Abstract
The utility model discloses a screw stud torque detecting tool. The screw stud torque detecting tool comprises a clamping sleeve. The clamping sleeve is a cylindrical structure. A circular hole passing through the bottom surface of the clamping sleeve is disposed on the center of one end of the clamping sleeve. Screw thread is disposed in the circular hole. A square hole is disposed on the center of the other end of the clamping sleeve. The clamping sleeve comprises a left clamping sleeve and a right clamping sleeve which is symmetrical with the left clamping sleeve round the diameter of the clamping sleeve. One side of the left clamping sleeve is hinged to the right clamping sleeve, while the other side of the left clamping sleeve is connected with the right clamping sleeve through a bolt pin. When the screw stud torque detecting tool is used, the left clamping sleeve and the right clamping sleeve are opened firstly and then directly clamp a screw stud which is limited by a positioning pin. Finally, a torque wrench is inserted into the square hole in order that detection can be performed. Therefore, the screw stud torque detecting tool has beneficial effects of fast and easy use, saving of labor, and high detecting efficiency of screw stud torque.
Description
Technical field
The utility model relates to a kind of testing tool, relates in particular to a kind of double-screw bolt moment of torsion testing tool.
Background technology
Arc stud welding is that metallic stud is welded on method on the workpiece, the method that realizes stud welding has multiple, as: arc pulling type arc stud welding, energy storage type arc stud welding, electric resistance welding, projection welding etc., all adopt arc stud welding in a lot of places of automotive field, for the reliability that guarantees that double-screw bolt connects, need carry out moment of torsion to double-screw bolt detects, because double-screw bolt itself can't be by the direct clamping of torque spanner, usually all be to overlap top nut at double-screw bolt, then nut is screwed to the bottom, torque spanner clamping nut detects, can also adopt thread bush to be enclosed within the outer end of double-screw bolt, thread bush one end opening, other end sealing, it is spacing that the outer end of double-screw bolt holds out against the blind end of thread bush like this, and torque spanner is connected the back and detects moment of torsion with thread bush then.Yet need be screwed into thread bush on the double-screw bolt when detecting moment of torsion, detecting well afterwards also needs to back-out comes, and loses time at every turn, and working strength is big, and detection efficiency is low.
Chinese patent Granted publication number: CN202547848U, November 21 2012 Granted publication day, a kind of aid that detects bolt torque is disclosed, comprise block and be used for sleeve with dial torque wrench assembling, block docks with sleeve openings, be provided with and the corresponding screw thread of detected bolt in block and the sleeve, block is the plane with the surface of contact of detected bolt end face.Use this kind aid, can the fast detecting moment of torsion big, and do not damage screw thread, and guaranteed the quality to equipment, prolonged the serviceable life of tooling device.Its weak point is need be screwed into aid on the double-screw bolt when detecting bolt torque at every turn, also needs to back-out after detecting and, and the process that is screwed into, back-outs is lost time, and operation intensity is big, and detection efficiency is low.
The utility model content
The utility model need to be screwed into, to back-out when double-screw bolt moment of torsion testing tool of the prior art uses in order to overcome, and uses inconvenience, loses time, the deficiency that detection efficiency is low, provide a kind of use fast, conveniently, very laborsaving, the double-screw bolt moment of torsion testing tool that double-screw bolt moment of torsion detection efficiency is high.
To achieve these goals, the utility model adopts following technical scheme:
A kind of double-screw bolt moment of torsion testing tool, comprise gripping sleeve, described gripping sleeve is cylindrical structure, the center of described gripping sleeve one end is provided with the circular hole that connects with the gripping sleeve bottom surface, be provided with screw thread in the described circular hole, the center of the described gripping sleeve other end is provided with square hole, described gripping sleeve comprise left clamp and with the right clamp of left clamp about diameter symmetry, one side of described left clamp is hinged with described right clamp, and the another side of described left clamp is connected with described right clamp latch.Double-screw bolt is fixed on the plate by arc stud welding, after when detecting moment of torsion left clamp and right clamp being opened, directly the end of double-screw bolt is reached the bottom of circular hole, then left clamp and right clamp are snapped together and link together by latch, at last the head of dial torque wrench is stretched in the square hole and detect moment of torsion and get final product, whole process is very convenient, with other testing tools comparisons, saved testing tool and rotated the time that is screwed into double-screw bolt, detection efficiency is more increased.
As preferably, the rectangle sides of described left clamp is provided with projection, described projection is provided with jack, the rectangle sides of described right clamp and the corresponding position of projection are provided with the cavity with the projection coupling, also be provided with pin-and-hole on the described right clamp, described pin-and-hole runs through cavity, is provided with register pin in the described pin-and-hole, and projection, cavity and register pin constitute described latch and connect.The projection of left side clamp inserts in the cavity, and register pin inserts in pin-and-hole and the jack then, and left clamp and right clamp are linked together reliably, and operation is very easy.
As preferably, described circular hole is shoulder hole, and the big end of described shoulder hole interior diameter is near the bottom surface of clamp.In the shoulder hole, diameter arranges different screw threads in the different hole, and such as the screw thread that M8, M10, M12 are set respectively in the shoulder hole, the moment of torsion that so just can be used for M8, M10, three kinds of different double-screw bolts of M12 detects highly versatile.
As preferably, all be provided with rounding on the hinged limit of left clamp and right clamp.When guaranteeing that left clamp and right clamp fit together, circular hole can cooperate closely with double-screw bolt, prevents that gripping sleeve from skidding, and therefore rounding is set, interfere between left side clamp and the right clamp when preventing hinged rotation and produce the gap, thereby prevent that gripping sleeve from skidding.
As preferably, the bottom of circular hole is provided with boss.Because in the time of the circular hole internal thread machining, the screw thread of circular hole bottom can not have screw thread because process less than, therefore boss is set, and prevents that the screw thread of the outer end of double-screw bolt when detecting moment of torsion from contacting with the circular hole bottom, thereby cause thread failure, influence the use of double-screw bolt.
Therefore, the utlity model has use fast, conveniently, very laborsaving, the beneficial effect that double-screw bolt moment of torsion detection efficiency is high.
