Description

Technical Field

[0001] The utility model relates to auxiliary equipment of a numerical control machine tool, in particular to a numerical control tool storage device. Background Art

[0002] The tools used by CNC machine tools (hereinafter referred to as CNC tools) are stored in tool magazines in most cases. CNC machine tools automatically change tools from the tool magazines (this type of CNC machine tool with a tool magazine is called a machining center). If the number of tools in the tool magazine is full or the CNC machine tool is not equipped with a tool magazine, the tools need to have another storage device. This storage device is often installed on the machine tool workbench to facilitate tool storage and retrieval, but the existing tool storage device has the risk of tools falling off when the workbench moves.

[0003] The publication (announcement) number CN202878024U discloses a JT50 tool holder external storage tool holder, whose countersunk hole is only semicircular and the opening is larger than the circumferential diameter of the tool. The tool can move along the opening direction and the translation is controlled only by the force of the spring. When the workbench moves faster, the inertia force of the tool may be greater than the restraining force of the spring, and there is a risk of the tool falling off from the U-shaped opening. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a storage device for CNC tools.

[0005] The utility model adopts the following technical solutions to achieve the above purpose:

[0006] A storage device for numerical control tools, wherein the support of the storage device is a flat plate structure; the support is provided with a U-shaped opening for the numerical control tool to enter; the outer circle of the U-shaped opening is provided with an arc groove coaxially arranged with the U-shaped opening, and the bottom surface of the arc groove constitutes a supporting surface for supporting the numerical control tool; the support is also provided with a groove for placing a positioning key, and the groove is connected with the arc groove and protrudes from the arc groove.

[0007] The circumferential angle of the arc groove is greater than 180°.

[0008] The utility model provides a storage device for numerically controlled tools. The device adopts the above technical solution to store tools. When the device is installed in a machine tool, the tools can be stored and retrieved not only manually but also automatically by the machine tool. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is described in detail with reference to the accompanying drawings and specific embodiments:

[0016] like Figure 1 , Figure 2 As shown, a storage device for CNC tools, combined with Figure 3 , Figure 4 The bracket 1 of the storage device is a flat plate structure; the bracket 1 has a U-shaped opening 1-1 for the CNC tool to enter; the outer circle of the U-shaped opening 1-1 has an arc groove 1-2 coaxially arranged with the U-shaped opening, and the bottom surface of the arc groove 1-2 constitutes a supporting surface for supporting the CNC tool; the circumferential angle of the arc groove is greater than 180°; the inner wall surface of the arc groove is used to limit the center position of the tool, and the bracket is also provided with a groove 1-3 for placing a positioning key, and the positioning key is used to limit the circumferential angle position of the tool; the groove is connected with the arc groove and protrudes from the arc groove; the center line of the groove for placing the positioning key and the center line of the U-shaped opening may not be in the same straight line.

[0017] When the tool is placed in the storage device as shown in FIG5 , the tool is placed in the countersunk hole of the storage device bracket (1), the bottom surface of the countersunk hole supports the tool, the circumference of the countersunk hole limits the center of the tool so that the tool cannot move horizontally, and the key 2 is stuck in the keyway of the tool so that the tool cannot rotate.

[0018] The circumferential angle of the countersink of this device is greater than a semicircle (greater than 180°), the countersink opening is smaller than the circumferential diameter of the tool, the tool is rigidly fixed in the horizontal direction, the tool is deposited into the countersink from just above the countersink support surface, and the tool is taken out by lifting it, so there is no restriction on the circumferential position of the key (i.e. the angle α), which can be arbitrarily determined according to the direction of the machine tool spindle positioning key.

Claims
