The ends of the right wire clamping block andthe left wire clamping block adopt two similar 7-shaped right angle structures; the positioning block is arranged in the space between the right wire clamping block and the left wire clamping block;two separated threads segments are arranged at one end of the screw; and the left threads segment and the right threads segment have reversed screw directions and equal screw pitches. The axis segmentbetween the left threads segment and the right threads segment and the positioning block are in rotatable connection in circumferential direction and fixed connection in axial direction; and the handle is fixedly arranged at the other end of the screw. In the conducting wire clamp provided by the utility model, the two wire clamping blocks arranged at two ends are connected with the screw, the two clamping surfaces of the wire clamping blocks are utilized to clamp the conducting wire, thereby guaranteeing the rectilinear motion of the tested conducting wire and improving the measuring accuracy; meanwhile, the wire clamping blocks and the conducting wire are in line contact, thereby avoiding wire casing damage.
Description
Technical field:
The utility model relates to the pull force tester of automotive wire bundle, particularly a kind of lead anchor clamps that are used for tension tester.
Background technology:
The wire harness tension tester is used for the pulling force of wire harness is tested, to check its reliability.What the clamp mechanism of tradition wire harness tension tester adopted is eccentric mechanism, this mechanism is made of clamp piece, eccentric wheel clamp piece, manually rotating eccentricity wheel clamp piece clamps line-transect, therefrom line-transect is tangent (being to become point to contact between them) with eccentric wheel clamp piece as can be seen, the clamped distortion of line-transect this moment, depart from mutually at center and actual motion center when the clamp piece clamps with eccentric wheel clamp piece, cause lead to become oblique tension state, thereby in measuring process, exist than mistake, and this clamp mechanism damages rubber-insulated wire easily.
The utility model content:
The purpose of this utility model is to provide a kind of lead anchor clamps that are used for tension tester, the described this lead anchor clamps that are used for tension tester to solve lead anchor clamps that prior art is used for tension tester owing to lead between for contacting the technical matters that causes measuring error to damage rubber-insulated wire more greatly and easily.
The purpose of this utility model is achieved through the following technical solutions: this lead anchor clamps that are used for tension tester, by left clamp piece, locating piece, right clamp, screw rod and handle constitute, the end view of right clamp piece and left clamp piece is two " 7 " font right-angle structures of mirror image mutually, this right side clamp piece constitutes the lead clamping face with relative side, left clamp piece upper end, be provided with locating piece in the space between right clamp piece and the left clamp piece, screw rod one end is provided with the thread segment of two sections separation, opposite and the pitch of the rotation direction of one section screw thread in the left side and the one section screw thread in the right equates on the screw rod, the one section screw thread in the left side is connected by screw thread pair on left side clamp piece and the screw rod, one section screw thread is connected by screw thread pair on the right of on right clamp piece and the screw rod, a left side on the screw rod, shaft part and locating piece form circumferentially rotatable between right two sections screw threads, the connection of axial restraint, handle are fixed at the screw rod other end.
One section screw thread of the screw thread and the screw rod left side in the clamp piece of a left side is a right-hand thread, and one section screw thread of the screw thread in the right clamp piece and screw rod the right is a left-hand thread (LHT).
The clamping face of left side clamp piece and right clamp piece is provided with the annular knurl decorative pattern.
Certainly, the annular knurl decorative pattern on the clamping face also can be substituted by other structure that can increase friction force, such as the salient point of array, and vertical striped etc.
On locating piece, be fixed with the location pilot pin parallel, correspondingly on left clamp piece and right clamp piece, offer pilot hole and cooperate with this location pilot pin with screw rod.
Principle of work of the present utility model is: since between clamp piece and the screw rod for screw thread pair is connected, when rotary handle, about two clamp pieces can closed clamping wire or unclamp lead.Because what left and right sides clamp piece adopted is that the plane is to the folder mode, its move toward one another distance is consistent, the symcenter position of two clamp pieces is consistent with the actual motion center all the time, lead between two clamp pieces also with the operational centre position consistency, so just guaranteed the motion that is in line of tested lead.In addition, two clamp pieces adopt the plane to folder, and lead becomes face contact with the clamp piece, and two clamp piece clamp faces adopt annular knurl design, the friction force between increase and the lead, like this lead can be pressed from both sides more firm, the line skin is easy damaged not also.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with two clamp pieces at the lead anchor clamps two ends that are used for tension tester and is connected with screw rod, the circumferential movement of handle is converted to the transverse movement of clamp piece by screw rod; Because the thread rotary orientation of left clamp piece and right clamp piece is opposite, make that the direction of motion of two clamp pieces is opposite when screw rod rotates, the symcenter position of two clamp pieces is consistent with position, actual wire operational centre all the time, so just guarantee the motion that is in line of tested lead, improved measuring accuracy; Simultaneously, two clamp pieces adopt the plane to clamping structure, and lead becomes face to contact with the clamp piece, the friction force between increase and the lead, like this lead can be pressed from both sides more firm, the line skin is easy damaged not also.If the one section screw thread in the screw thread in the left clamp piece and the screw rod left side adopts right-hand thread, one section screw thread of screw thread in the right clamp piece and screw rod the right adopts left-hand thread (LHT), this set is fit to general right-handed operators, when clockwise rotating handle, because screw rod only rotates, does not produce laterally and move, therefore make left clamp piece and right clamp piece move toward one another, promptly distance between the two reduces, and therebetween wire clamp is applied tight power; When rotating counterclockwise handle, left clamp piece and the opposing motion of right clamp piece, promptly distance between the two increases, and decontrols lead therebetween.Clamping face by left clamp piece and right clamp piece is provided with the annular knurl decorative pattern, and this can increase the friction factor between lead and the clamping face, and then increases friction force.Between locating piece and the left and right sides clamp piece bearing pin is set and cooperates with pin-and-hole, this can guarantee further that left and right clamp piece along the motion of screw rod direction, guarantees that lead therebetween is subjected to the holding force effect perpendicular with clamping face.
