Description

Technical Field

[0001] The utility model relates to the technical field of bearing seat manufacturing, in particular to a screening device for bearing seat production. Background Art

[0002] The bearing seat for rollers is usually formed by metal disc materials through a die through multiple steps of stamping, stretching, shaping, punching, trimming, etc.

[0003] During the actual punching process of the bearing seat, some punching waste is often stuck in the opened hole and cannot be separated. After trimming, the bearing seat will be pushed to the guide rack by the robot, and the bearing seat moves downward along the inclined surface of the guide rack and finally enters the receiving box. The staff needs to screen out all the bearing seats with punching waste stuck in the receiving box one by one, and then use a knocking tool to knock the punching waste out of the hole. Manual screening is troublesome, labor-intensive and easy to cause omissions. Therefore, the present application provides an automatic screening and knocking device for bearing seat production to meet the needs. Utility Model Content

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a screening device for bearing seat production, comprising a material guide rack with an eight-shaped feed section and a material guide section arranged obliquely downward, and also comprising a screening unit installed on the material guide rack, wherein the screening unit is used to separate bearing seats with punching waste stuck in them from bearing seats without punching waste stuck in them.

[0006] As a preferred implementation manner in this embodiment, the screening unit includes a rotating plate arranged in the open cavity of the material guide section, a rotating drum is fixed at the bottom of the rotating plate at a position deviating from the center, the inner cavity of the rotating drum is penetrated by a rotating shaft, both ends of the rotating shaft are fixedly connected to the material guide frame, the rotating drum is rotatably connected to the rotating shaft through internally arranged bearings, a weight-adding block is fixed at the bottom of the rotating plate and close to the rotating drum, upper and lower stop bars are arranged at both ends of the rotating plate, and contact stop bars corresponding to the upper stop bar and the lower stop bar are provided on the inner wall of the open cavity of the material guide section.

[0009] In summary, the technical effects and advantages of the utility model are:

[0010] The utility model has a reasonable structure, and the screening unit can separate the bearing seat with punching waste stuck and the bearing seat without punching waste stuck, without manual screening operation;

[0011] In the utility model, the first stop block and the second stop block are provided to prevent the rotating plate from over-rotating, which would increase the interval time for it to return to its original state. The increased interval time would reduce the screening efficiency of the bearing seat, making it unable to keep up with the stamping speed of the bearing seat and causing material accumulation. The installation positions of the first stop block and the second stop block are determined according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] 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.

[0019] Example: Reference Figure 1-3A screening device for bearing seat production shown in the figure includes a material guide frame with an eight-shaped feed section 1 and a material guide section 3 arranged obliquely downward, and also includes a screening unit 2 installed on the material guide frame, and the screening unit 2 is used to separate the bearing seats with punching waste stuck in them from the bearing seats without punching waste stuck in them.

[0020] As a preferred implementation in this embodiment, Figure 1-4 As shown, the screening unit 2 includes a rotating plate 21 arranged in the open cavity of the material guide section 3, a rotating drum 25 is fixed at the bottom of the rotating plate 21 at a position offset from the center, the inner cavity of the rotating drum 25 is penetrated by a rotating shaft 26, both ends of the rotating shaft 26 are fixedly connected to the material guide frame, the rotating drum 25 is rotatably connected to the rotating shaft 26 through bearings arranged inside, a weight block 22 is fixed at the bottom of the rotating plate 21 and close to the rotating drum 25, and upper baffles 23 and lower baffles 24 are arranged at the two ends of the rotating plate 21, and a contact baffle 29 corresponding to the upper baffle 23 and the lower baffle 24 is provided on the inner wall of the open cavity of the material guide section 3.

[0021] When the bearing seat is pushed onto the guide section 3, its bearing seat will move downward along the inclined surface. When it moves to the rotating plate 21, if there is punching waste stuck in the hole of this bearing seat, its own weight is heavy. When it moves to the right side of the rotating drum 25, its rotating plate 21 will rotate, and the right end of the rotating plate 21 will rotate downward, and the bearing seat sliding on it will slide down along its inclined surface into the material receiving bucket below, and then the rotating plate 21 will rotate in the opposite direction and return to its original position under the action of the gravity of the weight-increasing block 22. At this time, the lower end of the upper stop bar 23 and the upper end of the lower stop bar 24 respectively contact the corresponding contact stop bar 29, and the inclination of the rotating plate 21 is consistent with the guide section 3. If there is no punching waste stuck in the hole of this bearing seat, its own weight is relatively light, and the rotating plate 21 does not rotate, and its bearing seat will move directly along the guide section to the material receiving box, and the screening unit 2 can automatically screen according to gravity without manual operation.

[0022] As a preferred implementation in this embodiment, Figure 4 As shown, a first stopper 27 is fixed on the inner wall of the rotating drum 25 , and a second stopper 28 is fixed on the outer wall of the rotating shaft 26 .

[0023] The first stopper 27 and the second stopper 28 are provided to prevent the rotating plate 21 from over-rotating, which would increase the interval time for it to return to its original state. The increased interval time would reduce the screening efficiency of the bearing seat, making it unable to keep up with the stamping speed of the bearing seat and causing material accumulation. The positions of the first stopper 27 and the second stopper 28 are set as needed, so that the rotating plate 21 can be rotated by a certain angle (the rotating plate 21 is in an inclined state at this time) to guide the bearing seat into the receiving barrel, and at the same time, the interval time for the rotating plate 21 to return to its original position is minimized.

[0024] As a preferred implementation in this embodiment, Figure 1 As shown, a baffle 4 is provided at the bottom of the material guide frame.

[0025] It blocks the bearing seat that slides down obliquely, so as to prevent the bearing seat from sliding down obliquely and moving laterally beyond the size of the receiving barrel, thereby preventing the bearing seat from being accurately inserted into the barrel.

[0026] It should be noted that an elastic buffer pad is provided on the baffle 4, which can collide with the bearing seat to reduce its kinetic energy, rather than causing a louder noise when colliding with the bearing seat in the receiving barrel.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
