[0013] Example 1: like Figure 1 and Figure 2As shown, an automatic beveling machine tool holder assembly includes a first tool holder 1, a first worm gear rotation device 2 for adjusting the cutting angle of the first tool holder 1, and a first base 51. The first worm gear rotation device 2 includes a first mounting plate 21, a rotary disk 23, and a first motor 24. The first mounting plate 21 is supported on the first base 51 by a tool holder displacement assembly. A worm gear driver 22 is fixedly connected to the side of the first mounting plate 21. The rotary disk 23 is mounted on the worm gear shaft of the worm gear driver 22, and the first tool holder 1 is mounted on the rotary disk 23. The first motor 24 is fixedly connected to the first mounting plate 21, and the shaft of the first motor 24 is connected to the worm shaft of the worm gear driver 22. The worm gear driver 22 is used as the main drive, and the first motor 24 drives the worm, which in turn drives the rotary disk 23 on the worm gear shaft to rotate, thereby realizing the angle adjustment of the first tool holder 1. The self-locking characteristic ensures angular stability during cutting. The arc-shaped guide rail 25 and the slider: The slider, which is fixed to the bottom of the worm gear driver 22, slides along the arc-shaped guide rail 25 on the mounting plate, which not only bears the cutting force but also ensures the accuracy of the movement trajectory of the rotary table 23. A linear drive module 6 is set between the first worm gear rotary device 2 and the first tool holder 1. One side of the linear drive module 6 is fixedly connected to the rotary table 23 of the first worm gear rotary device 2, and the slide of the linear drive module 6 is fixedly connected to the first tool holder 1. Based on the angle adjustment, the designed linear drive module 6 is supported by the rotary table 23 and pushes the first tool holder 1 to perform tool advance or retraction operations. There are two sets of first front-to-back displacement modules 3. Each set of first front-to-back displacement modules 3 is equipped with a first worm gear rotary device 2, and each first worm gear rotary device 2 is equipped with a first tool holder 1. The upper and lower sides of the circuit boards of the two first tool holders 1 can perform cutting operations simultaneously.

[0014] Example 2 Based on Example 1, such as Figure 3As shown, to facilitate the adjustment of the position (Y-axis direction) of the first worm gear rotation device 2, a first forward and backward displacement module 3 is designed. This first forward and backward displacement module 3 can drive the first worm gear rotation device 2 to move forward and backward (Y-axis direction). Its structure includes: a U-shaped bracket 31, a first linear guide rail 32, a second slider 33, a first ball screw 34, a first connecting piece 35, and a second motor 36. The connections of each component are as follows: the first linear guide rail 32 is fixedly connected to the U-shaped bracket 31; the second slider 33 slides with the first linear guide rail 32; the first slider 26 is fixedly connected to the first mounting plate 21; both ends of the first ball screw 34 are connected to the first mounting plate 21 through first bearings; one end of the second connecting piece 45 is fixedly connected to the U-shaped bracket 31; one end of the first connecting piece 35 is threaded with the first ball screw 34; the second motor 36 is fixedly connected to the first mounting plate 21; the shaft of the second motor 36 is connected to the third ball screw 54. The working principle of the first forward and backward displacement module 3 is as follows: Based on a precision linear motion structure using ball screw drive and linear guide rail, the second motor 36 (usually a servo motor or stepper motor) receives pulse signals from the control system and outputs rotational motion. The motor shaft is rigidly connected to the first ball screw 34 via a coupling, transmitting torque to the first ball screw 34. When the first ball screw 34 rotates, the first connecting piece 35 (which has a threaded hole or a ball nut installed on it and is threaded to the first ball screw 34) is constrained by the guide rail, converting the rotational motion into linear motion. The first linear guide rail 32 (fixed on the U-shaped bracket 31) and the second slider 33 form a sliding pair, restricting the degree of freedom of motion and ensuring that the first connecting piece 35 can only move along the Y-axis, eliminating offset and deflection in the X / Z directions. The first connecting piece 35 transmits linear thrust to the first mounting plate 21 through a rigid structure (such as an L-shaped bracket). The entire worm gear rotation device moves synchronously along the Y-axis with the mounting plate, achieving overall front-to-back displacement.

[0015] like Figure 4As shown, a first height adjustment module 4 is also designed to adjust the overall displacement along the Z-axis, thereby achieving the overall vertical displacement. The first height adjustment module 4 includes: an L-shaped bracket 41, a second linear guide rail 42, a third slider 43, a second ball screw 44, a second connector 45, and a third motor 46. The connections of each component are as follows: the second linear guide rail 42 is fixedly connected to the side of the L-shaped bracket 41; one end of the third slider 43 is slidably connected to the second linear guide rail 42, and the other end of the third slider 43 is fixedly connected to the U-shaped bracket 31; both ends of the second ball screw 44 are supported on the side of the L-shaped bracket 41 by second bearing components; the other end of the first connector 35 is fixedly connected to the side of the U-shaped bracket 31, and the other end of the second connector 45 is threadedly connected to the second ball screw 44; the third motor 46 is installed on the side of the L-shaped bracket 41, and the shaft of the third motor 46 is connected to the second ball screw 44. In use, the third motor 46 is supported by the L-shaped bracket 41. The shaft of the third motor 46 drives the second ball screw 44 to rotate. The second connecting piece 45 moves up and down along the surface of the second ball screw 44, causing the U-shaped bracket 31 to move up and down. The third slider 43 and the second linear guide rail 42 can constrain the U-shaped bracket 31 to move only vertically. A clamping cylinder 7 can also be installed on the L-shaped bracket 41. The piston rod of the clamping cylinder 7 is fixedly connected to the U-shaped bracket 31 through the bracket. The clamping cylinder 7 can assist the air pressure to push the U-shaped bracket 31 to move up and down, so as to reduce the load on the second ball screw 44.

[0016] like Figure 5As shown, a first left-right translation module 5 is also designed to adjust the overall displacement along the X-axis direction, thereby achieving the overall left-right displacement. The first left-right translation module 5 includes a first base 51, a third linear guide rail 52, a fourth slider 53, a third ball screw 54, a third connector 55, and a fourth motor 56. The connections of each component are as follows: the third linear guide rail 52 is fixedly connected to the first base 51; the fourth slider 53 is slidably connected to the third linear guide rail 52 and fixedly connected to the L-shaped bracket 41; both ends of the third ball screw 54 are fixedly connected to the first base 51 through the first bearing component; one end of the third connector 55 is connected to the third ball screw 54. The ball screw 54 is threaded, and the other end of the third connecting piece 55 is fixedly connected to the L-shaped bracket 41. The fourth motor 56 is mounted on the first base 51, and the shaft of the fourth motor 56 is fixedly connected to the third ball screw 54. The fourth motor 56 drives the third ball screw 54 to rotate. The third connecting piece 55 (fixed to the L-shaped bracket 41) moves along the X-axis under the guidance of the fourth slider 53 and the third linear guide rail 52. The third linear guide rail 52 restricts the Y / Z direction degrees of freedom to ensure pure X-axis translation. The L-shaped bracket 41 drives the first height adjustment module 4, the first front-to-back displacement module 3, and the first worm gear rotation device 2 to move left and right as a whole. In summary, when the X / Y axes are linked, the device moves diagonally in the horizontal plane. When the Z-axis is raised or lowered, the X / Y position is adjusted synchronously to realize three-dimensional path planning. After the three-axis modules are superimposed, spatial trajectory movement (such as oblique lines and arcs) can be realized, which satisfies the requirement that the first tool holder 1 is adjustable in three-dimensional space.
