Abstract
An apparatus for trimming an ultra-hard abrasive disc is composed of a fixture, an installation frame fixed on the mainshaft box, 3 friction wheels, an adhesive diamond disc, and two drive mandrels with one end connected to friction wheels and another end connected to said abrasive diamond disc for driving said adhesive diamond disc and controlling its working position.
Description
Technical field
Patent of the present invention relates to a kind of trimming device of grinding tool process equipment, particularly a kind of hard grinding wheel.Specifically, utilizing friction pulley to transmit frictional force drives diamond-impregnated grinding wheel and rotates and repair a kind of hard grinding wheel and also claim the CBN emery wheel.
Background technology
In the manufacturing of machine components, for improving workpiece quality and precision, method for grinding extensively adopts.The face that grinding tool (emery wheel) contacts with workpiece in grinding process can wear and tear and be out of shape.For guaranteeing the surface quality and the precision of workpiece, must repair grinding tool (emery wheel).Method for trimming to plain wheel adopts diamond pen (natural diamond of a grain of rice size is welded on according on the base steel that the needs shape is installed) to be fixed on certain transmission mechanism emery wheel is repaired usually.Because plain wheel is softer, it is very fast to wear and tear in grinding, and the finishing number of times is more, and emery wheel is short service life, and production efficiency is low, and labour intensity is big.
For life-span that prolongs emery wheel and surface quality and the efficient that improves workpiece, a kind of hard grinding wheel (CBN) is widely adopted, because the natural diamond wearing and tearing that the traditional diamond pen of the very hard employing of hard grinding wheel is welded on when repairing on the diamond pen are very fast, in case therefore the natural diamond corner angle just wear away and hard grinding wheel can't be trimmed to due requirement in finishing, directly influence workpiece surface quality then.
Summary of the invention
Goal of the invention: the purpose of patent of the present invention is that a kind of simple in structure, convenient, processing ease of mounting or dismounting is provided at the deficiencies in the prior art, and has the trimming device of a kind of hard grinding wheel of good actual use effect.
Technical scheme: the trimming device of the described hard grinding wheel of patent of the present invention comprises being installed in the clamp body that is used for holding workpiece on the main shaft, mounting bracket, three friction pulleys, two drive mandrel and a diamond-impregnated wheel and two fixed covers that are used to install bearing and mandrel; This mechanism drives friction wheel from rotation by being installed in the clamp body that is used for holding workpiece on the main shaft, two drive mandrel are installed in the corresponding fixed cover by bearing respectively, two fixed covers are fixed on the mounting bracket, by three friction pulleys, two drive mandrel the position of diamond-impregnated wheel is gone on the needed operating position, mounting bracket is fixed on the main spindle box.
Light in order to install and remove, the material selection aluminium alloy of mounting bracket.
For easy to adjust, mounting bracket is provided with the adjustment link, and the back that puts in place gets final product with screw lock.
The operation principle of patent of the present invention mechanism is: diamond-impregnated wheel is plated in it on base steel with electric plating method by the natural diamond of numerous granule shape.Diamond-impregnated wheel and CBN hard grinding wheel must produce relative motion ability trimming wheel, in case the direction of rotation of emery wheel determines that the direction of rotation of diamond-impregnated wheel is just determined.The rotation of diamond-impregnated wheel is achieved in that the clamp body by being installed on the main shaft drives three friction wheel from rotation that cooperatively interact near friction pulley by the frictional force effect, and then drives diamond-impregnated wheel rotation and finishing hard grinding wheel.Three friction pulleys, two drive mandrel go to needed operating position with the position of diamond-impregnated wheel, i.e. the position at hard grinding wheel place on the grinding machine.For easy to adjust, coarse positioning of the screw that mounting bracket links to each other with main spindle box, another is designed to the distance that the waist-hole type shape can be regulated the clamp body on friction pulley and the main shaft, and on mounting bracket, be provided with two Hough hole adjustment laterally, position longitudinally.Use screw lock after putting in place.
Beneficial effect: the remarkable advantage of patent of the present invention is to have reduced design and manufacturing cost, and is simple in structure, and mounting or dismounting are convenient, the finishing hard grinding wheel is effective, can increase work efficiency, and is particularly useful for producing in batches; Improve part processing quality and precision.
Description of drawings
Fig. 1 is the structural representation of patent of the present invention, and Fig. 2 is Fig. 1 side-looking direction schematic diagram.
The specific embodiment
Be described further below in conjunction with accompanying drawing (omitting the associated mechanical structure in the main spindle box among the figure).
The correcting device of the described hard grinding wheel of patent of the present invention comprises bolt 1, mounting bracket 2, friction pulley 3, drive mandrel 4, fixed cover 5, bearing 6, friction pulley 7, friction pulley 8, drive mandrel 9, fixed cover 10, bearing 11, diamond-impregnated wheel 12, clamp body 13.The clamp body 13 that is installed on the main shaft drives friction pulley 3 rotations near friction pulley 3 by the frictional force effect, the two ends of drive mandrel 4 link to each other with friction pulley 7 with friction pulley 3 respectively, drive mandrel 4 is installed in the fixed cover 5 by bearing 6, and fixed cover 5 is fixed on the mounting bracket 2.Drive friction pulley 7 rotations by drive mandrel 4, and friction pulley 7 drives friction pulley 8 rotations near friction pulley 8 by the frictional force effect, the two ends of drive mandrel 9 are connected with diamond-impregnated wheel 12 with friction pulley 8 respectively, drive mandrel 9 is installed in the fixed cover 10 by bearing 11, fixed cover 10 is fixed on the mounting bracket 2, it is horizontal to be provided with two Hough hole adjustment on mounting bracket 2, position longitudinally, the back screw lock puts in place, guarantee that clamp body 13 is near friction pulley 3, friction pulley 7 is near friction pulley 8, drive diamond-impregnated wheel 12 rotations by frictional force transmission layer by layer, thereby finish the makeover process of hard grinding wheel.Coarse positioning of the screw that mounting bracket 2 links to each other with main spindle box is a bolt 1, and another is designed to the distance that the waist-hole type shape is regulated the clamp body 13 on friction pulley 3 and the main shaft.Diamond-impregnated wheel 12 is to be matrix with 45 steel, and periphery is inlayed a circle diamond, and the finishing hard grinding wheel is finished with peripheral this circle diamond exactly.Diamond-impregnated wheel 12 must produce relative motion ability trimming wheel with the CBN hard grinding wheel, in case the direction of rotation of emery wheel determines that the direction of rotation of diamond-impregnated wheel 12 is just determined.In order to ensure the finishing effect of CBN hard grinding wheel, the CBN hard grinding wheel must move back and forth several times.For this mechanism mounting or dismounting light, the material selection aluminium alloy of mounting bracket 2.
