Abstract
The utility model relates to an adjustable workpiece clamping jaw structure. The adjustable workpiece clamping jaw structure comprises two half clamping jaws, each of the half clamping jaws comprises a jaw head and a jaw body which are connected, the bottom of the jaw body is provided with a transverse groove and a longitudinal groove, and the jaw head is provided with a boss which is in a transverse sliding fit with the transverse groove of the jaw body. The longitudinal groove of the jaw body of each half clamping jaw enables the jaw body to move longitudinally relative to a mechanical arm, and the transverse groove of the jaw body of each half clamping jaw enables the jaw head to move transversely, so that the application range of the adjustable workpiece clamping jaw structure is further expanded and the size limit of a workpiece can be reduced; the position-adjustable claw heads and the position-adjustable claw bodies facilitate the adjustment of the central position of the workpiece; and meanwhile, due to the fact that the jaw heads form a V-shaped clamping section, the contact area on the surface of a shaft-type workpiece is increased, further the shaft-type workpiece can be clamped effectively, and the processing error can be reduced.
Description
Technical field
The utility model relates to a kind of jaw, is specifically related to a kind of adjustable workholding jaw mechanism.
Background technology
In general, as workpiece being fixed on the equipment of processing on the machining equipments such as lathe, all can adopt jaw.And the jaw of using always now as shown in Figure 1, all is to adopt monoblock type, directly upper gripper jaw is fixed on the mechanical arm, controls jaw to the clamping of workpiece by the activity of mechanical arm, and is bigger to the workpiece size restriction, clamping range is little, also the inconvenient artificial workpiece centre of adjusting; Its gripping section adopts the profile of tooth form, can not effectively clamp when shaft-like workpiece is carried out clamping, causes that workpiece is loosening, causes mismachining tolerance.
Summary of the invention
In view of this, the purpose of this utility model provides a kind of adjustable workholding jaw mechanism, has overcome above-mentioned weak point, and is simple in structure, applied widely.
The utility model discloses a kind of adjustable workholding jaw mechanism, be made up of two and half jaws, described half jaw comprises pawl head and pawl body, and described pawl body bottom surface is provided with transverse concave groove and vertical groove, described pawl head is provided with the boss that is slidingly matched with pawl body transverse concave groove, and the pawl head is connected with the pawl body.
Further, described pawl body is connected with the pawl hook bolt.
Further, described transverse concave groove and vertical groove cross sectional shape be in rectangle, triangle or the circular arc any one.
Further, the described pawl head one side corresponding with another half jaw is provided with straight down that the groove cross sectional shape is the gripping section of V-arrangement.
Further, described pawl head convex platform both sides are provided with the dowel hole that arranges along the interval of boss direction, and described pawl head is connected with pawl body pin.
The beneficial effects of the utility model are: the adjustable workholding jaw of the utility model mechanism, and simple in structure, operation and easy to maintenance, low cost of manufacture.By two and half jaws workpiece is carried out clamping, the vertical groove of half jaw pawl body, the pawl body is moved longitudinally with respect to mechanical arm, the transverse concave groove of half jaw pawl body, can make the pawl head carry out horizontal movement, further enlarge the scope of application of the present utility model, reduced the restriction of workpiece size; Pawl head and pawl body that can adjusting position have made things convenient for the position of adjusting workpiece centre, have reduced mismachining tolerance.Adopt the pawl head of the gripping section of V-arrangement, increased the shaft-like workpiece surface contact area, can effectively clamp shaft-like workpiece, reduce because of the loosening mismachining tolerance that causes of workpiece.
Description of drawings
For the purpose, technical scheme and the advantage that make utility model is clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is the jaw schematic diagram of prior art;
Fig. 2 is the novel jaw upward view of this use;
Fig. 3 is jaw graphics of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in the figure, a kind of adjustable workholding jaw mechanism is made up of two and half jaws 1, and 1 pair of workpiece of two and half jaws carries out clamping, and described half jaw 1 comprises pawl head 2 and pawl body 3, and pawl body 3 is connected and fixed with mechanical arm.Described pawl body 3 bottom surfaces are provided with transverse concave groove 4 and vertical groove 5, and described pawl head 2 is provided with the boss 6 that is slidingly matched with pawl body 3 transverse concave grooves 4, and pawl head 2 is connected with pawl body 3.In the piece-holder process, double jaw of workpiece meeting 1 produces the power of different directions, and the boss 6 that is arranged in the groove can make pawl head 2 and 3 of pawl bodies be subjected to retrain its free degree along the influence of the power of groove direction, does not produce the distortion of other directions.
In the present embodiment, described pawl body 3 is connected with pawl head 2 bolts 7, and anti-claw stop body 3 and pawl head 2 produce relative displacement.
In the present embodiment, described transverse concave groove 4 and vertical groove 5 cross sectional shapes are rectangle.
In the present embodiment, described pawl head 2 and another half jaw 1 corresponding one side is provided with straight down that the groove cross sectional shape is the gripping section 8 of V-arrangement, has increased the shaft-like workpiece surface contact area, can effectively clamp shaft-like workpiece.
In the present embodiment, described pawl head 2 convex platforms 6 both sides are provided with the dowel hole 9 that arranges along the interval of boss 6 directions, described pawl head 2 is connected with pawl body 3 pins, in the piece-holder process, can prevent the movement that claw stop head 2 produces along boss 6 directions with respect to pawl body 3, cause the clamping shakiness to workpiece, influence machining accuracy.
The adjustable workholding jaw of the utility model mechanism puts into middle workpiece by 1 pair of two and half jaw and carries out clamping, the clampings that the gripping section 8 of V-arrangement is fit to axial workpiece.The vertical groove 5 of half jaw pawl body 3, pawl body 3 is moved longitudinally with respect to mechanical arm, and the transverse concave groove 4 of half jaw pawl body 3 can make pawl head 2 carry out horizontal movement, further enlarge the scope of application of the present utility model, reduced the restriction of workpiece size; Pawl head 2 and pawl body 3 that can adjusting position have made things convenient for the position of adjusting workpiece centre, have reduced mismachining tolerance.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and not depart from the spirit and scope of the present utility model that appended claims limits.
