[0002] In the field of diesel engine manufacturing, the cylinder head is a key component of the entire diesel engine. In the cylinder head processing process, cleaning the cylinder head is an important way to ensure cleanliness, which affects the durability and reliability of the cylinder head and ultimately affects the service life of the engine. Correspondingly, the drying process coordinated with the cleaning process also affects the cleanliness index. Drying the cylinder head can not only reduce the dust enrichment on the surface of the cylinder head during the manufacturing process, but also avoid iron chips adhesion.

[0004] However, this method is prone to generate dust during the drying process of the cylinder head, resulting in increased pollution. In addition, due to the complex structure of the cylinder head, this method has a poor effect on the internal drying of the cylinder head. At the same time, this method produces a lot of noise during the drying process of the cylinder head, affecting the working environment and the health of the operator. Utility Model Content

[0007] A cylinder head vacuum drying device comprises a drying chamber for accommodating the cylinder head, the drying chamber comprising an upper chamber connected to a lifting drive mechanism and a lower chamber connected to a vacuum pump, the lifting drive mechanism drives the upper chamber to move vertically to enclose or separate from the lower chamber, and the lower chamber is provided with an air hole connected to the vacuum pump.

[0008] In a preferred implementation of a cylinder head vacuum drying device, the vacuum drying device includes a limiting track arranged on the lower cavity, the cylinder head moves along the limiting track to a stop position, and at the same time the lifting drive mechanism drives the upper cavity to move to enclose the lower cavity.

[0009] In a preferred implementation of a cylinder head vacuum drying device, the limiting track includes a rotating rod drivingly connected to the output shaft of the motor, rollers are provided at both ends of the rotating rod, the rotating rod drives the rollers to rotate, and the cylinder head moves along the rollers.

[0010] In a preferred implementation of a cylinder head vacuum drying device, along the advancing direction of the cylinder head, a rotating rod located at the front end of the stop position is provided with a stop block. The stop block rotates with the rotating rod, and when the cylinder head is in the stop position, the stop block is vertically upward.

[0011] In a preferred implementation of a cylinder head vacuum drying device, guide rails are respectively provided on both sides of the limit rail along the advancing direction of the cylinder head, and the two guide rails move horizontally respectively to adjust the distance between the two guide rails.

[0012] In a preferred implementation of a cylinder head vacuum drying device, the lower cavity is provided with a plurality of installation positions for fixing the guide rails, and the guide rails are fixed at different installation positions to adjust the distance between the two guide rails.

[0013] In a preferred implementation of a cylinder head vacuum drying device, the lower cavity is provided with position sensors, which are respectively arranged on both sides of the limit rail to sense the position of the cylinder head on the limit rail.

[0014] In a preferred implementation of a cylinder head vacuum drying device, the lifting drive mechanism includes a drive cylinder and moving guide rails located on both sides of the drive cylinder. The drive cylinder and the moving guide rails are fixed to the same connecting plate, and the drive cylinder and the moving guide rails are arranged in parallel.

[0015] In a preferred implementation of a cylinder head vacuum drying device, a first seal is provided on the bottom surface of the upper cavity, and a second seal is provided on the top surface of the lower cavity. The first seal and the second seal are arranged in alignment.

[0016] In a preferred implementation of a cylinder head vacuum drying device, the first seal and the second seal are sealing gaskets arranged opposite to each other.

[0017] Due to the adoption of the above technical solutions, the beneficial effects obtained by this application are as follows:

[0018] (1) In this solution, a drying chamber is set to provide a separate drying space for the cylinder head, and a vacuum pump is used to achieve suction dehumidification inside the drying chamber. When the upper cavity and the lower cavity are separated, the cylinder head moves along the production line roller path to the position of the drying device, and the upper cavity and the lower cavity enclose to provide a closed drying space for the cylinder head, thereby avoiding dust pollution during the drying process, and the outer wall of the drying chamber realizes the isolation between the cylinder head and the outside world, which is beneficial to reducing noise. The vacuum pump is connected to the lower cavity, and the drying chamber is sucked through the vacuum pump, and the cylinder head located in the drying chamber is vacuum-dried in this way, which is beneficial to achieving a good drying effect inside the cylinder head.

