Description

A kind of fan blade cutter sweep

Technical field

The utility model relates to a kind of cutter sweep, a kind of fan blade cutter sweep.

Background technology

At present in fan industry, the making of draught fan impeller is often divided into three steps, the most respectively to blade and wheel Hub carries out blanking shaping, then by blade uniform welding on wheel hub, finally according to actually required size to leaf Sheet carries out cutting process.And be the most all on blade, to carry out marking by tradition scoring tool at present, Then directly held plasma cut head by staff and carry out hand cut, the most do not only exist operation fiber crops Shortcoming tired, that labour intensity is big, poor stability, cutting efficiency are low, and owing to there is man's activity, cutting Precision is relatively low, it is impossible to ensure cut quality.

Utility model content

For the problems referred to above, the problem that the utility model intends to solve is to provide a kind of simple and reasonable, use Convenient and safe, labour intensity is little, cutting efficiency is high and the fan blade cutter sweep of good cutting effect, significantly Improve cutting accuracy, cut quality is effectively ensured.

For reaching above-mentioned purpose, the utility model by the following technical solutions: a kind of fan blade cutter sweep, Including base, main shaft, rotational lantern ring, rule, movable block, spring shell, coil tension spring, contiguous block, Plasma cut head, controller and location-plate, described base is fixed with a main shaft, and described main shaft is with described The center line of base on the same line, described main shaft is arranged with a rotational lantern ring, on described rotational lantern ring Being fixed with a rule, described rule is perpendicular with described main shaft, described rule is arranged with one and moves Block, the top of described movable block is provided with fastening bolt, and the bottom of described movable block is fixed with a spring shell, Being provided with a coil tension spring in described spring shell, the bottom of described spring shell is provided with a through hole, described through hole Inside being arranged with a contiguous block, one end of described contiguous block is connected with described coil tension spring, described contiguous block another One end is fixed with a plasma cutting head, and described plasma cut head is connected with controller, and described plasma is cut Cut and on the side of head, be further fixed on a location-plate.

As preferably, being shaped as of described contiguous block is I-shaped.

As preferably, the material of described rule is Q235B.

Effective achievement of the present utility model: the utility model is simple and reasonable, during use, first by turning set Ring is taken down from main shaft, is set on main shaft by impeller to be cut simultaneously, the rotational lantern ring that then will just now take off It is enclosed within again on main shaft, then according to the actually required size of blade, moves to movable block on the scale refer to Location is put, and fixes by fastening bolt, now under the effect of coil tension spring, and the bottom of location-plate and blade Contacting, plasma cut head is just directed at cutting position, finally starts controller, allows plasma cut head Carry out cutting work.Wherein rule and the supporting setting of movable block, it is not necessary to allow artificial by tradition stroke again The Line tool carries out marking on blade, is substantially reduced the labour intensity of staff, improves cutting efficiency； By contiguous block, coil tension spring and spring shell plasma cut head is fixed on movable block carry out supporting Cutting work, is no longer by hand cut, is not only used conveniently and safely, and reduce staff further Labour intensity, improve cutting efficiency and cutting accuracy；And the setting of location-plate, further increase cutting Precision, it is ensured that cut quality.

In sum, the utility model have simple and reasonable, be used conveniently and safely, labour intensity is little, Cutting efficiency height and the feature of good cutting effect, be greatly improved cutting accuracy, cut quality be effectively ensured.

Accompanying drawing explanation

Fig. 1 is the structural representation under the utility model use state.

In figure: 1-base, 2-main shaft, 3-rotational lantern ring, 4-rule, 5-movable block, 6-spring shell, 7-stretches Contracting spring, 8-contiguous block, 9-plasma cut head, 10-controller, 11-location-plate, 12-fastening bolt.

Detailed description of the invention

In order to make those skilled in the art be better understood from the utility model scheme, below in conjunction with this enforcement Accompanying drawing in example, carries out clear, complete description to the technical scheme in the utility model embodiment.

As it is shown in figure 1, the utility model discloses a kind of fan blade cutter sweep, including base 1, main shaft 2, rotational lantern ring 3, rule 4, movable block 5, spring shell 6, coil tension spring 7, contiguous block 8, etc. from Sub-cutting head 9, controller 10 and location-plate 11, base 1 is fixed with a main shaft 2, main shaft 2 and base 1 Center line on the same line, main shaft 2 is arranged with a rotational lantern ring 3, rotational lantern ring 3 is fixed with a moment Degree chi 4, rule 4 is perpendicular with main shaft 2, and rule 4 is arranged with a movable block 5, the top of movable block 5 Being provided with fastening bolt 12, the bottom of movable block 5 is fixed with a spring shell 6, is provided with one and stretches in spring shell 6 Contracting spring 7, the bottom of spring shell 6 is provided with a through hole, is arranged with a contiguous block 8 in through hole, contiguous block 8 One end is connected with coil tension spring 7, and the other end of contiguous block 8 is fixed with a plasma cutting head 9, and plasma is cut Cut 9 to be connected with controller 10, the side of plasma cut head 9 is further fixed on a location-plate 11, contiguous block 8 be shaped as is I-shaped, and the material of rule 4 is Q235B.

Effective achievement of the present utility model: the utility model is simple and reasonable, during use, first by turning set Ring 3 is taken down from main shaft 2, is set on main shaft 2 by impeller to be cut, the rotation then will just now taken off simultaneously The collar 3 is enclosed within main shaft 2 again, then according to the actually required size of blade, by movable block 5 on rule 4 Move to specify position, and fix by fastening bolt 12, now under the effect of coil tension spring 7, location-plate The bottom of 11 contacts with blade, and plasma cut head 9 is just directed at cutting position, finally starts controller 10, allow plasma cut head 9 carry out cutting work.Wherein rule 4 and the supporting setting of movable block 5, no Need to allow the artificial tradition scoring tool that passes through carry out marking on blade again, be substantially reduced staff's Labour intensity, improves cutting efficiency；By contiguous block 8, coil tension spring 7 and spring shell 6, plasma is cut Cut 9 to be fixed on movable block 5 and carry out supporting cutting work, be no longer by hand cut, not only use Convenient and safe, and the further labour intensity reducing staff, improve cutting efficiency and cutting accuracy；And The setting of location-plate 11, further increases cutting accuracy, it is ensured that cut quality.

Obviously, described embodiment is only a part of embodiment of the present utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creativeness The every other embodiment obtained under work premise, all should belong to the scope of the utility model protection.
