Patent announcement CN201529885U, the day for announcing is on July 21st, 2010, the utility model title is the horizontal fast compressing device of weld jig, and it comprises base, is fixed with bearing in the base upper surface, be connected with handle by bearing pin on the bearing, handle is provided with through hole, and through hole connects connecting plate by bearing pin, and arcuation connecting plate two ends join with handle and axle respectively, handle links to each other with the bearing that is fixed on the installation of base upper end by bearing pin, and the right-hand member position of axle is provided with base plate.The hold down gag of this structure is difficult to guarantee the requirement of welding locating accuracy and has increased personnel labor.
Summary of the invention
The utility model is vertically put into workpiece before for the required precision that guarantees to weld the location and compress and welding, and the vertical workpiece that takes out in welding back improves welding production efficiency, and a kind of cylinder hold-down mechanism is provided.
The utility model for the technical scheme that solves above-mentioned technical purpose and adopt solves is: a kind of cylinder hold-down mechanism, constitute by angle bearing and the clamping cylinder that is arranged on the bearing of angle, described angle bearing is made of base and support arm, base and support arm are structure as a whole, support arm is provided with pressed seat, described pressed seat is fixedlyed connected with support arm, the intersection of base and support arm is tiltedly installed with the clamping cylinder, be connected with the joint connecting rod on the motion bar of clamping cylinder, the other end of joint connecting rod is fixed with pressure strip, pressure strip and pressed seat hinged.
This hold-down mechanism adopts cylinder to compress locate mode, it comprises angle bearing and the clamping cylinder that is arranged on the bearing of angle, the angle bearing comprises base and support arm, support arm is provided with pressed seat, pressed seat is fixedlyed connected with support arm, the intersection of base and support arm is tiltedly installed with the clamping cylinder, clamping the installation bottom surface of cylinder and the upper surface of base intersects in obtuse angle, be connected with the joint connecting rod on the motion bar of clamping cylinder, the other end of joint connecting rod is fixed with pressure strip, and pressure strip is simultaneously also hinged with pressed seat; It adopts lever principle that workpiece is compressed, when clamping the cylinder ventilation, the motion bar that clamps cylinder is perpendicular to the make progress hinged end of top pressure strip of bottom surface is installed, and pressure strip is simultaneously also hinged with pressed seat, then the hinged free position, top of pressure strip and pressed seat will be movable downwards around the hinged place, when reaching, the motion bar that clamps cylinder to a certain degree will make pressure strip workpiece pressing inflexibly, guarantee compressing and locating of workpiece, it has saved employee's man-hour, reduce employee's workload, improved welding production efficiency.
As preferably, the motion bar that clamps cylinder is fixedlyed connected with the joint connecting rod, and it is hinged that an end of the other end of joint connecting rod and pressure strip passes through bearing pin.The motion bar that clamps cylinder is fixedlyed connected with an end of joint connector, one end of the other end of joint connector and pressure strip is hinged, make it better meet lever principle, when clamping the cylinder ventilation, the motion bar that clamps cylinder is perpendicular to the make progress hinged end of top pressure strip of bottom surface is installed, and the free end of pressure strip will move downward around the hinged bearing pin of pressure strip and pressed seat, makes its workpiece pressing.
As preferably, an end of described pressed seat and support arm are by bolting, and it is hinged that bearing pin is passed through at the other end of pressed seat and the middle part of pressure strip.
As preferably, the other end of described pressure strip is provided with locating hole.The other end of described pressing plate is provided with locating hole, and this locating hole is used for guaranteeing the stud welding accuracy in the position that positioning stud welds.
The utility model compared with prior art has following beneficial effect: by changing the location compressing structure of anchor clamps, make it compress to be converted to from outer workpiece and compress from workpiece inside, realize vertically to take, put workpiece before and after the welding, saved employee's man-hour, reduce personnel labor, improved the operating efficiency of welding.
