Technical Field

[0001] The utility model relates to the technical field of marking machines, and more specifically, it relates to an efficient marking machine for crankshafts. Background Art

[0002] A crankshaft is the main rotating part of an engine. After installing the connecting rod, it can receive the reciprocating motion of the connecting rod and turn it into a cyclic rotary motion. It is an important part of the engine. The rotation of the crankshaft is the power source of the engine and also the power source of the entire mechanical system. After the crankshaft is processed, it needs to be marked, and the marking content includes production date, serial number, shift, etc.

[0003] Such as Figure 4 shown in the crankshaft part 15, which includes a main shaft 1501, and a connecting part 1502 is arranged at the end of the main shaft. The connecting part is composed of two semi-cylinders of different sizes. End faces 1503 are formed at both ends of the connection of the two semi-cylinders. A secondary shaft 1504 is arranged on the outer surface of the smaller semi-cylinder. During the marking process, due to its own characteristics, shape and other factors, when the marking machine marks the crankshaft, the crankshaft cannot be kept stable, making the marking operation not very convenient and resulting in low marking efficiency.

[0004] Therefore, a new technical solution is urgently needed to solve the above technical problems. Content of the Utility Model

[0021] The present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0022] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions facing or away from the geometric center of a specific component.

[0023] As shown in the figure, an efficient marking machine for a crankshaft includes a marking machine body 1. Two conveyor chains 2 arranged side by side are provided at the top of the marking machine body 1. The conveyor chain 2 includes a chain and a motor driving its operation. A plurality of positioning members 3 for positioning the crankshaft are evenly arranged on the outer surface of the conveyor chain 2. A protective cover 4 is further provided on the end surface of the marking machine body 1. Marking heads 5 extending into the protective cover 4 are provided on both sides of the protective cover 4.

[0024] During the marking process, the crankshaft part to be marked is placed in the corresponding positioning member 3, and is transported into the protective cover 4 through the conveyor connection, and the surface of the connecting part is marked by the marking head 5, thereby effectively improving the marking efficiency and marking accuracy.

[0025] The positioning member 3 includes support plates 6 fixedly connected to both sides of the chain. A reinforcing plate 7 is fixedly connected between the tops of the two support plates 6. A support board 8 is fixedly connected to the outer surface of the support plate 6. A V-shaped support groove 9 is formed at the top of the support board 8. By placing the main shaft of the crankshaft part in the support groove 9, the crankshaft part is supported to ensure its horizontal state.

[0026] Positioning bolts 10 are provided on each support board 8 on the outer side of each conveyor chain 2. There are two positioning bolts 10 and they are arranged on both sides of the V-shaped groove. The positioning bolts 10 are screwed into the support board 8 from the inner side and extend out of the outer surface of the support board 8. The connecting part of the crankshaft is located on the outer surface of the support board 8, so that the two end faces of the connecting part are placed on the tops of the two bolts to ensure the angular position of the crankshaft part, thereby improving the accuracy of marking the surface of its connecting part.

[0027] The bottom of the support plate 6 is fixedly connected to a bottom plate 11 horizontally arranged towards the outside, and a detection device is arranged on the surface of one of the bottom plates 11 for detecting the crankshaft on the positioning member 3. The lower surface of the bottom plate 11 is fixedly connected to an L-shaped plate 12 for fixedly connecting to the conveying chain 2. It also includes a controller (not shown in the figure), and the conveying chain 2, the detection device and the marking head 5 are all electrically connected to the controller. The detection device is an infrared sensor. When it detects that there is a crankshaft part on the positioning member 3 and moves to one side of the marking head 5, the marking head 5 performs marking. If no crankshaft part is detected, the conveying chain 2 continues to move.

[0028] On the surface of the marking machine body 1 at the tail end of the conveying chain 2, a downwardly inclined blanking plate 13 is arranged. After the crankshaft part is marked and moves to the tail end of the conveying chain 2, it rolls onto the blanking plate 13 for blanking.

[0029] At the top of the blanking plate 13, there are two vertically arranged pushing plates 14. The pushing plates 14 are respectively located outside the two support plates 8. The side towards the bottom end of the blanking plate 13 is an inclined surface inclined downward, and its top end is arranged at an acute angle. When the crankshaft is conveyed, its main shaft and sub-shaft are located outside the top of the pushing plate 14. After the crankshaft part is marked and moves to the top of the blanking plate 13, under the action of the pushing plate 14, it rolls onto the inclined side of the pushing plate 14 and rolls onto the blanking plate 13 along the inclined side of the pushing plate 14 to ensure the normal blanking of the crankshaft part.

[0030] The specific embodiments are only explanations of the present invention, and they do not limit the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
