Abstract
The utility model discloses a combined clamping fixture for turning a screw rod. The combined clamping fixture comprises a clamping jacket and an inner clamping fixture, wherein the clamping jacket is provided with a three-claw type structure; an inner concave circular truncated cone is arranged at a clamping hole in the end part of the clamping jacket; the inner clamping fixture is adaptive to the inner concave circular truncated cone and arranged in the inner concave circular truncated cone; and a stepped tail hole for mounting a screw is formed in the inner clamping fixture. The head part of the screw is fixed through the inner clamping fixture and mounted downwards in the inner concave circular truncated cone, and the screw can be fixed only through using the clamping jacket to clamp the inner clamping fixture, so as to avoid the phenomenon of screw rod swinging caused by unsteady clamping of the head part of the screw, guarantee the processing precisions and increase the product qualification rate.
Description
Technical field
The utility model relates to anchor clamps, more particularly, relates to a kind of screw rod turning built-up jig.
Background technology
For screw with multi-section type screw, in process, adopt plain clamp directly screw head to be clamped, carry out turning.But because its bar minister degree is long, head thickness is limited, therefore in actual process, because head clamps instability, is easy to cause the screw rod swing, thereby has influence on machining accuracy.
The utility model content
To the above-mentioned shortcoming that exists in the prior art, the purpose of the utility model provides a kind of screw rod turning built-up jig, can prevent that screw rod from swinging man-hour adding, and guarantees machining accuracy.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
This screw rod turning built-up jig comprises chuck and interior anchor clamps, and chuck is the three-pawl type structure, and its folder hole place, end is provided with the indent round platform, and interior anchor clamps and indent round platform are suitable, and are located in the indent round platform, are provided with the step uropore that is used to install screw in the interior anchor clamps.
Anchor clamps are split-type structural in described, be made up of several aliquots, and the medial extremity diameter of its step uropore and screw head diameter are suitable, and the diameter that outboard end diameter and screw terminal are got out of a predicament or an embarrassing situation is suitable.
In technique scheme; The screw rod turning built-up jig of the utility model comprises chuck and interior anchor clamps; Chuck is the three-pawl type structure, and its folder hole place, end is provided with the indent round platform, and interior anchor clamps and indent round platform are suitable; And be located in the indent round platform, be provided with the step uropore that is used to install screw in the interior anchor clamps.Screw is through interior clamps screw head, and is installed on downwards in the indent round platform, and anchor clamps get final product fixed screw in clamping through chuck, thereby avoided screw head to clamp unstable and cause the screw rod swing, guaranteed machining accuracy, improved the qualification rate of product.

Fig. 2 is the axial view of the chuck end face of the utility model;
Fig. 3 is the cutaway view of the interior anchor clamps of the utility model;
Fig. 4 is the axial view of the interior anchor clamps end face of the utility model;
Fig. 5 is the user mode sketch map of the built-up jig of the utility model.
The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.
See also Fig. 1～shown in Figure 5; The screw rod turning built-up jig screw rod turning built-up jig of the utility model comprises chuck 1 and interior anchor clamps 3; Chuck 1 is the three-pawl type structure, and its folder hole place, end is provided with indent round platform 2, and interior anchor clamps 3 are suitable with indent round platform 2; And be located in the indent round platform 2, be provided with the step uropore 4 that is used to install screw in the interior anchor clamps 3.And anchor clamps 3 be split-type structural in described, constitute (among Fig. 4 be four aliquots formations) by several aliquots, and the medial extremity diameter of its step uropore 4 and screw 5 head diameters are suitable, and the diameter that outboard end diameter and screw terminal are got out of a predicament or an embarrassing situation is suitable.
During use; Screw 5 is filled in from the step uropore 4 of interior anchor clamps 3; Oppositely fill in the indent round platform 2 of chuck 1 then together; Close up internal anchor clamps 3 through three-jaw and lock, close up and screw 5 heads and the screw terminal part of getting out of a predicament or an embarrassing situation is fixedly clamped, can carry out turning to the bar portion of screw 5 and process and interior anchor clamps 3 are simultaneously stressed.Increase owing to so clamp the lifting surface area of back screw 5, clamps more stablely, swing, guaranteed machining accuracy, improved the qualification rate of product thereby can avoid taking place in the turning process screw rod.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
