Description
Technical Field
[0001] This utility model relates to the field of steel ball inspection technology, and in particular to a novel steel ball inspector for deep groove ball bearings. Background Technology
[0002] Deep groove ball bearings are a type of rolling bearing, originally called single-row radial ball bearings. They are one of the most widely used rolling bearings, characterized by low frictional resistance and high speed. Deep groove ball bearings are used to support rotating parts and reduce friction.
[0003] Deep groove ball bearings mainly consist of an outer ring, an inner ring, a set of steel balls, and a cage. Currently, after steel ball production, workers need to inspect the roundness of the steel balls. The traditional method for checking the roundness of steel balls is to use a roundness tester to check each ball individually. However, this method involves cumbersome procedures and can only inspect one ball at a time, which is time-consuming, labor-intensive, and reduces inspection efficiency, resulting in poor performance. Therefore, a new type of deep groove ball bearing steel ball inspection device is urgently needed to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide a new type of steel ball inspector for deep groove ball bearings. However, it can only inspect one steel ball at a time, which is time-consuming and labor-intensive, reduces the efficiency of steel ball inspection, and has poor performance.
[0005] To achieve the above objectives, a novel steel ball inspector for deep groove ball bearings is provided, comprising: a housing, on which a roundness inspection plate is fixedly installed, and inside the housing are a pusher assembly and a steel ball drop buffer assembly;
[0006] The feeding assembly includes an electric push rod, which is fixedly installed on the outer wall of the housing. A first connecting block is fixedly installed on the output shaft of the electric push rod. A first connecting rod and a connecting rod are fixedly installed on the outer wall of the first connecting block. A second connecting block is fixedly installed at the bottom end of the connecting rod.
[0007] According to the novel steel ball inspector for deep groove ball bearings, a second connecting rod is fixedly installed on the outer wall of the second connecting block, and an upper pusher plate is fixedly installed on the other end of the first connecting rod.
[0008] According to the novel steel ball inspector for deep groove ball bearings, a lower pusher plate is fixedly installed at the other end of the second connecting rod, and the outer wall of the roundness inspection plate is slidably connected to the upper pusher plate.
[0009] According to the novel steel ball inspector for deep groove ball bearings, an upper door and a lower door are provided on the side wall of the housing, and an upper stroke groove and a lower stroke groove are provided on the outer wall of the housing. The inner wall of the upper stroke groove is slidably connected to the first connecting rod.
[0010] According to the aforementioned novel steel ball inspector for deep groove ball bearings, the inner wall of the lower stroke groove is slidably connected to the second connecting rod, and a support leg is fixedly installed on the outer wall of the bottom of the housing.
[0011] According to the novel steel ball inspector for deep groove ball bearings, the steel ball drop buffer assembly includes a buffer plate, a rubber plate is fixedly installed on the upper surface of the buffer plate, and a buffer spring is fixedly installed on the lower surface of the buffer plate.
[0012] According to the novel steel ball inspector for deep groove ball bearings, a groove is provided on the inner wall of the bottom of the housing, the bottom end of the buffer spring is fixedly installed on the inner wall of the groove, and the inner side wall of the housing is slidably connected to the buffer plate.
[0013] The above-mentioned solution has the following beneficial effects:
[0014] This invention incorporates a pusher assembly and a roundness inspection plate. This design effectively checks the roundness of steel balls by ensuring they can pass through the circular holes on the roundness inspection plate, eliminating the need for a roundness meter. This simplifies the inspection process and allows for simultaneous inspection of multiple steel balls in a single run, improving inspection efficiency. Furthermore, the pusher assembly simultaneously pushes out steel balls that meet the roundness inspection plate along with those that do not, eliminating the need for manual picking and reducing labor intensity. The overall effect is excellent.
[0015] This invention incorporates a steel ball drop buffer assembly. This design effectively buffers the steel balls that have passed the roundness test and fallen to the bottom of the outer casing, further protecting the steel balls, preventing damage, improving the yield rate during steel ball testing, and demonstrating good performance.
[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] Reference Figure 1-4 This utility model embodiment provides a novel steel ball inspector for deep groove ball bearings, comprising: a housing 1, a roundness inspection plate 2 fixedly installed on the inner wall of the housing 1, a roundness detection hole on the roundness inspection plate 2, the size of the detection hole being the qualified standard value of the roundness of the steel ball, and a pusher assembly 5 and a steel ball drop buffer assembly 6 provided inside the housing 1.
