Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.

Particular embodiments of the present application provide a grinder splash guard, as shown in fig. 1 and 2, comprising: the protective cover comprises a protective cover body 1, wherein a through hole for a grinding machine main shaft to pass through is formed in the protective cover body 1, and the grinding machine main shaft penetrates through the through hole, so that the protective cover body 1 is sleeved on the periphery of the grinding machine main shaft. The shield body 1 is connected with the grinder frame in a lifting way through a lifting device 2. The first end of the lifting device 2 is connected with the grinder frame, the other end of the lifting device is connected with the shield body 1, and the lifting device 2 controls the shield body 1 to be close to and far away from the grinder frame, so that the shield body 1 is lifted. The grinding disc for grinding is arranged at the bottom end of the main shaft of the grinding machine, and the top end of the main shaft of the grinding machine is connected with the motor.

In actual use, a workpiece is placed below the grinding disc, and then the main shaft of the grinding machine is lowered, so that the grinding disc reaches the height capable of grinding the workpiece. Because the grinding disc descends, the distance between the grinding disc and the shield body 1 is too large, and the grinding disc and the workpiece cannot be well protected. At this moment, the lifting device 2 controls the shield body 1 to descend until the shield body descends to a proper position, and the shield body 1 can better shield the grinding disc at the moment. The drive motor drives the grinding disc to rotate to process a workpiece, grinding fluid is ejected to the shield body 1 after being taken out by the grinding disc, the grinding fluid is effectively prevented from splashing, and meanwhile, the shield body 1 can also prevent the workpiece from being loosened and thrown out to cause injury to workers.

After grinding, the lifting device 2 controls the shield body 1 to ascend, and after an ascending space is reserved for the main shaft of the grinding machine, the main shaft of the grinding machine drives the grinding disc to ascend to be far away from the workpiece, and then the workpiece can be taken down.

Wherein, the lifting device 2 can be a cylinder. During installation, the cylinder body of the air cylinder is connected to the frame of the grinding machine, the piston rod of the air cylinder is connected to the top surface of the shield body 1, and the piston rod is driven to move up and down in the cylinder body, so that the shield body 1 can be driven to move up and down.

In actual use, a workpiece is placed below the grinding disc, and then the main shaft of the grinding machine is lowered, so that the grinding disc reaches the height capable of grinding the workpiece. At this moment, the shield body 1 is controlled to descend by the driving cylinder until the shield body descends to a proper position, and the shield body 1 can better shield the grinding disc at the moment. The drive motor drives the grinding disc to rotate to process a workpiece, grinding fluid is ejected to the shield body 1 after being taken out by the grinding disc, the grinding fluid is effectively prevented from splashing, and meanwhile, the shield body 1 can also prevent the workpiece from being loosened and thrown out to cause injury to workers.

As an alternative, in the specific embodiment of the present application, as shown in fig. 1 and 2, a sensor is provided on the shield body 1 for detecting the distance between the shield body 1 and the bottom end of the main shaft of the grinding mill, and the sensor is connected to the lifting device 2 through a control module, wherein the lifting device 2 may be a servo cylinder. The cylinder body of the servo cylinder is connected on the frame of the grinder, and the piston rod is connected on the top surface of the shield body 1

When the operation guard shield body 1 descends, the servo cylinder is controlled to work through the control module to drive the guard shield body 1 to move downwards, the distance between the guard shield body 1 and the bottom end of the main shaft of the grinding machine is detected in real time, when the distance is reduced to a preset value, the sensor sends a signal to the control module, the control module controls the servo cylinder to stop working, the guard shield body 1 does not descend any more, and the grinding operation can be safely carried out at the moment.

The control module can be a PLC (programmable logic controller).

As an alternative embodiment, in the specific embodiment of the present application, as shown in fig. 1 and 2, a plurality of lifting devices 2 are provided, one ends of the plurality of lifting devices 2 are all fixedly provided on the grinder frame, and the other ends of the plurality of lifting devices 2 are all provided on the top surface of the shield body 1. So set up, a plurality of elevating gear 2 support jointly and drive shield body 1 for shield body 1 is more stable at the lift in-process.

Wherein elevating gear 2 can evenly distributed on the top surface of shield body 1 for shield body 1 atress is more stable.

As an alternative embodiment, in the specific embodiment of the present application, as shown in fig. 1 and 2, a flap 3 is provided downward at the rim of the shield body 1. So set up, the cover is established the scope and is bigger, and is better to the protective effect of grinding department.
