Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of fixed structure of automobile engine crankshaft, including pedestal 1 and only axis 5, pedestal 1 are circular cylinder
Shape structure, the inner wall of pedestal 1 offer an only slot 6, and only axis 5 is slidably connected through the side wall of pedestal 1 with only slot 6, only 5, axis
Sidewall weld in only 6 one section of inside of slot has baffle 7, and baffle 7 and the bottom of only slot 6 are welded with the first spring 8, pedestal 1 jointly
Interior bottom rotating plate 2 is rotatably connected to by bearing, rotating plate 2 circumferentially equidistantly offers multiple only holes 4, and rotating plate 2 is the bottom of far from
One end of seat 1 is opened up there are four location hole 3, and the equal gluing of side wall of each location hole 3 has rubber weather strip, and location hole 3 is interior
Diameter is matched with crankshaft diameter, realizes positioning and limit to crankshaft, and rotating plate 2 is welded with shaft 9, shaft 9 far from one end of pedestal 1
One end far from rotating plate 2 is welded with briquetting 10；
Briquetting 10 offers indent 17 far from one end of shaft 9, and the side wall sealing of indent 17 slidably connects sliding block 18, sliding
Block 18 is welded with electric pushrod 19 far from one end of shaft 9, and the side wall of indent 17 offers multiple sliding slots 14, each sliding slot 14
Inner wall, which seals, slidably connects a piston 13, and each side of the piston 13 far from indent 14 is welded with connecting rod 11, and every two
A connecting rod 11 is welded with a clamping plate 15 far from one end of respective connected piston 13 jointly, briquetting 10 close to shaft 9 one
End is welded with multiple locating pieces 16.
Only axis 5 can be inserted into each in only hole 4 and offset with rotating plate 2；Each locating piece 16 is hollow cylindrical structure, often
A locating piece 16 corresponds to two connecting rods 11；Each connecting rod 11 is through the side wall for being slidably connected at corresponding locating piece 16；Each
Clamping plate 15 is annular plate-like structure, and each clamping plate 15 is respectively positioned in corresponding locating piece 16；The bottom of indent 17 and cunning
Hydraulic oil is full of between block 18；The electric putter of model DTZ60 can be selected in electric pushrod 19.
When needing machining crankshafts, needing to fix on crankshaft, one end of crankshaft connects flywheel, and the other end connects belt pulley,
So that the diameter of axle of crankshaft two end is in different size, it is not easy to uniformly clamp, one end that crankshaft connects flywheel can be put into location hole 3
In, since the side wall gluing of location hole 3 has rubber strip, and the aperture of location hole 3 is matched with crankshaft diameter, is determined so that crankshaft is put into
Certain pre-determined bit may be implemented behind hole 3 in position, and location hole 3 can limit crankshaft movement in the horizontal direction, while by crankshaft
