[0027] The utility model provides a pressing fixture for a pin shaft. By cooperating with each other among a pin shaft fixture assembly, a pressing assembly and a positioning assembly, when an electric pushing link of the pin shaft pressing fixture is damaged, the structure of the entire fixture can be immediately switched, and an operator manually operates the pressing fixture for use in an emergency state. In this way, there is no need to replace the fixture immediately, the use is more flexible, and the normal use of the entire pressing fixture is not affected.

[0028] Example 1

[0029] Figure 1 , Figure 2 , Figure 3 The figure shows the overall structure of a press-in fixture for a pin shaft according to the present invention. Figure 1 , Figure 2 , Figure 3 The main structure of this embodiment includes: a pin fixture assembly, a press-in assembly and a positioning assembly.

[0030] The pin fixture assembly is used in conjunction with the positioning assembly to realize the rotation switching between manual operation and automatic operation. Specifically, the pin fixture assembly includes a pin placement cylinder 11, an L-shaped support rod 12 fixed on the surface of the pin placement cylinder 11, a pin body 13 placed in the pin placement cylinder 11, a first disc 14 fixed on the top of the L-shaped support rod 12, a rotating shaft 15 arranged on the surface of the first disc 14, a second disc 16 arranged on the top of the rotating shaft 15, and a double hook bracket 17 fixed on the surface of the second disc 16;

[0031] A positioning assembly, the positioning assembly includes a first positioning hole 31 opened on the surface of the first disc 14, a second positioning hole 32 arranged directly opposite the first positioning hole 31, and a third positioning hole 33 opened on the surface of the second disc 16;

[0032] In specific use, when the electric push is used, the second positioning hole 32 and the third positioning hole 33 correspond to each other, and the threaded long rod 34 passes through the second positioning hole 32 and the third positioning hole 33 in sequence, and then the nut 35 is tightened, so that the first disc 14 and the second disc 16 can be positioned. When the electric telescopic rod 23 is damaged and needs to be pressed in manually, the user unscrews the nut 35 and then pulls out the threaded long rod 34. At this time, the user rotates the double-hook bracket 17, and the double-hook bracket 17 rotates through the rotating shaft 15, so that the first mounting plate 21 and the second mounting plate 22 can exchange positions with each other. After the position exchange is completed, the first positioning hole 31 and the third positioning hole 33 correspond to each other. At this time, the user uses the threaded long rod 34 to pass through the first positioning hole 31 and the third positioning hole 33, and uses the nut 35 to lock;

[0033] The press-in assembly is used for pressing the pin shaft. Specifically, the press-in assembly includes a first mounting plate 21 fixed to one end of the double hook bracket 17, a second mounting plate 22 fixed to the other end of the double hook bracket 17, an electric telescopic rod 23 arranged on the surface of the first mounting plate 21, a first push plate 24 connected to the end of the electric telescopic rod 23, a through hole 221 opened on the surface of the second mounting plate 22, a long rod 25 passing through the through hole 221, and a second push plate 26 fixed to the end of the long rod 25;

[0034] When using electric pushing, the user places several pin shaft bodies 13 in the pin shaft placing tube 11, and the electric telescopic rod 23 pushes the first push plate 24 into the pin shaft placing tube 11, so that the pin shaft body 13 can be squeezed out of the pin shaft placing tube 11, and the pin shaft placing tube 11 is guided in position to ensure that the pin shaft body 13 is accurately pressed in. When manually pressing in, the user holds the handle 27 and pushes forward, and the long rod 25 moves forward along the through hole 221 until the long rod 25 drives the second push plate 26 to be pushed into the pin shaft placing tube 11, and the pin shaft body 13 is pressed into the part.

[0035] Working principle: When the electric push is used, the second positioning hole 32 and the third positioning hole 33 correspond to each other, and the threaded long rod 34 passes through the second positioning hole 32 and the third positioning hole 33 in sequence, and then the nut 35 is tightened, so that the first disc 14 and the second disc 16 can be positioned. At this time, the user places a plurality of pin shaft bodies 13 in the pin shaft placement tube 11, and the electric telescopic rod 23 pushes the first push plate 24 into the pin shaft placement tube 11, so that the pin shaft body 13 can be squeezed out of the pin shaft placement tube 11, and the pin shaft placement tube 11 guides the position to ensure that the pin shaft body 13 is accurately pressed in. When the electric telescopic rod 23 is damaged, the user unscrews the nut 35, and then tightens the threaded long rod The rod 34 is pulled out, and the user rotates the double-hook bracket 17 at this time, and the double-hook bracket 17 rotates through the rotating shaft 15, so that the first mounting plate 21 and the second mounting plate 22 can exchange positions with each other. After the position exchange is completed, the first positioning hole 31 and the third positioning hole 33 correspond to each other. At this time, the user uses the threaded long rod 34 to pass through the first positioning hole 31 and the third positioning hole 33, and uses the nut 35 to lock it. At this time, the user holds the handle 27 and pushes it forward, and the long rod 25 moves forward along the through hole 221 until the long rod 25 drives the second push plate 26 to be pushed into the pin shaft placement tube 11, and the pin shaft body 13 is pressed into the part. Such a structural design of automatic and manual switching has strong applicability and is convenient for flexible use.

[0036] Example 2

[0037] Please refer to Figure 4 Through the display component, the user can quickly determine the pressing position of the pin through the annular aperture, which greatly reduces the alignment time of the operator and facilitates the quick pressing of the pin into the corresponding part;

[0038] Specifically, it also includes a display assembly, which includes an annular disk 41 fixed to the end of the pin placement tube 11, an infrared ray lamp 42 arranged on the surface of the annular disk 41, and a circular hole 43 opened on the surface of the annular disk 41;

[0039] During specific use, a plurality of infrared ray lamps 42 are distributed in a ring shape, so that the infrared ray lamps 42 distributed in a ring shape illuminate an annular aperture. At this time, the user can quickly determine the pressed position of the pin shaft through the aperture, so that the operator can quickly lock the pressed position.

[0040] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
