[0002] The cylinder head of an automobile engine, also known as the cylinder head, is a crucial component of the engine, located at the top of the cylinder and enclosing the cylinder chamber. It primarily houses the valves, cylinder head gasket, cooling channels, and other components. The cylinder head ensures a tight seal and provides a flow path for compressed gas, impacting engine performance and efficiency. It is typically made of aluminum alloy or cast iron to withstand high-temperature and high-pressure environments. Due to its complex structure and high machining precision, cylinder heads are typically manufactured using CNC machining centers. Traditionally, this process involves moving the cylinder head to a fixture within the machining center, where the workpiece is clamped securely before the machine is started. However, since the cylinder head itself is heavy, the handling process will consume the physical strength of the personnel and is prone to safety accidents. Therefore, the existing technology also uses robots to carry the workpiece to free up manpower. However, since the robot needs to grab the workpiece at a specified position, and the cylinder head production requires multiple processes, and there is a certain distance between adjacent processes, when the previous process is completed, the workpiece often cannot be placed in the specified position, resulting in the robot being unable to grab it. Therefore, based on the above problems, the inventor proposed a conveying device for automobile engine cylinder head production. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] As shown in the figure, a conveying device for the production of automobile engine cylinder heads includes a conveying frame 1, on which are provided a plurality of equally spaced and rotatable conveying rollers 2, wherein the conveying rollers 2 are mounted on the conveying frame 1 using bearings, and a sprocket or a gear set is mounted at one end of the conveying roller 2. One of the conveying rollers 2 at the end is driven by a motor. After the motor is started, all the conveying rollers 2 can be rotated, thereby conveying the cylinder head placed on the conveying roller 2. This conveying structure and principle belong to conventional technical means in the prior art and will not be elaborated on here.

[0023] There are limit rods 14 arranged along the length direction of the conveyor roller 2 on both sides above the conveyor frame 1 and above the conveyor roller 2. In this invention, fixed plates 13 are installed on both sides of the upper surface of the conveyor frame 1. The surface of the fixed plate 13 is provided with a strip hole 1301. The limit rod 14 is installed at the end position of the fixed plate 13. The provision of the strip hole 1301 can adjust the position of the fixed plate 13 on the conveyor frame 1, thereby adjusting the position of the limit rod 14 to meet the positioning effect of cylinder heads of different widths.

[0024] The end of the conveyor frame 1 is provided with a pad 11 and a push rod 4 that can pass through the gap between two adjacent conveyor rollers 2 up and down, and is used to achieve a lifting effect when the cylinder head is positioned.

[0025] A fixed frame 6 is installed below the conveyor frame 1 and near the end of the conveyor frame 1, wherein a mounting plate 8 is connected above the fixed frame 6, and the mounting plate 8 is installed on the conveyor frame 1. A cylinder 7 is installed in the middle of the fixed frame 6, and a lifting plate 9 is installed at the end of the telescopic rod of the cylinder 7. The insertion rod 12 is vertically installed on the surface of the lifting plate 9, and a lifting frame 10 is installed on the surface of the lifting plate 9. The pad 11 is installed on the surface of the lifting frame 10. When working, the cylinder 7 can drive the lifting plate 9 to move up and down, and the lifting plate 9 then drives the pad 11 and the insertion rod 12 to move up and down.

[0026] There are two pads 11 and two insertion rods 12. The highest point of the insertion rod 12 is higher than the upper surface of the pad 11. More specifically, the two pads 11 are located on the outside of the two insertion rods 12. The two pads 11 are used to support the two ends of the cylinder head, so that the supporting effect is more stable. The two insertion rods 12 are used to be inserted into the through holes on the surface of the cylinder head, so that the insertion rods 12 act as positioning pins, making the position of the cylinder head more precise, which meets the needs of the subsequent robot to accurately grasp the cylinder head.

[0027] The upper end of the insertion rod 12 is provided with a tapered portion 1201 for more convenient and smooth insertion into the through hole of the cylinder head.

[0028] A cross frame 5 is installed at the end position of the conveyor frame 1, and a horizontally arranged push rod 4 is installed on the cross frame 5. When the cylinder head moves to the end of the conveyor frame 1, the push rod 4 can contact the cylinder head to limit the cylinder head from moving further. There are two push rods 4, and the push rods 4 can be used to limit the horizontal position of the cylinder head.

[0029] The device also includes a dirt collecting trough plate 3 installed on the conveyor frame 1 and located below the conveyor roller 2, that is, the dirt collecting trough plate 3 is located directly below the conveyor roller 2, and is mainly used to collect cutting fluid or other debris from the cylinder head during the previous processing process to prevent it from falling directly on the ground.

[0030] When this conveying device for automobile engine cylinder head production is in use, the cylinder head after the previous process is placed on the conveying roller 2, and the cylinder head is conveyed by the conveying roller 2. When it is conveyed to the end position, the cylinder head can contact the push rod 4 to stop conveying, and then the cylinder 7 is started, so that the pad 11 and the insertion rod 12 pass through the gap between the conveying rollers 2 and move upward, wherein the insertion rod 12 is inserted into the through hole on the surface of the cylinder head to achieve precise positioning, and the pad 11 is used to lift the cylinder head, so that the cylinder head and the conveying roller 2 are separated from each other. At this time, the robot can grab the cylinder head at this specific position, completing the entire conveying work.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
