Description

Technical Field

[0001] This application relates to the technical field of testing machinery, and in particular to a bearing ring testing device. Background Technology

[0002] Bearing rings are a crucial component of bearings. As a high-precision component, the bearing rings require high precision during manufacturing, and their machining quality directly affects the precision, service life, and performance of the finished bearing.

[0003] In related technologies, the manufacturing process of bearing rings typically begins with cylindrical bars or tubes as raw materials. These materials are then forged to form bearing ring blanks. The bearing ring blanks are then heat-treated to improve their hardness and wear resistance. Finally, the heat-treated bearing rings are polished to form the finished bearing rings.

[0004] In the aforementioned technology, after the bearing rings are ground, the grinding precision needs to be checked to eliminate defective bearing rings that do not meet production standards. However, the grinding process for bearing rings involves steps such as chamfering the outer ring, drilling the inner ring, and grooving the inner ring. Therefore, the inspection of bearing rings is usually carried out by first inspecting the outer rings of a batch, and then inspecting the inner rings after they pass the outer ring inspection. Finally, the grooves on the inner rings are inspected. This batch-by-batch elimination method requires a large construction site and requires multiple transfers of bearings during the inspection process, increasing the probability of damage due to collisions during transfer. Summary of the Invention

[0005] To simplify the inspection process of bearing rings and improve inspection efficiency, this application provides a bearing ring inspection device.

[0006] This application provides a bearing ring testing device, which adopts the following technical solution:

[0007] A bearing ring inspection device includes a frame with a conveyor track on the frame. After grinding, the bearing rings enter the conveyor track. The frame is equipped with a quality inspection mechanism for inspecting the bearing rings within the conveyor track. The quality inspection mechanism includes:

[0008] The first quality inspection plate is set on the conveying track. The first quality inspection plate has a quality inspection hole, and the vertical cross-sectional shape of the quality inspection hole is consistent with the vertical cross-sectional shape of the outer ring of the standard bearing race.

[0009] The second quality inspection column is slidably installed on the conveying track along the width direction of the conveying track, and the diameter of the second quality inspection column is the same as the diameter of the inner ring of the bearing sleeve;

[0010] The second drive cylinder is mounted on the frame and connected to the second quality inspection column;

[0011] The third quality inspection column is horizontally and vertically slidably installed on the conveying track along the width direction of the conveying track, and a probe is installed on the third quality inspection column;

[0012] The third drive assembly is mounted on the frame and is used to drive the third quality inspection column to move. The probe extends into the annular groove of the inner ring of the bearing race under the action of the third drive assembly.

[0013] By adopting the above technical solution, after the bearing rings are processed, they enter the conveying track. The bearing rings roll within the conveying track, first passing through the inspection holes on the first inspection plate. The first inspection plate inspects the chamfer on the outer ring of the bearing ring. Bearing rings with chamfers meeting the standard requirements smoothly pass through the first inspection plate and move to the second inspection column. The second drive cylinder starts, driving the second inspection column to move and insert into the inner ring of the bearing ring to inspect its diameter. After the second inspection column inserts into a bearing ring with an inner ring diameter that meets the standard, it retracts, allowing the bearing ring to continue moving to the third inspection column. Then, the third drive cylinder... The starting component activates the third inspection column, which first extends into the inner ring of the bearing race. Then, it drives the third inspection column downward, allowing the probe to enter the annular groove of the bearing inner ring to detect the groove depth. For bearing races with annular groove depths that meet the standard, the probe automatically returns to its original position after reaching the target depth. Finally, the qualified bearing races are exported and collected via the conveyor track, thus completing the inspection of the bearing races. The inspection of the inner and outer rings and annular grooves of the bearing races is combined into a single conveyor track for centralized processing, greatly saving work space and streamlining the entire inspection process, thereby improving inspection efficiency.

[0014] Optionally, the third driving component includes:

[0015] The third drive board is vertically slidably mounted on the frame;

[0016] The third driving cylinder is mounted on the third driving plate and connected to the third quality inspection column;

[0017] The third drive screw is rotatably mounted on the frame and is in a vertical position. The third drive screw is threadedly connected to the third drive plate.

[0018] The third drive motor is mounted on the frame and its output shaft is connected to the third drive screw.

[0019] By adopting the above technical solution, the third drive cylinder starts to drive the third inspection column to extend into the inner ring of the bearing race. Then, the third drive motor starts to drive the third drive screw to rotate. The rotation of the third drive screw drives the third drive plate to move. The movement of the third drive plate drives the third drive cylinder to move vertically. The vertical movement of the third drive cylinder drives the probe to enter the inner ring groove of the bearing race for detection. Thus, the detection of the bearing race by the probe is realized by controlling the third drive cylinder and the third drive motor.

