DETAILED DESCRIPTION

[0018] In order to better understand the improvements made by the present invention relative to the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] like Figure 1 As shown in FIG. 4 , an automatic oil immersion device for a camshaft is mainly composed of a bracket 1, an oil immersion basin 9, a side plate 26 and a bottom frame 32. The two side plates 26 are respectively arranged on the left and right sides of the bottom frame 32, the bracket 1 is fixedly installed in the middle of the two side plates 26, and the oil immersion basin 9 is arranged directly below the bracket 1. At the same time, the left and right ends of the two side plates 26 are connected by two support rods to strengthen the overall structural strength.

[0020] A fixing frame 20 is installed on the inner side of each side plate 26 through the support plate 16, and the left and right fixing frames 20 form a pair, and the support plate 16 is provided with a plurality of fixing frames 20 along the front-back extension direction. The top of the fixing frame 20 is evenly provided with a plurality of grooves for placing the camshaft, and a moving frame 21 is arranged in parallel on the inner side of each fixing frame 20, and the moving frame 21 is provided with a groove corresponding to the fixing frame 20.

[0021] The moving frames 21 are connected to the driving assembly through the lifting plate 17 arranged at the bottom. The driving assembly can drive the moving frame 21 to step up and down and step back and forth, and the moving frame 21 is placed under the fixed frame 20 when it is not lifted. The driving assembly is mainly composed of a horizontal cylinder 2 and a vertical cylinder 3. The horizontal cylinder 2 is fixedly connected to the side plate 26 through a cylinder fixed connection plate 28. The vertical cylinder 3 is arranged on a linear bearing 12 driven by the horizontal cylinder 2, and the vertical cylinder 3 drives the lifting plate 17 to move up and down through a vertically arranged guide shaft 11.

[0022] The bracket 1 is mainly composed of a pair of vertical parts vertically arranged on the outside of the two side plates 26 and a horizontal part connecting the top of the vertical part. A driving shaft is vertically arranged in the middle of the horizontal part through the mounting plate 10, and a material support frame 24 is arranged at the bottom of the driving shaft. The fixed frame 20 and the movable frame 21 are both disconnected at the position of the bracket 1. The movable frames 21 on the front and rear sides cooperate with the driving assembly to put the camshaft into or take it out of the material support frame 24, thereby realizing the loading and unloading and relay transportation of the camshaft immersed in oil.

[0023] The material support frame 24 is composed of a crossbar arranged at the bottom of the driving shaft and brackets arranged at both ends of the crossbar, wherein the bracket includes a top mounting plate, a vertical plate, and a bracket with a vertical groove at the bottom, and the distance between the two end trays is greater than the distance between the front and rear side moving frames 21, so that the moving frame 21 can place the camshaft on the bracket. Among them, the driving shaft is preferably a double-rod cylinder, and the material support frame 24 reciprocates up and down under the drive of the cylinder. When the infrared detection device detects the camshaft, the driving shaft drives the material support frame 24 to move up and down to complete the camshaft oiling.

[0024] When the staff places the camshaft on the fixed frame 20 in the rear loading area, the vertical cylinder 3 on the rear side first drives the mobile frame 21 to lift upward. At this time, the height of the mobile frame 21 is greater than the fixed frame 20, and the camshaft is fixed by the corresponding groove on the mobile frame 21. After the camshaft is lifted and fixed by the mobile frame 21, the linear bearing 12 driven by the horizontal cylinder 2 moves forward, so that the camshaft steps one grid relative to the fixed frame 20, and the mobile frame 21 slowly falls back under the action of the vertical cylinder 3. The camshaft is placed on the fixed frame 20. At this time, the mobile frame 21 is placed under the fixed frame 20 and returns to its position backward under the action of the horizontal cylinder 2, completing a stepping motion. Among them, when the mobile frame 21 is driven by the horizontal cylinder 2, the front end groove corresponds to the groove of the material support frame 24. The mobile frame 21 reciprocates under the action of the drive assembly, driving the camshaft to step one grid each time until the infrared detection device detects that the camshaft is placed on the groove of the material support frame 24. After the mobile frame 21 is reset, the drive shaft reciprocates up and down to complete the camshaft oiling. After the camshaft is immersed in oil, the horizontal cylinder 2 in the front unloading area drives the mobile frame 21 to move backward. The groove at the rear end of the mobile frame 21 corresponds to the groove of the material support frame 24. Then the vertical cylinder 3 drives the mobile frame 21 to lift up and hold up the camshaft immersed in oil. At this time, the horizontal cylinder 2 drives the mobile frame 21 to step forward one grid. The mobile frame 21 falls back under the action of the vertical cylinder 3 to complete the loading and unloading and relaying of the camshaft immersed in oil. The oil-immersed camshaft includes an exhaust camshaft 18 and an intake camshaft 19, wherein the exhaust camshaft 18 and the intake camshaft 19 are staggered to prevent the same type of camshafts from being easily bumped when placed adjacently.

[0025] In order to prevent the oil droplets from being carried out by the mobile frame 21 and the material support frame 24 and dripping onto the ground during the automatic oil immersion process of the camshaft, a first oil receiving pan and a second oil receiving pan are respectively provided under the two pairs of fixed frames. A first oil channel 7 connected to the first oil receiving pan 5 and a second oil channel 8 connected to the second oil receiving pan 6 are respectively provided on the left and right sides of the bottom end of the oil immersion basin 9 to further prevent oil dripping.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
