Description

Technical Field

[0001] The invention relates to the technical field of precision engraving machines, and in particular to a multi-head precision engraving machine and a rotary tool magazine thereof. Background Art

[0002] Precision engraving machines are widely used in the processing of precision parts, especially small and complex-shaped workpieces. Existing precision engraving machines usually rely on manual tool change during tool change. This method is not only inefficient, but can only process one workpiece at a time, and it takes a lot of time and effort to change the tool. In order to improve efficiency, some precision engraving machines are equipped with automatic tool magazines, but most tool magazines adopt a straight-row design, suspended under the beam, and usually only have a single row of tool storage. This type of tool magazine has a slow tool change speed, poor stability, a limited number of tools that can be accommodated, and unstable tool change action. Summary of the invention

[0003] 1. Problems to be solved

[0004] The technical problem to be solved by the present invention is to provide a multi-head precision engraving machine and a rotary tool magazine thereof in view of the current status of the prior art.

[0005] (II) Technical solution

[0006] The present invention is achieved through the following technical solutions:

[0007] A multi-head engraving machine and a rotary tool magazine thereof, comprising a rotary drum tool magazine and a tool magazine driving device. The rotary drum tool magazine is provided with a plurality of slot arrays arranged along the axial direction of the rotary drum tool magazine, the slot arrays comprising a plurality of inserting knife units evenly distributed on the outer circumference of the drum, the inserting knife units comprising a knife holder installed on one side of the slots. The tool magazine driving device comprises a rotating shaft connected to the two end surfaces of the rotary drum tool magazine. The rotating shaft is provided with a driving motor, the driving motor is used to drive the rotating shaft to rotate, and then drive the rotary drum tool magazine to rotate.

[0008] By adopting the above technical solution, the tool to be used is placed in the tool holder. When changing the tool, it is only necessary to move the rotary tool magazine forward and backward for a certain distance, and then rotate the rotary tool magazine to cooperate with the multi-head processing module to complete the tool change action. The rotary tool magazine is cleverly designed and flexible to use. It can hold different types of tools to meet production needs.

[0009] Furthermore, the driving motor is connected to a reducer, and the reducer is equipped with a first gear. The first gear is transmission-connected with a second gear, and the second gear is installed at one end of the rotating shaft, and the rotating shaft sleeve is provided with a bearing.

[0010] Furthermore, the bearing is embedded in the roller support seat, and the roller support seat is connected to the tool magazine bottom plate. The tool magazine bottom plate is connected to a flush block bracket, and the flush block bracket includes a plurality of hollow surfaces. A tool magazine sensing bracket is installed on the flush block bracket, and the tool magazine sensing bracket is installed with a plurality of sensors arranged and distributed along the rotation axis direction.

[0011] A multi-head precision engraving machine comprises a bed, a double-moving sliding module, a workbench, a multi-head processing module and a rotary tool magazine. The workbench and the tool magazine bottom plate are respectively mounted on the first moving sub-sliding block and the second moving sub-sliding block of the double-moving sliding module. The double-moving sliding module is mounted on the bed. The multi-head processing module is mounted above the double-moving sliding module.

[0012] By adopting the above technical solution, when the engraving machine needs to replace the tool for the next processing operation, the double-actuator sliding module drives the workbench to stop at the working end, and drives the rotary drum tool magazine to the bottom of the multi-head processing module. Then the left and right movement of the multi-head processing module aligns the processing shaft with the gripping port of the fixture below, and drives the processing shaft up and down through the lifting and lowering movement of the lifting mounting plate. After the processing shaft puts the unused tool into the tool holder, the tool magazine drive device drives the rotary drum tool magazine to rotate so that the tool to be used is in the corresponding position of the fixture gripping port. Finally, the processing shaft grabs the tool and completes the replacement. The device has a fast tool change speed and a high degree of automation. In addition, it can process multiple parts at a time, with high production efficiency.

[0013] Furthermore, a rear baffle and a tool setting instrument are installed in connection with the workbench, and the rear baffle is used to isolate the tool setting instrument from the working space above the workbench.

[0014] Furthermore, the bed is mounted on a base. The bed is provided with a plurality of supporting columns which are relatively placed, and supporting beams are installed and connected between the supporting columns.

[0015] Furthermore, the supporting crossbeam is installed with an x-axis guide rail and a drag chain box, and the multi-head processing module is slidably installed on the x-axis guide rail through an x-axis slider.

[0016] Furthermore, the multi-head processing module includes a lifting plate, a z-axis guide rail is installed on the lifting plate, and a z-axis slider is arranged on the z-axis guide rail. A plurality of processing head devices are slidably installed on the z-axis guide rail through the z-axis slider.

[0017] Furthermore, the processing head device includes a rotating shaft mounting frame and a processing rotating shaft installed in the rotating shaft mounting frame and capable of automatically grabbing a tool.

[0018] Furthermore, a dust cover is arranged outside the rotary tool magazine, and a plurality of clamp grabbing openings are opened on the outer dust cover.

[0019] (III) Beneficial effects

[0020] The present invention is designed with a rotatable tool magazine, which can replace the tool holder array by rotating it with a driving motor, thus simplifying the tool changing process. The tool part is in the cylindrical tool magazine drum, and the tool magazine has high space utilization and large capacity, which can meet the tool loading needs of multiple processing axes. In addition, by reasonably designing the tool setting structure behind the workbench, the position of the newly installed tool will be detected and compensated every time the tool is changed, thereby improving the processing accuracy of the precision engraving machine. The multi-head precision engraving machine equipped with a rotatable tool magazine has the advantages of stable and reliable operation, good processing quality, high efficiency, simple operation and convenient maintenance.
