Description
Technical field
The present invention relates to a kind of clamping tool.
Background technology
At present, the welding of Bus Frame commonly used robotic welding technology.Because seat channel-section steel is typically using thickness
Plate roller system, is limited by processing technology, and the channel-section steel processed often has problems with：（1）The contour accuracy of part is difficult to ensure that,
The width dimensions b of particularly channel-section steel is difficult to ensure that, as shown in Figure 1；（2）Homogeneity of product is bad.
However, when being welded using robotic welding technology to Bus Frame, it is desirable to which welded part meets more accurate
Positioning precision, but the presence of above mentioned problem causes very big difficulty to the design and use of weld jig, if using existing
Fixture, one in two chucks on fixture is fixed to be set, and another can lead to relative to the clamping head being fixedly installed
Overregulating bolt rotates it；When fixture is in and clamps position, on the premise of the overall size of chuck is constant, between two chucks
The size for the workpiece that can be clamped is fixed, for the poor workpiece of some contour accuracies, existing clamp system not only without
Method meets the clamping demand of same channel-section steel diverse location, can not also meet the clamping demand of different channel-section steels, therefore, it is difficult to realize
Weld clamp has had a strong impact on the welding efficiency of Bus Frame, it is necessary to be adjusted repeatedly to fixture.
The content of the invention
It is an object of the invention to provide a kind of clamping tool, to solve during existing clamp workpiece operating efficiency compared with
Low the problem of.
To achieve the above object, a kind of technical scheme of clamping tool of the invention is：

Also include double leval jib hold-down mechanism, double leval jib hold-down mechanism has a pressure head, the compaction direction of pressure head is towards support base
Supporting surface.
The pressure head is adjustably arranged in pressure head mounting seat along its compaction direction position.
Pressure head is formed by the head of hold-down bolt, and the bar portion of hold-down bolt is located in the screwed hole in pressure head mounting seat
Interior, hold-down bolt is provided with stop nut in the both sides of screwed hole.
The beneficial effects of the invention are as follows：Elastic compression unit is equipped with two chucks in frock of the present invention, this is used
When frock is to Workpiece clamping, the elastic deformation of flexible member can inhale the error of the contour accuracy of compensation workpiece, while clamping
Also the centering of workpiece can be realized, compared to prior art, the time for changing frock is saved, can preferably clamp workpiece,
Improve the efficiency of work.
Further, in addition to double leval jib hold-down mechanism and the pressure head mounting seat that is arranged on hold-down mechanism, pressure head mounting seat
Upper that pressure head is housed, the work that pressure head is compressed can drive the action that two L-shaped connecting levers are clamped to the rotation in the direction for clamping workpiece, one
Individual action is realized to being fixedly clamped in workpiece in both directions.
Further, in addition to the adjust pad that is arranged between workpiece and base, on the one hand can by the adjust pad
On the other hand the clamped workpiece of regulation can also be realized to two L-shaped relative to the relative position with the workpiece of the work pieces mate
Regulation of the connecting lever to the clamping force of workpiece.
Further, the pressure head and pressure head mounting seat, realize adjustable connection by helicitic texture, enable frock of the present invention
Enough it is applied to the workpiece of more different-thickness.
Brief description of the drawings
