The specific embodiment
Explain further details in the face of the present invention down.
See also Fig. 1, it is the structural representation of lever meter table circle attaching/detaching apparatus of the present invention.Said lever meter table circle attaching/detaching apparatus comprises shirking grabs 2A, 2B, go up and down cover 3A, 3B, main body 4, spinning cover 7, fastening stud 8, spring 6 and mounting jaw 11A, 11B.Said spinning cover 7 is arranged on main body 4 upper ends, and is threaded with main body 4.Said fastening stud 8 is arranged on body interior, and is spirally connected with the main body internal thread.Said main body 4 lower ends are the sphenoid of two relative harvest dovetail grooves.In addition, main body 4 surfaces offer gathering sill 5, and are with spring 6.Said up-down cover 3A, 3B distributed and arranged grab 2A, 2B upper end shirking, and its other end is socketed in spinning through convex tendon and overlaps in 7 gathering sills 5, and lower surface contacts with spring 6.Said mounting jaw 11A, 11B are separately positioned on and shirk the step place, lower end of grabbing 2A, 2B separately, and flexible adjustable, thereby can cooperate interlock truck dead lever table table circle 1 with the lower end step of A, 2B.
Lever meter table circle attaching/detaching apparatus of the present invention adopts the principle of screw propulsion, and during dismounting table circle, the dovetail boss with lever meter table body 10 inserts in the dovetail groove 9 of apparatus main body 4 earlier, and the fastening stud 8 of screwing fastens as one lever meter table body 10 and apparatus main body 4.The spinning that turns clockwise cover 7; There are 7 pairs of up-down covers of this spinning cover 3A, 3B to press down; It is moved down, and the convex tendon in go up and down simultaneously cover 3A, the 3B is along the gathering sill 5 compression springs 6 of main body 4, be arranged on this moment shirking of cover 3A, 3B lower end grab 2A, 2B simultaneously downwards straight line move.Adjust to shirk and grab 2A, 2B in cover 3A, the last position of 3B of going up and down; When making it contact continued with lever meter table circle 1 and move down 3mm～4mm; The lower end step of grabbing 2A, the 2B active force to lever meter table circle is shirked in utilization; Make lever meter table circle and lever meter table body 10 break away from, thereby accomplish the work of dismounting lever meter table circle.
During installation, lever meter table circle is placed on mounting jaw 11A, 11B is last, is rotated counterclockwise spinning cover 7, and under the effect of spring 6, the cover 3A that goes up and down, 3B rise, and drives and shirk the mounting jaw 11A, the 11B that grab 2A, 2B below and rise simultaneously, and lever meter table circle is installed.Unscrew fastening stud 8 then, and mobile agent, make lever meter table body 10 break away from main body, thereby whole device is thrown off with the table body.
In addition, do following supplementary notes again to lever meter table circle attaching/detaching apparatus of the present invention:
(1) internal thread of spinning cover 7 acts on the external screw thread of main body 4 mutually, and the cover 7 of exerting pressure is moved down steadily.
(2) go up and down cover 3A, 3B is that axle sleeve type contact sliding fit with the cylindrical of main body 4, and the gathering sill on the main body 4 (groove) start-stop that matches with the convex tendon that goes up and down to put transfers to usefulness, and the cover 3A that promptly goes up and down, 3B is overlapped 7 and move up and down as straight line with exerting pressure, and does not follow its rotation.
(3) shirk and grab 2A, 2B and lever meter table circle 1 contact site and be circular-arc; Be that lever meter table loop diameter is when being 26mm; Shirk grab 2A, 2B contacts as shown in Figure 2 with lever meter table circle 1; Be that part covers contact between the two, both shirked and grabbed the fringe region that 2A, 2B do not cover lever meter table circle 1 surface fully.When lever meter table loop diameter is 30mm, shirks and grab 2A, 2B and contact as shown in Figure 3ly with lever meter table circle 1, is to contact fully between the two, has both shirked and has grabbed the fringe region that 2A, 2B cover lever meter table circle 1 surface fully.Therefore, detachable import at present of this device and homemade structure are the lever meter table circle of all specifications of attaching type, belong to a tool multi-purpose type device.
(4) lever meter installs therewith by dovetail boss and dovetail groove and cooperates, and is fastened as one by fastening stud 8.The dovetail boss of lever meter table body 10 inserts the dovetail groove 9 of apparatus main body 4, and the fastening stud 8 of screwing, lever meter clamping are easily and efficiently accomplished.
(5) 6 supports of spring, reset response.Be rotated counterclockwise spinning cover 7, at this moment, under the effect of spring 6, the cover 3A that goes up and down, 3B rise drive shirk grab 2A, 2B rises simultaneously.
Lever meter table circle attaching/detaching apparatus of the present invention in use, through rotation spinning cover, at cover 3A, the 3B of going up and down, gathering sill 5 with shirk the acting in conjunction of grabbing 2A, 2B, mounting jaw 11A, 11B, unload, install lever meter table circle.Changed original with the spiral shell cutter lever up, little copper hammer knocks; Phenomenon that the table circle that causes damages and indicator wrecks; Its reliable, stable, laborsaving, safety, making coarse, dangerous operational transition is civilized safety operation, improves maintenance qualification rate 30%; Improve 2～3 times of removal efficiencies, therefore have bigger actual application value.
