Abstract

This utility model discloses a transmission transition plate installation tool, including a transition plate with guide holes for pre-installation with the transmission. A base is located at the central circular hole of the transition plate. A rocker arm is movably inserted into the bottom of the base. In the initial stage, the tool is in a free state. As the rocker arm rotates clockwise, it pushes four support legs axially forward. The support legs are subjected to axial compression, causing their corresponding flanges to contact the inner circular wall of the transition plate. This indirectly ensures that the transition plate is coaxial with the drive shaft of the test equipment via the tool. Then, the transition plate is fixed to the test equipment with bolts, and the rocker arm is removed, completing the installation of the transition plate. During installation, the cooperation between the base and the four support legs ensures that the transition plate remains concentric with the base, thereby improving the accuracy of the transition plate installation.

Description

Technical Field

[0001] This utility model relates to the field of installation tool technology, specifically a transmission transition plate installation tool. Background Technology

[0002] During the development and testing phase of the manual transmission prototype, a complete testing environment needs to be built in a professional laboratory to fully verify the product's performance. Staff will precisely install the transmission on a custom-designed test bench, and drive the transmission under simulated real-world operating conditions by inputting a motor. This will then involve conducting performance tests covering multiple dimensions, including transmission efficiency, shift response, and torque capacity, as well as durability tests simulating tens of thousands of cycles.

[0003] In this process, the intermediate transition plate plays a crucial role. It is the core connector between the test bench and the gearbox mating surface, and must be compatible with both interface dimensions and assembly requirements. Since the accuracy of test data directly depends on assembly precision, the machining precision requirements for the transition plate are extremely high. Its coaxiality with the test bench input motor must be controlled within 0.03mm, its flatness error must not exceed 0.02mm, and the positional tolerance of the bolt holes must be maintained at the 0.05mm level.

[0004] Such stringent standards pose significant challenges to the manufacturing process, requiring the use of high-precision CNC machining centers in a temperature-controlled workshop environment, and multiple clamping and calibration operations to ensure dimensional stability. During the installation phase, technicians must repeatedly adjust the equipment using precision tools such as dial indicators and laser alignment instruments, often requiring several disassembly and adjustments to achieve acceptable accuracy, significantly increasing the difficulty and time cost of the testing preparation phase.

[0005] Therefore, improvements are needed to address the aforementioned issues. Utility Model Content

[0006] The purpose of this invention is to provide a transmission transition plate installation tool to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a transmission transition plate installation tool, comprising a transition plate, wherein the transition plate is provided with a guide hole for pre-installation with the transmission, and a base is provided at the central circular hole of the transition plate; A rocker arm is movably inserted into the bottom of the base, and four support legs are movably inserted into the outer wall of the base. The other end of each support leg is respectively connected to one side of a flange. The arc-shaped outer wall of the flange is opposite to the inner wall of the central circular hole of the transition plate.

[0008] Preferably, the base has an inner cavity, in which four corner brackets are movably installed, and the rocker arm passes through the bottom of the base and connects to the connecting holes on the four corner brackets.

[0009] Preferably, one end of the support foot extends through the base into the inner cavity, and the end of the support foot located in the inner cavity is integrally provided with an arc-shaped end. One end of the arc-shaped end of each support foot abuts against an arc-shaped outer wall of the four corner pieces.

[0010] Preferably, the other end of the support foot is integrally connected to a plug, and four side strips are integrally connected at equal intervals on the outer wall of the plug.

[0011] Preferably, a recessed insertion hole is provided at the center end of one side of the flange, and four limiting grooves are provided at equal intervals on the inner wall of the insertion hole.

[0012] Preferably, the support foot is inserted into the socket of the flange via a plug, and the four side strips are respectively inserted into the corresponding limiting grooves on the socket.

