Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery equipment accessories, and particularly relates to an elastic pin installation tool. Background Art

[0002] Spring pins are widely used in the mechanical industry, mainly for positioning, connecting, and fixing between components. In agricultural machinery equipment (such as tractors), spring pins are often used to connect components.

[0003] Currently, the most common method in the industry is to install spring pins using a pure manual installation method, that is, the worker needs to hold the spring pin with pliers in one hand and use a hammer to strike the spring pin until it is installed in place. This method is low-cost and simple. However, during use, on the one hand, it may cause the spring pin to be knocked flying, posing a potential safety hazard; on the other hand, the positioning and guiding using pliers are not accurate enough, and it is easy to bend the spring pin when striking it, resulting in low assembly efficiency.

[0004] Based on this, it is necessary to develop an elastic pin installation tool to overcome the above technical problems. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an elastic pin installation tool, which effectively overcomes the defects of the prior art.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] An elastic pin installation tool includes a columnar main body. One end of the main body is provided with a connecting section with a gradually decreasing cross-sectional area, and a guiding groove for accommodating the elastic pin is opened at the end of the connecting section.

[0008] The beneficial effect of the utility model is that the structure design is simple and reasonable. It can fix the elastic pin through the guiding groove for guiding assembly. During the operation process, it can avoid the elastic pin being knocked flying, protect the operators, reduce safety hazards, and improve assembly efficiency. At the same time, the design of the connecting section is particularly suitable for operating in narrow spaces.

[0009] On the basis of the above technical solution, the utility model can be further improved as follows.

[0010] Further, the main body is a cylinder.

[0011] The beneficial effect of adopting the above further technical solution is that the appearance is standard and beautiful, and the force-bearing is good.

[0012] Further, the connecting section is a conical section coaxially arranged with the main body.

[0013] The beneficial effect of adopting the above further technical solution is that the design of the tapered section enables the elastic pin to take advantage of the small diameter of the tip to extend into a narrow space for installation, thereby effectively improving the operating efficiency.

[0014] Furthermore, a positioning column is coaxially provided at one end of the connecting section away from the main body, and the guide groove is provided at the end of the positioning column.

[0015] The beneficial effect of adopting the above further technical solution is that the design of the positioning column has a smaller diameter, which is particularly suitable for entering a relatively narrow space, making it more convenient and smoother for the elastic pin to be installed in a deeper and narrow space.

[0016] Furthermore, two opposite sides of the positioning column are provided with planes extending along the length direction thereof and parallel to each other.

[0017] The beneficial effect of adopting the above further technical solution is that the design of the planes on both sides of the positioning column can adapt to the shape of the fork, which is particularly suitable for the installation of elastic pins in the narrow space inside the fork, thereby improving the installation efficiency in this operation scenario.

[0018] Furthermore, a striking portion is provided at the other end of the main body.

[0019] The beneficial effect of adopting the above further technical solution is that the design of the striking part makes it convenient to strike the entire tool with a hammer or other tool.

[0020] Furthermore, the striking part is a flat member.

[0021] The beneficial effect of adopting the above-mentioned further technical solution is that the flat design of the striking part greatly increases its area, that is, increases the striking area, which can prevent accidental operation and injury to the hand when installing the elastic pin, thereby reducing safety hazards.

[0022] Furthermore, the striking part is a flat cylindrical component.

[0023] The beneficial effect of adopting the above further technical solution is that the striking part has a standard shape design and is coaxially arranged with the main body, so that the striking force can be well transmitted to the elastic pin.

[0024] Furthermore, a magnetic block is embedded in the bottom of the guide groove.

[0025] The beneficial effect of adopting the above further technical solution is that the design of the magnetic block can obtain a certain degree of adsorption after the elastic pin is embedded in the guide groove, thereby preventing the elastic pin from falling off during the process of moving the entire tool to extend it into the target position.

[0026] Furthermore, a pin hole perpendicular to the main body is provided on the side surface of the other end of the main body, and a straightening rod is detachably inserted into the pin hole.

[0027] The beneficial effects of adopting the above further technical solution are as follows: The design of the centering rod is very reasonable, and it can use the centering rod to achieve the centering of the centering rod and the elastic pin at a distance slightly farther from the main body, which is beneficial to subsequent knocking and avoids the problem that the operator's hand may be accidentally hit during the knocking process.

[0034] The principles and features of the present utility model will be described below in conjunction with the drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0035] Embodiment: As shown in Figure 1 and 2 The elastic pin installation tool of this embodiment includes a columnar main body 1. One end of the main body 1 is provided with a connection section 11 with a gradually decreasing cross-sectional area, and a guide groove 12 for accommodating the elastic pin is opened at the end of the connection section 11.

