[0002] As a core component for realizing the rotational movement of mechanical components, the electric shaft has been widely used in fields such as electronic devices and automotive parts. In computer accessories, the electric shaft is commonly used in adjustable structures such as monitor brackets and keyboard trays. In automotive seat electronic screens, the electric shaft is a key accessory for support and angle adjustment to ensure stable display and precise control of the screen during driving.

[0003] The patent application with the application number CN103521811A discloses a PCB board drilling fixture, which includes a fixture substrate. On the fixture substrate, there are symmetrically distributed fixing seats for fixing the PCB board to be drilled. On the outside of the two fixing seats on the fixture substrate, there is a fixing shaft respectively. A drilling board is installed between the two fixing shafts. One side of the drilling board rotates along the straight line formed by the two fixing shafts and is clamped above the two fixing seats. On the upper surface of the drilling board, there are distributed a plurality of drilling sleeves corresponding to the drilling positions of the PCB board to be drilled. The PCB board drilling fixture of the present invention can accurately position the PCB board, has high drilling accuracy, is convenient for secondary drilling processing of the PCB board, installs the PCB board into the product housing for testing, has a simple structure, is easy to implement, and has good application prospects.

Conventional clamping mechanisms cannot adapt to the special-shaped contour of the housing, resulting in repeated adjustment and alignment during the clamping process, and the insufficient fixing stability is prone to cause displacement deviation during processing, affecting the drilling accuracy and being unfavorable for the production needs of the equipment. Summary of the Invention

[0007] A drilling device for the housing of a zero-backlash electric rotating shaft with a clutch, including: a base, the top of the base is fixedly connected with a first moving device, the inner wall of the first moving device is movably connected with a third moving device, the outer wall of the third moving device is movably connected with a first movable seat, the outer wall of the first movable seat is fixedly connected with a fourth moving device, the outer wall of the fourth moving device is movably connected with a drilling device, and the specific position of the drilling device is controlled by the first moving device, the third moving device and the fourth moving device.

[0008] According to the above technical solution, a groove is opened at the top of the base, a placement groove is opened on the inner wall of the groove, a second moving device is fixedly connected to the inner wall of the groove, and a rotating assembly is movably connected to the outer wall of the second moving device. The forward and backward movement of the rotating assembly is controlled by the second moving device.

[0009] According to the above technical solution, a first push rod is fixedly connected to the inner wall of the base, a support column is fixedly connected to the top of the first push rod, the support column penetrates through the base and extends into the groove, and the outer wall of the support column is movably connected to the base. This first push rod is used to control the height of the support column.

[0010] According to the above technical solution, the rotating assembly includes a second movable seat. The bottom of the second movable seat is movably connected. The top of the second movable seat is fixedly connected with a first connecting plate. The top of the second movable seat is fixedly connected with a second motor. One side of the first connecting plate away from the second motor is rotatably connected with a rotating plate through a bearing. The output end of the second motor is fixedly connected with the rotating plate. The outer wall of the rotating plate is fixedly connected with a third motor. The inner wall of the rotating plate is rotatably connected with a placing assembly through a bearing. The deflection angle of the placing assembly is controlled by the second motor and the third motor.

At the same time, the inclined station design makes the bottom plate also form an inclined state, improving the chip discharge efficiency, avoiding the accumulation problem of the traditional horizontal station, and improving the production efficiency.

The outer wall of the second connecting plate is rotatably connected with the rotating plate through a bearing.

At the same time, the hollow design eliminates the sudden change of cutting resistance that may be caused by the traditional solid support surface, making the drilling process smoother, improving the surface finish and perpendicularity of the housing hole. And the chips generated by processing can directly fall to the bottom plate through the through-hole at the bottom, facilitating the automatic discharge of the chips when the equipment is disassembled, and improving the production efficiency.

Without the complex fixing process of traditional fixtures, the initial positioning of the housing is directly completed, reducing the clamping time and improving the production efficiency.

[0014] Compared with the prior art, the present invention provides a zero-backlash electric rotating shaft with a clutch and a drilling device for a rotating shaft housing, having the following beneficial effects:

[0015] 1. By setting the placement component, with the limiting structure of the first convex plate and the second convex plate, the present invention realizes the rapid positioning and calibration of the housing based on the diagonal positioning principle. Without the complex fixing process of traditional fixtures, the initial positioning of the housing is directly completed, reducing the clamping time and improving the production efficiency.

[0016] 2. By setting the placement component, during the drilling operation of the device, the bottom through-hole structure can effectively prevent the drill bit from coming into hard contact with the support surface, eliminating the risk of drill bit chipping or wear, ensuring the machining accuracy of the hole diameter. At the same time, the hollow design eliminates the sudden change in cutting resistance that may be caused by the traditional solid support surface, making the drilling process smoother, improving the surface finish and perpendicularity of the housing opening. And the chips generated during processing can directly fall to the bottom plate through the bottom through-hole, facilitating the automatic discharge of the chips when the device is disassembled, and improving the production efficiency.

[0017] 3. By setting the placement component, the fixed plate structure can conform to the special-shaped contour of the housing, avoiding drilling deviation caused by fixing failure. At the same time, the fixed plate and the first and second convex plates form a triangular stable support structure, reducing the clamping steps compared with the traditional planar clamping. And this fixing method avoids local extrusion damage to the convex part during drilling, improving the production efficiency.

[0018] 4. By setting the rotating component, after the processing is completed, the rotating component automatically drives the placement component to deflect, making the first convex plate and the second convex plate at the low position end. Using gravity, the housing automatically slides into the bottom along the inclined plane, shortening the clamping time. At the same time, the inclined station design makes the bottom plate also form an inclined state, improving the chip discharge efficiency and avoiding the accumulation problem of the traditional horizontal station, and improving the production efficiency.
