[0002] The slewing bearing is a new type of mechanical component, also known as a turntable bearing, a rotary bearing or a slewing bearing; it consists of inner and outer rings, rolling elements, etc. It is a large bearing that can withstand comprehensive loads and can withstand large axial, radial loads and overturning moments at the same time.

[0003] In the prior art, in order to ensure the stable operation of the slewing bearing and extend its service life, oiling maintenance after long-term use is particularly important. It can effectively cool the slewing bearing, enhance its pressure resistance, and significantly extend its service life. When performing oiling maintenance, the staff only needs to hold a professional oil gun, accurately place the oil spray head into the oil hole of the slewing bearing, and then gently squeeze the oil gun to evenly inject the lubricating oil into the oil hole to complete the oiling maintenance of the slewing bearing.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0022] The oiling and maintenance device for slewing bearing production provided by the embodiment of the utility model can be applied to the oiling and maintenance work of the slewing bearing, which not only reduces the workload of the staff but also improves the efficiency of the oiling and maintenance of the slewing bearing.

[0023] like Figure 1-Figure 3 As shown, the oiling and maintenance device for slewing bearing production according to the embodiment of the utility model may include a base plate 1 , a bracket 2 , a lifting and fixing mechanism 3 , an oil outlet mechanism 4 and an extrusion assembly 5 .

[0024] As a possible situation, a rubber plate may be installed at the bottom end of the base plate 1 to increase the friction between the base plate 1 and the ground, thereby ensuring the stability of the base plate 1 support.

[0025] The bracket 2 is fixedly connected to the base plate 1 .

[0026] It should be noted that the bracket 2 described in the above embodiment is composed of two groups of vertical plates.

[0027] The lifting and fixing mechanism 3 is installed on the top of the base plate 1;

[0028] It can be understood that the lifting and fixing mechanism 3 can be used to lift and fix the slewing bearing.

[0029] The oil outlet mechanism 4 is installed on the inner side of the bracket 2 and is located above the lifting and fixing mechanism 3 . The oil outlet mechanism 4 may include a support plate 41 , an oil tank 42 , a discharge assembly 43 , a stop plate 44 , a connecting spring 45 and a squeeze plate 46 .

[0030] It should be noted that the oil tank 42 described in the above embodiment is arranged in a circular shape, and the number of the discharge components 43 is the same as the slots of the slewing bearing.

[0031] Among them, the oil tank 42 is fixedly connected to the bracket 2 through the support plate 41, the discharge assembly 43 is installed at the bottom end of the oil tank 42, the inner side of the bracket 2 is fixedly connected with an auxiliary plate, the back plate 44 is fixedly connected with the auxiliary plate through the connecting spring 45, and the inside of the oil tank 42 is slidably connected with an extrusion plate 46, the top end of the extrusion plate 46 passes through the oil tank 42 and the auxiliary plate and is fixedly connected to the bottom end of the back plate 44.

[0032] Specifically, the oil tank 42 is installed under the action of the support plate 41, and the abutment plate 44 and the connecting spring 45 are connected under the action of the auxiliary plate. Then, when the abutment plate 44 is subjected to pressure, the connecting spring 45 contracts, pressing the extrusion plate 46 downward, and after the slewing bearing contacts the discharge assembly 43, the extrusion plate 46 assists in the extrusion of the lubricating oil, thereby achieving the effect of oiling the slewing bearing.

[0033] The extrusion assembly 5 is installed on the top of the bracket 2 , and the extrusion assembly 5 abuts against the abutment plate 44 .

[0034] It can be understood that, under the action of the extrusion assembly 5, the step of extruding the extrusion plate 46 is completed.

[0035] Specifically, in the actual operation process, when the relevant personnel are performing the step of oiling and maintaining the slewing bearing, they place the slewing bearing on the lifting and fixing mechanism 3 and fix it. Under the action of the lifting and fixing mechanism 3, the slewing bearing is fixed and raised until it contacts the discharge assembly 43. Under the action of the discharge assembly 43, the lubricating oil in the oil tank 42 is discharged into the slot of the slewing bearing. At the same time, under the drive of the extrusion assembly 5, the pressure plate 44 and the extrusion plate 46 are pressed to extrude the extrusion plate 46, thereby assisting the discharge of the lubricating oil from the oil tank 42 and completing the step of oiling and maintaining. This not only reduces the workload of the staff, but also improves the efficiency of oiling and maintaining the slewing bearing.

[0036] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the discharging assembly 43 may include a fixing frame 431 , an auxiliary spring 432 , a push rod 433 and an auxiliary rod 434 .

[0039] Specifically, the auxiliary spring 432 and the push rod 433 are installed under the action of the fixing frame 431. When the push rod 433 contacts the slewing bearing, the auxiliary spring 432 and the auxiliary rod 434 are lifted up into the oil tank 42 by the push rod 433 under the pressure of the slewing bearing, thereby causing holes to appear at the bottom of the oil tank 42. The lubricating oil is discharged from the holes to the slots in the slewing bearing, thereby completing the oiling and maintenance work of the slewing bearing.

[0047] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the fixing assembly 34 may include a swing plate 341 , a hinge rod 342 and an arc plate 343 .

[0048] As a possible situation, a limiting plate may be installed at the bottom of the arc plate 343 , and a limiting groove for the limiting plate to slide may be provided on the placement plate 33 , thereby limiting the movement of the arc plate 343 on the placement plate 33 .

[0049] Among them, the swing plate 341 is rotatably installed on the top of the placement plate 33, the swing plate 341 is fixedly connected to the output end of the driving assembly 32, the arc plate 343 is slidably connected to the top of the placement plate 33, and the swing plate 341 is hinged to the arc plate 343 through a hinge rod 342.

[0050] Specifically, driven by the driving assembly 32 , the swing plate 341 swings, and driven by the hinge rod 342 to move the arc plate 343 outward, thereby fixing the inner side of the slewing bearing.

[0054] It should be noted that the outer side of the extrusion wheel 52 is a protruding structure, thereby completing the extrusion of the abutment plate 44 .

[0055] One end of the rotating rod 51 passes through the bracket 2 and is fixedly connected to the driven wheel 53 . The driving wheel 54 is rotatably connected to one side of the bracket 2 . The driving wheel 54 and the driven wheel 53 are connected to each other through a transmission belt 55 .

[0056] Specifically, when the driving wheel 54 rotates, the driven wheel 53 is driven to rotate through the transmission belt 55 , and driven by the driven wheel 53 , the rotating rod 51 and the extrusion wheel 52 rotate, thereby completing the extrusion of the abutment plate 44 .
