Abstract
The utility model relates to a milling clamp for machining a key slot in a hole. The clamp comprises a bracket and a clamping sleeve fixed at one end of the bracket, wherein one end of the bracket bears a connecting shaft through a bearing, the connecting shaft protrudes out in the clamping sleeve, the other end of the bracket bears an output shaft through the bearing, the connecting shaft is connected with the output shaft through a transmission mechanism, the bracket is a hollow structure, and the transmission mechanism between the connecting shaft and the output shaft is arranged at the hollow part of the bracket. The utility model overcomes the defect that an ordinary vertical milling machine cannot machine the key slot in the hole in the prior art; through the design, the milling clamp can be used for machining key slots in different holes after being combined with the vertical milling machine, thereby not only reducing the machining cost and well ensuring the dimension and symmetrical degree of the key slot (the width of a slot can reach 0.02mm, and the symmetrical degree of the slot can reach 0.05mm); moreover, the utility model has the advantages that the milling clamp has a compact structure, is convenient to assemble and has high machining efficiency and strong reliability.
Description
Technical field
The utility model relates to milling of a kind of machining hole internal keyway and uses 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 utility model provides milling of a kind of machining hole internal keyway to 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 scheme that its technical problem that solves the utility model adopts 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 utility model 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 utility model is described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
The specific embodiment
As shown in the figure, the utility model comprises support 1 and is fixed on the gripping sleeve 2 of support 1 one ends that gripping sleeve 2 is parts that the utility model 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 the utility model machining hole internal keyway is described; be not that design and scope to utility model limits; under the prerequisite that does not break away from the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model all should fall into the protection domain with anchor clamps of milling of the utility model machining hole internal keyway.
