Description
Technical field
The present invention relates to a kind of rotary index device, especially a kind of air-liquid rotary index device.
Background technique
Rotary indexing table is respectively provided with the rotary indexing table of so-called two head dummy of workpiece mounting surface as each machine table, can be same
When multiple workpiece are installed, shorten the time required for workpiece installation exercise, shorten the waiting time of workpiece machinery, processing is provided and is imitated
Rate.
Existing rotary indexing table, including direct drive motor, have rotor and stator, first and second machine table,
First and second machine table configures two sides and frame in direct drive motor across the direct drive motor, should
Direct-driving motor built in frame, and be that can be rotated around with the common axis of rotor by first and second processing bearing.I.e.
It is rotary indexing table is that motor-driven, this rotary indexing table error of division is big, locating effect is poor, influences work pieces process essence
Degree.
Summary of the invention
The object of the present invention is to provide a kind of indexing accuracy height, the air-liquid rotary index device of good positioning effect.
To achieve the above object, the technical scheme adopted by the invention is that：A kind of air-liquid rotary index device, including matrix,
The first airdraulic actuator and the second airdraulic actuator are equipped on matrix, first airdraulic actuator is connected with the first push rod advance gas-liquid pipe and the
One push rod retracts gas-liquid pipe, and the second airdraulic actuator is connected with the second push rod advance gas-liquid pipe and the second push rod retracts gas-liquid pipe,
Rotary shaft is equipped between one airdraulic actuator and the second airdraulic actuator, wherein the push rod of the first airdraulic actuator is equipped with inclined-plane, in certain angle
The lower inclined-plane matches on one side with rotary shaft；The push rod of second airdraulic actuator is corresponding with rotary shaft.
Preferably, the rotary shaft is set there are four plane, and corresponding two airdraulic actuator is arranged in 90 degree of angles.
Preferably, the rotary shaft is set there are six plane, and corresponding two airdraulic actuator is arranged in 60 degree of angles.
The present invention with the above structure, by the way that rotary shaft is arranged between the first airdraulic actuator and the second airdraulic actuator, wherein
The push rod of first airdraulic actuator is equipped with inclined-plane, and the inclined-plane and rotary shaft matches on one side under certain angle；Second airdraulic actuator
Push rod it is corresponding with rotary shaft.Therefore rotary shaft rotation is pushed by the second airdraulic actuator, the push rod of the first airdraulic actuator stretches out at this time,
Inclined-plane just matches with rotary shaft after rotation on one side, resists rotary shaft, and rotary shaft is avoided to rotate, good positioning effect；Pass through gas
Fluid cylinder controls rotational angle, and precision is accurate, therefore indexing accuracy is high, ensure that Workpiece Machining Accuracy.
Detailed description of the invention
Invention is further described in detail with reference to the accompanying drawings and detailed description：
Fig. 1 is that the push rod of the first airdraulic actuator of the invention stretches out the schematic diagram of state；
Fig. 2 is the schematic diagram of the push rod returns state of the first airdraulic actuator of the invention；
Fig. 3 is the connection schematic diagram of gas-liquid channel of the present invention.
In figure：1 matrix, 2 first airdraulic actuators, 21 first push rod advance gas-liquid pipes, 22 first push rods retract gas-liquid pipe, and 3
Two airdraulic actuators, 31 second push rod advance gas-liquid pipes, 32 second push rods retract gas-liquid pipe, 4 rotary shafts, 5 inclined-planes.
Specific embodiment
