Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a grinding wheel anti-splash device and a grinding wheel machine. Background Art

[0002] In the field of machining, the tool will wear out after being used for a certain period of time, and usually a grinding machine is needed to grind the tool. The tool can continue to be used normally after grinding, which improves efficiency and reduces costs.

[0003] However, when using a grinding machine for grinding, since the existing grinding machines basically have no protective devices, the splashes generated when the grinding machine is used will splash everywhere. These splashes can easily splash onto the eyes, skin and other parts of the operator, causing damage to the eyes, skin and other parts of the human body, leading to safety accidents.

[0004] Therefore, the prior art still needs to be improved and developed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of this application is to provide a grinding wheel anti-splash device and a grinding machine, aiming to prevent injuries caused by splashes when the grinding machine is grinding and ensure safety.

[0006] The technical solution adopted by the present application to solve the technical problem is as follows: a grinding wheel splash prevention device, comprising:

[0007] A bracket, the bracket is disc-shaped and has an operation port;

[0008] A grinding wheel, the grinding wheel being rotatably mounted in the bracket;

[0009] A protection component, the protection component is rotatably mounted on the top of the bracket;

[0010] A rotating shaft is inserted into the bracket and the protection component.

[0011] Furthermore, the protection component includes a protective cover, which is rotatably mounted on the rotating shaft to shield the operating port.

[0012] Furthermore, the protection component also includes an adjusting knob, and the adjusting knob is sleeved on the rotating shaft and fits the protective cover.

[0030] The utility model provides a grinding wheel anti-splash device and a grinding machine. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0031] like Figures 1 to 3As shown, a grinding wheel anti-splash device is intended to prevent injuries caused by splashes when the grinding machine is grinding, ensuring safety. The grinding wheel anti-splash device includes a bracket 1, a grinding wheel 2, a protective component 4 and a rotating shaft 3. The bracket 1 is disc-shaped and has an installation cavity inside for the installation of the grinding wheel 2. The grinding wheel 2 is rotatably installed in the installation cavity. When the grinding machine is running, the grinding wheel 2 rotates in the grinding machine, and the tool that needs to be polished is polished by the rotation of the grinding wheel 2. At the same time, the bracket 1 is also provided with an operating port, so that the grinding wheel 2 installed in the turntable is exposed, so that the grinding wheel 2 can directly contact the tool that needs to be polished, and then when the grinding wheel 2 rotates, the tool that needs to be polished is brought close to the operating port, and the rotating grinding wheel 2 is in direct contact with the tool, so that the grinding wheel 2 can polish the tool. The protection component 4 is rotatably mounted on the top of the bracket 1. The protection component 4 is in an arc shape as a whole. By rotating the protection component 4 around the top of the bracket 1, the protection component 4 is rotated toward the operation port or away from the operation port, thereby adjusting the shielding range of the protection component 4 for the operation port, ensuring that when the grinding wheel 2 is grinding the tool, the protection component 4 can block the splash generated when the tool is grinding, and does not affect the grinding of the tool by the grinding wheel 2. At the same time, it is also convenient for the operator to check the grinding status of the tool in real time. When the grinding machine is not running, the protection component 4 can better protect the grinding wheel 2 and the operation port, and avoid the grinding wheel 2 from being damaged and affecting the grinding of the tool by the grinding machine. The rotating shaft 3 penetrates the bracket 1 and the protection component 4, and the rotating shaft 3 is passed into the top of the bracket 1. The left and right sides of one end of the protection component 4 are respectively rotatably mounted on the rotating shaft 3, so that the protection component 4 can rotate around the rotating shaft 3, thereby adjusting the shielding range of the protection component 4 for the operation port and the grinding wheel 2.

