The limiting component ensures that the bearing ring does not wobble during measurement, improving measurement accuracy.

Description

Technical Field

[0001] This utility model relates to the field of bearing ring processing technology, specifically to a bearing ring inner and outer diameter measuring device. Background Technology

[0002] In the production of bearing rings, measuring the inner and outer diameters is a core aspect of quality control, directly impacting bearing performance, lifespan, and assembly reliability. For example, the bearing's inner diameter needs to fit tightly with the shaft (interference or transition fit), and the outer diameter needs to match the housing bore. Dimensional deviations can lead to: for example, too tight: installation difficulties, stress deformation, and accelerated wear; too loose: bearing slippage, abnormal noise, or even detachment (such as the risk of failure in automotive wheel bearings). Therefore, rapid and accurate measurement of the inner and outer diameters is a crucial aspect of quality control.

[0003] Traditional measurement methods mainly rely on manual handheld calipers or micrometers to measure each bearing individually, which has the following problems: First, manual measurement requires frequent picking up and putting down of the bearing rings, resulting in slow measurement speed and difficulty in matching the cycle time of automated production lines. Second, manual measurement is prone to errors due to tilting or movement of the bearing rings during measurement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bearing ring inner and outer diameter measuring device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bearing ring inner and outer diameter measuring device includes an operating table with a groove on its surface. A rotating shaft is rotatably connected within the groove. A rotating disk is fixed to the side of the rotating shaft, and four placement slots are equidistantly arranged in a circular array on the surface of the rotating disk. One end of each groove is connected to a feeding conveyor belt, and the other end is connected to a discharging conveyor belt. A limiting component is provided on the side wall of the groove.

[0007] The feeding conveyor belt transports the bearing ring to the placement slot opposite it. After the rotary disc rotates 90°, it works with the limiting component to limit the bearing ring for measurement. The rotary disc continues to rotate 90° so that the placement slot is opposite the discharge conveyor belt, and the bearing ring is output.

[0008] Furthermore, the limiting component includes rubber rollers, a connecting rod, and a spring; the connecting rod is inserted into the side wall of the groove, and one end of the connecting rod is rotatably connected to multiple rubber rollers; the other end of the connecting rod is connected to the operating table via a spring; the connecting rod adopts an "I"-shaped structure with an arc-shaped top.

[0009] Furthermore, a handwheel is fixed to the end of the rotating shaft, and a locking assembly is provided on the side of the rotating shaft.

[0010] Furthermore, the locking assembly includes a pawl and a ratchet; four pawls are evenly distributed on the outside of the ratchet; the ratchet is fixed to the side of the rotating shaft, and the ratchet is located between the rotating disk and the operating table; the ratchet is engaged with at least one pawl, and the pawl is rotatably connected to the groove by a torsion spring.

[0011] Furthermore, the operating surface of the operating table has an inclined structure, and the surface of the operating table is provided with grooves.

[0012] Furthermore, the placement groove adopts a half-circular structure, and the inner wall of the placement groove is provided with a gasket.

[0013] This invention provides a device for measuring the inner and outer diameters of bearing rings. Compared with the prior art, it has the following advantages:

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Combination Figures 1-4 As shown, this utility model provides a bearing ring inner and outer diameter measuring device, including an operating table 400. To facilitate operation on the operating table 400, the operating surface of the operating table 400 is inclined. A groove 401 is formed on the surface of the operating table 400. Specifically, the surface of the operating table 400 has a central circular structure, and rectangular opening grooves 401 are formed at both ends of the circular structure. That is, the groove 401 consists of a connected circular groove and two rectangular grooves. A rotating shaft 500 is rotatably connected within the groove 401. A rotating disk 300 is fixed to the side of the rotating shaft 500, and four placement slots 301 are equidistantly arranged in a circular array on the surface of the rotating disk 300.

