Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1-3, a worm cyclone milling head with an adjustable spiral angle comprises a carriage 1, a supporting plate 2 is arranged at the top end of the carriage 1, a motor 3 is arranged on the supporting plate 2, an output end of the motor 3 is provided with a driving wheel 4, a synchronous belt 5 is matched on the driving wheel 4, a cutter head 6 is matched at one end, away from the driving wheel 4, of the synchronous belt 5, and a through hole 7 capable of being matched with a workpiece is arranged at the axis of the cutter head 6. The cutter head 6 is rotatably connected with the sliding frame 1.

One side of the cutter head 6 is in threaded connection with three milling cutter blades 8, the number of the milling cutter blades 8 is three, the milling cutter blades are uniformly distributed along the circumferential direction of the cutter head 6, and the tool nose of each milling cutter blade 8 is aligned to a workpiece positioned in the through hole 7.

The cyclone milling head is provided with a sliding frame 1 which can be matched with a sliding rail, and the sliding rail is provided with a driving mechanism which can drive the sliding frame 1 to move on the sliding rail. The slide rail and the driving mechanism are both the existing structures of the cyclone milling machine tool, and detailed description is omitted here.

Before working, the workpiece can be arranged in the through hole 7 in a penetrating mode. The angle that can change milling cutter piece 8 to the worm to needs different demands reaches the processing technology requirement, because of this application adopts threaded connection's mode to make milling cutter piece 8 be connected with blade disc 6 to the accessible is first unscrewed then adjusts its angle, and the fixed mode of screwing again finally realizes. Furthermore, this solution also facilitates the replacement of the milling insert 8 in case of damage.

Further, the cutter head 6 comprises a rotating body 9, three thread grooves evenly distributed along the circumferential direction of the rotating body 9 are formed in one side of the rotating body 9, and fixing holes matched with the thread grooves are formed in one sides of the three milling blades 8 in a penetrating mode. The thread groove and the fixing hole can be fixed by a fastener.

Further, a rotary bearing 10 is provided between the cutter head 6 and the carriage 1. The rotation resistance of the cutter head 6 can be reduced by rotating the bearing 10, and the rotation efficiency is improved.

Furthermore, a plurality of first external teeth (not shown in the attached drawings) are uniformly distributed on the outer surface of the driving wheel 4, a groove 15 is formed in the middle of the cutter head 6, and a plurality of second external teeth (not shown in the attached drawings) are uniformly distributed in the groove 15 of the cutter head 6. The timing belt 5 is provided with third external teeth (not shown in the drawings) which can mesh with the first external teeth and the second external teeth.

The transmission of force to force can be increased by the tooth-to-tooth contact. Thereby be convenient for the efficient transmission of the rotation output of motor 3 to blade disc 6 to drive blade disc 6 and rotate.

Furthermore, one side of the cutter head 6 is provided with storage tanks 11 for storing cooling lubricating liquid, the number of the storage tanks 11 is three, and the three storage tanks 11 are respectively positioned between any two milling cutter blades 8. One side of each tank 11 is provided with a cooling and lubricating fluid outlet 12 directed towards the tip of one milling insert 8.

Cyclone milling cutter course of working all can cool off milling cutter, and traditional cooling mode mainly adopts the mode of pouring type (outer cold), and this kind of mode adopts a large amount of cutting fluids to pour into a mould and guarantees the actual processing needs in cutting area, but the processing area that lubricating fluid can't cool off can appear in this kind of lubricated cooling mode, and this kind of cooling lubrication often because lubricating fluid use amount is big, leads to processing cost height and high accuracy external thread precision to have some influence.

Because the tool tip acts on the workpiece for a long time during work, a large amount of heat can be generated by friction. The arrangement of the present application cools the cutting edge of the milling cutter blade 8, and the cooling lubricant directly acts on the machining area, thereby reducing the use of a large amount of cooling lubricant.

Further, the same communication ring 13 is integrally arranged among the three storage tanks 11, and the communication ring 13 is located at one end (i.e. the outer end) of each storage tank 11 far away from the through hole 7. Each tank 11 and the communication ring 13 are made of a material with high thermal conductivity.

By the function of the communication ring 13, the three tanks 11 can be communicated, so that the cooling lubricant in the tanks 11 can be circulated and used. In particular, the outer end of the cutter head 6 is provided with the communicating ring 13, so that the centrifugal action generated by the cutter head 6 during rotation can drive the cooling lubricant in each storage tank 11 to move towards the communicating ring 13 and the other storage tank 11, and the storage tanks 11 and the communicating ring 13 are both made of materials with high heat conductivity coefficients, so that the cutter head 6 is cooled by heat conduction.

Further, one side of the communication ring 13 is provided with an inlet (not shown in the drawings) into which a cooling lubricant can be injected, and a piston (not shown in the drawings) is interference-fitted in the inlet.

In actual use, the cooling and lubricating liquid is injected from the inlet, and the injection height is not too high, and may be referred to as the position height of the cooling and lubricating liquid outlet 12 located at the lowest position in the state shown in fig. 2. So that the cooling lubricant does not overflow. When the device works, the motor 3 drives the cutter head 6 to rotate, so that the cutter head 6 rotates. So that the cooling and lubricating fluid is rapidly dispersed in the three tanks 11 by the centrifugal action and by the gravity action through the communication ring 13. When one of the cooling and lubricating liquid outlets 12 is located at the top, the cooling and lubricating liquid in the tank 11 located at the top at this time drops down by gravity, and acts on the working portion of the blade.

Further, gaps 14 for adjusting the angle of the milling cutter blade 8 are arranged among the three storage tanks 11, the communication ring 13 and the milling cutter blade 8.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
