the board process equipment in current machined field (such as cut, welding etc.) is all high precision electric control equipment, and the lifting mechanism wherein for lifting heavy or other functional supports all adopts electric threaded shaft mechanism usually.The formation of electric threaded shaft mechanism comprises motor, screw mandrel, framework, nut movable block usually, motor is fixed on and framework connects and drives screw mandrel to rotate, nut movable block is slidedly arranged on framework, and coordinate with wire rod thread, the usual of bearing plate or other functional supports and so on for lifting heavy is all fixed on nut movable block.As everyone knows, electric threaded shaft has higher control and running precision.
but the existing above-mentioned electric threaded shaft mechanism applied on board process equipment there are the following problems:
nut movable block is mainly using screw mandrel as the support supported, when nut movable block is stressed, its shearing force be applied on screw mandrel is comparatively large, causes the snap-in force between screw mandrel to increase, increase frictional resistance between the two, affect the driving smoothness of screw mandrel for nut movable block.And through using for a long time, for nut movable block and screw mandrel loss comparatively large, not only affect quality of fit and job stability, and easily produces noise, greatly the service life of reducing mechanism, the maintenance of increase mechanism and maintenance cost.
Summary of the invention
the utility model object is: for the deficiency of known electric threaded shaft mechanism, and provide a kind of smooth running, precision high, and the stability lifting mechanism of long service life.
the technical solution of the utility model is: a kind of high stability lifting mechanism, comprise motor, screw mandrel, framework, nut movable block, described screw mandrel is longitudinally arranged, described motor is fixed on and framework connects and drives described screw mandrel to rotate, described nut movable block coordinates with wire rod thread, characterized by further comprising support guide mechanism, this mechanism comprises the guiding trolley fixing with nut movable block, and to be fixed in described framework and the guide plate be arranged in parallel with described screw mandrel, described guiding trolley is provided with two row's rollers of the described guide plate of clamping.
further, framework described in the utility model is also provided with the support plate parallel with guide plate, wherein arranging roller and offset of this support plate and described guiding trolley.
further, guide plate described in the utility model is between guiding trolley and support plate.
preferably, guide plate described in the utility model and support plate are connected and fixed by securing member.Securing member can be screw, bolt or latch.
further, described in the utility model, base of frame is integrally formed with adpting flange.Effect is fixed by screw or bolt and board.
further, framework described in the utility model is provided with for the up and down longitudinal grooved of screw thread movable block, and described screw thread movable block is arranged in this longitudinal grooved.
further, described in the utility model, motor is fixed on frame roof.
further, motor described in the utility model is be equipped with the common three phase electric machine of corresponding reductor, stepper motor or servomotor.
this high stability lifting mechanism that the utility model provides is a component of board process equipment, board process equipment attribute according to reality (such as welds, or cutting, or positioning tool), determine on its nut movable block it is fixing bearing plate, or the lifting transverse arm etc. of welding or cutting head.
the utility model has the advantages that:
1. the utility model is because having installed support guide mechanism additional, share nut movable block by guide plate and framework and be originally applied to shearing force on screw mandrel, alleviate the snap-in force between nut movable block and screw mandrel, greatly reduce both frictional resistance, make screw mandrel run more smooth and easy for the driving of nut movable block.Decrease the wearing and tearing for parts in long-term use simultaneously, be conducive to improving nut movable block and the quality of fit of screw mandrel and the job stability of whole mechanism.
2. the utility model has longer service life, can save maintenance cost.
3. alleviate the friction between nut movable block and screw mandrel by support guide mechanism in the utility model, add that dolly is by roller and guide plate Structure deformation, smooth when nut movable block is run up and down, greatly reduces noise during real work.
