The specific embodiment
Referring to figs. 1 through Figure 10, shown in the figure embodiment of use preferred for this invention, a kind of structure improved grinder that present embodiment provides comprises:
One base 1, the platform 11 of this base 1 is provided with a workbench 12, this workbench 12 is to be used for fixing workpiece 2 (workpiece in the present embodiment is that the sawtooth with saw blade is processed as example), and the emery wheel 13 of this workpiece 2 of grinding, this workbench 12 is to be slidedly arranged on the platform 11 with a transmission mechanism 3 drives and level, this emery wheel 13 is that this slide 131 is perpendicular to the glide direction cunning of this workbench 12 and establishes on the slide 131 of being located on the platform.
One turning cylinder 4, it uprightly is pivoted in base 1 and is stretched on the platform 11, and connects a connecting rod 41 at the end that stretches out platform 11, and this connecting rod 41 is connected with slide 131, and drives emery wheel 13 toward polyslip.
At least one belt pulley 42, it is fixed on the turning cylinder 4, and has two annular groove (not shown)s.Only be provided with a belt pulley 42, two annular grooves in the present embodiment and be located on this belt pulley 42 and adjacent setting, the groove footpath of two annular grooves is identical.
One first motor 5 and one second motor, 6, the first motors 5 are to drive emery wheel 13 feeds when grinding work-piece 2, and second motor 6 is that this two motor is sheathed on the annular groove of belt pulley 42 respectively with belt 51,61 in the 2 back rapid returns of emery wheel 13 grinding work-pieces.
In the present embodiment, the axle 52 of first motor 5 is provided with the belt wheel at a slow speed 53 of a sheathed belt 51, the axle 62 of second motor 6 is provided with the quick belt wheel 63 of a sheathed belt 61, the girth of the belt 61 that this quick belt wheel 63 is sheathed is greater than this girth of the sheathed belt 51 of belt wheel 53 at a slow speed, therefore when first motor 5 and second motor 6 are constant-speed motor, the stroke distances that the stroke distances that the quick belt wheel 63 of second motor 6 rotates a circle rotates a circle greater than the belt wheel at a slow speed 53 of first motor 5, relatively under this second motor 6 drive rotating ratio first motor 5 height of belt pulleys.
Two touch parts 43 are sheathed on the turning cylinder 4 respectively and the location, and this two touch part 43 is cam-like in the present embodiment, and is fixed on the turning cylinder 4 by a screw 431 respectively.
One starting switch 7 and a shutdown switch 8, this starting switch 7 is for 6 entrys into service of control second motor, and shutdown switch 8 is to shut down for control second motor 6, two switches be located at base 1 and respectively with turning cylinder 4 on touch part 43 corresponding settings, starting switch 7 and shutdown switch 8 have a touching portion 71 respectively, 81, touch part 43 for correspondence triggers when turning cylinder 4 rotates, two touch parts 43 are touching portions 71 of respectively corresponding starting switch 7 and shutdown switch 8,81 stir highly is provided with, starting switch 7 is limit switch with shutdown switch 8 in the present embodiment, and touching portion 71,81 is driving lever.
From the above, as Fig. 6 and shown in Figure 9, after two touch parts 43 unclamp screw 431, can adjust the relative position of itself and turning cylinder 4 respectively, and two touch parts 43 are in the process that turning cylinder 4 rotates a circle, wherein a touch part triggers induction starting switch 7 earlier, make 6 entrys into service of second motor, and when turning round to another touch part 43 triggering induction shutdown switches 8, second motor 6 stops, therefore the stroke distances of 43 of two touch parts is relevant with the startup time point and the duration of runs of second motor 6, and the adjustment of the stroke distances by 43 of two touch parts can be controlled the startup time point and the duration of runs of second motor 6.
As shown in Figure 3, transmission mechanism 3 comprises a swinging axle 31, this swinging axle 31 is uprightly to be located in the base 1, and in base 1, has one first swing arm 32, for driving this swinging axle 31 pivots pendulum, on turning cylinder 4, has a cam 44, these cam 44 interlocks first swing arm 32 swings, and the end of first swing arm 32 is provided with a bearing 33, this bearing 33 be abut against in cam 44 and with its rotation yaw, this swinging axle 31 is pivot pendulum when rotating with swinging axle 31 stretching out sheathed one second swing arm of an end 34, the second swing arms 34 on the platform 11, second swing arm 34 is provided with a top brace part 341 at its end, and top brace part 341 is to drive workbench 12 to produce displacement in the little progress mode.
In addition, the end of top brace part 341 has apical tooth 3411, be provided with a toothrow 122 at workbench 12, apical tooth 3411 engagements for top brace part 341 are shored, draw hammer 35 in workbench 12 hangings one, this draws hammer 35 to provide the pulling force of workbench 12 single directions, just workbench 12 is utilized the gravity that draws hammer 35 and pulls to an end, workbench 12 is provided with a location division 36 in addition, when top brace part 341 breaks away from toothrow 122, workbench 12 is temporarily shored in location division 36, to prevent that workbench 12 from towards drawing hammer 35 directions to pull out, therefore providing the power of oppositely shoring of drawing hammer 35 when toothrow 122 little progress.
By the said structure explanation as can be known, turning cylinder 4 is when emery wheel 13 feed cutting workpieces 2 (as shown in Figure 4), be turning cylinder 4 to be rotated by first motor 5, as Fig. 5, shown in Figure 6, when one of them of two touch parts 43 triggers starting switch 7,6 startups of second motor, and the rotating speed that drives turning cylinder 4 because of second motor 6 is higher than first motor 5, therefore 4 rotating speeds by second motor 6 of turning cylinder drive emery wheel 13 withdrawings (as shown in Figure 7), another touch part 43 triggers shutdown switch 8 (as Fig. 8 on turning cylinder 4, shown in Figure 9), drive emery wheel 13 feed cutting workpieces 2 by first motor 5 this moment again, so can make the withdrawing speed of emery wheel 13 faster than feed velocity.
The present invention utilizes two first motor 5 and second motors 6 with high low speed difference to drive turning cylinder 4 in base, make the speed of emery wheel 13 withdrawings faster than feed, thereby shorten process time, under the identical time, conventional grinder can be processed 100 saw blades, then the present invention can process 150, this shows that the present invention has the effect that improves production capacity.
Certainly, the present invention is not limited to the foregoing description, and the present invention also can have other structural change, as long as it reaches technique effect of the present invention with essentially identical means, all should belong to protection scope of the present invention.