[0036] Before assembling the elastic pin in the elastic pin installation tool of this embodiment, the elastic pin (partially) is embedded in the guide groove 12, and then the exposed part of the elastic pin is embedded in the corresponding pin hole. Then, the main body 1 is centered, and the other end of the main body 1 is struck with a tool such as a hammer, so as to drive the elastic pin into the corresponding pin hole to complete the assembly between components. Due to the design of the guide groove 12, the elastic pin is positioned before being installed. During the striking process, the elastic pin is partially kept in the guide groove 12, and there will be no phenomenon that the elastic pin is knocked flying, effectively protecting the operator, reducing potential safety hazards, and improving the assembly efficiency.

[0037] In addition, the entire tool adopts a columnar main body 1, which is a slender member in itself, and is then transitioned through a connecting section 11 with a smaller cross-sectional area. A guiding groove 12 is provided at the end of the connecting section 11. Such a structural design enables the connecting section 11 to carry an elastic pin to perform the impact installation operation of the elastic pin in a narrow space, improving the drawback that it is laborious and time-consuming to install the elastic pin in a narrow space. The entire tool can replace the pure manual installation of the elastic pin, reducing the potential safety accident hazards. At the same time, it is applicable to the elastic pin assembly operations in narrow spaces such as fork levers, improving the operation efficiency.

[0038] In this embodiment, the above-mentioned main body 1 adopts a cylinder, which has a regular shape and stable impact force transmission.

[0039] As a preferred implementation manner, the above-mentioned connecting section 11 is a conical section coaxially arranged with the above-mentioned main body 1.

[0040] In the above-mentioned implementation scheme, the connecting section 11 is designed as a cone, which can be well connected to the main body 1 and is also beneficial to the impact installation of the elastic pin in a narrow space.

[0041] As a preferred implementation manner, a positioning post 13 is coaxially provided at one end of the above-mentioned connecting section 11 away from the above-mentioned main body 1, and the guiding groove 12 is opened at the end of the above-mentioned positioning post 13.

[0042] In the above-mentioned implementation scheme, the design of the positioning post 13 has a smaller diameter or cross-sectional area compared to the connecting section 11, and can perform the impact installation operation of the elastic pin for a narrower space.

[0043] As a preferred implementation manner, two parallel planes (designated as a in the figure) extending along its length direction are provided on opposite sides of the above-mentioned positioning post 13.

[0044] In the above-mentioned implementation scheme, taking the installation of the elastic pin in a tractor as an example, the elastic pin may be installed in the fork lever. Therefore, the opposite sides of the positioning post 13 are set as a parallel plane structure, and this plane structure is adapted to the installation position and shape of the fork lever, and can better extend into the corresponding position of the fork lever to perform the impact installation operation of the elastic pin.

[0045] As a preferred implementation manner, a striking part 14 is provided at the other end of the above-mentioned main body 1.

[0046] In the above-mentioned implementation scheme, this design facilitates the operator to strike the striking part 14 with tools such as a hammer, so as to transmit the striking force to the elastic pin through the entire tool and complete the good installation of the elastic pin.

[0047] As a preferred implementation manner, the above-mentioned striking part 14 is a flat member.

[0048] In the above embodiment, the striking portion 14 adopts a flat structural design, and its area is larger than the cross-sectional area of the main body 1, thereby increasing the striking area, preventing accidental operation and injuring the hand when installing the elastic pin, and reducing safety hazards.

[0049] In this embodiment, the striking portion 14 is a flat cylindrical component, and can be coaxially distributed with the cylindrical main body 1 .

[0050] As a preferred embodiment, Figure 3 As shown, a magnetic block 121 is embedded in the bottom of the guide groove 12 .

[0051] In the above implementation scheme, the magnetic block 121 is embedded in the bottom of the guide groove 12. After the elastic pin is installed in the guide groove 12, the magnetic block 121 can produce a certain adsorption with the elastic pin (marrite or ferrite stainless steel elastic pin). In the process of moving the entire tool to make the elastic pin enter the target position, the elastic pin will not easily fall out of the guide groove 12, which is beneficial to the subsequent alignment and installation operations.

[0052] As a preferred embodiment, Figure 4 As shown, a pin hole perpendicular to the main body 1 is opened on the side surface of the other end thereof, and a straightening rod 15 is detachably inserted into the pin hole.

[0053] In the above implementation scheme, since the main body 1 needs to be straightened during the operation to ensure that the elastic pin can enter the target pin hole in the correct direction and standard posture, and since there is a knocking operation in the entire operation process, there may be a phenomenon of hitting the operator's hand due to misoperation. Therefore, a slender straightening rod 15 is vertically inserted into the pin hole on the side of the other end of the main body 1, and the straightening rod 15 is used to straighten the main body 1. During the knocking process, the probability of knocking on the operator's hand due to misoperation can be greatly reduced, thereby improving the safety of the operation to a certain extent.

[0054] Of course, the other end of the straightening rod 15 can be provided with a handle, which is convenient for the operator to hold to straighten the entire tool. The handle can be designed as a ring, which is convenient for gripping, or it can be set to a rod shape with an anti-slip structure on the surface.

[0055] It is particularly necessary to explain that in the elastic pin installation tool of this embodiment, the main body 1, the connecting section 11, the positioning column 13 and the striking part 14 are all integrally cast components, and the structural strength is relatively high.
