DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Example 1, reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, provides a multifunctional CNC machine tool that can realize two metal processing forms, milling and stamping, on a gantry CNC machine tool, such as Figure 1 As shown, it includes a crossbeam 100 arranged on the gantry of a CNC machine tool, and a guide rail 101 and a screw rod 102 are installed on one side of the crossbeam 100. Figure 4 As shown, the screw rod 102 is connected to the ball nut 103, and a transposition mechanism 200 is provided at the far end of the beam 100; Figure 3 As shown, the transposition mechanism 200 includes a flip cage 201, which is rectangular in shape. One end of the flip cage 201 is rotatably connected to the end surface of the beam 100, and the horizontal central axes of the flip cage 201 and the beam 100 are coaxial with the rotation axis of the flip cage 201. The upper and lower edges of both sides of the flip cage 201 are fixed with guide rails 202, and both sides of the flip cage 201 are slidably connected with slides 203 through the guide rails 202. Both sides of the flip cage 201 are provided with docking components 300; Figure 4 and Figure 5 As shown, the docking assembly 300 includes a cylinder 301 fixedly connected to the side wall of the flip cage 201, the output shaft of the cylinder 301 is fixedly connected to a sleeve 1 302, a sleeve 2 303 is inserted into the end of the sleeve 1 302, an annular electromagnet 304 is fixedly sleeved on the outside of the end of the sleeve 1 302, and a spring 1 305 is arranged in the sleeve 1 302 between the cylinder 301 and the sleeve 1 302, a spring 2 306 is sleeved between the inner wall of the electromagnet 304 away from one end of the cylinder 301 and the outer wall of the sleeve 1 302, and the sleeve 2 303 is coaxial with the screw rod 102.

[0029] Specifically, Figure 2As shown, the cross beam 100 has a built-in motor 204, and the output shaft end of the motor 204 is equipped with a reducer 205, and the housing of the reducer 205 is fixedly connected to the cross beam 100, as shown in FIG. Figure 3 As shown, the turning cage 201 is hollowed out, and an X-shaped support beam 206 is provided inside the turning cage 201. A short shaft 207 is fixedly inserted at the middle cross position of the support beam 206. The short shaft 207 is coaxially connected to the output shaft of the reducer 205. Figure 6 As shown, the outer diameter of the second sleeve 303 matches the inner hole of the ball nut 103, and the screw rod 102 is located at one end of the second sleeve 303 and is machined with a cylindrical column head 102a, and the inner diameter of the second sleeve 303 matches the column head 102a. Figure 7 As shown, each slide 203 is equipped with a ball nut 103, and the outer wall of the ball nut 103 is fixedly connected to the slide 203 via a nut seat.

[0030] like Figure 1 As shown, the two slides 203 are respectively vertically fixed with the main shaft 104 motor and the punching cylinder 105 through the upper adapter plate 208, and the two slides 203 are slidingly matched with the guide rail 101. The end of the beam 100 away from the shifting mechanism 200 is provided with a motor 2 106 coaxially connected with the screw rod 102.

[0031] The present invention provides a multifunctional CNC machine tool. In order to realize two processing forms of milling and stamping of thin-plate metal parts, a transposition mechanism 200 capable of rotating and switching processing execution units (such as a milling spindle 104 and a stamping cylinder 105) is provided on the basis of a conventional CNC gantry machine tool, and a docking component 300 is provided to connect the processing execution unit with a traditional gantry drive system (guide rail 101, screw rod 102, ball nut 103, etc.) during the switching of the processing execution elements. When it is necessary to switch the processing form, the traditional gantry drive system will move the slide 203 and the processing execution unit to a position close to the transposition mechanism 200, and the docking component 300 will take over the slide 203 and pull it into the transposition mechanism 200, the transposition mechanism 200 will rotate and switch to the target processing execution unit, and then the docking component 300 will push the target processing execution unit into the traditional gantry drive system.

