Abstract
The utility model relates to a separate type dividing apparatus for a worktable of an oil cylinder of a combined machine tool, which is composed of a two separate double-action linear type oil cylinders [namely, a lifting oil cylinder (7) and a return oil cylinder (22) ], an engaging and disengaging fluted disc (2), a shifting disc (1), a connecting barrel (3), a connecting sleeve (4), a core axle (11), a safety positioning pin (10), an auxiliary positioning disc (14), a supporting axle (16) and a stroke adjusting screw (23). The utility model is a separate linear double-action dividing apparatus for an oil cylinder type return worktable, which is provided with a displacement safety device and a damping device.
Description
The utility model relates to a kind of building-block machine discrete oil cylinder rotary table indexing means, and it comprises discrete cylinder system; Clutch fluted disc indexing system; Buffer system; The dislocation insurance system.
In existing hydraulic-driven rotary table circular index mode, mostly adopt hydraulic jack tooth bar and meshed transmission gear mode, realize the calibration of workbench, require the part accuracy of manufacture higher when installing, so require to have the high accuracy process equipment owing to this structure; The rack-and-pinion engagement produces radial pressure during use, wearing and tearing easily; Use the back to be difficult for changing consumable accessorys such as seal; Sub-degree angle mostly is fixed value, and the conversion sub-degree angle needs to change oil cylinder; Unprotect measure during dislocation.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of simple in structure, uses reliably, makes easily and installs, and is convenient to maintenance, arbitrarily adjusts sub-degree angle; And has a discrete straight line two-way cylinder formula rotary table indexing means of dislocation safeties and buffer unit.
The purpose of this utility model can reach by following measure: (seeing accompanying drawing)
Oil cylinder (7) is lifted in a discrete vertical installation, and adapter sleeve (4) the T type groove that is connected with rotary table mandrel (11) connecting cylinder (3) by piston (6) T type termination links to each other, and locks with nut (5).Another discrete level installation revolution oil cylinder piston (21) is located fluted disc (12) number of teeth equal dial (1) with the number of teeth with end face by bearing pin (8) and is linked to each other, angling cylinder (22) is placed in can be around the back shaft (16) of vertical oil cylinder axis rotation, bearing (15), on the supporting seat (17), with adjusting nut (18) adjustment and fixing, when angling cylinder piston (21) promotes the revolution of dial (1) drive rotary disk calibration, angling cylinder (22) will be swung around its back shaft (16) axis, (swing up 6 degree when calibration 60 is spent, other minute of angle: 45 degree, 36 degree, 30 degree, 24 degree swings reduce successively).
The utility model embodiment in conjunction with the accompanying drawings is described in further detail:
In Fig. 1 and Fig. 2, discrete straight line double-acting type oil cylinder circular index device has been described.Lift oil cylinder (7) in workbench mandrel (11) adapter sleeve (4) below positioned vertical, piston (6) T shape termination links to each other with adapter sleeve (4) T-slot and locks with nut (5).On the back shaft (16) of its swing, piston (21) termination joins by bearing pin (8) and dial (1) journal stirrup that can freely rotate in supporting seat (17) in angling cylinder (22) horizontal setting.
Fig. 1 has also described mechanical safety, go up assist location dish (14) and be fixed on rotary disk (13) alignment pin (10) of insuring and formed by being fixed on work stage body (9), when dislocation, the insurance alignment pin can not enter in the locating hole of assist location dish (14), and rotary disk (13) can not fall.
Fig. 3 is a work table rotation oil cylinder profile, and having described that angling cylinder (22) is placed in can be on the back shaft (16) of vertical its axis, and pistons end links to each other with dial (1) journal stirrup by bearing pin (8).
Regulate or change the length of stroke adjustmenting screw (23), can change the stroke of piston (21), thereby arbitrarily change sub-degree angle.
The cone screw (20) on the adjusting cylinder cover (19) and the aperture in hole, the speed that cushions in the time of can regulating work table rotation to terminal point is avoided inertia impact, damages bearing pin (8).
Fig. 4 has described discrete straight line oil cylinder rotary table operating principle.
The rotary table operation program:
The drawing of accompanying drawing is described as follows:

The utility model has the following advantages compared to existing technology:
1. simple in structure, make easily cost is installed.
2. circular index device change calibration is convenient, flexibly.
3. easy to maintenance, safe and reliable.
