DETAILED DESCRIPTION

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] See also Figure 1-2 As shown, in this embodiment, a high-rigidity extended-stroke CNC machine tool is provided, comprising: a frame 1, a rotating assembly and a resistance assembly are provided on the upper side of the frame 1, a power assembly corresponding to the rotating assembly is provided on the side of the frame 1, a Z-axis moving assembly is movably matched with the upper side of the frame 1, the rotating assembly and the resistance assembly are located on one side of the Z-axis moving assembly, an X-axis moving assembly is movably matched with the Z-axis moving assembly, a mounting seat 14 is provided on the X-axis moving assembly, the X-axis moving assembly is located between the rotating assembly and the resistance assembly, and a suitable processing tool or equipment can be installed on the upper side of the mounting seat 14 as required;

[0026] The rotating assembly includes an axle box 2 installed on the upper side of the frame 1, and a sleeve-type main shaft 201 is rotatably fitted in the axle box 2. The two ends of the sleeve-type main shaft 201 are respectively fixedly connected to a multi-groove pulley 202 and a chuck 203. The multi-groove pulley 202 and the circumferential side of the power assembly are provided with multiple belts 3.

[0027] One aspect of the application of this embodiment is as follows: during installation, the workpiece to be processed is placed between the rotating assembly and the interference assembly, and then the chuck 203 is used to clamp one end of the workpiece, and the interference assembly is used to interfere with the other end of the workpiece. During operation, the power assembly drives the multi-groove pulley 1 202 to rotate through the belt 3, and the rotation of the multi-groove pulley 1 202 drives the sleeve-type spindle 201 and the chuck 203 to rotate, thereby driving the workpiece to rotate. At the same time, the Z-axis moving assembly and the X-axis moving assembly can be controlled to flexibly adjust the position of the mounting base 14. It should be noted that all electrical equipment involved in this application can be powered by batteries or external power supplies.

[0028] The sleeve-type spindle 201 makes the rotation of the workpiece more stable during the processing, and is matched with the chuck 203 and the interference component to improve the finish, precision and stability of the product processing. The transmission is carried out through a multi-groove pulley 202 and multiple belts 3. While ensuring the transmission power, the diameter and width of the pulley can be relatively reduced, making the overall structure more compact and reducing the production and use costs. The cooperation of the Z-axis moving component and the X-axis moving component facilitates multi-directional adjustment of the mounting seat 14.

[0029] like Figure 1 As shown, the power component of this embodiment includes a servo motor 1 embedded in one side of the frame 1, the output shaft of the servo motor 1 is fixedly connected to the multi-groove pulley 2, the belt 3 is arranged on the circumference of the multi-groove pulley 1 202 and the multi-groove pulley 2, the multi-groove pulley 1 202, the multi-groove pulley 2 and the belt 3 are all located on the side of the frame 1, and the multi-groove pulley 2 is driven to rotate by the servo motor 1, thereby using the belt 3 to drive the multi-groove pulley 1 202 to rotate.

[0030] like Figure 1 As shown, two guide rails 6 are provided above the rack 1 of this embodiment, and multiple support blocks 601 are provided between the guide rails 6 and the rack 1. The interference assembly is slidably fitted on the two guide rails 6, and the guide rails 6 are raised by the support blocks 601, thereby reducing the probability of friction between the bottom of the interference assembly and metal debris falling on the rack 1 when the interference assembly is displaced.

[0031] like Figure 1 、 2 As shown, the interference assembly of this embodiment includes an electric slide 4 that is slidably fitted on two guide rails 6. A hydraulic tailstock 8 is installed on the upper side of the electric slide 4. The hydraulic tailstock 8 is used to interfere with the end of the workpiece, thereby improving the stability of the workpiece during rotation and the accuracy of processing.

[0032] like Figure 1 As shown, the Z-axis moving assembly of this embodiment includes a servo motor 2 5 and a Z-axis large slide 9. The servo motor 2 5 is installed on the upper side of the frame 1. The output shaft of the servo motor 2 5 is fixedly connected to a screw 1 501. A screw barrel 1 is provided under the Z-axis large slide 9 and is threadedly engaged with the side of the screw 1 501. The servo motor 2 5 drives the screw 1 501 to rotate, and the rotation of the screw 1 501 drives the screw barrel 1 and the Z-axis large slide 9 to slide.

[0033] like Figure 1 、 2 As shown, two guide rails 2 10 are installed on the upper side of the frame 1 of this embodiment, the servo motor 2 5 and the screw 1 501 are located between the two guide rails 2 10, and two slides 1 that slide in conjunction with the guide rails 2 10 are installed under the Z-axis large slide 9. The slide 1 slides in conjunction with the guide rails 2 10 to improve the stability of the Z-axis large slide 9 during sliding and reduce the probability of the screw barrel 1 shaking due to the rotation of the screw 1 501.

[0034] like Figure 1 、 2 As shown, the X-axis moving assembly of this embodiment includes a servo motor 3 11 and an X-axis middle carriage 12. The servo motor 3 11 is installed on the Z-axis large carriage 9. The output shaft of the servo motor 3 11 is fixedly connected to the lead screw 2 1101. A screw barrel 2 is provided below the X-axis middle carriage 12 and is threadedly engaged with the side of the lead screw 2 1101. The mounting seat 14 is installed on the X-axis middle carriage 12. The servo motor 3 11 drives the lead screw 2 1101 to rotate, and the rotation of the lead screw 2 1101 drives the screw barrel 2, the X-axis middle carriage 12 and the mounting seat 14 to slide.

[0035] like Figure 1 、 2 As shown, in this embodiment, two guide rails three 13 are installed on the large Z-axis carriage 9, the servo motor three 11 and the lead screw two 1101 are located between the two guide rails three 13, and two slide seats two that slide in conjunction with the guide rail three 13 are installed under the X-axis middle carriage 12.
