Problems solved by technology

The current inspection tools are roughly divided into two categories, one is for the error measurement of a specific workpiece, and it is not applicable after replacing another workpiece, and the scope of use of the inspection tool is very narrow; the other is for the measurement of error categories, respectively through Special measurement tools are completed, because the error measurement standards are not uniform enough, which affects the accuracy of the measurement results; in addition, in riveting welders and ordinary fitters, circle marking, circumferential index marking, concentric circle marking, arc measurement, vertical When drawing lines and parallel lines, etc., it is also hoped that it can be completed with the help of a versatile tool

Embodiment 1

[0025] see figure 1 , image 3 , a kind of multi-functional inspection tool, comprises reference support 1, and the center of described reference support is provided with support guide post 2 vertically, and described support guide post is provided with height scale 3; On described support guide post The lifting bracket 4 is set, and an axial locking mechanism is arranged on the lifting bracket; a rocker guide rod 5 is arranged above the lifting bracket, and one end of the rocker guide rod is hinged with the guide column of the support through a sliding sleeve 6, so that The rocker arm guide rod is provided with a radius scale 7; the rocker arm guide rod is provided with a slide seat 8, and the slide seat is provided with a horizontal positioning hole 9 and a vertical positioning hole 10, and the horizontal positioning hole and the A set screw 11 is arranged on one side of the vertical positioning hole, and a dial indicator 12 is installed on the horizontal positioning hole o...

Embodiment 2

[0034] This embodiment is an improvement made on the basis of Embodiment 1. For the same parts as in Embodiment 1, please refer to the content disclosed in Embodiment 1 for understanding, and no repeated description will be made here.

[0035] see Figure 12 , Figure 13 , in this embodiment, the sliding sleeve 6 of the rocker arm guide rod 5 is provided with an anti-rotation groove 18, and the stop long ruler 19 is fixed on the reference support 1, and the stop long ruler is stuck on the anti-rotation In the turn slot. The bottom of the stop ruler is fixed on the reference support 1 by screws 20, and the stop ruler cooperates with the anti-rotation groove to realize the circumferential fixation of the rocker guide rod, and the slide seat can only move along the rocker arm. The guide rod moves in a straight line. By keeping the rocker arm guide rod parallel to the axis of the workpiece to be measured, the straightness error of the workpiece to be measured can be detected. ...

Embodiment 3

[0039]This embodiment is an improvement made on the basis of Embodiment 1. For the same parts as in Embodiment 1, please refer to the content disclosed in Embodiment 1 for understanding, and no repeated description will be made here.

[0040] see Figure 5 , in the present embodiment, the bottom of the slide seat 8 is provided with a threaded hole, the threaded hole is fixed with a marking cone 22, the tapered rod of the marking cone is provided with an external thread, and the tapered rod of the marking cone is connected to the Threaded hole threaded connection. Also be equipped with backstop nut 23 on the tapered rod of marking cone, the end face of backstop nut is pressed against on the described slide seat. A set screw 24 is arranged on the sliding seat. The set screw can realize the positioning of the sliding seat on the rocker arm guide rod 5 .

[0041] Before drawing concentric circles, first determine the center of the reference circle, draw two straight lines throu...

Abstract

The invention relates to a multifunctional testing fixture. The multifunctional testing fixture comprises a reference bearer. A bearer guide column is vertically arranged at the center of the reference bearer and is provided with a height scale; the bearer guide column is sleeved by an elevating holder which is provided with an axial locking mechanism; a rocking arm guide rod is arranged above the elevating holder, one end of the rocking arm guide rod is hinged to the bearer guide column through a sliding sleeve, and the rocking arm guide rod is provided with a radius scale; and the rocking arm guide rod is provided with a sliding seat, the sliding seat is provided with a horizontal positioning hole and a vertical positioning hole, the side of the horizontal positioning hole and the veridical positioning hole is provided with a fastening screw, and the horizontal positioning hole or the vertical positioning hole of the sliding seat is provided with a dial gauge. The multifunctional testing fixture can simultaneously realize multiple error detection of workpieces, and is simple in structure, simple to operate and high in practicality.

Description

technical field [0001] The invention relates to the field of measuring equipment, in particular to a multifunctional inspection tool. Background technique [0002] Some parts on construction machinery have errors in size after processing, and the actual shape or mutual position of the points, lines, and surfaces that constitute the geometric features of the part are inevitably different from the shape and mutual position specified by the ideal geometry. The difference is the shape error, and the difference in mutual position is the position error, collectively referred to as the shape tolerance. The current inspection tools are roughly divided into two categories, one is for the error measurement of a specific workpiece, and it is not applicable after replacing another workpiece, and the scope of use of the inspection tool is very narrow; the other is for the measurement of error categories, respectively through Special measurement tools are completed, because the measureme...
