Description

Technical Field

[0001] This utility model relates to the field of CNC equipment and CNC machining technology, and in particular to a tool magazine position adjustment device for a five-axis machining center. Background Technology

[0002] In modern manufacturing, CNC machine tools are key equipment for achieving high-precision and high-efficiency machining, and their performance directly affects product quality and production efficiency. The tool magazine, as one of the core components of a CNC machine tool, undertakes the important task of storing and quickly changing tools. The performance of the tool magazine position adjustment device plays a decisive role in the operation of the tool magazine and even the entire CNC machine tool.

[0003] Chinese Patent 201420586717.4 discloses a miniature multi-functional composite machining center, including a tool magazine, a CNC system, two spindles, three-degree-of-freedom feed axes, and two-degree-of-freedom rotary axes. The tool magazine is mounted on the front of the machine tool, at the highest point directly in front of the spindle head, and its automatic tool changing device robotic arm is longitudinally arranged on the right side of the machine tool. The CNC system is mounted on the right side of the machine tool and connected by two linkage mechanisms, allowing free movement within the range of motion of the linkage mechanisms. A locking handle can be used to lock the mechanism, fixing the position of the CNC system. The three-degree-of-freedom feed axes are X-axis, Y-axis, and Z-axis; the two-degree-of-freedom rotary axes are A-axis and B-axis. The A-axis is also used as a turning spindle and can be removed to increase the effective travel of the worktable and the machine tool's X-axis. This machine tool is characterized by its small size, light weight, and ability to be placed anywhere, even in buildings; it has low power consumption and can be powered directly by lighting power; it has extremely rich functions, a flexible and controllable structure, includes a tool magazine, can automatically change tools, can achieve five-axis linkage, and can complete machining processes such as turning, milling, boring, planing, grinding, planing, drilling, tapping, and gear hobbing.

[0004] However, this technical solution integrates the machine tool and tool magazine into one unit, which does not allow for flexible adjustment of the relative positions of the machine tool bed and tool magazine. Furthermore, the operation of the tool magazine may affect the operation of the machine tool and the production of other critical components, thus interfering with normal production operations. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a tool magazine position adjustment device for a five-axis machining center. By adopting a split installation layout, specifically by connecting the machine tool and the tool magazine through a multi-link mechanism to form a split installation, the spatial layout is more flexible, and the relative position of the machine tool and the tool magazine can be adjusted and is more stable.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tool magazine position adjustment device for a five-axis machining center, comprising:

[0008] Connecting components are respectively installed on the side where the machine tool bed and the tool magazine base are connected;

[0009] A multi-link mechanism, which is mounted on the connector and connects the machine tool bed and the tool magazine base;

[0010] And a joint assembly, which is installed at the connection between the connector and the multi-link mechanism.

[0011] As an improvement, the joint assembly is a joint bearing.

[0012] As an improvement, the spherical bearing is used at the connection between the connector and the multi-link mechanism.

[0013] As an improvement, the multi-link mechanism includes: a first link, a second link, and a third link, wherein the first link is parallel to the second link and its two ends are respectively connected to the connecting parts of the machine tool bed and the tool magazine base, and the third link is obliquely installed on the diagonal line between the first link and the second link, and its two ends are respectively connected to the connecting parts of the machine tool bed and the tool magazine base.

[0014] As an improvement, the first link, the second link, and the third link are connected at the connecting member by a spherical bearing to form a movable system.

[0015] As an improvement, the first link, the second link, and the third link are connected in the multi-link mechanism to form two triangular structures.

[0016] As an improvement, the machine tool and tool magazine are connected by a multi-link mechanism to form a separate installation.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) This utility model adopts a split installation, specifically by connecting the machine tool and the tool magazine through a multi-link mechanism to form a split installation. It can flexibly adjust the relative position of the tool magazine and the machine tool bed according to the space conditions of the production workshop. It is especially suitable for workshops with limited space or special layout requirements, which facilitates the placement of equipment and the planning of logistics channels.

[0019] (2) When the tool magazine in this utility model is working, since it is separated from the bed, it will not affect the operation of the machine tool and the production of other key components too much, thereby improving the machining accuracy of the machine tool and thus improving the production efficiency and quality of industrial operations;

[0020] (3) The multi-link mechanism of this utility model can transform the motion of a single power source into the composite motion of the tool magazine through the length ratio design of the link and the rotational coordination of the joint bearing, thereby meeting the multi-dimensional position adjustment requirements and ensuring that the tool can be accurately aligned with the spindle tool change position.

