Abstract
The utility model discloses a hole lathing manufacturing tool for special-shaped workpieces, which comprises a bottom die. A chip removal hole is arranged at the axis of the bottom die, a first positioning hole and a second positioning hole are arranged at eccentric positions of the bottom die, a first positioning pin is disposed in the first positioning hole, a U-shaped bottom plate with an opening at one end is arranged on the bottom die and can rotate around the first positioning pin, two open ends of a pressure plate are positioned on a workpiece and are used for pressing the workpiece, and a second positioning pin is disposed in the second positioning hole, contacts with a side wall of the workpiece and is used for preventing the workpiece from sliding laterally. The technical scheme is adopted, the pressure plate arranged on the bottom die can prevent vertical dislocation of the workpiece, and the second plug pin in the second positioning hole can prevent the workpiece from turning horizontally.
Description
Technical field
The utility model relates to a kind of fixture, particularly a kind of car hole fixture of special-shaped workpiece.
Background technology
Workpiece needed earlier workpiece to be positioned before carrying out the car hole.Yet, just carry out the car hole operation.If the location of workpiece is unstable, then can cause the position inaccuracy in car hole, cause substandard products easily, especially just so to some accurate workpiece.And the conventional positioning mode generally is to adopt the mode of alignment pin or screw to be fixed to the border of workpiece.Yet, because workpiece can receive very big impulsive force when the car hole, thereby cause the dislocation of workpiece, and then the precision when having influence on workpiece car hole.
The utility model content
For solving the technical problem that exists in the prior art, the utility model provides a kind of car hole fixture that special-shaped workpiece is carried out the special-shaped workpiece of stable position.
The utility model solves the problems of the technologies described above, and the technical scheme that is adopted is: a kind of car hole fixture of special-shaped workpiece is provided, comprises a bed die, the place, axle center of this bed die is provided with a chip-removal hole, and the eccentric part of this bed die is provided with first locating hole and second locating hole; Be provided with first alignment pin in said first locating hole, it is the U-shaped pressing plate of the rotatable end opening in axle center that said bed die is provided with this first alignment pin, and the two ends of the opening of this pressing plate are positioned on the workpiece and are used to push down workpiece; Be provided with second alignment pin in said second locating hole, this second alignment pin contacts with the sidewall of said workpiece and is used to prevent that said workpiece from sliding to side.
The technique scheme of the utility model is with respect to prior art; Obtainable beneficial effect is: the described car of the utility model hole fixture comprises a bed die, the through hole that the bed die center is provided with; Not only workpiece is played positioning action, and want to play the effect of chip removal; The pressing plate that is provided with on the bed die can prevent that workpiece from dislocating up and down, and second latch in second locating hole can prevent that workpiece from spinning in the horizontal direction.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the part of the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is the sketch map of the said special-shaped workpiece of the utility model;
Fig. 2 is the generalized section of the said special-shaped workpiece of the utility model;
Fig. 3 is the car hole fixture sketch map of the said special-shaped workpiece of the utility model;
Fig. 4 is the generalized section of the said bed die of the utility model;
Fig. 5 is the sketch map of said first latch of the utility model;
Fig. 6 is the sketch map of said second latch of the utility model.
The specific embodiment
In order to make the utility model technical problem to be solved, technical scheme and beneficial effect is clearer, understand,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Like Fig. 1, shown in Figure 2, show the described special-shaped workpiece 10 of the utility model.The two ends of workpiece 10 are polymorphic structures, and the centre of workpiece 10 is provided with through hole 12, the through hole that through hole 12 also promptly need be processed.All arms at through hole 12 places have certain thickness.Be appreciated that the described regular workpiece 10 of the utility model is not limited to the shape of the workpiece 10 shown in the figure.
Like Fig. 3, Fig. 4, Fig. 5, shown in Figure 6; The car hole fixture of the described special-shaped workpiece of the utility model comprises bed die 20, and the place, axle center of this bed die 20 is provided with a chip-removal hole 28; All arms of chip-removal hole 28 have certain thickness; Therefore the shape to the through hole 12 of workpiece 10 is complementary, and certain locating effect is arranged, the effect that can be used to arrange iron filings simultaneously; The eccentric part of bed die 20 is provided with first locating hole 22 and second locating hole 26; Be provided with first alignment pin 23 in first locating hole 22, bed die 20 is provided with the U-shaped pressing plate 24 of an end opening, and pressing plate 24 is that the axle center is rotatable with this first alignment pin 23, and the two ends of these pressing plate 24 openings are positioned on the workpiece 10 and are used to push down workpiece 10; Be provided with second alignment pin 25 in second locating hole 26, this second alignment pin 25 contacts with the sidewall of workpiece 10 and is used to prevent that workpiece 10 from sliding to side.Like Fig. 5, shown in Figure 6; The difference of first alignment pin 23 and second alignment pin 25 is; The external diameter on the top of second alignment pin 25 is greater than the external diameter of bottom, but above-mentioned first alignment pin 23 and second alignment pin 25 only are examples, and the utility model does not limit the shape of two alignment pins.
As shown in Figure 3, the pressing plate 24 that is provided with on the bed die 20 can prevent that workpiece 10 from dislocate up and down, and second latches 25 in second locating hole 26 can prevent that workpiece 10 from spinning in the horizontal direction, so good to the locating effect of workpiece 10.
Above-mentioned explanation has illustrated and has described the preferred embodiment of the utility model; As previously mentioned; Be to be understood that the utility model is not limited to the form that this paper discloses, should do not regard eliminating as, and can be used for various other combinations, modification and environment other embodiment; And can in utility model contemplated scope described herein, change through the technology or the knowledge of above-mentioned instruction or association area.And change that those skilled in the art carried out and variation do not break away from the spirit and the scope of the utility model, then all should be in the protection domain of the utility model accompanying claims.
