Embodiment Construction

[0012] Such as figure 1 As shown, the cylindricity detection device of the spiral bond joint of the present invention includes a base on which a workpiece frame 1 is fixed, and the upper surface of the workpiece frame 1 is provided with a V-shaped groove 2 along the length direction. The base is also provided with a chute, a supporting plate 3 is installed in the chute, a table frame 4 is arranged on the supporting plate 3, a vertical pole 5 is fixed on the table frame 4, and a horizontal pole is arranged on the vertical pole 5 6. A dial gauge 7 is provided on the transverse strut 6, the head of the dial gauge 7 faces downward, and the head is located above the workpiece holder 1. A fixing plate 8 is also provided between the workpiece holder 1 and the pallet 3 . A steel ball 9 is arranged on the fixed plate 8 opposite to the workpiece holder 1 for rotation. The steel ball 9 is set to contact the workpiece through the steel ball 9 to prevent the end of the workpiece from dir...

Abstract

The invention provides a cylindricity detection device for a helical twisted tape joint. The cylindricity detection device comprises a base, wherein a workpiece bracket is fixed on the base, a V-shaped groove is formed in the upper surface of the workpiece bracket in the length direction, a to-be-detected workpiece is placed in the V-shaped groove, and the workpiece is clamped and placed on the workpiece bracket under gravity for detection. A header of a dial indicator is contacted with the workpiece through adjustment of the height of a horizontal support rod, the workpiece is rotated slowly to enable the workpiece to rotate in the V-shaped groove, and the cylindricity of the workpiece in one perimeter can be judged through reading on the dial indicator. Then a support plate is moved, so that the support plate can move in a chute and get close to or far from the workpiece, the contact position of the workpiece and the header is changed, then the workpiece is rotated, and the cylindricity in next perimeter is detected. The cylindricity of the helical twisted tape joint is detected by adopting a simple structure, the detection data are accurate, and a product meets processing and using requirements.

Description

technical field [0001] The invention relates to a mechanical measurement and detection device, in particular to a cylindricity detection device for a spiral bond joint. Background technique [0002] The spiral tie is a simple swirl device in the pipe, the sealing gasket. It is twisted from a thin sheet with a width approximately equal to the inner diameter of the pipe and a thickness of approximately 1 to 2 mm. On this basis, the experiments focus on the special working conditions of the link in different application occasions, and propose different link optimization structures respectively. The width and pitch of the spiral link were optimized and compared, and it was found that the wide link has a large dynamic moment and has strong anti-scale and scale-removing capabilities. The vertical water cooler with a small flow rate should use a link with a large width and a small pitch, and a horizontal link with a large flow rate. Medium-width, medium-pitch ties should be used ...
