Tool magazine, tool changing mechanism and multi-spindle machining center

Abstract

The invention provides a tool magazine, a tool changing mechanism with the tool magazine and a multi-spindle machining center comprising the tool changing mechanism. The tool magazine comprises a toolmagazine mounting bracket, a tool magazine bracket and multiple tool storage bins. The tool magazine mounting bracket is configured to be fixed to a machine tool spindle beam. The tool magazine bracket is mounted on the tool magazine mounting bracket. The tool storage bins are fixed to the tool magazine bracket. Each of the tool storage bins comprises multiple tool storage cavities and is characterized in that the tool storage cavities in each of the tool storage bins are formed into a tool storage cavity matrix; and the tool storage cavities formed in the direction parallel to the machine tool spindle beam form a row of the tool storage cavity matrix, and the number of rows of the tool storage cavity matrixes is larger than 1. The tool magazine has large tool storage capacity, good toolprotection and long maintenance period, the tool changing efficiency of the tool changing mechanism using the tool magazine is high, and the machining efficiency of the machining center is high.

Description

technical field [0001] The invention relates to a tool changing mechanism of a machining center, in particular to a tool changing mechanism of a multi-spindle machining center. Background technique [0002] Since the processing efficiency of multi-spindle machining centers (referred to as multi-head machining centers or multi-head machine tools) is several times or even dozens of times higher than that of single-spindle machining centers (referred to as single-head machining centers or single-head machine tools), the application of multi-head machining centers has increased this year. The more widely, especially in the 3C industry, the multi-head machining center is widely used; however, while the multi-head machining center has the advantages of efficient processing, the tool change process involving the tool library has become a major factor that limits the further improvement of its processing efficiency. [0003] At present, the tool magazine of multi-head machine tools ...

Problems solved by technology

[0005] (2) The tool holder 11.1 is in the form of a caliper, that is, there is a relatively close pre-tightening force between the two jaws of the tool holder 11.1. The above-mentioned pre-tightening force will open the tool holder, so the tool handle will be worn to a certain extent during the spindle tool change process;

[0006] (3) Although the installation position of the tool magazine 11 is far away from the main shaft to avoid the influence of processing dust, etc., and in similar applications, the tools clamped in the tool magazine 11 can be protected from the pollution environment by setting the tool magazine door, but the main shaft When changing the tool, it is still necessary to move the tool magazine forward (to the direction of the spindle, that is, Figure 23 In the middle Y direction), that is, in the process of tool change, it is still unavoidable that the handle of the tool is contaminated, and the handle of the tool is contaminated, which will further cause damage to the spindle where it is clamped;

[0007] (4) When the tool change process starts, the spindle needs to stop processing, then put the original tool on the spindle back into the tool magazine 11, and then select a new tool from the tool magazine 11 to clamp it on the spindle. The tool magazine 11 does not have the ability to prepare tools in advance function, low tool change efficiency;

[0008] (5) The tool capacity of the tool magazine 11 is small, and the tool handle is easy to wear, and the two factors work together to cause the tool replacement frequency of the entire tool magazine 11 to be high, the maintenance cycle is short, waste time and labor, and affect the overall production efficiency
