Inaccurate timing can lead to reduced engine performance, reduced fuel efficiency, and even damage to the engine.

[0003] An automotive engine timing zero-point correction tool is a specialized device used to adjust the engine's timing system, ensuring the crankshaft and camshaft positions are aligned with the manufacturer's specified reference points. This tool secures the camshaft, crankshaft, or other related components to prevent them from moving during adjustment, allowing for precise alignment of the timing belt or chain. It's ideal for replacing timing belts, correcting timing deviations, or maintaining engine performance. It helps synchronize the opening and closing of engine valves with piston movement, ensuring efficient engine operation and preventing mechanical failures.

[0033] 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.

[0034] Reference Figure 1 、 Figure 3 、 Figure 4 The utility model provides an embodiment: a tool for correcting the zero point timing of an automobile engine, comprising two cross bars 1, fixed shafts 2 being installed at opposite ends of the two cross bars 1, the cross bars 1 being used to connect the fixed shafts 2 to provide stability for the fixed shafts 2, and the fixed shafts 2 being used to lock the cam, a connecting mechanism 3 being provided at the opposite ends of the two cross bars 1, an extension rod 5 being installed at the top of the connecting mechanism 3, an anti-skid pad 6 being provided on the outer periphery of the extension rod 5, the extension rod 5 being used to facilitate the use of the tool by the staff, the anti-skid pad 6 being used to provide anti-skid ability to prevent the extension rod 5 from falling out of the hands of the staff when in use, and fixing mechanisms 7 being provided on the left and right sides of the top of the connecting mechanism 3;

[0035] The two fixing mechanisms 7 each include a dial plate 701, which is slidably connected to the left and right sides of the top of the connecting mechanism 3. The two dial plates 701 are fixedly connected to a connecting rod 702 on the opposite side of each other. The dial plate 701 is connected to the connecting rod 702. When the dial plate 701 is moved, the connecting rod 702 is driven to move together. The opposite sides of the two fixing mechanisms 7 are fixedly connected to a partition plate 704. The opposite sides of the two connecting rods 702 are fixedly connected to a card block 703. The card block 703 is connected to the connecting rod 702 and is mainly used to transmit motion. When the connecting rod 702 is driven by the dial plate 701, the card block 703 is connected to the connecting rod 702. When moving, the block 703 will be driven to move together. The outer periphery of the two connecting rods 702 is provided with a support component 8. The left and right ends of the extension rod 5 close to the connecting mechanism 3 are provided with a slot 706. The block 703 is slidably connected to the inside of the slot 706. The slot 706 is used in conjunction with the block 703. By sliding the block 703 into the slot 706, the block 703 can provide a limiting and fixing effect on the extension rod 5. The left and right sides of the top of the connecting mechanism 3 are provided with a slide groove 705. The partition 704 is slidably connected to the inside of the slide groove 705. The slide groove 705 is used to accommodate the partition 704.

[0036] Reference Figure 1 - Figure 2The connecting mechanism 3 includes a connecting block 301, which is slidably connected to the opposite ends of the two cross bars 1. The opposite sides of the two cross bars 1 are fixedly connected with connecting plates 302. The front and rear sides of the connecting block 301 are provided with fixing components 4. The connecting plate 302 is connected to the cross bar 1. When the cross bar 1 moves, the connecting plate 302 will be driven to move together. The connecting block 301 is used to accommodate the connecting plate 302 and can also be adapted to other tools.

[0037] Reference Figure 4 The support assembly 8 includes a limit plate 802, which is fixedly connected to the outer periphery of the connecting rod 702. A spring 801 is fixedly connected to the side of the limit plate 802 away from the block 703. One end of the spring 801 away from the limit plate 802 is fixedly connected to the inside of the connecting block 301. The limit plate 802 is connected to the connecting rod 702. When the connecting rod 702 moves, the limit plate 802 is driven to move together, and the spring 801 is installed inside the connecting block 301. When the limit plate 802 moves, pressure is applied to the spring 801, thereby squeezing the spring 801. The spring 801 is made of 65Mn spring steel.

[0038] Reference Figure 5 The fixing assembly 4 includes a locking bolt 401, which is threadedly connected to the outer periphery of the connecting block 301. A gasket 402 is slidably connected to the outer periphery of the locking bolt 401. One end of the locking bolt 401 close to the connecting block 301 is threadedly connected to the inside of the connecting plate 302, and the side of the gasket 402 away from the locking bolt 401 is slidably connected to the outer periphery of the connecting block 301. The locking bolt 401 is used to be threadedly connected to the connecting plate 302 so that the connecting plate 302 is installed in the connecting block 301. The gasket 402 is used to disperse the pressure on the end of the bolt.

[0039] Working principle: When correcting the timing zero point of the engine, when the cam needs to be fixed, the two fixed shafts 2 need to be aligned with the cam to lock the cam to prevent it from rotating. When the cam spacing is too long, the distance between the two cross bars 1 needs to be adjusted, and the two locking bolts 401 are rotated respectively to make the two locking bolts 401 unscrewed from the two connecting plates 302 respectively, and then the two cross bars 1 are moved. When the two cross bars 1 move, the two connecting plates 302 will also move accordingly in the connecting block 301. Bolt holes are pre-opened in the connecting plate 302, so that the corresponding position of the connecting plate 302 can be selected according to the position of the bolt hole. By screwing the locking bolt 401 into the connecting plate 302 again, the position of the connecting plate 302 can be fixed, thereby adjusting the position of the two cross bars 1 to match the cam position.

[0040] Then, when the fixed shaft 2 is inconvenient to contact with the cam, the extension rod 5 needs to be installed. By toggling the dial plate 701, the dial plate 701 drives the connecting rod 702 to move. When the connecting rod 702 moves, the block 703 is driven to move together, so that the block 703 slides into the interior of the connecting block 301. When the connecting rod 702 moves, the limit plate 802 connected to the outer periphery of the connecting rod 702 moves with the connecting rod 702 and squeezes the spring 801, and then the bottom of the extension rod 5 is moved. When the locking block 703 is inserted into the connecting block 301 so that the locking block 703 can cooperate with the locking groove 706, the dial plate 701 can be released. When the dial plate 701 is released, the spring 801 will lose the squeezing of the limit plate 802, and then the spring 801 will generate a reset movement to push the limit plate 802 to move. When the limit plate 802 moves, the locking block 703 will be driven to move, so that the locking block 703 slides into the locking groove 706, and the extension rod 5 and the connecting block 301 are installed, which is convenient for the staff to use.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. 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.
