CS240307B1 - Cone clamping surface clamping device - Google Patents

Abstract

The device for clamping components with a conical clamping surface allows clamping workpieces - bearing rings of tapered roller bearings by a pre-forged conical surface for surface treatment and both parts simultaneously. The advantage of the device is the reduction of scrap mainly in forgings due to the use of the conical surface as a technological basis.

Description

Component clamping device · with tapered clamping surface enables clamping of workpieces - tapered roller bearing rings by forging a tapered surface for machining the surface and both faces simultaneously. The advantage of the device is the reduction of rejects mainly in forgings due to the use of the conical surface as a technological base.

SBRJ.

The invention relates to a device for clamping parts behind a conical clamping surface so that it allows the conical surface to form a technological base and allows machining of parts from three sides.

Previously known clamping devices do not allow the workpiece to be clamped. beyond the tapered bore, this surface was eventually used to center the workpiece, which greatly limited the use of progressive technology with multiple surface machining at the same time, the use of associated tools and the like.

The above-mentioned drawbacks are eliminated by the clamping device according to the invention, which is based on the fact that in the head mounted on the loader arm are inserted sliding bodies with pulleys mounted on pins, the workpiece is pressed by springs by means of conical mandrel bodies.

An advantage of the device according to the invention is that the device allows the bearing rings to be clamped by the forged tapered surface for machining the surface and both faces simultaneously, using more progressive technology. Another advantage is the removal of rejects from the use of the conical surface as a technological base.

An example of the solution of the clamping device according to the invention is shown in the attached drawings. Fig. 1 shows a side view, FIG. 2 is a front view and FIG. 3 shows a plan view of the device. Fig. 1 the head 2 is connected to the loader arm 5, insertion bodies 7 with pulleys 3 mounted on the pins 4 are inserted into the holes of the head 2, the workpiece 6 is pressed by springs 8 by means of the bodies 7 on the conical mandrel 1.

The device works as follows: in the basic position of the device into the head 2 the workpiece 6 is inserted from the magazine, from this position the loader with the head 2 and the workpiece 6 is moved into the spindle and tapered axis 1 and the system is pushed on the tapered pin 1. With the head 2, it remains in this position during machining as the workpiece clamp 6. After the machining is finished, the loader with the head 2 and the workpiece 8 is moved in the axial direction into the removal area where the removal device takes over the workpiece. The use of the equipment is envisaged in series, mass and automated production.
