Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, specifically to an abrasive grinding wheel combining resin and diamond. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are abrasive tools in which ordinary abrasive grains are bonded together with a binder into a specific shape (mostly circular with a central through-hole) and possess a certain strength. Diamond grinding wheels are used for machining hard and brittle non-metallic materials (such as glass, ceramics, gemstones, and semiconductor materials) and cemented carbide, or for machining high-hardness, high-brittleness, and difficult-to-machine materials (such as PCD diamond sheets, PCBN cubic boron nitride sheets, and wear-resistant cast iron) due to their high hardness, wear resistance, and compressive strength. Resin, as a self-sharpening agent with good elasticity and adaptability, is often used to bond with diamond to form abrasive tools suitable for machining cemented carbide, optical / electronic materials, and brittle non-metallic materials.

[0003] Grinding wheels typically have an abrasive layer (formed by abrasive and a binder) attached to a substrate. By rotating the substrate, the abrasive layer rotates to grind the workpiece. In existing technologies, the connection structure between the abrasive layer and the substrate is to directly bond or fix the abrasive layer to the side of the substrate. This results in a small bonding area and weak bonding force. During grinding, the bonding strength of the abrasive layer on the substrate is easily reduced due to stress, affecting the grinding quality. Utility Model Content

[0004] This invention provides an abrasive wheel combining resin and diamond to increase the bonding area and bonding strength between the abrasive layer and the substrate.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: an abrasive grinding wheel combining resin and diamond is provided, the innovation of which is: it includes a cylindrical aluminum substrate, and a connecting ring plate is provided on the outer side of the aluminum substrate, the connecting ring plate being sleeved on the outer side of the aluminum substrate;

[0006] The aluminum substrate has a connecting through hole at its center; and the central axis of the connecting ring plate coincides with the central axis of the connecting through hole.

[0007] The connecting ring plate is provided with an expansion connection structure. The surface of the connecting ring plate is coated with an abrasive layer. The abrasive layer is used to wrap the connecting ring plate and the expansion connection structure. After the abrasive layer hardens, it forms a cutting element. The expansion connection structure is used to lock the cutting element on the connecting ring plate.

[0008] Furthermore, a reinforcing portion extends upward from the top of the aluminum substrate, and the reinforcing portion is frustum-shaped; the reinforcing portion and the aluminum substrate are integrally formed, and the connecting through hole penetrates through the reinforcing portion and the aluminum substrate.

[0009] Furthermore, there is one connecting ring plate, which is connected to the middle of the side of the aluminum substrate.

[0010] Furthermore, the expansion connection structure consists of several reinforcing through holes evenly distributed along the circumference of the connecting ring plate, and the abrasive layer is provided to wrap around the connecting ring plate along the circumference on the side of the aluminum substrate, and is provided to penetrate the connecting ring plate through the reinforcing through holes.

[0011] Furthermore, there are two connecting ring plates, which are respectively connected to the upper and lower parts of the side of the aluminum substrate.

[0012] Furthermore, the expansion connection structure consists of several reinforcing through holes evenly distributed along the circumference of the two connecting ring plates. The abrasive layer is provided to wrap around the two connecting ring plates along the circumference on the side of the aluminum substrate and is provided to penetrate the two connecting ring plates through the reinforcing through holes.

[0013] Furthermore, the reinforcing through holes on the two connecting ring plates are staggered in the vertical direction.

[0014] Furthermore, the expansion connection structure includes several reinforcing through holes and several reinforcing grooves. The reinforcing holes are evenly distributed around the circumference on the upper connecting ring plate, and the reinforcing grooves are evenly distributed around the circumference on the lower connecting ring plate. The reinforcing grooves are respectively located below the reinforcing through holes. The abrasive layer is set to wrap around the two connecting ring plates around the side of the aluminum substrate, and passes through the upper connecting ring plate through the reinforcing through holes and is connected to the reinforcing grooves.