[0019] (2) The cylinder head moves along a preset path to the limiting track and then moves along the limiting track to the stop position. At this time, the lifting drive mechanism drives the upper cavity to move downward to enclose with the lower cavity, thereby forming a drying cavity to perform vacuum drying on the cylinder head located at the stop position. After drying is completed, the lifting drive mechanism drives the upper cavity to move upward, enabling the cylinder head to continue moving along the limiting track to leave the vacuum drying device for subsequent processing. The drying efficiency of the cylinder head is high and the drying effect is good.

[0020] (3) A stop block is set at the front end of the stop position. Since the cylinder head moves along the roller, when the rotating rod and the roller stop rotating, the cylinder head still has a tendency to move forward at the moment of stopping. By setting the stop block to block the cylinder head, and at the same time, after the cylinder head touches the stop block, the stop block has a resilient force on the cylinder head, causing the cylinder head to slightly retreat, ensuring that the cylinder head is limited at the stop position, which is beneficial to achieving a stable and efficient drying effect on the cylinder head.

[0021] (4) A guiding track is set. When the cylinder head moves on the limiting track, the guiding track guides the cylinder head. The cylinder head is located between two guiding tracks. When the cylinder head moves along the limiting track, the guiding track limits and guides it from both sides of the moving direction of the cylinder head, preventing the cylinder head from shifting during the moving process, so that the cylinder head moves stably along the limiting track.

[0022] (5) The upper cavity and the lower cavity are respectively provided with a first sealing member and a second sealing member. When the upper cavity and the lower cavity enclose, the first sealing member and the second sealing member achieve a sealing effect on the formed drying cavity, thereby providing a sealed environment for the suction work of the vacuum pump, which is beneficial to enhancing the drying efficiency and drying effect of the vacuum drying device on the cylinder head.

[0031] In the following description, many specific details are set forth in order to fully understand the present application.

In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0035] The solution of this application provides a cylinder head vacuum drying device, as Figures 1 to 4 shown, which includes a drying chamber for accommodating the cylinder head 12. The drying chamber includes an upper chamber 1 connected to a lifting drive mechanism and a lower chamber 2 connected to a vacuum pump 11. The lifting drive mechanism drives the upper chamber 1 to telescopically move vertically to enclose or separate from the lower chamber 2. The lower chamber 2 is provided with air holes communicating with the vacuum pump 11.

[0036] This solution provides a separate drying space for the cylinder head 12 by setting up the drying chamber, and uses the vacuum pump 11 to achieve suction and dehumidification inside the drying chamber. When the upper chamber 1 and the lower chamber 2 are separated, the cylinder head 12 moves along its production line roller path to the position of the drying device, and the upper chamber 1 and the lower chamber 2 enclose to provide a closed drying space for the cylinder head 12, thereby avoiding dust pollution during the drying process, and the outer wall of the drying chamber isolates the cylinder head 12 from the outside, which is beneficial to reducing noise. The vacuum pump 11 is connected to the lower chamber 2. The vacuum pump 11 is connected to the lower chamber 2 through the air holes, and sucks the drying chamber through the air holes, and vacuum-dries the cylinder head 12 located in the drying chamber in this way, which is beneficial to achieving a good drying effect inside the cylinder head 12.

[0037] It should be noted that the cylinder head 12 vacuum drying device of the solution of this application can be combined and applied to the production line roller path, and the cylinder head 12 moves along the production line roller path to the drying chamber to achieve vacuum drying inside the drying chamber.

[0038] In one embodiment, as Figure 2 、 Figure 4 shown, the vacuum drying device includes a limit track 3 provided in the lower chamber 2. The cylinder head 12 moves along the limit track 3 to the stop position, and at the same time, the lifting drive mechanism drives the upper chamber 1 to move to enclose the lower chamber 2.

