Description

TECHNICAL FIELD

[0001] The application relates to the technical field of bearing positioning detection, in particular to a bearing positioning detection device with inner and outer diameter positioning functions. BACKGROUND

[0002] With the rapid development of the new energy automobile industry, the precision requirements of plug-in hybrid drive, pure electric drive and fuel cell drive new energy automobiles for core components are increasingly stringent. Bearings, as key components in automobile transmission systems, steering systems and motors, directly affect the automobile power transmission efficiency, driving stability and service life in terms of inner and outer diameter size precision, roundness and assembly adaptability. In the production and quality inspection links of new energy automobile bearings, professional detection devices are needed to accurately position the inner and outer diameters of the bearings, so as to ensure the accuracy of subsequent size detection and performance test data and meet the high reliability requirements of new energy automobiles for components. However, the existing bearing positioning detection devices have many technical defects when adapting to new energy automobile bearing detection scenarios: firstly, the positioning structure has poor adaptability. Traditional devices mostly use rigid clamping components with fixed sizes, which are difficult to adapt to the size differences of the inner and outer diameters of bearings of different specifications, and are prone to problems such as "loose clamping leading to positioning deviation" or "tight clamping damaging the surface of the bearing". Especially for thin-walled precision bearings used in new energy automobile motors, traditional positioning methods are prone to cause bearing deformation, affecting detection accuracy and subsequent use performance of the bearing. Secondly, the inner and outer diameter positioning is not synchronized. Most devices need to manually adjust the outer diameter and inner diameter positioning mechanisms separately, which takes a long time and manual operation is prone to cause misalignment of the inner and outer diameter positioning references, resulting in large deviations between the size data collected by the detector and the actual parameters of the bearing, which cannot meet the high standard requirements of new energy automobile bearings for detection accuracy. Thus, the detection accuracy and efficiency are reduced. SUMMARY

[0009] Preferably, the fixing assembly comprises: a short plate installed on the top of the fixed block, a rotating rod rotatably connected to the inner side of the short plate, a plug plate installed on the outer side of the rotating rod, a plug strip installed on the bottom of the plug plate, a toothed plate installed on the top of the sliding block, and the plug strip being inserted into the top of the toothed plate.

[0013] Preferably, the cross section of the insertion bar is triangular, and the inner side of the clamping rod and the swing rod is L-shaped.

[0014] (Three) beneficial effects

[0015] Compared with the prior art, the bearing positioning detection device with inner and outer diameter positioning functions has the following beneficial effects:

[0016] 1. The bearing positioning detection device with inner and outer diameter positioning functions, by means of the setting of the movable assembly, the driving motor is operated to drive the threaded rod to rotate, thereby driving the rotating disc to rotate, the rotating disc guides the sliding rod to slide, the radially contracted movable plate is hingedly connected, the connecting plate drives the clamping ring to approach the bearing outer diameter, the adjusting ring in the clamping ring slides to compensate, the outer diameter is ringed and positioned, at the same time, the trigger ring and the trigger rod of the rotating disc are synchronously rotated, the threaded rod also drives the moving strip to move axially, so that the sliding block and the connecting ring slide, until the groove of the rotating ring contacts with the trigger rod, the trigger rod drives the rotating ring to rotate, the movable block pushes the abutting rod and the clamping rod to open, the adjusting rod is compressed to compensate when the inner diameter deviation occurs, so as to prevent the positioning deviation and the insufficient adaptation, improve the precision efficiency, protect the bearing and enhance the adaptability.

[0017] 2. This bearing positioning and detection device with inner and outer diameter positioning function utilizes a fixed assembly. The rotating rod inside the short plate at the top of the fixed block rotates under the elastic force of the spiral spring, causing the insert plate to swing downwards. This allows the insert strip at the bottom of the insert plate to insert into the toothed groove of the toothed plate at the top of the sliding block. When the sliding block slides, it causes the toothed plate to slide. The toothed plate first contacts the insert strip, causing the insert plate to swing upwards via the rotating rod. After positioning is completed, the rotating rod resets under the action of the spiral spring, and the insert strip re-inserts into the toothed plate for fixation. The triangular insert strip and the toothed plate form a one-way lock, restricting the reverse sliding of the sliding block, fixing the position of the connecting ring and the clamping rod, preventing the inner diameter positioning structure from loosening and the sliding block from being accidentally displaced due to external interference, thus improving positioning stability and ensuring the inner diameter positioning accuracy. 3. This bearing positioning and detection device with inner and outer diameter positioning function utilizes the setting of the moving component. The rotation of the threaded rod drives the rotating shaft to rotate within the limiting ring, and the locking rod rotates synchronously with the rotating shaft. At this time, the swing rod of the moving component is in contact with the limiting block under the action of the torsion spring. There is a gap between its L-shaped inner side and the rotation trajectory of the locking rod, and the rotation direction of the locking rod is opposite to the locking trigger direction of the swing rod. Therefore, the locking rod only moves in a circular motion and does not contact and engage with the swing rod. If the threaded rod accidentally rotates in the opposite direction, it will drive the rotating shaft and the locking rod to rotate in the opposite direction. The swing rod will be in contact with the limiting block, and its L-shaped inner side will gradually coincide with the reverse rotation trajectory of the locking rod. After the locking rod continues to rotate, its L-shaped end face contacts the swing rod and applies force, pushing the swing rod to swing. The L-shaped structure of the two is completely engaged, forming a one-way lock, restricting the reverse rotation of the locking rod and the threaded rod, avoiding deviation of the moving component, and ensuring the stability of the device.