[0015] Furthermore, several baffles are evenly arranged along the circumference inside the reinforcing groove. The baffles extend from the inner sidewall of the reinforcing groove towards the center of the groove, and the length of the baffles accounts for 1 / 3 to 1 / 2 of the inner diameter of the reinforcing groove. The reinforcing groove extends upward to the top, which is higher than the upper surface of the corresponding connecting ring plate.

[0016] Furthermore, the abrasive layer is made of a mixture of resin and diamond.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] This embodiment provides an abrasive wheel combining resin and diamond, including a cylindrical aluminum substrate 1, with a bonding ring plate 2 on the outer side of the aluminum substrate 1, the bonding ring plate 2 being sleeved on the outer side of the aluminum substrate 1.

[0033] A connecting through hole 4 is provided at the center of the aluminum substrate 1; and the central axis of the connecting ring plate 2 coincides with the central axis of the connecting through hole 4.

[0034] The connecting ring plate 2 is provided with an expansion connection structure 3. The surface of the connecting ring plate is coated with an abrasive layer 5. The abrasive layer 5 is used to wrap the connecting ring plate 2 and the expansion connection structure 3. After the abrasive layer 5 is hardened, a cutting element is formed. The expansion connection structure 3 is used to lock the cutting element on the connecting ring plate 2.

[0035] In this embodiment, a connecting ring plate 2 is provided on the side of the aluminum substrate 1, and an expansion connection structure 3 is provided on the connecting ring plate 2. The abrasive layer 5 and the connecting ring plate 2 are connected by the expansion connection structure 3, which increases the connection area and the bonding strength between the abrasive layer and the aluminum substrate 1, further ensuring the grinding quality and efficiency of the grinding wheel as an abrasive tool.

[0036] Example 2

[0037] Based on the above embodiments, in this embodiment, a reinforcing portion 6 extends upward from the top of the aluminum substrate 1, and the reinforcing portion 6 is frustoconical in shape; the reinforcing portion 6 and the aluminum substrate 1 are integrally formed, and a connecting through hole 4 is provided that penetrates the reinforcing portion 6 and the aluminum substrate 1. Figure 4 As shown.

[0038] In this embodiment, a reinforcing part 6 extends from the aluminum substrate 1, which can further increase the rigidity of the aluminum substrate 1 and improve the grinding stability of the grinding wheel during the rotation grinding process.

[0039] Example 3

[0040] Based on the above embodiments, the number of connecting ring plates 2 in this embodiment is one, such as... Figure 1 As shown, the connecting ring plate 2 is connected to the middle of the side of the aluminum substrate 1. In use, the abrasive layer 5 wraps around the connecting ring plate 2, indirectly increasing the connection area with the aluminum substrate 1 and improving the bonding force with the aluminum substrate 1.

[0041] Example 4

[0042] Based on the above embodiments, the expansion connection structure 3 of this embodiment consists of several reinforcing through holes 31 evenly distributed along the circumference of the connecting ring plate 2, such as... Figure 1-3 As shown, the abrasive layer 5 is provided to wrap around the bonding ring plate 2 along the circumference on the side of the aluminum substrate 1, and is provided to penetrate the bonding ring plate 2 through the reinforcing through hole 31.

[0043] In this embodiment, the expansion connection structure 3 consists of several reinforcing through holes 31 evenly distributed along the circumference of the connecting ring plate 2. In use, the abrasive layer 5 is wrapped around the connecting ring plate 2 and is set through the reinforcing through holes 31. During the grinding process, the abrasive layer 5 will generate heat, and the resin will expand due to the heat and fill the reinforcing through holes 31, forming a compression on the connecting ring plate 2. This can enhance the connection stability between the abrasive layer 5, the connecting ring plate 2, and the aluminum substrate 1 during the grinding process.

