Figure 18 is the process schematic representation of processing miniature bearing inner ring, and its technical process is: endoporus-inner ring base substrate turn-over of turning inner ring base substrate, chamfering, turning dustproof groove-inner ring base substrate turn-over in turning raceway-turning, chamfering, dustproof groove in the turning other end.
Realize the production line of the automatic processing miniature bearing inner ring of above-mentioned technical process, as shown in Figure 2, comprise 4 chassis beds, be followed successively by lathe one 1a, lathe two 1b, lathe three 1c and lathe four 1d, its disk feeder 8 is located at lathe one 1a mono-side.Carriage structure 2 on its lathe one 1a comprises the length feed planker 25 of the axially parallel of direction of feed and main shaft 3.Carriage structure 2 on its lathe two 1b comprises the axial vertical traverse feed planker 21 of direction of feed and main shaft 3.Its lathe three 1c and dragging plate mechanism 2 on lathe four 1d comprise the oblique feeding planker 22 that traverse feed planker 21 that direction of feed is vertical with main shaft 3 and direction of feed and main shaft 3 tilt, the angle of the direction of feed of its oblique feeding planker 22 and main shaft 3 axis is 15 ° ~ 30 °, is preferably 20 °.
The structure of its oblique feeding planker 22 as shown in figure 16, the cutter 20 of being located at above-mentioned oblique feeding planker 22 is parallel with main shaft 3, the afterbody of its oblique feeding planker 22 is provided with and drives oil cylinder 23, and the angle of the direction of feed of described oblique feeding planker 22 and described main shaft 3 axis is 20 °.The track that its oblique feeding carriage structure 22 drives the relative clamping of cutter 20 to be arranged at workpiece 10 feedings on lathe spindle 3 is oblique line.
The benefit of said structure is, only need to arrange one and drive oil cylinder 23, can realize tool feeding motion.Compare with two-way feed planker in prior art, structure realizes more simple, controls and is also more prone to.
Again, in prior art cutter in traverse feed in process contact with workpiece, due to the direction of feed of cutter and the axis of workpiece vertical, it is larger at the moment impact contacting, easily damage is caused in the surface of cutter and workpiece, affect the service life of cutter and the machining accuracy of workpiece.And the planker of oblique feeding in the present embodiment, angle between its direction of feed and lathe spindle axis is 15 ° ~ 30 °, be preferably 20 °, its cutter impacts less in the process of contact workpiece, stress comparatively disperses, extend the service life of cutter, the machining accuracy of workpiece is also relatively easily controlled.
It should be noted that, traverse feed planker 21 and oblique feeding planker 22 in the present embodiment, interior chamfering and the raceway of machining bearing inner ring simultaneously, and in prior art, the interior chamfering of machining bearing inner ring and raceway need to carry out on different lathes.So, the miniature bearing lasso lathe for machining operation of the present embodiment is more concentrated, and working (machining) efficiency is higher.
Use above-mentioned production line processing miniature bearing inner ring, only need to pour in disk feeder 8 inner ring blank is random.Its inner ring blank is neat in disk feeder 8 auto arrangement, and become rolling from translation, along material road 11, enter elevator 9, its elevator 9 is promoted to eminence by inner ring blank by lower, via track 11, enter in the automatic feed mechanism 1 of lathe one 1a again, by automatic feed mechanism 1, inner ring blank is pushed in the clamping device of main shaft 3, planker drives cutter to complete the endoporus turning processing to inner ring blank.Inner ring blank after processing falls into material receiving mechanism 4 automatically, and landing is to shaking in multigraph press 5 voluntarily, and in its vibrations multigraph press 5, inner ring blank enters lathe two 1b via elevator 9 again, completes the turning processing of inner ring blank raceway.
It should be noted that, because inner ring blank is being delivered in lathe two 1b and being added man-hour by lathe one 1a, need to carry out turn-over to blank, therefore, what between its lathe one 1a and lathe two 1b, be provided with automatic turnover can condiment road.Its automatic turnover can condiment road as shown in Figure 14,15, comprise the material loading road 91 of being located at material 11 tops, road and being connected with described elevator 9, the bottom surface of its material loading road 91 ends is left Gong the workpiece adapting with workpiece and by material loading road 91, is fallen into the blanking port 93 in material road 11, the rotating direction of inner ring blank in material loading Dao91Yu Liao road 11 is contrary, the downward-sloping setting in Qi Liao road 11 and the crooked charging aperture that extends to next automatic feeding mechanism 1; Its material loading road 91 ends are provided with baffle plate 94, and the guiding inner ring blank that its baffle plate 94 bottoms are connected with arc enters the guided plate 95 of expecting road 11, and its guided plate 95 is to downward-extension and by baffle plate 94 91 belows bendings to material loading road.Its material loading road 91 comprises base plate 96, fixed side 97 and the adjustable side plate 98 that can move with respect to fixed side 97, and adjustable side plate 98 is L shaped, and base plate 96 is provided with a pair of waist-shaped hole 99, and pair of bolts is fixed on adjustable side plate 98 on base plate 96 through waist-shaped hole 99.
Can working in the following manner in condiment road of the utility model automatic turnover: workpiece by a upper processing unit (plant) completion of processing after, rolling enters material loading road, from blanking port along guided plate, fall into material road 11, the rotating direction of workpiece reverses, and via bending, extend to next processing unit (plant) charging aperture Liao road 11 and continue to roll, above circulation process implementation the automatic turnover of workpiece.When the width of the workpiece of carrying changes, by adjusting the adjustable side plate in material loading road, can change the width in material loading road.This kind of automatic turnover can condiment road, without additionaling power, simple in structure in turn-over process.
In like manner, inner ring blank, more successively by lathe three 1c and lathe four 1d, completes the turning processing of interior chamfering and dustproof groove etc.
Figure 19 is the process schematic representation of processing miniature bearing outer ring, and its technical process is: endoporus-outer ring base substrate turn-over of turning outer ring base substrate, the outer chamfering of turning raceway-turning, turning dustproof groove-outer ring base substrate turn-over, the outer chamfering of the turning other end, dustproof groove.
Accordingly, automatically process the production line of miniature bearing outer ring, as shown in Figure 3, comprise 4 chassis beds, be followed successively by lathe one 1a, lathe two 1b, lathe three 1c and lathe four 1d, its disk feeder 8 is located at lathe one 1a mono-side.It is compared with the production line of automatically processing miniature bearing inner ring shown in Fig. 2, and difference is that the carriage structure 2 on its lathe one 1a, lathe two 1b, lathe three 1c and lathe four 1d is the length feed planker 25 of the axially parallel of direction of feed and main shaft 3.All with shown in Fig. 2 the production line of processing miniature bearing inner ring is identical automatically for its operation principle and the mode of production.
In addition, it should be noted that, the specific embodiment described in this description, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this description is only to the explanation of the utility model structure example.All equivalence variation or simple change of doing according to described structure, feature and the principle of the utility model patent design, are included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
