Abstract
The utility model relates to an overhaul tool of the equipment fixing part, in particular to a multifunction pin puller. The problem of the difficult taking out of the locating pin of the present various devices is solved. The multifunction pin puller is characterized in that it comprises a guide arm, a hammer cylinder, a compacting spiral piece, a locking sleeve and a pressing pin cylinder. A boss is arranged at one end of the guide arm. The other end of the guide arm is threaded connected with the pressing pin cylinder. The hammer cylinder clearance fit with the guide arm can be sliding connected below the guide arm boss. The compacting spiral piece threaded connected with the guide arm is arranged in the center lower part of the guide arm. The locking sleeve clearance fit and sliding connected with the guide arm is provided between the pressing pin cylinder and the compacting spiral piece. The inner cavity of the locking sleeve is in inverted cone shape. The external shape of the pressing pin cylinder is matched with the locking sleeve. The pressing pin cylinder is arranged in the locking sleeve after locking. A pin hole is arranged on the top. The utility model can be applied to the locating pin disassembly of the mechanical devices of train, hoist, steam boat, etc.
Description
Technical field: the utility model relates to a kind of service kit of equipment positioning element, particularly a kind of multi-functional pin removal.
Background technology: many positions are all fixed by alignment pin on the variable-speed motor that uses on the DD80t locomotive that Railways Stations is now moved, because these alignment pin position are special, different sizes has brought many inconvenience for on-the-spot maintenance, prolongs the time of maintenance greatly.
Because these alignment pins require institute limit because of design technology, the position is narrow and small, and different sizes can only lean on pliers and hammer to pull out and strike when maintenance at ordinary times, but when not having impetus to make to overhaul very painstakingly with time-consuming.
Summary of the invention: the purpose of this utility model provides a kind of multi-functional pin removal, solve the present repair time long, operating efficiency is low, the problem that the maintenance safety coefficient is low.The technical solution of the utility model is: a kind of multi-functional pin removal, by guide rod, the hammer tube, compress sea whelk, locking sleeve, the pad tube is formed, one end of guide rod has a boss, the guide rod other end adopts with the pad tube and is threaded, the hammer tube adopts matched in clearance with guide rod, slidably be connected guide rod boss below, compressing sea whelk is threaded with the guide rod employing, be installed in the guide rod middle and lower part, locking sleeve and guide rod adopt matched in clearance slidably to be connected, and the installation site is at the pad tube and compress in the middle of the sea whelk, the locking sleeve inner chamber is a back taper, pad tube profile and locking sleeve coupling are positioned at locking sleeve after the locking, head has pin hole.The beneficial effects of the utility model are: (1) is shortened the repair time greatly and is improved the upkeep operation safety coefficient.(2) can select the pad tube according to the size of pulling out alignment pin at any time, a general pad tube goes for the multiple alignment pin (cylinder alignment pin, circular cone alignment pin) such as not of uniform size in the certain size scope, after guide rod and the independent combination of hammer tube, can be used as the puller of PT pump plunger simultaneously, play multi-functional effect.(3) because this instrument is light small and exquisite, use flexibly, can play good effect for narrower and small place, position on some plant equipment.
Description of drawings:
Accompanying drawing is the utility model structural representation sketch
Among the figure: guide rod-1, hammer tube-2, compress sea whelk-3, locking sleeve-4, pad tube-5, boss-6.
The specific embodiment: with reference to accompanying drawing, the annexation of each parts is:
A, guide rod 1 adopt with pad tube 5 and are threaded.
B, hammer tube 2 adopt matched in clearance with guide rod 1, can slide up and down hammering.
C, compress sea whelk 3 and guide rod 1 and adopt and be threaded, be installed in the guide rod middle and lower part.
D, locking sleeve 4 adopt matched in clearance to slide up and down with guide rod 1, and the installation site is at pad tube 5 and compress sea whelk 3 centres.
Principle: this instrument is clamped alignment pin by pad tube 5, and acts on locking sleeve 4 and the pad tube 5 by compressing sea whelk 3, and pad tube 5 is firmly clamped alignment pin, utilizes the upwards principle of hammering boss 6 inertia of hammer tube 2 to carry out work again.Boss 6 is a cylindrical body, is convenient to processing.
The course of work: with pad tube 5 alignment pin is clamped, with locking sleeve 4 pad tube 5 is clamped then, will will compress sea whelk 3 by spanner again and compress locking sleeve 4 and pad tube 5, utilize again hammer tube 2 upwards the inertia that produce of hammering boss 6 alignment pin is extracted.
Estimate feasibility and prospect that the utility model is applied: can be suitable on the alignment pin of size, can be adapted in the dismounting of the suitable alignment pin of plant equipment such as train, loop wheel machine, steamer, not only time saving and energy saving with multi-functional pin removal dismounting alignment pin, and can use in narrower place in the space for maintenance place.
Claims (2)
1, a kind of multi-functional pin removal, it is characterized in that: by guide rod, the hammer tube, compress sea whelk, locking sleeve, the pad tube is formed, one end of guide rod has a boss, the guide rod other end adopts with the pad tube and is threaded, the hammer tube adopts matched in clearance with guide rod, slidably be connected guide rod boss below, compressing sea whelk is threaded with the guide rod employing, be installed in the guide rod middle and lower part, locking sleeve adopts matched in clearance slidably to be connected with guide rod, is installed in the pad tube and compresses in the middle of the sea whelk, the locking sleeve inner chamber is a back taper, pad tube profile and locking sleeve coupling are positioned at locking sleeve after the locking, head has pin hole.
