Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of hard and brittle material processing tools, specifically relating to a quick-loading diamond split grinding disc without welding grinding blocks. Background Technology
[0002] In modern manufacturing, especially in the processing of hard and brittle materials such as glass, ceramics, stone, silicon carbide, and refractory bricks, diamond grinding discs are widely used as a high-efficiency and wear-resistant grinding tool. Their core structure usually consists of a base plate and a working layer. The working layer is the part where diamond grinding blocks are installed, which is the key part for material removal and surface finishing. There are two main ways to fix the working layer of traditional diamond grinding discs: one is to weld multiple diamond grinding blocks directly to the base plate by high-frequency welding, and the other is to lock each grinding block to the base plate one by one by the built-in bolts.
[0003] Welding is a common installation method. Its basic principle involves using high-frequency induction heating to melt metal solder and weld the diamond grinding block to the base plate. This method offers advantages such as high connection strength, stable overall structure, and suitability for grinding operations under high-speed rotation. However, this process also presents significant problems. First, the welding process requires additional energy consumption, increasing manufacturing costs. Furthermore, the high temperatures generated during welding can cause thermal deformation of the base plate material, affecting the overall flatness and dynamic balance of the grinding disc, leading to a decrease in grinding quality. Second, the quality of the weld is affected by various factors, such as welding temperature control, solder composition, and operator skill level. If the weld is not strong, the grinding block may detach during high-speed rotation, posing a serious safety hazard. Additionally, replacing the grinding block after welding is extremely inconvenient. If a grinding block is severely worn or damaged, it must be cut and re-welded, resulting in long maintenance cycles, high costs, and severely impacting production efficiency and equipment utilization. The built-in bolt locking method is an alternative developed in recent years to overcome welding defects. The basic idea of this method is to pre-embed one or more bolts in each diamond grinding block and then fix it to the base plate with nuts. This method avoids the thermal stress problem caused by welding, improves the stability and safety of the product, and also makes the replacement of grinding blocks more convenient. However, this method also has obvious limitations. First, since each grinding block needs to be installed and tightened with bolts individually, the assembly process is cumbersome and time-consuming. Especially when the grinding disc diameter is large and the number of grinding blocks is large, the assembly efficiency is significantly reduced, which is not conducive to large-scale production. Utility Model Content
[0004] The purpose of this invention is to provide a quick-loading, weld-free diamond grinding disc for split-type grinding blocks, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] The weld-free, quick-loading, modular diamond grinding disc includes:
[0007] A base plate is movably connected to a split-type machine clamping ring on one side. Several diamond grinding blocks are inserted into the split-type machine clamping ring through openings. The base plate and the split-type machine clamping ring are connected by bolts through threaded holes. The number of bolts is eight. The diamond grinding blocks have a T-shaped cross-section. The base plate is connected to the output end of an external equipment motor via a coupling. The diamond grinding blocks are disposed between the base plate and the split-type machine clamping ring, and abut against one side of the base plate and the split-type machine clamping ring.
[0008] Preferably, the diamond grinding block is integrally formed by hot pressing and sintering, and the top view shape of the diamond grinding block includes round and square.
[0009] Preferably, the base plate has at least eight threaded holes, and the clamping ring of the split machine has a number of threaded holes corresponding to the base plate.
[0010] Preferably, the base plate and the clamping ring of the split machine are subjected to uniform pressure by bolts, so that the diamond grinding block is fixed between the base plate and the clamping ring of the split machine.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] (1) This utility model abandons the traditional high-frequency welding process and uses mechanical clamping to fix the diamond grinding block between the base plate and the split machine clamping ring. This design fundamentally avoids a series of problems that may occur during the welding process, such as thermal deformation, cracks, oxidation, and weld failure. It simplifies the production process of the grinding disc and improves production efficiency. At the same time, the fixed connection between the base plate and the split machine clamping ring can be achieved with a small number of bolts. The clamping action of the base plate and the split machine clamping ring tightly fixes the diamond grinding block in the middle, reducing assembly steps and time, and bringing convenience to users.
