[0033] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may also be a central element; when an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be a central element; the terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] See attached Figure 1-5 The utility model provides a tool cylinder for a CNC center disc tool magazine, comprising the following structure:

[0037] The connecting tube 1 has a plurality of bending pieces 2 fixedly disposed on the top thereof, and a deformation groove 21 fixedly disposed on the outer side of the bending piece 2.

[0038] The sleeve 3 has a butt-jointed inclined surface 31 fixedly disposed at the bottom of the inner wall of the sleeve 3 , and the butt-jointed inclined surface 31 extends to the outside of the bending piece 2 .

[0039] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, a base 5 is fixedly provided at the bottom of the connecting tube 1 , and an extension arm 51 is fixedly provided at the front of the base 5 .

[0040] The arrangement of the base 5 and the extension arm 51 completes the assembly and use of the product on a horizontal disc tool magazine.

[0041] In this embodiment, Figure 2 and Figure 3 As shown, a sealing seat 6 is threadedly connected to the middle of the bottom end of the base 5 , a supporting spring 61 is clamped on the top of the sealing seat 6 , and a plug 62 is fixed on the top of the supporting spring 61 .

[0042] The sealing seat 6 completes the sealing of the bottom of the connecting tube 1 to prevent the debris inside the tool magazine from mixing into the hole in the middle of the tool handle 7 through the bottom of the connecting tube 1. The setting of the support spring 61 ensures that the plug 62 is docked with the hole below the tool handle 7, further improving the support and anti-foreign matter protection of the tool handle 7 by the tool cylinder product. When maintaining the tool cylinder product, it is necessary to remove the sealing seat 6, the support spring 61 and the plug 62, and clean and maintain the inside of the connecting tube 1 and the sleeve 3.

[0043] In this embodiment, Figure 2 , Figure 4 and Figure 5 As shown, a limiting protrusion 22 is fixedly provided on the top of the bending piece 2.

[0044] The limiting protrusion 22 on the bending piece 2 cooperates with the anti-dropping protrusion 33 below the sleeve 3 to prevent the sleeve 3 from falling off the bending piece 2.

[0045] Due to the cooperation between the bending piece 2 and the deformation groove 21, when the tool handle 7 is pressed on the top of the sleeve 3, the limit spring 4 is compressed, and the docking slope 31 of the sleeve 3 contacts the outside of the bending piece 2. The bending piece 2 deforms axially toward the connecting tube 1, and the tool handle 7 is partially embraced by extending into the bending piece 2, thereby reducing the shaking of the tool handle 7 in the connecting tube 1 and improving the stability of the product carrying the tool handle 7 and rotating with the horizontal disc tool magazine.

[0046] In this embodiment, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a slot 32 is fixedly provided on the inner side of the sleeve 3, and the slot 32 cooperates with the limiting protrusion 22. An anti-slip protrusion 33 is fixedly provided on the bottom of the sleeve 3. The bottom of the sleeve 3 is clamped with a limiting spring 4, and the bottom of the limiting spring 4 is clamped with the outer side of the connecting tube 1.

[0047] The engagement groove 32 of the sleeve 3 cooperates with the limiting protrusion 22 to prevent the handle 7 from being too heavy and causing the sleeve 3 to over-express the bending piece 2, and serves as a limiting protection for the sleeve 3 to squeeze and deform the bending piece 2.

[0048] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the middle part of the sleeve 3 is sleeved with a tool handle 7, the middle part of the tool handle 7 is clamped with an ER collet 71, the bottom opening of the tool handle 7 abuts against the outer side of the plug 62, and the outer side of the tool handle 7 is clamped with the bending piece 2 toward the axis of the connecting tube 1.

[0049] The tool handle 7 and the ER collet 71 cooperate to meet the user's needs for installing a CNC center machining tool.

[0050] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
