Description
Technical field
The present invention relates to the diesel locomotive field, especially a kind of cross axle clamp for machining.
Background technology
Cross axle is a vital part in the diesel locomotive power transmission shaft assembling universal coupling, the flatness of perpendicularity, symmetry and each axis of cross axle four axle journals requires very high, the balance and the service life of its processing precision direct influence universal coupling transmission.In order to guarantee crudy, must make special-purpose cross axle anchor clamps, existing cross axle process equipment is a horizontal milling machine, anchor clamps are cross keyway calibration locator.Add man-hour, first end face milling, back centering, operation is disperseed, and working (machining) efficiency is low, is difficult to guarantee part processing precision.
Summary of the invention
Disperse in order to overcome existing cross axle anchor clamps operation, working (machining) efficiency is low, and the deficiency of low precision the invention provides a kind of cross axle clamp for machining.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cross axle clamp for machining, comprise support body, hold-down devices, centralized positioning device, go up rotary table plate, axle journal fixture, whole positioner and stationary platen, hold-down devices is connected the support body top, stationary platen is connected the support body bottom, the centralized positioning device is vertically connected on the central authorities of stationary platen, last rotary table plate is enclosed within on the centralized positioning device, with stationary platen embedding mutually, the axle journal fixture is arranged on the rotary table plate, and whole positioner is between last rotary table plate and stationary platen.
The hold-down devices bottom is provided with spring and supports.
The centralized positioning device is a spring spindle that the top is taper.
Be provided with spring housing between last rotary table plate and the stationary platen.
Axle journal fixture central authorities are provided with v-depression, are connected on the rotary table plate by two spring loop bars.
Whole positioner is an end-toothed disc, and its first half is connected the bottom of rotary table plate, and the latter half is connected the top of stationary platen.
The invention has the beneficial effects as follows that these anchor clamps just can be realized the processing of cross axle high accuracy size and datum hole on engine lathe, adopt high-precision end-toothed disc engagement location, improved the location indexing accuracy greatly; The V-type positioner and top in all adopt spring floating formula structure, can effectively solve cross axle thickness and the inconsistent problem of journal size, make the cross axle positioning stablity reliable; Use convenient mounting and clamping, reliable clamping, five equilibrium location be height accurately.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a cutaway view of the present invention;
Fig. 2 is the connection diagram of rotary table plate and axle journal fixture in the present invention.
1. support bodys among the figure, 2. hold-down devices, 3. the centralized positioning device is 4. gone up rotary table plate, 5. axle journal fixture, 51. v-depressions, 6. whole positioner, 7. stationary platen, 8. spring supports, 9. spring housing, 10. spring loop bar.
The specific embodiment
As Fig. 1 is schematic diagram of the present invention, Fig. 2 is the connection diagram of rotary table plate and axle journal fixture in the present invention, a kind of cross axle clamp for machining, comprise support body 1, hold-down devices 2, centralized positioning device 3, last rotary table plate 4, axle journal fixture 5, whole positioner 6 and stationary platen 7, hold-down devices 2 is connected support body 1 top, stationary platen 7 is connected support body 1 bottom, centralized positioning device 3 is vertically connected on the central authorities of stationary platen 7, last rotary table plate 4 is enclosed within on the centralized positioning device 3, with stationary platen 7 embedding mutually, axle journal fixture 5 is arranged on the rotary table plate 4, and whole positioner 6 is between last rotary table plate 4 and stationary platen 7.Hold-down devices 2 bottoms are provided with spring and support 8.Centralized positioning device 3 is the spring spindles that the top is taper.Be provided with spring housing 9 between last rotary table plate 4 and the stationary platen 7.Axle journal fixture 5 central authorities are provided with v-depression 51, are connected on the rotary table plate 4 by two spring loop bars 10.Whole positioner 6 is an end-toothed disc, and its first half is connected the bottom of rotary table plate 4, and the latter half is connected the top of stationary platen 7.
During use, remove the lathe spindle upper chuck earlier, support body 1 is connected with lathe spindle by conical surface location and coupling bolt; Again hold-down devices is upwards unclamped; Then cross axle is contained on the rotary table plate 4, in wherein axle journal was packed the v-depression 51 of axle journal fixture 5 central authorities into, spring loop bar 10 can play the effect of equalizing pressure; Then the centre bore that centralized positioning device 3 is inserted on the cross axis faces is determined the position, spider center, has so just limited the cross axle six-freedom degree, because centralized positioning device 3 is the spring spindles that the top is taper, can improve stability; Put down pressure device 2 then, cross axle is pressed on the rotary table plate 4, spring support 8 can improve the stressed uniformity of cross axle, avoids damaging by pressure; Then utilize whole positioner 6 combined and divided location, determine the cross axle position; Hold-down devices 2 is screwed down again, will goes up rotary table plate 4 and be pressed on the stationary platen 7, at this moment, the first half of whole positioner 6 and Lower Half combination engagement so just can be carried out the processing of cross axle face work and spooling neck centre bore.After machining, unclamp hold-down devices 2, by being installed in the effect of the spring housing 9 between rotary table plate 4 and the stationary platen 7, whole positioner is two parts disengagement about in the of 6, to go up 90 ° of rotary table plate transpositions, hold-down devices 2 will go up rotary table plate 4 again and compress, and can carry out the processing of second axle journal, circulate with this, finish the processing of cross axle four axle journals.
These anchor clamps have solved the key of cross axle processing, promptly guarantee the machining accuracy of four axial end and centre bore benchmark, guarantee the symmetry size of four axle journal end faces to the spider center; Beat the end face centering, guarantee that perpendicularity and four axistyle that four axle journals are mutual are in the same plane; The alignment pin that change resident office uses on clamp structure or the location calibration mode of positioning key structure, and adopt high-precision end-toothed disc engagement location, improved the location indexing accuracy greatly; The location of cross axle on anchor clamps, adopt centralized positioning device 3 and axle journal fixture 5 to determine an axle journal of cross axis faces centre bore and cross axle respectively, whole frees degree of cross axle have been limited, simultaneously, centralized positioning device 3 and axle journal fixture 5 all adopt spring floating formula structure, can effectively regulate cross axle thickness and the inconsistent problem of journal size, make the cross axle positioning stablity reliable; Cross axle clamping once on these anchor clamps can be finished the processing of end face milling and centering, improves working (machining) efficiency.
These anchor clamps can solve the processing of cross axle and the first-class 90 ° of calibration parts of cross pin on the diesel locomotive power transmission shaft assembling universal coupling simultaneously; Guarantee the machining quality of workpiece; Also have excellent popularization and reference function for the jig Design application that needs in the processing to carry out all the other angle workpiece of accurate calibration simultaneously.。
