Description

Technical Field

[0001] The utility model relates to the technical field of six-sided numerical control drilling, in particular to a compact six-sided numerical control drilling device with two lower spindles. Background Art

[0002] The current mainstream CNC six-sided drilling equipment can complete six-sided drilling at high speed, and most of the drilling processes for panel furniture can be completed with one clamping. However, the processing efficiency of plate grooving is still low, especially the back grooving of the plate; limited by the structure of the six-sided CNC drilling center, its bottom space is often extremely limited, resulting in the lower drilling head being unable to meet a wider range of processing sizes, and the lower drilling head still uses a single manual tool change spindle configuration, which greatly limits the improvement of the back grooving efficiency.

[0003] According to different furniture design requirements, the back of the panel usually needs to be processed into a 6mm, 10mm or even 19mm square groove for installing the cabinet back panel. In order to meet the milling requirements of various specifications, a single manual tool change spindle can only be installed with a minimum specification milling cutter. At this time, if a larger size back panel groove needs to be processed, multiple millings are required, or the machine needs to be stopped to manually change the tool of the appropriate specification, which seriously affects the efficiency of the groove processing on the back of the panel.

[0004] Especially in recent years, the popular one-door-to-ceiling design style has a maximum size of 2.8 meters for wardrobe door panels. After processing, the cabinet door will often bend and deform to a certain extent, resulting in poor installation effect. Therefore, it is generally necessary to process a straightener installation groove on the back of the panel and use a straightener to straighten the cabinet door. At present, CNC six-sided drilling equipment equipped with a single manual tool change spindle cannot simultaneously process the back panel groove (square groove) and the straightener groove (open cylindrical molding groove) without changing the tool. Usually, the straightener groove needs to be manually replaced with a tool for secondary clamping or processed on a special milling equipment, which requires transportation and secondary clamping. Not only is the efficiency low, but the accuracy is also difficult to guarantee. Utility Model Content

[0035] The six-sided CNC drilling device of the embodiment of the utility model has the following advantages:

[0036] 1) In the six-sided CNC drilling equipment, the lifting and lowering of two manual tool-changing spindles 3-4 are independently controlled by two lifting cylinders 3-6. The two spindles can be used separately. The two spindles can clamp milling cutters of different types and specifications at the same time, thereby improving the efficiency of plate grooving and reducing the number of manual tool changes. The processing of the back panel groove and the door panel straightener groove can be taken into account at the same time, reducing the number of panel clamping and panel transfer times in door panel processing, improving processing accuracy and efficiency, and saving production costs.

[0037] 2) In the six-sided CNC drilling equipment, the lower drilling head 3 is installed on the head transverse guide rail 2-1 on the side of the lower drilling support beam 2 through the head transverse slide 3-1, and the spindle base plate 3-2 of the lower drilling head 3 is located on the side of the head transverse slide 3-1 facing away from the lower drilling support beam 2. The two manual tool-changing spindles 3-4 and two lifting cylinders 3-6 of the lower drilling head 3 are respectively staggered on the front and rear sides of the spindle base plate 3-2 (i.e., the side facing the head transverse slide 3-1 and the side facing away from the head transverse slide 3-1). Therefore, the lower drilling support beam 2, the head transverse slide 3-1, the lifting cylinder 3-6, the spindle base plate 3-2, and the manual tool-changing spindle 3-4 are basically arranged along the direction of the gripper transverse guide rail, which greatly compresses the structural dimensions of the lower drilling head 3 in the direction of the head transverse guide rail, making the structural design of the lower drilling head 3 more compact and able to meet a wider range of processing dimensions.

[0038] 3) In the six-sided CNC drilling equipment, the base plate lifting motor 3-13 and the lifting screw pair 3-15 of the lower drilling head 3 are located on the side of the spindle base plate 3-2 facing the head transverse sliding slide 3-1, and the drill package 3-14 is located on the side of the spindle base plate 3-2 facing away from the head transverse sliding slide 3-1, forming a front-to-back staggered arrangement, which further compresses the structural dimensions of the lower drilling head 3 in the direction of the head transverse guide rail, making the structural design of the lower drilling head 3 more compact and able to meet a wider range of processing dimensions.

[0039] 4) In the six-sided CNC drilling equipment, the spindle dust cover 3-11 of the lower drill head 3 is located on the side of the manual tool-changing spindle 3-4 facing away from the spindle base plate 3-2, and the drill bag dust cover 3-16 of the drill bag 3-14 is located on the side of the drill bag 3-14 facing away from the spindle base plate 3-2. The dust suction ports of the spindle dust cover 3-11 and the drill bag dust cover 3-16 are arranged in front, which can further compress the structural dimensions of the lower drill head 3 in the direction of the head transverse guide rail, so that the structural design of the lower drill head 3 is more compact and can meet a wider range of processing dimensions.

[0040] 5) In the six-sided CNC drilling equipment, the two manual tool-changing spindles 3-4 of the lower drilling head 3 are arranged on the left side of the drilling package 3-14, that is, close to the reference side of the plate. The two manual tool-changing spindles 3-4 can avoid the gripper and the frame through the lifting cylinder 3-6. This layout enables the processing range of the vertical milling machine to meet the requirements of milling through grooves in plates with a width of 0-1220mm.

[0041] 6) In the six-sided CNC drilling equipment, the gripper transverse guide rail 4-1 is arranged on the upper side of the gripper support beam 4, and the second gear rack pair 4-2 is arranged on the left side of the gripper support beam 4 (i.e., the side away from the manual tool changing spindle 3-4). This arrangement allows the double lower spindles to be avoided under the gripper support beam 4, ensuring that all drill bits of the drill package 3-14 can cover the drilling processing on the reference side of the plate.

[0042] 7) In the six-sided CNC drilling equipment, the linear bearing seat 3-17-5 of the support device 3-17 is fixed on the shell side of the drill package 3-14, and the support surface of the support device 3-17 is at the same height as the support surface of the workbench 1. The guide light axis 3-17-4 allows the drill package 3-14 to move along the Z-axis direction without affecting the height position of the support surface. When the support device 3-17 is grooving / drilling the plate at the same time, it provides support force for the plate, ensures the processing accuracy of grooving / drilling at the same time, and improves processing efficiency.

[0043] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
