Description

Technical Field

[0001] This utility model relates to the field of automotive bearing housing technology, and in particular to a flexible adjustable automotive bearing housing. Background Technology

[0002] Slewing bearing housings are large and extra-large bearing housings with special construction that can accept comprehensive loads. They are characterized by compact construction, sensitive rotation, and convenient installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is commonly referred to as the bearing housing.

[0003] Existing automotive bearing housings can accommodate bearings of different diameters, but they cannot maintain consistent concentricity when installing bearings of different diameters, which can affect transmission efficiency and mating accuracy.

[0004] Therefore, to address the problem that existing automotive bearing housings cannot maintain consistent concentricity when installing bearings of different diameters, which can easily affect transmission efficiency and mating accuracy, a flexible adjustable automotive bearing housing can be designed. By setting an adjusting bolt, when the adjusting bolt is rotated, the front end of the adjusting bolt will drive the turntable to rotate. The groove on the surface of the turntable will push the levers. The four levers will drive the corresponding slides to slide synchronously inside the grooves of the fixed plate, thereby driving the gripper to adjust its position. The concentricity of the gripper will remain unchanged during the movement. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a flexible adjustable automotive bearing housing, including a bearing housing body 1; it also includes a fixed seat 2, an adjusting bolt 3, a turntable 4, a fixed plate 5, a sliding groove 6, a sliding seat 7, a gripper 8, a lever 9, and a slot 10. The fixed seat 2 is installed on the rear side of the inner surface of the mounting hole of the bearing housing body 1. The adjusting bolt 3 is threaded through the rear surface of the fixed seat 2. The turntable 4 is installed on the front surface of the adjusting bolt 3. The fixed plate 5 is installed in the middle of the inner surface of the mounting hole of the bearing housing body 1. The outer surface of the fixed plate 5 has four circumferentially distributed sliding grooves 6, and the inner surface of the sliding grooves 6 slides. A slide block 7 is connected, and a gripper 8 is provided on the outer surface of the slide block 7. A lever 9 is provided on the rear surface of the slide block 7. Four circumferentially distributed slots 10 are opened through the front surface of the turntable 4. The lever 9 is slidably connected to the slots 10. By setting an adjusting bolt 3, when the adjusting bolt 3 is rotated, the front end of the adjusting bolt 3 will drive the turntable 4 to rotate. The slots 10 on the surface of the turntable 4 will push the lever 9. The four levers 9 drive the corresponding slide blocks 7 to slide synchronously inside the sliding grooves 6 of the fixed plate 5, thereby driving the gripper 8 to adjust its position. The concentricity of the gripper 8 remains unchanged during the movement.

[0024] Please see Figures 1-4In this embodiment, symmetrical limit grooves 11 are formed on the side surface of the slide 6. Limit blocks 12 are provided at the corresponding positions of the limit grooves 11 on the slide 7. The limit blocks 12 are slidably connected to the limit grooves 11. One end of a symmetrical spring 13 is installed on the side surface of the slide 6 near the center of the fixed plate 5. The other end of the spring 13 is connected to the slide 7. An anti-slip pad 14 is provided on the inner surface of the gripper 8. By setting the limit blocks 12 and the limit grooves 11, the position of the slide 7 can be restricted, the moving direction of the slide 7 can be maintained, and the clamping accuracy and stability can be improved. In addition, by setting the spring 13, the spring 13 is always kept in a stretched state after installation, so its contraction force will give the slide 7 a pulling force that always points to the center of the fixed plate 5. With the cooperation of the anti-slip pad 14, the clamping effect can be improved. A bottom box 15 is provided on the bottom surface of the bearing seat body 1. A driven gear 16 is rotatably connected at the bottom center of the inner surface of the bottom box 15. A top cover 1 is provided on the upper surface of the bottom box 15. 7. A drive motor 18 is installed on the right side of the bottom surface of the top cover 17. The output end of the drive motor 18 is provided with a drive gear 19, which meshes with a driven gear 16. One end of a rotating shaft 20 is located in the middle of the upper surface of the driven gear 16. The other end of the rotating shaft 20 passes through the top cover 17 and connects to the bottom of the bearing housing body 1. By setting the drive motor 18, its output end will drive the drive gear 19 to rotate during operation. The drive gear 19 will drive the driven gear 16 to rotate, and the driven gear 16 will drive the rotating shaft 20 and the bearing housing body 1 on its upper surface to rotate, thereby realizing the angle adjustment of the bearing housing body 1. Threaded mounting pieces 21 are provided at the corners of the inner surface of the bottom box 15, and fixing screws 22 are provided at the corners of the upper surface of the top cover 17. The top cover 17 is fixed to the threaded mounting pieces 21 by the fixing screws 22. By setting the threaded mounting pieces 21 and the fixing screws 22, it is easy for the staff to disassemble and assemble the top cover 17.

