Description
Technical field the utility model relates to a kind of machinery part surface abrasive machining device.
Background technology is present, and surperficial Crowning Grinding still adopts conventional grinding attachment, and the electric main shaft of the emery wheel that is made of motor, grinding wheel spindle and emery wheel in this device is located on the bistrique seat, and motor and emery wheel partly are positioned at outside the bistrique seat.This bistrique seat is fixed on the horizonal base plate.This base plate front portion corresponding with emery wheel that is located on the workbench is provided with two T type groove bolts, and its T connector is corresponding with the T type guide groove on the workbench, respectively establishes the T type groove corresponding with T type guide groove on the workbench bolt and a square nut at this middle part, base plate back.Establish adjustment seat at this base plate rear end, it links to each other with base plate by square toes cylinder end clamping fixed screw and outer-hexagonal bolt.The sliding pin that is located on this conciliation seat is corresponding with the guide groove on the workbench.Above-mentioned grinding attachment adopts cut-in type and small oscillation mode to carry out grinding when grinding usually, its grinding process is: the grinding wheel spindle axis is contour and parallel with the work centre line that has constant slope, therefore the surface of the work that processes is a straight edge line, must just can reach the surperficial convexity of workpiece requirement through twice reconditioning processing.Its weak point is: 1 because the grinding of a workpiece needs just can finish through twice grinding, so labor strength to be big on two equipment, and production efficiency is low and be not suitable for producing in batches.2 twice pair of emery wheels do not have localization criteria, thereby mismachining tolerance is big, causes the percent defective height.3 production difficulty are big, and surface roughness is not up to standard.
The summary of the invention the purpose of this utility model provides a kind of grinding attachment that once can process satisfactory surface of the work convexity on an equipment.The utility model mainly is to set up the mechanism that the bistrique seat is moved up and down on the basis of existing technology, this travel mechanism mainly contains: vertical location-plate, lifting screw mandrel, handwheel, percentage road core, calibration loop, pointer and scale, wherein vertically location-plate is vertically fixed on a side of base plate and parallel with grinding wheel spindle, this vertical location-plate and base plate form right angle bent plate of the prior art.This vertical location-plate is respectively established a pair of vertical cylindrical void up and down, respectively establishes a screw in each vertical cylindrical void, and they are threaded with screw corresponding with the bistrique seat side of its split above the base plate.Vertically be fixed with bearing block by securing member on the location-plate, be provided with vertical screw mandrel in the axis hole of this bearing block, the part that this screw mandrel is positioned at below the bearing block is threaded with the screw on bistrique seat top, the part that screw mandrel is positioned at above the bearing block is fixedlyed connected with cover percentage road core thereon by pin key, and this percentage road core links to each other with the calibration loop that is trapped among its outside by spring leaf.Be provided with the handwheel that connects together with it by pin key in the screw mandrel upper end, an end that has emery wheel electricity main shaft to pass at the bistrique seat is fixed with an end of pointer in addition, and the free end of this pointer is corresponding with the scale plate that is located at vertical location-plate side.Be preferably in the bistrique seat and establish the square collision block support that the plane makes progress towards the side of lathe, this support is provided with the protection collision block.
The course of work of the present utility model is as follows: rotation hand wheel, can become to making the grinding tool seat to move up and down by screw mandrel, its amount of movement can show by calibration loop and scale plate, and general emery wheel axis is than the workpiece spindle height that has constant slope, contacting of workpiece and emery wheel is contacted by line become a contact.When the oil cylinder that utilizes former grinding machine drives the reciprocal grinding work piece of emery wheel because the oblique bus rotary track of workpiece is a hyperboloid, cylindrical grinding wheel then with bi-curved two end in contact, and with its grinding.So the workpiece middle part that has constant slope that is not ground just forms certain convexity.
The utility model has following advantage compared to existing technology:
1. fine grinding operation can be finished on same equipment with finishing convexity operation, increases work efficiency more than 50%.
2. the curve that processes is stable, and symmetry is good, and the convexity amount is stable.
3. the grinding face quality improves two accuracy classes, has improved bearing service life.
4. eliminated the production difficulty, easy and simple to handle, grasp easily, can regulate desired convex value arbitrarily.
