Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic servo motor filling equipment, and more particularly to an oil leakage detection and filling device for a hydraulic servo motor. Background Art

[0002] A hydraulic servo motor is a device that uses hydraulic technology to control motion. It mainly controls the rotation and output torque of the motor through the pressure and flow of hydraulic oil, achieving high-precision and high-response motion control. Compared with electric motors, hydraulic servo motors can provide greater power output under the same volume and are widely used in industrial automation, robotics, aerospace and other fields.

[0003] According to the drive form, hydraulic servo motors are mainly divided into axial piston motors, radial piston motors, gear motors and vane motors. For piston-driven motors, long-term work movement is affected by factors such as pressure and friction, which can easily cause aging and cracking of the inner wall of the piston cavity and loosening of the connectors, leading to oil leakage in the motor. Therefore, it is particularly important to detect motor leakage during operation.

[0004] At present, the main form of motor leakage detection is oil pressure detection, which includes oil pressure detection gauges independently installed on the oil filling pipe and the oil outlet pipe, and the leakage is determined by the values ​​displayed on the gauge body. It also includes oil pressure / flow rate sensing equipment installed in the oil filling pipe and the oil outlet pipe, and the leakage is determined by the values ​​displayed by the sensing equipment on the control equipment. The oil meter or sensor detection presentation method is relatively limited, and it is necessary to manually collect oil meter data or make judgments based on the data displayed by the sensing equipment on the control equipment. At the same time, the degree of oil leakage requires the calculation of pressure difference. Moreover, the data collection requires people to visit the equipment in person, which makes the judgment process cumbersome and affects the judgment speed and efficiency.

[0005] Therefore, in order to solve the above technical problems, the present application proposes an oil leakage detection and filling device for a hydraulic servo motor. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention aims to provide an oil leakage detection and filling device for a hydraulic servo motor.

The two groups of detection components are provided with a conductive rod-type component connected in parallel with the negative battery connection line through a line. Two warning areas consisting of multiple groups of lamp bodies are provided on the end faces corresponding to the two groups of detection components on the outside of the detection box. Two groups of branching devices are provided on the end faces corresponding to the two groups of detection components inside the detection box, which are connected to the negative terminal of the multiple lamp bodies on the two warning areas through lines and are electrically connected to the two groups of conductive rod-type components through contact. The positive terminal of the multiple lamp bodies on the two warning areas is connected in parallel to the positive battery connection line.

[0008] Preferably, the multiple groups of lamps on the two warning areas are arranged horizontally and are the same in number; the multiple groups of lamps in each of the two warning areas are different in color, and the lamps of different colors in the two warning areas are distributed in a mirror image form.

[0009] Preferably, the detection component includes an elastic member, a limiting member and a detection member; wherein, the elastic member includes a fixed disk, a spring and a movable disk, the fixed disk is connected to the inner wall of the detection box, and the spring is arranged between the fixed disk 901 and the movable disk; the limiting member includes two groups of limiting slides arranged at the top and bottom of the movable disk, and engaged with the strip-shaped slide grooves arranged at the top and bottom of the detection box; the detection member includes a spherical seat and a support rod connected between the spherical seat and the movable disk.

[0010] Preferably, the oil filling pipe and the oil outlet pipe are symmetrically provided with spherical seats that can be partially embedded in the connecting openings inside the pipe body, and the connecting openings are provided with sealing gaskets.

[0011] Preferably, the conductive rod assembly includes a hollow connecting seat arranged at the side end of the movable disk and a metal rod extending from the inner center of the connecting seat to the branching device, and a line connection end is provided on the part of the metal rod embedded in the connecting seat.

[0013] Preferably, the number of the disc seats and metal sheets corresponds to the number of lamp bodies in the warning area, and the plurality of metal sheets correspond to the positions of the outer ends of the metal rods and are in contact with each other.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention detects motor oil leakage mainly based on the influence of different forces generated during the oil circulation process on the detection component during oil filling and oil discharge. Different forces during oil filling and oil discharge drive the detection component to move to different positions. At different positions, the power connection position affects the opening and closing of the corresponding lamp bodies on the oil filling and oil discharge warning areas. By comparing the opening positions and spacing of the lamp bodies on the oil filling and oil discharge warning areas, the oil leakage inside the motor and the degree of oil leakage can be directly determined.

