Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a four-bar linkage device for lubricating the roller diameter during grinding in a roll grinding machine. Background Technology

[0002] Existing roll grinding machines require a continuous supply of lubricating oil to the roll diameter during grinding. The method of providing continuous lubrication generally involves using an oil spraying device to compress air and thin oil, continuously spraying lubricating oil onto the roll diameter. This method results in high oil consumption, and the oil mist diffuses into the air, polluting the workshop environment. Utility Model Content

[0003] In order to solve the technical problems of high oil consumption and pollution of the workshop environment when providing continuous lubricating oil for the roll diameter in the prior art, this utility model provides a four-bar linkage device for lubricating the roll diameter during the grinding of a roll grinding machine.

[0004] The present invention provides a four-bar linkage device for lubricating the roller diameter during grinding in a roll grinding machine, which adopts the following technical solution: A four-bar linkage for lubricating the diameter of a roll during grinding on a roll grinding machine includes a first bar fixedly mounted on the roll grinding machine; a second bar movably connected to the first bar via a rotating mechanism; a connecting plate fixedly mounted at the end of the second bar, wherein an oil reservoir is provided at the end of the connecting plate away from the second bar; a continuous oil dispensing mechanism fixedly mounted at the bottom of the oil reservoir, wherein the bottom of the continuous oil dispensing mechanism extends outside the oil reservoir and contacts the surface of the roll; and a support mechanism disposed between the rotating mechanism and the connecting plate to fix the moving position of the second bar.

[0005] By adopting the above technical solution: by moving the second rod, the bottom of the continuous oil outlet mechanism is brought into contact with the surface of the roll. Then, the installation position of the second rod is fixed by the support mechanism. During use, the continuous oil outlet mechanism continuously provides lubricating oil to the roll diameter. The oil loss during use is small, and the amount of lubricating oil diffused into the air is also small, which improves the air quality on site and thus effectively improves the production environment in the workshop.

[0006] Furthermore, a handle is fixedly installed on the upper part of the second rod.

[0007] By adopting the above technical solution, the second rod can be moved back and forth by pulling the handle.

[0008] Furthermore, the upper end of the support mechanism is detachably connected to the second rod, and the bottom of the support mechanism is detachably connected to the roll grinding machine.

[0009] By adopting the above technical solution, the support mechanism is fixedly installed on the roll grinding machine, and the installation position of the second rod is fixed by the upper end of the support mechanism.

[0010] Furthermore, the rotating mechanism includes a third rod and a fourth rod arranged in a row, the top of the third rod and the fourth rod being rotatably connected to the side wall of the second rod, and the bottom being rotatably connected to the side wall of the first rod.

[0011] By adopting the above technical solution, the stability of the connection between the second and first rods is increased by simultaneously setting the third and fourth rods, and the impact of machine tool vibration generated during the use of the roll grinding machine on the stable connection between the second and first rods is reduced.

[0012] Furthermore, the continuous oil discharge mechanism includes a support base plate welded to the bottom of the inner side of the oil storage tank; a fixing plate screwed to the upper part of the support base plate; and an oil-absorbing felt detachably installed between the fixing plate and the support base plate. The fixing plate presses down on the upper part of the oil-absorbing felt to fix the installation position of the oil-absorbing felt. The bottom of the oil-absorbing felt passes through the bottom of the oil storage tank and extends downward to contact the surface of the roller.

[0013] By adopting the above technical solution: when in use, lubricating oil is added to the oil storage tank, and the oil-absorbing felt absorbs the lubricating oil into the interior of the oil-absorbing felt. Under its own gravity, the lubricating oil flows out from the bottom of the oil-absorbing felt, continuously providing lubricating oil to the roller diameter for lubrication.

[0014] Furthermore, the support mechanism includes a support rod and a first nut and a second nut screwed onto the upper part of the support rod, and both ends of the support rod are provided with threads.

[0015] By adopting the above technical solution, it is convenient to fix the installation position of the support mechanism, and at the same time, it is convenient to fix the installation position of the second rod.

[0016] Furthermore, the bottom of the support rod is screwed to the upper part of the roll grinding machine.

[0017] By adopting the above technical solution, the installation position of the support rod is fixed.

[0018] Furthermore, an elongated through groove is provided on the upper part of the second rod body, and a second nut and a first nut are screwed to the top of the support rod. The top of the support rod is inserted into the elongated through groove provided on the upper part of the second rod body, the second nut is screwed to the bottom of the elongated through groove, and the first nut is screwed to the upper part of the elongated through groove.

[0019] By adopting the above technical solution, the side wall of the elongated through groove on the second rod is clamped by tightening the second nut upwards and the first nut downwards, thereby fixing the installation position of the second rod.

