Description
Technical field
The utility model relates to a kind of eccentric shaft processing tools, belong to mechanical engineering processing tool field.
Background technique
The outer circle workpiece without coincidence parallel with the axis of outer circle, referred to as eccentric shaft.Eccentric shaft is generally by eccentric orfice
It is fixed on electric machine rotational axis, in electric motor starting, do cam movement, therefore be widely used in automobile, engine, pump etc..It is general
The part coaxial with lathe is generally processed on logical numerically controlled lathe, therefore the difficult point of eccentric shaft work in-process is accurate clamping, guaranteed
Eccentricity, centre numerically controlled lathe are common to need to treat by clamping tools such as scroll chuck, chucks when processing eccentric shaft
Processing eccentric shaft positioned, wherein when chuck gets on the bus eccentric work piece, first will workpiece mark an off-centre operation and
Guarantee cross hairs both horizontally and vertically, its position in chuck is determined according to these lines；It is made by oneself in three-jaw
When heart chuck processes eccentric work piece, a upper gasket is padded on a pawl wherein, so that workpiece is generated bias and carrys out turning.Obviously, using existing
Some methods, processing efficiency is lower, inconvenient for operation, and operating personnel needs that number plenty of time and labour is spent to adjust location eccentricity
The position of axis, mismachining tolerance is big, and processing efficiency is low, and processing cost is high.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of this eccentric shaft processing tools, can overcome the prior art
Deficiency.
In order to solve the above technical problems, the utility model is achieved through the following technical solutions: a kind of eccentric shaft processing
Tooling, it is used for the Set and Positioning of eccentric shaft, and including the fixing seat cooperated with lathe chuck, the fixing seat is and lathe chuck
The disk of coaxial arrangement offers sliding slot in fixing seat, and sliding slot is interior to be fixed with eccentric shaft clamping device by adjusting screw.
The size scale of measurement eccentricity, and the zero graduation line of size scale are equipped with beside the sliding slot of aforementioned fixing seat
For fixing seat central axis.
Aforementioned bias shaft clamping device is elastic jacket.
It is equipped in aforementioned eccentric shaft clamping device excircle axial location corresponding with the measurement size scale of eccentricity
Measurement markers.
Compared with the prior art, the utility model discloses a kind of eccentric shaft processing tools comprising matches with lathe chuck
The fixing seat of conjunction offers sliding slot in fixing seat, and sliding slot is interior to be fixed with eccentric shaft clamping device by adjusting screw, processes
When, it by fixing seat clamping on lathe, is connected in eccentric shaft clamping device at fixing seat central axis, eccentric shaft clamping is existed
On eccentric shaft clamping device, one end of eccentric shaft is processed, completes the process section with eccentric shaft gripping means grips again after taking-up, is grasped
Making adjustments screw makes eccentric shaft clamping device be moved to eccentric distance, carries out the processing of the eccentric shaft other end, it is preferable that by sliding slot
Side is equipped with the size scale of measurement eccentricity, and staff is referred to size scale and is adjusted, and can quickly regulate partially
The eccentricity of mandrel processing, it is convenient to use.
The utility model structure is simple, and flexible adjustment is high, easy to use, can greatly save manpower and time, and
It can effectively improve the machining accuracy and processing efficiency of eccentric shaft, practical, generalization is high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the right side structural schematic diagram of Fig. 1.
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:
As depicted in figs. 1 and 2, a kind of eccentric shaft processing tool, it be used for eccentric shaft Set and Positioning, including with lathe card
The fixing seat 1 of disk cooperation, the fixing seat 1 is the disk being coaxially disposed with lathe chuck, offers sliding slot in fixing seat 1
11, sliding slot 11 is interior to be fixed with eccentric shaft clamping device 2 by adjusting screw 3, and the bias shaft clamping device 2 is elastic jacket.
When processing, by 1 clamping of fixing seat on lathe, it is coaxially disposed eccentric shaft clamping device 2 with lathe chuck, processes eccentric shaft
One end, clamped again after taking-up and complete the process section, by adjust screw 3 so that eccentric shaft clamping device 2 is moved to eccentric distance, into
The processing of the row eccentric shaft other end.
The size scale 4 of measurement eccentricity, and the zero of size scale 4 are equipped with beside the sliding slot 11 of the fixing seat 1
Graduation mark is fixing seat central axis.It is equipped with and measurement eccentricity in the eccentric 2 excircle axial location of shaft clamping device
The corresponding measurement markers 22 of size scale 4 when measurement, are aligned the graduation mark of size scale 4 with measurement markers 22, more just
Just eccentricity size is read, eccentricity size can be effectively ensured, reduces mismachining tolerance.
