Description

Technical Field

[0001] The utility model relates to the technical field of joint bearing installation, in particular to a joint bearing installation mechanism. Background Art

[0002] Spherical bearing is a spherical sliding bearing, whose sliding contact surface is an inner sphere and an outer sphere. It can rotate and swing at any angle during movement. It is widely used in engineering hydraulic cylinders, forging machines, engineering machinery, automation equipment, automobile shock absorbers, water conservancy machinery and other industries. In the production and processing of spherical bearings, spherical bearing installation mechanisms are often used to press the inner ring of the spherical bearing into the outer ring.

[0003] The publication number authorized by China is CN209698401U, and the patent is named a joint bearing installation device. The device includes a hydraulically driven press located above and a workpiece base below the press. The workpiece base includes a manual self-centering four-jaw chuck A, and the axis direction of the manual self-centering four-jaw chuck A is in the vertical direction. A positioning rod is fixedly connected to each of the four jaws of the manual self-centering four-jaw chuck A. The end of the push rod of the press is fixedly connected to the manual self-centering four-jaw chuck B, and each of the four jaws of the manual self-centering four-jaw chuck B is fixedly connected to a pressure rod, and a pressure head is connected to the end of the pressure rod. The lower end face of each pressure head is a plane, and the lower end face of each pressure head is at the same horizontal height. The four pressure heads above are staggered in the circumferential direction with the four positioning rods below. The device has a simple structure and high precision and safety.

[0004] Although the above device has a simple structure, it still has some problems when used:

[0005] 1. The device does not have a radial limit mechanism. When the press is running, the push rod may be easily deflected due to the uneven contact surface of the workpiece, the reaction force of the workpiece, etc.

[0006] 2. The device does not have a shielding mechanism. When the workpiece collapses or breaks due to pressure, the workpiece or workpiece fragments can easily be ejected and injure surrounding personnel.

[0007] In view of the above situation, technical innovation is carried out on the basis of the existing spherical bearing installation mechanism. Utility Model Content

[0008] The purpose of the utility model is to provide a spherical bearing installation mechanism 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 joint bearing mounting mechanism, comprising a mounting seat and a hydraulic cylinder, a limiting sleeve is fixed inside the mounting seat, and an oil storage tank 1 is provided at the top end of the inner wall of the limiting sleeve, an oil storage tank 2 is provided at the bottom end of the inner wall of the limiting sleeve, and the top of the oil storage tank 2 is connected to a channel, an oil filling port is provided at one end of the top wall of the limiting sleeve, and the limiting sleeve is internally slidably connected to a limiting column, the hydraulic cylinder is fixed to one side of the bottom end of the mounting seat, and a pressure block is fixed to the bottom end of the hydraulic cylinder, an upper mold is fixed to the bottom end of the pressure block, a column is fixed on the side of the bottom end of the mounting seat away from the hydraulic cylinder, and a base is fixed to the bottom end of the column, a pressure platform is fixed to the inner side of the top wall of the base, and a lower mold is fixed to the top of the pressure platform.

[0012] Furthermore, a shielding plate is fixed to the top of the electric slider, and an observation window is fixed inside the outer wall of the shielding plate.

[0013] Furthermore, there are multiple observation windows, and the observation windows are made of tempered glass.

[0014] Furthermore, support components are provided on both left and right sides of the bottom end of the base, and the support components include support feet and anti-skid pads, and the bottom ends of the support feet are fixed with anti-skid pads.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: the device is provided with a radial limiting mechanism, which can radially limit the pressing mechanism, thereby preventing the hydraulic cylinder from being deflected due to the reaction force of the workpiece or the uneven surface of the workpiece during the pressing process, which is beneficial to improving the practicality of the device.

When the hydraulic cylinder is extended and contracted, the limit sleeve and the limit column can limit the pressure block to ensure that the pressure block can go straight up and down, thereby ensuring that the output end of the hydraulic cylinder can always go straight up and down, avoiding the pressure block contacting the hydraulic cylinder. The inclined surface causes the pressure block and the hydraulic cylinder to deflect. The oil storage tank 1 and the oil storage tank 2 are connected by a channel. The user can regularly add lubricating oil to the oil filling port. The lubricating oil is filled in the oil storage tank 1 and the oil storage tank 2, which can provide lubrication for the limit column during the lifting and lowering process of the limit column and reduce the resistance between the limit column and the limit sleeve. Through the above structure, the device can radially limit the pressing mechanism to avoid the hydraulic cylinder deflection caused by the reaction force of the workpiece or the uneven surface of the workpiece during the pressing process, which is beneficial to improve the practicability of the device.

[0017] 2. The utility model is provided with a base, an electric slide, an electric slider, a limit slide, a limit slider, a shielding plate and an observation window. When the device is used to install the joint bearing, the user can operate the electric slide to raise the electric slider. When the electric slider is raised, it can lift the shielding plate. The top view cross section of the shielding plate is C-shaped, which can effectively protect the three sides of the device. The column can block the side that the shielding plate cannot cover. The limit slide and the limit slider can prevent the shielding plate from tilting during the lifting process. The shielding plate is made of aluminum alloy. The device has a light texture and high hardness. When the workpiece flies or breaks during the operation of the device, the shielding plate can effectively block the flying workpiece and fragments to prevent them from injuring the surrounding personnel. The observation window is made of plexiglass. The staff can observe the working condition of the device through the observation window. The material has good tensile and impact resistance, which can effectively prevent it from breaking after impact. Through the above structure, it can provide shielding during the operation of the device, thereby preventing the flying fragments from injuring nearby personnel when the workpiece breaks, which is beneficial to improving the safety of the device.
