Description
Technical field
The utility model relates to a kind of pin pulling tool, especially a kind of pin removal that can extract pin shaft from lathe belongs to
In small tool technical field.
Background technique
It is frequently necessary to take out movable axis, direct selling or taper pin from lathe during machine upkeep at present, this just needs to make
With specific purpose tool --- pin removal.Traditional pin removal needs to make pin puller head, and pin puller head both ends are external screw thread, one
End is connect with pin removal, then the other end and axis connection to be pulled pin are extracted pin shaft using the effect of inertia of weight on pin removal.
Since shaft diameter to be pulled pin is not of uniform size, pin puller head also needs that plurality of specifications is made, to be applicable in the axis to be pulled pin of different size,
Not only make it is cumbersome, it is at high cost, and pin puller head it is small in size and more and disorderly, be easily lost, often spent in machine upkeep
Plenty of time finds pin puller head, and labor efficiency is low.Further, since there is the axis to be pulled pin of multiple and different specifications on lathe, repair
A whole set of pin puller head need to be taken when lathe, use is extremely inconvenient.
Utility model content
The purpose of the utility model is to provide a kind of structures simple, at low cost, easy to use, versatile multi-functional to pull out
Sell device.
The utility model is achieved by the following technical programs:
A kind of Multifunction pin puller, including pin removal ontology, weight and special joint piece；The pin removal ontology is rod piece
Structure, for the weight sliding sleeve in the middle part of pin removal ontology, the special joint piece is fixedly set in pin removal ontology one end
On, special joint piece outer end laterally extends V-type deck, lateral kidney slot is additionally provided in the middle part of special joint piece, laterally
Kidney slot is located on the inside of V-type deck, and V-type deck home record is communicated with the lateral kidney slot, when pulling pin, clamping in the middle part of bolt of pulling pin
On V-type deck home record, bolt head of pulling pin is located in lateral kidney slot.
The purpose of this utility model can also be further realized by following technical measures.
Multifunction pin puller above-mentioned, wherein the pin removal ontology other end is equipped with flange of pulling pin.
Multifunction pin puller above-mentioned, wherein the V-type deck bottom semicircular fluted shaft line and pin removal body axis is same
Axis.
Multifunction pin puller above-mentioned, wherein the weight periphery is equipped with annular knurl.
Multifunction pin puller above-mentioned, wherein the special joint piece is connect with pin removal ontology threaded one end.
The utility model special joint piece replaces traditional pin puller head, and structure is simple, at low cost.When extracting pin shaft,
Bolt is screwed in into axle thread hole to be pulled pin, is then blocked in the middle part of bolt with the V-type deck of special joint piece, at this time bolt head position
In in lateral kidney slot, while slide weight rapidly to flange direction of pulling pin along pin removal ontology, and hit
It pulls pin flange, under weight effect of impact power, axis to be pulled pin can smoothly be extracted from lathe, and use is very convenient.Due to V-type
Deck home record is gradually increased from bottom to top, and the utility model is allowed to extract respective diameters specification by the bolt of plurality of specifications
Pin shaft, it is versatile, it is applied widely, substantially increase labor efficiency, still can be by traditional pin removal in certain specific occasions
Head is screwed pulls pin on the threaded hole of pin removal ontology both ends, and the utility model can also make when crowbar during machine upkeep
With, it is vdiverse in function, great convenience is brought to machine upkeep.
The advantages of the utility model and feature will carry out diagram reconciliation by the non-limitative illustration of preferred embodiment below
It releases, these embodiments, is only provided as an example referring to attached drawing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A of Fig. 1 to partial enlarged view；
Fig. 3 is the B of Fig. 1 to partial enlarged view.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 2 and Figure 3, the utility model includes pin removal ontology 1, weight 2 and special joint piece 3.It pulls pin
Device ontology 1 is member structure, and 2 periphery of weight is equipped with annular knurl 21, and 2 sliding sleeve of weight is on 1 middle part of pin removal ontology, specially
Pass through threaded engagement on 1 right end of pin removal ontology with connector 3, outer end laterally extends upward V-type deck 31, V-type card
311 axis of half slot and 1 axis coaxle of pin removal ontology of 31 bottoms of seat, special joint piece are additionally provided with lateral kidney-shaped in 3 middle part
Slot 32, lateral kidney slot 32 are located at 31 inside of V-type deck, and 31 home record of V-type deck is communicated with lateral kidney slot 32, when pulling pin, pulled out
It is connected on 31 home record of V-type deck in the middle part of pin bolt, bolt head of pulling pin is located in lateral kidney slot 32.Pin removal ontology 1 is left
End is equipped with flange 11 of pulling pin, and is respectively equipped with M10 threaded hole 12 and M12 threaded hole 13 in the middle part of 1 both ends end face of pin removal ontology, can connect
Traditional pin puller head of two kinds of specifications is connect, it is applied widely.
