The worktable is provided with two parallel guide rails along the longitudinal direction. A sliding platform is connected to the guide rails through linear bearings. A workpiece clamping device is provided on the table surface of the sliding platform. The workpiece clamping device includes side baffles and workpiece clamps. The two side baffles are symmetrically arranged on both sides of the axis of the pre-processed workpiece and fixed on the table surface of the sliding platform. The workpiece clamp is fixed on the side baffles. The clamping part of the workpiece clamp presses the workpiece from top to bottom. A tailstock is provided at the rear end of the sliding platform. A center device is provided on the tailstock.

[0009] like Figure 1 , 2As shown in Figure 3, a drilling machine for deep drilling of wooden parts includes a worktable 1, a drill bit drive device 2, a drill rod chuck 3, and a drill bit 4. The worktable 1 has two parallel guide rails 5 along its longitudinal direction. A sliding platform 6 is connected to the guide rails 5 via linear bearings. A workpiece clamping device is provided on the surface of the sliding platform 6. The workpiece clamping device includes side baffles 7 and workpiece clamps 8. The two side baffles 7 are symmetrically arranged on both sides of the axis of the pre-processed workpiece and fixed to the surface of the sliding platform 6. The workpiece clamps 8 are fixed to the side baffles 7, and the clamping part of the workpiece clamps 8 presses the workpiece from top to bottom. A tailstock 9 is provided at the rear end of the sliding platform 6, and a center device is provided on the tailstock 9. Under the constraint of the sliding platform surface and the two side baffles, placing the pre-processed wooden workpiece on the sliding platform will easily align it with the center and the drill rod on the same axis. The wooden workpiece is held in place by the center and fixed with the clamps, and the sliding platform can be manually pushed to complete the deep hole machining. The drill bit drive device includes a drive motor and a reducer.
[0010] The workpiece clamp 8 includes a clamping part 10, a driving block 11, a lower hinge handle 12, an upper hinge handle 13, an intermediate connecting rod 14, and an unlocking lever 15. The clamping part 10 is located at the front end of the driving block 11. The lower hinge handle 12 and the upper hinge handle 13 are respectively hinged to the bottom and top of the rear end of the driving block 11. The two ends of the intermediate connecting rod 14 are respectively hinged to the upper hinge handle 13 at a forward position and the lower hinge handle 12 at a rearward position. A return spring 16 is provided between the driving block 11 and the lower hinge handle 12. The unlocking lever 15... The front end is hinged to the upper hinge handle 13. This hinge point is located behind the hinge point between the upper hinge handle 13 and the intermediate connecting rod 14. The front end of the unlocking lever 15 has a protrusion 17 for abutting against the intermediate connecting rod 14. When the lever is pressed down so that the included angle between the three hinge points on the upper hinge handle 13 and the intermediate connecting rod 14 (the three hinge points connecting the upper hinge handle and the drive block, the upper hinge handle and the intermediate connecting rod, and the intermediate connecting rod and the lower hinge handle) exceeds 180 degrees, the intermediate connecting rod 14 just presses the unlocking lever 15 against the upper hinge handle 13. The drive block, lower hinge handle, upper hinge handle, and intermediate connecting rod form an unequal-sided four-bar linkage, in which the two hinge points on the lower hinge handle are the longest, while the sum of the lengths between the hinge points on the upper hinge handle and the intermediate connecting rod is roughly the same as the length on the lower hinge handle. To clamp the workpiece, press down on the upper hinge handle until the hinge point of the upper hinge handle and the middle connecting rod are nearly aligned, that is, before exceeding 180 degrees. The clamping part will then just clamp the workpiece. Continue pressing down; the closer to 180 degrees, the greater the force required. Continuing to press down, through the deformation of related components, causes the middle hinge point on the upper hinge handle and the middle connecting rod to cross the 180-degree angle (the three hinge points forming a straight line). At this point, the upper hinge handle will move downwards without further force, but it will immediately stop moving downwards due to the immediate restriction of the unlocking lever. This firmly fixes the workpiece. The function of the return spring is to widen the angle between the upper hinge handle and the middle lever when the unlocking lever is activated, causing the middle hinge point on the upper hinge handle and the middle connecting rod to return to the 180-degree angle. Under the pull of the return spring, the upper hinge handle will open, moving the clamping part away from the workpiece. The unlocking lever uses a lever principle to achieve the purpose of saving effort and making unlocking easier.
[0011] An adjusting bolt 18 is screwed to the rear of the lower hinge handle 12. A movable hinge part 19 is rotatably connected to the front end of the adjusting bolt 18. The intermediate connecting rod 14 is connected to the lower hinge handle 12 through the movable hinge part 19. The adjusting bolt can adjust the distance between the two hinge points on the lower hinge handle, thereby adjusting the opening size of the clamping part to accommodate workpieces of different sizes.
[0012] A spring is provided between the intermediate connecting rod 14 and the upper hinge handle 13 to drive them to come into contact. A tension spring can be provided between them, or a torsion spring can be provided at the hinge point between them to make them fit together tightly.
[0013] The clamping part 10 is a vertically arranged rod-shaped body with a clamping head 20 at its lower end. The clamping part 10 is screwed to the driving block 11 via a threaded connecting sleeve 21 fixed on the driving block 11. The clamping part 10 is provided with a locking nut 22 that cooperates with the threaded connecting sleeve 21 to lock it in place. The clamping part can be rotated to adjust its height to accommodate workpieces of different sizes.
[0014] The tip device includes a screw 23, a tip 24, and a handwheel 25. The screw 23 is screwed onto the tailstock 9, and the tip 24 and the handwheel 25 are respectively located at both ends of the screw 23.
[0015] The tip 24 is a quincunx tip with a central cavity. The cavity can avoid the drill bit, allowing the hole to be drilled in one go.
