Description
Technical Field
[0001] This utility model relates to the field of grinding and polishing technology, and in particular to a novel silicone grinding head. Background Technology
[0002] Silicone grinding heads are made of high-grade silicone raw materials and processed with special techniques, resulting in excellent elasticity and wear resistance. They are suitable for various grinding scenarios, protect the integrity of workpieces, are simple and safe to operate, operate without noise, improve the working environment, reduce replacement frequency, and save costs, making them the preferred tool for various industries.
[0003] Traditional grinding heads operate by using the friction between the abrasive and the workpiece surface through a high-speed rotating grinding head to cut and remove material. However, traditional grinding heads suffer from low grinding efficiency, high heat generation, poor heat dissipation, leading to workpiece thermal deformation, rapid head wear, unstable processing accuracy, and other drawbacks. Existing grinding head technologies employ advanced drive methods combined with automated control, improving grinding efficiency and consistency. However, in practical use, these devices lack cooling mechanisms. Without this structure, the abrasive temperature becomes excessively high during processing, affecting processing quality, shortening equipment lifespan, and even causing operational safety issues. Therefore, a novel silicone grinding head is proposed to address these problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a novel silicone grinding head, which aims to improve the problem that the temperature of the abrasive is too high during the processing, affecting the processing quality.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel silicone grinding head, comprising a connecting column, a fixing mechanism provided at the bottom of the outer wall of the connecting column, an abrasive fixedly connected to the outer wall of the connecting column, a cooling mechanism provided on the inner wall of the abrasive, and a fixing cavity opened on the outer wall of the abrasive. The cooling mechanism includes a baffle plate, the outer wall of which is fixedly connected to the inner wall of the abrasive. The inner wall of the abrasive has a cooling chamber, a flow guide hole one, a flow guide hole two, a flow guide cavity, and a cooling chamber. The bottom of the outer wall of the baffle plate has a return groove. The inner wall of the abrasive is equipped with a sealing component, and a thermal component is fixedly connected to the inner wall of the return groove.
[0006] As a further description of the above technical solution: The fixing mechanism includes a connecting piece, the outer wall of which is fixedly connected to the inner wall of the abrasive, a locking post fixedly connected to the bottom of the outer wall of the connecting piece, a limit groove opened at the bottom of the outer wall of the abrasive, and an inlet hole opened at the top of the outer wall of the abrasive.
[0007] As a further description of the above technical solution: The fixing mechanism also includes an insert block, the top of the outer wall of the insert block is fixedly connected to the bottom of the outer wall of the connecting column, and the outer wall of the insert block is provided with a locking groove.
[0008] As a further description of the above technical solution: The sealing assembly includes a sealing ring, the inner wall of which is fixedly connected to the outer wall of the baffle, and a sealing groove is formed on the inner wall of the abrasive.
[0009] As a further description of the above technical solution: The thermal component includes a first thermal deformation plate, the outer wall of which is fixedly connected to the inner wall of the abrasive, and a second thermal deformation plate is fixedly connected to the inner wall of the abrasive.
[0010] As a further description of the above technical solution: A handle is fixedly connected to the top of the outer wall of the connecting column, and the top of the outer wall of the handle has a beveled angle.
[0011] As a further description of the above technical solution: The diameter of the connecting column is consistent with the diameter of the limiting groove, and the outer wall of the embedded block is fixedly connected to the inner wall of the abrasive.
[0012] As a further description of the above technical solution: The outer wall of the baffle is fixedly connected to the inner wall of the sealing ring, and the first and second heat-deformation plates are symmetrically distributed along the central axis of the abrasive.
[0013] This utility model has the following beneficial effects: 1. In this utility model, the cooling chamber stores coolant. During operation, the coolant enters the guiding chamber through the first guiding hole to initially cool the edge of the abrasive. Then, it flows into the cooling chamber in the high-temperature area through the second guiding hole, where it rapidly vaporizes and absorbs a large amount of heat. The vaporized fluoride returns to the cooling chamber through the channel formed by the contraction of the heat-deformed sheet and the return groove, achieving continuous and efficient cooling and effectively maintaining the stable working temperature of the abrasive.
[0014] 2. In this utility model, the abrasive and the locking post are firmly connected by the connecting piece. The locking post and the embedded block adopt an interference fit, which significantly enhances the overall structural rigidity. The limiting groove effectively restricts the bottom displacement of the abrasive and prevents it from shifting during high-speed grinding. The locking groove on the embedded block ensures close contact with the locking post. Assembly is carried out from the top inlet hole. The whole design realizes the tight fixation of the internal components and greatly improves the stability and operation accuracy of the grinding process. Attached Figure Description

Detailed Implementation
[0017] 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.