[0039] It can be understood that the upper cavity 1 is hollow inside to provide a placement space for the cylinder head 12 after the upper cavity 1 is closed, and the lower cavity 2 is provided with a limiting track 3 inside to limit the cylinder head 12, so as to vacuum dry the cylinder head 12 when the upper cavity 1 and the lower cavity 2 are closed. The stop position described in this solution can determine its position and range according to the actual application scenario to ensure that the cylinder head 12 is located in the drying chamber when the upper cavity 1 and the lower cavity 2 are closed.

[0040] The cylinder head 12 moves along the preset path to the limit track 3, and moves along the limit track 3 to the stop position. At this time, the lifting drive mechanism drives the upper cavity 1 to move downward to enclose the lower cavity 2, thereby forming a drying chamber to vacuum dry the cylinder head 12 at the stop position. After drying is completed, the lifting drive mechanism drives the upper cavity 1 to move upward, so that the cylinder head 12 can continue to move along the limit track 3 to leave the vacuum drying device for subsequent processing. The cylinder head 12 has high drying efficiency and good drying effect.

[0041] Furthermore, the limiting track 3 includes a rotating rod 31 drivingly connected to the output shaft of the motor 10 , and rollers 32 are provided at both ends of the rotating rod 31 . The rotating rod 31 drives the rollers 32 to rotate, and the cylinder head 12 moves along the rollers 32 .

[0042] In one embodiment, Figure 2 As shown, along the moving direction of the cylinder head 12, the rotating rod 31 located at the front end of the stop position is provided with a stop block 4, the stop block 4 rotates with the rotating rod 31, and when the cylinder head 12 is located at the stop position, the stop block 4 is vertically upward.

[0043] The stop block 4 is arranged so as to be located at the front end of the stop position. Since the cylinder head 12 moves along the roller 32, when the rotating rod 31 and the roller 32 stop rotating, the cylinder head 12 still has a tendency to move forward at the moment of stopping. The cylinder head 12 is blocked by the stop block 4. At the same time, after the cylinder head 12 touches the stop block 4, the stop block 4 has a rebound force on the cylinder head 12, so that the cylinder head 12 slightly retreats, ensuring that the cylinder head 12 is limited at the stop position, which is beneficial to achieving a stable and efficient drying effect for the cylinder head 12.

[0044] Preferably, guide rails 5 are respectively provided on both sides of the limiting rail 3 along the travel direction of the cylinder head 12 , and the two guide rails 5 are respectively moved in the horizontal direction to adjust the distance between the two guide rails 5 .

[0045] A guiding track 5 is provided. When the cylinder head 12 moves along the limiting track 3, the guiding track 5 guides the cylinder head 12. The cylinder head 12 is located between two guiding tracks 5. When the cylinder head 12 moves along the limiting track 3, the guiding track 5 limits and guides the cylinder head 12 from both sides of the moving direction of the cylinder head 12, preventing the cylinder head 12 from shifting during movement, so that the cylinder head 12 moves stably along the limiting track 3.

[0046] In one embodiment, the lower cavity 2 is provided with a plurality of mounting positions for fixing the guiding track 5, and the guiding track 5 is fixed at different mounting positions to adjust the distance between the two guiding tracks 5.

[0047] By adjusting the distance between the two guiding tracks 5, the drying device can be adapted to cylinder heads 12 of different specifications. In the actual production process, the production line usually processes cylinder heads 12 of the same specification for a long time. Therefore, after determining the distance between the two guiding tracks 5, it is not necessary to adjust it frequently. The fixed connection method of the guiding track 5 at the mounting position can also be various. For example, bolts and other fasteners can be used to position it.

[0048] Specifically, in this embodiment, the top wall of the lower cavity 2 is provided with a mounting seat 51. The mounting seat 51 is provided with a plurality of positioning holes to form a plurality of mounting positions. The guiding track 5 includes a positioning block 52 connected to the mounting seat 51 through the positioning holes and a guide rod 53 connected to the positioning block 52. The guide rod 53 is arranged along the moving direction of the cylinder head 12. As the connection at different positioning holes changes, the radial position of the guide rod 53 changes, thereby adjusting the distance between two relatively arranged guide rods 53 to adapt to cylinder heads 12 of different specifications.

