It is suitable for the efficient and precision manufacturing of small and medium-sized parts and has the advantages of compact structure, high machining accuracy and automation integration. It is used in mold manufacturing, aerospace and automotive parts manufacturing.

[0003] Existing vertical machining centers for drilling parts consist of a machine body, a drive assembly, a transmission assembly, a drilling assembly, and a clamping assembly. In use, the parts to be drilled are placed in the clamping assembly, and the drive assembly and transmission assembly drive the drilling assembly to drill the parts. However, during the drilling process, existing vertical machining centers generally use the method of rotating the drilling assembly to adjust the position and direction of the drilling, which can only meet the requirement of drilling on one side of the parts and cannot drill on multiple sides of the parts. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical machining center with an auxiliary flipping structure to solve the problem mentioned in the background art that the existing vertical machining centers adjust the position and direction of drilling by driving the drilling assembly to rotate, which can only achieve single-sided drilling of parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical machining center with an auxiliary flipping structure, comprising a vertical machining center body, a drill rod and a mounting frame, wherein an electric push rod is provided at the top of the vertical machining center body, a drive motor is connected to the bottom of the electric push rod, and the output end of the drive motor is connected to the drill rod through a coupling;

[0006] The bottom of the drill rod is provided with an installation frame and a stepper motor. Transmission gear blocks are equidistantly connected to the outside of the installation frame. The outside of the transmission gear blocks meshes with the drive gear. The output end of the stepper motor is connected to the drive gear through a coupling. A guide groove is provided inside the installation frame. The bottom of the guide groove is inserted into the guide rail. A connecting ball is connected to the upper side of the guide rail. The connecting ball is slidably connected to the guide groove.

[0007] Preferably, the bottom of the guide rail is connected to the body of the vertical machining center, and both the mounting frame and the guide groove are arc-shaped.

[0008] Preferably, the mounting frame is provided with a first clamping plate and a second clamping plate, and an operation screen is installed on one side of the vertical machining center body.

[0009] Preferably, one side of the first clamping plate is connected to the rotating rod, the outer side of the rotating rod is rotatably connected to the mounting frame, and a positioning plate is connected to the side of the rotating rod away from the first clamping plate.

[0010] Preferably, the positioning disk has equidistant positioning slots inside, and an electric telescopic rod is installed on the outside of the mounting frame, with a positioning block connected to the top of the electric telescopic rod.

[0011] Preferably, the outer side of the positioning block is inserted into the positioning groove at the bottom of the positioning disk, and an electric telescopic rod is installed on the side of the mounting frame away from the positioning block.

[0012] Preferably, one end of the electric telescopic rod is connected to a servo motor, and the output end of the servo motor is connected to the second clamping plate via a coupling.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This vertical machining center with an auxiliary flipping structure can drive the parts to flip to a vertical position for drilling through the mounting frame, effectively expanding the processing range of the parts by the vertical machining center body. Furthermore, the parts can be flipped again through the first clamping plate, the second clamping plate, and the servo motor, which can further expand the processing range of the parts. This solves the problem that existing vertical machining centers can only achieve single-sided drilling of parts by adjusting the position and direction of drilling by driving the drilling assembly to rotate.

[0014] 1. This vertical machining center with an auxiliary flipping structure facilitates the smooth flipping of parts. Commands are issued via the control panel to activate a stepper motor installed inside the machining center body. The output of the stepper motor drives a drive gear to rotate via a coupling. When the drive gear rotates, its outer side meshes with transmission gears equidistantly positioned at the bottom of the mounting frame. This causes the mounting frame to flip, driven by the sliding action of the guide groove, guide rail, and connecting ball, thus flipping the parts inside the mounting frame. This vertical machining center with an auxiliary flipping structure allows parts to be flipped to a vertical position for drilling operations, effectively expanding the machining range of the vertical machining center body and improving machining efficiency.

[0015] 2. This vertical machining center with an auxiliary flipping structure, in order to further assist in flipping the parts, activates the electric telescopic rod to move the upper-connected positioning block downwards until it disengages from the positioning groove inside the positioning plate. At this time, the servo motor is activated, and the output end of the servo motor drives the second clamping plate connected to it to flip through the coupling. At this time, the second clamping plate can drive the parts, as well as the first clamping plate on one side of the parts, to flip smoothly under the action of the rotating rod and the mounting frame. This vertical machining center with an auxiliary flipping structure can drive the parts to flip again through the first clamping plate, the second clamping plate and the servo motor, further expanding the machinable range of the parts.

[0022] 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.

