Description

Technical Field

[0001] This utility model belongs to the field of electrostatic oiling technology, specifically relating to a mechanism for quickly switching oiling parameters of an electrostatic oiling machine. Background Technology

[0002] In industrial sectors such as machinery manufacturing, automobile assembly, and metal processing, the friction pairs of automated equipment require regular and quantitative application of lubricating oil or grease to ensure their normal operation and extend their service life. During this process, it is often necessary to quickly switch parameters such as the amount of oil applied based on different lubrication points or workpiece types. Therefore, the demand for automated oiling devices capable of flexibly switching oiling parameters is becoming increasingly urgent.

[0003] In existing technologies, servo motors, stepper motors, or proportional valves are used as core control components, with multiple sets of parameter programs preset through a PLC controller. When parameters need to be switched, the control system issues a command to drive the actuator, thereby changing the oil injection volume. The drawbacks of this approach are: the system is complex, containing numerous electrical components and sensors, leading to high manufacturing and maintenance costs; furthermore, in harsh industrial environments with high temperature, high humidity, high dust, or strong electromagnetic interference, the reliability of electronic components significantly decreases, increasing the failure rate; finally, its operation and maintenance require specialized personnel, demanding a high level of technical skill from on-site workers. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model provides a mechanism for rapidly switching oiling parameters in an electrostatic oiling machine, thereby solving the problems mentioned in the background technology.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A mechanism for rapidly switching oiling parameters in an electrostatic oiling machine includes a push rod. The top of the push rod is connected to a movable seat, and both sides of the movable seat are threaded to a lead screw. The top of the lead screw is connected to a front support seat, and the end is hinged to a rear support seat. A gear A is fixedly connected to the lead screw below the front support seat. Gear A meshes with gear B, and gear B is fixedly connected to the output end of a motor. The lower part of the push rod is sleeved in a sleeve, which is embedded in the rear support seat. The bottom end of the sleeve is interference-fitted to a hydraulic cylinder. A top plate is sleeved on the lower end of the hydraulic cylinder. The edge of the top plate is connected through a pipe. The bottom end of the top plate is fixedly connected to an L-shaped rod, and the end of the L-shaped rod is inserted through a graduated groove.

[0007] Furthermore, the fitting includes an oil outlet pipe and an oil inlet pipe. The oil outlet pipe is connected to a one-way valve A, and the oil inlet pipe is connected to a one-way valve B. The path of the one-way valve A is away from the oil cylinder, and the path of the one-way valve B is towards the oil cylinder.

[0008] Furthermore, the bottom end of the one-way valve A is connected to the nozzle, and the bottom end of the one-way valve B is connected to the oil tank through an oil pipe. The oil tank is located on the outside of the housing, and the nozzle is located inside the housing.

[0009] Furthermore, a high-voltage electrode is provided on the inner wall of the outer casing, and the front support and rear support are connected to the back side of the outer casing.

[0010] Furthermore, the scale groove is provided with a first sliding groove in the vertical direction, and a plurality of second sliding grooves are provided in the horizontal direction on one side of the first sliding groove, with scale markings below the second sliding grooves.

[0011] Furthermore, when the push rod is vertically downward, it is sleeved inside the oil cylinder and fits against the inner wall of the oil cylinder, and the edge of the top plate fits against the inner side of the oil cylinder.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] 1. This utility model allows for precise control of the effective volume and single-pass oil discharge of the hydraulic cylinder by directly and manually adjusting the position of the L-shaped rod at different positions on the scale groove to set the maximum stroke of the top plate. The entire process is accomplished entirely by simple levers and mechanical positioning structures, resulting in low manufacturing and maintenance costs and significantly improved reliability in harsh industrial environments.

[0014] 2. This utility model realizes multiple parameter presets through multiple positions on the scale groove. The operator can intuitively set and lock the oil injection parameters by manually lifting the L-shaped rod and inserting its front end into the second slide groove at different positions on the scale groove. This reduces the technical level requirements of the operator and effectively improves the work efficiency of switching different parameters. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1:

[0026] like Figure 1-4As shown, this utility model discloses a rapid switching mechanism for oiling parameters of an electrostatic oiling machine. Specifically, it includes a push rod 1, the top end of which is connected to a movable base 2, and both sides of the movable base 2 are threadedly connected to a lead screw 3.

