Abstract
The utility model discloses a stud torque detecting sleeve which comprises a sleeve body matched with a torque wrench and further comprises a magnetized nut block. The nut block is detachably connected with the sleeve body. A threaded hole matched with a welding stud to be detected is formed in an end face of the nut block. The nut block can be reliably connected to the sleeve body. Meanwhile, the nut block is connected with the welding stud to be detected in a screwed mode. The welding stud to be detected and the sleeve body keep relative positions fixed in the single direction and the circumferential direction and then the sleeve body is installed on the torque wrench. The torque wrench is continuously rotated in the screwing direction so as to produce torque and carry out detection on the torque of the stud. Detecting accuracy and detecting efficiency can be improved with the stud torque detecting sleeve.
Description
Technical field
The utility model relates to a kind of automobile component testing tool, and in particular, it relates to a kind of double-screw bolt torsion and detects sleeve.
Background technology
In Automobile Welding technique, often double-screw bolt need to be welded on the vehicle body steel plate with stud welding machine, be used for assembling, the fixing part on the vehicle body.Because the intensity to stud welding has technological requirement, therefore, in welding process, need the part after the welding is carried out strength test, usually use torque wrench that the double-screw bolt after welding is beaten moment of torsion and inspect by random samples.Because double-screw bolt does not have corner angle, general square hole or Hexagonal jacket can't entangle double-screw bolt and tighten to twist beats moment of torsion, and conventional method is that nut is screwed on the double-screw bolt, and nut is screwed to the double-screw bolt bottom and then is wrenched nut with torque spanner, until torque spanner reaches the upper limit.General double-screw bolt length is 15 ~ 25mm, and the degree of depth of ordinary cartridge socket is more shallow, sleeve tends to interfere and press not on earth with double-screw bolt, often will screw on 2 ~ 3 plain nuts ability bed hedgehoppings to entangling with sleeve for this reason, can beat moment of torsion with spanner, therefore operate and to do more preparation, can't reach fast detecting.Publication number is that the utility model of CN201783895U discloses a kind of Multi-functional socket wrench for the check stud welding intensity on April 6th, 2011, uses the problem that multiple testing tool and part are scrapped when checking stud welding intensity to solve.This Multi-functional socket spanner for testing stud welding strength comprises the sleeve of both ends of the surface perforate, and external peripheral surface is provided with limited block at the two ends of sleeve, and the end face of the relative sleeve of limited block slopes inwardly.During use, this Multi-functional socket spanner for testing stud welding strength need not be prepared any nut, torque spanner or other instruments of inspections, only need to be with jacket casing on welding screw, about pull 15 the degree, then test, afterwards double-screw bolt is turned back original position, get final product with the CO2 repair welding, needn't faulty part, the utility model can be checked the double-screw bolt of M6 and two kinds of specifications of M8 in addition.The utility model has the advantages that simple in structure, practicality is strong and needn't faulty part.But the measurement result that can't obtain quantizing when measuring with this utility model, and larger to the destructiveness of tested object.
The utility model content
Not good in order to overcome existing stud welding handle intensity detection tool and welding screw to be measured coupling, preparation is than time-consuming, affect the defective of detection efficiency and accuracy, the utility model provides a kind of and can be connected with welding screw to be measured is fast and reliable, and the double-screw bolt torsion that improves detection efficiency and accuracy detects sleeve.
The technical solution of the utility model is: a kind of double-screw bolt torsion detects sleeve, comprises the sleeve supporting with torque spanner, also comprises magnetized nut block, and nut block and sleeve removably connect, and the nut block end face is provided with the screwed hole with welding screw coupling to be measured.Nut block can be connected on the sleeve reliably, nut block can screw with welding screw to be measured again and be connected simultaneously, keep unidirectional circumferential relative position to fix between welding screw to be measured and sleeve, then sleeve is installed on the torque spanner, continue just can to beat moment of torsion towards the direction twisting that screws and carry out the detection of double-screw bolt torsion.
As preferably, sleeve is provided with the square sleeve interface, and nut block is four-prism, adaptive and slotting being embedded in the square sleeve interface of nut block and square sleeve interface.Square is common socket shape on the existing sleeve, and the nut block of four-prism shape can be mated with sleeve well, and four-prism processing is comparatively easy.
As an alternative, sleeve is provided with the regular hexagon socket, and nut block is positive hexagonal prism, adaptive and slotting being embedded in the regular hexagon socket of nut block and regular hexagon socket.Regular hexagon also is a kind of common socket shape on the sleeve, if with the sleeve of regular hexagon mouth, nut block is also wanted the corresponding hexagonal prism that is processed into.
As preferably, screwed hole is blind hole.Blind hole depth is less, and double-screw bolt can be screwed into the end quickly when nut block was connected with welding screw to be measured, can begin quickly to detect, and shortens sense cycle.
The beneficial effects of the utility model are:
Conveniently reliably dock with welding screw to be measured, improve detection accuracy.Between nut block and welding screw to be measured and sleeve adaptive interface is arranged all in the utility model, by the connection of nut block, sleeve can stably to welding screw transmitting torque to be measured, accurately detect stud welding intensity.
Improve detection efficiency.By the connection of nut block, sleeve can reliably dock with the welding screw of all lengths, is not required to be the length that adapts to welding screw and takes the alternate manner bed hedgehopping, need not to increase too much preparation, thereby can greatly improve detection efficiency.

Fig. 2 is a kind of structural representation of the present utility model.
Among the figure, 1-sleeve, 2-nut block, 3-screwed hole, 4-square sleeve interface.
The specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawing specific embodiment.
Embodiment 1:
As shown in Figure 1, a kind of double-screw bolt torsion detects sleeve, comprises the sleeve 1 supporting with torque spanner, also comprises magnetized nut block 2, and nut block 2 is detachable with sleeve 1, and nut block 2 end faces are provided with the screwed hole 3 with double-screw bolt coupling to be measured, and screwed hole 3 is blind hole.Sleeve 1 is provided with square sleeve interface 4, and square sleeve interface 4 inwalls are provided with card bead embedding hole, and nut block 2 is four-prism, and nut block 2 is provided with card bead, nut block 2 and adaptive and slotting being embedded in the square sleeve interface of square sleeve interface.
Embodiment 2:
As shown in Figure 2, sleeve 1 is provided with the regular hexagon socket, and nut block 2 is positive hexagonal prism, nut block 2 and adaptive and slotting being embedded in the regular hexagon socket of regular hexagon socket.All the other are with embodiment 1.
