[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Reference Figure 1-2 As shown, an embodiment of the utility model is: an easy-to-clean and anti-clogging vacuum suction cup, comprising a porous suction cup 1, a plurality of support blocks 2 are arranged on the porous suction cup 1, a circular hole 3 is downwardly arranged on the upper surface of the support block 2, a pneumatic valve 4 is arranged on the front side of the porous suction cup 1, the pneumatic valve 4 and the plurality of circular holes 3 are interconnected in the porous suction cup 1, the pneumatic valve 4 is used to suck air to form a negative pressure at the contact position between the workpiece and the circular hole 3 so as to fix the workpiece, a plurality of drainage channels 5 are arranged on the upper surface of the porous suction cup 1, and the drainage channels 5 are arranged horizontally On one side or both sides of the support block 2, the drainage channel 5 is inclined along the center toward both ends. The drainage channel 5 is inclined toward both sides so that the cleaning fluid or cutting fluid can quickly flow out of the porous suction cup 1, preventing the solution from remaining on the workpiece surface or on the suction cup for a long time and affecting the processing quality. A cleaning hole 6 is penetrated through the side of the porous suction cup 1, and the multiple cleaning holes 6 are respectively connected to the transverse circular holes 3, so that impurities and the like remaining on the surface of the workpiece can fall into the cleaning hole 6 through the circular hole 3, which is convenient for cleaning impurities. A cleaning device 7 is arranged above the porous suction cup 1.

[0017] Furthermore, the cleaning device 7 includes a cleaning rack 71, which is provided with a rectangular hole 72. An I-shaped slide groove 73 is provided on the lower surface of the cleaning rack 71. The multiple slide grooves 73 correspond one-to-one to the positions of the multiple drainage channels 5. A movable plate 74 is slidably arranged between two adjacent slide grooves 73. The movable plate 74 can be removed. When a movable plate 74 is removed, the dust or impurities in the circular hole 3 can be cleaned by reverse inflation of the pneumatic valve 4. A plurality of cleaning columns 75 are arranged in an array below the movable plate 74. The positions of the plurality of cleaning columns 75 correspond one-to-one to the positions of the plurality of circular holes 3. When the cleaning columns 75 move downward, the impurities remaining in the circular hole 3 can be pushed into the cleaning hole 6, thereby preventing the circular hole 3 from being blocked.

[0018] Furthermore, the diameter of the cleaning column 75 is adapted to the diameter of the circular hole 3. When the movable plate 74 contacts the upper surface of the support block 2, the cleaning column 75 is tangent to the side of the circular hole 3, preventing the cleaning column 75 from being too long and moving into the cleaning hole 6, thereby hindering the movement of the cleaning rod 8 in the cleaning hole 6 and causing the cleaning rod 8 to be unable to perform cleaning.

[0019] Furthermore, the distance between two adjacent slide grooves 73 is adapted to the width of the support block 2, so as to prevent the distance between the two adjacent slide grooves 73 from being too small so that the movable plate 74 cannot contact the support block 2, and the cleaning column 75 cannot move far enough to clean the impurities at the bottom of the circular hole 3. The height of the slide groove 73 is smaller than the height of the support block 2, so as to prevent the slide groove 73 from contacting the cleaning channel when the cleaning column 75 has not cleaned the bottom of the circular hole 3, so as to prevent the cleaning column 75 from being unable to move further downward.

[0020] Furthermore, a cleaning rod 8 is arranged in the cleaning hole 6, the diameter of the cleaning rod 8 is adapted to the diameter of the cleaning hole 6, the length of the cleaning rod 8 is greater than the length of the cleaning hole 6, and threaded plugs 9 are threadedly connected to both ends of the cleaning hole 6. The threaded plugs 9 seal the cleaning hole 6 so that there will be no air leakage when the porous suction cup 1 fixes the workpiece. The cleaning rod 8 moves in the cleaning hole 6 to clean out the impurities in the cleaning hole 6, thereby cleaning the impurities in the porous suction cup 1 without clogging and affecting the processing of the workpiece.

[0021] Working principle: When using the porous suction cup 1, the staff first uses the threaded plug 9 to seal the two ends of the cleaning hole 6, places the workpiece to be processed on the porous suction cup 1, starts the pneumatic valve 4 to adsorb the workpiece on the surface of the porous suction cup 1 and starts processing. The cutting fluid and cleaning fluid during processing flow out from the drainage channel 5. After completing the processing, the movable plate 74 is installed in the slide groove 73, and then the cleaning frame is moved downward to make multiple cleaning columns 75 overlap with the corresponding circular holes 3 one by one to push the impurities and dust in the circular holes 3 into the cleaning hole 6, remove the threaded plug 9 and insert the cleaning rod 8 into the cleaning hole 6 to remove the impurities in the cleaning hole 6 from the porous suction cup 1.

[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
