[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present application embodiment discloses a portable tool for loading and unloading pins. Figure 1 and Figure 2 A portable tool for loading and unloading pins includes a pressing mechanism and a reaction frame, wherein the pressing mechanism includes a push rod 9 and a power assembly, wherein the push rod 9 is aligned and abutted against the pin 14, and the power assembly drives the push rod 9 to press the pin 14, thereby realizing the loading and unloading of the pin 14 on the part 13. In order to prevent the part 13 from moving in a direction away from the push rod 9 when the push rod 9 presses the pin 14, so that the loading and unloading of the pin 14 on the part 13 can be completed conveniently and quickly, it is necessary to position the part 13 and the push rod 9 with the help of the reaction frame; the reaction frame includes a mounting plate 1, a support plate 2 and a connecting rod 3, wherein the mounting plate 1 and the support plate 2 are connected by the connecting rod 3, and the mounting plate 1 and the support plate 2 are both movably sleeved on the connecting rod 3 along the length direction of the connecting rod 3, and a positioning assembly for limiting the sliding of the mounting plate 1 and the support plate 2 in a direction away from each other is provided on the connecting rod 3. An operating space for installing and removing the pins 14 of the parts 13 is formed between the mounting plate 1 and the supporting plate 2 . The push rod 9 is located in the operating space and is movably mounted on the mounting plate 1 in a direction perpendicular to the supporting plate 2 .

[0026] When it is necessary to install the pin 14 on the part 13, the maximum distance between the support plate 2 and the mounting plate 1 can be adaptively adjusted according to the length of the pin 14 and the installation depth of the pin 14 in the mounting hole of the part 13, and the positioning assembly can be used to limit the positions of the mounting plate 1 and the support plate 2 on the connecting rod 3; then the part 13 is placed in the operating space and abutted against the support plate 2; then the pin 14 is inserted between the part 13 and the push rod 9, and the position of the pin 14 is adjusted so that the pin 14 is aligned with the mounting hole on the part 13; then the power assembly is started, and the power assembly drives the push rod 9 to push the pin 14 away from the mounting plate 1. At this time, the mounting plate 1 can provide reaction force support for the push rod 9, so that the pin 14 is quickly pressed into the mounting hole of the part 13 under the pressure of the push rod 9.

[0027] Considering that when the pin 14 is ejected from the part 13 by using the ejector 9, a retreat space 5 for the pin 14 to exit needs to be provided on the support plate 2, Figure 1 and Figure 2 , a through hole is formed on the support plate 2 at the position corresponding to the push rod 9, which is used as a retreat space 5 for the pin 14 to withdraw, and the aperture of the through hole is not less than the diameter of the pin 14. When the pin 14 on the part 13 needs to be removed from the part 13, the maximum distance between the support plate 2 and the mounting plate 1 can be adaptively adjusted according to the length of the pin 14, and the position of the mounting plate 1 and the support plate 2 on the connecting rod 3 can be limited by using the positioning assembly; then the part 13 is placed in the operating space and abutted against the support plate 2, and the position of the part 13 is adjusted at the same time so that the pin 14 is aligned with the retreat space 5; then the power assembly is started, and the power assembly drives the push rod 9 to push the pin 14 away from the mounting plate 1, so that under the pressure of the push rod 9, the pin 14 can smoothly withdraw from the mounting hole of the part 13 and enter the retreat space 5, thereby quickly removing the pin 14 from the part 13.

