[0033] In the embodiments of this utility model, please refer to Figures 1 to 3 The protective device 5 includes a slide 501, with baffles 503 fixedly connected to both ends of the slide 501. The baffles 503 are fixedly connected to the worktable 2. A sliding column 502 is fixedly connected to the side of the two baffles 503 that is close to each other. Two sliders 505 are slidably connected to the arc surface of the sliding column 502. A protective cover 506 is fixedly connected to the upper surface of each slider 505. Two first springs 504 are sleeved on the arc surface of the sliding column 502. Each of the two first springs 504 is respectively connected to the slider 505. The protective cover 506 is fixedly connected to the baffle 503. A rectangular hole 507 is provided on one side of the protective cover 506, and an acrylic plate 508 is fixedly connected to the inner wall of the rectangular hole 507. A liquid injection hole 509 is provided on the upper surface of the protective cover 506. A support plate 511 is fixedly connected to one side of the protective cover 506, and a pin 512 is slidably connected to one side of the support plate 511, completely penetrating the support plate 511. A row of insertion holes 514 is provided on the upper surface of the worktable 2 corresponding to the position of the pin 512. This design achieves the effect that when coolant is applied to the tap from the reservoir 8 through the liquid injection hole 509 during the tap grinding process, splashing occurs. By placing the two protective covers 506 close to each other, splashing can prevent injury to personnel. A handle 510 is fixedly connected to the upper surface of the protective cover 506, and the handle 510 has a U-shaped cross-section. This design achieves the effect of making the operation simpler and more convenient by pulling the two protective covers 506 together using the handle 510.

[0034] In the embodiments of this utility model, please refer to Figures 4 to 6The mobile device 6 includes a rectangular groove 601, a rectangular block 602 slidably connected to the inner wall of the rectangular groove 601, a support plate 603 fixedly connected to the upper surface of the rectangular block 602, a circular groove 604 opened on the side of the support plate 603 near the protective cover 506, a turntable 605 rotatably connected to the inner wall of the circular groove 604, a fixing ring 612 fixedly connected to the other side of the support plate 603, a second motor 611 fixedly connected to the inner wall of the fixing ring 612, the second motor 611 fixedly connected to the support plate 603, the output end of the second motor 611 fixedly connected to the turntable 605, a fixing tube 606 fixedly connected to one side of the turntable 605, a screw 609 threadedly connected to the arc surface of the fixing tube 606, a lead screw 613 rotatably connected to the inner wall of the rectangular groove 601, the lead screw 613 threadedly connected to the rectangular block 602, a nut 614 fixedly connected to one end of the lead screw 613, and three grips 615 fixedly connected to the side of the nut 614. The system achieves the effect of fixing the tap via the fixing tube 606 and the screw 609, moving the tap to the grinding assembly 7, and allowing grinding of different parts of the tap by rotating the turntable 605. A knob 607 is fixedly connected to one end of the screw 609, and the knob 607 has four arc-shaped grooves 608 on its arc surface. This allows for easier application of force when rotating the screw 609, thanks to the arc-shaped grooves 608 on the knob 607. An anti-wear pad 610, a circular pad, is fixedly connected to the end of the screw 609 away from the knob 607. This reduces wear between the screw 609 and the tap when the screw 609 is used to press and fix the tap.

[0035] The working principle of the anti-splash cover for tap grinding coolant provided by this utility model is as follows: Before grinding the tap, the coolant in the storage tank 8 needs to be stored to ensure that there is enough coolant during the grinding process. Then the protective device 5 can be operated. First, the pin 512 inserted into the insertion hole 514 needs to be pulled upward. During the upward pulling of the pin 512, the second spring 513 extends due to the pulling force of the pin 512, generating an elastic force opposite to the direction of movement of the pin 512. When the pin 512 is pulled upward from the insertion hole 514, the pin 512 is attracted to the magnetic plate 515, so that the pin 512 is temporarily stored and will not slide downward during the movement of the protective cover 506. After storing the pin 512, the two protective covers 506 can be pulled closer together using the handle 510 on the protective cover 506. During this movement, the protective covers 506 slide on the sliding post 502 via the connected slider 505. Simultaneously, the first spring 504 is extended by the slider 505, generating a spring force opposite to the direction of movement of the protective covers 506. Once the two protective covers 506 are pulled to the appropriate position, the pin 512 can be removed from the magnetic plate 515. At the same time as removing the pin 512, the pin 512... Due to the elastic force generated by the second spring 513, pin 512 will automatically slide downward along the support plate 511 and insert into the insertion hole 514 on the worktable 2 corresponding to the position of pin 512, thereby fixing the two protective covers 506. During grinding, the progress of the grinding work can be observed through the acrylic plate 508 in the rectangular hole 507 on the side of the protective cover 506. Coolant can also be dripped onto the tap through the liquid injection hole 509 on the top of the protective cover 506. When the grinding work is completed, pin 512 can be pulled out again. At this time, the protective cover 506 will automatically slide back to its original position in the direction away from each other due to the elastic force of the first spring 504.

[0036] After bringing the two protective covers 506 together and enclosing the grinding assembly 7 inside the protective covers 506, the position of the tap can be fixed using the moving device 6. The specific operating steps are as follows: Before grinding the tap, the tap must first be inserted into the fixing tube 606. After the tap is placed in the fixing tube 606, the screw 609 can be rotated using the knob 607. During the rotation of the screw 609, the screw 609 moves towards the inside of the fixing tube 606 through the internal thread. As the screw 609 moves, the anti-wear pad 610 connected to it also moves in the same direction with the screw 609. When the anti-wear pad 610 comes into contact with the tap under the action of the screw 609, the screw 609 presses and fixes the tap inside the fixing tube 606. Once the tap is fixed, the lead screw 613 can be rotated using the three levers 615 on the side of the nut 614. As the lead screw 613 rotates, it slides within the rectangular groove 601 via the threads in the rectangular block 602. Simultaneously, the rectangular block 602 moves the upper support plate 603 towards the grinding assembly 7, thus moving the tap in the same direction. Once the tap is positioned at the grinding assembly 7, the first motor 9 can be controlled to rotate the grinding assembly 7 to begin grinding the tap. When different positions of the tap need to be ground, the output end of the second motor 611 can be controlled to rotate. When the output end of the second motor 611 starts to rotate, it will drive the turntable 605 to rotate. While the turntable 605 rotates, it drives the tap to rotate, thereby changing the contact position between the tap and the grinding assembly 7, so as to achieve grinding of different positions of the tap. The arc groove 608 on the arc surface of the knob 607 makes it easier to apply force when the screw 609 is rotated. The anti-wear pad 610 located at the lower end of the screw 609 can reduce the degree of wear between the screw 609 and the tap when they are in contact.
