Working principle: the first step: the tray 206 is connected into the clamping groove 205, the first motor 201 is started to drive the transmission belt 203 to move so as to convey the tray 206 forwards, the first motor 201 stops operating after each time of conveying the tray 206 for one unit, after bolts exist above the fixing mechanism 4, the third motor 410 is started to drive the rotary table 412 to rotate for one hundred eighty degrees, so that the side, far away from the center of the rotary table 412, of the annular groove 413 is rotated to the upper side, the shifting clamp 407 is driven to move upwards through connection of the second inserting column 409 and the annular groove 413, the sleeve 417 is driven to move upwards through the first inserting column 408, the clamping plates 424 are lifted to enable the clamping plates 424 to overturn and clamp the outer side of the placing bin 208, the placing bin 208 is vertically clamped through the three-side clamping plates 424 so as to clamp and fix the bolts transported to the fixing mechanism 3, the polishing mechanism is convenient to polish the bolts in a threaded manner, the three clamping plates 424 are matched with the bolt heads, the clamping stability is enabled, and the connection stability of the device is improved.
And a second step of: through the design of sphere 428 on splint 424, when the centre gripping position of splint 424 meets the prism of bolt head, prism edge and sphere 428 contact then makes sphere 428 twist reverse with pole 429 as the axle under the pressure of centre gripping this moment to drive the prism of bolt head and skid, make the bolt deflection, thereby supplementary bolt carries out the righting, makes bolt head plane adaptation splint 424 centre gripping, improves the effect of the supplementary righting centre gripping of device.
And a third step of: through the design of sphere 428 on splint 424 to can make the plane centre gripping of bolt self-adaptation torsion adaptation splint 424, thereby can place at will when the staff places the bolt in putting storehouse 208, improve the material loading convenience of device.
Fourth step: through the connection of the upper port of a connecting section of thick bamboo 423 and the outer side of the upper end of a first connecting arm 421 to when splint 424 upset clamping bolt, second connecting arm 425 drives the upper end of a first connecting arm 421 to deflect outwards, struts the upper port of a connecting section of thick bamboo 423, can just in time accomodate the piece that the bolt was polished when falling, can effectually collect the piece, makes the operational environment of device cleaner.
Fifth step: but after the fixing mechanism 4 clamps the head of the bolt, the tail of the bolt is positioned between the two cylinder posts 307, the cutting knife 314 can be driven to approach the tail of the bolt by adjusting the electric telescopic post 313, the second motor 304 is started, the cylinder posts 307 on two sides are driven to rotate by the transverse plate 306, when the cylinder posts 307 rotate, the second gear 311 is meshed with the first gear 303, so that the second gear 311 is driven to rotate, the disc 312 moves downwards along the threaded post 310, the cutting knife 314 polishes the tail of the bolt, the bristles on the right side are arranged on the cutting knife 314, dust in a thread gap can be brushed away by the bristles in time after the left side cutting knife 314 polishes, in addition, after the cutting knife 314 moves to the lower end, the cutting knife 314 is driven to return by the overturning of the second motor 304, the threads can be polished roughly when the cutting knife 314 moves downwards, and the threads are polished finely when the cutting knife 314 moves upwards, so that the polishing quality of the threads is improved.
Sixth step: when the cylinder 307 rotates, the baffle 309 always follows the rotation, flying scraps generated by polishing can be blocked by the baffle 309 through the existence of the baffle 309, splashing of scraps can be avoided, and scraps can be guided to the inside of the cylinder 423 at the lower side through the blocking of the baffle 309, so that the capability of isolating scraps of the device is improved.
Seventh step: through the design of tray 206 overlap joint on draw-in groove 205, after the bolt is polished by grinding machanism 3, the continued movement of conveyer belt 203 then can make tray 206 break away from with draw-in groove 205 in the front side, through the existence of unloading mechanism 5 this moment, can make the front end overlap joint of tray 206 in the upside of jamb 503 to follow the continuous motion of conveyer belt 203 gradually to jamb 503 removal, through the existence of tray 206 like this for the decline of bolt and tray 206 is more stable, improves the safety of device unloading.
Eighth step: after the tray 206 is completely conveyed onto the side pillars 503, the tray grooves 207 and the pushing grooves 209 are just matched with the side pillars 503 and the middle pillars 502, so that the tray 206 automatically sinks onto the lower inner wall of the blanking tray 501, meanwhile, bolts are stamped upwards by the existence of the middle pillars 502, the bolts can be deflected to the right side through the inclined design of the upper end faces of the middle pillars 502, and finally blanking is carried out through the lower rails 506, so that the blanking separation and automatic blanking capabilities of the device are improved.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
