The specific embodiment
For making technological means of the present utility model, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
An embodiment of the present utility model is:
A kind of hold down gag, comprises frame 1, press plate mechanism and driving mechanism.Press plate mechanism comprises two sub-press plate mechanisms, i.e. the first press plate mechanism and the second press plate mechanism, and the first press plate mechanism and the second press plate mechanism lay respectively at the both sides, front and back of frame 1.The first press plate mechanism comprises the first left pressing plate 2, the first right pressing plate 3, the first anticlockwise pull bar 4, the first right rotation pull bar 5 and the first pressing plate swing arm 6.The second press plate mechanism comprises the second left pressing plate 7, the second right pressing plate 8, the second anticlockwise pull bar 9, the second right rotation pull bar 10 and the second pressing plate swing arm 11.Driving mechanism comprises threaded rod 12, thread bush 13, active swing arm 14 and swing arm spindle nose 15.Threaded rod 12 is arranged in frame 1 by upper cover 16 and lower cover 17 position limitations, but can rotate.Thread bush 13 is sleeved on threaded rod 12, and by rotation threaded rod 12, thread bush 13 moves up and down on threaded rod 12.Thread bush 13 is arranged among initiatively swing arm 14.The center of the first pressing plate swing arm 6 and the second pressing plate swing arm 11 is all provided with groove, and two swing arm spindle noses 15 are arranged on respectively among groove separately.The first pressing plate swing arm 6 and the second pressing plate swing arm 11 are separately take a swing arm spindle nose 15 as fulcrum support is in active swing arm 14.The first anticlockwise pull bar 4, the first right rotation pull bar 5 are supported on the two ends, left and right of the first pressing plate swing arm 6 rotationally.The second anticlockwise pull bar 9 and the second right rotation pull bar 10 are supported on the two ends, left and right of the second pressing plate swing arm 11 rotationally by spring 20.The first left pressing plate 2 is fixedly mounted on the upper end of the first anticlockwise pull bar 4, and the first right pressing plate 3 is fixedly mounted on the upper end of the first right rotation pull bar 5.The second left pressing plate 7 is fixedly mounted on the upper end of the second anticlockwise pull bar 9, and the second right pressing plate 8 is fixedly mounted on the upper end of the second right rotation pull bar 10.On the first anticlockwise pull bar 4, the first right rotation pull bar 5, the second anticlockwise pull bar 9 and the second right rotation pull bar 10, be all provided with helicla flute 18, locating pin 19 is fixedly mounted in frame 1 through helicla flute 18.
While wishing clamping work pieces, rotation threaded rod 12, thread bush 13 and threaded rod 12 are threaded engagement, thread bush 13 moves downward on threaded rod 12.Therefore, initiatively swing arm 14 moves down together under the drive of thread bush 13, thereby drives two swing arm spindle noses 15 to move down.Under swing arm spindle nose 15 drives, the first pressing plate swing arm 6 and the second pressing plate swing arm 11 also move down, thereby drive the first anticlockwise pull bar 4, the first right rotation pull bar 5, the second anticlockwise pull bar 9 and the second right rotation pull bar 10 and the first left pressing plate 2, the first right pressing plate 3, the second left pressing plate 7, the second right pressing plate 8 to move down.Meanwhile, because the first pressing plate swing arm 6 and the second pressing plate swing arm 11 are all only take a swing arm spindle nose 15 as the strong point, under lever principle effect, therefore the first pressing plate swing arm 6 and the second pressing plate swing arm 11 can swing up and down take swing arm spindle nose 15 separately as fulcrum.Same principle, the first press plate mechanism and the second press plate mechanism swing up and down take thread bush 13 as fulcrum.Can realize thus the first left pressing plate 2, the first right pressing plate 3, the second left pressing plate 7, the second right pressing plate 8 and in the time that threaded rod 12 rotates, move down different distance.I.e. in the time that one of them pressing plate clips to workpiece (now this pressing plate is zero to the clamping force of workpiece substantially), can realize other pressing plates continuation execution and press down shift action, until all pressing plates are all pressed onto workpiece.Now four pressing plates apply clamping force to workpiece simultaneously, have improved production efficiency and have reduced artificial manipulation strength, are conducive to improve the machining accuracy of workpiece.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand, the utility model is not restricted to the described embodiments, in above-described embodiment and description only for principle of the present utility model is described, under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all belong to the utility model scope.The claimed scope of utility model is defined by claims and the equivalent thereof of appendix.
