Stating supporting member includes the first location division and support, and the locating part includes the second location division and limiting section, the panel
On be additionally provided be socketed with pull bar, the pull bar can support activity relatively pressing plate, the tie rod end is provided with limitation
The block piece of the press plate position.
Thus, locating core coordinates support and pressing plate limits the translation of workpiece to be added, and limiting section is used for limiting to be processed
The rotary motion of part.
As a preferred embodiment, first location division and second location division are interference fitted with the panel.
Thereby it is ensured that the stability of support and limiting section in the course of the work.
As a preferred embodiment, the panel and described connect are bolted between disk, the bolt is along panel week
To being uniformly distributed.
As a preferred embodiment, being socketed with drag link sleeve on the pull bar, the drag link sleeve part is connected to the pull bar and institute
State between panel, branch head screw is connected between the drag link sleeve and the pull bar.
Thus, it is to avoid the problem of smaller caused locating effect to pull bar of plate thickness is poor.
As a preferred embodiment, the quantity of the pull bar is two and symmetrical on the locating core.
Thereby it is ensured that pressing plate and the locating effect of support to machined part.
As a preferred embodiment, the block piece is the nut being connected with the pull rod screw.
Thus, the scope of activities of pressing plate is limited by nut, it is to avoid it departs from from pull bar.
As a preferred embodiment, the cross sectional shape of the panel for circular and diameter with described to connect dish external diameter equal.
Thus, panel is reduced with the centrifugal force during connecing disc spins.
To sum up, the utility model has advantages below：Convenient mounting and clamping, facilitates human users, improves operating efficiency；Positioning
Effect is good, it is ensured that machining accuracy.

Embodiment
The utility model is described in further detail for middle embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and shown in Fig. 3, the frock clamp includes cylinder and connects disk 2 and be fixed on the face for connecing the side of disk 2
Plate 1.Panel 1 and connecing is bolted between disk 2, and bolt is uniformly distributed along panel 1 is circumferential.In electric vacuum pump of automobile housing
Process in, connecing disk 2 can be fixed on the ring flange of numerically controlled lathe by screw connection.The middle part of panel 1 is provided with locating core
11, the sidepiece of locating core 11 is provided with supporting member 12 and locating part 13, and supporting member 12 includes the first location division 121 and support
122, locating part 13 includes the broken section that the second location division 131 is given in the second location division 131 and limiting section 132, Fig. 1
Figure.Be additionally provided with panel 1 be socketed with pull bar 3, pull bar 3 can with respect to the activity of support 122 pressing plate 32, the end of pull bar 3 is provided with
Limit the block piece 33 of the position of pressing plate 32.The centre bore that locating core 11 is passed through, support 122 is used for supporting the outer of vacuum pump case
Surface simultaneously coordinates pressing plate 32 to limit translation of the vacuum pump case along the axis direction of locating core 11, and limiting section 132 is used for preventing vacuum
Rotated during pump case Vehicle Processing.Pressing plate 32 can be via numerically controlled lathe hydraulic oil cylinder driving activity.
