Description

Technical Field

[0001] The utility model relates to the field of smearing auxiliary tools, in particular to an auxiliary tool for smearing lubricating oil on the inner wall of a hole. Background Technique

[0002] The key button is in sliding fit with the reserved key hole of the housing part, and lubricating oil needs to be brushed on the inner wall of the hole of the housing part. The lubricating oil can form a lubricating film inside the workpiece, thereby significantly reducing the friction coefficient and wear rate. This helps to protect the surface of the workpiece, extend its service life, and reduce the performance degradation and maintenance costs caused by wear. The method of brushing lubricating oil is to first dip a cotton swab in lubricating oil and then put it into the hole and brush the oil by rubbing against the inner wall of the hole. However, the existing method of brushing oil is manual operation. First, dip a cotton swab in lubricating oil and then brush the lubricating oil onto the inner wall of the hole. When manually brushing lubricating oil, the amount of oil supplied often depends on the experience and feeling of the operator. Therefore, it is very difficult to achieve precise control, which may lead to insufficient or excessive lubrication, affecting the normal operation and service life of the equipment. Moreover, the repetitive actions are inefficient. In view of this, an auxiliary tool for smearing lubricating oil on the inner wall of a hole is provided. Content of the Utility Model

[0017] Please refer to Figures 1-4 As shown in the figure, the purpose of this embodiment is to provide an auxiliary tool for lubricating the inner wall of a hole, including a base plate 4, a motion trajectory bracket 5 fixedly connected to the rear end of the base plate 4, and a rotary cylinder 7 fixedly connected to the back of the motion trajectory bracket 5. A U-shaped trajectory groove is provided on the motion trajectory bracket 5. The rotating shaft of the rotary cylinder 7 is fixedly connected with a rotary swing arm 9. Centered on the rotating shaft of the rotary cylinder 7, the rotary swing arm 9 can rotate between 0° and 180°. A straight groove is provided on the rotary swing arm 9;

[0018] It further includes a Z-axis up-down mechanism 10. The upper part of the transmission plate 1004 on the Z-axis up-down mechanism 10 is rotatably connected with a transmission shaft 8. The transmission shaft 8 sequentially passes through the U-shaped trajectory groove of the motion trajectory bracket 5 and the straight groove of the rotary swing arm 9, and is rotatably connected to the transmission plate 1004. Two rolling bearings 811 are fixedly connected to the transmission shaft 8, and the rolling bearings 811 are respectively placed in the straight groove of the rotary swing arm 9 and the U-shaped trajectory groove of the motion trajectory bracket 5.

[0019] The workpiece placement mechanism 2 is fixedly connected to the right end of the base plate 4. A workpiece 1 is fixed on the workpiece placement mechanism 2. A switch 3 is fixedly connected to the right side of the workpiece placement mechanism 2. It should be noted that the switch 3 is connected to the rotary cylinder 7 through internal circuits.

[0020] The motion trajectory bracket 5 is fixedly connected to the rear end of the base plate 4. A horizontal slide rail 611 is fixedly connected to the lower part of the motion trajectory bracket 5. A horizontal slider 612 is slidably arranged in the horizontal slide rail 611. The horizontal slider 612 is fixedly connected to the back plate 1001. The horizontal slide rail 611 and the horizontal slider 612 form an X-axis left-right mechanism 6.

[0021] A vertical slide rail 1002 is fixedly connected to the backplane 1001. A vertical slider 1003 is slidably arranged in the vertical slide rail 1002. A drive plate 1004 is fixedly connected to the vertical slider 1003. The backplane 1001, the vertical slide rail 1002, the vertical slider 1003 and the drive plate 1004 together form a Z-axis up-and-down mechanism 10.

[0022] A cotton swab fixing frame 1101 is fixedly connected to the front end of the drive plate 1004 of the Z-axis up-and-down mechanism 10. An oil-brushing cotton swab 11 is arranged on the cotton swab fixing frame 1101.

[0023] A hole is opened at the left end of the base plate 4. An oil container 12 is arranged in the hole. A U-shaped track groove is opened on the movement track bracket 5. The center distance between the two end points of the groove opening is equal to the distance from the oil container 12 to the workpiece hole.

[0024] Working principle: Place the workpiece 1 on the workpiece placement mechanism 2. The rotating shaft of the rotating cylinder 7 is connected to the rotating rocker arm 9. Centered on the rotating shaft of the rotating cylinder 7, the rotating rocker arm 9 can rotate between 0° and 180°. The rotating rocker arm 9 is provided with a straight slot. The transmission shaft 8 is driven by a rolling bearing 811 in contact with the rotating rocker arm 9. The transmission shaft 8 sequentially passes through the U-shaped track groove of the motion track bracket 5 and the straight slot of the rotating rocker arm 9, and is then connected to the transmission plate 1004 of the Z-axis up and down mechanism 10. The motion track bracket 5 is provided with a U-shaped track groove, and the center distance between the two end points of the groove opening is equal to the distance from the oil filling container 12 to the workpiece hole. The width of the straight slot matches the rolling bearing 811 on the transmission shaft 8. After pressing the switch 3, the rotation of the rotating cylinder 7 drives the rotation of the rotating rocker arm 9. The rotating rocker arm 9 transmits the force to the transmission plate 1004 of the Z-axis up and down mechanism 10 through the transmission shaft 8. Since the transmission shaft 8 passes through the U-shaped track groove of the motion track bracket 5 and the straight slot of the rotating rocker arm 9, and the two rolling bearings 811 on the transmission shaft 8 are respectively placed in the straight slot of the rotating rocker arm 9 and the U-shaped track groove of the motion track bracket 5, the rotating rocker arm 9 will drive the transmission shaft 8 to move along the U-shaped track groove during rotation. Also, due to the existence of the rolling bearing 811, the transmission shaft 8 will not rotate along with the rotation of the rotating rocker arm 9, but only move along the U-shaped track groove. And the horizontal slider 612 is fixedly connected to the back plate 1001, and a vertical slide rail 1002 is fixedly connected to the back plate 1001. A vertical slider 1003 is slidably arranged in the vertical slide rail 1002, and a transmission plate 1004 is fixedly connected to the vertical slider 1003. The transmission plate 1004 and the transmission shaft 8 are rotationally connected. Therefore, the transmission shaft 8 will drive the movement while moving. So when the transmission shaft 8 moves in the upper and lower sections of the U-shaped track groove, it will drive the Z-axis up and down mechanism 10 to move vertically, and when it moves in the horizontal section of the U-shaped track groove, it will drive the Z-axis up and down mechanism 10 to move horizontally, thus realizing vertical up and down and left and right parallel movements. The oil-brushing cotton swab 11 is installed on the Z-axis up and down mechanism 10 and moves together with the Z-axis up and down mechanism 10. Also, since the center distance between the two end points of the groove opening of the U-shaped track groove is equal to the distance from the oil filling container 12 to the workpiece hole, the oil-brushing cotton swab 11 can dip oil in the oil filling container 12 during the entire movement process, return along the original path after oil-brushing, and apply lubricating oil to the inner wall of the outer shell part hole. This cycle repeats to achieve the effect of automatic lubricating oil application. And since the oil-brushing cotton swab 11 is used for oil dipping and application each time, the amount of application can also be ensured to be uniform each time.

[0025] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model.
