DETAILED DESCRIPTION

[0016] The following will be described in detail in combination with the accompanying drawings Figs. 1-3 The application will be further described in detail.

[0017] The application embodiment discloses a bowl-shaped plug press-fitting device. Referring to Figs. 1-3 A bowl-shaped plug press-fitting device mainly consists of a rack 1, a press-fitting assembly 2, a workbench 3, a clamping assembly 4 and an air nozzle 5, realizes high-precision and high-efficiency press-fitting of the bowl-shaped plug, and ensures the press-fitting quality and sealing performance.

[0018] Referring to Fig. 1 The rack 1 is the basic support structure of the entire press-fitting device and is welded from high-strength cast iron or steel. The surface of the rack 1 is subjected to rust-proof treatment, such as paint spraying or galvanizing, to prolong the service life, reduce the equipment maintenance cost and ensure long-term stable use.

[0019] With reference to Fig. 3 , the press-fitting assembly 2 is mounted on the rack 1, including a telescopic cylinder 201, a connecting piece 202, a detection unit 203, and a press-fitting head 204. The telescopic cylinder 201 is selected from high-quality hydraulic or pneumatic cylinders to ensure stable output of the press-fitting force and smooth and reliable press-fitting process. The connecting piece 202 is made of high-strength aluminum alloy or steel, with a delicate and reasonable structure, which firmly connects the telescopic cylinder 201 and the press-fitting head 204 to ensure smooth power transmission, and provides accurate installation positions for the pressure sensor 2031 and the distance measuring sensor 2032, facilitating real-time and accurate monitoring of the press-fitting process. The pressure sensor 2031 and the distance measuring sensor 2032 of the detection unit 203 are selected from high-precision and high-reliability products, with accurate installation positions. The pressure sensor 2031 senses the press-fitting pressure in real time, and the distance measuring sensor 2032 accurately measures the displacement of the press-fitting head 204. The two work together, and once the pressure or displacement is abnormal, the control system (which can be built-in in the rack 1, not shown in detail) can adjust the action of the telescopic cylinder 201 in time, effectively avoiding the problem of insufficient press-fitting, and greatly improving the press-fitting precision. The threaded sleeve 2041 of the press-fitting head 204 is made of stainless steel or alloy steel, with very high thread accuracy, facilitating tight thread connection with the press head 2042, and being able to withstand the strong torque during press-fitting to ensure stable press-fitting process. The press head 2042 is made of quenched steel or hard alloy, with high hardness and strong wear resistance, and will not deform during frequent press-fitting operations, ensuring the press-fitting quality. The flexible sleeve 2043 is made of soft materials such as rubber or polyurethane, which can ensure the negative pressure adsorption effect by virtue of good flexibility, stably adsorb the bowl-shaped plug, and effectively protect the surface of the bowl-shaped plug from being scratched, ensuring the appearance quality of the product.

[0020] With reference to Fig. 2 , the workbench 3 is located on the lower side of the telescopic cylinder 201 of the rack 1, including a support table 301 and a buffer pad 302. The support table 301 is made of cast iron or steel to provide stable support for the buffer pad 302, ensuring that the buffer pad will not shift during the press-fitting process. The buffer pad 302 is made of elastic materials such as rubber or silicone, and is reliably pasted or fixed with the support table 301, which can effectively buffer the impact force during press-fitting, protect the cylinder barrel (a workpiece placed on the buffer pad 302 and matched with the bowl-shaped plug) from being damaged, and accurately position the cylinder barrel to ensure the accuracy of the press-fitting position of the bowl-shaped plug.

[0021] With reference to Fig. 2, the clamping assembly 4 is arranged between the buffer pad 302 and the press-fitting head 204 on the rack 1, and comprises a screw rod 401, a moving plate 402 and a pneumatic clamping jaw 403. The screw rod 401 is made of high-strength alloy steel, has high thread accuracy and excellent surface hardness, and can accurately drive the moving plate 402 to move when rotating. The moving plate 402 is made of aluminum alloy or steel material, has a structure convenient for installing the pneumatic clamping jaw 403, and moves smoothly on the guide rail without resistance, so that the pneumatic clamping jaw 403 can quickly and accurately approach or move away from the bowl-shaped plug. The pneumatic clamping jaw 403 is a mature product on the market, has a reliable air source interface connection, stable and accurate clamping action, can firmly clamp the bowl-shaped plug, and prevents the bowl-shaped plug from falling during the transfer process, thereby laying a foundation for the subsequent press-fitting process.

