Description
Technical field
The utility model relates to bearing grinder technical field, relates in particular to a kind of easy grinding process for raceway convexity, the diamond pen microfeed structure when interpolation trimming wheel.
Background technology
In the Crowning Grinding of raceway, sometimes need crushing to become the protuberance shape of needs, then remove grinding bearing lasso with the emery wheel trimming, make lasso reach the protuberance shape needing.When trimming wheel, adopt sometimes two servo interpolation finishings.Because effective feed distance of diamond pen direction generally only has 0.01mm left and right, so, on the Stroke Control market about it, there is various ways, as ordinary steel guide rail, line slideway, spring leaf etc.The shortcoming that they are general or complex structure, or mechanical trip is not easy to control, or there is no pretightning force in motion process direction, and cannot eliminate the fit clearance between screw mandrel, precision is all unstable.
Utility model content
The purpose of this utility model is to provide a kind of diamond pen microfeed structure for bearing grinder interpolation finishing, its have simple in structure, be easy to the feature that realizes and can eliminate diamond pen screw mandrel fit clearance in motion process, the problems referred to above that exist when solving prior art middle (center) bearing grinding machine convexity interpolation trimming wheel.
For reaching this object, the utility model by the following technical solutions:
A kind of diamond pen microfeed structure for bearing grinder interpolation finishing, it comprises diamond pen, Buddha's warrior attendant penholder, holder, large gland, adapter sleeve and drive unit, wherein, described adapter sleeve comprises connecting portion and is the helical pitch portion on the face of cylinder, the drive end of described connecting portion connecting drive device, described helical pitch portion connects Buddha's warrior attendant penholder, and described helical pitch portion overcoat has large gland, one end of described large gland is fixed on holder, the other end and connecting portion have gap, and on described large gland, offer the shoulder hole of one group of symmetry, push rod is arranged in shoulder hole, the front end of described each push rod is connected with connecting portion by bolt, rear end is provided with pretension parts.
Especially, described drive unit is ball-screw, and the nut seat of described ball-screw is connected with adapter sleeve by set bolt.
Especially, the other end with respect to push rod is set of described pretension parts is provided with jackscrew, regulates the pretightning force size of pretension parts by jackscrew.
Especially, described pretension parts are Compress Spring.
Especially, one end arranged outside that jackscrew is set on described large gland has cover plate, on described cover plate, offers through hole, and described Buddha's warrior attendant penholder stretches out outside cover plate through through hole.
Especially, between described through hole and Buddha's warrior attendant penholder, be provided with sealing ring.
The beneficial effects of the utility model are that compared with prior art the described diamond pen microfeed structure for bearing grinder interpolation finishing has the following advantages:
1) simple in structure, compactness, part is made easily, is convenient to design.
2) the cylindrical fit face between adapter sleeve and large gland plays the effect of short distance helical pitch, and design gets up to be more prone to convenient with processing;
3) can be simply Stroke Control in certain scope;
4) can in the scope of stroke, have pretightning force, feed accuracy is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the diamond pen microfeed structure for bearing grinder interpolation finishing that provides of the utility model specific embodiment 1.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
Refer to shown in Fig. 1, Fig. 1 is the structural representation of the diamond pen microfeed structure for bearing grinder interpolation finishing that provides of the utility model specific embodiment 1.
In the present embodiment, a kind of diamond pen microfeed structure for bearing grinder interpolation finishing comprises diamond pen 1, Buddha's warrior attendant penholder 2, holder 3, large gland 4, adapter sleeve 5 and ball-screw 6, described diamond pen 1 is fixed on one end of Buddha's warrior attendant penholder 2, described adapter sleeve 5 comprises connecting portion 50 and is the helical pitch portion 51 on the face of cylinder, described connecting portion 50 connects the nut seat 60 of ball-screw 6 by being connected and fixed bolt, the end of described helical pitch portion 51 connects Buddha's warrior attendant penholder 2 by set bolt, and described helical pitch portion 51 overcoats have large gland 4, one end of described large gland 4 is fixed on holder 3 by set bolt, the other end and connecting portion 50 have gap delta, and on described large gland 4, offer the shoulder hole of one group of symmetry, push rod 7 is arranged in shoulder hole, the front end of described each push rod 7 is connected with connecting portion 50 by bolt, rear end is provided with Compress Spring 8, in the shoulder hole of described large gland 4, coordinate Compress Spring 8 that jackscrew 9 is installed, by jackscrew 9, regulate the pretightning force size of Compress Spring 8.
One end arranged outside that jackscrew 9 is set on described large gland 4 has cover plate 10, on described cover plate 10, offers through hole, and described Buddha's warrior attendant penholder 2 stretches out outside cover plate 10 through through hole.Between described through hole and Buddha's warrior attendant penholder 2, be provided with sealing ring 11.
Cylindrical fit face between described adapter sleeve 5 and large gland 4 just can play helical pitch.Push rod 7 is set between adapter sleeve 5 and large gland 4 and not only limits with Compress Spring 8 the stroke δ that diamond pen 1 moves, and push rod 7 also plays a guide effect (rotatablely moving of adapter sleeve 5 having been become to the rectilinear motion in ball-screw 6 directions) in motion process, also make diamond pen 1 is the pretension of spring 8 pressure by compression all the time simultaneously in the stroke range of δ, eliminated ball-screw 6 gap at the volley, thereby it is more accurate to complete the feed accuracy of diamond pen 1.
During work, ball-screw 6 rotates under the driving of servomotor, because the locus of ball-screw 6 is constant, the nut seat 60 of its upper end is connected with adapter sleeve 5, push rod 7, can not rotate, so its nut seat 60 just moves with adapter sleeve 5 on the axial direction of ball-screw 6, thereby drive Buddha's warrior attendant penholder 2 and diamond pen 1 to move, complete the interpolation finishing of diamond pen 1.
In the course of the work, because effective feed distance of diamond pen 1 generally only has 0.01mm left and right, so as long as control the distance δ > 0.01mm of large gland 4 and adapter sleeve 5, can satisfy the demand.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
