Description

Technical Field

[0001] The invention relates to the technical field of bearing seat assembly torque testing, and in particular to a vertical bearing seat assembly torque testing device and a testing method. Background Art

[0002] Vertical bearing seats are widely used in mechanical equipment, especially in industrial transmission systems and automation equipment. Their main function is to support and position the rotating shaft, thereby ensuring the smooth operation and efficient transmission of the equipment. In the manufacturing and assembly process of vertical bearing seats, it is crucial to ensure that each component is tightened with the correct torque, which not only affects the performance and life of the equipment, but also its safety and reliability. Therefore, an assembly torque test device is required. The existing test device still has some shortcomings.

[0003] The invention patent with the publication number of CN111562045A discloses a bearing and bearing seat assembly torque test device and test method, including a placement table, a fixing part, a sensor and a reading table, wherein the fixing part is arranged on the top of the placement table, and a receiving space for placing the base of the bearing seat is arranged between the fixing part and the placement table; the sensor is arranged at the bottom of the placement table, and the reading table is electrically connected to the sensor; the method applies pressure to the bearing seat through the bearing to drive the placement table to rotate until it contacts the sensor, so that the pressure value is tested by the sensor and displayed by the reading table, and the pressure when the bearing is assembled to the bearing seat is transmitted through the placement table, and the pressure is measured by the sensor and displayed through the reading table, so that the tester can calculate the assembly torque according to the pressure value, thereby achieving the effect of intuitively recording the torque. However, when in use, it is not possible to stop increasing the pressure and continue to transmit torque after the pressure of the outer race of the bearing reaches a certain level for assembly torque test. Conventional test structures usually require multiple driving devices to realize the functions of pressing and transmitting torque, and cannot realize the torque test function through a single driving device. Summary of the invention

A hydraulic rod is installed in the middle of the first connecting plate, and a third connecting plate is fixedly connected to the hydraulic rod, and a third guide rod is fixedly connected to all four sides of the third connecting plate.

[0007] As a preferred solution of the present invention, the second bracket, the third bracket and the first guide rod are symmetrically distributed on both sides of the first bracket, and the support plate and the first bracket are parallel to each other.

[0008] As a preferred solution of the present invention, the connecting assembly includes a first connecting shaft fixedly connected to the motor output shaft, a movable groove is provided in the first connecting shaft, a first spring is fixedly connected to the inner wall of the movable groove, a connecting block is fixedly connected to the first spring, and the screw rod is provided with a groove for docking with the connecting block.

[0009] As a preferred solution of the present invention, the connecting block is shaped like a truncated cone, the diameter of the connecting block increases from the side close to the central axis of the screw to the side away from the central axis of the screw, and the outer wall of the connecting block fits with the inner wall of the groove.

[0010] As a preferred solution of the present invention, the outer wall of the first connecting shell and the inner wall of the second connecting shell are in contact with each other, and an inner groove for the first connecting shell to slide is provided in the second connecting shell.

[0011] As a preferred solution of the present invention, the material of the first connecting shell is rubber material, the pushing assembly includes a second electric push rod fixedly connected to the second bracket, a rubber block is fixedly connected to the second electric push rod, a ball is rotatably mounted on the rubber block, and the ball is suitable for pressing the first connecting shell and the second connecting shell when the second electric push rod is extended.

[0012] As a preferred solution of the present invention, the connection assembly includes a second spring fixedly connected to the second connection shell, a clamping block is fixedly connected to the second spring, a clamping groove is opened in the first connection shell, and the inner wall of the clamping groove and the outer wall of the clamping block are in contact with each other.

[0013] As a preferred solution of the present invention, the block is a spherical structure, the center of the block is located inside the second connecting shell, and the blocks are evenly spaced around the inner wall of the second connecting shell.

[0014] As a preferred solution of the present invention, the central axes of the key tube and the first connecting plate are collinear, the first connecting plate, the first connecting rod and the second connecting plate are fixedly connected to form an integral structure, and the third guide rod runs through the interior of the second connecting plate.

