Description

Technical Field

[0001] The utility model relates to the technical field of a pin shaft seat, in particular to a pin shaft seat installation tool. Background Art

[0002] During the manufacturing and maintenance of high-speed EMUs, the installation of pin seats is a key process, and its accuracy directly affects the operating stability and safety of the EMU. Pin seats are usually used to connect or position mechanical parts to ensure precise alignment and motion transmission between them. To achieve this goal, the pins must be accurately installed in the pin seats and effectively limited and fixed to prevent displacement or loosening during use.

[0003] After the pin is passed through the pin seat, the traditional pin seat installation tool needs to install the limit piece again to position and fix the pin. Since the process of assembling the limit piece is cumbersome for the staff, the installation process is not convenient, which increases the installation time and reduces the efficiency of the pin installation. Therefore, we propose a pin seat installation tool. Utility Model Content

The bottom of the pin seat is connected to a connecting plate, and a lifting mechanism is arranged on the bottom of the connecting plate. The lifting mechanism is used to adjust the height of the pin shaft, and the lifting mechanism is connected to a mounting plate.

An axial hole is opened on the front of the pin seat 1, and a pin shaft 4 is arranged inside the axial hole. The two limiting mechanisms 2 are used to limit the pin shaft 4, and the two pressing mechanisms 3 are used to squeeze the two limiting mechanisms 2 to release the limitation of the pin shaft 4.

The lifting mechanism 6 is used to adjust the height of the pin shaft 4, and the lifting mechanism 6 is connected with a mounting plate 7.

[0024] Specifically, placing the pin shaft 4 into the shaft hole will squeeze the two limiting mechanisms 2 to shrink. When the pin shaft 4 is no longer squeezing the two limiting mechanisms 2, the two limiting mechanisms 2 will reset to limit the front side of the pin shaft 4 to complete the installation. Pressing the two pressing mechanisms 3 will release the two limiting mechanisms 2 from limiting the pin shaft 4. At this time, the pin shaft 4 can be taken out from the inside of the shaft hole to complete the disassembly.

[0025] Embodiment 2:

[0026] See also Figures 2-3 In the embodiment of the utility model, a pin seat installation tool is provided, the limiting mechanism 2 includes a connecting block 201, a slot body 202, a connecting block 203 and a telescopic rod 204, the connecting block 201 is connected to the front of the pin seat 1, the slot body 202 is arranged inside the connecting block 201, the connecting block 203 is connected to one side of the inner wall of the slot body 202, and the telescopic rod 204 is connected to one side of the connecting block 203, the limiting mechanism 2 also includes a limiting block 205, a slot 206 and a first spring 207, the limiting block 205 is connected to one end of the telescopic rod 204, and the limiting block 205 extends to the outside of the slot body 202, and the slot 206 is arranged on the positive side of the limiting block 205.

[0027] Specifically, when the pin shaft 4 is inserted into the shaft hole, the limit block 205 will be squeezed to move into the groove body 202. At the same time, the telescopic rod 204 will contract and the first spring 207 will be compressed. When the front side of the pin shaft 4 is located at the back side of the limit block 205, the limit block 205 will no longer be squeezed. The first spring 207 will be reset and the telescopic rod 204 will extend to drive the limit block 205 to the side of the connecting block 201 to limit the front side of the pin shaft 4 to complete the installation of the pin shaft 4.

The limit block 205 moves toward the inside of the groove body 202 to release the limit on the pin shaft 4 and complete the disassembly of the pin shaft 4, thereby improving the installation efficiency.

[0028] Embodiment 3:

[0029] See also Figures 1 to 4 In the embodiment of the utility model, a pin shaft seat installation tool is provided, and the lifting mechanism 6 includes two vertical plates 601, a threaded rod 602, a turning handle 603 and two guide rods 604. The two vertical plates 601 are connected to the top of the mounting plate 7, the threaded rod 602 is rotatably connected between the two vertical plates 601, the turning handle 603 is rotatably connected to the front of one of the vertical plates 601, and one end of the turning handle 603 extends to the back of one of the vertical plates 601 and is connected to one end of the threaded rod 602, the two guide rods 604 are fixedly connected between the two vertical plates 601, and the two guide rods 604 are located on both sides of the threaded rod 602, and the lifting mechanism 6 also includes two transverse plates 605, two first hinge seats 606, a second hinge seat 607 and two support shafts 608. The two transverse plates 605 are both threadedly connected to the outer surface of the threaded rod 602, and the two transverse plates 605 are both slidably connected to the outer surfaces of the two guide rods 604. The two first hinge seats 606 are respectively connected to the tops of the two transverse plates 605, and the second hinge seat 607 is connected to the bottom of the connecting plate 5. The two support shafts 608 are both hinged inside the second hinge seat 607, and the other ends of the two support shafts 608 are respectively hinged to the insides of the two first hinge seats 606. Two mounting holes are provided on the top of the mounting plate 7.

[0030] Specifically, rotating the handle 603 drives the threaded rod 602 to rotate between the two vertical plates 601, so that the two horizontal plates 605 move closer to each other on the outer surfaces of the threaded rod 602 and the two guide rods 604 and drive the two support shafts 608 to rotate in a ring shape through the two first hinge seats 606, so that the other ends of the two support shafts 608 support the connecting plate 5 through the second hinge seat 607, thereby completing the adjustment of the height of the pin seat 1 to avoid the error distance between the pin shaft 4 and the support. The two mounting holes can be set to cooperate with the bolts to fix the mounting plate 7.

[0031] The working principle of the utility model is as follows: the mounting plate 7 is fixed on the support through the two mounting holes, and when the pin shaft 4 is inserted into the interior of the shaft hole, one end of the pin shaft 4 will squeeze the limit block 205 and move toward the interior of the slot body 202, so that the telescopic rod 204 will be contracted, and the first spring 207 will be compressed. When the front side of the pin shaft 4 is located at the back side of the limit block 205, the limit block 205 will no longer be squeezed. At this time, the first spring 207 will be reset and the telescopic rod 204 will extend to drive the limit block 205 to one side of the connecting block 201 to limit the front side of the pin shaft 4, thereby completing the installation of the pin shaft 4. By pressing the round handle 303, the round handle 303 drives the sliding rod 301 to slide on the front side of the connecting block 201 toward the interior of the slot body 202, and at the same time the second spring 304 will be compressed. And the extrusion block 302 will be inserted into the internal pressure limit block 205 of the card slot 206 and move toward the inside of the slot body 202 to release the limit on the pin shaft 4. At this time, the pin shaft 4 can be disassembled. When the height of the pin seat 1 needs to be adjusted after the mounting plate 7 is fixed, the staff will turn the handle 603. When the handle 603 is turned, it drives the threaded rod 602 to rotate between the two vertical plates 601, so that the two horizontal plates 605 can move on the outer surface of the threaded rod 602 and slide on the outer surfaces of the two guide rods 604 to approach each other. When the two horizontal plates 605 approach each other, the two support shafts 608 are driven to rotate in a ring shape through the two first hinge seats 606, so that the other ends of the two support shafts 608 support the connecting plate 5 through the second hinge seat 607, thereby completing the adjustment of the height of the pin seat 1.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
