The grease head 601 includes bristles 402 for contacting the journal 102 and / or the shoulder 103; the nozzle 603 installed on the extension frame 602 is used to spray grease onto the surface of the journal 102 and / or the surface of the shoulder 103, and the bristles 402 constructed on the grease head 601 are used to contact the journal 102 and / or the shoulder 103, so that the grease on the surface of the journal 102 and / or the surface of the shoulder 103 can be dispersed so as to be evenly coated on the surface of the journal 102 and / or the surface of the shoulder 103.

[0112] The number of nozzles 603 can be determined according to actual needs. In order to facilitate uniform grease coating on the surface of the journal 102 or the shoulder 103, at least two nozzles 603 can be provided on the extension frame 602, and the nozzles 603 are arranged in a row.

Not only can the position of each nozzle 603 be adjusted (the adjustment method can be the same as before), but also the distance between two adjacent nozzles 603 can be adjusted to adapt to different wheel axles 101, which is conducive to improving versatility.

[0113] The grease coating device 600 further includes a grease storage barrel 608 for storing grease, each of the nozzles 603 is connected to the grease storage barrel 608 through a pipeline, and the grease storage barrel 608 can be installed on the Y-axis slide 204.

[0114] It can be understood that one grease storage barrel 608 stores one type of grease. When multiple types of grease are needed, multiple grease storage barrels 608 are needed. For example, two grease storage barrels 608 can be provided to store different types of grease, respectively. Figure 2 shown.

[0115] In this embodiment, the structure of the grease applying head 601 may be the same as the structure of the dust removing head, for example, Figure 4 , Fig.10 and Fig.11 As shown, the grease applying head 601 also includes a brush handle 401, the bristles 402 are fixed to the brush handle 401, the brush handle 401 is detachably mounted on a support frame 403, and the support frame 403 is fixedly connected to the vertical movable frame 303, so as to facilitate the installation and replacement of the brush handle 401, which will not be repeated here.

By constructing the horizontal driving module 604, the extension frame 602 can be driven to perform linear reciprocating motion, thereby driving the nozzle 603 to perform linear reciprocating motion relative to the journal 102 and / or the shoulder 103; combined with the rotation of the axle 101 (wheel pair), the grease sprayed on the surface of the journal 102 and / or the shoulder 103 can be distributed in a spiral shape, and combined with the effect of the bristles 402, the grease can be evenly distributed along the length direction of the journal 102 and / or the shoulder 103, thereby avoiding the accumulation of grease in local areas of the surface of the journal 102 and / or the shoulder 103.

The horizontal driving module 604 includes a fixedly installed horizontal power, which can be a cylinder, an electric cylinder or a hydraulic cylinder, etc. The extension frame 602 is connected to the horizontal power so as to utilize the extension / contraction of the horizontal power to drive the extension frame 602 to perform linear reciprocating motion; and as another example, the horizontal driving module 604 includes a horizontal power, and the horizontal power can be a motor 208. In this case, the horizontal driving module 604 can be a linear module arranged in the horizontal direction; as an example, in this example, Figure 4 , Fig.10 and Fig.11 As shown, the horizontal driving module 604 adopts a GCH4A ball screw 212 module arranged in the horizontal direction, and the slide of the GCH4A ball screw 212 module is connected to the extension frame 602 so as to utilize horizontal power to drive the slide and the extension frame 602 to move linearly synchronously.

[0119] In order to precisely control the position of the nozzle 603, in a more complete solution, it further includes a sensing sheet 304, a fixedly mounted fourth sensor 605, and a fixedly mounted fifth sensor 606, wherein the sensing sheet 304 can be connected to the extension frame 602, and the fourth sensor 605 and the fifth sensor 606 can be fixedly mounted on the horizontal driving module 604, and there is a set distance between the two, such as Figure 4 , Fig.10 and Fig.11 As shown, the fourth sensor 605 and the fifth sensor 606 are respectively used to sense the sensing sheet 304; correspondingly, the fourth sensor 605, the fifth sensor 606 and the horizontal driving module 604 are respectively connected to the controller. During actual operation, the fourth sensor 605 and the fifth sensor 606 respectively play the role of limiting, so that when the extension frame 602 moves to the set position under the drive of the horizontal driving module 604, the sensing sheet 304 just moves to the position of the fourth sensor 605 or the fifth sensor 606. At this time, the fourth sensor 605 or the fifth sensor 606 will generate a sensing signal and send it to the controller. The controller can control the horizontal driving module 604 to stop or move in the opposite direction according to the sensing signal, thereby achieving the purpose of accurately controlling the reciprocating motion of the extension frame 602.

[0120] To improve versatility, in a further embodiment, the grease coating device 600 further includes a sixth sensor 607 which is fixedly mounted. Figure 4 , Fig.10 and Fig.11 As shown, the fifth sensor 606 is located between the fourth sensor 605 and the sixth sensor 607, and the sixth sensor 607 is also connected to the controller. The extension frame 602 can reciprocate between the fourth sensor 605 and the fifth sensor 606 or between the fourth sensor 605 and the sixth sensor 607 under the control of the controller, so that it can adapt to two different types of axles 101 and can grease the journal 102 and / or the shoulder 103 separately.

[0121] In order to better clean and grease the journal 102 and / or shoulder 103 of the wheel axle 101, a constraint mechanism for constraining and driving the wheelset to rotate is usually required at this workstation. For example, the constraint mechanism can adopt a lifting device commonly used in the prior art, and the lifting device is connected to the controller. On the one hand, the lifting device is used to lift the wheel axle 101 to a set height so that the wheel axle 101 can cooperate with this system; on the other hand, the lifting device is used to drive the wheel axle 101 to rotate so as to produce relative movement with the cleaning head, wiping head 505, grease head 601, etc. in this system, so as to better complete the cleaning, oiling, grease and other tasks.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
