[0017] The present utility model will be further described in conjunction with the accompanying drawings.

[0018] Refer to Figures 1 to 5 , the present utility model is an anti-misoperation detection device for the diaphragm of the steering gear cover, including an oil injection head, an end cover, a proximity switch, a base bracket, and a connecting bracket. The inlet of the oil injection head 2 is connected to the oil pipe joint 3. The top surface of the oil injection head 2 is provided with a plurality of oil injection holes. The center of the oil injection head 2 is provided with an installation groove 1. The upper part of the proximity switch 4 is inserted into the installation groove 1, and the detection end of the proximity switch 4 is flush with the top surface of the oil injection head 2. The bottom of the oil injection head 2 is installed with an end cover 5. The end cover 5 is fixed on the upper surface of the base bracket 9. The proximity switch 4 and the base bracket 9 are connected by a fixing nut 6. The base bracket 9 is installed on the horizontal surface of the connecting bracket 10. The vertical surface of the connecting bracket 10 is connected to the driving mechanism.

[0019] For the convenience of connection and position adjustment, the end cover 5 is provided with a connection hole 7, the base bracket 9 is provided with a horizontal waist-shaped hole 8, and the vertical surface of the connecting bracket 10 is provided with a vertical waist-shaped hole 13. The base bracket 9 and the connection hole 7, the connecting bracket 10 and the horizontal waist-shaped hole 8, and the driving mechanism and the vertical waist-shaped hole 13 are connected by fasteners. The settings of the horizontal waist-shaped hole 8 and the vertical waist-shaped hole 13 are for the convenience of changing the type and adjusting the detection points.

[0020] In order to facilitate the grease lubrication provided by the oil filling head 2 to the diaphragm at the bottom of the steering gear cover 14, the top surface size of the oil filling head 2 matches the outer diameter of the steering gear cover 14. When the steering gear cover 14 covers the top surface of the oil filling head 2, the diaphragm at the bottom of the steering gear cover 14 is located within the sensing area of the proximity switch 4, so as to facilitate the detection of whether the diaphragm of the steering gear cover is installed.

[0021] The driving mechanism includes a horizontal cylinder 12 and a vertical cylinder 11. The piston rod of the vertical cylinder 11 is connected to the horizontal cylinder 12, and the piston rod of the horizontal cylinder 12 is connected to the vertical surface of the connecting bracket 10. The horizontal cylinder 12 and the vertical cylinder 11 can respectively realize the horizontal and vertical movement of the oil filling head 2, facilitating the alignment of the oil filling head 2 with the steering gear cover 14.

[0022] When installing the detection diaphragm of the steering gear cover in the present utility model, the piston rod of the horizontal cylinder 12 extends forward, and at the same time, oil is pumped into the oil filling head 2 through the oil pipe joint 3; the vertical cylinder 11 drives the oil filling head 2 to move upward; the oil filling head 2 approaches the steering gear cover 14. While the oil filling head 2 provides grease lubrication to the diaphragm, after the proximity switch 4 detects a signal pulse, it feeds back to the PLC to judge whether there is a diaphragm on the steering gear cover 14. If it exists, each mechanism returns to its original position, and the machine tool presses the diaphragm; if it does not exist, an alarm will be generated, prompting the operator to check and adjust the steering gear cover 14 and the diaphragm and reinstall them.

[0023] By improving the structure of the oil filling head and adding a proximity switch, the present utility model realizes the detection of the diaphragm while providing grease lubrication to the diaphragm, reduces the number of manual inspections by the operator, thereby reducing the personnel load, optimizing the processing rhythm, and reducing the unqualified rate of the finished steering gear. The present utility model has the characteristics of stability, high efficiency, and simple installation.
