Abstract
The utility model relates to a clamping device for a symmetrical elbow arm. The clamping device for the symmetrical elbow arm comprises clamping sliding boards which are respectively and movably arranged at the both sides of the elbow arm, wherein a clamping base is arranged on each clamping sliding board; a clamping cylinder is arranged on the elbow arm; a linking block is arranged on the movable rod of the clamping cylinder; two synchronizing bars are movably arranged on the linking block; one end of each of the two synchronizing bars is movably connected with the linking block; and the other end of each synchronizing bar is movably connected with the corresponding clamping sliding board. The clamping device for the symmetrical elbow arm provided by the utility model is applicable to an elbow machine capable of bending a tubular piece leftward and rightward. By adopting the clamping device for the symmetrical elbow arm, the entire structural size of the elbow arm is reduced to a half of the former elbow arm, so that the weight is greatly reduced, the inertia is correspondingly reduced in a tube bending process, and the speed of bending a tube is improved; and furthermore, the clamping device for the symmetrical elbow arm is driven by a single driving source when being compared with the former two driving sources, and has the advantages of simple structure and smaller size. Moreover, the cost is lower, and the quantity of control points and detecting points further can be reduced through a corresponding control program.
Description
Technical field
The utility model relates to the technical field of bending machine, refers to especially a kind of clamping device of symmetrical bending pipe arm.
Background technology
In carrying out the curved bending machine in left and right to pipe fitting, it need to clamp respectively two positions of pipe fitting.By adopting two covers to clamp device, be separately positioned on the both sides of bending pipe arm in the bending machine that uses at present, it is complex structure, bulky not only, and needs to adopt two drivings, and cost is higher.
The utility model content
Technical problem to be solved in the utility model is: the clamping device that a kind of simple in structure, small volume, lower-cost symmetrical bending pipe arm are provided.
For addressing the above problem, the technical solution adopted in the utility model is: the clamping device of symmetrical bending pipe arm, comprise the clamping slide plate that is movably arranged on respectively the bending pipe arm both sides, each clamps on slide plate and is provided with clamping seats, be provided with a clamping cylinder on bending pipe arm, be provided with coupling block on the motion bar of clamping cylinder, be movably set with two synchronizing bars on coupling block, one end of two synchronizing bars all is flexibly connected mutually with coupling block, and the other end of each synchronizing bar is flexibly connected mutually with corresponding clamping slide plate.
Each front and back end that clamps slide plate is respectively arranged with front rod and back link, and front rod and back link are arranged in parallel, and an end of front rod and back link is flexibly connected mutually with clamping slide plate, and the other end of front rod and back link and bending pipe arm are flexibly connected.
Described clamping seats is movably arranged on and clamps on slide plate, clamps on slide plate and is provided with adjustment seat, is provided with adjustment screw in adjustment seat, and the end of adjustment screw contacts with clamping seats.
The beneficial effects of the utility model are: after adopting the clamping device of above-mentioned symmetrical bending pipe arm, it is original 1/2nd that the overall structure size of bending pipe arm is reduced into, and weight alleviates greatly, and the inertia during bend pipe is corresponding to be reduced, and bend pipe speed is improved; And the clamping device of above-mentioned symmetrical bending pipe arm, become single driving by two original drivings, its simple in structure, small volume, and also cost is lower, and corresponding control program also reduces control point and test point.

Fig. 2 is the structural representation that the utility model is in clamped condition;
In figure: 1, bending pipe arm, 2, clamp slide plate, 3, clamping seats, 4, clamping cylinder, 5, coupling block, 6, synchronizing bar, 7, front rod, 8, back link, 9, adjustment seat, 10, adjustment screw.
The specific embodiment
Be described in further detail below by the clamping device of specific embodiment to the symmetrical bending pipe arm of the utility model.
As shown in Figure 1, the clamping device of symmetrical bending pipe arm, comprise the clamping slide plate 2 that is movably arranged on respectively bending pipe arm 1 both sides, each clamps on slide plate 2 and is provided with clamping seats 3, be provided with a clamping cylinder 4 on bending pipe arm 1, clamping cylinder 4 can make cylinder also can make oil cylinder or other driver parts, be provided with coupling block 5 on the motion bar of clamping cylinder 4, be movably set with two synchronizing bars 6 on coupling block 5, one end of two synchronizing bars 6 all is flexibly connected mutually with coupling block 5, and the other end of each synchronizing bar 6 is flexibly connected mutually with corresponding clamping slide plate 2.
As preferred version, each front and back end that clamps slide plate 2 is respectively arranged with front rod 7 and back link 8, front rod 7 and back link 8 are arranged in parallel, and an end of front rod 7 and back link 8 is flexibly connected mutually with clamping slide plate 2, and the other end of front rod 7 and back link 8 and bending pipe arm 1 are flexibly connected.By the setting of front rod 7 and back link 8, when clamping slide plate 2 slided on bending pipe arm 1, front rod 7, back link 8 and clamping slide plate 2 formed a parallel-crank mechanism, move more reliable and more stable.
As preferred version, described clamping seats 3 is movably arranged on and clamps on slide plate 2, clamps on slide plate 2 and is provided with adjustment seat 9, is provided with adjustment screw 10 in adjustment seat 9, and the end of adjustment screw 10 contacts with clamping seats 3.When also having less gap between pipe fitting and clamping seats 3, can pass through degree of tightness adjustment screw 10, realize the purpose of fine setting clamping seats 3 front and back positions, thereby make clamping more firm.
As shown in Figure 1, the clamping device of above-mentioned symmetrical bending pipe arm 1 is in the folder state that moves back, during work, motion bar by clamping cylinder 4 stretches out, drive two synchronizing bars 6 by coupling block 5 and move forward, thereby drive two clamp slide plates 2 on bending pipe arm 1 synchronously to front slide, when clamping slide plate 2 slip, front rod 7 and back link 8 synchronously swing, and then drive clamping seats 3 and move forward the clamping pipe fitting, and its state as shown in Figure 2.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
