Description
Technical field
The utility model relates to a kind of mechanical disassembling fixture, specifically relates to a kind of pin specific purpose tool that unloads.
Background technology
Pin mainly is to be used for fixing two relative positions between the assembly parts, perhaps realizes the connection etc. between the assembly parts, all is interference fit between the general and assembly parts, after pin tightens, is difficult to.For for convenience detach, general pin upper end is all with the thread groove with internal thread.Generally be with iron hammer pin to be launched when common assembling or maintenance die, perhaps extract with the Simple pin puller of homemade screw welding that because the screw model is too small, it is firm that solder side is difficult to welding.The frequent phenomenon of the disconnected screw of You order in the ordinary maintenance mold process has a strong impact on the operating efficiency of die assembly and maintenance.Just during the mould in produced on-site is used, in case send out the problem of giving birth to the disconnected screw of order, the employee must all unload mould from equipment, waste time and energy, and has had a strong impact on employee's operating efficiency in maintenance.
For solving the technical problem of damaging easily screw and pin when existing pin pulling tool is dismantled pin, publication number is that the patent documentation of CN201325031 discloses a kind of pin pulling tool, comprise spanner, play nail piece and support member, wherein playing nail piece has comprised the nail piece head and has played nail piece bar section, spanner is inner hexagon spanner or outer hexagonal spanner, playing the nail piece head is a hexagon socket head section that can cooperate with spanner or outer-hexagonal head, playing nail piece bar section is a cylindrical bar, its lower end circumferential surface be provided with can with the external screw thread of the screw-internal thread fit of pin, support member comprises support member via hole and the support member pit that communicates up and down, the diameter of support member via hole is little compared with the diameter of nail piece head, diameter compared with nail piece bar section is large, and the internal diameter of support member pit is larger than the diameter of pin head.The technical problem that this pin pulling tool has damaged assembly parts and pin, has been unfavorable for repeating to install assembly easily when having solved existing pin pulling tool dismounting pin is applicable to rising of cylindrical pin with internal thread and taper pin with internal thread and pulls out, and is reusable, easy to operate.
But there is following defective in the disclosed pin pulling tool of above-mentioned patent documentation: (1) is played nail piece and can not be changed, and can only be used for the dismounting of the pin of a kind of model and the degree of depth, poor practicability.When (2) playing in addition the nail piece damage, need integral replacing, increased use cost.
The utility model content
The utility model provides a kind of pin specific purpose tool that unloads, this tool making cost is low, easy to use, dog screw adopts and removably connects, convenient according to the suitable dog screw of the specification different choice of pin, be convenient for changing simultaneously the dog screw of damage, improved the service life of unloading the pin specific purpose tool.
A kind of pin specific purpose tool that unloads comprises connecting rod, the coaxial dog screw that is arranged on this connecting rod one end and the block stamp that is slidingly matched with described connecting rod, and connecting rod is provided with the block stamp locating part; Described dog screw is threaded with described connecting rod.
The regioselective screw is threaded with described connecting rod, made things convenient for the replacing of dog screw, the size of the pin that can dismantle is according to actual needs selected suitable dog screw, has improved versatility of unloading the pin specific purpose tool of the present utility model, has reduced simultaneously use cost.
The capable of choosing multiple mode is threaded described dog screw with connecting rod, for ease of processing, a kind of preferred technical scheme is: described connecting rod threaded one end is combined with attachment cap, the end face of this attachment cap has through hole, the screw portion of described dog screw runs through this through hole, and the nut of dog screw partly is subject between described connecting rod and the attachment cap.General and the dog screw accessory processing of attachment cap, complete replacing during replacing guarantees the stability in the dog screw use procedure.
For improving the service life of block stamp, guarantee simultaneously to have stronger impulsive contact force in the block stamp use procedure, described block stamp is metal sleeve, metal sleeve is provided with the spacing ring that matches with described block stamp locating part near an end inwall of dog screw.Spacing ring can arrange separately, also can with the machine-shaping of metal sleeve one.
The block stamp locating part is used for two extreme positions that the restriction block stamp slides, for ease of processing, preferred block stamp locating part comprises and is fixed on described connecting rod back to the limited post of an end of dog screw and the positive stop lug boss that is arranged on the connecting rod middle part that described spacing ring is between limited post and positive stop lug boss.Under the acting in conjunction of limited post and positive stop lug boss, spacing ring reciprocatingly slides at limited post and positive stop lug boss connecting rod between the two, and then the sliding distance of control block stamp.Can select between positive stop lug boss and the connecting rod to be wholely set, the positive stop lug boss that also can select to make in advance is fixedly connected on the body of rod of described connecting rod.Can select between limited post and the connecting rod to be wholely set, also limited post can be made in advance, and then fix with the connecting rod respective end.For ease of replacing and the dismounting of block stamp, described limited post is threaded with described connecting rod.When selection is threaded, can be chosen in described limited post center screwed hole is set, in the corresponding end of connecting rod thread groove is set, utilize bolt that both are fixed and get final product.Under the effect that guarantees larger impulsive contact force, for further reducing block stamp to the wearing and tearing of positive stop lug boss, can select the external diameter of close block stamp one end of described positive stop lug boss greater than the external diameter of the other end.
For preventing the dog screw double swerve described in the unloading process, the down suction between the down suction between described metal sleeve inwall and the limited post and described spacing ring and the described connecting rod is 0.5-1mm.This excesssive gap, block stamp reciprocatingly slide in the process, and connecting rod shakes easily, cause the dog screw location inaccurate or turn round bad dog screw; The gap is too small, then causes easily block stamp and connecting rod card jail, causes unloading process to carry out smoothly.
Form cavity between block stamp spacing ring, block stamp inwall and limited post and the connecting rod outer wall, in the block stamp impact event, because the down suction between spacing ring and the described connecting rod is that 0.5-1mm is less, in the high speed impact event, gas in the cavity has little time to discharge, and the capitate that can liquidate becomes certain resistance.Be the air drag of avoiding forming, a kind of preferred technical scheme is that described limited post outer wall is provided with air slot.The degree of depth that air slot arranges can be determined according to the size of actual tool itself.
For preventing in the use procedure, the staff landing, can select described metal sleeve back to an end of dog screw with flanging.For further increasing the frictional force between block stamp and the staff, can be chosen in described block stamp outer wall anti-skidding projection or anti-slip tank are set.
The pin specific purpose tool overall structure of unloading of the present utility model is simple, easy to use, the employing of helicitic texture, be convenient to the replacing of dog screw, improved the versatility of this specific purpose tool, and this instrument overall dimensions is less of some space-constrained occasion use, and cost of manufacture is low, easy to maintenance, long service life.
