Abstract
The utility model relates to a grinding head automatic feed device exclusively used on a knife sharpener. The utility model is composed of a ratchet mechanism, a link mechanism and a driving member; the utility model aims at purposes that the feeding amount of a grinding head can be automatically and accurately fed. The utility model is used on a knife sharpener, the grinding head can run stably, the feeding amount can be adjusted, and the grinding and cutting precision of knife blades can be raised.
Description
The utility model relates to a kind of bistrique auto-feeder that is exclusively used on the knife sharpener.
Grinding wheel feed amount on the domestic existing knife sharpener is to realize by handle drive worm screw and elevating screw.Though it is comparatively general that present this feed arrangement is used, because by manual operation, its fluctuation of service, the amount of feeding is inaccurate, and the precision of blade grinding is not high, so be difficult to adapt to some fine finishining occasions.
The purpose of this utility model is a kind of automatic feeder that is exclusively used on the knife sharpener of design, and it makes grinding wheel feed amount auto-feed and accurate.
In order to achieve the above object, the utility model adopts following technical solution: design a kind of automatic feeder, it is made of ratchet, ratchet, linkage, driving link, housing, wherein, ratchet is installed on the feed worm axle set on the knife sharpener, linkage is made of swing arm connecting rod, swing arm, ratchet one end and swing arm one end are hinged, the other end inserts the teeth groove of ratchet, the swing arm other end and swing arm rod hinge connection, the swing arm connecting rod other end and housing are hinged, driving link also with the swing arm rod hinge connection.When driving link drives the swing arm connecting rod jack-up that makes progress, and be transferred to swing arm, swing arm is moved upward, push the ratchet rotation by the ratchet in the swing arm then, realize the auto-feed of grinding wheel feed amount and accurately by feed worm through-drive to elevating screw again.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the present embodiment structure chart.
As shown in Figure 1, present embodiment is made of ratchet (1), ratchet (6), linkage, cylinder (3), housing (7) it, wherein, ratchet (1) is installed on the feed worm axle (2) that was provided with originally on the knife sharpener, linkage is made of swing arm connecting rod (4), swing arm (5), and be arranged in the housing (7), they are installed on the grinding head box body side together.Ratchet (6) one ends and swing arm (5) one ends are hinged, the other end inserts the teeth groove of ratchet, swing arm (5) other end and swing arm connecting rod (4) one ends are hinged, and swing arm connecting rod (4) other end is hinged on housing (7), and the piston rod (8) of cylinder (3) is hinged with swing arm connecting rod (4).Be provided with spacing set screw (9) on swing arm (5) top corresponding shell (7), it is large and small to regulate swing arm (5) stroke by set screw (9), realizes the adjusting of grinding wheel feed amount.Simultaneously, set up outside auxiliary equipment: gas generation apparatus---air pump, gas control equipment---magnetic valve, and electric control circuit.
When knife sharpener grinding blade finishes a stroke, the electric part action, magnetic valve work, make cylinder (3) action, cylinder (3) piston rod (8) is jack-up swing arm connecting rod (4) upwards, drives swing arm (5) and moves upward, ratchet (6) in the swing arm (5) pushes ratchet (1) rotation, drive feed worm axle (2) rotation, be transferred to elevating screw, realize the auto-feed of grinding wheel feed amount.After next stroke begins, the electric part dead electricity, the magnetic valve commutation, drive cylinder piston connecting rod (8) and swing arm connecting rod (4), swing arm (5), ratchet reset, for auto-feed is next time prepared.
Driving link in the utility model also structures such as available hydraulic, electromagnet, mechanical oblique impact piece as drive unit.
In sum, the utility model compared with prior art has the following advantages as the grinding wheel head feed apparatus on the knife sharpener:
1, the grinding wheel feed amount accurately and can regulate;
2, bistrique operates steadily;
3, can improve the blade grinding accuracy.
