Description

Technical Field

[0001] This utility model relates to the field of bearing bar processing, and in particular to bearing bar conveying assembly. Background Technology

[0002] Bearing bar stock typically refers to metal bars used in the manufacture of bearings, primarily for producing components such as rings, balls, and rollers in rolling bearings. In traditional machining, the removal of surface oxide film from bar stock is usually achieved by turning on a lathe. On a typical lathe, the bar stock is secured by clamping devices on both sides, and a cutting tool is placed on the workpiece. As the workpiece rotates, the cutting tool moves linearly along the leadscrew, removing the surface oxide film and cracks. However, lathes have significant limitations in bar stock removal because industrial applications often require long and slender bars, often exceeding 4 meters in length, which is impossible for some lathes. Furthermore, clamping and fixing long and slender bars on a lathe results in larger tolerances due to their own weight, severely compromising the appearance and performance of the workpiece. While some large lathes can process these long and slender bars, the machining process is difficult and time-consuming, leading to low efficiency and significantly impacting production schedules. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a bearing bar conveying assembly that is suitable for slender bars, avoids bar deformation, and has higher efficiency.

[0004] To achieve the above objectives, this utility model provides a bearing bar conveying assembly, including an operating table, a base and a guide on the operating table, the base and the guide being spaced apart along the length of the operating table, the base being provided with a rolling wheel driven synchronously by a chain belt, the rolling wheel being provided with a limiting groove for laterally limiting the bar, and the guide including a lifting and lowering abutment part, the abutment part being slidably abutting against the top of the bar.

[0005] The advantages of the above technical solution are as follows: by setting bases and guides spaced apart along the length of the operating table, bar stock can be placed on the bases, which can meet the needs of conveying ultra-long bar stock. The rolling wheels are driven to rotate synchronously by the chain belt, and the limiting grooves achieve lateral limiting. The upper abutment part can be raised and lowered to slide and abut, forming the guiding movement of the bar stock. The spaced bases form multi-point support, which avoids bending and deformation of slender bar stock due to its own weight, greatly reduces processing tolerance, ensures the appearance and performance stability of the workpiece, and has a simple structure, reduces clamping and adjustment time, significantly improves production rhythm, and effectively solves the problems of limited length, serious deformation and low efficiency in traditional processing.

[0006] The present invention can be further configured such that: the abutting part is cylindrical and rotatably positioned above the base, and a recess is formed in the middle of the abutting part that is opposite to the limiting groove.

[0007] With further design, the cylindrical rotating contact part and the rolling wheel limiting groove cooperate to form a better lateral limit for the slender bar. The rotating design allows the contact part to move synchronously with the bar, avoiding wear caused by sliding friction. Combined with multi-point interval support, it makes the bar more stable and smooth to transport.

[0008] The present invention can be further configured such that: the guide includes a connecting shaft and a connecting bearing, the connecting shaft passes through the abutting part and is rotatably connected to it through the connecting bearing.

[0009] With further design, a cylindrical abutment part is inserted through the connecting shaft, forming a low-friction rotating pair through the connecting bearing. This makes the abutment part rotate more smoothly when it rotates synchronously with the bar stock, avoiding mutual wear caused by local squeezing due to jamming.

[0010] The present invention can be further configured as follows: a long frame for the guide components is provided on the operating table, the guide component includes a cylinder and a mounting plate, the cylinder passes through the long frame and is connected to the upper end of the mounting plate, and the connecting shaft is provided at the lower end of the mounting plate.

[0011] With further design, the long frame of the operating table provides a spaced support base for the guide. The cylinder of the guide passes through the long frame and is connected to the mounting plate, which can flexibly adjust the height of the contact part to adapt to bars of different diameters. The connecting shaft at the lower end of the mounting plate cooperates with the connecting bearing to allow the cylindrical contact part to rotate smoothly, and the central concave part is precisely aligned with the limiting groove.

[0012] The present invention can be further configured such that the cross-section of the limiting groove is V-shaped.

[0013] With further design, the V-shaped limiting groove allows the bar stock to move and be limited by its own weight towards the center of the limiting groove. Combined with the upper abutment part, it can reliably position bars of different diameters and prevent slippage and displacement.

[0014] This utility model can be further configured such that the spacing between the guide and the two adjacent bases is consistent.

[0015] By further refining the design, the guide is spaced evenly with the two adjacent bases, forming uniformly distributed support points. This ensures balanced stress distribution across the slender bar stock, preventing bending deformation caused by uneven support and significantly improving processing stability.
