Abstract
The utility model discloses a detaching tool for a pin shaft. the detaching tool is composed of a knock handle (4), a slide hammer (3) and a slide rod (2), wherein the slide hammer (3) is provided with a central hole and is sleeved on the slide rod (2); a front-end screw (1) is arranged at the front end of the slide rod (2); the knock handle (4) is arranged at the rear end of the slide rod (2); and a screw thread is arranged on the front-end screw (1). The pin shaft is pulled out in a vibrating way by virtue of the reverse knock of the slide hammer. The tool is light in mass, convenient for movement and operation, and capable of reducing the labour intensity of workers, lowering the limit of a detaching space on the detaching operation during detachment of the pin shaft, and enabling the detachment of the pin shaft to be flexible, thus saving the detaching time and improving the working efficiency; the tool has the advantages of being simple in structure, convenient for operation, high in accuracy, and low in damage degree of a mechanical surface; and therefore, the tool is very good for being popularized and implemented.
Description
Technical field
The utility model belong to International Classification of Patents B25B be used for fastening, connect, dismounting or clamping tools or bench device technology or device, especially a kind of bearing pin extracting tool.
Background technology
The bearing pin of lathe plays a part to connect, fix in each critical piece of lathe.Lathe at first need be dismantled bearing pin going wrong when needing repairing.If bearing pin can not take apart timely, can't change the parts such as gear, bearing of lathe, thereby influence the processing of parts.
Openly correlation technique is less; For example number of patent application 200920257749 bearing pin extracting tools comprise cover plate and screw, are provided with a through hole at the cover plate center; The band cap lag screw coupling more smaller than through-hole diameter is set in this through hole; Around through hole, be evenly equipped with at least two screws simultaneously, said each screw that is uniformly distributed with has two line at least through said through hole center, and coupling is equipped with the thrust screw in each screw.
Summary of the invention
The purpose of the utility model provides a kind of bearing pin extracting tool.
The goal of the invention measure that realizes the utility model is: the bearing pin extracting tool constitutes by knocking handle, sliding hammer and slide bar; Sliding hammer has centre bore to be socketed on the slide bar; The slide bar front end has preceding terminal screw, and handle is knocked in the slide bar rear end, on the preceding terminal screw screw thread is arranged.Sliding hammer can be moving in the slippage of slide bar glazing.
The advantage of the utility model is, utilizes sliding hammer oppositely to knock, the bearing pin of extricating oneself from a predicament and brace oneself up to action.The instrument light weight is convenient to move and operation, can reduce working strength of workers, and the withdrawal space is to the restriction of this dismounting behavior when reducing the dismounting bearing pin; And make that the bearing pin dismounting is more flexible; Thereby save the take-down time, increase work efficiency, have simple in structure; Easy to operate precision is high, the little advantage of damage mechanical surface degree, is beneficial to very much promotion and implementation.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the joint design sketch map that changes the outfit in the utility model.
Reference numeral comprises: preceding terminal screw 1, slide bar 2, sliding hammer 3, knock handle 4, the nut 5 that changes the outfit, the joint 6 that changes the outfit, screw 7 changes the outfit.
The specific embodiment
Below in conjunction with specific embodiment, describe:
The utility model bearing pin extracting tool constitutes by knocking handle 4, sliding hammer 3 and slide bar 2, and sliding hammer 3 has centre bore to be socketed on the slide bar 2, and slide bar 2 front ends have preceding terminal screw 1, and handle 4 is knocked in slide bar 2 rear ends, on the preceding terminal screw 1 screw thread is arranged.Sliding hammer 3 can be moving in slide bar 2 glazing slippages.The quality of sliding hammer 3 is more than or equal to the quality of knocking handle 4.To guarantee that sliding hammer 3 produces enough kinetic energy when slide bar 2 slides to the inertia that knocks handle 4 and bump takes place.
The screw thread of preceding terminal screw 1 cooperates with nut 5 screw threads that change the outfit at joint 6 rear portions that change the outfit, and on the screw 7 that changes the outfit of joint 6 front ends that change the outfit screw thread is arranged.
After the utility model was used, the time of dismounting bearing pin shortened 50%, and has further shortened the maintenance time of lathe.And be convenient to the narrow and small bearing pin of the withdrawal space.
The go forward diameter of the screw 7 that changes the outfit on diameter and the joint 6 that changes the outfit of terminal screw 1 of slide bar 2 is different.The effect of joint 6 of changing the outfit is, through terminal screw 1 before selecting to use or the screw 7 that changes the outfit to cooperate the diameter and the screw thread of bearing pin outer end centre bore.
The utility model is specifically actual according to the bearing pin of lathe, and promptly generally there is the screw thread of different-diameter at center, bearing pin outer end, in use; Through selecting to use preceding terminal screw 1 or changing the outfit diameter and the screw thread of screw 7 with cooperation bearing pin outer end centre bore; Preceding terminal screw 1 or the screw 7 of changing the outfit are screwed in bearing pin outer end centre bores connect fixingly, manually with sliding hammer 3 backup front end screws 1 before the slide bar 2, manually afterburning then the dial-out makes sliding hammer 3 slide fast to knocking handle 4 along slide bar 2 then; Sliding hammer 3 slides to along slide bar 2 and knocks handle 4; Bump taking place and produce the enough moment kinetic energy that outwards moves with inertia, transmit backward through slide bar 2, and overcomes and be added in fastening frictional force on the bearing pin; When this kinetic energy is enough big, is about to bearing pin and outwards extricates oneself from a predicament and brace oneself up to action.
The utility model has avoided adjacent components such as pin roll end face and case lid impaired through using specific purpose tool dismounting bearing pin, has guaranteed the integrity of bearing pin, has prolonged the service life of lathe.
In above embodiment, do not reach the safety of narration, and mounting technique, and the employing prior aries such as other necessary technologies that relate to enforcement, enumerate detailed description no longer successively.