[0024] One end of the groove 401 is connected to the feeding conveyor belt 100, and the other end of the groove 401 is connected to the discharging conveyor belt 600; specifically, the feeding conveyor belt 100 is inserted into one of the rectangular grooves of the groove 401, and the discharging conveyor belt 600 is inserted into the other rectangular groove of the groove 401.

[0025] The side wall of the groove 401 is provided with a limiting component 700; the limiting component 700 cooperates with the placement groove 301 to limit and fix the bearing ring 200. Specifically, the limiting component 700 includes rubber rollers 701, connecting rods 702 and springs 703; the connecting rod 702 is inserted into the side wall of the groove 401, and one end of the connecting rod 702 is rotatably connected to multiple rubber rollers 701; the other end of the connecting rod 702 is connected to the operating table 400 by a spring 703; the connecting rod 702 adopts an "I"-shaped structure with an arc-shaped top. It should also be noted that this application generally processes bearing rings 200 with the same or similar dimensions. The processed bearing rings 200 can be placed between the placement groove 301 and the recess 401, and can enter the limiting component 700 and be limited by the abutment of the limiting component 700. It is usually only used to process bearing rings 200 with the same diameter as the placement groove 301. When the limiting component 700 moves to the highest point, it needs to not obstruct the entry of the bearing rings 200.

[0026] The feeding conveyor belt 100 transports the bearing ring 200 into the placement groove 301 opposite to it. After the rotating disk 300 rotates 90°, it cooperates with the limiting component 700 to limit the bearing ring 200 for measurement. The rotating disk 300 continues to rotate 90° so that the placement groove 301 is opposite to the discharge conveyor belt 600, and the bearing ring 200 is output.

[0027] To facilitate hand-held rotation by the operator, a handwheel 501 is fixed to the end of the rotating shaft 500, and a locking assembly 800 is provided on the side of the rotating shaft 500. There is damping between the groove 401 of the operating table 400 and the rotating disk 300, so the rotating shaft 500 will not rotate on its own. The locking assembly 800 includes a pawl 801 and a ratchet 802. Four ratchet blocks are evenly distributed on the outside of the ratchet 802. The ratchet 802 is fixed to the side of the rotating shaft 500 and is located between the rotating disk 300 and the operating table 400. The ratchet 802 engages with at least one pawl 801, which is rotatably connected to the groove 401 via a torsion spring, effectively preventing reverse rotation. It locks after rotating 90°, ensuring that each rotation is 90°.

[0028] In order to accommodate the bearing ring 200 with a circular structure and reduce damage to the bearing ring 200, the placement groove 301 adopts a half-circular structure, and the inner wall of the placement groove 301 is provided with a gasket.

[0029] In use, the bearing ring 200 to be measured is first placed on the feed conveyor belt 100 and slowly and evenly conveyed until it reaches the placement groove 301 opposite to the feed conveyor belt 100. At this time, the operator holds the handwheel 501 and rotates it 90° counterclockwise, causing the pawl 801 to engage the ratchet block of the next ratchet 802. Simultaneously, the second bearing ring 200 enters the other placement groove 301 opposite to the feed conveyor belt 100. At the same time, the first bearing ring 200 entering the placement groove 301... The bearing ring 200 is positioned on the side of the limit assembly 700 and contacts the rubber roller 701. The connecting rod 702 presses the spring 703, and the spring force of the spring 703 limits the bearing ring 200. At this time, the operator can use tools such as vernier calipers or micrometers to measure the inner and outer rings of the bearing ring 200. After the measurement is completed, continue to rotate counterclockwise by 90° so that the measured bearing ring 200 reaches the discharge conveyor belt 600, and the measured bearing ring 200 can be output. The second bearing ring 200 reaches the measurement position on the side of the limit assembly 700 and waits for measurement.

[0030] In this application, the feeding conveyor belt 100 and the discharging conveyor belt 600 extend into both sides of the bottom end of the rotary disk 300, or a guide slope (such as a 45° chamfer) is added to the edge of the rectangular extension groove, and the auxiliary bearing ring 200 slides into the placement groove 301.
