Abstract
The invention discloses a double-conical-surface pneumatic tensioning chuck and belongs to the field of tool clamps. The double-conical-surface pneumatic tensioning chuck is composed of a base, an air cylinder, an ejector rod, a double-conical-surface mandrel, supporting rods, tensioning claws and a shell. The three tensioning claws which are evenly distributed in the radial direction are installed on the chuck shell. Each tensioning claw is provided with two corresponding supporting rods. The two supporting rods on each tensioning claw make contact with two tensioning conical surfaces of the double-conical-surface mandrel respectively. During workpiece clamping, an air cylinder rod stretches and retracts to drive the ejector rod and the double-conical-surface mandrel to move, and the tensioning claws expand and contract by driving the supporting rods through the conical surfaces, so that a workpiece is tensioned or released; the double-conical-surface mandrel, the supporting rods, the tensioning claws and the shell can rotate along with the workpiece; the chuck is uniform in tensioning force and high in centering precision, and a tensioning mechanism is not prone to getting stuck.
Description
Technical field
The present invention relates to a kind of chuck, specifically employs cylinder, bipyramid center of area axle, strut and realizes to having with the pawl that rises
Hole type parts are clamped and a kind of chuck for loosening automatically, belong to frock clamp field.
Background technology
There is substantial amounts of part to have the hole being relatively large in diameter in the industrial production, Jing is often sharp for the processing, carrying to this class part
With the hole on part, using various chuck fixtures as positioning and the instrument for clamping.Chuck fixture has small volume, automatically
The advantages of centering, firm clamping, so in the industrial production application amount is very big.
Existing air spider, if desired rotates after parts fixation, and pneumatic action part follows chuck to rotate, and needs to compare
Complicated air distribution system, requirement on machining accuracy is higher, and volume is larger, working service inconvenience.
The content of the invention
For above-mentioned deficiency, the invention provides a kind of Double-conical-surface Pneumatic expanded chuck.
The present invention is achieved by the following technical solutions：A kind of Double-conical-surface Pneumatic expanded chuck, be by pedestal, cylinder,
Push rod, bipyramid center of area axle, strut, rise pawl and housing composition, it is characterised in that：Cylinder bolt is arranged on pedestal, push rod
Upper end is arranged on cylinder rod, and is locked with locking nut, and push rod bottom is provided with angular contact ball bearing, and bipyramid center of area axle passes through
Angular contact ball bearing and push rod connect, and strut one end with rise pawl is arranged on through the pilot hole on housing and by soket head cap screw
Together, the other end of strut and the taper-face contact of bipyramid center of area axle, are provided with back-moving spring on strut, and back-moving spring one end is pressed in
Case inside, housing is connected by bearing with pedestal.
3 rise by pawl radial equipartition on housing, and, with 2 struts are provided with, 2 struts are in back-moving spring for the pawl that rises per piece
In the presence of contact with 2 tensioner conical surfaces of bipyramid center of area axle respectively.
Housing is connected by bearing with pedestal, and bipyramid center of area axle is connected by angular contact ball bearing and push rod, clamping workpiece
After the completion of, bipyramid center of area axle, strut, the pawl that rises can follow workpiece with housing together with rotate.
The usefulness of the invention is 3 pawls that rise that radially uniform distribution is provided with housing, and the pawl that rises per piece is respectively mounted
There are 2 struts, 2 struts contact respectively with 2 tensioner conical surfaces of bipyramid center of area axle, workpiece uniform force when making tensioner is fixed
Heart high precision, and tension mechanism be difficult it is stuck.Housing is connected by bearing with pedestal, and bipyramid center of area axle passes through angular contact ball axle
Hold and push rod connection, therefore by together with after the completion of clamping workpiece, bipyramid center of area axle, strut, the pawl that rises can follow workpiece with housing
Rotation, cylinder, push rod and pedestal do not follow workpiece to rotate, and eliminate the air distribution system of complexity, make clamp structure simple, cost
It is low.
Description of the drawings
Accompanying drawing 1 is the front view of present configuration, and accompanying drawing 2 is the upward view of Fig. 1.
In figure, 1, rise pawl, 2, housing, 3, strut, 4, back-moving spring, 5, bipyramid center of area axle, 6, angular contact ball bearing, 7, top
Bar, 8, soket head cap screw, 9, cylinder, 10, locking nut, 11, pedestal, 12, bearing.
Specific embodiment
A kind of Double-conical-surface Pneumatic expanded chuck, be by pedestal 11, cylinder 9, push rod 7, bipyramid center of area axle 5, strut 3, rise pawl 1
With the composition of housing 2, it is characterised in that：The bolt of cylinder 9 is installed on the base 11, and the upper end of push rod 7 is arranged on cylinder rod, and
Locked with locking nut 10, the bottom of push rod 7 is provided with angular contact ball bearing 6, bipyramid center of area axle 5 passes through the He of angular contact ball bearing 6
Push rod 7 connects, and the one end of strut 3 is through the pilot hole on housing 2 and is installed together with the pawl 1 that rises by soket head cap screw 8, strut
3 other end and the taper-face contact of bipyramid center of area axle 5, are provided with back-moving spring 4 on strut 3, the one end of back-moving spring 4 is pressed in housing
2 inner sides, housing 2 is connected by bearing 12 with pedestal 11.
3 rise by the radial equipartition of pawl 1 on housing 2, and the pawl 1 that rises per piece is being resetted with 2 struts, 2 struts are provided with
2 tensioner conical surfaces in the presence of spring 4 respectively with bipyramid center of area axle 5 contact.
Housing 2 is connected by bearing 12 with pedestal, and bipyramid center of area axle 5 is connected by angular contact ball bearing 6 and push rod 7, work
After the completion of part clamping, bipyramid center of area axle 5, strut 3, the pawl 1 that rises can follow workpiece with housing 2 together with rotate.
The chuck is in use, main actions flow process is：The action of cylinder 9 makes cylinder rod retract, and drives push rod 7 and Double-conical-surface
Move on heart axle 5, the pawl 1 that rises in the presence of back-moving spring 4 shrinks, and the pawl 1 that now will rise stretches into workpiece hole, and the action of cylinder 9 makes cylinder
Bar stretches out, and drives push rod 7 and bipyramid center of area axle 5 to move down, and radially outer shifting makes the spreading of pawl 1 that rises to drive strut 3, by Workpiece clamping,
Because housing 2 is connected by bearing 12 with pedestal 11, bipyramid center of area axle 5 is connected by angular contact ball bearing 6 and push rod 7, bipyramid
Center of area axle 5, strut 3, the pawl 1 that rises rotate together with can following workpiece with housing 2, and when needing to loosen workpiece, the action of cylinder 9 makes cylinder
Bar is retracted, and is driven and moved on push rod 7 and bipyramid center of area axle 5, and the pawl 1 that rises in the presence of back-moving spring 4 shrinks, and removes workpiece.
For the ordinary skill in the art, teaching of the invention, without departing from the present invention principle with
In the case of spirit, changes, modifications that embodiment is carried out, replace and modification still fall within protection scope of the present invention it
It is interior.
