Abstract
The utility model provides a sliding post type pressing expanding core clamping mechanism. The mechanism comprises a positioning post base, a sliding post and a pulling rod, wherein the sliding post is arranged between the positioning post base and the pulling rod, the sliding post is matched with the slope of the positioning post base, and the sliding post slides downwards through the acting force of the pulling rod along the positioning post base. According to the mechanism, the sliding post slides downwards along a slot with a certain angle under the stress condition, radial and downward force is exerted by the sliding post on part holes, and the centering clamping and the pulling clamping are achieved.
Description
Technical field
The utility model relates to a kind of cored structure that rises, and relates in particular to a kind of slide column type and presses down the core clamp mechanism that rises.
Background technology
The core mechanism that rises is common mechanism in the jig Design, its objective is in order to make processing parts location, and certain clamping action is arranged.At present both at home and abroad the colleague commonly used centering machine spring ringfeder, slide block, hydraulic pressure plastics etc. are arranged, in slide block, slide column type mechanism, adopt conical or three wedge shape pull bars, with the conical surface or voussoir spreading traveller, its dimension is all in radial direction.We expect that more it has certain drop-down effect for centering machine in part processing, part tightly is attached on the locating surface, thereby makes the element precision of processing higher.
The utility model content
In order to solve existing technical problem in the background technology, the utility model proposes a kind of slide column type and press down the core clamp mechanism that rises, make traveller when stressed along the groove with certain angle toward lower slider, thereby traveller is had radially and downward power hole in piece part.Reach the purpose of centering clamping and drop-down clamping.
Technical solution of the present utility model is: slide column type presses down the core clamp mechanism that rises, comprise locating dowel base, traveller and pull bar, described traveller is arranged between locating dowel base and the pull bar, its special character is: described traveller cooperates with locating dowel base inclined-plane, described traveller by drag-link force along locating dowel base down sliding.
Above-mentioned pull bar is nail shape pull bar.
Arrange and the concavo-convex restoring board that cooperates of traveller on the above-mentioned pull bar.
Be flexibly connected between above-mentioned restoring board and the pull bar.
On the above-mentioned pull bar back-moving spring is set, described back-moving spring is connected with the restoring board lower surface.
Be provided for the gripper shoe that fits tightly with part on the above-mentioned locating dowel base, described gripper shoe and locating dowel base can be the integral type design, also can independent design, and gripper shoe is fixedly connected with the locating dowel base.
The utility model slide column type presses down the core clamp mechanism that rises in order to reach centering and drop-down purpose, make traveller when stressed along the groove with certain angle toward lower slider, thereby traveller is had radially and downward power to hole in piece part, make part tightly be attached on the locating surface, reach the purpose of centering clamping and drop-down clamping, thereby make the element precision of processing higher.
Description of drawings
Fig. 1 is structural representation of the present utility model;
The specific embodiment
Referring to Fig. 1, slide column type of the present utility model presses down the core clamp mechanism that rises, comprise locating dowel base 1, traveller 2, nail shape pull bar 3, back-moving spring 4, restoring board 5 and gripper shoe 6, traveller 2 is arranged between locating dowel base 1 and the nail shape pull bar 3, traveller 2 is suitable with nail shape pull bar 3, the upper end of traveller 2 is stuck with the bottom surface of nail shape pull bar 3, when nail shape pull bar 3 is subject to downward active force, can produce downward thrust to traveller 2, traveller 2 cooperates with locating dowel base 1 inclined-plane, and traveller 2 passes through the active force of nail shape pull bar 3 along locating dowel base 1 down sliding; Arrange and the traveller 2 concavo-convex restoring boards that cooperate 5 on the nail shape pull bar 3, be flexibly connected between restoring board 5 and the nail shape pull bar 3, on the nail shape pull bar 3 back-moving spring 4 is set, back-moving spring 4 is connected with restoring board 5 lower surfaces, back-moving spring 4 can be given restoring board 5 reaction forces, be provided for the gripper shoe 6 that fits tightly with part on the locating dowel base 1, gripper shoe 6 is fixedly connected with locating dowel base 1.
When processing parts, adopt hole in piece part and end face location.After loading onto part, during pulling nail shape pull bar 3, traveller 2 slides along locating dowel base 1, when running into the hole inwall of part, stop, at this moment be used for traveller 2 by the masterpiece on the nail shape pull bar 3, the power effect F on the traveller 2 is in the part hole wall, because traveller 2 is to slide along an angle, so the power F that the hole in piece part inwall is subject to is also along this direction, this power F can be decomposed into the radial component Fx of detent mechanism and along axial component Fy.Part has been realized centering and clamping action under the power Fx effect of three travellers 2 to it, part tightly is attached on the gripper shoe 6 under power Fy effect, has guaranteed the reliable and clamping of axial location.After part machines, remove the pulling force on the nail shape pull bar 3 after, traveller 2 is subject to the thrust of back-moving spring 4, along locating dowel base 1 skewed slot upward sliding, has unclamped radial and axial clamping, thereby part can be taken off easily.
