Abstract
The utility model discloses a main shaft end clamp splice used in a two end clamping process for excircle grinding of a rotating shaft without a center hole. The main shaft end clamp splice is characterized in that four internal threaded through holes are symmetrically arranged on the main shaft end clamp splice; a placement groove is arranged at one end of the main shaft end clamp splice and a lug is arranged at the other end of the main shaft end clamp splice; and the internal threaded through holes are communicated with the placement groove. The main shaft end clamp splice has the following beneficial effects that: the rotating shaft without the center hole is clamped and positioned by the main shaft end clamp splice to undergo excircle grinding machining; in the machining process, the machined rotating shaft is always in the stable clamping and positioning state, has good integral stiffness and is beneficial to gaining good machining requirements; and the excircle machined by grinding conforms to the design requirement and has good apparent 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 spindle end fixture block of centre bore rotating shaft cylindricalo grinding two ends clamping technology.
Background technology
Existing spindle end fixture block generally all is used for not having the fixing no centre bore rotating shaft of centre bore rotating shaft cylindricalo grinding two ends clamping technology to be used, and 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 spindle 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 spindle 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 spindle end fixture block; Said spindle end fixture block one end is provided with a resettlement groove, and the other end is a projection, 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 the spindle 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 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 spindle end fixture block;
Fig. 2 is the utility model spindle end fixture block and rotating shaft clamping sketch map;
Fig. 3 is the utility model spindle end fixture block clamping sketch map.
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.
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 spindle end fixture block 1 of centre bore rotating shaft cylindricalo grinding two ends clamping technology; Said spindle end fixture block 1 one ends are provided with a resettlement groove 3; The other end is a projection 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:
An end that does not at first have centre bore rotating shaft 5 is placed in the resettlement groove 3 of said spindle end fixture block 1; Lock-screw 6 is fixed through 2 pairs of no centre bore rotating shafts 5 of internal thread through hole; The other end of no centre bore rotating shaft 5 is placed in the resettlement groove of grinding machine tailstock end fixture block 7; It is fixing through lock-screw 6, and holds out against and fix through grinding machine tailstock end pinnacle awl 8.Also be provided with bearing 9 in the said grinding machine tailstock end fixture block 7.The end that said spindle end fixture block 1 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 spindle end fixture block 1.
It is 1-2mm that the utility model does not have an end face and the distance of resettlement groove 3 bottom surfaces that centre bore rotating shaft 5 is placed in the resettlement groove 3.
The utility model will not have centre bore rotating shaft 5 clampings location through spindle 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 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.
