Bar, the corresponding guide rod in the left side of each sliding slot, each guide rod both pass through the sliding block of corresponding position and are slidably connected often with the sliding block
The pressure spring covered on guide rod is equipped between a sliding block and guide rod seat, the grip block is wedge block and deviates from fixing axle axis
Face inclined surface, grip block is larger close to the smaller separate mounting base end in mounting base end, is cased with shift(ing) ring outside grip block described in four,
The shift(ing) ring is equipped with the through-hole of truncated rectangular pyramids shape, and each grip block corresponds to a medial surface of through-hole, the medial surface of through-hole
Gradient is consistent with the gradient of the inclined surface of corresponding grip block, at least one liquid is equipped between the shift(ing) ring and mounting base
The hydraulic stem of cylinder pressure, hydraulic cylinder is fixedly connected with shift(ing) ring, and the bottom of hydraulic cylinder is fixedly connected with mounting base, hydraulic cylinder it is hydraulic
Cylinder is parallel with fixing axle.
Preferably, the medial surface of grip block is equipped with arc groove.
The utility model, structure is simple, mount and dismount workpiece to be added it is very convenient quickly, save manufacturing procedure, improve
Produce and process efficiency；Clamping to machined part is accurate, ensure that processing quality.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model Fig. 1 right side view；
Fig. 3 is the schematic diagram that the utility model clamps cylinder body.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
It is provided by Fig. 1 to Fig. 3, a kind of centre frame oild chuck, including mounting base 1, the side of mounting base 1 is equipped with fixing axle
2, which is characterized in that the mounting base is circumferentially laid with four sliding slots away from the axis of a lateral edge fixing axle 2 of fixing axle 2
3, sliding slot 3 is arranged radially along fixing axle 2, and mounting base 1 is fixed with guide rod seat 4 away from a middle side part of fixing axle 2, described in four
Sliding block 5 is slidably connected in sliding slot 3, the sliding block 5 is respectively and fixedly provided with grip block 6, the guide rod seat 4 away from the side of mounting base 1
On it is circumferential uniformly distributed fixed there are four guide rod 7 along fixing axle 2, the corresponding guide rod 7 in the left side of each sliding slot 3, each guide rod 7 is worn
It crosses the sliding block 5 of corresponding position and is slidably connected between each sliding block 5 and guide rod seat 4 with the sliding block 5 and be equipped with the pressure covered on guide rod 7
Spring 8, the grip block 6 are wedge block and the face inclined surface for deviating from 2 axis of fixing axle, and grip block 6 is smaller close to 1 end of mounting base
It is larger far from 1 end of mounting base, shift(ing) ring 9 is cased with outside grip block 6 described in four, the shift(ing) ring 9 is equipped with the logical of truncated rectangular pyramids shape
Hole, each grip block 6 correspond to a medial surface of through-hole, and the gradient of the medial surface of through-hole is inclined with corresponding grip block 6
The gradient on inclined-plane is consistent, between the shift(ing) ring 9 and mounting base 1 be equipped at least one hydraulic cylinder 10, hydraulic cylinder 10 it is hydraulic
