[0002] As a core support component in the mechanical transmission system, the inner diameter dimension accuracy of the bearing housing directly determines the installation quality of the bearing and the operation stability of the equipment. If there are deviations in the inner diameter dimension, it will cause the bearing assembly to be too tight or too loose, and then lead to problems such as abnormal vibration, increased temperature rise, and accelerated wear. In severe cases, it may even cause the equipment to stop.

[0003] Therefore, in the quality inspection link before the production and assembly of the bearing housing, the accurate measurement of the inner diameter parameter is a key step to ensure the product qualification rate.

[0004] After retrieval, a Chinese patent with the publication number CN218723750U discloses a bearing housing inner diameter detection fixture. This device can drive the movable shaft to rotate in different directions by rotating the rotating handle in different directions, and then through the cooperation of the fixed shaft and the movable shaft, the bearing housing body can be clamped from the inside. The movable shaft can drive the indicating arrow to move on one side of the detection scale. However, there are still the following problems: 1. Since the roundness of the inner diameter of the bearing housing cannot be guaranteed after processing, and this device directly detects the inner diameter of the bearing housing when detecting the inner diameter, thus ignoring the detection of the roundness of its inner diameter, and it is easy to produce defective products. 2. When continuously measuring the inner diameters of multiple bearing housings, manual measurement is used, which not only has low efficiency, but also the high-intensity repetitive work is prone to fatigue, reducing the measurement accuracy.

[0028] In the present invention, the measuring assembly 6 includes a T-shaped seat 34 fixedly connected to the upper surface of the connecting seat 2 by bolts. A T-shaped frame 36 is slidably connected through one side of the T-shaped seat 34. One end of the T-shaped frame 36 is fixedly connected with a square block 38 by bolts. A connecting block 37 is fixedly connected to the T-shaped frame 36 by bolts.

During the extension process, the inner diameter measuring instrument 39 detects the inner diameter of the bearing seat. Through the provided measuring assembly 6, the inner diameter measuring instrument 39 provided therein can detect the inner diameter of the bearing seat, eliminating the need for manual measurement of the inner diameter of each bearing seat one by one, greatly saving the measurement time and thus increasing the efficiency of measuring the inner diameter of the bearing seat.

[0029] In the present invention, the driving assembly 7 includes a gear ring 8 fixedly connected to the lower surface of the rotating seat 3 by bolts. An L-shaped plate 9 is fixedly connected to the lower surface of the connecting seat 2 by bolts. One side of the L-shaped plate 9 is rotatably connected to a rotating shaft 10.

During the rotation of the rotating shaft 10, the gear 11 at its end will rotate. When the gear 11 rotates, the gear ring 8 meshing with it will rotate to drive the rotating seat 3 to rotate. Through the provided driving assembly 7, the rotating seat 3 can be rotated by the first driving motor 12, eliminating the need for manual rotation of the rotating seat 3, saving manpower and increasing the automation effect of the device.

[0030] The present invention is used in the following steps: S1: When it is necessary to detect the inner diameter of the bearing seat, first install the bearing seat to be detected on the fixing assembly 4 at the placement station. First, place the bearing seat on the stepped clamping seat 19, and then rotate the bidirectional lead screw 22 to drive the two sliding plates 16 to approach each other along the sliding rod 15. When the notches 17 on the sliding plates 16 contact the two ends of the bearing seat, the bearing seat can be fixed. S2: Subsequently, the rotating seat 3 is rotated by the driving component 7 by 120 degrees, and the fixing component 4 with the bearing seat installed is rotated in front of the detecting component 5 to detect the inner diameter roundness thereof. By starting the first electric push rod 25 to extend, while the first electric push rod 25 extends, the fixing frame 26 and the square rod 28 at its end will move together towards the bearing seat. When the inclined rod 32 on the square rod 28 is inserted into the inner ring of the bearing seat, the inclined rod 32 is squeezed, and the sliding sleeve 31 thereon moves along the limiting rod 30, thereby squeezing the spring 33 to squeeze the pressure sensor 29, and making its data displayed on the display screen. Subsequently, the second driving motor is started to drive the rotating disc 27 to rotate, and then the inclined rod 32 rotates along the inner wall of the bearing seat; S3: At the placement station, a new bearing seat is placed into the new fixing component 4. After the detection is completed, the rotating seat 3 is rotated by 120 degrees again through the driving component 7, so that the detected bearing seat is sent in front of the measuring component 6. By starting the second electric push rod 35 to extend, the T-shaped seat 34 is driven to extend through the connecting block 37, and during the extension process, the inner diameter measuring instrument 39 detects the inner diameter of the bearing seat; S4: After the measurement is completed, the rotating seat 3 is rotated by 120 degrees again through the driving component 7 to send the measured bearing seat to the placement station, then the measured bearing seat can be taken off, and then a new bearing seat is replaced for detection. In this way, a cycle is formed. When it is necessary to rotate the rotating seat 3, the first driving motor 12 is started to drive the rotating shaft 10 rotatably connected to one side of the L-shaped plate 9 to rotate. During the rotation of the rotating shaft 10, the gear 11 at its end rotates. When the gear 11 rotates, the toothed ring 8 meshing with it rotates to drive the rotating seat 3 to rotate.