[0013] (2) By setting multiple corresponding threaded holes between the base plate and the clamping ring of the split machine, and using double-sided bolt locking, the clamping force is evenly distributed on the entire grinding disc structure, which effectively prevents the grinding block from shifting or loosening due to local stress concentration. At the same time, the diamond grinding block is designed with a T-shaped cross section, which can better match the opening of the clamping ring of the split machine, forming a self-positioning effect, further enhancing the stability and vibration resistance of the grinding block.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0020] Example 1:
[0021] Please see Figure 1 - Figure 4 As shown, the weld-free, quick-loading diamond grinding disc includes:
[0022] The base plate 1 has a split machine clamping ring 3 movably connected to one side. Several diamond grinding blocks 2 are inserted into the split machine clamping ring 3 through openings. Eight bolts 4 are connected between the base plate 1 and the split machine clamping ring 3 through threaded holes. The diamond grinding blocks 2 have a T-shaped cross-section. The base plate 1 is connected to the output end of the external equipment motor through a coupling. The diamond grinding blocks 2 are located between the base plate 1 and the split machine clamping ring 3, and abut against one side of the base plate 1 and the split machine clamping ring 3.
[0023] Specifically, the diamond grinding block 2 is integrally formed by hot pressing and sintering. The top view shape of the diamond grinding block 2 includes, but is not limited to, circles and squares. The base plate 1 has no less than eight threaded holes. The split machine clamping ring 3 has a number of threaded holes corresponding to the base plate 1. The base plate 1 and the split machine clamping ring 3 are subjected to uniform pressure by bolts 4, so that the diamond grinding block 2 is fixed between the base plate 1 and the split machine clamping ring 3.
[0024] As can be seen from the above, the base plate 1 is used to fix the split machine clamping ring 3, which is connected to the main shaft of the equipment motor to realize power input. During the assembly process, it works together with the split machine clamping ring 3 to clamp the diamond grinding block 2, ensuring its stable installation. The split machine clamping ring 3 has multiple openings for inserting the diamond grinding block 2, providing positioning support for the grinding block and preventing it from shifting or falling off. It cooperates with the base plate 1 to form a clamping space, stably clamping the diamond grinding block 2. The diamond grinding block 2 is the core component for realizing the grinding operation. Its cross-section is T-shaped. The grinding block is manufactured by hot pressing sintering integral molding process. The surface contains high-density diamond particles, which have excellent grinding performance. The T-shaped structure design gives it self-positioning ability during assembly, with the bottom facing the part being ground. The grinding block 2 directly participates in the grinding operation. The top is pressed by the base plate 1, and the middle is embedded in the split machine clamping ring 3, forming a three-point clamping structure to improve clamping stability. Two bolts 4 pass through the threaded holes located on both sides of the device. In this embodiment, the number of bolts 4 can be multiple. The base plate 1 and the split machine clamping ring 3 are locked and fixed, realizing the tight connection between the base plate 1 and the split machine clamping ring 3. The clamping force is applied to firmly clamp the diamond grinding block 2. In this embodiment, the split machine clamping ring 3 is a four-part structure made of a whole ring, and each part is fixed with two bolts 4. In other application scenarios, the split machine clamping ring 3 can also be divided into multiple parts or be a whole ring. The number of parts is not fixed, and the number of bolts 4 on the split machine clamping ring 3 is also not fixed.
[0025] In use, insert the diamond grinding blocks 2 one by one into the openings of the clamping ring 3 of the split machine, ensuring that each grinding block is inserted in place and remains vertical. Press the base plate 1 onto the top of the clamping ring 3 from above, and adjust the position so that the threaded holes of the two are aligned. At this time, the base plate 1 presses down on the top of all the diamond grinding blocks 2, so that they are in a clamped state. Select two bolts 4 and insert them into the corresponding threaded holes from the left and right sides of the device, respectively, and tighten them with a wrench or power tool to ensure that there is sufficient clamping force between the base plate 1 and the clamping ring 3 of the split machine, so that all the diamond grinding blocks 2 are firmly fixed. Connect the assembled grinding disc to the main shaft of the equipment motor through the flange or keyway, ensuring that the connection is firm and there is no looseness. After confirming that all the connection parts are correct, start the equipment and make the grinding disc rotate at high speed. The bottom of the diamond grinding blocks 2 will begin to grind the target material.
