[0002] The cylinder head, made of cast iron or aluminum alloy, serves as the mounting base for the valve train and the sealing cover for the cylinder. Its function is to ensure a tight seal for compressed gas and provide a gas flow path. Due to its complex structure and high machining precision, cylinder heads are typically manufactured using multiple CNC machining centers. This means that after the workpiece is machined in one center, it must be removed and placed in a subsequent center.

[0049] 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.

[0050] As shown in the figure, an automatic production line for cylinder heads includes:

[0051] Ground track 9;

[0052] a mobile assembly 8 movably mounted on a ground track 9 , having a turntable 804 for mounting the robot 6 thereon;

[0053] The robot 6 is mounted on the turntable 804 and is capable of rotating about a vertical axis under the action of the turntable 804 and moving along the length direction of the ground track 9 driven by the moving assembly 8;

[0054] A feeding mechanism 1 is provided at one end of a ground track 9;

[0055] A feeding mechanism 5 is provided at the other end of the ground track 9;

[0056] There are multiple processing machine tools 4, and the multiple processing machine tools 4 are distributed along both sides of the ground track 9. In this example, the processing machine tools 4 are CNC machining centers, and there are six of them, which are arranged in groups of three on the same side. The ground track 9 is between two groups of processing machine tools 4. In this way, the robot 6 can move on the ground track 9 to the front of the designated processing machine tool 4, thereby realizing the transfer of the workpiece.

[0057] The cylinder head workpiece further includes a rotating mechanism 2 disposed between two processing machines 4 , and the rotating mechanism 2 is configured to rotate the cylinder head workpiece to a specified angle.

[0058] The rotating mechanism 2 includes:

[0059] The workbench 202 has a downwardly recessed concave area 2021 on its surface. This configuration is to form the workbench 202 into a concave dish or plate-like structure. When the cylinder head is placed on top of the workbench 202, debris such as cutting fluid generated during machining of the cylinder head can be collected on the surface of the workbench 202.

[0060] The support plate 213 is rotatably mounted on the surface of the workbench 202, and the downward projection of the support plate 213 is located in the concave area 2021 of the workbench 202. This arrangement can prevent debris such as cutting fluid from falling outside the concave area 2021;

[0061] The positioning pins 214 are fixed to the surface of the support plate 213 and are configured to accurately position the cylinder head when it is placed on the support plate 213. There are multiple positioning pins 214, which are used to cooperate with and insert into the through holes on the surface of the cylinder head to achieve precise positioning.

[0062] The rotating mechanism 2 further includes a frame 201 , and a workbench 202 is fixed above the frame 201 , wherein support feet 203 are installed at the four corners below the frame 201 , which can be used to level and support the entire turning device.

[0063] The rotating mechanism 2 also includes a rotating frame 212 located above the workbench 202. The rotating frame 212 is a U-shaped structure with the opening facing upward. The support plate 213 is installed at the top of the rotating frame 212. On the one hand, the rotating frame 212 can raise the height of the support plate 213 to facilitate the robot 6 to grasp and place the cylinder head. On the other hand, the rotating frame 212 is a U-shaped structure, so that the middle part is in a hollow state, which not only reduces the overall weight but also prevents interference problems when the robot 6 grasps. A driving component for driving the rotating frame 212 and the support plate 213 to rotate is installed on the workbench 202.

[0064] In this example, there are two support plates 213, which are respectively installed on both sides of the top of the rotating frame 212, and there is a gap between the two support plates 213. Specifically, the positioning pin 214 is installed at the near-point surface position of the two support plates 213, so that the cylinder head can be placed just above the gap between the two support plates 213, thereby facilitating the robot 6 to place and grasp it.

[0065] The driving assembly includes a rotating shaft 211 rotatably mounted in the middle of the workbench 202, the upper end of the rotating shaft 211 is connected to the rotating frame 212, and the lower end of the rotating shaft 211 is synchronously rotated and connected to a rotating frame 206 with a V-shaped structure. A first cylinder 204 is mounted on the frame 201, and the telescopic rod of the first cylinder 204 is hinged to the rotating frame 206. The rotating frame 206 can swing under the action of the first cylinder 204. A mounting frame 205 is fixed on the frame 201, and the end of the first cylinder 204 is hinged to the mounting frame 206. 05, specifically, the first cylinder 204 can swing horizontally relative to the mounting frame 205, that is, the center of swing is perpendicular to the horizontal plane, and the telescopic rod end of the first cylinder 204 is hinged on the rotating frame 206, specifically hinged at the outer end of the rotating frame 206. In this way, the swinging effect of the rotating frame 206 can be achieved when the first cylinder 204 is working. The swinging of the rotating frame 206 simultaneously drives the upper rotating shaft 211, the rotating frame 212, and the support plate 213 to rotate synchronously, thereby achieving the effect of flipping the cylinder head on the support plate 213.