[0015] A method for testing the assembly torque of a vertical bearing seat comprises the following steps:

[0016] S1: The screw is driven to rotate by a motor. When the screw rotates, it drives the first connection shell to move toward the direction close to the bearing seat body, and the second connection shell and the first connection shell are driven to move synchronously through the connection assembly, so that the first connection plate, the first connection rod and the second connection plate are close to the bearing seat body, so that the second connection rod abuts against the outer race of the bearing in the bearing seat body;

[0017] S2: Under the guidance of the connecting tube and the second guide rod, the rotation of the screw can make the first connecting shell and the second connecting shell slide straightly along the length direction of the screw. At the same time, the rotation of the screw will also drive the connecting rod to rotate synchronously, and the key block will drive the key tube and the first connecting plate to rotate. When the first connecting plate rotates, it will drive the first connecting rod and the second connecting plate to rotate. Since the second connecting rod on the second connecting plate abuts against the outer race of the bearing in the bearing seat body, observe whether the outer race can be rotated, thereby detecting the assembly torque of the bearing seat;

[0018] S3: After the second connecting rod abuts against the outer race of the bearing in the bearing seat body, during the assembly torque test, it is necessary to continuously drive the first connecting plate to rotate, so the first connecting shell will continue to move. When the second connecting shell cannot move further, the connecting assembly no longer maintains the engagement state of the first connecting shell and the second connecting shell, and the first connecting shell will slide in the inner groove in the second connecting shell. The connecting rod still drives the key cylinder to rotate through the key block, and the first connecting plate rotates on the second connecting shell through the connecting ring. The connecting rod slides in the key cylinder, so that the device stops increasing the pressure on the outer race of the bearing after the pressure reaches a certain level and continues to transmit torque.

[0019] S4: When the abutment effect during the assembly torque test needs to be adjusted, the third connecting plate can be moved toward the bearing seat body by extending the hydraulic rod until the third guide rod and the second connecting rod are in abutment with the outer race of the bearing in the bearing seat body, thereby increasing the contact surface during the test.

[0020] The working principle and beneficial effects of the present invention are:

[0021] 1. Through the provided connecting assembly, connecting rod, key block and key cylinder, when the screw rotates, it will drive the first connecting shell to slide, and the connecting assembly makes the second connecting shell move in the direction close to the bearing. At the same time, the rotation of the screw will also drive the connecting rod to rotate synchronously, and the key cylinder and the first connecting plate are driven to rotate through the key block, so that the second connecting rod on the device can generate torque after abutting the outer race of the bearing, and observe whether the outer race of the bearing can rotate in the bearing seat, so as to detect the assembly torque of the bearing seat. The device can realize the functions of abutting the bearing and providing the test torque through a single driving device, which solves the problem that the existing test device cannot test the assembly torque of the bearing seat through a single driving device, and enhances the convenience of the device when used.

[0022] 2. Through the first connecting shell and the second connecting shell on the device, when the second connecting shell continues to move until the second connecting rod abuts against the outer race of the bearing, the second connecting shell cannot move further, while the first connecting shell can still continue to move in the inner groove of the second connecting shell. The block of the spherical structure on the connecting assembly is intermittently pushed, and the key block on the connecting rod continuously drives the key cylinder and the first connecting plate to rotate, so that the device can continue to provide torque while maintaining pressure on the outer race of the bearing, which solves the problem that the existing test device cannot stop increasing the pressure and continue to transmit torque to perform assembly torque test after the pressure on the outer race of the bearing reaches a certain level. The device has the advantage of greater adaptability.

[0023] 3. By setting up a push assembly and extending the second electric push rod on the push assembly, the ball on the rubber block presses the first connecting shell made of rubber material through the second electric push rod, thereby increasing the pressure between the first connecting shell and the second connecting shell, thereby increasing the screw torque required for the first connecting shell and the second connecting shell to disengage from the engaged state, thereby enabling the device to enhance the pressing effect on the outer race of the bearing, thereby changing the maximum value of the pressure on the outer race of the bearing during the test, so that the device can adapt to different bearing seats for use.