[0027] The top end of the lead screw 3 is connected to the front support seat 4, and the end is hinged to the rear support seat 6. A gear A11 is fixedly connected to the lead screw 3 below the front support seat 4. Gear A11 meshes with gear B12, and gear B12 is fixedly connected to the output end of the motor 13. The lead screw 3 and the moving seat 2 form a transmission assembly that converts the rotational motion of gear A11 into linear lifting motion. Gear A11 and gear B12 form a driving force assembly provided by the motor 13, which is the power source providing the power.

[0028] The lower part of the push rod 1 is sleeved inside the sleeve 5, the sleeve 5 is embedded in the support seat 6, and the bottom end of the sleeve 5 is interference-fitted with the oil cylinder 7. The sleeve 5 is a structural component that provides guidance and support for the push rod 1, and the oil cylinder 7 is a cavity component that contains lubricating oil and completes the oil pressing process.

[0029] Secondly, a top plate 8 is fitted inside the lower end of the oil cylinder 7. The edge of the top plate 8 is connected to the pipe 9 through the pipe. The bottom end of the top plate 8 is fixedly connected to the L-shaped rod 21. The end of the L-shaped rod 21 is inserted into the scale groove 10. The top plate 8 is a control component that changes the effective volume of the oil cylinder 7 and controls the oil discharge volume. The L-shaped rod 21 is an operation and feedback linkage that connects the top plate 8 and the scale groove 10. The scale groove 10 is a mechanical positioning component that presets and locks different oil discharge levels.

[0030] Meanwhile, the fitting 9 includes an oil outlet pipe 901 and an oil inlet pipe 902. The oil outlet pipe 901 is connected to a one-way valve A141, and the oil inlet pipe 902 is connected to a one-way valve B142. The path of the one-way valve A141 is away from the oil cylinder 7, and the path of the one-way valve B142 is towards the oil cylinder 7. The oil outlet pipe 901 and the oil inlet pipe 902 are the inlet and outlet channels for lubricating oil, and the one-way valves A141 and B142 are functional components that ensure unidirectional oil flow and prevent backflow.

[0031] Furthermore, the bottom end of the one-way valve A141 is connected to the nozzle 15, and the bottom end of the one-way valve B142 is connected to the oil tank 16 via an oil pipe. The oil tank 16 is located on the outside of the housing 17, and the nozzle 15 is located inside the housing 17. A high-voltage electrode 18 is provided on the inner wall of the housing 17, and the front support 4 and the rear support 6 are connected to the back side of the housing 17. The nozzle 15 is a functional component that atomizes and sprays lubricating oil, and the high-voltage electrode 18 charges the oil mist so that it can be adsorbed onto the surface of the workpiece. The housing 17 is the main structure that integrates and protects all components.

[0032] Finally, the scale groove 10 is vertically provided with a first slide groove 19, and a plurality of second slide grooves 20 are horizontally provided on one side of the first slide groove 19. The second slide grooves 20 are marked with scales. When the push rod 1 is vertically downward, it is sleeved inside the oil cylinder 7 and fits against the inner wall of the oil cylinder 7. The edge of the top plate 8 fits against the inner side of the oil cylinder 7. The first slide groove 19 is a guide channel for the L-shaped rod 21 to move up and down. The plurality of second slide grooves 20 are preset gears representing different oil injection volumes. The scales are markings for intuitive reading of parameters.

[0033] When using this invention, the operator manually lifts the L-shaped rod 21 upwards according to the required oil volume, causing its end to disengage from the current second slide groove 20 and move upwards along the first slide groove 19. Then, the L-shaped rod 21 is moved laterally, locking its end into the second slide groove 20 corresponding to the target scale on the scale groove 10. This action causes the top plate 8 to rise within the oil cylinder 7 via the L-shaped rod 21, thus preseting the lower stop position of the top plate 8, i.e., setting the effective oil discharge volume of the oil cylinder 7. Then, the motor 13 is started, driving the gear B12 to rotate, which in turn drives the meshing gear A11 to rotate, thereby causing the two lead screws 3 to rotate synchronously. The moving seat 2, threaded with the lead screw 3, moves downwards, pushing the push rod 1 downwards. Push rod 1 presses against top plate 8, increasing the pressure of lubricating oil in the cavity and opening check valve A141. Lubricating oil is sprayed out from nozzle 15 through oil outlet pipe 901. When push rod returns, the volume of the upper cavity of cylinder 7 increases, forming a negative pressure. Under atmospheric pressure, the lubricating oil in oil tank 16 opens check valve B142 and enters the upper cavity of cylinder 7 through oil inlet pipe 902.
