The specific embodiment
Below in conjunction with accompanying drawing the present invention is done clear, intactly explanation:
See also Fig. 1 and Fig. 2, this hydraulic automatic riveter comprises being used to drive and revolves revolving riveting post drive system assembly and being used for the workpiece clamp clamping system assembly of clamping work pieces of riveting post.Saidly revolve that riveting post drive system assembly comprises that Pressure gauge leaves 1 pass, Pressure gauge 2, revolves riveting motor 3, revolves riveting hydraulic cylinder assembly 4, fastening screw nut 5, stroke adjustment nut 6, die cap assembly 7 and revolve riveting post 8 etc.Said workpiece clamp clamping system assembly comprises clamping cylinder assembly 9, is used for the clamping device of clamping work pieces 20, electric appliance control box 14, workbench 15, fuel tank working cabined 16, Electric Machine at Pumping Station 17, liquid level gauge 18, front clamp piece 19, clamp lead 21, column 22, overflow valve 23, solenoid directional control valve 24, revolve riveting flow speed control valve 25, clamping cylinder seat 26 and filler cap 27 etc.
See also Fig. 3, and combine to consult Fig. 1 and 2, this clamping device that is used to clamp workpiece 20 to be riveted comprises clamping upper bolster 10 and clamping die shoe 13.Workpiece 20 is placed on the said clamping die shoe 13.The top of said clamping upper bolster 13 is fixedly connected with clamping cylinder assembly 9 efferents, and clamping cylinder assembly 9 efferents drive clamping upper bolster 13 and move up and down, so that clamping work pieces 20.The top of said clamping die shoe 13 is provided with one and is used to prop up the workpiece locating piece 12 that workpiece 20 tail end faces make location, workpiece front and back.The head of said workpiece 20 is with to revolve riveting post 8 relative.The bottom of said clamping upper bolster 13 sets gradually some clamps from workpiece 20 heads to caudal directions.In the present embodiment, said clamp has two, comprises front clamp piece 19 and back clamp 11, and the head of relative workpiece 20 and middle part are provided with respectively.Accordingly, said clamping die shoe 13 is provided with two back-up blocks, back-up block 28 and back back-up block 29 before comprising.And said back-up block 28,29 and said clamp 19,11 corresponding settings.A plurality of clamps 19,11 and back-up block 28,29 clamping work pieces 20 are set, can make the clamping force of clamping work pieces 20 be distributed to each one of workpiece.Certainly, be evenly distributed on the workpiece 20, preferably above-mentioned clamp 19,11 relative workpiece 20 vertically evenly be provided with in order to make workpiece 20 suffered clamping forces.And clamp and back-up block are many more, and dispersion effect is good more.
When needs are riveted workpiece 20, earlier workpiece 20 is placed on back-up block 28,29 tops that clamp die shoe, and makes the afterbody of workpiece 20 be attached to the front end of workpiece locating piece 12.Then, start workpiece clamp clamping system assembly, make the clamping upper bolster 10 of clamping device under the drive of clamping cylinder assembly 9, move down until with clamping die shoe 13 clamping work pieces 20.Because correspondence is provided with some clamps and back-up block successively on clamping upper bolster 10 and clamping die shoe 13, makes the clamping force that clamps 10 pairs of workpiece 20 of upper bolster be distributed to each clamp and gets on.Certainly, if clamp 19,11 vertically evenly setting of workpiece 20 relatively, the dispersion effect of clamping force is better.So, avoided too concentrating and cause workpiece 20 surfaces to produce impression, thereby effect has been protected workpiece to the clamping force of workpiece 20.Then, start and revolve riveting post drive system assembly, drive the head that revolves 8 pairs of workpiece 20 of riveting post and rivet.Because clamp 19,11 and back-up block 28,29 vertically disperse to be provided with at workpiece 20, feasible clamping force to workpiece 20 is disperseed, and clamps better effects if, and more family firmly can prevent that workpiece from the moment of riveting, producing distortion.Therefore, can control the size of workpiece 20 effectively, improve product percent of pass, and then effectively enhance productivity.
The present invention is simple in structure; Easy to use; Through disperseing to be provided with some compact heaps successively and some back-up blocks be set from workpiece head to afterbody in the top correspondence that clamps die shoe in the bottom that clamps upper bolster; Make clamping force be distributed on the workpiece, thereby avoid surface of the work to produce impression, effectively protect the surface of workpiece through clamp and back-up block.Simultaneously, because clamping force is distributed on the workpiece, feasible more firm to the clamping of workpiece, in workpiece riveted joint process, workpiece is not easy to produce distortion, thereby, can the dimensional accuracy of workpiece be controlled in the scope of requirement, effectively control the quality of product.
Though the present invention discloses as above with preferred embodiment, so it is not in order to limit the present invention.Have common knowledge the knowledgeable in the technical field under the present invention, do not breaking away from the spirit and scope of the present invention, when doing various changes and retouching.Therefore protection scope of the present invention is as the criterion when looking claims person of defining.
