Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment being obtained, broadly falls into the scope of this utility model protection.

Referring to a kind of crankshaft drilling journal hole fixture shown in Fig. 1 to Fig. 4, including base plate 6, described base plate 6 is provided with peace Dress plate 3, described installing plate 3 is provided with the first V-type seat 13 of positioning crankshaft two end curved bar 8 being parallel to each other and the second V-type seat 9, insertion between described first V-type seat 13 and the second V-type seat 9 is provided with into tool bore 1, described first V-type seat 13 and the second V-type seat It is provided with the crank throw seat 12 of the crank throw of positioning bent axle between 9, described crank throw seat 12 offers an arcuate groove, described installing plate 3 back sides are additionally provided with a compression cylinder 5, and the cylinder rod of described compression cylinder 5 passes through installing plate 3, and this installing plate 5 bar end is hinged It is connected with a depression bar 11, described installing plate 3 is additionally provided with a hinged seat, described hinged seat includes ball stud 2, described bulb Jaw 14 is hingedly connected with bolt 2, is hinged in the middle part of described jaw 14 end and described depression bar 11.

Process is as follows when in use for this utility model, is first arranged on lathe this fixture by base plate 6, by crank Curved bar 8 two ends be placed on the first V-type seat 13 and the second V-type seat 9, now the crank throw of crank naturally falls in crank throw seat On 12 arcuate groove, then start cylinder 5, cylinder rod 15 bar of cylinder 5 moves forward, in ball stud 2 and installing plate 5 bar Under collective effect, depression bar 11 can be pressed on crank throw face so that whole bent axle is fixed on fixture, then restarts on lathe Drilling tool, drilling tool carries out drilling operation to the axle journal 17 of bent axle, and (axle journal 17 on the downside of crank throw needs and the second V-block offsets Connect), after the completion of boring, bent axle is taken off.

Further, described base plate 6 is provided with least one column 7, described column 7 apical grafting is on the second V-type seat 9. Because, when carrying out drilling operation, fixture and bent axle all can carry out stress in vertical direction, in order to increase the work of this fixture When stability, at least one column 7 is provided with base plate 6 so as to apical grafting is on the second V-type seat 9.

Further, described second V-type seat 9 is being further fixedly arranged on cushion block 10 near that side of crank throw seat 12.To not When the bent axle of same model is processed, the length of bent axle is different, so arranging cushion block 10 on the second V-type seat 9, can make The axle journal 17 obtaining the bent axle of different model all can abut against with cushion block 10 it is ensured that this fixture can adapt to the song of Multiple Type Axle.

Further, described column 7 is two, is threaded on base plate 6.During in order to further enhance the work of this fixture Stability, two columns 7 are being provided with base plate 6, meanwhile, are being additionally provided with reinforcement 4 between base plate 6 and installing plate 3, Further increase the intensity of whole fixture.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this Within the spirit of utility model and principle, any modification, equivalent substitution and improvement made etc., should be included in this utility model Protection domain within.
