Description

Technical Field

[0001] The invention relates to the field of wood processing machinery, in particular to a turning and milling compound processing center. Background Art

[0002] For the processing of long wood, the raw material wooden column needs to be cut, and the wooden column is processed to the required thickness and then placed in the lathe for cutting according to the specified shape. Finally, the cut parts are uniformly polished. Such operations need to be processed by multiple processing machine tools. The processing steps are very cumbersome, the machine tools occupy a large area and the work efficiency is low, and conventional polishing machines often polish unevenly, resulting in a high defective rate.

The present invention makes the table leg processing more convenient by combining multiple processing procedures together, and the assembly line operation of the table leg can be realized through the control device, which saves manpower and reduces the size of the occupied site. The present invention can realize three-axis processing of wood through the three-axis linkage device and the cutter head group, making the wood processing method more diversified.

[0004] With the application of technology, we found that there are still some problems, such as slow processing speed. For parts that need rough processing, a simple end mill head cannot meet the processing speed requirements. Therefore, how to increase the speed of the processing machine while ensuring the processing accuracy has become a technical problem that needs to be solved in the existing technology. Summary of the invention

[0005] The purpose of the present invention is to provide a turning-milling compound machining center, which can improve the machining speed of rough machining, and at the same time achieve the effect of automated flow machining, thereby improving machining efficiency.

[0006] In order to solve the above problems, the present invention discloses a turning and milling compound machining center, comprising a workbench, a spindle box and a tailstock are arranged on the workbench, and a machining tool group is arranged at the rear of the workbench.

[0007] The spindle box is fixedly arranged on the workbench, and the tailstock coaxially arranged with the spindle box can move left and right along the tailstock track on the workbench;

[0008] The machining tool group moves along the tool group track relative to the X-axis of the machine tool through the tool group seat, and moves along the Y-axis guide rail relative to the Y-axis of the machine tool. A milling tool group is provided on one side of the tool group seat, and a three-axis linkage tool group is provided on the other side.

[0009] The milling and grinding tool group includes an end milling tool group and an end grinding tool group, and the end milling tool group and the end grinding tool group are respectively assembled through a Y-axis moving seat that can move forward and backward along the Y-axis of the machine tool and fixed on the tool group seat;

[0010] The three-axis linkage tool group includes a drill tool group and a saw tool group, and the drill tool group and the saw tool group are fixed on the tool group seat through a tool group pushing guide rail and a Z-axis moving assembly. The drill tool group and the saw tool group can independently move in the Y-axis direction of the machine tool through the tool group pushing guide rail, and the movement of the tool group pushing guide rail in the Z-axis direction of the machine tool is controlled through the Z-axis moving assembly. The three-axis synchronous movement of the three-axis linkage tool head is realized through the tool group track, the Y-axis guide rail and the Z-axis moving assembly.

[0011] Furthermore, the tool group propulsion guide rail includes a track plate, the drill tool group and the saw tool group are fixed and moved by the track plate, the track plate is driven by a motor to move on the vertical support plate, and the motor and the vertical support plate form a Z-axis moving assembly.

[0012] Furthermore, the saw blade assembly includes a wheel saw, and the wheel saw is driven by a wheel saw motor.

[0013] Furthermore, the drill bit set includes two drill bits.

[0014] Furthermore, a tool changing magazine is provided on the side of the workbench, and tool heads of different models are provided on the tool changing magazine.

[0015] Furthermore, an inclined blanking surface is provided at the lower part of the workbench, and a receiving trough is provided at the bottom end of the blanking surface.

[0016] Furthermore, a dust removal vent is provided at the rear end of the three-axis linkage knife group for discharging wood chips and dust.

[0017] Furthermore, an automatic feeding device is also provided on the side of the workbench.

[0018] The beneficial effects of the present invention are:

[0019] By setting a saw blade group on the three-axis linkage tool group, the wheel saw is driven by the wheel saw motor to saw the material driven by the spindle box and the tailstock. Since the material and the wheel saw rotate at the same time, the efficiency of the roughing process is greatly improved, and then the vertical milling machine is used for fine processing, which reduces the shortcoming of the traditional vertical milling machine for roughing that takes a long time. In addition, the setting of the tool changing magazine and the automatic loading device further improves the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
