Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
If Fig. 1 is to a kind of automatic localization bolt screwing machine shown in 11, including underframe 1, bearing 3, laser docking facilities and device for screwing up 4, device for screwing up 4 is located at bearing front, underframe 1 top is loading panel 10, bearing 3 is fixed on loading panel 10 upper surface, is additionally provided with horizontal dislodgment feature and vertical racking device between bearing 3 and device for screwing up 4.
Horizontal dislodgment feature: as shown in Figure 5, the lateral driver device 323 moved including horizontal slide rail 320, fixed plate 321 and control fixed plate, lateral driver device 323 is fixed on base plate 310 or bearing 3 surface, fixed plate 321 is slidably connected with horizontal slide rail 320, device for screwing up 4 is fixed on fixed plate surface, and horizontal dislodgment feature is located at kickboard 311 surface;
Kickboard 311 surface is articulated with a circular gear 322, kickboard 311 surface has two fixed plates 321, and fixed plate 321 is equipped with tooth bar, and rack and pinion 322 engages, two fixed plates 321 are moved about gear 322 centrosymmetry by tooth bar, two fixed plates 321 are equipped with and tighten joint 43.When a fixed plate 321 is by lateral driver device 323 mobile, another fixed plate can be driven to move, a purpose controlling multiple device for screwing up 4 can be reached with this, lateral driver device 323 only controls the single fixed plate tightening joint 43 place, by the cooperation of rack and pinion, 2 fixed plates tightening joint 43 place can be controlled simultaneously.
Tighten for two and below joint 43, be equipped with corresponding generating laser, when, in object stage 5 rotation process, two set laser docking facilities all tapped through hole can be sought position and bolt is tightened, and can effectively reduce the probability that tapped through hole cannot be swept to.
As shown in figure 11, it is the carrier surface that can scan of single laser docking facilities, and those tapped through holes that cannot scan, it is only capable of by manually checking, and carries out mending-leakage.
Fixed plate 321 is L-shaped, horizontal slide rail 320 totally two, and each fixed plate 321 is all slidably connected with two horizontal slide rails 320, the most steady safety of sliding process.
In the present embodiment, lateral driver device 323 is fixed on base plate 310 surface, and lateral driver device 323 can be followed vertical racking device and together be moved.
Laser docking facilities includes moving track 62, emitter 60 and receptor 61: receptor 61 is positioned at tightens joint 43 center of rotation, emitter 60 reciprocatingly slides on moving track 62, and emitter 60 followed by emitter and receptor 61 keeps being on same vertical axis.
The position of emitter 60 and receptor 61 can be exchanged, it is contemplated that the volume of generating laser 60 is the hugest, it is difficult to is arranged on and tightens in joint 43, and therefore in the present embodiment, receptor 61 is installed on and tightens in joint 43.
Moving track 62 mainly moves for emitter 60, and the joint 43 of tightening that emitter 60 is followed on horizontal dislodgment feature together moves, and keeps the laser in emitter 60 can be irradiated in receptor 61.
Vertical racking device: include for longitudinal slide rail 300 that front and back shift mechanism vertically moves, control before and after the lifting device 302 of shift mechanism height, balancing weight 303 and runner 301, balancing weight 303 is connected by connector with front and back shift mechanism, runner 301 is positioned at the top of bearing 3, and balancing weight 303 hangs on the two ends of runner 301 with shift mechanism front and back by connector;
Vertical racking device, is first the lifting for device for screwing up 4, is mounted and taken out carrier, next to that provide enough down pressure stroke when pressure tights a bolt down for it for tightening joint 43.
Balancing weight 303 and runner 301 are the weight for balancing both sides, and its principle is similar to elevator, lowering or hoisting gear 302 can be greatly reduced and control the power needed for device for screwing up 4.Lifting device 302 uses cylinder to promote, easy to control.
Being provided with rotatable circular stage 5 in the middle part of loading panel 10, underframe 1 is provided with the rotating driving device rotated for object stage 5 and limits the rotary limit device of object stage 5 rotational angle, and in the middle part of object stage 5, hollow out is arranged.
Rotating driving device is the rotation for driving object stage 5, and motor cooperating teeth roller box or miscellaneous part can be used to realize the rotation of object stage.
Rotary limit device 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 needs a stable restriction, uses the rigid limit safeties such as alignment pin high, but angle Selection is less, carry out spacing according to friction, the stepless changing being capable of multiple angle is spacing, uses friction spacing in the present embodiment, rotates to control it by compressing object stage 5.
The purpose that in the middle part of object stage 5, hollow out is arranged is: reduce its interference to laser docking facilities as far as possible, the present embodiment can use fine steel rib to make up the structural strength lacked in the middle part of object stage, being similar to the spoke of bicycle tyre, carrier can be fixed on fine steel rib by fixture.
As shown in Figure 6 and Figure 7, device for screwing up 4 include for bolt screw tighten joint 43, rotate tighten the rotating mechanism 40 of joint and put into the filler device of bolt for tightening joint.Filler device includes the bolt storage cylinder 41 for placing bolt, moves filling guide thimble 42 for bolt to tightening joint and control the open-close on-off 410 of bolt entrance filling guide thimble;Being additionally provided with before tightening joint 43 can the cap liner 44 of grip bolt.
Bolt storage cylinder 41 is in the tubulose being vertically arranged, for placing the bolt of unified specification to be installed, open-close on-off 410 is for controlling dropping of bolt, when the laser of emitter 60 exposes in receptor, represent there is tapped through hole immediately below device for screwing up, now open-close on-off 410 is opened, and transports bolt to tightening on joint 43, is used for being threaded in through hole.
Loading guide thimble 42 and include cannula inlet port 421 and guide groove 422, cannula inlet port 421 connects with bolt storage cylinder 41, guide groove 422 adapter sleeve tube inlet 421 with tighten joint 43, guide groove 422 is in T-shape groove.
As shown in Fig. 8 to Figure 10, tightening joint 43 in cylinder, tighten and be provided with hexagonal bolt groove 431 in the middle part of joint 43, tighten joint 43 sidewall and be provided with the bolt entered for bolt and join mouth 430, bolt is joined mouth 430 and is connected in T-shape and with guide groove 422.
Loading guide thimble 42 and also include swagelok 420, tighten joint 43 and be sheathed in swagelok 420, swagelok 420 can effectively prevent the joint 43 of tightening of high-speed rotation to be exposed to outside, prevents bolt from flying out, and ensures to be difficult to by people's false touch simultaneously.
After emitter in laser docking facilities and receptor docking, it it is tapped through hole immediately below display, after open-close on-off 410 is opened, bolt enters in cannula inlet port 421, and slip into bolt by guide groove 422 and join mouth 430 and enter and tighten in the bolt groove 431 of joint 43, cap liner 44 will be tightened joint 43 and seal afterwards, only spill the screw portion of bolt, and the nut of bolt is positioned at tightens joint.
Having additional hold-down devices in tightening joint 43, by the nut compressing of bolt on cap liner 44, vertical racking device will be pressed under whole device for screwing up, and is screwed in carrier by bolt, and during being screwed into, cap liner 44 is opened, and enables nut to remove and tightens joint 43.
Driving means following in the present embodiment is all connected with intelligent terminal.
Driving means includes:
Lateral driver device 323 in-horizontal dislodgment feature, for cylinder.
Lifting device 302 in-vertical racking device, for cylinder.
Rotating driving device 51 on-object stage 5, for motor.
