Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Referring to FIGS. 1 to 4: an end face tooth ejection device comprises a sleeve 1 and a thimble 3 arranged in the sleeve, wherein one end of the thimble 3 extends out of the sleeve 1, and the other end of the thimble is connected with a driving mechanism.

In this embodiment, the sleeve is hollow, and one end of the sleeve is closed and cylindrical, and a thimble is inserted into the hollow cavity of the sleeve, and one end of the thimble is cylindrical and defined as a cylindrical end 4, and the other end of the thimble is conical and defined as a conical end 6, and the cylindrical end of the thimble is inserted into the sleeve, and the conical end extends out of the sleeve.

The workpiece is divided into a tail end and a processing end, the tail end is in contact with the ejector pin, and the processing end can form end face teeth under the action of a processing device arranged outside the machine tool. The conical end part is arranged to facilitate subsequent processing of the workpiece, the center of the tail end of the workpiece is provided with a small hole, and the conical end part can be inserted into the center hole of the workpiece, so that the tail end of the workpiece cannot shake during processing, and the cylindrical end of the workpiece is prevented from sagging.

In this embodiment, the cylinder end is connected to a driving mechanism (not shown), the driving mechanism is a single-acting cylinder, specifically, a single-acting spring return cylinder, one end of the cylinder is driven by compressed air, the other end of the cylinder is communicated with the atmosphere, and the return is driven by a spring and can be automatically returned. The single-acting spring return cylinder is available, and can be a single-acting spring return cylinder of a brand AirTac/Add passenger, or other types meeting the requirements in the market.

The single-acting spring reset cylinder can be arranged at the closed end of the sleeve, and a piston rod of the single-acting spring reset cylinder is fixedly connected with the cylindrical end of the thimble, so that the thimble can move along with the operation of the piston rod. The switch of the single-acting spring reset cylinder is pulled out from the closed end of the sleeve through an electric wire, and the switch is arranged outside, so that the operation of workers is facilitated. And when the switch is turned on, the piston rod moves forwards to drive the thimble to move forwards, and then the thimble resets under the action of the spring to wait for the next turn-on.

In this embodiment, a baffle plate is arranged on one side of the conical end of the thimble, which is close to the sleeve, the baffle plate is preferably a circular baffle plate and is fixedly arranged on the thimble, and the diameter size of the baffle plate is larger than the size of the cavity in the sleeve. The setting of baffle is for follow-up when installing ejecting device on the lathe, and the thimble can be the back-and-forth movement in the lathe, and in order to avoid the direct and inside contact of lathe of circular cone end, and set up the baffle for inside the butt lathe, be unlikely to the thimble and rock in the lathe.

In this embodiment, the ejector is mounted on a machine tool, one end of the machine tool is provided with a position where the ejector can be mounted, and the position is defined as an ejector area, the other end of the machine tool is provided with an inlet hole for inserting the workpiece 7, and the inlet hole is defined as a workpiece processing area, and the ejector area is communicated with the workpiece processing area.
