Technical Field

[0001] The utility model relates to the technical field of bearing production and processing, in particular to a roundness detection device for bearing ball production. Background Art

[0002] Ball bearings are a type of rolling bearings. The balls are installed between the inner and outer steel rings and can withstand large loads. They are also called ball bearings. Currently, bearings are widely used in many industries, so it is necessary to optimize bearing production.

[0003] For example, a Chinese utility model patent with announcement number CN216115900U discloses a bearing ball roundness detection device. Although the above-mentioned prior art has an infrared ranging sensor, motor a and motor b that can adjust the position of the turntable according to the size of the ball to detect the roundness, and the detection effect is good, the speed of detecting the bearing balls one by one is too slow. A bearing requires multiple balls to be assembled, so the production quantity of balls is also huge. The inability to perform multiple unified detections on the balls will result in low detection efficiency, which will affect the efficiency of the entire bearing production and processing. Therefore, it is necessary to design a ball production roundness detection device that can perform unified detection of multiple balls. Utility Model Content

[0008] Through the above technical solution, the ball can be clamped and fixed by closing the upper mold and the lower mold.

[0009] As a further improvement of the above solution, a plurality of detection grooves for detecting the roundness of the bearing balls are provided on one side of the lower mold and the upper mold, and a plurality of limit holes matched with adjacent detection grooves are provided on the two sealing plates.

[0010] Through the above technical solution, the upper mold and the lower mold adapted to the ball can clamp the ball, and the ball will not shake inside.

[0011] As a further improvement of the above scheme, a water storage box is provided on one side of the upper mold, and a plurality of thin water tubes are provided between the upper mold and the water storage box. One ends of the plurality of thin water tubes pass through the upper mold and extend to the interior of an adjacent detection slot, and the other ends of the plurality of thin water tubes are connected to the water storage box.

[0012] Through the above technical solution, the water inside the water storage box will enter the detection tank through the thin water pipe, which is convenient for more precise roundness detection.

[0013] As a further improvement of the above scheme, the second detection component includes a small water pump arranged on one side of the detection box, a water outlet pipe fixedly connected to the water outlet end of the small water pump, a flow monitor installed on the water outlet pipe, and a water inlet pipe fixedly connected to the water inlet end of the small water pump, one end of the water outlet pipe is fixedly connected to the water storage box, and one end of the water inlet pipe is fixedly connected to the interior of the detection box.

[0014] Through the above technical solution, a small water pump delivers the water inside the test box into the test tank, and the roundness of the ball can be obtained in conjunction with a flow monitor.

[0015] As a further improvement of the above solution, the fixing assembly includes a rotating shaft rotatably installed on both sides of the lower mold and a hook plate fixedly installed on one side of each rotating shaft, and the hook plate is arranged in an "L" shape.

[0016] Through the above technical solution, the hook plate will hook the edge of the upper mold, so that the upper mold and the lower mold cannot be separated.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model sets a first detection component, a second detection component and a fixing component. When the roundness detection is performed on multiple bearing balls, the first detection component is opened to put the balls inside and then closed and shaken. When there is a shaking sound inside, it means that the roundness of the balls is unqualified. When a more precise roundness detection is required, the second detection component is started to send water into the first detection component. If the balls have qualified roundness and uniform size, the amount of water entering the first detection component is fixed. When the amount of water entering is not fixed, the roundness of the balls is different. This arrangement can not only perform roundness detection on multiple balls at the same time, but also perform roundness detection to different degrees according to the detection requirements.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3 A roundness detection device for bearing ball production in this embodiment includes a detection box 1. A first detection component is provided inside the detection box 1 for clamping multiple bearing balls at the same time and simply detecting the roundness. A second detection component is provided on one side of the first detection component for cooperating with the first detection component to perform fine roundness detection on multiple bearing balls at the same time. A fixing component is provided on the first detection component to prevent the first detection component from being separated after clamping the balls.

[0026] Combination Figure 1-Figure 3A support column 5 is fixedly installed inside the detection box 1. The first detection component includes a lower mold 201 arranged on one side of the support column 5 and an upper mold 202 arranged on one side of the lower mold 201. A sealing plate 6 is fixedly installed on one side of the lower mold 201 and one side of the upper mold 202. A plurality of detection grooves for detecting the roundness of the bearing ball are provided on one side of the lower mold 201 and the upper mold 202. A plurality of limiting holes matched with adjacent detection grooves are provided on the two sealing plates 6. The upper mold 202 and the lower mold 201 matched with the ball can clamp the ball, and the ball will not shake inside.

[0027] Combination Figure 1-Figure 3 A water storage box 7 is provided on one side of the upper mold 202, and a plurality of thin water tubes 8 are provided between the upper mold 202 and the water storage box 7. One ends of the plurality of thin water tubes 8 all penetrate the upper mold 202 and extend to the interior of the adjacent detection tank, and the other ends of the plurality of thin water tubes 8 are all connected to the water storage box 7. The second detection component includes a small water pump 301 arranged on one side of the detection box 1, a water outlet pipe 302 fixedly connected to the water outlet end of the small water pump 301, a flow monitor 303 installed on the water outlet pipe 302, and a water inlet pipe 304 fixedly connected to the water inlet end of the small water pump 301. One end of the water outlet pipe 302 is fixedly connected to the water storage box 7, and one end of the water inlet pipe 304 is fixedly connected to the interior of the detection box 1. The water inside the water storage box 7 will enter the interior of the detection tank through the thin water tubes 8, which is convenient for more precise roundness detection. The small water pump 301 sends the water inside the detection box 1 into the interior of the detection tank, and the roundness of the ball can be obtained in conjunction with the flow monitor 303.

[0028] Combination Figure 2 The fixed component includes a rotating shaft 401 rotatably installed on both sides of the lower mold 201 and a hook plate 402 fixedly installed on one side of each rotating shaft 401. The hook plate 402 is set in an "L" shape. The hook plate 402 will hook the edge of the upper mold 202, so that the upper mold 202 and the lower mold 201 cannot be separated.

[0029] The implementation principle of a roundness detection device for bearing ball production in the embodiment of the present application is as follows: when it is necessary to perform a unified roundness detection on multiple bearing balls of the same size, prepare the upper mold 202 and the lower mold 201 of the bearing balls of the same size, open the upper mold 202, put the balls into the detection groove of the lower mold 201, close the upper mold 202, and rotate the hook plate 402 to fix the lower mold 201 and the upper mold 202. In this way, the closed mold is shaken. If there is a shaking sound and collision inside the mold, it means that the roundness of the balls is different. Because the different roundness makes it impossible to fill the inside of the detection groove, the balls that do not meet the roundness standard can be screened out by screening twice. When a more detailed roundness detection of the balls is required, Start the small water pump 301, and send the water inside the test box 1 into the water storage box 7 through the outlet pipe 302, and then send it into the test tank through the thin water pipe 8, and observe the flow monitor 303. If the roundness of the ball meets the standard, the amount of water sent in should be the same fixed value as before, because the ball will fill the space inside the test tank and water cannot enter the test tank. If the value is different, then the roundness of the ball is different, because if the volume is the same but the roundness is different, a sound will be made when the mold is shaken. This arrangement allows the first detection component to cooperate with the second detection component not only to perform roundness detection on multiple balls at the same time, but also to perform more detailed detection of whether the roundness meets the standard according to the detection requirements.

[0030] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
