Welding positioning fixture for banjo and anti-rotating pin

Abstract

The invention relates to a welding positioning fixture for a banjo and anti-rotating pin. The fixture comprises a base, wherein an anti-rotating pin fixing base and a spring bolt fixing base are arranged at the upper part of the left side of the base; a fixed bracket is fixedly arranged at the upper part of the right side of the base by virtue of a bolt; a trapezoid port spring positioning bolt and a hole spring positioning bolt horizontally penetrate through the anti-rotating pin fixing base and the spring bolt fixing base; the left side of the fixed bracket is provided with a guide sleeve; a guide column passes through the guide sleeve; the right side of the fixed bracket is connected with a wrench by virtue of a hinge; the wrench is connected with the guide column by virtue of a push-and-pull block. The welding positioning fixture has the beneficial effects that a banjo is automatically positioned by virtue of a chamfer on the right side of the spring positioning bolt and a trapezoidal groove on the right side of the trapezoid port spring positioning bolt, and the welding position of the anti-rotating pin is determined by virtue of a profile groove in the top of the anti-rotating pin positioning base, so that the welding accuracy of the banjo and anti-rotating pin is ensured, and the labor efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a banjo anti-rotation pin welding positioning tool. Background technique [0002] There are many ways to connect the steering oil pipe and steering pump of automobiles with banjo connection. When the banjo is installed or the car is running, there is a risk that the banjo will rotate on the steering pump. Therefore, an anti-rotation pin with a fixed installation angle needs to be designed on the banjo. Such as image 3 As shown, the processed banjo must ensure the coaxiality of the free end of the anti-rotation pin 81 and the axis of the end face hollow 82, and ensure that the welding position of the anti-rotation pin 81 forms a fixed angle with the cylindrical section 83. The current banjo anti-rotation pin Welding is affected by the machining accuracy of the banjo body (coaxiality, runout, machining tolerance, etc.), so it is impossible to effectively guarantee th...

like image 3 As shown, the processed banjo must ensure the coaxiality of the free end of the anti-rotation pin 81 and the axis of the end face hollow 82, and ensure that the welding position of the anti-rotation pin 81 forms a fixed angle with the cylindrical section 83. The current banjo anti-rotation pin Welding is affected by the machining accuracy of the banjo body (coaxiality, runout, machining tolerance, etc.), so it is impossible to effectively guarantee the consistency of the welding angle when welding the anti-rotation pin
