A kind of bolt screwing machine
Technical field
The present invention relates to assembling apparatus, it is a kind of bolt screwing machine。
Background technology
Owing to bolt adopts artificial spanner to tighten, extremely inefficient, speed is excessively slow, waste of manpower。
Bolt screwing machine, is the machine for bolt is screwed into carrier, and its moment of torsion is the fixed value set, and will not there is, as manually tightening, the phenomenon that screwing force is uneven。
Having a class electric wrench (or pneumatic impact spanner) on market, bolt is quickly screwed in carrier by motor etc. by it, and ensure that moment of torsion when tightening is fixed value, but it exists certain shortcoming:
1, first, heavier mass, its operation principle is similar to electric drill, needs certain muscle power for helping and grasp electric wrench during work, keeps electric wrench angle when bolt is screwed into and height, loosely very easily causes that screw thread twists flower once grasp。
2, when the bolt being screwed into is bigger, turn required twisting resistance relatively big, then physical fitness requirement is higher, be therefore not suitable for the worker that strength is more weak, cause the limitation of user。

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further。
If Fig. 1 is to the bolt screwing machine shown in 12, including underframe 1, bearing 3 and device for screwing up 4, device for screwing up 4 is located at bearing front, and underframe 1 top is loading panel 10, and bearing 3 is fixed on loading panel 10 upper surface。
Being provided with rotatable object stage 5 in the middle part of loading panel 10, underframe 1 is provided with mean for the rotating driving device that object stage 5 rotates and the rotary limit device 52 limiting object stage 5 rotational angle。
Rotating driving device 51 is the rotation for driving object stage 5, it is possible to adopt motor cooperating teeth roller box or miscellaneous part to realize the rotation of object stage。
Rotary limit device 52 is the rotation tightening limit object stage for bolt, when preventing screw-driving, carrier is screwed clamp force and drives and fixing shakiness, deflect, therefore rotary limit device 52 needs stable one to limit, therefore it is best for adopting the rigid limits such as alignment pin, carry out spacing according to friction, it is possible to the stepless changing realizing multiple angle is spacing, but still there is certain potential safety hazard。
Rotary limit device 52: as it is shown in fig. 7, comprises spacing fixture block 520, the driving device supplying spacing fixture block 520 reciprocal telescopic and multiple spacing slot 50, spacing slot 50 is distributed in the periphery of circular stage 5。
Spacing fixture block 520 in rotary limit device 52 stretches out under the effect of driving device or enters in spacing slot 50, and spacing slot 50 is according to carrying out needed for actual vector offering multiple spacing slot 50。Owing to, in actual production process, the number of articles that single producer produces is relatively big, and kind is single, and the position that bolt is tightened is also comparatively single, and therefore the limit method of this slot is more stable, it is not necessary to use friction to carry out spacing。
Loading panel 10 surface is additionally provided with the cylinder 100 facilitating loading transport and rotating, and greatly facilitates object stage and rotates, and facilitates workman to transport, places carrier。
Device for screwing up 4: as shown in Fig. 4, Fig. 9 and Figure 11, including rotating mechanism 40 with tighten joint, tightening joint, to include nut pullover, nut is pullover to be rotated by rotating mechanism 40, tightening joint to include seamless and tighten joint 41 and join pressure and tighten joint 42, the rotating mechanism 40 in device for screwing up 4 is connected with intelligent terminal。
Seamless tightens joint 41: as shown in Figure 8 and Figure 9, by nut, pullover 410, rotating mechanism 40 and STATEMENT OF FEDERALLY SPONSORED form, seamless tightens joint 41 needs lifting device 302 in vertical racking device to provide certain downforce for it when screwing bolts, relatively big suitable in downforce degree, and the bolt that pressure stroke is bigger down。
Join pressure and tighten joint 42: as shown in Figure 10 to Figure 12, rotating mechanism 40, STATEMENT OF FEDERALLY SPONSORED pullover 420 including nut, join pressure position limiting structure and drive pullover 420 telescopic movings of nut join pressure device 43;
Join and press pullover 420 ends of nut tightening joint 42 to be polygonal column structure and be slidably connected in STATEMENT OF FEDERALLY SPONSORED 421, STATEMENT OF FEDERALLY SPONSORED 421 and rotating mechanism 40 synchronous axial system, STATEMENT OF FEDERALLY SPONSORED 421 is provided with stopper slot 4210, the pullover end 420 of nut is fixed with spacer pin 4200, and spacer pin 4200 moves back and forth in stopper slot 4210。
Join pressure tighten in joint 42 spacer pin 4200 and stopper slot 4210 coordinate, make nut pullover 420 be only capable of join pressure device 43 effect under in certain stroke reciprocal telescopic, there is position-limiting action。Join pressure device 43 and adopt cylinder, and be connected with intelligent terminal, control to join pressure and the backhaul down of pressure device 43 by cylinder, drive moving back and forth of nut pullover 420。
It is additionally provided with between bearing 3 and device for screwing up 4: front and back shift mechanism, horizontal dislodgment feature and vertical racking device。
