Description
Technical field
The invention belongs to the grinding machine installation and use utensil, relate in particular to for device grinding tool or the workpiece feeding or calibration.
Background technology
Grinding machine grinds surface of the work by the High Rotation Speed emery wheel is housed, and makes surface of the work bright and clean or improve Workpiece Machining Accuracy.In process, emery wheel contacts with workpiece, and emery wheel is easy to wear or damage, and needs often to change emery wheel, and emery wheel becomes the main consumables of grinding machine.Current installation emery wheel, be directly emery wheel is placed between upper anchor clamps and the lower clamp, chucking, be fixed on the driving shaft, the emery wheel concentricity is by manual setting.Its defective is: owing to being provided with the fit-up gap between anchor clamps cylindrical and the emery wheel endoporus, be difficult to capturing position during installation, and consuming time many; Easily produce off-centre between emery wheel and the anchor clamps, installation accuracy is low; Affect Workpiece Machining Accuracy, efficient is low; Emery wheel is short service life, and spare parts consumption is high.
Summary of the invention
The defective that exists in order to overcome prior art the purpose of this invention is to provide a kind of grinding wheel of external grinder means for correcting.Improve the emery wheel installation accuracy, improve machining accuracy and working (machining) efficiency, improve crudy; Prolong emery wheel service life, reduce spare unit consumption.
Grinding wheel of external grinder means for correcting, characteristics are to be connected and composed by bracket frame, bearing block, mandrel and elastic adjusting mechanism, establish bearing block on the bracket frame, with being loaded in the bearing block with the frustum of a cone of lower clamp taper fit and the mandrel that is provided with bearing; Establish C type frame on the bracket frame oblique arm, elastic adjusting mechanism is fixed on the C type frame, is connected mutually with the emery wheel edge; When proofreading and correct emery wheel, mandrel is fixed on the bracket frame, and the lower clamp chuck is contained on the mandrel, and emery wheel is fixed by nut and screw thread by upper clamp.During the mandrel rotation, the emery wheel edge contacts with elastic adjusting mechanism, automatically adjusts the concentricity of emery wheel and anchor clamps.After proofreading and correct end, lay down nut and mandrel, anchor clamps and emery wheel are still clamped by bolt, and anchor clamps and emery wheel integrally are installed on the driving shaft of grinding machine.
Further improve, described bracket sets up bearing block, is positioned under the mandrel, and mandrel is loaded in the bearing block by bearing; Bracket frame oblique arm is established 2-3 C type frame, and elastic adjusting mechanism is fixed on the C type frame.Many C type framves are set, a plurality of elastic adjusting mechanisms can be set, the applicable different emery wheel of diameter of proofreading and correct.
Further improve, described mandrel establish from top to bottom screw thread with the nut cooperation, establish circular cone stage body and lower clamp taper fit, to establish bearing corresponding with bearing block, for timing.
Further improve, described elastic adjusting mechanism is made of turning rolls, roller, spring and dial gauge.Rolling bearing is respectively installed at the roller two ends, inserts in the turning rolls again, fixes with pin, and two of pin can move forward and backward in the groove frame C type piece, also can play the guide rod effect; Turning rolls rear projection place tangles stage clip, and heads on the dial gauge that is fixed on the frame, can detect so the just offset of sand loading wheel, and when offset was larger, spring was compressed, and acting in opposition resets during the emery wheel rotation in emery wheel.
Compared with prior art, advantage is: novel, simple in structure, easily to make, and cost is low; Operation is reliable, and is flexible, the concentricity between emery wheel and the anchor clamps of can harmonizing quickly, and offset can be controlled in 20; Improve the emery wheel installation accuracy, be conducive to improve machining accuracy and work efficiency, improved product quality and prolong emery wheel service life, reduced the consumption of spare unit.
Description of drawings
The invention will be further described for the contrast accompanying drawing.
Fig. 1 is grinding wheel of external grinder means for correcting structural representation.
Fig. 2 is the A section enlarged drawing of Fig. 1.
The specific embodiment
Can be found out by Fig. 1, Fig. 2, the grinding wheel of external grinder means for correcting is connected and composed by bracket frame 1, bearing block 2, mandrel 3 and elastic adjusting mechanism, establishes bearing block on the bracket frame, is positioned under the mandrel, and bearing 5 is loaded in the bearing block.Establish C type frame 7 on the bracket frame right side oblique arm 6, elastic adjusting mechanism is fixed on the C type frame.Timing, mandrel are fixed on the bracket frame, and lower clamp 12 is sleeved on the mandrel, and emery wheel 14 places on the lower clamp, and upper anchor clamps 13 compress, and are fixed by nut 4, screw thread 15, and the emery wheel edge is connected mutually with elastic adjusting mechanism.In mandrel when rotation,, the emery wheel edge contacts with elastic adjusting mechanism, deflects away from the part pressurized, draws close to the center, rotate limited number of time after, the just concentricity of automatic calibration emery wheel and anchor clamps.At this moment, will be distributed in again, nine set bolts 18 on the upper and lower anchor clamps of anchor clamps are fastening.After proofreading and correct end, loosen nut, tiltedly coring axle.When emery wheel is installed, with anchor clamps and emery wheel integrally on the fixed drive axle.
Be it can also be seen that by Fig. 1, mandrel top is established screw thread and is cooperated with nut, and the middle part is established the frustum of a cone and cooperated with lower clamp, and it is corresponding with bearing block that bearing is established in the bottom.
Be it can also be seen that by Fig. 1, bracket sets up bearing block, is positioned under the mandrel, and mandrel installing bearing is loaded in the bearing block.Establish a C type frame on the bracket frame oblique arm, elastic adjusting mechanism is fixed on the C type frame, is connected mutually with the emery wheel edge.
As seen from Figure 2, elastic adjusting mechanism is made of turning rolls 8, roller 9, spring 10 and dial gauge 11, rolling bearing is respectively installed at the roller two ends, insert again in the turning rolls, fix with pin 17, two of pin can move forward and backward in the groove frame C type piece, also can play the guide rod effect, turning rolls rear projection place tangles stage clip, and heads on the dial gauge that is fixed on the frame.Emery wheel mechanism adjusts static balance by the balance weight in the static balance groove 16.
