Description

The distribution ring set

Technical field

The utility model relates to the distribution ring set that a kind of air spider is used.

Background technology

The air distribution cylinder structure that existing lathe air spider is used is complicated, and volume is big, and trouble is installed.

Summary of the invention

The purpose of this utility model is to provide that a kind of structure is simpler, volume is little, distribution ring set more easily is installed, and this distribution ring set can replace the air distribution cylinder of prior art to use, and overcomes above-mentioned deficiency.

In order to achieve the above object, the technical solution of the utility model is: a kind of distribution ring set, comprise compression ring shell, compression ring joint, front end cover plate and core bar, the compression ring joint is fixedlyed connected with the compression ring shell, the front end cover plate is fixedly connected on the compression ring joint, core bar is sleeved in the gentle ring joint of compression ring shell, and core bar is by the bearings that is installed in compression ring shell and the compression ring joint, and core bar is provided with first air flue and second air flue; First air inlet is arranged on the compression ring shell, second air inlet is arranged on the front end cover plate, and communicate with first air flue and second air flue on the core bar respectively; Have the annular air inlet duct that communicates with first air inlet on the internal perisporium of compression ring shell; Between compression ring joint and the front end cover plate, and the seal sealing is arranged all between core bar and the front end cover plate.

After adopting said structure, because the state that distribution ring set of the present utility model adopts the corresponding respectively chuck of two air inlets of straight aeration type structure to clamp and unclamp, and the core bar two ends are adopted grease seal and seal sealing respectively, in working order down, core bar is difficult for seal is caused too big wearing and tearing when rotating, thereby the utility model structure is simpler, volume is little, installs also more conveniently, does not need the professional and technical personnel to finish during installation.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of Fig. 1 along the A-A direction.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

As shown in Figure 1, 2, a kind of distribution ring set, comprise compression ring shell 1, compression ring joint 2, front end cover plate 3 and core bar 4, compression ring joint 2 is fixedlyed connected with compression ring shell 1, front end cover plate 3 is fixedly connected on the compression ring joint 2, core bar 4 is sleeved in the compression ring shell 1 gentle ring joint 2, and core bar 4 is supported by the bearing 5 that is installed in compression ring shell 1 and the compression ring joint 2, and core bar 4 is provided with the first air flue 4-1 and the second air flue 4-2; The first air inlet 1-1 is arranged on the compression ring shell 1, the second air inlet 3-1 is arranged on the front end cover plate 3, and communicate with the first air flue 4-1 and the second air flue 4-2 on the core bar 4 respectively; Have the annular air inlet duct 1-1-1 that communicates with the first air inlet 1-1 on the internal perisporium of compression ring shell 1; Between compression ring joint 2 and the front end cover plate 3, and seal 6 sealings are arranged all between core bar 4 and the front end cover plate 3, effectively guaranteed to enter the pressure of distribution ring set gas.

As shown in Figure 1, 2, for better sealing, have oilhole 1-2 on the periphery wall of described compression ring shell 1; And have the annular oil groove 1-2-1 that communicates with this oilhole 1-2 on the internal perisporium of compression ring shell 1.When mandrel turned round, the oil among the annular oil groove 1-2-1 can form oil film between mandrel 4 and compression ring shell 1, both played the sealing function that prevention is leaked gas from annular air inlet duct 1-1-1, can play the lubrication that mandrel 4 turns round in compression ring shell 1 again.

As shown in Figure 1, 2, have Oil Guide on the internal perisporium of the oilhole 1-2 on the described compression ring shell 1 and prop up hole 1-2-2, and this Oil Guide props up hole 1-2-2 and communicates with bearing 5.Effective like this lubricated of bearing 5 that guaranteed.

In order to make both sides bearing 5 can both realize lubricant effect and to increase mandrel 4 and the sealing effectiveness of 2 of compression ring joints, have oilhole 2-1 on described compression ring joint 2 periphery walls; This oilhole 2-1 communicates with cavity 10 between the mandrel 4 gentle ring joints 2 that bearing 5 is housed.

As shown in Figure 2, fixedly connected by bolt 7 between described compression ring joint 2 and the compression ring shell 1.

As shown in Figure 1, 2, fix by jump ring 8 between described bearing 5 and the mandrel 4 and between bearing 5 and the compression ring shell 1; Between described bearing 5 and the jump ring 8, also be provided with pad 9; The utility model can be regulated and adapts to relative position between core bar 4 and the compression ring shell 1 by the thickness of pad 9.

As shown in Figure 1, 2, the utility model in use, as long as with distributing ring cover of the present utility model gas outlet one end, directly sealing and fixing is installed in the chuck joint, thereby installs easily, as the needs clamping work pieces, gas is from the first air inlet 1-1, enter the first air flue 4-1 of mandrel 4 through annular gas tank 1-1-1, make the first air chamber inflation that is connected in the first air flue 4-1, workpiece is clamped thereby produce pressure; Unclamp workpiece as needs, gas enters second air chamber from the second air inlet 3-1 through the second air flue 4-2 of mandrel 4, and the gas in first air chamber is discharged from the first air inlet 1-1 through the first air flue 4-1.Because the state that distribution ring set of the present utility model adopts the corresponding respectively chuck of two air inlets of straight aeration type structure to clamp and unclamp, and the core bar two ends are adopted grease seal and seal sealing respectively, in working order down, core bar is difficult for seal is caused too big wearing and tearing when rotating.Distributing ring nested structure of the present utility model is simpler simultaneously, and volume is little.
