Description

Technical Field

[0001] This utility model belongs to the field of engine assembly, and in particular relates to a positioning and assembly device for automobile engine cylinder block and cylinder head. Background Technology

[0002] With the development of the automotive industry, the assembly process of engine housings requires a higher level of automation and intelligence. Traditional manual assembly methods can no longer meet the needs of modern automobile production, thus requiring the use of automated equipment and technologies to achieve efficient and high-precision assembly. However, even after the internal parts of the engine housing are successfully assembled, operators still need to use a hand-held screwdriver to tighten the screws on the engine housing.

[0003] Because the bottom of the engine cylinder is uneven, the engine cylinder will tilt when placed, which will affect the installation of the cylinder head. In addition, the cylinder head installation lacks a pre-fixing device, which makes it easy for the cylinder head to shift during installation, requiring multiple people to work together. Utility Model Content

[0004] This utility model provides a positioning and assembly device for automobile engine cylinder block and cylinder head, which aims to solve the problems of uneven bottom of existing engine cylinders, which causes the engine cylinders to tilt when placed, thus affecting the installation of cylinder heads, and the lack of pre-fixing devices for cylinder head installation, which makes the cylinder head easy to shift during installation and requires multiple people to work together.

[0005] This utility model is implemented as follows: a positioning and assembly device for an automobile engine cylinder block and cylinder head includes a base plate, a controller, a booster pump, and a support column. The base plate has an internal cavity, and the booster pump and the support column are connected to the internal cavity. The support column includes a sleeve, and a push rod is movably connected to the upper surface of the sleeve. A piston plate that fits against the inner wall of the sleeve is fixedly connected to the lower surface of the push rod. An electric slide rail is fixedly connected to the upper surface of the base plate. An electric hydraulic rod is fixedly connected to the outer wall of the moving end of the electric slide rail, and a protruding plate is fixedly connected to the telescopic end of the electric hydraulic rod. The electric slide rail, the electric hydraulic rod, the booster pump, and the controller are electrically connected.

[0006] Preferably, a pressure sensor is fixedly connected to the inner wall of the cavity, and the pressure sensor is electrically connected to the controller.

[0007] Preferably, a limiting block is slidably connected to the outer wall of the convex plate, and a bolt is threadedly connected to the outer wall of the convex plate, wherein the bolt and the limiting block are rotatably connected.

[0008] Preferably, a weight sensor is provided between the convex plate and the electro-hydraulic rod, and the weight sensor is electrically connected to the controller.

[0009] Preferably, the outer wall of the booster pump is threaded with a dust cover.

[0010] Preferably, the outer wall of the dust cover is provided with anti-slip texture.

[0011] Compared with the prior art, the embodiments of this application have the following main advantages:

[0012] By operating the booster air pump, the air pressure inside the cavity and support columns increases, causing the push rod to push out onto the sleeve. The car engine cylinder block is then placed on the support columns, which support the cylinder block. The weight of the cylinder block causes the push rod below it to retract into the sleeve. The air pressure inside the cavity and support columns is equal everywhere, ensuring the cylinder block is placed stably on top of the base plate and preventing tilting. By moving the electric slide rail, the protruding plate can be moved to the outside of the cylinder block. By retracting the electric hydraulic rod, the protruding plate can be lowered, thus pressing and limiting the cylinder head onto the cylinder block. This prevents the cylinder head from shifting during installation, facilitating the assembly of the car engine cylinder block and cylinder head and improving assembly efficiency.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model provides a positioning and assembly device for an automobile engine cylinder block and cylinder head, such as... Figure 1-4 As shown, the system includes a base plate 1, a controller 2, a booster air pump 3, and a support column 5. The base plate 1 has an inner cavity 6, which is connected to the booster air pump 3 and the support column 5. The support column 5 includes a sleeve 501, and a push rod 502 is movably connected to the upper surface of the sleeve 501. A piston plate 503 that fits against the inner wall of the sleeve 501 is fixedly connected to the lower surface of the push rod 502. An electric slide rail 8 is fixedly connected to the upper surface of the base plate 1. An electric hydraulic rod 9 is fixedly connected to the outer wall of the moving end of the electric slide rail 8, and a protruding plate 10 is fixedly connected to the telescopic end of the electric hydraulic rod 9. The electric slide rail 8, the electric hydraulic rod 9, the booster air pump 3, and the controller 2 are electrically connected.

