Abstract
The utility model relates to a column pin pressing device, which belongs to the technical field of motor producing and processing. The device comprises a bottom board, wherein a bottom film is fixed on the bottom board, the upper end of the bottom film forms an arc groove whose axial cord is in the horizontal direction, a groove hole for allowing the lower end of a column pin to enter is arranged on the bottom of the arc groove, and a press which is connected on the presser is arranged above the arc groove. The device has simple structure, can improve the manufacturing efficiency, can guarantee the installation quality of the column pin and solves the problems that no device which is specially used for installing the column pins exists in the prior art, and the column pins are installed in the pin holes usually needing the matching of two or more than two people during the assembly, the manufacturing efficiency is lower and the assembling quality is difficult to guarantee and the like in the prior art.
Description
Technical field
The utility model relates to a kind of pressure straight pin device, belongs to the technical field of motor production and processing.
Technical background
Generally, the close-fitting modes that adopt cooperate more between straight pin and the pin-and-hole, as cooperating between the pin-and-hole in the rotating shafts such as straight pin and motor.Because what adopt between straight pin and the pin-and-hole is the close-fitting structure,,, by the mode of knocking or press-fit straight pin is pressed in the pin-and-hole then again with the straight pin alignment pin holes so the axle that needs to be provided with pin-and-hole during assembling is located well.Be not specifically designed to the device that straight pin is installed in the prior art, need during assembling in the pin-and-hole that two or two above cooperations of people could pack straight pin into more, its production efficiency is lower, and is difficult to the installation quality of assurance straight pin.
Summary of the invention
It is a kind of simple in structure that the utility model purpose is to provide, can enhance productivity, can guarantee the pressure straight pin device of the installation quality of straight pin, solved the device that is not specifically designed to the straight pin installation that prior art exists, need during assembling in the pin-and-hole that two or two above cooperations of people could pack straight pin into more, its production efficiency is lower, and is difficult to guarantee the problems such as installation quality of straight pin.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises base plate, be fixed with bed die on the described base plate, the bed die upper end is formed with the circular groove that axis is level, the arc groove bottom is provided with the slotted eye that enters for the straight pin lower end, and the circular groove top is provided with the pressure head that is connected on the press.During assembling, the rotating shaft that will be provided with pin-and-hole earlier is engaged in the arc groove of bed die, and make pin-and-hole up, and then straight pin one end being inserted in the pin-and-hole slightly, the upper end that startup press drive ram acts on straight pin can be press fit into straight pin in the pin-and-hole of rotating shaft.
As preferably, described bed die one side forms a planar structure, the axis normal of described planar structure and arc groove.Wherein, bed die one side look planar structure can make things convenient for and the whole workpiece location that has rotating shaft, though the applying of the planar structure of the side of workpiece and bed die, thus countershaft positions.
As preferably, described bed die upper end is provided with a briquetting, described briquetting lower surface be provided with bed die on arc groove go up arc groove accordingly, described on arc groove on arc groove and the bed die form cylindrical bore jointly; Described briquetting is provided with vertical arc notch corresponding to the slotted eye corresponding position of bed die arc groove bottom.Wherein, briquetting can be pressed in rotating shaft in the arc groove of bed die, prevents the rotating shaft perk, has made things convenient for the operation that press-fits of straight pin; The then convenient location with straight pin of vertical arc notch on the briquetting, thus the axiality of straight pin and pin-and-hole guaranteed, to be convenient to press-fiting of straight pin, guaranteed the installation quality of straight pin.
Therefore, the utlity model has simple in structurely, can enhance productivity, can guarantee the characteristics such as installation quality of straight pin.
Description of drawings
Fig. 1 is that the utility model straight pin fits over the structural representation in the pin-and-hole in advance;
To be the utility model press fit into structural representation in the pin-and-hole with straight pin to Fig. 2.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as depicted in figs. 1 and 2, be fixed with bed die 2 on the base plate 1, bed die 2 upper ends are formed with the circular groove 3 that axis is level, bed die 2 one sides form a planar structure 5, the axis normal of planar structure 5 and arc groove 3, arc groove 3 bottoms are provided with the slotted eye (not expressing among the figure) that enters for the straight pin lower end, bed die 2 upper ends are provided with a briquetting 6, briquetting 6 lower surfaces be provided with bed die 2 on the corresponding arc grooves 7 of going up of arc groove 3, the arc groove 3 common formation cylindrical bore on last arc groove 7 and the bed die 2; Briquetting 6 is provided with vertical arc notch 8 corresponding to the slotted eye corresponding position of arc groove 3 bottoms of bed die 2, and briquetting 6 tops are provided with the pressure head 4 that is connected on the press (not expressing among the figure).
During assembling, as shown in Figure 1, the rotating shaft 9 that will be provided with pin-and-hole earlier is engaged in the arc groove 3 of bed die 2, briquetting then is pressed in the rotating shaft 9, and the pin-and-hole that makes rotating shaft 9 up, then straight pin 10 1 ends are inserted in the pin-and-hole in advance, as shown in Figure 2, starting the upper end that press drive ram 4 acts on straight pin then can be press fit into straight pin in the pin-and-hole of rotating shaft.
Claims (3)
1, a kind of pressure straight pin device, comprise base plate, it is characterized in that being fixed with bed die on the described base plate that the bed die upper end is formed with the circular groove that axis is level, the arc groove bottom is provided with the slotted eye that enters for the straight pin lower end, and the circular groove top is provided with the pressure head that is connected on the press.
