Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and more specifically, to a CNC quick tool change mechanism for automotive parts processing. Background Technology

[0002] CNC machine tools are needed for the processing of automotive parts. Different types of CNC machine tools are required depending on the processing steps. When a CNC machine tool is working, the cutting head needs to be changed to facilitate its operation.

[0003] For example, CN216542110U discloses a CNC quick tool changer for machining automotive parts. The key technical points of this device are: it includes a tool changer box, a rotary drive component, a transmission rod, and an adapter sleeve. The top of the tool changer box is provided with an adapter sleeve. A drive mechanism is provided outside the tool changer box on one side of the adapter sleeve. A linkage rod is installed at the bottom of the adapter sleeve, and the bottom end of the linkage rod extends into the interior of the tool changer box. A drive rod is installed at the bottom end of the linkage rod, and a driven gear is installed at the bottom end of the drive rod. A rotary drive mechanism is installed inside the tool changer box on one side of the drive rod. The rotary drive component has a transmission rod mounted at its bottom end, and a drive gear is mounted at its bottom end. It primarily works by opening the rotary drive component, which drives the transmission rod to rotate, which in turn drives the drive gear to rotate. The drive gear then moves the timing belt, which in turn drives the drive rod to rotate, which in turn drives the linkage rod to rotate. Finally, the adapter sleeve drives the annular tool disc to rotate, thus moving the CNC tool. This achieves stable rotary drive movement of the tool in the CNC quick tool changer, facilitating tool selection and movement.

[0004] The aforementioned CNC quick tool change mechanism for automotive parts processing also has certain shortcomings: heat is generated inside the quick tool change mechanism, and once the heat accumulates, the quick tool change mechanism will not be able to operate normally, thereby reducing the working efficiency of the device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a CNC quick tool change mechanism for machining automotive parts, so as to solve the problems existing in the prior art.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a CNC quick tool change mechanism for automotive parts processing, including a quick tool change main protective shell, a first bearing is embedded in the middle of the lower surface of the quick tool change main protective shell, a drive mechanism is detachably installed at the bottom of the interior of the quick tool change main protective shell, a drive shaft is connected to the bottom of the drive mechanism through the first bearing, a mounting plate is fixedly connected to the bottom of the drive shaft, a plurality of tool heads are fixedly connected to the bottom of the mounting plate in a circular array, a cooling component is embedded in the top of the side wall of the quick tool change main protective shell, two wiring components are fixedly connected side by side at equal intervals on the side wall of the quick tool change main protective shell, and a plurality of ventilation holes are opened in a rectangular array on the other side wall of the quick tool change main protective shell.

[0007] The cooling assembly includes an anti-collision housing, a support frame, and a second bearing. The support frame is fixedly connected to the side wall of the anti-collision housing, and the second bearing is embedded in the center of the side wall of the support frame.

[0008] The support frame has a motor detachably installed in the middle of its side wall, and one end of the motor is electrically connected to a power supply line.

[0009] The other end of the motor is connected to a rotating shaft via a second bearing, and one end of the rotating shaft is fixedly connected to multiple cooling blades in a circular array.

[0010] The wiring assembly includes a stabilizing base and a first limiting frame. The first limiting frame is fixedly connected to the middle of the upper surface of the stabilizing base, and the lower surface of the stabilizing base is connected to the side wall of the quick-change tool body protective shell.

[0011] The first limiting frame has two third bearings symmetrically embedded on its surface along the center. The third bearings have a first movable wheel fixedly sleeved inside them, and the top of the first movable wheel is adapted to the surface of the motor.

[0012] The upper surface of the first limiting frame has multiple grooves arranged in a rectangular array. The bottom of the groove is fixedly connected to a limiting telescopic rod. A return spring is fixedly sleeved on the surface of the limiting telescopic rod. The top of the return spring is fixedly connected to a second limiting frame.

[0013] The second limiting frame has two fourth bearings symmetrically embedded on its surface. The fourth bearings have a second movable wheel fixedly fitted inside them, and the bottom end of the second movable wheel is adapted to the surface of the power connection wire.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] 1. In the above scheme, the quick tool change mechanism is equipped with a wiring assembly. Before the cooling assembly works, the second limiting frame inside the wiring assembly moves the reset spring and the limiting telescopic rod upward. After moving a certain distance, one end of the power connection cable passes through the center of the first movable wheel and the second movable wheel. Then, the second limiting frame is slowly released. Immediately afterwards, the reset spring will drive the second limiting frame to return to its original position, so that the first movable wheel and the second movable wheel restrict the position of the power connection cable that has passed through, so as to avoid the power connection cable from getting tangled with other components, thereby reducing the difficulty of later maintenance.