[0021] It should be noted that the uneven bottom of the existing engine cylinders causes them to tilt during placement, affecting cylinder head installation. Furthermore, the cylinder head installation lacks a pre-fixing device, making it prone to misalignment and requiring multiple operators. Therefore, to address these issues—namely, the uneven bottom of the existing engine cylinders causing tilting during placement and affecting cylinder head installation, and the lack of a pre-fixing device leading to misalignment and requiring multiple operators—this solution utilizes a booster air pump 3 to increase the air pressure within the inner cavity 6 and support column 5, thereby pushing the push rod 502 against the sleeve 501. The engine block is placed on the support column 5. The cylinder block is supported by multiple support columns 5. The weight of the cylinder block will cause the push rod 502 below the cylinder block to retract into the sleeve 501. The air pressure in the inner cavity 6 and the support column 5 is equal everywhere, so that the cylinder block is placed stably on the base plate 1, preventing the cylinder block from tilting. By moving the moving end of the electric slide rail 8, the convex plate 10 can be moved to the outside of the cylinder block. By contracting the telescopic end of the electric hydraulic rod 9, the convex plate 10 can be lowered, thereby squeezing and limiting the cylinder head on the cylinder block, preventing the cylinder head from shifting during installation, facilitating the assembly of the engine block and cylinder head, and improving the assembly efficiency.

[0022] In a further preferred embodiment of this utility model, such as Figure 3 As shown, a pressure sensor 7 is fixedly connected to the inner wall of the inner cavity 6, and the pressure sensor 7 is electrically connected to the controller 2.

[0023] In this embodiment, the air pressure in the inner cavity 6 is detected by the air pressure sensor 7. When the air pressure in the inner cavity 6 exceeds the set value, the air pressure sensor 7 sends a signal to the controller 2. The controller 2 receives the signal from the air pressure sensor 7 and controls the booster air pump 3 to work, so that the air pressure in the inner cavity 6 is within a safe range, ensuring the normal operation of the equipment.

[0024] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the outer wall of the protruding plate 10 is slidably connected to the limiting block 11, and the outer wall of the protruding plate 10 is threadedly connected to the bolt 12, and the bolt 12 and the limiting block 11 are rotatably connected.

[0025] In this embodiment, by rotating the bolt 12, the protrusion distance of the adjusting limit block 11 can be adjusted, thereby adjusting the protrusion length of the protrusion plate 10 and improving the working range of the protrusion plate 10.

[0026] In a further preferred embodiment of this utility model, such as Figure 1 As shown, a weight sensor is installed between the convex plate 10 and the electro-hydraulic rod 9, and the weight sensor is electrically connected to the controller 2.

[0027] In this embodiment, the pressure between the convex plate 10 and the engine cylinder is detected by a weight sensor. When the pressure between the convex plate 10 and the engine cylinder reaches a set value, the weight sensor sends a signal to the controller 2. The controller 2 receives the signal from the weight sensor and controls the electric hydraulic rod 9 to stop working, thus preventing excessive pressure between the convex plate 10 and the engine cylinder from causing damage to the equipment or the engine cylinder.

[0028] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the outer wall of the booster air pump 3 is threaded with a dust cover 4.

[0029] In this embodiment, the dust cover 4 prevents external impurities from entering the inner cavity 6 through the booster air pump 3.

[0030] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the outer wall of the dust cover 4 is provided with anti-slip texture.

[0031] In this embodiment, the anti-slip texture increases the friction of the outer wall of the dust cover 4, preventing slippage when personnel rotate the dust cover 4.
