Description

Technical Field

[0001] This application relates to the technical field of distribution protection, and particularly to a distribution protection tooling. Background Art

[0002] Distribution operation is to configure fixed pins for mechanical equipment to limit the freedom of movement between components of the mechanical equipment and ensure the reliability of the fastening of each fastener. During distribution operation, a large amount of iron filings are generated during drilling and reaming. If no protection is provided, the iron filings entering the mechanical equipment will damage the equipment.

[0003] A speed reducer is used to reduce the high-speed rotation of the prime mover to the low-speed rotation required by the working machine, and at the same time increase the torque. The speed reducer can provide a large output torque, adjust the output speed, protect the motor, and adapt to different working requirements. The speed reducer should be firmly installed on a stable and level foundation or base, the oil in the oil drain groove should be able to drain, and the cooling air circulation should be smooth. If the foundation of the speed reducer is unreliable, vibration and noise will be caused during operation, and the bearings and gears will be damaged. According to regulations, the installation of the speed reducer requires positioning pins to limit the freedom of movement between the speed reducer and the base and the reliability of the fastening of each fastener. Moreover, due to the high-speed operation of the speed reducer and the gears being high-precision parts, no foreign objects can enter the interior of the speed reducer. During distribution operation, a large amount of iron filings are generated during drilling and reaming. If no protection is provided, the iron filings entering the speed reducer will damage the speed reducer. Summary of the Invention

[0029] The following will be combined with the attached Figures 1 to 7 The embodiments of the technical solution of the present application are described in detail. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0030] Embodiment 1: Distribution protection tooling

[0031] In order to elaborate on the specific implementation of the distribution protection tooling of the present application, a single-piece distribution operation is taken as an example for explanation below.

[0032] like Figures 1 to 5, the distribution protection tooling in this embodiment is applicable to the distribution operation of mechanical equipment. The workpiece to be distributed has multiple holes penetrating the inside of the mechanical device, and other holes except the distribution operation hole 101 during the distribution operation are covered. The distribution protection tooling in this embodiment mainly consists of a second cover plate 21 and a second cover accessory 22. The second cover plate 21 is a flat plate structure, and its size is designed according to the distribution and size of the non-operation holes on the workpiece to be distributed, so as to ensure that these holes can be completely covered. For example, if the shape of the non-operation hole on the workpiece to be distributed is a cylindrical cavity, the second cover plate 21 can be set as a circular plate or a square plate covering the cylindrical cavity. The second cover accessory 22 is used to cooperate with the non-operation holes on the workpiece to be distributed to protect the non-operation holes on the workpiece to be distributed. The second cover accessory 22 is connected to the second cover plate and can be closely attached to the inner hole of the workpiece to form an effective protection. The shape of the second cover accessory 22 generally depends on the shape of the non-operation holes on the workpiece to be distributed, so as to realize the cooperation between the second cover accessory 22 and the non-operation holes, protect the non-operation holes on the workpiece to be distributed, and prevent impurities such as iron filings from entering the inside of the mechanical equipment through the holes and causing damage to the equipment.

[0033] In order to further improve the sealing effect and the firmness of installation, a sealing ring 23 is provided on the outer periphery of the second cover accessory 22 in this embodiment. The sealing ring is made of an elastic material, such as rubber or silica gel, to ensure that it can be closely attached to the inner wall surface of the workpiece hole during the installation process to form an effective seal. At the same time, a sealing ring installation groove 24 is also provided on the outer periphery of the second cover accessory 22 for fixing and installing the sealing ring 23 to ensure that it will not fall off or shift during the working process.

[0034] In order to facilitate the fixation of the distribution protection tooling on the workpiece, a second threaded hole 25 is provided at the bottom of the second cover plate 22 in this embodiment. During installation, bolts or other fasteners can be used to pass through the threaded hole to tightly connect the protection tooling with the workpiece.

[0035] The specific implementation process of this embodiment can be summarized as follows: Before the distribution operation starts, first place the distribution protection tooling on the workpiece to ensure that the sealing ring on the second cover accessory 22 is closely attached to the inner wall surface of the workpiece. Then, use bolts or other fasteners to pass through the second threaded hole 25 to fix the protection tooling on the workpiece. Next, the distribution operation can be carried out, such as drilling and reaming. During the operation, the generated iron filings will be effectively blocked by the protection tooling and cannot enter the inside of the mechanical equipment. After the operation is completed, remove the protection tooling and perform subsequent processing.

[0036] Embodiment Two: Distribution Protection Tooling for the Bearing End Cover of a Reducer

[0037] As Figures 1 to 6, in view of the special requirements for the pinning operation of the bearing end cover 100 of the speed reducer, this embodiment provides a pinning protection tooling, which includes a first protection tooling 1 and a plurality of second protection toolings 2.

[0038] The first protection tooling 1 is composed of a first cover plate 11 and a first cover pair 12. The first cover plate 11 is designed to be through-shaped, that is, one or more through holes corresponding to the pinning operation area are opened thereon. The first cover pair 12 is connected to one side of the first cover plate 11 and jointly forms a protection barrier with the first cover plate 11. During the pinning operation, the pinning tool can enter the operation area through these through holes.

[0039] To further enhance the sealing effect, this embodiment also circumferentially arranges a first cover pair groove 13 at the end of the first cover pair 12. This groove is used to cooperate with the bearing end cover of the speed reducer and can install additional sealing strips or sealing rings to ensure that the first protection tooling 1 can be firmly installed on the bearing end cover of the speed reducer and no iron filings will enter the interior of the speed reducer through the gap during the pinning operation.

[0040] The design of the second protection tooling 2 is the same as that of the single-piece pinning protection tooling in the first embodiment, that is, it is composed of a second cover plate 21 and a second cover pair 22. During the pinning operation of the bearing end cover of the speed reducer, the second protection tooling 2 is used to protect other shaft holes except the bearing end cover to prevent iron filings from entering these holes.

[0041] The specific implementation process of this embodiment can be summarized as follows: Before the pinning operation of the bearing end cover 100 of the speed reducer starts, first place the first protection tooling 1 on the bearing end cover 100. Then, use bolts or other fasteners to pass through the first threaded hole 14 to fix the first protection tooling 1 on the bearing end cover. Next, install a plurality of second protection toolings 2 on the shaft holes 102 that need to be protected and fix them. After the installation is completed, the pinning operation can be carried out. During the operation, the generated iron filings will be jointly blocked outside the speed reducer by the first protection tooling 1 and the second protection tooling 2, solving the problem that the iron filings generated by drilling and reaming entering the interior of the mechanical equipment will damage the mechanical equipment.