[0018] Reference Figure 1 , Figure 2 and Figure 4 The present invention provides an embodiment of a novel silicone grinding head, comprising a connecting post 1 for connecting key parts of the grinding head body, a fixing mechanism 5 for the bottom of the outer wall of the connecting post 1, and an abrasive 2 fixedly connected to the outer wall of the connecting post 1, which serves as the cutting body and is directly responsible for grinding, cutting and polishing the workpiece. The abrasive 2 is made of TPE elastomer. Using a type A hardness tester, the Shore hardness value obtained by pressing the sample of this abrasive 2 for fifteen seconds is between 48 and 53. A cooling mechanism 4 is provided on the inner wall of the abrasive 2, and a fixing cavity 3 is opened on the outer wall of the abrasive 2. The cooling mechanism 4 includes a baffle 401 to prevent leakage of the fluorinated coolant. The outer wall of the baffle 401 is fixedly connected to the inner wall of the abrasive 2. The inner wall of the abrasive 2 has a cooling cavity 404 for holding a certain volume of fluorinated coolant to prepare for subsequent cooling operations. The inner wall of the abrasive 2 has a first guide hole 405, a second guide hole 407, and a guide cavity 406. A cooling cavity 408 is formed on the inner wall of the abrasive 2, and a return groove 409 is formed on the bottom of the outer wall of the baffle 401. The fluorinated coolant flows through the first guide hole 405 to the guide cavity 406. The guide cavity 406 is distributed in four directions on the bottom edge of the abrasive 2. When the fluorinated coolant flows to this location, the temperature is effectively reduced first. Then, it flows through the second guide hole 407 to the cooling cavity 408. The cooling cavity 408 is located above the limiting groove 505, and its position is where the temperature is highest. At the high point, the fluorinated coolant cools the temperature here to the normal threshold and then rapidly vaporizes and returns to the cooling chamber 404 through the return channel 409. Due to the high vaporization temperature, the first heat deformation plate 4031 and the second heat deformation plate 4032 are rapidly contracted due to the temperature, providing a return channel for the vaporized fluoride. The inner wall of the abrasive 2 is provided with a sealing component 402, which includes a sealing ring 4021, which plays a certain sealing role. The inner wall of the sealing ring 4021 is fixedly connected to the outer wall of the baffle 401. The inner wall of the abrasive 2 is provided with a sealing groove 4022. The inner wall of the return channel 409 is fixedly connected with a thermal component 403, which includes a first heat deformation plate 4031. The outer wall of the first heat deformation plate 4031 is fixedly connected to the inner wall of the abrasive 2. The inner wall of the abrasive 2 is fixedly connected with a second heat deformation plate 4032. The entire structure effectively relieves the continuous high temperature generated by the operation of the abrasive 2. Specifically, the baffle 401 is used to prevent leakage of the fluorinated coolant. Its outer wall is fixedly connected to the inner wall of the abrasive 2. The abrasive 2 has a cooling chamber 404 inside, which stores a certain volume of fluorinated coolant to provide a medium for continuous cooling of the structure. At the same time, the abrasive 2 is also machined with a first guide hole 405, a second guide hole 407, a guide cavity 406, and a cooling cavity 408. A return groove 409 is arranged on the bottom outer wall of the baffle 401. During operation, the fluorinated coolant enters the guide cavity 406 from the first guide hole 405. This cavity covers the bottom edge area of the abrasive 2, which can achieve initial cooling of this part, followed by further cooling. The coolant enters the cooling chamber 408 through the second guide hole 407. This area is a high-temperature part of the structure. The coolant completes heat exchange and rapidly vaporizes here, keeping the temperature within a reasonable range. The gaseous fluoride then returns to the cooling chamber 404 through the return groove 409. Due to the high vaporization temperature, the first thermal deformation plate 4031 and the second thermal deformation plate 4032 shrink when heated, forming a gas return channel. The sealing ring 4021 is in contact with the outer wall of the baffle 401 and is embedded in the sealing groove 4022, improving the overall sealing performance. The entire mechanism achieves efficient control and heat dissipation of the high working temperature of the abrasive 2 through the circulation and phase change process of the coolant.
