[0002] At present, most of the self-clinching nuts need to be polished on the outside during production.

Restricted by the protrusion 22 and the arc groove 23, the inclined plate 21 will swing back and forth along its own shaft to shake off the debris accumulated at the inclined end. At the same time, each auxiliary device is continuously started, and each air pump continuously generates airflow to blow the debris on the work table to the discharge port 15, completing the self-collection of the debris and greatly reducing manpower loss.

[0019] Embodiment 2, on the basis of embodiment 1, a mounting groove 4 is provided inside the main mounting plate 1, the rotating shaft of the grinding tool 2 is rotatably connected to the inside of the mounting groove 4, a linkage mechanism is provided inside the mounting groove 4, the linkage mechanism includes a connecting belt 5, a horizontal rod 6 is rotatably connected to the inner wall of one side of the mounting groove 4, one end of the horizontal rod 6 passes through the outer wall of the main mounting plate 1 and is rotatably connected to the auxiliary mounting plate 3, an absorption component is provided above the horizontal rod 6, the absorption component includes a horizontal rod 2 8 and a suction fan blade 11, and the connecting belt 5 is transmission-connected to the horizontal rod A horizontal rod 28 is rotatably connected between the main mounting plate 1 and the auxiliary mounting plate 3, and a column gear 7 is fixedly connected to the outer wall of the horizontal rod 16. A column gear 29 that meshes with the column gear 17 is fixedly connected to the outer wall of the horizontal rod 28. A meshing assembly 10 is arranged on the outer wall of the horizontal rod 28. The meshing assembly 10 includes a bevel gear 1 and a bevel gear 2. The bevel gear 1 is fixedly connected to the outer wall of the horizontal rod 28. The bevel gear 1 meshes with the bevel gear 2.

The bottom ends of the two guide blocks 17 are fixedly connected with triangular blocks 16, and an inclined plate 21 is rotatably connected between the two triangular blocks 16. The outer wall of the horizontal rod 16 is transmission-connected with a connecting belt 2 18, one end of the connecting belt 2 18 is located inside the mounting groove 4, and one end of the connecting belt 2 18 passes through the main mounting plate 1 and the machine tool and is transmission-connected with a short shaft 19.

[0020] It should be noted here that: Figure 3 , 4 5. The cross section of the collecting frame 12 is much larger than that of the grinding tool 2. The splash range of metal debris and other impurities generated during the grinding of the rivet nut by the grinding tool 2 is within the range of the collecting frame 12. That is, the collecting frame 12 can block the splashing metal debris and other impurities to avoid environmental pollution and threats to the safety of operators. The grinding tool 2 is attached to the manual. Figure 4In the state, it rotates in the clockwise direction, then most of the debris after the interaction with the rivet nut will fly to between the main mounting plate 1 and the auxiliary mounting plate 3, and a small amount of debris will stay on the work table and the machine tool after collision, through the partition mesh 2 14 and the partition mesh 1 13, the partition mesh 2 14 performs the first blocking of the flying metal debris and other impurities, and the partition mesh 1 13 performs the second blocking of the flying metal debris and other impurities, and more importantly, protects the suction fan blades 11 to prevent the flying metal debris and other impurities from affecting the adsorption effect of the suction fan blades 11, no matter the metal debris blocked by the partition mesh 1 13 or the partition mesh 2 14 will eventually fall into the discharge port 15 below due to its own gravity, pass through the discharge port 15 and fall on the inclined plate 21 or the two guide blocks 17, the two guide blocks 17 have a steeper inclined surface than the inclined plate 21, so that metal debris and other impurities are easier to fall, which is beneficial to the subsequent collection operation.

