[0002] The bearing cover is located on the outside of the gearbox housing, blocking the outer ring of the bearing or the end cover of the bearing bore. It can effectively prevent dust and other foreign objects from entering the raceway of the rolling elements, ensuring that the lubricant only acts on the rolling elements and raceway without overflowing, and to a certain extent preventing damage to the bearing. The bearing cover needs to go through processes such as cutting, drilling, and grinding during processing. Therefore, multiple processing equipment is required for processing. With the advancement of technology, the bearing cover to be processed can be transported by a traveling clamping device and moved to different processing machine tools for processing.

[0003] Inadequacies of existing technology: In the use of existing traveling clamping devices, the machine tools are mostly distributed in a linear shape on one side of the traveling clamping device, which occupies a lot of space and cannot accurately deliver the bearing cover to the machine tool; the existing traveling clamping device is prone to uneven force during movement, causing deflection and affecting the movement accuracy.

[0012] The technical effects and advantages of this utility model are as follows:

[0024] Reference Figures 1 to 6This utility model provides a high-precision intelligent walking clamping device, including a base mechanism 1, and further including: a moving mechanism 2, a robotic arm 3, a fixed gripper 4, a material receiving structure 5, a first processing machine tool 6, a second processing machine tool 7, a third processing machine tool 8, a feeding device 9, and a fourth processing machine tool 10. The second processing machine tool 7, the first processing machine tool 6, the third processing machine tool 8, and the fourth processing machine tool 10 are evenly distributed on both sides of the base mechanism 1, and the feeding device 9 and the material receiving structure 5 are respectively located at both ends of the base mechanism 1. The bottom end of the moving mechanism 2 is movably connected to the top end of the base mechanism 1. The bottom end of the robotic arm 3 is movably sleeved with the top end of the moving mechanism 2, and the robotic arm 3 can rotate in the horizontal plane. The side of the fixed gripper 4 is movably sleeved with the top end of the robotic arm 3, and the fixed gripper 4 is used to grip the bearing cover. The base mechanism 1 includes a base plate 101, and a slide rail 102 is fixedly connected to the top end of the base plate 101. The moving mechanism 2 includes a moving platform 201, and a slide groove 202 is opened at the bottom end of the moving platform 201. The side of the slide groove 202... The moving platform 201 is movably connected to the side of the slide rail 102. During use, the moving platform 201 can move laterally along the slide rail 102 to place the bearing cover to be processed on the feeding device 9. The moving platform 201 moves along the slide rail 102 to one end close to the feeding device 9. The robotic arm 3 rotates at the top of the moving platform 201 to align the fixed gripper 4 with the feeding device 9. The robotic arm 3 drives the fixed gripper 4 to move in the vertical plane to clamp the bearing cover to be processed. The moving mechanism 2 is started again to move the moving platform 201 to the position of the third processing machine tool 8. The robotic arm 3 is adjusted to align the bearing cover to be processed on the fixed gripper 4 with the third processing machine tool 8. The fixed gripper 4 rotates along the robotic arm 3 to place the bearing cover to be processed on the third processing machine tool 8 at a suitable angle for processing. After processing, the moving mechanism 2, the robotic arm 3 and the fixed gripper 4 are used to sequentially place the bearing cover to be processed on the second processing machine tool 7, the first processing machine tool 6 and the fourth processing machine tool 10 for processing. After that, it is placed inside the receiving structure 5 to reduce the space occupied by the equipment.

[0025] The mobile platform 201 has a cavity 208 at its bottom end. A servo motor 207 is fixedly connected to the side of the cavity 208. A worm gear 211 is fixedly connected to the output shaft of the servo motor 207. A transmission shaft 206 is movably sleeved at the top of the cavity 208. A worm wheel 210 is fixedly sleeved on the side of the transmission shaft 206. The side of the worm wheel 210 meshes with the side of the worm gear 211. A transmission gear 205 is fixedly connected to the bottom end of the transmission shaft 206. A mounting plate 103 is fixedly connected to the top of the base plate 101. A gear rack 104 is fixedly connected to the side of the mounting plate 103. The side of the gear rack 104 meshes with the side of the transmission gear 205. The servo motor 207 drives the worm gear 211 to rotate. The meshing of the worm wheel 210 with the worm gear 211 drives the transmission shaft 206 to rotate, thereby driving the transmission gear 205 to rotate. The meshing of the transmission gear 205 with the gear rack 104 drives the mobile platform 201 to move laterally along the slide rail 102.

