Description
Technical field
The present invention relates to utilize the initiatively technical field of measuring technique control deep groove ball bearing assembling hold depth.
Background technology
The deep groove ball bearing of heavy load, because the enhancing of its bearing capacity, the steel ball number that need pack into increases, and adopts general assembly technology to assemble, and must process ball-loading hole on the inside and outside lasso of bearing.The height of the bottom of ball-loading hole and lasso raceway is referred to as to assemble hold depth, can pack into smoothly in order to make steel ball, possesses suitable assembling hold depth again, and this just requires the assembling hold depth of the necessary strict control ball-loading hole of operator.At present, do not have special-purpose ball-loading hole grinding machine, this all series products all adopts manual easy device grinding, does not only guarantee the assembling hold depth, also has a lot of dangerous hidden danger simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of special grinder for deep groove ball bearing charging hole, can improve the Grinding Machining Quality of deep groove ball bearing ball-loading hole greatly, improve the assembly precision of bearing, the personal injury of avoiding workman's hand grinding to cause.
In order to achieve the above object, technical scheme of the present invention is as follows:
Special grinder for deep groove ball bearing charging hole is mainly by lathe bed, measurement bay feeding slide unit 1, grinding wheel spindle reciprocating feed slide unit 2, measurement bay 3, grinding wheel spindle 4, spring perch 5, trimmer 6 and workpiece feeding slide unit 7 are formed, the measurement bay feeding slide unit 1 that is driven by hydraulic jack is installed on the lathe bed, and measurement bay 3 is installed on the measurement bay feeding slide unit 1; The grinding wheel spindle reciprocating feed slide unit 2 that is driven by servomotor, ball-screw is installed on the lathe bed, and the grinding wheel spindle of being controlled by servo-drive system 4 is installed on the grinding wheel spindle reciprocating feed slide unit 2; The spring perch 5 that is driven by hydraulic jack is the mechanical elasticity anchor clamps, is installed on the workpiece feeding slide unit 7; The trimmer 6 of emery wheel is installed on the workpiece feeding slide unit 7, is installed on the lathe bed by the workpiece feeding slide unit 7 of driven by servomotor.
Connect a single-point gauge on the above-mentioned measurement bay 3.
The invention has the beneficial effects as follows: this grinding machine is the crudy height not only, and has improved the assembly precision of production efficiency and bearing widely, has reduced working strength of workers.
Description of drawings
Fig. 1 is the structural representation of special grinder for deep groove ball bearing charging hole of the present invention.
Among the figure: 1, measurement bay feeding slide unit, 2, grinding wheel spindle reciprocating feed slide unit, 3, measurement bay, 4, grinding wheel spindle, 5, spring perch, 6, trimmer, 7, workpiece feeding slide unit.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done description in further detail:
Special grinder for deep groove ball bearing charging hole of the present invention is the supplying position by active measuring system control workpiece, guarantees that the assembling hold depth of ball-loading hole is controlled in the 0.03mm.
As shown in Figure 1, special grinder for deep groove ball bearing charging hole mainly comprises measurement bay feeding slide unit 1, grinding wheel spindle reciprocating feed slide unit 2, measurement bay 3, grinding wheel spindle 4, spring perch 5, trimmer 6 and 7 seven parts of workpiece feeding slide unit.Measurement bay 3 is installed on the measurement bay feeding slide unit 1, adopts hydraulic jack to drive and moves back and forth; Grinding wheel spindle reciprocating feed slide unit 2 adopts servomotor, ball-screw to drive, by the supplying position and the oscillating grinding of servo-drive system control grinding wheel spindle 4; Spring perch 5 adopts the mechanical elasticity anchor clamps, is driven by hydraulic jack; The trimmer 6 of emery wheel is installed on the workpiece feeding slide unit 7, and the assurance servo-drive system can in time be fed back the relative position between workpiece and the emery wheel; Workpiece feeding slide unit 7 adopts driven by servomotor, determines the supplying position of workpiece according to the actual ditch depth of workpiece.
Grinding machine of the present invention can be finished the inner ring of deep groove ball bearing, the grinding of outer ring ball-loading hole, its range of work: inner ring φ 60～φ 120mm, outer ring φ 120～φ 240mm.Adopt cubic boron nitride abrasive wheel to carry out grinding.The course of work of this grinding machine is as follows: new emery wheel will be repaired before grinding, the drive motors of crawl grinding wheel spindle reciprocating feed slide unit 2 at first, grinding wheel spindle 4 is parked on the open-ended position, the drive motors of crawl workpiece feeding slide unit 7 then, when the Buddha's warrior attendant nib of trimmer 6 contacts with wheel face, allow the trace of grinding wheel spindle 4 reciprocating beginning emery wheels repair, trim after the emery wheel, the sample circle is installed on the spring perch 5, starting clamping cylinder tightens the sample circle, adopt the hand feed mode that the surface to be ground of sample circle is leaned against on the grinding face of emery wheel, at this moment the physical location X of the servo feed system of workpiece record sample circle
0, this process is referred to as tool setting usually.After good cutter, start the initiatively oil cylinder of measurement bay feeding slide unit 1, initiatively measurement bay feeding slide unit 1 drives measurement bay 3 convergence sample circle bottoms of trench, detect the actual ditch depth position of sample circle raceway groove by the single-point gauge of installing on the measurement bay 3, the measuring system sampling, initiatively measurement bay feeding slide unit 1 withdraws from then, take down the sample circle, change the workpiece that to process, initiatively measurement bay feeding slide unit 1 carries out the feeding measurement second time, measuring system is taken a sample for the second time, and measuring system will be determined the supplying position of workpiece according to the difference of wanting processing work and sample circle ditch depth.
When the ditch depth of wanting processing work is more deep than sample circle ditch, workpiece will be bigger to cutter position than the reality of sample circle with respect to the supplying position of emery wheel, otherwise workpiece will be littler to cutter position than the reality of sample circle with respect to the supplying position of emery wheel.For example, after emery wheel was repaired for the first time, the residing position of workpiece spindle was made as X when we contacted the ball-loading hole of standard sample circle with the wheel grinding surface
0, the ditch depth of sample circle is H, the ditch depth of workpiece is H
1, wanting to guarantee to want the standard of processing work to assemble hold depth, the supplying position of workpiece spindle just should be X
0+ (H
1-H).Therefore, according to top formula, we just can be at an easy rate ditch depth difference by sample circle and workpiece to be machined guaranteed desired assembling hold depth.