[0020] Optionally, a second positioning post and a third positioning post are horizontally slidable along the width direction on the conveying track. The second positioning post is located above the second quality inspection post, and the third positioning post is located above the third quality inspection post. A second moving cylinder and a third moving cylinder are provided on the frame for driving the second positioning post and the third positioning post to move respectively.

[0021] By adopting the above technical solution, after the bearing ring moves past the first inspection plate on the conveying track, the second moving cylinder is activated, driving the second positioning column to extend into the conveying track. The bearing ring stops after contacting the second positioning column, thus facilitating the second inspection column to inspect the inner ring of the bearing ring. After the second inspection column completes its inspection, the second moving cylinder drives the second positioning column to retract from the conveying track. At the same time, the third moving cylinder is activated, driving the third positioning column to enter the conveying track. The bearing ring stops after contacting the third positioning column, thus facilitating the third inspection column to inspect the bearing ring. After the inspection is completed, the third moving cylinder drives the third positioning column to retract from the conveying track, and the bearing ring can be exported.

[0022] Optionally, an air blowing pipe is provided on the conveying track. The air blowing pipe is located between the second quality inspection column and the first quality inspection plate. The air outlet of the air blowing pipe faces the direction of the second quality inspection column. The air blowing pipe is connected to an air source. The air blowing pipe is used to blow the bearing ring to roll from the position of the second quality inspection column to the position of the third quality inspection column within the conveying track.

[0023] By adopting the above technical solution, an air blowing pipe with its opening facing the third quality inspection column is fixed on the conveying track. After the second quality inspection column completes the quality inspection of the bearing ring and the second positioning column retracts, the air blowing pipe blows air onto the bearing ring, which drives the bearing ring to move towards the third positioning column. This reduces the probability that the bearing ring will remain on one side of the second positioning column after the inspection is completed at the second positioning column, ensuring the smooth progress of the inspection work. In addition, the air blowing pipe can effectively remove impurities on the conveying track, ensuring that the bearing ring can roll smoothly within the conveying track.

[0024] Optionally, a first pressure sensor is provided on the side wall of the first inspection plate away from the second inspection column, a second pressure sensor is provided on the end of the second inspection column away from the second drive cylinder, a third pressure sensor is provided on the probe, and a first electric door, a second electric door, and a third electric door are respectively opened along the length direction on the inner bottom wall of the conveying track. The first electric door is located below the first inspection plate and is electrically connected to the first pressure sensor, the second electric door is located below the second inspection column and is electrically connected to the second pressure sensor, and the third electric door is located below the third inspection column and is electrically connected to the third pressure sensor.

[0025] By adopting the above technical solution, when the chamfer of the outer ring of the bearing race does not meet the standard, the bearing race contacts the first inspection plate. The first pressure sensor on the first inspection plate transmits a signal to the first electric gate, which opens and causes the non-compliant bearing race to fall off the conveying track. When the inner ring diameter of the bearing race is smaller than the standard value, the second inspection column contacts the bearing race. The second pressure sensor transmits an electrical signal to the second electric gate after receiving pressure, which opens and causes the bearing race to fall off. When the inner ring groove depth of the bearing race does not meet the standard requirements, the probe contacts the bottom wall of the groove during its movement. The third pressure sensor transmits an electrical signal to the third electric gate after receiving pressure, which opens and discharges the non-compliant bearing race from the conveying track, thus completing the screening of the bearing race.

[0026] Optionally, the frame is provided with a collection assembly for collecting bearing rings that fall onto the conveyor track, the collection assembly comprising:

[0027] A collection box is mounted on a frame located below the conveyor track, and the top opening of the collection box is open.

[0028] Three guide plates are set on the conveying track and located below the first electric door, the second electric door, and the third electric door, respectively. The guide plates are used to guide the bearing rings that fall off the conveying track into the collection box.

[0029] By adopting the above technical solution, non-standard bearing rings will come into contact with the guide plate after falling off the conveyor track. Under the guidance of the guide plate, they will move into the collection box for unified collection, thus completing the recycling of non-conforming bearing rings. By setting up the guide plate, the probability of bearing rings being damaged and unusable is reduced.

[0030] Optionally, the conveying track is provided with an adjustment component for adjusting the height of the first quality inspection plate, the adjustment component including:

[0031] An adjusting screw, which is threadedly connected to the conveying track and is in a vertical position;

[0032] An adjusting block is vertically slidably mounted on an adjusting screw, and the first quality inspection plate is mounted on the adjusting block;

[0033] An adjusting nut is threaded onto an adjusting screw and abuts against the lower surface of an adjusting block.

