Abstract
The utility model belongs to the field of mechanical dismounting, specifically relates to a dismounting device for die fixed pin, comprising a stroke lever, an impact hammer, a left nut, a left screw and a right nut, wherein the stroke lever is sleeved by the impact hammer; the left end of the stroke lever and one end of the left nut are in a threaded connection; and the other end of the left nut is connected to the left screw by welding; the right end of the stroke lever and one end of the right nut are in a threaded connection. The utility model has advantages of simple structure, convenient and fast use; satisfying the dismounting of fixed pins in different types.
Description
Technical field
The utility model belongs to mechanical dismounting field, is specifically related to a kind of provision for disengagement of screw die steady pin.
Background technology
At present, in plant equipment field-strip process, the dismounting that relates to steady pin is more frequent.Two kinds of steady pin one stocks: a kind of is disposable steady pin, and it has endoporus; Another kind is the screw die steady pin, and it has endoporus and screw thread, can repeatedly use.But because the screw die steady pin adopts interference fit to be connected with the fixed support axis hole, connect very tight between the two, and do not have relative motion between screw die steady pin and axis hole, between easily produce corrosion, these factors have brought very large difficulty for the dismounting of screw die steady pin.For example, when the vehicle maintenance operation, one has dual mode the dismounting of screw die steady pin, the one,, use this vehicle dedicated fixed pin dismounting to draw tool, utilize the axial tension that rotation produced of screw thread that steady pin is taken out, but the use of the method still needs by other aids, and under the situation that runs into the pin-and-hole corrosion, only rely on the axial tension that screw thread produced of steady pin, still be difficult to steady pin is taken out; The 2nd,, under the situation of not using removal tool special, behind dismounting wheel hub dust cover,, steady pin to be pounded out from the outside at steady pin outside pad one object less than axis hole, this kind mode is time and effort consuming not only, and damages the internal thread of steady pin easily.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to use, provision for disengagement efficiently.
To achieve these goals, the technical solution of the utility model is: a kind of provision for disengagement of steady pin, it is characterized in that it comprises stroke lever, jump bit, left nut, left screw rod, right nut, sheathed jump bit on the stroke lever, the left end of stroke lever adopts with an end of left nut and is threaded, the fixing left screw rod of other end welding of left side nut, the right-hand member of stroke lever adopts with an end of right nut and is threaded.
It also comprises right screw rod the provision for disengagement of steady pin, and right screw rod is weldingly fixed on the termination of right nut away from stroke lever.
The aperture while of described jump bit is less than the external diameter of left nut and right nut.
The bar footpath smooth surface of described stroke lever, two ends are provided with external screw thread.
The model of a left side screw rod and right screw rod can be selected for use according to the size of the inner bolt hole of steady pin, and therefore, the utility model device can satisfy the dismantlement work of different model steady pin.
Compared with prior art, the utlity model has simple in structure, easy to use, characteristics efficiently, replaceable because of screw rod (with nut), can satisfy the dismantlement work of different model steady pin.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Description of symbols among the figure: 1-left side screw rod, 2-left side nut, 3-jump bit, 4-stroke lever, the right nut of 5-, the right screw rod of 6-.
The specific embodiment
In order to understand the utility model better, below in conjunction with embodiment and accompanying drawing the technical solution of the utility model is further described, referring to Fig. 1:
Press the provision for disengagement of a kind of steady pin of the utility model enforcement, it comprises stroke lever 4, jump bit 3, left nut 2, left screw rod 1, right nut 5, sheathed jump bit on the stroke lever (jump bit can be free to slide on stroke lever), the left end of stroke lever adopts with an end of left nut and is threaded, the fixing left screw rod of other end welding of left side nut, the right-hand member of stroke lever adopts with an end of right nut and is threaded.The utility model can also comprise right screw rod 6, and right screw rod is weldingly fixed on the termination of right nut away from stroke lever.
The aperture of jump bit is simultaneously less than the external diameter of left nut and the external diameter of right nut.
The model of a left side screw rod and right screw rod can be selected for use according to the size of the inner bolt hole of steady pin.
One comprises following use step the utility model:
1) type selecting: the size of the inner bolt hole of Chai Xie steady pin is selected the left screw rod of correspondingly-sized for use as required, and it is mounted on the left end of stroke lever, in the inner bolt hole of the steady pin of more left screw rod rotation being packed into;
2) disassembling section: jump bit is slided to left nut one side, with external force make jump bit rapidly to the right nut one side slide and knock right nut, the momentum pulling steady pin that utilizes the jump bit hammer body to impact to be produced moves back and forth according to this, takes out until steady pin.
Described protection domain of the present utility model is not limited to the above embodiments, and other technical scheme identical with the utility model essence all belongs to the scope of the utility model protection.
