Description
Technical field
The utility model is related to a kind of for the mach Bidirectional self-centering structure of workpiece.
Background technology
In workpiece machining process, often it is related to the part with concentric circles processing, it is general in process
Using table correction concentricity is beaten manually, which needs to take a long time to adjust the concentric of the circle processing of part two, and
Adjustment process human factor is larger, easily produces maloperation；Therefore for some larger in batches and requirement work pieces process higher
Low production efficiency, and Position location accuracy is poor, or even cause that workpiece is mach to be scrapped, improve production cost.
The content of the invention
Technical problem to be solved in the utility model is to provide one kind for the mach Bidirectional self-centering structure of workpiece,
This structure ensures the concentricity with concentric circular Curve machining process, improves machining production efficiency, reduces production cost,
Ensure that the mach quality of workpiece.
In order to solve the above technical problems, the utility model be used for the mach Bidirectional self-centering structure of workpiece include base,
First support base, the second support base, the first chuck, the second chuck, mandrel, column, crossbeam, locating piece, positioning stud and support
Bolt, first support base and the second support base are respectively separated and are vertical at base two ends top surface, first chuck
Located at the first support base side wall, second support base is provided with through hole, and the mandrel is located at the logical of second support base
In hole, second chuck is located at the mandrel front end, and first chuck and the second chuck be arranged concentrically, the column and fixed
Position block gap is located at the column top surface located at base middle part both sides, the crossbeam level, and the positioning stud passes through spiral shell
Line is located at the locating piece top surface, and the carrying bolt is located at the crossbeam, the positioning stud and carrying bolt by screw thread
Position correspond in opposite directions.
Further, first chuck and the second chuck concentricity≤0.05mm.
Further, the through hole of second support base and mandrel gap cooperation≤0.03mm, the deviation from circular from of the mandrel
≤0.01mm。
Further, this structure also includes turning handle, and the handle that turns is located at the top of the carrying bolt.
Because the utility model employs above-mentioned technical proposal, i.e. this knot for the mach Bidirectional self-centering structure of workpiece
First support base and the second support base of structure are respectively separated and are vertical at base two ends top surface, and the first chuck is located at the first support base
Side wall, the second support base is provided with through hole, and in the through hole of the second support base, the second chuck is located at mandrel front end, first to mandrel
Chuck and the second chuck are arranged concentrically, and, located at base middle part both sides, crossbeam level is located at column top surface for column and positioning block gap,
Positioning stud is located at locating piece top surface by screw thread, and carrying bolt is located at crossbeam, positioning stud and carrying bolt by screw thread
Position corresponds in opposite directions.This structure ensures the concentricity with concentric circular Curve machining process, improves machining production efficiency,
Reduce production cost, it is ensured that the mach quality of workpiece.
Brief description of the drawings
The utility model is described in further detail with implementation method below in conjunction with the accompanying drawings：
Fig. 1 is that the utility model is used for the mach Bidirectional self-centering structural representation of workpiece.
Specific embodiment
Embodiment includes base 1, the as shown in figure 1, the utility model is used for the mach Bidirectional self-centering structure of workpiece
One support base 2, the second support base 3, the first chuck 4, the second chuck 5, mandrel 6, column 7, crossbeam 8, locating piece 9, positioning stud
10 and carrying bolt 11, the support base 3 of first support base 2 and second is respectively separated and is vertical at the two ends top surface of the base 1,
First chuck 4 is located at the side wall of first support base 2, and second support base 3 is provided with through hole, and the mandrel 6 is located at institute
State in the through hole of the second support base 3, second chuck 5 is located at the front end of the mandrel 6, the chuck 5 of first chuck 4 and second
It is arranged concentrically, the column 7 and the interval of locating piece 9 are located at the middle part both sides of the base 1, and the level of the crossbeam 8 is located at described vertical
The top surface of post 7, the positioning stud 10 is located at the top surface of the locating piece 9 by screw thread, and the carrying bolt 11 is located at by screw thread
The crossbeam 8, the positioning stud 10 is corresponding in opposite directions with the position of carrying bolt 11.
Further, first chuck 4 and second, 5 concentricities of chuck≤0.05mm.
Further, the through hole of second support base 3 and the gap cooperation of mandrel 6≤0.03mm, the circularity of the mandrel 6 are missed
Difference≤0.01mm.
Further, this structure also includes turning handle 12, and the handle 12 that turns is located at the top of the carrying bolt 11.
Carrying bolt is rotated by turning handle, facilitates the clamping of workpiece, improves the convenience of operation.
In the machining operation with concentric circular Curve, the diameter and part of the visual stomidium of workpiece two of feeling relieved are long
Spend to select the length of size and the chuck support seat of chuck, workpiece is clamped by positioning stud and carrying bolt, by two
Chuck realizes the processing of workpiece concentric circles.This structure effectively saves the adjustment workpiece concentric time, improves production efficiency, and machine
Processing it is reproducible, it is to avoid the error that human factor is produced, reduce that workpiece is mach scraps, saved and be processed into
This.
