Abstract
The invention provides a manual auxiliary support. Fixing bolts are arranged on the periphery under a base. A guide hole is vertically formed in the middle of the base. An ejector rod is arranged in the guide hole in a matched mode. A spring is arranged under the ejector rod. The ejector rod stretches out of the base from the guide hole. A clamping sleeve used for clamping an opening is also arranged in the guide hole. The ejector rod is installed in the clamping sleeve in a matched mode. A locking screw corresponding to the clamping sleeve is arranged on the side wall of the base. A positioning hole is formed in the side wall of the clamping sleeve. A fixing screw matched with the positioning hole is arranged on the side face of the base. A cover plate is arranged at the top of the base. The ejector rod stretches out of the cover plate. An adjustment bolt is arranged at the bottom of the spring. An air outlet is further formed in the position, on the lower portion of the ejector rod, of the side wall of the base. According to the manual auxiliary support, the ejector rod has a floating supporting effect relative to the spring, the locking purpose can be achieved manually through surface contact of the clamping sleeve, and convenience and rapidness are achieved; the manual auxiliary support is mainly used for designing clamps for poor-rigidity parts such as thin-walled parts and parts in irregular shapes, rapid fixing and installing are achieved, the structure is simple, and the manual auxiliary support is economical and practical.
Description
Technical field
The present invention relates to frock clamp, specifically Manual auxiliary support.
Background technology
Flywheel current shell series products much has the design in oil sump face, easily comparatively large because hang position when causing turning seam face, does not support again, cause turning seam face to shake line and flatness overproof.In order to solve this kind of problem, usually can only adopt and increasing the rigidity of clamping system hanging the method increasing elasticity supplemental support below position, avoid shaking the flatness that line and part cause because cutting force distortion poor.Also be like this for processing thin-walled part and part in irregular shape.So present supplemental support more and more applies to jig Design.Supplemental support is divided into again hydraulic auxiliary support, pneumatic auxiliary supporting and Manual auxiliary support.
The Element Design turning attachment that thin-wall part and local hang supporting surface is all the supplemental support purchasing the U.S. " Jie Gensi ", but it has 3 shortcomings.1. expensive, each auxiliary price 3100 yuan; 2. Jie Gensi Manual auxiliary support adopts vice fastening, and the contact surface of clamp system is little, causes clamping force less, so the nut that must screw up with a wrench could lock resiliency supported nail, adds the amount of labour of workman, reduces production efficiency; 3. find that Jie Gensi Manual auxiliary support support nail when locking has the rising of 0.015mm by actual measurement, this distortion upwards that will part caused to produce 0.015mm, thus 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 built-up jig in machinery industry 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, preventing from being out of shape, before processing float support can be placed on below workpiece and to utilize the compression of back-moving spring B, making the automatic close contact workpiece of float support axle.Rotation lock screw, promotes locking skewback, makes the fin of locking skewback slide in the groove of float support main shaft, the inclined-plane of locking skewback can be allowed to be adjacent to the inclined-plane of float support main shaft all the time by the compression of back-moving spring A.Like this, the support force of vertical direction can be provided the bottom surface of workpiece to be machined, improve machining accuracy and the quality of workpiece to be machined.
Be utilize lock-screw in this patent, promote locking skewback, make the fin of locking skewback slide in the groove of float support main shaft, the inclined-plane of locking skewback can be allowed to be adjacent to the inclined-plane of float support main shaft all the time by the compression of back-moving spring A.Although the use of locking skewback can lock float support main shaft, but the external force needed is larger, namely need the state by the locking of instrument guarantee, quick-replaceable object is not reached for quick-replaceable float support, moreover because the External Force Acting of instrument can cause the phenomenon of sideslip equally during the instrument of use, so easily cause for converted products size sideslip especially, be that thin-wall part and local hang the part of supporting surface.
Summary of the invention
The present invention is intended to the cost reducing Manual auxiliary support, and facilitates the operation of workman, enhances productivity and ensures product quality, special proposition Manual auxiliary support.
Technical scheme of the present invention 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: coordinate in pilot hole and be provided with push rod, spring is equipped with in the bottom of push rod; Push rod reaches base in pilot hole, is wherein also provided with chuck in pilot hole, and push rod coordinates installation in chuck, and on the sidewall of base, corresponding clip is arranged with lock-screw.
The improvement of such scheme is: chuck is axially arranged with clamping opening.
The improvement of such scheme is: on chuck sidewall, be provided with locating hole, and is provided with hold-down screw at the side-fit locating hole of base.
The improvement of such scheme is: be provided with cover plate at the top of base, push rod stretches out from cover plate.
The improvement of such scheme is: the bottom of spring is provided with adjusting bolt.
The improvement of such scheme is: the sidewall of the base of push rod bottom is also provided with venthole.
Beneficial effect:
Push rod of the present invention plays the effect of float support relative to spring, chuck is used 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, thus jack-up part can be avoided when ensureing push rod locking, better ensure the flatness in part milling face, the effect of lock-screw to chuck simultaneously makes push rod reach the effect of face contact, only by the very little object that manually just can reach locking, convenient and swift.
Chuck be axially arranged with clamping openings the compression of lock-screw and locking.
Chuck sidewall is provided with locating hole, and is provided with hold-down screw at the side-fit locating hole of base.Ensure that chuck angle is located, can ensure that chuck angular turn does not occur, make lock-screw be pressed in the vertical direction of chuck opening direction all the time, after making chuck stress deformation, whole Cylindrical Surfaces Contact push rod, produces maximum frictional force, ensures to hold push rod tightly.
The top of base is provided with cover plate, and push rod stretches out from cover plate, and cover plate assembling axial gap that is rear and chuck is very little, ensures that chuck does not have large play.
Adjusting bolt can regulate according to the height in workpiece support face, ensures that push rod can contact workpiece in the state of upspringing, adds the scope of application of supplemental support.
The setting of venthole is the effect of exhaust outlet, ensures that push rod moves up and down not by air pressure impacts, and discharges ponding smoothly.Proved by Long-Time Service, support nail moves flexibly, not by the impact of cutting night and dirt.
The present invention is mainly used in the part of the poor rigidity such as thin-wall part and the jig Design of part in irregular shape, and manually can realize fixing and installation fast, structure simple economy is practical.
