[0002] When a punch press is in operation, it usually needs to be filled with lubricating oil. The oil drum is generally hung vertically on the outer side of the equipment and has a limit oil filling position mark. The oil drum is fed into the punch press machine through the bottom conveyor pipe. The limit oil filling position mark of the oil drum usually needs to be visually judged by the operator from time to time, which is inconvenient and labor-intensive. When the oil filling position is reached or lower than the limit oil filling position mark, and the operator does not detect the leakage and the oil is exhausted in time, the machine is still running normally, which can easily cause damage to the machine and produce defective products.

[0003] Therefore, it is essential to design an automatic oil level detection device. Utility Model Content

The spring-loaded rocker arm has a second terminal block at its first end and a moving contact at its second end. Terminal blocks one and two are electrically connected to the alarm. The moving and stationary contacts are correspondingly arranged. When the moving contact contacts the stationary contact, a current loop is formed, and the alarm is in a non-alarm state. When the moving and stationary contacts separate, the current loop is broken, and the alarm is activated. The first end of the spring-loaded rocker arm is connected to the main support component... The first end of the component is fixedly connected, and the second end of the elastic rocker arm is in contact with or separate from the second end of the main bearing component. The oil drum is fixed to the second end of the elastic rocker arm, and the oil drum is equipped with a limit filling position mark. When the oil level in the oil drum is higher than the limit filling position mark, the second end of the elastic rocker arm is in contact with the second end of the main bearing component. At this time, the moving contact and the stationary contact form a current circuit, and the alarm is in a non-alarm state. When the oil level in the oil drum is equal to or lower than the limit filling position mark, the second end of the elastic rocker arm is separated from the second end of the main bearing component. At this time, the moving contact and the stationary contact separate, the current circuit is broken, and the alarm is in an alarm state.

[0007] According to the above scheme, the main bearing component includes a housing, which has an inner cavity and a groove. The first end of the elastic rocker arm has a straight rod section, and the second end of the elastic rocker arm has a bent section. The straight rod section is fixed in the inner cavity by a fixing component, and the bent section is movably located in the groove. The oil drum is fixed to the bent section in the groove by a hanging rope. An elastic adjustment component is provided between the straight rod section and the housing.

[0008] According to the above scheme, the housing is provided with a through hole, and the elastic adjustment component includes a screw, a nut, a washer and a spring. The lower end of the screw passes through the nut, the washer, the spring and the through hole in sequence and is locked with the straight rod section. The nut is threadedly connected to the screw, and the two ends of the spring abut against the washer and the outer wall of the housing respectively.

[0009] According to the above scheme, a through hole is formed at the lower end of the screw, and the straight rod section is inserted into the through hole.

[0010] According to the above scheme, the housing is provided with a through hole 2. The fastener 1 includes a screw 2, a nut 2 and a washer 2. The lower end of the screw 2 passes through the nut 2, the washer 2 and the through hole 2 in sequence and is locked with the straight rod section. The nut 2 is threadedly connected to the screw 2. The two ends of the washer 2 abut against the nut 2 and the outer wall of the housing 1.

[0011] According to the above scheme, the lower end of the screw has a through hole, and the straight rod section passes through the through hole.

[0012] According to the above scheme, the oil drum includes a drum body, an oil inlet is formed at the upper end of the drum body, an oil delivery pipe is connected to the lower end of the drum body, and the limit refueling position mark is located near the oil delivery pipe.

[0013] According to the above scheme, it also includes a second fixing component, and the main load-bearing component is fixed to the outer part of the equipment mechanism through the second fixing component.

[0014] According to the above scheme, the second fixing component includes a second housing, a slot is formed inside the second housing, the slot is positioned with the main bearing component, and mounting plates are formed on both sides of the second housing, with mounting holes formed on the mounting plates.

[0015] According to the above scheme, an insulating sleeve is fitted on the spring rocker arm between the second terminal and the moving contact.

[0016] The beneficial effects of this utility model are:

[0017] This invention is designed so that when the oil drum is full, the oil level is above the limit filling mark. The weight of the drum presses down, causing the second end of the spring-loaded lever to descend. The moving contact and the stationary contact form a current loop, and the alarm is off. At this time, the spring-loaded lever is in a compressed, energy-storing state. When the oil level in the drum reaches or exceeds the limit filling mark, the weight of the drum decreases, and the spring-loaded lever releases energy and rebounds. The second end of the spring-loaded lever separates from the second end of the main support component, and the moving contact and the stationary contact break the current loop. The alarm is on, prompting manual refilling. After refilling, the weight of the drum causes the second end of the spring-loaded lever to descend again, and the moving contact and the stationary contact form a current loop. The alarm is off. The automatic opening and closing of the current loop turns the alarm on and off, prompting manual refilling. This design is convenient, saves labor, and does not cause damage to the machine.

[0027] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 7As shown, the automatic oil level detection device of this utility model includes a main support component 1, a spring-loaded rocker arm 2, an oil tank 3, and an alarm. The main support component 1 has a first terminal block 16 at its first end and a stationary contact 17 at its second end. The spring-loaded rocker arm 2 has a second terminal block 22 at its first end and a moving contact 24 at its second end. The first terminal block 16 and the second terminal block 22 are electrically connected to the alarm. The moving contact 24 and the stationary contact 17 are correspondingly arranged. When the moving contact 24 contacts the stationary contact 17, a current loop is formed, and the alarm is in a non-alarm state. When the moving contact 24 separates from the stationary contact 17, the current loop is broken, and the alarm is in an alarm state. The spring-loaded rocker arm... 2. The first end of the spring lever 2 is fixedly connected to the first end of the main support component 1. The second end of the spring lever 2 is in contact with or separate from the second end of the main support component 1. The oil drum 3 is fixed to the second end of the spring lever 2. The oil drum 3 is equipped with a limit filling position mark 35. When the oil level in the oil drum 3 is higher than the limit filling position mark 35, the second end of the spring lever 2 is in contact with the second end of the main support component 1. At this time, the moving contact 24 and the stationary contact 17 are in contact to form a current circuit, and the alarm is in a non-alarm state. When the oil level in the oil drum 3 is equal to or lower than the limit filling position mark 35, the second end of the spring lever 2 is separated from the second end of the main support component 1. At this time, the moving contact 24 and the stationary contact 17 are separated to form a current circuit break, and the alarm is in an alarm state. With this setup, when oil drum 3 is full, the oil level in oil drum 3 is higher than the limit refill position mark 35. The overall weight of oil drum 3 presses down, causing the second end of the spring lever 2 to descend. The moving contact 24 contacts the stationary contact 17, forming a current circuit, and the alarm is in a non-alarm state. At this time, the spring lever 2 is in a compressed energy storage state. When the oil level in oil drum 3 reaches or exceeds the limit area mark 35, the overall weight of oil drum 3 decreases, and the spring lever 2 is in a released energy state, causing it to rebound. The second end of the spring lever 2 separates from the second end of the main support component 1, and the moving contact 24 separates from the stationary contact 17, breaking the current circuit. The alarm is in an alarm state, prompting manual refilling. After refilling, oil drum 3, relying on its weight, again causes the second end of the spring lever 2 to descend, and the moving contact 24 contacts the stationary contact 17, forming a current circuit. The alarm is in a non-alarm state. The automatic closing and opening of the current circuit realizes the alarm's on / off state and prompts manual refilling. This method is convenient to use, saves labor, and does not cause damage to the machine.
