Abstract

The utility model discloses an emery cloth wheel structure for polishing machinery, by the emery cloth piece stack and become the mounting of emery cloth ring sum fixed emery cloth ring utensil centre bore and constitute, wherein: the abrasive cloth sheets form a dish-shaped abrasive cloth ring with a low center and a high periphery when being overlapped. Because the periphery of the disc-shaped abrasive cloth ring is high and the center is low, when the disc-shaped abrasive cloth ring is contacted with a workpiece, the abrasive cloth ring has a yielding space, namely the abrasive cloth ring has certain elasticity, so that the contact force of the abrasive cloth ring and the workpiece can be increased, and the working efficiency is improved; the metal protective layer can improve the fixing strength and avoid the damage of the fixing piece; the coaxiality of the abrasive cloth wheel is ensured, and the working precision is improved.

Description

The emery cloth wheel construction

Technical field

The utility model is the emery cloth wheel construction that is used for grinding machine about a kind of.

Background technology

As shown in Figure 1, 2, flat surface abrasive cloth wheel is to be formed by stacking a flat surface abrasive cloth ring 1 ' by multi-disc emery cloth sheet 11 ', by fixing formation of red steel paper 2 ' (or glass fibre) clamping of two tool centre bores 21 ' up and down, the emery cloth of this structure is taken turns following problems can occur in actual use:

1, emery cloth wheel integral hardness is not good: because the emery cloth wheel is to be formed by stacking a plane by emery cloth sheet 11 ', red steel paper 2 ' is also fixed for the clamping on plane simultaneously, then nonelastic with contacting of workpiece when the emery cloth wheel rotates at a high speed, the not good and apparent emery cloth wheel of contact strength integral hardness deficiency.

2, emery cloth is taken turns dangerous hidden danger: because of the emery cloth sheet 11 ' of stack by red steel paper 2 ' clamping, the clamping intensity of red steel paper 2 ' is limited, when rotating at a high speed, red steel paper 2 ' also breaks, emery cloth sheet 11 ' can scatter to fly out and injure the workman.

3, the polishing precision is not enough: because emery cloth wheel centre bore 21 ' is to be formed by red steel paper 2 ', the long-term use is easy to wear and tear, and centre bore can enlarge, and eccentric phenomena occurs and influence the polishing precision.

The utility model content

Main purpose of the present utility model provides a kind of emery cloth wheel construction that can increase overall structure hardness.

Secondary objective of the present utility model provides and a kind ofly can improve security to increase the emery cloth wheel construction in service life.

For achieving the above object, solution of the present utility model is: a kind of emery cloth wheel construction, by the emery cloth sheet be formed by stacking the emery cloth ring and fixedly the fixture of emery cloth ring tool centre bore constitute, wherein: this emery cloth sheet is at the low peripheral high dish-shaped emery cloth ring in when stack formation center.

Described fixture is red steel paper or glass fibre, at its outside coat of metal that increases.

Described fixture directly is a coat of metal.

Described coat of metal is formed with the dish-shaped radian of 3 degree to 15 degree in response to dish-shaped emery cloth annular shape.

The one-body molded same shrinkage pool that goes out to protect emery cloth wheel centre bore of described coat of metal.

After adopting such scheme,, thereby can have following improvements when using because the utility model emery cloth wheel construction is the whole emery cloth ring that forms the high dish of the low periphery in a center:

1, increased the structural rigidity of emery cloth wheel: because its peripheral high center of emery cloth ring of dish is low, when contacting with workpiece, the emery cloth ring has between the appearance of yielding, and promptly the emery cloth ring has certain elasticity, thereby can increase the dynamics that contacts of emery cloth ring and workpiece, increase work efficiency.

2, increase service life: add the layer of metal protective layer owing to fixture or at fixture, can improve strength of fixation, avoid the fixture breakage.

3, improve operating accuracy: because the one-body molded inward recess that goes out to protect emery cloth wheel centre bore of this coat of metal, metal has anti abrasive characteristic, can guarantee that the axiality of emery cloth wheel improves operating accuracy.

The specific embodiment

To shown in Figure 5, emery cloth wheel construction of the present utility model reaches the fixedly red steel paper of emery cloth ring 1 (or glass fibre) 2 formations by emery cloth ring 1 as Fig. 3.

This emery cloth ring 1 is to form the high dish-shaped emery cloth ring of the low periphery in center during by multi-disc emery cloth sheet 11 stack; Then up and down two tool centre bore 21 red steel papers 2 at the fixing also low peripheral high disc structure in formation center during emery cloth ring 1 of clamping; Outside at last red steel paper 2 adds layer of metal protective layer 3 again; this coat of metal is formed with the dish-shaped radians of 3 degree to 15 degree in response to the shape of emery cloth ring 1 and red steel paper 2, also one-body moldedly simultaneously goes out inward recess 31 with on the inwall that is linked in red steel paper 2 centre bores 21.Certainly fixedly emery cloth ring 1 can directly adopt metal level.

Just because of the utility model emery cloth ring 1 is set to the high disc structure of the low periphery in center, the red steel paper 2 outer coat of metals 3 that add one deck tool dish radian that clamping simultaneously is fixing, the whole emery cloth wheel that then constitutes is when higher peripheral contact workpiece, lower center has certain yielding space, be that emery cloth ring 1 has certain elasticity, can increase the dynamics that contacts of emery cloth ring 1 and workpiece, increase work efficiency; And coat of metal 3 can improve the constant intensity of red steel paper, avoids 1 breakage of emery cloth ring to scatter; Moreover the inward recess 31 of the one-body molded protection emery cloth wheel centre bore 21 that goes out of this coat of metal 3, have anti abrasive characteristic, can avoid the centre bore wearing and tearing to enlarge, guarantee that the axiality of emery cloth wheel improves operating accuracy.
