The first positioning pin outer sleeve is connected to a stop ring located between the front pivot casing and the casing body; the bearing seat outer sleeve is connected to the casing body through a second threaded connector. The utility model has a simple connection method, which is convenient for disassembly and assembly. The casing body of this structure not only meets the support function, but also has sufficient strength, rigidity, reliability, stability, etc.
[0004] Although the above device has sufficient strength, there are still some problems when using the device:
[0005] 1. The device does not have a shock absorbing mechanism. When the device is used, the rotation of the internal main shaft, bearings and other components will cause the device to vibrate strongly, making the connecting parts easy to loosen and the structure prone to fatigue, reducing the service life of the device.
[0006] 2. The device does not have an automatic timed lubrication mechanism, and the bearings often need to be lubricated and maintained during use, resulting in a waste of manpower and time.
[0007] In view of the above situation, technical innovation is carried out on the basis of the existing bearing casing. Utility Model Content
[0008] The purpose of the utility model is to provide a bearing casing structure to solve the problems raised in the above background technology.
[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bearing casing structure, comprising a mounting seat and a casing body, a shock absorbing platform is fixed to the bottom end of the mounting seat, and a shock absorbing rubber block is fixed to the middle part of the bottom end of the shock absorbing platform, a fixing seat is fixed to the bottom end of the shock absorbing rubber block, and shock absorber cylinders are fixed to the left and right ends of the fixing seat, a sealing ring is fixed to the top end of the shock absorber cylinder, and a shock absorbing spring is fixed to the inner bottom wall of the shock absorber cylinder, a piston is fixed to the top end of the shock absorbing spring, and an oil hole is opened on the inner side of the piston, a throttle valve is fixed to the bottom end of the oil hole, an inner rod is fixed to the top end of the piston, and the inner rod coincides with the center axis of the piston, and the casing body is fixed to the top end of the mounting seat.

[0012] Furthermore, a one-way air inlet valve is fixed on one side of the top of the lubricating oil tank, and a micro oil pump is fixed on one outer wall of the lubricating oil tank, and an oil delivery pipe is fixed on the output end of the micro oil pump.
[0013] Furthermore, an oil filling assembly is fixed to the side of the top of the lubricating oil tank away from the one-way air inlet valve, and the oil filling assembly includes an oil filling port and a high-pressure oil filling valve, and a high-pressure oil filling valve is fixed to the bottom end of the oil filling port.
[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the device is provided with a shock absorbing mechanism, which can reduce the shock of the device, thereby avoiding strong vibration of the device when the bearing rotates, thereby reducing the damage to the components caused by the vibration and increasing the service life of the device; at the same time, the device is provided with a lubrication mechanism, which can release lubricating oil to lubricate the bearing at a regular time, thereby reducing the number of maintenance times by personnel and helping to save manpower.
[0015] 1. The utility model is provided with a mounting seat, a shock absorbing platform, a shock absorbing rubber block, a fixing seat, a shock absorber cylinder, a sealing ring, a shock absorbing spring, a piston, an oil through hole, a throttle valve, an inner rod and a casing body. When the casing body vibrates, the shock absorbing spring can be compressed and absorb the impact force generated by the vibration of the casing body.

When the shock absorbing spring and the inner rod are contracted, the piston is pressed downward, and the hydraulic oil in the lower oil chamber will flow into the upper oil chamber through the oil through hole. Since the throttle valve can limit the flow rate of the hydraulic oil, the extension and contraction speed of the inner rod will be reduced, forming a certain telescopic damping, avoiding the shock absorbing spring from being compressed too quickly or rebounding too quickly, reducing the rebound impact force of the shock absorbing spring, and improving the shock absorbing effect. The shock absorbing rubber block can further improve the shock absorbing effect of the device and enhance its shock filtering performance. Through the above structure, the device can be damped, thereby avoiding strong vibration of the device when the bearing rotates, thereby reducing the damage to components caused by vibration and improving the service life of the device.

The utility model is provided with a lubricating oil tank, a time controller, a one-way air outlet valve, a one-way air inlet valve, a micro oil pump, an oil pipe and an oil filling component. The micro oil pump is electrically connected to the time controller. The time controller is a KG316T model time controller, which can accurately set the power-on time and power-on duration of the micro oil pump to the second. By setting the time of the time controller, the micro oil pump can regularly draw lubricating oil from the lubricating oil tank and inject it into the bearing sleeve through the oil pipe to lubricate the bearing. By setting the power-on time of the time controller, the micro oil pump can pump out lubricating oil in a quantitative manner to avoid waste of lubricating oil or insufficient oil.

When the shock absorber spring 7 and the inner rod 11 contract, the piston 8 is pressed down, and the hydraulic oil in the lower oil chamber will flow into the upper oil chamber through the oil hole 9. Since the throttle valve 10 can limit the flow rate of the hydraulic oil, the extension and contraction speed of the inner rod 11 will be reduced, forming a certain telescopic damping, avoiding the shock absorber spring 7 from being compressed too quickly or rebounding too quickly, reducing the rebound impact force of the shock absorber spring 7, and improving the shock absorption effect. The shock-absorbing rubber block 3 can further improve the shock absorption effect of the device and enhance its shock filtering performance. Through the above structure, the device can be damped, thereby avoiding strong vibration of the device when the bearing rotates, thereby reducing the damage to components caused by vibration and increasing the service life of the device.

When the shock-absorbing spring 7 and the inner rod 11 shrink, the piston 8 presses down, and the hydraulic oil in the lower oil chamber will flow into the upper oil chamber through the oil hole 9. Since the throttle valve 10 can limit the flow rate of the hydraulic oil, the extension and contraction speed of the inner rod 11 will be reduced, forming a certain telescopic damping, avoiding the shock-absorbing spring 7 from compressing too fast or rebounding too fast, reducing The rebound impact force of the shock-absorbing spring 7 is reduced, and the shock-absorbing effect is improved.

The micro oil pump 18 is electrically connected to the time controller 15. The time controller 15 is a KG316T model time controller 15, which can accurately set the power-on time and power-on duration of the micro oil pump 18 to seconds.
