Abstract
The utility model discloses a central hole grinding machine for a shaft, comprising a bench drill main shaft, wherein an upper grinding tip is fixed on the bench drill main shaft; a lower tip fixing seat is fixed just below the bench drill main shaft, and is provided with a bearing seat; the bearing seat is provided with a lower grinding tip by a bearing; the axis line of the lower grinding tip is coincided to that of the upper grinding tip; the tip part of the lower grinding tip extends out of the upper end of the bearing seat; the lower end of the lower grinding tip extends out of the lower end of the bearing seat; the lower extending end of the lower grinding tip is fixedly provided with a tip belt disc which is connected with a driving belt disc fixed on a motor output by a same belt. In the central hole grinding machine, the whole process spends 6 seconds, and the fussiest and most time-wasting turning and clamping time is saved, so that the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of grinder, especially relates to a kind of class centre-hole lapping machine.
Background technology
Grinding is utilize to apply or press to be embedded in the abrasive grain on the lap tool, the finished machined of finished surface being carried out through lap tool and the relative motion of workpiece under certain pressure.As everyone knows; The centre bore of axial workpiece is extremely important; Because processing might as well, detect, and will be benchmark with the centre bore all, the quality of centre bore quality is directly connected to the quality quality that the processing axle is gone up each spot size precision and shaped position precision; So before carrying out important processing, all want elder generation that the two ends centre bore of axle is carried out smooth grinding processing.Its operating procedure when existing centre-hole lapping machine grinds centre bore, program are following: the carbide-tipped center that 1. central aperture scroll chuck under the polished axial workpiece is clamped is loaded onto and is set upright; 2. go up carbide-tipped center and rotate at a high speed, aim at firmly downwards that centre bore grinds on the axostylus axostyle; 3. unclamp toply, take off part tune switching-over, aim at top loading onto down.Going up top high speed rotation firmly grinds last centre bore; 4. unclamp toply, take off part and accomplish the two ends centre bore and grind; Process next workpiece and repeat above step, program.Whole process is such: aim at top down load onto set upright → go up top high speed rotation aim at downwards go up centre bore → reinforcing gradually → high speed spin finishing → unclamp top → taking off commutates → loads onto set upright → go up top high speed rotation aim at downwards upward centre bore → reinforcing gradually → high speed spin finishing → unclamp top → take off the centre bore grinding of part completion two ends.In whole 12 seconds of process time spent, therefore existing grinder grinding shaft centre bore labour intensity is big, consuming time.
The utility model content
The utility model technical problem to be solved is to provide a kind of simple in structure, the axle type centre-hole lapping machine that working (machining) efficiency is high.
The technical scheme of the utility model is following: a kind of class centre-hole lapping machine; Comprise the bench drill main shaft; On this bench drill main shaft, be fixed with in the grinding toply, its main points are: under said bench drill main shaft, be fixed with top holder down, on the top holder of this time, bearing block be installed; Be equipped with under the grinding top through bearing on this bearing block; Under the said grinding in top axial line and the said grinding top axial line overlap, top top part is stretched out said bearing block upper end under the said grinding, said bearing block lower end is stretched out in this grindings time top lower end; Top external part down is fixed with top belt pulley under said grinding, and this top belt pulley is gone up fixing active belt pulley through same belt with motor output and linked to each other.Adopt above structure, operating procedure, program that axle class centre bore is ground are following: top loading onto set upright under 1. central aperture under the polished axial workpiece being ground; 2. go up carbide alloy and grind to go up top high speed rotation, firmly aim at downwards on the axial workpiece on the centre bore top, the at this moment upper and lower top while rotates at a high speed, but direction of rotation is opposite, simultaneously upper and lower centre bore is ground; 3. it is upward top to unclamp grinding, takes off part, promptly accomplishes the two ends centre bore and grinds.Process next workpiece and repeat above step, program.Whole process is such: aim to grind top down load onto set upright → grindings go up top high speed rotation aim at downwards the high speed spin finishing of upward axial workpiece centre bore → reinforcing gradually → up and down → unclamp top → take off axial workpiece.Whole 6 seconds of process time spent, saved tune loaded down with trivial details, the most consuming time, clamping time, improved production efficiency.
As preferably: be provided with chute on the top holder down said, both sides, said bearing block lower end are positioned at said chute, and this bearing block can move forward and backward along top holder down.
Beneficial effect: saved tune loaded down with trivial details, the most consuming time, clamping time 6 seconds during the whole process of the utility model, improved production efficiency; The utlity model has characteristics such as cost is low, simple in structure, good reliability.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See also Fig. 1: a kind of class centre-hole lapping machine; Comprise bench drill main shaft 1; On this bench drill main shaft 1, be fixed with in the grinding toply 2, under said bench drill main shaft 1, be fixed with top holder 3 down, bearing block 4 is installed on the top holder 3 of this time; On this bearing block 4 through bearing be equipped with grind under top 5; Under the said grinding in top 5 axial line and the said grinding top 2 axial line overlap, top 5 top part is stretched out said bearing block 4 upper ends under the said grinding, this grinding is stretched out said bearing block 4 lower ends in top 5 lower ends down; Top 5 times external parts are fixed with top belt pulley 6 under said grinding, and this top belt pulley 6 is gone up fixing active belt pulley 9 through same belt 7 with motor 8 outputs and linked to each other.
In Fig. 1, it can also be seen that: be provided with chute 3a on the top holder 3 down said, both sides, said bearing block 4 lower end are positioned at said chute 3a, and this bearing block 4 can move forward and backward along following top holder 3.
The above is merely the preferred embodiment of the utility model; It is not restriction with the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
