Abstract
The utility model relates to the improvement of an ordinary feed mechanism for sharpeners. The feed mechanism for sharpeners of the utility model comprises a feed driving device composed of a feed shaft, a gear, a rotational hand wheel, etc. The utility model is characterized in that the feed mechanism for sharpeners also comprises an automatic feed driving device composed of a gas pump, an overrunning clutch, a worm speed reducer, a feed shaft, an elastic wheel, etc. Compared with an ordinary mechanism, the feed mechanism for sharpeners has the advantages of high precision and high work efficiency.
Description
The present invention is the improvement to common knife sharpener feed mechanism.
Common knife sharpener, at its abrasion of grinding wheel after certain amount, need shake the rotation handwheel, and by rotating the gear on the handwheel and the transmission of the gear on the feed shaft, make the amount of spin that rotates handwheel be converted into the amount of feeding of feed shaft, thereby control the feeding that is contained in the emery wheel on the feed shaft.Above-mentioned knife sharpener feed mechanism, its shortcoming are the amount of feeding that can only operate the control emery wheel by hand, thereby influence the accuracy of the amount of feeding, also bring the not high shortcoming of knife sharpener operating efficiency simultaneously.
It is accurate to the purpose of this invention is to provide a kind of amount of feeding, the knife sharpener of high efficiency.
Describe content of the present invention in detail below in conjunction with the accompanying drawing among the present invention.
In the accompanying drawing, (1) is freewheel clutch, and (2) are to rotate handwheel, and (3) are the nuts that connects emery wheel, (4) be feed worm, (5) are feed shafts, and (6) are gears, and (7) are worm reducers, (8) be loosening and tightening wheel, (9) are the air pump push rods, and (10) are air pumps.
This feed mechanesm for sharpener, it contains the feed drive gearing that is made up of feed shaft (5), gear (6) and rotation handwheel (2) etc., also contain by air pump (10), freewheel clutch (1), the self-feeding transmission device that worm reducer (7) and feed shaft (5) and loosening and tightening wheel (8) etc. form.
When the knife sharpener self-feeding transmission device began to move, air pump (10) was at first worked, and air pump push rod (9) namely moves upward, and by connecting the bolt of air pump push rod and freewheel clutch (1), promoted freewheel clutch and rotate; Freewheel clutch of the present invention is mounted on the worm screw of worm reducer (7), and therefore, when freewheel clutch rotated, the worm and worm wheel of worm reducer also rotated thereupon; In addition, worm gear of the present invention does not adopt direct-connected mode with the feed shaft (5) that is positioned at the worm gear shaft core position, but feed shaft is connected with loosening and tightening wheel (8) by screw thread at the feeding the tip of the axis, when loosening and tightening wheel being tightened on worm gear or during with miscellaneous part that worm gear is connected, the worm gear of above-mentioned rotation can drive loosening and tightening wheel by frictional force and reach the feed shaft rotation that is connected with it, so feed shaft has namely been finished a feed motion, after loosening and tightening wheel is unscrewed, pneumatic self-feeding transmission device just can not have been controlled the feeding of feed shaft, certainly, if necessary, also available hand shaken is rotated handwheel (2), thereby promotes the feeding of feed shaft by gear (6).
Knife sharpener feed mechanism of the present invention by the stroke of control air pump push rod, can automatically be controlled the amount of feeding of feed shaft, that is the amount of feeding of emery wheel.Accuracy when therefore, the accuracy of its control amount of feeding is compared with manual operations is much higher.In addition, because the knife sharpener feed mechanism can be realized control automatically, its operating efficiency is also than much higher times of the operating efficiency of hand feeding mechanism.
Claims (1)
1, a kind of knife sharpener feed mechanism, it is characterized in that, comprise air pump 10 in the mechanism, freewheel clutch 1, worm reducer 7, loosening and tightening wheel 8, feed shaft 5, in the said air pump 10, its air pump push rod 9 is connected by bolt and surmounts main closing on the device 1, when feed mechanism begins to move, air pump 10 is at first worked, air pump push rod 9 promptly moves upward, and by connecting the bolt of air pump push rod 9 and freewheel clutch 1, promote freewheel clutch 1 and rotate, said freewheel clutch 1 is installed on the worm screw of worm reducer 7, therefore, when freewheel clutch 1 rotates, the worm and worm wheel of worm reducer 7 also rotate thereupon, and 8 one-tenths frictions of this worm gear and said loosening and tightening wheel are connected, that is snail can be delivered to frictional force loosening and tightening wheel 8 and drive loosening and tightening wheel 8 rotations when tiring out rotation, said loosening and tightening wheel 8 fuses by screw thread and feed shaft 5 at the end of said feed shaft 5, therefore, feed shaft 5 rotates along with the rotation of loosening and tightening wheel 8, finishes feed motion.
