Description

[Detailed explanation of the idea] The present invention relates to a grinding wheel adjustment device.

A flat implanted blade at least partially formed of a hard metal or a metal containing diamond and has a regular polygonal shape, a plurality of blade parts formed on the implanted blade, and a pivot means whose axis passes through the center of the implanted blade. The invention is particularly relevant to a grinding wheel adjusting device comprising: a clamping means for holding the implant against rotation; a pivot means and a support means to which the implant is fixed via the clamping means.

The use of cutting tools having triangular or circular inserts with pivot pins protruding from a support surface in accordance with conventional tick cutting or grinding techniques is now widespread.

In this case, the blade is fixed in a desired position by tightening.

1. It is known to use a regular polygonal, particularly triangular, implanted blade, and in this case, the implanted blade has a plurality of blade parts that can be switched and used.

To switch these blades with respect to the operating position, it is only necessary to rotate the blade about the pivot pin, without having to remove the blade from the support means.

When using this type of cutting tool device for the purpose of adjusting the force of the grinding wheel (in other words, when using the grinder for cutting work), especially in line with the grinding wheel L- for precision grinding machines, it is necessary to The blade must be set in an angularly fixed position.

Therefore, especially when switching blades, the implant must be placed in a predetermined position using a specific tool before the implant is finally fixed by tightening.

Given the relatively small size of the implant, such preliminary positioning operations are particularly time-consuming and cumbersome.

The objective of the present invention is to eliminate the need for such preliminary placement operations.

To achieve this, the device according to the invention is characterized in that the support means is provided with automatic placement means for automatically placing the implant blade in a predetermined angular position.

The automatic placement means includes a slider that slides in the axial direction within the support means or a sliding member having an equivalent function, and a spring that contacts the slider and elastically presses the slider against at least one side of the implant. It consists of

Therefore, the slider can be retracted by this elastic action, and it is possible to arrange the implanted blade on the support means and rotate the implanted blade around the pivot means for the purpose of switching the blade. It becomes.

When you release this spring-loaded slider,
The implant is automatically placed at a predetermined corner position.

Embodiments of the present invention will be described below based on the drawings.

The illustrated device has a body 1 . In this example,
The body 1 has a Morse taper 1a formed on its outer surface.

However, the body 1 may be formed in other shapes, for example, in the same cylindrical shape, as necessary.

A flat surface 2 is formed on the body 1 as a support surface for the implanted blade 3 for grinding.

The blade 3 has an equilateral triangular shape, and has blade parts 3a and 3 at three locations.
b, has 3o.

The insert 3 is constituted by, for example, an upper plate containing sintered diamond powder fixed to a base of ditungsten carbide, as is known in the art.

The base is provided with a pivot pin 4, which is configured to fit into a cylindrical hole provided in the body 1.

The implant 3 is held in place on the plane 2 via two lateral pressing jaws 5 and fixed by screws 8.

A through hole is formed in the body 1 along the axial direction, and a slider 9, a coil spring 10, and a rear screw 11 are housed therein.

Of these, the rear screw 11 is connected and fixed to the tapped portion of the through hole, and the slider 9 is fixed at the operating end of the device by a coil spring 10 disposed between the slider 9 and the rear screw 11. It is energized towards the direction.

Further, the slider 9 has a front portion 12 formed into a fork shape as shown in the figure, and has two front end portions 12a, 12 branched into two.
b. In the vicinity of two adjacent apex angles of the implanted blade 3, the implanted blade 3
touches one side of the

When the implant blade 3 is not attached, the front part 12 of the slider 9 abuts the screw 8 at its central recess, and therefore the screw 8
functions as a stopper.

The front part 12 of the slider 9 further comprises a row of shoulders 13,14.

A predetermined tool can be engaged with these shoulders 13 and 14, and when this tool is operated, the slider 9 is pushed back, and during that time, the implant blade 3 is placed in the mounting position and the implant blade 3 is rotated. It is now possible to do so.

To place the implant blade 3 in the mounting position, turn the screw 8 and tighten the jaw 5.
Perform this at a sufficient distance from the horizontal direction 2 of the implanted blade support.

However, turn the screw 8 as far as possible so that it does not come off. Also, Uekami 3
The blade section can be switched by simply loosening the jaw 5.

When the tool is released and the front part 12 of the slider 9 is released, the front part 12 automatically arranges the implant blade 3 to a predetermined angular position.

Specifically, even if the insert blade 3 is initially aligned from a predetermined corner position, both front ends 12a.

At a predetermined angular position 1 where both 12b contact one side of the insert 3 and press it in the same manner, the front portion 12 rotates the insert 3 by the biasing force of the coil spring 10.

Therefore, the graft 3 can be mounted at a desired position by simply tightening the jaws 5.

Of course, the device of the present invention uses the front part 12 of the slider 9 formed in a fork shape and the implanted blade 3 formed in a triangular shape,
It is not limited.

In fact, the implant 3 may have any suitable regular polygonal shape.

For example, a square blade is used as the implant blade 3, and a notch consisting of two planes is provided at the operating end of the slider 9,
It is also possible to configure the implant blade 3 to engage with this notch.

Further, the implant blade 3 may be provided with a through hole, and the pivot pin 4 may be passed through the hole or fixed to the hole.

Alternatively, the pivot pin 4 may be configured integrally with the support portion of the device, and a through hole may be provided in the implant blade, and the pivot pin 4 may be fitted into the through hole.