The front end is positioned using a stop to ensure coaxiality, and then bolted to the drive shaft. Initially, the tool is in a free state. As the rocker arm rotates clockwise, it pushes the four support legs axially forward. The support legs are subjected to axial compression, causing their corresponding flanges to contact the inner wall of the transition plate. This indirectly ensures that the transition plate is coaxial with the test equipment's drive shaft. The transition plate is then bolted to the test equipment, and the rocker arm is removed, completing the transition plate installation. During installation, the cooperation between the base and the four support legs ensures that the transition plate remains concentric with the base, thus improving the accuracy of the installed transition plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 The present invention provides a technical solution: a transmission transition plate installation tool, including a transition plate 1, a guide hole for pre-installation with the transmission on the transition plate 1, and a base 2 at the central circular hole of the transition plate 1; A rocker arm 3 is movably inserted into the bottom of the base 2, and four support legs 4 are movably inserted into the outer wall of the base 2. The other end of each support leg 4 is connected to one side of a flange 5. The arc-shaped outer wall of the flange 5 is set opposite to the inner wall of the central circular hole of the transition plate 1.

[0018] The base 2, support foot 4 and flange 5 are assembled to form the installation tool assembly. In use, the base 2 is connected to the drive shaft of the transmission. The front end is positioned by a stop to ensure coaxiality, and it is installed on the drive shaft of the transmission by bolts.

[0019] The base 2 has an inner cavity 21, in which a four-corner plum blossom piece 22 is movably installed. The rocker arm 3 passes through the bottom of the base 2 and connects with the connecting hole on the four-corner plum blossom piece 22.

[0020] One end of the support leg 4 extends through the base 2 into the inner cavity 21. The support leg 4 is integrally provided with an arc-shaped end 41 at one end of the inner cavity 21. One end of the arc-shaped end 41 of each support leg 4 abuts against an arc-shaped outer wall of the four corner plum blossom parts 22.

[0021] Rotating the rocker arm 3 causes the four corner plum blossom parts 22 to rotate. As the four corner plum blossom parts 22 rotate, their inclined arc-shaped outer walls push the corresponding arc-shaped ends 41 to one side. The movement of the arc-shaped ends 41 then causes the support feet 4 to move to one side, which in turn causes the flanges 5 to move. Finally, one side of each of the four flanges 5 abuts against the inner wall of the transition plate 1, thus maintaining a stable concentric state between the transition plate 1 and the base 2.

[0022] The other end of the support leg 4 is integrally connected to a plug 42, and four side strips 43 are integrally connected at equal intervals on the outer wall of the plug 42.

[0023] A recessed insertion hole 51 is provided at the center end of one side of the flange 5, and four limiting grooves 52 are provided at equal intervals on the inner wall of the insertion hole 51.

[0024] Insert the plug 42 at one end of the support leg 4 into the socket 51 of the flange 5. This will cause the plug 42 to insert the four side strips 43 into the four limiting grooves 52. In this way, the flange 5 will not rotate at the mating end of the support leg 4 during use.

[0025] Working Principle: Before using the gearbox transition plate installation tool, the base 2 is installed on the drive shaft of the bench test equipment. The front end is positioned using a stop to ensure coaxiality, and then bolted onto the drive shaft of the test equipment. Initially, the tooling is in a free state. As the rocker arm 3 rotates clockwise, it pushes the four support legs 4 axially forward. The support legs 4 are subjected to axial compression, causing the corresponding flanges 5 to contact the inner wall of the transition plate 1. This indirectly ensures that the transition plate 1 is coaxial with the drive shaft of the test equipment via the tool. Then, the transition plate 1 is fixed to the test equipment with bolts, and the rocker arm 3 is removed, completing the installation of the transition plate 1. During installation, the cooperation between the base 2 and the four support legs 4 ensures that the transition plate 1 remains concentric with the base 2, thereby improving the accuracy of the transition plate 1 after installation.

[0026] This is the characteristic of the transmission transition plate installation tool. Any content not described in detail in this instruction belongs to the prior art known to those skilled in the art.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
