beneficial effect
The utility model relates to a kind of for the precision machined clamp structure of auto pump lid, simple in structure, can make turning and fraising complete simultaneously and ensure the stable of axiality, has improved significantly operating efficiency.
Brief description of the drawings
Fig. 1 is that master of the present utility model looks sectional structure chart;
Fig. 2 is part processing structure figure of the present utility model;
Fig. 3 is plan structure figure of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As Figure 1-3, embodiment of the present utility model relates to a kind of for the precision machined clamp structure of auto pump lid, comprise brake pad 2, drill chuck connecting portion 3 and fixture 5, described fixture 5 is disc, its circle centre position is vertically through reamer 10 is installed, the outside of described fixture 5 is connected with float plate 7 levels by bearing 6, described float plate 7 one side lower ends are connected with fuselage 11 by vertical mounting spring 8, opposite side is connected with support 15 slips that are arranged on fuselage 11, described support 15 inner horizontal are provided with lathe tool 9, top and its lower end that described drill chuck connecting portion 3 is arranged in fixture 5 are connected with brake pad 2, both center lines overlap with the center line of reamer 10.
The upper end of described reamer 10 contacts through embedding to be arranged on the drill bushing 4 at fixture 5 centers and to protrude upward with clamping the centre bore that is arranged in the part 1 brake pad 2 and fixture 5, and the other end is fixed in fuselage 11.
Described lathe tool 9 is through support 15, on the path that the outer rim that its edge of a knife end is arranged in part 1 moves down.
Described spring 8 is socketed in vertically through the outside of the cylinder 12 of float plate 7 and float plate 7 and fuselage 11.
Described cylinder 12 upper ends are furnished with round barrel cover 13, and the upper surface of described float plate 7 is provided with the pad 14 being connected with cylinder 12.
Described bearing 6 has 2, is arranged in the position that the upper and lower end face of float plate 7 contacts with fixture 5.
The bottom centre of described fixture 5 is furnished with cone-shaped groove.
Embodiment 1
Part 1 is placed on fixture 5, drill chuck connecting portion 3 start rotation and down straightening to fastening part 1, the frictional force that the brake pad 2 being connected with by drill chuck connecting portion 3 lower ends produces drives part 1 on horizontal plane, to rotate together with fixture 5, drill chuck connecting portion 3 continues toward pressing down, and part 1 rotates descending along with pressing down of drill chuck connecting portion 3 together with fixture 5.