[0027] Example 1

[0028] like Figure 1 , 2 As shown, this utility model provides a tool magazine position adjustment device for a five-axis machining center, comprising:

[0029] Connector 1, wherein there are multiple connectors 1 and they are respectively installed on the side where the machine tool bed and the tool magazine base are connected, so as to facilitate the connection of the multi-link mechanism 2 and the joint assembly 3 between the machine tool bed and the tool magazine base;

[0030] A multi-link mechanism 2 includes a first link 21, a second link 22, and a third link 23. The first link 21 is parallel to the second link 22, and both ends are connected to the connecting member 1 of the machine tool bed and the tool magazine base, respectively. The third link 23 is obliquely installed on the diagonal line between the first link 21 and the second link 22, and both ends are connected to the connecting member 1 of the machine tool bed and the tool magazine base, respectively. The multi-link mechanism 2 is installed on the connecting member 1 and is used to connect the machine tool bed and the tool magazine base.

[0031] And joint assembly 3, which is a joint bearing 31, is installed at the connection between the connector 1 and the multi-link mechanism 2 to ensure the stability, motion accuracy and load-bearing capacity of the joint connection; wherein, the joint bearing 31 adopts a spherical hinge at the connection, which can rotate at multiple angles to quickly adapt to the position of the main shaft while ensuring the compactness of the multi-link mechanism 2.

[0032] It is worth noting that the machine tool and tool magazine are adjusted by adjusting the length of the connecting rod of the spherical bearing 31 and the multi-link mechanism 2, so that the position of the tool magazine relative to the machine tool bed can be adjusted.

[0033] Preferably, the first link 21, the second link 22, and the third link 23 are connected at the connector 1 by a spherical bearing 31 to form a movable system. The spherical bearing 31 allows adjacent links to rotate relative to each other around a fixed axis, realizing multi-degree-of-freedom motion and improving the flexibility and convenience of tool magazine position adjustment. The parameters of the spherical bearing 31 (such as wheelbase and rotation angle range) can be predetermined by mechanical design, improving the accuracy of tool magazine position during adjustment, facilitating precise positioning during tool changing, and achieving high-precision adjustment.

[0034] Preferably, the first link 21, the second link 22, and the third link 23 are connected in the multi-link mechanism 2 to form two triangular structures. The first link 21, the third link 23, and the connector 1 form a triangular structure, and the second link 22, the third link 23, and the connector 1 also form a triangular structure. This makes the connection structure compact, and the triangular structure can ensure the stability of the connection between the machine tool bed and the tool magazine base, thus improving the safety of the tool magazine during operation.

[0035] Example 2

[0036] like Figure 2 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0037] In this embodiment, the machine tool and tool magazine are connected by a multi-link mechanism 2 to form a separate installation. The relative positions of the machine tool and tool magazine can be flexibly adjusted according to the space conditions of the production workshop, which is especially suitable for workshops with limited space or special layout requirements. Since the machine tool and tool magazine are separate, it will not affect the operation of the machine tool and the production of other key components, thereby improving the machining accuracy of the machine tool and thus improving the production efficiency and quality of industrial operations. In later production, if it is necessary to increase the tool magazine capacity or replace it with a different type of tool magazine, there is no need to carry out large-scale modifications to the machine tool bed, which facilitates the expansion of production operations.

[0038] Working principle

[0039] (1) The multi-link mechanism 2 is a movable structure consisting of three rigid links connected by a lower pair (such as a joint bearing 31). Its working principle is to convert the input motion of the active link into the expected output motion of the driven link through the orderly motion transmission and conversion between the links.

[0040] (2) From the perspective of motion transmission, there is usually one active member in the mechanism, whose motion is transmitted to the driven member in sequence through the hinge points of adjacent links. Since the length of each link is fixed and the motion freedom of the hinge points is constrained (such as the joint bearing 31, which is only allowed to rotate around the axis), the motion trajectory of the entire mechanism is strictly limited to the design range.

[0041] (3) From the perspective of constraint and coordination, the lower pair connection ensures that the relative motion between the links is only carried out in the preset direction, avoiding motion chaos caused by redundant degrees of freedom. At the same time, the length ratio of each link and the position of the hinge point directly determine the motion characteristics of the mechanism. The structural characteristics of the rigid link ensure the effective transmission of force. When bearing load, the force is distributed to each link through the hinge point, so that the mechanism can complete the work under the premise of meeting the strength requirements.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
