Poking device
Technical field
This utility model belongs to emery wheel and produces apparatus field, is specifically related to a kind of poking device.
Background technology
There are the circular bonded abrasive tool of through hole in the central authorities that emery wheel abrasive material and bonding agent resin etc. are made.Emery wheel is the one that in grinding tool, consumption is maximum, use face is the widest, high speed activities during use, can roughly grind metal or the cylindrical of non-metal workpiece, inner circle, plane and various profiles etc., partly refine and refine and fluting and cut-out etc..Before compacting, filling raw material in dies cavity, if only moved flat on surface, after having suppressed, the internal feed distribution of emery wheel is uneven, affects the quality of emery wheel.
Summary of the invention
This utility model provides a kind of poking device, overcomes the problem pockety of raw material in prior art.
This utility model is by the following technical solutions: poking device, and including switch-plate, described switch-plate is rack-mount, support casing is located on fixing sleeve, is provided with screw rod in fixing sleeve, and fixing bush outer sleeve is provided with quill, quill bottom is provided with female thread, and female thread coordinates with screw rod.
Described switch-plate is connected with connecting plate, and connecting plate is fixed on support.
Being provided with fixing scale on described fixing sleeve, quill is provided with movable mark.
The beneficial effects of the utility model are: rotary moveable sleeve interlocks switch-plate and moves up and down, and by the moving flat in layer of the raw material in dies cavity, improve the uniformity of emery wheel density;This utility model simple in construction, mounting and adjusting is convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, poking device, including the switch-plate 4 for stirring emery wheel raw material, switch-plate 4 is connected with connecting plate 6, connecting plate 6 is fixed on support 9, support 9 is set on fixing sleeve 7, is provided with screw rod 8 in fixing sleeve 7, is arranged with quill 5 outside fixing sleeve 7, quill 5 bottom is provided with female thread 3, female thread 3 coordinates with screw rod 8, and fixing sleeve 7 is provided with fixing scale, and quill 5 is provided with movable mark.
Being provided with mould 1 on workbench 2, screw rod 8 is mounted on bearings, and bearing is arranged in the centre bore of mould 1 inner chamber, and movable adjusting nut adjusts the position of switch-plate, and workbench 2 driven mold 1 is movable, and switch-plate 4 stirs raw material in mould 1 inner chamber.Switch-plate 4 is connected with support 9 by connecting plate 6, extends switch-plate, and then increases the adjusting range of distance bottom switch-plate and dies cavity.
