Description

Technical Field

[0001] This utility model relates to the field of positioning sleeve technology, and more specifically, to a lower tool shaft positioning sleeve with a locking structure. Background Technology

[0002] The tool spool positioning sleeve with a snap-fit ​​structure plays an important role in machining equipment. Its design purpose is to improve the stability, accuracy, efficiency of tool installation and the convenience of equipment maintenance. Secondly, it forms a rigid connection with the tool spool through the snap-fit ​​structure.

[0003] In existing publicly available literature, patent publication number CN219404463U discloses a bushingless positioning device for a slitting master blade. This technology, through the action of a support rod, gives the rubber roller a certain rigidity, ensuring that it can limit the position of the bushingless paper tube. Simultaneously, under the action of the limiting rod and the compression spring, the sliding trajectory of the support rod and the rubber roller is restricted. The compression spring also applies a downward force to the rubber roller, ensuring that the rubber roller can smoothly restrict the position of the bushingless paper tube, thereby effectively increasing the positioning accuracy of the bushingless paper tube and improving the precision of subsequent cutting. However, this patent has the following drawbacks.

[0004] When positioning and installing a tool, the tool shaft positioning sleeve has multiple engagement points, making it difficult to achieve synchronous positioning and installation of the tool and the positioning sleeve at multiple points. This results in a slow positioning and installation speed and makes it difficult to achieve efficient synchronous positioning and installation. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1-5 The diagram shows a lower tool shaft positioning sleeve with a locking structure. The lower tool shaft positioning sleeve with a locking structure is provided with a synchronous positioning component. The synchronous positioning component enables the tool and the positioning sleeve to be synchronously positioned and installed at multiple points, achieving efficient synchronous positioning and installation. The specific structural configuration of the synchronous positioning component is as follows.

[0021] In this technical solution, as shown in the appendix Figure 1 - Appendix Figure 4 As shown, a guide ring 2 is installed on the outside of the cutter shaft sleeve 1.

The vertical cross-sectional shape of the guide ring 2 is annular.

[0022] In this technical solution, as shown in the appendix Figure 1 - Appendix Figure 3 As shown, a sliding sleeve 9 is fixedly connected to one end of the magnet 8, and a guide rod 10 is slidably connected to the inner wall of the sliding sleeve 9, so that the magnet 8 can drive the sliding sleeve 9 to press and move, and the sliding sleeve 9 can press and move along the outer wall of the guide rod 10. The guide rod 10 is fixedly connected to the cutter shaft sleeve 1. One end of the cutter shaft sleeve 1 is fixedly connected to a connecting sleeve 11, and one end of the mating sleeve 12 is fixedly connected to a shrinking sleeve 13, so that the lower cutter shaft can be inserted into the cutter shaft sleeve 1, and simultaneously enter the mating sleeve 12 through the connecting sleeve 11, and then enter the shrinking sleeve 13 through the mating sleeve 12, realizing the insertion and installation operation. A sliding strip 14 is fixedly connected to the top of the inner wall of the guide pressure ring 2, and a guide frame 15 is slidably connected to the outer wall of the sliding strip 14. The guide frame 15 is fixedly connected to the cutter shaft sleeve 1. The outer wall of the slider 14 and the inner wall of the guide frame 15 are both smooth surfaces.
