Abstract
The utility model discloses a lathe tailstock end clamp block special for knurling process of shafts without center holes. A first accommodating groove is arranged at one end of the lathe tailstock end clamp block, a bearing chamber is disposed at the other end of the lathe tailstock end clamp block, a bearing is arranged in the bearing chamber, four internal-thread through holes are symmetrically arranged on the lathe tailstock end clamp block, and bottoms of the four internal-thread through holes are stopped within the first accommodating groove. The lathe tailstock end clamp block is simple in structure and convenient to use.
Description
Technical field
The utility model relates to a kind of die fixture, particularly a kind of lathe tailstock end fixture block that is exclusively used in the no centre bore shaft part annular knurl technology.
Background technology
In the engineering goods; The transmission mechanism that has need be through axle as the underloading conveying member of connections-interlock, or as the part of holding of handlebar (action bars), is the increase skin-friction force; To handle carrying out annular knurl on the circumferential surface of axle, reach the purpose of transmission power with this.
Do not have centre bore or carry out the processing of circumferential surface annular knurl for processed shaft part two ends,, be difficult to processing owing to lack the centre bore location from the shaft part that a certain major axis takes off.
When the no centre bore shaft part circumferential surface annular knurl technology of processing, employing " folder-top " technology.
In the processing, shaft part one end matches with lathe end fixture block, and clamping is on the lathe spindle chuck, and the other end matches with lathe tailstock end fixture block, and clamping is on lathe tailstock, and it is tight to pass through the lathe tailstock end pinnacle vertex of a cone, and is fixing.Like this, no central axis segment is in stable state through " folder " and " top " technology of fixture block with processed shaft part, is convenient to annular knurl processing.
The utility model content
The technical problem that the utility model will solve provides a kind of a kind of lathe tailstock end fixture block that is exclusively used in the no centre bore shaft part annular knurl technology that the shaft part that does not have centre bore is carried out the clamping location.
For achieving the above object, the technical scheme of the utility model is following:
A kind of lathe tailstock end fixture block that is exclusively used in the no centre bore shaft part annular knurl technology; One end of said lathe tailstock end fixture block is provided with first resettlement groove; The other end is provided with bearing chamber; Be provided with bearing in the said bearing chamber, symmetry is provided with the internal thread through hole that ends at the bottom of 4 holes in first resettlement groove on the said lathe tailstock end fixture block.
Preferably, the size files D1 of said first resettlement groove is than the big 0.05mm of external diameter of processed shaft part.
Preferably, the size files D2 of said bearing chamber and bearing outside diameter interference fit.
Through technique scheme, the beneficial effect of the utility model is:
The utility model is simple in structure, easy to use, integral rigidity strong, help obtaining good processing request.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Extremely shown in Figure 3 referring to Fig. 1; A kind of lathe tailstock end fixture block that is exclusively used in the no centre bore shaft part annular knurl technology of the utility model; One end of said lathe tailstock end fixture block 6 is provided with first resettlement groove 11; The other end is provided with bearing chamber 13, is provided with bearing 8 in the said bearing chamber 13, and symmetry is provided with the internal thread through hole 12 that ends at the bottom of 4 holes in first resettlement groove 11 on the said lathe tailstock end fixture block 6.
The assembly method of the utility model is following; At first; One end of lathe spindle end fixture block 2 is placed in the lathe spindle chuck 1; One end of processed shaft part 5 inserts in second resettlement groove 10, and fixing with lock-screw 7 again, the size files D3 of second resettlement groove 10 (not marking among the figure) is than the big 0.05mm of external diameter of processed shaft part 5; The other end of processed shaft part 5 inserts in first resettlement groove 11; The size files D1 of said first resettlement groove 11 is than the big 0.05mm of external diameter of processed shaft part 5; Further fixing through lock-screw 7; At last lathe tailstock end pinnacle awl 9 is withstood bearing 8, the size files D2 of said bearing chamber 13 and bearing 8 external diameter interference fit.
After accomplishing, the utility model assembling utilizing knurling tool 4 to process, the annular knurl that processes like this, and decorative pattern is even, and is no crude, and apparent mass is good.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
