Abstract
The utility model discloses a device for fitting an elastic cylindrical pin in a half-shaft pin hole in a pressing way. The device comprises two parts, namely a press fitting structure and a supporting seat structure, wherein the press fitting structure comprises a pressure head (3), an air cylinder (1) and a nut (2); the upper part of the pressure head (3) is in a cylindrical structure; the air cylinder (1) is sleeved in the pressure head (3); the nut (2) is sleeved on the top of the pressure head (3) in a penetrating way; the bottom of the pressure head (3) is provided with an elastic pressing mechanism which comprises a steel ball (4) and a first spring (5) and is used for clamping the elastic cylindrical pin (6); the center of the upper part of the supporting seat (7) is provided with a semi-circular groove; the supporting seat (7) is internally provided with a positioning pin (8) and a second spring (9) which are used for limiting a half shaft hole site. The device disclosed by the utility model can be used for conveniently and fast fitting the elastic cylindrical pin in the pressing way in the half shaft pin hole and ensures the press fitting quality.
Description
Technical field
The utility model relates to the elastic cylindrical pin press mounting tool in a kind of power industry semiaxis assembling.
Background technology
In the assembling of power industry semiaxis, need in semiaxis circular hole radially, press-fit elastic cylindrical pin.Existing assembly method is that semiaxis is placed on the platform, with hammer elastic cylindrical pin is pounded in the semiaxis hole.This method causes the elastic cylindrical pin bending easily, and the end distortion is followed the string; Pound into the length inequality, inefficiency, assembling is inconvenient; And the assembling safety coefficient is low.
Summary of the invention
The utility model mainly provides a kind of device that can press-fit elastic cylindrical pin in the semiaxis pin-and-hole.
The technical solution adopted in the utility model is: a kind of device that press-fits elastic cylindrical pin in the semiaxis pin-and-hole, formed by press mounting structure and seat structure two parts, press mounting structure is made up of pressure head, cylinder and nut, pressure head top is tubular structure, cylinder jacket is contained in the pressure head, and nut is set on the pressure head top.The pressure head bottom is provided with the elastic compression mechanism that is made up of steel ball, first spring, is used for the clamping elastic cylindrical pin.The seat structure central upper portion is a half slot, is provided with alignment pin and second spring in the bearing, is used for limiting position, semiaxis hole.During use, elastic cylindrical pin is penetrated in the pressure head, steel ball compresses elastic cylindrical pin under the pressure effect of first spring, semiaxis is put in the half slot of bearing, and with alignment pin limiting hole position, is started cylinder elastic cylindrical pin is pressed in the semiaxis hole.By adjusting the position of nut and pressure head, can regulate the length that elastic cylindrical pin is pressed into semiaxis.
The device that the utility model provides can press-fit elastic cylindrical pin quickly and easily in the semiaxis pin-and-hole, guarantee to press-fit quality.
Description of drawings
Accompanying drawing 1 press-fits the cross-sectional view of the device of elastic cylindrical pin in the semiaxis pin-and-hole for the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, cylinder 2, nut 3, pressure head 4, steel ball 5, first spring 6, elastic cylindrical pin 7, bearing 8, alignment pin 9, second spring
As shown in Figure 1, the utility model press-fits the device of elastic cylindrical pin and is made up of press mounting structure and seat structure two parts in the semiaxis pin-and-hole, press mounting structure is made up of cylinder 1, nut 2 and pressure head 3, nut 2 and pressure head 3 are sleeved on the cylinder 1 successively, pressure head 3 is tubular structure, pressure head 3 bottoms are provided with the elastic compression mechanism that is made up of steel ball 4, first spring 5, are used for clamping elastic cylindrical pin 6.Bearing 7 central upper portion are a half slot, are provided with alignment pin 8 and second spring 9 in the bearing 7.
Carrying out elastic cylindrical pin when press-fiting, elastic cylindrical pin 6 is penetrated in the pressure head 3, adjust the position of nut 2 and pressure head 3, can regulate the length that elastic cylindrical pin is pressed into semiaxis.Steel ball 4 compresses elastic cylindrical pin 6 under the pressure effect of first spring 5, semiaxis is put in the half slot of bearing 7, and with alignment pin 8 limiting hole positions, starting cylinder 1 can be pressed into elastic cylindrical pin 6 in the semiaxis hole.
Claims (1)
1. device that in the semiaxis pin-and-hole, press-fits elastic cylindrical pin, it is characterized in that: formed by press mounting structure and seat structure two parts, press mounting structure is by pressure head (3), cylinder (1) and nut (2) are formed, pressure head (3) top is tubular structure, cylinder (1) is sleeved in the pressure head (3), nut (2) is set on pressure head (3) top, pressure head (3) bottom is provided with by steel ball (4), the elastic compression mechanism that first spring (5) is formed, be used for clamping elastic cylindrical pin (6), bearing (7) central upper portion is a half slot, is provided with alignment pin (8) and second spring (9) in the bearing (7).
