[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-3As shown, this utility model provides a drilling fixture for hardware parts, including a housing 1 and a mounting arm 2 connected to the housing 1. The mounting arm 2 is movably connected to the housing 1. The mounting arm 2 is provided with a first clamping structure 3, a second clamping structure 301 and a chip removal system 4. The mounting arm 2 is also provided with a height fine adjustment mechanism and a clamping mechanism 201. The first clamping structure 3 and the second clamping structure 301 are respectively connected to the clamping mechanism 201. The first clamping structure 3 and the second clamping structure 301 respectively include a first drilling station 302 and a second drilling station 309. Both the first drilling station 302 and the second drilling station 309 are provided with clamping members for clamping hardware parts.

[0025] The fixture in this embodiment consists of a housing 1, a mounting arm 2, a clamping structure, and a chip removal system 4. The mounting arm 2 is movably connected to the housing 1 and can rotate and be positioned with the support of the rotating base 102. The clamping mechanism 201 moves the screw 203 driven by a motor, thereby pushing the connecting clamping parts 303 (first clamping block 304 and second clamping block 306) toward the workpiece to clamp it firmly, thus fixing the hardware to the drilling station. During clamping, both the first drilling station 302 and the second drilling station are fixed with positioning blocks 305, which help ensure the accuracy of the workpiece position.

[0026] In this embodiment, a rotating base 102 is provided at the connection between the mounting arm 2 and the housing 1. The drive motor 101 provides power to rotate the mounting arm 2 clockwise along the axis of the rotating base 102. This allows the operator to flexibly adjust the processing position of the workpiece to adapt to different processing needs. Simultaneously, the dual-station design allows for drilling operations as needed, significantly improving processing efficiency. Its fixture structure ensures workpiece stability during drilling, thereby improving processing accuracy.

[0027] The chip removal system 4 includes a first high-pressure air pipe 402, a second high-pressure air pipe 403, and two independently configured control valves 401. The first high-pressure air pipe 402 and the second high-pressure air pipe 403 are connected to each of the control valves 401. The first high-pressure air pipe 402 is located on one side of the first drilling station 302, and the second high-pressure air pipe 403 is located on one side of the second drilling station 309.

[0028] In this embodiment, the chip removal system 4 blows chips out of the drilling station through a high-pressure air pipe, ensuring a clean working area. Simultaneously, two independently controlled valves precisely control the airflow, directionally blowing away chips to avoid affecting subsequent production processes. The high-pressure air pipes are strategically positioned next to the drilling station, facilitating the timely removal of evaporating cutting fluid and chips, reducing processing interference.

[0029] The height fine-tuning mechanism includes an adjustment seat, an adjustment motor 307 mounted on the adjustment seat, and an adjustment shaft 308. The adjustment seat is connected to a clamping member, and the adjustment shaft 308 is connected to the adjustment motor 307. The adjustment motor 307 is located at the bottom of the adjustment seat. The adjustment shaft 308 passes vertically through the adjustment seat and is connected to the clamping member. The clamping member moves along the axial direction of the adjustment shaft 308.

[0030] The height fine-tuning mechanism in this embodiment allows the operator to precisely adjust the position of the clamping component according to the requirements of the workpiece. The adjusting motor 307 drives the adjusting shaft 308 to move the clamping component in the vertical direction to accommodate different workpiece thicknesses.

[0031] In summary, this embodiment, through an effective clamping mechanism and the design of the positioning block 305, ensures that the workpiece remains firmly and accurately positioned during processing, reducing processing errors. The height fine-tuning and rotation functions give the equipment strong adaptability to workpieces of different sizes and shapes, meeting diverse processing needs. The effective cleaning of the chip removal system 4 improves processing continuity, reduces production disruptions caused by chip accumulation, and thus enhances work efficiency.

[0032] Furthermore, a rotating seat 102 is provided at the connection between the mounting arm 2 and the chassis 1. The chassis 1 is also provided with a drive motor 101 connected to the rotating seat 102. The rotating seat 102 is fixedly connected to the mounting arm 2, and the drive motor 101 is drivenly connected to the rotating seat 102. The mounting arm 2 rotates clockwise along the axis of the rotating seat 102.

