Abstract
The utility model discloses a three-jaw special for inner cavity boring of an encircling diamond thin-wall bit. The three-jaw comprise a chuck, wherein a plurality of jaws are arranged on the chuck in a sliding way, and are fixedly connected with an arc-shaped support plate; the upper ends of the jaws are connected with reinforcing arms; the reinforcing arms are connected with arc-shaped support plates; and the arc-shaped support plates are coaxial, and are distributed uniformly around a circle center. The three-jaw has a simple structure, and a workpiece can be rapidly clamped, so that the labor intensity of workers is lowered, time is saved, the rejection rate is lowered, and the use cost is lowered.
Description
Technical field:
The utility model relates to the clamp for machining field, and concrete is the special-purpose three-jaw of a kind of encircling type diamond thin-wall drill bit inner chamber bore hole.
Background technology:
At present; The part that known lathe three-jaw contacts with the workpiece width about 1 centimeter of only having an appointment is when the relatively thinner workpiece of clamping, like the easy deformation then of big slightly workpiece firmly; Then need round iron plate lining man-hour as adding at placement of steel pipe inner chamber and the corresponding diameter of endoporus with conventional way; But blank steel tube inner hole diameter differs, unfavorable batch machining, and waste time and energy.
The utility model content:
The purpose of the utility model provides the special-purpose three-jaw of a kind of encircling type diamond thin-wall drill bit inner chamber bore hole, when the special-purpose workpiece of processing, and ability quick-clamping workpiece, thus reducing working strength of workers and save time, the rate of reducing the number of rejects and seconds reduces production costs greatly.
The technical scheme of the utility model:
The special-purpose three-jaw of encircling type diamond thin-wall drill bit inner chamber bore hole; Comprise chuck, be slidingly fitted with a plurality of claws on the chuck, it is characterized in that: be fixedly connected with the arc supporting plate on the described claw; The claw upper end is connected with the reinforcement arm, and described reinforcement arm is connected with the arc supporting plate.
The special-purpose three-jaw of described encircling type diamond thin-wall drill bit inner chamber bore hole is characterized in that: described arc supporting plate coaxial and around the center of circle all with distribution.
The advantage of the utility model:
The utility model is simple in structure, ability quick-clamping workpiece, thus reduce working strength of workers and save time, the rate of reducing the number of rejects and seconds, thus reduce use cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the forward sight structure chart of the utility model.
The specific embodiment:
The special-purpose three-jaw of encircling type diamond thin-wall drill bit inner chamber bore hole; Comprise chuck 1; Be slidingly fitted with a plurality of claws 2 on the chuck 1, be fixedly connected with arc supporting plate 3 on the described claw 2, claw 2 upper ends are connected with strengthens arm 4; Described reinforcement arm 4 is connected with arc supporting plate 3, described arc supporting plate 3 coaxial and around the center of circle all with distribute.
Claims (2)
1. the special-purpose three-jaw of encircling type diamond thin-wall drill bit inner chamber bore hole; Comprise chuck, be slidingly fitted with a plurality of claws on the chuck, it is characterized in that: be fixedly connected with the arc supporting plate on the described claw; The claw upper end is connected with the reinforcement arm, and described reinforcement arm is connected with the arc supporting plate.
