The utility model discloses a rivet hole and pocket hole are processed out to a clamping, and the position relation of the two has obtained fine assurance, processed rivet hole and pocket hole error free position phenomenon, but two arbitrary selections carry out the matched stack, and convenient assembling can not appear turning round strength or bend the phenomenon of rivet when wearing the rivet.
Description
Technical field
The utility model relates to the bearing machining in mechanical field, specifically a kind of mould for the two half riveted joint retainer processing of ball bearing.
Background technology
The guidance mode of retainer can be divided into outer ring guiding, inner ring guides and ball guides several, the retainer that ball guides can realize the accurate guiding of steel ball, and because itself and inside and outside circle can keep comparatively wide arc gap simultaneously, so can be good at promoting greasy property, reduce friction and the temperature rise of bearing, ensure that bearing has good running status, be widely used in increasing occasion.Ball guides the pocket hole of retainer to be generally sphere, and being riveted by half retainer of two same shapes becomes overall structure, and its shape as shown in figure 1 and 2.
Such retainer is sphere due to pocket hole, therefore as the retainer of straight pocket hole, two halves laminating cannot be processed pocket hole simultaneously.General processing method is: car is shaping, face work, rough turn external diameter, rough turn internal diameter, apolegamy height, bore rivet hole and be divided into mark line, bore pocket hole, wear rivet and sell conjunctions, finish turning internal diameter, finish turning external diameter, Ex-all burr, pickling flaw detection, examine eventually.This processing method has the following disadvantages:
(1) because rivet hole and pocket hole have certain status requirement between the two, namely rivet hole will be distributed in the position between two pocket holes, therefore first must process rivet hole then to wear rivet and come for boring pocket hole operation location, the change of this positioning datum makes the position between rivet hole and pocket hole produce comparatively big error;
(2) processing of rivet hole is generally adopt to complete on little beakiron by hand, and rivet hole is along the circumferential direction ensured by the precision of drill jig completely with the position in diametric(al), and therefore positioning precision is not high.Further, because drill bit draws the factors such as inclined, though two halves retainer is for process simultaneously, but still dislocation can not be avoided, there will be when wearing rivet and turn round strength phenomenon, even by rivet bending.
Known by analyzing above, the key improving machining accuracy is to reduce clamping times, namely in clamped one time, processes rivet hole and pocket hole simultaneously.
Utility model content
The quality problems that there is error and cause are located for there is multiple clamping in solution prior art when processing retainer, the utility model provides a kind of mould for the two half riveted joint retainer processing of ball bearing, this mould achieves processes rivet hole and pocket hole in clamped one time simultaneously, avoiding the deviation that multiple bearing causes when processing rivet hole and pocket hole to occur, improve machining accuracy.
The utility model is the technical scheme solving the problems of the technologies described above employing: a kind of mould for the two half riveted joint retainer processing of ball bearing, comprise the axle be connected with lathe, packing ring, nut and gland, wherein, retainer to be processed is set on the workbench of axle, gland is set in axle, and by the cooperation of nuts and washers, retainer to be processed is fixed in axle, described gland is distributed with pockets processing passage and rivet hole processing channel, and pockets processing passage and rivet hole processing channel are identical with rivet hole number with the pocket hole on retainer to be processed respectively, position is corresponding, bottom surface around gland is provided with chuck II, upper surface around described workbench is provided with chuck I, the inner peripheral surface upper and lower of retainer to be processed is fastened on the sidewall of chuck II and chuck I respectively.
The top surface edge of described gland is provided with the domatic of inclination, so that chip removal.
Described gland is provided with locating hole, gland and axle are fixed through after this locating hole by alignment pin, to prevent gland and axle from relatively rotating, be convenient in following process that drill bit or milling cutter can both accurately by the pockets processing passage on gland and rivet processing channels.
Beneficial effect: the utility model compared with prior art, has the following advantages:
(1) the utility model adopts clamped one time to process rivet hole and pocket hole, and the position relationship of the two is guaranteed;
(2) the utility model adopts clamped one time to process rivet hole and pocket hole, the rivet hole therefore processed and pocket hole dislocation-free phenomenon, and two panels can be selected arbitrarily to carry out assembly;
(3) do not need extra manually on little beakiron, to bore rivet hole, eliminate a set of brill rivet hole mould, save man power and material;
(4) retainer of the utility model processing is easy to assembly, there will not be the phenomenon turning round strength or bending rivet when wearing rivet.

Detailed description of the invention
As shown in Figures 3 and 4, a kind of mould for the two half riveted joint retainer processing of ball bearing, comprise the axle 1 be connected with lathe, packing ring 3, nut 4 and gland 5, wherein, retainer 6 to be processed is set on the workbench 9 of axle 1, gland 5 is set in axle 1, and by the cooperation of nut 4 and packing ring 3, retainer 6 to be processed is fixed in axle 1, described gland 5 is distributed with pockets processing passage 501 and rivet hole processing channel 502, and pockets processing passage 501 and rivet hole processing channel 502 are identical with rivet hole number with the pocket hole on retainer 6 to be processed respectively, position is corresponding, bottom surface around gland 5 is provided with chuck II 7, upper surface around described workbench 9 is provided with chuck I 8, the inner peripheral surface upper and lower of retainer 6 to be processed is fastened on the sidewall of chuck II 7 and chuck I 8 respectively, thus complete the location of retainer 6 to be processed and fix.
Be more than basic embodiment of the present utility model, can do on above basis and further optimize and improve:
As, the top surface edge of described gland 5 is provided with the domatic of inclination, so that add the chip removal in man-hour;
And for example, described gland 5 is provided with locating hole 503, gland 5 and axle 1 are fixed through after this locating hole 503 by alignment pin 2, to prevent gland 5 and axle 1 from relatively rotating, be convenient in following process that drill bit or milling cutter can both accurately by the pockets processing passage 501 on gland 5 and rivet hole processing channels 502.
Being operating as when using Mould Machining retainer of the present utility model: half will keep that unwheeling is shaping, finish turning external diameter, finish turning internal diameter according to a conventional method, axle 1 is fixed on the base of CNC milling machine, be pressed on lathe base after adjustment position makes its circular runout reach OK range, to ensure axiality when turning round.By the chuck I 8 of axle 1 upper table 9 and the chuck II 7 of gland 5, retainer 6 is located the relative position of rear alignment pin 2 stationary gland 5 and axle 1, then fastening by packing ring 3 with nut 4, locate postpone and just can start axial feed processing pocket hole, round bur is first adopted to remove most of surplus, again with ball cutter processing to ensure roughness requirements, pockets processing well afterwards more bit change start to process rivet hole.Rivet hole carries out pickling flaw detection after machining flash removed, selects arbitrarily the riveted joint of two panels half retainer can form the retainer of complete set after cleaning.
