Abstract

An annular flaw-processing auxiliary device for inner surfaces of tubes comprises a mounting bracket, a manual feed mechanism and a trolley mechanism. The auxiliary device has the advantages that a flaw processing machine is mounted and used on the trolley mechanism, an inner milling mechanism of the flaw-processing machine is driven to realize profiling motion along the inner surfaces of the tubes when the trolley mechanism is in circumferential motion on the inner surfaces of the tubes, thereby ensuring uniform processing depth of blades and meeting requirements of restoring grooved defect of the flaw-processing machine.

Description

The internal surface of pipe hoop is carved and is hindered servicing unit

Technical field:

The utility model relates to the servicing unit of a kind of etching machine processing internal surface of pipe hoop flute profile defective of using at the construction field (site) in the Non-Destructive Testing.

Background technology:

The flute profile defective of the etching machine processing internal surface of pipe that existing Non-Destructive Testing is used at the construction field (site) mainly is a principle of utilizing mechanical Milling Process, axially processes the flute profile defective at tubing.The existing etching machine that uses at the construction field (site) can not be processed for the hoop flute profile defective of tubing.Along with the development of industrial technology, more and more higher to the quality requirements of tubing, constantly require to detect the inside surface hoop defective of tubing in some fields, the inside surface circumferential groove that must process tubing normally provides condition for Non-Destructive Testing.

The utility model content:

The purpose of this utility model is to provide a kind of running gear of etching machine processing internal surface of pipe hoop flute profile defective, thereby utilizes original etching machine to process internal surface of pipe hoop flute profile defective easily.

Technical solutions of the utility model are: the internal surface of pipe hoop is carved and to be hindered servicing unit and comprise mounting bracket, hand feeding mechanism and trolley body, and described mounting bracket comprises spiral expansion link with positive antispin, be installed in the arc back up pad at spiral expansion link two ends and be fixed on installing plate on the back up pad; Described hand feeding mechanism is fixed on the mounting bracket by installing plate, and described hand feeding mechanism comprises horizontal screw lead, with the screw of horizontal slideway and the shaft seat that can vertically move freely along vertical slots on the screw; Described trolley body comprise dolly, fixedly etching machine connection seat and be fixed on dolly push rod on the trolley body, trolley body and hand feeding mechanism link by axis hole on the dolly push rod and the rotating shaft on the shaft seat on the hand feeding mechanism.

Advantage of the present utility model is to install on the trolley body to utilize and has etching machine now, it is moving that the interior milling mechanism that drives etching machine by trolley body when the circumferential movement of internal surface of pipe is done profiling along internal surface of pipe, guarantee the working depth unanimity of blade, satisfied the requirement of the desired flute profile defect repair of defectoscope.

Description of drawings:

Fig. 1 is the utility model structural representation.

Wherein 1 is that spiral expansion link, 2 is that arc back up pad, 3 is that installing plate, 4 is that horizontal screw lead, 5 is that screw, 6 is that shaft seat, 7 is that dolly, 8 is that dolly push rod, 9 is a tubing to be processed.

Embodiment:

Below in conjunction with drawings and Examples the utility model is further specified.

The utility model when mounted, at first fixedly the holder and the trolley body of etching machine are fixed with etching machine usefulness, and trolley body is placed in the tubing that will process hoop flute profile defective, the direction of dolly is along tubing hoop travel direction, adjust etching machine in mill milling cutter on the kinematic train, make itself and tubing inner arc tangent; Secondly mixing up fixed support spiral length of telescopic bar in advance makes two arc plate outer end length less than pipe internal diameter, install hand feeding mechanism with screw, hand feeding mechanism and fixed support are put into the positive left-hand thread screw of adjusting in the tubing on the screw rod to be made on the fixing internal surface of pipe of erecting frame, note center line and the level of the center line of screw rod by pipe internal diameter, connect the push rod of shaft seat and trolley body carefully with the little axle on the shaft seat then. at this moment adjust the horizontal screw lead on the hand feeding mechanism, trolley body just can move along the internal surface of pipe arc, adjust on the etching machine in milling system milling cutter up and down and the front and back feeding just can adjust groove depth that milling cutter is processed.

The utility model is when work, move forwards or backwards by the horizontal screw lead promotion trolley body of adjusting in the hand feed system, when trolley body moves along internal surface of pipe, trolley body produces up and down and also produces the displacement of the lines of front and back the time angular displacement, displacement of the lines is moved up and down by the tangential movement of leading screw and the shaft seat vertical slots of screw on the leading screw and eliminates, angular displacement is eliminated by the rotating shaft on the shaft seat, so just guaranteed trolley body steady along the pipe internal diameter circular motion, because the vertical counter-force that the deadweight of trolley body and etching machine produces when the etching machine milling cutter is worked, trolley body is 20 to 30 millimeters along the distance of pipe internal diameter circular motion, the milling cutter working depth is less than 1 millimeter, during etching machine work, the trolley body horizontal positioned, on the tubing vertical direction and the displacement of the lines that produces downwards much smaller than the air line distance of dolly tangential movement, guaranteed the stable working of trolley body equally.

Claims

1. an internal surface of pipe hoop is carved and is hindered servicing unit, it is characterized in that it comprises mounting bracket, hand feeding mechanism and trolley body, described mounting bracket comprises spiral expansion link with positive antispin, be installed in the arc back up pad at spiral expansion link two ends and be fixed on installing plate on the back up pad; Described hand feeding mechanism is fixed on the mounting bracket by installing plate, and described hand feeding mechanism comprises horizontal screw lead, with the screw of horizontal slideway and the shaft seat that can vertically move freely along vertical slots on the screw; Described trolley body comprise dolly, fixedly etching machine connection seat and be fixed on dolly push rod on the trolley body, trolley body and hand feeding mechanism link by axis hole on the dolly push rod and the rotating shaft on the shaft seat on the hand feeding mechanism.