[0034] A fastening nut is threaded onto the height adjustment screw and abuts against the upper surface of the adjustment block.

[0035] By adopting the above technical solution, the height of the adjusting block can be adjusted by loosening the fastening nut and disengaging it from the adjusting screw, and by rotating the height adjusting nut. The height of the first quality inspection plate can be adjusted by moving the adjusting block. After the adjustment is completed, the fastening nut is screwed into the adjusting screw and pressed against the adjusting block, thereby realizing the adjustment of the height of the first quality inspection plate and expanding the adaptability of the first quality inspection plate to bearing rings of different sizes.

[0036] Optionally, the first quality inspection plate is detachably connected to the adjusting block via a connecting assembly, the connecting assembly comprising:

[0037] A connecting screw is provided, and a first connecting hole is provided on the adjusting block along the length of the conveying track. A second connecting hole is provided on the first quality inspection plate. The connecting screw passes horizontally through the first connecting hole and the second connecting hole.

[0038] A connecting nut is threaded onto a connecting screw and abuts against the side wall of the first quality inspection plate.

[0039] By adopting the above technical solution, when the first inspection plate is damaged by the bearing ring during long-term operation or needs to be replaced due to the need to change the shape of the inspection hole, the first inspection plate can be removed and replaced by turning the connecting nut away from the connecting screw. The replaced first inspection plate is then moved and fitted onto the connecting screw, and the connecting nut is turned to connect with the connecting screw and press against the first inspection plate, thus completing the replacement of the first inspection plate.

[0040] Optionally, the connecting assembly is provided in two sets. The adjusting block has two first connecting holes, which are distributed along the width direction of the conveying track and located at the same height. The first quality inspection plate has two second connecting holes at the corresponding positions of the two first connecting holes on the adjusting block. Connecting screws are inserted into both the two first connecting holes and the two second connecting holes.

[0041] By adopting the above technical solution, two parallel connecting screws are installed on the first quality inspection plate, thereby improving the stability of the first quality inspection plate after installation and preventing the first quality inspection plate from deflecting at an angle during installation, thus improving the installation accuracy and strength of the first quality inspection plate.

[0042] Optionally, anti-collision sleeves are fitted on both the second and third positioning posts.

[0043] By adopting the above technical solution, anti-collision sleeves are fitted on the second and third positioning posts, so that when the bearing ring moves and comes into contact with the second and third positioning posts, the anti-collision sleeves buffer the impact of the bearing ring, reducing the probability of damage to the bearing ring due to rigid collision between the second and third positioning posts and the bearing ring.

[0044] In summary, this application includes at least one of the following beneficial technical effects:

[0045] 1. The first inspection plate checks the chamfer on the outer ring of the bearing race. Bearing races with chamfers meeting the standard requirements pass smoothly through the first inspection plate and move to the second inspection post. The second drive cylinder starts, moving the second inspection post and inserting it into the inner ring of the bearing race to check its diameter. Once the second inspection post is inserted into a bearing race with a standard inner ring diameter, it retracts, allowing the bearing race to continue moving to the third inspection post. Then, the third drive assembly starts, causing the third inspection post to first extend into the inner ring of the bearing race, and then... The third quality inspection column moves downward, allowing the probe to enter the annular groove of the inner ring of the bearing to detect the depth of the groove. For bearing rings with annular groove depth that meets the standard, the probe automatically returns to its original position after reaching the target depth. Finally, the qualified bearing rings are exported and collected through the conveyor track, thus completing the inspection of the bearing rings. The inspection of the inner and outer rings and annular grooves of the bearing rings is combined into a single conveyor track for centralized processing, which greatly saves work space and shortens the entire inspection process, improving the efficiency of the inspection work.

[0046] 2. The third drive cylinder is started to drive the third inspection column to extend into the inner ring of the bearing race. Then the third drive motor is started to drive the third drive screw to rotate. The rotation of the third drive screw drives the third drive plate to move. The movement of the third drive plate drives the third drive cylinder to move vertically. The vertical movement of the third drive cylinder drives the probe to enter the inner ring groove of the bearing race for detection. Thus, the detection of the bearing race by the probe is realized by controlling the third drive cylinder and the third drive motor.

[0047] 3. By installing anti-collision sleeves on the second and third positioning posts, the anti-collision sleeves buffer the impact on the bearing rings when they move and come into contact with the second and third positioning posts, thereby reducing the probability of damage to the bearing rings due to rigid collisions between the second and third positioning posts and the bearing rings.

