[0030] Example

[0031] like Figure 1An automatic oiling machine is shown, including a machine base 10, a manual press 20, an oiling fixture 60, a material feeding sensing mechanism 30, a pressing detection mechanism 40, and an oil supply mechanism 50. The manual press is mounted above the machine base. The bottom of the main shaft 21 of the manual press is connected to a positioning pressing block 23 for pressing products. The oiling fixture is located above the machine base and corresponds to the press head of the manual press. The material feeding sensing mechanism includes a left-hand sensing component 31 and a right-hand sensing component 32 respectively located on opposite sides of the oiling fixture on the machine base. The pressing detection mechanism includes a handle sensing component 41 located on the main shaft box of the manual press. The oil supply mechanism includes a housing 51, an oil storage bottle 52, and an automatic oil squeezing component 53. The housing is located on one side above the machine base, the oil storage bottle is located on one side of the housing and connected to the oiling fixture through a pipeline 54, and the automatic oil squeezing component is located above the oil storage bottle and connected to a piston 55 to the inside of the oil storage bottle.

[0032] In addition to the above structure, this application also includes a PLC controller 70 for overall control and a counter 80 for counting the number of times the left-hand sensing component and the right-hand sensing component are sensed, the counter being electrically connected to the PLC controller.

[0033] The general principles of this application will be explained below:

[0034] The operator first places the rotating shaft component into the oiling fixture. The left and right sensing components and the right-hand sensing component simultaneously sense the component once. The PLC controller then drives the automatic oiling component to squeeze the grease through the pipeline onto the surface of the rotating shaft component within the oiling fixture. Afterward, the operator manually operates the manual press to press the finally assembled rotating shaft component together. At this point, the handle sensing component senses the component once, and the PLC controller resets the previous count to zero. The count restarts the next time the rotating shaft is assembled. Furthermore, once the counter reaches the set value, even if the left and right sensing components sense the operator's left and right hands again, the counting stops, and the automatic oiling component ceases operation.

[0035] refer to Figures 2-4As shown, the oiling fixture of this application includes a base 61 mounted above the machine tool, a carrier seat 62 mounted above the base, a positioning carrier 63 mounted above the carrier seat, an assembly hole 64 coaxially formed inside the carrier seat and the positioning carrier, an oil injection needle 65 located inside the assembly hole and closed at its lower end, an oil injection hole 651 formed on one side above the oil injection needle, a return spring 68 located on the machine tool at the bottom of the oil injection needle, a clearance groove 621 formed on one side of the carrier seat, and a pipeline connector 66 connected to the oil injection needle outside the clearance groove. In specific implementation, after the operator places the rotating shaft component onto the positioning carrier, the left-hand sensing component and the right-hand sensing component simultaneously sense... Once the PLC controls the oil squeezing component to operate, the oil squeezed out by the automatic oil squeezing component will enter the oil injection needle through the pipeline and then exit through the oil injection hole, falling onto the surface of the rotating shaft component. After the oil injection of the rotating shaft component is completed and all components are on the positioning carrier, the operator operates the manual press to press the rotating shaft. During this process, the return spring will compress downwards, and the pipeline and pipeline connector will descend together until the rotating shaft is successfully pressed. After the rotating shaft is pressed, the operator will control the positioning pressing block of the manual press to reset, and the return spring will drive the oil injection needle, pipeline and pipeline connector to automatically reset.

[0036] Based on the previous embodiment, in order to position and install the return spring, this application provides a circular blind groove on the base, and a plug shaft 67 is provided at the bottom of the oil injection needle. One end of the return spring is located in the circular blind groove 611, and the other end is plugged into the outer ring of the plug shaft. Based on this structure, when the manual press drives the positioning pressing block to press the product shaft, the return spring will extend and retract smoothly, avoiding slippage.

[0037] refer to Figure 1 As shown, the left-hand sensing component and the right-hand sensing component of this application have the same structure, respectively including a first L-shaped plate 311 fixed to the machine base by a first electromagnet 314, two oblong holes 3111 opened on the vertical part of the first L-shaped plate, a second L-shaped plate 312 fixed to the first L-shaped plate by screwing a bolt (not shown in this application) through the oblong holes on its vertical part, and a diffuse sensor 313 located below the second L-shaped plate. In real time, based on the cooperation between the bolt and the oblong holes, the diffuse sensor of this application can be height adjusted, and can realize the sensing of the operator's left or right hand according to the working properties of diffuse reflection.

[0038] Same reference Figure 1As shown, the handle sensing component of this application includes a third L-shaped plate 411 fixed to the spindle box of a manual press via a second electromagnet 412 and a photoelectric sensor 413 disposed on the transverse portion of the third L-shaped plate. In the initial state, the photoelectric sensor of this application emits photoelectric light directly onto the handle 22 of the manual press. If the photoelectric sensor emits photoelectric light that does not fall onto the handle, it indicates that the handle of the manual press has been activated, that is, the shaft has been pressed.

[0039] refer to Figure 5 As shown, in a preferred embodiment, the automatic oil squeezing assembly of this application includes an electric cylinder disposed above the housing. The inner wall of the electric cylinder is provided with a Hall sensor (not shown in this application) for detecting the stroke of the push rod. It should be noted that electric cylinders with Hall sensors are known technology and will not be described in detail here. By detecting the stroke of the push rod through the Hall sensor, the oil level in the oil storage bottle can be determined, so that the operator can know the amount of oil stored in the oil storage bottle in real time and thus determine whether to perform the refueling action.

[0040] Continue to refer to Figure 5 As shown, in another preferred embodiment, the push rod of the electric cylinder of this application is connected to the piston through a pressure sensor 56. In the specific implementation process, if the pressure value detected by the pressure sensor is greater than the set value, it indicates that the pipeline or the oil needle is blocked. At this time, the operator can quickly perform maintenance.

[0041] In the description of this specification, the references to terms such as "an embodiment," "example," "specific example," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

They should not be used to limit the scope of protection of this application. All equivalent changes or modifications made in accordance with the spirit and essence of this application should be included within the scope of protection of this application.
