Abstract
The invention discloses a clamp used for coupling external round of vehicles and the application of the clamp. The clamp comprises a lathe three-claw chuck and a movable claw which is arranged on thechuck; the movable claw is provided with three installation troughs; three clamp claws are installed by the installation trough; the external side of the clamp claw is provided with a coupling blank to be processed by a tightening screw; the internal side of the tail end of the clamp claw is provided with a standard lathe tail seat movable tip which braceds against the coupling blank. The application method is that the coupling blank is arranged in three clamp claws; the radial jumping of the external round of the coupling blank is detected; when the radial jumping is within the allowable range, the normal turning process procedure is directly carried out; when the radial jumping is oversize, a front internal hexagonal tightening screw and a rear internal hexagonal tightening screw on theclamp claws are adjusted so as to adjust the radial jumping in the allowable range and then carry out the normal turning process procedure. Without increasing the normal processing allowance, the clamp can process the coupling blanks with the normal detects of ellipse and non-uniform wall thickness, etc. and effectively ensure the final processing quality of the products.
Description
Technical field
The present invention relates to a kind of oil and gas industry casing coupling cylindrical processing technique field instrument and application thereof, automobile-used anchor clamps of particularly a kind of casing coupling cylindrical and application thereof.
Background technology
Require the casing coupling of production according to the API 5CT of American Petroleum Institute (API) " sleeve pipe and oil pipe standard ", its outside diameter size and surface quality all have the requirement of comparison strictness, and general casing coupling processing factory adopts the method for machining to satisfy box cupling excircle dimension precision and surface quality requirement.Because the casing coupling diameter is bigger, wall thickness is thinner, and relative length is longer, so general casing coupling processing factory all uses special anchor clamps.
It is multifarious that existing casing coupling cylindrical is processed special anchor clamps, but but neither one is more satisfactory.Its reason is as follows:
1, must be seamless according to API 5CT regulation casing coupling blank.Because all there are normal defects such as ellipse, wall thickness be irregular in the limitation of domestic rolling and Technology for Heating Processing, all casing coupling blanks.
If 2 adopt conventional processing technology and anchor clamps, consider the ellipse and the wall unevenness defective of box cupling blank simultaneously, the machine-finish allowance that certainly will strengthen reservation is to satisfy the final products requirement.So promptly increased the casing coupling product cost of raw material, increased machine-finish allowance simultaneously and also increased processing cost, in energy-saving and cost-reducing unfavorable.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art, automobile-used anchor clamps of a kind of casing coupling cylindrical and application thereof are provided, it can process and effectively guarantee the final crudy of product to the box cupling blank that has normal defects such as ellipse, wall unevenness under the prerequisite that does not increase conventional allowance.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
The automobile-used anchor clamps of a kind of casing coupling cylindrical of the present invention, comprise the lathe scroll chuck and be installed in movable claw on the chuck, described movable claw is provided with three mounting grooves, by mounting groove three gripper jaws are installed, the described gripper jaws outside is equipped with box cupling blank to be processed by trip bolt, gripper jaws tail end installed inside has standard tail stock rolling center, described standard tail stock rolling center stretching box cupling blank.
Be provided with forward and backward interior hexagonal holding screw on each gripper jaws respectively.
The present invention discloses the application of the automobile-used anchor clamps of a kind of described casing coupling cylindrical, box cupling blank three gripper jaws of packing into routinely detect the cylindrical circular runout of box cupling blank, when circular runout during in allowed band, directly enter normal turning procedure; When circular runout is overproof,, adjusts circular runout and to allowed band, enter normal turning procedure again by adjusting hexagonal holding screw in the front and back on the gripper jaws.
The present invention adopts three gripper jaws and passes through standard tail stock rolling center stretching box cupling blank, to guarantee the steady rigidity of box cupling turning process; The circular runout of totally six holding screw adjustment box cupling blank cylindricals before and after adopting is to guarantee the cylindrical crudy of product.
The beneficial effect of technical scheme provided by the invention is:
The automobile-used anchor clamps of casing coupling cylindrical of the present invention can satisfy among the API 5CT " sleeve pipe and oil pipe standard " the cylindrical crudy to the casing coupling blank, can additionally not increase machine-finish allowance simultaneously, effectively reduce material cost and machining cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation after the automobile-used anchor clamps of casing coupling cylindrical of the present invention have been installed box cupling blank to be processed.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the automobile-used anchor clamps of a kind of casing coupling cylindrical of the present invention, comprise the standard lathe chuck and be installed in three movable claws 7 on the chuck, the movable claw of described standard lathe chuck is provided with three mounting grooves, by mounting groove three gripper jaws 2 are installed, the described gripper jaws outside is equipped with box cupling blank 3 to be processed by trip bolt 4, and gripper jaws tail end installed inside has standard tail stock rolling center 1, described standard tail stock rolling center stretching box cupling blank.
Be provided with forward and backward interior hexagonal holding screw 5,6 on each gripper jaws respectively.
Being applied as of the described automobile-used anchor clamps of casing coupling cylindrical: box cupling blank three gripper jaws of packing into routinely, detect the cylindrical circular runout of box cupling blank, when circular runout during, directly enter normal turning procedure in allowed band; When circular runout is overproof,, adjusts circular runout and to allowed band, enter normal turning procedure again by adjusting hexagonal holding screw in the front and back on the gripper jaws.
The present invention adopts three gripper jaws and passes through standard tail stock rolling center stretching box cupling blank, to guarantee the steady rigidity of box cupling turning process; The circular runout of totally six holding screw adjustment box cupling blank cylindricals before and after adopting is to guarantee the cylindrical crudy of product.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