The two connecting nuts 42 of the two sets of connecting assemblies 4 are threaded onto the two connecting screws 41 respectively and abut against the side wall of the first inspection plate 21 away from the adjusting block 32.

[0057] Reference Figure 1 and Figure 2 A second inspection column 22 is horizontally slidably installed on the conveyor track 11 along its width direction. The diameter of the second inspection column 22 is the same as the diameter of the inner ring of the bearing race. A second drive cylinder 23 is fixedly connected to the frame 1, and its piston rod is fixedly connected to the end of the second inspection column 22 away from the conveyor track 11.

A second moving cylinder 14 is fixedly connected to the frame 1, and the piston rod of the second moving cylinder 14 is connected to the second positioning column 13.

[0058] Reference Figure 1 and Figure 2 After the bearing ring passes through the inspection hole 12 on the first inspection plate 21, it moves to the position of the second inspection column 22. At this time, the second moving cylinder 14 is started to drive the second positioning column 13 to extend into the conveying track 11. The bearing ring moves to the point of contact with the second positioning column 13 and then stops. Then the second driving cylinder 23 is started to drive the second inspection column 22 to extend into the inner ring of the bearing to detect the diameter of the inner ring of the bearing.

Anti-collision sleeves are fitted on the side walls of both the third positioning column 17 and the second positioning column 13.

[0062] Reference Figure 1 and Figure 2 The second drive cylinder 23 drives the second inspection column 22 to retract to its original position after successfully extending into the inner ring of the bearing race. The second moving cylinder 14 is activated, driving the second positioning column 13 to retract to its original position. The air blowing pipe 15 blows air onto the bearing race, driving it to roll towards the third inspection column 24. The third moving cylinder 18 is activated, driving the third positioning column 17 to extend into the conveying track 11 and stop the bearing race. The third drive cylinder 27 is activated, driving the third inspection column 24 to extend into the inner ring of the bearing race. Then, the third drive motor 29 is activated, driving the third drive screw 28 to rotate. The rotation of the third drive screw 28 drives the third drive plate 26 to move downward. The downward movement of the third drive plate 26 drives the probe 16 to move downward into the inner ring groove of the bearing race to detect the depth of the inner ring groove.

[0063] Reference Figure 1 and Figure 2Pressure sensors are installed on the first inspection plate 21, the second inspection column 22, and the probe 16. Three material discharge holes are formed along the length of the lower surface of the conveyor track 11. These three holes are located below the first inspection plate 21, the second inspection column 22, and the third inspection column 24, respectively. A first electric door 51, a second electric door 52, and a third electric door 53 are rotatably mounted on the lower surface of the conveyor track 11.

[0064] Reference Figure 1 and Figure 2 When the outer ring chamfer of the bearing race does not meet the standard, the bearing race rolls on the conveying track 11 and comes into contact with the first inspection plate 21. The pressure sensor on the first inspection plate 21, under pressure, transmits an electrical signal to the first electric gate 51, which opens to discharge the non-compliant bearing race from the conveying track 11. When the inner ring diameter of the bearing race does not meet the standard, the second inspection column 22 moves and comes into contact with the side wall of the bearing race. The pressure sensor on the second inspection column 22, under pressure, transmits an electrical signal to the second electric gate 52, which opens to discharge the bearing race from the conveying track 11. When the inner ring groove depth of the bearing race does not meet the standard, the probe 16 moves and comes into contact with the bottom surface of the inner ring groove. The pressure sensor on the probe 16, under pressure, transmits an electrical signal to the third electric gate 53, which opens to discharge the bearing race from the conveying track 11.

The upper opening of the collection box 61 is open. The three guide plates 62 are all fixedly connected to the lower surface of the conveyor track 11 and are inclined. The three guide plates 62 are located on one side of the three drop holes and are used to receive the bearing rings that fall out of the drop holes.

[0066] The working principle of this application embodiment is as follows:

[0067] After the bearing rings enter the conveying track 11, they are first inspected by the first inspection plate 21. Bearing rings that do not meet the standards will collide with the first inspection plate 21 and then fall into the collection box 61 through the first electric gate 51. Qualified bearing rings continue to roll after passing through the inspection hole 12 until they contact the second positioning post 13. Then, the second drive cylinder 23 is activated, which drives the second inspection post 22 to extend into the bearing ring. Bearing rings that do not meet the standards will collide with the second inspection post 22 and then fall into the collection box 61 through the second electric gate 52. Qualified bearing rings roll until they contact the third positioning post 17. Then, the third inspection post 24 drives the probe 16 to detect the depth of the annular groove of the bearing ring. Qualified bearing rings fall into the collection box 61, while qualified bearing rings are exported through the conveying track 11.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