[0026] The pusher assembly 5 includes an electric pusher 51, which is the power source for driving the upper pusher plate 55 and the lower pusher plate 56 to move. The electric pusher 51 is fixedly installed on the outer wall of the housing 1, and the outer wall of the electric pusher 51 is fixedly connected to the housing 1. The output shaft of the electric pusher 51 is fixedly installed with a first connecting block 52. A first connecting rod and a connecting rod 54 are fixedly installed on the outer wall of the first connecting block 52. A second connecting block 53 is fixedly installed at the bottom end of the connecting rod 54. The connecting rod 54 is used to connect the first connecting block 52 and the second connecting block 53. A second connecting rod is fixedly installed on the outer wall of the second connecting block 53. The upper pusher plate 55 is fixedly installed at the other end of the first connecting rod, and the lower pusher plate 56 is fixedly installed at the other end of the second connecting rod. The outer wall of the roundness inspection plate 2 is slidably connected to the upper pusher plate 55.
[0027] The outer casing 1 has an upper door 4 and a lower door 7 on its side wall. The upper door 4 is the discharge point for non-standard steel balls, and the lower door 7 is the discharge point for standard steel balls. The outer wall of the outer casing 1 has an upper stroke groove and a lower stroke groove. The upper stroke groove is located above the side wall of the outer casing 1, and the lower stroke groove is located below the side wall of the outer casing 1. The inner wall of the upper stroke groove is slidably connected to the first connecting rod, and the inner wall of the lower stroke groove is slidably connected to the second connecting rod. The outer wall at the bottom of the outer casing 1 is fixedly installed with a support leg 3.
[0028] The steel ball drop buffer assembly 6 includes a buffer plate 61, a rubber plate 62 fixedly installed on the upper surface of the buffer plate 61, the rubber plate 62 provides the initial buffering for the falling steel ball, and a buffer spring 64 fixedly installed on the lower surface of the buffer plate 61, the buffer spring 64 provides the secondary buffering for the falling steel ball. The buffer spring 64 is the main buffering component, and the rubber plate 62 is the secondary buffering component. The combination of the rubber plate 62 and the buffer spring 64 achieves a multi-stage buffering effect. A groove 63 is provided on the inner wall of the bottom of the outer shell 1, and the bottom end of the buffer spring 64 is fixedly installed on the inner wall of the groove 63. The inner wall of the outer shell 1 is slidably connected to the buffer plate 61.
[0029] Working principle: First, place the steel ball to be tested on the roundness inspection plate 2. Part of the steel ball to be tested will fall directly to the bottom of the outer shell 1 through the roundness detection hole on the roundness inspection plate 2. Open the upper door 4 and the lower door 7, and then start the electric push rod 51. The output shaft of the electric push rod 51 pulls the first connecting block 52. The first connecting block 52 drives the upper push plate 55 to move on the roundness inspection plate 2 through the first connecting rod. The upper push plate 55 pushes the steel ball still on the roundness inspection plate 2, so that the steel ball that has not yet fallen to the bottom of the outer shell 1 passes through the roundness detection hole on the roundness inspection plate 2. The steel ball that meets the roundness will fall to the bottom of the outer shell 1 through the detection hole. The steel ball that does not meet the roundness will be pushed out of the device by the upper push plate 55.
[0030] The first connecting block 52 drives the second connecting block 53 to move synchronously through the connecting rod 54. The second connecting block 53 drives the lower pusher plate 56 to move through the second connecting rod, so that the steel ball falling on the rubber plate 62 is pushed out of the device. When the round steel ball falls to the bottom of the outer shell 1 through the detection hole, it will squeeze the buffer plate 61 on which the rubber plate 62 is set. The buffer plate 61 moves down and at the same time squeezes the buffer spring 64 set on the lower surface of the buffer plate 61, so that the buffer spring 64 is in a compressed state. The gravitational potential energy generated by the steel ball falling to the bottom of the outer shell 1 is converted into elastic potential energy on the buffer spring 64 and temporarily stored on the buffer spring 64. Then, the energy is released through the compression and stretching of the buffer spring 64 to complete the buffering of the steel ball.
[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
