Description

Technical Field

[0001] The present application relates to the technical field of press-fitting of vehicle wheelset bearings, and in particular to a grease coating system. Background Art

[0002] Before the bearing is pressed on the wheelset, the journal needs to be smeared with grease or other lubricants to ensure smooth press-fitting and reduce damage to the axle and bearing. At present, the journal is mainly greased manually, that is, workers use a brush to dip the lubricant in the lubricant barrel and then apply it to the journal. Due to the heavy weight of the wheelset, the wheelset is placed on the track, and workers need to squat on the ground to operate. In order to ensure that the lower part of the journal is evenly coated, they can only operate half-lying on the ground or repeatedly stand up to push the wheelset. The operating space in this scenario is very small, and the workstation is often located near the press machine. There are certain safety hazards for workers. Moreover, a worker can only brush one end of the journal at a time, which is very inefficient and cannot rotate the wheelset while grease is applied. The manual operation process cannot guarantee the effect of lubricant application, which is prone to uneven application, missing application, over-application, etc., which in turn affects the quality of press-fitting. Moreover, the barrels containing lubricants are usually opened and placed on the ground, which can easily cause dust and impurities in the workshop to fall into and contaminate the lubricants. If the lubricants are unfortunately hard particles, they can easily scratch the journals and cause heavy losses. Summary of the invention

[0042] Referring to FIGS. 1 to 3 , the present application provides a grease coating system, which includes a wheel device 1000 and a grease coating device 2000. The wheel device 1000 is used to rotate a target wheel body 100, which can be determined as a wheel body of various types or models according to requirements, including but not limited to a vehicle wheel pair as shown in FIG. Among them, the wheel device 1000 can construct a wheel body accommodating space or a wheel body accommodating area for placing the target wheel body 100, so that the target wheel body 100 can be placed in the wheel device 1000 according to a preset angle, method, etc. After the target wheel body 100 is placed in the wheel device 1000, the target wheel body 100 can be driven based on the drive of the wheel device 1000, so that the target wheel body 100 rotates in a fixed axis according to a preset method, wherein the rotation of the target wheel body 100 causes the journal 100a on the target wheel body 100 to also rotate in a fixed axis synchronously.

[0043] The wheel device 1000 can be formed by different transmission or driving modes according to the needs, and can be set to a variety of different structures according to the needs. For example, in one of the embodiments, the wheel device 1000 may include a main frame 1100 and a wheel assembly 1200. The main frame 1100 is the basis of the entire wheel device 1000, and the wheel assembly 1200 can be arranged on the main frame 1100, wherein the wheel assembly 1200 is used to rotate with the target wheel body 100, so that the wheel body accommodating space or wheel body accommodating area for placing the target wheel body 100 can be constructed in the wheel device 1000 by the wheel assembly 1200, so that the target wheel body 100 can be placed on the wheel assembly 1200 according to a preset angle, mode, etc., and at this time, the wheel assembly 1200 can be used to drive the target wheel body 100 to rotate relative to the main frame 1100, thereby driving the journal 100a to rotate synchronously. In addition, the rotating wheel device 1000 may also use other base bodies, brackets and other structures as the basis of the entire device for assembling other components of the rotating wheel device 1000, which is not limited here.

[0044] Continuing to refer to FIG. 1 , in one embodiment, the wheel device 1000 may further include other functional components such as a lifting component 1300 and a centering component 1400 for use with the wheel assembly 1200. The lifting component 1300 may be disposed on the main frame 1100, and the wheel assembly 1200 may be disposed on the lifting component 1300, and thus the lifting component 1300 may be assembled on the main frame 1100, and therefore, the lifting component 1300 may control the lifting and lowering of the wheel assembly 1200 relative to the main frame 1100, and further control the lifting and lowering of the target wheel body 100 placed on the wheel assembly 1200. In one embodiment, the lifting assembly 1300 may include a lifting drive 1300a, a screw transmission component 1300b and two lifting bodies 1300c. For example, the two lifting bodies 1300c are symmetrically arranged on symmetrical sides of the main frame 1100, and the lifting drive 1300a is located inside the main frame 1100. The lifting drive 1300a is connected to the two lifting bodies 1300c through the screw transmission component 1300b. When the lifting drive 1300a is started, it can be used to drive the two lifting bodies 1300c to rise and fall synchronously, thereby controlling the overall smooth lifting and lowering of the rotating wheel assembly 1200.

