Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention done concrete detailed description further.
As Figure 1-Figure 4, a kind of positioning clamping device, including for coordinating the base plate 1 installed with lathe and being arranged on the location-plate 6 of base plate 1 upper surface, location-plate 6 relative to base plate 1 with the centrage of the mandrel 10 that is perpendicular to base plate 1 setting for centre of gyration line.
Base plate 1 is provided with the U-shaped ear mount 11 for being connected with lathe, utilizes this U-shaped ear mount 11, adopt T-bolt that base plate 1 can be made to be connected with lathe (milling machine, drilling machine, boring machine, lathe etc.).
The jointed shaft I 2 passing through to be perpendicular to mandrel 10 on base plate 1 is provided with bolt 3, and described bolt 3 one end is connected to the sleeve 301 installed that matches with jointed shaft I 2, and the other end of bolt 3 is for being provided with the externally threaded end of thread 303.
The positioning boss 302 of annular it is provided with between the end of thread 303 and sleeve 301, the outer peripheral face A of positioning boss is locating surface, the outer peripheral face A of positioning boss can be the face of cylinder, it is also possible to being the sphere in cydariform, position corresponding with bolt about 3 on location-plate 6 is provided with open slot 12.
The ymmetry center plane of open slot 12 is through the centrage of mandrel 10, described open slot 12 is divided into lower segment groove 12a and epimere groove 12b along location-plate 6 thickness direction, lower segment groove side B is perpendicular with the bottom surface of location-plate 6, and the distance between two lower segment groove side B tapers into from outer end to the inner, make lower segment groove 12a tapered.
Epimere groove 12b is the kidney-shaped of outer end opening, say, that epimere groove 12b profile is a waist through hole with a section of arc one end.
Angle between two lower segment groove side B meets and the location that coordinates between positioning boss 302, and the width of epimere groove 12b meets the fixing of the end of thread 303.
" outward " as herein described refers to the outer peripheral edge of location-plate 6, and " interior " refers to the centrage of location-plate 6.
When the present invention uses, make bolt 3 be rotated up around jointed shaft I 2, slightly firmly make the outer peripheral face A and two lower segment groove side B of the positioning boss on bolt 3 keep in touch.Then rotating clamp jack panel 5, makes base plate 1 and location-plate 6 link together.
If desired, can separately set up resilient clamping mechanism and be pressed on bolt 3, so that the two sides of bolt 3 and lower segment groove 12a are kept in touch.Open slot on location-plate 6 can be arranged as required to as multiple, to meet the needs carrying out multistation processing on same workpiece.In embodiment as depicted in figs. 1 and 2, the open slot of setting is 8, can meet the processing to 8 stations maximum on same workpiece.Specifically, after a station process finishing, unclamp binding nut 5, under making bolt 3 naturally turn；Around mandrel 10 rotational positioning plate 6, making next open slot 12 turn to the position of bolt 3, location clamps again.
In order to strengthen the effect that is fixedly clamped between location-plate 6 and base plate 1 further, position symmetrical with bolt 3 on base plate 1 is additionally provided with fishbolt 8 by pin shaft II 9, fishbolt 8 matches with a corresponding open slot and realizes the further clamping to location-plate 6, fishbolt 8 can adopt the common fishbolt without positioning boss, or adopt the structure the same with bolt, but being not used as the locating surface of location, namely fishbolt only serves the effect of clamping.
Processed workpiece can be directly connected to position processing with location-plate 6, it is also possible to present embodiment as depicted, makes a rebound 7 fix with location-plate 6 and is connected, is then connected on rebound 7 by processed workpiece and positions processing.
In order to strengthen the reliability that the present invention uses, make the outer peripheral face A of positioning boss relatively low in the accuracy of manufacture or still ensure that bolt 3 meets the purpose of location clamping after abrasion, can adopt the packing ring 4 with sphere-contact face and the same binding nut 5 with sphere-contact face with the use of, two sphere-contact faces one are convex one recessed with the use of the effect that can play regulation of mental activities, thus realizing reliable grip.
The mounting groove 13 for installing jointed shaft I 2 it is provided with in the periphery of base plate 1, two mounting groove sidewall E are respectively equipped with supported hole, the two ends of jointed shaft I 2 are supported in two supported holes, the sleeve 301 of bolt one end is set in jointed shaft I 2 outside and between two mounting groove sidewall E, is matched in clearance between the end face of sleeve 301 and two mounting groove sidewall E.
At least one end face at sleeve 301 is provided with the oil groove 301a of annular, as shown in Figure 5 and Figure 6.Lubricating oil can be added in use toward oil groove 301a.Reduce the abrasion of the end face of sleeve 301.
The outer peripheral face of sleeve 301 can be cylindrical or cydariform.
Can also, the cross section of sleeve 301 is the U-shaped of upper end closed, as shown in Figure 8.
When sleeve 301 is in cydariform (namely the outer peripheral face F of sleeve is the sphere of cydariform), such as Fig. 7.Adopting this structure, as shown in Figure 4, the outer peripheral face F of sleeve and mounting groove sidewall E meets at m point, and namely mounting groove sidewall E is the shortest is worked into herein；And when sleeve is cylindric, namely when the outer peripheral face F of sleeve is cylindrical, and when the outer peripheral face maximum gauge of sleeve is identical, the outer peripheral face F of sleeve and mounting groove sidewall E meets at n point, the shortest need of length of mounting groove sidewall E are worked into herein, say, that: the equal cydariform sleeve of maximum gauge, compared with cylindrical sleeve, adopts the sleeve of cydariform, the difficulty of processing of mounting groove this segment length of processing capacity mn of mounting groove sidewall E can be reduced, thus can be reduced.
In actual application, can also processing a technical gaps 14 on the side of mounting groove 13, in order to the installation of jointed shaft I 2, present embodiment has technical gaps 14 in the both sides proportion by subtraction processing of mounting groove 13.
Fishbolt 8 can adopt the mounting structure identical with bolt 3.
On location-plate 6, being provided with, corresponding to the location-plate hypomere of height residing for lower segment groove 12a, the counterbore 601 being easy to lower segment groove 12a processing, the terminal of lower segment groove 12a intersects with counterbore 601 passes through.
