Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a portable stock verifying attachment, including hydraulic pump 1, end cover 2 is installed to the preceding terminal surface screw thread of hydraulic pump 1, one side screw thread that hydraulic pump 1 was kept away from to the medial surface of end cover 2 is installed fixed pincers 3, fixed pincers 3 include annular body 4 and centre bore 5, centre bore 5 includes face of cylinder 6 and round platform 7, T type groove 8 has been seted up to the inner wall of round platform 7, the medial surface slidable mounting in T type groove 8 has movable clamp 9, movable clamp 9 includes batter post 10, splint 11 and with T type groove 8 complex slider 12, one side that batter post 10 was kept away from to splint 11's surface is provided with protruding crowd 13 of toper.

In this embodiment, hydraulic pump 1 has hollow structure, can supply the stock to pass, it removes to drive fixed pincers 3 during the operation, thereby accomplish the inspection of drawing of stock, because prior art, no longer giving details here, end cover 2 can avoid the activity to press from both sides 9 to fall out from T type groove 8 with fixed pincers 3 equipment back, play limiting displacement, the setting up of end cover 2 makes the dismouting of fixed pincers 3 on hydraulic pump 1 more convenient, convenient the change, fixed pincers 3 are used for fixed stock, and fixed pincers 3 need not manual regulation in the use, clamping to the stock is more stable, it is more convenient to use, and spare part still less, the production cost is reduced, and is more practical.

Specifically, the number of the T-shaped grooves 8 and the number of the movable clamps 9 are not less than three.

In this embodiment, the acting force of the three or more groups of movable clips 9 on the axial surface of the anchor rod is more balanced, and the anchor rod is more firmly fixed.

Specifically, the cross section of the circular table surface 7 is trumpet-shaped and opens to the end far away from the cylindrical surface 6.

In this embodiment, when drawing the stock, the frictional force opposite direction between splint 11 and the stock, the stock can make activity clamp 9 have gliding trend in T type groove 8 to splint 11's effort, and the direction is the reverse of round table face 7 opening direction, consequently the trend that multiunit activity clamp 9 is drawn close to the stock, activity clamp 9 is just bigger to the effort of stock, it is firmer to the clamping of stock to make fixing tongs 3, the condition of skidding is difficult to appear between stock and the fixing tongs 3, make the inspection value of stock more accurate.

Specifically, a pressure spring 14 is welded between one side of the inner wall of the T-shaped groove 8, which is far away from the cylindrical surface 6, and the outer surface of the sliding block 12.

In this embodiment, the compressed spring 14 has a reaction force after being extruded, and can continuously have an acting force on the slider 12, and in the drawing process, the slider 12 cannot jump due to shaking, so that the action force of the movable clamp 9 on the anchor rod is prevented from being disconnected, and the drawing process is more stable.

The utility model discloses a theory of operation and use flow: during the use, twist end cover 2 on fixed pincers 3, avoid movable clamp 9 to fall out from T type groove 8, twisting the end cover 2 other end piston head on hydraulic pump 1, it is comparatively convenient to the change of fixed pincers 3, the stock that will await measuring passes hydraulic pump 1, end cover 2 and fixed pincers 3, when hydraulic pump 1 moves, fixed pincers 3 move to the direction of keeping away from hydraulic pump 1, the frictional force opposite direction between splint 11 and the stock, the stock can make movable clamp 9 have gliding trend in T type groove 8 to the effort of splint 11, and the direction is the reverse of round table face 7 opening directions, therefore the trend that multiunit movable clamp 9 draws close to the stock, the effort of movable clamp 9 to the stock is just bigger, and multiunit movable clamp 9 is more balanced to the effort of stock axial plane, make fixed pincers 3 more firm to the clamping of stock, the condition that is difficult to appear skidding between stock and the fixed pincers 3, make the inspection value of stock more accurate, need not to manually adjust fixed pincers 3 in the use, it is more convenient to use, contrast prior art, zero part still less, production cost is reduced, and is more practical.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
