Description
Technical field
The utility model relates to a kind of Machining Technology field, is used for the anchor clamps of clamping pipe fitting on specifically a kind of milling machine.
Background technology
When milling machine processing pipe fitting workpiece, generally be to use cushion block, top to use pressing plate and bolt in the workpiece bottom, workpiece is fixed on the workbench, but, is not easy clamping because of the particularity of the workpiece shape of pipe fitting, particularly for the clamping of bend pipe, it is firm to be not easy accurate location and clamping, and workpiece is loosening easily in process, or produces offset deviation, thereby influenced the machining accuracy of workpiece, even caused milling cutter to break or the workpiece damage.
Summary of the invention
In order to overcome above-mentioned defective, it is a kind of rational in infrastructure, easy to operate that the utility model provides, and clamping is firm, can make the pipe fitting self-centering, and the pipe fitting anchor clamps of the milling machine of accurate positioning.
A kind of pipe fitting anchor clamps of milling machine, comprise pressing plate, bolt and cushion block, also comprise chuck body, locating piece and spring, described cushion block is arranged on the chuck body, this cushion block middle part has the hole, the diameter in hole is corresponding with the internal diameter of processed pipe fitting, in this hole, be provided with locating piece, the top of described locating piece is taper and the hole that can stretch out cushion block, tapered lower portion is provided with columned boss, the diameter in the hole on the diameter of this boss and the described cushion block is corresponding, on chuck body, the bottom of locating piece is provided with the hole that is used for mounting spring, is provided with spring in the hole and is connected with locating piece.
Because the utility model is provided with the locating piece of taper in the inner diameter hole of cushion block and processed pipe fitting, under spring action, tapering part peaks in the endoporus of processed pipe fitting, the locating piece of taper can make processed pipe fitting energy self-centering, accurate positioning when clamping, and processed pipe fitting and locating piece contact area are big, and clamping is firm; In the locating piece bottom spring is set, when the pipe fitting of clamping different inner diameters size, processed pipe fitting can be closely cut with locating piece cooperate, increase the fastness of pipe fitting clamping.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, mainly comprise chuck body 4, cushion block 3, pressing plate 1, locating piece 5 and spring 6, described chuck body 4 is a platform-like, and chuck body 4 is detachable the connection with workbench.Described cushion block 3 is arranged on the chuck body 4, and these cushion block 3 middle parts have the hole, and the diameter in hole is corresponding with the internal diameter of processed pipe fitting, and general aperture is slightly larger than processed pipe fitting internal diameter 2 to 6mm.In this hole, be provided with locating piece 5, the top of described locating piece 5 is taper, this tapering part stretches out the hole of cushion block 3, the tube wall of processed pipe fitting just tightly is enclosed within described tapering part outside, the bottom of tapering part is provided with columned boss, and the diameter in the hole on the external diameter of this boss and the described cushion block 3 is corresponding and be arranged in this hole.On chuck body 4, the bottom of locating piece 5 is provided with the hole that is used for mounting spring 6, be provided with spring 6 in the hole and be connected with locating piece 5.
During use, cushion block 3 is installed on the chuck body 4, locating piece 5 is arranged in the hole of cushion block 3, the tapering part on locating piece 5 tops stretches out cushion block 3, processed pipe fitting places the top of cushion block 3, its tube wall is placed in the outside of locating piece 5 tapering parts, and under the effect of spring, locating piece 5 presses closer the bottom at processed pipe fitting.The locating piece 5 of taper can make processed pipe fitting can self-centering when clamping, accurate positioning, and processed pipe fitting and locating piece 5 contacts area are big, clamping is firm.The bottom of locating piece 5 also is provided with spring 6, under the effect of spring 6, locating piece 5 upper taper parts is closely cooperated all the time with processed pipe fitting, increases the fastness of anchor clamps clamping.Processed pipe fitting top makes it fixedly connected with chuck body 4 by pressing plate 1 and bolt 2, and chuck body 4 is connected with the workbench of milling machine by bolt.When the internal diameter size error of processed pipe fitting was big in a collection of, because the utility model locating piece 5 tops are pyramidal structure, the bottom was compressed by spring 6 again, and is so locating piece 5 can support and the fixing pipe fitting of different size, applied widely.Processed pipe fitting in the present embodiment is a bend pipe, at the neck of the other end of bend pipe clamping end supporting seat can also be set, and plays the support fixation effect, makes pipe fitting vibrations or distortion can not occur in process, guarantees crudy.
Because as seen, the utlity model has rational in infrastructurely, easy to operate, clamping is firm, can make the pipe fitting self-centering, and the characteristics such as accurate positioning.
