The purpose is achieved, the utility model adopts the following technical proposal: an end mill comprises an installation rod, a cutter bar, a cutter head and a rod length adjusting mechanism, wherein the rod length adjusting mechanism comprises a connecting cylinder, a hoop, a nut and a screw rod; the lower extreme and the cutter arbor of installation pole are connected, the cutter arbor is equipped with the mounting groove, be equipped with connecting cylinder and nut in the mounting groove, the nut is connected with the lower extreme of connecting cylinder to the screw thread suit is in the outside of screw rod, the upper end setting of screw rod is in the connecting cylinder to the lower extreme is connected with the tool bit, and the outside cover of nut is equipped with the clamp, the clamp setting is on the cutter arbor and the regulation end setting of clamp is in the outside of cutter arbor.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model adjusts the use length between the tool bit and the tool bar through the bar length adjusting mechanism to meet the processing requirements of different hole depths, thereby reducing the production cost;
2. the utility model can avoid the problem of repeatedly debugging the distance between the tool bit and the workpiece when in use by arranging the rod length adjusting mechanism, so that the use is more convenient;
3. the utility model discloses be equipped with a plurality of spring leafs between cutter arbor and the tool bit, improved the stability of using, increase the radiating effect simultaneously.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.
An end mill comprises an installation rod 1, a cutter bar 2, a cutter head 9 and a rod length adjusting mechanism, wherein the rod length adjusting mechanism comprises a connecting cylinder 4, a clamp 6, a nut 7 and a screw 8; the upper end of installation pole 1 and the drive shaft connection of lathe to the lower extreme is connected with cutter arbor 2, cutter arbor 2 is equipped with the mounting groove along its axial, be equipped with connecting cylinder 4 and nut 7 along the 2 axial settings of cutter arbor in the mounting groove, nut 7 passes through the bearing and is connected with the lower extreme rotation of connecting cylinder 4 to screw thread suit is in the outside of screw rod 8, the upper end setting of screw rod 8 is in connecting cylinder 4 to the lower extreme rotates with tool bit 9 to be connected, and the outside cover of nut 7 is equipped with clamp 6, clamp 6 sets up on cutter arbor 2 and the regulation end of clamp 6 sets up in the outside of cutter arbor 2, and the lower extreme of the 2 inner walls of cutter arbor is equipped with the ring channel, the outer wall that the cutter arbor 2 was run through to the ring channel is equipped with the through-hole, clamp 6 is placed in the ring channel and the regulation end passes the through-hole sets up the outside at cutter arbor 2.
The upper end of the screw rod 8 is elastically connected with the groove top surface of the mounting groove through the spring 3, and vibration of the screw rod 8 is reduced.
A rubber pad 5 is arranged between the connecting cylinder 4 and the cutter bar 2, so that the connecting cylinder 4 is prevented from being in hard contact with the cutter bar 2.
Be equipped with rubber pad 5 between nut 7 and the cutter arbor 2, 6 suits of clamp are in the outside of rubber pad 5, improve the frictional force between clamp 6 and the nut 7 through rubber pad 5, improve the stability of using.
A plurality of spring pieces 10 are uniformly distributed between the cutter bar 2 and the cutter head 9 along the circumferential direction of the cutter bar 2, so that the use stability is improved, and the heat dissipation effect is improved.
Every adjacent two all be equipped with the filter screen between the spring leaf 10, the upper end and the cutter arbor 2 of filter screen are connected to the lower extreme is connected with tool bit 9, avoids the sweeps to get into between cutter arbor 2 and the tool bit 9, and the influence regulating lever is long.
When the length of the rod needs to be adjusted, the screw rod 8 is directly pushed and pulled, the nut 7 is driven to rotate by the movement of the screw rod 8, and after the required position is adjusted, the nut 7 is clamped by the hoop 6, so that the fixation of the position of the nut 7 and the position of the cutter bar 2 can be realized, namely the position of the screw rod 8 is limited.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
