Abstract
The utility model discloses a coupling excircle automobile-used clamp which comprises a lathe three-jaw chuck and a movable claw, wherein, the movable claw is arranged on the chuck; the movable claw is provided with three installation troughs; three clamp claws are arranged through the installation troughs; the outer side of each clamp claw is provided with a coupling roughcast to be processed through trip bolts; the inner side of the tail end of each clamp claw is provided with a standard lathe tailstock movable tip; and the standard lathe tailstock movable tip tight supports the coupling roughcast. The coupling excircle automobile-used clamp can process the coupling roughcast having conventional defects of ellipse, unevenness wall thickness, and the like and effectively ensures final processing quality of products under the premise of no-increasing conventional processing allowance.
Description
Technical field
The utility model relates to a kind of oil and gas industry casing coupling cylindrical processing technique field instrument, particularly a kind of jig for machining coupling excircle.
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.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, a kind of jig for machining coupling excircle is 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 utility model adopts following technical scheme:
A kind of jig for machining coupling excircle of the utility model, 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 utility model 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.
Operation principle of the present utility model is: box cupling blank three gripper jaws of packing into routinely, detect the cylindrical circular runout of box cupling blank, and 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 beneficial effect of the technical scheme that the utility model provides is:
The utility model jig for machining coupling excircle 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 reduces material cost and machining cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation after jig for machining coupling excircle described in the utility model has been installed box cupling blank to be processed.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of jig for machining coupling excircle 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.
The utility model 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.
Operation principle of the present utility model is: box cupling blank three gripper jaws of packing into routinely, detect the cylindrical circular runout of box cupling blank, and 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 above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. jig for machining coupling excircle, comprise the lathe scroll chuck and be installed in movable claw on the chuck, it is characterized in that: 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.
