The centering mechanism is simple in overall structure and capable of bearing large transmission force, and centering is carried out easily and accurately with small errors.
Description
Technical field
The present invention relates to a kind of centering body, the centering for machined to workpiece, so that the position of clamping workpiece is accurate.
Background technology
Workpiece needs workpiece to be transported to frock position before machined, then by clamping mechanism, is fixed, and in the time of fixedly, the precision of centering is extremely important, have influence on the machining accuracy of workpiece, the centering body of workpiece mostly is bar linkage structure, complicated integral structure at present, take up room large, holding capacity is less.
Summary of the invention
The object of this invention is to provide that a kind of overall structure is simple, flexible movements are reliable, error is little, can bear the centering body of larger driving force, overcome the deficiencies in the prior art.
Centering body of the present invention, comprise framework, on framework, being provided with can axially movable rack shaft, the termination of rack shaft and piston rod joins, oil cylinder is fixedly connected on framework, on framework, by rotating shaft, be connected with the first relative swing arm and the second swing arm, the termination of the first swing arm and the second swing arm is all connected with pressure head, at the other end of the first swing arm, be processed with the tooth being meshed with tooth bar on described rack shaft, on framework, by rotating shaft, the transition gear being meshed with tooth bar on described rack shaft is installed, the other end of the second swing arm is processed with the tooth being meshed with described transition gear, between described rack shaft and framework, be provided with guide pin bushing.
The rear end of described oil cylinder is provided with link and approach switch is installed, and the piston rod matching with oil cylinder stretches out from oil cylinder rear end and matches with described approach switch.
Described piston rod is connected to connecting axle, described rack shaft comprises the second rack shaft with connecting axle phase, the second rack shaft joins by connector and the first rack shaft, described guide pin bushing comprises the first guide pin bushing and the second guide pin bushing, the first guide pin bushing is between the first rack shaft and framework, and the second guide pin bushing is between the second rack shaft and framework.
Between described pressure head and swing arm, be provided with adjusting pad.
Centering body of the present invention, frock clamp mechanism by frame installation at workpiece locates, when workpiece is transported to herein, first by cylinder action, rack shaft moves, there is relative swing with the second swing arm in the first swing arm, termination relies on workpiece, i.e. holding workpiece relatively, make workpiece that horizontal displacement occur, reach the object of centering, the position of workpiece centering can change the thickness of adjusting pad while needing trace to adjust determines, the length that can change connector while adjusting is in a large number determined.Overall structure is simple, and centering is easy, and precisely, error is little, can bear larger driving force.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment
As shown in Figure 1: 4 is framework, on framework 4, being provided with can axially movable rack shaft, and rack shaft comprises with the second rack shaft 8, the second rack shafts 8 of connecting axle 16 phases and joining by connector 7 and the first rack shaft 5.Between each rack shaft and framework 4, be provided with guide pin bushing, guide pin bushing comprises that the first guide pin bushing 6 and the second guide pin bushing 11, the first guide pin bushings 6 are between the first rack shaft 5 and framework 4, and the second guide pin bushing 11 is between the second rack shaft 8 and framework 4.Connecting axle 16 joins with the termination of piston rod 12, and the oil cylinder 10 that piston rod 12 matches is fixedly connected on framework 4 and with hydraulic control device and joins.Each above-mentioned rack shaft is on axle, to be processed with part tooth bar, and the opening of section of rack on framework 4 exposes, so that mesh with other parts.
On framework 4, by rotating shaft, be connected with the first relative swing arm 3 and the second swing arm 14.The termination of the first swing arm 3 and the second swing arm 14 is all connected with pressure head 2, and on the inner termination of pressure head 2 and the workpiece of clamping 15, the shape of relevant position matches.At the other end of the first swing arm 3, be processed with the tooth being meshed with tooth bar on the first rack shaft 5.The other end that by rotating shaft transition gear 9, the second swing arms 14 that are meshed with tooth bar on the second rack shaft 8 is installed on framework 4 is processed with the tooth being meshed with transition gear 9,
The rear end of oil cylinder 10 is provided with link and approach switch 13 is installed, and the piston rod matching with oil cylinder 10 stretches out from oil cylinder rear end and matches with approach switch 13, and approach switch 13 joins with control device, for the control to piston rod displacement.
Between pressure head 2 and swing arm, be provided with adjusting pad 1.
Centering body of the present invention, the frock clamp mechanism that is arranged on workpiece by framework 4 locates, when workpiece 15 is transported to herein, first by oil cylinder 10, moved, rack shaft moves, there is relative swing with the second swing arm in the first swing arm 3, be that termination band dynamic head 2 relies on workpiece relatively, it is holding workpiece 15, make workpiece 15 that horizontal displacement occur, reach the object of centering, the position of workpiece centering can change the thickness of adjusting pad 1 while needing trace to adjust determines, the length that can change connector 7 while adjusting is in a large number determined.Overall structure is simple, and centering is easy, and precisely, error is little, can bear larger driving force.
