The utility model provides an automatic oil supplementing machine of hydraulic tappet, a serial communication port, which comprises a frame, a controller, a driving device, the push rod, the oil tank, controller and drive arrangement are installed on the frame, drive arrangement and controller are connected, the below at drive arrangement is installed to the oil tank, thereby drive arrangement can drive the plunger motion of the vertical up-and-down motion promotion hydraulic tappet of push rod, pressure sensor is installed to the one end that drive arrangement was kept away from to the push rod, pressure sensor is connected with the input of controller, install the fixing device of fixed hydraulic tappet in the oil tank, the number of times of reciprocating motion about the push rod can be calculated to the counter, the time that pressure sensor from detecting pressure reaches the settlement pressure can be recorded to the time of time-recorder and controller's input connection.
When the driving device drives the push rod to move downwards, the push rod is inserted into the hydraulic tappet to push the plunger to move downwards, air in the high-pressure oil cavity is compressed and discharged from a gap between the plunger and the cylinder, when the pressure sensor detects that the pressure between the push rod and the plunger reaches a set pressure value, the driving device drives the push rod to move upwards, the plunger moves upwards under the action of the reset spring, the high-pressure oil cavity is used for discharging air, when the plunger moves upwards, suction force is generated in the high-pressure oil cavity, oil in the oil tank is sucked into the high-pressure oil cavity, the high-pressure oil cavity completes one-time oil supplementing, then the push rod continues to reciprocate, the high-pressure oil cavity realizes multiple oil supplementing until the time from the detection of the pressure of the push rod to the detection of the pressure reaching the set value is not more than the set time in one-time in the process of pushing the counter, and the number of times of reciprocation of the push rod detected by the counter is not less than the set minimum number of times. When the high-pressure oil cavity is filled with oil, the push rod cannot push the plunger to move again, the pressure detected by the pressure sensor instantaneously reaches a set pressure value, and the time recorded by the timer is close to zero at the moment, so that whether the hydraulic tappet is filled with oil can be judged by using the time of the timer. In order to avoid the situation that the high-pressure oil cavity is not full due to the fact that the pressure sensor detects a set pressure value in advance due to position errors of the hydraulic tappet and the push rod, the counter is used for assisting in judging whether the high-pressure oil cavity of the hydraulic tappet is full or not, and the qualification rate of the hydraulic tappet is improved. The counter can utilize the light sensor technology, and the push rod shields the light that the light sensor sent twice every time, and push rod up-and-down motion is once promptly, counts once. The invention can realize automatic oil supplementing and detection, has high efficiency and high qualification rate, and can meet the requirement of industrial production of hydraulic tappet.

Furthermore, an adjusting nut is arranged on the piston, and the height distance of the push rod relative to the fixing device can be adjusted by rotating the adjusting nut.
Further, a guide rail for adjusting the position of the fixing device is arranged in the oil tank.
Further, the fixing device comprises a sleeve and a chassis, the inner diameter of the sleeve is matched with the outer diameter of the hydraulic tappet, and the chassis can move on the guide rail.
The oil supplementing method of the automatic hydraulic tappet oil supplementing machine is characterized by comprising the following steps of:
Step one: the hydraulic tappet is fixed in the oil tank by a fixing device, and the liquid level in the oil tank is higher than that of the hydraulic tappet;
Step two: opening a starting button, wherein the push rod moves downwards at a constant speed under the drive of a driving device, pushing a plunger of the hydraulic tappet to move downwards, detecting pressure by a pressure sensor, enabling a pressure value detected by the pressure sensor to reach a set value, driving the push rod to move upwards and downwards rapidly by the driving device, and counting by a counter once; the timer records the time from the detection of the pressure by the pressure sensor to the time when the pressure reaches the set pressure;
Step three: when the time detected by the timer is not more than 0.1 second and the number of times detected by the counter is not less than 20, the hydraulic tappet is completed in oil supplementing, and the controller controls the driving device to stop moving.
In summary, the beneficial effects of the invention are as follows:
1. the oil supplementing machine can automatically complete oil supplementing and detection, is high in efficiency, is simple in structure and is easy to generate and manufacture;
2. by using the method for supplementing the oil to the hydraulic tappet, the qualification rate is up to 99.5%, and compared with the qualification rate of 85% of manual oil supplementing, the qualification rate of the hydraulic tappet for one-time oil supplementing is greatly improved;
3. the extension length of the push rod is adjustable and replaceable, so that the push rod is convenient for being applicable to different parts.
