Description
[technical field]
The utility model relates to a kind of anchor clamps, especially relates to a kind of anchor clamps with workpiece location and fixing test IC chip carrier.
[background technology]
The anchor clamps of general workpiece are applied in the manufacturing operation at large, are used for workpiece being kept and being clamped on the stationary fixture, so that workpiece is carried out the processing of machine work or alternate manner.The anchor clamps of typical workholder such as vice and so on, it is a kind of universal chuck, can adapt to various workpiece.But this universal chuck workpiece loading and unloading is wasted time and energy, and workpiece can not accurately locate, and clamping force is also wayward, it is excessive or too small to tend to take place clamping force, the generation workpiece is crushed or in the problem that adds the displacement in man-hour, throughput rate is low, and the precision of processing also is difficult to guarantee.Therefore, when producing in enormous quantities, often will be according to size, shape and the characteristics of concrete workpiece, the anchor clamps of design specialized are to improve machining precision and throughput rate.
Existing a kind of manual anchor clamps in order to location and fixing test IC chip carrier, mainly by pedestal, latch mechanism, platen, handgrip four most of compositions, its primary structure is: latch mechanism belongs to a four-bar linkage structure, have first, the second two moving fulcrums and the 3rd, the 4 two movable fulcrum, Di Bu first fulcrum wherein, second fulcrum connects and composes first connecting rod and is fixed on the pedestal, first fulcrum and the 3rd fulcrum connect and compose second connecting rod, second fulcrum and the 4th fulcrum constitute third connecting rod, the 3rd fulcrum and the 4th fulcrum constitute the 4th connecting rod, wherein, platen is connected with third connecting rod, handgrip is connected with the 4th connecting rod, and the movable fulcrum of second connecting rod and the 3rd fulcrum on the 4th connecting rod all are fixed on the handgrip.
Four-bar linkage structure is the important structure of described anchor clamps, when handgrip is depressed, the 4th connecting rod of handgrip interlock promotes platen and compresses test I C chip carrier downwards, just be pressed on by second connecting rod on the third connecting rod that constitutes by the 4th fulcrum and second fulcrum with form against, at this moment, the second connecting rod that the 3rd fulcrum and first fulcrum constitute is by vertically becoming heeling condition, and the third connecting rod that the 4th fulcrum and second fulcrum constitute becomes vertical state by inclination; And when taking out test I C chip carrier, the second connecting rod that is made of the 3rd fulcrum and first fulcrum breaks away from supporting of third connecting rod that the 4th fulcrum and second fulcrum are constituted earlier, the second connecting rod that the 3rd fulcrum and first fulcrum constitute becomes vertical state by inclination, the third connecting rod that the 4th fulcrum and second fulcrum constitute is by vertically becoming heeling condition, and be that handgrip drive platen makes it to break away from test I C chip carrier this moment.
The main deficiency that existing above-mentioned anchor clamps exist is:
1. operating personnel need the consistent state that keep pulling at the thumb and the forefinger of tension and compression handgrip right hand to the process of correct position, pedestal is fixed on the worktable, body is very approaching because first, second fulcrum disseats, when causing handgrip to be depressed, the finger section branch that is positioned at handgrip below bumps to worktable, and when lifting handgrip, the gap between handgrip below and the worktable is very little, make operating personnel when lifting handgrip, not have the space to set about, very inconvenient.
2. at the handle structure of the anchor clamps of four-bar linkage structure inconvenience when the operation, handle structure is easier to do to avoid design, and the height of increasing between handgrip and the worktable get final product, has occupied the space that anchor clamps occupied but establish like this to change, and is unfavorable for the space miniaturization.
Therefore, as seen from the above, still there is disappearance in the above-mentioned technology of commonly using, and the existing a kind of new anchor clamps of design that need are to overcome above deficiency.
