[0028] The following is a combination of the appended examples of the present invention Figures 1-4 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0029] like Figure 1 、 2 As shown, an adjustable drilling machine is proposed, comprising:

[0030] Rack 1;

[0031] A platform-like workbench 3 is connected to the frame 1 in a manner that can be raised and lowered, and a positioning structure for positioning the wood material 4 is installed on its upper side;

[0032] Multiple drilling devices are located directly above the workbench 3 and are used to drill holes in the wooden material 4. The drilling device includes a drilling motor 12, a drill bit 121 and a motor adjustment bracket 13. The drill bit 121 is connected to the drilling motor 12 in a transmission manner. The drilling motor 12 can be installed on the motor adjustment bracket 13 so as to be horizontally adjustable along the X direction. The motor adjustment bracket 13 can be installed on the frame 1 so as to be horizontally adjustable along the Y direction. After adjustment, the drill bit 121 is aligned with the position on the wooden material 4 where a hole needs to be drilled. That is, the specific positions of the drilling motor 12 and its drill bit 121 can be precisely adjusted according to the point where the hole needs to be drilled, so that the drill bit 121 can be aligned with the point on the wooden material 4 where a hole needs to be drilled.

[0033] During drilling, the workbench 3 is lifted up and placed together with the wood material 4 in a drilling operation position so that the drill bit 121 can drill holes in the wood material 4 .

[0034] like Figure 3 As shown, the drill bit 121 is a rod-shaped drill bit, which is fixedly connected to the output end of the drilling motor 12. When drilling, the drilling motor 12 drives the drill bit 121 to rotate at high speed so as to drill holes on the wooden material 4.

[0035] The drill bit 121 and the drilling motor 12 can be replaced according to project requirements. The drill bit 121 is detachably connected to the output end of the drilling motor 12, and the specifications (such as length) of the drill bit 121 can be replaced according to project requirements.

[0036] like Figure 4 As shown, because the wooden material 4 will vibrate during the drilling process, the above-mentioned drilling device is also equipped with an elastically retractable pre-pressing component 14 for pre-pressing the wooden material 4. The pre-pressing component 14 is fixedly connected to the motor adjustment bracket 13. The lower end of the pre-pressing component 14 is lower than the lower end of the drill bit 121 and presses the wooden material 4 before the drill bit 121 during drilling. The pre-pressing component 14 can be set as a gas spring or other elastically retractable structure, that is, a telescopic rod structure that can be elastically retracted up and down. After installation, the lower end of the pre-pressing component 14 is about 20 mm lower than the lower end of the drill bit 121 (or other dimensions), ensuring that the pre-pressing component 14 contacts the wooden material 4 earlier than the drill bit 121, ensuring the effect of pressing the wooden material 4, and preventing the wooden material 4 from being offset during the drilling process, resulting in a decrease in drilling accuracy and quality.

[0037] The pre-pressing components 14 of all drilling devices press the wood material 4 together, so that the pressing effect of the wood material 4 is reliable and stable.

[0038] The drilling machine further comprises a workbench jacking cylinder 2 installed in the frame 1, the piston rod of the workbench jacking cylinder 2 is upward, which supports and connects the lower side of the workbench 3, so as to better bear the heavy load of the workbench 3. The workbench jacking cylinder 2 is vertically arranged, the cylinder barrel is fixed on the cylinder support rod 102, and the cylinder support rod 102 is fixedly arranged in the frame 1.

[0039] As a preferred embodiment, the workbench 3 is fixedly connected with a lifting sliding block 10, and the frame 1 is fixedly connected with a vertical lifting rail 11, and the lifting sliding block 10 and the lifting rail 11 are slidably matched to guide the lifting track of the workbench 3. The number of the lifting sliding block 10 and the lifting rail 11 is not limited here.

[0040] As a preferred embodiment, as shown in Figure 3 The motor adjusting support 13 comprises a main cross beam 132 and an adjusting plate 131 which are fixedly connected, the drilling motor 12 is adjustably installed on the adjusting plate 131, and the main cross beam 132 is adjustably installed on the frame 1.

[0041] The adjusting plate 131 is provided with a plurality of adjusting holes 131a for penetrating the fasteners of the drilling motor 12, and the adjusting holes 131a are strip-shaped holes extending horizontally and used for guiding the adjusting direction of the drilling motor 12.

[0042] The main cross beam 132 extends horizontally as a whole, and both ends of the main cross beam 132 are fixedly provided with end fixed plates 133 which are horizontally adjustably connected with the two upper cross beams 101 on the upper side of the frame 1, and the adjusting direction of the end fixed plates 133 is perpendicular to the length direction of the adjusting holes 131a, so that the drilling motor 12 and the drill bit 121 can be horizontally adjusted in two directions perpendicular to each other, so as to adapt to different drilling positions.

[0043] More specifically, the end fixed plates 133 are provided with two fixed holes, and the upper cross beams 101 are provided with a plurality of optional positioning holes in the adjusting direction, the motor adjusting support 13 can be adjusted along the length direction of the upper cross beams 101, the positioning holes at the corresponding positions are selected, the fasteners are used to penetrate the fixed holes of the end fixed plates 133 and the positioning holes at the corresponding positions, so as to lock the position of the motor adjusting support 13 on the upper cross beams 101.

