Description

Technical Field

[0001] This utility model relates to drill bits, and more specifically, to a linear multi-drill bit mechanism. Background Technology

[0002] A drill bit is a tool used in drilling operations to create holes in solid materials such as metal, wood, rock, and concrete. It works by rotating and applying axial force, causing the cutting edge of the drill bit to interact with the material and remove it to form a hole. Drill bits play a crucial role in many fields, including machinery manufacturing, construction, geological exploration, and oil extraction.

[0003] The technical features of the multi-station synchronous drilling mechanism disclosed in Chinese Patent Announcement No. CN216632700U are as follows: it includes a base, a driving mechanism and a drilling mechanism. The driving mechanism and the drilling mechanism are both arranged above the base. A fixing frame is welded to the upper surface of the base. A placement platform is fixedly connected to the upper surface of the base near the fixing frame. A support frame is fixedly connected to the upper surface of the base near the placement platform.

[0004] In the above technical solution, the existing drilling mechanism can only drill a single hole. When multiple holes need to be drilled, the position of the workpiece needs to be changed, which is time-consuming and laborious, reducing work efficiency. In addition, the workpiece needs to be manually held during the drilling process, which poses a safety hazard.

[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0031] like Figures 1 to 2As shown, a linear multi-drill mechanism includes two sets of material drilling mechanisms. One set of material drilling mechanisms is located on one side of the other material drilling mechanism. Each material drilling mechanism includes a drilling frame 1, on which a set of transverse guide rail mechanisms are provided. A transverse slide plate 2 is provided on the transverse guide rail mechanisms. A transverse movement drive mechanism is provided at the bottom of the transverse slide plate 2. A drilling mechanism for drilling materials is provided on one side of the transverse slide plate 2. A longitudinal movement guide mechanism is provided on both sides of the drilling mechanism. A longitudinal movement drive mechanism is provided on the longitudinal movement guide mechanism. A synchronous rotation mechanism is provided on one side of the drilling mechanism.

[0032] The two punching frames 1 in the two sets of material punching mechanisms are arranged at different heights, with one punching frame 1 being taller than the other. The taller punching frame 1 is positioned to one side of the shorter punching frame 1. Due to the height difference between the two punching frames 1, the corresponding mechanisms on each punching frame 1 are relatively independent, preventing mutual interference and providing multiple workstations to improve production efficiency. The two sets of material punching mechanisms are arranged side-by-side, with each set operating based on a punching frame 1. The transverse guide rail mechanism installed on the punching frame 1 provides a moving track for the transverse slide plate 2. The transverse drive mechanism drives the transverse slide plate 2 to move laterally on the transverse guide rail mechanism. By controlling the transverse drive mechanism, the position of the transverse slide plate 2 can be precisely adjusted so that the drilling mechanism reaches the designated position in the transverse direction, preparing for the subsequent drilling operation. The longitudinal drive mechanism drives the drilling mechanism to move longitudinally along the longitudinal guide mechanism. The longitudinal guide mechanism provides guidance for the drilling mechanism's movement in the longitudinal direction. While the longitudinal drive mechanism drives the drilling mechanism to move longitudinally, the synchronous rotation mechanism also drives the drilling mechanism to move longitudinally and rotate accordingly during the longitudinal movement. The synchronous rotation mechanism and the longitudinal drive mechanism work together to enable the drilling mechanism to rotate simultaneously during the longitudinal movement, drilling holes in the corresponding material.

[0033] like Figures 2 to 4 As shown, the transverse guide rail mechanism includes two transverse slide rod seats 3, which are bolted to the top of the drilling machine frame 1 on both sides. Two transverse sliding rods 4 are arranged between the two transverse slide rod seats 3. Several transverse sliding tables 5 are slidably connected to the two transverse sliding rods 4. The transverse sliding tables 5 are bolted to the transverse slide plate 2. The transverse movement drive mechanism includes a transverse movement synchronous belt 6. A transverse movement drive wheel 7 and a transverse movement driven wheel 8 are wound around the transverse movement synchronous belt 6. A pressure plate seat 9 is also arranged on the transverse movement synchronous belt 6. The pressure plate seat 9 is bolted to the transverse slide plate 2. The transverse movement drive wheel 7 is driven by a drive component 10. The drive component 10 is set on the surface of the transverse slide plate 2 through a transverse motor seat 11. The shaft of the transverse movement driven wheel 8 is connected to a transverse slide rod seat 3 by a fixing bolt.

[0034] The drive unit 10 is a device combining a geared motor and a servo motor. The transverse slide 5 can slide on the transverse sliding rod 4, providing sliding support for the transverse slide plate 2, allowing it to move laterally on the transverse sliding rod 4. When the drive unit 10 is activated, it drives the transverse drive wheel 7 to rotate, which in turn causes the transverse timing belt 6 to move. The movement of the transverse timing belt 6 drives the transverse slide plate 2 to move laterally on the transverse sliding rod 4 through the pressure plate seat 9, realizing the lateral position adjustment of the transverse slide plate 2 and its connected components. The shaft of the transverse driven wheel 8 is connected to a transverse slide rod seat 3 by fixing bolts, serving as support and positioning.

[0035] like Figures 5 to 7 As shown, the drilling mechanism includes a drill bit main seat 12, a rotating spindle 13 is provided on the drill bit main seat 12, several drill bit slave seats 14 are provided on both sides of the drill bit main seat 12, and a rotating slave shaft 15 is provided on each of the drill bit slave seats 14. A first transmission wheel 16 and a second transmission wheel 17 are provided on one side of the rotating spindle 13 and the rotating slave shaft 15. A first drill bit timing belt 18 is connected to two adjacent first transmission wheels 16, and a second drill bit timing belt 19 is connected to two adjacent second transmission wheels 17. A three-pointed drill 20 is provided on the other side of the rotating spindle 13 and the rotating slave shaft 15. A longitudinal slide plate 21 is provided at the bottom of the drill bit main seat 12 and the drill bit slave seat 14, and the longitudinal slide plate 21 is slidably connected to the transverse slide plate 2.

