[0029] The main unit 100 includes an electrical box 101, an oil mist lubrication box 104 is fixedly connected to the side wall of the electrical box 101, an oil cup 103 is fixedly connected to the upper end of the oil mist lubrication box 104, and a machine tool spindle shaft 102 is fixedly installed at the lower end of the electrical box 101;

[0030] The monitoring alarm component 200 includes two support plates 201, both of which are fixedly connected to the inner wall of the oil cup 103, a floating plate 202 is slidably arranged between the two support plates 201, a floating ball 205 is fixedly installed on the upper end of the floating plate 202, a support frame 206 is fixedly connected to the upper ends of the two support plates 201, two connecting rods 207 are symmetrically fixedly connected between the support frames 206, the opposite ends of the two connecting rods 207 are fixedly connected to a pipe sleeve 208, the lower end of the pipe sleeve 208 is fixedly connected to an arc cover 209, a push rod 210 is slidably inserted in the pipe sleeve 208, two cross plates 213 are symmetrically fixedly connected to the side wall of the push rod 210, each of the cross plates 213 is fixedly connected to a reset spring 214, the upper end of the push rod 210 is fixedly connected to a pressure plate 211, and the lower end of the support frame 206 is fixedly installed with a trigger 212.

[0031] As the lubricating oil is consumed and the liquid level reaches the critical line, the buoyancy of the lubricating oil on the float plate 202 and the float ball 205 decreases, and the push rod 210 is pushed downward by the elastic force of the return spring 214, so that the pressure plate 211 is separated from the trigger 212. At this time, the trigger 212 detects the downward movement of the pressure plate 211 and transmits an electrical signal to the touch screen, which reminds the staff through the touch screen, so as to timely discover the depletion of the lubricating oil and avoid negative impact on the lubrication effect, thereby improving the performance and stability of the machine tool.

[0032] Among them, grooves are opened on the opposite sides of the two support plates 201, and a sliding rod 203 is fixedly connected in each groove. Two limit blocks 204 are symmetrically fixedly connected on both sides of the floating plate 202. Each limit block 204 is slidably sleeved on the sliding rod 203, and the floating plate 202 is limited by the limit blocks 204 and the sliding rod 203.

[0033] The lower end of the push rod 210 passes through the arc cover 209 and abuts against the upper end of the float 205 . The upper ends of the two reset springs 214 are fixedly connected to the lower end of the support frame 206 . The reset springs 214 can reset the push rod 210 .

[0034] A connecting pipe 105 is fixedly connected to the side wall of the oil mist lubrication box 104 , and the other end of the connecting pipe 105 is connected to the inside of the machine tool spindle shaft 102 . The lubricating oil enters the inside of the machine tool spindle shaft 102 through the connecting pipe 105 to lubricate it.

[0035] A touch screen is fixedly connected to the side wall of the electrical box 101 , and the trigger 212 is connected to the touch screen via an electrical signal, so that commands can be issued conveniently via the touch screen.

[0036] The upper end of the oil cup 103 is fixedly connected with an oil inlet pipe, and the upper end of the oil inlet pipe is meshingly connected with a sealing cover, and lubricating oil is added through the oil inlet pipe.

[0037] Working principle: When in use, the lubricating oil enters the inside of the machine tool spindle shaft body 102 through the connecting pipe 105 to lubricate it. At this time, the lubricating oil in the oil cup 103 generates a large buoyancy on the floating plate 202 and the floating ball 205, and the buoyancy is greater than the elastic force of the reset spring 214, and the push rod 210 is pushed upward through the floating ball 205, and the push rod 210 pushes the pressure plate 211 to move upward and against the trigger 212, which proves that the oil is sufficient; as the lubricating oil is consumed, when the liquid level reaches the critical line, the lubricating oil exerts a large buoyancy on the floating plate 202 and the floating ball 205. The buoyancy of the ball 205 decreases, and the push rod 210 is pushed downward by the elastic force of the return spring 214, so that the pressure plate 211 is separated from the trigger 212. At this time, the trigger 212 detects that the pressure plate 211 moves downward and transmits an electrical signal to the touch screen, which reminds the staff through the touch screen, so as to timely discover the depletion of lubricating oil and avoid negative impact on the lubrication effect, thereby improving the performance and stability of the machine tool. The contents not described in detail in this description belong to the existing technology known to professional and technical personnel in this field.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
