Abstract
The internal thread taper pin dismantling tool consists of one pin drawing bar, one sliding weight mounted onto the pillar of the pin drawing bar via loose fit, and one pull head screwed up to the stud of the pin drawing bar. Through screwing up the pull head selected based on the internal thread taper pin to be dismantled to the pillar, holding the sliding weight in hand and pounding the pin drawing bar upwards with the sliding weight, the internal thread taper pin may be dismantled fast. The internal thread taper pin dismantling tool has the advantages of reliable performance and fast dismantling speed.
Description
Technical field
The present invention relates to hardware ﹠ tools, especially inner screw taper pin dismounting tool.
Background technology
Taper bolt is a securing member commonly used in the machine-building, generally cooperates with bolt to be used for being connected of two parts.After being close to, the faying face that it is vertically mounted on two parts together in the taper hole of articulation, needs 2 taper bolts at regular intervals usually.Because taper bolt and taper hole can be realized not having the gap and cooperate, institute so that the relative position of two parts obtain fixing uniquely.Ressemble after the dismounting, can recover the fixing relative position of two parts exactly by taper bolt.The dismounting of taper bolt generally is it to be launched from its small end with the cylinder instrument, for the taper bolt that is contained in obstructed circular cone pin-and-hole or can't launch from its small end by design of part restriction, just adopt taper pin with internal thread, the big end of this taper bolt has screwed hole, taper bolt is pulled out by screwed hole with corresponding bolts and backing plate.But there are some problems in this method: 1, the concrete structure according to two part combinations will be equipped with bolt and the backing plate that adapts, and the instrument of rotating bolt; 2, because the reach of taper pin with internal thread is limited, the diameter of thread is less, and screw thread may be damaged in unloading process; 3, the take-down time is slower, incompatible than the dismounting of taper pin with internal thread in enormous quantities.
Summary of the invention
The purpose of this invention is to provide a kind of inner screw taper pin dismounting tool, can dismantle taper pin with internal thread easily and fast reliably.
The technical solution adopted for the present invention to solve the technical problems is: knock the pin removal bar that pull head is housed with sliding hammer, utilize to be contained in the taper pin with internal thread screw double-screw bolt on the pull head it is extracted.Extracting tool is made up of pin removal bar, sliding hammer and pull head, and sliding hammer is contained on the small column of pin removal bar, is the bigger cooperation in gap; Pull head is tightened on the double-screw bolt of pin removal bar roundlet styletable, and the small end of pull head is and the identical double-screw bolt of taper pin with internal thread screw screw thread that the big end cylinder of pin removal bar has vertically and pass through the hole of its axis.Be screwed in wherein according to the screw selection pull head of the taper pin with internal thread that will dismantle and its double-screw bolt, hold the sliding big column end face of hammering the pin removal bar of firmly upwards thumping into shape, can pull down taper pin with internal thread fast and reliablely.
The advantage of this inner screw taper pin dismounting tool is: the specification according to taper pin with internal thread disposes corresponding pull head, just can dismantle multiple taper pin with internal thread easily and fast reliably.This inner screw taper pin dismounting tool dependable performance simple to operate, the special dismounting that adapts to taper pin with internal thread in enormous quantities.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Accompanying drawing is the installation diagram of inner screw taper pin dismounting tool.
Fig. 1 is a front view.
Fig. 2 is the A-A profile of Fig. 1.
1. pin removal bars among the figure, 2. sliding hammer, 3. pull head, 4. taper pin with internal thread, 5. loam cake, 6. base.
The specific embodiment
With reference to accompanying drawing, sliding hammer 2 is contained on the small column of pin removal bar 1, is the bigger cooperation in gap, and the small column of the boring ratio pin removal bar 1 of general sliding hammer 2 is big 1～2 millimeter.There is chamfering the upper end in sliding hammer 2 holes that cooperate with pin removal bar 1 small column.For easy to operate, pin removal bar 1 big end cylinder, sliding hammer 2 periphery annular knurls.Pull head 3 is tightened on the double-screw bolt of pin removal bar 1 roundlet styletable, and the big end of pull head 3 is regular hexahedron, and the radial section of the hex nut that its radial section and its internal thread are measure-alike is consistent.The small end of pull head 3 is and the identical double-screw bolt of taper pin with internal thread 4 screw screw threads, pin removal bar 1 big end cylinder has vertically and passes through the hole of its axis, its effect is to cooperate with six sides of pull head 3 big ends with the cylinder that injects this hole to make pull head 3 and the 1 relative rotation of pin removal bar, thereby change pull head 3, make instrument can dismantle the taper pin with internal thread 4 of plurality of specifications.Be to prolong the service life of instrument, pin removal bar 1, sliding hammer 2, pull head 3 adopt can the manufacturing of heat treated high-quality steel and they are heat-treated: pin removal bar and pull head, modified 29-34HRC, the sliding hammer 45～50HRC that quenches.Part loam cake 5, base 6 usefulness bolts and taper pin with internal thread 4 link together.Select pull head 3 and its double-screw bolt is screwed in the screw according to the screw of the taper pin with internal thread 4 that will dismantle, hold firmly the thump big column end face of pin removal bar 1 of sliding hammer 2, can pull down taper pin with internal thread 4 fast and reliablely.Backing out bolt just can separate loam cake 5 with base 6.
The LM24-2C rubber roll husker is to use more hulling machine in the market, the axis designs in the main shaft bearing shell hole of the gear-box of this hulling machine is on the faying face of base 6 and loam cake 5, therefore before processing, just must base 6 and loam cake 5 be fitted together this hole of processing with bolt and taper pin with internal thread 4, again they are taken apart during assembling, so the workload of dismounting taper pin with internal thread 4 is bigger, the method efficient of taper pin with internal thread 4 being pulled out with bolt and backing plate is low, and dismounting is easily with its internal thread damage repeatedly.After adopting inner screw taper pin dismounting tool, pull pin with the knocking mode, speed is fast.Because it is longer that the double-screw bolt of pull head 3 screws in the taper pin with internal thread screw, so the Shi Buhui damage screw of pulling pin.
