Description
Technical field
The utility model relates to manufacturing frock clamp field, particularly a kind of secondary axial turning fixture.
Background technology
In manufacturing, especially welded body technical field, weld jig has vital effect to the precision of controlling vehicle body.
In order to reduce the complexity of project cost and fixture, general fixture is all designed to fix.But due to the restriction of product structure and operating position, stationary fixture differs and realizes surely good operability.For example longeron assembly station, Y-direction and Z-direction all have solder joint, and likely Z-direction bottom surface also needs CO
2welding, if use fixing fixture, employee's operation posture is more strange, does not meet human engineering; And along with the development of solder technology, intermediate frequency integrated soldering turret is applied also further extensively, though intermediate frequency integrated soldering turret can provide good welding quality, itself result and size are heavier, therefore, operative employee cannot realize by rotation soldering turret the welding operation of multi-angle.For similar situation, generally need by jig Design become axial turnover mechanism while planning early stage.
Because compressed air is a kind of cheap, easy preservation, safety and the power source that easily obtains, cylinder utilizes this power source to come transferring energy and signal just, and therefore, in jig Design now, cylinder is more and more widely used as executive component.At present, apply to such an extent that the axial turning fixture that is welded comparatively widely has following two kinds:
One, as shown in Figure 1, cylinder directly drives fixture upset by rack pinion, and this kind of mechanism principle is simple, and price is lower, and mechanism stable is widely used.But the executive component of Ci Zhong mechanism is cylinder, cylinder only has two kinds of motion states, and stretching to put in place and retreat puts in place, and therefore the axial turnover mechanism of this kind of structure can only be realized once rotation, therefore be only applicable to need the workpiece location of two kinds of operation postures, have certain limitation.
Two, driven by servomotor, drives fixture upset by rack-and-pinion or other mechanisms.The executive component of Ci Zhong mechanism is motor, therefore can realize the axial turning of multi-angle, but the relative cylinder of the cost of motor is high, and is only applicable to automatically controlled fixture.
Summary of the invention
The purpose of this utility model is to propose a kind of novel secondary axial turning fixture, and this turnover fixture can utilize cylinder as power source, realizes the upset of multi-angle, to adapt to the welding of operation plate of multi-angle.
Secondary axial turning fixture of the present utility model comprises holder, the first cylinder, the second cylinder, and described holder is movably installed with trip shaft by clutch shaft bearing, and the end of described trip shaft is fixedly connected with a connecting plate for stationary fixture; Cylinder body bottom and the holder of described the first cylinder are hinged, and the piston rod of the first cylinder and a push rod are hinged; The cylinder body of described the second cylinder and the end of described push rod are hinged, and the other end of described push rod is flexibly connected with described trip shaft by the second bearing; The piston rod of described the second cylinder is connected with a fixed axis by the 3rd bearing, and the end of described fixed axis is fixedly connected with described connecting plate.
In use, first make the piston rod of the first cylinder and the second cylinder all in retracted state, now connecting plate and on fixture in the first angle, after operation under this angle completes, the piston rod of the first cylinder is stretched out, drive push rod, the second cylinder rotates around trip shaft, because the piston rod position of the second cylinder does not become, therefore the relative position of the second cylinder and connecting plate is also just constant, connecting plate and on fixture can forward the second angle to along with the rotation of the second cylinder, under the second angle operation complete after, keep the piston rod of the first cylinder in stretching out state, the piston rod of simultaneously controlling the second cylinder stretches out, the piston rod of the second cylinder drives connecting plate to rotate around trip shaft by fixed axis, make connecting plate and on fixture turn to the 3rd angle, realize secondary axial turning, for operation provides three angles.The piston rod of the first cylinder, the second cylinder is regained, can make connecting plate and on fixture return to initial angle.
For increasing moment, the piston rod of described the first cylinder and the medium position of described push rod are hinged.
For convenience of mobile, the base of described holder is provided with roller.
For easy for installation and fixing firm, the end of described trip shaft is fixedly connected with connecting plate by flange; The end of described fixed axis is fixedly connected with connecting plate by flange.
Can not only the satisfy the demand welding of multi-angle operation plate of above-mentioned secondary axial turning fixture, and according to different operation postures, can be by selecting the first cylinder and/or second cylinder of different strokes, set voluntarily each axial turning angle, owing to having adopted cylinder as power source, cost is lower, reliable operation, life-span is long, compact conformation, easy care maintenance.