[0066] A bearing sleeve 208 is fixed below the workbench 202, and the rotating shaft 211 is rotatably installed in the bearing sleeve 208 through a bearing. Specifically, the bearing sleeve 208 is fixed below the workbench 202 by bolts, and two bearings are installed in the bearing sleeve 208. An end cover 210 is installed at the upper end of the bearing sleeve 208. The end cover 210 is used to contact the outer ring of the bearing to play a limiting effect. This structure and working principle of realizing the rotation of the rotating shaft 211 through a bearing are conventional means in the prior art and will not be elaborated on here.

[0067] A fixed plate 207 is installed at the lower end of the bearing sleeve 208, and two sets of positioning buffer devices for the rotating frame 206 are installed on the lower surface of the fixed plate 207. The positioning buffer devices are used to limit the extreme swing position of the rotating frame 206 and monitor the real-time position of the rotating frame 206.

[0068] The positioning buffer device includes a buffer 216 and a first sensor 217. The working heights of the buffer 216 and the first sensor 217 are both located on the swing trajectory of the rotating frame 206. Specifically, the buffer 216 is a hydraulic buffer 216. In this example, the working end of the hydraulic buffer 216 faces the outer surface of the rotating frame 206. When the V-shaped outer wall of the rotating frame 206 contacts the buffer 216, it is used to provide a certain buffering effect on the rotating frame 206, thereby preventing the rotating frame 206 from stopping suddenly and causing the upper cylinder head to shake (because the cylinder head is simply placed on the support plate 213 and is not pressed against it, the buffer 216 can provide a buffering effect); more specifically, in this example, the first sensor 217 is a proximity switch, which is used to monitor whether the V-shaped rotating frame 206 has rotated into place. When the rotating frame 206 rotates to the first limit position and the second limit position, the proximity switch can detect the position signal, thereby sending a corresponding signal to the control system of the robot 6, and the robot 6 then performs the next action.

[0069] A second sensor 215 for monitoring the position of the cylinder head is installed above the support plate 213. In this example, the second sensor 215 is an infrared transmitter and an infrared receiver, which are arranged at the upper edge positions of the two support plates 213 and facing each other. When the cylinder head is placed on the support plate 213, the signal emitted by the infrared transmitter is blocked by the cylinder head, and thus a signal instruction can be sent to the control system of the robot 6.

[0070] When the rotating mechanism 2 is in use, the rotating mechanism 2 is located between two processing steps of the cylinder head. When the robot 6 takes the cylinder head out from the processing station of the previous process, it can first place the cylinder head on the support plate 213. During the placement process, the positioning pin 214 is inserted into the through hole on the lower surface of the cylinder head for precise positioning. When the placement is completed, the second sensor 215 sends a command to the control system of the robot 6, so that the first cylinder 204 is started, and the telescopic cylinder of the first cylinder 204 extends forward to drive the rotating frame 206, the rotating shaft 211, the rotating frame 212, the support plate 213 and the cylinder head to rotate synchronously. When rotated to the specified position, the buffer 216 can contact the rotating frame 206 to achieve a buffering effect, and the first sensor 217 can monitor the position of the rotating frame 206, thereby sending a signal to the control system of the robot 6. At this time, the robot 6 grabs the cylinder head that has been rotated on the support plate 213 and places it in the processing station of the next process to complete the entire rotation work.

[0071] The loading mechanism 1 and the unloading mechanism 5 both include a conveyor frame 501, which has a plurality of equally spaced and rotatable conveyor rollers 502, wherein the conveyor rollers 502 are mounted on the conveyor frame 501 using bearings, and a sprocket or gear set is mounted at one end of the conveyor roller 502. One of the conveyor rollers 502 at the end is driven by a motor. After the motor is started, all the conveyor rollers 502 can be rotated, thereby transporting the cylinder head placed on the conveyor roller 502. This conveying structure and principle belong to conventional technical means in the prior art and will not be elaborated on here.

[0072] There are limit rods 514 arranged along the length direction of the conveying roller 502 on both sides above the conveying frame 501 and above the conveying roller 502. In this paper, fixed plates 513 are installed on both sides of the upper surface of the conveying frame 501. The surface of the fixed plate 513 is provided with a strip hole 51301. The limit rod 514 is installed at the end position of the fixed plate 513. The provision of the strip hole 51301 can adjust the position of the fixed plate 513 on the conveying frame 501, thereby adjusting the position of the limit rod 514 to meet the positioning effect of cylinder heads of different widths.

[0073] The end of the conveying frame 501 has a pad 511 and a push rod 504 that can pass through the gap between two adjacent conveying rollers 502 up and down, and is used to achieve a lifting effect when the cylinder head is positioned.

[0074] A fixing frame 506 is installed below the conveying frame 501 and near the end of the conveying frame 501, wherein a mounting plate 508 is connected to the top of the fixing frame 506, and the mounting plate 508 is installed on the conveying frame 501. A second cylinder 507 is installed in the middle of the fixing frame 506, and a lifting plate 509 is installed at the end of the telescopic rod of the second cylinder 507. The insertion rod 512 is vertically installed on the surface of the lifting plate 509, and a lifting frame 510 is installed on the surface of the lifting plate 509. The pad 511 is installed on the surface of the lifting frame 510. When working, the second cylinder 507 can drive the lifting plate 509 to move up and down, and the lifting plate 509 drives the pad 511 and the insertion rod 512 to move up and down.

