[0040] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] like Figure 1 As shown, the utility model provides a CNC machine tool. The CNC machine tool provided by the utility model includes a casing and a processing platform 200 . The processing platform 200 is arranged in the casing and can process a workpiece 100 .

[0042] Existing CNC machine tools are usually equipped with automatic loading devices. First, the workpiece is placed on the transfer fixture of the automatic loading device, and then the workpiece is transferred to the processing platform to replace manual loading. However, the position of the transfer fixture is usually fixed. When the CNC machine tool processes products of different types or sizes, the internal processing platform may need to be replaced or repositioned, resulting in the inability to adaptively adjust the position of the transfer fixture, affecting the position accuracy of the automatic loading, and may even cause the workpiece to collide with the processing platform.

[0043] In order to solve the above problems, Figure 2-Figure 3 As shown, the automatic loading device provided by the utility model is used to load and unload the workpiece 100 on the processing platform 200. The automatic loading device includes a transfer fixture 1 and a transfer mechanism 2. The transfer fixture 1 is used to carry the workpiece 100, and the transfer fixture 1 is adjustable in position at the loading and unloading position. The operator can adaptively adjust the installation position of the transfer fixture 1 according to the position of the processing platform 200, so that the transfer fixture 1 is always aligned with the processing platform 200, thereby improving the position accuracy of the automatic loading and avoiding the workpiece 100 from being aligned with the processing platform 200. The transfer mechanism 2 includes a transfer component 21 and a gripping component 22, the gripping component 22 is used to grip or release the workpiece 100, the transfer component 21 is transmission-connected to the gripping component 22, so as to transfer the workpiece 100 between the transfer fixture 1 and the processing platform 200, and the gripping component 22 has an avoidance position away from the transfer fixture 1, thereby providing the operator with an operating space for placing the workpiece 100 on the transfer fixture 1 or removing the workpiece 100.

[0044] like Figure 5As shown, the transfer fixture 1 includes a base 11 and a loading platform 12, the loading platform 12 is arranged on the base 11, and the base 11 can adjust the position of the loading platform 12 in the X-axis, Y-axis or Z-axis direction, wherein the X-axis is the length direction of the CNC machine tool, the Y-axis is the width direction of the CNC machine tool, and the Z-axis is the height direction of the CNC machine tool, and the X-axis, Y-axis and Z-axis are perpendicular to each other. When the position of the processing platform 200 changes, the position of the loading platform 12 in the X-axis or Y-axis direction can be adjusted so that the loading platform 12 is always aligned with the processing platform 200, thereby improving the position accuracy of automatic loading; the position of the loading platform 12 in the Z-axis direction can also be adjusted so that the loading platform 12 is always in line with the height of the processing platform 200, thereby reducing the moving distance of the grabbing component 22 in the Z-axis direction and improving the efficiency of loading and unloading. The above-mentioned setting simplifies the operation steps of adjusting the position of the transfer fixture 1, so that the transfer fixture 1 can be applied to different CNC machine tools, and improves the versatility of the automatic loading device.

[0045] Furthermore, the base 11 includes a first bracket 111, a cross frame 112 and a second bracket 113. The cross frame 112 is mounted on the first bracket 111 in an adjustable position along the Y-axis direction; one end of the second bracket 113 is mounted on the cross frame 112 in an adjustable position along the Z-axis direction; and the loading platform 12 is mounted on the other end relative to the second bracket 113 in an adjustable position along the X-axis direction. The above arrangement enables the base 11 to conveniently adjust the position of the loading platform 12 in the X-axis, Y-axis or Z-axis directions. Optionally, the above connections are all detachable connections. When the first bracket 111, the cross frame 112, the second bracket 113 or the loading platform 12 is damaged, it can be easily replaced, which is conducive to reducing maintenance costs. The operator can also replace the loading platform 12 adapted to the workpiece 100 of different sizes and shapes, further improving the versatility of the transfer fixture 1.

