Description

Technical Field

[0001] This utility model relates to the field of vertical drilling rig technology, specifically a vertical drilling rig device. Background Technology

[0002] In this vertical drilling rig, the complete spindle box assembly moves on a dedicated column. The rig also features a fixed base on the column for limiting the lower travel of the spindle box. This fixed base is mostly constructed using a slit clamping clamp, which is radially secured to the column by a swing-out locking handle. Two pneumatic rods are positioned between the spindle box and the fixed base. After the fixed base is locked, the spindle box drives the spindle downwards to process the workpiece. After processing, the entire spindle box springs back to its original position on the column, overcoming the force applied by the pneumatic rods.

[0003] Disadvantages of existing technology: As is known in existing technology, the headstock and motor of traditional vertical drilling rigs are fixed at the top. The worktable position must be moved to meet processing requirements depending on the thickness of the workpiece. This is cumbersome, and the small worktable surface is not conducive to fixing longer workpieces. Most existing vertical drilling rigs with movable headstocks are non-belt driven, resulting in higher noise levels and a poor user experience.

[0004] The purpose of this invention is to provide a new vertical drilling machine that drives the cutting tool to move up and down along the column axis between the spindle box and the fixed base, enabling safe and rapid processing of wooden workpieces of any thickness. Furthermore, this vertical drilling machine uses a multi-wedge belt drive, resulting in low noise, adjustable belt tension, and convenient operation. Utility Model Content

[0011] As a preferred embodiment of this utility model, a tensioning handle is internally threaded on one side of the spindle box assembly, and one end of the tensioning handle is rotatably connected to a guide block through the spindle box.

[0013] The beneficial effects of this utility model are:

[0014] 1. This type of vertical drilling rig device, by setting up a pneumatic rod, allows the spindle box, motor, and cutting tool to be raised and lowered together, and automatically rebounds after processing is completed by the pneumatic rod, making operation more convenient and safer;

[0015] 2. This type of vertical drilling rig device, by setting a tensioning wheel, opens the top cover by rotating the rotary handle, and simultaneously rotates the tensioning handle clockwise.

Finally, closing the top cover and rotating the rotary handle clockwise completes the entire shifting process.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figures 1-5 As shown, this utility model discloses a vertical drilling rig device, including a base 5, a column 1 fixedly installed on the upper surface of one end of the base 5, a spindle box assembly 2 slidably connected to the outer peripheral surface of the column 1, a lifting handle 3 rotatably connected to the outer peripheral surface of the spindle box assembly 2, a baffle 4 movably connected to the top surface of the base 5, a spindle box 6 fixedly installed inside the spindle box assembly 2, a fixed seat 7 fixedly connected to one side of the column 1, a locking handle 8 rotatably connected to the lower end of one side of the spindle box assembly 2, and pneumatic rods 9 symmetrically fixedly installed on both sides of the spindle box assembly 2, with the output end of the pneumatic rod 9 fixedly connected to the fixed seat 7.

[0026] Among them, a rack 10 is fixedly connected to one side of the column 1, and a lifting spindle 12 is fixedly connected to one side of the lifting handle 3. One end of the lifting spindle 12 passes through the spindle box assembly 2 and is fixedly connected to a gear 11. The outer circumference of the gear 11 meshes with the rack 10. By setting the rack 10, the vertical position of the spindle box assembly 2 can be precisely controlled through the meshing of the gear 11 and the rack 10, ensuring the accuracy of the drilling position.

[0027] The spindle box assembly 2 houses a motor 13, whose output end passes through the spindle box 6 and is connected to a motor pulley 14. The outer circumference of the motor pulley 14 is connected to a spindle pulley 15 via a multi-ribbed belt 21. By setting the motor 13, the motor pulley 14 is directly mounted on the output shaft of the motor 13. When the motor 13 starts, the rotational motion of the motor 13 is transmitted to the spindle pulley 15 through the multi-ribbed belt 21. Simultaneously, the multi-ribbed belt 21 provides transmission with low noise, allows for belt tensioning, and facilitates operation.

[0028] The main shaft 16 is fixedly connected to the lower end of the main shaft pulley 15, and a drill chuck 17 is fixedly installed at the bottom of the main shaft 16. By setting the drill chuck 17, the drill bit is firmly clamped and prevented from loosening or falling off during high-speed rotation.

[0029] The top of the spindle box assembly 2 is rotatably connected to an upper cover 18. A rotating handle 19 is rotatably connected to one side of the surface of the upper cover 18. One end of the rotating handle 19 passes through the upper cover 18 and is threadedly connected to the top of the spindle box assembly 2. The upper cover 18 can be locked by setting the rotating handle 19.

[0030] The spindle box assembly 2 has a tensioning handle 20 internally threaded on one side. One end of the tensioning handle 20 passes through the spindle box 6 and is rotatably connected to a guide block 24. By setting the tensioning handle 20, the position of the guide block 24 can be adjusted, and the position of the tensioning wheel 22 can be moved at the same time.

[0031] The spindle box 6 is fixedly connected to a guide plate 23. The upper end of the guide plate 23 is slidably connected to a guide block 24. The upper end of the guide block 24 is rotatably connected to a tension wheel 22. The outer periphery of the tension wheel 22 is connected to the multi-ribbed belt 21 for transmission. By setting the tension wheel 22 and adjusting its position, the tension of the multi-ribbed belt 21 can be changed.

[0032] Working principle: In use, a special clamp is used to fix the workpiece onto the base 5 through a special hole on the base 5. After loosening the locking handle 8, the spindle box assembly 2 is moved to a certain position along the axial direction of the column 1 through the meshing of the rack 10 and gear 11. Then, the locking handle 8 is rotated to radially fix the fixing seat 7 onto the column 1. Then, the lifting handle 3 is rotated counterclockwise. Figure 1(In the middle) The lifting spindle 12 drives the gear 11 to move downward along the rack 10 on the column 1, which in turn drives the drill chuck 17 and the cutting tool to process the workpiece. During the downward pressing process, the two pneumatic rods 9 are compressed. After the processing is completed, the lifting handle 3 is released, the pneumatic rods 9 are released, and the spindle box assembly 2 is driven to rise in the opposite direction to the original position.

[0033] refer to Figure 3-5 This vertical drilling rig has two speeds, high and low, and the multi-wedge belt 21 is located in Figure 4 The current position indicates a low gear. When shifting gears, the user rotates the rotary handle 19 counterclockwise to open the top cover 18, and simultaneously rotates the tension handle 20 clockwise. This causes the guide block 24 and tension wheel 22 to move closer to the pulley side via bolts, thus slackening the multi-ribbed belt 21. Then, the multi-ribbed belt 21 is shifted to a high gear. Rotating the tension handle 20 counterclockwise causes the guide block 24 and tension wheel 22 to tighten the multi-ribbed belt 21 to the appropriate position via bolts. Finally, the top cover 18 is closed, and the rotary handle 19 is rotated clockwise to complete the shifting process.