[0028] Before the push rod 9 is used to push the pin 14, the part 13 is prone to relative slippage with the support plate 2, so that the push rod 9 cannot be quickly aligned with the pin 14, so Figure 1 and Figure 2The reaction frame also includes a positioning plate 15, which is located in the operating space and is slidably installed on the connecting rod 3 along the length direction of the connecting rod 3. The connecting rod 3 is provided with a stopper 16 for limiting the movement of the positioning plate 15 in the direction away from the support plate 2. When the pin 14 is installed and removed from the part 13, one side of the part 13 is firstly abutted against the support plate 2, and then the position of the positioning plate 15 on the connecting rod 3 is adjusted so that the positioning plate 15 abuts against the other side of the part 13, and finally the stopper 16 is used to limit the movement of the positioning plate 15 in the direction away from the support plate 2. At this time, the part 13 is stably supported between the positioning plate 15 and the support plate 2. Since the mounting plate 1 is located on the side of the positioning plate 15 away from the part 13, an operating hole 17 for the push rod 9 to movably penetrate is also opened on the positioning plate 15, so that when the positioning plate 15 and the support plate 2 are respectively pressed against the two sides of the part 13, the power assembly can drive the push rod 9 to penetrate the operating hole 17 and quickly press the pin 14 to install and remove it on the part 13.

[0029] For the settings of the positioning components, refer to Figure 1 and Figure 2 , the corresponding positions of the mounting plate 1 and the support plate 2 are penetrated with a socket for the connecting rod 3 to pass through, and the connecting rod 3 is movably passed through the sockets on the mounting plate 1 and the support plate 2 in turn. The positioning assembly includes a threaded rod 6 located at both ends of the connecting rod 3 and a positioning nut 7 threadedly sleeved on the threaded rod 6. By driving the positioning nut 7 to rotate on the threaded rod 6 according to the length of the pin 14 and the depth of the mounting hole on the part 13, the distance between the two positioning nuts 7 on the connecting rod 3 can be quickly adjusted. When the pin 14 is installed and removed from the part 13, the power assembly drives the push rod 9 to press the pin 14, the mounting plate 1 provides a reaction force support for the push rod 9, and the part 13 is pressed against the support plate 2. At this time, the two positioning nuts 7 are respectively in contact with the surfaces of the mounting plate 1 and the support plate 2 on the opposite side, ensuring that the push rod 9 can smoothly push the pin 14 out of the mounting hole of the part 13 or ensure that the push rod 9 can smoothly push the pin 14 into the mounting hole of the part 13 to a suitable depth. As for the setting of the limit member 16, in the embodiment of the present application, the limit member 16 is set to be a limit nut identical to the positioning nut 7, and the connecting rod 3 is also provided with an external thread identical to the threaded rod 6, and the limit nut is threadedly sleeved on the connecting rod 3 and is located between the mounting plate 1 and the positioning plate 15, thereby preventing the positioning plate 15 from sliding away from the support plate 2.

[0030] Since the support plate 2 and the mounting plate 1 are both subjected to a large force when the tool is used to install and remove the pin 14 of the part 13, in order to stably and quickly complete the installation and removal of the pin 14, refer to Figure 1 and Figure 2There are two groups of connecting rods 3, and the two groups of connecting rods 3 are respectively located on both sides of the top rod 9, so that the support plate 2 and the mounting plate 1 can stably support the part 13 and the top rod 9 under the connection of the two groups of connecting rods 3. Considering the lightweight design of the tool, each group of connecting rods 3 is only one, which greatly reduces the weight of the tool and makes the tool convenient to carry.

[0031] In order to be able to quickly adjust the distance between the two positioning nuts 7 on the two connecting rods 3 to the same state, a number of scales are correspondingly set on the two connecting rods 3, so that when adjusting the positioning nuts 7 on both ends of the two connecting rods 3, the scales can be referred to to quickly adjust the distance between the two sets of positioning nuts 7 to the same, ensuring that when the support plate 2 and the mounting plate 1 support the part 13 and the top rod 9, the support plate 2 and the mounting plate 1 are both stably abutted by the two positioning nuts 7, ensuring that the connecting rod 3 is only subjected to axial force, effectively reducing the risk of the connecting rod 3 being broken.

[0032] Reference Figure 1 and Figure 2 The power assembly includes a hydraulic cylinder 10 located in the operating space and fixed on the mounting plate 1, a pump body 12 located outside the operating space, and a hose 11 for connecting the pump body 12 with the hydraulic cylinder 10. A support plate 4 for supporting the hydraulic cylinder 10 is fixedly mounted on the mounting plate 1. The push rod 9 is connected to the output end of the hydraulic cylinder 10, so that when loading and removing the pin 14 of the part 13, it is only necessary to operate the pump body 12 outside the operating space. The pump body 12 drives the hydraulic cylinder 10 to push the push rod 9 to press the pin 14 through the hose 11, thereby conveniently and quickly completing the loading and removing of the pin 14 of the part 13.

