Abstract

The utility model relates to an edge polisher which comprises a grab handle part, a grinding main body which is assembled on the grab handle part and protrudes from one end of the grab handle part, a grinding part assembled at one free end of the grinding main body, and a baffle which is assembled on the grinding main body and extends from one side of the grab handle part. The baffle and the grab handle part are respectively provided with a space for hands to hold, and the grinding part comprises two grinding wheels which are engaged with each other by the peripheries. The circumference of the end surface of each grinding wheel is provided with a cutting part in a sharp cone shape. An operator can hold the grab handle part by hands, and press the engaged parts of the cutting parts of the two grinding wheels against the rough edge of a piece to be ground. Then the edge polisher is dragged backwards by a force to grind the rough edge by the cutting parts, so that the operation is very convenient. Because one side of the grab handle part is provided with the baffle, when the utility model is operated, the baffle is positioned between the piece to be ground and the grab handle part. Though the edge polisher shifts a little when the force is applied, the hands can be prevented from being cut or wounded by the rough edge of the piece to be ground.

Description

Edger

Technical field

The utility model belongs to a kind of grinding tool, refers to a kind of edger in order to the metalwork burr that grind punch forming especially.

Background technology

Do not need excessively accurate metal sheet goods for tolerance, can punching out mode rapid shaping, but after the moulding, edge in finished product can produce burr, very easily hurt the people, so usually after punch forming, can grind with sand paper or file, yet, when grinding to hold file, outside finger and palm all are exposed to, the process of grinding, accidentally the utmost point can be drawn by burr and be injured, when grinding, need sand paper be pressed in burr with finger and grind with sand paper again,, when if burr scratch sand paper, also can hurt finger.No matter, the worry of security is arranged all so be when grinding with file or sand paper.

Summary of the invention

In order to improve above-mentioned shortcoming, main purpose of the present utility model is to provide a kind of edger of the security when guaranteeing grinding metal burr.

Based on above-mentioned purpose, technical conceive of the present utility model is to establish hard protective sheet between operator's hand and object one, in case hand directly touches the burr of object and be injured.

A kind of edger comprises: a shank part is the colloid body; One grinding main body, a wherein end of grinding main body places and is fixed in the shank part, and the other end is bent to form a kink, recessed V-shaped groove in the middle of the free end of kink forms; One grind section, comprise two with periphery mutually and abrasive wheel, two abrasive wheels be fixed in and the shank part angle less than these sides of kink of 180 degree, and lay respectively at the V-shaped groove both sides, the end face circumference of abrasive wheel forms blade; One baffle plate, on the same side that a wherein end of baffle plate and grind section are located at the grinding main body, the other end of baffle plate then is positioned at shank part one side and is provided with at interval with shank part.

Implement after the above-mentioned technological means, the utility model is gripped on shank part with hand when operation, the burr that blade intersection grinding by two abrasive wheels is to be ground, and the baffle plate of edger is just between hand and to be ground, so when being offset to some extent when application of force operation, the skew situation of its maximum is that baffle plate touches to be ground surface, so can guarantee that holding hand is not hurt by abrasive article, the security during with the raising edging.

The specific embodiment

See also Fig. 1, shown in 2, edger provided by the utility model comprise a shank part 10, be assembled on the shank part 10 and protrude in shank part 10 wherein the grinding main body 20, of an end be assembled in the baffle plate 40 that grinding main body 20 free-ended grind section 30 and are assembled on the grinding main body 20 and extend shank part 10 1 sides, wherein, described shank part 10 is a colloid body, it can grip for operation, shank part 10 inside are provided with the tank that is communicated with an end face wherein, place for grinding main body 20 and are fixed on the shank part 10.

Described grinding main body 20 is the metal lamellar body of a flat, this is held and is free end away from shank part 10 for it, the plate face of grinding main body 20 contiguous free ends bends an angle and forms kink 200, its free end and be made as towards the centre recessed V-shaped groove 21, be positioned on kink 200 plate bodys of V-shaped groove 21 both sides and be respectively equipped with a combined hole 22, use the grind section 30 of assembling on less than 180 these sides of degree at kink 200 shank parts 10 angles.

Grind section 30 comprises two abrasive wheels 31, abrasive wheel 31 centers are provided with combined hole 310, be placed through the combined hole 22 of kink 200 and the combined hole 310 of abrasive wheel 31 for coupling unit 35, abrasive wheel 31 is fixed on the kink 200 of grinding main body 20, in the middle of this preferred embodiment, the elongated slot that two combined holes 22 of described grinding main body 20 extend along V-shaped groove 21, use the fixed position of adjusting two abrasive wheels 31, and can adjust suitable fixed position according to the wheelspan of the abrasive wheel 31 of different size.

Again, the circumference that is positioned at abrasive wheel 31 end faces forms blade 311, please consult shown in Fig. 3 profile simultaneously, blade 311 is tilted to extend inwardly by abrasive wheel 31 peripheries and forms cone-shaped, burr with to be ground the A of blade 311 intersections grinding as illustrated in fig. 4 that utilize two abrasive wheels 31, when if the blade at this position 311 weares and teares because of frequent grinding, can release the combination assembly 35, abrasive wheel 31 rotations one angle is retightened again, can also abrasive wheel 31 upsets are fixing, with blade 311 grindings of other end.

Please consult Fig. 1 again, shown in 2, described baffle plate 40 is a metal plate, itself and grind section 30 are located on the same side of grinding main body 20, baffle plate 40 is fixed on the plate body of grinding main body 20 contiguous shank parts 10 these sections with an end wherein, the other end then is positioned at shank part 10 1 sides and is provided with at interval with shank part 10, when being gripped on shank part 10 for operator's hand, finger is placed through between shank part 10 and the baffle plate 40, again in baffle plate 40 away from shank part 10 these sides, recessed V shaped slab face in the middle of being made as when it is resisted against to be ground when surperficial, can form coating, the effect of guiding.

As shown in Figure 5, the operator held and holds shank 10 when the utility model used, and was resisted against to be ground A with the blade 311 of abrasive wheel 31 and had on the ora terminalis of burr, at this moment, between 40 proper hands of baffle plate and to be ground the A, dilatory edger promptly can pass through blade 311 grinding burr.

And since baffle plate 40 between hand and to be ground A; so can form the effect of protection hand; if in the process of grinding; angle is offset and when making to be ground A of hand deflection to some extent; promptly can utilize the V shaped slab bread of baffle plate 40 to be overlying on to be ground A surface; prevent that hand from being hurt by burr, guarantees work safety.