Under the coordination of the force generated by the oil at different speed regulation levels and the adaptability of the spring, the speed regulation level of the hydraulic pump can correspond to the lamps on the oil filling warning area. In this way, the current oil filling status of the hydraulic pump can be directly judged more intuitively. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] like Figure 1-11 As shown, the present invention provides an oil leakage detection and filling device for a hydraulic servo motor, comprising an oil tank consisting of a cooling chamber 1 and an oil filling chamber 2, a control console 3 and a hydraulic pump 4 arranged on the top of the oil tank, and a detection box 5 arranged next to the control console 3 for oil circulation and oil leakage detection of the hydraulic servo motor;

[0042] The detection box 5 mainly utilizes the physical characteristics of the oil filling and oil return process, and uses the pressure difference when the hydraulic servo motor is leaking, in conjunction with the opening and closing state of the corresponding lamp body 503 and the symmetry analysis of the opening and closing of the lamp body 503 during oil filling and oil return, thereby achieving the detection of oil leakage and the extent of oil leakage in the hydraulic servo motor;

[0043] The structure of the above-mentioned detection box 5 is as follows: Figure 2 、 Figure 3 As shown, it specifically includes the following: a battery 6 is provided on one side, an oil filling pipe 7 and an oil outlet pipe 8 are provided inside, and a detection component 9 is provided on both sides of the oil filling pipe 7 and the oil outlet pipe 8 for detecting the force generated by the oil flow inside the oil filling pipe 7 and the oil outlet pipe 8, and can adaptively move according to the magnitude of the force;

[0044] Among them, combined Figure 1 、 Figure 2 and Figure 3 As shown, one end of the oil filling pipe 7 and the oil outlet pipe 8 are respectively connected to the oil pipe external interface b502 and the oil pipe external interface a501 provided on the detection box 5, and the other ends of the oil filling pipe 7 and the oil outlet pipe 8 are respectively connected to the oil outlet port of the hydraulic pump 4 and the cooling chamber 1. During the circulation of oil, the piston of the hydraulic servo motor is driven to move, thereby driving the hydraulic servo motor;

[0045] In order to achieve the oil leakage detection of hydraulic servo motor during the driving process of hydraulic servo motor, such as Figure 3 、 Figure 11 As shown, two sets of detection components 9 corresponding to the oil filling pipe 7 and the oil outlet pipe 8 are used. When oil leaks, the different oil pressures in the oil filling pipe 7 and the oil outlet pipe 8 cause different forces to be generated during the circulation process. Under different forces, the two sets of detection components 9 produce different effects, that is, when the positions are different, the two warning areas corresponding to the open lamp bodies 503 are in mirror image positions, so as to determine whether the hydraulic servo motor is leaking.

[0046] Further explanation, such as Figure 9 and Figure 10 As shown, the detection assembly 9 includes an elastic member, a limiting member and a detection member. The elastic member includes a fixed plate 901, a spring 902 and a movable plate 903. The fixed plate 901 is connected to the inner wall of the detection box 5. The spring 902 is arranged between the fixed plate 901 and the movable plate 903. The limiting member includes two groups of limiting slides 907 arranged at the top and bottom of the movable plate 903 and engaged with the strip-shaped slide grooves arranged at the top and bottom of the detection box 5. The detection member includes a spherical seat 906 and a support rod connected between the spherical seat 906 and the movable plate 903.

[0047] Specifically, the detection component 9 mainly determines the magnitude of the force generated by the oil during oil injection and oil return, which affects the movement of the spherical seat 906. The specific position of the spherical seat 906 is used to determine the magnitude of the force. The magnitude of the force determines the magnitude of the oil pressure during oil injection and oil return. When the oil pressure during oil return is lower than the oil pressure during oil injection, the positions of the two sets of spherical seats 906 will be different.

[0048] In order to enable the detection component 9 to detect the oil in the oil filling pipe 7 and the oil outlet pipe 8, Figure 3 、 Figure 4 and Figure 5 As shown, the oil filling pipe 7 and the oil outlet pipe 8 are symmetrically provided with spherical seats 906 that can be partially embedded in the connecting port 10 inside the pipe body, and a sealing gasket 11 is provided at the connecting port 10;

[0049] To further illustrate, the detection component 9 needs to meet two conditions for detecting the oil in the oil filling pipe 7 and the oil outlet pipe 8. First, it needs to ensure that the oil can flow normally in the oil filling pipe 7 and the oil outlet pipe 8, that is, the sealing is guaranteed; second, under the condition that the oil filling pipe 7 and the oil outlet pipe 8 ensure the sealing, the ball seat 906 can be displaced by the force of the oil.

