[0017] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0018] As Figure 1 and 2 shown, the present utility model discloses an installation tool for a cylindrical pin, which includes a front guide sleeve 3, a rear guide sleeve 7, an impact shaft 8 and an impact device. One end of the front guide sleeve 3 is provided with a receiving hole, and the other end is connected to the rear guide sleeve 7. An accommodation cavity is formed inside the front guide sleeve 3 and the rear guide sleeve 7. The receiving hole communicates with the accommodation cavity. The receiving hole is used to accommodate the cylindrical pin 9 to be installed. The output end of the impact device is connected to the impact shaft 8. The impact shaft 8 is movably inserted into the accommodation cavity. A resilient reset member is sleeved on the impact shaft 8. The resilient reset member is used to drive the impact shaft 8 to reset. Among them, the resilient reset member is a compression spring 6. An adsorbing member is installed on the front guide sleeve 3. The adsorbing member is used to adsorb the cylindrical pin 9 in the receiving hole. By means of the adsorbing member, the cylindrical pin 9 is adsorbed in the receiving hole, preventing the cylindrical pin 9 from coming out, ensuring the alignment of the cylindrical pin 9 with the pin hole, and improving the convenience during the installation of the cylindrical pin 9.

[0019] In this embodiment, the impact device is a pneumatic hammer (not shown in the figure). The impact shaft 8 is butted against the pneumatic hammer. The left end of the cylindrical pin 9 is pressed against the pin hole to be installed. Pull the switch of the pneumatic hammer to make the impact shaft 8 impact the cylindrical pin 9, and assemble the cylindrical pin 9 into the pin hole. The operation is simple and can meet the working environment where a knocking hammer cannot be used due to limited space. After the installation of the cylindrical pin 9 is completed, the elastic reset member drives the impact shaft 8 to move backward to its original position.

[0020] In this embodiment, the adsorbing member is an annular magnet 2. The annular magnet 2 is a permanent magnet, and a through hole for the cylindrical pin 9 to pass through is provided at the center of the annular magnet 2. To ensure the smooth installation of the cylindrical pin 9 on the pin hole, the through hole of the annular magnet 2 is in clearance fit with the cylindrical pin 9. The cylindrical pin 9 is adsorbed in the receiving hole by the magnetic force of the annular magnet 2 to prevent the cylindrical pin 9 from coming out, ensure the alignment of the cylindrical pin 9 with the pin hole, and does not affect the impact shaft 8 to impact the cylindrical pin 9 into the pin hole, improving the convenience of operation and reducing the alignment difficulty between the cylindrical pin 9 and the pin hole.

[0021] Furthermore, the annular magnet 2 is installed on the front guide sleeve 3 through a fixing member 1. The fixing member 1 is a nut with a hole. The fixing member 1 is used to fix the annular magnet 2, ensure the firm installation of the annular magnet 2, and prevent foreign objects from being adsorbed on the annular magnet 2, ensuring the magnetic force and cleanliness of the annular magnet 2.

[0022] Optionally, the annular magnet 2 can also be bonded to the end of the front guide sleeve 3, which can also achieve the function of fixing the annular magnet 2.

[0023] In this embodiment, a support washer 5 is installed between the front guide sleeve 3 and the rear guide sleeve 7. A stop is provided on the impact shaft 8, and the elastic reset member is located between the support washer 5 and the stop. Through the cooperation of the support washer 5 and the stop, the elastic reset member is limited, and it is ensured that the impact shaft 8 can be normally reset under the action of the elastic reset member.

[0024] Furthermore, a groove is provided on the impact shaft 8, and two spliced semi-circular washers 4 are installed on the groove. The semi-circular washers 4 are adjacent to the support washer 5. Through the cooperation of the semi-circular washers 4 and the support washer 5, the maximum reset position of the impact shaft 8 is limited to prevent the impact shaft 8 from coming out of the receiving cavity, ensuring the convenience of using the installation tool.

[0025] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
