Description

Technical Field

[0001] The present invention relates to the technical field of shaft processing, and specifically to a spraying device for shaft production. Background Art

[0002] A drive shaft is a rotating body with a high rotational speed and few supports. Therefore, its dynamic balance is crucial. Generally, a drive shaft needs to undergo a dynamic balance test before leaving the factory and is adjusted on a balancing machine. For a vehicle with a front-engine rear-wheel drive, it is the shaft that transmits the rotation of the transmission to the main reducer. It can be several sections, and the sections can be connected by universal joints. When installing a conventional segmented drive shaft, first weld the first universal joint fork at one end of the front shaft, press-fit the support and the second universal joint fork at the other end of the front shaft, then synchronously weld the third universal joint fork at one end of the rear shaft and weld the fourth universal joint fork at the other end of the rear shaft, and then connect the second universal joint fork on the front shaft near the support to the third universal joint fork on the rear shaft.

[0003] After the preliminary installation of the first universal joint fork, the front shaft, the support, the second universal joint fork, the third universal joint fork, the rear shaft, and the fourth universal joint fork is completed, a drive shaft assembly is formed. During the production process of the drive shaft, a spraying device is usually used to spray its outer surface to ensure the quality of the drive shaft after production.

[0004] However, most of the current general spraying devices for drive shaft production lack a rotating structure when in use, and it is not convenient to rotate the position of the drive shaft during spraying. Therefore, only one side of the drive shaft can be sprayed, reducing the spraying speed of the drive shaft and thus reducing the spraying efficiency during drive shaft production. To solve the above technical problems, a Chinese patent with the authorization announcement number CN221558828U and the name of a spraying device for drive shaft production is proposed in the prior art. The above patent discloses a spraying device for drive shaft production, including a spraying box. A first motor is fixedly connected to the bottom of the spraying box. The output shaft of the first motor is fixedly connected to a rotating shaft through a coupling. One end of the rotating shaft is fixedly connected to a rotating plate. A rotating frame is fixedly connected to the top of the rotating plate. A placing plate is fixedly connected to the inner bottom wall of the rotating frame. During the spraying process of this spraying device for drive shaft, it can limit the position of the drive shaft and then rotate its position, so as to facilitate spraying different positions of the drive shaft simultaneously. While improving the spraying uniformity of the drive shaft, it also speeds up the spraying speed of the drive shaft and further improves the spraying efficiency of the drive shaft.

[0005] Another example is the Chinese patent with the authorization announcement number CN218308714U, which is named a spraying equipment for wire and cable production. The above patent discloses a spraying equipment for wire and cable production, which relates to the field of cable production technology, including a spraying box, columns are installed at the four corners of the bottom end of the spraying box, a crossbar is installed on one side of the column, a bottom plate is installed on the inner side of the crossbar, and brackets are installed on both sides of the spraying box. The inner side of the bracket is rotatably connected with a first rotating shaft, and the outer side of the first rotating shaft is equipped with a first conveying roller. The top of the bracket is equipped with a stand, and the stand is provided with a slider. The top of the slider is equipped with a spring, and the top of the spring is connected to the inner top of the stand. The inner side of the slider is rotatably connected with a second rotating shaft, and the outer side of the second rotating shaft is equipped with a second conveying roller. A motor is installed on one side of the bracket, and the output end of the motor is connected to one end of the first rotating shaft. The bottom end of the spraying box is provided with an opening. The above patent can effectively feed cables of different diameters, and the liquid collection after spraying is relatively convenient, which has high practical value.

[0006] The existing technologies such as the above-mentioned patents can meet the spraying needs of the rotating shaft to a certain extent, but in the existing technologies such as the above-mentioned patents, the spray tube is in a stationary state during use. Although the rotating shaft can rotate to improve the uniformity of spraying, a large amount of spraying raw materials will be wasted during the spraying process, which has certain shortcomings. Summary of the invention

[0007] The object of the present invention is to provide a spraying device for producing a rotating shaft to solve the problems raised in the above-mentioned background technology.

The transmission rod is drivingly connected to the reciprocating lead screw through an elastic unit, and a second synchronizing member is provided between the adapter rod and the transmission rod.

[0013] Furthermore, the elastic unit includes a sliding rod fixedly connected to the transmission rod. A sliding groove is formed in the reciprocating lead screw.

The positioning portion includes a positioning round rod fixedly connected to the bearing plate. A limiting groove is formed in the base, and the positioning round rod is rotatably and slidably mounted in the limiting groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: In the working process of the spraying device for producing the rotating shaft, during the stroke of the servo motor driving the rotation of the rotating shaft body, the spraying part is driven to reciprocate and slide on the spraying frame through the linkage mechanism to perform spraying operations on the rotating shaft body. At this moment, when the rotating shaft body is installed in a fixed position, the servo motor is used to drive the rotation of the rotating shaft body, so that the surface of the rotating shaft body can be evenly sprayed, which can further improve the uniformity during the spraying of the rotating shaft body. And during the rotation stroke of the rotating shaft body, the spraying part is driven to reciprocate and slide on the spraying frame through the linkage mechanism.

At this moment, compared with the large-caliber spraying amount in the prior art, it can greatly save costs, and the use effect is excellent, which is suitable for wide promotion and use.

The spraying frame 1 is also slidably connected with a moving plate 3, and a clamping space is formed between the moving plate 3 and the positioning plate 2. Specifically, an annular plate is rotatably connected to the moving plate 3 for clamping the rotating shaft body 4.

Specifically, a feed pipe is arranged on the spraying frame, and the feed pipe is connected with the pump body for feeding operation.
