Description

Technical Field

[0001] This invention relates to the field of gearbox shaft assembly technology, and more specifically to an automatic gear-aligning device for a multi-gear gearbox shaft system. Background Technology

[0002] The shaft system is one of the important components of a manual transmission (also known as a manual gearbox), and its assembly quality directly affects the overall performance of the manual transmission. For example... Figure 1 , 2 The diagram shows the structure of a common manual transmission, which includes a housing 1 and a primary shaft 4, a secondary shaft 5, an intermediate shaft 3, and an idler shaft 6 assembled inside the housing 1. During the assembly of the shaft system into the transmission, the gears of the primary shaft, secondary shaft, intermediate shaft, and idler shaft need to be meshed simultaneously.

[0003] The existing technology involves manual assembly. This involves manually installing the two-axis gear system and then the one-axis gear system sequentially. A press then presses in the left and right fixed bearings to the housing, followed by the intermediate shaft gear system. A locating sleeve secures the left end of the intermediate shaft, and the press then presses in the bearing from the right end. After the locating sleeve is removed manually, the press then presses in the bearing from the left end of the intermediate shaft. Because the two-axis gear system has a large shaft diameter, the operating space within the housing is limited, making manual assembly of the intermediate shaft gear system difficult. Furthermore, this method cannot achieve dynamic press-fitting of the left and right bearings of the intermediate shaft, and the intermediate shaft is in a cantilevered state during press-fitting, resulting in a high jamming rate. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic gear alignment device for a multi-gear transmission shaft system, which solves the problem of high operational difficulty in manual assembly, overcomes the jamming fault caused by the intermediate shaft being in a cantilever state during the press-fitting process, and ensures the assembly quality of the transmission shaft system.

Detailed Implementation

[0039] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0040] As mentioned above, combined with Figure 3 , 4 As shown, the present invention provides an automatic gear-aligning device for a multi-gear transmission shaft system, including a support frame 100, a support assembly 200, two lifting cylinders 210 and a gear-aligning rotation mechanism 300.

[0041] The support assembly 200 is disposed beside the support frame 100 and is used to support the tray 2, on which the housing 1 is supported; two lifting cylinders 210 are disposed at intervals on the support assembly 200, and the telescopic rods of the two lifting cylinders 210 are both arranged vertically, and each telescopic rod is provided with a support member for lifting the intermediate shaft 3 to be aligned from both ends of the housing 1; the gear alignment rotation mechanism 300 is disposed on the support frame 100 and is used to drive the intermediate shaft 3 to rotate forward or backward to realize the gear alignment of the shaft system.

[0042] In the technical solution provided by the present invention, the intermediate shaft 3 to be aligned is supported by the two ends of the housing 1 through the support members on the telescopic rods of the two lifting cylinders 210. This can achieve the pre-centering of the intermediate shaft 3.

[0043] Then, the tooth-aligning rotation mechanism 300 set on the support frame 100 is used to drive the intermediate shaft 3 to rotate forward or backward, so as to imitate the manual forward and reverse rotation of the intermediate shaft 3 to achieve the purpose of tooth alignment.

[0044] The automatic gear-aligning device provided by this invention greatly increases the success rate of shaft gear alignment. Compared with the existing manual gear-aligning methods, it significantly reduces the difficulty of operation and has good application prospects.

[0045] According to the automatic tooth-aligning device provided by the present invention, the support member functions in conjunction with the telescopic rod of the lifting cylinder 210 to limit and support the intermediate shaft 3 to be aligned. The support member can specifically be exemplified by a robot gripper as known to those skilled in the art. In some embodiments, the support member is preferably a U-shaped block 211, which has a U-shaped groove for limiting and supporting the intermediate shaft 3 to be aligned; by using the U-shaped block 211 as the support member, it has the advantages of simple structure and low cost.

[0046] In this invention, the tooth-aligning rotation mechanism 300 functions to mimic the manual forward and reverse rotation of the intermediate shaft 3 to be aligned, thereby achieving tooth alignment between the intermediate shaft 3 and the primary shaft, the secondary shaft, and the idler gear shaft. Combined with... Figure 5 , 6 As shown, in some embodiments, the gear-rotating mechanism 300 includes a base plate 310, a floating seat 320, a guide elastic component, a drive source, and a drive gear 330;

The transition gear 370 meshes with the rack 341. In actual operation, the telescopic rod of the cylinder 340 drives the rack 341 to reciprocate in the vertical direction, thereby driving the transition gear 370 meshing with it to rotate in the forward or reverse direction, further driving the drive gear 330 with a coaxial core to rotate in the forward or reverse direction to achieve the effect of actuating the intermediate shaft 3. During the forward or reverse rotation of the intermediate shaft 3, it simultaneously meshes with the first shaft, the second shaft, and the idler shaft.
