Abstract
The utility model relates to a clamp for a cylindrical-structure box body. The clamp for the cylindrical-structure box body resolves the problems that an existing tool for the cylindrical-structure box body deforms the box body easily in the clamping process and results in serious deviation of positions of a bearing hole and a positioning hole. The clamp for the cylindrical-structure box body comprises a shell body, wherein a positioning plate, a traction bolt, a guide sleeve, a spring guide bolt and a lower base are sequentially arranged in the axis position of the shell body from top to bottom, a lining is fixed at the inner side of the shell body, a guide sleeve reset spring is arranged between the spring guide bolt and the guide sleeve, a clamping sleeve is sleeved outside the lower portion of the guide sleeve, a bolt reset spring is arranged between the clamping sleeve and the lower base, an arc annular groove is formed in the lateral surface of the lower portion of the traction bolt, a steel ball is fixed at the upper portion of the clamping sleeve, a cam ring is fixed at the upper portion inside the lining, the inner wall of the cam ring is tightly attached to the steel ball, the surface of the inner wall of the cam ring inclines inwards, an oil cylinder is arranged inside the shell body above the cam ring, and a bolt plug is arranged at the lower portion inside the lining. The clamp for the cylindrical-structure box body is reasonable and reliable in structural design, parts are clamped conveniently, operation time of workers is shortened, and work efficiency is improved.
Description
Technical field
The utility model relates to the machining positioner, is specially a kind of core structure casing anchor clamps.
Background technology
Core structure gear box casing volume is big, shell wall is thin, the housing profile lacks effectively reliable technology location and compresses a little, if adopt traditional plane and two pits method design frock, in process, housing distortion can occur, cause the dead eye of housing finished product and assembling seriously overproof with the position of positioning hole degree.
Summary of the invention
The utility model is contained in and easily causes box deformation to cause dead eye and the serious overproof problem of position of positioning hole in the clamping process in order to solve existing core structure casing recruitment, and a kind of core structure casing anchor clamps are provided.
The utility model is to adopt following technical scheme to realize: core structure casing anchor clamps, comprise the housing that has lancing door, the place, axle center of housing is disposed with location-plate under last, draw bolt, guide pin bushing, spring guiding bolt and lower bottom base, fixedly there is lining the housing inboard, be provided with the guide pin bushing back-moving spring between spring guiding bolt and the guide pin bushing, guide pin bushing is with the gripping sleeve that the bottom is provided with ring-shaped step outward, be provided with the hitching post back-moving spring between gripping sleeve and the lower bottom base, the lower side of draw bolt is provided with the arcuation annular groove, the steel ball that is positioned at the arcuation annular groove is fixedly arranged at gripping sleeve top, upper fixed has the cam ring that is through on the draw bolt in the lining, the inwall of cam ring is close to steel ball, and the cam ring inner wall surface of steel ball below slopes inwardly, be provided with oil cylinder in the housing of cam ring top, the below is provided with the embolism that is supported on the gripping sleeve step in the lining.
During operation, use on the workpiece original screwed hole or at the new technology screwed hole of rational position design, draw bolt is connected with workpiece, subsequently work piece hoisting is advanced clamp body, check alignment pin and each locating surface connection status, oil cylinder is pressurizeed, embolism moves down under the effect of hydraulic oil, drives gripping sleeve and steel ball and moves downward, and this moment, steel ball pushed and drop-down draw bolt to the inside in the effect on cam ring inclined-plane, the drive draw bolt moves downward, and finally strains workpiece; After operation is finished, under the effect of hitching post back-moving spring and guide pin bushing back-moving spring, reset, overcome the recruitment of existing core structure casing and be contained in and easily cause box deformation to cause the serious overproof problem of dead eye and position of positioning hole in the clamping process.
The utility model reasonable in design is reliable, under the acting in conjunction of the supporting of the tightening force of draw bolt and locating surface, make workpiece when clamping, almost not have distortion, guaranteed the position degree requirement of each machining hole, solved cartridge type housing process middle (center) bearing hole and assembling effectively with the overproof problem of position of positioning hole degree, clamping parts is convenient and reliable, has reduced workman's operating time, improved operating efficiency, and in light weight.
