Abstract

The utility model relates to a high precision knife sharpener with the functions of sharpening, machining and processing knife blades of a printing industry and a wood industry. The utility model is characterized in that a knife sharpening assembly and a corresponding lift-adjusting device are additionally arranged on the knife sharpener, aiming at purposes that the knife sharpener not only can carry out rough machining to the knife blades, but also can carry out precision processing to knife edges; the utility model brings convenience to the rough machining and the fine machining of the knife blades, the sharpness, the durability and the roughness of machined knife blades can be improved, and a high precision knife sharpener with a single head or unidirectional multi-split heads can be fabricated.

Description

High-accuracy knife sharpener

The utility model relates to the knife sharpener technical field, and is particularly a kind of to the high-accuracy knife sharpener that prints and wood industry industry blade carries out the grinding processing.

Domestic existing knife grinding equipment has two kinds: a kind of is peripheral milling, and a kind of is the end face mill, but because they all can only blade advance roughing, can not carry out precision processing to the edge of a knife.Therefore, existing knife sharpener can not fundamentally improve edge of a knife roughness and thoroughly eliminate burr, makes blade not reach very high cutting precision.

The purpose of this utility model is that design a kind ofly can blade be carried out roughing, can carry out the high-accuracy knife sharpener of precision processing again to the edge of a knife.

In order to achieve the above object, the utility model adopts following technical solution: a kind of high-accuracy knife sharpener, it contains main box, saddle, bistrique assembly and corresponding elevation and subsidence regulating device, on the opposite side main box of bistrique assembly, establish sharpening assembly and corresponding elevation and subsidence regulating device, link by center bolt and pressing handle between main box and the saddle.When bistrique is finished blade roughing, by rotating pressing handle and center bolt, unclamp main box, the sharpening assembly is commutated, is adjusted to Working position, then the edge of a knife is carried out precision processing, thereby make knife sharpener realize and blade to carry out roughing, can carry out the purpose of precision processing again the edge of a knife.

In order to achieve the above object, the utility model also can adopt following another technical solution: a kind of high-accuracy knife sharpener, contain bistrique assembly, main box, saddle, set up a main box in addition on saddle, main box is provided with sharpening assembly and corresponding elevation and subsidence regulating device.When the bistrique blade was carried out roughing, the sharpening assembly was regulated away from the edge of a knife by corresponding elevation and subsidence regulating device.After roughing finishes, make bistrique away from the edge of a knife, regulate the sharpening assembly then, the edge of a knife is carried out precision processing to Working position by regulating bistrique assembly elevation and subsidence regulating device.Thereby make knife sharpener also can realize and blade to carry out roughing, can carry out the purpose of precision processing again the edge of a knife.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a blade abrasive machining device structure chart in the present embodiment 1.

Fig. 2 is present embodiment 2 structural representations.

With reference to shown in Figure 1, the abrasive machining device of blade is mainly by end face bistrique assembly (7) in the present embodiment 1, bistrique assembly elevation and subsidence regulating device (6), main box (2), sharpening assembly (1) and corresponding elevation and subsidence regulating device (2) constitute, main box (12) is by center bolt (15), pressing handle (5) and the holddown spring (4) that is contained on the center bolt are connected with support plate (9), support plate (9) is fixed on the saddle (9), sharpening assembly (1) is located at the opposite side of end face bistrique assembly (7), they are arranged on the main box (12) together, and all be provided with corresponding elevation and subsidence regulating device (2) respectively, (6), it is by worm screw (19), worm gear (18) constitutes; Sharpening assembly (1) is made up of polished silicon wafer (13), (14) of driving motor (17) and a pair of move toward one another, housing (20) other end and the sharpening assembly casing (3) at polished silicon wafer (13) place are movably hinged, and on housing (20), be provided with adjusting bolt (16), the universal connection of block (21) on regulating bolt (16) and being fixed on casing (3).Can regulate angle between polished silicon wafer (13), (14) by adjusting nut (16).

During the processing blade, blade is fixed on the knife rest (10), blade adjustment is arrived suitable angle by magnechuck, simultaneously, by regulating bistrique assembly elevation and subsidence regulating device (6), bistrique is adjusted to Working position, start bistrique (8) and feed stroke blade is carried out roughing.After the completion of processing, unclamp and compress palm (5), holddown spring (4) is with main box (12) jack-up upwards, produce the gap between main box (12) and the support plate (9), main box (12) can be rotated easily by center bolt (12), thereby the sharpening assembly is changed to Working position, the angle of regulating polished silicon wafer then reaches, upper/lower positions, the edge of a knife is carried out precision processing, wherein, polished silicon wafer (13), (14) on, upper/lower positions is regulated by sharpening assembly elevation and subsidence regulating device (2), polished silicon wafer (13), (14) angle between is regulated by regulating bolt (16).During precision processing, polished silicon wafer (13) is handled edge of a knife front, and polished silicon wafer (14) is handled the edge of a knife back side, with removal edge of a knife burr, thereby improves blade sharpness, durability, roughness, and the cutting precision of blade.

Embodiment two:

As shown in Figure 2, present embodiment 2 is set up a main box (22) in addition at saddle on existing knife sharpener basis, and main box (22) is provided with sharpening assembly and corresponding elevation and subsidence regulating device, as the precision processing device of the edge of a knife.Difference from Example 1 is that sharpening assembly and bistrique assembly branch are arranged, and sharpening assembly and corresponding elevation and subsidence regulating device are identical with embodiment 1, and concrete structure can be with reference to embodiment 1.When the bistrique blade was advanced roughing, polished silicon wafer was regulated away from the edge of a knife by elevation and subsidence regulating device.After roughing finished, bistrique was regulated sharpening assembly and polished silicon wafer to Working position then by regulating away from the edge of a knife, simultaneously, regulated the angle between the polished silicon wafer, realized the edge of a knife is carried out precision processing.

In sum, the utility model compared with prior art has the following advantages:

1, blade roughing and edge of a knife precision processing conversion is convenient, brings for the blade Roughing and fine machining Greatly convenient.

2, the edge of a knife just, the burr at the back side can both totally be removed, and makes blade sharpness, anti-Be greatly enhanced with property and roughness.

3, because the polished silicon wafer angle can be regulated, can both carry out precision processing to various blades.

4, can be made into single head or equidirectional many high-accuracy knife sharpeners separately.