[0046] Specifically, the second bracket 113 is provided with a plurality of waist-shaped holes distributed along the Z-axis direction, and the waist-shaped holes extend along the Z-axis direction. The operator selects waist-shaped holes of appropriate height according to the position of the processing platform 200, and the bolts pass through the waist-shaped holes to connect the second bracket 113 with the cross frame 112. At this time, the bolts and nuts are not tightened, and the bolts can move in the waist-shaped holes along the Z-axis direction. The second bracket 113 can be moved to fine-tune the position of the second bracket 113 relative to the cross frame 112 along the Z-axis direction, and then the bolts and nuts are locked to lock the position of the second bracket 113 in the Z-axis direction, so as to realize the position adjustment of the loading platform 12 along the Z-axis direction. It should be noted that a waist-shaped hole extending along the Y-axis direction is provided on the horizontal frame 112, and a waist-shaped hole extending along the X-axis direction is provided at the end of the second bracket 113 close to the loading platform 12, so that the position adjustment method of the loading platform 12 along the X-axis direction and the Y-axis direction is the same as the position adjustment method along the Z-axis direction, and the position adjustment of the loading platform 12 along the X-axis direction and the Y-axis direction will not be repeated here.

[0047] In order to improve the positioning accuracy of the transfer fixture 1, a plurality of guide positioning blocks 13 are arranged circumferentially on the carrier platform 12 to circumferentially limit the position of the workpiece 100 located on the carrier platform 12 to improve the positioning accuracy of the workpiece 100, thereby avoiding collision between the transfer mechanism 2 and the processing platform 200 when transferring the workpiece 100.

[0048] Optionally, at least part of the guide positioning blocks 13 are installed on the loading platform 12 in an adjustable position, so that multiple guide positioning blocks 13 are matched with the workpiece 100, so that the transfer fixture 1 can be applied to workpieces 100 of different sizes, further improving its versatility. In this embodiment, the loading platform 12 is roughly rectangular, and multiple guide positioning blocks 13 are arranged at intervals along the circumference of the loading platform 12, so that the multiple guide positioning blocks 13 can enclose a limit space that matches the circumferential size of the workpiece 100. In order to adapt to workpieces 100 of different sizes, the guide positioning blocks 13 located on two adjacent sides of the loading platform 12 are movable positioning blocks, and the guide positioning blocks 13 located on the other two adjacent sides of the loading platform 12 are fixed positioning blocks. By adjusting the position of the movable positioning blocks, the movable positioning blocks and the fixed positioning blocks enclose limit spaces of different sizes to improve the versatility of the guide positioning blocks 13. The above-mentioned movable positioning blocks can be installed on the circumferential side of the loading platform 12 by means of springs and other components to achieve position adjustment of the movable positioning blocks. In other embodiments, all the guide positioning blocks 13 may be configured as movable positioning blocks.

[0049] Furthermore, the guide positioning block 13 is provided with a slope approaching from top to bottom toward the inside of the loading platform 12 , so as to guide the workpiece 100 to reach the surface of the loading platform 12 .

[0050] Optionally, the guide positioning block 13 is made of a material with relatively low hardness, including but not limited to aluminum, copper or plastic, so as to prevent the workpiece 100 from being damaged when friction or collision occurs between the workpiece 100 and the guide positioning block 13 .

[0051] In the present embodiment, a first positioning block 15 is also provided on the loading platform 12. The first positioning block 15 is used to carry the workpiece 100 to prevent the workpiece 100 from colliding with the loading platform 12. In addition, by providing the first positioning block 15, the contact area between the workpiece 100 and the transfer fixture 1 can be reduced, thereby reducing the possibility of wear on the surface of the workpiece 100. Furthermore, the first positioning block 15 is also made of a material with lower hardness, including but not limited to aluminum, copper or plastic, to prevent damage to the workpiece 100 when the workpiece 100 rubs or collides with the first positioning block 15. In the present embodiment, the number of the first positioning blocks 15 is four, and the four first positioning blocks 15 are distributed in a rectangular or array shape to jointly support the workpiece 100, thereby improving the stability and support strength of the workpiece 100.

[0052] Since the product has an installation direction, an anti-foolproof block 14 is also provided on the loading platform 12, and a groove that is plugged into the anti-foolproof block 14 is provided on the workpiece 100, so that the operator can easily determine the installation direction of the product when placing the workpiece 100 on the transfer fixture 1.

