Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection equipment, in particular to a detection equipment for detecting bearings. Background Art

[0002] During the production of rolling bearings, various parameters of the bearings need to be tested to determine whether the product is qualified. Among them, the ovality, outer diameter and taper of the outer and inner rings of the bearings are very important parameters. When measuring the ovality, outer diameter and taper of the outer and inner rings of the bearings, first measure the outer diameter and outer diameter variation of the outer and inner rings, and then calculate them through the inherent calculation formula. Therefore, when measuring the ovality, outer diameter and taper of the outer and inner rings of the bearings, it is actually measuring the outer diameter and outer diameter variation. Due to different processing techniques, the ovality, outer diameter and taper of the outer and inner rings of the bearings do not meet the requirements, so it is necessary to measure the ovality, outer diameter and taper of the outer and inner rings of the bearings to ensure the quality of the products.

[0003] At present, the outer diameter and outer diameter variation of the outer ring and inner ring of the bearing are all completed by offline random inspection, and the random inspection is mostly carried out through manual inspection, which has low inspection efficiency and cannot ensure the consistency of each measurement during inspection; moreover, in the process of random inspection, the outer diameter and outer diameter variation of all the outer rings and inner rings of the bearing cannot be inspected. Therefore, there are deficiencies in the measurement of the ovality, outer diameter and taper of the outer ring and inner ring of the bearing.

[0004] The Chinese patent with the authorization announcement number CN211717340U discloses a bearing parameter detection device, which realizes the online measurement of the outer diameter and outer diameter variation of the outer and inner rings of the bearing without affecting the measurement efficiency and measurement accuracy of the outer and inner rings of the bearing. It optimizes the processing technology of the bearing and eliminates the process steps of offline sampling inspection; ensures that the outer diameter and outer diameter variation of each bearing product can meet the processing requirements, and also ensures that the ovality, outer diameter and taper of the bearing product can meet the processing requirements, thereby improving the processing quality of the bearing;

[0005] Although this type of bearing parameter detection equipment can detect the outer diameter and outer diameter variation of the bearing, in actual use, the bearing fixing method is relatively simple. When detecting the outer diameter and outer diameter variation of the bearing, the bearing needs to rotate at high speed. If the bearing cannot be firmly fixed on the detection table, the bearing will rotate at high speed and leave the detection table during the detection process, which will cause damage to the bearing and even injure the detection personnel in serious cases.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 5 , the utility model provides a technical solution:

[0029] A detection device for detecting bearings, comprising a detection platform 1, support legs 2 are fixedly installed at the four corners of the lower end surface of the detection platform 1, a motor 3 is embedded and connected to the middle of the upper end surface of the detection platform 1, an output shaft is arranged at the upper end of the motor 3, a threaded rod 4 is fixedly installed on the upper end of the output shaft of the motor 3, a fixing mechanism is fixedly installed on the outer surface of the threaded rod 4, a detection mechanism is arranged on the outer side of the fixing mechanism, the fixing mechanism comprises a threaded sleeve 5 connected with a spiral transmission on the lower side of the outer surface of the threaded rod 4, a connecting rod 1 is rotatably connected to the outer surface of the threaded sleeve 5, a threaded sleeve 2 is connected with a spiral transmission on the upper side of the outer surface of the threaded rod 4, a connecting rod 2 is rotatably connected to the outer surface of the threaded sleeve 27, a connecting rod 2 is rotatably connected to the outer surface of the threaded sleeve 27, a top block 9 is arranged on the outer side of the threaded rod 4, and both the connecting rod 16 and the connecting rod 28 are rotatably connected to the top block 9. A top plate 10 is fixedly installed on the left end of the top block 9. The top block 9, the top plate 10, the connecting rod 1 6 and the connecting rod 2 8 are correspondingly arranged in three groups. The three groups of connecting rod 1 6 are rotatably connected to the threaded sleeve 1 5, and the three groups of connecting rod 2 8 are rotatably connected to the threaded sleeve 2 7.

