Description

Technical Field

[0001] This utility model relates to the field of diesel engine assembly technology, specifically a cylinder head tray with safety protection. Background Technology

[0002] The cylinder head is one of the core functional components of marine diesel engines. Its design usually presents asymmetrical geometric features. Due to the complex features of valve seat bosses, cooling water channel interfaces and bolt mounting holes, the bottom surface has local slopes or stepped undulations, which causes its center of gravity to be skewed.

[0003] During diesel engine assembly, cylinder heads are typically supported and transported using pallets. Traditional pallets often employ a flat support structure, with the cylinder head placed directly on the pallet in an unprotected, tilted position. This can easily lead to multi-directional tilting and swaying during movement, and in extreme cases, the cylinder head may even fall off the pallet, posing a serious safety hazard. Furthermore, the tilted position of the upper machined surface of the cylinder head (i.e., the mounting surface that mates with the cylinder block) makes pre-processing operations (such as applying sealant or installing gaskets) inconvenient, thus affecting assembly efficiency.

[0004] Therefore, this utility model proposes a cylinder head tray with safety protection to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cylinder head tray with safety protection to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cylinder head tray with safety protection includes a tray body, on which a recessed groove adapted to the shape and contour of the cylinder head is provided for embedding the cylinder head and so that the upper machined surface of the cylinder head is in a horizontal upward state. The tray also includes a fastening component for fixing the embedded cylinder head.

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Please see Figure 1 A cylinder head tray with safety protection includes a tray body 2, on which a recessed groove 4 adapted to the shape and contour of the cylinder head is provided for embedding the cylinder head and so that the upper machined surface of the cylinder head is in a horizontal upward state. The tray also includes a fastening component 5 for fixing the embedded cylinder head.

[0026] The recessed groove 4 is adapted to the shape and contour of the cylinder head, allowing the cylinder head to be embedded in the disc 2. The upper machined surface of the cylinder head is horizontal and facing upwards, facilitating pre-processing operations. The bottom surface of the recessed groove 3 contacts and fits against the outer surface of the cylinder head. The embedded cylinder head is then fixed by the fastening component 5, thus providing full support and limiting the position of the cylinder head, providing good safety protection and ensuring the cylinder head remains stable during the movement of the tray, guaranteeing the safety of the cylinder head during transportation. It should be noted that the depth of the recessed groove 4 is such that after the cylinder head is embedded in the recessed groove 4, the upper edge of the cylinder head protrudes to a certain height outside the recessed groove 4, rather than being completely embedded in the recessed groove 4. This facilitates pre-processing operations on the upper machined surface of the cylinder head and the removal of the cylinder head.

[0027] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the disc body 2 is detachably provided with a support member 3, and the sinking groove 4 and the fastening component 5 are both provided on the support member 3;

[0028] The disc body 2 is provided with a mounting groove 6 that is adapted to the support member 3, and a number of fixing bolts 7 are provided on both sides of the mounting groove 6. The support member 3 is provided with bolt holes 9 that correspond one-to-one with and are adapted to the fixing bolts 7.

[0029] In this embodiment, multiple carriers 3 are provided with the same specifications. The recessed groove 4 provided on each carrier 3 has different specifications to accommodate cylinder heads of different specifications and shapes. In actual application, the corresponding carrier 3 is selected according to the specifications of the cylinder head to be transported. After the carrier 3 is placed in the placement groove 6, the fixing bolts 7 are rotated in sequence so that their threaded ends are screwed into the corresponding bolt holes 9 to fix the carrier 3.

[0030] Based on the previous embodiment, please refer to Figures 1-3 In one embodiment of this utility model, the fastening assembly 5 includes a plurality of mounting cavities 502 arranged on both sides of the sinking groove 4 (the specific number and the spacing between two vertically adjacent mounting cavities 502 are adaptively adjusted according to the specifications of the sinking groove 4). A first sealing piston 504 is provided in the mounting cavity 502. A connecting rod 503 is provided on the first sealing piston 504. An abutting block 505 for contacting and abutting with the cylinder head is provided at one end of the connecting rod 503 away from the first sealing piston 504. The fastening assembly 5 also includes a gas control component for injecting gas into the mounting cavity 502 and extracting gas from the mounting cavity 502 to achieve fastening and loosening of the cylinder head.

[0031] The air control component includes an air control chamber 506 disposed on the support member 3 and a second sealing piston 507 disposed in the air control chamber 506. The air control chamber 506 is connected to the mounting chamber 502 through an air guide channel 501. The upper part of the air control chamber 506 is provided with a cover 508 (used to seal the air control chamber 506 to prevent foreign objects from falling in). The cover 508 is provided with a vent hole 511 and a lead screw 509 is threaded through it. The lower end of the lead screw 509 is rotatably connected to the second sealing piston 507, and the upper end of the lead screw 509 is provided with a handwheel 510.

[0032] In this embodiment, after the cylinder head is placed in the sinking groove 3, the operator rotates the screw 509 downwards using the handwheel 510, which in turn moves the second sealing piston 507 downwards, injecting air into the mounting cavity 502. This causes the first sealing piston 504 to move towards the sinking groove 4 until the abutment block 505 abuts against the cylinder head (with appropriate abutment force), at which point the screw 509 is stopped. Thus, the cylinder head is firmly fixed. When the cylinder head needs to be removed, the screw 509 is rotated upwards using the handwheel 510, which in turn moves the second sealing piston 507 upwards, thereby extracting the gas from the mounting cavity 502. Under negative pressure, the second sealing piston 507 moves away from the sinking groove 4, causing the abutment block 505 to no longer abut against the cylinder head.

[0033] Please see Figure 1 and Figure 4 In one embodiment of the present invention, the tray further includes a base 1, the tray body 2 is rotatably mounted on the base 1, and a positioning component 8 for positioning the tray body 2 is provided between the base 1 and the tray body 2.

[0034] The positioning component 8 includes an annular brake pad 801 located at the bottom of the disc body 2 and coaxial with the rotation axis of the disc body 2, and at least one telescopic member 803 located on the base 1. The movable end of the telescopic member 803 is provided with a pressing member 802 for abutting against the annular brake pad 801 to achieve positioning of the disc body 2.

[0035] In this embodiment, during the cylinder head assembly process or when performing pre-processing operations on the upper surface of the cylinder head, the disc 2 can be rotated according to actual needs to adjust the cylinder head angle and orientation in the horizontal direction, thereby facilitating assembly or pre-processing operations. After the disc 2 is rotated into place, the telescopic member 803 extends, causing the pressing member 802 to abut tightly against the annular brake pad 801 (the friction coefficient between the pressing member 802 and the annular brake pad 801 is relatively large), thereby stopping and positioning the disc 2.

[0036] Furthermore, in this embodiment, the telescopic member 803 is an electric telescopic rod, and the base 1 is also provided with an operation panel 804 for controlling the extension and retraction of the telescopic member 803 and a power supply 805 for supplying power to the telescopic member 803, wherein the power supply 805 is a rechargeable battery.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