[0045] The centering assembly 1400 may be disposed on the main frame 1100, and the centering assembly 1400 may be used to drive the contact with the target wheel body 100, thereby controlling the axial direction of the target wheel body 100 to be parallel to the axial direction of the coating roller 2200 of the grease coating device 2000, so that the target wheel body 100 can be placed in a suitable placement state after being placed on the rotating wheel assembly 1200, so that the journal 100a of the target wheel body 100 can be accurately matched with the grease coating device 2000 in position and angle. For example, the centering assembly 1400 may include a hydraulic cylinder and a centering plate, and the hydraulic cylinder drives the centering plate to drive the contact with the target wheel body 100, so that the target wheel body 100 stops at a preset fixed position, forming a central symmetric control with the grease coating device 2000.

[0046] In one embodiment, the wheel assembly 1200 may include a rotation driver 1200a and a plurality of driving wheels 1200b, at least one pair of driving wheels 1200b is provided on each lifting body 1300c, the rotation driver 1200a is used to drive at least one pair of driving wheels 1200b to rotate, the driving wheels 1200b are used to rotate in contact with the target wheel body 100, and drive the target wheel body 100 to rotate relative to the main frame 1100. For example, a pair of driving wheels 1200b is provided on each lifting body 1300c, and two lifting bodies 1300c located on both sides of the main frame 1100 are provided with two pairs of driving wheels 1200b in a symmetrical relationship. At this time, the two wheels of the target wheel body 100 can be placed on the two pairs of driving wheels 1200b in a symmetrical relationship respectively, and the driving wheels 1200b can be rotated in contact with the target wheel body 100 when started, and drive the target wheel body 100 to rotate relative to the main frame 1100.

[0047] Continuing to refer to FIG. 3 , the grease coating device 2000 may include a storage body 2100 and a coating roller 2200. The storage body 2100 has a storage cavity inside. The top of the storage body 2100 is provided with a cavity outlet 2100a connected to the storage cavity. The storage cavity is used to store lubricating substances, such as grease. The number of coating rollers 2200 is set to an even number and matched in pairs. At least one pair of coating rollers 2200 is rotatably assembled on the top of the storage body 2100, and a rolling accommodation space 2200a is formed between each pair of coating rollers 2200. The rolling accommodation space 2200a is used to accommodate the journal 100a of the target wheel body 100.

[0048] For example, a pair of coating rollers are arranged on the storage body 2100. When the surface of the journal 100a is placed in the rolling accommodation space 2200a between the pair of coating rollers, the wheel surface of the coating roller 2200 can be used to roll with the surface of the journal 100a of the target wheel body 100. At this time, at least a portion of the wheel surface of at least one coating roller 2200 is located inside the storage cavity, so that the coating roller can continuously use the portion of its wheel surface located in the storage cavity to contact and carry the lubricating substance during the rotation process, and then apply the lubricating substance to the surface of the journal 100a of the target wheel body 100 when the wheel surface of the coating roller rolls with the surface of the journal 100a of the target wheel body 100.

[0049] The surface of the coating roller 2200 can also be coated with elastic material, so that the elastic material and the journal 100a can be deformed in contact without damaging the surface of the journal 100a. At the same time, the end surface of the coating roller 2200 can have sufficient elastic capacity to ensure that the lubricant is fully applied without damaging the surface of the wheel axle.

[0050] In one embodiment, a plurality of cavity outlets 2100a are provided on the top of the storage body 2100, all of which are connected to the storage cavity, and each coating roller 2200 is located in a corresponding cavity outlet 2100a, wherein a portion of the wheel surface of each coating roller 2200 passes through the corresponding cavity outlet 2100a and is located inside the storage cavity, for contacting the lubricating substance stored in the storage cavity and coating the surface of the journal 100a of the target wheel body 100. For example, as shown in FIG3 , two pairs of cavity outlets 2100a are provided on the top of the storage body 2100, and a coating roller is rotatably mounted on each cavity outlet 2100a, wherein the coating roller can be assembled on the cavity outlet 2100a by overlapping the rotating shaft assembled on the storage body 2100, and by adjusting the height of the coating roller and the rotating shaft on the cavity outlet 2100a, a portion of the wheel surface of the coating roller is placed in the storage cavity, for contacting and carrying the lubricating substance. The axial length of the coating roller 2200 may be limited to be greater than the axial length of the journal 100 a of the target wheel body 100 .

