Description

one

The invention relates to mechanical engineering, in particular to instrumental production, and can be used for sharpening a multi-blade tool with variable angles and radial.

A device for sharpening a multi-blade tool is known, which comprises a stand with a table carrying the tool for positioning the workpiece and a grinding head with a drive mounted in a housing made in the form of a frame, spanning the fixed stand and having the ability to rotate in a vertical plane 1.

The drawbacks of the device are the non-grind sharpening of a multi-blade tool with alternating hind angles, the inability to process the radii on sharp-edged radius cutters, and also the front angle of a circular tooth on spherical balls.

The purpose of the invention is the expansion of the technological capabilities of the known device.

The goal is achieved by the fact that the fixed pillar is worn and rotatable around a vertical axis.

FIG. 1 shows the device, a general view; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a view along arrow B in FIG. one.

The device for sharpening a multi-blade tool contains a frame 1, on which a pillar 2 is rotatably mounted with the possibility of rotation around the vertical axis O-O.

On the rack 2, the corus 4 is movably mounted by the axis 3, vypoliyiny in the form of a frame covering the rack 2. Corus 4 on the rack 2 is fixed by fastener elements 10 5.

On the housing 4, the slide 6 is vertically mounted with the possibility of synchronous rotation around the horizontal axis from one end, and 15 from the other end is the drive 7 of the grinding head. The rotation of the drive 7 and the grinding head 6 is fixed by the fastening elements 8.

On the frame 1 movably mounted table 20 9, located on the side of the lifting head 6.

On the table 9 fixed fixture 10 for installation details 11.

The fixture 10 for mounting the part 11 is made with a plate 12 on which the slide 13 is movably mounted with the possibility of turning around the axis 14. On the slide is fixed the part 10 and the anvil 15.

The device operates as follows: 30 M.

The part 11, for example a sharp-cutter radius cutter, is attached to the support plate 13, after which the cutter 15 is supplied to the cutter's tooth. A grinding wheel 6 is adjusted at a time by turning it about the horizontal axis, the head G being released from the fastening elements 8 and turning around the axis at the desired angle, thereafter the actuator 7 also rotates by an angle which is equal to the angle of rotation of the grinding head 6, after which the grinding head 6 and the actuator 7 are fastened with fastening elements 8 to the body 4. The housing 4 is freed from the fastener elsmept and rotates also to the calculated angle around the axis 3, after which it is fastened with the fastening elements 5. After the final adjustment of the grinding head 6, the part 11 is brought to the grinding wheel and the machine is started, i.e. which transmits a grinding wheel through a belt drive. After that, the caliper 13 is turned around the shaft 14, i.e., the radius is sharpened on the tooth, firstly on one side of all the cutter teeth, and

then, by stirring, from the tooth, on the other hand, with each tooth alternately resting on the support 15.

When grinding a circular tooth on a spherical roller cutter, an additional rotation of the grinding head 6 is made on the front face by rotating the stand 2 around the axis O-O.
