Description
[technical field]
The invention relates to a kind of tool, especially a kind of holding workpiece tool.
[background technology]
The clamping fixture that is applied to surface grinding machine or machining tool in the prior art is generally magnetic suction disc or vice, and its method of clamping is direct clamping.
Please refer to shown in Figure 1ly, it is for grinding the example that adopts the magnetic suction disc holding workpiece in the processing procedure, and magnetic suction disc 4 is by magnetic force fixing workpiece 5, and it is the plane that emery wheel 6 grinds with this Surface Machining with workpiece 5 on workpiece 5 surfaces.The contact-making surface of workpiece 5 and magnetic suction disc 4 is a curved surface or when having flexural deformation, magnetic suction disc can not evenly distribute to the support force of workpiece 5 in above-mentioned grinding processing procedure, thereby can cause the curvature portion of workpiece 5 to deform; After workpiece 5 was removed by the support force of the active force of emery wheel 6 and magnetic suction disc, workpiece 5 recovered deformation, and its surface that has been processed as the plane then can lose the flatness of demand.
When using the vice holding workpiece, also can be owing to vice makes that at point of application skewness on the workpiece workpiece deforms after tool is removed.
Therefore, along with modern industry goods requirement on machining accuracy is more and more higher, traditional tool and method of clamping thereof can cause workpiece deformation and can't satisfy high-precision processing request.
[summary of the invention]
In view of above-mentioned condition, be necessary to provide a kind of tool that improves the workpiece machining accuracy.
A kind of tool is used for the fixing workpiece, it is characterized in that, this tool comprises: a basal disc, a plurality of support bar and a control pressurer system; This basal disc has a cavity, and this cavity is filled with the media that flows, and the one side of this basal disc offers a plurality of through holes, and described through hole communicates with this cavity; One end of described support bar is placed in this through hole movably, and the other end stretches out in this through hole; This control pressurer system and this cavity are connected, and it controls the pressure of circulating medium in this cavity, and two relative edge's edge that this basal disc offers on the one side of these a plurality of through holes also are provided with two bearing blocks, and these a plurality of through holes are located between described two bearing blocks.
Compare existing technology, tool of the present invention adopts a plurality of support bars with the fixing workpiece, make that the described tool and the way of contact of workpiece face are that multiple spot contacts, and each support bar provides the support force of workpiece with equalization, thereby workpiece face out-of-flatness or when being curved surface, the each several part of workpiece face can obtain uniform support, can effectively avoid the distortion of workpiece with this.

[specific embodiment]
Please refer to Fig. 2, tool 1 of the present invention comprises a basal disc 12, a plurality of support bar 14 and a control pressurer system 16.
Please be simultaneously with reference to Fig. 3, basal disc 12 has a working face 120 and a cavity 126, two opposed edges are respectively equipped with two bearing blocks 124 on the working face 120, and working face 120 offers a plurality of through holes 122 between two bearing blocks 124, and these a plurality of through holes 122 communicate with cavity 126.One side of basal disc 12 also offers a passage 128, and this passage 128 joins with cavity 126, makes cavity 126 to be conducted with the external world.Wherein, be filled with a mobile media in the cavity 126, this circulating medium can be gas, also can be liquid.
In first embodiment of the invention, the circulating medium of filling in the cavity 126 is a liquid, as hydraulic oil.Control pressurer system 16 comprises hydraulic motor 160, oil pressure pipe 161 and oil pressure adjusting valve 162.One end communication passage 128 of oil pressure pipe 161, the other end is connected in hydraulic motor 160, and oil pressure adjusting valve 162 is located in the oil pressure pipe 161, its regulation and control hydraulic oil input or derivation cavity 126.By the oil pressure in hydraulic motor 160 and 162 adjustable cavities 126 of oil pressure adjusting valve.
Please refer to Fig. 4, in second embodiment of the invention, the circulating medium of filling in the cavity 126 is a gas, as compressed air.Control pressurer system 16 comprises air compressor 165, pneumatic tube 166 and air pressure regulator 167.One end interface channel 128 of pneumatic tube 166, the other end is connected in air compressor 165, and air pressure regulator 167 is located in the pneumatic tube 166, its regulation and control Compressed Gas input or derivation cavity 126.By the air pressure in air compressor 165 and 167 adjustable cavities 126 of air pressure regulator.
Please refer to Fig. 5, during holding workpiece 2, the two ends of workpiece 2 place respectively on two bearing blocks 124 of basal disc 12 tool 1 of the present invention in process, and the mid portion of workpiece 2 is supported by these support bars 14.When workpiece 2 is subjected to the downward application of force, regulate pressure to one appropriate value of circulating medium in the cavity 126 by control pressurer system 16, the height that these support bars 14 stretch out can be along with the height of the contact point of itself and workpiece 2 and is adjusted, these support bars 14 provide the support force of workpiece 2 with equalization simultaneously, make workpiece 2 can avoid because of discontinuity deformation taking place with this.
Be appreciated that ground, the described bearing block 124 of better embodiment of the present invention also can omit not.
Be appreciated that ground, basal disc 12 also can be a magnetic suction disc, and itself and these support bar 14 is used with more firm holding workpiece 2.