[0020] In summary, the beneficial effects of this utility model are as follows: This invention, through the setting of a rotating mechanism and a continuous oil delivery mechanism, firstly, the first rod is installed on the upper part of the roll grinding machine. Then, the second nut is locked on the upper part of the support rod, leaving an adjustment distance. The top of the support rod is inserted into the elongated slot in the second rod through the bottom of the elongated slot, and the bottom of the support rod is screwed to the upper part of the roll grinding machine to fix the installation position of the support rod. Next, the distance between the connecting plate and the roll is adjusted by pulling the handle, so that the bottom of the oil-absorbing felt in the continuous oil delivery mechanism can contact the surface of the roll. At this time, the elongated slot at the top of the second rod moves outside the support rod. After the position of the second rod is accurately adjusted, the first nut is locked on the top of the support rod, and the second nut is locked upwards, so that the second nut and the first nut clamp the side wall of the elongated slot on the second rod, thereby fixing the adjusted position of the second rod. Finally, the oil tank is filled with lubricating oil, so that the oil-absorbing felt continuously provides lubricating oil to the roll diameter for lubrication. This invention has a simple structure, low oil loss during use, and less diffusion of lubricating oil into the air, thus improving the air quality on site and effectively improving the production environment in the workshop.

The bottom of the continuous oil dispensing mechanism 7 extends to the outside of the oil storage tank 61 and contacts the surface of the roll. The continuous oil dispensing mechanism 7 continuously provides lubricating oil to the roll diameter for lubrication. A support mechanism 5 is set between the rotating mechanism 2 and the connecting plate 6 to fix the moving position of the second rod 3. The upper end of the support mechanism 5 is detachably connected to the second rod 3, and the bottom is detachably connected to the roll grinding machine. In use, the second rod 3 is moved to bring the bottom of the continuous oil dispensing mechanism 7 into contact with the surface of the roll, and then the moving position of the second rod 3 is fixed by the support mechanism 5.

[0025] Specifically, refer to Figure 2 As shown, the rotating mechanism 2 includes a third rod 21 and a fourth rod 22 arranged in a row. The top of the third rod 21 and the fourth rod 22 are rotatably connected to the side wall of the second rod 3, and the bottom is rotatably connected to the side wall of the first rod 1. By simultaneously setting the third rod 21 and the fourth rod 22, the stability of the connection between the second rod 3 and the first rod 1 is increased, and the impact of machine tool vibration generated during the use of the roll grinding machine on the stable connection between the second rod 3 and the first rod 1 is reduced.

[0026] Moreover, referencing Figure 3 As shown, the continuous oil supply mechanism 7 includes a support base plate 71 welded to the bottom inner side of the oil storage tank 61; a fixing plate 72 screwed to the upper part of the support base plate 71; and an oil-absorbing felt 73 detachably installed between the fixing plate 72 and the support base plate 71. The fixing plate 72 presses down on the upper part of the oil-absorbing felt 73 to fix its installation position. The bottom of the oil-absorbing felt 73 passes through the bottom of the oil storage tank 61 and extends downward to contact the surface of the roll. In use, lubricating oil is added to the inside of the oil storage tank 61. The oil-absorbing felt 73 draws the lubricating oil into its interior, and the lubricating oil flows out from the bottom of the oil-absorbing felt 73 under its own gravity, continuously providing lubricating oil to the roll diameter for lubrication.

[0027] Specifically, refer to Figure 4 and Figure 5As shown, the support mechanism 5 includes a support rod 51 and a first nut 52 and a second nut 53 screwed onto the upper part of the support rod 51. Both ends of the support rod 51 are threaded. The bottom of the support rod 51 is screwed onto the upper part of the roll grinding machine, thereby fixing the installation position of the support rod 51.

[0028] In use, the first rod 1 is first installed on the upper part of the roll grinding machine. Then, the second nut 53 is tightened on the upper part of the support rod 51, leaving an adjustment distance. The top of the second rod 3 is inserted into the elongated slot at the bottom, and the bottom of the support rod 51 is screwed to the upper part of the roll grinding machine to fix the installation position of the support rod 51.

At this time, the elongated slot at the top of the second rod 3 moves outside the support rod 51. After the position of the second rod 3 is accurately adjusted, the first nut 52 is locked on the top of the support rod 51, and the second nut 53 is locked upwards so that the second nut 53 and the first nut 52 clamp the side wall of the elongated slot on the second rod 3, thereby fixing the adjusted position of the second rod 3. Finally, the oil storage tank 61 is filled with lubricating oil so that the oil-absorbing felt 73 continuously provides lubricating oil to the roll diameter. This invention has a simple structure, low oil loss during use, and less diffusion of lubricating oil into the air, thus improving the air quality on site and effectively improving the production environment in the workshop.
