Detailed Implementation

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Please see Figure 1-4 This utility model provides a four-spindle parallel inverted machining special machine, including a base 1, a support beam 10 is provided on the base 1, a clamp 11 for holding the product 100 is provided on the support beam 10, and a tool magazine 12 is symmetrically provided at both ends of the base 1.

[0026] Tool magazine 2, the tool magazine 2 are symmetrically arranged on the tool magazine frame 12, and each tool magazine 2 is provided with at least one tool 20;

[0027] The first driving device 3 has four parallel driving devices arranged between the tool magazine holder 12, and the driving directions are alternately and symmetrically arranged.

[0028] The processing device 4 includes a slide plate 40 movably mounted on each of the first drive devices 4, an extension frame 41 movably mounted on the slide plate 40, a second drive device 42 mounted on the slide plate 40 for driving the extension frame 41 to move closer to or away from the tool magazine 2, a Z-axis spindle motor 43 movably mounted on the side of the extension frame 41 closer to the tool magazine 2, a third drive device 44 mounted on the extension frame 41 for driving the Z-axis spindle motor 43 to rise or fall, and a tool holder 45 mounted at one end of the Z-axis spindle motor 43, wherein the Z-axis spindle motor 43 is inverted so that the tool holder 45 at one end faces upward.

[0029] In the above structure, the operator places the product in the tool holder position, and the product is clamped and fixed by the fixture. Four first drive units are arranged side-by-side, with alternating symmetrical driving directions. The two outermost first drive units have the same driving direction and both move the slide plate mounted on them to the left tool magazine position. The two inner first drive units have the same driving direction and both move the slide plate mounted on them to the right tool magazine position. The second drive unit drives the extension frame closer to the tool magazine, and the third drive unit drives the Z-axis spindle motor to move to the designated position, causing the extension frame to move closer to the tool magazine. The Z-axis spindle motor and tool holder are positioned close to the tool magazine for tool replacement or installation. The tool is then moved to the machining position via a first, second, and third drive unit. The Z-axis spindle motor drives the tool to process the product. The integrated system combines four spindle machining centers to simultaneously machine the product, significantly improving the machine's efficiency. Furthermore, the use of a first drive unit with alternating directional symmetry, in conjunction with the second and third drive units, allows the machining center to flexibly configure its working mode to suit different products and processing requirements.

[0030] Specifically, the support beams 10 are provided in six sections and are symmetrically arranged at both ends of the base 1. The symmetrical arrangement of the support beams can increase the aesthetics and make the visual effect less abrupt. At the same time, the symmetrical arrangement of the support beams can increase the stability of the clamps installed on them.

[0031] Specifically, the base 1 is covered with a machine tool sheet metal housing cover 13. The machine tool sheet metal housing cover can prevent operators from directly touching the running processing machine, protecting the personal safety of the operators, and can also protect the internal processing machine, preventing damage to the processing machine.

[0032] Specifically, the base 1 has a chip removal cart 14, a chip removal machine 15 that works with the chip removal cart 14, a hydraulic station 16 and an oil cooler 17 integrated on its side. The integrated design can reduce the space occupied by the overall device, while improving the utilization rate of each piece of equipment and reducing equipment investment and maintenance costs.

[0033] Specifically, the first driving device 3 includes a first servo motor 30 fixedly mounted on the base 1, a first lead screw 31 connected to one end of the first servo motor 30, a first nut 32 sleeved on the first lead screw 31, a first guide rail 33 parallel to both ends of the first lead screw 31, and a first slider 34 movably mounted on the first guide rail 33. The top ends of the first nut 32 and the first slider 34 are connected to the slide plate 40. When the first servo motor rotates, it drives the first lead screw connected to one side to rotate synchronously. The first nut converts the rotational motion of the first lead screw into linear motion, thereby driving the slide plate connected to it to move synchronously. The cooperation between the first slider and the first guide rail connected to the slide plate reduces the friction of the slide plate movement and guides the movement of the slide plate.

[0034] Specifically, the second drive device 42 includes a second servo motor 420 fixedly mounted on the slide plate 40, a second lead screw 421 connected to one end of the second servo motor 420, a second nut 422 sleeved on the second lead screw 421, a second guide rail 423 parallel to both ends of the second lead screw 421, and a second slider 424 movably mounted on the second guide rail 423. The top ends of the second nut 422 and the second slider 424 are connected to the riser frame 41. When the second servo motor rotates, it drives the second lead screw connected to one side to rotate synchronously. The second nut converts the rotational motion of the second lead screw into linear motion, thereby driving the riser frame connected to it to move synchronously. The cooperation between the second slider and the second guide rail connected to the riser frame reduces the friction of the riser frame movement and guides the movement of the riser frame.

[0035] Specifically, the third drive device 44 includes a third servo motor 440 fixedly mounted on the riser frame 41, a third lead screw 441 connected to one end of the third servo motor 440, a third nut 442 sleeved on the third lead screw 441, a third guide rail 443 parallel to both ends of the third lead screw 441, and a third slider 444 movably mounted on the third guide rail 443. The top ends of the third nut 442 and the third slider 444 are connected to the Z-axis spindle motor 43. When the third servo motor rotates, it drives the third lead screw connected to one side to rotate synchronously. The third nut converts the rotational motion of the third lead screw into linear motion, thereby driving the Z-axis spindle motor connected to it to move synchronously. The cooperation between the third slider and the third guide rail connected to the Z-axis spindle motor reduces the friction of the Z-axis spindle motor movement and guides the movement of the Z-axis spindle motor.

[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