[0037] Working principle, the bearing positioning detection device with inside and outside diameter positioning function, with detection table 1 as the basis support, through the controller 2 overall regulation and control the coordinated operation of movable assembly 6, fixed assembly 7, moving assembly 8 and detector 3, realize the accurate positioning of bearing inside and outside diameter and subsequent detection, before the device starts, movable assembly 6 is in the initial reset state: clamping ring 66 is in the open state, clamping rod 614 is retracted in the inside of connecting ring 610; In fixed assembly 7, under the initial elastic force of volute spring 76, insert strip 74 is not engaged with toothed plate 75;In the mobile assembly 8, the swing lever 82 is attached to the limiting block 84 under the action of the torsional spring 83, and the clamping rod 86 is not locked with the swing lever 82. The operator places the bearing to be detected at the center of the fixed disc 61, sets the positioning parameters and detection mode through the controller 2, starts the device, and the driving motor 616 is energized and rotates to drive the threaded rod 615 to start rotating, and formally enters the positioning process. When the threaded rod 615 rotates, it drives the rotating disc 62 fixed thereto to rotate on the surface of the fixed disc 61. The arc-shaped groove 6200 opened on the surface of the rotating disc 62 forms a guiding action on the sliding rod 63. With the rotation of the rotating disc 62, the sliding rod 63 slides along the arc-shaped groove 6200. The hinged moving plate 64 is dragged by the sliding rod 63, and shrinks along the radial direction of the fixed disc 61. The moving plate 64 drives the clamping ring 66 to move synchronously to the outside of the bearing through the connecting plate 65, until the inside of the clamping ring 66 contacts with the outer diameter of the bearing. If there is a slight size deviation in the outer diameter of the bearing, the adjusting ring 67 slidably connected inside the clamping ring 66 will be adjusted along the inner wall of the clamping ring 66 under the action of the contact pressure, and the size difference will be compensated by the sliding of the adjusting ring 67 itself, to ensure that the adjusting ring 67 is tightly attached to the outer diameter of the bearing, and the ring-shaped positioning of the outer diameter of the bearing is completed. At the same time, the trigger ring 620 and the trigger lever 621 on the surface of the rotating disc 62 rotate synchronously with the rotating disc 62, to prepare for the synchronous completion of the inner diameter positioning. While the threaded rod 615 rotates, the moving strip 617 connected with the surface threads of the threaded rod 615 moves axially outward along the threaded rod 615, drives the sliding block 69 fixed at the bottom to slide inside the fixed block 68, and the connecting ring 610 on the outside of the sliding block 69 slides towards the surface of the trigger ring 620, until the recess 6110 opened in the rotating ring 611 moves to the surface of the trigger lever 621. At this time, the rotation of the trigger ring 620 and the trigger lever 621 drives the rotating ring 611 to rotate inside the connecting ring 610. The rotating ring 611 inside is hinged to the movable block 612, which rotates with the rotating ring 611 to change the angle, drives the abutting lever 613 connected therewith to open outward around the hinge point on the surface of the connecting ring 610, and the clamping lever 614 outside the abutting lever 613 expands outward synchronously with the abutting lever 613, until the adjusting lever 618 outside the clamping lever 614 contacts with the inner diameter of the bearing. If there is a size deviation in the inner diameter of the bearing, the adjusting lever 618 is compressed by the contact pressure of the fixed spring 619 inside, and the size difference is compensated by the elastic deformation of the fixed spring 619, so that the adjusting lever 618 always maintains stable abutment with the inner diameter of the bearing, and the supporting positioning of the inner diameter of the bearing is realized. When the controller 2 determines that the inner and outer diameter positioning is completed, the driving motor 616 is temporarily stopped, and the inner and outer diameters of the bearing are positioned through the movable assembly 6, which can prevent detection errors caused by bearing positioning deviation and positioning failure caused by insufficient size deviation adaptation, improve detection accuracy and efficiency, protect the bearing to be detected from damage, and enhance the adaptability of the device to bearings of different specifications, laying a stable foundation for the subsequent fixing and detection process.

