Description

Technical Field

[0001] This utility model relates to the field of engine manufacturing equipment technology, specifically to an automatic adsorption-type pressing tool. Background Technology

[0002] Due to advancements in engine technology, aluminum alloys are now widely used for weight reduction and better heat dissipation. However, the combustion chamber operates at high temperatures, so ferrous components are typically pressed into the aluminum alloy parts to contact the combustion chamber and extend engine life.

[0003] Traditional press-fitting methods require first placing the iron-containing accessory on the engine, then manually pressing and aligning it, and finally using a press-fitting tool for final pressing. The entire assembly of the iron-containing accessory requires these two steps in sequence. Furthermore, the manual initial pressing and alignment is labor-intensive and inefficient. To address these issues, we have proposed an automatic adsorption press-fitting tool. Utility Model Content

[0005] This utility model provides the following technical solution: an automatic adsorption-type pressing tool for installing iron-containing accessories on an engine, comprising: a pressing rod, a connecting end fixedly installed at the end of the pressing rod, and the end of the pressing rod away from the connecting end can be connected to a hydraulic press; the connecting end has an assembly hole inside, and a strong magnet is installed inside the assembly hole, with an interference fit between the strong magnet and the assembly hole; a threaded sleeve is fixedly embedded inside the connecting end, and a threaded rod is threadedly connected to the connecting end through the threaded sleeve; a pressure plate is fixedly connected to the end of the threaded rod passing through the threaded sleeve; an adsorption head is fixedly installed on the side of the pressure plate; the adsorption head can be inserted into the iron-containing accessory, and the adsorption head can also be magnetically connected to the iron-containing accessory through the strong magnet.

[0006] Preferably, the outer surface of the press rod is formed with a knurled surface by a knurling process.

[0007] Preferably, the outer surface of the pressure plate is composed of a flat surface and an arc-shaped surface, and the flat surface and the arc-shaped surface are connected end to end.

[0008] Preferably, a rounded corner layer is provided at the connection between the adsorption head and the pressure plate, and a hemispherical head is fixedly installed at the end of the adsorption head.

[0009] Preferably, the opening connecting the threaded sleeve and the threaded rod is a chamfered opening, and the size of the chamfered opening is larger than the size of the end face of the threaded rod.

[0010] Preferably, the outer surface of the threaded sleeve is further provided with a raised ring for increasing the contact area with the connecting end.

[0011] Preferably, the axis of the threaded rod coincides with the axis of the adsorption head.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This automatic adsorption-type pressing tool uses the threaded engagement between the threaded rod and the threaded sleeve to fix the adsorption head to the connecting end of the pressing rod. The connecting end is interference-fitted with a strong magnet through the assembly hole. Therefore, after the adsorption head is inserted into the iron-containing accessory, it can automatically be attracted to the adsorption head by the magnet. The pressing rod can also be mounted on a hydraulic press. Therefore, after aligning the iron-containing accessory with the predetermined installation position, the hydraulic press can be directly started to output pressure for pressing, reducing the installation steps of the iron-containing accessory and improving the production efficiency of pressing.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4An automatic adsorption-type press-fitting tool is used to install iron-containing accessories on an engine. It includes: a press-fitting rod 1, with a connecting end 2 fixedly mounted at one end. The end of the press-fitting rod 1 away from the connecting end 2 can be connected to a hydraulic press. The connecting end 2 has an assembly hole 6 inside, and a strong magnet 5 is installed inside the assembly hole 6, with an interference fit between the strong magnet 5 and the assembly hole 6. The outer surface of the press-fitting rod 1 is knurled to form a knurled surface 12, increasing the friction of the outer surface of the press-fitting rod 1, thus strengthening the connection between the press-fitting rod 1 and the hydraulic press, reducing operational errors caused by slippage, and improving the safety and accuracy of operation.

[0021] A threaded sleeve 8 is fixedly embedded inside the connecting end 2, and a threaded rod 7 is threadedly connected to the connecting end 2 through the threaded sleeve 8. The opening where the threaded sleeve 8 connects to the threaded rod 7 is a chamfered opening 9, and the size of the chamfered opening 9 is larger than the size of the end face of the threaded rod 7. The design of the chamfered opening 9 serves a guiding function, allowing the threaded rod 7 to enter the threaded sleeve 8 more smoothly during installation, reducing jamming and wear during the installation process, improving installation efficiency and the service life of the component. A pressure dividing plate 3 is fixedly connected to the end of the threaded rod 7 that passes through the threaded sleeve 8, and the threaded rod 7 serves to transmit pressure. The pressure transmitted from the hydraulic press through the pressing rod is accurately transferred to the pressure plate 3, which then evenly applies the pressure to the iron-containing accessories, achieving stable pressing operation. Simultaneously, the threaded connection allows for easy adjustment of the position of the pressure plate 3 to accommodate the pressing needs of iron-containing accessories of different sizes and shapes. The outer surface of the threaded sleeve 8 is also fixedly provided with a raised ring to increase the contact area with the connecting end 2, making the threaded sleeve 8 more securely installed within the connecting end 2 and better able to withstand various forces generated during the pressing process, reducing the friction between the threaded sleeve 8 and the connecting end. The loosening and relative displacement between the heads 2 improve the stability and reliability of the entire connection structure. An adsorption head 4 is fixedly installed on the side of the pressure plate 3. The axis of the threaded rod 7 coincides with the axis of the adsorption head 4. The adsorption head 4 can be inserted into iron-containing accessories, and it can also be magnetically connected to the iron-containing accessories via a strong magnet 5. The outer surface of the pressure plate 3 is composed of a flat surface 10 and an arc-shaped surface, with the flat surface 10 and the arc-shaped surface connected end-to-end. The flat surface 10 can be used to engage tools such as wrenches, allowing the user to rotate the pressure plate 3 to tighten the threaded rod 7. The connection between the adsorption head 4 and the pressure plate 3... A rounded corner layer 11 is provided at the joint. The rounded corner layer 11 can reduce stress concentration. During the press-fitting process, when subjected to greater pressure, it can prevent cracks or damage at the joint, improve the strength and durability of the component, and extend the service life of the tool. In addition, a hemispherical head 13 is fixedly installed at the end of the adsorption head 4. The design of the hemispherical head 13 makes the adsorption head more smooth when in contact with iron-containing accessories, reducing damage to the surface of iron-containing accessories. Especially when inserting into the iron-containing accessories, it can enter more easily, avoiding scratches or jamming, improving the smoothness of operation and the integrity of iron-containing accessories.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
