The specific embodiment
The invention discloses a kind of flap disc, to improve the grinding efficiency of flap disc.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
See also Fig. 1-Fig. 5, the structural representation of the flap disc that Fig. 1 provides for the embodiment of the invention; The upward view of the flap disc that Fig. 2 provides for the embodiment of the invention; The structural representation of the mount pad that Fig. 3 provides for the embodiment of the invention; The structural representation of the flap disc main body that Fig. 4 provides for the embodiment of the invention; The structural representation of the pressing plate that Fig. 5 provides for the embodiment of the invention.
A kind of flap disc comprises flap disc body 2, and flap disc body 2 comprises the flap disc matrix, and the flap disc matrix is provided with the second boss 7; Flap disc also comprises:
The mount pad 1 of metal material offers the first installing hole 3 that cooperates with the sanding machine main shaft on the mount pad 1, the end face that mount pad 1 and flap disc matrix are fitted is provided with excircle and the flap disc matrix inner periphery dimensional fits of the first boss 4, the first boss 4;
The flap disc that this programme provides, mount pad 1 is by the first boss 4 and integral body of flap disc matrix inner periphery mix proportion, mount pad is metal installation base, Metal Phase has higher intensity for glass fibre, can bear larger centrifugal force, namely can bear larger rotating speed, the rotating speed of flap disc has improved, and grinding efficiency has also just improved accordingly.The erection sequence that the flap disc of this programme is installed from top to bottom is mount pad 1-flap disc body 2-pressing plate 5 successively, the device that the three is formed is installed on the sanding machine main shaft, offer the screwed hole that cooperates with the sanding machine main shaft in the second installing hole 6, screw thread to offer direction consistent with the rotation direction of sanding machine main shaft, can be more and more compacter in rotation process center platen 5 and the combination of flap disc body 2, mount pad 1 also can be compacter with being connected of flap disc body 2, increased stability and security that device uses.The flap disc that this programme provides, mount pad are metal material, and the intensity of self is just higher, consider from saving material and environmental protection equal angles, but the intensity relative reduce of flap disc matrix adopt comparatively environmental protection and lower-cost material to make.Because the main glass fibre that adopts is made the flap disc matrix in the prior art, the glass fibre cost is high, glass fibre is difficult for decomposing after poisonous and discarded, environmental pollution is serious, the flap disc that this programme provides mainly is that mount pad 1 bears centrifugal force with the integral body that flap disc body 2 forms, metal has higher intensity, so that flap disc can bear larger rotating speed, the centrifugal force that flap disc body 2 bears reduces greatly, so the flap disc matrix can adopt the lower material of intensity, the matrix that this programme adopts is plastics, the matrix of nylon or sponge, plastics, nylon and string are more common material, cost compare is low, and degradable and can reusing after discarded, has reduced the pollution to environment.The device that provides of this programme has higher stability and higher safety coefficient in sum, adopt simultaneously the matrix of plastics, nylon or sponge to replace the glass fibre matrix of poisonous and not environmental protection, reduced on the one hand the cost of producing and using, on the other hand low-carbon environment-friendly.
After using a period of time, flap disc body 2 needs to change, pressing plate 5 need to be taken off from the sanding machine main shaft, in order to make things convenient for the installation and removal of pressing plate, be provided with for the hole 8 for the spanner clamping at pressing plate 5, during dismounting, the bare terminal end of spanner reached in the hole 8, opposite spin pressing plate 5 to flap disc rotates can take off pressing plate 5.
Mount pad 1 is the mount pad of aluminum alloy materials, also can be irony or copper mount pad.The preferred aluminum alloy materials that adopts, aluminium alloy density is low, and intensity is high, and plasticity is good, and corrosion resistance is good, long service life.
In order further to optimize technique scheme, in a specific embodiment of the present invention, be provided with cavity between the first boss 4 and the first installing hole 3, on the basis that guarantees mount pad 1 intensity, saved material, reduced cost.
In order further to optimize technique scheme, in a specific embodiment of the present invention, flap disc matrix inner periphery diameter is large than the diameter of the first installing hole 3, greatly reduced centrifugal force, safety coefficient is higher in the use, and stability is better, production and applying unit cost are lower, on the basis of proof strength, reduced the material that matrix uses, saved cost.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