[0051] Continuing to refer to FIG. 3 , the grease coating device 2000 includes a scraper assembly, which is disposed on the top of the storage body 2100. The scraper assembly includes a scraper plate 2300a, and the number of the scraper plates 2300a is set to be multiple. At least one scraper plate 2300a is correspondingly disposed at each cavity outlet 2100a. A scraper gap is set between the scraper plate 2300a and the wheel surface of the coating roller 2200. The scraper gap is used to adjust the thickness of the lubricating substance contacted by the wheel surface of the coating roller 2200. Therefore, as the coating roller rotates, the scraper plate 2300a can scrape off the lubricating substance contacted and carried by the coating roller based on the preset scraper gap, so that the coating roller can only carry the lubricating substance of the preset thickness.

[0052] In one embodiment, each cavity outlet 2100a is provided with at least one pair of scraper plates 2300a, and each pair of scraper plates 2300a is symmetrically arranged on both sides of the corresponding coating roller 2200 along the axis of the coating roller 2200, and scraper gaps of the same size are formed on both sides of the coating roller 2200. The two symmetrical scraper gaps on both sides of each coating roller 2200 are used to jointly adjust the thickness of the lubricating substance in contact with the wheel surface of the coating roller 2200.

[0053] Continuing to refer to FIG. 3 , the grease coating device 2000 may further include a detection sensor 2400, which is disposed in the rolling accommodation space 2200a formed between the paired coating rollers 2200, and the detection sensor 2400 is used to detect the placement state of the journal 100a of the target wheel body 100 in the rolling accommodation space 2200a. The detection sensor 2400 may be a distance sensor capable of measuring distance, so the detection sensor 2400 may be used to measure the distance between the journal 100a and the detection sensor 2400. When the journal 100a of the target wheel body 100 is placed in the rolling accommodation space 2200a, the detection sensor 2400 may obtain the distance data of the journal 100a, and determine whether the journal 100a is installed in place based on the distance data.

[0054] In one embodiment, the greasing device 2000 includes a device base 2500 and a moving component 2600, the moving component 2600 is disposed on the device base 2500, the storage body 2100 is disposed on the moving component 2600, the moving trajectory of the moving component 2600 is parallel to the axial direction of the coating roller 2200, and the moving component 2600 is used to move the storage body 2100 relative to the device base 2500 along the moving trajectory.

[0055] Therefore, after the target wheel body 100 is centered and stopped, the lifting assembly 1300 of the rotating wheel device 1000 can lift the target wheel body 100, and the moving assembly 2600 of the grease coating device 2000 can push the storage body 2100 to move inward to the bottom of the shaft neck 100a, and the lifting assembly 1300 then descends with the target wheel body 100 until the shaft neck 100a of the target wheel body 100 enters the rolling accommodating space 2200a, and makes the shaft neck 100a and the coating roller of the grease coating device 2000 present surface-to-surface rolling contact. At this time, the detection sensor 2400 can be used to determine whether it is in place. For example, the lifting assembly 1300 stops descending until the detection sensor 2400 is triggered. At this time, the wheel assembly 1200 of the wheel device 1000 controls the rotation of the target wheel body 100, and at the same time drives the shaft neck 100a to rotate synchronously. The shaft neck 100a is in rolling contact with the coating roller, so that the coating roller rotates synchronously, and the lubricating substance is evenly applied to the shaft neck 100a through contact and carrying the lubricating substance through rolling contact.

[0056] In one embodiment, the greasing system may further include a visual device 3000, which is arranged directly above the greasing device 2000 and is used to obtain the greasing state image of the journal 100a of the target wheel body 100 on the greasing device 2000. The visual device 3000 can cooperate with the rotating wheel device 1000 to take photos multiple times in the radial direction, and automatically determine whether the lubricating material completely covers the surface of the journal 100a by identifying the greasing state image. The recognition standard is the ratio of the greasing area to the total area. After identification, if the ratio is greater than the value set by the system, it is judged to be qualified. If the ratio is less than the system setting value, it is judged to be unqualified. When the judgment result is unqualified, the system records the judgment result and automatically cycles to grease again. If the greasing is still judged to be unqualified after 2 times, an alarm prompt is issued, and the reason for the unqualified is manually checked, and the unqualified area is manually supplemented. The system value of the ratio can be modified according to different usage needs. The journal 100a is the metallic color of stainless steel, and the lubricating substance may be white, yellow, dark blue, etc. according to different types, so that the color contrast between the lubricating substance and the journal 100a is obvious, which is convenient for image recognition.

[0057] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
