Abstract

The utility model discloses a pin pressing tool of an input shaft, which comprises an upper template, a fixture body and a base plate, wherein both the upper template and the fixture body are fixed on the base plate; the upper template is arranged above the fixture body and is provided with a pin positioning hole; the fixture body is provided with a positioning structure for an input shaft and a torsion bar; and when the input shaft and the torsion bar are fixed on the fixture body through the positioning structure on the fixture body, the axis of the pin positioning hole on the upper template and the axis of the pin positioning hole on the input shaft are arranged on the same straight line. The input shaft and the pin can be positioned accurately, the accuracy of the pressed angle and the position of the pin during the pin pressing process can be improved, the positioning accuracy is high, and pressure tolerance phenomenon caused by inaccurate pressing angle does not occur, so that the reject ratio of products can be reduced, and the cost is saved. Correct pin pressing position reduces the fractured pressure head phenomenon, ensures the safety of operating workers, and reduces accidents.

Description

A kind of power shaft pad frock

Technical field

The utility model relates to the frock of using in a kind of guiding valve production, particularly a kind of power shaft pad frock.

Background technology

In the guiding valve production technology; The technology that is connected of the power shaft of guiding valve and torsion bar is to adopt earlier torsion bar to be inserted power shaft; Desired location on power shaft bores a through hole radially through torsion bar then, and this through hole is the pin fixing hole, then power shaft and torsion bar is placed on the forcing press; Forcing press is pressed into a pin in the pin fixing hole, and power shaft and torsion bar are linked into an integrated entity.This pad process is very strict with angle that is pressed into and status requirement to the pressure of pin.

1, because the workbench of forcing press is a slab construction, do not have the frock clamping, power shaft and pin lean on artificial location.

Be easy to generate deviation when 2, being pressed into, can't be pressed into the tram.

3, produce the deviation continued and be pressed into, mistake be pressed into the fracture that the position can cause pressure head, the pressure head of fracture when serious since pressure collapse to around, might hurt the operator.

Summary of the invention

The problem that the utility model will solve is: a kind of power shaft pad frock is provided, makes it can improve the precision that is pressed into angle and is pressed into the position of power shaft pad process pin.

For addressing the above problem; The utility model comprises cope match-plate pattern, clamp body and substrate, and cope match-plate pattern and clamp body all are fixed on the substrate, and cope match-plate pattern is positioned at the top of clamp body; Cope match-plate pattern is provided with the pin locating hole; Clamp body is provided with the location structure of power shaft and torsion bar, and when power shaft and torsion bar were fixed on the clamp body by the location structure on the clamp body, the axis of the axis of the pin locating hole on the cope match-plate pattern and the pin fixing hole on the power shaft was on same straight line.

In order to improve the accurate positioning property of power shaft and pin; Said location structure comprises the detent of locating shaft, spring catch and power shaft and torsion bar, and locating shaft is arranged on the bottom of clamp body, and substrate is provided with locating hole; The locating shaft of clamp body is inserted in the locating hole of substrate; Detent is arranged on the end face of clamp body, and spring catch is arranged in the clamp body, and the lower end and the clamp body of spring catch are fixed; When power shaft and torsion bar are positioned at detent; The upper limit of the stroke of the upper end of spring catch is arranged in the pin fixing hole of power shaft, and the lower limit of the stroke of the upper end of spring catch is positioned at the below of detent, and the axis of the axis of spring catch and pin locating hole is on same straight line.

The utility model beneficial effect: the utility model can accurately be located power shaft and pin; Improved the precision that is pressed into angle and position of pad process pin; Accurate positioning property is high; Can not produce because of being pressed into the inaccurate pressure off-gage phenomenon that causes of angle, thereby reduce the product disqualification rate, practice thrift cost.The phenomenon of pressure head fracture has been reduced in correct pad position, has guaranteed operator's safety, and the minimizing accident takes place.
