Detailed description of the invention
With reference to the accompanying drawings embodiment of the present utility model is described in detail.
Fig. 1 is the schematic front view of the milling fixture of the bolt hole end face representing automobile connecting bar of the present utility model.Fig. 2 is the schematic top plan view of the milling fixture of the bolt hole end face representing automobile connecting bar of the present utility model.Fig. 3 is the schematic side view of the milling fixture of the bolt hole end face representing automobile connecting bar of the present utility model.
As shown in Figure 1 to Figure 3, the milling fixture of the bolt hole end face of automobile connecting bar of the present utility model includes bearing 10, apotting spindle 20, Type B replaceable locating pin 30 and locking member 40.Wherein, bearing 10 is made up of base plate 11 and the riser 12 erected on base plate 11.
Apotting spindle 20 can be connected with the riser 12 of bearing 10 to mounting or dismounting, for positioning the major part of automobile connecting bar L, is formed with connection thread spindle 21 on the end face of the positioning end of apotting spindle 20.
Type B replaceable locating pin 30 can be connected with the riser 12 of bearing 10 to mounting or dismounting, positions the microcephaly of automobile connecting bar L.
Locking member 40 includes lock nut 41 and quick change packing ring 42, the internal diameter of the external diameter of lock nut 41 bolt hole less than described automobile connecting bar L, by lock nut 41 being fastened on connection thread spindle 21, the major part of the automobile connecting bar L being enclosed within outward on apotting spindle 20 is fixed between the riser 12 of bearing 10 and quick change packing ring 42.
Specifically, apotting spindle 20 is fixed on the left side of the riser 12 of bearing 10 by nuts and washers, what Type B replaceable locating pin 30 was fixed on the right side of the riser 12 of bearing 10, apotting spindle 20 and Type B replaceable locating pin 30 and riser 12 by nuts and washers coordinates the interference fit being H7/js6.In figure, double dot dash line represents automobile connecting bar L, now, the big end hole of the automobile connecting bar of unprocessed bolt hole end face can be placed on apotting spindle 20, and microcephaly's borehole jack is in Type B replaceable locating pin 30.Quick change packing ring 42 is twisted on apotting spindle 20 by screw thread against the big end hole end face of automobile connecting bar, lock nut 41, is abutted against with quick change packing ring 42 via packing ring.As it is shown in figure 1, the ledge of Type B replaceable locating pin 30 is distributed up and down, can restricting vehicle connecting rod along the rotational freedom of the axis of apotting spindle 20.The face of cylinder of apotting spindle 20 two one-movement-freedom-degrees of restricting vehicle connecting rod and two can swing degree of freedom.The shaft shoulder of apotting spindle 20 can limit an one-movement-freedom-degree.Now automobile connecting bar positions completely, tightens lock nut 41, is clamped by automobile connecting bar L.Now, vertical knife bar and cutterhead can be used to carry out milling.After milling completes, unscrew lock nut 41, one end open due to quick change packing ring 42, it directly can be taken off, the big end hole diameter of automobile connecting bar is more than lock nut 41 and the maximum gauge of packing ring, so automobile connecting bar can directly take off, turns direction, use same method by the clamping of automobile connecting bar location, the bolt hole end face of milling other end.After milling completes, make to be taken off by connecting rod in aforementioned manners, enter next process.
That is, when using such milling fixture, apotting spindle and Type B replaceable locating pin are fixed on the riser of bearing, then will be enclosed within outside the two ends of automobile connecting bar on apotting spindle and Type B replaceable locating pin, finally by lock nut and quick change packing ring, automobile connecting bar is fixed between the riser of bearing and quick change packing ring, it becomes possible to complete automobile connecting bar is fixed.Additionally, when dismantling automobile connecting bar, unclamp lock nut and nut need not be taken off, then taking off quick change packing ring, due to the internal diameter of internal diameter compound lock nut of the bolt hole of automobile connecting bar, if thus taking off automobile connecting bar axially outward and just it can be dismantled along apotting spindle.
Therefore, by so simple structure, it is possible to simply and quickly single automobile connecting rod is carried out clamping, and, can accurately automobile connecting bar be positioned by apotting spindle and Type B replaceable locating pin, it is ensured that machining accuracy.It addition, the simple in construction of milling fixture of the present utility model, it is easy to manufacturing, production cost is low.
It addition, apotting spindle 20 and Type B replaceable locating pin 30 riser 12 with bearing 10 can be connected in the way of being threaded connection, thus the assembly working of milling fixture is simpler, it is possible to assemble milling fixture more rapidly.
Specifically, apotting spindle includes axle main body, is formed in the side of axle main body and connects thread spindle, and the opposite side in axle main body sequentially forms the shaft shoulder, bearing pin and thread spindle.By bearing pin being inserted in the connecting hole of riser, then by coordinating between nut, packing ring and thread spindle, apotting spindle is connected on riser.
It addition, Type B replaceable locating pin also includes axle main body, in axle main body, it is sequentially formed with the shaft shoulder, bearing pin and thread spindle equally.By bearing pin being inserted in the connecting hole of riser, then by nut, coordinating between packing ring and thread spindle, Type B replaceable locating pin is connected on riser.
Certainly, apotting spindle and Type B replaceable locating pin are not limited to threaded with the riser connected mode of bearing, them can be made to connect by other dismountable mode.Such as, the end face at riser is formed and connects pin insertion hole, and the end face at riser inserts connecting pin in the bearing pin of apotting spindle and Type B replaceable locating pin and is attached.
Furthermore it is possible to the lower surface connection at the base plate 11 of bearing 10 has positioning key 13, by positioning key, milling fixture is positioned on milling machine, thus the whole location work of milling fixture is easier, it is simple to quickly carry out milling.It addition, positioning key can be connected with the base plate of bearing by screw.
It addition, each embodiment above-mentioned is only a kind of embodiment, each embodiment above-mentioned combination in any can form various possible connection, and this combination is also contained in protection domain of the present utility model.
Above the milling fixture of the bolt hole end face of the automobile connecting bar of preferred implementation of the present utility model is illustrated, but, this utility model is not limited to above-mentioned specific embodiment, without departing from the scope of claim, can carry out various deformation or change.Various deformation that this utility model is included within the scope of the claims and change.
