Abstract
The utility model relates to a cylindrical threaded clamp, which comprises a middle connecting cylinder (1), a lower pull rod (2) and an upper pull rod (3). A bolt (4) is arranged in the middle connecting cylinder (1); a bolt shank passes through the through hole of the bottom of the middle connecting cylinder (1) and is screwed in the internal threaded hole of the upper pull rod (3); the inner surface of a bolt cap and the inner surface of the bottom of the middle connecting cylinder (1) are laminated; the external threaded section of the lower pull rod (2) is screwed in the middle connecting cylinder (1); and one end of the lower pull rod (2) and one end of the upper pull rod (3) are respectively fixedly connected with a wedge-shaped clamp. When a testing machine works, the lower pull rod is driven by the wedge-shaped clamp to downwards move, and a drawing force generated by the testing machine is transferred to the bolt by the lower pull rod and the middle connecting cylinder, and thereby, the overall mechanical property of the bolt is detected. The cylindrical threaded clamp can detect the overall mechanical properties of smaller bolts and has the characteristics of simple structure, convenient testing, convenient and fast test and accurate and reliable result.
Description
One, technical field
The present invention relates to a kind of frock clamp, specifically is a kind of tubular screw-type anchor clamps.
Two, background technology
At present, also the whole mechanics of bolt is detected frock, and require bolt is carried out whole mechanics detection in the technical manual of bolt at engine at physics and chemistry mechanics detection range.The detection of existing bolt all is to connect or the direct clamping of Wedge gripping by existing screw thread anchor clamps, and is shorter because of bolt length, can not carry out direct clamping to it, so need design the special tooling that can carry out the bolt detection.
Three, summary of the invention
For overcome exist in the prior art can not the present invention proposes a kind of tubular screw-type anchor clamps to the deficiency of the direct clamping of bolt.
Connecting cylinder, lower link and upper connecting rod in the middle of the present invention includes, wherein, there is the via hole of body of bolt the center at the bottom of the end tube of middle connecting cylinder.The endoporus of middle connecting cylinder is a threaded hole, and its internal diameter is with the external diameter of lower link, and greater than the external diameter of nuts.Lower link one end surfaces has the external thread with middle connecting cylinder screw-internal thread fit.There is internal thread hole center, upper connecting rod one end termination; The diameter of this internal thread hole is with the external diameter of body of bolt, and bolt screws in this internal thread hole.The length of upper connecting rod internal thread hole should satisfy bolt and reliably be connected with this upper connecting rod.
During use, in the middle of bolt packed in the connecting cylinder, make body of bolt pass in the middle of the via hole of connecting cylinder tube bottom, screw in the internal thread hole of upper connecting rod; Inside surface at the bottom of the inside surface of nuts and the middle connecting cylinder tube is fitted.The external thread section of lower link is screwed in the middle connecting cylinder.One end of lower link and upper connecting rod is fixedlyed connected with Wedge gripping respectively.When testing machine is worked, drive lower link by Wedge gripping and move downward, and the tensile force that testing machine produces is delivered on the bolt, thereby realized the whole mechanics performance detection of this bolt by lower link and middle connecting cylinder 1.
By the technical solution used in the present invention, the two ends of bolt are connected with frock on the testing machine respectively by lower link and upper connecting rod, make less bolt can carry out whole mechanics performance detection.The present invention has simple in structure, and test is convenient, and convenient test is quick, and the result is characteristics accurately and reliably.

Five, embodiment
Present embodiment is a kind of tubular screw-type anchor clamps.Connecting cylinder 1, lower link 2 and upper connecting rod 3 in the middle of comprising, wherein, middle connecting cylinder 1 is a thin cylinder, and at the bottom of an end of this centre connecting cylinder 1 has tin; There is the via hole of body of bolt the tube center, the end of middle connecting cylinder 1, and the internal diameter in this hole is greater than the external diameter of bolt 4 bars, and middle connecting cylinder 1 and bolt 4 clearance fit.The endoporus of middle connecting cylinder 1 is a threaded hole, and its internal diameter is with the external diameter of lower link 2, and greater than the external diameter of nuts; The tube end adjacent of the endoporus of middle connecting cylinder 1 and middle connecting cylinder 1, connecting cylinder 1 internal circular surfaces has technology groove in the middle of the ring.The length of middle connecting cylinder 1 endoporus is with the length sum of nuts and lower link 2 thread segments.The thickness of middle connecting cylinder 1 housing should satisfy the requirement of strength of test.
Upper connecting rod 3 also is cylindrical rod member, and there is internal thread hole center, an end termination; The diameter of this internal thread hole is with the external diameter of body of bolt, and bolt 4 screws in this internal thread hole.The length of upper connecting rod 3 internal thread holes should satisfy bolt 4 and reliably be connected with this upper connecting rod 3.
During use, in the middle of bolt 4 packed in the connecting cylinder 1, make body of bolt pass in the middle of the via hole of 1 bottom of connecting cylinder, screw in the internal thread hole of upper connecting rod 3; Inside surface at the bottom of 1 of the inside surface of nuts and the middle connecting cylinder is fitted.The external thread section of lower link 2 is screwed in the middle connecting cylinder 1.One end of lower link 2 and upper connecting rod 3 is fixedlyed connected with Wedge gripping respectively.When testing machine is worked, drive lower link 2 by Wedge gripping and move downward, and the tensile force that testing machine produces is delivered on the bolt 4, thereby realized the whole mechanics performance detection of this bolt by lower link 2 and middle connecting cylinder 1.
