Description
Technical field
The invention belongs to field of fixtures, be specifically related to a kind of milling major axis keyway fixture.
Background technology
Milling is a kind of high efficiency machining process, and Milling Process is that the multiple-cutting-edge tool by rotating carrys out cutting workpiece, and add man-hour, cutter usually also will do feed motion while rotating, to complete the processing of the longer workpiece of length.
In factory; usually can use with the major axis of two keyways, to realize the miscellaneous part rotation that major axis rotarily drives two keys connections; and due to higher to the requirement of running accuracy; usually all require that two keyways lay respectively at the two ends of the same diameter of major axis, this just makes difficulty when processing major axis increase.When the Milling Process of major axis keyway, usually fixture can be used, existing milling major axis keyway fixture generally includes two jaws, described two jaws clamp the two ends of major axis respectively, by the rotary motion of milling cutter and feed motion, keyway processing is carried out to major axis again, after processing a keyway, rotate major axis gradually, and measure its anglec of rotation with protractor, stop operating when making the major axis anglec of rotation be 180 degree, with jaw, major axis is clamped again, carry out the processing of the second keyway, owing to all needing the anglec of rotation with protractor amount major axis when processing the second keyway of each root major axis, to ensure that the first keyway and the second keyway are positioned at the two ends of the same diameter of major axis, make working (machining) efficiency low, and when being difficult to ensure that major axis maintains static with in the process of jaw clamping major axis after major axis has rotated 180 degree of stoppings, major axis can be subjected to displacement unavoidably, thus the location of causing major axis last is inaccurate, and then cause the relative position inaccuracy of the first keyway and the second keyway.In addition, because long axis length is longer, and the stroke of milling cutter is limited, and when milling cutter processes the keyway of major axis one, usually need to carry out secondary clamping and could carry out continuation processing to the other end of major axis, troublesome poeration, working (machining) efficiency are low.
Summary of the invention
The technical problem to be solved in the present invention is the technological deficiency low for existing milling major axis keyway fixture working (machining) efficiency, machining accuracy is low, provides the milling major axis keyway fixture that a kind of working (machining) efficiency is high, machining accuracy is high.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: milling major axis keyway fixture, comprise milling stations and clamping sleeve, described milling stations upper end is provided with groove, and the longitudinal center line of described groove is provided with one group of backstay, and described backstay comprises slide bar and threaded rod, described threaded rod is threadedly connected to bottom portion of groove, described slide bar is fixedly connected on center, threaded rod top, and the upper end of slide bar is positioned at the first keyway of major axis, and the bottom of slide bar and major axis first keyway offsets; The cross section of described clamping sleeve is the circular of breach, and clamping sleeve and groove fasten, and the longitudinal center line on clamping sleeve top is provided with tapped through hole, and be provided with one group of trip bolt in tapped through hole, described trip bolt and major axis offset.
Adopt the milling major axis keyway fixture of technical solution of the present invention, comprise milling stations and clamping sleeve, described milling stations upper end is provided with groove, groove for installing backstay thus a part for major axis self can being made to sink in groove, state major axis being in more balance, the longitudinal center line of groove is provided with one group of backstay, backstay is for supporting bottom major axis, backstay is positioned on the longitudinal center line of groove, thus when adjust the position of milling cutter and top place milling cutter being fixed on major axis can ensure that the keyway processed and the first keyway are positioned on the two ends of the same diameter of major axis, and ensure that the position of milling cutter maintains static, the major axis of tree root equivalent signals can be processed exactly, backstay comprises slide bar and threaded rod, the upper end of slide bar is positioned at the first keyway, thus support major axis and locate to major axis, threaded rod is threadedly connected to bottom portion of groove, thus threaded rod can move up and down relative to bottom portion of groove, and then threaded rod can be with moving slide-bar to move up and down, therefore according to the height of the major axis adjustable backstay of different model, the cross section of clamping sleeve is the circular of breach, thus the convenient cross section that holds is circular major axis, and the end of clamping sleeve can fit better with milling stations, be connected, the longitudinal center line on clamping sleeve top is provided with tapped through hole, and tapped through hole is for installing trip bolt, and trip bolt offsets with major axis thus trip bolt coordinates together with backstay and major axis can be located.
Know-why of the present invention and technique effect are: because slide bar is straight up, slide bar upper end is positioned at the first keyway of major axis, and the bottom of the top of slide bar and the first keyway offsets, therefore the first keyway is positioned at the bottom end of the vertical diameter of major axis, and tapped through hole is positioned on the longitudinal center line on clamping sleeve top, namely trip bolt is positioned on the longitudinal center line on clamping sleeve top, because clamping sleeve is the circular of breach, the two ends of clamping sleeve are connected with the milling stations of level, therefore the top axial of clamping sleeve is centrally located at above major axis top, so the top of trip bolt and major axis offsets, and trip bolt is positioned at the top end of the vertical diameter of major axis, thus major axis stress balance can be ensured, and then major axis is compressed location, and be positioned at major axis bottom due to the first keyway, therefore only milling cutter need be adjusted to the top end of major axis and maintain static, just can process exactly major axis, machining accuracy is high, and keep the invariant position of milling cutter, different major axis can be changed and to its accurate machining, avoid an often processing major axis all to need to carry out accurate Set and Positioning to major axis, improve working (machining) efficiency.In addition, slide bar can slide in existing chute, therefore slidably major axis replaces the feed motion of milling cutter, avoids because milling cutter stroke is limited that some position of major axis that is that cause cannot process, therefore need secondary clamping just can complete the processing of major axis, simple to operate, improve working (machining) efficiency.
Further, described clamping sleeve and milling stations removably connect.Thus major axis can be placed on backstay by direct after clamping sleeve dismounting when major axis is installed, avoid and major axis slip cannot be inserted in clamping sleeve because of limited space.
Further, described clamping sleeve two ends are provided with latch segment, are provided with clamping screw between described latch segment and milling stations.Thus clamping sleeve is fixed on milling stations surface, and turn the dismounting that clamping screw can realize clamping sleeve.
Further, described latch segment is provided with bracelet.Due to the laminating that the laminating between latch segment and milling stations is between plane and plane, not easily two planes are separated with hand during dismounting, and can directly clamping sleeve upwards be mentioned by bracelet, reduce the dismounting difficulty of clamping sleeve and milling stations.
Further, described backstay has two, and described tapped through hole has two.Tapped through hole have two namely trip bolt have two, 2 determine straight lines, and therefore two backstays and two trip bolts can ensure the steady location of major axis.
