Abstract
The utility model relates to a device for measuring the wall thickness of a metal tube, belonging to a measuring tool in the tube casting industry. The device comprises a wear-resistant metal plate and is characterized in that a notch is arranged on one side of the metal plate; the notch consists of a wide notch and a narrow notch; the wide notch and the narrow notch are communicated with each other; and one side of the notch is an arc-shaped side. The device has simple structure and is convenient to use.
Description
Technical field:
The utility model belongs to the survey instrument of cast tube industry, is specifically related to metal tube pipe thickness measurement mechanism.
Background technology:
The centrifugal casting of spraying thermodyn process is produced in the process of cast carbon steel, requires to measure the thickness of cast carbon steel tube wall.At present, adopt vernier caliper to carry out the measurement of cast carbon steel pipe thickness, its measuring method is complicated.The use of vernier caliper need be through after the training, and ability is on duty.
Summary of the invention:
The utility model provides the simple metal tube pipe thickness of a kind of method of operating measurement mechanism.
The utility model comprises the sheet metal that a high-abrasive material is made, and it is characterized in that a limit of sheet metal is provided with breach, and breach is made up of wide breach and narrow breach, and wide breach and narrow breach communicate, one side breach is the arc limit.
When measuring the metal tube pipe thickness, breach of the present utility model is inserted to the metal tube tube wall, can be extend into wide breach and stretch, illustrate that then the metal tube pipe thickness is qualified less than narrow breach as the metal tube tube wall; As not extending into wide breach, should control weight in the production and reduce wall thickness; If can extend into wide breach and can extend into narrow breach again simultaneously, the metal tube pipe thickness is considered as defective.
The utility model is simple in structure, and is easy to use.
Description of drawings:
The front view of Fig. 1 the utility model embodiment.
Fig. 2 is the right view of Fig. 1.
Among the figure, 1, the antifriction metal (AFM) plate, 2, fabrication hole, 3, narrow breach, 4, wide breach, 5, the arc limit.
Embodiment:
Embodiment: Fig. 1, shown in Figure 2, present embodiment comprises a rectangular metal plate 1, a limit that it is characterized in that rectangular metal plate 1 is provided with breach, breach is made up of wide breach 4 and narrow breach 3, wide breach 4 and narrow breach 3 communicate, the width a of wide breach 4 is 4.8mm, and the width b of narrow breach 3 is 4.1mm, and the limit on breach opposite is arc limit 5.Hole 2 is a fabrication hole.
Illustrate: gap width of the present utility model is to make according to metal tube tube wall specification is different.
Gap width is respectively: wide breach is 4.3mm, and narrow breach is 3.6mm;
Wide breach is 4.4mm, and narrow breach is 3.7mm;
Wide breach is 4.8mm, and narrow breach is 4.1mm;
Wide breach is 4.8mm, and narrow breach is 3.8mm;
Wide breach is 5.8mm, and narrow breach is 4.8mm;
Wide breach is 6.4mm, and narrow breach is 5.2mm;
Wide breach is 7.0mm, and narrow breach is 5.8mm;
Wide breach is 4.0mm, and narrow breach is 3.0mm;
Wide breach is 4.5mm, and narrow breach is 3.5mm;
Wide breach is 5.5mm, and narrow breach is 4.0mm;
Wide breach is 6.0mm, and narrow breach is 5.0mm.
