The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of simple in structure and clamping device cleverly is provided, and it can exchange plate and adapt to different carburetors by changing, thereby reliably firmly clamps carburetor, and quick and easy.
In order to achieve the above object, the utility model can be by the following technical solutions:
A kind of carburetor clamping device comprises:
One frame, it comprises that a base and a level frame be located at the gripper shoe of base top;
One exchanges plate, and level is installed on the base replaceably;
One is used for the location-plate of positioning workpieces, its removably level be installed on and exchange on the plate; And
One is used for holding down assembly of workpiece pressing, and its corresponding location-plate is fixed on the gripper shoe.
As preferably, described location-plate, exchange plate and base connects the location by bearing pin mutually.
As preferably, described location-plate, exchange plate and base is respectively arranged with a pinhole in the left and right sides separately mutually accordingly, the pinhole of homonymy is interconnected and inserts bearing pin.
As preferably, described exchange plate, location-plate are fixedly connected on base by screw.
As preferably, described location-plate, four angle ends that exchange plate are respectively arranged with a fixed via, are respectively arranged with a retaining thread hole on the corresponding part of four angle extreme directions of described base; Be interconnected and screw in screw with the fixed via of angle extreme direction and retaining thread hole.
As preferably, corresponding workpiece setting has the identical location key seat of quantity and alignment pin on the described location-plate, and some locating dowels.
As preferably, described location key seat and alignment pin are respectively arranged with two, and are provided with a locating dowel.
As preferably, described alignment pin is respectively cylindrical positioning pins and diamond positioning pin, and described location key seat is circular location key seat and diamond positioning pin seat.
As preferably, described holding down assembly comprises the cylinder that is fixedly installed on the gripper shoe, and the pressure head that the corresponding location-plate with of the piston rod of described cylinder arranges connects.
Compared with prior art, the utlity model has following beneficial effect:
By changing the exchange plate of different-thickness, can adapt to different carburetors, thereby reliably firmly clamp carburetor, and quick and easy; And the pinhole on location-plate, exchange plate and the base and the cooperation of bearing pin can position the three, when changing the exchange plate, have guaranteed that the relative position of location-plate and base is constant.
The specific embodiment
As shown in Figures 1 to 3, carburetor clamping device described in the utility model comprises frame, and described frame comprises base 11, support column 12 and is located at the gripper shoe 13 of base 11 tops by support column 12 level frames.Level is installed a removable exchange plate 4 on base 11, and level is installed a detachable location-plate 3 for positioning workpieces on the exchange plate 4.Location-plate 3, exchange plate 4 and base 11 left and right sides separately are respectively arranged with a pinhole, and the pinhole of homonymy is interconnected, and insert bearing pin; Under the effect of pinhole and bearing pin, can position the three, and guarantee to change when exchanging plate 4, location-plate 3 is with respect to the invariant position of base 11.Four angle ends of location-plate 3, exchange plate 4 are respectively arranged with a fixed via, and are respectively arranged with a retaining thread hole in the corresponding part of 11 4 angle extreme directions of base; Fixed via and retaining thread hole with the angle extreme direction are interconnected, and screw in screw; Location-plate 3, exchange plate 4 are fixed on the base 11 by thread connection.Corresponding workpiece setting has two location key seats 31 and two alignment pins 32 on location-plate 3, and is provided with a locating dowel 33; Come positioning workpieces by alignment pin 32 and locating dowel 33; Described alignment pin is respectively cylindrical positioning pins and diamond positioning pin, and corresponding location key seat is circular location key seat and diamond positioning pin seat.
Exchanging plate 3 can change according to the demand of workpiece, and the thickness of different exchange plates 3 is different, usually selects the exchange plate of suitable thickness to the height of locating surface according to center, carburetor throat hole.
As shown in Figure 1, be installed with a cylinder 21 in gripper shoe 13, the pressure head 22 that the corresponding location-plate 3 with of the piston rod of cylinder 21 arranges connects.
During clamping, first workpiece is installed on the location-plate, then cylinder band dynamic head moves downward workpiece pressing, can start lathe workpiece is processed; When changing workpiece, only need to exchange plate by the demand replacing, can carry out next time clamping and processing, both simply also convenient, and do not affect precision.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and change.
