sleeve the inner arranges a push rod.
Preferably, described tailstock case upper end is installed with a motor, and its motor is connected with tailstock case by the transporter of rear end.
Compared with prior art, the invention has the beneficial effects as follows: the present invention utilizes the Motor Control tailstock of upper end position on guide rail, by being arranged on the induction apparatus on tailstock case front position inductance loop, concentrate and thimble front end is sensed, thus stopping voluntarily when thimble is close to workpiece, accomplish to position voluntarily, so that whole grinding machine becomes safe efficient.
