Description

A kind of turnery processing motor casing hydraulic pressure automatic fixture
Technical field
The present invention relates to a kind of Digit Control Machine Tool fixture for processing, specifically a kind of turnery processing motor casing is pressed from both sides automatically with hydraulic pressure Tool.
Background technology
Motor casing is as bearing and the installing component of rotor in whole motor, and the stable rotation for motor serves pass The effect of key.The significant properties of motor casing processing is processing content based on turning.Fig. 1-3 is the structure of common motor casing In schematic diagram, Fig. 1-3, a1 holes and a2 holes are traditional Set and Positioning hole(A1 holes are opened on boss d), b1 faces, b2 faces and b3 faces For traditional clamping seal face, c1 faces, c2 faces and c3 faces are traditional Set and Positioning face.Using conventional brace clamping fixing motor housing, When motor casing is processed, corresponding Set and Positioning hole, clamping seal face and Set and Positioning face as shown in Fig. 1-3 are used as Set and Positioning Point, plane and two pitses positioning, manually operated fixture and clamping motor shell, turning A holes, B faces, C holes, D faces, E faces are carried out to motor casing With F holes, wherein B faces and C holes constitutes bearing chamber.For the bearing chamber of motor casing dimensional tolerance, roughness and cylindricity have compared with High processing request, it is desirable to which the dimensional tolerance grade of bearing chamber is H7, roughness is Ra0.8, and the cylindricity in C holes is 0.005mm. Using conventional brace clamping fixing motor housing, with certain deficiency:First, Set and Positioning point apart from the position of bearing chamber compared with Far, clamping is rigidly poor, and part can produce slight deformation in turning process, causes 0.005mm cylindricity to be difficult to ensure that, Often there is overproof situation, therefore the turning amount of feeding need to be suitably reduced during turning, to ensure cylindricity requirement;Second, due to Set and Positioning point is too outer, causes the rotating diameter of fixture larger, therefore the speed of mainshaft need to be reduced in turning, but this can influence to add Work efficiency rate;3rd, tradition, which is clamped, needs hand-operated clamping, and the manually control for clamping force size is not sufficiently stable, and is easily caused part dress Folder deformation, while clamping efficiency is low;4th, the dynamic balance performance of manual is poor, and fixture is also easy to produce in rotary course Vibration, influences part processing precision.
