Background

Milling cutters are cutting tools commonly used in milling machines or machining machines to perform milling operations (sometimes in other machine tools). They remove material by their fixed feed rate within the machine. Milling cutters have various shapes and sizes, and are classified into end mills, roughing end mills, face mills, and the like according to their shapes and sizes, wherein the end mills are also called end mills, which are commonly used to refer to flat bottom cutters, and also include round cutters (referred to as "ball heads") and radius cutters (referred to as "noses" or "torus"). They are typically made of high speed steel or cemented carbide and have one or more grooves. They are the most commonly used tools in vertical mills. Another type of milling cutter is a milling cutter having a length exceeding the circular arc portion greater than 1/4 circles.

The cutting edges of a general milling cutter are easily blunted after the milling cutter is used on a milling machine or a processing machine, so that the cutting edges of the milling cutter need to be reground, and the relative position of the milling cutter on a grinding machine must be adjusted according to the size of a display cutter after the milling cutter is fixed on the grinding machine due to the fact that the milling cutter has various sizes and the diameters of the milling cutters are different.

The milling cutter is fixed on the grinder to be adjusted in size, the milling cutter is usually clamped on a collet chuck for the milling cutter, the collet chuck fixed with the milling cutter is arranged at the position for adjusting the size, so as to adjust the relative position relationship between the milling cutter and the collet chuck, and then the collet chuck clamped with the milling cutter is fixed on the grinder.

Detailed Description

Referring to fig. 1 to 4, the present invention relates to a positioning device for a milling cutter grinding machine, which comprises a base 10, a holder 20 and a positioning rod 30, wherein:

the base 10 has a locking hole 11; in this embodiment, the base 10 is a base of a general grinder, and the base 10 is provided with a grinding wheel, a motor and the like of the general grinder, and the main structure thereof is the same as the conventional structure, and therefore, the description thereof is omitted.

The holder 20 has a head 21 and a bolt 22, the head 21 is disposed on the base 10, the head 21 has a fixing portion 211 and a sliding portion 212, the fixing portion 211 has a fixing hole 213 for clamping the milling cutter, the sliding portion 212 is attached to the base 10 and has a long hole 213, the bolt 22 passes through the long hole 213 and locks or releases the locking hole 11 to tighten or loosen the head 21; in the embodiment, the fixing portion 211 and the sliding portion 212 of the seat head 21 have a vertical angle θ therebetween, so that the side surface of the seat head 21 is L-shaped, and thus, when the sliding portion 212 of the seat head 21 abuts against the base 10, the fixing portion 211 stands on the base 10.

The positioning rod 30 is disposed at one side of the holder 20, the positioning rod 30 has at least one set of positioning marks 31, and the at least one set of positioning marks 31 has a plurality of steps 311 arranged along an axial direction X; in the embodiment, the positioning rod 30 is in a tapered column shape, and the positioning rod 30 has a plurality of different diameters along the axial direction X through the tapered column shape, and the steps 311 on the at least one set of positioning marks 31 are arranged along the axial direction X, so that each step 311 can be sequentially stepped or stepped down, and the at least one set of positioning marks 31 form a step shape.

Referring to fig. 3, 5 and 8, in the present embodiment, the number of the at least one set of positioning marks 31 is two, and two sets of positioning marks 31 are located at corresponding positions in the radial direction of the positioning rod 30. Therefore, when one of the positioning marks 31 is viewed from above in fig. 5 and 8, the other positioning mark 31 cannot be seen, whereas when one of the positioning marks 31 is viewed from below in fig. 8, the other positioning mark 31 cannot be seen.

Secondly, one of the two sets of positioning marks 31 is provided with the steps 311 with odd number sizes, and the other set of the positioning marks 31 is provided with the steps 311 with even number sizes, and by separating the odd number sizes from the even number sizes, the difference between the steps 311 on each set of positioning marks 31 is large, so that when a user adjusts the milling cutter to correspond to one of the steps 311, the large difference can prevent the user from corresponding errors, and the user can more quickly and accurately correspond the milling cutter to the correct size.

Furthermore, the locking hole 11 of the sliding portion 212 extends along a longitudinal direction Y, the longitudinal direction Y is perpendicular to the axial direction X, and the longitudinal direction Y is located on the plane of the sliding portion 212, and is perpendicular to the axial direction X through the longitudinal direction Y, so that when the user releases the seat bolt 22, the seat head 21 can approach or depart from the positioning rod 30 along the longitudinal direction Y.

Finally, the positioning rod 30 further has a rod seat 32, a rod body 33 and a pressing bolt 34, the rod seat 32 is fixed on the base 10, and the rod body 33 penetrates through the rod seat 32, so that the rod body 33 can move along the axial direction X in a reverse manner, and the pressing bolt 34 penetrates through the rod seat 32 and abuts against the rod body 33, and the pressing bolt 34 presses or releases the rod body 33, so that a user can firstly release the pressing bolt 34 when needing to adjust the rod body 33, and move the rod body 33 along the axial direction X to adjust the step 311 of the corresponding size, and then lock the pressing bolt 34 to fix the rod body 33.

In view of the above, the present invention provides a structure configuration and connection relationship thereof in a preferred embodiment, and the usage and effects thereof are as follows:

referring to fig. 5 to 8, when a user wants to grind a milling cutter, the size of the milling cutter to be ground can be determined. After confirming the size, the user rotates to release the fastening bolt 34, and displaces the rod body 33 along the axial direction X to face the seat head 21 of the holder 20 with the corresponding size, and then rotates the fastening bolt 34 to lock, thereby fixing the rod body 33.

At this time, the user can release the seat bolt 22 to move the seat head 21 along the longitudinal direction Y, so that the fixing portion 211 of the seat head 21 abuts against the rod body 33, since the corresponding dimension is adjusted in advance, when the seat head 21 abuts against the rod body 33, the seat head 21 can be adjusted to the most appropriate distance by the positioning mark 31 on the rod body 33, and finally, the user presses the seat bolt 22 again, thereby fixing the seat head 21.

Through the adjusting means, a user can quickly adjust the position of the seat head 21 according to the size of the milling cutter, so that the user can grind the milling cutter more conveniently, and the position of the seat head 21 is directly adjusted by the positioning rod 30, thereby greatly shortening the time for adjusting the seat head 21 in the prior art.
