Abstract
The utility model relates to a locating jig for an exhaust gas regulating valve seat of an engine. The locating jig comprises a master jig and a slave jig which are separately arranged on the upper side and the lower side. A slotted hole for allowing a workpiece to stretch into is formed in the middle of the slave jig, and a concave-convex snap ring of which the shape is matched with the shape of lower end portion of the workpiece is arranged on the upper portion of the slotted hole, so that when the lower end portion of the workpiece stretches into the slotted hole and is rotated by a certain angle, the lower end portion of the workpiece is clamped. A cavity for allowing the workpiece to stretch into is formed in the middle of the master jig, and a plurality of locating balls which can conduct reciprocating motion in the radial direction are evenly distributed in the cavity, so that after the upper portion of the workpiece stretches into the cavity, the locating balls move inwards in the radial direction to abut against an annular groove in the periphery of the workpiece, and then the workpiece is located. The locating jig is high in locating accuracy and locating speed and good in using effect.
Description
Technical field
The utility model relates to a kind of engine exhaust regulating valve seat localization tool.
Background technology
In prior art, parts in engine are added to man-hour, need to be located accurately parts, to improve the precision of processing.Whether the location of tool is accurate, for the machining accuracy of workpiece, has important impact.
Summary of the invention
The purpose of this utility model is to provide a kind of engine exhaust regulating valve seat localization tool, and this tool positioning precision is high, and locating speed is fast, and result of use is good.
For achieving the above object, the technical solution of the utility model is: a kind of engine exhaust regulating valve seat localization tool, comprise be divided into upper and lower both sides cure mainly tool and sub-tool, described sub-tool middle part offers for allowing workpiece stretch into slotted eye therebetween, described slotted eye top is provided with the concave-convex snap ring adapted with workpiece bottom profile, after when the workpiece bottom, stretching into slotted eye and to turn over certain angle, block the workpiece bottom; The described tool middle part that cures mainly offers for allowing workpiece stretch into die cavity therebetween, be evenly equipped with some location balls that can radially move back and forth in described die cavity, after when workpiece top, stretching into die cavity, the location ball radially inwardly moves and withstands the cannelure of workpiece perimembranous, and workpiece is positioned.
Further, be provided with in the described die cavity that cures mainly tool that ball moves radially passage and the ball that can move back and forth vertically drives slide block, described ball drives the slide block inboard to be provided with ball and is absorbed in groove; During original state, described location ball partly is positioned at ball and moves radially passage, and part is positioned at ball and is absorbed in groove, when described ball drives slide block to move vertically, to locate ball and eject ball and be absorbed in groove, through ball move radially passage inwardly motion withstand the cannelure of workpiece perimembranous.
The beneficial effects of the utility model are the cooperatings that cure mainly tool and sub-tool, and the engine exhaust regulating valve seat is located accurately, and positioning precision is high, and locating speed is fast, and resetting is effective.In addition, this jig structure is simple, and automaticity is high, and easy operating is practical.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment in non-clamp position.
Fig. 2 is the structural representation of the utility model embodiment in clamp position.
Fig. 3 is the schematic top plan view of the sub-tool of the utility model embodiment.
In figure, 1-cures mainly tool, 2-tool, and the 3-slotted eye, 4-concave-convex snap ring, the 5-die cavity, 6-locates ball, the 7-cannelure, the 8-ball moves radially passage, and the 9-ball drives slide block, and the 10-ball is absorbed in groove, 11-workpiece, 12-workpiece bottom.
The specific embodiment
Engine exhaust regulating valve seat localization tool of the present utility model, as shown in Figure 1, 2, 3, comprise be divided into upper and lower both sides cure mainly tool 1 and sub-tool 2, described sub-tool 2 middle parts offer for allowing workpiece 11 stretch into slotted eye 3 therebetween, described slotted eye 3 tops are provided with the concave-convex snap ring 4 adapted with workpiece bottom 12 profiles, after stretching into slotted eye 3 when workpiece bottom 12 and turning over certain angle, block workpiece bottom 12; Described tool 1 middle part that cures mainly offers for allowing workpiece 11 stretch into die cavity 5 therebetween, be evenly equipped with some location balls 6 that can radially move back and forth in described die cavity 5, after when workpiece top, stretching into die cavity 5, location ball 6 radially inwardly moves and withstands the cannelure 7 of workpiece perimembranous, and workpiece is positioned.
Further, be provided with in the described die cavity 5 that cures mainly tool 1 that ball moves radially passage 8 and the ball that can move back and forth vertically drives slide block 9, described ball moves radially passage 8 and with described ball, drives the slippage passage 13 of slide block 9 to connect and orthogonal.Described ball drives slide block 9 inboards to be provided with ball and is absorbed in groove 10, and the degree of depth that described ball is absorbed in groove 10 is less than the diameter of locating ball 6, therefore location ball 6 can only partly be absorbed in ball, is absorbed in groove 10.During original state, ball is absorbed in groove 10 and just faces ball and move radially passage 8, described location ball 6 parts are positioned at ball and move radially passage 8, part is positioned at ball and is absorbed in groove 10, when described ball drives slide block 9 to move vertically, because can't all being absorbed in ball, ball is absorbed in groove 8, therefore, at ball, drive under the common squeezing action of slide block 9 and slippage passage 13 thereof, to locate ball 6 ejects ball and is absorbed in groove 10, move radially passage 8 through ball and inwardly move and withstand the cannelure 7 of workpiece perimembranous, reach the purpose of locking positioning workpiece.When workpiece will exit, ball drives slide block 9 first to return initial position, and then sub-tool 2 drive workpiece outwards move, and workpiece will be located ball 6 top rollback pearls and is absorbed in groove 10.In the present embodiment, can adopt the type of drive such as manual or pneumatic, in conjunction with spring mechanism as shown in Fig. 1,2, control described ball and drive moving axially of slide block 9.
Be more than preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model, when the function produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
