Description

Technical Field

[0001] This utility model belongs to the field of automotive engine cylinder head processing technology, and in particular relates to a hole position calibration device for automotive engine cylinder heads. Background Technology

[0002] The cylinder head is mounted on top of the cylinder block, sealing the cylinder from above and forming the combustion chamber. It is constantly in contact with high-temperature, high-pressure combustion gases, and therefore bears significant thermal and mechanical loads.

Among them, utility model patent application number CN216503597U discloses a hole position calibration device for automotive engine cylinder head processing, relating to the field of automotive engine cylinder head technology. This hole position calibration device for automotive engine cylinder head processing has a punch fixedly connected to the upper surface of the worktable. Two fixing mechanisms are provided on the upper surface of the worktable, located on the side close to the guide plate and the fixing plate. A rotating block contacts the cylinder head. By adjusting the spacing of the cylinder head, a rotating screw rotates inside a limiting post to a suitable position and is fixed inside the limiting post by friction. Rotating the rotating block further fixes the cylinder head. Rotating the rotating block disengages the cylinder head, increasing the disassembly speed and work efficiency.

[0004] The drawback of the existing technology is that the cylinder head can only be limited in the horizontal direction during positioning. The vibration generated during processing can easily cause the cylinder head to collide with the support platform, resulting in damage and affecting the actual processing effect.

[0005] Based on this, the present invention designs a hole position calibration device for automobile engine cylinder head to solve the above problems. Utility Model Content

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0026] 1. In this utility model, by setting a buffer block, a two-way lead screw, a fixed block, a rotating rod, a limiting block, and a telescopic rod, when the two-way lead screw rotates, the two fixed blocks and the rotating rod can move relative to each other, so that the moving block drives the locking rod, the electric push rod, and the buffer plate to the appropriate position. This allows the device to buffer the cylinder head to be processed, and at the same time, it can limit the front and rear sides of the cylinder head through the two limiting blocks. This reduces the occurrence of damage caused by direct collision between the cylinder head and the support platform, and ensures the actual processing effect.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-5 First embodiment:

[0037] This utility model provides a technical solution:

[0038] A hole alignment device for an automobile engine cylinder head includes a worktable 1, with four limiting grooves 2 and two moving grooves 3 on the top of the worktable 1.

[0039] The buffer assembly includes a movable column 4 that is slidably connected through the worktable 1. A support block 5 is fixedly connected to the top of the movable column 4. A buffer spring 6 is fixedly connected to the top of the support block 5. A buffer block 7 is fixedly connected to the top of the buffer spring 6. A fixing spring 8 is fixedly connected to the bottom of the support block 5.

[0040] The limiting assembly includes a bidirectional lead screw 9 rotatably connected within the support block 5. The bidirectional lead screw 9 is externally threaded to two fixing blocks 10. Each fixing block 10 is hinged to a rotating rod 11 via a pin. Each rotating rod 11 is hinged to a limiting block 12 via a pin. Telescopic rods 13 are fixedly connected to the two adjacent sides of the two fixing blocks 10. The two adjacent ends of the two telescopic rods 13 are respectively fixedly connected to the front and rear sides of the support block 5.

[0041] The fixed spring 8 is sleeved on the outside of the moving column 4 and is fixedly connected to the top of the workbench 1. The top of the workbench 1 is equipped with a drilling device, and the bottom of the workbench 1 is equipped with four support legs.

[0042] By setting up a buffer block 7, a two-way lead screw 9, a fixed block 10, a rotating rod 11, a limiting block 12, and a telescopic rod 13, the device can buffer the cylinder head to be processed, and at the same time limit the front and rear sides of the cylinder head through the two limiting blocks 12. This reduces the occurrence of damage caused by direct collision between the cylinder head and the support platform, and ensures the actual processing effect.

[0043] Second embodiment:

[0044] Specifically, such as Figure 2-3As shown, a moving block 14 is slidably connected in the moving groove 3. A locking rod 15 is hinged to the moving block 14 via a pin. An electric push rod 16 is fixedly connected to the top of the locking rod 15. A buffer plate 17 is fixedly connected to the bottom of the electric push rod 16. A threaded rod 18 is threadedly connected inside the moving block 14. A connecting block 19 is sleeved on the threaded rod 18. The connecting block 19 is fixedly connected to the bottom of the workbench 1. A handle is provided at one end of the threaded rod 18, and a stop is provided at the other end of the threaded rod 18. The bottom of the limiting block 12 is slidably connected in the limiting groove 2.

[0045] By incorporating a locking rod 15, an electric push rod 16, a buffer plate 17, a threaded rod 18, and a connecting block 19, the device can limit the cylinder head in multiple directions, further ensuring the device's positioning effect on the cylinder head.

[0046] Working principle and usage: First, rotate the double-acting lead screw 9 and threaded rod 18 according to the size of the cylinder head to be processed. When the double-acting lead screw 9 rotates, it causes the two fixed blocks 10 and the rotating rod 11 to move relative to each other, and causes the telescopic rod 13 to be in a stretched state. When the threaded rod 18 rotates, it causes the moving block 14 to drive the locking rod 15, the electric push rod 16 and the buffer plate 17 to move to the appropriate position. When the cylinder head is placed on top of the buffer block 7, it compresses the buffer spring 6 downward, and causes the support block 5 and the moving column 4 to move downward within the worktable 1, thereby compressing the fixed spring 8. Under the action of the pin, the two rotating rods 11 rotate relative to each other and push the two limiting blocks 12 to limit the front and rear sides inside the cylinder head. When the cylinder head moves downward, it can press down on the two locking rods 15. Under the action of the pin, the two locking rods 15 rotate towards each other, thereby limiting the left and right sides outside the cylinder head. At the same time, the two electric push rods 16 are activated, which in turn allows the two buffer plates 17 to limit the top of the cylinder head.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
