Abstract
The utility model discloses a horizontal lathe screw mandrel protecting device, which comprises two opening-closing nut support plates, the opening-closing nut support plates are respectively fixed at a sliding box, an upper opening-closing nut and a lower opening-closing nut are matched with the opening-closing nut support plate in a sliding way; the upper opening-closing nut is provided with a groove, a screw mandrel protecting plate passes through the groove, both ends of the screw mandrel protecting plate are respectively fixed at the lathe body; the connecting line of the outer end and the inner end of the opening of the upper opening-closing nut and the horizontal line which passes the outer end of the opening form a negative angle, the lower opening-closing nut is matched with the upper opening-closing nut. The horizontal lathe screw mandrel protecting device not only has simple structure but also has low manufacturing cost.
Description
Affiliated technical field
The utility model relates to a kind of horizontal lathe screw mandrel protector.
Background technology
Existing a kind of horizontal lathe screw mandrel protector, it contains two clasp nut gripper shoes, the clasp nut gripper shoe is separately fixed on the slip crate, last clasp nut is slidingly matched with the clasp nut gripper shoe respectively with following clasp nut, on last clasp nut and the following clasp nut cam pin is housed respectively, last clasp nut is provided with groove, and the screw mandrel protective plate passes from groove, and the two ends of screw mandrel protective plate are separately fixed on the lathe bed.Owing on last clasp nut, have groove, because of the outer end and the inner line of the opening of last clasp nut is on the horizontal plane, therefore the intensity that is positioned at the bottom land below part that clasp nut slots reduces greatly, thereby damage easily, has shortened service life greatly.In order to improve intensity and increasing the service life, prior art has adopted and will go up clasp nut and be made into clasp nut body and last clasp nut body, and the method that groove is opened on last clasp nut body solves.But it is complicated that the structure that so not only makes protector becomes, and manufacturing cost is also higher.
The utility model content
The technical problems to be solved in the utility model provides horizontal lathe screw mandrel protector, and it is not only simple in structure, and low cost of manufacture.
The technical scheme that its technical problem that solves the utility model adopts is: it contains two clasp nut gripper shoes, the clasp nut gripper shoe is separately fixed on the slip crate, last clasp nut is slidingly matched with following clasp nut and clasp nut gripper shoe, last clasp nut is provided with groove, the screw mandrel protective plate passes from groove, the two ends of screw mandrel protective plate are separately fixed on the lathe bed, the outer end of the described upward opening of clasp nut and inner line are negative angle with the horizontal line angulation of the outer end of crossing opening, and following clasp nut and last clasp nut match.
The outer end of the described upward opening of clasp nut and inner line are 2 ° to-45 ° with the negative angle that horizontal line became of the outer end of crossing opening.
Because the line of the outer end of the opening of last clasp nut and the inner is a negative angle with the horizontal line angulation of the outer end of crossing opening, following clasp nut and last clasp nut match, therefore it is thicker than the prior art to be positioned at the bottom land below thickness partly that clasp nut slots, thereby has obtained prolongation in intensity, the service life of having improved this part.Because by such improvement, needn't be again clasp nut be made into structure clasp nut body and the clasp nut body as prior art, so not only simple in structure, and manufacturing cost has also obtained reduction.
Description of drawings
Accompanying drawing is the utility model horizontal lathe screw mandrel protector structural representation.
1. clasp nut gripper shoes in the accompanying drawing, 2. protective plate, 3. groove, 4. lathe bed is 5. gone up clasp nut, 6. screw mandrel, 7. outer end, 8. horizontal line 9. descends clasp nut, 10. the inner, 11. lines, 12. cam pins, 13. cam pins, 14. bottom lands below part.
The specific embodiment
In the accompanying drawing, the utility model horizontal lathe screw mandrel protector, it contains two clasp nut gripper shoes 1, and this gripper shoe 1 is separately fixed on the slip crate, and is not shown in the figures.Last clasp nut 5 is slidingly matched with gripper shoe 1 with following clasp nut 9, on last clasp nut 5 and the following clasp nut 9 cam pin 12 and 13 is housed respectively. Cam pin 12 and 13 is positioned at the cam path of the cam on the slip crate, cam rotates when turning handle, at this moment cam driven is positioned at the cam pin 12 and 13 of cam path, make they drive respectively clasp nut 5 and following clasp nut 9 on clasp nut gripper shoe 1 in opposite directions or opposite moving, thereby realize going up opening or closing of clasp nut 5 and following clasp nut 9.Last clasp nut 5 is provided with groove 3, and the protective plate 2 of screw mandrel 6 passes from groove 3, and the two ends of the protective plate 2 of screw mandrel 6 are separately fixed on the lathe bed 4.The outer end 7 of the opening of last clasp nut 5 and inner 10 line 11 are negative angle with horizontal line 8 angulations of the outer end 7 of crossing opening, and following clasp nut 9 matches with last clasp nut 5.In the practice, consider that the negative angle that horizontal line became of the line of the outer end 7 of the opening of last clasp nut 5 and the inner 10 and the outer end 7 of mistake opening can be between-2 ° to-45 ° according to combined factors such as the material of last clasp nut 5 and following clasp nut 9 and chi sizes.Because the outer end 7 of the upward opening of clasp nut 5 of the present utility model and inner 10 line 11 are negative angle with horizontal line 8 angulations of the outer end 7 of crossing opening, following clasp nut 9 matches with last clasp nut 5, therefore it is thicker than the prior art to be positioned at below the bottom land of clasp nut 5 thickness of part 14, thereby improved the intensity of bottom land below part 14, obtained prolongation service life.Compared with prior art, needn't again clasp nut be made into clasp nut body and clasp nut body, therefore not only simple in structure, and easy to manufacture, production cost is low.
Claims (2)
1. horizontal lathe screw mandrel protector, it contains two clasp nut gripper shoes, the clasp nut gripper shoe is separately fixed on the slip crate, last clasp nut is slidingly matched with following clasp nut and clasp nut gripper shoe, last clasp nut is provided with groove, the screw mandrel protective plate passes from groove, the two ends of screw mandrel protective plate are separately fixed on the lathe bed, it is characterized in that: the outer end of the described upward opening of clasp nut and inner line are negative angle with the horizontal line angulation of the outer end of crossing opening, and following clasp nut and last clasp nut match.
2. a kind of horizontal lathe screw mandrel protector according to claim 1 is characterized in that: described outer end of going up the opening of clasp nut is-2 ° to-45 ° with inner line with the negative angle that horizontal line became of the outer end of crossing opening.
