the utility model provides a two-way self-centering clamping device of valves lathe hydraulic pressure which the key lies in: the clamping device comprises a base plate, wherein at least two positioning pins are arranged at the center of the base plate, mounting grooves are formed in the left side and the right side of the base plate respectively, a pressing embedded claw is arranged in each mounting groove, the pressing embedded claws on the two sides are arranged oppositely, the lower end of each pressing embedded claw is connected with a hydraulic chuck of a machine tool, and a pressing step is formed on each pressing embedded claw.
Further, the bottom plate is of a disc-shaped structure.
Furthermore, the positioning pins are respectively arranged on two sides of the central axis of the two lateral pressing and embedding claws, and at least one positioning pin is arranged close to the central axis of the two lateral pressing and embedding claws.
Furthermore, a supporting step is formed at the bottom of the pressing and embedding claw and movably supported on the mounting groove.
Furthermore, the front side of the bottom plate is also provided with a counterweight column.
The utility model discloses a show the effect and be:
1. the valve block is simple in structure and easy to realize, the power source is from a hydraulic chuck by adopting the extension design of the machine tool structure, the pressing embedded claws on two sides move away from or close to the center, and further, the valve block is clamped and fixed quickly by self-centering, so that the phenomenon that the traditional mode uses appearance positioning to have larger positioning processing errors is avoided, and the product processing precision is ensured;
2. the automatic clamping structure is adopted, the product is compressed, the operation is convenient, the clamping efficiency is high, and the processing efficiency is favorably improved;
3. the modular clasping mechanism is adopted, so that valve group valves which adapt to different specifications can be replaced;
4. through the arrangement of the counterweight column, the gravity center of the whole clamping device is on the central line of the bottom plate, so that the phenomenon of shaking during machining can be avoided, and the machining precision of a product is further ensured.

Detailed Description
The following provides a more detailed description of the embodiments and the operation of the present invention with reference to the accompanying drawings.
As shown in fig. 2-5, a hydraulic bidirectional self-centering clamping device for a valve group lathe comprises a disk-shaped base plate 1, at least two positioning pins 2 are arranged at the center of the base plate 1, a mounting groove 3 is respectively formed in each of the left side and the right side of the base plate 1, a pressing embedded claw 4 for clamping and fixing the left side and the right side of a product to be processed is arranged in each mounting groove 3, the pressing embedded claws 4 on the two sides are arranged oppositely, the lower end of each pressing embedded claw 4 is connected with a hydraulic chuck S of a machine tool, a pressing step 5 for pressing and fixing the upper side of the product to be processed is formed on each pressing embedded claw 4, and a counterweight column 6 is further arranged on the front side of the base plate 1. Through the arrangement of the counterweight column 6, the gravity center of the whole clamping device is on the central line of the bottom plate 1, so that the phenomenon of shaking during processing can be avoided, and the processing precision of a product is further ensured.
In this example, the positioning pins 2 are respectively arranged at two sides of the central axis of the two side pressing and embedding claws 4, and at least one of the positioning pins 2 is arranged close to the central axis of the two side pressing and embedding claws 4, so that the positioning is more accurate, and the processing precision is higher.
Preferably, a supporting step 7 is formed at the bottom of the pressing insert claw 4, and the supporting step 7 is movably supported on the mounting groove 3.
During production, the corresponding pressing embedded claws 4 are selected according to the specification of the valve group valve body to be produced, then the valve group valve body to be produced is fixed on a hydraulic chuck S of a machine tool, then the valve group valve body to be produced is accurately positioned by the positioning pins 2, then the hydraulic chuck S is driven to drive the pressing embedded claws 4 on two sides to move towards the center, finally the valve group valve body to be produced is clamped and fixed under the matching of the pressing step 5, and after clamping, the valve group valve body to be produced can be subjected to thread machining by referring to an attached drawing 6. According to the clamping device, the extension design of a machine tool structure is adopted, a power source is from a hydraulic chuck S, the pressing embedded claws 4 on two sides move away from or close to the center, so that the valve body of the valve group is clamped and fixed quickly in a self-centering manner, the phenomenon that the shape positioning in the traditional mode has large positioning and processing errors is avoided, and the product processing precision is guaranteed; the automatic clamping structure is adopted, the product is compressed, the operation is convenient, the clamping efficiency is high, and the processing efficiency is favorably improved; the modular clasping mechanism is adopted, so that valve group valves suitable for different specifications can be replaced.