[0032] In order to achieve the shielding of the operating port and the grinding wheel 2 by the protective component 4, the protective component 4 includes a protective cover 41. The protective cover 41 is arc-shaped and is rotatably installed on the rotating shaft 3 to shield the operating port and the grinding wheel 2. Specifically, when the tool needs to be grinded using a grinding machine, the protective cover 41 is rotated to rotate it away from the operating port to expose the operating port and the grinding wheel 2, so that the grinding wheel 2 can directly contact the tool to be grinded, ensuring that the grinding wheel 2 can grind the tool. At the same time, the protective cover 41 is only rotated to a certain angle so that the operating port and the grinding wheel 2 are exposed to a range that just ensures that the grinding wheel 2 grinds the tool, and ensures that the splashes generated when the grinding wheel 2 is grinding are completely blocked by the protective cover 41 to prevent the splashes from flying to the operator or other locations, thereby ensuring safety and preventing the operator from being injured. When the grinding wheel 2 has completed the grinding process of the tool, the protective cover 41 is rotated towards the operating port so that the protective cover 41 covers the operating port and the grinding wheel 2 to prevent the grinding wheel 2 from being damaged, maintain the integrity of the grinding machine, and ensure that the grinding machine can be used normally in the future, thereby extending the service life of the grinding machine.

[0033] When the grinding wheel 2 is grinding the tool, the protective cover 41 needs to be fixed to prevent the protective cover 41 from rotating in the direction of the grinding wheel 2 when the grinding wheel 2 rotates, thereby damaging the grinding wheel 2. Therefore, in the present application, the protection component 4 also includes an adjusting knob 42, which is sleeved on the rotating shaft 3 and fits with the protective cover 41. The adjusting knob 42 is used to adjust whether the protective cover 41 can rotate around the rotating shaft 3. Specifically, for example, when the grinding machine is needed to grind the tool, the protective cover 41 is rotated to a certain angle away from the operating port, and the adjusting knob 42 is rotated so that the adjusting knob 42 is rotated in a direction close to the bracket 1, and the protective cover 41 is locked on the bracket 1, limiting the rotation of the protective cover 41 and preventing the protective cover 41 from falling on the grinding wheel 2, thereby maintaining the normal rotation of the grinding wheel 2. When the protective cover 41 cannot rotate under the action of the adjusting knob 42, the grinding wheel 2 is allowed to rotate and the tool is ground. When the grinding wheel 2 has finished grinding the tool, first stop the rotation of the grinding wheel 2, and then turn the adjusting knob 42 to make the adjusting knob 42 rotate away from the bracket 1, unlock the protective cover 41, so that the protective cover 41 can rotate again, and then turn the protective cover 41 toward the operating port to cover the operating port and the grinding wheel 2, so that the protective cover 41 continues to protect the grinder and the grinding wheel 2.

[0034] Furthermore, in order to prevent the grinding wheel 2 from causing accidental injuries, the protection component 4 also includes a sensor 43, which is installed on the protective cover 41. For example, when the grinding wheel 2 is rotating, if a person approaches the grinding wheel 2, the sensor 43 senses that a person is approaching, and then the sensor 43 controls the motor that drives the grinding wheel 2 to rotate, and randomly controls the motor that drives the grinding wheel 2 to stop running, thereby stopping the grinding wheel 2 from rotating, thereby preventing the rotation of the grinding wheel 2 from causing harm to the person, thereby preventing the occurrence of safety accidents.

[0035] In addition, in other embodiments, the automatic operation of the grinding machine can also be controlled by the sensor 43, that is, when the tool to be polished approaches the grinding machine, the protective cover 41 automatically rotates to expose the operation port and the grinding wheel 2, and then the grinding wheel 2 starts to rotate. At this time, it is only necessary to manually contact the tool to be polished with the grinding wheel 2, and the grinding wheel 2 starts to grind the tool, and there is no need to manually adjust the protective cover 41 and turn on the grinding wheel 2 to grind the tool. Therefore, in order to achieve this function, the present embodiment also includes a traction component 5, which is connected to the protective cover 41 in a transmission manner, and the traction component 5 is also electrically connected to the sensor 43. When the sensor 43 detects that the tool is approaching, it sends a signal to the traction component 5, and the traction component 5 controls the protective cover 41 to rotate in a direction away from the operation port to expose the grinding wheel 2, so that the grinding wheel 2 can directly contact the tool to be polished. At the same time, the sensor 43 sends a signal to the motor that controls the rotation of the grinding wheel 2, so that the motor controls the rotation of the grinding wheel 2, and when the tool contacts the grinding wheel 2, the grinding wheel 2 can grind the tool.

