According to the clamp, through the rotation of the spiral grooves, the clamping jaws which are evenly distributed can be gathered toward the center at the same speed, clamp force in various directions is uniform, and the clamp is applicable to the clamping machining of round workpieces or other workpieces which are symmetrical in height.
Description
Technical field
The present invention relates to a kind of fixture.
Background technology
Fixture refers to and be used for fixing processing object in machine-building process, makes it to occupy correct position, to accept the device of constructing or detecting.On lathe during processing work, the dimensions reaching drawing for making the surface energy of workpiece and specify, geometry and with the technical requirements such as the relative-position error on other surfaces, workpiece must be installed (location) before processing, clip (clamping).
Fixture of the prior art, when clamping work piece, easily produces or shift phenomenon, reduces the precision of converted products.If add man-hour in the enterprising perform hole of workpiece, groove class, lack the defect that effective location is easy to occur hole on workpiece, groove class position off-design requires, have a strong impact on product using function.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of differential mechanism to dismantle chuck assembly
To achieve these goals, present invention employs following technical scheme:
A kind of fixture, comprises pedestal, bevel gear wheel, claw and bevel pinion,
Described pedestal is circular cylinder, and pedestal inside is toroidal cavity, and pedestal end face is provided with the chute in several diametric(al)s,
The back side of described bevel gear wheel is provided with helicla flute, and bevel gear wheel is coaxially arranged in the annular cavity of pedestal and also can pivots, and helicla flute place faces up,
Described claw comprises base and holder, and holder is fixed on base, and base end face is provided with the groove agreed with mutually with helicla flute, and claw to be inlaid in chute by base and groove engages with helicla flute,
Described bevel pinion engages with bevel gear wheel, and line shaft one end is connected with bevel pinion, and the line shaft other end is through the through hole be located on pedestal sidewall and be connected with power source.
The described chute of pedestal end face and the base of claw are " ten " font, and the two closely cooperates and nested installation forms moving sets.
Described power source is motor, hand-operated device or spanner.
Described helicla flute distributes according to two-dimensional helical line.
Several chutes described are uniformly distributed at pedestal end face, and the quantity of claw is identical with the quantity of chute.
Described holder is inverted "L" shaped, and the cross bar of inverted "L" shaped holder is towards pedestal center.
Compared with prior art, the beneficial effect that possesses of the present invention:
The present invention is rotated by spiral fluted and equally distributed claw can be made to draw in center with identical speed, the clamping force of all directions is even, be applicable to the clamping processing of round piece or other high degree of symmetry workpiece, reach the effect of accurate positioning, make workpiece not easily produce inclination or shift phenomenon, improve the precision of processing.

Detailed description of the invention
Below by embodiment, technical scheme of the present invention is further elaborated.
Embodiment 1
A kind of fixture, comprises pedestal 4, bevel gear wheel 6, claw 2 and bevel pinion 8,
Described pedestal 4 is circular cylinder, and pedestal 4 inside is toroidal cavity, and pedestal 4 end face is provided with the chute 9 in several diametric(al)s,
The back side of described bevel gear wheel 6 is provided with helicla flute 10, and bevel gear wheel 6 is coaxially arranged in the annular cavity of pedestal 4 and also can pivots, and helicla flute 10 place faces up,
Described claw 2 comprises base 5 and holder, and holder is fixed on base 5, and base 5 bottom surface is provided with the groove agreed with mutually with helicla flute 10, and claw 2 to be inlaid in chute 9 by base 5 and groove engages with helicla flute 10,
Described bevel pinion 8 engages with bevel gear wheel 6, and line shaft one end is connected with bevel pinion 8, and the line shaft other end is through the through hole 3 be located on pedestal sidewall and be connected with power source.
The described chute 9 of pedestal 4 end face and the base 5 of claw 2 are " ten " font, and the two closely cooperates and nested installation forms moving sets.
Described power source is motor, hand-operated device or spanner.
Described helicla flute 10 distributes according to two-dimensional helical line.
Several chutes 9 described are uniformly distributed at pedestal 4 end face, and the quantity of claw 2 is identical with the quantity of chute 9.
Described holder is inverted "L" shaped, and the cross bar 1 of inverted "L" shaped holder is towards pedestal center.
Operation principle and process thereof:
During use, power source drives bevel pinion 8 to rotate by line shaft, and bevel pinion 8 drives bevel gear wheel 6 to rotate, and because the groove of base 5 bottom surface engages with helicla flute 10, spiral fluted rotarily drives claw and does in diametric(al) and move.When rotating forward, several claws draw in center and are clamped by gripped object, and during reverse rotation, gripped object unclamps away from center by claw.In Fig. 6,7 is the geared surface of bevel gear wheel.