[0032] To achieve the above-mentioned objective functions, the present invention also involves the following technical details: First, it should be noted that the transposition mechanism 200 is installed at the end of the conventional gantry beam 100. Therefore, when the gantry of the present invention is processed, the working range of the slide 203 is limited to the range of the guide rail 101. The transposition mechanism 200 and the guide rail 202 are located outside the machine tool processing platform and are only used to switch different processing execution units, not to bear the load during machining; the motor 1 204 should adopt a stepper motor (the stepper motor is lower in cost than the servo motor and has a higher static torque), and the motor 2 106 can adopt a stepper type or a servo type; The shifting mechanism 200 uses a hollow cast aluminum turning cage 201, whose cubic peripheral wall and X-shaped support beam 206 provide four evenly distributed triangular structures, which makes the turning cage 201 light and has sufficient structural strength. The connection between the X-shaped support beam 206 and the four edges of the cubic peripheral wall makes the four edges of the turning cage 201 thickened for opening holes to assemble the guide rail 2 202 with greater force. The cross beam 100 of the gantry is generally made of cast iron, such as Figure 2 As shown, by utilizing this feature, by presetting a motor installation position inside one end of the gantry beam 100, and installing a motor 204 and a reducer 205, the beam 100 and the flip cage 201 can be assembled. The reducer 205 amplifies the torque of the motor 204 to drive the flip cage 201 to rotate, and at the same time, the static torque of the motor 204 is sufficient to have sufficient resistance to external interference when the flip cage 201 is stationary. Therefore, no additional structure is required for locking, which simplifies the equipment structure. Figure 3 As shown, the reducer 205 can replace the output shaft of the motor 1 204 to connect the relatively thicker short shaft 207, thereby ensuring the structural rigidity (referring to the bending rigidity of the rotating shaft) between the flip cage 201 and the crossbeam 100; Secondly, conventional gantry CNC equipment generally adopts a screw 102 guide rail structure as the driving form, and the high-precision screw 102 and guide rail (C5 standard or higher level C3 standard) are very expensive, accounting for a high proportion of the hardware cost of the entire CNC machine tool. Therefore, the present invention does not use a set of screws 102 guide rails on both sides of the crossbeam 100 to simply and crudely realize the operation of two metal processing forms, but adopts a flip cage 201 to flip and switch different processing execution units to realize different processing forms. The transposition mechanism 200 is simple and compact and can significantly reduce the hardware cost, but its technical difficulties are: first, the screw 102 The BF end (the end away from the motor 106) needs a special support seat to assist the end of the screw rod 102 to rotate stably, but the use of the BF support seat will cause the slide 203 to be unable to move between the beam 100 and the transposition mechanism 200. Secondly, there are three main problems after the ball nut 103 on the slide 203 is separated from the screw rod 102: how to move the slide 203 to the target position of the flip cage 201 after losing the drive of the screw rod 102, how to prevent the steel column in the ball nut 103 from falling off after losing the holding effect of the screw rod 102, and how the internal steel ball of the ball nut 103 connects with the spiral groove of the screw rod 102 when the ball nut 103 is repeatedly assembled with the screw rod 102; refer to Figure 4 , the screw rod 102 first drives the ball nut 103 to move to the BF end of the screw rod 102. At this time, the nut has not yet separated from the screw rod 102, and the ball in the nut is supported by the screw rod 102. The cylinder 301 on the side wall of the flip cage 201 of the present invention pushes the sleeve 1 302 toward the screw rod 102, and the sleeve 2 303 inserted at the end of the sleeve 1 302 will be sleeved with the column head 102a at the end of the screw rod 102. After the sleeve 2 303 hits the end of the screw rod 102, the sleeve 1 302 compresses the spring 1 305 and continues to move toward the screw rod 102 until the working surface of the electromagnet 304 fits the ball nut 10 3 (compress spring 2 306 at the same time), at this time, the screw rod 102 continues to rotate to push the ball nut 103 toward the cylinder 301, the cylinder 301 is depressurized and the electromagnet 304 is energized to work and absorb the ball nut 103, the ball nut 103 fits the electromagnet 304 and enters the range of the sleeve 2 303 and separates from the screw rod 102, at this time, the ball in the ball nut 103 is supported by the sleeve 2 303 to prevent it from falling off, the cylinder 301 returns to the zero position, the ball nut 103 and the slide 203 enter the transposition mechanism 200, and at this time, the flip cage 201 can be rotated to switch the processing execution unit; When the ball nut 103 moves from the transposition mechanism 200 to the cross beam 100, the screw rod 102 needs to rotate at a low speed to actively connect with the ball nut 103. In addition, the pressure build-up of the cylinder 301 needs to be slow to avoid structural impact. Figure 6As shown, it is also necessary to first socket the second sleeve 303 with the stud 102a at the end of the lead screw 102, and then gradually reduce the voltage supply to the electromagnet 304, so that the magnetic attraction of the electromagnet 304 to the ball nut 103 gradually decreases, so that the release speed of the second spring 306 is controllable, so that the ball nut 103 combines with the lead screw 102 at a moving speed matching the rotation speed of the lead screw 102, so that the lead screw 102 can be smoothly screwed into the ball nut 103; When the ball nut 103 completely enters the lead screw 102, the ball nut 103, the slide table 203 mounted thereon, and the processing unit mounted on the slide table 203 can be used normally. At this time, the cylinder 301 does not need to retract, and the cylinder 301 needs to maintain the pressure building state. Since the BF end of the lead screw 102 of the present invention cancels the conventional BF support seat, at this time, the second sleeve 303, the first sleeve 302, and the cylinder 301 play a stabilizing role equivalent to that of the support seat for the BF end of the lead screw 102.

