Description
Technical field
The utility model relates to grinding apparatus technical field, particularly a kind of instrument for manual grinding magnetic core.
(1) background technology
The transformer used in some tests needs constantly to regulate some parameters, make by hand so mostly still adopt, this is comprising manual grinding magnetic core, because its size of magnetic core is less, the file that a lot of people uses some small-sized is now polished, but the polishing time is longer, and efficiency is low, and requires great effort especially.
(2) utility model content
The utility model, in order to make up the deficiencies in the prior art, provides the instrument for manual grinding magnetic core that a kind of structure is simple, laborsaving, save the polishing time.
The utility model is achieved by the following technical solution:
A kind of instrument for manual grinding magnetic core, comprise support, roller bearing and emery wheel, it is characterized in that: described pedestal upper end is provided with bearing, roller bearing is rack-mount by bearing, described roller bearing front end is provided with emery wheel, the roller bearing of emery wheel both sides is provided with retainer ring and is fixed on roller bearing by retainer ring, and roller bearing rear end is connected with crank.
Described roller bearing front end is provided with external screw thread, and described retainer ring is the nut mutually mated with external screw thread, is convenient to the replacing of emery wheel and fixes.
The beneficial effects of the utility model are: the utility model structure is simple, convenient, flexible adjustment, can select the emery wheel of different-thickness according to the size of magnetic core, polishing magnetic core is out relatively more even, owing to selecting best contact surface, the polishing time can also be saved, due to the invariant position of emery wheel, only need hand to control magnetic core well, more laborsaving, convenient and practical, be suitable for wide popularization and application.
(3) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
In figure, 1 emery wheel, 2 roller bearings, 3 supports, 4 bearings, 5 external screw threads, 6 retainer rings, 7 cranks.
(4) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises support 3, roller bearing 2 and emery wheel 1, it is characterized in that: described support 3 upper end is provided with bearing 4, roller bearing 2 is arranged on support 3 by bearing 4, described roller bearing 2 front end is provided with external screw thread 5, emery wheel 1 is installed on external screw thread 5 place of roller bearing 2, and emery wheel 1 both sides are provided with retainer ring 6 and are fixed on roller bearing 2 by retainer ring 6, and described retainer ring 6 is the nut mutually mated with external screw thread 5, be convenient to the replacing of emery wheel 1 and fix, roller bearing 2 rear end is connected with crank 7.
Rotating crank 7 during use makes roller bearing 2 drive emery wheel 1 to rotate, and makes magnetic core contact with emery wheel 1 simultaneously, according to the magnetic core that difference requires, and the dynamics that the speed of adjustable rotation crank 7 or magnetic core contact with emery wheel 1, convenient, flexible adjustment.Use this instrument, although emery wheel 1 is in rotation, the position of emery wheel 1 does not change, and only needs the position changing magnetic core, greatly can save strength.
The utility model structure is simple, convenient, flexible adjustment, can select the emery wheel of different-thickness according to the size of magnetic core, polishing magnetic core is out relatively more even, owing to selecting best contact surface, the polishing time can also be saved, due to the invariant position of emery wheel, only need hand to control magnetic core well, more laborsaving, convenient and practical, be suitable for wide popularization and application.
Claims (2)
1. the instrument for manual grinding magnetic core, comprise support, roller bearing and emery wheel, it is characterized in that: described pedestal upper end is provided with bearing, roller bearing is rack-mount by bearing, described roller bearing front end is provided with emery wheel, the roller bearing of emery wheel both sides is provided with retainer ring and is fixed on roller bearing by retainer ring, and roller bearing rear end is connected with crank.
2. the instrument for manual grinding magnetic core according to claim 1, is characterized in that: above-mentioned roller bearing front end is provided with external screw thread, and described retainer ring is the nut mutually mated with external screw thread, is convenient to the replacing of emery wheel and fixes.