[0019] Reference Figure 1 , Figure 2 and Figure 3 The fixing mechanism 5 includes a connecting piece 501, which fixes the inner wall of the abrasive 2 and the locking post 502 together to ensure its stability. The outer wall of the connecting piece 501 is fixedly connected to the inner wall of the abrasive 2. The bottom of the outer wall of the connecting piece 501 is fixedly connected to the locking post 502. The locking post 502 and the insert block 503 are interference-fitted to improve the stability of the entire workpiece during operation. A limiting groove 505 is formed at the bottom of the outer wall of the abrasive 2 to limit and fix the bottom of the abrasive 2. The depth of the limiting groove 505 is determined according to the actual situation. The hardness of the abrasive material can be flexibly changed between one millimeter and seven millimeters to avoid uneven grinding during high-speed grinding. The top of the outer wall of the abrasive 2 is provided with an inlet hole 506. The fixing mechanism 5 also includes an insert block 503. The top of the outer wall of the insert block 503 is fixedly connected to the bottom of the outer wall of the connecting column 1. The outer wall of the insert block 503 is provided with a locking groove 504, which is the direct medium for the locking column 502 to contact the insert block 503. The entire structure realizes the tight fixing of the various components inside the workpiece and improves the stability during grinding. Specifically, the connecting piece 501 is used to connect the inner wall of the abrasive 2 and the locking post 502 to form an integral structure to enhance stability. The outer wall of the connecting piece 501 is fixedly connected to the inner wall of the abrasive 2, and its bottom is connected to the locking post 502. The locking post 502 is combined with the embedded block 503 through an interference fit, which significantly improves the firmness of the structure during operation. The bottom of the outer wall of the abrasive 2 is provided with a limiting groove 505 to limit the movement of the bottom of the abrasive 2 and prevent displacement during high-speed grinding. The top of the outer wall of the abrasive 2 is provided with an inlet hole 506 for easy assembly and maintenance. The top outer wall of the embedded block 503 is connected to the bottom outer wall of the connecting post 1, and its surface is machined with a locking groove 504, which serves as the interface for direct contact with the locking post 502 to ensure reliable force. The whole structure effectively improves the stability and overall performance of the grinding operation.
[0020] Reference Figure 1 , Figure 2 and Figure 5 A handle 6 is fixedly connected to the top of the outer wall of the connecting column 1, which is responsible for connecting the grinding head with the electric drill, angle grinder and grinding machine. The top of the outer wall of the handle 6 is provided with a bevel angle 7, which is conducive to maintaining a stable installation structure with the output end. The diameter of the connecting column 1 is consistent with the diameter of the limiting groove 505. The outer wall of the embedded block 503 is fixedly connected to the inner wall of the abrasive 2. The outer wall of the baffle 401 is fixedly connected to the inner wall of the sealing ring 4021. The first heat deformation plate 4031 and the second heat deformation plate 4032 are symmetrically distributed along the central axis of the abrasive 2. Specifically, the handle 6 is fixed to the top of the connecting post 1 and is used to connect the electric drill, angle grinder and polisher. The bevel angle 7 at the top of the handle ensures that it forms a stable installation structure with the output end. The diameter of the connecting post 1 is consistent with the limiting groove 505. The embedded block 503 is fixedly connected to the inner wall of the abrasive 2. The baffle 401 is sealed by the sealing ring 4021. The first heat deformation plate 4031 and the second heat deformation plate 4032 are symmetrically distributed along the central axis of the abrasive 2 to jointly improve the overall stability of the structure.
[0021] Working principle: First, the cooling chamber 404 is used to store fluorinated coolant. During the operation of the structure, the coolant enters the guide chamber 406 through the guide hole 1 405 to perform preliminary cooling on the edge area of the abrasive 2. Then, it flows into the cooling chamber 408 in the high-temperature area through the guide hole 2 407, where it rapidly vaporizes and absorbs a large amount of heat energy. The vaporized fluoride returns to the cooling chamber 404 through the return groove 409 through the channel formed by the thermal deformation plate 1 4031 and the thermal deformation plate 2 4032 due to heat contraction. This realizes the cyclic cooling process and continuously and efficiently controls the temperature fluctuation of the abrasive 2 under working conditions. Furthermore, the fixing mechanism 5 securely connects the abrasive 2 to the engaging post 502 via the connecting piece 501. The engaging post 502 and the insert block 503 are interference-fitted, which significantly improves the stability of the overall structure. The limiting groove 505 effectively restricts the movement of the bottom of the abrasive 2, preventing positional shift during high-speed grinding operations. The engaging groove 504 on the insert block 503 ensures close contact between it and the engaging post 502. The assembly operation is completed through the top inlet hole 506. The entire structure achieves tight fixation between internal components, thereby greatly enhancing the stability of the grinding process.