[0021] Embodiment 3, on the basis of embodiment 2, there are two short shafts 19 and a cross bar is fixedly connected between the two short shafts 19, the outer walls of the two short shafts 19 are rotatably connected with side plates, the top ends of the two side plates are fixedly connected to the bottom end of the machine tool, the outer wall of the cross bar is fixedly connected with multiple groups of equidistantly arranged bumping components, each group of bumping components includes four firing components 20 that are rotationally symmetrical and equidistantly arranged with the axis of the cross bar as the center, and the firing components 20 include a rubber rod and a rubber block and are connected by the two The two triangular blocks 16 are spliced ​​together, the rubber rod is fixedly connected to the outer wall of the cross bar, the rubber block is movably connected to the inclined plate 21, a part of the inclined plate 21 is located inside the compensation groove 25 but the two have no contact relationship, the outer walls on both sides of the inclined plate 21 are fixedly connected with protrusions 22, and the outer walls of the two triangular blocks 16 on one side close to the inclined plate 21 are provided with arc grooves 23, the protrusions 22 are slidably connected to the inside of the arc groove 23, and an elastic member 24 is fixedly connected between the protrusion 22 and one end of the inner wall of the arc groove 23.

[0022] Through the connection belt 1 5 and the connection belt 2 18, under their connection, the rotation of the grinding tool 2 will drive the horizontal rod 1 6, thereby further driving the short shaft 1 19, and the cross bar between the two short shafts 19 will also rotate accordingly, and the suction fan blades 11 can be rotated at the same time through the mutually meshing bevel gear 1 and the bevel gear 2. The setting of the stable frame provides a basis for the rotation of the suction fan blades 11, ensuring its stable rotation and thus ensuring the adsorption effect. The two guide blocks 17 play a role in guiding and draining, transferring impurities such as metal debris to the inclined plate 21, which is conducive to the gathering and collection of impurities such as metal debris. In the initial state, that is, before the operation of the grinding tool 2, since the two short shafts 19 rotate with the start-up of the grinding tool 2, the synchronous rotation of the cross bar will drive the various bump components to operate together. At this time, each rubber block will impact the outer wall of the inclined plate 21. Refer to the attached manual Figure 7By setting the protrusion 22 and the elastic member 24, since the inclined plate 21 is rotatably connected between the two triangular blocks 16, and the rotating shaft is located in the middle of the inclined plate 21, after being impacted by the rubber block, the inclined plate 21 rotates along the axis, and its lower end will drive the protrusion 22 to compress the elastic member 24. Since the two firing assemblies 20 are separated by a distance, there is also an interval time between the impacts of the two adjacent rubber blocks on the inclined plate 21. During this time, the inclined plate 21 loses the external force impact, and the force on the elastic member 24 gradually decreases, and its rebound pushes the protrusion 22 back to its original position. When another rubber block impacts the inclined plate 21, the elastic member 24 will be compressed again, and so on. When the grinding tool 2 is started, the inclined plate 21 will be in a state of high-frequency swinging around its shaft, so as to vibrate the metal debris and other impurities accumulated or retained on the inclined plate 21 to the inside of the collection box below, thereby greatly improving the collection efficiency of the metal debris and other impurities generated during the grinding of the rivet nuts. Because the protrusion 22 always slides inside the arc groove 23 and is fixedly connected to the inclined plate 21, the swing range of the inclined plate 21 can be limited to be within a normal range. When the inclined plate 21 is impacted by the rubber block, the inclined plate 21 deflects inside the compensation groove 25. The opening of the compensation groove 25 provides space for the normal deflection of the inclined plate 21.

[0023] Embodiment 4 is based on Embodiment 3, one end of short shaft 19 passes through the side plate, the outer walls of the two short shafts 19 are both transmission-connected with connecting belt 3 27, one end of connecting belt 3 27 passes through the machine tool and is transmission-connected with rotating shaft 2 28, the outer wall of rotating shaft 28 is rotatably connected with a stabilizing block, the stabilizing block is fixedly connected to the top of the machine tool, one end of rotating shaft 28 is fixedly connected with a blowing fan blade, two conveying pipes 29 are arranged on the top of the machine tool, the features of the components arranged at one end of the two conveying pipes 29 are the same, the blowing fan blade is located inside the conveying pipe 29, one end of the conveying pipe 29 is fixedly connected with a diverter box 30, one end of the diverter box 30 is fixedly connected with three equally spaced strengthening nozzles 31, the strengthening nozzle 31 is arranged obliquely downward, and a splash plate 26 is fixedly connected between the two triangular blocks 16.

