Abstract
The utility model discloses a combined clamp capable of performing translation and clamping. The combined clamp comprises a machine frame, an extensible hydraulic cylinder provided with an extensible rod, a rocker, a connection rod, a clamp head with a hook portion arranged at the front end, a linear guide groove and a combined guide groove. One end of the rocker is hinged to the front end of the extensible rod, the other end of the rocker is hinged to the machine frame, and the extensible rod extends and contacts to drive the rocker to swing. The combined guiding groove comprises a linear section parallel to the linear guiding groove and an arc section with the tail end of the front side of the linear guiding groove as the circle center, and two guiding shafts respectively installed on the linear guiding groove and the combined guiding groove in sliding guiding mode are arranged at the rear end of the clamp head. Two ends of the connection rod are respectively hinged to the rocker and the clamp head, and through driving of rotation of the rocker, the connection rod can push the clamp head to translate forwards along the linear guiding groove and the linear section of the combined guiding groove to extend out, and then the clamp head rotate along the arc section of the combined guiding groove with the tail end of the front side of the linear guiding groove as the circle center, so that clamping is achieved. The combined clamp is small in occupation and strong in shape adaptability and facilitates positioning and clamping.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind of combined fixture that has translation, clamps action.
Background technology
On the welding together equipment of large-scale framework, for example passenger vehicle attaches together tire, mostly adopt automatic clamping mechanism, to improve positioning accuracy and welding quality, yet existing automatic clamping mechanism volume and the radius of gyration are larger, add that the form that attaches together the tire skeleton is changeable, clamp required space and be severely limited, be not easy to positioning and clamping and welding operation.
The utility model content
The purpose of this utility model is to provide the translation that a kind of space hold is few, Morphological adaptability is strong, the combined fixture of clamping action for above problem.
In order to realize above purpose, the technical scheme that the utility model adopts is: translation, clamp the combined fixture of action, described anchor clamps comprise frame, be located at drive unit on the frame, be hinged on rocking bar on the frame, be opened in line channel and compound guide groove on the frame; Described drive unit comprises the rotation section that is hinged on the frame and can radially export along the rotation of rotation section the expansion link of linear telescopic action; Described rocking bar rear end is hinged on the frame, the front end of front end and described expansion link is hinged and at the flexible lower swing that drives of expansion link; Described line channel is extended by backward forward position straight line, and compound guide groove comprises straightway and the arc section take the line channel front end as the center of circle that be arranged in parallel with line channel; Described anchor clamps comprise that also front end is provided with the chuck of hook portion, described collet rear be provided with two respectively slide-and-guide be assemblied in the axis of guide in line channel and the compound guide groove; Be hinged with connecting rod between described collet rear and the rocking bar, described connecting rod, chuck and rocking bar consist of the slider-crank mechanism take rocking bar as input; When clamp, described chuck under the wobbling action of rocking bar forward input drives first along the straightway of line channel and compound guide groove forward translation stretch out, rotate the rotation that realize chuck as the center of circle along the arc section of compound guide groove take the line channel front end again and clamp and move; When anchor clamps discharge, described chuck rocking bar under oppositely the wobbling action of input drives first take the line channel front end as the center of circle arc section backward rotation along compound guide groove, again along the straightway of line channel and compound guide groove backward translation regain and realize the release movement of chuck.
The crank block structure and the drive unit that adopt two guide grooves, corresponding chuck, rocking bar, connecting rod to consist of, chuck just can stretch out clamp body when needs clamp, and its radius of gyration is little, thereby occupies little space, changeable matrix morphology be can adapt to, clamping location and weld job are convenient to.Described rocking bar and connecting rod can make when clamping rocking bar and connecting rod approach or are in the dead-centre position by the long and pin joint position of bar suitably is set, and reach the clamping effect of needs.The drive unit that can satisfy above-mentioned functions can adopt telescopic hydraulic cylinder, pneumatic cylinder or other similar means, is convenient to adopt automation control, and enough clamping forces are provided.
The pin joint of described connecting rod and rocking bar can utilize lever principle to the larger active force of connecting rod input between the pin joint of rocking bar and frame and expansion link like this, and is convenient to the adjustment optimization of articulated position.
Description of drawings
The utility model is described in further detail below in conjunction with the specific embodiment accompanying drawing.
Structural representation when Fig. 1 is the utility model translation, the combined fixture initial position that clamps action;
Fig. 2 is the schematic diagram of chuck translation when stretching out;
Schematic diagram when Fig. 3 is chuck rotation clamping.
Each Reference numeral name is called among the figure: 1 frame, 2 chucks, 3 line channels, 4 compound guide grooves, 5 axis of guides, 6 rocking bars, 7 connecting rods, 8 telescopic hydraulic cylinders, 9 workpiece.
The specific embodiment
A kind of translation of the utility model, the embodiment of combined fixture that clamps action such as Fig. 1 ~ shown in Figure 3 comprise frame 1, are located on the frame 1 telescopic hydraulic cylinder 8 as drive unit, are hinged on rocking bar 6 on the frame 1, are opened in line channel 3 and compound guide groove 4 on the frame; Described telescopic hydraulic cylinder 8 comprises the rotation section that is hinged on the frame 1 and can radially export along the rotation of rotation section the expansion link of linear telescopic action; Described rocking bar 6 rear ends are hinged on the frame 1, the front end of front end and described expansion link is hinged and at the flexible lower swing that drives of expansion link; Described line channel 3 is extended by backward forward position straight line, and compound guide groove 4 comprises straightway and the arc section take line channel 3 front ends as the center of circle that be arranged in parallel with line channel 3; Described anchor clamps comprise that also front end is provided with the chuck 2 of hook portion, described chuck 2 rear portions be provided with two respectively slide-and-guide be assemblied in the axis of guide 5 in line channel 3 and the compound guide groove 4; Be hinged with connecting rod 7 between described chuck 2 rear portions and the rocking bar 6, the slider-crank mechanism that described connecting rod 7, chuck 2 and rocking bar 6 consist of take rocking bar 6 as input; When clamp, described chuck 2 under the wobbling action of rocking bar 6 forwards inputs drives first along the straightway of line channel 3 and compound guide groove 4 forward translation stretch out, rotate the rotation that realize chuck 2 as the center of circle along the arc section of compound guide groove 4 take line channel 3 front ends again and clamp and move; When anchor clamps discharge, described chuck 2 rocking bar 6 under oppositely the wobbling actions of input drive first take line channel 3 front ends as the center of circle arc section backward rotation along compound guide groove 4, again along the straightway of line channel 3 and compound guide groove 4 backward translation regain and realize the release movement of chuck 2.
