Abstract
The invention discloses a tailstock-end clamping block applied to a process for grinding an excircle of a rotating shaft without a central hole and clamping the two ends of the rotating shaft without the central hole, and the tailstock-end clamping block is characterized by being symmetrically provided with four internal threaded through holes, wherein one end of the tailstock-end clamping block is provided with a setup groove, the other end of the tailstock-end clamping block is provided with a bearing chamber, and the internal threaded through holes are communicated with the setup groove. By using the tailstock-end clamping block disclosed by the invention, a rotating shaft without the central hole is clamped and positioned, and the excircle of the rotating shaft without the central hole is ground; and in the process of machining, the machined rotating shaft is always in a stable clamping and positioning state, good in overall rigidity, and favorable for obtaining machining requirements, so that an excircle ground as above complies with design requirements and is good in apparent mass.
Description
Technical field
The present invention 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, particularly be 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.
Summary of the invention
The technical problem that the present invention 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, technical scheme of the present invention 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 invention has the beneficial effects as follows:
The present invention will not have centre bore rotating shaft clamping location through tailstock end fixture block, carry out Cylindrical Grinding Processes.In process, 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 embodiment of the invention 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; Accompanying drawing in describing below only is some embodiments of the present invention; 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 tailstock end fixture block of the present invention;
Fig. 2 is tailstock end fixture block of the present invention and rotating shaft clamping sketch map;

The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to shown in Figure 1; The present invention 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; Said internal thread through hole 2 communicates with said resettlement groove 3, and said resettlement groove 3 is cylindrical.
To shown in Figure 3, method for using of the present invention 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 tailstock end fixture block 1 of the present invention.
It is 1-2mm with the distance of resettlement groove bottom surface that the present invention 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 present invention will not have centre bore rotating shaft 5 clampings location through tailstock end fixture block 1, carry out Cylindrical Grinding Processes.In process, 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 present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just illustrates principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention; The present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