[0024] The fixation of the side plate provides a basis for the stable rotation of the short shaft 19. It should be noted here that: three equally spaced through slots are provided inside the diverter box 30, and the interior of each through slot is connected to the interior of the delivery pipe 29, and the interior of each through slot is connected to the interior of each enhanced nozzle 31. Under the connection of the connecting belt 3 27, the rotating shaft 28 rotates to drive the fan blades to rotate, and the airflow generated passes through the delivery pipe 29 and the diverter box 30 successively, and is finally transported to the interior of each enhanced nozzle 31 in equal volumes under the action of the diverter box 30, as shown in the attached manual. Figure 8It can be seen that the gas flow path here is indicated by the arrow. Because the cross-sectional area of ​​the internal channel of the intensified nozzle 31 is suddenly reduced, according to the principle of fluid mechanics (the increase in flow rate means the increase in fluid kinetic energy, thereby enhancing the impact force of the fluid), the flow rate of the airflow will increase, and the debris retained on the machine tool will be swept away. They can only fall through the discharge port 15 in the end. The setting of the splash plate 26 greatly reduces the probability of debris splashing to the outside of the collection box, which is conducive to the collection operation.

[0025] Embodiment 5 On the basis of Example 3, the width of the compensation groove 25 is greater than the width of the inclined plate 21, the arc-shaped rack 32 is located between the inclined plate 21 and the compensation groove 25, the width of the tooth plate 34 is smaller than the inclined plate 21, the movement trajectories of the arc-shaped rack 32 and the tooth plate 34 do not interfere with each other, the outer walls on both sides of the tooth plate 34 are fixedly connected to the limiting blocks 35, and the inner walls on both sides of the compensation groove 25 are provided with limiting grooves, and the limiting blocks 35 are slidably connected to the inside of the limiting grooves.

[0026] It should be noted here that the air pump is an existing tool, and its specific working principle will not be elaborated in detail. When the inclined plate 21 is impacted by the firing assembly 20, the inclined plate 21 will swing back and forth along its own shaft through the provided protrusion 22 and the arc groove 23, and synchronously drive the arc rack 32 to swing back and forth. Under the meshing connection of the column gear three 33 and the cooperation of the limit block 35 and the limit groove, the tooth plate 34 can only move up or down at a fixed tilt angle. This process is fed back to the air pump, and the adjusting end of the air pump is sometimes away from the inside of the air pump and sometimes close to the inside of the air pump. Then, the jet pipe connected at one end thereof will spray gas and act on the work table, blowing the debris on the work table to the discharge port 15, completing the self-collection of the debris, and greatly reducing manpower loss.

[0027] In actual use, through the connection belt 1 5 and the connection belt 2 18, under their connection, the rotation of the grinding tool 2 will drive the horizontal rod 1 6, thereby further driving the short shaft 19, and the cross bar between the two short shafts 19 will also rotate accordingly, and the suction fan blades 11 can be rotated at the same time through the mutually meshing bevel gear 1 and bevel gear 2. The setting of the stable frame provides a basis for the rotation of the suction fan blades 11, ensuring its stable rotation and thus ensuring the adsorption effect. The two guide blocks 17 play a role in guiding and draining, transferring impurities such as metal debris to the inclined plate 21, which is conducive to the gathering and collection of impurities such as metal debris. The synchronous rotation of the cross bar will drive each bump component to operate together. At the same time, each rubber block will impact the outer wall of the inclined plate 21. Through the provided protrusions 22 and arc grooves 23, the inclined plate 21 will swing back and forth along its own shaft, and synchronously drive the arc rack 32 to swing back and forth. Under the meshing connection of the column gear three 33 and the cooperation of the limit block 35 and the limit groove, the tooth plate 34 can only move up or down at an inclined angle. This process is fed back to the air pump, and the adjusting end of the air pump is sometimes away from the inside of the air pump and sometimes close to the inside of the air pump. The jet pipe connected at one end will spray gas and act on the work table, blowing the debris on the work table to the discharge port 15, completing the self-collection of the debris, and greatly reducing manpower loss.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
