[0009] The precision adjustment assembly includes an adjustment shaft that is horizontally inserted through the frame and a lifting sleeve that meshes with the adjustment shaft. The lower end of the lifting sleeve is connected to a rotary drill bit.

[0010] One end of the adjusting shaft is connected to a handwheel, and the other end is provided with a worm gear structure that mates with the external thread of the lifting sleeve rod;

[0011] Two symmetrically distributed V-shaped guide grooves are opened on the surface of the lifting sleeve, and wedge-shaped guide blocks are provided on the inner wall of the corresponding frame.

[0021] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] Example 1:

[0023] This embodiment provides a precision positioning drilling device, comprising:

[0024] Base platform 1;

[0025] A column 2 is located at the rear end of the base, and a workpiece platform 3 is provided in the middle of the column 2;

[0026] The frame-type lifting mechanism 4 is slidably connected to the column 2 via guide rails;

[0027] The precision adjustment assembly includes an adjustment shaft 5 horizontally passing through the frame and a lifting sleeve 8 meshing with the adjustment shaft 5. The lower end of the lifting sleeve 8 is connected to a rotary drill bit 10.

[0028] One end of the adjusting shaft 5 is connected to a handwheel 6, and the other end is provided with a worm gear structure that engages with the external thread of the lifting sleeve 8;

[0029] Two symmetrically distributed V-shaped guide grooves are opened on the surface of the lifting sleeve 8, and wedge-shaped guide blocks are provided on the inner wall of the corresponding frame.

[0030] In use, the workpiece is placed on the workpiece platform 3. The operator turns the handwheel 6, which drives the adjusting shaft 5 to rotate. The worm gear structure of the adjusting shaft 5 interacts with the external thread of the lifting sleeve 8, causing the lifting sleeve 8 to drive the rotating drill bit 10 to rise and fall. At the same time, the V-shaped guide groove on the surface of the lifting sleeve 8 cooperates with the wedge-shaped guide block on the inner wall of the frame to ensure that the lifting process is smooth and precise, effectively improving the verticality and positional accuracy of the drilling, and meeting the stringent requirements of precision machining for drilling accuracy.

[0031] The operator rotates handwheel 6, which in turn rotates adjusting shaft 5. One end of adjusting shaft 5 has a worm gear structure that engages with the external thread of lifting sleeve 8. Based on the worm gear transmission principle, when adjusting shaft 5 rotates, the worm gear drives lifting sleeve 8 to move vertically. Simultaneously, two symmetrically distributed V-shaped guide grooves are formed on the surface of lifting sleeve 8, corresponding to wedge-shaped guide blocks on the inner wall of the frame. During the movement of lifting sleeve 8, the V-shaped guide grooves and wedge-shaped guide blocks cooperate to guide and limit movement, ensuring that lifting sleeve 8 can only move stably in the vertical direction, avoiding swaying or deviation. This achieves precise adjustment of the height of the rotating drill bit 10, meeting the precision requirements of drilling position in precision machining.

[0032] Example 2:

[0033] This embodiment provides a precision positioning drilling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0034] It also includes a servo motor (not shown) located at the top of the frame, whose output shaft is connected to the top of the lifting sleeve 8 via a bevel gear set.

[0035] When a rapid adjustment of the height of the rotary drill bit 10 is required, the servo motor at the top of the frame is activated. The output shaft of the servo motor drives the lifting sleeve 8 to move up and down rapidly via a bevel gear set (not shown), achieving rapid positioning. This design combines the precision of manual fine-tuning with the efficiency of electric rapid adjustment, greatly improving operational efficiency and adapting to the needs of different processing rhythms.

[0036] When a rapid adjustment of the height of the rotary drill bit 10 is required, the servo motor at the top of the frame is activated. The output shaft of the servo motor is connected to the top of the lifting sleeve 8 via a bevel gear set. The bevel gear set can change the direction of force transmission, converting the horizontal rotational motion of the servo motor into the vertical lifting motion of the lifting sleeve 8. The servo motor features fast response and high control precision, enabling it to quickly drive the lifting sleeve 8 to the designated position, improving operational efficiency. It can also be combined with manual adjustment to meet the needs of drill bit height adjustment in different processing scenarios.

[0037] Example 3:

[0038] This embodiment provides a precision positioning drilling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0039] The handwheel 6 integrates a rotary encoder, and the encoder signal output terminal is connected to the digital display screen 9 located on the side of the frame.

[0040] When the operator rotates handwheel 6 for adjustment, the rotary encoder integrated in handwheel 6 detects the rotation angle and number of rotations in real time and transmits the signal to digital display screen 9. Digital display screen 9 displays the adjustment amount intuitively, allowing the operator to understand the adjustment data in real time, achieve precise adjustment, avoid processing errors caused by over- or under-adjustment, and improve the accuracy and stability of processing.

[0041] The handwheel 6 integrates a rotary encoder, whose signal output is connected to the digital display screen 9 on the side of the frame. When the operator rotates the handwheel 6 for adjustment, the rotary encoder detects the rotation angle and number of turns of the handwheel 6 in real time and converts this information into electrical signals, which are then transmitted to the digital display screen 9. The digital display screen 9 processes and displays the received signals, showing the adjustment amount of the handwheel 6 in an intuitive digital form. This allows the operator to accurately understand the positional changes of the rotary drill bit 10, achieving precise positioning and effectively avoiding machining errors caused by over- or under-adjustment.

[0042] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms fall within the scope of protection of this application.
