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

[0027] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, upper end, lower end, top, bottom...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] See also Figure 1-5 As shown, a spindle dust cover mechanism for a CNC machine tool includes a dust box 1 connected to the machine tool spindle 5, and two groups of dust pipe interfaces 101 are opened on the upper end of the dust box 1. The two groups of dust pipe interfaces 101 are arranged side by side. Of course, the above-mentioned dust pipe interfaces 101 are only one embodiment and are not used to limit the scope of this application. In actual settings, the number of groups of the dust pipe interfaces 101 can be other, but not less than 1 group, and the distribution method can also be other methods as long as the requirements can be met; when connected, the dust pipe interfaces 101 are connected to the dust collection equipment through corresponding dust pipes.

[0029] Continue to see Figure 1-3 As shown, a spindle dust hood 2 is provided at the bottom of the dust box 1 and is sleeved on the outside of the tool 6. The spindle dust hood 2 is detachably provided on the dust box 1 through a pneumatic quick-change device 3, and the spindle dust hood 2 is connected to the dust box 1, so that during the dust collection operation, the dust is sucked into the dust box 1 through the dust hood 2 and then transported to the dust collection device through the dust pipe interface 101.

[0030] In this embodiment, the pneumatic quick-change device 3 consists of two parts, a male head and a female head. During installation, the male head is fixed on the spindle dust cover 2, and the female head is fixed on the dust box 1.

[0031] In addition, see Figure 6-7As shown, in the present embodiment, the bottom opening of the spindle dust hood 2 is a dust suction port 201, and the dust suction port 201 is inclined at 30°. It has been verified in practice that this angle has a better dust suction effect than a straight angle. A pair of air inlets 202 are provided on the side of the dust suction port 201, and in the present embodiment, the pair of air inlets 202 are symmetrically arranged, and the air inlets 202 are arranged to allow external air to enter the spindle dust hood 2, thereby taking away the waste dust sucked in by the dust suction port 201, thereby realizing the spindle dust suction operation.

[0032] In addition, see Figure 6-7 As shown, in this embodiment, a pair of mutually symmetrical bayonet holes 203 are provided on the side wall of the spindle dust cover 2.

[0033] See also Figure 1-2 As shown, an air pressure sensor 7 is provided on the side wall of the dust collection box 1. The main function of the air pressure sensor 7 is to sense the pressure of the pneumatic quick change device 3 when the spindle dust collection cover 2 is replaced. When the pressure does not reach the loosening standard of the pneumatic quick change device 3, the male and female heads in the pneumatic quick change device 3 will not separate, that is, the spindle dust collection cover 2 will not detach from the dust collection box 1, thereby effectively avoiding damage to the equipment or the mechanism.

[0034] See also Figure 1-2 As shown, a proximity switch 8 is also provided at the bottom of the dust collection box 1. The main function of the proximity switch 8 is to determine whether the spindle dust collection hood 2 is properly connected to the dust collection box 1, thereby effectively avoiding the poor dust collection effect caused by the improper installation of the spindle dust collection hood 2 and the falling off of the spindle dust collection hood 2 during operation, thereby indirectly protecting the personal safety of the operator.

[0035] See also Figure 1-3 As shown, the mechanism also includes a clamping claw module 4, and in this embodiment, see Figure 8 As shown, the clamping claw module 4 includes a clamping claw finger cylinder 401 and a clamping claw 402, and the clamping claw 402 is fixed on the clamping claw finger cylinder 401; when setting, refer to Fig. 9 As shown, the clamping modules 4 are provided with five groups. Of course, it is not limited to five groups, and other numbers of groups can also be provided. The above is only one implementation mode. When providing, it is sufficient as long as the requirements can be met. The five groups of the clamping modules 4 are all provided on the machine tool equipment through the clamping finger cylinders 401 to which they belong, and the clamping claws 402 controlled by each group of the clamping finger cylinders 401 clamp a spindle dust hood 2 of corresponding specifications, thereby forming a dust hood library. At this time, the clamping claws 402 are all clamped at the bayonet 203.

[0036] The working principle of the utility model is as follows:

[0037] Before operation, install the dust box 1 on the spindle 5 of the machine tool, and connect the dust pipe interface 101 to the dust collection equipment through the corresponding dust pipe, then install the jaw module 4 on the machine tool, and put the spindle dust hood 2 of corresponding specifications in the jaw module 4; finally, connect the air pressure sensor 7 and the proximity switch 8 to the machine tool control system, and enter the specifications of the corresponding spindle dust hood 2 in the jaw module 4 into the control system.

[0038] During operation, after the tool 6 is replaced on the spindle 5, according to the length of the tool 6, the spindle 5 drives the tool 6 to move above the spindle dust cover 2 with the corresponding specification of the length of the tool 6. At this time, the female head of the pneumatic quick-change device 3 arranged at the bottom of the dust box 1 is partially opened, and the pressure of the pneumatic quick-change device 3 is sensed by the air pressure sensor 7 arranged on the side wall of the dust box 1, and the pressure is fed back to the control system to judge the state of the pneumatic quick-change device 3. After confirming that there is no problem, the spindle 5 drives the tool 6 to move downward, so that the dust box 1 installed on the spindle 5 is connected with the spindle dust cover 2 through the pneumatic quick-change device 3. At this time, the tool 6 is removed from the dust cover. 2, and the lower end passes through the dust suction port 201; at the same time, the proximity switch 8 arranged at the bottom of the dust suction box 1 determines whether the dust suction box 1 and the spindle dust suction cover 2 are connected in place, and feeds back the signal to the control system. When it is confirmed to be in place, the clamp finger cylinder 401 controls the clamping claw 402 to open, and the spindle 5 takes away the spindle dust suction cover 2 to operate; wherein, during the operation, the dust suction equipment is started, and the external air enters the spindle dust suction cover 2 through the air inlet 202, and the waste dust sucked by the dust suction port 201 is brought into the dust suction box 1 through the spindle dust suction cover 2, and then discharged from the dust suction pipe interface 101, and collected into the dust suction equipment through the dust suction pipe.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
