Description

Technical Field

[0001] The utility model relates to the field of rail vehicle door installation tools, in particular to a tool used for disassembling and installing a stabilizer gear pin shaft. Background Art

[0002] The stabilizer assembly of the CRH1A high-speed vehicle uses a gear transmission mode, and the gear and the transmission shaft are fixed with double elastic cylindrical pins. The current structure has the problem of the gear being installed and removed unchanged.

[0003] During installation, one person holds the gear and drive shaft while another hammers the pins into the gear and drive shaft holes. Because the gears and drive shafts are not restrained, the double-elastic pins can easily misalign and deform during installation. This reduces efficiency, and because the gears are made of copper, there's a risk of accidentally hitting them with the hammer, causing deformation. This poses a significant risk to the stabilizer gears in subsequent use.

[0004] Therefore, it is necessary to develop a new type of tooling for disassembly and installation of the stabilizer gear pin to overcome the above problems. Utility Model Content

[0005] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, the utility model provides a tool for disassembling and installing the stabilizer gear pin shaft, which solves the problem of difficulty in installing the stabilizer gear and deformation of the gear caused by hitting the elastic cylindrical pin with a hammer.

[0006] Technical solution: The utility model is a tool for disassembling and installing a stabilizer gear pin shaft, which is characterized by comprising a tool body, a gear positioning block for positioning the stabilizer gear on the left side of the tool body, a guide block for installing an elastic cylindrical pin in the middle of the tool body, and a mounting bracket for fixing a hydraulic pump on the right side of the tool body.

[0007] Wherein, the stabilizer gear and the stabilizer transmission shaft are connected and fixed by an elastic cylindrical pin.

[0008] Wherein, the elastic cylindrical pin is installed in the guide block, and the elastic cylindrical pin is installed in the mounting hole of the stabilizer gear and the stabilizer transmission shaft along the guide block.

[0009] Wherein, the hydraulic pump is installed in the mounting frame and fixed by screws.

[0010] Wherein, a push rod positioning sleeve is provided on the top of the hydraulic pump, and the ejector push rod is installed in the push rod positioning sleeve.

[0011] Wherein, the ejector rod, the elastic cylindrical pin and the center hole of the stabilizer gear are in a straight line.

[0012] Wherein, a positioning pin is inserted into the center hole of the stabilizer gear and the stabilizer transmission shaft.

[0013] Beneficial Effects: Compared with existing technologies, this invention offers the following significant advantages: It effectively positions the gears during removal and installation, enabling quick and efficient removal and installation of stabilizer gears. The tooling, combined with a hydraulic pump, ensures that the gears are not deformed by impact during installation of the elastic cylindrical pins. The hydraulic pump replaces manual hammering, reducing noise and optimizing the working environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1-4As shown, 1 is an elastic cylindrical pin, 2 is an ejector rod, 3 is a stabilizer gear, 4 is a push rod locating sleeve, 5 is a tooling body (stabilizer elastic cylindrical pin installation / removal tooling body), 6 is a locating pin, and 7 is a hydraulic pump. The left side of the stabilizer elastic cylindrical pin installation / removal tooling body 5 is a gear locating block, which is used to locate the stabilizer gear 3 during removal or installation, fix its position, and provide a force-bearing surface when the elastic cylindrical pin 1 is installed. The middle of the tooling body 5 is a guide block for the elastic cylindrical pin 1, which is used to guide the elastic cylindrical pin 1 during installation, so that it can be installed in the predetermined direction into the mounting hole of the gear and the drive shaft. The right side of the tooling body 5 is a hydraulic pump mounting bracket, which is used to fix the hydraulic pump 7.

[0026] like Figure 5 As shown, the stabilizer gear 3 and the stabilizer transmission shaft need to be connected and fixed by an elastic cylindrical pin 1.

[0027] like Figure 6 As shown, before installing the stabilizer gear 3, install the elastic cylindrical pin 1 into the elastic cylindrical pin guide block in the middle of the tooling body 5, install the hydraulic pump 7 into the bracket on the right side of the tooling body 5 and fix it with screws, fix the push rod positioning sleeve 4 on the top of the hydraulic pump 7, and install the ejector push rod 2 into the push rod positioning sleeve 4 so that the ejector push rod 2, the elastic cylindrical pin 1 and the gear center hole are in a straight line.

[0028] like Figure 7 As shown, place the stabilizer gear 3 and the stabilizer transmission shaft in the corresponding positions of the tooling body 5, and insert the positioning pin 6 on the left side into the center holes of the gear and the transmission shaft to ensure that the center holes of the gear and the gear transmission shaft will not be displaced during the installation process of the elastic cylindrical pin 1.

[0029] like Figure 8 As shown, start the hydraulic pump 7 and use the ejector push rod 2 to press the elastic cylindrical pin 1 into the center hole of the gear and the transmission shaft. Use the push rod to press the elastic cylindrical pin 1 into the center hole of the gear and the transmission shaft. Use a short push rod in the first section. After the elastic cylindrical pin 1 is installed into the gear through the positioning block, release the hydraulic pump 7 and replace it with a long push rod. Restart the hydraulic pump 7 to push the elastic cylindrical pin 1 to the required position. At the same time, the positioning pin 6 is naturally ejected from the left side of the tooling body 5. Remove the positioning pin 6, release the hydraulic pump 7 and withdraw the push rod, completing the installation of the stabilizer gear 3.

[0030] like Figure 9 As shown, replace the disassembly pin push rod 2, place the stabilizer gear 3 to be disassembled in the corresponding position of the tooling body 5, fix the push rod positioning sleeve 4 on the top of the hydraulic pump 7, and install the long push rod into the push rod positioning sleeve 4. Start the hydraulic pump 7, and push the elastic cylindrical pin 1 out of the center hole of the gear and the transmission shaft to complete the gear disassembly.
