[0032] In order to solve the problem of low installation efficiency when workers install airtight springs in the prior art, the present application provides a compression tool.

[0033] like Figures 1 to 3As shown, the compression tooling is used to compress the part to be compressed 2 on the mechanical device 1, and the compression tooling includes a support structure 10, a drive assembly 20 and an abutment structure 30. The support structure 10 is detachably arranged on the mechanical device 1. The drive assembly 20 is arranged on the support structure 10. The abutment structure 30 is arranged on the drive assembly 20, and the drive assembly 20 is driven and connected to the abutment structure 30 to drive the abutment structure 30 to move in a direction toward or away from the support structure 10. The abutment structure 30 has a plurality of abutment recesses 31, and each abutment recess 31 is arranged in a one-to-one correspondence with each mounting recess 101 in the mechanical device 1. Among them, one end of the part to be compressed 2 is located in the mounting recess 101, and the other end of the part to be compressed 2 is located in the abutment recess 31, so that when the abutment structure 30 moves in the direction toward the support structure 10, the part to be compressed 2 is compressed to a preset position.

[0034] Applying the technical solution of this embodiment, the compression tooling is used to compress the part to be compressed 2 on the mechanical equipment 1, and the compression tooling includes a support structure 10, a drive assembly 20 and an abutment structure 30. The support structure 10 is detachably arranged on the mechanical equipment 1. The drive assembly 20 is arranged on the support structure 10. The abutment structure 30 is arranged on the drive assembly 20, and the drive assembly 20 is driven and connected to the abutment structure 30 to drive the abutment structure 30 to move in a direction toward or away from the support structure 10. The abutment structure 30 has a plurality of abutment recesses 31, and each abutment recess 31 is arranged in a one-to-one correspondence with each mounting recess 101 in the mechanical equipment 1. Among them, one end of the part to be compressed 2 is located in the mounting recess 101, and the other end of the part to be compressed 2 is located in the abutment recess 31, so that when the abutment structure 30 moves in the direction toward the support structure 10, the part to be compressed 2 is compressed to a preset position. In this way, when the staff needs to compress the airtight spring and install the valve lock block, the staff first installs the support structure 10 of the compression tool on the diesel engine, then places the airtight spring to be compressed in the installation recess 101 of the diesel engine, and places the end of the airtight spring away from the installation recess 101 in the abutment recess 31. Finally, the staff starts the drive assembly 20 to drive the abutment structure 30 to move toward the support structure 10. During the movement of the abutment structure 30, the airtight spring is compressed. After the airtight spring is compressed to the preset position, the staff can perform subsequent installation operations. The above arrangement not only reduces the labor intensity of the staff, but also enables the staff to compress multiple airtight springs at the same time, thereby improving the installation efficiency of the staff, thereby solving the problem of low installation efficiency of the staff when installing the airtight spring in the prior art.

[0035] In this embodiment, the mechanical equipment 1 is a diesel engine.

[0036] In this embodiment, the component to be compressed 2 is a gas-tight spring or a valve spring.

[0037] In this embodiment, the support structure 10 is a double-headed screw. In this way, the above arrangement can disperse and absorb the vibration and impact generated during the compression process, protect the mechanical device 1 from damage, and extend the service life of the mechanical device 1.

[0038] In this embodiment, the number of the abutting recesses 31 is four.

[0039] It should be noted that the number of abutment recesses 31 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the number of abutment recesses 31 is three, five, six, seven, eight, or more.

[0040] In this embodiment, the surface of the abutting structure 30 is processed to make it flat and smooth to avoid damage to the component to be compressed.

[0041] like Figures 1 to 3 As shown, the drive assembly 20 includes a drive structure 21 and at least two relatively arranged transmission structures 22. A transmission space 23 is formed between the at least two transmission structures 22, and at least part of the drive structure 21 is located in the transmission space 23. One end of the transmission structure 22 is connected to the support structure 10, and the other end of the transmission structure 22 is connected to the abutment structure 30. The drive structure 21 is driven and connected to the transmission structure 22 to drive the transmission structure 22 to drive the abutment structure 30 to move. In this way, the above arrangement, on the one hand, realizes the drive connection of the drive structure 21 to the abutment structure 30 through the transmission structure 22; on the other hand, compared with the transmission mode of a single transmission structure 22, the at least two relatively arranged transmission structures 22 ensure the stability of the movement of the abutment structure 30, thereby ensuring the compression stability of the compression tooling on the compression member 2.

[0042] In this embodiment, there are two transmission structures 22 .

[0043] It should be noted that the number of transmission structures 22 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of transmission structures 22 is three, four, six, seven, or more.

