Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a tooling for installing a core plate liner. Background Technology

[0002] In the maintenance of the fourth-level core plate of large track maintenance machinery, replacing the core plate liner is a critical task. Due to the interference fit between the core plate liner and the core plate, the current installation method is not only inefficient but also highly prone to component damage. Currently, the common installation method is hammering, which is not only labor-intensive and time-consuming but also has a 40% failure rate for the core plate liner. Given that each core plate liner costs between 700 and 3000 yuan, the high cost of wear and tear urgently needs to be addressed. To standardize and improve the efficiency of core plate liner installation and reduce the probability of damage, a specialized installation tool has been developed. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a core plate liner installation fixture, which enables efficient and high-quality installation of the core plate liner.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A mandrel liner installation fixture includes a guide post, on which a pressing module and a torque arm assembly are sleeved. The guide post includes a smooth lower section for fitting the mandrel and the mandrel liner, and a threaded upper section for connecting the torque arm assembly. The smooth lower section is provided with a lower limiting member for limiting the bottom of the mandrel. The pressing module is movably sleeved on the guide post between the mandrel liner and the torque arm assembly, so as to press the mandrel liner into the mandrel by adjusting with the torque arm assembly.

[0005] Preferably, the pressing module includes a hemispherical pressing block that matches the shape of the mandrel liner and a pressing plate disposed above the hemispherical pressing block. The hemispherical pressing block is made of nylon, and the pressing plate is made of steel plate.

[0006] Preferably, the lower limiting member is detachably connected to the smooth lower section of the guide post.

[0007] Preferably, the lower part of the smooth lower section is provided with a slot, and the lower limiting member is provided with a U-shaped locking part so that it can be locked into the slot.

[0008] Preferably, an upper limit stop is also connected above the torque arm assembly on the thread, and the upper limit stop is threadedly sleeved in the upper section of the thread.

[0009] Preferably, the torque arm assembly includes an adjusting sleeve threaded into the upper section of the thread, and a torque arm is connected to the side of the adjusting sleeve.

[0010] Preferably, the diameter of the upper threaded section is slightly smaller than the diameter of the smooth lower section.

[0011] The advantages of this utility model using the above technical solution are: 1. The tooling in this application replaces the traditional hammering installation method with press-fitting, which standardizes the installation process of the core plate liner. It not only speeds up the installation but also greatly reduces the impact of human factors (such as uneven hammering force in different places) on the installation quality.

[0012] 2. When using the tooling in this application, pressure can be applied evenly and stably, which helps to significantly reduce the probability of damage to the disc liner during installation, specifically within 5%, effectively saving costs.

[0013] 3. In the tooling of this application, the pressing module uses a combination of nylon pressing blocks and steel plates. The nylon pressing blocks can protect the chip pads made of nylon material from damage, while the steel plates can ensure the reliability of pressing. Attached Figure Description

[0016] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. In the description of this specification, the reference to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., means that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0017] like Figure 1-2As shown, in this embodiment, the mandrel liner mounting fixture includes a guide post 1, on which a press-fit module 2 and a torque arm assembly 3 are sleeved. The guide post 1 includes a mounting bracket for fitting the mandrel ( Figure 1 (Not shown in the diagram, but specifically located below the center plate liner during installation) and the smooth lower section 11 of the center plate liner 4 and the threaded upper section 12 for connecting the torque arm assembly 3. The smooth lower section 11 is provided with a lower limiting member 5 for limiting the bottom of the center plate. The pressing module 2 is movably sleeved on the guide post 1 between the center plate liner 4 and the torque arm assembly 6, so as to press the center plate liner 4 into the center plate according to the adjustment of the torque arm assembly 3. The above-mentioned installation fixture can apply pressure to the center plate liner evenly and stably, achieving high-quality installation.

[0018] Regarding the disassembly and assembly of the mandrel liner 4 and the mandrel with the tooling during installation, there are two methods. One is to first remove the torque arm assembly 3 and the press-fit module 2, and then insert it from the upper end of the guide post 1. The other is to make the lower limit piece 5 and the smooth lower section 11 detachable, and then insert them from the lower end of the guide post 1. The advantage of choosing the latter is that disassembly and assembly from the smooth surface of the smooth lower section 11 is not only quick, but also less likely to damage the mandrel liner 4 and the inner hole of the mandrel.

[0019] Furthermore, regarding the setting of the lower limit component 5, it can be, but is not limited to, the following structures: the first type, such as... Figure 1 As shown, a slot 111 is formed in the lower part of the smooth lower section 11, and a U-shaped locking part is provided on the lower limiting member 5 so that it can be locked into the slot. The second method is to form a radial through hole in the smooth lower section and achieve this by inserting a limiting rod.

[0020] In one specific embodiment, in order to further reduce the probability of damage to the disc liner 4 during installation, the following structural settings are made: the pressing module 2 includes a hemispherical pressing block 21 that matches the disc liner 4 and a pressing plate 22 disposed above the hemispherical pressing block 21. The hemispherical pressing block 21 is made of nylon to protect the disc liner to a certain extent; the pressing plate 22 is made of steel plate to ensure pressing reliability.

[0021] In one specific embodiment, to prevent the torque arm assembly 3 and other structures from accidentally coming off the upper end of the guide post 1 during operation, an upper limit member 6, such as a common nut, can be connected to the upper part of the threaded upper section 12.

[0022] In one specific embodiment, the torque arm assembly 3 can be structured as follows: the torque arm assembly 3 includes an adjusting sleeve 31 threadedly connected to the upper thread section 12, and a torque arm 32 is connected to the side of the adjusting sleeve 31. Specifically, two arms can be symmetrically connected, making the operation smoother and more convenient.

[0023] In one specific embodiment, the diameter of the upper threaded section 12 is slightly smaller than the diameter of the smooth lower section 11, so that the torque arm assembly 3 can be constrained on the upper threaded section 12.

[0024] Operating principle: Step 1: First, remove the lower limit piece 5 from the guide post 1. Then, insert the mandrel liner 4 and the mandrel from the lower end of the guide post 1 onto its smooth lower section 11. Then, snap the lower limit piece 5 onto the guide post 1 to limit the bottom of the mandrel during press-fitting.

[0025] Step 2: Align and attach the pressing module (hemispherical pressing block 21 and pressing plate 22) to the core plate liner 4, then rotate the torque arm assembly and slowly press down the pressing module 2 so that the core plate liner 4 can be high-quality interference-fitted into the core plate.

[0026] Step 3: Rotate the torque arm assembly 3 in the opposite direction to release the restriction on the press-fit module and the core plate liner. Then remove the lower limit piece 5 and drag the tooling so that its lower section can be smoothly removed from the top of the assembled core plate and core plate liner. The tooling can then be removed to complete the assembly work.

[0027] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0028] Any aspects of this utility model not described in detail are common knowledge to those skilled in the art.