[0038] After the inner and outer diameters are positioned, the fixing component 7 initiates the locking process. Inside the short plate 71 at the top of the fixing block 68, the rotating rod 72 automatically rotates under the release force of the spiral spring 76, causing the outer insert plate 73 to swing downwards. The insert strip 74 at the bottom of the insert plate 73 swings along with the insert plate 73, gradually approaching the toothed plate 75 at the top of the sliding block 69, and finally inserting into the toothed groove of the toothed plate 75. When the sliding block 69 slides, it also causes the toothed plate 75 mounted on top to slide. When the toothed plate 75 slides, it first abuts against the surface of the insert strip 74, and this contact causes the insert plate 73 to swing upwards via the rotating rod 72. Once positioning is complete... Afterwards, the rotating rod 72 will reset under the action of the spiral spring 76, so that the insert plate 73 and the insert strip 74 are re-inserted into the top of the toothed plate 75 for fixation. The triangular insert strip 74 and the tooth groove of the toothed plate 75 form a one-way locking structure, which restricts the sliding block 69 from sliding in the opposite direction, thereby fixing the position of the connecting ring 610 and the clamping rod 614. This prevents the inner diameter positioning structure from loosening during the detection process and from being accidentally displaced by external interference, such as slight vibration of the detection table 1 or indirect force when the detector 3 moves. This improves the stability and reliability of the inner and outer diameter positioning state and ensures that the bearing inner diameter positioning accuracy does not deviate during the detection process.

[0039] Before the device starts and during the positioning of the inner and outer diameters of the bearing, the rotation of the threaded rod 615 synchronously drives the rotation of the rotating shaft 85 fixedly connected with the threaded rod 615 inside the limiting ring 81, and the clamping rod 86 outside the rotating shaft 85 rotates synchronously with the rotating shaft 85. At this time, the swinging rod 82 in the moving assembly 8 is always tightly fitted inside the limiting block 84 under the initial elastic force of the torsional spring 83, the L-shaped inside of the swinging rod 82 keeps a certain gap with the rotating track of the clamping rod 86, and the rotating direction of the clamping rod 86 is opposite to the locking trigger direction of the swinging rod 82. During the positioning stage, the threaded rod 615 rotates forward, and the rotating direction of the clamping rod 86 will push the swinging rod 82 to overcome the elastic force of the torsional spring 83. Therefore, when the clamping rod 86 rotates with the rotating shaft 85, it will only make a circular motion along its own rotating track and will not come into contact or engagement with the swinging rod 82. When the threaded rod 615 reversely rotates due to unexpected circumstances, it will synchronously drive the reverse rotation of the rotating shaft 85 fixedly connected with the threaded rod 615 inside the limiting ring 81, and the clamping rod 86 outside the rotating shaft 85 reversely rotates with the rotating shaft 85. At this time, the swinging rod 82 in the moving assembly 8 is still tightly fitted inside the limiting block 84 under the initial elastic force of the torsional spring 83, and the L-shaped inside of the swinging rod 82 gradually coincides with the reverse rotating track of the clamping rod 86. With the continuous reverse rotation of the clamping rod 86, the end face of the L-shaped structure of the clamping rod 86 will come into contact with the L-shaped inside wall of the swinging rod 82 and apply a pushing force to the swinging rod 82 rotating around the hinge joint. Since the direction of the pushing force is opposite to the elastic force of the torsional spring 83, and the size of the pushing force is greater than the initial elastic force of the torsional spring 83, the swinging rod 82 will be pushed to swing towards the limiting block 84 around the hinge joint with the limiting ring 81. The L-shaped structure of the clamping rod 86 is fully engaged with the L-shaped structure of the swinging rod 82, and the L-shaped inside of the swinging rod 82 will be tightly in contact with the L-shaped outside of the clamping rod 86 through the resistance of the limiting block 84, forming a one-way locking structure. This structure directly limits the continuous reverse rotation of the clamping rod 86, and further limits the reverse displacement of the threaded rod 615 through the rotating shaft 85, avoiding the deviation of the movable assembly 6 due to the accidental reverse rotation of the threaded rod 615, such as the accidental opening of the clamping ring 66 and the contraction of the clamping rod 614, ensuring the stability of the device during standby or positioning, and preventing the accidental reverse rotation from damaging the positioning state of the bearing or affecting the subsequent detection accuracy.
