Description
Technical field
The utility model relates to mechanical disassembling fixture field, in particular to a kind of detaching device for pin shaft.
Background technology
Bearing pin is one of conventional parts of plant equipment, safeguards, often needs to dismantle bearing pin in repair procedures in plant equipment.At present, the method for dismounting commonly used for bearing pin type component is the method adopting forcing press or manually knock, and complex procedures, wastes time and energy.And the restriction being subject to the condition such as construction site, plant equipment design feature is under many circumstances difficult to bearing pin to pull down, and sometimes also parts can be coordinated to cause damage to it for pulling down.
Utility model content
For above-mentioned problems of the prior art, the utility model provides a kind of and is easy to carry, the detaching device for pin shaft of easy to use, highly versatile.
For achieving the above object, the utility model provides following technical scheme:
The utility model detaching device for pin shaft comprises hammer cover, hammer stem and adapter sleeve, and hammer stem is provided with a boss, and hammer is arranged with a through hole, and through-hole diameter is greater than hammer stem diameter and is less than boss diameter, and hammer cover is sleeved on hammer stem by through hole.Hammer the diameter of diameter more preferably greater than hammer stem boss of cover into shape, to ensure to hammer the impact effect to boss when cover slides to boss along hammer stem into shape.Adapter sleeve one end is fixedly connected with hammer stem, the other end by screw thread be disassembled bearing pin and be connected, screw thread be disassembled bearing pin and match, the adapter sleeve with dimension screw thread is selected in the aperture according to required dismounting bearing pin.The hammer cover both sides parallel with hammer stem are respectively equipped with handle, and hammer overlaps between boss and adapter sleeve, and grip hand propelled hammer cover slides to boss along hammer stem, rely on the hammer cover power acted on boss to be pulled down by bearing pin.Even if under the environment that working space is less, the utility model also can be adopted to be pulled down by bearing pin.
Preferably, detaching device for pin shaft also comprises at least one extension bar, and extension bar one end is fixedly connected with hammer stem, and the other end is fixedly connected with adapter sleeve.So that select the extension bar of different size, varying number and other parts of detaching device for pin shaft to combinationally use according to the size of working space, good environmental adaptability.
Hammer stem and extension bar can be threaded connection, can for being threaded between extension bar with adapter sleeve.This device entirety adopts and is threaded, hammer stem only need be made with extension bar to be connected one end, extension bar two ends, adapter sleeve be connected one end with extension bar and all adopt the screw thread of same specification to realize standardization, change combined and instant, so that according to the difference being disassembled bearing pin pore size, and the difference of working space selects adapter sleeve, the extension bar of different model, be convenient to combination install, highly versatile.
The handle of hammer cover both sides can also arrange fixing hole respectively, and two fixing holes respectively bolt hang with rope.Pull rope that hammer cover can be made to slide to boss and be pulled down by bearing pin.

Detailed description of the invention
The technical solution of the utility model is understood better in order to make those skilled in the art; below in conjunction with accompanying drawing of the present utility model; clear, complete description is carried out to the technical solution of the utility model; based on the embodiment in the application; other roughly the same embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all should belong to the scope of the application's protection.
Embodiment one:
As shown in Figure 1, 2, 3, a kind of detaching device for pin shaft, comprise hammer cover 1, hammer stem 2, extension bar 3 and adapter sleeve 4, described hammer stem 2 is provided with a boss 5, described hammer cover 1 is provided with a through hole 6, through hole 6 diameter is greater than the diameter of hammer stem 2 and is less than the diameter of boss 5, and hammer cover 1 is sleeved on hammer stem 2 by through hole 6, and the diameter of hammer cover 1 is greater than the diameter of boss 5.Described extension bar 3 one end is threaded with hammer stem 2, and the other end is threaded with adapter sleeve 4.Described adapter sleeve 4 other end is provided with the screw thread matched with the screw being disassembled bearing pin 7.Described hammer cover 1 both sides parallel with hammer stem 2 are respectively equipped with handle 8, and handle 8 is respectively equipped with fixing hole 9, two fixing holes 9 respectively bolt hang with rope, and hammer cover 1 is between boss 5 and adapter sleeve 4.Described hammer stem 2 is connected one end with extension bar 3, described extension bar 3 two ends, described adapter sleeve 4 are connected with extension bar 3 screw thread that one end all adopts same specification.The utility model structure is simple, and cost of manufacture is low, and dismounting is simple, easy to carry.Use the utility model dismounting bearing pin simple to operate, and parts will be coordinated to cause damage to bearing pin.And the utility model highly versatile, be applicable to different operating space, the bearing pin of detachable different size.
Before using this device to dismantle bearing pin, first determine the aperture size being disassembled bearing pin 7, select the adapter sleeve 4 matched accordingly, then select the extension bar 3 of appropriate length and quantity according to working space; Be sleeved on by hammer cover 1 on hammer stem 2, the hammer stem 2 chosen, extension bar 3 be connected successively by screw thread with adapter sleeve 4, adapter sleeve 4 other end is connected with bearing pin 7 by screw thread; By two people respectively pulling hammer two ropes overlapped in 1 both sides fixing hole 9 make hammer overlap sweeping action on 1 track formed at hammer stem 2 and extension bar 3, bearing pin 7 is pulled down by the inertia force acted on boss 5 by hammer cover 1.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
