Furthermore, a hydraulic rod is arranged on the left side of the reaming block to control the reaming block to move left and right.
The utility model has the advantages that:
1) the radian of the arc-shaped depressions on the first clamping block and the second clamping block is the same as that of the outer side surface of the oil pipe screw blank, and when the oil pipe screw blank is clamped, the arc-shaped depressions on the first clamping block and the second clamping block are tightly attached to the outer side edge of the oil pipe screw blank, so that the oil pipe screw is prevented from shaking in a clamping manner.
2) The right side of the clamping opening is provided with a top plate which is used for propping one end of the tail part of the oil pipe screw blank which does not need to be reamed, so that the oil pipe screw blank is prevented from moving rightwards during reaming.
3) The heating coil is located the left side of pressing from both sides the mouth, and the portion that oil pipe screw blank head needs the reaming is put inside the heating coil, leads to the red with oil pipe screw blank head heating, makes things convenient for reaming work.
4) The left side of the reaming block is provided with a hydraulic rod to control the left and right movement of the reaming block, when reaming is needed, the reaming block moves rightwards, the upper bottom of the reaming block enters from a hole in the middle of the head of the oil pipe screw blank, the reaming block expands the head of the oil pipe screw blank after entering, the reaming block moves leftwards after reaming, and as the moving distance of the reaming block is fixed every time, the specifications of the oil pipe screw blank are also consistent, and the fact that the size of reaming at every time is consistent is ensured.
5) And the reaming is finished, the thickness of the outer wall of the oil pipe screw is unchanged, the service life is not influenced, and no chips are generated.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the utility model relates to a structural schematic of oil pipe screw reaming frock.
Detailed Description
The following examples are presented to enable those skilled in the art to more fully understand the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1, the structural schematic diagram of a variety of oil pipe screw reaming tools comprises a clamping device 1 and a reaming device 3, the clamping device 1 comprises a first clamping block 11, a second clamping block 12 and a top plate 13, the first clamping block 11 and the second clamping block 12 are located at upper and lower positions, the lower end of the first clamping block 11 and the upper end of the second clamping block 12 are provided with arc-shaped recesses, the arc-shaped recesses extend from the leftmost side to the rightmost side on the clamping blocks, the two arc-shaped recesses are consistent and symmetrical in size, the two arc-shaped recesses are the same as the outer side surface radian of an oil pipe screw blank 2, the top plate 13 is vertically placed at the right side of a clamping opening and the plate surface of the top plate is opposite to the clamping opening, the reaming device 3 comprises a heating coil 33 and a reaming block 32, the heating coil 33 is located at the left side of the clamping opening and the middle channel of the heating, the left side of the hole expanding block 32 is fixedly connected with one end of the hydraulic rod 31.
