[0024] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0025] Please refer to the bearing lubrication and maintenance fixture for the three-dimensional parking frame described in this specific embodiment. Figure 1-4 It includes: a processing table 1, a limiting drive mechanism 2 for clamping bearings of different sizes is installed on the upper surface of the processing table 1, and an oil injection mechanism 3 is provided on one side of the limiting drive mechanism 2.

[0026] The limit drive mechanism 2 includes a support base 201 mounted on the upper surface of the processing table 1. A first sliding seat 202 and a second sliding seat 208 are slidably connected to the upper surface of the support base 201. A plurality of drive wheels 203 are rotatably connected to the surface of the first sliding seat 202, and the plurality of drive wheels 203 are rotatably connected by a drive belt 204. Two auxiliary rollers 209 are rotatably connected to the surface of the second sliding seat 208. A clamping seat 212 is mounted on the upper surface of the support base 201 and between the first sliding seat 202 and the second sliding seat 208. A plurality of inner clamping blocks 213 are slidably connected to the surface of the clamping seat 212.

[0027] The oil injection mechanism 3 includes a third sliding seat 301 slidably connected to the upper surface of the processing table 1, a fourth sliding seat 302 slidably connected to the surface of the third sliding seat 301, a fifth sliding seat 303 slidably connected to the surface of the fourth sliding seat 302, an oil injection bottle 304 mounted on the surface of the fifth sliding seat 303, and an oil injection valve head 305 mounted on the surface of the oil injection bottle 304.

[0028] Through the above technical solution, the design of the inner clamping block 213 allows the tooling to clamp the bearing from the inside, and the relative movement of the first sliding seat 202 and the second sliding seat 208 can handle various types of bearings. The oil bottle 304 and the oil valve head 305 move on the surface of the fourth sliding seat 302 and the fifth sliding seat 303, and under the action of the drive wheel 203 and the drive belt 204, the grease filling rate of the bearing is improved, avoiding the local gaps in traditional manual oiling.

[0029] A first servo motor 205 is mounted on the surface of the first sliding seat 202, and the output shaft of the first servo motor 205 is fixedly connected to a drive wheel 203. The first servo motor 205 drives the drive wheel 203 to rotate, and transmits power through the drive belt 204 to drive the bearing to rotate at a uniform speed. The first servo motor 205 precisely controls the speed to avoid uneven grease distribution caused by speed fluctuations and improve lubrication uniformity.

[0030] Two first electric cylinders 206 are installed on the upper surface of the first sliding seat 202. A cleaning roller 207 is fixedly connected to the surface of the piston rod of the first electric cylinder 206. The first electric cylinder 206 pushes the cleaning roller 207 to roll along the surface of the drive wheel 203 to remove old grease and impurities. Automated cleaning reduces manual intervention. The pressure on the contact surface between the cleaning roller 207 and the drive wheel 203 is controllable to avoid damage to the sealing structure.

[0031] A double-threaded lead screw 210 is rotatably connected to the surface of the support base 201, and the first sliding seat 202 and the second sliding seat 208 are both threaded to the surface of the double-threaded lead screw 210. A second servo motor 211 is mounted on the surface of the support base 201, and the output shaft of the second servo motor 211 is fixedly connected to one end of the double-threaded lead screw 210. The second servo motor 211 drives the double-threaded lead screw 210 to rotate, and synchronously adjusts the distance between the first sliding seat 202 and the second sliding seat 208. The double-threaded structure achieves symmetrical displacement, quickly adapts to different bearing outer diameters, and improves tooling compatibility.

[0032] The clamping base 212 is equipped with a third servo motor 214. The output shaft of the third servo motor 214 is fixedly connected to a transmission threaded seat 215. The upper surface of the transmission threaded seat 215 is threadedly connected to the bottom of multiple inner clamping blocks 213. The third servo motor 214 drives the transmission threaded seat 215 to rotate, which drives the inner clamping blocks 213 to move radially and clamp the inner ring of the bearing. The threaded transmission provides high-precision clamping force control to avoid excessive tightness that could cause bearing deformation.

[0033] The upper surface of the third sliding seat 301 is equipped with a second electric cylinder 306 for horizontal adjustment, and the piston rod of the second electric cylinder 306 is fixedly connected to the fourth sliding seat 302. The second electric cylinder 306 pushes the fourth sliding seat 302 to move horizontally, adjusting the horizontal position of the oil injection valve head 305. Horizontal adjustment avoids misalignment of the oil injection hole.

[0034] The surface of the fourth sliding seat 302 is equipped with a third electric cylinder 307 for longitudinal adjustment, and the piston rod of the third electric cylinder 307 is fixedly connected to the fifth sliding seat 303. The third electric cylinder 307 drives the fifth sliding seat 303 to move longitudinally, adjusting the vertical height of the oil injection valve head 305. The longitudinal adjustment is adapted to different bearing thicknesses.

[0035] Its working principle is as follows:

[0036] Through the above technical solution, in the limit drive mechanism 2, the support base 201 is linked with the second servo motor 211 through the double threaded screw 210, driving the first sliding seat 202 and the second sliding seat 208 to move symmetrically. The inner clamping block 213 of the clamping seat 212 radially clamps the inner ring of the bearing under the control of the third servo motor 214, forming a stable fixation. The drive wheel 203 is driven by the first servo motor 205, and transmits power through the drive belt 204 to make the bearing rotate at a uniform speed, ensuring that the grease is evenly distributed. The cleaning roller 207 is pushed by the first electric cylinder 206 and rolls along the surface of the drive belt 204 to remove old grease and impurities. The oil injection mechanism 3 achieves three-dimensional positioning through the second electric cylinder 306 and the third electric cylinder 307. The oil injection valve head 305 accurately connects to the bearing oil injection hole to improve the grease filling rate. During the oil injection process, the bearing rotation and the oil injection action are synchronized. When the grease overflows from the sealing lip, it automatically stops to avoid excessive oil injection.

[0037] It should be noted that, although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