[0025] Please see Figures 1-5In this embodiment, an annular groove 23 is provided on the upper surface of the top cover 17, and arc-shaped blocks 24 are symmetrically arranged on the left and right sides of the bottom surface of the bearing seat body 1. The arc-shaped blocks 24 are slidably connected to the annular groove 23. By setting the arc-shaped blocks 24, when the bearing seat body 1 rotates, the arc-shaped blocks 24 will slide inside the annular groove 23, thereby improving the rotational stability of the bearing seat body 1. A knob 25 is provided on the rear surface of the adjusting bolt 3, and an insertion hole 26 is provided through the upper surface of the knob 25. The knob 25 facilitates the adjustment by the operator. Bolt 3 is rotated, and through the opening of the insertion hole 26, the operator can insert the tool into the insertion hole 26 and use the lever principle to rotate the knob 25 with less effort. An auxiliary gear 27 is provided on the rear surface of the knob 25, and a motor mounting plate 28 is installed at the lower position of the rear surface of the bearing housing body 1. By setting the auxiliary gear 27, the operator can add an external motor and a gear that meshes with the auxiliary gear 27 through the motor mounting plate 28, thereby driving the auxiliary gear 27 to rotate and realizing automatic control of the clamping operation of the gripper 8.

[0026] During operation, the position of the slide 7 can be restricted by setting the limit block 12 and the limit groove 11, maintaining the movement direction of the slide 7 and improving clamping accuracy and stability. Furthermore, by setting the spring 13, which remains in a stretched state after installation, its contraction force provides the slide 7 with a pulling force that always points towards the center of the fixed plate 5. Combined with the anti-slip pad 14, this improves the clamping effect. By setting the drive motor 18, its output end drives the drive gear 19 to rotate during operation. The drive gear 19 drives the driven gear 16 to rotate, which in turn drives the rotating shaft 20 and the bearing seat body 1 on its upper surface to rotate, thereby achieving angle adjustment of the bearing seat body 1. This is achieved by setting the thread... The mounting plate 21 and fixing screw 22 facilitate the disassembly and assembly of the top cover 17 by the operator. By setting the arc block 24, when the bearing housing body 1 rotates, the arc block 24 will slide inside the annular groove 23, thereby improving the rotational stability of the bearing housing body 1. By setting the knob 25, the operator can easily turn the adjusting bolt 3. By opening the insertion hole 26, the operator can insert the tool into the insertion hole 26 and use the lever principle to turn the knob 25 with less effort. By setting the auxiliary gear 27, the operator can add an external motor and a gear meshing with the auxiliary gear 27 through the motor mounting plate 28, thereby driving the auxiliary gear 27 to rotate and realizing automatic control of the gripper 8 clamping operation.

[0027] Through the above steps, by setting the adjusting bolt 3, when the adjusting bolt 3 is rotated, the front end of the adjusting bolt 3 will drive the turntable 4 to rotate. The groove 10 on the surface of the turntable 4 will push the lever 9. The four levers 9 will drive the corresponding slide 7 to slide synchronously inside the slide groove 6 of the fixed plate 5, thereby driving the gripper 8 to adjust its position. During the movement of the gripper 8, the concentricity will remain unchanged. This solves the problem that existing automotive bearing housings cannot keep the concentricity of bearings of different diameters consistent when installing bearings of different diameters, which can easily affect transmission efficiency and docking accuracy.
