Abstract
The utility model discloses a motorcycle test fixture mounting structure, which comprises a horizontal iron-cast platform and a clamp bottom plate. The horizontal iron-cast platform is provided with a T-shaped groove. The width of the cross section of the lower part of the T-shaped groove is greater than the width of the cross section of the upper opening part of the T-shaped groove. The clamp bottom plate is provided with a bolt hole. The motorcycle test fixture mounting structure is characterized in that an anchor nut positioned corresponding to the bolt hole of the clamp bottom plate is arranged in the T-shaped groove. The distance between opposite sites of the anchor nut is smaller than the width of the cross section of the lower part of the T-shaped groove and is greater than the width of the cross section of the upper opening part of the T-shaped groove. The diagonal distance of the anchor nut is greater than the width of the cross section of the lower part of the T-shaped groove. A fastening bolt is arranged in the bolt hole of the clamp bottom plate. The front end of the fastening bolt extends downwards into the T-shaped groove and is tightly connected with the anchor nut. Compared with the prior art, the motorcycle test fixture mounting structure can conveniently adjust the position of a clamp and re-position the clamp, and also has the advantages of simple structure, high working efficiency, low labor intensity and good fastening effect.
Description
Technical field
The utility model relates to a kind of motorcycle engine and car load fixation test anchor clamps, especially a kind of mounting structure of motorcycle test fixture is installed.
Background technology
Motorcycle need to be made motorcycle engine and car load fixation test are installed when producing, and during test test fixture is fixed on the ground black iron, then at test fixture motorcycle is installed and is tested.
The mounting structure of existing motorcycle test fixture, at the ground black iron T-shaped groove to be set, T-shaped groove lower section width is greater than upper opening place cross-sectional width, then in T-shaped groove, foot bolt is set, adopts fastening nuts to connect after the foot bolt front end upwards passes T-shaped groove upper opening and passes bolt hole on the clamp bottom board.Because when motorcycle is tested, carrying out with experimental procedure, need to reorientate anchor clamps, like this, when reorientating sectional fixture, need to lift anchor clamps together with engine, just can wear foot bolt, and anchor clamps and engine are all heavier, very inconvenience have reduced work efficiency so seem.Side by side foot bolt is installed when fastening, and head causes anchor clamps loosening easily from T-shaped track landing.
The utility model content
For above-mentioned deficiency, technical problem to be solved in the utility model is: how to provide a kind of simple in structure, conveniently anchor clamps are adjusted and reorientated, increase work efficiency, improve simultaneously the motorcycle test fixture mounting structure of fastening effect.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model.
A kind of motorcycle test fixture mounting structure, comprise ground black iron and clamp bottom board, has T-shaped groove on the described ground black iron, T-shaped groove lower section width is greater than upper opening place cross-sectional width, has bolt hole on the described clamp bottom board, it is characterized in that, place, corresponding anchor clamps bed bolt hole is provided with anchor nut in the described T-shaped groove, the anchor nut opposite side distance is from less than T-shaped groove lower section width but greater than T-shaped groove upper opening place cross-sectional width, the anchor nut diagonal distance is greater than T-shaped groove lower section width, be provided with fastening bolt in the described clamp bottom board bolt hole, the fastening bolt front end stretches into T-shaped groove downwards and is fastenedly connected with anchor nut.
Motorcycle test fixture mounting structure of the present utility model when anchor clamps need to be readjusted, only need be outwarded winding fastening bolt and take away, then directly moves horizontally anchor clamps and carries out the position adjustment, and anchor nut is stayed in the T-shaped groove at former place.After adjusting chucking position, adopting long rod to stretch into from the end of the T-shaped groove at former lower margin nut place releases anchor nut, then anchor nut is put into the T-shaped groove corresponding to bolt hole of anchor clamps adjusted position postpone, adopt long rod to promote anchor nut to clamp bottom board bolt hole corresponding position, fastening bolt is again penetrated in the T-shaped groove and enters in the corresponding anchor nut from the clamp bottom board bolt hole, the rotation fastening bolt, because the anchor nut diagonal distance is greater than T-shaped groove lower section width, so anchor nut is blocked and can not rotate by T-shaped groove bottom during the rotation fastening bolt, anchor nut can only be forced upwardly motion, along with screw thread screws darker, anchor nut is also slowly raised up the both sides at the upper opening place that is attached to tightly T-shaped groove, has realized the tight joint of anchor clamps with the ground black iron.Like this, when readjusting chucking position, the whole process of reorientating all need not anchor clamps are lifted, and only need move horizontally anchor clamps and get final product, so, greatly reduce labour intensity, increase work efficiency.Simultaneously, in this mounting structure, because nut is positioned at the below, the weight ratio bolt weight of nut is lighter, thus more be difficult for falling down, so improved fastening effect.
As optimization, the screw thread specification of described anchor nut and fastening bolt is M16.After optimizing like this, adopt the screw thread of this specification, more can improve fastening effect.
As further optimization, described anchor nut upper end has an extension that extends up in the T-shaped channel opening place, and described extension height is less than the degree of depth at T-shaped channel opening place.After optimizing like this, being connected between convenient fastening bolt and the anchor nut.
In sum, than prior art, the utility model can conveniently be adjusted and reorientate anchor clamps, have simple in structure, high efficiency, labour intensity is low, fastening effective advantage.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
During implementation, as shown in Figure 1, a kind of motorcycle test fixture mounting structure, comprise ground black iron 1 and clamp bottom board 2, has T-shaped groove 3 on the described ground black iron 1, T-shaped groove 3 lower section width are greater than upper opening place cross-sectional width, has bolt hole on the described clamp bottom board 2, wherein, described T-shaped groove 3 interior corresponding clamp bottom boards 2 bolt hole places are provided with anchor nut 4, anchor nut 4 opposite side distance are from less than T-shaped groove 3 lower section width but greater than T-shaped groove upper opening place cross-sectional width, anchor nut 4 diagonal distance are greater than T-shaped groove 3 lower section width, be provided with fastening bolt 5 in the bolt hole of described clamp bottom board 2, fastening bolt 5 front ends stretch into T-shaped groove 3 downwards and are fastenedly connected with anchor nut 4.Wherein, the screw thread specification of described anchor nut 4 and fastening bolt 5 is M16.Wherein, described anchor nut 4 upper ends have an extension that extends up in the T-shaped channel opening place, and described extension height is less than the degree of depth of T-shaped groove 3 opening parts.
