Abstract
The utility model discloses a device for fixing a screw rod during screw rod tensile strength detection, which comprises two rectangular steel tubes (2) which are respectively connected with two ends of a screw rod (1), the two ends of the screw rod (1) respectively penetrate through one end surfaces of the two rectangular steel tubes (2), the two ends of the screw rod (1) are respectively arranged in the two rectangular steel tubes (2) which are internally provided with screw nuts (3) which are matched with the screw rod (1) in the size and the shape, and the screw nuts (3) are sheathed on the screw rod (1). In the device, by adopting the structure, the whole structure is simple and easy to realize; and the device can avoid the inaccuracy of tensile strength detection as the screw rod (1) is clamped during the screw rod tensile strength detection.
Description
Technical field
The utility model relates to the frock that detects screw rod tensile strength, specifically is the device of standing screw when being used for the detection of screw rod tensile strength.
Background technology
At present when detecting, the tensile strength to screw rod directly clamps screw rod by anchor clamps, the screw rod part that it is held when being stretched can be out of shape in stressed generation, screw rod is held part and is not held the part discontinuity, screw rod destructible, fracture, thus make testing result inaccurate.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of screw rod of avoiding to cause its tensile strength is detected the inaccurate device of standing screw when being used for screw rod tensile strength and detecting because of being held.
The purpose of this utility model is achieved through the following technical solutions: the device of standing screw when being used for the detection of screw rod tensile strength, comprise two steel quarter bends that are connected to the screw rod two ends, an end face of two steel quarter bends is passed at the two ends of described screw rod respectively, and the screw rod two ends lay respectively in two steel quarter bends, be provided with the nut with screw rod size, form fit in the described steel quarter bend, described nut sleeve is located on the screw rod.
Be provided with the pad that is set on the screw rod between described nut and the steel quarter bend.
Described steel quarter bend is connected with steel plate with respect to the other end of passing the screw rod end face.
Principle of work of the present utility model: the utility model is fixed the two ends of screw rod by steel quarter bend and nut, and before the tensile strength to screw rod detected, anchor clamps clamped the steel plate that is connected with the steel quarter bend, detects thereby can carry out tensile strength to screw rod.
The utility model compared with prior art has the following advantages and beneficial effect: the utility model comprises steel quarter bend, steel plate and nut, one-piece construction is simple, be convenient to realize, and when the tensile strength to screw rod detects, anchor clamps are clamped on the steel quarter bend of the present utility model, thereby can avoid causing screw rod to be held the position stress deformation on the screw rod making testing result inaccurate because of anchor clamps are clamped in.
Description of drawings
Structural representation when Fig. 1 is the utility model standing screw.
The pairing name of Reference numeral is called in the accompanying drawing: 1, screw rod, 2, the steel quarter bend, 3, nut, 4, pad, 5, steel plate.
Embodiment
The utility model is described in further detail below in conjunction with embodiment, but embodiment of the present utility model is not limited thereto.
Embodiment:
As shown in Figure 1, the utility model comprises two steel quarter bends 2 and two nuts 3, an end face of steel quarter bend 2 is provided with the perforation with screw rod 1 size, form fit, as preferably, the aperture of perforation is used for the big 1.5mm of diameter of the screw rod 1 of tested tensile strength, the perforation of two steel quarter bends 2 is passed at the two ends of screw rod 1 respectively, and the two ends of screw rod 1 lay respectively in two steel quarter bends 2.Size, the form fit of nut 3 and screw rod 1, two nuts 3 are set in the two ends of screw rod 1 respectively and lay respectively in two steel quarter bends 2, nut 3 makes the structure between screw rod 1 and the steel quarter bend 2 more stable, when avoiding screw rod 1 detected between screw rod 1 and the steel quarter bend 2 syndeton come off.
Be provided with the pad 4 that is set on the screw rod 1 between nut 3 of the present utility model and the steel quarter bend 2, pad 4 can be made by rubber, and it is used to prevent the rigid friction between nut 3 and the steel quarter bend 2.The utility model steel quarter bend 2 is connected with steel plate 5 with respect to the other end of passing screw rod 1 end face, the quantity of steel plate 5 is two, and be connected on two steel quarter bends 2, steel plate 5 is used for when the tensile strength to screw rod 1 detects the hold assembly as anchor clamps.
As mentioned above, then can well realize the utility model.
Claims (3)
1. the device of standing screw when being used for the detection of screw rod tensile strength, it is characterized in that: comprise two steel quarter bends (2) that are connected to screw rod (1) two ends, an end face of two steel quarter bends (2) is passed at the two ends of described screw rod (1) respectively, and screw rod (1) two ends lay respectively in two steel quarter bends (2), be provided with nut (3) big or small with screw rod (1), form fit in the described steel quarter bend (2), described nut (3) is set on the screw rod (1).
