A hydraulic motor is fixed to a movable bracket, the movable bracket is connected with the bracket through a check ring in a sliding mode, the hydraulic motor is connected with a lead screw through a combiner, the lead screw is rotationally connected with a nut, the nut and the cutting board are connected together, a proximity switch is fixed to a Z-shaped support fixed to the bracket, a disc spring is connected with the interior of a concave hole in the bracket and is connected with a pin, and the outer end of the pin is connected with a pressing screw connected with the movable bracket. A traditional manual moving mode of the cutting board is changed, so that cutting board moves to take part in numerical control feed, the tool setting frequency of a transverse shaft is reduced, and the hierarchical positioning mechanism for the cutting board is easy to operate, low in fault rate and high in work efficiency.
Description
Technical field
The present invention relates to a kind of knife plate classification detent mechanism, belong to heavy mechanical equipment technical field.
Background technology
The movement of current known upper tool post knife plate is manual mobile form, motor removing form.And traditional manual mobile form, this formal operations efficiency is low, wastes time and energy, and the position of knife plate movement cannot accurately control, and makes knife plate participate in numerical control feeding.Motor removing form, between the reference point of knife plate moving direction and the reference point of knife rest transverse shifting, relative position can not accurately be located, and makes its positioning precision reach requirement.In International Sci & Tech Cooperation " 2011DFB71630 " project, for solving the problem of CNC heavy-duty horizontal lathe knife plate classification location, primary study has invented this mechanism.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of knife plate classification detent mechanism, change the deficiency of the traditional manual mobile form of knife plate and motor removing form, for machine tooling provides a kind of easy to operate, the knife plate that operating efficiency is high moves form.Knife plate is moved on upper slitter support body by leading screw, hydraulic jack is fixed on upper slitter support body, and control the insertion of positioning key and extract, hydraulic motor is fixed on bracket, driving leading screw to rotate makes knife plate locating slot contact completely with positioning key side, thus realizes the precision positioning of knife plate movement.
The technical solution adopted for the present invention to solve the technical problems is: knife plate classification detent mechanism, is made up of knife plate, upper slitter support body, hydraulic jack, screw mandrel, screw, bracket, disc spring, pin, zygote, hydraulic motor, mobile bracket, back-up ring, proximity switch, Z-shaped support, lower position switch, large support, upper limit position switch, small rack, limited block.Hydraulic jack, bracket are separately fixed on upper slitter support body.Lower position switch, large support, upper limit position switch, small rack, limited block are separately fixed on hydraulic jack successively, and the locating slot that the positioning key that hydraulic jack connects and knife plate are provided with is scalable to be connected.Hydraulic motor is fixed on movable support bracket, mobile bracket is slidably connected with bracket by back-up ring, hydraulic motor is connected with screw mandrel by zygote, screw mandrel is rotatably connected with screw, and together with screw puts together on knife plate, proximity switch is fixed on Z-shaped support, Z-shaped support is fixed on bracket, in the shrinkage pool that bracket is provided with, be connected with disc spring, disc spring is connected with pin, the outer end of pin connects with the screw that holds out against that mobile bracket is connected.
The course of work and operation principle: hydraulic motor drives screw mandrel to turn clockwise by zygote, after making knife plate be moved upwards up to position, positioning key in hydraulic jack inserts in the locating slot on knife plate, signal is sent by upper limit position switch after positioning key puts in place, hydraulic motor is rotated counterclockwise, knife plate moves down the positioning key contacts side surfaces in the side and hydraulic jack making locating slot, then hydraulic motor continues to be rotated counterclockwise, the screw that holds out against on movable support bracket is made to extrude pin, now disc spring is in by pressure condition, this process provides certain pressure by for two sides contact, knife plate is made to be in by pressure condition, when knife plate moves on to its anchor point place in advance, hydraulic motor drives screw mandrel to turn clockwise, movable support bracket is moved down, when movable support bracket touches proximity switch, hydraulic motor stops the rotation, and send signal, loop cycle is next time carried out in the position that now knife plate just can move to its anchor point.Knife plate is moved on upper slitter support body by leading screw, hydraulic jack is fixed on upper slitter support body, control the insertion of positioning key and extract, hydraulic motor is fixed on bracket, driving leading screw to rotate makes knife plate locating slot contact completely with positioning key side, the positioning precision of knife plate movement is ensured by the positional precision of locating slot on knife plate, as long as the positional precision between raising locating slot, the classification positioning precision of knife plate also can correspondingly be improved, and is realized the precision positioning of knife plate by the positional precision improving locating slot on knife plate.
The invention has the beneficial effects as follows: use this knife plate classification detent mechanism, the traditional manual changing knife plate moves form, making knife plate move participation numerical control feeding, reduce the tool setting number of times of transverse axis, is processing ease, failure rate is low, precision positioning mechanism that operating efficiency is high.Be suitable for heavy horizontal lathe knife plate location to use, be also applicable to heavy roller lathe and use.
