Description
Technical field
The present invention relates to a kind of in milling machine the micro-adjusting mechanism of cutter, the concrete micron order tool rest governor motion that relates to high accuracy of adjustment.
Background technology
General band base series products seldom has micro-adjusting mechanism, and stroke is big when carrying out the trace adjustment, brings very big inconvenience to work.Adopt thread mechanism to rotatablely move to convert into mobile; Have accurately, steadily, reliable characteristics, so in the equipment such as plant equipment, often use thread mechanism to realize the displacement of parts; But, the only suitable displacement of realizing mesoscale of common screw thread gearshift.Too small displacement; Because the pitch of screw thread receives technology, that can not do is too little, when the screw rod nominal diameter is not less than 1 millimeter; Pitch generally should not be less than 0.2 millimeter; And too little pitch can make the strength and stiffness of thread mechanism obviously reduce, and transmission campaign that can't be reliable and stable more can't transferring power.Because thread mechanism is realized the method for displacement and is had big limitation; In order to realize micro-displacement; Just need thread mechanism and linkage or gear mechanism etc. be used but this has obviously increased design and manufacturing cost again, strengthen the size and the weight of product.Therefore, can't realize the deficiency of micro-displacement in order to remedy the regular screw threads displacement mechanism, the present invention has designed a kind of micron order tool rest governor motion.
Summary of the invention
Consider to have the defectives such as deficiency that the regular screw threads displacement mechanism can't be realized micro-displacement now, the present invention provides a kind of micron order tool rest governor motion.This micron order tool rest governor motion manually to regulate, is controlled whole governor motion through it, thereby high accuracy is regulated the micro-displacement that tool rest is finally realized cutter.The entire mechanism simplicity of design is compact, and cost is low, high efficiency, be well positioned to meet governor motion accurately, steadily, requirement reliably.
The technical solution adopted for the present invention to solve the technical problems is: this micron order tool rest governor motion is made up of tool rest, fixture, scalable seat, base, screw rod, differential thread regulating part, clam member, spring and clamp nut etc.; With manual adjustments differential thread regulating part, thus the fine setting of realization cutter.Have two dovetail grooves on the scalable seat, interposition is equipped with a dozen logical screwed holes, and this screwed hole is connected with differential thread regulating part external screw thread.Base is provided with two guide rails; The scalable seat can slide up and down on base through it; Screw rod through up and down between two clam members and the base fixed relationship it is carried out axial restraint, have screwed hole on the both ends of the surface up and down of screw rod, it is completely fixed through clam member by screw.Be provided with spring between differential thread regulating part and the scalable seat, be used to eliminate thread pitch.Be provided with a clamp nut on the screw rod He below the scalable seat, and be provided with a spring washer between clamp nut and the scalable seat, after regulating completion, be used to pin current location, guaranteeing the accuracy of adjusting position.The differential thread regulating part has internal thread and external screw thread; Internal thread has identical rotation direction with external screw thread, and different pitch is when differential screw adjustments is revolved when turning around; Scalable seat displacement is the poor of internal thread and external screw thread pitch, thereby can realize the slight distance displacement.Consider the fine setting effect that realizes mechanism, internal thread and external screw thread are trapezoidal fine thread, and the pitch of internal thread is 1.75 millimeters; Externally threaded pitch is 1.85 millimeters, and promptly when differential screw adjustments rotated a circle, the displacement of realization was 0.1 millimeter; A circular scale is fixed in differential thread regulating part upper surface, and dial evenly is divided into 100 lattice, when the moving lattice of differential screw adjustments revolution; The tool displacement that realizes is 1 micron, thereby reaches micron-sized accurately adjusted design requirement.
The invention has the beneficial effects as follows: 1) the present invention adopts the differential thread adjusting device, simple in structure, cost is low, easily manufactured, can realize the micro-displacement that the regular screw threads gearshift can't be realized.2) the present invention can finely tune operation according to the indication of dial, so easy and simple to handle, it is accurate, quick to regulate.3) overall construction design of the present invention simple, help processing, make, assembling, can be good at satisfying the requirement that micron order is accurately regulated tool rest.
