[0017] 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.

[0018] Please see Figures 1-2 In this embodiment of the utility model, a CNC Swiss-type lathe side milling transverse movement device includes a tool box 2, which serves as the basic component of the device and provides mounting support for other components. A limit block 1 is bolted to the front end of the tool box 2. The bottom width of the limit block 1 is greater than the side wall width of the tool box 2 and it is located in front of the electric spindle mounting base 4. It can block and limit the electric spindle mounting base 4 when it moves to the front limit position to prevent it from exceeding the predetermined range. The tool holder 2 has a sliding groove 16 on its side interior, and an electric spindle mounting seat 4 is provided on the side. The tool holder 2 has an insert 3 inside, and a dovetail boss is installed at one end of the electric spindle mounting seat 4. The width of the insert 3 is smaller than the width of the sliding groove 16 and the width of the dovetail boss. The electric spindle mounting seat 4 slides inside the sliding groove 16 through the cooperation of the dovetail boss and the insert 3. This structural design ensures the smoothness and accuracy of the sliding of the electric spindle mounting seat 4, while the insert 3 also plays the role of adjusting the tightness. An electric spindle 5 is bolted inside the electric spindle mounting base 4. A drill bit 17 is mounted on the lower end of the electric spindle 5. The electric spindle 5 can drive the drill bit 17 to rotate at high speed to achieve side milling of the parts. The other end of the tool box 2 is provided with a motor mounting base 7. A nut mounting base 6 is installed at one end of the electric spindle mounting base 4 and inside the motor mounting base 7. The nut mounting base 6 has an "L" shaped structure and is installed in a semi-enclosed manner around the electric spindle mounting base 4. It is fixedly connected to the electric spindle mounting base 4 by bolts. A stepper motor 11 is mounted on one end of the motor mounting base 7. A motor cover 12 is provided around the stepper motor 11. Both the stepper motor 11 and the motor cover 12 are fixedly connected to the side of the motor mounting base 7 by bolts. The motor cover 12 protects the stepper motor 11, preventing dust, impurities, etc., from entering the motor and affecting its normal operation. A connecting wire is provided on one side of the stepper motor 11 for connecting to an external control system and receiving control signals. One end of the stepper motor 11 is connected to a ball screw 13, and a screw nut 8 is fitted onto the ball screw 13. The motor mounting base 7 has a pre-drilled groove for the linear movement of the screw nut 8. The screw nut 8 passes through the motor mounting base 7 and is fixedly connected to the nut mounting base 6 by bolts. When the stepper motor 11 is working, it drives the ball screw 13 to rotate. The rotation of the ball screw 13, in turn, drives the screw nut 8 to move linearly along its axial direction. The screw nut 8 drives the nut mounting base 6 to move, thereby driving the electric spindle mounting base 4 to move laterally within the slide groove 16. An inductive proximity switch bracket 10 is provided on the outer side of the nut mounting base 6. An elliptical moving hole 14 is provided on the side of the inductive proximity switch bracket 10. An inductive proximity switch 9 is inserted through the elliptical moving hole 14. A limit adjustment ring 15 is provided in the middle of the inductive proximity switch 9, and the limit adjustment ring 15 is in rolling connection with the elliptical moving hole 14. The inductive proximity switch 9 is located on one side of the nut mounting base 6. The inductive proximity switch 9 can move within the elliptical moving hole 14. The inductive proximity switch 9 is a position sensor with a switching output. It detects the presence or absence of metal when a metal object approaches this oscillating sensing head that generates an electromagnetic field, thereby controlling the switch to open or close. When the proximity switch contact senses the position of the ball screw nut, the power supply to the stepper motor is cut off, and the stepper motor stops working. This position is used to set the stepper motor to return to its origin position. The feed stroke of the ball screw stepper motor can be set through the origin position to control the reciprocating position. The position is adjusted by the limit adjustment ring 15, which is used to control the movement position of the electric spindle mounting base 4 and achieve precise control of the device operation. The working process of this embodiment is as follows: When a side milling lateral movement operation is required, the external control system sends a control signal to the stepper motor 11 through the connecting wire. The stepper motor 11 starts and drives the ball screw 13 to rotate. The rotation of the ball screw 13 causes the screw nut 8 to move linearly in the groove inside the motor mounting seat 7. The screw nut 8 drives the nut mounting seat 6 to move. The nut mounting seat 6 then drives the electric spindle mounting seat 4 to slide in the slide groove 16 of the tool box 2 through the cooperation of the dovetail boss and the insert 3, realizing the lateral movement of the electric spindle 5 and the drill bit 17, thereby completing the lateral movement operation of the side milling. During the movement, the limiting block 1 plays a limiting role on the electric spindle mounting seat 4.
