Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel production, and specifically refers to an impact-resistant grinding wheel. Background Art

[0002] A grinding wheel is a tool used for grinding and processing, usually composed of abrasive, binder, and pores. During the manufacturing process of the grinding wheel, abrasive particles are mixed with the binder, and then through processes such as pressing and sintering, a grinding tool with a certain shape is formed. The grinding wheel is mainly used for operations such as grinding, cutting, deburring, and polishing of metal or non-metal materials, and has a wide range of applications in fields such as machining, automotive manufacturing, aerospace, and precision instrument manufacturing. According to different processing requirements, grinding wheels with different grit sizes, hardnesses, and shapes can be selected to complete specific tasks.

[0003] During the use of the grinding wheel, various unexpected situations may occur, such as improper operation, accidental collision, or sudden impact of the workpiece. If the grinding wheel is not strong enough, it may crack or shatter when impacted, and the flying fragments may cause serious injury accidents. Therefore, the grinding wheel must be able to withstand a certain degree of external impact without cracking.

[0004] However, in the existing technology, the grinding wheels produced and manufactured often have the following defects including but not limited to: 1. In the existing technology, when the grinding wheel is impacted, not only may it be damaged itself, but its driving components may also shift, resulting in uneven rotation of the grinding wheel, which in turn causes irregular wear, increased vibration and noise, and even causes the grinding wheel to crack under the action of centrifugal force at high speeds, posing a safety hazard to the operator, accelerating equipment wear, and shortening the service life.

[0005] 2. In the existing technology, if the side of the grinding wheel lacks protection, it is prone to damage to the edge of the grinding wheel or overall cracking when impacted. In this case, the grinding wheel may generate flying fragments, posing a serious threat to the operator; at the same time, the unbalanced operation of the grinding wheel will increase vibration, exacerbate equipment wear, and may lead to a decrease in processing accuracy, seriously affecting work safety and production efficiency.

[0006] In view of this, it is necessary to improve the above-mentioned defects.

[0007] The information disclosed in this background art section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of implication that this information constitutes the prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0008] The technical problem to be solved by the utility model is to overcome the above-mentioned defects and provide an impact-resistant grinding wheel.

[0009] To solve the above technical problems, the technical solution provided by the present utility model is as follows:

[0010] An impact-resistant grinding wheel, comprising:

[0011] A grinding wheel body, on both sides of which there are a number of uniformly distributed grooves, and a through hole is provided in the middle of the grinding wheel body;

[0012] A clamping component, which is inserted into the groove, the number of which is adapted to the groove and protrudes from the groove by a part;

[0013] A connecting component, which is connected between two adjacent clamping components, and the connecting component is closely attached and fixedly connected to the grinding wheel body;

[0014] A fixing component, which passes through the grinding wheel body to connect the connecting components on both sides;

[0015] An inner driving component, which is used to connect the grinding wheel body, the clamping component and the connecting component.

[0016] As an improvement, a through screw hole is provided at one end of the groove away from the through hole.

[0017] As an improvement, the groove of the grinding wheel body is communicated with the through hole.

[0018] As an improvement, the clamping component is a connecting rod, and the thickness of the connecting rod is greater than or equal to twice the depth of the groove; the connecting component is a metal surface; the metal surface is fixedly connected to the connecting rod, and the metal surface is fixedly connected to the grinding wheel body through an adhesive.

[0019] As an improvement, the fixing component includes a screw groove opened on the connecting rod, and the fixing component further includes a stud, and the stud is threadedly connected to the screw groove and the screw hole in the groove, and is fastened by nuts provided at both ends thereof.

[0020] As an improvement, the inner driving component includes an inner ring, and the inner ring is fixedly connected to the grinding wheel body, the metal surface and the connecting rod respectively, and a number of tooth protrusions are provided on the inner circumferential surface of the inner ring.

[0021] As an improvement, the grinding wheel body is driven by an additional driving motor, and an engaging portion that engages with and is fixedly connected to the tooth protrusions is provided on the output shaft of the driving motor.

[0022] Compared with traditional technologies, the advantages of the present utility model are as follows: 1. The present utility model designs an internal driving component. By means of the mutual meshing and fixed connection between the tooth protrusions inside the inner ring and the meshing part on the output shaft of the driving motor, the driving of the output shaft on the grinding wheel body is strengthened. That is, even if the output shaft is misaligned with the inner ring when being impacted, it can still continuously output uniform driving force to the grinding wheel body through the meshing method, enabling it to work normally, which makes the grinding wheel rotate evenly and thus avoids potential safety hazards.

