Abstract
The utility model discloses a tail bracket end fixture block for an excircle grinding and two-end clamping process for a central-hole-free rotating shaft. Four internal thread through holes are symmetrically formed in the tail bracket end fixture block; an accommodating slot is formed at one end of the tail bracket end fixture block; a bearing chamber is arranged at the other end of the tail bracket end fixture block; and the internal thread through holes are communicated with the accommodating slot. The central-hole-free rotating shaft is clamped and positioned by the tail bracket end fixture block and subjected to excircle grinding processing; during processing, the processed rotating shaft is always in a stable clamped and positioned state, so that the whole rigidity is high, and a high processing requirement can be facilitated to be met; therefore, the ground excircle meets a design requirement, and has good appearance quality.
Description
Technical field
The utility model relates to the no centre bore rotating shaft cylindricalo grinding two ends clamping technology isolated plant that a kind of small and special electric machine is used, and particularly is used for not having the tailstock end fixture block of centre bore rotating shaft cylindricalo grinding two ends clamping technology.
Background technology
Existing tailstock end fixture block does not generally all have to be fixed no centre bore rotating shaft and uses in the clamping technology of centre bore rotating shaft cylindricalo grinding two ends, it is simple in structure, and fixed performance is poor.
The utility model content
The technical problem that the utility model will solve provides a kind of tailstock end fixture block that is used for fixing no centre bore rotating shaft.
For achieving the above object, the technical scheme of the utility model is following:
Be used for not having the tailstock end fixture block of centre bore rotating shaft cylindricalo grinding two ends clamping technology; Symmetry is provided with four internal thread through hole on the said tailstock end fixture block; Said tailstock end fixture block one end is provided with a resettlement groove, and the other end is provided with a bearing chamber, and said internal thread through hole communicates with said resettlement groove.
Preferably, said resettlement groove is cylindrical.
Through technique scheme, the beneficial effect of the utility model is:
The utility model will not have centre bore rotating shaft clamping location through tailstock end fixture block, carry out Cylindrical Grinding Processes.In the course of processing, processed rotating shaft is in stable clamping positioning states all the time, and integral rigidity is good, helps obtaining good processing request.
The cylindrical that comes out of grinding adheres to specification like this.Apparent mass is good.
Through general assembly, processed rotating shaft meets actual instructions for use.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the profile of the utility model tailstock end fixture block;
Fig. 2 is the utility model tailstock end fixture block and rotating shaft clamping sketch map;
Fig. 3 is the utility model tailstock end fixture block clamping sketch map.
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.
Referring to shown in Figure 1; The utility model is used for not having four internal thread through hole 2 that are provided with of symmetry on the tailstock end fixture block 1 of centre bore rotating shaft cylindricalo grinding two ends clamping technology; Said tailstock end fixture block 1 one ends are provided with a resettlement groove 3; The other end is provided with a bearing chamber 4, and said internal thread through hole 2 communicates with said resettlement groove 3, and said resettlement groove 3 is cylindrical.
To shown in Figure 3, the method for using of the utility model is following referring to Fig. 2:
One end of no centre bore rotating shaft 5 is placed in the resettlement groove 3 of said tailstock end fixture block 1; Lock-screw 6 is fixed through 2 pairs of no centre bore rotating shafts 5 of internal thread through hole; And hold out against and fix through grinding machine tailstock end pinnacle awl 8, the bearing chamber of said grinding machine tailstock end fixture block 1 one ends is provided with bearing 9.The other end of no centre bore rotating shaft 5 is placed in the resettlement groove of grinding machine spindle end fixture block 7, and it is fixing through lock-screw 6, and the end that said spindle end fixture block 7 is provided with projection 4 is connected with grinding machine spindle chuck 10.
The diameter of resettlement groove 3 is than the big 0.024-0.055mm of external diameter of processed no centre bore rotating shaft 5 on the utility model tailstock end fixture block 1.
It is 1-2mm with the distance of resettlement groove bottom surface that the utility model does not have the end face that centre bore rotating shaft 5 is placed in tailstock end fixture block 1 resettlement groove 3, and it can reduce the friction that adds rotating shaft in man-hour 5 and resettlement groove 3 bottoms.
The utility model will not have centre bore rotating shaft 5 clampings location through tailstock end fixture block 1, carry out Cylindrical Grinding Processes.In the course of processing, processed rotating shaft is in stable clamping positioning states all the time, and integral rigidity is good, helps obtaining good processing request.
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 range to be defined by appending claims and equivalent thereof.
