TECHNICAL FIELD
[0001] The utility model relates to the technical field of axle pin, concretely is a quick connection transmission axle pin structure. BACKGROUND
[0002] In the automobile manufacturing and maintenance industry, the transmission axle pin plays a key role, it is the important part that guarantees the stable transmission of power from the engine to the wheel, and its performance and reliability are directly related to the overall operation of the automobile. The automobile transmission axle pin widely used in the market at present mainly consists of three parts: axle pin body, gasket and cotter pin.
[0003] On the automobile production line, installing the transmission axle pin is a relatively tedious process. Workers need to first accurately insert the axle pin body into the corresponding installation hole, then place the gasket, and finally install the cotter pin. This series of operations not only requires workers to have high operational proficiency, but also takes a lot of time. According to relevant statistics, it takes about five to eight minutes to install an average transmission axle pin in the conventional automobile production process, which greatly affects production efficiency for the automobile manufacturing industry that pursues high efficiency. If the installation worker makes a slight deviation, for example, the cotter pin is not correctly bent and fixed, it will cause the transmission axle pin to loosen during vehicle operation, and further cause abnormal vibration and noise of the transmission shaft, and in severe cases, it may even cause power transmission interruption, endangering driving safety.
[0004] From the perspective of storage management, this transmission axle pin composed of multiple independent components also has great disadvantages. In the warehousing link of automobile parts, the axle pin body, gasket and cotter pin are usually stored separately. Due to the small size and light weight of the cotter pin, it is easy to be lost during frequent cargo handling and inventory operations. This not only causes waste of parts and increases the procurement cost of enterprises, but also in the automobile maintenance scene, if the transmission axle pin is urgently needed but the parts are found to be missing, it will seriously delay the maintenance progress, bring great inconvenience to the car owner, and also damage the service image of the maintenance enterprise.
[0005] In summary, the existing automobile transmission axle pin structure has obvious shortcomings in installation convenience and storage stability, and has been difficult to meet the needs of the rapid development of the current automobile industry. Developing a new type of transmission axle pin with more optimized structure, more convenient installation and more reliable storage has become an important issue to be solved in the field of automobile manufacturing and maintenance.
[0006] Therefore, we propose a quick connection transmission axle pin structure to solve the above problems. UTILITY MODEL CONTENTS

[0037] Among them:
[0038] Adjusting block 7 is slidably fitted on guide rail 5.
[0039] Sliding column 9 is slidably fitted in arc-shaped groove 8.
[0040] The first guide 6 is used for the stable movement of adjusting column body 13, and the second guide 12 is used for the stable movement of split pin bar 11.
[0041] Adjusting column body 13 is used in cooperation with threaded rotating part 14.
[0042] Working principle:
[0043] Initial state: the split pin bar 11 is located in the shaft pin 1, and the sliding column 9 is located at the left end of the arc-shaped groove 8.
[0044] In use, first, the gasket 2 is sleeved on the shaft pin 1, then the shaft pin 1 is inserted into the required connection position, and then the threaded fastener 14 is rotated by external force, at this time, the adjusting column 13 will move laterally under the rotation of the threaded fastener 14 on the shaft pin 1 through its own threaded hole, that is, at this time, the adjusting column 13 will move laterally with the adjusting block 7 under the assistance of the first guide 6;
[0045] Further, under the movement of the adjusting block 7, the sliding column 9 in the arc-shaped groove 8 will move in position during the process, and in the movement, the sliding column 9 will move the split pin bar 11 out of the shaft pin 1 with the connecting block 10 under the assistance of the second guide 12, and thus complete the connection action with the required connection part;
[0046] Further, through one-key clamping connection of the whole device, the convenience is high: after the shaft pin 1 body is inserted into the mounting hole, through a simple operation of rotating the threaded fastener 14, the split pin bar 11 on the shaft pin 1 body will be clamped with the clamping groove on the inner wall of the mounting hole of the required installation position instantaneously; complete the close connection; compared with the installation of the traditional transmission shaft pin 1, the whole installation process can be shortened; on the automobile production line, this means that more vehicles can be assembled per unit of time, improving production efficiency and reducing production cost; for automobile repair shops, vehicle repair can also be completed faster, reducing customer waiting time;
[0047] Reduce installation difficulty and enhance installation stability: the simple and intuitive operation mode reduces the requirement for the skill level of the installer; even workers with relatively less experience can perform installation operations skillfully after simple training, reducing installation quality problems caused by improper human operation and improving the installation qualification rate of the product;
[0048] Convenient for quality detection: in the later use, only by observing the state of the alignment mark on the threaded fastener 14 during installation, whether the transmission shaft pin 1 is installed correctly can be quickly judged, improving the efficiency and accuracy of quality detection, which helps to find and solve problems in the installation process in time and ensure product quality.
[0049] Further, by integrating the shaft pin 1 with the cotter bar 11, unlike the traditional design of separating the shaft pin 1 from the cotter bar 11, which brings many inconveniences to the installation and storage links; now the integration improvement can improve the storage benefits and avoid the loss of parts: the separated cotter bar 11 is easy to lose in the links of storage, transportation, etc. After the integration design, there is no separate cotter bar 11 component, which fundamentally solves the loss problem caused by the scattered parts; this makes the automobile parts supplier not worry about the inventory loss caused by the loss of the cotter bar 11 in warehouse management, and the automobile production enterprises and repair factories will not be affected by the normal production and repair work due to the lack of cotter bar 11, reducing the additional procurement and waiting costs.
[0050] Convenient classification management: in the parts warehouse, the traditional shaft pin 1 and the cotter bar 11 need to be stored and managed respectively, and it is easy to cause confusion and misplacement; the integrated transmission shaft pin 1 as an independent and complete component is more convenient for classification storage and identification, and it is also more clear and explicit when checking inventory, improving the efficiency and accuracy of warehouse management.
