Description

Technical Field

[0001] This utility model belongs to the field of mechanical tooling and relates to a tooling for quickly connecting an engine and an integrated transmission device. Background Technology

[0002] Currently, connecting the engine and integrated transmission system on tank vehicles requires first placing the engine horizontally on a dedicated assembly platform. The platform's adjustment mechanism is then used to ensure that the engine crankshaft center is 1100mm away from the transmission system front to back, and that the engine center is 83mm higher than the transmission center in the vertical direction. Then, the transmission box is used to connect the engine and the integrated transmission system. During this process, due to the large weight of the engine and the integrated transmission system, manual adjustments to the center height and center distance are required, necessitating repeated adjustments and re-measurement of dimensions after each adjustment. This makes it impossible to quickly achieve the required assembly dimensions.

[0003] The connection process between the engine and the integrated transmission requires ensuring that the engine crankshaft center is 1100mm away from the front and rear of the transmission, and that the engine center is 83mm higher than the transmission center in the vertical direction. Due to the large size and weight of the components, it is impossible to adjust to the required dimensions in a short time, which increases the number of back-and-forth fine-tuning times and makes it impossible to quickly complete the assembly of the engine, integrated transmission, and gearbox, thus increasing the unreliability of the assembly.

[0004] Therefore, it is urgent to design a tooling for quickly connecting the engine and the integrated transmission device. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling for quickly connecting an engine and an integrated transmission device. By designing a new connecting tooling, the installation efficiency of the engine and integrated transmission device is improved, saving time and effort. It can not only reduce installation time, but also improve installation accuracy and work efficiency by adjusting the assembly distance in the forward direction through the tooling.

[0006] The technical solution adopted in this utility model is as follows: A tooling for quickly connecting an engine and an integrated transmission device includes an integrated transmission box connector 1, an engine crankshaft center connecting shaft 2, a connecting rod 3, a level 4, and a transmission center connecting shaft 5; One end of the connecting rod 3 is fixed perpendicularly to the central connecting shaft 2 of the engine crankshaft; the connecting rod 3 rigidly connects the central connecting shaft 2 of the engine crankshaft and the integrated transmission box connecting piece 1. The length of connecting rod 3 is 1100mm, and the length of engine crankshaft center connecting shaft 2 is 83mm; A hole is made on the integrated transmission box connector 1 for mounting one end of the transmission center connecting shaft 5; The other end of the transmission center connecting shaft 5 is installed in the positioning hole of the transmission center of the integrated transmission device; The level 4 is installed at the center of the connecting rod 3.

[0007] Furthermore, the engine crankshaft center connecting shaft 2 is designed as a Φ44mm shaft, which is connected to the engine crankshaft center hole.

[0008] Furthermore, a Φ60mm hole is opened on the integrated transmission box connector 1, and it is connected to the center hole of the output end of the integrated transmission device through the transmission center connecting shaft 5.

[0009] Furthermore, the perpendicularity of the connecting rod 3 to the central connecting shaft 2 of the engine crankshaft is 0.1.

[0010] The beneficial effects of this utility model are: Compared to the original structure and its installation and disassembly methods, the improvements in this structure will significantly reduce the costs of installation, disassembly, replacement, and maintenance. Firstly, it reduces the frequency of using large hoisting equipment; secondly, it reduces the frequency of using corresponding measuring tools and minimizes assembly errors. It also lowers the technical skill requirements for maintenance personnel, resulting in a substantial reduction in personnel and equipment investment. Attached Figure Description

Figure 3 This is a schematic diagram of the connecting shaft of the transmission center. Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings.

[0013] Place the engine horizontally on the assembly table, such as Figure 1 As shown.

[0014] Engine leveling: The height difference between the engine parting line and the large reference surface of the assembly table should not exceed 1mm.

[0015] Leveling of the integrated transmission box: Adjust the height of the lower support of the integrated transmission box on the assembly table (the measurement error is not greater than 1mm) so that the dimension H1-H2=51.

[0016] Parallelism adjustment scheme for docking plane: Place the vertical face of a 1m caliper on the transmission box mounting surface, with the extended part of the caliper reaching the end face of the engine flywheel housing. Use a depth gauge to diagonally check that the distance from the vertical face of the caliper to the end face of the engine flywheel housing is no more than 0.5mm.

[0017] To ensure that the engine crankshaft center is 1100mm away from the transmission device front and rear, and that the engine center is 83mm higher than the transmission device center in the height direction, a special tooling was designed.

[0018] The engine crankshaft center hole diameter is 44mm, and the integrated transmission output center hole diameter is 60mm.

[0019] The tooling provided by this utility model for quickly connecting an engine and an integrated transmission device includes an integrated transmission box connector 1, an engine crankshaft center connecting shaft 2, a connecting rod 3, a level 4, and a transmission center connecting shaft 5.

[0020] One end of the connecting rod 3 is fixed to the central connecting shaft 2 of the engine crankshaft, and the perpendicularity of the connecting rod 3 to the central connecting shaft 2 of the engine crankshaft is 0.1.

[0021] The length of connecting rod 3 is 1100mm, and the length of engine crankshaft center connecting shaft 2 is 83mm.

[0022] A hole is made on the integrated transmission box connector 1 for mounting one end of the transmission center connecting shaft 5.

[0023] The other end of the transmission center connecting shaft 5 is installed in the positioning hole of the transmission center of the integrated transmission device.

[0024] The level 4 is installed at the center of the connecting rod 3.

[0025] The engine crankshaft center connecting shaft 2 is designed as a Φ44mm shaft, which can be connected to the engine crankshaft center hole; A Φ60mm hole is provided on the integrated transmission box connector 1, which can be connected to the center hole of the output end of the integrated transmission device through a positioning pin; The connecting rod 3 rigidly connects the engine crankshaft center connecting shaft 2 and the integrated transmission box connecting piece 1. A level 4 is installed on the connecting rod 3. The center lines of the two are 1100mm apart in the horizontal direction and 83mm apart in the vertical direction.

[0026] Insert the engine crankshaft center connecting shaft 2 into the hole in the center of the engine crankshaft. Adjust it with a level 4 so that the connecting rod 3 is in a horizontal state. Connect the hole on the integrated transmission box connector 1 and the center hole of the output end of the integrated transmission device through the positioning pin. This ensures that the engine crankshaft center is 1100mm away from the transmission device in the front and rear directions, and the engine center is 83mm higher than the transmission center in the height direction.
