[0019] Compared with the prior art, the present invention provides a barbell fixing nut manufacturing device, which has the following beneficial effects:

[0020] 1. The barbell fixed nut manufacturing equipment, through a series of operations of the automatic profiling motion component, enables the sanding belt on the swing grinding component to evenly grind along the contour of the barbell nut. Under the action of the rack and gear in the automatic profiling motion component, the moving block and the swing grinding component thereon can also move synchronously in a mirror image. Through a series of operations of the automatic profiling motion component, the sanding belt on the swing grinding component can evenly grind along the contour of the barbell nut, which can make barbell nuts of different sizes and different contours can be evenly polished, thereby improving the use range of the equipment.

[0021] 2. The barbell fixed nut manufacturing equipment, through the automatic profiling motion component, enables the sanding belt on the swinging grinding component to evenly grind along the contour of the barbell nut, and also enables each barbell nut to obtain effective trajectory control when the corners are being ground, thus avoiding the problem of easily damaging the area outside the rounded corners during the traditional rounding process, thereby affecting the surface quality of the barbell nut.

[0022] 3. The barbell fixed nut manufacturing equipment drives the inclined slide bar fixing frame and the inclined slide bar on the cooling and cleaning assembly to move synchronously by swinging the first sliding plate on the grinding component, so that the cooling sponge on the sponge fixing plate can also move in accordance with the outer contour of the barbell nut. While the cooling sponge moves in accordance with the outer contour of the barbell nut, the cooling cleaning liquid is evenly applied to the outer contour of the barbell nut. This enables the iron filings and other impurities attached to the rounded surface of the barbell nut after one round of grinding to be cleaned away by the cooling sponge, thereby avoiding the problem that the iron filings and other impurities attached to the barbell nut affect the next round of grinding effect, thereby improving the efficiency of grinding the rounded corners of the barbell nut to a certain extent.

[0023] 4. In the barbell fixing nut manufacturing equipment, the cooling sponge on the cooling and cleaning component can move in accordance with the outer contour of the barbell nut, and the cooling cleaning liquid in the cooling sponge can cool the polished rounded surface of the barbell nut after the barbell nut is polished. This avoids damage to equipment such as the sanding belt due to excessive temperature during the polishing of the barbell nut, and also avoids annealing of the barbell nut due to excessive temperature, which affects the structural performance, and to a certain extent ensures the stability of the quality of the barbell nut.

[0024] 5. The barbell fixed nut manufacturing equipment can also drive the arc-shaped dust suction nozzle on the dust suction nozzle fixing plate in the uniform dust removal and cleaning component to swing synchronously when the arc-shaped slide plate on the swinging and grinding component swings back and forth synchronously with the center trajectory of the arc-shaped fixed slider, thereby sucking away and collecting the powder splashed out when the sand belt grinds the barbell nut. This can prevent the splashed powder from being brought into the air and affecting the health of the workers when grinding the barbell nut, thereby improving the safety of the barbell nut production to a certain extent, avoiding the problem of powder contaminating the working environment, and improving the cleanliness of the working space.

[0025] 6. The barbell fixed nut manufacturing equipment can swing back and forth synchronously with the center trajectory of the arc-shaped fixed slider through the equipment mounted on the arc-shaped slide plate. This reciprocating swing can make the sanding belt contact and grind the outer contour of the barbell nut while also grinding the upper and lower corners of the barbell nut. Finally, the polished fillet is smoothly tangent to the edge of the barbell nut on three sides, so that there is no obvious edge line on the edge of the barbell nut in visual effect, which greatly improves the appearance quality of the barbell nut.

[0026] 7. The barbell fixing nut manufacturing equipment has rounded corners polished by a sand belt and smoothly tangent to the edge of the barbell nut on three sides, which can also prevent the barbell nut from feeling obvious edges when it is gripped and twisted. It also allows users to fit the barbell nut more closely to the human skin, avoiding the situation where the edges hurt the hand, and greatly improving the gripping effect of the barbell nut.

[0059] Furthermore, by being able to move simultaneously along the contour of the barbell nut on the swinging polishing assembly, the first sliding plate 16 on the swinging polishing assembly will drive the inclined slide bar fixing frame 30 and the inclined slide bar 31 on the cooling and cleaning assembly to move synchronously, and the synchronously moving inclined slide bar 31 can drive the inclined slider 33 to move along the trajectory of the inclined slide groove rail 32, so that the cooling sponge 35 on the sponge fixing plate 34 can also move in accordance with the outer contour of the barbell nut, and the water outlet of the water storage dropper bottle 36 can continuously drip cooling cleaning liquid, and the cooling cleaning liquid wets the cooling sponge 35 through the connecting water pipe 37. While the cooling sponge 35 moves in accordance with the outer contour of the barbell nut, the cooling cleaning liquid is evenly applied to the outer contour of the barbell nut. This can enable the iron filings and other impurities attached to the fillet surface of the barbell nut after being polished for one circle to be cleaned away by the cooling sponge 35, thereby avoiding the problem that the iron filings and other impurities attached to the barbell nut affect the next circle of polishing effect, and to a certain extent improves the efficiency of the barbell nut fillet polishing.

[0060] Furthermore, the cooling sponge 35 on the cooling and cleaning assembly can move in accordance with the outer contour of the barbell nut, and the cooling cleaning liquid in the cooling sponge 35 can cool the polished rounded surface of the barbell nut after the barbell nut is polished. This avoids damage to equipment such as the sanding belt 12 due to excessive temperature during polishing of the barbell nut, and also avoids annealing of the barbell nut due to excessive temperature, which affects the structural performance, and to a certain extent ensures the stability of the quality of the barbell nut.