[0033] In summary, the multi-functional numerical control machine tool of the present invention utilizes the flexibility of the casting design of the gantry beam 100. By adding a numerically controlled rotating conversion mechanism 200 to the end of the conventional gantry beam 100, for thin metal sheets, different processing execution units can be flexibly switched to perform different forms of processing on the metal thin sheet. The docking assembly 300 therein is combined with the lead screw 102 in the traditional gantry drive system, which can not only flexibly and conveniently control the movement of the slide table 203 between the gantry beam 100 and the conversion mechanism 200, but also provide stable support for the lead screw 102.

[0034] Example 2, refer to Figure 7~Figure 8 , which is the second embodiment of the present invention. This embodiment provides a slide table 203 and an adapter plate 208 of a multi-functional numerical control machine tool. By using more adapter plates 208 to assemble different processing execution units, the functional expansion of the machine tool can be realized through the quick disassembly and assembly between the slide table 203 and the adapter plate 208. It includes a slide table 203. The slide table 203 is provided with a T-shaped groove 203a on the side close to the flipping cage 201. And the slide table 203 is provided with positioning sleeves 203b inserted through in the four short-sided grooves on both sides of the T-shape of the groove 203a. And each positioning sleeve 203b is inserted with a pin 203c along its radial direction. The pin 203c is slidably connected with the groove 203a in a matching manner. A third spring 203d is pre-pressed between two adjacent pins 203c. The slide table 203 covers the groove 203a and is hermetically provided with a T-shaped cover plate 203e. And the cover plate 203e is fitted with the slide table 203. The edge of the slide table 203 is provided with an air joint 203f. And the air joint 203f is communicated with the top of the T-shape of the groove 203a, as Figure 8As shown, an adapter plate 208 is provided on one side of the slide 203 away from the flip cage 201, and each positioning sleeve 203b is matched and plugged with a positioning pin 208a, the positioning pins 208a are vertically fixedly connected to the adapter plate 208, and adjacent positioning pins 208a and plugs 203c are matched and plugged.

[0035] by Fig. 9 Taking the perspective as an example, a groove 203a is machined on the side wall of the slide 203 and a cover plate 203e is sealed and installed, an air channel is established on the inner wall of the slide 203, which also serves as a sliding guide for the pin 203c. A threaded hole is machined on the top of the slide 203 to connect the groove 203a and an air joint 203f is installed. Negative pressure is drawn through the air joint 203f to control the two pins 203c on the same axis to move toward each other, and they are pulled out from the positioning sleeve 203b and the positioning pin 208a, thereby unlocking the adapter plate 208 from the slide 203. If the negative pressure is disconnected, the pin 203c is pushed into the positioning sleeve 203b and the positioning pin 208a under the reset of the spring three 203d to normally lock the slide 203 and the adapter plate 208.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
