Description

Technical Field

[0001] This utility model relates to the field of machining technology for drilling parts, and in particular to a three-axis drilling machine. Background Technology

[0002] See appendix Figure 2 In the existing technology, the most commonly used method for drilling parts is a bench drill. When drilling, the positioning fixture 101 is fixed first, and then the workpiece 102 is put into the positioning fixture. The bench drill 103 is then pressed down to drill.

[0003] See appendix Figure 3 When drilling holes in other parts of the workpiece, the position and angle of the workpiece are changed manually, and then the drilling is performed by operating a bench drill.

[0004] During the drilling process described above, the drill bit on the drilling platform has to face different angles to drill. The operator cannot accurately control the force applied to the drill bit when pressing down. The feed rate and the displacement of the drill bit during pressing down are greatly deviated, resulting in severe wear and tear on the drill bit, frequent replacements, and low production efficiency.

[0005] For workpieces with fixed-position drilling, the repetitive operation and positioning are not only tedious, but also result in poor consistency of drilling positions for different parts. Utility Model Content

[0006] The purpose of this invention is to solve the above problems and provide a three-axis drilling machine that sets up a corresponding controllable feed drill for different hole positions, completes the processing of multiple holes in one operation, and matches the feed and rotation displacement of the drill bit to ensure processing accuracy and the service life of the drill bit.

[0007] The technical solution adopted by this utility model is: A three-axis drilling machine is characterized by comprising a base surface, on which a drilling unit is mounted. The drilling unit includes a slide rail and a displacement mechanism. A mounting plate is disposed on the slide rail, and the mounting plate is driven by the displacement mechanism to move on the slide rail in a direction parallel to the base surface. A drill bit holder and a servo motor are mounted on the mounting plate, and the servo motor drives the drill bit on the drill bit holder to rotate. The displacement direction of the mounting plate is the same as the feed direction of the drill bit. A limiting fixture is also disposed on the base surface, on which a workpiece is mounted, and the drilling position of the workpiece corresponds to the position of the drill bit.

[0008] Furthermore, the drill bit holder is equipped with multiple drill bits arranged side by side, and the multiple drill bits are connected to the output shaft of the servo motor via a synchronous belt.

[0009] Furthermore, the limiting fixture also includes an adjustment block disposed on the base surface, the adjustment block being connected to the workpiece to adjust the position between the workpiece and the limiting fixture.

[0010] Furthermore, a buffer structure is provided on the base surface. The buffer structure includes a bracket fixed to the base surface, and a buffer column is provided on the bracket. The buffer column cooperates with the contact plate on the drill bit frame to buffer the displacement of the drill bit frame.

[0011] Furthermore, the base surface is a vertical surface, and the displacement mechanism is a lifting mechanism.

[0012] Furthermore, the drilling unit consists of three parts, arranged in an equilateral triangle around the workpiece.

[0013] The beneficial effects of this utility model are: (1) Multi-station drill bits simultaneously drill holes at different positions on the parts; (2) The feed rate of the drill bit is adjusted by the lifting mechanism and in conjunction with the servo motor to match the rotational displacement of the drill bit; (3) The adjustment unit can be used to adapt to parts with different sizes of drilling positions.

Detailed Implementation

[0016] The specific implementation of the three-axis drilling equipment of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] See appendix Figure 1 The three-axis drilling equipment of this patent is set on a vertical base surface 1. Multiple drilling units 2 are installed on the base surface 1. Each drilling unit 2 includes a slide rail 3 and a displacement mechanism 4. A mounting plate 5 is set on the slide rail 3. The mounting plate 5 is driven by the displacement mechanism 4 to move on the slide rail 3 in a direction parallel to the base surface 1. A drill bit holder 6 and a servo motor 9 are installed on the mounting plate 5. The servo motor 9 drives the drill bit 7 on the drill bit holder 6 to rotate. The displacement direction of the mounting plate 5 is the same as the feed direction of the drill bit 7. A limiting fixture 10 is also set on the base surface 1. A workpiece 12 is installed on the limiting fixture 10. The drilling position of the workpiece 12 corresponds to the position of the drill bit 7.

[0018] Based on the multi-hole requirements of the components, multiple drill bits 7 can be arranged side-by-side on the drill bit holder 6. These drill bits 7 are connected to the output shaft of the servo motor 9 via a synchronous belt 8. This allows for simultaneous drilling of multiple holes in the same direction. For holes at different positions on the same side, the drill bits 7 can be positioned at different locations on the drill bit holder 6. Through different types of drive by the servo motor 9, multiple drill bits 7 can rotate synchronously. As the displacement mechanism 4 moves, the drive mounting plate 5 moves the entire drill bit holder 6 towards the workpiece 12, allowing the drill bits 7 to simultaneously drill holes at different positions on the workpiece 12. The displacement mechanism 4 uses a lifting cylinder to drive the mounting plate 5, causing it to move on the slide rail 3.

[0019] The limiting fixture 10 also includes an adjustment block 11 disposed on the base surface 1. The adjustment block 11 is connected to the workpiece 12 and adjusts the position between the workpiece 12 and the limiting fixture 10, as well as the horizontal angle of the workpiece 12, so that the multiple drilling units 2 can perform drilling on multiple surfaces of the workpiece 12.

[0020] Each drilling unit 2 also includes a buffer structure 13 for absorbing and cushioning vibrations generated during drilling. The buffer structure 13 is mounted on the base surface 1 and includes a bracket 14 fixed to the base surface 1. Buffer columns 15 are mounted on the bracket 14, and the buffer columns 15 cooperate with the contact plates on the drill bit holder 6 to buffer the displacement of the drill bit holder 6. The buffer columns 15 can be commercially available spring-type buffer products, and the amount of vibration absorbed during buffering can be adjusted according to the position of the buffer columns 15 on the bracket 14.

[0021] Multiple drilling units 2 on the base surface 1 are arranged at different angular positions on the workpiece 12 limiting fixture 10, forming an equilateral triangle in the figure. The drilling positions correspond to three positions on the workpiece 12. After the workpiece 12 is fixed and limited by the limiting fixture 10, the displacement mechanism 4 of each drilling unit 2 is driven to perform drilling work. Drilling is carried out in multiple directions simultaneously, which not only improves work efficiency but also enables the cancellation of feed forces in multiple directions.

[0022] When the base surface 1 is vertically arranged, the displacement mechanism 4 achieves the lifting function. The base surface 1 can also be arranged horizontally, allowing for horizontal drilling operations on a horizontal worktable.

[0023] The entire device is controlled by an electrical control system, primarily controlling the displacement mechanism 4 and the servo motor 9. Different stroke amounts are set to control the corresponding feed and rotational displacements. The electrical control principle utilizes commonly used control techniques from existing technologies.

[0024] The servo motor 9 driving method and the pneumatic driving method of the displacement mechanism 4 in this patent are both common forms in the prior art. The technical solution of this patent is that the displacement mechanism 4 and the servo motor 9 work together to match the feed amount and rotational displacement of the drill bit 7, and realize the function of simultaneous processing at multiple stations.

[0025] This patent can also be used for similar machining processes other than drilling rigs, such as grinding machines and planers.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
