[0033] In order to solve the problem of low universality of the fixture for installing oil seals in the prior art, the present application provides an auxiliary installation tooling and an installation tool having the same.

[0034] As Figure 1 and Figure 2 shown, the auxiliary installation tooling is used to assist the knocking piece to install the piece to be installed on the mechanical equipment. The auxiliary installation tooling includes a support and a matching structure 20. The support structure 10 is arranged on the mechanical equipment. The matching structure 20 has a matching convex part for extending into the concave part of the piece to be installed, and at least part of the outer surface of the matching structure 20 is used for the knocking piece to knock. Among them, there are multiple matching structures 20, and the multiple matching structures 20 are arranged at intervals around the support structure 10, and each matching structure 20 is movably arranged on the support structure 10, so as to adjust the position of the matching convex part of each matching structure 20 when each matching structure 20 moves towards or away from the support structure 10.

[0035] Applying the technical solution of this embodiment, the auxiliary installation tooling is used to assist the knocking member to install the to-be-installed part on the mechanical equipment. The auxiliary installation tooling includes a support structure 10 and a matching structure 20. The support structure 10 is arranged on the mechanical equipment. The matching structure 20 has a matching convex part for extending into the concave part of the to-be-installed part, and at least part of the outer surface of the matching structure 20 is used for the knocking member to strike. Wherein, there are multiple matching structures 20, and the multiple matching structures 20 are arranged at intervals around the support structure 10, and each matching structure 20 is movably arranged on the support structure 10, so as to adjust the position of the matching convex part of each matching structure 20 when each matching structure 20 moves towards or away from the support structure 10. In this way, when the staff installs the to-be-installed part on the mechanical equipment, first place the support structure 10 on the mechanical equipment, then operate the multiple matching structures 20 to move, so that the matching convex parts of the respective matching structures 20 match the concave parts of the to-be-installed part, and extend the matching convex parts into the concave parts of the to-be-installed part. Finally, strike the matching structure 20 with the knocking member to install the to-be-installed part on the mechanical equipment, so that the auxiliary installation tooling can match to-be-installed parts of different specifications and sizes, improving the versatility of the auxiliary installation tooling, thereby solving the problem of low versatility of the fixtures for installing oil seals in the prior art, reducing the work difficulty of the staff, and improving the work efficiency of the staff. At the same time, the arrangement mode of the multiple matching structures 20 improves the force uniformity of the to-be-installed part and prolongs the service life of the to-be-installed part.

[0036] In this embodiment, the mechanical equipment is one of equipment such as a reducer and a drum on which an oil seal is installed.

[0037] In this embodiment, the to-be-installed part is an oil seal and is arranged in a ring shape.

[0038] Specifically, a concave part is arranged on the lip side of the oil seal.

[0039] In this embodiment, the knocking member is a rubber hammer.

[0040] In this embodiment, the support structure 10 is arranged in a cylindrical shape.

[0041] In this embodiment, the number of the arranged matching structures 20 is six.

[0042] It should be noted that the number of the arranged matching structures 20 is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the matching structure 20 is three, or four, or five, or seven, or more.

[0043] Such as Figure 1 and Figure 2As shown, the fitting structure 20 includes a mounting member 21 and a fitting member 22. At least part of the outer surface of the mounting member 21 is for being struck by a striking member. The fitting member 22 is arranged on the mounting member 21, and one end of the fitting member 22 away from the mounting member 21 is a fitting convex portion. Among them, the mounting member 21 is a metal member, and the fitting member 22 is a polyurethane member. In this way, the setting mode of the mounting member 21 improves the structural strength of the mounting member 21, avoids damage to the mounting member 21 when the staff strikes the mounting member 21, thereby prolonging the service life of the mounting member 21, and further prolonging the service life of the fitting structure 20. At the same time, the setting mode of the fitting member 22 improves the structural strength of the fitting member 22, also improves the oil resistance and wear resistance of the fitting member 22, enables the fitting member 22 to match the member to be installed, avoids damage to the member to be installed, and thereby prolongs the service life of the member to be installed.

[0044] As Figure 1 shown, the mounting member 21 has a mounting recess 211. The fitting member 22 includes a first plate-like structure 221 and a second plate-like structure 222 connected to each other. The first plate-like structure 221 is arranged in the mounting recess 211, and the second plate-like structure 222 is arranged on the plate surface of the first plate-like structure 221 and is arranged at an angle with the first plate-like structure 221. One end of the second plate-like structure 222 away from the first plate-like structure 221 is a fitting convex portion. Among them, a step surface 212 for limiting and stopping the first plate-like structure 221 is arranged in the mounting recess 211. In this way, on the one hand, the above setting realizes the installation between the mounting member 21 and the fitting member 22 through the mounting recess 211, the first plate-like structure 221 and the second plate-like structure 222; on the other hand, the mounting recess 211 limits and stops the first plate-like structure 221 through the step surface 212, avoiding the first plate-like structure 221 from coming out of the mounting recess 211, thereby improving the fitting stability of the fitting member 22.

[0045] In this embodiment, the mounting member 21 is arranged in a rectangular sleeve shape, and an opening is arranged on one side of the mounting member 21 close to the fitting member 22 to form a "convex"-shaped mounting cavity with the cavity of the mounting member 21. At least part of the second plate-like structure 222 extends out of the opening to form a fitting convex portion.

[0046] As Figure 1 and Figure 2 shown, an interference fit is provided between at least part of the inner wall of the mounting recess 211 and the outer surface of the first plate-like structure 221; and / or, an interference fit is provided between at least part of the inner wall of the mounting recess 211 and the outer surface of the second plate-like structure 222. In this way, the above setting realizes the connection between the mounting member 21 and the fitting member 22, reduces the installation difficulty of the staff, and improves the convenience of the staff's installation.

