Description
Technical Field
The utility model relates to a numerical control field clamping device, in particular to change table presss from both sides tight hydro-cylinder device.
Background
In order to improve the processing efficiency of the numerical control boring and milling machine, an automatic exchangeable workbench is often arranged on a machine tool, so that the cutting processing and the auxiliary loading and unloading of workpieces are synchronously carried out, and the clamping and the releasing of the workbench are very important because the workbench needs to be exchanged continuously: the clamping is used for ensuring the machining precision of the workpiece, and the loosening is used for ensuring that the workbench can be smoothly exchanged.
At present, a butterfly spring and clamping oil cylinder combined clamping device is mainly adopted for clamping a working table at home and abroad, and the device is widely applied due to stable and reliable performance, compact structure and low manufacturing cost. However, when the load is large, the contact area between the worktable and the clamping device is small, so that the worktable is easy to deform under the action of heavy load, and the overall accuracy of the machine tool is affected.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a change table clamping cylinder device which is convenient to assemble and improves precision.
The utility model provides a change table presss from both sides tight hydro-cylinder device, connect and the spring including piston, piston flange, the tight seat of clamp, supporting shoe, hydraulic oil, the piston has the piston flange, be equipped with the space between piston and the piston flange, piston upper portion cavity, the piston is connected with the tight seat of clamp, be equipped with the supporting shoe on the tight seat of clamp, it connects still to be equipped with hydraulic oil in the tight seat of clamp, the piston is equipped with the spring with pressing from both sides between the tight seat of clamp, it connects and is connected the space with hydraulic oil to be equipped with oil sweetgum fruit way in the tight seat of clamp.
In the scheme, a gasket is arranged between the clamping seat and the supporting block.
In the above scheme, the spring is a disc spring.
In the above scheme, a first sealing ring is arranged between the piston and the clamping seat.
In the scheme, a second sealing ring is arranged between the piston flange and the clamping seat.
The utility model has the advantages and the beneficial effects that: the utility model provides a make things convenient for assembly, the change table clamping cylinder device of improving precision. This device has increased the supporting shoe on traditional clamping mechanism basis in order to increase workstation and clamping device's area of contact, makes the workstation can not produce the deformation because of the effect of heavily loaded, has improved the machining precision of lathe. The device increases the adjustment link and reduces the difficulty of assembly and processing.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. piston 2, piston flange 3, clamping seat 4 and supporting block
5. Hydraulic oil joint 6, spring 7, oil path channel 8 and gasket

Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the utility model relates to an exchange workbench presss from both sides tight hydro-cylinder device, including piston 1, piston flange 2, press from both sides tight seat 3, supporting shoe 4, hydraulic oil joint 5 and spring 6, piston 1 has piston flange 2, is equipped with the space between piston 1 and the piston flange 2, piston 1 upper portion cavity, piston 1 with press from both sides tight seat 3 and be connected, press from both sides to be equipped with supporting shoe 4 on the tight seat 3, still be equipped with hydraulic oil joint 5 in pressing from both sides tight seat 3, piston 1 and press from both sides and be equipped with spring 6 between the tight seat 3, press from both sides to be equipped with oil sweetgum fruit way 7 in the tight seat 3.
A gasket 8 is arranged between the clamping seat 3 and the supporting block 4.
The spring 6 is a disc spring. A first sealing ring 9 is arranged between the piston 1 and the clamping seat 3. A second sealing ring 10 is arranged between the piston flange 2 and the clamping seat 3.
The upper part of the piston 1 is hollow and can be placed into an exchange table working guide rail which is connected with a working table at the upper part, when in clamping operation, the working table enables the piston 1 to move downwards through self weight and pressure of a disc spring, so that the working table is tightly pressed on the supporting block 4, and the thickness of the gasket 8 is adjusted to enable the working table to be only contacted with the supporting block 4 but not contacted with the exchange table guide rail; when the operation is loosened, pressure oil is injected through the hydraulic oil joint 5, the piston 1 moves upwards under the action of the pressure oil, the workbench is separated from the supporting block 4, and the workbench is supported by the guide rail of the exchange workbench at the moment, so that the exchange operation of the workbench can be carried out. The device has increased the supporting shoe on traditional clamping mechanism basis in order to increase workstation and clamping device's area of contact, makes the workstation can not produce the deformation because of the effect of heavily loaded, has improved the machining precision of lathe. In addition, the clamping device increases the adjusting link and reduces the difficulty of assembly and processing.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
