Description

Crankcase Milling Machining fixture
Technical field
The utility model relates to crankcase Milling Machining clamping technique, is related specifically to a kind of crankcase Milling Machining fixture.
Background technology
Crankcase is generally aluminum alloy die casting, and its shape is comparatively complicated, various hole and face more, and position and size dimension require strict.Because it is complex-shaped, therefore, when carrying out Milling Machining to it, clamping is more difficult.Prior art crankcase Milling Machining clamp method, adopts pressing plate to be fixed on milling machine table face, because Milling Machining face can not arrange pressing plate, pressing plate can only be arranged on edge or edge.So-called pressing plate clamping refers to and adopts middle part to have bolt to connect the steel plate with work top, and one end of steel plate is provided with parallels, and the other end is pressed in by holding parts edge, by screwing bolts by mode fixing for part.This method of clamping not only efficiency is lower, and the position of each clamping is not fixed, and needs tool setting again during Milling Machining.Obviously, it is lower that prior art crankcase Milling Machining clamp method also exists clamping efficiency, and the position of each clamping is not fixed, and needs the problems such as tool setting again.
Summary of the invention
In order to solve prior art crankcase Milling Machining clamp method, to there is clamping efficiency lower, and the position of each clamping is not fixed, and needs the problems such as tool setting again, the utility model proposes a kind of crankcase Milling Machining fixture.The utility model crankcase Milling Machining fixture, comprise base plate, transverse holes locating dowel, transverse plane locating piece and pneumatic pressure head, transverse holes locating dowel is arranged on the transverse holes that its position, base plate middle and upper part and size and crankcase upper surface carry and matches, and the transverse holes carried in crankcase upper surface is sleeved on after in this transverse holes locating dowel, the bottom surface of crankcase is just fitted on base plate; Transverse plane locating piece is arranged on base plate middle and lower part, and its position size matches with the boss of clamping crankcase lower surface respectively, and is sleeved on after in transverse holes locating dowel in crankcase transverse holes and is just stuck in boss side surfaces; Two pneumatic pressure head are symmetricly set on the longitudinal both sides of crankcase, and after its cylinder is opened, crankcase is just pressed on base plate by pressure head.
Further, the utility model crankcase Milling Machining fixture, described pneumatic pressure head is level type, comprises pillar, pressure head and cylinder; Pillar is fixed on base plate, and the middle part of pressure head is hinged on pillar upper end; Cylinder is arranged on rear side of pillar, and follower head and the cylinder axis of pressure head are hinged.
The Advantageous Effects of the utility model crankcase Milling Machining fixture is the position that can at every turn clamp is fixed position, and do not need tool setting again during Milling Machining, and efficiency is higher, easy and simple to handle, structure is simple.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic three dimensional views of crankcase;
Accompanying drawing 2 is the schematic diagram before the utility model crankcase Milling Machining fixture does not clamp crankcase;
Accompanying drawing 3 is the schematic diagram after the utility model crankcase Milling Machining holder crankcase.
Below in conjunction with the drawings and specific embodiments, the utility model crankcase Milling Machining fixture is further described.
Detailed description of the invention
Accompanying drawing 1 is the schematic three dimensional views of crankcase, and in figure, A is transverse holes, and B is boss.As seen from the figure, crankcase is generally aluminum alloy die casting, and its shape is comparatively complicated, various hole and face more, and position and size dimension require strict.Because it is complex-shaped, therefore, when carrying out Milling Machining to it, clamping is more difficult.Prior art crankcase Milling Machining clamp method, adopts pressing plate to be fixed on milling machine table face, because Milling Machining face can not arrange pressing plate, pressing plate can only be arranged on edge or edge.So-called pressing plate clamping refers to and adopts middle part to have bolt to connect the steel plate with work top, and one end of steel plate is provided with parallels, and the other end is pressed in by holding parts edge, by screwing bolts by mode fixing for part.This method of clamping not only efficiency is lower, and the position of each clamping is not fixed, and needs tool setting again during Milling Machining.Obviously, it is lower that prior art crankcase Milling Machining clamp method also exists clamping efficiency, and the position of each clamping is not fixed, and needs the problems such as tool setting again.
Accompanying drawing 2 is the schematic diagram before the utility model crankcase Milling Machining fixture does not clamp crankcase, accompanying drawing 3 is the schematic diagram after the utility model crankcase Milling Machining holder crankcase, and in figure, 1 is base plate, 2 is transverse holes locating dowel, 3 is transverse plane locating piece, and 4 is pneumatic pressure head, and 41 is pillar, 42 is pressure head, 43 is cylinder, and A is transverse holes, and B is boss.As seen from the figure, the utility model crankcase Milling Machining fixture, comprise base plate 1, transverse holes locating dowel 2, transverse plane locating piece 3 and pneumatic pressure head 4, transverse holes locating dowel 2 is arranged on the transverse holes A that its position, base plate 1 middle and upper part and size and crankcase upper surface carry and matches, and the transverse holes A carried in crankcase upper surface is sleeved on after in this transverse holes locating dowel 2, the bottom surface of crankcase is just fitted on base plate 1; Transverse plane locating piece 3 is arranged on base plate 1 middle and lower part, and its position size matches with the boss B of clamping crankcase lower surface respectively, and is sleeved on after in transverse holes locating dowel 2 at crankcase transverse holes A and is just stuck in boss B side; Two pneumatic pressure head 4 are symmetricly set on the longitudinal both sides of crankcase, and after its cylinder is opened, crankcase is just pressed on base plate 1 by pressure head 41.As embodiment, the utility model crankcase Milling Machining fixture, described pneumatic pressure head 4 is level type, comprises pillar 41, pressure head 42 and cylinder 43; Pillar 41 is fixed on base plate 1, and the middle part of pressure head 42 is hinged on pillar 41 upper end; Cylinder 43 is arranged on rear side of pillar 41, and follower head and the cylinder axis of pressure head 42 are hinged.When adopting the utility model crankcase Milling Machining fixture machining crankshafts casing, in the transverse holes suit transverse holes locating dowel that crankcase upper surface is carried, now, should just in time fit with base plate in crankcase bottom surface, and, transverse plane locating piece is also just stuck in the boss side surfaces of crankcase lower surface, completes location, position thus.Open pneumatic pressure head, cylinder piston moves upward, and promotes pressure head and moves downward, be fixed on base plate by crankcase.
Obviously, the Advantageous Effects of the utility model crankcase Milling Machining fixture is the position that can at every turn clamp is fixed position, and do not need tool setting again during Milling Machining, and efficiency is higher, easy and simple to handle, structure is simple.