[0033] Since the hose 11 can swing in any direction, if the part 13 is a flat plate structure and the pin 14 on the part 13 needs to be removed, in order to improve the convenience of operation, the hose 11 can be moved in any direction. Figure 1 The reaction frame in the figure is rotated 90 degrees so that the retreat space 5 faces the ground, and the part 13 is placed above the support plate 2. At this time, the pin 14 on the part 13 is in a vertical state. In order to allow the pin 14 to be pushed out smoothly toward the ground, refer to Figure 1 and Figure 2, a pad 8 is fixedly mounted on the surface of the side of the support plate 2 away from the mounting plate 1. When in use, the position of the positioning nut 7 on the threaded rod 6 is adjusted so that when the support plate 2 abuts against the positioning nut 7 and the pad 8 contacts the ground, the end of the threaded rod 6 does not contact the ground, effectively reducing the risk of the threaded rod 6 being crushed. The pad 8 can set up the reaction frame above the ground, so that the retreat space 5 is exposed, and the distance from the ground to the support plate 2 is greater than the length of the pin 14, so that the pin 14 can be quickly and smoothly removed from the plate-shaped part 13. Considering that when the tool is used to install and remove the pin 14 from the part 13, both the support plate 2 and the mounting plate 1 are subjected to a large force, in order to enable the pad 8 to stably support the reaction frame, in the embodiment of the present application, two groups of pads 8 are provided, each group of pads 8 is provided with one, and the two groups of pads 8 are respectively located on both sides of the through hole.

[0034] The implementation principle of a portable tool for loading and removing pins in an embodiment of the present application is: according to the length of the pin 14 and the depth of the mounting hole on the part 13, refer to the scale on the connecting rod 3, drive the positioning nut 7 to rotate on the threaded rod 6, and quickly adjust the distance between the two positioning nuts 7 on the connecting rod 3, thereby completing the adjustment of the maximum distance between the mounting plate 1 and the support plate 2. When it is necessary to install the pin 14 on the part 13, the part 13 can be placed in the operating space first and one side of the part 13 can be abutted against the support plate 2; then the position of the positioning plate 15 on the connecting rod 3 is adjusted so that the positioning plate 15 abuts against the other side of the part 13, and at the same time, the limiter 16 is used to limit the movement of the positioning plate 15 away from the support plate 2. At this time, the part 13 is stably held between the positioning plate 15 and the support plate 2; then the pin 14 is placed between the part 13 and the push rod 9, and the position of the pin 14 is adjusted so that the pin 14 is aligned with the mounting hole on the part 13; then the pump body 12 is started, and the pump body 12 drives the hydraulic cylinder 10 to push the push rod 9 to press the pin 14 through the hose 11, so that the pin 14 passes through the operating hole 17 on the mounting plate 1 under the pressure of the push rod 9, and the pin 14 is quickly pressed into the mounting hole of the part 13.

[0035] When it is necessary to remove the pin 14 on the part 13 from the part 13, the part 13 can be placed in the operating space first and abutted against the support plate 2, and the position of the part 13 can be adjusted at the same time so that the pin 14 is aligned with the retreat space 5; then the position of the positioning plate 15 on the connecting rod 3 is adjusted so that the positioning plate 15 abuts against the other side of the part 13, and at the same time, the limiter 16 is used to limit the movement of the positioning plate 15 away from the support plate 2. At this time, the part 13 is stably held between the positioning plate 15 and the support plate 2; then the pump body 12 is started, and the pump body 12 drives the hydraulic cylinder 10 through the hose 11 to push the push rod 9 through the operating hole 17 to press the pin 14, so that the pin 14 can smoothly withdraw from the mounting hole of the part 13 and enter the retreat space 5, thereby realizing the rapid removal of the pin 14 from the part 13.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
