Abstract
The utility model discloses a novel centering clamping mechanism which comprises a frame; a slide rail is arranged on the frame; an upper clamping sliding block and a lower clamping sliding block are installed on the slide rail; rotating wheels are arranged at two ends of the slide rail; two transmission belts with equal length are installed on the two rotating wheels; the head and the tail of each transmission belt are respectively connected with the upper clamping sliding block and the lower clamping sliding block; and the upper clamping sliding block and the lower clamping sliding block move in opposite directions under the action of the transmission belts driven by a driving unit. The centering clamping mechanism has the advantages of simple and compact structure, few parts and low production and maintenance costs; the position of the clamped central plane is always kept unchanged during the moving (in a clamping manner) process of the upper clamping sliding block and the lower clamping sliding block, so that the centering clamping mechanism is stable in working and high in repeatability precision; the frame is only required to move up and down for adjusting the clamped central plane, no clamping force is transferred outside the frame, and the adjustment is convenient; and in addition, when a plurality of centering clamping mechanisms are used in a combined manner, after the clamped central planes of each group of the centering clamping mechanisms are adjusted to be consistent, the large and long components can be clamped in a centering manner, and the operation is convenient.
Description
Technical field:
The utility model relates to the centering clamp mechanism of using in a kind of plant equipment.
Background technology:
The centering clamp mechanism that existing machinery equipment is commonly used mainly contains following several: (1) utilize positive and reverse return to screw mandrel and nut moving linearly, characteristic that direction is opposite, cooperate the centering clamp mechanism of centering clamping work pieces; (2) the centering clamp mechanism of the intersection lever clamping work pieces of the shared fulcrum of application; (3) utilize the both sides motor to drag the centering clamp mechanism of clamping part clamping work pieces in opposite directions.More than several centering clamp mechanism its technical advantage and application are respectively arranged, but difference is separately arranged also, such as the manufacturing cost height, adjust inconvenience, clamp the median plane position and can't guarantee that hi-Fix clamps.
The utility model content:
The purpose of this utility model is the weak point that exists at prior art and a kind of novel centering clamp mechanism is provided, and it has reasonable in design, simple and compact for structure, working stability, characteristics easy to adjust.
For achieving the above object, novel centering clamp mechanism of the present utility model has a frame, frame is provided with slide rail, grip slide and following grip slide are installed on the slide rail, the two ends of slide rail are provided with runner, two isometric driving-belts are installed on the runner, and the head and the tail of driving-belt connect with last grip slide and following grip slide respectively; Last grip slide and following grip slide are made move toward one another by the driving of driver element under the drive of driving-belt.
Preferred as technique scheme, described driver element be the linear drives unit that connects with last grip slide or time grip slide.
Preferred as technique scheme, described driver element is the torque drive unit that connects with the rotating shaft of runner.
Preferred as technique scheme, described driving-belt can be born the bushroller chain of pulling force, band, flexible steel wire or steel band synchronously when crooked simultaneously.
Preferred as technique scheme, described slide rail is made up of retaining rail and slide block, for having only the assembly of a linear degrees of freedom.
The beneficial effects of the utility model are: it is simple and compact for structure, parts are few, production and maintenance cost are low; Last grip slide and following grip slide clamping median plane position in clamping moving process remains constant, working stability, repeatable accuracy height; Its adjustment that clamps median plane only need move up and down frame and get final product, and does not transmit clamping force outside the frame, adjusts very convenient; In addition, the utility model is a plurality of when being used in combination, after the clamping median plane of every group of centering clamp mechanism is adjusted into unanimity, but each centering clamp mechanism synchronization action, also action successively successively clamps big and long member for centering and has greater advantage.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the structural representation of the utility model embodiment two.
The specific embodiment:
Therefore the following stated only for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model.
See embodiment illustrated in figures 1 and 2: novel centering clamp mechanism of the present utility model has a frame 10, frame 10 is provided with slide rail 20, slide rail 20 is made up of retaining rail and slide block, be by machined and the assembly that has only a linear degrees of freedom that is assembled, as ball or roller line sliding-rail sliding mechanism.Grip slide 31 and following grip slide 32 are installed on the slide rail 20, the two ends of slide rail 20 are provided with runner 41 and runner 42, two isometric driving-belts 50 are installed on the runner 41 and 42, driving-belt 50 can bear the bushroller chain of pulling force, synchronous band, flexible steel wire or steel band etc. simultaneously when being crooked, in the present embodiment, driving-belt adopts bushroller chain; The head and the tail of driving-belt 50 connect with last grip slide 31 and following grip slide 32 respectively; Last grip slide 31 and following grip slide 32 are made move toward one another by the driving of driver element 60 under the drive of driving-belt 50.In the present embodiment, driver element 60 is the linear drives unit that links with following grip slide 32, and the linear drives unit has the function of straight line thrust output, as mechanisms such as oil cylinder, electric cylinder, Electrohydraulic push rod, cylinder, gas-liquid combination cylinders.
When grip slide 32 moves and clamps under driver element 60 drives, last grip slide 31 is made move toward one another by the drive of driving-belt 50, clamp the clamping median plane position that remains two grip slides in the moving process and remain unchanged, final clamping work pieces also makes the clamping point median plane of workpiece overlap with clamping median plane 100.
In embodiment shown in Figure 3 two, driver element 60 is the torque drive unit, has the mechanism of moment of torsion output or transmission moment of torsion such as reducing motor, sprocket wheel, gear, belt wheel, hydraulic motor etc.The output revolving shaft of torque drive unit connects by one of them rotating shaft of frame for movement and two runners 20, torque drive unit transmission of torque is to runner 20, runner 20 drives driving-belt 50 revolutions, driving-belt 50 drags grip slide 31 and following grip slide 32 slides into clamping work pieces, last grip slide 31 and following grip slide 32 clamp the clamping median plane position that remains two grip slides in the moving process and remain unchanged, and final clamping work pieces also makes the clamping point median plane of workpiece overlap with clamping median plane 100.