[0044] Example 5

[0045] Based on the above embodiments, the number of connecting ring plates 2 in this embodiment is two, such as... Figure 5 As shown, two bonding ring plates 2 are respectively connected to the upper and lower parts of the side of the aluminum substrate 1. In use, the abrasive layer 5 is wrapped around the two bonding ring plates 2, further increasing the connection area with the aluminum substrate 1 and improving the bonding force with the aluminum substrate 1.

[0046] Example 6

[0047] Based on the above embodiments, the expansion connection structure 3 of this embodiment consists of several reinforcing through holes 31 evenly distributed along the circumference on the two connecting ring plates 2, such as... Figure 5 and 6 As shown, the abrasive layer 5 is provided to wrap around two connecting ring plates 2 along the circumference on the side of the aluminum substrate 1, and is provided to penetrate the two connecting ring plates 2 through the reinforcing through hole 31.

[0048] In this embodiment, both connecting ring plates 2 are provided with reinforcing through holes 31. When the resin and diamond abrasive are coated on the aluminum substrate 1 and wrapped around the two connecting ring plates 2, the resin and diamond abrasive can penetrate through the reinforcing through holes 31 on the two connecting ring plates 2. Compared with embodiment 4, the bonding force between the abrasive layer 5 and the connecting ring plate 2 is stronger and the connection is more stable.

[0049] Example 7

[0050] Based on the above embodiments, in order to enhance the bonding strength, the reinforcing through holes 31 on the two bonding ring plates 2 in this embodiment are staggered in the vertical direction.

[0051] Based on Example 6, this embodiment misaligns the reinforcing through holes 31 on the upper and lower connecting ring plates 2, allowing the abrasive material entering between the two connecting ring plates 2 through the reinforcing through holes 31 to connect between the two connecting ring plates 2, thereby further increasing the bonding area and improving the bonding force.

[0052] Example 8

[0053] Based on the above embodiments, the expansion connection structure 3 of this embodiment includes several reinforcing through holes 31 and several reinforcing grooves 32. The several reinforcing holes are evenly distributed along the circumference on the upper connecting ring plate 2, and the several reinforcing grooves 32 are evenly distributed along the circumference on the lower connecting ring plate 2. The reinforcing grooves 32 are respectively provided below the reinforcing through holes 31. The abrasive layer 5 is provided to wrap around the two connecting ring plates 2 along the circumference on the side of the aluminum substrate 1, and passes through the upper connecting ring plate 2 through the reinforcing through holes 31 and is connected in the reinforcing grooves 32.

[0054] The expansion connection structure 3 in this embodiment includes a reinforcing through hole 31 and a reinforcing groove 32. The abrasive that enters through the reinforcing through hole 31 or between the two connecting ring plates 2 enters the reinforcing groove 32, further increasing the bonding area between the abrasive and the expansion connection structure 3. The bonding area can be larger due to the thermal expansion of the resin, thereby further improving the bonding force and grinding stability.

[0055] Example 9

[0056] Based on the above embodiments, in this embodiment, a number of partitions 33 are evenly arranged along the circumference of the reinforcing groove 32. The partitions 33 extend from the inner sidewall of the reinforcing groove 32 toward the center of the reinforcing groove 32, and the length of the partitions 33 accounts for 1 / 3 to 1 / 2 of the inner diameter of the reinforcing groove 32.

[0057] In this embodiment, the partition 33 increases the contact area between the abrasive entering the reinforcing groove 32 and the reinforcing groove 32 (i.e., the abrasive entering the reinforcing groove 32 also connects with each partition 33). When the resin expands due to heat, the increased contact area improves the bonding force and grinding stability. The reinforcing groove 32 extends upwards to a top surface higher than the corresponding upper surface of the connecting ring plate 2. For example... Figure 7-9 As shown.

[0058] In this embodiment, the extension of the reinforcing groove 32 increases the bonding between the extended part and the abrasive, further improving the bonding force.

[0059] Example 10

[0060] Based on the above embodiments, the abrasive layer in this embodiment is made of a mixture of resin and diamond.
