Technical Field

[0001] This utility model belongs to the field of bearing testing technology, specifically relating to a three-channel measurement and sorting device for bearing testing. Background Technology

[0002] The main function of wheel hub bearings is to bear weight and provide precise guidance for the rotation of the wheel hub. They bear both axial and radial loads, making them a very important component. After the wheel hub bearings are manufactured, their inner and outer diameters, as well as cracks in the inner wall and the relative dimensions of their internal grooves, need to be inspected.

[0003] Currently, bearing measurement cannot perform rapid loading and unloading operations, which reduces the efficiency of loading, unloading, and sorting. At the same time, it is impossible to quickly position bearings of different specifications, and the deviation during detection is easy to affect the detection effect. To address this, we propose a three-channel measurement and sorting device for bearing detection. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a three-channel measuring and sorting device for bearing testing, including a base 4, a testing platform 5 mounted on the base 4, three sets of feeding conveyor belts 2 mounted on the testing platform 5, three sets of bearing positioning structures 3 mounted on one side of the testing platform 5 of the feeding conveyor belts 2, and three sets of unloading conveyor belts 6 mounted on the other side of the testing platform 5. A top frame 7 is also mounted on the base 4, with feeding mechanisms 1 corresponding to the three sets of feeding conveyor belts 2 mounted on the top frame 7. Simultaneously, an unloading and sorting mechanism 8 corresponding to the three sets of unloading conveyor belts 6 is also mounted on the other side of the top frame 7. The top frame 7 also includes... The testing mechanism 9 is used to measure the bearings; the feeding mechanism 1 and the unloading sorting mechanism 8 are symmetrically arranged on the top frame 7, and the feeding mechanism 1 and the unloading sorting mechanism 8 have the same structure; the feeding mechanism 1 includes a cross frame 11, which is arranged on the top frame 7. A groove 17 is provided at the bottom of the cross frame 11, and a transverse lead screw 18 is rotatably arranged in the groove 17. One end of the transverse lead screw 18 is connected to the output shaft of the drive motor 12. A lead screw nut 19 is provided on the transverse lead screw 18, and one end of the lead screw nut 19 is connected to the mounting platform 13, which can adjust the transverse position of the mounting platform 13.

[0024] A telescopic cylinder 14 is installed at the bottom of the mounting platform 13. A horizontal arm 15 is installed at one end of the piston rod of the telescopic cylinder 14. A clamping assembly 16 for positioning the bearing is installed on the horizontal arm 15, and the height of the clamping assembly 16 can be adjusted.

[0025] The clamping assembly 16 includes a positioning sleeve 161, which is disposed on one side of the cross arm 15. A hydraulic cylinder 162 is disposed on the top of the positioning sleeve 161. A conical wedge 163 is disposed on the piston rod of the hydraulic cylinder 162. A clamping part is also disposed inside the positioning sleeve 161, which moves synchronously with the conical wedge 163. This part can move the clamping arm in opposite directions and clamp and fix the inner hole of the bearing. The clamping part includes a first semi-cylindrical clamping arm 169 and a second semi-cylindrical clamping arm 170. A first connecting rod 166 is disposed at one end of the first semi-cylindrical clamping arm 169, and a second connecting rod 171 is disposed at one end of the second semi-cylindrical clamping arm 170. A first wedge 164 is disposed at the end of the first connecting rod 166, and a second wedge 173 is disposed at the end of the second connecting rod 171. This part can synchronously control the first semi-cylindrical clamping arm 169 and the second semi-cylindrical clamping arm 170 to move in opposite directions.

[0026] First, the bearing to be inspected is conveyed by the feeding conveyor belt 2. The telescopic cylinder 14 drives the horizontal arm 15 to move, which in turn moves the clamping assembly 16, inserting the first semi-cylindrical clamping arm 169 and the second semi-cylindrical clamping arm 170 into the inner hole of the bearing. The hydraulic cylinder 162 drives the conical wedge 163 to move, simultaneously moving the first wedge 164 and the second wedge 173 in opposite directions. The first wedge 164 moves the first connecting rod 166, and the second wedge 173 moves the second connecting rod 171. The first connecting rod 166 and the second connecting rod 171 then move the first semi-cylindrical clamping arm 169 and the second semi-cylindrical clamping arm 170 in opposite directions. When the first semi-cylindrical clamping arm 169 and the second semi-cylindrical clamping arm 170 are in contact with the inner hole of the bearing... After the holes are aligned, the first semi-cylindrical clamping arm 169 and the second semi-cylindrical clamping arm 170 fix the bearing. Then, the drive motor 12 drives the transverse lead screw 18 to rotate, and the lead screw nut 19 drives one end of the mounting platform 13. The mounting platform 13 drives the horizontal arm 15 to move through the telescopic cylinder 14. The horizontal arm 15 drives the bearing to move to the bearing positioning structure 3. Then, the hydraulic cylinder 162 separates the conical wedge 163 from the first wedge 164 and the second wedge 173. Then, the first semi-cylindrical clamping arm 169 and the second semi-cylindrical clamping arm 170 separate from the bearing. Then, the bearing is inspected by the detection mechanism 9. After the inspection is completed, the bearing is unloaded onto the unloading conveyor belt 6 through the unloading sorting mechanism 8. The unloading conveyor belt 6 transfers the bearing, and the operator can classify the qualified bearings from the unqualified bearings.

[0027] Furthermore, a first spring 165 is provided on one side surface of the first connecting rod 166, and a second spring 172 is provided on one side surface of the second connecting rod 171. When the first connecting rod 166 and the second connecting rod 171 move, the first connecting rod 166 and the second connecting rod 171 compress the first spring 165 and the second spring 172. Through the elastic force of the first spring 165 and the second spring 172, the first connecting rod 166 and the second connecting rod 171 can be driven to reset and move.

[0028] Furthermore, the testing mechanism 9 includes a second electric push rod, on which a flaw detection probe is mounted. The height of the flaw detection probe can be adjusted by extending or retracting the second electric push rod, and the flaw detection probe can detect cracks or fissures in the bearing.

[0029] Furthermore, guide rods 168 are provided on both the first connecting rod 166 and the second connecting rod 171. The guide rods 168 are movably disposed in the guide grooves 167, which are disposed on both sides of the inner surface of the positioning sleeve 161, and can guide the movement of the first connecting rod 166 and the second connecting rod 171.

[0030] Please see Figure 5 The bearing positioning structure 3 includes a support platform 31, which has three sets of positioning rods 33 at equal intervals. Each positioning rod 33 has an adjustment block 34 at its bottom. The adjustment blocks 34 are movably mounted in adjustment grooves 35, which are mounted on the support platform 31. A first electric push rod 32 is also mounted in the adjustment grooves 35, which can synchronously adjust the spacing of the three sets of positioning rods 33 and enable rapid positioning of bearings of different specifications.

[0031] According to the bearing specifications, the spacing of the three sets of positioning rods 33 can be adjusted synchronously, and the three sets of first electric push rods 32 can be operated synchronously. The first electric push rods 32 synchronously drive the adjusting block 34 to move in the adjusting groove 35. The adjusting block 34 drives the positioning rods 33 to move and adjusts the spacing of the three sets of positioning rods 33. By having the three sets of positioning rods 33 fit against the outer surface of the bearing, bearings of different specifications can be positioned.
