Abstract
A clamping device for a swinging push broach overcomes the defects of complex processing method, low speed, high cost and difficult guarantee of part quality in the prior art. The utility model is characterized in that the knife handle 7 and the cavity knife body 6 are integrated. Two radial bearings are respectively arranged on two sides of the middle thrust bearing on the shaft 4 in the cavity cutter body 6. The side surface of the boss 2 is in bolt connection with a deflector rod 3 and is connected with the cutter body 6. A cutter head 1 with an inclined surface is inserted into a blind hole on a shaft 4 through a boss 2, and the cutter head 1 is fixed by a driving lever 3. Small volume, simple operation and high efficiency. The cutter head can be used for clamping corresponding cutter heads when equilateral, unequal, through hole, blind hole and polygonal prism-shaped workpieces are machined on various machine tools.
Description
The utility model relates to a kind of machining tool clamping device, particularly a kind of swing push broach clamping device.
When the polygon hole of processing many kinds, small lot, adopt usually in the prior art insert, mechanical stamping or manual punching press, polygon prism then adopts and draws Fig. 2 and mill.The weak point of these processing methods is cumbersome, processed complex, and speed is slow, and cost height, part quality are difficult to guarantee sometimes.
The purpose of this utility model is to solve above-mentioned weak point of the prior art, and a kind of swing push broach clamping device is provided.
Technical solution of the present utility model is: handle of a knife 7 is one with cavity cutter hub 6.The both sides of the middle thrust bearing on the axle 4 in cavity cutter hub 6 respectively are provided with a radial bearing.A be spirally connected driving lever 3 and be connected of the side of boss 2 with cutter hub 6.The cutter head 1 that one inclined-plane arranged on it is in boss 2 inserts in blind hole on the axle 4, cutter head 1 is fixing by driving lever 3, preventing in deep hole processing or during than the workpiece of soft material, the vibrations that cutter head 1 produces relative rotation with workpiece and produced when beginning to cut prevent that cutter head 1 from damaging and guaranteeing the crudy of workpiece.
The advantage that the utility model had is: simple and reasonable for structure, volume is little, and is easy and simple to handle, high efficiency.Change different cutter heads 1 and can process different special shape hole and prism, be specially adapted to the part processing of many kinds, small lot.Handle of a knife 7 has the tapering of standard, can use on various lathes easily.Also but the needs of root user are made required shape.
The drawing of accompanying drawing is described as follows:
Fig. 1 looks schematic diagram for overall structure master of the present utility model.
Fig. 2 is that cutter head 1 and axle 4, the position between the axis 9 concern schematic diagram.
Fig. 3 is the movement locus schematic diagram of point 8 on Fig. 2.
Fig. 4 is that K among Fig. 2 is to view.
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment: handle of a knife 7 is one with cavity cutter hub 6.The both sides of the middle thrust bearing on the axle 4 in cavity cutter hub 6 respectively are provided with a radial bearing.A be spirally connected driving lever 3 and be connected of the side of boss 2 with cutter hub 6.The cutter head 1 that one inclined-plane arranged on it is in boss 2 inserts in blind hole on the axle 4, cutter head 1 is fixing by driving lever 3, preventing in deep hole processing or during than the workpiece of soft material, the vibrations that cutter head 1 produces relative rotation with workpiece and produced when beginning to cut prevent that cutter head 1 from damaging and guaranteeing the crudy of workpiece.The utility model adopts the principle (as Fig. 2) of swing broaching.The cutting edge periphery of cutter head 1 is peripheral identical with the desire Forming Workpiece, between the axis 04 of cutter head 1 and the axis 09 of cutter hub 6 a little angle is arranged.When cutter during along axis 09 feed, cutter head 1 does not rotate with respect to workpiece, but transports movingly once with respect to cutter hub 6, and promptly axis 04 is around axis 09 rotation of tilting, cause cutting edge along circle swing, and then cut and identical polygon hole or the polygon prism of cutting edge periphery.The cutter head of clamping correspondence is used in the time of can be for equilateral, the inequilateral of processing, through hole, blind hole and polygon prismatic workpiece.