[0026] The worm gear 211 and the mounting plate 103 are in the same vertical plane as the central axis of the moving platform 201. The gear racks 104 on both sides are symmetrically distributed along the central axis of the moving platform 201, and the slide rails 102 on both sides are symmetrically distributed along the central axis of the moving platform 201. This ensures that the moving platform 201 is subjected to uniform force during movement and avoids deflection, thereby ensuring the stability of the moving platform 201 when moving along the slide rails 102.

[0027] The side of the slide 202 is movably connected to a support wheel 209 via a pin. The bottom end of the support wheel 209 is movably connected to the top end of the slide rail 102. The support wheel 209 supports the moving platform 201. When the moving platform 201 moves along the slide rail 102, the support wheel 209 rolls along the slide rail 102, reducing the friction between the moving platform 201 and the slide rail 102.

[0028] The cleaning plate 203 is fixedly connected to the side of the mobile platform 201 at the position corresponding to the slide rail 202. The bottom end of the cleaning plate 203 is movably connected to the top end of the slide rail 102. When the mobile platform 201 moves, the cleaning plate 203 cleans the surface of the slide rail 102 to prevent debris from adhering to the slide rail 102 and blocking the mobile platform 201.

[0029] The cleaning plate 203 includes a mounting base 2031, the side of which is fixedly connected to the side of the moving platform 201. The bottom end of the mounting base 2031 has a mounting groove 2033, the top end of which is fixedly connected to a pressure spring 2034, and the bottom end of the pressure spring 2034 is fixedly connected to a scraper 2032. The scraper 2032 has a V-shaped structure. The pressure spring 2034 pushes the scraper 2032 downward, so that the bottom end of the scraper 2032 is always in close contact with the top end of the slide rail 102 to avoid gaps.

[0030] The top of the base plate 101 is fixedly connected to a reflective grating 105, and the side of the moving platform 201 is fixedly connected to a capacitive grating sensor 204 corresponding to the position of the reflective grating 105. The capacitive grating sensor 204 reads the reflective grating 105 as the moving platform 201 moves to determine the lateral position of the moving platform 201.

[0031] The working principle of this utility model is as follows: The bearing cover to be processed is placed on the feeding device 9. The servo motor 207 is started to drive the worm gear 211 to rotate. The worm wheel 210 meshes with the worm gear 211 to drive the transmission shaft 206 to rotate, thereby driving the transmission gear 205 to rotate. The transmission gear 205 meshes with the gear rack 104 to drive the moving platform 201 to move laterally along the slide rail 102, so that the slide rail 102 moves to one end close to the feeding device 9. At the same time, during the movement of the moving platform 201, the pressure spring 2034 pushes the scraper 2032 downward, so that the bottom end of the scraper 2032 is always in close contact with the top end of the slide rail 102 to clean the top end of the slide rail 102. The robotic arm 3 rotates at the top of the moving platform 201. Align the fixed gripper 4 with the feeding device 9. The robotic arm 3 moves the fixed gripper 4 in the vertical plane to clamp the bearing cover to be processed. Then, the moving mechanism 2 is activated again to move the moving platform 201 to the position of the third processing machine tool 8. The robotic arm 3 is used to adjust the bearing cover to be processed on the fixed gripper 4 to align with the third processing machine tool 8. The fixed gripper 4 rotates along the robotic arm 3 to place the bearing cover to be processed on the third processing machine tool 8 at a suitable angle for processing. After processing, the moving mechanism 2, the robotic arm 3 and the fixed gripper 4 are used to sequentially place the bearing cover to be processed on the second processing machine tool 7, the first processing machine tool 6 and the fourth processing machine tool 10 for processing. After that, it is placed inside the receiving structure 5 to reduce the space occupied by the equipment.
