Description

Cup-shaped polishing wheel with functional plate TECHNICAL FIELD

[0001] The present application relates to the field of polishing, in particular to a cup-shaped polishing wheel with a functional plate. BACKGROUND

[0002] The organic binder cup-shaped polishing wheel is composed of organic binder, abrasive, polishing agent, filler, pore-forming agent and other components, which is different from the polishing wheel of sandpaper type, cloth wheel type, fiber type and surface inlay type in the consolidation mode on the surface of the base material. The organic binder cup-shaped polishing wheel belongs to the inlay type, and each component is fully mixed and solidified to form a product. The working mechanism of the polishing wheel is different from that of the surface inlay type. The organic binder mainly includes polyurethane and rubber materials. The finished product of the polishing wheel itself can present a certain non-structural elasticity.

[0003] The existing organic binder cup-shaped polishing wheel generally has high pore content, large elasticity and poor rotation strength. The polishing wheel is difficult to work under high linear speed conditions, which greatly limits the efficient polishing. Therefore, multiple abrasive particle size polishing wheels are usually used for multi-stage polishing processing to meet the quality requirements of workpiece polishing. The current improvement method mainly improves the bonding strength of the binder under low speed, and increases the pressure for use, but it is easy to cause burn and workpiece corner rounding during use, and the overall improvement degree is limited. In addition, the grinding heat is large during high linear speed and efficient polishing. If the pore content of the polishing wheel is increased, it will be difficult to handle due to the contradiction with the increase of the strength, and the elastic deformation of the grinding wheel will be large at high linear speed, which will deform the grinding surface of the polishing wheel and make it unstable.

[0004] ZL2021104697081, a polishing wheel with a protection structure, uses a high-strength continuous ring to sleeve the outer periphery of the abrasive ring (i.e. the polishing ring) composed of segment blocks. The wear rate of the abrasive ring is less than that of the outer ring, so that the outer ring does not affect the work of the abrasive ring, and can tightly clamp the outer periphery of the abrasive ring in the circumferential direction to the maximum extent, which can assist in improving the rotation strength of the abrasive ring, and the linear speed range of the abrasive ring is improved to adapt to higher linear speed conditions, so that the stability of the polishing wheel grinding form is improved to a certain extent, and high-quality polishing at higher linear speed is realized.

[0005] In order to further improve the polishing efficiency, the polishing quality and the stability of the grinding form, it is necessary to further improve the strength of the binder and reduce the elasticity of the binder, which will put higher requirements on the cooling conditions of the polishing wheel, especially in high-precision grinding processing, it is necessary to further improve the linear speed of the polishing wheel, and it is easy to realize. ZL2021104697081, a polishing wheel with a protection structure, is a grinding material ring composed of segments. Under the condition of further improving the linear speed, the radial internal stress of the segment is increased, the axial deformation is intensified, the risk of segment burst is gradually increased, and the stability of the grinding form is greatly reduced. The extrusion force between the axial segments increases, the difficulty of the water channel between the segments increases and the value decreases, which is difficult to meet the cooling needs of the polishing wheel, resulting in the burning of the polishing wheel and the workpiece during work, and the polishing surface quality is unqualified. Obviously, in order to further improve the performance of the polishing wheel, in addition to the improvement of the strength and rigidity of the segment, the solution of the cooling problem becomes the key. SUMMARY

[0009] On the basis of the above technical solution, the present application can also be improved as follows.

[0010] Further, the functional plate mechanism and the segment are installed on the end face or the peripheral surface of the base body.

[0011] The beneficial effects of the above further scheme are: beneficial to improve the applicability of the polishing wheel.

[0012] Further, when the functional plate mechanism and the segment are arranged on the end surface of the base body, the water passage is a groove penetrating the functional plate body in the radial direction; when the functional plate mechanism and the segment are arranged on the circumferential surface of the base body, the water passage is a groove penetrating the functional plate body in the axial direction.