[0050] Specifically, in order to ensure the normal circulation of oil, it is necessary to ensure that the ball seat 906 is partially embedded in the oil filling pipe 7 and the oil outlet pipe 8, for example, the embedded part of the ball seat 906 is 1 / 3 or 2 / 5 of the ball seat 906, and for the sealing protection of the oil filling pipe 7 and the oil outlet pipe 8, a soft sealing gasket 11 is used. The sealing gasket 11 can be an elastic gasket, such as a rubber gasket or a high-toughness membrane. That is to say, when the ball seat 906 is embedded, it will drive the sealing gasket 11 into the oil pipe together. The sealing gasket 11 will be fixed to the connecting port 10 by screws in conjunction with the fixing strip arranged according to the curved structure of the connecting port 10, so that the normal detection of the detection component 9 can be achieved while ensuring the normal circulation of oil in the oil pipe. The maximum position of the movement of the ball seat 906 of the detection component 9 is that the embedded end surface is flush with the connecting port 10;

[0051] In order to achieve the best presentation of the detection effect, such as Figure 2 and Figure 3 As shown, the displacement of the detection component 9 is connected to the power of different lamp bodies 503. By comparing the positions of the lamp bodies 503 on the two warning areas, the oil leakage detection and the degree of oil leakage detection can be achieved. Figure 1 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 8As shown, both detection components 9 are provided with a conductive rod-type component connected in parallel with the negative terminal connection line of the battery 6 via a circuit. Two warning areas consisting of multiple groups of lamp bodies 503 are provided on the end surfaces of the outside of the detection box 5 corresponding to the two detection components 9. Two groups of branching devices 12 are provided on the end surfaces of the inside of the detection box 5 corresponding to the two detection components 9, which are connected to the negative terminal of the multiple groups of lamp bodies 503 on the two warning areas via a circuit and are electrically connected to the two groups of conductive rod-type components through contact. The positive terminal of the multiple groups of lamp bodies 503 on the two warning areas is connected in parallel to the positive terminal connection line of the battery 6.

[0052] The positive and negative electrode interfaces of the battery 6 are equipped with electrode buses for connecting the positive and negative electrodes. The bus for the negative electrode of the battery 6 is connected to the conductive rod-type components on the two detection components 9 through two sets of parallel branches, while the bus for the positive electrode of the battery 6 is connected to the positive terminals of all the lamp bodies 503 in the two warning areas through multiple sets of parallel branches. The negative terminals of the multiple lamp bodies 503 are connected to the branching device 12 in an internal through-hole manner through the connected branches.

[0053] It should be noted that the lamp body 503 is connected to the positive terminal of the battery 6, and the conductive rod assembly is connected to the negative terminal of the battery 6. The electrode connection positions can also be swapped, depending on the position of the electrode interface of the battery 6.

[0054] The conductive rod assembly includes a hollow connection base 904 disposed at the side of the movable plate 903 and a metal rod 905 extending from the center of the connection base 904 to the branching device 12. The portion of the metal rod 905 embedded in the connection base 904 is provided with a line connection terminal.

[0055] Specifically, the metal rod 905 is the main component for power connection. The negative pole of the battery 6 directly passes through the detection box 5 and is connected to the connection base 904 and the metal rod 905. It is only necessary to ensure that the length of the wire can adapt to the movement of the detection component 9. The two sets of metal rods 905 are connected in parallel to the negative bus of the battery 6. The metal rod 905 can be a copper rod, an iron rod, a tungsten rod, etc. According to the conductivity, the copper rod is the best. For the embedded part of the metal rod 905 in the connection base 904, the branch line connected to the negative bus of the battery 6 is wound around it. When the detection component 9 moves and is subjected to force, the tightness and firmness of the connection between the wire and the metal rod 905 are ensured, and the transmission of power to the metal rod 905 is also ensured.

[0056] The above-mentioned branching device 12 mainly includes a branching seat 1201, a plurality of disk seats 1202 arranged at one end of the branching seat 1201 to fix the branching seat 1201 and provide an independent penetration for the line of each lamp body 503, and a plurality of metal sheets 1203 arranged at the other end of the branching seat 1201 and connected to the line passing through each lamp body 503. The metal sheet 1203 is provided with a rod-type connector embedded in the inside of the branching seat 1201. The negative electrode line of the lamp body 503 passing through the branching seat 1201 will be wound around the rod-type end of the branching seat 1201, so that the line can be tightly connected with the rod-type end of the metal sheet 1203, thereby ensuring the tightness and firmness of the connection between the line and the metal sheet 1203 when the detection component 9 moves and is subjected to force, and also ensuring the transmission of power to the metal sheet 1203.

