Abstract
The invention relates to a milling fixture used for processing key slot in hole, comprising a support and a clamping sleeve fixed on one end of the support; one end of the support bears a connecting shaft by virtue of a bearing, the connecting shaft is protruded in the clamping sleeve, the other end of the support bears an output shaft by virtue of the bearing, the connecting shaft and the output shaft are connected by a transmission mechanism, the support is in hollow structure, and the transmission mechanism between the connecting shaft and the output shaft is arranged at the hollow part of the support. The invention overcomes that defect that a common vertical milling machine can not process key slot in hole in the prior art, by adopting the design, the milling mixture is combined with vertical milling machine, key slots in different holes can be processed, thus not only processing cost is reduced, but also size and symmetry degree of key slot can be well ensured (slot width can reach 0.02mm, symmetry can reach 0.05mm), and the invention has the advantages of compact structure, assembly convenience, high processing efficiency and strong reliability.
Description
Technical field
The present invention relates to milling of a kind of machining hole internal keyway and use anchor clamps.
Background technology
End mill is one of the widest equipment that uses in the mechanical industry, but traditional end mill all can not be processed the keyway in the hollow shaft.The processing of hollow shaft internal keyway needs slotting machine, line cutting or broaching machine, but generally can not be equipped with slotting machine, line cutting or broaching machine in the non-professional factory again, therefore can only outer association process, but the cycle of cooperation processing can not guarantee, moreover product quality is difficult to control, processing charges height.Therefore, how on traditional end mill, to add special-purpose anchor clamps and make it to be applicable to that the processing of female keyway is the problem that presses for solution.
Summary of the invention
In order to overcome the problem that common end mill in the prior art can not be processed female keyway, the invention provides milling of a kind of machining hole internal keyway and use anchor clamps, this machining hole internal keyway mill compact conformation with anchor clamps, easy to assembly, with end mill in conjunction with after can process the keyway in the different holes.
The technical solution adopted for the present invention to solve the technical problems is: comprise support and the gripping sleeve that is fixed on support one end, an end supports connecting axle by bearing on support, connecting axle is given prominence in gripping sleeve, the other end supports output shaft by bearing on the support, links to each other by transmission mechanism between connecting axle and the output shaft.
Support is a hollow-core construction, and the transmission mechanism between connecting axle and the output shaft is arranged on the hollow part of support.
Support is linked to each other by adjustable docking mechanism with the right support body by the left socle body and constitutes, and output shaft is bearing on the left socle body, and connecting axle is bearing on the right support body, and the transmission mechanism between connecting axle and the output shaft is the belt pulley transmission.
Adjustable docking mechanism comprises the double thread connecting rod, and the direction of two screw threads is opposite on the double thread connecting rod, and the two ends of double thread connecting rod are screwed in respectively on left socle body and the right support body.
Be provided with at the left socle body and be provided with long slot bore on attachment screw, the right support body and cooperatively interact and be connected and fixed.
The present invention is by above-mentioned specific design, with end mill in conjunction with after can process the keyway in the different holes, not only reduced processing charges, and keyway size and symmetry can both finely guarantee that also (groove width can reach 0.02mm, symmetry can reach 0.05mm), have compact conformation, easy to assembly, working (machining) efficiency is high, the advantage of good reliability.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present invention is described.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
The specific embodiment
As shown in the figure, the present invention includes support 1 and the gripping sleeve 2 that is fixed on support 1 one ends, gripping sleeve 2 is parts that the present invention and end mill join, has elasticity, and affixed with support 1, when lock-screw 13 lockings, whole device just connects to an integral body with the milling machine spindle shell.An end is by bearing 3 supporting connecting axles 4 on support 1, and connecting axle 4 is given prominence in gripping sleeve 2, and the other end links to each other by transmission mechanism between connecting axle 4 and the output shaft 6 by bearing 5 supporting output shafts 6 on the support 1.Support 1 is a hollow-core construction, and the transmission mechanism between connecting axle 4 and the output shaft 6 is arranged on the hollow part 7 of support 1.Be that support 1 is linked to each other by adjustable docking mechanism with right support body 9 by left socle body 8 and constitutes, output shaft 6 is bearing on the left socle body 8, and connecting axle 4 is bearing on the right support body 9, and the transmission mechanism between connecting axle 4 and the output shaft 6 is the belt pulley transmission.Lean on the spindle nose of the connecting axle 4 of gripping sleeve 2 one ends to be used for linking milling machine spindle, the milling machine spindle rotation is passed to belt pulley with moment of torsion, by three Y type belts moment of torsion is passed to the left end belt pulley again, in the middle of the left end belt pulley below output shaft 6 hole 14 is arranged, after slotting cutter is contained in and locks in the hole 14, moment of torsion just passes on the milling cutter 15, realizes milling effect.Adjustable docking mechanism comprises double thread connecting rod 10, the direction of two screw threads is opposite on the double thread connecting rod 10, the two ends of double thread connecting rod 10 are screwed in respectively on left socle body 8 and the right support body 9, are provided with at left socle body 8 to be provided with long slot bore 12 on attachment screw 11, the right support body 9 and to cooperatively interact and be connected and fixed.Double thread connecting rod 10 is left-handed on one side, on one side for dextrorotation, unclamps attachment screw 11, rotates the adjusting that double thread connecting rod 10 just can be realized support length, thereby realizes the adjusting of belt elasticity.Above-described embodiment only is that the preferred implementation of milling with anchor clamps to machining hole internal keyway of the present invention is described; be not that the design and the scope of inventing limited; under the prerequisite that does not break away from the present invention program; various external form modification and improvement that those skilled in the art make technical scheme of the present invention all should fall into the protection domain with anchor clamps of milling of machining hole internal keyway of the present invention.
