Abstract
The utility model provides a positioning shaft dismounting device which comprises a support body for fixing the whole device, a screw rod, a nut and a handle, wherein an external thread section matched with the nut is arranged at one end of the screw rod, a via hole allowing the handle to pass is formed in the other end of the screw rod; and a via hole which can allow the screw rod to pass but prevents the nut from passing is formed in the support body. With the adoption of the positioning shaft dismounting device, a positioning shaft can be rapidly and conveniently dismounted when clamped, the structure is simple, and the operation is easy.
Description
Technical field
The utility model relates to mechanical field, and it is specifically related to a kind of locating shaft provision for disengagement.
Background technology
Locating shaft in the welding positioning tool, after the workpiece welding, due to the distortion of part, often causes locating shaft to be pinned and is difficult to dismounting, and because the restriction of operating space is difficult to locating shaft is pounded out.
The utility model content
The purpose of this utility model is to solve the problem that prior art exists, and a kind of locating shaft provision for disengagement is provided, when being pinned, locating shaft can quickly and easily it be disassembled, and simple in structure, easy operating.
In order to reach above-mentioned technical purpose, the utility model by the following technical solutions:
A kind of locating shaft provision for disengagement, comprise supporter, screw rod, nut and handle that whole device is fixed, one end of described screw rod is provided with the external thread section matched with described nut, the other end is provided with the via hole that can make handle pass, and described supporter is provided with and can passes but prevent the via hole that described nut passes for described screw rod.
As such scheme preferably, the center superposition of the center of via hole and described supporter on described supporter.
As such scheme preferably, on described screw rod on the axis that is centered close to described screw rod of via hole.
Owing to having said structure, the utility model has the following advantages compared to existing technology: the utility model provides a kind of locating shaft provision for disengagement, when being pinned, locating shaft can quickly and easily it be disassembled, and simple in structure, easy operating.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation that Fig. 1 is the utility model embodiment;
The structural representation of the supporter that Fig. 2 is the utility model embodiment;
The structural representation of the screw rod that Fig. 3 is the utility model embodiment;
The structural representation of the actual use that Fig. 4 is the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
As Figure 1-3, the utility model provides a kind of locating shaft provision for disengagement, comprise the supporter 1 that whole device is fixed, screw rod 2, nut 3 and handle 4, one end of described screw rod 2 is provided with external thread section 21, the other end is provided with the via hole 22 that can make handle pass, described supporter 1 is provided with and can passes but prevent the via hole 11 that described nut passes for described screw rod, described nut 3 matches with the external thread section 21 of screw rod 2, the center superposition of via hole 11De center and described supporter 1 on described supporter, on described screw rod on the axis that is centered close to described screw rod 2 of via hole 22.
A kind of locating shaft provision for disengagement is provided, can quickly and easily it be disassembled when locating shaft is pinned, and simple in structure, easy operating.
The actual use schematic diagram of a kind of locating shaft provision for disengagement that Fig. 4 provides for the utility model, during use, supporter 1 is fixed on locating shaft mount pad 6 by bolt 5, nut 3 is inserted on the external thread section 21 of screw rod 2, again external thread section 21 is matched with the internal thread of locating shaft 7 through via hole on supporter 11 is rear, now, screw rod 2 passes through the screw thread secure fit with locating shaft 7, nut 3 is positioned at the supporter outside near supporter 1, the via hole 22 again handle 4 passed on screw rod 2, controlling the handle 4 of stopping in the time of dextrorotation turn nut 3 does not allow handle rotate, due to nut 3 and screw rod 2 threaded engagement, screw rod 2 and locating shaft 7 screw thread secure fit, rotating nut 3 can make nut 3 advance originally, but because having hindered it, supporter 1 advances, therefore can produce a power that forces screw rod 2 to retreat, thereby screw rod 2 retreats to drive locating shaft 7 is extracted from welding work pieces 8.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