[0013] The beneficial effect of the above further scheme is that the radially or circumferentially arranged water passage is conducive to ensuring the balanced cooling of the ring width of the grinding surface on different types of polishing wheels, thereby being suitable for high-speed, high-precision and high-surface-quality grinding and polishing processing.

[0015] The beneficial effect of the above further scheme is that the outer ring is sleeved on the functional plate mechanism and the segment, which is conducive to improving the rotation strength of the polishing wheel.

[0016] Further, the wear rate of the outer ring and the wear rate of the functional plate body are both greater than the wear rate of the segment.

[0017] The beneficial effect of the above further scheme is that it is conducive to avoiding the interference of the outer ring and the functional plate mechanism with the work of the segment.

[0018] Further, when the functional plate mechanism and the segment are arranged on the circumferential surface of the base body, at least one water supply groove is further included, the water supply groove is a radially arranged groove, and the two ends of the water supply groove are in communication with the outer diameter of the functional plate body and the inner cavity of the base body, respectively, and the water supply groove is in communication with a plurality of the water passages to form a mesh structure.

[0019] The beneficial effect of the above further scheme is that the water supply groove cooperates with the water passage to form a mesh structure, which is conducive to better water supply and chip removal effects.

[0020] Further, the number of the functional plate bodies is one or two, when the number of the functional plate bodies is one, the water passages are arranged on the two end sidewalls of the functional plate body, and a plurality of the water passages on the two end sidewalls are arranged alternately in the axial direction; when the number of the functional plate bodies is two, the water passages are arranged on one end sidewall of the functional plate body, and a plurality of the water passages on the sidewalls of the two functional plate bodies are arranged alternately in the axial direction.

Meanwhile, under the condition of turbid cooling water, the powder in the water channel at the working end surface can be separated from the water channel under the action of centrifugal force and friction force without affecting the cooling function of the water channel.

[0022] Further, when the number of the functional plate bodies is two, one end of the functional plate body on which the water channel is arranged is a concave-convex end, and the other end of the functional plate body away from the water channel is a plane end, and the concave-convex ends of the two functional plate bodies abut against each other or the plane ends abut against each other.

[0023] The beneficial effect of the above further scheme is that when the concave-convex ends of the two functional plate bodies abut against each other, it is conducive to reducing the pressure injury to the surface of the segment block, avoiding affecting the strength of the polishing wheel, and being suitable for the application scenario of the segment block with large elasticity and relatively low strength at a relatively low online speed; and when the plane ends of the two functional plate bodies abut against each other, the multiple concave-convex surfaces formed by the multiple water channels on the functional plate body can block the displacement of the segment block under the action of centrifugal force and release the internal stress of the segment block, which is suitable for the application scenario of the segment block with good rigidity and relatively high strength at a relatively high online speed.

[0024] Further, when the concave-convex ends of the two functional plate bodies abut against each other, the water channel is arranged obliquely, and the included angle between the water channel and the horizontal direction is between -25 degrees and 25 degrees.

[0063] The beneficial effects of the above preferred scheme are that the outer ring is sleeved on the functional plate mechanism and the segment, which is beneficial to improve the rotation strength of the polishing wheel.

[0064] Preferably, the wear rate of the outer ring 3 and the wear rate of the functional plate body 11 are both greater than the wear rate of the segment 2.

[0065] It should be noted that, as shown in FIGS. 1 and 2, in the initial state, the ring width and the ring height of the outer ring 3, the ring width and the ring height of the functional plate mechanism 1, and the ring width and the ring height of the segment 2 are basically equal, but as the continuous grinding processing, only when the wear rate of the outer ring 3 and the wear rate of the functional plate body 11 are both greater than the wear rate of the segment 2, it can be ensured that only the segment 2 is in contact with the workpiece to perform grinding processing.

[0066] The above-mentioned preferred scheme has the beneficial effect of being conducive to avoiding the interference of the outer ring and the functional plate mechanism with the segment.
