In order to achieve the above object, the technical scheme adopted by the utility model is a kind of central through hole formula corner chuck, Including disk body, the disk body end face center is axially provided with positioning sleeve, and the positioning sleeve center is equipped with accommodating through-hole, the accommodating Through-hole is provided with the corner cylinder for compressing the workpiece, the disk body is provided centrally with for placing workpiece on the disk body Ventilation plug, the ventilation plug are equipped at least one interface, and the interface is connected with the accommodating through-hole.
Further, the center of the ventilation plug other end opposite with interface is equipped with conical cavity, the conical cavity It is connected with the interface.
Further, channel is equipped in the ventilation plug, the one end of the channel is equipped with the screw thread for installing interface, separately One end is connected with the conical cavity.
Further, the axial centre in the channel is set on the inclined surface of the conical cavity.
Further, sealing structure is equipped in the contact surface of the ventilation plug and the disk body.
Further, the interface is connect with air pump and/or water pump.
Further, the positioning sleeve is removably mounted on the disk body.
Further, the ventilation plug is removably mounted on the disk body.
Further, the accommodating through-hole is stepped ramp type structure.
The utility model has the following beneficial effects: water flowing interface is arranged from disk body bottom, makes to cut by the way of central through hole Cutting water can enter from the interior hole machined of workpiece from inside, to easily cool down to machining area.Further, it cuts The notch setting of water is cut on the inclined surface of conical cavity, the cutting water of ejection can be allowed to generate stronger impact force to inner wall, just In the discharge for being attached on clast on inner wall.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments recorded in the utility model, for those of ordinary skill in the art, is not making the creative labor Under the premise of, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of central through hole formula corner chuck in the utility model;
Fig. 2 is the cross-sectional view of central through hole formula corner chuck in the utility model;
Fig. 3 is the cross-sectional view of ventilation plug in the utility model.
Appended drawing reference: 1- disk body, 2- positioning sleeve, 3- corner cylinder, 4- ventilation plug, 21- accommodate through-hole, 41- interface, 42- Conical cavity, the channel 43-.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.The utility model uses progressive writing mode.
As shown in Fig. 1 ~ 3, a kind of central through hole formula corner chuck, including disk body 1,1 end face center of disk body are axially set It is equipped with positioning sleeve 2,2 center of positioning sleeve is equipped with accommodating through-hole 21, and the accommodating through-hole 21 is for placing workpiece, the disk body The corner cylinder 3 for compressing the workpiece is provided on 1, the disk body 1 is provided centrally with ventilation plug 4, the ventilation plug 4 It is equipped at least one interface 41, the interface 41 is connected with the accommodating through-hole 21.
In the above-described embodiments, corner cylinder 3 is equipped with the pressing plate for workpiece pressing, and pressing plate and positioning sleeve 2 cooperate, will be embedding The workpiece being placed in positioning sleeve 2 compresses, and then carries out the processing operation of inside workpiece, will be cut by the interface 41 for plug 4 of ventilating The accommodating through-hole 21 for cutting water and fixed workpiece is connected, and cools down cutting water to workpiece from inside, cooling effect is more preferable.
Workpiece causes to damage when accommodating and compressing in through-hole 21 to disk body in order to prevent, and accommodating through-hole 21 is arranged to Step-edge Junction Structure, workpiece are placed on the front end of the step structure of accommodating through-hole 21, the ventilation plug 4 other end opposite with interface 41 Center is equipped with conical cavity 42, and the conical cavity 42 is connected with the interface 41.