[0044] In addition, the adjusting plate 131 is provided as a vertical plate structure, and the adjusting holes 131a are provided as long circular holes (strip-shaped holes), so that the drilling motor 12 can be horizontally adjusted along the length direction of the adjusting holes 131a, so as to horizontally adjust the position of the drilling motor 12 in a direction perpendicular to the upper cross beams 101, and then the fasteners are used to penetrate the adjusting holes 131a and the fixed holes of the motor seat, so as to lock the drilling motor 12.

[0045] As a preferred embodiment, the positioning structure of the workbench 3 includes a plurality of positioning stops installed on the upper side of the workbench 3 . During positioning, the positioning stops abut against the edge of the wooden material 4 and are distributed along the length direction of the wooden material 4 .

[0046] The positioning structure of the above-mentioned workbench 3 also includes an automatic pressing component installed on the upper side of the workbench 3. Two or other numbers of automatic pressing components can be set. During positioning, the automatic pressing component rests against the edge of the wooden material 4 and clamps the wooden material 4 together with the positioning stop.

[0047] The specific setup is as follows: To position the rectangular wood material 4, the positioning blocks are divided into several rear blocks 7, a side block 8, and two stop rods 9. Two automatic clamping assemblies are provided, each comprising a clamping cylinder 5 and a clamping block 6 fixedly mounted at the end of the piston rod of the clamping cylinder 5. The cylinder barrel of the clamping cylinder 5 is mounted on the upper side of the workbench 3. The rear block 7 and stop rod 9 are fixedly connected to the workbench 3 and serve as the initial positioning reference for the wood material 4. The side blocks 8 are removable and / or adjustable to accommodate wood materials 4 of different specifications.

[0048] During positioning, with the pressing cylinder 5 in front, the wooden material 4 is placed on the upper side of the workbench 3, so that the rear long side and one of the short sides of the wooden material 4 are respectively against the rear stop block 7 and the side stop block 8, and the other short side of the wooden material 4 is against the gear rod 9 fixed on the workbench 3, thereby positioning the wooden material 4.

[0049] The pressing cylinder 5 is used to drive the pressing block 6 to extend toward the front long side of the wood material 4 so that the pressing block 6 presses the front long side of the wood material 4, thereby locking the wood material 4 on the workbench 3.

[0050] When drilling, the workbench lifting cylinder 2 lifts the workbench 3 to the drilling operation position, and the several drill bits 121 on it correspond one by one to the positions where holes need to be drilled. The pre-pressing component 14 contacts the wooden material 4 earlier than the drill bit 121 to ensure the effect of pressing the wooden material 4. During the drilling process, the pre-pressing component 14 is always in contact with the wooden material 4, and the drill bit 121 rotates at high speed to drill. Each drill bit 121 drills a hole at the corresponding position until the hole is completely drilled through. After the drilling is completed, the workbench lifting cylinder 2 contracts and brings the workbench 3 downward, so that the drill bit 121 and the pre-pressing component 14 are completely separated from the wooden material 4, and then the pressing cylinder 5 is released so that the wooden material 4 can be removed immediately.

[0051] To sum up, the drilling machine has the following advantages:

[0052] The drilling device is adjustably arranged above the workbench 3. When drilling, the wood material 4 can be easily positioned on the workbench 3, and the workbench 3 can be driven upward to perform the drilling operation on the wood material 4.

[0053] The versatility is strong. Since the drilling device can be adjusted, the specific positions of the drilling motor 12 and its drill bit 121 can be accurately adjusted according to the drilling point required, so that the drill bit 121 can be aligned with the point on the wooden material 4 where the hole needs to be drilled. It can flexibly drill wooden materials 4 with different hole positions and ensure the drilling accuracy.

[0054] The drilling efficiency is high. For wood materials 4 of the same specification, under the premise of adjusting the drilling device in place, it is only necessary to quickly position the wood material 4 and lift the workbench 3 to the drilling operation position to perform the drilling operation quickly, which is convenient for batch operation.

[0055] High flexibility, the drilling cycle can be adjusted at will by adjusting the control program during use.

[0056] To improve work efficiency, the following measures can be adopted:

[0057] 1. By selecting the appropriate motor power, the length of the drill bit 121 and the cylinder stroke, multiple wooden boards 4 are placed on the workbench 3 at the same time and drilled at the same time (this design can meet the requirements of drilling 4 boards at the same time);

[0058] 2. By adjusting the cylinder controller program, the workbench lifting cylinder 2 and the pressing cylinder 5 can be controlled to operate simultaneously. By adjusting the cylinder speed, it is only necessary to ensure that the pressing cylinder 5 is completed before the drill bit 121 contacts the wood material 4. This can further shorten the drilling cycle.

[0059] 3. Under the premise of ensuring the drilling quality, the cylinder speed can be increased and the drilling cycle can be shortened by adjusting the cylinder controller program.
