Axial line overlaps.Bit-avoiding slot carries out processing drill to keep away position, and drill bit is contacted with pedestal and damaged when preventing drilling.
Preferably, mounting hole is offered on the fixed part, and fishbolt, the clamping spiral shell are connected in the mounting hole
Bolt is by the Workpiece clamping on the fixed part.
Preferably, locating slot is offered on the fixed part.
Further, the locating slot includes the first locating slot for being opened in the fixed part surface, is opened in described
The second locating slot in a positioning groove, first locating slot, the second locating slot center line and the fixed part center line
It overlaps.
Preferably, the fixed part is wholely set with support portion.
Preferably, the putting groove is open slot.Convenient for workpiece of putting and take, processing efficiency is improved.
Preferably, the pedestal is cylinder.The rotational axis line of pedestal is overlapped with center line.
Due to the application of the above technical scheme, the utility model has following advantages compared with prior art：This practicality is new
A kind of eccentric tooling of type, the rotational axis line of pedestal is being overlapped with the axial line of lathe rotary table, while passing through clamping
Workpiece to be processed is accurately positioned in bolt and positioning column, ensures the machining accuracy to workpiece to be processed.Meanwhile putting groove is
Open slot improves processing efficiency convenient for workpiece of putting and take.This bias Fixture Design is reasonable, and installation is simple, easy to use.

Specific implementation mode
The technical solution of the utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
Referring to attached workpiece shown in FIG. 1 comprising workpiece body 1, is opened in the working position 2 in workpiece body 1
Location hole 3 in workpiece body 1.In process of production, it needs to open up through-hole 21 and blind hole 22 in working position 2.And through-hole 21
It is overlapped with the center line of blind hole 22.
If attached drawing 2 is to attached eccentric tooling shown in Fig. 4, it is used for clamping workpiece, and drive workpiece with the rotation of eccentric tooling
Axle center is rotated, in order to drill to workpiece.This bias tooling includes pedestal 4, is opened in 4 surface of pedestal for putting
The putting groove 5 of workpiece, is used to support workpiece at the fixed part 6 for being used to fix workpiece in putting groove 5 in putting groove 5
The support portion 7 of working position 2.Eccentric tooling further includes the positioning region 8 being set in putting groove 5, is used to wear on positioning region 8
Cross the positioning column of workpiece upper Positioning holes 3.The center line of support portion 7 is overlapped with the rotational axis line of pedestal 4.Preferably, pedestal 4 is in
Cylinder, rotational axis line are its center line.Positioning region 8 is wholely set with fixed part 6.
Bit-avoiding slot 71 is offered on support portion 7, the center line of bit-avoiding slot 71 is overlapped with the rotational axis line of pedestal 4.Keep away position
Slot 71 avoids drill bit from being in contact with pedestal 4 and damages for keeping away position to drill bit.
Mounting hole 61 is offered on fixed part 6, and fishbolt is connected in mounting hole 61.Fishbolt is used for workpiece clamp
