Description

Technical Field

[0001] The utility model belongs to the technical field of cylinder cover conveying, and particularly relates to a rotating device for a cylinder cover. Background Art

[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 the tightness of the compressed gas and provide a gas flow path. Due to its complex structure and high machining precision, cylinder heads are typically manufactured using CNC machining centers. Traditionally, when machining cylinder heads, transfer work is typically performed manually. The cylinder head is placed on a pallet or conveyor rollers, and workers pull the pallet or push the cylinder head on the conveyor rollers to move the workpiece to the next process. However, when the workpiece enters the machining center for clamping and positioning, it often still relies on manual handling, resulting in heavy workload for operators, low safety, and low efficiency.

[0003] To address the aforementioned technical issues, existing technologies utilize robots to automatically transfer workpieces during cylinder head machining. Specifically, the robot's arm can grasp a workpiece and move it from one process to the next. However, due to the different machining locations of the cylinder head in different processes, the previous and next processes require different installation and positioning methods on the CNC machine tool. This necessitates a certain degree of cylinder head rotation. However, the robot's working arm has certain limitations during rotation, making it impossible to achieve the required cylinder head rotation. Therefore, to enable the robot to adjust the gripping position of the cylinder head, the inventors have proposed a cylinder head rotation device. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a rotating device for a cylinder head, which can not only place the cylinder head on a support plate and rotate it at a specified angle, but also use the positioning pins on the support plate to accurately position the cylinder head, so that the cylinder head can stay at the specified position after each rotation. After the robot program debugging is completed, the cylinder head can be grasped at the specified position, which improves the consistency of the cylinder head grasping and is conducive to improving the grasping accuracy and grasping efficiency.

[0026] 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.

[0027] As shown in the figure, a rotating device for a cylinder head includes:

[0028] The workbench 2 has a downwardly recessed concave area 201 on its surface. This configuration is to form the workbench 2 into a concave dish or plate-like structure, so that when the cylinder head is placed on top of the workbench 2, the cutting fluid and other debris generated during the machining of the cylinder head can be collected on the surface of the workbench 2;

[0029] The support plate 13 is rotatably mounted on the surface of the workbench 2, and the downward projection of the support plate 13 is located in the concave area 201 of the workbench 2. This arrangement can prevent debris such as cutting fluid from falling outside the concave area 201;

[0030] The positioning pins 14 are fixed to the surface of the support plate 13 and are configured to accurately position the cylinder head when it is placed on the support plate 13. There are multiple positioning pins 14, which are used to cooperate with and insert into the through holes on the surface of the cylinder head to achieve precise positioning.

[0031] The machine also includes a frame 1 , and a workbench 2 is fixed above the frame 1 .

[0032] Support feet 3 are installed at the four corners below the frame 1 and can be used to level and support the entire turning device.

[0033] It also includes a rotating frame 12 located above the workbench 2. The rotating frame 12 is a U-shaped structure with the opening facing upward. The support plate 13 is installed at the top of the rotating frame 12. On the one hand, the rotating frame 12 can raise the height of the support plate 13 to facilitate the robot to grasp and place the cylinder head. On the other hand, the rotating frame 12 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 grasps. A drive component for driving the rotating frame 12 and the support plate 13 to rotate is installed on the workbench 2.

[0034] In this example, there are two support plates 13, which are respectively installed on both sides of the top of the rotating frame 12, and there is a gap between the two support plates 13. Specifically, the positioning pins 14 are installed at the near-point surface position of the two support plates 13, so that the cylinder head can be placed just above the gap between the two support plates 13, thereby facilitating the robot to place and grasp it.

[0035] The driving assembly includes a rotating shaft 11 rotatably mounted in the middle position of the workbench 2. The upper end of the rotating shaft 11 is connected to the rotating frame 12, and the lower end of the rotating shaft 11 is synchronously rotated and connected to a rotating frame 6 with a V-shaped structure. A cylinder 4 is installed on the frame 1, and the telescopic rod of the cylinder 4 is hinged to the rotating frame 6. The rotating frame 6 can swing under the action of the cylinder 4. Among them, a mounting frame 5 is fixed on the frame 1, and the end of the cylinder 4 is hinged on the mounting frame 5. Specifically, the cylinder 4 can swing horizontally relative to the mounting frame 5, that is, the swing center is perpendicular to the horizontal plane, and the telescopic rod end of the cylinder 4 is hinged on the rotating frame 6, specifically at the outer end position of the rotating frame 6. In this way, the swing effect of the rotating frame 6 can be achieved when the cylinder 4 is working. The swing of the rotating frame 6 simultaneously drives the upper rotating shaft 11, the rotating frame 12, and the support plate 13 to rotate synchronously, thereby achieving the effect of flipping the cylinder head on the support plate 13.

[0036] A bearing sleeve 8 is fixed at the lower position of the workbench 2, and the rotating shaft 11 is rotatably installed in the bearing sleeve 8 through a bearing. Specifically, the bearing sleeve 8 is fixed to the bottom of the workbench 2 by bolts. Two bearings are installed in the bearing sleeve 8, and an end cover 10 is installed at the upper end of the bearing sleeve 8. The end cover 10 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 11 through a bearing are conventional means in the prior art and will not be elaborated here.

[0037] A fixed plate 7 is installed at the lower end of the bearing sleeve 8, and two sets of positioning buffer devices for the rotating frame 6 are installed on the lower surface of the fixed plate 7. The positioning buffer devices are used to limit the extreme swing position of the rotating frame 6 and monitor the real-time position of the rotating frame 6.

[0038] The positioning buffer device includes a buffer 16 and a first sensor 17. The working heights of the buffer 16 and the first sensor 17 are both located on the swing trajectory of the rotating frame 6. Specifically, the buffer 16 is a hydraulic buffer 16. In this example, the working end of the hydraulic buffer 16 faces the outer surface of the rotating frame 6. When the V-shaped outer wall of the rotating frame 6 contacts the buffer 16, it is used to play a certain buffering role on the rotating frame 6 to prevent the rotating frame 6 from stopping suddenly and causing the upper cylinder head to shake (because the cylinder head is simply placed on the support plate 13 and is not pressed, the buffer 16 can play a buffering effect); more specifically, in this example, the first sensor 17 is a proximity switch, which is used to monitor whether the V-shaped rotating frame 6 is rotated into place. When the rotating frame 6 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, and the robot then performs the next action.

[0039] A second sensor 15 for monitoring the position of the cylinder head is installed above the support plate 13. In this example, the second sensor 15 is an infrared transmitter and an infrared receiver, which are arranged at the upper edge positions of the two support plates 13 and facing each other. When the cylinder head is placed on the support plate 13, the signal emitted by the infrared transmitter is blocked by the cylinder head, and thus a signal instruction can be sent to the robot's control system.

[0040] When this rotating device for the cylinder head is in use, it is placed between two processing steps of the cylinder head. When the robot takes the cylinder head out from the processing station of the previous process, the cylinder head can be placed on the support plate 13 first. During the placement process, the positioning pin 14 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 15 sends an instruction to the robot control system, so that the cylinder 4 starts, and the telescopic cylinder of the cylinder 4 extends forward to drive the rotating frame 6, the rotating shaft 11, the rotating frame 12, the support plate 13 and the cylinder head to rotate synchronously. When rotated to the specified position, the buffer 16 can contact the rotating frame 6 to achieve a buffering effect, and the first sensor 17 can monitor the position of the rotating frame 6, thereby sending a signal to the robot control system. At this time, the robot grabs the cylinder head that has been rotated on the support plate 13 and places it in the processing station of the next process to complete the entire rotation work.

[0041] 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.
