Description

Technical Field

[0001] The utility model relates to the technical field of ball screw assembly, in particular to a sliding type heavy-duty ball screw butt joint splicing processing tool. Background Art

[0002] The ball screw is an important component of the screw nut mechanism, which is mainly reflected in the equal pitch structure of the screw and can stably convey the nut. In existing equipment, for small and medium-sized screw nut mechanisms, a suitable ball screw can be used to complete the assembly, but for equipment with high stability requirements and large loads, heavy ball screws are required to drive the nut to convey torque.

[0003] Compared with small ball screws, heavy-duty ball screws have larger diameters and heavier weights. During processing, in order to cooperate with machine tools, segmented processing has to be adopted, that is, the processing is divided into sections, and then the processed screws are connected. During segmented processing, the two ends of the screw have adopted male and female heads for easy assembly.

[0004] However, the current assembly mostly relies on manual labor. Although the assembly can be normal, if there is a gap after assembly, damage will occur in the transmission torque, resulting in the breakage of the ball screw. In order to ensure the overall performance of the ball screw after docking and assembly, it is necessary to ensure that the pitch size on the screw is the same after assembly, and the ball can slide smoothly through the thread groove. Based on the inconvenience of installation in the prior art and the inability to maintain the safety and stability of the heavy ball screw assembly process, a sliding heavy-duty ball screw docking and splicing processing tool is proposed.

[0008] In the above scheme, the guide rail includes a first linear guide rail assembly and a second linear guide rail assembly, the first linear guide rail assembly and the second linear guide rail assembly are arranged in parallel, and the bottom two sides of the support device are fixedly connected to the first linear guide rail assembly and the second linear guide rail assembly respectively.

[0009] Among them, as a preferred solution, a positioning bar is installed between the first linear guide assembly and the second linear guide assembly, and the positioning bar is fixed to the middle of the workbench of the main frame. The positioning bar is an inverted U-shaped structure, and a weight-reducing groove is opened on the top.

The two sides of the bottom of the support device 3 are respectively fixedly connected to the first linear guide assembly 21 and the second linear guide assembly 22, and linear sliding is performed with the help of the sliding function of the guide rail 2.

[0026] As a preferred solution, a positioning bar 23 is installed between the first linear guide assembly 21 and the second linear guide assembly 22.
