Abstract
The utility model relates to an electric poloidal abrader. A fan adopts a centrifugal and axial-flow combined structure; vanes adopt forward tilting curved designs; a vane direct current air outlet is additionally provided with curved retainer ring; the central part of one end of the vane direct current air outlet is provided with a middle end plate to improve both the centrifugal effect and the axial-flow effect of the fan. A brake press-button of the utility model adopts a center symmetric structure, the manufacture is simple, and the disassembly of abrasive wheels is convenient.
Description
The utility model relates to a kind of sanding machine, particularly a kind of hand held, electric electric angle grinder.
In the prior art, electric hand angular grinder is a lot, be mainly used in metal removing surface, the unhairing of parts in addition, weld seam bevel and sand milling; thin-wall pipes and light shape cutting etc., but the fan structure of existing sanding machine is single, is generally centrifugal or axial-flow type; blade is a linear pattern, and its air-out effect is undesirable; And existing sanding machine also exists dismounting emery wheel inconvenience, and structure is problem such as compactness inadequately.
The purpose of this utility model provides a kind of compact conformation, and the dismounting emery wheel is convenient, the electric hand angular grinder that air-out effect is good.
The utility model is realized by following technical proposal:
Fan of the present utility model adopts the composite construction of centrifugal and axial-flow type, its blade adopts the design of FC shaped form, add the curved surface back-up ring at blade direct current air outlet position, and establish a middle end plate in direct current air-out one end centre, make the air that enters fan enter and can not return from the other end at this end.
Locking key of the present utility model adopts the center symmetrical structure.
The utility model compared with prior art because fan adopts composite construction centrifugal and axial-flow type, blade adopts the design of shaped form FC, the centrifugal effect of air-out is better than linear pattern blade; Add the curved surface ring washer at blade direct current air outlet position, make the axial flow air-out effect more obvious; Establish a middle end plate in blade direct current air-out one end centre, make the air that enters fan enter and can not return from the other end at this end.Locking key of the present utility model adopts the center symmetrical structure, makes manufacturing process simple, the emery wheel convenient disassembly.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model fan structure left view.
Accompanying drawing 3 is the utility model fan structure right view.
Accompanying drawing 4 is the utility model fan A-A cutaway view.
Accompanying drawing 5 is the utility model D-D cutaway view.
Below in conjunction with accompanying drawing the utility model being done one describes in detail.
As shown in Figure 1, the utility model is mainly by protecgulum (1), gear wheel (2), output shaft (3), needle bearing (4), reduction box (5), pinion (6), fore bearing (7), bearing gland (8), casing (13), rear bearing (14), back handle (15) and switch (16) are formed, critical piece in the casing (13) is stator (11), rotor (12), fan (9), establish a grade solar or lunar halo (10) behind the fan (9), fan structure such as Fig. 2,3, shown in 4, article 37, shaped form blade (21) is FC and evenly distributes, at blade (21) direct current air outlet position curved surface ring washer (22) is arranged, end plate (24) in the middle of blade direct current air-out one end (23) centre establishes one, make the air that enters fan enter and can not return in this end (23) from the other end (25), fan (9) is gone up also has 8 uniform reinforcements (26).
Locking key structure of the present utility model as shown in Figure 5, its tripping spring (17), ring washer (18), brake bar (19) and locking key (20) formula that is centrosymmetric.
Claims (2)
1, a kind of electric hand angular grinder, comprise output shaft, reduction box, fan, stator, rotor, casing, locking key, switch, it is characterized in that: fan (9) is the composite structure of centrifugal and axial-flow type, blade (21) adopts the FC curved configuration, at the position of blade (21) direct current air outlet one curved surface ring washer (22) is arranged, end plate (24) in the middle of blade direct current air-out one end centre establishes.
2, according to the described electric hand angular grinder of claim 1, it is characterized in that: locking key (20) the formula structure that is centrosymmetric.