[0061] Furthermore, when the arc-shaped slide plate 4 on the swinging grinding component swings back and forth in synchronization with the center trajectory of the arc-shaped fixed slider 3, it can also drive the arc-shaped dust nozzle 39 on the dust nozzle fixing plate 38 in the uniform dust removal and cleaning component to swing synchronously, and the start of the dust suction component 43 can suck air into the arc-shaped dust nozzle 39 through the dust suction hose 41 and the connecting pipe 40, thereby sucking away and collecting the powder splashed out when the sanding belt 12 grinds the barbell nut. This can prevent the splashed powder from being brought into the air and affecting the health of the staff when grinding the barbell nut, thereby improving the safety of the barbell nut production to a certain extent, and also avoiding the problem of powder polluting the working environment, thereby improving the cleanliness of the working space.

[0062] Working principle: When in use, the barbell nut on the nut feeding assembly 46 is moved to the position between the profiling roller 24 and the abrasive belt 12 through the operation of the feeding robot arm 45, and the profiling tension spring 28 is arranged, which drives the roller fixing block 23 and the moving block 2 to approach each other through the meshing of the two racks 25 and the second gear 27, until the profiling roller 24 fits with the barbell nut. At this time, the abrasive belt 12 will also be deformed under the action of the tensioning spring 14, so as to fit the contour and corners of the barbell nut. At this time, by starting the first motor 15, the output shaft of the first motor 15 drives the abrasive belt 12 to rotate through the abrasive belt tensioning wheel 11. The rotation of the abrasive belt 12 on the two abrasive belt fixing wheels 10 and the abrasive belt tensioning wheel 11, and under the action of the tensioning spring 14, the abrasive belt 12 can be arched and automatically tightened. The output shaft of the first motor 15 also drives the wheel 17 thereon to rotate. When the wheel 17 rotates, it can drive one end of the connecting rod 19 to rotate, so that the equipment carried on the arc-shaped slide plate 4 can synchronously swing back and forth along the trajectory of the center of the arc-shaped fixed slider 3. This reciprocating swing can make the sanding belt 12 contact and grind with the outer contour of the barbell nut while also grinding the upper and lower corners of the barbell nut, so that the rounded corners polished are smoothly tangent to the edge of the barbell nut on three sides, so that there is no obvious edge line on the edge of the barbell nut in visual effect, and the barbell nut will not feel obvious edges when it is gripped and twisted, and the user can fit the barbell nut more closely to the human skin.

[0063] Furthermore, the barbell nut on the pneumatic inner chuck 44 is driven to rotate by the loading robot arm 45, so that the barbell nut can drive the profiling roller 24 to move through its own concave and convex, and the moving profiling roller 24 can always fit the outer contour of the barbell nut under the action of the profiling tension spring 28. At the same time, the movement of the profiling roller 24, under the action of the rack 25 and the second gear 27 in the automatic profiling motion component, enables the moving block 2 and the swing grinding component thereon to move synchronously in a mirror image. Through a series of operations of the automatic profiling motion component, the swing grinding component The sanding belt 12 can be evenly polished along the contour of the barbell nut. Under the action of the rack 25 and the second gear 27 in the automatic profiling motion component, the moving block 2 and the swinging polishing component thereon can also move synchronously in a mirror image. Through a series of operations of the automatic profiling motion component, the sanding belt 12 on the swinging polishing component can be evenly polished along the contour of the barbell nut, which can make barbell nuts of different sizes and different contours can be evenly polished, and each barbell nut can also be effectively controlled in trajectory when the corners are polished.

[0064] Furthermore, by being able to move simultaneously along the contour of the barbell nut through the swinging and polishing assembly, the first sliding plate 16 on the swinging and polishing assembly will drive the inclined slide bar fixing frame 30 and the inclined slide bar 31 on the cooling and cleaning assembly to move synchronously, and the synchronously moving inclined slide bar 31 can drive the inclined slider 33 to move along the trajectory of the inclined slide groove rail 32, so that the cooling sponge 35 on the sponge fixing plate 34 can also move in accordance with the outer contour of the barbell nut, and the water outlet of the water storage dropper bottle 36 can continuously drip cooling cleaning liquid, and the cooling cleaning liquid wets the cooling sponge 35 through the connecting water pipe 37. While the cooling sponge 35 moves in accordance with the outer contour of the barbell nut, the cooling cleaning liquid is evenly applied to the outer contour of the barbell nut, which can enable the cooling sponge 35 to clean up the iron filings and other impurities attached to the rounded surface of the barbell nut after being polished for one circle, and at the same time, the cooling cleaning liquid in the cooling sponge 35 cools the polished rounded surface of the barbell nut.

[0065] Furthermore, when the arc-shaped slide plate 4 on the swinging grinding component swings back and forth in synchronization with the center trajectory of the arc-shaped fixed slider 3, it can also drive the arc-shaped dust nozzle 39 on the dust nozzle fixing plate 38 in the uniform dust removal and cleaning component to swing synchronously, and the activation of the dust suction component 43 can suck air into the arc-shaped dust nozzle 39 through the dust suction hose 41 and the connecting pipe 40, thereby sucking away and collecting the powder splashed out when the sanding belt 12 grinds the barbell nut.

[0066] 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.