[0030] By adopting the above technical scheme, in the actual use process, the bearing fixing method is relatively simple. When the outer diameter and the outer diameter change of the bearing are detected, the bearing needs to rotate at high speed. If the bearing cannot be firmly fixed on the detection platform 1, the bearing will rotate at high speed and separate from the detection platform 1 during the detection process, which will cause damage to the bearing, and even seriously injure the detection personnel. Therefore, the utility model sets a fixing mechanism, uses the output shaft of the motor 3 to drive the threaded rod 4 to rotate, and expands and fixes the inner ring of the bearing under the action of the threaded sleeve 5, the connecting rod 6, the threaded sleeve 2, the connecting rod 2 and the top block 9, providing a more stable fixing method, improving the safety of the equipment, and the fixing mechanism can fix bearings of different sizes, which is relatively improved. The practicability of the equipment is improved. Specifically: when the bearing body 12 needs to be inspected, the bearing body 12 is placed on the upper side of the fixing ring 11 and sleeved on the outer surface of the fixing mechanism, and then the motor 3 is started to make the output shaft of the motor 3 carry the threaded rod 4 to rotate, and the threaded sleeve 15 and the threaded sleeve 27 connected by the spiral transmission on the outer surface of the threaded rod 4 will move towards each other, the threaded sleeve 15 carries the connecting rod 16 to move, and the threaded sleeve 27 carries the connecting rod 28 to move. The connecting rod 16 and the connecting rod 28 are both rotatably connected to the top block 9 fixedly installed at the rear end of the top plate 10. Therefore, under the mutual cooperation of the connecting rod 16 and the connecting rod 28, the top block 9 is driven to be tightly attached to the inner wall of the bearing. The combination of the connecting rod 16, the connecting rod 28, the top block 9 and the top plate 10 is provided in three groups, and cooperates with each other to fix the bearing.

[0031] like Figure 2 and Figure 5As shown, the detection mechanism includes a fixing ring 11 fixedly installed on the upper end surface of the detection platform 1, and a toothed disc 13 is rotatably connected to the outer surface of the fixing ring 11. A platform 14 is arranged on the upper side of the toothed disc 13, and fixing columns 15 are fixedly installed between the four corners of the lower end surface of the platform 14 and the detection platform 1, and a bearing body 12 is arranged on the upper end of the fixing ring 11, and the bearing body 12 is sleeved on the outer surface of the fixing mechanism, and a motor 2 16 is fixedly installed on the right end of the platform 14, and an output shaft is arranged at the lower end of the motor 2 16, and a gear 17 is fixedly installed on the lower end of the output shaft of the motor 2 16, and the gear 17 is meshed with the toothed disc 13, and a transmission groove 18 is provided on the upper end surface of the toothed disc 13, and the transmission groove 18 is arranged in an arc shape, and a limiting groove 19 is provided on the upper end surface of the platform 14, and a slide rod 20 is slidably connected to the inside of the transmission groove 18, and the slide rod 20 extends to the inside of the limiting groove 19 and is engaged with the limiting groove 19. The groove 19 is slidably connected, and a support platform 21 is fixedly installed on the upper end of the slide bar 20. There are three groups of limit grooves 19, transmission grooves 18, slide bars 20 and support platforms 21, and they are arranged in a ring-shaped dispersed manner. One end of one group of support platforms 21 is rotatably connected to a driving wheel 22, a motor three 23 is arranged on the upper side of the support platform 21, and an output shaft is arranged at the lower end of the motor three 23. The output shaft of the motor three 23 is fixedly connected to the driving wheel 22, and a fixing member 24 is fixedly installed between the motor three 23 and the support platform 21. One end of the other two groups of support platforms 21 is fixedly installed with a sleeve 25, and a sliding column 26 is slidably connected to the right end of the sleeve 25. A support member 28 is fixedly installed on the right end of the sliding column 26, and a spring 27 is fixedly installed between the support member 28 and the support platform 21. The right end of the support member 28 is rotatably connected to a driven wheel 29, and a displacement sensor 30 is fixedly installed on the upper end surface of the support platform 21.

