Description

Technical Field

[0001] The utility model relates to a bearing ring manufacturing production line, in particular to a feeding and screening device of a bearing ring lifting device with automatic conveying. Background Art

[0002] The specific production process of bearings: raw materials, inner and outer ring processing, steel ball or roller processing, cage (stamping or solid) processing, bearing assembly, bearing finished product. The traditional ring processing process varies depending on the raw material or blank form. The entire inner and outer ring processing process is: bar or tube material (some bar materials need to be forged and annealed, normalized), turning, heat treatment, grinding, fine lapping or polishing, final inspection of parts, rust prevention, and storage. The blank of the bearing ring stamped out of the sheet is stamped twice after being stamped. Figure 3 The shape shown by the middle number a. One end face maintains the style of the plate and does not form a through hole like the conventional shaft side outer ring. Therefore, further stamping and punching processing is required. In order to reduce the use of manpower and enhance the degree of automation, the bearing ring blank a produced from the previous process will be input into a hopper through a conveying pipeline in various angles, and even two bearing ring blanks a may be nested together. In order to automatically adjust the bearing ring blank a to a suitable angle and feed it into the stamping mechanism, a screening device needs to be designed. Summary of the invention

[0003] The utility model is a feeding and screening device of a bearing ring lifting device which is designed for automatically extracting and adjusting the position of bearing blanks from a hopper in a multiple processing line.

[0004] The utility model provides a feeding and screening device for a bearing ring lifting device, comprising: a collecting barrel, a plate chain conveyor belt, a screener and a feeding track;

[0005] The working belt surface of the plate chain conveyor is tilted and implanted in the aggregate bucket, rotating from bottom to top;

[0006] The screener is arranged on the side of the plate chain conveyor, and the screener is connected to the entrance of the unloading track;

[0007] The unloading track passes through the side wall of the aggregate bucket;

[0008] A bottom block is arranged on the plate of the plate chain conveyor belt, and a side block is arranged on the working frame of the plate chain conveyor belt, and the bottom block and the side block cooperate to lift the bearing ring;

[0009] The filter setting height matches the side stop top height.

[0010] After completing the process from other equipment, the bearing ring blanks will enter the collecting bucket of this device through pipes or through grooves; a part of the belt surface of the plate chain conveyor is inserted into the collecting bucket. When the actual working belt surface of the plate chain conveyor is set to lift, the collecting bucket will be stirred due to the plate chain structure and the raised bottom block on the plate chain, so that the bearing ring blanks in the collecting bucket are lifted by the bottom block and rely on the movable unit composed of the side block, the bottom block and the single plate of the plate chain.

[0011] This movable unit is released as it is lifted upward to the top of the side block; at this time, the bearing ring blank rolls along the angle of the bottom block and slides into the screener; the bearing ring blanks that have passed the screener will be output along the screener and the unloading track to the downstream stamping mechanism, while the bearing ring blanks that have not passed the screener will roll back into the collection bucket.

[0012] Preferably, the angle between the working belt surface of the plate chain conveyor belt and the horizontal plane is between 75° and 85°;

[0013] The middle axis surface of the short side of the screener is parallel to the working belt surface;

[0014] The conveying axis of the screener forms an angle of 30° with the horizontal plane.

[0015] Preferably, the screener comprises a first baffle, a second baffle and a bottom plate;

[0016] The first baffle is fixedly connected to the frame of the plate chain conveyor belt, and has a thickness greater than or equal to 12 mm and less than or equal to 20 mm;

[0017] The top edge of the first baffle connected to the side block is provided with a top edge chamfer, the thickness of the top edge after chamfering is greater than or equal to 6mm and less than or equal to 10mm, and the chamfer is provided with a total length of 50mm;

[0018] The height of the second baffle plate matches the diameter of the bearing ring, and the length is equal to 1.5 times the diameter of the bearing ring;

[0019] The top edge of the second baffle is parallel to the top edge of the first baffle, and is arranged at a height lower than the first baffle;

[0020] The horizontal distance between the second baffle and the first baffle is equal to the thickness of the bearing ring;

[0021] The first baffle plate, the second baffle plate and the bottom plate form a U-shaped groove, and the lower end of the groove is the output and is connected to the unloading track.

[0022] The main working mode of the screener is that due to the boss structure on the outer periphery of the bearing ring blank, when it rolls on the first baffle with the opening facing the frame, it will not be affected and will directly roll through the first baffle and fall back into the collecting bucket. When the surface with the boss faces the frame and rolls on the first baffle and passes the chamfer position, it will slide from the top edge of the first baffle and enter the unloading track.

[0023] Preferably, a filter spring is provided on the frame of the plate chain conveyor belt; the filter spring is provided at a position connected from the left side of the frame to the right side of the frame, so that the filter spring passes through the working belt surface on the projection of the working belt surface and forms an angle of 120° with the bottom block.

[0024] The spring is helpful to knock the stacked sets of bearing ring blanks off the plate chain conveyor belt to prevent the stacked sets of bearing ring blanks from affecting subsequent work.

[0025] Preferably, the thickness of the bottom block matches the thickness of the bearing ring, and the long side of the bottom block forms an angle of 30° with the long side of the plate block of the plate chain conveyor belt; the corner where the bottom block abuts against the filter spring is set to be chamfered.

[0026] As a preference,

[0027] The beneficial effects of the utility model are: improving the work of the bearing ring blank assembly line, reducing the use of manpower, and automatically screening to avoid adverse effects on the stamping mechanism. BRIEF DESCRIPTION OF THE DRAWINGS
