Abstract
The utility model discloses a drill sharpening machine, which mainly comprises an upper cover, a motor, a gear coupling rod, an annular grinding wheel cup, a drill bit locator, etc. The utility model is characterized in that a low-tension DC permanent-magnet motor is fixed on the upper cover, the shaft of the motor is fixed to the gear coupling rod, a locating sleeve of the grinding wheel is sheathed above the gear coupling rod, the annular grinding wheel cup is fixed to the locating sleeve of the grinding wheel, and a drill bit locator is arranged above the locating sleeve of the grinding wheel. The utility model has the advantages of reasonable structure and smart design. The accuracy of the processing can be ensured because the effect of grinding the drill bit can be achieved by inserting the drill bit into the corresponding hole of the drill bit locator instead of holding the drill manually. The drill sharpening machine is safe, reliable and convenient because the hands and the eyes of the operator can be protected by the internal grinding.
Description
Technical field:
The utility model relates to a kind of sharpening machine, particularly relates to a kind of sharpening machine that 115 degree spiral bits are polished.
Background technology:
At present, known 115 degree spiral bits to passivation are polished and are mostly manual operations, and promptly hand-held drill bit is polished on emery wheel, because drill bit is smaller, the operator has to be positioned as close to the emery wheel of rotation at a high speed, is easy to like this cause the accident; And, owing to be manual operations, can not guarantee the angle of drill bit, thereby influence the service efficiency of drill bit.
Summary of the invention:
Technical problem to be solved in the utility model provides and a kind ofly can effectively overcome above-mentioned defective, need not the manual brill of holding, only sharpening machine that can the automatically grinding drill bit in inside.The technical scheme that its technical problem that solves the utility model adopts is, a kind of sharpening machine, mainly form by loam cake, motor, driving coupling bar, toroidal wheel cup, drill bit locator etc., its characteristics are: on cover fixed for the low-voltage direct magneto, motor shaft tightens set driving coupling bar, its top is with the emery wheel positioning sleeve, and the toroidal wheel cup is fixed on the emery wheel positioning sleeve, and the top of emery wheel positioning sleeve is provided with the drill bit locator.Owing to adopt such scheme; be not difficult to draw and the utlity model has following beneficial effect, the utility model is rational in infrastructure, is skillfully constructed; need not the manual brill of holding; only need drill bit is inserted in the respective aperture of drill bit locator, can reach the effect of polishing drill bit, guaranteed the precision after the processing; and polishing is carried out in tool interior; protected operator's trick, safe and reliable, convenient and swift, have promotional value.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Figure is the structural representation in the utility model vertical section.
The specific embodiment:
Among the figure, be fixed with low-voltage direct magneto 3 on the sharpening machine loam cake 10,3 in motor tightens set driving coupling bar 4, its top is with emery wheel positioning sleeve 5, inside is provided with spring 9, toroidal wheel cup 6 is fixed on the emery wheel positioning sleeve 5, and the top of emery wheel positioning sleeve 5 is provided with drill bit locator 7, is fixed with adjusting knob 8 on the drill bit locator 7.
During enforcement, the urban network electricity source is transported to power supply converter 2 by power line 11 and switch 1, power supply converter 2 is pressed urban network electricity and is changed into the 12V low-voltage dc power supply to low-voltage direct magneto 3, it is turned round with 2600rpm/min, power is delivered to cover emery wheel positioning sleeve 5 thereon by the driving coupling bar 4 that is fastened on the motor shaft, thereby drive the toroidal wheel cup 6 that is fixed on the emery wheel positioning sleeve 5, make its speed rotation with 2000rpm/min.In the inside of emery wheel positioning sleeve 5 spring 9 is arranged, regulate the relative position of toroidal wheel cup 6 and drill bit locator 7, thereby control the degree of polishing drill bit by the adjusting knob 8 that is fixed on the drill bit locator 7.
In practical operation, only drill bit need be inserted in the respective aperture on the drill bit locator 7, drill bit is owing to the gravity of self will contact with the toroidal wheel cup 6 of rotation, two alignment pins are all arranged in each aperture on drill bit locator 7, guarantee that drill bit does not rotate, thus the buffed surface of control drill bit.The grinding angle of drill bit is to become 115 degree to realize by the buffed surface on the toroidal wheel cup 6, after the one side of drill bit is ground, only needs drill bit is mentioned, and the Rotate 180 degree inserts and gets final product.
Claims (2)
1, a kind of sharpening machine, mainly form by loam cake, motor, driving coupling bar, toroidal wheel cup, drill bit locator etc., it is characterized in that: on cover fixed for the low-voltage direct magneto, motor shaft tightens set driving coupling bar, its top is with the emery wheel positioning sleeve, the toroidal wheel cup is fixed on the emery wheel positioning sleeve, and the top of emery wheel positioning sleeve is provided with the drill bit locator.