[0023] Please see Figures 1-5This utility model provides a technical solution: a vertical machining center with an auxiliary flipping structure, including a vertical machining center body 1, a drill rod 202 and a mounting frame 3. An electric push rod 2 is provided on the top of the vertical machining center body 1, and a drive motor 201 is connected to the bottom of the electric push rod 2. The output end of the drive motor 201 is connected to the drill rod 202 through a coupling.

[0024] The bottom of the drill rod 202 is provided with a mounting frame 3 and a stepper motor 303. Transmission gear blocks 301 are equidistantly connected to the outside of the mounting frame 3. The outside of the transmission gear blocks 301 meshes with the drive gear 302. The output end of the stepper motor 303 is connected to the drive gear 302 through a coupling. A guide groove 304 is provided inside the mounting frame 3. The bottom of the guide groove 304 is inserted into the guide rail 305. A connecting ball 306 is connected to the upper side of the guide rail 305. The connecting ball 306 is slidably connected to the guide groove 304. The bottom of the guide rail 305 is connected to the vertical machining center body 1. Both the mounting frame 3 and the guide groove 304 are arc-shaped. The mounting frame 3 is provided with a first clamping plate 4 and a second clamping plate 5. An operation screen 101 is installed on one side of the vertical machining center body 1.

[0025] In practice, to facilitate the smooth rotation of parts, a command is issued through the operation screen 101 to start the stepper motor 303 installed inside the vertical machining center body 1. The output end of the stepper motor 303 drives the drive gear 302 to rotate through the coupling. When the drive gear 302 rotates, its outer side meshes with the transmission teeth 301 equidistantly arranged at the bottom of the mounting frame 3. Under the sliding action of the guide groove 304, guide rail 305 and connecting ball 306, the parts clamped by the first clamping plate 4 and the second clamping plate 5 on the inner side of the mounting frame 3 can be gradually rotated. The connecting ball 306 is set for the rotational installation of the mounting frame 3 and provides guidance for the movement of the mounting frame 3. This vertical machining center with an auxiliary rotation structure can drive the parts to rotate to a vertical position for drilling work through the mounting frame 3, effectively improving the processing range of the parts by the vertical machining center body 1 and improving processing efficiency.

[0026] See Figure 3 and Figure 4It can be seen that one side of the first clamping plate 4 is connected to the rotating rod 401, the outer side of the rotating rod 401 is rotatably connected to the mounting frame 3, and the side of the rotating rod 401 away from the first clamping plate 4 is connected to the positioning plate 402. The positioning plate 402 has positioning grooves 403 evenly spaced inside. An electric telescopic rod 405 is installed on the outer side of the mounting frame 3. The top of the electric telescopic rod 405 is connected to the positioning block 404. The outer side of the positioning block 404 is inserted into the positioning groove 403 at the bottom of the positioning plate 402. An electric telescopic rod 502 is installed on the side of the mounting frame 3 away from the positioning block 404. One end of the electric telescopic rod 502 is connected to the servo motor 501. The output end of the servo motor 501 is connected to the second clamping plate 5 through a coupling.

[0027] In specific implementation, to further assist in the flipping of the parts, the electric telescopic rod 405 connected to one side of the mounting frame 3 is activated. The electric telescopic rod 405 drives the positioning block 404 connected to the upper side to move downward until it disengages from the positioning groove 403 inside the positioning disk 402. At this time, the servo motor 501 at the second clamping plate 5 is activated. The output end of the servo motor 501 drives the second clamping plate 5 connected to it to flip through the coupling. At this time, the second clamping plate 5 can drive the parts and the first clamping plate 4 on one side of the parts to flip smoothly under the action of the rotating rod 401 and the mounting frame 3. After the flipping is completed, the electric telescopic rod 405 is activated again, which can drive the positioning block 404 to insert into the positioning groove 403 inside the positioning disk 402 again, limiting the position of the first clamping plate 4, the parts and the second clamping plate 5. This vertical machining center with an auxiliary flipping structure can drive the parts to flip again through the first clamping plate 4, the second clamping plate 5 and the servo motor 501, further expanding the machinable range of the parts.

[0028] In summary, when using this vertical machining center with an auxiliary flipping structure, the parts are placed on the first clamping plate 4. An instruction is issued via the operation screen 101 to activate the electric telescopic rod 502, which drives the servo motor 501 and the second clamping plate 5 to clamp the parts. After clamping, the electric push rod 2 is activated. The bottom of the electric push rod 2 drives the drive motor 201 downwards. Simultaneously, the drive motor 201 is activated, and its output end drives the drill rod 202 to rotate via a coupling, drilling holes in the clamped parts.
