The multipoint clamping mechanism comprises a wallboard, a driving clamping force arm, one or more driven clamping force arms, one or more force transmission devices and a power output device, wherein a through hole is formed in the middle of the wallboard; the driving clamping force arm and the one or more driven clamping force arms are sequentially arranged at the periphery of the through hole in a surrounding mode; the driving clamping force arm or the driven clamping force arm is connected with a driving clamping force arm or a driven clamping force arm in the next sequence through the force transmission devices; the driving clamping force arm is provided with a strip-type stressed end; and the stressed end is connected with the power output device. By a rotation block expansion type multipoint clamping method, the device has a simple structure, can tightly clamp parts in a reducing mode and can automatically adapt to the sizes of pipes; and simultaneously, the pipes cannot be clamped and ejected without well adjustment of a lower clamping block, so that the production efficiency of the pipes is greatly improved.
Description
Technical field
The utility model relates to positioning clamping device, particularly a kind of cutting machine multiple spot clamping mechanism.
Background technology
At present, four pipes both domestic and external, the 63 two-tube rotations piece formula chipless cutting machine that rises all adopts cylinder clamping or guide pin bushing guiding dual mode to clamp cutting.But on-line velocity under the situation, because the cylinder clamping mode needs accurately to regulate fixture block up and down, but is being regulated under the inaccurate situation faster, and clamp is unstable, causes card to manage easily, thereby influences tubing outward appearance and quality thereof.And the mode of guide pin bushing guiding does not only clamp function, and in the first trombone slide stage, under the situation of tubing distortion, tubing has influenced production efficiency greatly through less than cutting machine.
The utility model content
The utility model provides a kind of cutting machine multiple spot clamping mechanism, and unstable to solve the clamp that prior art exists, tubing influences the technical problem of production efficiency through less than cutting machine.
The technical scheme that adopts is following:
A kind of cutting machine multiple spot clamping mechanism comprises wallboard, the main arm of force, one or more from clamping the arm of force, one or more force transfering device and PTO that clamps, and has through hole in the middle of the said wallboard; The main arm of force and one or more that clamps from clamping the arm of force successively in proper order around on the circumference that is arranged on through hole; The master clamps the arm of force or is connected through force transfering device with the main clamping arm of force of next order or from clamping the arm of force from clamping the arm of force, and the main arm of force that clamps is provided with main force's arm supporting axis, and main force's arm supporting axis is fixed on the wallboard; Main clamping force upper-arm circumference is around main force's arm supporting axis rotation; Also be provided with from arm of force supporting axis from clamping on the arm of force, be fixed on the wallboard from arm of force supporting axis, from the clamping force upper-arm circumference around rotating from arm of force supporting axis; The main clamping arm of force also is provided with the force side of strip, and the force side is connected with PTO.
Further, said force transfering device is a hinge.
Further, said PTO is that cylinder reaches the cylinder rod that links to each other with cylinder, and the main force side that clamps the arm of force is connected with cylinder through cylinder rod.
Further, include more than 3 or 3 from clamping the arm of force.
The utility model adopts the rotation piece formula multiple spot clamping method that rises, compact conformation, and reducing clamps, and can adapt to the tubing size automatically, solves down fixture block simultaneously and is regulating under the bad situation, does not block pipe, the phenomenon of push pipe not, improves the production efficiency of tubing greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model clamp mechanism in complete machine;
Fig. 2 is the structural representation of the utility model clamp mechanism.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed explanation.
When producing originally time or tubing when changing specification; Irregular deformation all can take place in initial pipeline, and it is all big than tubing to need to import and export specification this moment, adopts the multiple spot clamping mode in inactive state, just can reach this requirement among the present invention; Thereby avoid the card pipe, the situation of push pipe.
The utility model is a kind of cutting machine multiple spot clamping mechanism 1, and is specifically as shown in Figure 1, is arranged on before cutting machine 2 inlet pipes, is used to clamp tubing.
This clamp mechanism is specifically as shown in Figure 2, comprises that wallboard 3, the main arm of force 4, three of clamping from clamping the arm of force 5, four hinges 6, cylinder 7 and cylinder rods, have through holes in the middle of the wallboard 3; Main clamp the arm of force 4 and three from clamping the arm of force 5 around being arranged on the through hole circumference; Main clamp the arm of force 4 and adjacent being connected through the hinge from clamping the arm of force 5, adjacent two also are connected through the hinge from clamping the arm of force 5, and the main arm of force 4 that clamps is in turn connected to form loop with three from the clamping arm of force 5; The main arm of force 4 that clamps is provided with main force's arm supporting axis 8; Main force's arm supporting axis 8 is fixed on the wallboard 3, and the main arm of force 4 that clamps also is provided with from arm of force supporting axis 9 from clamping on the arm of force 5 around 8 rotations of main force's arm supporting axis; Be fixed on the wallboard 3 from arm of force supporting axis 9; From clamping the arm of force 5 around rotating from arm of force supporting axis 9, the main clamping arm of force 4 also is provided with the force side 41 of strip, and force side 41 is connected with cylinder 7 through cylinder rod.
Operation principle:
When getting into normal trombone slide state, when duct length reaches requiring of setting, cylinder 7 actions; Cylinder rod stretches out forward; Main clamp the arm of force 4 actions and clamps tubing, other drive down at hinge 6 and move simultaneously from clamping the arm of force 5, because of main force's arm back shaft 8 with all be fixed on the wallboard from arm of force supporting axis 9; Therefore the master clamps the arm of force 4 and can do turning effort from clamping 5 of the arm of forces, reaches the effect of clamping pipe.Also because this mode has the clamping mode of four point locations rotations, so power is also average relatively, thereby better protect tubing, can clamping force inhomogeneous and weighing wounded damaged tubing by pressure.
