Description
Technical field
The utility model relates to frock clamp, specifically Manual auxiliary support.
Background technology
Flywheel current shell series products much has the design of oil sump face, easily larger because hang position while causing turning seam face, does not support again, causes turning seam face shake line and flatness overproof.In order to solve this class problem, conventionally can only adopt and increase the rigidity that the method for elasticity supplemental support increases clamping system below position hanging, avoid shaking line and part because of the flatness that cutting force distortion causes poor.For processing thin-walled part and part in irregular shape, be also like this.So supplemental support more and more applies to jig Design now.Supplemental support is divided into again hydraulic auxiliary support, pneumatic auxiliary supporting and Manual auxiliary support.
The supplemental support that thin-wall part and the local Element Design turning attachment that hangs supporting surface are all the buying U.S. " Jie Gensi ", but it has 3 shortcomings.1. expensive, 3100 yuan of each auxiliary prices; 2. Jie Gensi Manual auxiliary support adopts vice fastening, and the contact-making surface of clamp mechanism is little, causes clamping force less, so the nut that must screw up with a wrench could be locked resiliency supported nail, has increased workman's the amount of labour, has reduced production efficiency; By actual measurement find Jie Gensi Manual auxiliary support when locking support nail have the rising of 0.015mm, this will cause part to produce the distortion making progress of 0.015mm, thereby cause the flatness of accessory turning at least to increase the error of 0.015mm.
Application number: 201210254108.4 applyings date: 2012-07-23, a kind of mechanical floating for machinery industry built-up jig supports, and comprising: float support main body, float support axle, locking skewback, lock-screw, bolt, back-moving spring A, back-moving spring B.When workpiece be combined fixture fixing after, in order to make workpiece reduce vibrations in machining, prevent from being out of shape, can float support be placed on below workpiece before processing and utilize the compression of back-moving spring B, make the automatic close contact workpiece of float support axle.Rotation lock screw, promotes locking skewback, and the fin of locking skewback is slided in the groove of float support main shaft, and the compression by back-moving spring A can allow the inclined-plane of locking skewback be adjacent to the inclined-plane of float support main shaft all the time.Like this, can to the bottom surface of workpiece to be machined, provide the support force of vertical direction, promote machining accuracy and the quality of workpiece to be machined.
In this patent, be to utilize lock-screw, promote locking skewback, the fin of locking skewback is slided in the groove of float support main shaft, the compression by back-moving spring A can allow the inclined-plane of locking skewback be adjacent to the inclined-plane of float support main shaft all the time.Although the use of locking skewback can be locked float support main shaft, but the external force needing is larger, namely need to be by the state of instrument guarantee locking, for quick-replaceable float support, do not reach quick-replaceable object, moreover the External Force Acting due to instrument can cause the phenomenon of sideslip equally while using instrument, so easily cause for the sideslip of converted products size especially, be thin-wall part and the local part that hangs supporting surface.
Summary of the invention
The utility model is intended to reduce the cost of Manual auxiliary support, and facilitates workman's operation, enhances productivity and guarantees product quality, the special Manual auxiliary support that proposes.
The technical solution of the utility model is for this reason, and Manual auxiliary support comprises base, and the surrounding under base is provided with set bolt, and the centre of base is vertically provided with pilot hole, it is characterized in that: in pilot hole, coordinate and be provided with push rod, spring is equipped with in the bottom of push rod; Push rod reaches base in pilot hole, wherein in pilot hole, is also provided with chuck, and push rod coordinates installation in chuck, and on the sidewall of base, corresponding clip is arranged with lock-screw.
Improvement to such scheme is: chuck is axially arranged with clamping opening.
Improvement to such scheme is: on chuck sidewall, be provided with locating hole, and coordinate locating hole to be provided with hold-down screw in the side of base.
Improvement to such scheme is: the top at base is provided with cover plate, and push rod stretches out from cover plate.
Improvement to such scheme is: the bottom of spring is provided with adjusting bolt.
Improvement to such scheme is: on the sidewall of the base of push rod bottom, be also provided with venthole.
Beneficial effect:
The utility model push rod plays the effect of float support with respect to spring, use chuck to implement to lock clamping to push rod, due to lock-screw contact is chuck, chuck is held tightly and is made push rod can not produce play upwards, thereby while guaranteeing push rod locking, can avoid jack-up part, better guarantee the flatness of part milling face, lock-screw makes push rod reach the effect of face contact to the effect of chuck simultaneously, only with very little, manually just can reach the object of locking, convenient and swift.
Chuck be axially arranged with clamp openings compression and the locking of lock-screw.
On chuck sidewall, be provided with locating hole, and coordinate locating hole to be provided with hold-down screw in the side of base.Guaranteed chuck angle location can guarantee that angular turn does not occur chuck, made lock-screw be pressed in all the time the vertical direction of chuck opening direction, made whole Cylindrical Surfaces Contact push rod after chuck stress deformation, produced maximum frictional force, guaranteed to hold tightly push rod.
The top of base is provided with cover plate, and push rod stretches out from cover plate, and cover plate assembling end play rear and chuck is very little, guarantees that chuck does not have large play.
Adjusting bolt can regulate according to the height of workpiece support face, guarantees that push rod can contact workpiece at the state of upspringing, and has increased the scope of application of supplemental support.
The setting of venthole is the effect of exhaust outlet, guarantees that push rod moves up and down not affected by air pressure, and discharges ponding smoothly.By long-term use, prove, support nail moves flexibly, is not cut the impact of night and dirt.
The utility model is mainly used in the jig Design of part and the part in irregular shape of the poor rigidity such as thin-wall part, manually can realize fixing and installation fast, simple in structure economical and practical.
