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 ~ 5, a kind of presser type corner chuck, including disk body 1, cylinder 2 and positioning sleeve 3, the positioning sleeve 3
It is fixed on the center of disk body 1, and 3 center of positioning sleeve is provided with the accommodation groove of fixed thin-wall workpiece, the cylinder body of the cylinder 2 is mounted on
On disk body 1, and pressing plate 21 is fixed on the piston rod of cylinder 2, the cylinder 2 is axially arranged on disk body 1, the pressing plate 21 with
It axially moves with the piston rod of the cylinder 2, and cooperates with the positioning sleeve 3 and thin-wall workpiece is fixed in positioning sleeve 3, institute
It states and is additionally provided with a point gas plug 4 on disk body 1, the center for dividing gas plug 4 to be set to 1 bottom surface of disk body, for the gas
Cylinder 2 supplies.
In the above-described embodiments, the axial setting of cylinder 2 makes the pressing plate 21 on its piston rod that piston rod be followed to axially move,
Described 21 one end of pressing plate is fixed on the piston rod, and the other end extends toward 1 center position of disk body.When processing the workpiece, first by workpiece
It is fixed in the accommodation groove of positioning sleeve 3, then cylinder 2, which is shunk, makes the prominent end with positioning sleeve 3 of 21 workpiece pressing of pressing plate, positioning
Set 3 is mounted on disk body 1, can be replaced according to the shape of workpiece, in order to be applicable in the workpiece of more polytypic；Tool
Body, as shown in Fig. 2, extending to form mounting surface outward at the contact surface of positioning sleeve 3 and disk body 1, aperture is applicable on mounting surface
Screw installs positioning sleeve.It is pointed out that the installation of positioning sleeve 3 in the present embodiment using the installation side of screw
Formula, according to different needs, positioning sleeve 3 may be set to be the mode of spiral installation.Replace original craft fixed using cylinder
The mode of workpiece substantially increases fixed efficiency, saves process time, reduces the disqualification rate of work pieces process deformation,
Rapidoprint is saved, compared with prior art, processing cost is greatly decreased.
In order to further increase the applicability of presser type corner chuck in the application, the cylinder 2 is corner cylinder, works as cylinder
When 2 piston rod stretches out, the pressing plate 21 rotates outward close to the one end at disk body center, when the retraction of the piston rod of cylinder 2, institute
It states pressing plate 21 and returns to home position.Corner cylinder is the prior art, and the orientation spacing rotation when piston rod stretches may be implemented
Function repeats no more, and in the biggish workpiece of some end sizes of processing, such as the caliber of flange has been welded in one end, due to method
Blue size is larger, can lead to not workpiece being embedded in positioning since the distance between pressing plate 21 and positioning sleeve 3 are too small during installation
Situation in set 3, of course for this problem is solved, the application uses the technical solution that pressing plate 21 is detachably installed, specifically
Be detailed in Fig. 2, however this scheme takes a long time, it is not necessary that when do not use generally, using corner cylinder driving pressing plate 21 technology
Scheme, can be when the piston rod of corner cylinder stretches out forward, and piston rod rotation is revolved with dynamic pressure plate 21 close to the one end at disk body center
Turn, so that, when corner cylinder is shunk, one end rotation return of the opening of pressing plate 21 is then to work to needing nested workpiece to step down
Part is pressed, and this set greatly improves the clamping efficiency to abnormal workpieces.It is pointed out that the present embodiment
Attached drawing in use 3 corner cylinders technical solution, in practical applications, as long as use this clamp structure, corner
The number of cylinder both falls within the protection scope of the utility model greater than 2.
Since chuck needs to rotate, the air pump that conventional cylinder needs both direction when in use is connected, however due to
Chuck needs to rotate, and the too many external pipeline of setting can make chuck that can not rotate, in this application, it is described divide on gas plug 4 set
There are air inlet 41 and gas outlet 42, it is described that gas plug 4 and the contact surface of the disk body 1 is divided to be provided with annular air reservoir 43, it is described
Annular air reservoir 43 is connected by the air flue in disk body 1 with inlet channel/outlet passageway of the cylinder 2, the air inlet 41
It is connected with gas outlet 42 and annular air reservoir 43, annular 43 both ends of air reservoir are equipped with sealing structure.As shown in Fig. 2 ~ 4, point
The effect of gas plug 4 is gas collection and divides gas, and 4 bottom end of gas plug is being divided to only to be provided with two interfaces, for being connect with air pump, In
In practical application, the interface of gas plug 4 is divided to be connected to air pressure gyrator, realizes the function of ventilating in rotation.Gas plug 4 is divided to exist
There are two annular air reservoir 43, air reservoir 43 is connected prior to interface, is then in disk body 1 for the axial setting contacted with disk body 1
Air flue connection, air flue and cylinder 2 are connected, thereby realize inside disk body to the function of each cylinder 2 ventilation, divide gas certainly
It is provided with sealing structure in plug 4 and disk body 1, prevents the leakage of gas from leading to insufficient pressure to influence clamping effect.
In order to further increase the applicability of the utility model, when replacing positioning sleeve 3, when the enlarged outside diameter of positioning sleeve 3,
Inner cavity is protruded into order to not influence cutter, the end of the pressing plate 21 is equipped with guide pad 21a, and the guide pad 21a is equipped with guiding
Notch, and connect by screw with the pressing plate 21.The material of pressing plate 21 is saved by the way of replacing guide pad 21a,
Guide groove is set on guide pad 21a and is easily installed fixation.
It should be understood by those skilled in the art that the present utility model is not limited to the above embodiments, above-described embodiment and
Only illustrate the principles of the present invention described in specification, on the premise of not departing from the spirit and scope of the utility model,
The utility model also has various changes and improvements, these changes and improvements both fall within the scope of the claimed invention
It is interior.The protection scope of the present invention is defined by the appended claims and their equivalents.
