Abstract
The invention discloses a fixture for a box body with a cylinder type structure. The fixture for the box body with the cylinder type structure solves the problems that a box body is easy to deform to lead to being seriously overproof at the positions of a bearing hole and a location hole in a clamping process of an existing tool of a box body with the cylinder type structure. The fixture for the box body with the cylinder type structure comprises a shell body. A location plate, a draw bolt, a guide sleeve, a spring guide bolt and a lower bottom base are arranged at the axis center position of the shell body from top to bottom in sequence. A lining is fixed on 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 with the lower portion provided with an annular step is arranged outside the guide sleeve in an enclosing manner. A bolt pillar reset spring is arranged between the clamping sleeve and the lower bottom base. An arc-shaped circular groove is formed in the lateral face of the lower portion of the draw bolt. A steel ball is fixed on the upper portion of the clamping sleeve. A cam ring is fixed on the upper side in the lining. The inner wall of the cam ring is tightly appressed to the steel ball and the surface of the inner wall of the cam ring is inclined inwards. An oil cylinder is arranged above the cam ring inside the shell body. A bolt plug is arranged on the lower portion in the lining. The fixture for the box body with the cylinder type structure is reasonable and reliable in design. Components can be convenient and reliable to clamp. Worker operation time can be reduced and work efficiency can be improved.
Description
Technical field
The present invention relates to machining positioner, be specially a kind of Fixture for box body with cylinder type structure.
Background technology
Core structure gear box casing volume is large, shell wall is thin, housing profile lacks locating and compression point effectively reliably, if adopt traditional plane and two pits method design frock, in process, there will be housing distortion, cause the dead eye of housing finished product and assembling position of positioning hole degree seriously overproof.
Summary of the invention
The present invention is contained in clamping process to solve the recruitment of existing core structure casing the problem easily causing box deformation to cause dead eye and position of positioning hole seriously overproof, provides a kind of Fixture for box body with cylinder type structure.
The present invention adopts following technical scheme to realize: Fixture for box body with cylinder type structure, comprise the housing with lancing door, the axle center place of housing is disposed with location-plate under upper, draw bolt, guide pin bushing, spring guiding bolt and lower bottom base, case inside is fixed with lining, guide pin bushing back-moving spring is provided with between spring guiding bolt and guide pin bushing, guide pin bushing overcoat has bottom to be provided with the gripping sleeve of ring-shaped step, hitching post back-moving spring is provided with between gripping sleeve and lower bottom base, the lower side of draw bolt is provided with arcuation annular groove, gripping sleeve top is fixed with the steel ball being positioned at arcuation annular groove, in lining, top is fixed with the cam ring be through on draw bolt, the inwall of cam ring is close to steel ball, and the cam ring inner wall surface below steel ball slopes inwardly, oil cylinder is provided with in housing above cam ring, in lining, below is provided with the embolism be supported on gripping sleeve step.
During operation, to use on workpiece original screwed hole or design new technique screwed hole at rational position, draw bolt is connected with workpiece, subsequently work piece hoisting is entered clamp body, check alignment pin and each locating surface connection status, oil cylinder is pressurizeed, embolism moves down under the effect of hydraulic oil, and drive gripping sleeve and steel ball to move downward, the now effect of steel ball on cam ring inclined-plane extrudes and drop-down draw bolt to the inside, drive draw bolt moves downward, and finally strains workpiece; After operation completes, reset under the effect of hitching post back-moving spring and guide pin bushing back-moving spring, overcome the recruitment of existing core structure casing and be contained in clamping process the problem easily causing box deformation to cause dead eye and position of positioning hole seriously overproof.
Reasonable in design of the present invention is reliable, under the acting in conjunction of the tightening force of draw bolt and the supporting of locating surface, make workpiece when clamping almost without distortion, ensure that the position degree requirement of each machining hole, efficiently solve cylindrical shell process axis bearing bore and the overproof problem of assembling position of positioning hole degree, clamping parts is convenient and reliable, decreases operative's time, improve operating efficiency, and lightweight.
