Detailed description of the invention
The utility model provides a kind of jig arm to extend the design of improved positioning structure, for enabling your juror have a better understanding and awareness the purpose of this utility model, feature and effect, now coordinates embodiment and accompanying drawing to describe in detail as rear:
Consult shown in Fig. 1 to Fig. 9 A, the utility model provides a kind of jig arm to extend improved positioning structure, includes:
One chuck body 10, this chuck body 10 has the interlaced pivot group of two jig arm 11 on a pivot 14, two jig arm 11 are formed with two hands of one 12 respectively toward downward-extension, and two jig arm 11 other ends offer a slot 131 respectively on oblique two oblique arm 13, two oblique arms 13 extending to form one; Two folder jaws 20, this two folders jaw 20 connects a clamping limb 21 respectively, and clamping limb 21 is connected with an extension rod 22, extension rod 22 then plugs slippage in the slot 131 of chuck body 10; Two hands are connected with a positioner 30 between 12; It is mainly:
This slot 131 is close to being provided with a support member 40 below front end, and extension rod 22 and support member 40 contact surface 221,401 suppress concave convex texture a, to increase friction; One spreader spring 50, this spreader spring 50 is sheathed on aforementioned pivot 14, two push rods 51,52 of spreader spring 50 up and fasten extension rod 22 with the overhead kick 511,521 of end respectively and be suppressed with on the end face 222 of concave convex texture b, make spreader spring 50 have expansion folder jaw 20 concurrently and compressing extension rod 22 makes it not easily parallel with stressed.
Consult shown in Fig. 3, when positioner 30 discharges its location, and make spreader spring 50 push two folder jaws 20 open, now because two extension rods 22 do not stretch, two folder jaws 20 open the width that distance is 1 W.
Consult shown in Fig. 4, with pivot 14 pivot joint between two jig arm 11, worn group spreader spring 50 while pivot 14 pivot joint, and make the overhead kick 511,521 of push rod 51 end of spreader spring 50 fasten extension rod 22 to be suppressed with on the end face 222 of concave convex texture b.
Consult shown in Fig. 5, two extension rods 22 pull outward the exhibition of stretching, then two folder jaws 20 open distance for 3W, and two extension rod 22 ends are also provided with downward projection 223, are able to the stop as two extension rod 22 limit of stretch using this projection 223, in case extension rod 22 is deviate from.
Consult Fig. 6,7,8, two extension rod 22 contact surfaces 221 shown in 9A suppress concave convex texture a, support member 40 contact surface 401 also suppresses concave convex texture a, so concave convex texture a can not hinder the expanding-contracting action (as shown in Figure 8) of extension rod 22, but when press from both sides jaw 20 stressed reach extension rod 22 front end stressed time, engage each other so extension rod 22 front end can be pressed down and force between concave convex texture a, and form tension resistance, extension rod 22 can not be drawn out, and effectively be produced leverage and clamping working substance.The shape of aforementioned support member 40 must be a pole shape.
Consult shown in Fig. 9 B, two extension rod 22 contact surfaces 221 suppress concave convex texture a, support member 40 is located at push rod 51 respectively, 52 sides, its contact surface 401 also suppresses concave convex texture a, so concave convex texture a can not hinder the expanding-contracting action (as shown in Figure 8) of extension rod 22, but when press from both sides jaw 20 stressed reach extension rod 22 front end stressed time, extension rod 22 front end can be pressed down and force between extension rod 22 upper side concave convex texture a and engage each other, and form tension resistance, extension rod 22 also can not be drawn out, and effectively be produced leverage and clamping working substance.The shape of aforementioned support member 40 must be a pole shape.
Consult shown in Figure 11 to Figure 12, it comprises one first support member 41 and is located at slot 131 close to below front end, one second support member 42, first, two support members 41, 42 be located at extension rod 22 bear downforce to angular direction, namely the second support member 42 is located at position, slot 131 oblique upper, accordingly, can carry out flexible and without hindrance smoothly when extension rod 22 does not bear pressure, and when extension rod 22 bears downforce, bottom surface and end face 222 concave convex texture a, b is then with first, two support members 41, the concave convex texture a of 42 engages, and more efficiently formation tension resistance, extension rod 22 can not be drawn out, and effectively produced leverage and clamping working substance.The shape of first and second support member 41,42 aforementioned must be a pole shape.
Consult shown in Figure 13, support member 43 of the present utility model is also set as plate support 43, and plate support 43 surface is also provided with concave convex texture a.
Above-mentioned from it, jig arm of the present utility model extends improved positioning structure, really for this area head sees and meet the condition of the novelty of utility model patent, and its comprehensive innovative design, meet the requirement of the progressive of new patent, and its spreader spring expansion two folder jaw suppresses extension rod simultaneously, extension rod and support member are installed with concave convex texture, extension rod can be avoided to be drawn out and to lose its grip force, meet good industry applications.
Be that technical characteristic of the present utility model is specifically described for preferred embodiment of the present utility model above; Person skilled in the art can carry out changing and revise to the utility model not departing under spirit of the present utility model and principle, but this type of changes and revises, and all should be covered by the category that the application's the scope of the claims defines.
In sum, the utility model provides a kind of jig arm to extend improved positioning structure, and it indeed reaches all objects of the present utility model, the space kenel of its combining structure another has no in like product, also, before not being disclosed in application, having met the regulation of Patent Law, therefore filed an application in accordance with the law.
