In to the detection of auto parts, first need part clamping and positioning, and then carry out the detection of its end face or position, hole, but existing part clamping device majority can only clamp one end of part, running into one end clamping of larger-size part can cause the center of gravity of part to occur deviation, easily shake, be unfavorable for follow-up detection, once and part just can not move after clamping, make troubles will to like this installation of cubing parts and the dismounting of part of its periphery, between cubing accessories and parts, there will be mutual interference, to subsequent detection, make troubles.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of movable double arm swing clamping device, utilize scissors principle to clamp the two ends of part, clamp solid and reliablely, and can to whole clamp assembly, move with cylinder, make can not produce interference between part and detection part.
The utility model solves the technical scheme that its technical problem adopts: clamping device comprises installs dull and stereotyped, guide rail and cylinder, in the dull and stereotyped upper surface of installation, be furnished with pair of guide rails, the upper end of this guide rail slidably connects clamp assembly installing plate, upper end one side of this clamp assembly installing plate is horizontally installed with clamping cylinder, opposite side is vertically provided with fulcrum piece, between fulcrum piece and clamping cylinder, should leave enough activity spaces;
Wherein the extension bar of clamping cylinder stretches out and contiguous block is installed to fulcrum piece, the bilateral symmetry of this contiguous block is furnished with connecting rod and is rotationally connected with one end of connecting rod, the bilateral symmetry of described fulcrum piece is furnished with jig arm and is rotationally connected with the middle part of jig arm, the other end of one end of described jig arm and the connecting rod of homonymy is rotatedly connected, this structure is to utilize lever principle, by cylinder, come the movement of control connection piece to drive the activity of connecting rod, connecting rod drives jig arm to rotate around the two ends of fulcrum piece, distance between the free end of jig arm just changes along with the rotation of jig arm, realization is to the clamping of part and unclamp,
In order to realize the control moving horizontally of the part to clamping, in the dull and stereotyped lower end of installation, be horizontally installed with promotion cylinder, this extension bar that promotes cylinder is connected with clamp assembly installing plate by riser, promotes cylinder and guide rail parallel, realizes the synchronizing moving that promotes cylinder and clamp assembly installing plate.
As a kind of of clamping device described in the utility model, supplement, at the free end of jig arm, clamping and positioning piece is installed relatively, this clamping and positioning piece can increase the accuracy of part clamping and positioning and reliability.
Another kind as clamping device described in the utility model supplements, and the both sides of described fulcrum piece are arcwall face with the sidewall that is connected of jig arm, and arcwall face is conducive to jig arm and rotates around fulcrum piece.
As also having of clamping device described in the utility model is a kind of, supplement, the two ends of described guide rail are provided with block, and by clamp assembly installing plate, the sliding distance on guide rail limits in the existence of this block, improves the security of sliding.
As clamping device described in the utility model a kind of preferably, maximum opening angle between described jig arm is 60 °, it is to draw according to the length of the operating range of contiguous block and connecting rod that opening angle is set to 60 °, and this angle and enough clamping and positioning to part, the rotational travel of jig arm is shorter, and clamping efficiency is higher.
Utilize above-mentioned technical scheme, realized part, particularly the fast positioning clamping of larger-size part, prevents the appearance of interference, safe and reliable, greatly improves the clamping efficiency of sleeve pipe, improves the accuracy of subsequent detection.
