Description

Technical Field

[0001] This utility model relates to the technical field of bearing lubrication devices, specifically to a hybrid lubrication device for bearings of a roll grinding machine. Background Technology

[0002] A roll grinding machine is a metal cutting machine tool consisting of a bed, headstock, tailstock, support frame, longitudinal and transverse slides, grinding head, measuring frame, and electrical numerical control system. It comprises five subsystems: a load-bearing system, a drive system, a grinding system, a measuring system, and a control system. The workpiece is supported by the headstock, tailstock, and support frame, and is driven to rotate by the headstock. The numerical control system, based on a mathematical model of the roll surface generatrix, controls the machine tool to perform multi-axis composite motion, achieving grinding of the roll surface metal by the grinding wheel. The online measuring system feeds back measurement data to the grinding machine control system in real time, and the control system performs closed-loop control of the machine tool, thereby completing the precision machining of the workpiece. During roll grinding, when a grinding support structure is used, the bearing pads are used for roll positioning and support. Since the bearing pads are wear parts, their structural design is crucial, directly affecting economic costs, work efficiency, and worker workload. A good lubrication system can also extend the service life of the bearing pads.

[0003] Chinese Patent No. CN221035176U discloses a domestically produced roller grinding machine bearing lubricating oil recovery device, including a central frame. Bearings are provided at the upper and lower ends of the arc-shaped surface of the central frame, and the bottom bearings are offset away from the upper bearings. The arc-shaped surface of the central frame is provided with evenly distributed screw holes at both ends. A connecting groove is provided on the central frame to connect the screw holes on the same side. A connecting groove is provided on the lower side of the arc-shaped surface of the central frame to connect the screw holes on the two bottom sides. An oil outlet pipe is provided on the side of the central frame corresponding to the connecting groove, and the oil outlet pipe is connected to the corresponding screw hole.

[0004] When the roller supports the roll, traditional lubrication devices lubricate the roll by dripping oil, which only provides localized lubrication and cannot adequately lubricate the entire roll and roller, thus affecting the overall lubrication effect. Therefore, it is necessary to propose a hybrid lubrication device for the roller support of a roll grinding machine to solve the problem of poor lubrication in existing technologies when the roller supports the roll. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a mixed lubrication device for roller grinding machine bearings, so as to achieve uniform lubrication of rollers and bearings, improve the overall lubrication effect, and extend service life.

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0022] To solve the above problems, the technical solution adopted by this utility model is as follows: like Figures 1-5 The invention relates to a mixed lubrication device for roller grinding machine bearings, which includes a glycerol lubrication device and an oil-air lubrication device. The oil distribution pipe 8 in the glycerol lubrication device is connected to the oil hole 30 on the bearing, and the grease is delivered through the oil hole 30 to the opening groove 29 on the working surface 27 of the bearing. The oil-air lubrication device includes a lubrication housing and a nozzle 23 connected to the lubrication housing, the nozzle 23 spraying thin oil toward the surface of the roll 31.

[0023] like Figure 4 As shown, the glycerin lubrication device includes a glycerin pump 1, an oil delivery pipe 4, a valve 5, a distributor 6, an oil distribution pipe 8, and a connector 9 connected in sequence. The glycerin pump 1 is connected to a power supply 3 via an electric control switch 2. A distribution valve 7 is provided on the oil distribution pipe 8. The connector 9 is used to connect to an oil hole 30.

[0024] In this embodiment, the distributor 6 is connected to the oil distribution pipe 8 by a threaded connection. Four oil distribution pipes 8 are provided, and each is fixedly connected to a connector 9. The four connectors 9 are respectively connected to the oil holes 30 of the four bearings on the two brackets 24. The oil output is controlled by valves 5 and 7. The electric control switch 2 is connected to the power supply 3 of the grinding machine. The electric control switch 2 is controlled by the grinding machine program and only supplies oil when the headstock rotates, i.e., when the rolls are grinding, thus ensuring lubrication while reducing oil consumption.

[0025] like Figures 1-3 As shown, the bearing is detachably fixed to the bracket 24. Side bearings 25 and lower bearings 26 are respectively provided on the side and bottom of the bracket 24. The side bearings 25 and lower bearings 26 have the same structure, both including a bearing body and an arc-shaped working surface 27 on the bearing body. The bearing body has a countersunk hole 28, and the working surface 27 has an opening groove 29. The oil hole 30 is located on the side of the bearing body and communicates with the opening groove 29. The opening groove 29 is herringbone-shaped, increasing the contact area between the roller 31 shoulder and the lubricating grease.

[0026] like Figure 5 As shown, the oil-air lubrication device also includes a lubricating oil tank 10, which is connected to the lubrication machine housing via an oil pipe. The lubrication machine housing includes a housing and a miniature pneumatic pump 11, a pressure gauge 12, a two-position three-way solenoid valve 13, an exhaust valve 14, a frequency generator 15, a throttle valve 16, an air filter 17, a silencer 18, and a pressure reducing valve 19 disposed within the housing. Multiple sets of miniature pneumatic pumps 11 are provided and connected to the throttle valve 16 respectively. The miniature pneumatic pump 11 is connected to the silencer 18, and the bottom end of the silencer 18 is fixedly connected to the exhaust valve 14. The pressure gauge 12 is connected to the input pipe of the miniature pneumatic pump 11. The oil output is controlled by the two-position three-way solenoid valve 13 and the frequency generator 15. The thin oil, after passing through the concentric pipe 20 to the malleable threaded pipe 22, is atomized under the action of airflow and can evenly adhere to the shoulder of the roll 31, achieving a good lubrication effect.

[0027] The throttle valve 16 is connected to the concentric tube 20, which is a double concentric tube. The concentric tube 20 is connected to a malleable threaded tube 22, which is equipped with a nozzle 23. A magnetic suction cup 21 is fixed at the connection between the concentric tube 20 and the malleable threaded tube 22, and the magnetic suction cup 21 is fixed to the wall. The roller 31 has two shoulders, and the concentric tube 20 has four shoulders. Each shoulder of the roller 31 has a nozzle 23 above and below it to spray thin oil onto the shoulder. As a further optimization, magnetic suction cups 21 are fixed at the four corners of the box, and the box is fixed to the wall by the magnetic suction cups 21.

[0028] The working principle of the oil-air lubrication device is based on conventional technical means. Chinese patents with publication numbers CN 218613481U and CN209309635U disclose a micro-lubrication pneumatic pump device and a micro-lubrication device, respectively. Both disclose the connection method and working principle of the oil-air lubrication device, which will not be described in detail here.

[0029] Specific work process: When the glycerin pump 1 receives the signal of headstock rotation, it starts to work and delivers glycerin (lubricating grease) to the opening grooves 29 of the four bearings through the oil supply pipe 4, valve 5, distributor 6, branch valve 7, oil distribution pipe 8, and connector 9. Under pressure, the glycerin enters the gap between the roll shoulder and the bearing, generating an oil film to play a lubricating role.

[0030] The oil-air lubrication device controls the operation of the micro pneumatic pump 11 through the two-position three-way solenoid valve 13, and the frequency generator 15 controls the amount of oil output. The thin oil reaches the malleable threaded tube 22 through the concentric tube 20 and is atomized under the action of airflow, and is evenly attached to the roll support.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
