Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 to Fig. 5 is structural representation of the present utility model.
Reference numeral is wherein: product workpiece A, inclined-plane B, circular arc drag hook C, chuck body 1, clamping cylinder 2, compression resetting block 3, guiding sliding chamber 3a, link slot 3b, tapered wedges 31, auxiliary briquetting 32, movable locking 4, fixed dam 5, steady pin 6, cylinder connecting rod 7.
Fig. 1 to Fig. 5 is structural representation of the present utility model, as shown in the figure, a kind of jaw type self-centering clamping structure of the present utility model, comprise the chuck body 1 coordinated with one end supporting and location of product workpiece A and the clamping cylinder 2 be vertically mounted on below this chuck body 1, penetratingly in chuck body 1 be shaped with guiding slide opening, slide in this guiding slide opening to be provided with and control by clamping cylinder 2 the compression resetting block 3 that moves up and down, and the symmetrical movable locking 4 being provided with two sides jaw types clamping product workpiece A from product workpiece A in chuck body 1, the center compressing resetting block 3 is processed with the tapered wedges 31 that slidingtype synchronously extrudes the movable locking 4 opposite direction rotating clamping promoting both sides.In prior art, some product workpiece because of structure special, one end can only be adopted unsettled, and the mode that the other end is fixedly clamped is processed.Because the processing end of this series products cannot clamp in front, and supporting pin can not be added bottom product, therefore make the product free degree not be restricted completely, cause product other end end face to add and easily occur problem such as shake cutter, distortion etc. man-hour.The utility model utilizes compression resetting block 3 and movable locking 4 to form Wedge type clamping structure, by clamping cylinder 2 thrust upwards, be converted into the blessing power to product workpiece A two sides of jaw type and downward clamping force, not only stroke is short in the design of wedge structure, and saving space, effectively reduce the manufacture difficulty of fixture, and product workpiece A can also be made in the process of clamping to have because of the difference of the stressed size in both sides the self centering ability that suitably horizontally slips.This jaw type self-centering clamping structure of the present utility model, machining area can be needed special at product and inconvenient front side supports, centering and compression clamp product, solve and cause shaking cutter, problem on deformation because product one end is unsettled, and wedge clamping structure, only need very little cylinder just can clamp product, cost-saving.
In embodiment, chuck body 1 is provided with fixed dam 5, this fixed dam 5 is provided with and rotates with movable locking 4 steady pin 6 worn.
In embodiment, chuck body 1 is provided with four pieces of fixed dams 6, the equal activity orientation of each movable locking 4 is between two pieces of fixed dams 5.
The center of movable locking 4 is shaped with the shaft hole that steady pin 6 wears, and this movable locking 4 can be axis of rotation restricted rotational movement with steady pin 6.
In embodiment, compress the both sides of resetting block 3 and be processed with and coordinate with movable locking 4 back side auxiliary briquetting 32 limiting movable locking 4 slewing area, and assist to be formed between briquetting 32 and tapered wedges 31 and prevent movable locking 4 vibration to lead cunning chamber 3a.
Steady pin 6 is fixed in two pieces of fixed heads 5 through movable locking 4, and controls the height of movable locking 4, makes its part be placed in the sliding chamber 3a of guiding of compression resetting block 3, avoids movable locking 4 to be free to slide along steady pin 6.
In embodiment, the both sides of tapered wedges 31 are shaped with the inclined-plane B be slidably matched with respective activity latch segment 4, and the longitudinal sectional view of this tapered wedges 31 is trapezium structure.
In embodiment, the upper end of auxiliary briquetting 32 is shaped with circular arc drag hook C, and this circular arc drag hook C helps out matching with the back side of movable locking 4 of formula.
In embodiment, the front end of clamping cylinder 2 is installed with cylinder connecting rod 7, and the bottom surface compressing resetting block 3 is shaped with the link slot 3b be fixedly linked with cylinder connecting rod 7 front end.
The course of work of the present utility model is as follows.
As structural representation when Fig. 2 and Fig. 3 is utility model works state, Fig. 6 is that product workpiece is from compressing the structural representation held and see.As shown in the figure, after this procedure of product workpiece A machines, clamping cylinder 2 rollback, the tight resetting block 3 of the drop-down dynamic pressure of cylinder connecting rod 7, make its relaxation exercise latch segment 4, compress the circular arc drag hook C special operations latch segment 4 compressing resetting block 3 both sides in the drop-down process of resetting block 3 and be relaxed to reset mode, now, product workpiece A can be taken out.
In like manner product to be processed workpiece A is placed in chuck body 1, clamping cylinder 2 propulsion cylinder connecting rod 7, in this process, the thrust being subject to cylinder connecting rod 7 compresses the inclined-plane B Compressive activities latch segment 4 of resetting block 3 tapered wedges 31, makes it rotate clamping product workpiece A around steady pin 6.
Although the utility model illustrates by reference to preferred example and describes, those skilled in the art should be understood, and in the scope of claims, can do the various change in form and details.
