DETAILED DESCRIPTION

[0020] The utility model provides a cooling and lubricating device for an electric grinding output shaft, such as Figure 1-4 As shown, it includes a first section 11, a second section 13, a liquid storage tank 15, a pressurizing assembly and a protrusion 26, and the second section 13 is fixedly connected to the first section 11, as shown in FIG. Figure 1-2As shown, a threaded portion 12 is provided on the outer surface of the first section 11, a material guide groove 18 is provided in the second section 13, a material discharge groove 19 is provided in the second section 13, and the material discharge groove 19 is located on the side of the material guide groove 18 away from the first section 11. The liquid storage tank 15 is installed on the grinder or the handle through a mounting plate 16, and a mounting hole 17 is provided in the mounting plate 16. The mounting hole 17 is used for fixing with screws, a liquid storage cavity 20 is provided in the liquid storage tank 15, and a spray hole 22 is provided in the liquid storage tank 15. The spray hole 22 is connected to the liquid storage cavity 20. A pressurizing component is provided in the liquid storage cavity 20, and the pressurizing component is used to spray the cooling lubricant through the spray hole 22. The protrusion 26 is fixedly provided on the outer cylindrical surface of the first section 11.

[0021] A third section 14 is fixedly disposed at one end of the first section 11 away from the second section 13 , and a through hole is formed in the third section 14 .

[0022] A liquid inlet pipe 21 connected to the liquid storage chamber 20 is fixedly provided in the liquid storage box 15 . A valve is provided in the liquid inlet pipe 21 . The liquid inlet pipe 21 is connected to the cooling lubricant bin through the valve and replenishes the cooling lubricant in the liquid storage chamber 20 .

[0023] like Figure 3-4 As shown, the pressurizing assembly includes a push plate 23, a push rod 24 and a push block 25. The push rod 24 is slidably disposed in the liquid storage tank 15, and the push plate 23 is slidably disposed in the liquid storage chamber 20. One end of the push rod 24 is connected to the push plate 23, and the other end of the push rod 24 extends to the outside of the liquid storage tank 15 and is fixedly connected to the push block 25. The position of the push block 25 corresponds to the protrusion 26.

[0024] A rubber sealing ring is provided on the contact surface between the push plate 23 and the inner wall of the liquid storage chamber 20 .

[0025] First, the liquid storage tank 15 is installed on the grinder or the handle through the mounting plate 16, and the motor drives the first section 11 and the second section 13 to rotate relative to the liquid storage tank 15. When the workpiece is ground, the grinding waste enters the discharge trough 19 through the guide groove 18, and then the grinding waste is discharged out of the grinder through the air caused by the rotation of the grinder itself. When the first section 11 drives the protrusion 26 to rotate relative to the liquid storage tank 15, the protrusion 26 is abutted against the push block 25 through the arc surface, and the push block 25 squeezes the push plate 23 located in the liquid storage chamber 20 through the push rod 24, so that the cooling lubricant is sprayed out through the cooling lubricant, and the cooling lubricant covers the output shaft and the workpiece for cooling and lubrication. When the cooling lubricant pressure in the liquid storage chamber 20 is not enough to spray out, the liquid inlet pipe 21 replenishes the cooling lubricant in the liquid storage chamber 20. At this time, the pressure in the liquid storage chamber 20 increases, thereby causing the push plate 23 to slide in the opposite direction and the push block 25 to be located in the initial position.