[0022] With reference to Fig. 3 The air nozzle 5 is made of copper alloy or stainless steel, has excellent sealing performance when connected with the negative pressure hole, effectively prevents air leakage, and ensures stable operation of the negative pressure suction system. When the air nozzle 5 is connected with a negative pressure source, air is smoothly sucked out through the negative pressure hole under the action of negative pressure, so that the flexible sleeve 2043 has a strong negative pressure suction force, further stably sucks the bowl-shaped plug, and cooperates with the clamping of the pneumatic clamping jaw 403, thereby greatly improving the stability and reliability of the bowl-shaped plug transfer process.

[0023] The implementation principle of the bowl-shaped plug press-fitting equipment according to the embodiment of the application is as follows:

[0024] In a mechanical product production workshop, the bowl-shaped plug press-fitting equipment is installed on a stable working platform, so that the rack 1 is fixed firmly and cooperates with surrounding auxiliary equipment such as material conveying and workpiece positioning, thereby ensuring the coherence and stability of the entire press-fitting process.

[0025] When the bowl-shaped plug press-fitting operation is needed, the operator first places the bowl-shaped plug to be press-fitted on the buffer pad 302 of the workbench 3. The buffer pad 302 is made of elastic materials such as rubber or silicone, can effectively buffer the impact force during press-fitting, protect the bowl-shaped plug and the workpiece below, and provide a certain positioning reference for the bowl-shaped plug, so that the initial position of the bowl-shaped plug is relatively stable.

[0026] Subsequently, the operator starts the screw rod 401 of the clamping assembly 4. The screw rod 401 is usually driven to rotate by a motor through belt or chain transmission, has high thread accuracy, and has a surface treated by quenching to improve wear resistance and transmission accuracy. The rotation of the screw rod 401 drives the moving plate 402 to move along the guide rail on the rack 1, so that the pneumatic clamping jaw 403 quickly and accurately approaches the bowl-shaped plug. The pneumatic clamping jaw 403 is selected to have a suitable clamping force, and the clamping jaw part is wrapped with soft materials such as polyurethane or rubber to prevent the bowl-shaped plug from being clamped, and accurately clamps the bowl-shaped plug.

[0027] Then, the air nozzle 5 is connected with a negative pressure source (such as a vacuum pump, the vacuum degree can be adjusted according to the bowl-shaped plug adsorption demand, under the action of negative pressure, air is extracted through the negative pressure hole in the threaded sleeve 2041, the pressure head 2042 and the flexible sleeve 2043, the aperture and distribution of the negative pressure hole are optimized and designed, so that the flexible sleeve 2043 surface generates sufficient negative pressure adsorption force, further firmly adsorbs the bowl-shaped plug, and even in the moving process, the bowl-shaped plug can be ensured to be closely attached to the press-fitting head 204.

[0028] After that, the control screw rod 401 is reversed, the moving plate 402 drives the pneumatic clamping jaw 403 to move, and the bowl-shaped plug is released to the lower side of the press-fitting head 204. At this time, the telescopic cylinder 201 of the press-fitting assembly 2 is started, the telescopic cylinder 201 is generally selected to be a hydraulic cylinder or an air cylinder, the extension speed of the piston rod of the telescopic cylinder 201 can be adjusted, the press-fitting head 204 is driven to move downward, and the bowl-shaped plug is press-fitted into the cylinder barrel placed on the buffer pad 302 and matched with the bowl-shaped plug.

[0029] During the press-fitting process, the pressure sensor 2031 of the detection unit 203 monitors the press-fitting pressure in real time, and the distance sensor 2032 monitors the displacement of the press-fitting head 204 in real time. The pressure sensor 2031 and the distance sensor 2032 transmit the monitoring data to the control system in real time, and the control system judges according to the preset press-fitting parameters (such as pressure threshold, displacement range, etc., which can be set in the control system in advance according to different product requirements). Once the pressure or displacement is abnormal, the control system immediately issues an instruction to adjust the action of the telescopic cylinder 201, such as slowing down the extension speed of the piston rod, pausing the press-fitting, or increasing the pressure, so as to avoid problems such as insufficient press-fitting and excessive press-fitting, and ensure the press-fitting quality of the bowl-shaped plug.