[0044] like Figure 1 and Figure 2As shown, the transmission structure 22 includes a first transmission part 221 and a second transmission part 222 that are hinged to each other. The end of the first transmission part 221 away from the second transmission part 222 is rotatably connected to the abutment structure 30, and the end of the second transmission part 222 away from the first transmission part 221 is rotatably connected to the support structure 10. In this way, the above arrangement, through the hinge connection between the first transmission part 221 and the second transmission part 222, on the one hand, expands the adjustment range of the transmission structure 22, so that the transmission structure 22 can adjust the position of the abutment structure 30 by adjusting the angle between the first transmission part 221 and the second transmission part 222 to adapt to different specifications and sizes of the compression parts 2, thereby improving the versatility of the compression tool. On the other hand, the hinge connection reduces the shaking and instability of the abutment structure 30 during movement, improves the compression controllability of the compression tool, and reduces the degree of damage to the compression parts 2. At the same time, the above arrangement also makes the transmission structure 22 simpler, reduces production costs, and reduces the difficulty of installation and disassembly for workers, thereby improving work efficiency.

[0045] Specifically, when installing the support structure 10 on the mechanical equipment 1, the staff can first adjust the angle between the first transmission part 221 and the second transmission part 222 to drive the abutment structure 30 to move, thereby adapting to the parts 2 to be compressed of different specifications and sizes.

[0046] like Figure 1 and Figure 2As shown, the compression tooling also includes a connecting structure 40, which includes a first connecting structure 41, a second connecting structure, and a third connecting structure 42. The first connecting structure 41 is arranged between the first transmission part 221 and the second transmission part 222. The first transmission part 221 and the second transmission part 222 are both rotatably connected to the first connecting structure 41 to achieve a hinged connection between the first transmission part 221 and the second transmission part 222. The second connecting structure is arranged on the abutment structure 30, and the end of the first transmission part 221 away from the second transmission part 222 is rotatably arranged on the second connecting structure. The third connecting structure 42 is arranged on the support structure 10, and the end of the second transmission part 222 away from the first transmission part 221 is rotatably arranged on the third connecting structure 42. In this way, the above-mentioned arrangement, on the one hand, realizes the hinge between the first transmission part 221 and the second transmission part 222 through the first connecting structure 41, realizes the connection between the transmission structure 22 and the abutment structure 30 through the second connecting structure, and realizes the connection between the transmission structure 22 and the support structure 10 through the third connecting structure 42; on the other hand, it makes it possible for the first transmission part 221 and the second transmission part 222 to not directly contact each other, so that the transmission structure 22 does not need to directly contact the abutment structure 30 and the support structure 10, thereby reducing the damage caused by direct contact between the transmission structure 22, the abutment structure 30 and the support structure 10, extending the service life of each structure, and thereby improving the service life of the compression tooling.

[0047] like Figure 2 As shown, the first connecting structure 41 has a threaded hole 411, and the driving structure 21 is rod-shaped. The driving structure 21 has a threaded section 211, and at least a portion of the threaded section 211 is located in the threaded hole 411 and threadedly engaged with the threaded hole 411. During the screwing process of the driving structure 21, at least one first connecting structure 41 moves toward or away from another first connecting structure 41. Thus, the above arrangement enables the driving structure 21 to drive the transmission structure 22 through the threaded engagement between the driving structure 21 and the first connecting structure 41, and also enables the first connecting structure 41 to guide and position the first transmission portion 221 and the second transmission portion 222. This allows a worker to compress the compression member 2 by simply screwing the driving structure 21, thereby simplifying the operation process, reducing the operator's difficulty and labor intensity, and improving the operator's work efficiency. Furthermore, the compression tooling does not require a matching air supply device or oil supply device, thereby reducing the production cost of the compression tooling. At the same time, the above-mentioned setting realizes the compression of the compression part 2 by screwing the drive structure 21. Compared with cylinders, levers and other equipment, it ensures that the power output during the compression process is smooth and reliable, and can accurately control the displacement of the first connecting structure 41, thereby realizing precise compression of the compression part 2, improving the compression accuracy of the compression part 2, and ensuring the compression accuracy of the compression tooling.

[0048] In this embodiment, the driving structure 21 is a lead screw.

[0049] In this embodiment, the two oppositely disposed first connection structures 41 move in directions toward or away from each other.

[0050] In this embodiment, one end of the driving structure 21 is fixedly connected to one of the first connection structures 41 , and at least a portion of the threaded segment 211 is threadedly engaged with the other one of the first connection structures 41 .

[0051] In an embodiment not shown in the drawings, the threaded segment on the driving structure is a bidirectional threaded segment, and the two first connecting structures are respectively threadedly engaged with opposite threaded segments.

[0052] like Figure 1 and Figure 2 As shown, the abutment structure 30 has a mounting hole 32, and the compression tooling further includes a fastening structure 50, which passes through the mounting hole 32 and is connected to the second connecting structure. Thus, the above arrangement achieves a connection between the abutment structure 30 and the second connecting structure via the fastening structure 50, thereby enhancing the connection stability between the abutment structure 30 and the second connecting structure, preventing the abutment structure 30 from loosening or moving during movement, improving the operational reliability and stability of the abutment structure 30, and further ensuring the compression reliability and safety of the compression tooling. Furthermore, the above arrangement also facilitates the installation and removal of the abutment structure 30 by staff, improving the efficiency of installation and maintenance by staff.

