Embodiment 1

[0070] like figure 1 , figure 2 As shown in the figure, the device for measuring the diameter of a round tube product by the cross method includes a workbench 1, a base 2, two measuring components, two tolerance probe components, a positioning column 7, and a positioning component 8; the two measuring components have the same structure and are located in The horizontal position and the vertical position, the measuring component located in the horizontal position is the horizontal measuring component 3, the measuring component located in the vertical position is the vertical measuring component 4, the two are vertically distributed to each other, the horizontal measuring component is used to measure the inner diameter in the horizontal direction, and the vertical measuring component 4 For measuring the inner diameter in the vertical direction, the two tolerance probe assemblies are the horizontal tolerance probe assembly 5 and the vertical tolerance probe assembly 6. The horiz...

Embodiment 2

[0086] This embodiment provides a method for measuring the inner diameter of a round tube product by the cross method in the above-mentioned first embodiment, which includes the following steps:

[0087] Step S1: debug the device;

[0088] Specifically, if the inner diameter of a product is φ81±0.3mm, the upper limit size is φ81.3mm, and the lower limit size is φ80.7mm. Before debugging the equipment, process the lower and upper tolerance gauges with inner diameters of φ80.70mm and φ81.3mm.

[0089] Put the 80.70mm inner diameter lower tolerance check tool into the positioning column 7, the positioning cylinder 81 moves, and drives the positioning slide rod 82 to move away from the center of the circle, until the positioning slider 821 contacts the inner wall of the inner diameter lower tolerance check tool, stops the movement, and the positioning slide The block 821 and the limiting rib 71 form three support points to clamp the lower tolerance check tool; the horizontal meas...

Embodiment 3

[0108] This embodiment adopts the above-mentioned method of measuring the outer diameter of the round tube product by the cross method. When the above-mentioned device is used to measure the outer diameter, the difference from the device in the first embodiment is that the horizontal tolerance probe assembly 5 is located at the swing rod 33 of the horizontal measurement assembly 3. On the right side, the upper tolerance probe 53 is located below the upper tolerance probe 53, and the protruding length of the upper tolerance probe 53 is greater than the length of the upper tolerance probe 53; the vertical tolerance probe assembly 6 is located on the swing rod of the horizontal measurement assembly 3 33 on the upper side.

[0109] The steps of the method for measuring the outer diameter of the round tube product by the cross method are as follows with reference to Embodiment 2:

[0110] Step S1: debug the device;

[0111] Specifically, if the outer diameter of a product is φ100±...

Abstract

The invention discloses a device for measuring the diameter of a circular tube product through a cross method. The device comprises a workbench, a base, a plurality of measuring assemblies, a plurality of tolerance probe assemblies, a positioning column and a positioning assembly. The positioning column is connected with the base. The positioning assembly comprises a positioning sliding rod capable of moving in the radial direction. The at least two measuring assemblies are arranged perpendicular to each other, and the measuring assemblies are connected with the workbench; the measuring assembly comprises a measuring sliding rod capable of moving in the radial direction and a swing rod, the measuring sliding rod comprises at least two measuring blocks, the middle of the swing rod is hinged to the base, one end of the swing rod is movably connected with the measuring sliding rod, and the other end of the swing rod extends to the side face of the tolerance probe assembly; the tolerance probe assembly comprises an upper tolerance probe and a lower tolerance probe which are arranged in parallel in a horizontal plane. The invention further discloses a method for measuring the diameter of the round pipe product through the cross method. The automatic production line has the beneficial effects that automatic continuous production is achieved, products are taken and placed through the robot, qualified parts and unqualified parts are separated, and efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of product size measurement, in particular to a device and method for measuring the size of a round pipe product. Background technique [0002] Existing round pipe products, such as exhaust tail pipes, etc., are tested to confirm whether the products are qualified, usually key dimensions (inner diameter, outer diameter, height) are measured. After measuring and comparing the measured data with the target value, qualified products and unqualified products are distinguished. Manual reading has the problems of large errors and slow efficiency. [0003] Chinese patent document CN212363051U discloses a pipe fitting inner diameter roundness tolerance tester, including a threaded barrel, two threaded rods are threadedly connected to the inner side wall of the threaded barrel, and an installation box is fixedly connected to the outer side wall of the threaded barrel. The outer side wall of the box penetrates and is...