DETAILED DESCRIPTION

[0035] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figure 1-Figure 9As shown, this embodiment proposes a vertical bearing seat assembly torque test device, including a first bracket 1, a second bracket 2 and a third bracket 3 are fixedly connected to the first bracket 1, a first guide rod 5 is fixedly connected to the first bracket 1, a support plate 6 is slidably installed on the outer side of the first guide rod 5, a bearing seat body 7 is placed on the support plate 6, a first electric push rod 8 is installed between the first bracket 1 and the support plate 6, a motor 4 is installed on the third bracket 3, a connecting component 9 is fixedly connected to the output shaft of the motor 4, a screw 10 is connected to the connecting component 9, a first connecting shell 12 is threadedly connected to the outer side of the screw 10, a second connecting shell 13 is installed on the outer side of the first connecting shell 12, a connecting tube 14 is fixedly connected to the second connecting shell 13, a second guide rod 15 is slidably installed in the connecting tube 14, the second guide rod 15 and the first bracket 1 are fixedly connected, and the first connecting shell A connecting assembly 16 is provided between 12 and the second connecting shell 13, and pushing assemblies 11 are provided on the upper and lower sides of the second connecting shell 13. A connecting ring 17 is installed on the second connecting shell 13, and a first connecting plate 21 is rotatably installed on the outer side of the connecting ring 17. First connecting rods 22 are welded around the first connecting plate 21, and a second connecting plate 23 is welded on the first connecting rod 22. A hydraulic rod 24 is installed in the middle of the first connecting plate 21, and a third connecting plate 25 is fixedly connected to the hydraulic rod 24. The third connecting plate 25 is fixedly connected to the third guide rods 26 around the third connecting plate 25, and the second connecting rods 27 are fixedly provided around the second connecting plate 23. A connecting rod 18 is fixedly connected to the screw rod 10, and a key block 19 is fixedly provided around the connecting rod 18. A key cylinder 20 is slidably installed on the outer side of the key block 19, and the key cylinder 20 and the first connecting plate 21 are fixedly connected. When the motor 4 drives the screw 10 to rotate, it will drive the first connection shell 12 and the second connection shell 13 to slide on the second guide rod 15, so that the second connection rod 27 on the device is pressed against the outer race of the bearing, so as to perform the assembly torque test later. After the second connection rod 27 is pressed against the outer race of the bearing, the screw 10 continues to rotate, and the connecting component 16 no longer maintains the engagement state of the first connection shell 12 and the second connection shell 13, so that the device can continue to push the first connection shell 12 to move after pushing the first connection plate 21 to the limit position, and keep the second connection shell 13 stationary. The continuous rotation of the screw 10 will also drive the key cylinder 20 to rotate through the key block 19 on the connecting rod 18, and the key cylinder 20 drives the first connection plate 21 to rotate, so that the device can continue to apply torque to perform the assembly torque test while maintaining the pressing effect on the bearing seat. When the rotation resistance is too large, the connecting component 9 on the device can play an overload protection function.

[0038] Example 2

[0039] like Figure 1-Figure 9 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a vertical bearing seat assembly torque testing device.

[0040] In this embodiment, the second bracket 2, the third bracket 3 and the first guide rod 5 are symmetrically distributed on both sides of the first bracket 1, so that the left and right sides of the bearing seat can be stably pressed, the support plate 6 and the first bracket 1 are parallel to each other, and the support plate 6 can move up and down on the first bracket 1, thereby supporting the bearing seat and adjusting the height of the bearing seat at the same time.

[0041] In this embodiment, the connecting assembly 9 includes a first connecting shaft 901 fixedly connected to the output shaft of the motor 4, a movable groove 902 is provided in the first connecting shaft 901, a first spring 903 is fixedly connected to the inner wall of the movable groove 902, a connecting block 904 is fixedly connected to the first spring 903, and a groove 905 for docking with the connecting block 904 is provided on the screw 10. The device can detect whether the bearing in the bearing seat is stably assembled by pressing against and rotating the outer race of the bearing in the bearing seat to observe whether the outer race of the bearing rotates in the bearing seat. When the rotation resistance of the screw 10 used to apply torque is too large, such as Figure 4 As shown, the connecting block 904 is abutted by the inner wall of the groove 905, so that the first connecting shaft 901 slides on the outer side of the screw rod 10, thereby realizing the overload protection function.

[0042] In this embodiment, the connecting block 904 is in the shape of a truncated cone, and the diameter of the connecting block 904 increases gradually from the side close to the central axis of the screw 10 to the side away from the central axis of the screw 10. The outer wall of the connecting block 904 fits with the inner wall of the groove 905. When the side surface of the connecting block 904 with a truncated cone structure is compressed, it will slide toward the side away from the central axis of the screw 10, thereby avoiding damage to the screw 10 when the rotational resistance of the device is too large, thereby ensuring the safety of the device when in use.

[0043] In this embodiment, the outer wall of the first connecting shell 12 and the inner wall of the second connecting shell 13 are in contact with each other. An inner groove 28 is provided in the second connecting shell 13 for the first connecting shell 12 to slide. When the second connecting shell 13 cannot move further, the inner groove 28 allows the first connecting shell 12 to slide.