[0057] At the same time, the number of disc bases 1202 and metal sheets 1203 corresponds to the number of lamp bodies 503 in the warning area, and the plurality of metal sheets 1203 correspond to the positions of the outer ends of the metal rods 905 and are in contact with each other;

[0058] Furthermore, the line dividing device 12 is mainly used to connect the wire bodies of multiple groups of lamp bodies 503, and the corresponding metal sheets 1203 are in contact with the metal rods 905, so that the lamp bodies 503 are electrically connected, and the lamp bodies 503 will be in an on state. The number of lamp bodies 503 and metal sheets 1203 can be set according to the speed regulation level of the hydraulic pump 4. For example, the hydraulic pump 4 has five speed regulation levels, and each level corresponds to five metal sheets 1203 and lamp bodies 503. Through testing, the specific moving position of the detection component 9 under the five speed regulation levels can be known. According to the specific moving position, the position of the metal sheet 1203 is set. Since the spherical seat 906 of the detection component 9 is partially embedded, the spring 902 of the detection component 9 must also be adaptively selected so that the detection component 9 should not exceed the set range under multiple speed regulation levels. The metal sheet 1203 and the metal rod 905 are made of the same material, and copper is the best.

[0059] Regarding the above-mentioned lamp body 503, since the two warning areas correspond to the oil filling pipe 7 and the oil outlet pipe 8 respectively, when setting the lamp body 503, it is necessary to ensure that the number of lamp bodies 503 in the two warning areas is the same, the positions correspond, and they are arranged horizontally;

[0060] In order to achieve the best presentation effect and recognition, the multiple groups of lamp bodies 503 in each of the two warning areas need to be lamp bodies 503 of different colors, and the lamp bodies 503 of different colors in the two warning areas need to be distributed in a mirror image.

[0061] In summary, for the oil leakage detection of the hydraulic servo motor, the filling device and the detection device are mainly combined so that the filling device has both driving and detection effects. The specific description of driving and detection is as follows:

[0062] S1. Connect the external oil pipes to the external oil pipe ports a501 and b502 on the inspection box 5. Connect the other ends of the external oil pipes to the corresponding oil ports on the hydraulic servo motor. Activate the hydraulic pump 4 through the control console 3. The oil in the oil filling chamber 2 is injected into the motor. The oil then flows back through the motor into the cooling chamber 1. The oil circulates within the motor, driving the piston and ultimately the motor.

[0063] S2. At different speed levels of the hydraulic pump 4, due to the different flow rates, the forces exerted on the spherical seat 906 of the detection assembly 9 during the oil flow process also vary. Under the action of these forces, the spherical seats 906 of the oil inlet pipe 7 and the oil outlet pipe 8 will both generate outward forces according to the magnitude of the forces, causing the spherical seat 906 to move a corresponding distance.

[0064] S3. When ball seat 906 moves, it causes metal rod 905 of connection seat 904 on detection assembly 9 to move a corresponding distance on branching seat 1201. Simultaneously, metal rod 905 contacts corresponding metal sheet 1203 on branching seat 1201, electrically connecting lamp body 503 to it through metal sheet 1203, turning on lamp body 503. When the motor is not leaking oil, the flow rate and oil pressure in oil filling pipe 7 and oil outlet pipe 8 are the same. Therefore, lamp bodies 503 in both warning areas turn on in the same position, confirming normal motor operation.

[0065] S4. When the motor leaks oil, the oil pressure in the oil outlet pipe 8 decreases, reducing the speed of oil backflow and the force generated by the oil flow. Under this force, the position of the ball seat 906 of the detection component 9 moves differently from the position of the ball seat 906 of the detection component 9 at the oil filling pipe 7, resulting in a different opening position of the lamp body 503, thus confirming that the motor is leaking oil.

[0066] S5. When the motor leaks oil, the degree of leakage is inversely proportional to the oil pressure. The force generated when the oil flows back will gradually decrease as the degree of leakage increases. The generated force is insufficient or not enough to drive the spherical seat 906 to move to the position corresponding to the spherical seat 906 on the oil filling pipe 7. At this time, the lamp body 503 on the warning area corresponding to the oil outlet pipe 8 will be in the off state or the turned-on lamp body 503 will be far away from the turned-on lamp body 503 on the warning area corresponding to the oil filling pipe 7. The degree of oil leakage in the motor is determined based on the distance between the lamp bodies 503 in the two warning areas or when the lamp body 503 on the warning area corresponding to the oil outlet pipe 8 is turned off (except when the line is damaged).

[0067] The above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any ordinary technician in this industry can smoothly implement the invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