[0075] There are two pads 511 and two insertion rods 512. The highest point of the insertion rod 512 is higher than the upper surface of the pad 511. More specifically, the two pads 511 are located on the outside of the two insertion rods 512. The two pads 511 are used to support the two ends of the cylinder head, so that the supporting effect is more stable. The two insertion rods 512 are used to be inserted into the through holes on the surface of the cylinder head, so that the insertion rods 512 act as positioning pins 214, making the position of the cylinder head more precise, so as to meet the subsequent robot 6's precise grasping of the cylinder head.

[0076] The upper end of the insertion rod 512 is provided with a tapered portion 51201 for more convenient and smooth insertion into the through hole of the cylinder head.

[0077] A horizontal frame 505 is installed at the end position of the conveying frame 501, and a horizontally arranged push rod 504 is installed on the horizontal frame 505. When the cylinder head moves to the end of the conveying frame 501, the push rod 504 can contact the cylinder head to limit the cylinder head from moving further. There are two push rods 504, and the push rods 504 can be used to limit the horizontal position of the cylinder head.

[0078] The device also includes a dirt collecting trough plate 503 installed on the conveying frame 501 and located below the conveying roller 502, that is, the dirt collecting trough plate 503 is located directly below the conveying roller 502, 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.

[0079] The working principle of the feeding mechanism 1 is as follows: the cylinder head is placed on the conveying roller 502, and the cylinder head is conveyed by the conveying roller 502. When it is conveyed to the end position, the cylinder head can contact the push rod 504 to stop conveying, and then the second cylinder 507 is started, so that the pad 511 and the insertion rod 512 pass through the gap between the conveying rollers 502 and move upward, wherein the insertion rod 512 is inserted into the through hole on the surface of the cylinder head to achieve precise positioning, and the pad 511 is used to lift the cylinder head so that the cylinder head and the conveying roller 502 are separated from each other. At this time, the robot 6 can grab the cylinder head at this specific position to complete the entire conveying work. The principle of the unloading mechanism 5 is opposite to that of the above-mentioned loading mechanism 1. First, the robot 6 places the grabbed cylinder head on the pad 511. During the placement process, the insertion rod 512 can be inserted into the through hole on the surface of the cylinder head. Then the second cylinder 507 drives the cylinder head to move downward, so that the cylinder head contacts the conveying roller 502. Under the transportation of the conveying roller 502, the cylinder head is guided out of the production line.

[0080] Guide rails are installed on both sides of the ground track 9 along its length direction;

[0081] The moving assembly 8 includes a support plate 801, on both sides of which sliders 802 are installed, and the sliders 802 slide in conjunction with the guide rails; a turntable 804 is installed on the surface of the support plate 801 through bearings; a first water collecting tray 803 and a second water collecting tray 805 are installed above the support plate 801, and the second water collecting tray 805 is located at the tail of the support plate 801 and the upper end is connected to a placement platform 806 through a column, and the cylinder head can be placed on the placement platform 806; a drive motor 808 is installed on the surface of the support plate 801, and the shaft end of the drive motor 808 is connected to a gear, and the gear is meshed with a rack installed on the ground track 9.

[0082] The moving assembly 8 is mainly used to drive the robot 6 to move to a designated position, so that the robot 6 can grab and place the cylinder head to complete the operation of automated transfer. Specifically, after the drive motor 808 is started, the gear connected to its end can engage with the rack on the ground track 9 to achieve the overall movement of the pallet 801, and the robot 6 can be moved to a designated position on the ground guide rail. When transporting the workpiece, the workpiece can be placed on the placement platform 806 on the top of the pallet. As an intermediate transition, the first water tray 803 and the second water tray 805 can hold the cutting fluid during the machining process of the workpiece to avoid the problem of a dirty and messy working environment. A water flow plate 807 is installed on the bracket above the second water tray 805. The water flow plate 807 is used to guide liquids such as cutting fluid to the second water tray 805.

[0083] It also includes a drain box 3 arranged between two processing machines 4, in which the workpiece completed in the previous process can be placed in the drain box 3, and the cutting fluid is used to flow into the drain box 3 under the action of gravity. The structure and principle of the drain box 3 belong to the conventional design in the prior art and will not be elaborated here.

[0084] It also includes an inspection platform 7 arranged on one side of the end of the ground track 9, and a marking machine 12, an operating cabinet 11, and a control cabinet 10 arranged on the other side of the ground track 9. The inspection platform 7 is mainly used to place the workpiece on the platform and manually inspect the appearance, size, etc. of the workpiece to determine whether it is qualified; the marking machine 12 is used to label the workpiece, and the robot 6 is also used to place the workpiece at the designated position of the marking machine 12 for marking. The operating cabinet 11 and the control cabinet 10 are used to implement the circuit control work of the entire production line, which can be controlled by a PLC controller. The structure and principle of this are also conventional means for implementing circuit control in the existing technology and will not be elaborated on here.
