Described clamping sleeve profile pref. cylindrical, the top of clamping sleeve can be provided with and be used for the base annular lip of clamping fixture base plate together.
Described locating hole is the circular hole by taper reducing inclined-plane reducing preferably.
The lateral surface of described clamping sleeve bottom is provided with the cannelure that is embedded with O type circle, the bottom of described cannelure respectively with the roof intersection of described each sidewise hole.
Described base can be divided into base body and lock tube two parts, and described lock tube is the shell of described locating hole, is embedded on the described base body.
During use the anchor clamps base plate is placed on the base, the endoporus of anchor clamps base plate is alignd with the locating hole of base, anchor clamps base plate endoporus is passed in the clamping sleeve lower end insert locating hole on the base, by modes such as rotations depression bar is moved down, the depression bar lower end with extrusion ball to pressing down, and then by extrusion ball with each lock ball balancedly to extrapolation, the outside active force that contacts with reducing inclined-plane on the base when mobile and apply a perpendicular and this inclined-plane to this inclined-plane of lock ball, the component of this active force upwards pushes away base, by base and clamping sleeve top the anchor clamps base plate is clamped thus.By the clamping sleeve external diameter rationally being set, can carry out accurate localization to the anchor clamps base plate with the fit clearance between anchor clamps base plate endoporus and the base locating hole; Even distribution by each sidewise hole can guarantee the harmony that base is stressed, avoids causing the skew of anchor clamps base plate because of unbalance stress; Owing on the cannelure of clamping sleeve side, be provided with O type circle, and the part that intersects by ring shaped slot and each sidewise hole makes O type circle be exposed at the sidewise hole top, promptly avoided lock ball to roll out thus from sidewise hole, lock ball to outside extruding forms inside elastic force again, can automatically lock ball be rolled back when dismounting; Owing to be provided with lock tube, can adopt different materials to make base body and lock tube respectively, so that reduce production costs when lock tube has superperformance guaranteeing, increase the service life; Because depression bar has adopted screw form,, be very easy to practical operation thus as long as the rotation depression bar just can make depression bar move up and down.The utility model is simple in structure, it is little to take up room, the location accurately, clamping is firm, is very easy to use, improved production efficiency.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
The specific embodiment
Referring to Fig. 1, clamping sleeve 2 passes the endoporus of anchor clamps base plate 5 and the locating hole of base, all adopts the very little precision-fit in gap between its lateral surface and two holes, to reach pinpoint purpose.The vertical through holes bottom of clamping sleeve is the ball chamber, this ball chamber is communicated with three sidewise holes, be provided with three steel ball and steel balls in the space that ball chamber and sidewise hole constitute as extrusion ball 7 as lock ball 4, wherein extrusion ball is positioned at vertical through holes (ball chamber), and the part of lock ball (can be most of) can be positioned at each self-corresponding sidewise hole, another part is positioned at vertical through holes (ball chamber), the top of extrusion ball contacts with the lower surface of depression bar 1, the bottom contacts with each lock ball respectively, since extrusion ball with the contact site of lock ball not on the perpendicular diameter of these balls, so the power that extrusion ball is applied on each lock ball is an oblique power, lock ball outwards squeezes in the direction that the effect lower edge of this oblique power sidewise hole limits, just be positioned at sidewise hole outside the reducing inclined-plane contact and form active force the reducing inclined-plane, under the situation of not considering stiction, this active force is generally perpendicular to and the contacted reducing of lock ball inclined-plane, make base upwards move or form power upwards with respect to clamping sleeve, together the anchor clamps base plate is tightly clamped with clamping sleeve thus.
The clamping sleeve top should be provided with the compressing member relative with susceptor surface, is used for together the anchor clamps base plate being clamped with base.Facility in processing and the use can be designed to from the clamping sleeve top side compressing member to the annular lip that extends out usually.
For easy to operate, depression bar adopts screw form usually, and is threaded with vertical through holes.
The O type circle 3 (can adopt rubber ring) that is positioned at cannelure is exposed at each sidewise hole, and retaining avoids lock ball to roll out in the outside of lock ball.Stressed outside when mobile when lock ball, promote the O type circle of retaining and together move in its outside, after the power that lock ball is subjected to was eliminated, the elastic force of O type circle can push inward lock ball.
Before the clamping device base plate, be in the state that unclamps between depression bar and the steel ball, four steel balls all do not stress, and are in free state in ball chamber and sidewise hole restricted portion.During installation, anchor clamps base plate endoporus is aligned the back with the locating hole on the base insert clamping sleeve, owing to all adopt the very little precision-fit in gap between clamping sleeve and anchor clamps base plate endoporus and the base locating hole, can accurately be positioned at the anchor clamps base plate on the base, the threaded depression bar of turn then, depression bar promotes three equally distributed lock balls on circumference by extrusion ball, lock ball is held out against on the reducing inclined-plane of lock tube, outside and the constraint reaction vertically downward of generation level, clamping sleeve firmly is clamped in the anchor clamps base plate on the base, thereby realizes clamping.During dismounting, unclamp depression bar, four stressed releasings of steel ball, the state that affranchises, clamping sleeve just can take out from locating hole like a cork.
For the consideration on the cost, base designs can be become two parts, a part is the lock tube 8 that constitutes the locating hole shell, and this part can adopt the steel of high rigidity, high abrasion to make, another part is the base body 6 that is used to embed lock tube, and this part can adopt the lower steel of price to make.