[0053] like Figure 3 As shown, the transfer component 21 includes a lifting component 211 and a transverse movement component 212. The output end of the lifting component 211 is connected to the grabbing component 22 to drive the grabbing component 22 to lift and move between the transfer fixture 1 and the processing platform 200. The output end of the transverse movement component 212 is connected to the lifting component 211 to drive the lifting component 211 and the grabbing component 22 to transfer between the transfer fixture 1 and the processing platform 200, so that the workpiece 100 can be transferred between the transfer fixture 1 and the processing platform 200 to realize automatic loading and unloading.

[0054] In order to adapt to the position of the transfer fixture 1 and the processing platform 200, the transverse movement assembly 212 includes a third bracket 2121, a fourth bracket 2122, a first connecting member 2123 and a transverse movement guide rail 2124. The fourth bracket 2122 is mounted on the third bracket 2121 in an adjustable position along the Z axis direction; the first connecting member 2123 is mounted on the fourth bracket 2122 in an adjustable position along the X axis direction; and the transverse movement guide rail 2124 is mounted on the first connecting member 2123 in an adjustable position along the Y axis direction. The above arrangement improves the mobility of the transverse movement assembly 212, and facilitates the adjustment of the position of the lifting assembly 211 in the X axis, Y axis or Z axis direction. Specifically, the fourth bracket 2122 is provided with a plurality of waist-shaped holes distributed along the Z-axis direction, and the waist-shaped holes extend along the Z-axis direction. The operator selects a waist-shaped hole of a suitable height according to the position of the processing platform 200, and the bolts pass through the waist-shaped holes to connect the fourth bracket 2122 with the third bracket 2121. At this time, the bolts and nuts are not tightened, and the bolts can move in the waist-shaped holes along the Z-axis direction. The fourth bracket 2122 can be moved to fine-tune the position of the fourth bracket 2122 relative to the third bracket 2121 along the Z-axis direction, and then the bolts and nuts are locked to lock the position of the fourth bracket 2122 in the Z-axis direction, so as to realize the position adjustment of the lifting assembly 211 along the Z-axis direction. It should be noted that a waist-shaped hole extending along the X-axis direction is provided at the end of the fourth bracket 2122 close to the first connecting member 2123, and a waist-shaped hole extending along the Y-axis direction is provided at the end of the first connecting member 2123 connected to the transverse guide rail 2124, so that the position adjustment method of the lifting component 211 along the X-axis direction and the Y-axis direction is the same as the position adjustment method along the Z-axis direction, and the position adjustment of the lifting component 211 along the X-axis direction and the Y-axis direction will not be repeated here.

[0055] Furthermore, if Figure 4 As shown, the gripping assembly 22 includes a mounting arm 221 and a plurality of suction cups 222. One end of the mounting arm 221 is transmission-connected to the lifting assembly 211. The plurality of suction cups 222 are arranged at the other end of the mounting arm 221 with adjustable spacing. Grasping or releasing the workpiece 100 by the suction cups 222 can avoid the gripping assembly 22 from causing damage to the workpiece 100. The operator can adjust the spacing between the suction cups 222 according to the size of the workpiece 100, so that the gripping assembly 22 can be applied to workpieces 100 of various sizes, further improving the versatility of the automatic loading device provided by the utility model. Specifically, a plurality of mounting positions are arranged on the mounting arm 221 along the X-axis direction and the Y-axis direction. The spacing between the plurality of suction cups 222 can be adjusted by arranging the suction cups 222 at different mounting positions. Optionally, the connection method between the suction cups 222 and the mounting arm 221 includes, but is not limited to, threaded connection or clamping.

[0057] In order to adapt to workpieces 100 of different thicknesses, the suction cup 222 can also adjust its position relative to the mounting arm 221 along the Z-axis direction, which is also beneficial for the operator to finely adjust the height of the suction cup 222 according to the height of the transfer fixture 1 and the processing platform 200, which is beneficial to improve positioning accuracy and versatility. Specifically, the suction cup 222 is threadedly connected to the mounting arm 221, and the position of the suction cup 222 in the Z-axis direction can be adjusted by rotating the suction cup 222.

[0058] like Figure 1 As shown, the CNC machine tool provided by the utility model can realize automatic loading and unloading of the workpiece 100 on the processing platform 200 by applying the above-mentioned automatic loading device, and can prevent the workpiece 100 from colliding with the processing platform 200.