[0036] The drill bit main seat 12 and drill bit slave seat 14 on the longitudinal slide plate 21 can move in the direction provided by the longitudinal guide mechanism through the longitudinal drive mechanism and the synchronous rotation mechanism. During the movement, the synchronous rotation mechanism is the power source and is connected to the rotating main shaft 13. The rotating main shaft 13 rotates accordingly, which drives the first transmission wheel 16 and the second transmission wheel 17 to rotate accordingly. The first transmission wheel 16 and the second transmission wheel 17 can drive the adjacent rotating wheel through the first drill bit synchronous belt 18 and the second drill bit synchronous belt 19. The rotating shaft 15 rotates accordingly. Through this transmission method, several rotating shafts 15 adjacent to both sides of the rotating main shaft 13 can rotate accordingly. The rotation of the rotating main shaft 13 and the rotating shafts 15 can drive the three-point drill 20 to rotate accordingly. In the above process, the rotation and longitudinal displacement of the three-point drill 20 are synchronized, so that the three-point drill 20 can perform corresponding drilling operations on the material. The three-point drill 20 is set at the end of the rotating main shaft 13 and the rotating shaft 15 that is away from the first transmission wheel 16 and the second transmission wheel 17, that is, the end facing the material.

[0037] like Figures 5 to 6As shown, the longitudinal guide mechanism includes a longitudinal sliding rod 22, on which several longitudinal sliding tables 23 are slidably connected. A longitudinal connecting plate 24 is bolted to the longitudinal sliding table 23. The longitudinal connecting plate 24 is bolted to the longitudinal sliding plate 21. A longitudinal sliding rod seat 25 is provided on both sides of the longitudinal sliding rod 22. Both longitudinal sliding rod seats 25 are bolted to the transverse sliding plate 2. The longitudinal drive mechanism includes a longitudinal synchronous belt 26. A longitudinal driving wheel 27 and a longitudinal driven wheel 28 are wound around the longitudinal synchronous belt 26. A longitudinal drive screw 29 is provided on both the longitudinal driving wheel 27 and the longitudinal driven wheel 28. The longitudinal drive screw 29 passes through the longitudinal sliding rod seat 25 on one side and is rotatably supported on the longitudinal sliding rod seat 25. A screw transmission plate 30 is threadedly connected to the longitudinal drive screw 29. The screw transmission plate 30 is threadedly fixed to the longitudinal connecting plate 24. A longitudinal drive motor 31 is drivenly connected to the longitudinal driving wheel 27. The longitudinal drive motor 31 is bolted to the transverse sliding plate 2 through a longitudinal motor seat 32.

[0038] The longitudinal slide block seat 25 provides support and fixation for the longitudinal slide rod 22. When the longitudinal drive motor 31 starts, it drives the longitudinal drive wheel 27 to rotate. The rotation of the longitudinal drive wheel 27 drives the longitudinal driven wheel 28 to rotate synchronously through the longitudinal synchronous belt 26. When the longitudinal drive wheel 27 and the longitudinal driven wheel 28 rotate, they drive the longitudinal drive screw 29 to rotate. The rotation of the longitudinal drive screw 29 is converted into the linear motion of the screw drive plate 30, which in turn drives the longitudinal connecting plate 24 and the longitudinal slide plate 21 to move longitudinally along the longitudinal slide rod 22, thereby realizing the longitudinal position adjustment of the longitudinal slide plate 21 and the connected components.

[0039] like Figures 5 to 6 As shown, the synchronous rotation mechanism includes a rotary motor 33, which is fixed to the surface of the transverse slide plate 2 by four support column bolts. A motor pulley 34 is provided on the output shaft of the rotary motor 33. The motor pulley 34 is connected to a rotary synchronous belt 35. A drive pulley 36 is wound around the rotary synchronous belt 35. The drive pulley 36 is fixed to the transverse slide plate 2 by drive seats 37 on both sides. A rotary lead screw 38 is provided on the drive pulley 36. The rotary lead screw 38 is connected to the rotary spindle 13 of the drill bit main seat 12.

[0040] The synchronous rotation mechanism and the longitudinal drive mechanism move synchronously. While the drive screw rotates and drives the lead screw transmission plate 30 to move linearly, the rotary motor 33 starts. The rotary motor 33 drives the motor pulley 34 to rotate through its output shaft. The rotation of the motor pulley 34 will drive the drive pulley 36 to rotate synchronously through the rotary synchronous belt 35. The rotation of the drive pulley 36 can drive the rotary lead screw 38 to rotate accordingly. The rotary lead screw 38 can drive the rotary main shaft 13 to rotate accordingly through the coupling. At the same time, the corresponding rotation of the threaded end of the rotary lead screw 38 can also cooperate with the longitudinal drive mechanism to complete the displacement of the longitudinal slide plate 21.

[0041] like Figures 5 to 6 As shown, a reinforcing crossbeam 39 is provided between the two longitudinal connecting plates 24.

[0042] The reinforcing beam 39 can effectively resist the deformation caused by these external forces, ensuring the structural stability of the longitudinal connecting plate 24 and the longitudinal sliding plate 21. When the longitudinal sliding plate 21 moves on the longitudinal sliding rod 22, the reinforcing beam 39 can limit the relative displacement between the two longitudinal connecting plates 24, reduce the shaking of the longitudinal sliding plate 21 during the movement, and enable the two longitudinal connecting plates 24 to remain synchronized during the movement.

[0043] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
