Description

Technical Field

[0001] The invention belongs to the technical field of stamping, and in particular relates to a bearing retainer pressure slope pre-positioning device. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] At present, the bearing retainer needs to be inspected for quality before the slope pressing process, and the retainer needs to be positioned before the inspection for quality, so that the bearing retainer can perfectly match the inspection mold and prevent damage to the parts during the slope pressing.

[0004] The existing retainer pre-positioning device is a punching needle parallel to the conveyor belt set at the end of the conveyor belt. The retainer is rotated to a specified slope angle through repeated impacts of the punching needle. When the retainer angle is greatly offset, multiple impacts are required to complete the alignment. The punching needle alignment method often deviates, causing the slope to damage the product, and multiple impacts result in very low alignment efficiency. Summary of the invention

[0005] In view of the above problems, the present invention provides a bearing retainer slope pre-positioning device, and provides a pre-positioning device that synchronously carries out the conveying and alignment of the retainer. Under the action of the alignment rod, the retainer rotates during the conveying process, so that the retainer is aligned, which is convenient for the next step of detection, and solves the problem of low alignment efficiency of the retainer. At the same time, it avoids rigid contact between the alignment device and the retainer, and solves the problem of damage to the retainer during alignment.

[0008] The alignment rod is composed of an alignment section, a fixed section and an adjustment section, which are fixedly connected in sequence. The alignment section and the fixed section are both cylinders, and the ends of the alignment section are provided with arc-shaped chamfers. The outer side surface of the fixed section is provided with external threads, and the alignment fixing frame is evenly provided with through holes, and the through holes are provided with internal threads. The external threads on the outer side surface of the fixed section cooperate with the internal threads on the alignment fixing frame; an angle is set between the alignment rod and the conveyor belt.

[0010] Furthermore, there are two of each of the first roller seat and the second roller seat, and the first roller seat and the second roller seat are distributed on both sides of the support frame.

[0011] Furthermore, the driving roller is connected to a driving mechanism, which includes a driving motor and a transmission. The transmission is detachably connected and fixed to one of the first roller seats and is located on a side away from the support frame. A driving motor is arranged below the transmission.

[0012] Furthermore, the distance between the limiting guide rails is a size that allows a single retaining rack to pass through.

[0013] Furthermore, the support frame and the position-limiting guide rail are fixedly connected via a position-limiting connecting block, and the position-limiting connecting block is detachably connected to the support frame and the position-limiting guide rail.

[0014] Furthermore, at least two limiting connection blocks are provided on each side of the support frame and are evenly arranged along the longitudinal direction of the support frame.

[0017] Furthermore, the retaining frame is a truncated cone-shaped hollow structure, a plurality of window holes are arranged on the side surface of the retaining frame, and window beams are arranged between adjacent window holes.

[0018] Compared with the prior art, the present invention has the following advantages and positive effects:

[0019] The present invention provides a positioning rod, and the positioning rod contacts the window beam of the bearing retainer, so that the retainer rotates synchronously when moving on the conveyor belt, so that the retainer stops rotating when the window hole is facing the limiting guide rail, and then continues to move. Multiple retainers can be placed on the conveyor belt at the same time, which improves the positioning efficiency of the retainer. The positioning rod is detachably connected to the positioning fixing frame, and the positioning rod is threaded, and the distance between the retainer and the limiting guide rail on the other side can be adjusted according to the different sizes of retainers, so the adaptability is strong.
