Further, the lock screw driving motor is stepper motor.

Compared to the prior art the present invention, has the following advantages and effect：The driving motor that circulates is supported by the first circulation Roller and the second circulation backing roll drive circulation back(-)up belt action, workpiece to be fed forward under the drive of circulation back(-)up belt, the One photoelectric sensor and the second photoelectric sensor detect workpiece motion s to the first photoelectric sensor and the second photoelectric sensor When surface, the first Y-direction cylinder movement of the first Y-direction positioning component drives the positioning elastic force offset plate movement of the first Y-direction, realization pair The Y-direction of workpiece right over the first photoelectric sensor positions, and the first X drives the first X to the first X of positioning component to cylinder It is acted upwards to position block, realizes the X to the workpiece right over the first photoelectric sensor to positioning, the second Y-direction positions Second Y-direction cylinder movement of component drives the positioning elastic force offset plate movement of the second Y-direction, realizes to being located at the second photoelectric sensor just The Y-direction of the workpiece of top positions, and the 2nd X drives the 2nd X to be acted upwards to position block to the 2nd X of positioning component to cylinder, The X to the workpiece right over the second photoelectric sensor is realized to positioning, L-type circulates the realization of back(-)up belt bracket to workpiece Z-direction supports.Then, oscillatory type screw feeding machine acts, and screw is supplied to from screw feeder channel in tripper bearing one by one, point Expect that cylinder drives sub-material pushing block reciprocating action, screw is staggeredly sent into the first inlet and the of the lower end of tripper bearing one by one Two inlets, screw passes through corresponding feeder sleeve under pull of vacuum from corresponding feed connection mouth, and connects from corresponding material feeding Mouth is connect into corresponding screw for spray gun, and enter vertical processing groove from corresponding feeder channel.Then, screw driving motor is locked The rotation of the first transmission shaft is driven by the first synchronous pulley, synchronous belt and the second synchronous pulley, in the first synchromesh gear and second Under the transmission of synchromesh gear, second driving shaft and the rotation of the first transmission shaft synchronous backward, the first synchromesh gear and the second synchronous gear Wheel is helical gear, and engagement registration is high, and noise is small, and service life is long, is conducive to improve transmission stability.First active umbrella tooth Wheel, the second driving bevel gear, third driving bevel gear and the 4th driving bevel gear respectively by the first driven bevel pinion, second from Dynamic bevel gear, third driven bevel pinion and the 4th driven bevel pinion drive first gear axis, second gear axis, third gear shaft and 4th gear shaft rotates, because the first transmission shaft and second driving shaft rotation direction are on the contrary, the first driving bevel gear, the second active Bevel gear and third driving bevel gear, the 4th driving bevel gear installation direction on the contrary, so first gear axis, second gear axis, Third gear shaft and the 4th gear rotational axis direction are identical.First gear axis, second gear axis, third gear shaft and the 4th Gear shaft passes through the first universal drive shaft, the second universal drive shaft, third universal drive shaft, the 4th universal drive shaft, respectively One screwdriver bit connecting shaft, the second screwdriver bit connecting shaft, third screwdriver bit connecting shaft and the 4th screwdriver bit connecting shaft drive the first screwdriver, second Screwdriver, third screwdriver and the 4th screwdriver fast rotation, lifting cylinder drive lifting sliding table to be moved downwards along lifting column Make, after the first screwdriver bits, the second screwdriver bits, third screwdriver bits and the 4th screwdriver bits touch workpiece, lower carrier plate connects Spindle is compressed along linear bearing upward sliding, lower carrier plate spring, the first screwdriver, the second screwdriver, third screwdriver and 4th screwdriver is by screw-driving on workpiece.It is provided with dust cover on the outside of first synchronous pulley and the second synchronous pulley, institute It states and is also equipped with dust cover on the outside of the first synchromesh gear and the second synchromesh gear, realize and the first synchronous pulley, second are synchronized The protection of belt wheel, the first synchromesh gear, the second synchromesh gear, substantially increases transmission stability, improves service life.Lock spiral shell Silk driving motor is stepper motor, and the rotating speed of stepper motor, the position of stopping are solely dependent upon the frequency and umber of pulse of pulse signal, Without being influenced by load variation, be conducive to accurately controlling for screw tightening torque.After processing is completed, lifting cylinder drives lifting Slide unit acts upwards along lifting column, and Multihead lock set screw assembly resets.As circulation back(-)up belt continues to act, process Workpiece continues onwards transmission, realizes blanking.The present invention can not only realize that synchronizing for Multi-head screw tightens installation, and workpiece can be real Existing automatic loading/unloading, does not need specific fixture, enormously simplifies structure, improve the degree of automation of equipment, improve life Produce efficiency.