[0047] Specifically, the second plate-like structure 222 is an arc-shaped plate. In this way, the above setting makes the arc-shaped plate match the installation recess 211 of the component to be installed, increasing the contact area between the arc-shaped plate and the component to be installed, and improving the fitting stability and smoothness of the fitting 22.

[0048] As Figure 1 and Figure 2 shown, the support structure 10 has a threaded section, and the auxiliary installation tooling further includes a driving structure 30. The driving structure 30 is sleeved on the support structure 10 and is in threaded cooperation with the support structure 10, and the driving structure 30 is drivingly connected to the fitting structure 20. Among them, during the process of screwing the driving structure 30, the driving structure 30 moves along the extension direction of the support structure 10 to drive the fitting structure 20 to move towards or away from the support structure 10. In this way, the above setting enables the staff to drive the fitting structure 20 only by screwing the driving structure 30, so that the driving structure 30 does not need to be provided with a supporting air supply device or oil supply device, thereby reducing the operation cost of the auxiliary installation tooling, reducing the operation difficulty of the staff, and improving the work efficiency of the staff.

[0049] In this embodiment, the driving structure 30 is arranged in a cylindrical shape.

[0050] In an embodiment not shown in the drawings, a linear module can also be provided on the support structure.

[0051] As Figure 1 and Figure 2 shown, the auxiliary installation tooling further includes a transmission rod 40. The driving structure 30 is drivingly connected to the fitting structure 20 through the transmission rod 40, and both ends of the transmission rod 40 are rotatably connected to the driving structure 30 and the fitting structure 20 respectively. In this way, the above setting realizes the connection between the driving structure 30 and the fitting structure 20 through the transmission rod 40, so as to realize the movement of the driving structure 30 driving the transmission rod 40 to drive the fitting structure 20 towards or away from the support structure 10.

[0052] In this embodiment, the transmission rod 40 is a connecting rod.

[0053] Specifically, a plurality of first connection structures 31 are arranged at intervals around the support structure 10 on the outer peripheral surface of the driving structure 30, and the rotating member is inserted through the first connection structures 31 and the transmission rod 40 to rotatably connect the transmission rod 40 to the driving structure 30.

[0054] Specifically, a second connection structure 23 is arranged on the side of the fitting structure 20 close to the transmission rod 40, and the rotating member is inserted through the second connection structures 23 and the transmission rod 40 to rotatably connect the transmission rod 40 to the fitting structure 20.

[0055] Optionally, the rotating member is one of a pin shaft or a pin.

[0056] As Figure 2 shown, the auxiliary installation tooling further includes an operating structure 50. The operating structure 50 is arranged on the driving structure 30, and the operating structure 50 is used to drive the driving structure 30 to rotate. In this way, the above arrangement enables the staff to operate the driving structure 30 through the operating structure 50, thereby realizing the rotation of the driving structure 30 and improving the work efficiency of the staff.

[0057] In this embodiment, the operating structure 50 is rod-shaped, and a sphere is arranged at one end of the operating structure 50 away from the driving structure 30, which is beneficial to the operation of the staff, avoids scratching the staff, and improves the operation safety of the staff.

[0058] As Figure 1 and Figure 2 shown, the auxiliary installation tooling further includes an abutting plate 60. The abutting plate 60 is arranged at the bottom of the supporting structure 10, and the abutting plate 60 is used for abutting against the mechanical equipment. In this way, on the one hand, the above arrangement increases the contact area between the auxiliary installation tooling and the mechanical equipment and improves the stability of the auxiliary installation tooling; on the other hand, it increases the weight of the supporting structure 10 and the friction between the auxiliary installation tooling and the mechanical equipment, so that when the driving structure 30 rotates, the supporting structure 10 will not rotate along with the driving structure 30, ensuring that the driving structure 30 can move along the extension direction of the supporting structure 10, thereby improving the movement stability of the driving structure 30 and also improving the reliability of the auxiliary installation tooling.

[0059] In this embodiment, the abutting plate 60 is arranged in a circular plate shape.

[0060] The present application also provides an installation tool, which includes the auxiliary installation tooling and a knocking member. The knocking member knocks the abutting structure of the auxiliary installation tooling to install the to-be-installed part on the mechanical equipment. Among them, the auxiliary installation tooling is the above-mentioned auxiliary installation tooling.

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

[0062] The auxiliary installation tooling is used to assist the knocking piece in installing the piece to be installed onto the mechanical equipment. The auxiliary installation tooling includes a support structure and a mating structure. The support structure is arranged on the mechanical equipment.

Wherein, there are multiple mating structures, and the multiple mating structures are arranged at intervals around the support structure. Each mating structure is movably arranged on the support structure so as to adjust the position of the mating convex portion of each mating structure when each mating structure moves towards or away from the support structure. In this way, when the staff installs the piece to be installed onto the mechanical equipment, first place the support structure on the mechanical equipment, then operate the multiple mating structures to move so that the mating convex portions of the respective mating structures match the recesses of the piece to be installed, and extend the mating convex portions into the recesses of the piece to be installed. Finally, strike the mating structure with the knocking piece to install the piece to be installed onto the mechanical equipment, thereby enabling the auxiliary installation tooling to match pieces to be installed with different specifications and sizes, improving the versatility of the auxiliary installation tooling, and further solving the problem of low versatility of the fixtures for installing oil seals in the prior art, reducing the working difficulty of the staff and improving the working efficiency of the staff.
