Description

Tube groove angle measurement unit
Technical field
The present invention relates to a kind of tube groove angle measurement units.
Background technique
Nowadays, as global scientific level continues to develop and the increasingly raising of commercial production levels, people start to life Quality requirement is higher and higher.Under normal circumstances, tube groove angle quality influences very big, groove angle to the quality on production product Spending size influences the deposition rate of weld seam, to influence the quality of weldment and the service life of product.
Nowadays, welding production mainly uses manual measurement tube groove angle, not only time-consuming, laborious, measurement accuracy Poor, measurement is got up more difficult for massproduced part, and tube groove angle measurement of today has certain lack Point.
Summary of the invention
The purpose of the present invention is to provide a kind of tube groove angle measurement unit, solve tube groove measurement efficiency it is low and Production efficiency and reading accuracy in batch production process can be improved in the big problem of data read error.
The technical solution of the invention is as follows:
A kind of tube groove angle measurement unit, it is characterized in that: including left and right two range units；The range unit Including shell, the built-in probe sealing ring with cage connection of shell, probe sealing ring is sleeved on probe, probe by conducting wire with Ultrasonic detector connection, the upper end of probe are stretched outside outside shell, and interior of shell is equipped with spring, and the spring upper end is fixed with shell Connection, lower spring end are fixedly connected with the piston, and the piston upper end is equipped with screw rod, and the screw rod upper end is equipped with nut, the bullet Spring can be by up and down adjustment nut come set pressure；Piston inner ring is equipped with piston inner seal ring, and piston outer ring is equipped with close outside piston Seal, piston left end are equipped with water inlet pipe, and water inlet pipe upper end is equipped with water inlet plug, and piston right end is equipped with escape pipe, the outlet Pipe upper end is equipped with venthole plug, and shell lower end is equipped with elongate rod, and the elongate rod end is equipped with wedge angle wheel；Probe upper end is equipped with Screw hole, probe are connected by the rack shell of the short screw and running gear that are arranged in screw hole, rack shell and running gear Walking dolly be fixedly connected.
The running gear includes walking dolly, and walking dolly is connect with rack shell.
The lower end of the rack shell is equipped with bracket.
Application method: by water inlet pipe to inside range unit plus water, air is drained by escape pipe in range unit, when When range unit inner filling water, water inlet plug and venthole plug are stoppered, by nut adjustment to the top, in this way completion pair The set pressure of spring；
Left and right two range units are placed on right above the pipeline of bevel angle to be measured, by move to the left and to the right come The position on pipeline is adjusted, is in close contact two wedge angle wheels of left and right two range units and tube groove, then starting is visited Head, while running gear at the uniform velocity moves, the data finally obtained obtain pipe by wire transmission to ultrasonic detector, through processing The image of road bevel angle consecutive variations.
Tube groove angle approximate calculation uses formula (1):
θ= arctan[H0/ (h2- h1)] formula (1)
In formula (1), θ is tube groove angle, H0It is for two elongate rod constant spacings of left and right two range units Know value, h1For the instantaneous value of interface distance under the probe and shell of left range unit, h2The probe and shell lower bound of right range unit Identity distance from instantaneous value.
Present invention employs ultrasonic distance measurement principle, the measurement accuracy in production process is improved.It can be filled by measuring angle It sets to be measured to bevel angle, display pipes on a display screen can be handled by the data of probe wire transmission measurement The image of the consecutive variations of bevel angle.
