Description

Technical Field

[0001] This utility model relates to the field of threaded sleeve machine technology, and in particular discloses a cutting tool assembly for a threaded sleeve machine. Background Technology

[0002] Screw sleeve machines, commonly known as spring machines, generally refer to mechanical equipment used to produce springs. Based on their functional characteristics, they are classified as: compression spring machines, extension spring machines, universal machines, disc spring machines, and specialized spring machines such as serpentine spring machines and torsion spring machines. Based on their drive method, they are classified as: semi-automatic, automatic, and CNC.

[0003] In spring processing machines, cam mechanisms are used to drive the corresponding cutting tools. However, in practical applications, the stroke of the cutting tools is generally short. Therefore, existing cam drive mechanisms are generally driven by telescopic motors. However, the reciprocating drive of the cutting tools by the telescopic motor will produce a large error after a certain cumulative stroke, which will affect the stability of spring processing. At the same time, existing cam drive mechanisms have problems with installation and debugging. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a tool assembly that is easy to install, easy to debug, and has high machining accuracy.

[0005] To achieve the above objectives, this utility model provides a tool assembly for a threaded sleeve machine, comprising a tool base and a drive assembly. An external tool is mounted on the tool base, and the drive assembly drives the tool base. The drive assembly drives the tool base to move, thereby moving the tool closer to or away from the workpiece. The drive assembly includes a slide groove, a slide rail that mates with the slide groove, and a drive component. The tool base is mounted on the slide rail, which is driven by the drive component. The slide rail is slidably connected to the slide groove via the drive component. This utility model uses the slide groove, slide rail, and drive component to move the tool base, making the entire assembly easy to install and adjust, improving machining accuracy, and avoiding machining errors caused by telescopic motor drives.

[0006] Furthermore, the tool base includes a tool mounting seat and a tool holder. The tool mounting seat has a through hole, and the tool mounting seat is sleeved on the tool holder through the through hole. The tool holder is connected to the slide rail, and the tool mounting seat and the tool holder are connected by bolts.

[0014] Furthermore, the tool assembly comprises multiple sets, which are arranged in a circular array around the central axis of the external workpiece. This circular array arrangement of multiple tool assemblies enables simultaneous multi-directional machining of the workpiece, improving machining efficiency and achieving omnidirectional machining of the workpiece.

[0015] The beneficial effects of this utility model are as follows: This utility model uses a sliding groove, a sliding rail and a driving component to move the tool base, making it easy to install and debug, improving machining accuracy and avoiding machining errors caused by the telescopic motor drive.

[0016] The tool mounting seat can be adjusted along the length of the tool holder by the cooperation of the first mounting hole and multiple sets of second mounting holes, which improves the flexibility of the tool mounting position, adapts to different processing needs, and facilitates fine adjustment of the tool position, further improving the processing accuracy.

[0017] By using the third and fourth mounting holes, bolts are used to fix the tool holder and slide rail, which improves the stability and reliability of the connection between the tool holder and slide rail. At the same time, it is easy to disassemble and adjust the position of the slide rail, which improves the convenience of maintenance and debugging.
