Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to an automatic processing device for bearing back grooves. Background Technology

[0002] The bearing bush is the part of a sliding bearing that contacts the journal. It is shaped like a tile-like semi-cylindrical surface, very smooth, and generally made of wear-resistant materials such as bronze or anti-friction alloys. In special cases, it can be made of wood, engineering plastics, or rubber. Bearing bushes come in two types: integral and split. Integral bearing bushes are usually called bushings, and they are available with or without oil grooves. The bearing bush and journal use a clearance fit and generally do not rotate with the shaft.

[0003] The existing technology has the following problems:

[0004] Currently available automatic machining devices for bearing bush back grooves are generally fixed during use and cannot be moved. The bearing bush to be processed needs to be manually pushed by hand. Manual pushing of the bearing bush is time-consuming, labor-intensive, and prone to safety accidents, resulting in poor safety and reliability. In addition, traditional technology usually involves installing a single bearing bush in a small milling machine, milling one end, and then clamping it again to mill the other end, which is cumbersome and inconvenient. Utility Model Content

[0013] Compared with the prior art, the present invention provides an automatic processing device for bearing back grooves, which has the following advantages:

[0014] This automatic processing device for bearing back grooves features a convenient processing component. During processing, a motor located on one side of the base is activated, causing a lead screw to rotate. This moves a moving block, which in turn moves a connecting block, controlling the movement of a support plate fixed to the top of the connecting block. This, in turn, moves the position of the processing component. A hydraulic cylinder located on the top of the support plate then moves a connecting block located inside the support plate. Because the processing component is fixed to one side of the connecting block, its height can be controlled, facilitating adjustment and improving equipment safety.

[0015] This automatic machining device for bearing back grooves features adjustable clamps. During operation, an electric telescopic rod located on one side of the support plate is activated according to the size of the bearing. This telescopic rod controls the movement of a push block, thereby adjusting the distance between the two clamps. A telescopic cylinder is activated to control the clamps to hold the bearing, facilitating the clamping of bearings of different sizes. After one side of the bearing is machined, a rotary cylinder located inside the protective block is activated, causing a rotating shaft to rotate, which in turn controls the rotation of the clamps. This allows for adjustment of the machined surface of the bearing, improving machining efficiency. Attached Figure Description
