DETAILED DESCRIPTION

[0028] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The following embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to the following embodiments.

[0029] Example 1

[0030] A limiter oil injection device, such as Figures 1-2 As shown, it includes a limiter fixture 1, an oil injection assembly 2, a sensor assembly 3, a support plate 4, a support column 5 and an electric cylinder 6, which are used to inject oil into the limiter 7. The limiter 7 includes a limiter housing 71 and a limiter limit arm 72.

[0031] Specifically, the limiter clamp 1 includes a shell fixing clamp 11 for fixing the limiter shell 71 and a limiter arm fixing clamp 12 for fixing the limiter limit arm 72, the oil filling assembly 2 includes a shell oil filling assembly 21 for filling oil into the limiter shell 71 and a limiter arm oil filling assembly 22 for filling oil into the limiter limit arm 72, and the sensor assembly 3 includes an error-proofing sensor 31 for detecting the presence or absence of a limiter and an in-position sensor 32 for detecting whether the limiter has reached a specified position.

[0032] like Figure 3 As shown, the limiter housing 71 is fixed on the support plate by a housing fixing fixture 11 arranged on the support plate 4, and two housing oil filling assemblies 21 are symmetrically arranged on both sides of the limiter housing 71. The housing oil filling assembly 21 includes a housing oil filling gun 211 and a housing oil filling cylinder 212. The housing oil filling cylinder 212 can drive the housing oil filling gun 211 to move toward the oil filling hole on the limiter housing 71 for oiling.

[0033] like Figure 4As shown, the limiter limit arm 72 connected to the limiter housing 71 passes through the support plate 4 and is suspended below the support plate 4. A support column 5 is connected below the support plate 4. An electric cylinder 6 is arranged on the support column 5. The electric cylinder 6 is connected to the limiter arm fixing fixture 12 and the limiter arm oil injection assembly 22. The electric cylinder 6 can adjust the height of the limiter arm fixing fixture 12 and the limiter arm oil injection assembly 22 up and down to adapt to different positions of the limiter limiter arm 72. The limiter arm oil injection assembly 22 includes a limiter arm oil injection gun 221 and a limiter arm oil injection cylinder 222 that drives the limiter arm oil injection gun 221 to move horizontally. The limiter arm oil injection cylinder 222 is fixed on the bottom plate, and the bottom plate is connected to the limiter arm fixing fixture 12.

[0034] In order to improve the controllability of the device, the error-proofing sensor 31 is set below the shell fixing fixture to detect the presence or absence of the limiter shell 71, and the in-place sensor 32 is set below the limiter arm fixing fixture 12 to detect whether the limiter limiter arm 72 is in place.

[0035] Example 2

[0036] A stopper oiling device also includes an electric control box and a control panel, and the rest of the structure is the same as that of Example 1. When the stopper 7 is offset, that is, the stopper arm 72 is not in place, the control panel will display an alarm indicating that the part is not in place.

[0037] When the device of this embodiment is working, the limiter cover (limiter housing 71) and the limiter shaft (limiter limiter arm 72) are manually assembled and placed in the device, and the two ends of the start button limiter housing 71 are filled with oil, and the bottom hole of the bottom limiter shaft is filled with oil. The above-mentioned positioning reference method is tooling positioning, the sensor is positive and negative error-proof detection, and the oiling accuracy of the oiling gun is 0.02g.

[0038] The working principle is:

[0039] Step 1: Turn on the device normally and select the corresponding product on the touch screen;

[0040] Step 2: manually put the product in and press the stopper fixture 1 tightly;

[0041] Step 3: Start with both hands;

[0042] Step 4: Automatically detect the presence of products;

[0043] Step 5: Automatically detect that the product is in place;

[0044] Step 6: The shell oil filling cylinder 212 and the limit arm oil filling cylinder 222 drive the oiling gun to the oiling position;

[0045] Step 7: Start filling oil at the same time;

[0046] Step 8: Return to position;

[0047] Step 9: Manually remove the product.

[0048] The above description of the embodiments is to facilitate the understanding and use of the present invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work.