[0049] In addition, in addition to providing a plurality of mounting positions, the position of the guiding track 5 can also be adjusted by other means in the prior art. For example, an adjusting handle is provided to connect with the guide rod 53 instead of the positioning block 52. Rotating the adjusting handle drives the guide rod 53 to move. This method can be achieved by the prior art and will not be elaborated here.

[0050] In one embodiment, as Figure 2 shown, the lower cavity 2 is provided with a position sensor 6. The position sensors 6 are respectively arranged on both sides of the limiting track 3 to sense the position of the cylinder head 12 on the limiting track 3.

[0051] The position sensor 6 is provided to monitor the entry and exit of the cylinder head 12 in the lower cavity 2.

[0052] It should be noted that the vacuum drying device in the solution of this application is connected to a PLC control system. When the position sensor 6 detects the entry of the cylinder head 12, it sends a signal to the PLC control system, and then the control system sends a signal to make the driving cylinder 7 move, thereby realizing the sealed vacuum drying of the cylinder head 12.

[0053] In one embodiment, as Figure 1 , Figure 3 shown, the lifting drive mechanism includes a drive cylinder 7 and moving guide rails 8 on both sides of the drive cylinder 7. The drive cylinder 7 and the moving guide rails 8 are fixed to the same connecting plate 9, and the drive cylinder 7 and the moving guide rails 8 are arranged in parallel.

[0054] The drive cylinder 7 and the moving guide rails 8 are respectively connected to the upper cavity 1 through the connecting plate 9. The telescopic movement of the drive cylinder 7 drives the upper cavity 1 to extend or retract, realizing the lifting movement of the upper cavity 1, so as to realize the enclosure or separation of the upper cavity 1 and the lower cavity 2. When the drive cylinder 7 drives the upper cavity 1 to perform telescopic movement in the vertical direction, the moving guide rails 8 provide vertical guidance for its telescopic movement to avoid deviation. It should be noted here that the arrangement form of the moving guide rails 8 can adopt a sleeve form to realize synchronous telescopic movement. The drive cylinder 7 and the moving guide rails 8 are fixed through the connecting plate 9 at the same time, strengthening the support strength, and combined with its fixation on the top of the upper cavity 1, the drive cylinder 7 and the upper cavity 1 always remain stable during the telescopic movement process.

[0055] In one embodiment, a first sealing member is provided on the bottom surface of the upper cavity 1, and a second sealing member is provided on the top surface of the lower cavity 2. The first sealing member and the second sealing member are arranged in alignment.

[0056] The upper cavity 1 and the lower cavity 2 are respectively provided with a first sealing member and a second sealing member. When the upper cavity 1 and the lower cavity 2 are enclosed, the first sealing member and the second sealing member form a sealing effect on the enclosed drying cavity, thereby providing a sealed environment for the pumping work of the vacuum pump 11, which is beneficial to enhancing the drying efficiency and drying effect of the vacuum drying device on the cylinder head 12.

[0057] Preferably, as Figure 1 , Figure 3 shown, the first sealing member and the second sealing member are sealing gaskets 13 arranged opposite to each other.

[0058] The sealing gasket 13 is made of a flexible material, providing collision buffering when the upper cavity 1 and the lower cavity 2 are enclosed, and reducing collision noise. At the same time, the sealing gasket 13 realizes circumferential sealing of the drying cavity, which is convenient for better realizing the vacuum drying effect.

[0059] In addition, the first sealing member and the second sealing member can also be sealed in other forms. For example, one of the first sealing member and the second sealing member is provided with a limit groove, and the other is provided with a limit protrusion adapted to the limit groove, and the two cooperate to realize the sealed connection of the upper cavity 1 and the lower cavity 2.

[0060] What is not described in this application can be realized by adopting or referring to the existing technology.

[0061] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other, and the key point of each embodiment is to illustrate the differences from other embodiments.

[0062] The above description is only for the embodiments of the present application and is not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
