Detailed implementation mode

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a horizontal CNC machining center ATC automatic tool changer, including a CNC machining table 1, a horizontal CNC table 2 is installed on one side of the top of the CNC machining table 1, and a tool holder 3 is arranged on one side of the horizontal CNC table 2. A original tool 4 is clamped at the center of one side of the tool holder 3, and a movable frame assembly 5 is arranged on one side of the top of the CNC machining table 1 close to the original tool 4;

[0023] The movable frame assembly 5 includes two chutes 504 that are parallelly opened on the top of the CNC machining table 1, and slide rails 502 are slidably installed inside the chutes 504. Electric telescopic rods 503 are installed on one side of each slide rail 502, and one end of each electric telescopic rod 503 is connected to the inner wall of the chute 504. The tops of the two slide rails 502 are connected with a U-shaped frame 501;

[0024] The U-shaped frame 501 and the CNC machining table 1 form a front-back sliding structure, and the U-shaped frame 501 is rotationally connected to a rotating cylinder 6 through a rotating shaft 12;

[0025] Specifically, as shown in Figure 1 、 Figure 2 , when in use, the electric telescopic rod 503 is used for telescoping to facilitate the adjustment of the position of the U-shaped frame 501. On the one hand, the U-shaped frame 501 can be placed at the tool replacement position, and on the other hand, after the tool replacement is completed, the U-shaped frame 501 is prevented from blocking the machining station of the original tool 4 to facilitate the machining operation of the workpiece;

[0026] And a motor 8 is installed at the top of one side of the movable frame assembly 5. The output end of the motor 8 is installed with a rotating shaft 12, and a rotating cylinder 6 is sleeved outside the rotating shaft 12. The cross section of the rotating cylinder 6 is square, and electromagnetic rails 10 are arranged on all four sides of the rotating cylinder 6;

[0027] The electromagnetic slider 11 slides along the inside of the electromagnetic rail 10, and the sliding direction of the electromagnetic slider 11 is parallel to the length direction of the original tool 4;

[0028] The single rotation angle of the rotating cylinder 6 is 90°. Electromagnetic sliders 11 are slidably installed inside the electromagnetic rails 10, and movable blocks 7 are installed at the outer ends of the electromagnetic sliders 11. Arc-shaped clamping plates 14 are installed on both sides of the outer end of the movable block 7.

[0029] There are four groups of arc-shaped clamping plates 14, and each group of arc-shaped clamping plates 14 has two. Anti-slip pads 15 are evenly installed on the opposite surfaces of each group of arc-shaped clamping plates 14, and three groups of arc-shaped clamping plates 14 away from the original tool 4 clamp the replacement tool 9.

[0030] Specifically, as Figure 1 、 Figure 3 and Figure 4 shown, when in use, the cooperation between the electromagnetic slider 11 and the electromagnetic rail 10 is utilized to facilitate the horizontal left-right adjustment of the position of the arc-shaped clamping plate 14, so as to facilitate the disassembly or installation operation of the originally clamped tool 4 or the replacement tool 9 by the arc-shaped clamping plate 14. The cooperation of multiple groups of arc-shaped clamping plates 14 is utilized to facilitate the pre-storage of the types of tools to be replaced, and to facilitate the storage of the replaced original tool 4.

[0031] Clamping adjustment mechanisms 13 are arranged inside the movable blocks 7 to control the opening and closing movement of the two arc-shaped clamping plates 14 on the same movable block 7.

[0032] The clamping adjustment mechanism 13 includes a cavity 1301 opened inside the movable block 7, and an electromagnet 1302 is installed at the center inside the cavity 1301. Metal sliding plates 1303 are slidably installed at both ends inside the cavity 1301, and L-shaped pressing plates 1304 are installed on the outer sides of the metal sliding plates 1303. The outer sides of the L-shaped pressing plates 1304 all penetrate to the outside of the movable block 7, and at the same time, the top ends of the outer sides of the L-shaped pressing plates 1304 always abut against the outer side walls of the arc-shaped clamping plates 14.

[0033] When the electromagnet 1302 is energized, both sides of the electromagnet 1302 are attached to the corresponding metal sliding plates 1303, so that the two arc-shaped clamping plates 14 are turned inward and close to each other.

[0034] Specifically, as Figure 1 、 Figure 4 shown, when in use, the electromagnetic property of the electromagnet 1302 is utilized to facilitate the adjustment of the position of the electromagnet 1302, so as to ensure that when clamping, the two arc-shaped clamping plates 14 have an inward clamping and pressing effect on the original tool 4 or the replacement tool 9, so as to facilitate subsequent disassembly and installation operations.

[0035] Working principle: When the present utility model is in use, first, a set of electromagnetic sliders 11 and electromagnetic guide rails 10 directly below the original tool 4 are started, so that the electromagnetic sliders 11 drive the corresponding movable blocks 7 to move to the leftmost side. Then, the corresponding electromagnet 1302 is started to be energized, so that the metal slide plate 1303 approaches and fits against the electromagnet 1302, thereby enabling the L-shaped pressing plate 1304 to push the two arc-shaped clamping plates 14 closer to each other, so that the arc-shaped clamping plates 14 clamp and fix the original tool 4. Then, the electromagnetic sliders 11 are started to slide to the right, so that the arc-shaped clamping plates 14 grab the original tool 4 and disassemble it from the tool holder 3;

[0036] Secondly, after the disassembly is completed, the motor 8 is started to rotate by 90°, so that the replacement tool 9 rotates to the installation position. The corresponding electromagnetic slider 11 is started to move to the left, so that the arc-shaped clamping plates 14 correspondingly insert the replacement tool 9 into the interior of the tool holder 3, that is, the replacement of the original tool 4 is realized. The corresponding electromagnet 1302 is started to be powered off, and then the clamping effect of the arc-shaped clamping plates 14 on the replacement tool 9 is released, and the electromagnetic slider 11 slides to the rightmost end to facilitate the next disassembly and replacement of the replacement tool 9;

[0037] Finally, by the action of the four groups of arc-shaped clamping plates 14, the three replacement tools 9 are respectively pre-clamped, and the original tool 4 to be replaced is disassembled and stored by using the vacant group of arc-shaped clamping plates 14, so as to realize the replacement of different tools for different machining operations.

For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