[0023] 2. The present utility model opens grooves on both sides of the grinding wheel and, through the connection method of the clamping component and the connecting component, provides protection on both sides of the grinding wheel. When being impacted, the connecting component can bear a certain impact for the grinding wheel, preventing the grinding wheel from being damaged and delaying its service life. Moreover, the tight fit of the clamping component and the connecting component to the grinding wheel disperses the centrifugal force formed during the rotation of the grinding wheel to the clamping component and the connecting component, reducing the probability of its breaking after being vibrated and protecting the grinding wheel well.

[0029] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are only examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0030] Please refer to the attached Figures 1 to 4 of the specification. The present utility model discloses an impact-resistant grinding wheel. In addition to its grinding wheel body 1, the grinding wheel also includes an external structure, which mainly includes a clamping component, a connecting component, a fixing component, and an internal driving component. Among them,

[0031] On both sides of the grinding wheel body 1, a number of uniformly distributed grooves 2 are provided. A through hole 3 is provided in the middle of the grinding wheel body 1. The grooves 2 and the through hole 3 of the grinding wheel body 1 are connected. And a through screw hole is provided at one end of the groove 2 far from the through hole 3. The clamping components are inserted into the grooves 2, the number of which is adapted to the grooves 2 and protrudes from the grooves 2 by a part; during use, the grinding wheel body 1 rotates under the driving force. At the same time, the clamping components also rotate under the same driving force. By clamping the clamping components into the grooves 2, the rotation of the grinding wheel body 1 can be assisted, so that the rotation force of the grinding wheel body 1 is more uniform. Then the connecting components are connected between two adjacent clamping components. The connecting components and the grinding wheel body 1 are closely attached and fixedly connected; and the two side connecting components are connected by a fixing component passing through the grinding wheel body 1 to provide external protection for the grinding wheel body 1. Finally, the internal driving component is used to connect the grinding wheel body 1, the clamping components and the connecting components.

[0032] In order to describe in detail the specific working principle of the present invention, in a preferred embodiment of the present invention, the above-mentioned clamping component is a connecting rod 4, and the thickness of the connecting rod 4 is greater than or equal to twice the depth of the groove 2; the connecting component is a metal surface 5; the metal surface 5 and the connecting rod 4 are fixedly connected, and the metal surface 5 and the grinding wheel body 1 are fixedly connected by an adhesive. Therefore, when being impacted, the metal surface 5 and the connecting rod 4 can first contact the impact force, and convert and evenly disperse the impact force through their own structures, avoiding the direct sharp contact of the impact force with the grinding wheel body 1, so as to cause the risk of breakage. At the same time, when the grinding wheel body 1 rotates, since the metal surface 5 and its side surface are closely attached by an adhesive, therefore, when rotating at a high speed, a centrifugal force will be generated at the edge of the grinding wheel body 1. And in a preferred embodiment of the present invention, the centrifugal force will be dispersed in the way of the metal surface 5 to make the force evenly distributed and not easily damaged.

[0033] The above components are fixed by fixing components. The fixing components include a screw groove 6 formed on the connecting rod 4. The fixing components also include a stud 7. The stud 7 is threadedly connected to the screw groove 6 and the screw hole in the groove 2, and is fastened by nuts 8 provided at both ends thereof. By screwing the stud 7 and the nuts 8, different degrees of close contact and fixation can be achieved. Finally, the assembled grinding wheel body 1 and its external structure are driven by an internal driving component and an additional driving motor. Among them, the internal driving component includes an inner ring 9. The inner ring 9 is fixedly connected to the grinding wheel body 1, the metal surface 5, and the connecting rod 4 respectively. A plurality of tooth protrusions 10 are provided on the inner circumferential surface of the inner ring 9. And a meshing portion meshing with the tooth protrusions 10 is provided on the output shaft of the driving motor. The meshing portion is fixedly connected to the tooth protrusions 10 and the reverse at the same time. Therefore, when the output shaft of the motor is energized and rotates, the meshing portion will drive the tooth protrusions 10, thereby driving the grinding wheel body 1 and each component thereon to rotate, so as to work. And when the equipment body is impacted and the connection between the meshing portion and the tooth protrusions 10 is misaligned, through the meshing between them, the grinding wheel body 1 can also rotate under stable force within a certain time range without being broken. Until before the failure, the user can stop the operation of the equipment, perform maintenance and replacement, avoiding the injury caused by the breakage after being impacted during high-speed rotation.

[0034] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the gist of the present invention, they shall fall within the protection scope of the present invention.
