Abstract
The utility model discloses a fixture for clamping irregular long round parts, which comprises a bottom plate, a fixed rack and an automatic centering clamping assembly as well as a coaxial locating assembly. According to the technical scheme of the utility model, the fixture has the automatic centering clamping assembly, so the parts can be easily clamped without deformation and also can be repeatedly located with high accuracy.
Description
Technical field
The utility model relates to the anchor clamps field, particularly relates to irregular oval the anchor clamps of a kind of clamping.
Background technology
Scroll chuck is to utilize moving radially of three movable jaws being distributed on the chuck body, clamps workpiece and the machine tool accessories of location.As shown in Figure 1, scroll chuck specifically is made up of chuck body 61, movable jaw 62 and claw driving mechanism 63.On the scroll chuck three claws 62 below have screw thread to be meshed with the flat thread at dish-shaped bevel gear 631 back sides; When rotating cone pinion 633 through cubic hole 632 with spanner; Dish gear 631 rotates; The flat thread at the back side drive simultaneously three claws 62 to the center near or withdraw from, in order to clamp the workpiece of different-diameter.Be used in and change three anti-pawls on three claws, be used for installing the bigger workpiece of diameter.The accuracy of centering voluntarily of scroll chuck is 0.05-0.15mm.
But during with irregular oval of scroll chuck clamping, irregular oval can only an end clamping, the other end is sagging easily; Be easy to generate off-centre during rotation, be not easy to clamp, and be that clampings is when needing the increase clamping force; Make workpiece deformation again easily, make that the clamping rigidity of workpiece is not enough.In addition, the repetitive positioning accuracy of workpiece is not high, and it is difficult to proofread and correct.
The utility model content
The utility model aims to provide a kind of easy clamping, does not make workpiece deformation, the anchor clamps that the clamping that repetitive positioning accuracy is high is irregular oval.
To achieve these goals, the utility model provides a kind of clamping irregular oval anchor clamps, comprising: base plate, fixed mount and self-centering clamp assembly and coaxial positioning assembly.
Further, the self-centering clamp assembly comprises: two scroll chucks and be supported on two cushion blocks between the scroll chuck, backplanes support is positioned at a following scroll chuck.
Further, the coaxial positioning assembly comprises: the centering bar is installed on the base plate with location tapered sleeve, location tapered sleeve, and insert in the tapered sleeve of location the lower end of centering bar.
Further, the lower end of centering bar has the Mohs 5# awl that matches with the location tapered sleeve.
Further, fixed mount comprises: push rod, double threaded screw and rectangular pressing plate, and push rod and double threaded screw are separately fixed on the base plate, and rectangular pressing plate middle part is screwed on the double threaded screw, and an end props up push rod, and the other end compresses and is positioned at top scroll chuck.
Further, push rod, double threaded screw and rectangular pressing plate are respectively three, and double threaded screw and push rod are distributed on the concentric internal and external circumference of base plate upper face.
According to the technical scheme of the utility model, because these anchor clamps have the self-centering clamp assembly, can realize light clamping, do not make workpiece deformation simultaneously, all right resetting, precision is very high.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of the specific embodiment.
Shown in Fig. 2 a and 2b, the anchor clamps that this clamping is irregular oval comprise: base plate 1, fixed mount 2 and self-centering clamp assembly 3 and the coaxial positioning assembly 4 that guarantees these self-centering clamp assembly 3 clamping accuracy.Wherein, shown in Fig. 3 a and 3b, base plate 1 is a rectangular plate shape; Right ends has two permanent opening grooves of vertically arranging 11; The plate mask has three screwed holes 12 and 13, three screwed holes 12 of three screwed holes and three screwed holes 13 to be distributed on respectively on concentric two circumference, and corresponding two screwed holes 12 and 13 on two circumference are positioned at this two circumference radially simultaneously; In addition, the circle centre position at these concentric two circumference offers tapered sleeve installing hole 14; Fixed mount 2 comprises: three push rods 21 (as shown in Figure 4), three double threaded screws (as shown in Figure 5) 22 and three block length bar pressing plates 23 (shown in Fig. 6 a and 6b), and the bottom of three push rods 21 has screw thread, and the middle part of three block length bar pressing plates 23 has screwed hole 231; Self-centering clamp assembly 3 comprises: two scroll chucks 31 and two cushion blocks 32; Coaxial positioning assembly 4 comprises: centering bar 41 (as shown in Figure 7) and location tapered sleeve 42 (as shown in Figure 8), the lower end of centering bar 41 have the Mohs 5# awl that matches with location tapered sleeve 42.
During debugging clamper, be installed to base plate 1 on the workbench (not shown) of lathe through permanent opening groove 11 earlier, will locate tapered sleeve 42 and be installed in the tapered sleeve installing hole 14; Again a scroll chuck 31 is placed into the top of location tapered sleeve 42, then two cushion blocks 32 is filled up on this scroll chuck 31, another scroll chuck 31 is installed on two cushion blocks 32; Then, three double threaded screws 22 and three push rods 21 are screwed in respectively in the screwed hole 12 and 13 on inside and outside two circumference of base plate 1, again three block length bar pressing plates 23 are screwed in three double threaded screws 22 respectively; Make an end of rectangular pressing plate 23 prop up push rod 21; The other end compresses the upper surface of a top scroll chuck 31, and at this moment, the bar 41 of will feeling relieved inserts in the tapered sleeve 42 of location; Again with two scroll chucks, 31 difference Centering Clamping bars 41; Make that two scroll chucks 31 are coaxial, adjust the height of three push rods 21, three double threaded screws 22 and three block length bar pressing plates 23 this moment again, make a top scroll chuck 31 push against a cushion block 32 and a following scroll chuck 31; And the maintenance level, the nut that tightens double threaded screw 22 is at last fixed.Unclamp two scroll chucks, 31 taking-up centering bars 41 again, add man-hour, only need clamping workpiece to two a to be processed scroll chuck 31 just can be realized light clamping, do not make workpiece deformation simultaneously, all right resetting, precision is very high.
The utility model irregular workpiece such as engine that can be used to sling.More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
