Description

Technical Field

[0001] The utility model relates to the technical field of automobile axle part assembly, in particular to a glue coating device for the mounting surface of an axle half shaft. Background Art

[0002] The axle half shaft is one of the important components on an automobile drive axle, bearing the important function of driving the wheels. When assembling the axle half shaft and the wheel hub, it is necessary to apply a sealing glue on the mounting surface of the half shaft to prevent the lubricating oil inside the axle from leaking, and the leakage of the lubricating oil will cause pollution and damage to the axle without lubrication. Currently, the conventional glue coating for the axle half shaft is manually pressing a glass glue gun to apply the sealing glue on the mounting surface of the half shaft. When performing the glue coating operation, it is necessary for an operator to rotate the half shaft with one hand and hold the glass glue gun with the other hand to align it with the mounting surface of the half shaft and press the glue gun to apply the glue. However, this manual glue coating method has many problems. Firstly, there is randomness in manual application of the sealing glue, with poor consistency. The width of the glue strip is uncontrollable, and the sealing track of the glue strip is uncontrollable. It is also easy to cause missed coating and discontinuous and incoherent glue strip tracks. Secondly, the force applied by the operator to press the glass glue gun varies, resulting in different glue output amounts. Excessive force leads to excessive glue output and waste, while insufficient force leads to insufficient glue output and poor sealing effect. Moreover, the operation of manually applying glue to the mounting surface of the half shaft is inconvenient, the operation process is relatively cumbersome, the labor intensity is high, and the efficiency is low, resulting in a relatively high labor cost, thus leading to a relatively high product manufacturing cost.

[0046] The glue application method using the above glue application device for the axle half shaft mounting surface includes the following steps:

[0047] A. Grasp the axle half shaft 80, place it vertically between the half axle positioning and rotating assembly 20 and the half axle pressing component 30, place its bottom on the rotating positioning disk 24, insert the positioning pins 27 and 28 into the center hole of the bottom end face of the axle half shaft and one of the bolt holes of the flange face for positioning respectively.

[0048] B.

[0049] C. After the glue application is completed, the glue supply assembly 60 stops conveying the sealant. The glue applicator head moving assembly 40 drives the glue applicator head assembly 50 to move out above the half axle positioning and rotating assembly 20. The driving motor 22 pauses, the rotating positioning disk 24 stops rotating, and the piston rod of the first cylinder 31 retracts. Under the action of the return spring, the first slider drives the downward pressing moving plate 34 to move upward, and then the axle half shaft 80 can be taken out.

[0050] The utility model adopts a mechanical device to apply glue to the mounting surface of the axle half-axle, and the gluing speed is fast and the efficiency is high. The width of the glue strip is stable and uniform, the consistency of the finished glue product is good, and the sealing trajectory of the glue strip is controllable, thus avoiding the problems of missing coating and discontinuous glue strip trajectory. The gluing position is controlled by a gluing head moving component, and the glue output is controlled by a quantitative valve, thus reducing the waste of sealant and leakage caused by poor sealing. At the same time, no personnel participation is required in the gluing process, which greatly reduces the labor intensity and the employment cost, thus not only improving the production efficiency but also reducing the production cost of the enterprise.

[0051] The lateral moving module, longitudinal moving module and lifting moving module of the glue head moving assembly can drive the glue head assembly to move in multiple directions and accurately position. The universal bull's eye roller is used to contact the top end face of the axle half shaft, which will not cause half shaft wear.

[0052] When the coating needle is not in use, it can be immersed in the anti-solidification solution of the measuring cup to prevent the sealant from solidifying and clogging the coating needle, so that the axle half-shaft mounting surface can be quickly coated with glue when it is used again.

[0053] In actual application, multiple workstations can be set on the frame to carry out glue coating in turn to improve production efficiency. It should be noted that the control method and software method of the PLC controller for each component are common methods in the prior art, and the utility model does not involve any improvement in the control method and software.
