[0015] 1. This utility model provides a testing device for motorcycle cylinder block processing. It adopts the cooperation between a testing bracket, a lifting mechanism, an L-shaped plate, a clamping mechanism, and a moving groove. By placing the motorcycle cylinder block on the testing table, the clamping mechanisms on both sides are operated to move the motorcycle cylinder block closer together. According to the size of the motorcycle cylinder block, the testing table is driven to move up and down by a hydraulic cylinder, which makes it easy to clamp and fix the clamping plate to the surface of the cylinder block. This avoids loosening or displacement during testing. It solves the problem that existing testing devices mostly rely on manual clamping and positioning for leak detection, which is inconvenient to operate and prone to loosening or displacement during testing.

The connecting sleeve is then inserted into the outside of the connecting pipe, and the sealing ring fits tightly against the outer wall of the connecting pipe, ensuring a tight seal. This solves the problem that injecting gas into the cylinder through an air pipe, but with different diameters of connecting pipes on different cylinder sizes, makes it difficult to seal the connecting end of the air pipe for connecting pipes on different sizes of cylinders, reducing the practicality of the device. This device achieves the beneficial effect of facilitating the sealing connection of connecting pipes on cylinders of different sizes. Attached Figure Description

[0025] The system includes a lifting mechanism 2, an L-shaped plate 3, a clamping mechanism 4, a vertical plate 6, a connecting port 7, and an air supply mechanism 8. Through the coordinated operation of the lifting mechanism 2 and the clamping mechanism 4, the system can clamp and fix motorcycle cylinders of different sizes, enhancing the stability of the clamping. By connecting the air supply mechanism 8 to the pipe on the motorcycle cylinder, air is supplied to the motorcycle cylinder through the air supply mechanism 8, thereby testing the airtightness of the motorcycle cylinder.

[0026] like Figure 2As shown, this utility model provides a technical solution for a testing device for motorcycle cylinder block processing: the lifting mechanism 2 includes a hydraulic cylinder 21, a testing platform 22, two fixed pipes 23, and two support rods 24. The output end of the hydraulic cylinder 21 is fixedly connected to the middle side of the bottom of the testing platform 22.

The outer wall of the limiting slider 49 is slidably connected to the inner wall of the limiting groove 301. The limiting slider 49 slides in the limiting groove 301, which plays the role of limiting the movement trajectory of the connecting plate 46.

[0028] like Figure 4As shown, this utility model provides a technical solution for a testing device for motorcycle cylinder block processing: the air supply mechanism 8 includes an air supply hose 81, a connector 82, a connecting pipe 83, a pressure gauge 84, a mounting component 85, and a connecting component 86. The lower end of the air supply hose 81 is fixedly connected to the middle of the connector 82. One end of the mounting component 85 is located at the upper end of the air supply hose 81. One end of the pressure gauge 84 is fixedly connected to the outer wall of the air supply hose 81 near the mounting component 85. The connection port of the connecting pipe 83 is fixedly connected to the connection end of the pressure gauge 84. By setting the air supply hose 81, the air supply hose 81 is connected to an air filling device through the connector 82 to perform air permeability testing on the motorcycle cylinder block.

[0029] like Figure 5 As shown, this utility model provides a technical solution for a testing device for motorcycle cylinder block machining: The mounting assembly 85 includes a positioning ring 851 and an external threaded tube 852. The upper end of the air supply hose 81 is fixedly connected to the middle of the positioning ring 851, and the rear end of the external threaded tube 852 is fixedly connected to the front end of the positioning ring 851. The air supply hose 81, the positioning ring 851, and the external threaded tube 852 are interconnected. The connecting assembly 86 includes a connecting sleeve 861, an internal threaded tube 862, and a sealing ring 863. The rear end of the connecting sleeve 861... The end is fixedly connected to the front end of the internal threaded tube 862, and the outer wall of the sealing ring 863 is fixedly connected to the inner wall of the connecting sleeve 861. The connecting sleeve 861 and the internal threaded tube 862 are interconnected. The inner wall of the internal threaded tube 862 is threadedly connected to the outer wall of the external threaded tube 852. The internal threaded tube 862 and the external threaded tube 852 are screwed together. In actual use, the motorcycle cylinder body and the air supply hose 81 are connected by selecting a matching connecting component 86 according to the diameter of the connecting pipe of the motorcycle cylinder body.

[0030] The working principle of this testing device for motorcycle cylinder block processing will be explained in detail below.

[0031] like Figure 1-5As shown, when performing an airtightness test on a motorcycle cylinder block, firstly, the testing device is connected to an external power source via the control panel 9. The motorcycle cylinder block is placed on top of the testing platform 22. The control panel 9 is then activated to start the stepper motors 41 on both sides. The output shafts of the stepper motors 41 drive the lead screws 42 to rotate, causing the moving block 44 to move the connecting plate 46 via the extension block 45. This causes the clamping plates 48 on both sides to move closer together via the connecting rod 47. During this movement, the hydraulic cylinder 21 is activated according to the size of the motorcycle cylinder block. The output end of the hydraulic cylinder 21 drives the testing platform 22 to move up and down, making the motorcycle cylinder block on the testing platform 22 parallel to the clamping plates 48 on both sides. Thus, the clamping plates 48 on both sides clamp and fix the surface of the motorcycle cylinder block. Then, the input... The air hose 81 is connected to the inflation device via the connector 82. A matching connector 86 is selected based on the diameter of the motorcycle cylinder's connecting pipe. The connector 861 is screwed onto the outside of the external threaded pipe 852 via the internal threaded pipe 862. The connector 861 is then inserted along the outside of the connecting pipe, ensuring that the sealing ring 863 on the inner wall of the connector 861 is tightly fitted to the surface of the connecting pipe, guaranteeing a seal between the motorcycle cylinder's connecting pipe and the air hose 81. The inflation device is then turned on, and air is supplied to the motorcycle cylinder through the air hose 81. Once the air pressure in the motorcycle cylinder reaches a certain value, the inflation device is turned off. The air pressure value on the pressure gauge 84 is then observed. If the air pressure value remains unchanged, there is no air leakage in the motorcycle cylinder; if the air pressure value drops, there is air leakage in the motorcycle cylinder.

[0032] The specific types and structures of the hydraulic cylinder 21, stepper motor 41, control panel 9, and inflation device used are all existing products. The specific circuit connection structure and control relationship between the control panel 9 and the hydraulic cylinder 21 and stepper motor 41 are also existing technologies, and will not be elaborated on here.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
