Description
Technical field
The utility model relates to a kind of fitter's bench indexing mechanism.
Background technology
Product is all made up of several part and assemblies.According to the technical requirement of regulation, several parts are bonded into parts or several part and assemblies are bonded into the labout process of product, be called assembling.The former is called that parts assemble, and the latter is called general assembly.It generally comprises the work such as assembling, adjustment, inspection and test, application, packaging.
Assembling is normally carried out on the table, existing fitter's bench can only carry out assembly manufacturing to a kind of part usually, complete an Assembly of the parts usually to carry out on multiple fitter's bench, between multiple fitter's bench, transfer needs the time, so can stop over assembling progress.
Utility model content
For the defect that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of fitter's bench indexing mechanism that can complete part processing on a fitter's bench.
For achieving the above object, the technical solution of the utility model is:
Fitter's bench indexing mechanism, comprise support and workbench, also be provided with cylinder, main shaft, tooth bar, gear, ratchet, ratchet and ratchet post, described main shaft lower end is rotatably connected on support, described gear and ratchet are all connected on main shaft, the piston rod of described cylinder connects tooth bar, and rack and pinion engagement, described workbench is connected to main shaft upper end, described ratchet circumference is at least provided with two described ratchets be evenly arranged, ratchet is connected on the table by described ratchet post, ratchet and ratchet post are rotationally connected, extension spring is provided with between ratchet one end and support, the ratchet other end is pressed on ratchet surface.
When adopting technique scheme, part assembles on the table, control cylinder air inlet, when the piston rod of cylinder stretches out or shrinks, band carry-over bar moves, wheel and rack engages, so rack drives pinion rotation, gear and ratchet are all connected on main shaft, main shaft lower end is rotatably connected on support, so main axis drive ratchet to rotate together, when ratchet drives ratchet to rotate together, workbench also rotates thereupon, and when cylinder band carry-over bar oppositely moves, tooth bar then drives ratchet to rotate backward, now only has pawl wheel, and ratchet is motionless, now workbench remains static, so far workbench just completes a transposition, the piston rod of cylinder moves back and forth, just can continue to drive workbench transposition, until an Assembly of the parts completes.The utility model take cylinder as power source, and control workbench transposition with ratchet and pawl, part often goes to a position, and just complete the operation of an assembling, until assembled, such part just can complete assembling on a workbench.
Further, described tooth bar is provided with limited block, and support is provided with the projection coordinating limited block.Tooth bar moves to limited block and projection when offseting, and namely tooth bar stops mobile, can ensure positioning precision like this.
Further, described limited block is embedded on tooth bar.Can produce collision between limited block and projection, the limited block be embedded on tooth bar also can remain invariant position when being collided.
Further, described gear is all connected with main shaft key with ratchet.The mode that key connects is simple, and installation and removal are convenient.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model fitter's bench indexing mechanism embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: support 1, ratchet 2, ratchet 3, workbench 4, main shaft 5, ratchet post 6, extension spring 7, gear 8, limited block 9, cylinder 10, tooth bar 11, projection 12.
As shown in Figure 1, a kind of fitter's bench 4 indexing mechanism, comprise support 1 and workbench 4, also be provided with cylinder 10, main shaft 5, tooth bar 11, gear 8, ratchet 3, ratchet 2 and ratchet post 5, main shaft 5 lower end is rotatably connected on support 1, gear 8 and ratchet 3 are all connected on main shaft 5, the piston rod of cylinder 10 connects tooth bar 11, and tooth bar 11 engages with gear 8, workbench 4 is connected to main shaft 5 upper end, ratchet 3 is circumferentially with two ratchets be evenly arranged 2, ratchet 2 is connected on workbench 4 by ratchet post 5, ratchet 2 and ratchet post 5 are rotationally connected, extension spring 7 is provided with between ratchet 2 one end and support 1, ratchet 2 other end is pressed on ratchet 3 surface.
In the present embodiment, tooth bar 11 is provided with limited block 9, and support 1 is provided with the projection 12 coordinating limited block 9.Tooth bar 11 moves to limited block 9 when offseting with projection 12, and namely tooth bar 11 stops mobile, can ensure positioning precision like this.
Limited block 9 is embedded on tooth bar 11.Can produce collision between limited block 9 and projection 12, the limited block 9 be embedded on tooth bar 11 also can remain invariant position when being collided.
Gear 8 and ratchet 3 are all connected with main shaft 5 key.The mode that key connects is simple, and installation and removal are convenient.
Specific works principle:
Part assembles on workbench 4, control cylinder 10 air inlet, when the piston rod of cylinder 10 stretches out or shrinks, band carry-over bar 11 moves, gear 8 engages with tooth bar 11, so tooth bar 11 driven gear 8 rotates, gear 8 and ratchet 3 are all connected on main shaft 5, main shaft 5 lower end is rotatably connected on support 1, so main shaft 5 rotates and drives ratchet 3 to rotate together, when ratchet 3 drives ratchet 2 to rotate together, workbench 4 also rotates thereupon, and when cylinder 10 is with carry-over bar 11 oppositely to move, tooth bar 11 drive ratchets 3 rotate backward, ratchet 3 is now only had to rotate, and ratchet 2 is motionless, now workbench 4 remains static, so far workbench 4 just completes a transposition, the piston rod of cylinder 10 moves back and forth, just can continue to drive workbench 4 transposition, until an Assembly of the parts completes.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
