The described particular manufacturing craft that is used for processing bearing retainer pocket, its mandrel unit is made of mandrel, counterdie, patrix, bearing, bearing gland, pad c, pad a, pad b and nut, and on mandrel, being arranged in order installation from right to left, retainer to be processed is fixed between the upper die and lower die of screw rod left end.
The described particular manufacturing craft that is used for processing bearing retainer pocket, its positioning unit is mainly by index dial, backstay, spring with hold out against nut and constitute, wherein index dial is installed between the pad b and pad a on the mandrel, and pad c is near pad a right-hand member and hold out against bearing inner race; Spring is contained in the special-purpose locating hole on the pedestal lower semi-body, and backstay passes spring and is screwed in the terminal holddown spring of backstay by holding out against nut; Index dial and retainer coupling to be processed.
Because adopt aforesaid technical scheme, the present invention has following superiority:
This particular manufacturing craft is simple to operate, convenient mounting and clamping, and the production efficiency height, stable processing quality also can effectively reduce production costs, and is applicable to small batch production.
Description of drawings
Fig. 1 is the particular manufacturing craft structural representation that is used for processing bearing retainer pocket;
Among Fig. 1: the 1-index dial; The 2-nut; 3-pad a; 4-pad b; The 5-screw rod; The 6-mandrel; The 7-bearing gland; The 8-bearing; 9-pad c; The 10-pedestal; The 11-backstay; 12-holds out against nut; The 13-spring; The 14-patrix; The 15-counterdie; The 16-handwheel; 17-mandrel unit; The 18-positioning unit.
The specific embodiment
As shown in Figure 1: the particular manufacturing craft that is used for processing bearing retainer pocket of the present invention, mainly by pedestal 10, mandrel unit 17, handwheel 16, screw rod 5 and positioning unit 18 assemblies constitute, wherein pedestal 10 is an ironcasting, on the branch, lower semi-body, lower semi-body is installed in the special-purpose locating hole of upper semi-body, and be designed to a through hole in the middle of the upper semi-body, mounting core axle unit 17 in the through hole, mandrel unit 17 is by mandrel 6, counterdie 15, patrix 14, bearing 8, bearing gland 7, pad c9, pad a3, pad b4 and nut 2 constitute, and on mandrel 6, being arranged in order installation from right to left, retainer to be processed is fixed between the patrix 14 and counterdie 15 of screw rod 5 left ends; The long bolt 5 of TOE passes mandrel 6 catcher wheels 16 in parallel, and mandrel 6 is fixed on the pedestal 10 by the bearing 8 at two ends; Positioning unit 18 is made of two parts, a part is mounted in the index dial 1 on the mandrel 6, index dial 1 is installed between the pad b4 and pad a3 on the mandrel 6, and another part is the backstay 11 installed in pedestal 10 lower semi-bodies with index dial 1 lower end correspondence position, holds out against nut 12 and spring 13.
The particular manufacturing craft that is used for processing bearing retainer pocket of the present invention, its positioning unit 18 is mainly by index dial 1, backstay 11, spring 13 with hold out against nut 12 and constitute, wherein index dial 1 is installed between the pad b4 and pad a3 on the mandrel 6, and pad c9 is near pad a3 right-hand member and hold out against bearing 8 inner rings; Spring 13 is contained in the special-purpose locating hole on pedestal 10 lower semi-bodies, and backstay 11 passes spring 13 and is screwed in the terminal holddown spring 13 of backstay 11 by holding out against nut 12; Index dial 1 and retainer coupling to be processed.
