Abstract
The invention relates to a floating clamping jaw for internal diameter portion clamping. The floating clamping jaw comprises a clamping jaw body, a floating base, a floating shaft pin, an adjusting screw, a first riveting screw, a locking screw and nylon blocks. The floating base is arranged at the upper end of the clamping jaw body. The clamping jaw body is connected with the floating base through the floating shaft pin, and the floating base can rotate around the floating shaft pin. The adjusting screw is further arranged between the clamping jaw body and the floating base and used for adjusting the floating base to enable the floating base to rotate within a certain angle. The lower end of the floating shaft pin is fixedly connected with the clamping jaw body through the first riveting screw. The upper end of the floating shaft pin is connected with the floating base through the locking screw in a fastened mode. Grooves are further formed in the two ends of the floating base. The nylon blocks are arranged in the grooves. When the floating clamping jaw for internal diameter portion clamping is used, the internal diameter portion of a thin-wall part is clamped through three floating clamping jaws for internal diameter portion clamping in an abutted mode, and meanwhile the rotating angles of the three floating bases can be adjusted through the adjusting screws under the action of the floating shaft pins so that the three floating bases can be aligned with the positioning reference of the thin-wall part; the floating clamping jaw for internal diameter portion clamping is higher in practicality.
Description
Technical field
The present invention relates to a kind of floating claw, particularly relate to a kind of clamping internal diameter floating claw.
Background technology
Common three-jaw self-centering chuck is that a kind of utilization is distributed on moving radially of three movable jaws on chuck body, and the machine tool component clamping workpiece and locate, it is widely used in every field.But when some high-precision thin-walled parts processed by needs, if adopt the method for internal diameter clamping to thin-walled parts, because self precision of common self-centering three-jaw chuck is lower than part positioning datum precision, so easily produce when machining high-precision thin-walled parts lose circle, position of related features departs from and the problem such as the dimension overproof heart, bring inconvenience to actual processing, actual process requirements cannot be met.
Summary of the invention
The present invention seeks to provide a kind of easy for installation to overcome the deficiencies in the prior art, internal diameter can be adopted to clamp thin-walled parts, and positioning datum and the high clamping internal diameter floating claw of machining accuracy.
For achieving the above object, the technical solution used in the present invention is: a kind of clamping internal diameter floating claw, comprises jaw body, floating seat, float pivot pin, adjustment screw, the first self-clinching stud, lock-screw and nylon block; Described jaw body upper end is provided with floating seat; Described jaw body is connected by the pivot pin that floats with between floating seat, and floating seat can rotate around floating pivot pin; Also being provided with adjustment screw between described jaw body and floating seat, rotating in certain angle for regulating floating seat; Described floating pivot pin lower end is fixedly linked by the first self-clinching stud and jaw body; Described floating pivot pin upper end is connected by lock-screw and floating seat are fastening; Described floating seat two ends are also provided with groove; Nylon block is provided with in described groove.
Preferably, described groove is U-shaped; Nylon block is fixed in a groove by the counterbore on nylon block by described second self-clinching stud.
Preferably, the material of described nylon block is made up of ABS plastic.
Preferably, the material of described floating seat, float pivot pin, adjustment screw and lock-screw is 40Cr.
Preferably, described floating seat is L-type.
Due to the utilization of technique scheme; the present invention compared with prior art has following advantages: the clamping internal diameter floating claw of the present invention program; its structure is simple; easy for installation; during use, three clamping internal diameter floating claws withstand the internal diameter of thin-walled parts; thus thin-walled parts is clamped; simultaneously three floating seats regulate the anglec of rotation of floating seat under the effect of floating pivot pin by adjustment screw; thus the positioning datum of centering thin-walled parts; and then meet actual process requirements, there is higher practicality and the value of carrying out large-scale promotion.
