An upper pull leg nested between the retaining ring and the lower pull leg is also provided.

[0003] The existing gear disassembly fixture requires disassembly after disassembly; otherwise, the disassembled workpiece cannot be hoisted. Depending on the height of the disassembled workpiece, a large number of shims and nuts are required to meet the assembly requirements of the fixture. Different specifications of disassembly fixture plates need to be selected according to the diameter of the workpiece. Therefore, we have made improvements and proposed a gear disassembly fixture. Utility Model Content

[0004] The main purpose of this utility model is to provide a gear disassembly fixture, which can effectively solve the problems of needing to disassemble the fixture after disassembly, otherwise it is impossible to lift the disassembled workpiece, needing to add a large number of shims and nuts to meet the assembly of the fixture according to the different heights of the disassembled workpiece, and needing to select different specifications of disassembly fixture plates according to the diameter of the workpiece.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0011] Preferably, each of the mounting brackets is equipped with a roller inside, the bottom of which is located on the upper surface of the planar track, and connecting springs are installed on both sides of the upper surface of the mounting bracket.

[0012] Preferably, one end of the connecting spring is mounted on the lower surface of the connecting plate, and an adjusting bolt is mounted in the middle of the upper surface of the mounting bracket, with one end of the adjusting bolt penetrating through the top of the connecting plate.

[0013] Preferably, an adjusting nut is installed on the outside of the adjusting bolt and above the connecting plate, and a fixing bolt is installed on the bottom side of the connecting plate, with one end of the fixing bolt located inside the support platform.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By rotating the wheel and utilizing the threaded engagement between the double-ended screw and the internal support platform, the distance between the two support platforms can be adjusted to accommodate parts of different sizes.

Detailed Implementation

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 As shown, a gear disassembly tooling frame includes a base 1, columns 2 fixedly installed on both sides of the upper surface of the base 1, a main beam 3 movably installed on the top of the columns 2, a hydraulic cylinder 4 installed on the lower surface of the main beam 3, a planar track 101 installed on both sides of the upper surface of the base 1, a support platform 5 provided on the upper surface of the planar track 101, and elastic support mechanisms 6 provided on both sides of the support platform 5.

[0023] like Figure 1 , Figure 2 As shown, each column 2 has several through holes 201 on its surface. Pins 301 are movably installed on both sides of the main beam 3, with the pins 301 inserted into the through holes 201 at corresponding positions. Support plates 302 are installed on both sides of the lower surface of the main beam 3, with one end of the support plate 302 fitting against one side of the column 2. The support plates 302 guide and position the main beam 3 during installation on the columns 2, simplifying the installation process.

[0024] like Figure 3 As shown, both sides of the two support platforms 5 are rotatably mounted with bidirectional screws 501 via threaded engagement, and one end of each bidirectional screw 501 is equipped with a rotating wheel 502. By rotating the bidirectional screws 501 through the rotating wheel 502, the distance between the two support platforms 5 can be adjusted, facilitating the disassembly of parts of different specifications and broadening the applicability.

[0025] like Figure 1 , Figure 4As shown, the elastic support mechanism 6 includes a mounting frame 601 and a connecting plate 602. The mounting frame 601 is disposed on the upper surface of the planar track 101 and located on both sides of the support platform 5. The connecting plate 602 is installed on both ends of each support platform 5. Each mounting frame 601 is equipped with a roller 603 inside. The bottom of the roller 603 is disposed on the upper surface of the planar track 101. Connecting springs 604 are installed on both sides of the upper surface of the mounting frame 601. One end of the connecting spring 604 is installed on the lower surface of the connecting plate 602. An adjusting bolt 605 is installed in the middle of the upper surface of the mounting frame 601. One end of the adjusting bolt 605 passes through the top of the connecting plate 602. An adjusting nut 606 is installed on the outside of the adjusting bolt 605 and above the connecting plate 602. A fixing bolt 607 is installed on one side of the bottom of the connecting plate 602. One end of the fixing bolt 607 is disposed inside the support platform 5.

[0026] The mounting bracket 601 is connected to the connecting plate 602 by connecting spring 604. By utilizing the elasticity of the spring, the adjusting nut 606 can be rotated in different directions, which can control the suspension and support of the support platform 5, making the disassembly operation simpler.

[0027] The working principle of this gear disassembly fixture:

[0028] The entire platform consists of left and right side columns 2, a height-adjustable main beam 3, support platforms 5, and hydraulic cylinders 4. The left and right side columns 2 and the support platforms 5 are fixed together by a plane track 101 for movement via welding. The hydraulic cylinders 4 are bolted to the main beam 3. The main beam 3 is connected to the two side columns 2 via four pins 301. Two support plates 302 are welded to the main beam 3 for guiding the connection between the main beam 3 and the columns 2. By rotating the rotating wheel 502, the distance between the two support platforms 5 can be adjusted using the threaded engagement between the double-ended screw 501 and the internal thread of the support platform 5, making it suitable for placing parts of different sizes. When lifting and disassembling parts, they are placed on the support platforms 5. By rotating the adjusting nut 606, the position is moved upwards. The elasticity of the connecting spring 604 causes the connecting plate 602 to move the support platform 5 upwards, thus supporting the movement of the support platform. The support platform 5 is suspended in the air. Through the cooperation of the roller 603 and the plane track 101, the front and rear positions of the support platform 5 can be adjusted. After moving to the disassembly position, the adjusting nut 606 is rotated again to lower it so that the bottom of the support platform 5 contacts the plane track 101. Using the support plate 302 as a guide, the main beam 3 is hoisted to a suitable height and connected and fixed to the two side columns 2 with the pin 301 and nut. A pad can be added between the disassembled parts and the hydraulic cylinder 4 to ensure the appropriate stroke of the hydraulic cylinder 4. By rotating the adjusting nut 606, the elasticity of the spring can be used to suspend and support the support platform 5. Parts of different weights can be transported, making the disassembly operation more convenient and improving the disassembly efficiency. By adjusting the installation position of the main beam 3, it can meet the disassembly parts of different sizes, and the detachable main beam 3 makes it easier to hoist the disassembled parts.

[0029] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
