DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A special-shaped workpiece grinding auxiliary device comprises an operating table 1, a second supporting frame 8, a fan 9 and a motor 10. A first supporting plate 2 is fixedly installed on the top of the operating table 1, and a supporting base 3 is fixedly installed on the top of the first supporting plate 2. Three sets of slide grooves are opened on the surface of the supporting base 3, and a threaded sleeve 17 is inserted inside the slide groove. A threaded groove is opened on the surface of the threaded sleeve 17, and a threaded rod 16 is inserted inside the threaded groove. A second supporting plate 15 is fixedly connected to the top of the threaded sleeve 17. First supporting frames 4 are symmetrically installed on both sides of the first supporting plate 2, and a protective cover 5 is fixedly connected to the top of the first supporting frame 4. A fixing plate 6 is fixedly installed on the front of the protective cover 5. A circular groove is opened on the back of the protective cover 5, and a fan 9 is fixedly installed inside the circular groove. The output end of the motor 10 is connected to the fan 9, and the motor 10 is fixedly installed through the second supporting frame 8.

[0024] Further, see Figure 2 It can be seen that a rectangular groove is opened on the surface of the fixed plate 6, and a protective rubber plate 7 is hingedly installed on the inner top of the rectangular groove. The protective rubber plate 7 has the ability to deform and expands inward under the action of the suction force of the fan 9, thereby facilitating dust to enter the interior of the protective cover 5.

[0025] Further, see Figure 4It can be known that a feed opening is provided at the bottom end of the protective cover 5, a support frame 12 is fixedly installed at the bottom end of the protective cover 5, and a collection bin 11 is installed on the surface of the support frame 12, and the collection bin 11 is located directly below the feed opening, thereby facilitating dust collection.

[0026] Further, see Figure 3 and Figure 4 It can be known that the bottom end of the first support frame 4 is fixedly connected with a fixed block 13, and a cylindrical slide groove is opened at the bottom end of the fixed block 13, a spring 20 is inserted inside the cylindrical slide groove, and the bottom end of the spring 20 is fixedly connected with a limit pin 14. During use, the contraction force of the spring 20 facilitates the storage of the limit pin 14 inside the cylindrical groove.

[0027] Further, see Figure 4 It can be known that sliding grooves are symmetrically opened at both ends of the first support plate 2, and the fixed block 13 is inserted inside the sliding groove. The fixed block 13 and the first support plate 2 are slidingly connected, and a limiting groove is opened at the inner bottom of the sliding groove. Under the elastic force of the spring 20 itself, the limiting pin 14 is pushed to be inserted inside the limiting groove. During use, it can play a limiting role on the first support frame 4.

[0028] Further, see Figure 4 It can be known that a connecting shaft 19 is fixedly connected at the center position of the fan 9, and a fixing ring 22 is fixedly sleeved on the surface of the connecting shaft 19, and a cleaning rod 21 is symmetrically fixedly connected to the upper and lower ends of the fixing ring 22. During use, the cleaning rod 21 can be rotated to clean the surface of the filter cover 18, thereby allowing the filter cover 18 to be used normally.

[0029] Further, see Figure 3 and Figure 4 It can be known that a filter cover 18 is inserted inside the protective cover 5, and the filter cover 18 is sleeved on the surface of the fan 9. During use, dust impurities in the air can be filtered through the filter cover 18 to avoid affecting the normal use of the fan 9.

[0030] Working principle: When the utility model is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5As shown, when the workpiece needs to be polished, the threaded rod 16 is rotated, and the threaded rod 16 rotates to drive the threaded sleeve 17 to move, and the threaded sleeve 17 moves to drive the second support plate 15 to move and adjust, so as to adapt to workpieces of different sizes. Then, the protective cover 5 is pulled forward so that the protective cover 5 is located at the upper rear of the support base 3, and the first support frame 4 is limited by the limit pin 14, and the motor 10 is powered on, and the motor 10 drives the fan 9 to blow out the air, and the protective rubber plate 7 is unfolded inwardly, and the external air enters through the protective rubber plate 7 and fills the protective cover 5. This structure sucks dust into the interior of the protective cover 5, and the sucked air passes through the filter cover 18, and the dirt is trapped at the same time. Fresh air passes through the fan 9 and is discharged;

[0031] After completing the preparation work, the staff places the workpiece on the surface of the second support plate 15, and grinds the surface of the workpiece with a handheld grinding gun. The dust generated during grinding is collected by the protective cover 5. At the same time, when the fan 9 is working, it can drive the connecting shaft 19 to rotate. The rotation of the connecting shaft 19 drives the cleaning rod 21 to rotate to clean the surface of the filter cover 18. After completing the work, pull the collection bin 11 outward for cleaning, and the operation is completed. The above is the entire working principle of the utility model.

[0032] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.
