Rack side plate fixed axis two ends riveting clamp
Technical field
The utility model relates to axle two ends riveting mechanism, specifically discloses a kind of rack side plate fixed axis two ends riveting clamp.
Background technology
Bracket component (as Fig. 3) is the core component in my company KFM2 breaker, is related to product quality and production efficiency.This component parts is more, complex structure, more difficult during assembling, first needs to solve riveted joint orientation problem, and employee can be allowed fast and accurately parts to be put into fixture.Secondly because of follow-up matching requirements, after the riveted joint of this procedure, what the flange of axle will be tried one's best in midair puts down, and can not protrude too many, and this is also needed to increase the manual reason beaten out together in the past.The depth of parallelism ensureing biside plate is also needed in addition after riveted joint.
Be that employee rivets two ends (in Fig. 3 A place) for twice respectively for a long time always, beat out with hammer again after riveted joint.Inefficiency, labour intensity is large, and when employee's hammer beats out, power is difficult to control, and easily support is struck distortion.In order to ensure quality and the good operating efficiency of product, need to design the frock clamp meeting companies ask.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and 2, rack side plate fixed axis two ends riveting clamp, comprises chuck body 1, is provided with punch-head assembly and fixes 2,3 above and below described chuck body 1, overall in I shape; Also comprise punch-head assembly, described punch-head assembly has two groups, is distributed in the both sides of described chuck body, symmetrical; Described punch-head assembly comprises the upper punch assembly be fixed on upper punch assembly fixed head 2 and the low punch assembly be fixed on low punch assembly fixed head 3, and described upper punch assembly and low punch assembly are on same axial line.Punch-head assembly distributes in pairs and punch-head assembly coordinates up and down, can be fixed axle riveted joint simultaneously, and simultaneously to support both sides fixed axis synchronous riveting, greatly can increase work efficiency to two bracket components.
Described upper punch assembly comprises curling punch 4, upper reset spring 5, stop collar 6 and upper precompressed rubber 7, described upper curling punch 4 one end is punching press end, the other end is end of exerting pressure, and its punching press end, through described upper punch assembly fixed head 2, is socketed described upper precompressed rubber 7 outside end; Its end of exerting pressure is for bearing the pressure coming from press; Described upper reset spring 5 is for the reset after the punching press of upper curling punch 4, be socketed on curling punch 4, be positioned at above described upper punch assembly fixed head 2, exerting pressure to hold at upper curling punch 4 is provided with for the limiting plate spacing to upper reset spring 5, namely add lifting surface area, can prevent again upper reset spring 5 from axially departing from; Described stop collar 6 is arranged at outside upper reset spring 5, is fixed on described upper punch assembly fixed head 2, itself and described upper reset spring 5 partly overlap, namely to ensure effective punching press length on curling punch vertical direction, prevent the left and right sidesing shifting of curling punch 4 and upper reset spring 5 again.Described upper curling punch 4 punching press end (as Fig. 4) in intermediate projections, surrounding is circular groove structure, its bossing exceeds described upper curling punch 4 punching press end end face, ensures the turnup of fixed axis end volume to the greatest extent; Described upper curling punch 4 punching press end bossing is lower than described upper precompressed rubber 7 end plane, and in guarantee, precompressed rubber 7 plays pre-compressed effect.
Described low punch assembly comprises Rolldown hem drift 8, lower precompressed thimble 9 and lower back-moving spring 10, described low punch assembly fixed head 3 inside is provided with low punch assembly lock chamber 11, described Rolldown hem drift 8 one end abuts with low punch assembly lock chamber 11 inside, maintain static, the other end is punching press end, and it extends described low punch assembly lock chamber 11; Described lower precompressed thimble 9 pivot bush unit is on described Rolldown hem drift 8, and one end is connected in low punch assembly lock chamber 11, and the other end extends to outside low punch assembly lock chamber 11, pumps in whole punching course; Described lower back-moving spring 10 for the reset before and after the punching press of lower precompressed thimble 9, it is positioned at low punch assembly lock chamber 11, be socketed on described Rolldown hem drift 8, with described lower precompressed thimble 9 end abutment.Described Rolldown hem drift 8 punching press end (as Fig. 4) in intermediate projections, surrounding is circular groove structure, its bossing exceeds described Rolldown hem drift 8 punching press end end face, ensures the turnup of fixed axis end volume to the greatest extent; Described Rolldown hem drift 8 punching press end bossing, lower than described lower precompressed thimble 9 end plane, ensures that lower precompressed thimble 9 plays pre-compressed effect.
Being equipped with of upper precompressed rubber 7 and lower precompressed thimble 9 is the riveted joint depth of parallelism in order to ensure part and does not have gap between riveted joint backstage terrace and lateral plates.
As shown in Figure 5, described upper punch assembly and low punch inter-module, described chuck body 1 are provided with the U-shaped location-plate 12 for rack side plate fixed axis location, relevant position structure matching on this U-shaped location-plate 12 structure and support, is placed between upper and lower curling punch 4,8 easily and fast by fixed axis; Support product is diversified in specifications, can be met the demand of riveted joint by the height and position changed in U-shaped location-plate 12 vertical direction.
Rack side plate fixed axis riveting process is as follows:
Whole fixture is ready, gets out each parts of support.First just assembles a collection of parts, put on the table, during riveted joint, bracket component entirety is picked up, then support shaft is aimed at U-shaped location-plate 12 and put into fixture, need position be shifted onto.Now press press button, press presses down, and the precompressed part of upper and lower curling punch 4,8 first touches support biside plate, by biside plate compacting, upper and lower curling punch 4,8 is pressed onto axle in midair immediately, and the tip of drift is carved and opened shaft hollow part, and axle starts crimping riveting and opens immediately.Release button, press is lifted, and upper curling punch 4 rollback immediately under the effect of upper reset spring 5, now takes out bracket component, and check product, put into turnover box, a riveted joint cycle completes.In the process, employee is exterior at board, handling safety.Support has once been riveted after putting into fixture, once completes the riveted joint of upper and lower two riveting points, and efficiency improves, and riveting quality is reliable.
This fixture all available when needing riveted joint to identical similar products fixed axis two ends, for the requirement adapting to different fixed axis length can be realized by the distance changed between upper and lower punch-head assembly, delicate structure, easy to operate, operating efficiency is high.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