[0053] In this embodiment, the fastening structure 50 is a bolt.

[0054] like Figure 1 and Figure 2 As shown, the abutment structure 30 has an abutment surface 33, and the abutment recess 31 has an abutment hole 311. Thus, the above arrangement allows the operator to ensure the connection accuracy between the abutment recess 31 and the compressed component 2 through the abutment hole 311, further improving the compression accuracy; and also allows the operator to install other tooling through the abutment hole 311, improving the operator's installation efficiency.

[0055] like Figures 1 to 3As shown, the abutment structure 30 is plate-shaped, and a plurality of abutment recesses 31 are spaced apart along the length or width direction of the abutment structure 30. In this way, the above arrangement makes the abutment structure 30 more uniform and stable in compressing the parts to be compressed 2, ensuring that the compression forces on each part to be compressed 2 are similar, thereby improving the uniformity of compression of the compression tool. At the same time, the above arrangement also avoids uneven force on the parts to be compressed 2, which may cause damage to the parts to be compressed 2, ensuring that the service life of each part to be compressed 2 can be guaranteed while compressing multiple parts to be compressed 2, thereby improving the versatility of the compression tool. At the same time, the above arrangement makes the formation of the abutment structure 30 simpler, easier to process and realize, and reduces the processing flexibility of the staff.

[0056] In this embodiment, the abutting structure 30 is in the shape of a rectangular plate.

[0057] In this embodiment, the four abutting recesses 31 are symmetrically distributed, with two provided along the length direction of the abutting structure 30 and two provided along the width direction of the abutting structure 30 , so as to further improve the compression uniformity of the abutting structure 30 when compressing the workpiece 2 to be compressed.

[0058] like Figure 2 As shown, the connecting structure 40 is block-shaped, and at least a portion of the connecting structure 40 is made of a hard material. This configuration provides the connecting structure 40 with sufficient strength and rigidity to withstand the compressive force generated by the compression tooling when compressing the workpiece 2. This prevents deformation of the components during the compression process that could damage the compression tooling, thereby improving the compression reliability and stability of the compression tooling.

[0059] like Figure 1 and Figure 2As shown, the compression tool further comprises a rotating structure 60, which comprises: a first rotating part 61 connected with the first connecting structure 41 through the first transmission part 221 and the second transmission part 222; a second rotating part 62 connected with the second connecting structure through the first transmission part 221; and a third rotating part 63 connected with the third connecting structure 42 through the second transmission part 222. In this way, the above arrangement realizes the connection between the first transmission part 221, the second transmission part 222 and the first connecting structure 41 through the first rotating part 61, realizes the hinging of the first transmission part 221 and the second transmission part 222, and avoids the phenomenon of offset loosening between the first transmission part 221, the second transmission part 222 and the first connecting structure 41, thereby ensuring the transmission stability and reliability of the transmission structure 22. Meanwhile, the above arrangement realizes the connection between the first transmission part 221 and the second connecting structure through the second rotating part 62, realizes the rotating of the first transmission part 221 and the second connecting structure, and avoids the phenomenon of offset loosening between the first transmission part 221 and the second connecting structure, thereby ensuring the operation stability and reliability of the transmission structure 22 and the abutting structure 30. The above arrangement realizes the connection between the second transmission part 222 and the third connecting structure 42 through the third rotating part 63, avoids the phenomenon of offset loosening between the second transmission part 222 and the third connecting structure 42, and ensures the operation stability and reliability of the transmission structure 22.

[0060] In the embodiment, the rotating structure 60 is a pin.

[0061] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

[0062] The compression tooling is used to compress the parts to be compressed on the mechanical equipment, and the compression tooling includes a support structure, a drive assembly and an abutment structure. The support structure is detachably arranged on the mechanical equipment. The drive assembly is arranged on the support structure. The abutment structure is arranged on the drive assembly, and the drive assembly is driven and connected to the abutment structure to drive the abutment structure to move in a direction toward or away from the support structure. The abutment structure has a plurality of abutment recesses, and each abutment recess is arranged in a one-to-one correspondence with each mounting recess in the mechanical equipment. Among them, one end of the part to be compressed is located in the mounting recess, and the other end of the part to be compressed is located in the abutment recess, so that when the abutment structure moves in the direction toward the support structure, the part to be compressed is compressed to a preset position. In this way, when the staff needs to compress the airtight spring and install the valve lock block, the staff first installs the support structure of the compression tooling on the diesel engine, then places the airtight spring to be compressed in the installation recess of the diesel engine, and places the end of the airtight spring away from the installation recess in the abutment recess. Finally, the staff starts the drive assembly to drive the abutment structure to move toward the support structure. During the movement of the abutment structure, the airtight spring is compressed. After the airtight spring is compressed to a preset position, the staff can perform subsequent installation operations. The above arrangement not only reduces the labor intensity of the staff, but also enables the staff to compress multiple airtight springs at the same time, thereby improving the installation efficiency of the staff, thereby solving the problem of low installation efficiency of the staff when installing the airtight spring in the prior art.
