Description

Technical Field

[0001] This utility model relates to the field of CNC machining center technology, and in particular to a CNC machining tool changing device. Background Technology

[0002] In CNC machining, tool changes are required frequently to meet different machining needs. When changing tools, a robotic arm is usually used to grab and exchange the tools to achieve the purpose of tool changing.

[0003] During CNC machining, a large number of tools are used. Existing tool changers are cumbersome to operate, resulting in low efficiency. Furthermore, the removed tools are often covered with cutting chips, coolant residue, or material buildup. Existing tool changers do not facilitate cleaning of the removed tools, leading to residual chips and buildup that accelerate tool wear, affect cutting edge sharpness, and shorten tool life. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a CNC machining tool changing device that can quickly switch tools, thereby improving the efficiency of tool changing and cleaning the replaced tools to extend their service life.

[0005] The technical solution is: a CNC machining tool changer, comprising:

[0006] Mounting plate;

[0007] Two guide rails fixed to the mounting plate;

[0008] Electric sliders are respectively slidably connected to two guide rails;

[0009] A tool magazine with a notch is fixed to an electric slider;

[0010] A switching component located on the tool magazine;

[0011] Eight sets of clamping components are mounted on the rotating frame;

[0012] Cleaning components located on the tool magazine.

[0013] Furthermore, the switching component includes: a servo motor fixed to the tool magazine; and a rotating frame fixed to the output shaft of the servo motor.

[0014] Furthermore, the clamping assembly includes: each clamping assembly consists of two jaws and a torsion spring, the two jaws are symmetrically arranged, and both jaws are rotatably connected to the rotating frame; both jaws are connected to the rotating frame by a torsion spring.

[0015] Furthermore, a cutting tool is held on one of the clamping components.

[0016] Furthermore, the cleaning assembly includes: a rotating column fixed to a rotating frame; a sliding actuating frame slidably connected to the rotating column; a first compression spring connecting the actuating frame and the rotating column; a squeezing block fixed to the inner wall of the tool magazine; an arc-shaped rod fixed to the inner wall of the tool magazine; a double-layer brush slidably connected to the arc-shaped rod; and a second compression spring connecting the double-layer brush and the arc-shaped rod.

[0017] The beneficial effects of this utility model are as follows: 1. When the tool is inserted between the grippers, the grippers will clamp the tool to be replaced under the action of the torsion spring. Then, the operator controls the tool shaft to release the tool. Subsequently, the operator controls the output shaft of the servo motor to rotate. The rotation of the output shaft of the servo motor will drive the tool to be replaced to rotate through the rotating frame. The angle of rotation of the servo motor is controlled according to the tool number to be replaced to correspond to the tool shaft. The tool shaft and the tool are connected to complete the tool replacement, thereby making the tool replacement faster and more accurate, thus improving the tool replacement efficiency.

[0018] 2. When the rotating frame switches tools, the upper and lower ends of the tool will contact the double-layer brush. At the same time, as the frame rotates, it will repeatedly push the double-layer brush to move. Under the action of the first compression spring and the second compression spring, the double-layer brush will move back and forth, thereby brushing the two ends of the replaced tool to remove the metal shavings adhering to the tool and thus extend the service life of the tool.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Example 1: A CNC machining tool changer, such as Figures 1-6 As shown, it includes:

[0028] Mounting plate 0;

[0029] Two guide rails 1 are fixed to the mounting plate 0;

[0030] Electric sliders 2 are respectively slidably connected to two guide rails 1;

[0031] The tool magazine 3 with a notch is fixedly connected to the electric slider 2;

[0032] A switching component located on tool magazine 3;

[0033] Eight sets of clamping components 6 are mounted on the rotating frame 5;

[0034] Cleaning components are located on the tool magazine 3.

[0035] The switching component includes: a servo motor 4 fixed to the tool magazine 3; and a rotating frame 5 fixed to the output shaft of the servo motor 4.

[0036] The clamping assembly 6 includes: each clamping assembly 6 consists of two jaws 61 and a torsion spring 62, the two jaws 61 are symmetrically arranged, and both jaws 61 are rotatably connected to the rotating frame 5; both jaws 61 are connected to the rotating frame 5 by a torsion spring 62.

[0037] One of the clamping components 6 holds the cutting tool 7.

[0038] The cleaning assembly includes: a rotating column 8 fixed to the rotating frame 5; a sliding actuating frame 9 slidably connected to the rotating column 8; a first compression spring 10 connecting the actuating frame 9 and the rotating column 8; a squeezing block 11 fixed to the inner wall of the tool magazine 3; an arc-shaped rod 12 fixed to the inner wall of the tool magazine 3; a double-layer brush 13 slidably connected to the arc-shaped rod 12; and a second compression spring 14 connecting the double-layer brush 13 and the arc-shaped rod 12.

[0039] Initially, the operator installs the device on the CNC machining center using mounting plate 0. During tool changes, the operator first clamps the pre-prepared tool 7 using jaws 61, leaving a gap. When a tool change is needed, the operator controls the electric slider 2 to move closer to the CNC tool spindle, simultaneously moving the tool magazine 3 and aligning the gap with the CNC tool spindle. As the tool magazine 3 moves, it also moves the jaws 61 via the rotating frame 5. As the jaws 61 move, they contact the tool 7 on the CNC tool spindle. As the jaws 61 continue to move, the tool 7 on the CNC tool spindle will press against the two... The gripper 61 rotates in opposite directions. When the tool 7 is engaged between the grippers 61, the torsion spring 62 clamps the tool 7 to be replaced. The operator then controls the tool shaft to release the tool 7. Subsequently, the operator controls the output shaft of the servo motor 4 to rotate. This rotation of the servo motor 4 drives the tool 7 to rotate via the rotating frame 5. The rotation angle of the servo motor 4 is controlled according to the tool number to be replaced, aligning with the tool shaft. The tool shaft connects to the tool 7, completing the tool change. This makes tool changing faster and more precise, thus improving tool changing efficiency. The rotating frame 5... As the cutting tool 7 rotates, the rotating column 8 also rotates. The rotation of the rotating column 8, in turn, causes the actuating frame 9 to rotate and pushes the double-layer brush 13 to move. The second compression spring 14 is compressed. As the actuating frame 9 continues to rotate, one side of it contacts the pressing block 11. The pressing block 11 presses against the actuating frame 9, causing it to move downwards. The first compression spring 10 is compressed. The downward movement of the actuating frame 9 disengages from the double-layer brush 13. The second compression spring 14 resets, causing the double-layer brush 13 to reset. Simultaneously, the actuating block disengages from the pressing block 11, and the first compression spring 10 resets, causing the actuating frame 9 to reset. This process repeats. Therefore, while the rotating frame 5 is switching the tool 7, the upper and lower ends of the tool 7 will contact the double-layer brush 13. At the same time, as the rotating frame 9 rotates, it will repeatedly push the double-layer brush 13 to move. Under the action of the first compression spring 10 and the second compression spring 14, the double-layer brush 13 will move back and forth, thereby brushing the two ends of the replaced tool 7 to remove the metal shavings adhering to the tool 7, thus extending the service life of the tool 7. After the tool change is completed, the operator controls the electric slider 2 to move in the opposite direction to move the tool magazine 3 away from the processing area. At the same time, the tool magazine 3 can protect the tool 7. Repeat this operation to perform the next tool change.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
