Description

Technical Field

[0001] This utility model relates to the field of abrasive tool reinforcement technology, and in particular to a reinforcement device for abrasive tool grinding. Background Technology

[0002] Abrasives and grinding tools are a general term for abrasives and grinding tools, including abrasive products and grinding tool products. Abrasives and grinding tools are often referred to as the teeth of industry. During grinding, abrasives or grinding tools are often used as grinding tools to machine parts to meet certain technical requirements.

[0003] Commonly used abrasive grinding tools include cutting discs and grinding wheels, louvered discs, quick-change grinding discs, grinding rolls, bonded grinding wheels, multi-bladed grinding rings and sandpaper grinding rings, non-bonded multi-bladed grinding wheels, multi-bladed grinding wheels, sandpaper rolls and felt rolls, and tungsten carbide rotary files. Most of the existing grinding tools are fixed to the output shaft of the grinding machine with multiple bolts, which makes the replacement process complicated, increases the workload, and reduces the efficiency of grinding.

[0004] Chinese utility model patent application number CN202322769616.2 describes a reinforcing device for grinding abrasive tools. It uses a movable block 403 with a threaded through-hole at its center connected to the threaded surface of a drive column 402. This allows the abrasive tool to be inserted through the drive column, with one side of the tool adhering to the surface of a fixing plate. Rotating the movable block then fixes the tool in place, making tool fixation easier and improving efficiency. The fixing component is then inserted into the drive groove, and the guide column is rotated, causing four top blocks to tightly press against the inner wall of the abrasive tool, further reinforcing the tool and preventing wobbling during rotation, thus improving stability. However, this reinforcing device requires first rotating the drive column to separate the top blocks from the inner wall of the abrasive tool, and then rotating the movable block again until it is removed from the drive column 402 to complete the disassembly. This requires two rotations to disassemble the abrasive tool, which does not significantly improve the efficiency of tool disassembly and installation, and reduces the reliability of the reinforcing device. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforcement device for abrasive grinding, so as to solve the problem mentioned in the background art that the existing reinforcement devices for abrasive grinding are troublesome and laborious to disassemble and install, thus reducing the grinding efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reinforcing device for grinding abrasive tools, comprising a rotating shaft, a limiting ring fixedly sleeved on the outer circumferential surface of the rotating shaft, a fixed clamping plate fixedly connected to the left side of the limiting ring, a grinding tool movably sleeved on the outer circumferential surface of the rotating shaft, a movable clamping plate movably sleeved on the outer circumferential surface of the rotating shaft, the movable clamping plate being located to the left side of the grinding tool, the movable clamping plate and the fixed clamping plate clamping the grinding tool, an external thread being provided on the outer circumferential surface of the left end portion of the rotating shaft, a threaded sleeve being threaded onto the left end of the rotating shaft, the right side of the threaded sleeve being tightly abutting against the left side of the movable clamping plate, and a reinforcing component being provided on the rotating shaft;

[0007] The reinforcement components are used to enhance the connection strength of the grinding wheel on the shaft.

[0008] Preferably, the reinforcing assembly includes multiple movable slots formed at equal angles on the left side of the fixed clamping plate. Two guide rods are symmetrically fixedly connected to the inner wall of each movable slot away from the axis of rotation. A top block is movably sleeved at one end of each guide rod near the axis of rotation. A first elastic element is fixedly connected between the side of the top block away from the axis of rotation and the inner wall of the movable slot. The reinforcing assembly also includes multiple top cavities formed at equal angles on the right side of the grinding wheel. The sides of the multiple top blocks away from the axis of rotation and the inner walls of the multiple top cavities away from the axis of rotation are respectively pressed against the inner walls of the multiple top cavities away from the axis of rotation. The reinforcing assembly also includes a driving mechanism provided on the rotating shaft. The driving mechanism is used to drive the multiple top blocks to move in a direction away from or near the axis of rotation. The advantage of this arrangement is that it can enhance the connection between the fixed clamping plate and the grinding wheel, ensure the stability of the grinding wheel during grinding, and thus improve the grinding effect and quality.