[0044] In this embodiment, the material of the first connecting shell 12 is rubber material, and the pushing assembly 11 includes a second electric push rod 1101 fixedly connected to the second bracket 2, and a rubber block 1102 is fixedly connected to the second electric push rod 1101, and a ball 1103 is rotatably installed on the rubber block 1102. The ball 1103 is suitable for pressing the first connecting shell 12 and the second connecting shell 13 when the second electric push rod 1101 is extended. By extending the second electric push rod 1101, the rubber block 1102 is abutted against the second connecting shell 13, thereby increasing the pressing effect of the first connecting shell 12 and the second connecting shell 13. The higher the degree of pressing of the first connecting shell 12 and the second connecting shell 13, the greater the thrust required for the first connecting shell 12 and the second connecting shell 13 to disengage, thereby changing the test strength of the device during the subsequent bearing seat assembly torque test.

[0045] In this embodiment, the connecting component 16 includes a second spring 1602 fixedly connected to the second connecting shell 13, and a block 1601 is fixedly connected to the second spring 1602. A slot 1603 is opened in the first connecting shell 12, and the inner wall of the slot 1603 and the outer wall of the block 1601 fit each other. The second spring 1602 can make the block 1601 and the slot 1603 stably docked, so that the first connecting shell 12 and the second connecting shell 13 remain in a locked state, and when the second connecting shell 13 cannot move further, the inner wall of the slot 1603 on the first connecting shell 12 can abut the block 1601, so that the second spring 1602 on the block 1601 is compressed until the block 1601 is completely retracted into the second connecting shell 13. At this time, the first connecting shell 12 and the second connecting shell 13 are out of the locked state, so that torque can be continuously applied after the bearing seat is tightened to perform assembly torque test.

[0046] In this embodiment, the card block 1601 is a spherical structure. When the spherical surface of the card block 1601 is compressed, the card block 1601 will be automatically retracted. The center of the card block 1601 is located inside the second connecting shell 13. The card blocks 1601 are evenly spaced around the inner wall of the second connecting shell 13. The evenly spaced card blocks 1601 ensure the clamping effect between the two connecting shells, thereby enhancing the overall stability of the device.

[0047] In this embodiment, the central axes of the key cylinder 20 and the first connecting plate 21 are collinear, the first connecting plate 21, the first connecting rod 22 and the second connecting plate 23 are fixedly connected to form an integral structure, and the third guide rod 26 runs through the interior of the second connecting plate 23. The position of the third guide rod 26 can be adjusted to change the number of contact surfaces between the device and the bearing seat when performing an assembly torque test.

[0048] Specifically, the present invention is a vertical bearing seat assembly torque test device and test method, first, as Figure 1-Figure 3 and Figure 7-Figure 9As shown, the first bracket 1, the second bracket 2 and the third bracket 3 are used to support the device as a whole, the first guide rod 5 and the support plate 6 ensure that the bearing seat body 7 can be stably supported, and the first electric push rod 8 is used to adjust the support height of the bearing seat body 7. The motor 4 drives the screw rod 10 to rotate, and the screw rod 10 drives the first connecting shell 12 to move toward the direction close to the bearing seat body 7 when rotating, and the inner wall of the card slot 1603 on the connecting component 16 is pressed against the outer wall of the card block 1601, thereby driving the second connecting shell 13 and the first connecting shell 12 to move synchronously, so that the first connecting plate 21, the first connecting rod 22 and the second connecting plate 23 are close to the bearing seat body 7, so that the second connecting rod 27 abuts against the outer race of the inner bearing of the bearing seat body 7. Under the guidance of the connecting tube 14 and the second guide rod 15, the rotation of the screw 10 can make the first connecting shell 12 and the second connecting shell 13 slide straight along the length direction of the screw 10. At the same time, the rotation of the screw 10 will also drive the connecting rod 18 to rotate synchronously, and drive the key tube 20 and the first connecting plate 21 to rotate through the key block 19. When the first connecting plate 21 rotates, it will drive the first connecting rod 22 and the second connecting plate 23 to rotate. Since the second connecting rod 27 on the second connecting plate 23 abuts against the outer race of the bearing in the bearing seat body 7, observe whether the outer race can be rotated, thereby detecting the assembly torque of the bearing seat. When the outer race of the bearing in the bearing seat cannot rotate, the rotation resistance of the screw 10 is too large, such as Figure 4 As shown, the connecting block 904 is supported by the inner wall of the groove 905, so that the first connecting shaft 901 slides on the outside of the screw 10. When the outer race of the bearing rotates, the screw 10 can continue to rotate until the first connecting shell 12 can no longer move in the second connecting shell 13. The screw 10 stops rotating due to excessive rotation resistance, thereby judging the assembly torque of the bearing seat.