[0036] Specifically, the traction assembly 5 includes a traction motor 51, which is connected to the protective cover 41 by transmission, and the traction motor 51 is electrically connected to the sensor 43. The protection assembly 4 also includes a traction belt 52, one end of the traction belt 52 is connected to the traction motor 51, and the other end of the traction belt 52 is connected to the protective cover 41. Therefore, when it is necessary to allow the grinder to automatically start running and grind the tool after the tool is close to the grinder, the tool must first be brought close to the grinder. When the sensor 43 senses that the tool is close, the sensor 43 immediately sends a signal to the traction motor 51, and the traction motor 51 drives the traction belt 52 to rotate, and then the traction belt 52 pulls the protective cover 41 away from the grinder. The operating port is rotated, and when the protective cover 41 rotates to the specified position, the grinding wheel 2 starts to rotate again. At this time, the tool is moved closer to the grinding wheel 2 to allow the grinding wheel 2 to grind the tool. When the grinding is completed, the tool is away from the grinding wheel 2. At this time, the sensor 43 detects that the tool has moved away from the grinding machine, and sends a signal to the motor that controls the rotation of the grinding wheel 2 to control the grinding wheel 2 to stop rotating. At the same time, the traction motor 51 drives the traction belt 52 to rotate again, so that the traction belt 52 drives the protective cover 41 to rotate in the direction close to the operating port, until the protective cover 41 rotates to the initial position, the traction motor 51 stops running, and the protective cover 41 covers the operating port and the grinding wheel 2.

[0037] When the protective cover 41 falls back to the initial position and covers the grinding wheel 2, in order to prevent the protective cover 41 from directly contacting the grinding wheel 2 and causing damage to the grinding wheel 2, it is necessary to control the rotation angle of the protective cover 41. Therefore, the bracket 1 includes a baffle 11, which is installed on the side of the bracket 1. At the same time, the protective cover 41 is also provided with a baffle on the side. When the protective cover 41 rotates toward the operating port, the baffle abuts against the baffle 11. At this time, the baffle 11 restricts the baffle from continuing to rotate, thereby restricting the protective cover 41 from further rotating toward the operating port. In this way, the protective cover 41 will not directly contact the grinding wheel 2 while covering the operating port and the grinding wheel 2, thereby preventing the grinding wheel 2 from being damaged.

[0038] In order to avoid direct contact between the operator and the grinding machine, the bracket 1 also includes a guardrail 12, which is installed at the front end of the bracket 1. When the operator uses the grinding machine to grind the tool, he needs to stand in front of the grinding machine. At this time, the guardrail 12 of the grinding machine is closer to the operator. The guardrail 12 can further prevent the operator from directly contacting the grinding machine. Therefore, the guardrail 12 can remind the operator to keep a certain safe distance from the grinding machine to ensure that the operation of the grinding machine will not cause harm to the operator. In order to further improve the blocking effect of the guardrail 12, certain warning signs can also be set on the guardrail 12 to further warn the operator to keep a safe distance from the grinding machine.

[0039] Therefore, the grinding machine in the present application adopts the grinding wheel anti-splash device described above to prevent the grinding wheel 2 from blocking the splashing objects from flying toward the human body when grinding the tool, thereby preventing the splashing objects from causing harm to the human body, thereby ensuring the safety of the grinding process and maintaining the orderly progress of the grinding process.

[0040] To sum up, when it is necessary to use the grinding wheel anti-splash device and the grinding machine in this embodiment to grind the tool, first turn the adjusting knob 42 so that the protective cover 41 can rotate, and let the protective cover 41 rotate in the direction away from the operation port. After rotating to a certain angle, turn the adjusting knob 42 again to lock the protective cover 41 on the bracket 1 to limit the rotation of the protective cover 41, and then turn on the motor that drives the grinding wheel 2 to rotate, so that the motor controls the grinding wheel 2 to start rotating and start grinding the tool; after grinding is completed, turn off the motor that drives the grinding wheel 2 to rotate, so that the grinding wheel 2 stops rotating, and then turn the adjusting knob 42 again to contact the lock of the protective cover 41 and rotate the protective cover 41 to its original position, and finally turn the adjusting knob 42 again to lock the protective cover 41 on the bracket 1 again.
