Description
Technical Field
The utility model relates to an examine utensil, especially a torque detection tool.
Background
Before the product leaves the factory, parameters such as the size, the precision and even the binding force of each part of the product need to be detected, and the product can leave the factory after the detection is qualified. The surface of some workpieces needs to be welded with a nut for connecting other components, so that whether the bonding force between the nut and the workpiece meets the bearing requirement or not is a parameter needing to be detected. Traditionally, an operator pulls a target nut with a wrench, and observes a torque meter arranged on the wrench at any time, and the reading on the torque meter is the maximum torque which can be borne by the nut when the nut is loosened. In the detection process, the torque born by the nut is the torque of the wrench, the torque is the product of the moment arm and the force, and during actual operation, the position held by an operator can have tiny difference every time, the applied force is difficult to be quantized uniformly, so that the traditional manual detection mode has errors, and further the quality of a product is influenced. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed, can be fast, convenient and measure the detection tool of the maximum torque that the nut can bear of being surveyed accurately.
The technical solution of the utility model is that: a torque detection tool which characterized in that: the jig comprises a bottom plate 1, a torque output mechanism 2 is arranged in the middle of the bottom plate 1, workpiece supports 3 are arranged on two sides of the torque output mechanism 2, the two workpiece supports 3 are symmetrically distributed, a fixing groove 4 is arranged on each workpiece support 3,
the torque output mechanism 2 comprises two support blocks 5 which are symmetrically distributed, a lead screw 6 is jointly rotatably supported between the two support blocks 5, a hand wheel 7 is arranged at the end part of the lead screw 6, a nut block 8 is also connected on the lead screw 6 in a matching way, the nut block 8 is positioned between the two support blocks 5, a rotating body 9 is rotatably supported on the top end surface of the nut block 8, a groove 10 which is horizontally distributed is arranged on the rotating body 9,
the jig further comprises a wrench 11, an end head of the wrench 11 is provided with a hexagon socket, the wrench 11 is matched with the groove 10, and the wrench 11 is further provided with a torque meter 12.
Compared with the prior art, the utility model, have following advantage:
the torque detection jig with the structure is simple in structure, ingenious in design and reasonable in layout, and aims at the problems existing in the traditional torque detection mode, a special structure is designed, firstly, the torque arm of the torque applied to the tested nut can be strictly limited, and meanwhile, accurate displacement is realized through the transmission pair of the screw rod and the nut, so that the force of the torque applied to the tested nut is limited, namely, the torque can be accurately applied to the tested nut, an accurate measurement result is obtained, and the quality problem caused by measurement errors is avoided. The detection jig has the advantages of simple manufacturing process and low manufacturing cost, is particularly suitable for popularization and application in the field, and has wide market prospect.