[0049] like Figure 1-Figure 6 , Figure 8 and Fig. 9As shown, after the second connecting rod 27 abuts against the outer race of the bearing in the bearing seat body 7, during the assembly torque test, it is necessary to continuously drive the first connecting plate 21 to rotate, so the first connecting shell 12 will continue to move. When the second connecting shell 13 cannot move further, the connecting assembly 16 no longer maintains the engagement state between the first connecting shell 12 and the second connecting shell 13, and the inner wall of the card slot 1603 on the first connecting shell 12 abuts against the card block 1601, so that the second spring 1602 on the card block 1601 is compressed until the card block 16 01 is completely retracted into the second connecting shell 13. At this time, the first connecting shell 12 and the second connecting shell 13 are out of engagement. The first connecting shell 12 will slide in the inner groove 28 in the second connecting shell 13. At this time, the screw 10 continues to rotate, and the connecting rod 18 still drives the key cylinder 20 to rotate through the key block 19. The first connecting plate 21 rotates on the second connecting shell 13 through the connecting ring 17, and the connecting rod 18 slides in the key cylinder 20, so that the device stops increasing the pressure on the outer race of the bearing after the pressure reaches a certain level and continues to transmit torque. When it is necessary to adjust the abutment effect during the assembly torque test, the third connecting plate 25 can be moved toward the direction of the bearing seat body 7 by extending the hydraulic rod 24 until the third guide rod 26 and the second connecting rod 27 are both in abutment with the outer race of the bearing in the bearing seat body 7. At this time, the contact surface during the test can be increased.

[0050] like Figure 1 , Figure 2 and Figure 5 As shown, the device can change the test strength by extending the second electric push rod 1101 so that the rubber block 1102 abuts against the second connecting shell 13, thereby increasing the clamping effect of the first connecting shell 12 and the second connecting shell 13. The higher the degree of clamping of the first connecting shell 12 and the second connecting shell 13, the greater the thrust required for the first connecting shell 12 and the second connecting shell 13 to disengage, thereby changing the test strength of the device when performing subsequent bearing seat assembly torque test. The ball 1103 allows the second spring 1602 in the second connecting shell 13 to maintain a clamped state without affecting the forward and backward movement of the second connecting shell 13.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

10. A method for testing the assembly torque of a vertical bearing seat, using the device for testing the assembly torque of a vertical bearing seat according to claim 1, characterized in that: The steps include: S1: The screw rod (10) is driven to rotate by the motor (4). When the screw rod (10) rotates, it drives the first connecting shell (12) to move in a direction close to the bearing seat body (7). The second connecting shell (13) and the first connecting shell (12) are driven to move synchronously through the connecting assembly (16), so that the first connecting plate (21), the first connecting rod (22) and the second connecting plate (23) are close to the bearing seat body (7), so that the second connecting rod (27) abuts against the outer race of the bearing inside the bearing seat body (7); S2: Under the guidance of the connecting tube (14) and the second guide rod (15), the screw rod (10) rotates to make the first connecting shell (12) and the second connecting shell (13) slide straight along the length direction of the screw rod (10). At the same time, the screw rod (10) rotates to drive the connecting rod (18) to rotate synchronously, and drives the key tube (20) and the first connecting plate (21) to rotate through the key block (19). When the first connecting plate (21) rotates, it drives the first connecting rod (22) and the second connecting plate (23) to rotate. Since the second connecting rod (27) on the second connecting plate (23) abuts against the outer race of the bearing inside the bearing seat body (7), it is observed whether the outer race can be rotated, thereby detecting the assembly torque of the bearing seat; S3: When the second connecting rod (27) abuts against the outer race of the bearing in the bearing seat body (7), during the assembly torque test, it is necessary to continuously drive the first connecting plate (21) to rotate, so the first connecting shell (12) will continue to move. When the second connecting shell (13) cannot move further, the connecting assembly (16) no longer maintains the engagement state between the first connecting shell (12) and the second connecting shell (13), and the first connecting shell (12) will slide in the inner groove (28) in the second connecting shell (13). The connecting rod (18) still drives the key cylinder (20) to rotate through the key block (19). The first connecting plate (21) rotates on the second connecting shell (13) through the connecting ring (17), and the connecting rod (18) slides in the key cylinder (20), so that the device stops increasing the pressure on the outer race of the bearing after the pressure reaches a certain level and continues to transmit torque; S4: When it is necessary to adjust the abutment effect during the assembly torque test, the third connecting plate (25) can be moved toward the bearing seat body (7) by extending the hydraulic rod (24) until the third guide rod (26) and the second connecting rod (27) are in abutment with the outer race of the bearing inside the bearing seat body (7), thereby increasing the contact surface during the test.
