SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the technical problems that a traditional one-way tensioning workbench is prone to failure and difficult to maintain are solved.
The utility model provides a hydraulic clamping device of a rotary table, which comprises a base and a workbench, and also comprises a plurality of uniformly distributed oil cylinders and elastic components, wherein the oil cylinders drive the workbench to realize the compaction of the workbench and the base; the elastic component drives the workbench to realize that the workbench and the base are loosened.
The hydro-cylinder drive control workstation compresses tightly, and elastic component is in compression state, when the workstation need loosen, stops the hydro-cylinder fuel feeding, and elastic component's restoring force orders about the workstation and loosens, the utility model discloses simplified the control link, simple structure, stability is strong, has not only avoided the production of trouble, and it is also more convenient to maintain moreover.
Further, the oil cylinder is only provided with one oil port. Because the oil cylinder only needs one action and one oil port, the manufacturing cost of the oil cylinder is saved.
Furthermore, the elastic assembly comprises a clamping mechanism seat fixedly connected with the base, the clamping mechanism seat is connected with a spring seat through a first spring, and the spring seat is connected with the oil cylinder body through a second spring. When the workbench needs to be clamped, oil is supplied to the oil cylinder, the piston rod moves downwards and applies pressure to the workbench, the cylinder body of the oil cylinder moves upwards under the reaction force of the piston rod and clamps the workbench, at the moment, the spring seat moves upwards along with the cylinder body of the oil cylinder, and the first spring and the second spring are in a compressed state; when the workbench needs to be loosened, oil supply of the oil cylinder is stopped, and restoring forces of the first spring and the second spring drive the oil cylinder and the spring seat to reset; so design, simple structure is reliable.
The oil cylinder body is connected with the workbench through a clamping block, and the connecting surfaces of the oil cylinder body and the clamping block are respectively designed into a conical surface and a spherical surface which are matched. So set up, press from both sides tight piece and can incline, be convenient for press from both sides tight piece and the laminating of workstation bottom, stability when improving the workstation and press from both sides tightly.
Furthermore, the workbench is provided with an annular groove, and the piston rod of the oil cylinder penetrates through the annular groove and is clamped with the annular groove through a convex block arranged at the end part. The workbench is clamped in a mode that the convex block is tightly pressed on the annular groove, and when the convex block is separated from the annular groove, the workbench can smoothly rotate, and the structure is simple.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-4, the utility model relates to a hydraulic clamping device for a turntable, which comprises a base 1 and a workbench 2, and also comprises a plurality of uniformly distributed oil cylinders 3 and elastic components, wherein the oil cylinders 3 drive the workbench 2 to realize the compaction of the workbench 2 and the base 1; elastic component drive workstation 2 realizes that workstation 2 and base 1 loosen.
The oil cylinder 3 is only provided with one oil port 31, and the manufacturing cost of the oil cylinder 3 is saved due to the fact that the oil cylinder 3 only needs one action and the arrangement of the oil port 31.
The working table 2 is provided with an annular groove 21, and a piston rod of the oil cylinder 3 passes through the annular groove 21 and is clamped with the annular groove 21 through a lug 32 arranged at the end part. The worktable 2 is clamped in a mode that the lug 32 presses the annular groove 21 tightly, and when the lug 32 is separated from the annular groove 21, the worktable 2 can smoothly rotate, and the structure is simple.
The elastic assembly comprises a clamping mechanism seat 4 fixedly connected with the base 1, the clamping mechanism seat 4 is connected with a spring seat 5 through a first spring 7, and the spring seat 5 is connected with the cylinder body of the oil cylinder 3 through a second spring 8; the cylinder body of the oil cylinder 3 is connected with the workbench 2 through a clamping block 6.