[0033] The rotary base 102, as a key component connecting the mounting arm 2 and the housing 1, allows the mounting arm 2 to rotate around its central axis. It provides the necessary space for the mounting arm 2 to move in different working positions. The drive motor 101 is fixed to the housing 1 and connected to the rotary base 102 via a transmission mechanism (such as gears, pulleys, or chains). When the drive motor 101 operates, the driving force is transmitted to the rotary base 102 through the transmission system, causing it to rotate. Since the rotary base 102 is fixedly connected to the mounting arm 2, the mounting arm 2 rotates simultaneously with the rotary base 102. Specifically, the mounting arm 2 can move clockwise along the axis of the rotary base 102. This design allows workpieces to be processed more easily at different angles without requiring repositioning of the entire housing 1.

[0034] Furthermore, the clamping mechanism 201 includes a mounting base 202, a motor mounted on the mounting base 202, and a screw 203 connected to the motor. A plurality of connecting blocks 204 connecting the clamping members 303 are sleeved on the screw 203. The connecting blocks 204 are fixedly connected to the clamping members 303, and the clamping members 303 can move along the axial direction of the screw 203 through the connecting blocks 204.

[0035] When the motor starts, the clamping member 303 moves downwards or upwards. According to the design of the clamping mechanism 201, the clamping member 303 eventually contacts the workpiece, ensuring the workpiece is firmly clamped. Specifically, the rotation of the drive screw 203 (connected by gears or a belt) causes the connecting block 204, which is sleeved on it, to move along the axis of the screw 203. Since the connecting block 204 is fixedly connected to the clamping member 303, the clamping member 303 moves together with the connecting block 204. Specifically, by adjusting the rotation direction and speed of the motor, the clamping member 303 can be quickly clamped and released to adapt to the fixing requirements of different workpieces.

[0036] Furthermore, the clamping member 303 includes a first clamping block 304 and a second clamping block 306. Both the first drilling station 302 and the second drilling station 309 are provided with positioning blocks 305, wherein the positioning blocks 305 are disposed between the first clamping block 304 and the second clamping block 306.

[0037] When the hardware part is placed in the first or second drilling station 309, the first clamping block 304 and the second clamping block 306 will move closer to clamp the hardware part. The positioning block 305 between the clamping blocks ensures uniform clamping force, preventing workpiece tilting or displacement, thereby improving machining accuracy. The clamping and releasing process is driven by a motor, making it efficient and reliable. Employing dual-station machining, this structure allows for multiple machining operations on the same machine, offering strong adaptability and enabling the handling of hardware parts of various shapes and sizes.

[0038] To further explain, the first drilling station 302 is located at the upper end of the mounting arm 2, the second drilling station 309 is located at the lower end of the mounting arm 2, and the control valve 401 is symmetrically arranged on both sides of the mounting arm 2.

[0039] Two sets of high-pressure air pipes are each connected to an independent control valve 401, providing high-pressure airflow to remove chips generated during workpiece machining. Each control valve 401 controls the airflow of one set of high-pressure air pipes and can be opened and closed independently. When chips need to be removed during drilling operations, the airflow can be adjusted using the control valve 401.

[0040] To further explain, there are four high-pressure air pipes 402 and two high-pressure air pipes 403. The first high-pressure air pipes 402 are arranged in a straight line on one side of the first drilling station 302, and the second high-pressure air pipes 403 are arranged in a straight line on one side of the second drilling station 309.

[0041] The first drilling station 302 is also provided with a nozzle one for connecting the first high-pressure air pipe 402 on one side, and the second drilling station 309 is also provided with a nozzle two for connecting the second high-pressure air pipe 403 on one side.

[0042] During drilling, the generated chips accumulate in the correct location on the hardware in a non-contact manner. During operation, the corresponding air pipe can be opened via control valve 401 as needed. Airflow is ejected from nozzle one or nozzle two, forming a high-pressure airflow that promptly blows the chips away from the drilling station. The nozzle design ensures precise airflow guidance and facilitates effective airflow diffusion within the working area. Multiple air pipes on each station side effectively increase the quantity and intensity of airflow, accelerating chip removal. The linear arrangement ensures even airflow distribution, preventing uneven results caused by concentrated airflow at a single point.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
