Utility model content
It is a kind of for processing the fixture of three-way connection that the utility model provides, and when improvements are to convert the other end of working joint at every turn, just need not proofread and correct directly feed turning, improved efficiency, made up the deficiencies in the prior art.
The purpose of this utility model is achieved through the following technical solutions:
For processing a fixture for three-way connection, comprise support, index table, positioner, hold down gag four parts.
Support is one, and with the bent plate structure of the axis of cone, the axis of cone and lathe main axis hole are connected, and the horizontal plane of bent plate structure, as design basis plane, is connected with index table above.
Index table is designed with two orthogonal V-shaped grooves,, the long V-shaped groove vertical with main shaft, a short V-shaped groove parallel with main shaft, long V-shaped groove can limit 4 frees degree of workpiece, 2 frees degree of short V-shaped groove restriction workpiece, thereby 6 frees degree that guarantee workpiece are limited, and obtain only definite position.The Main Function of index table is supporting workpiece, the 2nd, and accurate calibration.Index table upper end is designed with screwed hole, and lower end is designed with locating hole B and the little axis of cone, and on the little axis of cone and support, conical bore is connected.
It is to locate with Position with One Plane and Two Holes that index table is connected on support, Position with One Plane and Two Holes location utilizes large plane to eliminate three degree of freedom, two frees degree of index table bottom column part restriction, the free degree that another short cylindrical pin restriction is rotated around cylindrical portion, thus realize location completely.
Positioner is comprised of nut C, alignment pin, stifled platform, spring, and the locating hole A on alignment pin and support is connected.Positioner is connected in support and index table, mainly plays location index table.During work after 90 ° or 180 ° of the V-arrangement index tables of one end rotational support workpiece that process joint, the cone end of positioner alignment pin will be due to the thrust of spring, insert in the locating hole B of index table, guarantee the accurate calibration of workpiece location, thus feed turning.
Hold down gag is comprised of parallels, nut A, screw rod and pressing plate, and screw rod is connected with the screwed hole on index table, mainly plays workpiece pressing.
As of the present utility model preferred, the axis of cone on support is designed to Morse's taper No. 6, conveniently coordinates with lathe main axis hole, can play self-locking action.
As of the present utility model preferred, index table upper end is designed with the screwed hole of M10, and lower end is designed with locating hole B and the little axis of cone, and on the little axis of cone and support, conical bore is connected, and locating hole B and positioner are connected.
Compared with prior art, the beneficial effects of the utility model are, while converting the other end of working joint, by index table, to locate at every turn, without secondary clamping, just need not proofread and correct directly feed turning, labor strength is little, time saving and energy saving, has greatly improved production efficiency.