[0009] Preferably, the driving mechanism includes a frustum-shaped push block movably sleeved on the outer circumferential surface of the rotating shaft. The inner sidewall of the fixed clamping plate is frustum-shaped and fits against the frustum surface of the push block. One end of each of the multiple moving slots near the rotating shaft passes through the inner sidewall of the fixed clamping plate. The bottom surfaces of each of the multiple top blocks abut against the frustum surface of the push block. The driving mechanism also includes a sleeve movably sleeved on the rotating shaft. The right end of the sleeve is fixedly connected to the left side of the push block. The right side of the threaded sleeve abuts against the left end face of the sleeve. The advantage of this arrangement is that it makes the reinforcement operation simple and quick, improves the practicality of the reinforcement device, and effectively improves the efficiency of grinding.

[0010] Preferably, the reinforcement assembly further includes multiple insert plates fixedly connected at equal angles to the sides of multiple top blocks away from the rotating shaft. The reinforcement assembly also includes multiple limiting grooves formed at equal angles on the inner sidewalls of multiple top cavities away from the rotating shaft. The multiple insert plates can be inserted into the multiple limiting grooves respectively. The advantage of this arrangement is that, by inserting the insert plates into the limiting grooves as the top blocks move, the connection between the fixing clamp and the mold can be further strengthened in conjunction with the top blocks, thereby further improving the reliability of the reinforcement device.

[0011] Preferably, a cavity is formed on the left side of the movable clamping plate, and a thrust plate is movably inserted into the cavity. The right side of the thrust plate is fixedly connected to the left end of the sleeve. The thrust plate is movably sleeved on the outer circumferential surface of the rotating shaft, and the right side of the threaded sleeve abuts against the left side of the thrust plate. The advantage of this arrangement is that the thrust plate and the cavity provide a limiting structure between the movable clamping plate and the sleeve, which further ensures the firmness of the connection between the mold and the rotating shaft.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, by using the provided screw sleeve, the screw sleeve is moved to the right along the axis of rotation until the screw sleeve pushes the movable clamping plate to press against the left side of the grinding tool, which can quickly complete the fixing operation of the grinding tool. At the same time, the reinforcement component completes the reinforcement operation of the grinding tool as the screw sleeve clamps and fixes the grinding tool, thereby improving the operation convenience and reliability of the reinforcement device.

[0014] 2. In this utility model, by setting a top block, a top cavity, an insert plate, and a limiting groove, the insert plate can be inserted into the limiting groove as the top block moves, which can work with the top block to further enhance the connection between the fixing clamp and the mold, and further improve the reliability of the reinforcement device.

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.

[0024] Example 1

[0025] Please refer to Figures 1-6 The device shown is a reinforcing device for grinding abrasive tools, including a rotating shaft 1. A limiting ring 2 is fixedly sleeved on the outer circumferential surface of the rotating shaft 1. A fixed clamping plate 3 is fixedly connected to the left side of the limiting ring 2. An abrasive tool 4 is movably sleeved on the outer circumferential surface of the rotating shaft 1. A movable clamping plate 5 is movably sleeved on the outer circumferential surface of the rotating shaft 1. The movable clamping plate 5 is located to the left side of the abrasive tool 4. The movable clamping plate 5 and the fixed clamping plate 3 clamp the abrasive tool 4. An external thread is opened on the outer circumferential surface of the left end of the rotating shaft 1. A threaded sleeve 6 is threaded on the left end of the rotating shaft 1. The right side of the threaded sleeve 6 is tightly pressed against the left side of the movable clamping plate 5. A reinforcing component 7 is provided on the rotating shaft 1.

[0026] Reinforcing component 7 is used to enhance the connection strength of the mold 4 to the shaft 1;

[0027] The left side of the fixed clamping plate 3 is provided with multiple insertion holes 61 in a ring shape at equal angles. The side of the grinding mold 4 is provided with multiple through holes in a ring shape at equal angles. The right side of the movable clamping plate 5 is fixedly connected with multiple insertion rods 62 in a ring shape at equal angles. The multiple insertion rods 62 pass through the multiple through holes and are movably inserted into the multiple insertion holes 61. In this way, the grinding mold 4 can be radially limited, further improving the connection firmness of the grinding mold 4 on the rotating shaft 1.

[0028] A polishing layer is fixedly fitted onto the outer circumferential surface of the grinding mold 4.