[0016] 2. In the above solution, the quick tool change mechanism is equipped with a cooling component. When a certain amount of heat is generated inside the quick tool change main body protective shell, the power connection wire inside the cooling component is connected to an external power source through a plug, causing the motor to work. Then, the motor drives the rotating shaft and cooling blades to rotate rapidly through the second bearing. Because the rapidly rotating cooling blades can generate airflow, the heat generated inside the quick tool change main body protective shell can be discharged through the ventilation holes, thus cooling the inside of the quick tool change main body protective shell, which facilitates the operation of the quick tool change mechanism and saves time.

A first bearing 2 is embedded in the middle of the lower surface of the quick tool change main protective shell 1. A drive mechanism 3 is detachably installed at the bottom inside the quick tool change main protective shell 1. A drive shaft 4 is connected to the bottom of the drive mechanism 3 through the first bearing 2. A mounting plate 5 is fixedly connected to the bottom of the drive shaft 4. Multiple tool heads 6 are fixedly connected to the bottom of the mounting plate 5 in a circular array.

Two wiring components 8 are fixedly connected side by side at equal intervals on the side wall of the quick tool change main protective shell 1. Multiple ventilation holes are opened in a rectangular array on the other side wall of the quick tool change main protective shell 1.

[0026] The cooling assembly 7 includes an anti-collision housing 71, a support frame 72, and a second bearing 73. The support frame 72 is fixedly connected to the side wall of the anti-collision housing 71. The second bearing 73 is embedded in the center of the side wall of the support frame 72. A motor 74 is detachably installed in the middle of the side wall of the support frame 72. One end of the motor 74 is electrically connected to a power connection line 75, and the other end of the motor 74 is connected to a rotating shaft 76 through the second bearing 73. One end of the rotating shaft 76 is fixedly connected to multiple cooling blades 77 in a circular array. The wiring assembly 8 includes a stabilizing base 81 and a first limiting frame 82. The first limiting frame 82 is fixedly connected to the middle of the upper surface of the stabilizing base 81, and the lower surface of the stabilizing base 81 is connected to the side wall of the quick-change main body protective housing 1. Next, two third bearings 83 are symmetrically embedded in the surface of the first limiting frame 82. A first movable wheel 84 is fixedly sleeved inside the third bearing 83. The top of the first movable wheel 84 is adapted to the surface of the motor 74. Multiple grooves are formed in a rectangular array on the upper surface of the first limiting frame 82. A limiting telescopic rod 85 is fixedly connected to the bottom of the groove. A return spring 86 is fixedly sleeved on the surface of the limiting telescopic rod 85. A second limiting frame 87 is fixedly connected to the top of the return spring 86. Two fourth bearings 88 are symmetrically embedded in the surface of the second limiting frame 87. A second movable wheel 89 is fixedly sleeved inside the fourth bearing 88. The bottom of the second movable wheel 89 is adapted to the surface of the power connection line 75.

[0027] Benefits: The ventilation holes help improve the cooling rate of the device, thereby enhancing its practicality.

[0028] The working process of this utility model is as follows:

[0029] To reduce the difficulty of later maintenance, the quick tool change mechanism is equipped with a wiring assembly 8. Before the cooling assembly 7 is activated, the second limiting frame 87 inside the wiring assembly 8 moves the return spring 86 and the limiting telescopic rod 85 upward. After moving a certain distance, one end of the power connection cable 75 passes through the center of the first movable wheel 84 and the second movable wheel 89. Then, the second limiting frame 87 is slowly released, and the return spring 86 moves the second limiting frame 87 back to its original position. This restricts the position of the power connection cable 75 by the first movable wheel 84 and the second movable wheel 89, preventing the power connection cable 75 from getting tangled with other components, thereby reducing the difficulty of later maintenance.

[0030] In the above scheme, the quick tool change mechanism is equipped with a cooling component 7 to improve the working efficiency of the device. When a certain amount of heat is generated inside the quick tool change main protective shell 1, the power connection wire 75 inside the cooling component 7 is connected to an external power source through a plug, causing the motor 74 to work. Then, the motor 74 drives the rotating shaft 76 and the cooling blades 77 to rotate rapidly through the second bearing 73. Because the rapidly rotating cooling blades 77 can generate airflow, the heat generated inside the quick tool change main protective shell 1 can be discharged through the ventilation holes, cooling the inside of the quick tool change main protective shell 1, thereby facilitating the operation of the quick tool change mechanism and saving time.