[0032] By adopting the above technical scheme, the outer diameter and outer diameter variation of the outer ring and inner ring of the bearing are currently completed by offline random inspection, and the random inspection is mostly carried out by manual inspection, the inspection efficiency is not high, and the measurement consistency cannot be ensured each time during the inspection; moreover, in the process of random inspection, the outer diameter and outer diameter variation of all the outer rings and inner rings of the bearing cannot be detected. Therefore, there are deficiencies in the measurement of the ovality, outer diameter and taper of the outer ring and inner ring of the bearing. Therefore, the utility model sets a detection mechanism, uses the motor 2 16 to drive the gear plate 13 to rotate, and under the action of the transmission groove 18 and the limit groove 19, the slide bar 20 pushes the support 21 to approach the bearing, and then pushes the displacement sensor 30 and the drive wheel 22 to fit tightly with the bearing body 12, and performs inspection, without manual inspection, which relatively improves the convenience of the equipment. Specifically: after the fixation is completed, by starting the motor 2 1 6, so that the output shaft of the motor 2 16 carries the gear 17 to rotate, the gear 17 meshes with the toothed disc 13 for transmission, and then drives the toothed disc 13 to rotate, the toothed disc 13 rotates through the transmission groove 18 opened on the upper end surface, so that the slide bar 20 inside the transmission groove 18 is displaced, and the slide bar 20 is synchronously slidably connected to the inside of the limit groove 19, the limit groove 19 limits the displacement direction of the slide bar 20, so that the slide bar 20 carries the support 21 to approach the bearing, wherein two groups of the support 21 are provided with displacement sensors 30, and one group of the support 21 is provided with a driving wheel 22, by starting the output shaft of the motor 3 23, the output shaft drives the driving wheel 22 to rotate, the driving wheel 22 is arranged close to the outer ring of the bearing, so that the bearing will be driven to rotate at high speed, when the bearing rotates at high speed, the outer diameter and the outer diameter change of the outer ring and the inner ring of the bearing can be measured online through the displacement sensor 30.

[0033] Working principle: when it is necessary to inspect the bearing body 12, place the bearing body 12 on the upper side of the fixing ring 11 and sleeve it on the outer surface of the fixing mechanism, then start the motor 3, so that the output shaft of the motor 3 carries the threaded rod 4 to rotate, and the threaded sleeve 15 and the threaded sleeve 27 connected by the spiral transmission on the outer surface of the threaded rod 4 will move towards each other, the threaded sleeve 15 carries the connecting rod 16 to move, and the threaded sleeve 27 carries the connecting rod 28 to move, and the connecting rod 16 and the connecting rod 28 are both rotatably connected to the top block 9 fixedly installed at the rear end of the top plate 10. Therefore, under the mutual cooperation of the connecting rod 16 and the connecting rod 28, the top block 9 is driven to be tightly attached to the inner wall of the bearing. There are three groups of the combination of the connecting rod 16, the connecting rod 28, the top block 9 and the top plate 10, and they cooperate with each other to fix the bearing. After the fixing is completed, by starting the motor 2 16, the output shaft of the motor 2 16 carries The gear 17 rotates, and the gear 17 meshes with the toothed disc 13 for transmission, thereby driving the toothed disc 13 to rotate. The toothed disc 13 rotates through the transmission groove 18 opened on the upper end surface, so that the slide bar 20 inside the transmission groove 18 is displaced, and the slide bar 20 is synchronously slidably connected to the inside of the limit groove 19. The limit groove 19 limits the displacement direction of the slide bar 20, so that the slide bar 20 carries the support 21 to approach the bearing, wherein two groups of support 21 are provided with displacement sensors 30, and one group of support 21 is provided with a driving wheel 22. By starting the output shaft of the motor three 23, the output shaft drives the driving wheel 22 to rotate. The driving wheel 22 is arranged close to the outer ring of the bearing, so that the bearing will be driven to rotate at high speed.