[0029] refer to Figures 2-6 The reinforcing component 7 includes multiple movable slots 71 that are opened at equal angles in an annular shape on the left side of the fixed clamping plate 3. Two guide rods 72 are symmetrically fixedly connected to the inner side wall of the movable slots 71 away from the axis of the rotating shaft 1. A top block 73 is movably sleeved at one end of the two guide rods 72 near the axis of the rotating shaft 1. A first elastic element is fixedly connected between the side of the top block 73 away from the axis of the rotating shaft 1 and the inner side wall of the movable slot 71. The reinforcing component 7 also includes multiple top cavities 74 that are opened at equal angles in an annular shape on the right side of the mold 4. The sides of the multiple top blocks 73 away from the axis of the rotating shaft 1 and the inner side walls of the multiple top cavities 74 away from the axis of the rotating shaft 1 are respectively pressed tightly against the inner side walls of the multiple top cavities 74 away from the axis of the rotating shaft 1. The reinforcing component 7 also includes a driving mechanism 75 provided on the rotating shaft 1. The driving mechanism 75 is used to drive the multiple top blocks 73 to move in a direction away from or close to the axis of the rotating shaft 1.

[0030] Specifically, the drive mechanism 75 overcomes the elastic force of the first elastic element and drives multiple top blocks 73 to move away from the rotating shaft 1 until they are pressed tightly against the inner sidewalls of multiple top cavities 74 away from the rotating shaft 1. This can enhance the connection between the fixed clamping plate 3 and the grinding wheel 4, ensure the stability of the grinding wheel 4 during grinding, and thus improve the grinding effect and quality of the grinding wheel 4.

[0031] refer to Figures 2-4 The drive mechanism 75 includes a frustum-shaped push block 751 that is movably sleeved on the outer circumferential surface of the rotating shaft 1. The inner sidewall of the fixed clamping plate 3 is a frustum shape that fits against the frustum surface of the push block 751. One end of a plurality of moving slots 71 near the rotating shaft 1 passes through the inner sidewall of the fixed clamping plate 3. The bottom surfaces of a plurality of top blocks 73 all abut against the frustum surface of the push block 751. The drive mechanism 75 also includes a sleeve 752 that is movably sleeved on the rotating shaft 1. The right end of the sleeve 752 is fixedly connected to the left side of the push block 751. The right side of the screw sleeve 6 is tightly abutted against the left end face of the sleeve 752.

[0032] Specifically, simply rotate the screw sleeve 6 to the right along the axis of the rotating shaft 1 until the movable clamping plate 5 and the fixed clamping plate 3 clamp the grinding tool 4. At the same time, the screw sleeve 6 also presses the left end of the sleeve 752 tightly against the shaft. This allows the push block 751 to push the top block 73 to press tightly against the inner wall of the top cavity 74 away from the rotating shaft 1, making the reinforcement operation simple and quick, improving the practicality of the reinforcement device, and effectively improving the efficiency of grinding.

[0033] refer to Figure 5 The reinforcing component 7 also includes multiple insert plates 76 that are fixedly connected in an annular shape at equal angles to the sides of multiple top blocks 73 away from the rotating shaft 1. The reinforcing component 7 also includes multiple limiting grooves 77 that are opened in an annular shape at equal angles on the inner sidewalls of multiple top cavities 74 away from the rotating shaft 1. The multiple insert plates 76 can be inserted into the multiple limiting grooves 77 respectively.

[0034] Specifically, by inserting the insert plate 76 into the limiting groove 77 as the top block 73 moves, the connection between the fixing clamp 3 and the mold 4 can be further strengthened in conjunction with the top block 73, thereby further improving the reliability of the reinforcement device.

[0035] The right side of the insert plate 76 is an inclined surface that tilts away from the fixed clamping plate 3. The inner wall of the right side of the limiting groove 77 is located on the inclined surface that matches the right side of the insert plate 76. Through the contact between the two inclined surfaces, the fixed clamping plate 3 and the grinding mold 4 can be simultaneously limited radially and axially, thereby further improving the connection strength of the grinding mold 4 on the rotating shaft 1.

[0036] refer to Figures 2-4 A cavity 8 is opened on the left side of the movable clamping plate 5. A thrust plate 9 is movably inserted into the cavity 8. The right side of the thrust plate 9 is fixedly connected to the left end of the sleeve 752. The thrust plate 9 is movably sleeved on the outer circumferential surface of the rotating shaft 1. The right side of the screw sleeve 6 is tightly pressed against the left side of the thrust plate 9.

[0037] Specifically, the thrust plate 9, in conjunction with the cavity 8, provides a limiting structure between the movable clamping plate 5 and the sleeve 752, thereby further ensuring the firmness of the connection between the mold 4 and the rotating shaft 1.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
