Abstract
The invention discloses a fixed type automatic chuck. The fixed type automatic chuck comprises an ejector pin, wherein the ejector pin is inserted in a heart-shaped chuck of a machine tool; a step is arranged at the front end of the ejector pin; a fixing plate sleeves the step and is connected with the step by a square key; an outer ferrule sleeves the outer side of the fixing plate and is connected with the outer side of the fixing plate by a bearing; three irregular clamping plates of which one sides are heavy are distributed at the front of the fixing plate in the radial direction; one side, which faces the center, of each clamping plate is an arc-shaped clamping surface; a rotary center hole is formed in the other side, which is close to the corresponding arc-shaped clamping surface, of each clamping plate; distances from the rotary center hole of each clamping plate to two ends of the corresponding arc-shaped clamping surface of the clamping plate are different; and a rotating shaft which is fixed on the fixing plate is arranged in each rotary center hole. The fixed type automatic chuck has the advantages that the rotating shafts rotate forwards and reversely along with the ejector pin and drive the clamping plates to rotate, one sides of the clamping plates are heavy, the center of gravity of each clamping plate is different from the center of gravity of the corresponding rotating shaft, so that the clamping plates deflect, the diameter of a tangent circle formed by the three arc-shaped clamping surfaces can be increased or reduced, and a workpiece can be clamped or released; and an opening groove and a pull sliding rod have a guiding effect.
Description
Technical field
The present invention relates to the auxiliary device on a kind of non-standard equipment, specifically a kind of fixed automatic clamping chuck.
Background technology
There is a chuck, for folder when processing on cylindrical grinder or other machine components process equipment
Take workpiece, such as scroll chuck, heart carrier for bolt are first-class, be required for artificial gripping.
Non-standard equipment is used to replace artificial equipment, has minimizing labor intensity, the effect of lifting productivity effect, one
Operative employee can operate several equipment simultaneously, if workpiece also needs to artificial gripping one by one, then productivity effect is to carry
Do not rise.
The application have developed a kind of outside in chuck for equipment, has the chuck of automatic clamping workpiece.
Content of the invention
It is not enough that the present invention is directed to prior art, provide a kind of can substitute artificial, can be automatic in lathe rotating
Grip part to be processed and the fixed automatic clamping chuck automatically unclamping the part machining.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals: a kind of fixed automatic folder
Head includes a thimble being inserted on the heart carrier of lathe, and the front end of described thimble is provided with step, on described step
It is cased with fixed disk and is connected with square key, the outside of described fixed disk is cased with outer collar and is connected with bearing, described fixation
The front of disk is radially distributed with three unilateral irregular material folding plates laid particular stress on, and described material folding Ban Chao center side is arc
Material folding face, is provided with a rotation center hold near described arc material folding face side, described rotation center hold with described
The distance at the two ends in arc material folding face is inconsistent, and described center of rotation in the hole is provided with one and is fixed on described fixed disk
Rotating shaft.
One annular protrusion is provided with the upper edge of the base edge of described fixed disk and described outer collar, described
Bearing be clipped between the annular protrusion described in two.
The outer side edges of described material folding plate, along being above provided with open slot, are provided with one and are fixed on institute in described open slot
Slide bar is pulled out in the outer collar stated.
The front of described material folding plate is provided with a center the cover plate in hole, and described cover plate is spun on described outer collar
Front end.
Described thimble is taper, and described thimble is cased be connected disk and a shrouding for outer collar.
The present invention compared with prior art, has the advantages that 1) rotating shaft with thimble rotating, drives material folding plate
Rotate, material folding plate is unilateral to lay particular stress on, and center of gravity is inconsistent with rotating shaft so that material folding plate deflects, the arc material folding face described in three
Formed cuts diameter of a circle and can become big or diminish, to clamp or to unclamp workpiece；2) open slot plays guide effect with pulling out slide bar.
Brief description
Fig. 1 is the overall structure diagram of the embodiment of the present invention.
Fig. 2 is the profile of the embodiment of the present invention.
Fig. 3 is the part explosive view of the embodiment of the present invention.
Specific embodiment
With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings: referring to shown in Fig. 1 ~ 3, in figure
Mark is as follows: thimble 1, step 1a, fixed disk 2, square key 3, outer collar 4, annular protrusion 4a, bearing 5, material folding plate 6, arc material folding
