Description

Technical Field

[0001] This utility model relates to the field of connecting rod processing technology, and in particular to a precision milling processing device for connecting rods. Background Technology

[0002] As a key transmission component in equipment such as engines and compressors, the machining accuracy of connecting rods directly affects the performance and lifespan of the equipment. Precision milling is one of the core processes in connecting rod machining, which requires a balance between efficiency and precision.

[0003] Existing precision milling equipment for connecting rods has a relatively simple structure, making it difficult to adapt to multiple specifications of connecting rods. It also suffers from insufficient clamping stability, limited movement and positioning accuracy of the milling mechanism, frequent tool changes that affect machining accuracy, slow process connection, asynchronous loading and unloading and machining, low production efficiency, and difficulty in meeting the needs of mass production.

[0004] Therefore, in order to address the problems of existing precision milling machines for connecting rods being unable to adapt to multiple specifications of connecting rods and having low machining accuracy and efficiency, a precision milling machine for connecting rods can be designed. Utility Model Content

[0005] To overcome the problems of existing precision milling equipment for connecting rods being unable to adapt to multiple specifications of connecting rods, resulting in low machining accuracy and efficiency.

[0006] The technical solution of this utility model is as follows: a precision milling device for connecting rods, including a base; it also includes a rotating seat and a clamping plate. A support frame is fixedly connected to the upper end of the base, and a partition block is fixedly connected to the middle of the lower end of the support frame. A lead screw is rotatably connected to both ends of the inner wall of the support frame and the partition block. A movable seat is threadedly connected to the outer side of the lead screw. A milling cutter shank is provided at the lower end of the movable seat. A worktable is provided at the upper end of the base. Two rotating seats are rotatably connected to the upper end of the worktable. An adjustment cavity is opened at the upper end of each rotating seat. A bidirectional threaded rod is rotatably connected inside the adjustment cavity. A clamping plate is threadedly connected to both ends of the outer side of the bidirectional threaded rod.

[0007] Preferably, the milling cutter holders of the two milling stations are pre-loaded with milling cutters of different specifications. The connecting rod to be machined is placed on the rotating seat. The rotation of the bidirectional threaded rod drives the clamping plate to make relative movements and move the same distance, clamping the connecting rod to complete the loading. The rotation of the lead screw drives the moving seat to move precisely along the preset path. At the same time, the rotating seat rotates to adjust the angle of the connecting rod. After one milling station completes rough milling, the worktable rotates 180° to exchange stations, and the other milling station immediately performs finish milling. The two stations handle the process separately.

[0008] Preferably, a movable motor is fixedly connected to both the left and right ends of the support frame, and the output shaft of the movable motor is fixedly connected to the corresponding lead screw. The movable motor is used to drive the lead screw to rotate.

[0009] Preferably, a lifting cylinder is fixedly connected to the lower end of the movable seat, and a lifting base is fixedly connected to the output end of the lifting cylinder. The lifting cylinder is used to drive the lifting base to move up and down, and the rear end of the lifting base is slidably connected to the movable seat.

[0010] Preferably, a milling motor is fixedly connected inside the lifting base. The output shaft of the milling motor extends to the lower end of the lifting base and is fixedly connected to the milling cutter holder. The milling motor is used to drive the milling cutter holder to rotate.

[0011] Preferably, a tilting motor is fixedly connected to the upper end of the base, and the output shaft of the tilting motor is fixedly connected to the lower end of the worktable. The tilting motor is used to drive the worktable to rotate.

[0012] Preferably, two rotary motors are fixedly connected to the lower end of the worktable. The output shafts of the rotary motors extend to the upper side of the worktable and are fixedly connected to the rotating base. The rotary motors are used to drive the rotating base to rotate.

[0013] Preferably, an adjusting motor is fixedly connected to the outside of the rotating seat, and the output shaft of the adjusting motor is fixedly connected to the bidirectional threaded rod. The adjusting motor is used to drive the bidirectional threaded rod to rotate, and rubber pads are fixedly connected to the clamping surfaces of the clamping plates.

[0014] The beneficial effects of this utility model are:

[0015] This precision milling device for connecting rods utilizes a rotating base and a clamping plate. The milling cutter holders at two milling stations are pre-loaded with milling cutters of different specifications. The connecting rod to be machined is placed on the rotating base, and the rotation of the bidirectional threaded rod drives the clamping plate to move relative to it, traveling the same distance to clamp the connecting rod and complete the loading process. It is compatible with various connecting rod specifications, offering high clamping stability. The rotation of the lead screw drives the moving base to move precisely along a preset path, while the rotating base rotates to adjust the connecting rod angle. Combined with the milling cutter, this allows for multi-angle, comprehensive machining of the connecting rod with high positioning accuracy. After rough milling at one milling station, the worktable rotates 180° to exchange stations, and the other milling station immediately performs finish milling. This dual-station division of labor eliminates positioning errors caused by frequent tool changes, improving machining accuracy, stability, and process connection efficiency. The two rotating bases alternately for loading, unloading, and machining, and the station exchanges enable continuous production. This high degree of automation improves machining efficiency and meets the high-precision requirements of mass production. Attached Figure Description
