Abstract
The utility model relates to a pneumatic riveting machine tool which comprises a support and an L-shaped body frame. One supporting arm of the body frame is connected to one side of the upper surface of the support in a fastening mode, and the other supporting arm is parallel to the upper surface of the support. A block is connected to the support below the body frame in a fastening mode, and the upper surface of the block is parallel to the upper surface of the support. A through hole is formed in the supporting arm, above the block, of the body frame, and a supporting sleeve is connected in the through hole in a fastening mode. A connecting pipe is arranged in a supporting sleeve, a puncher pin is connected with the bottom end of the connecting pipe in a fastening mode, and a gas pressure cylinder is communicated with the top end of the connecting pipe in a fastening mode. The structural shape of the block and the puncher pin is defined according to the type of a riveting nut. The pneumatic riveting machine tool has the advantages of being centralized in acting force, stable in acting force direction, accurate in locating, stable and high in riveting strength, and can be widely used for riveting an automobile frame cross beam.
Description
Technical field
The utility model relates to a kind of riveting machine tool, particularly about a kind of for the Pneumatic rivet machine tool on frame crossbeam.
Background technology
The chassis frame of automobile is welded by crossbeam and longeron etc., on the crossbeam of vehicle frame, be useful on the nut that connects other parts, traditional mode that is fastenedly connected adopts welded nut, although this connected mode intensity is large, but in welding process, easily produce spatter, the defects such as welding deformation.Adopt riveting nut can meet intensity and instructions for use, can avoid again producing the defect such as spatter and welding deformation, but the equipment of traditional riveting nut still all can not meet Production requirement from using method production efficiency.
Summary of the invention
For the problems referred to above, the purpose of this utility model be to provide a kind of simple in structure, operating efficiency is high and good stability for the Pneumatic rivet machine tool on frame crossbeam.
For achieving the above object, the utility model is taked following technical scheme: a kind of Pneumatic rivet machine tool, it is characterized in that: it comprises a bearing, one L shaped body frame, one support arm of described body frame is fastenedly connected the side at described upper surface of support, and another support arm parallels with described upper surface of support; The described bearing of described body frame below tightens and connects a shape piece, and the upper surface of described shape piece parallels with described upper surface of support; On the support arm of the body frame of described shape piece top, offer a through hole, in described through hole, be fastenedly connected a support set; In described support set, be provided with a tube connector, the bottom of described tube connector is fastenedly connected a drift, fastening connection one gas pressure increasing cylinder in top.
The planform of described shape piece and drift is determined according to the type of riveting nut.
The utility model is owing to taking above technical scheme, and it has the following advantages: 1, because body frame of the present utility model adopts L shaped structure, therefore have advantages of that force localization, force direction are stable.2, adopt the structure of shape piece due to the utility model, therefore there is accurate positioning, stable and riveting intensity is high.3, provide riveting pressure because the utility model adopts gas pressure increasing cylinder, therefore have advantages of that force localization, active force are large.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present utility model
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model comprises a bearing 1, a body frame 2, a shape piece 3, a support set 4, a drift 5 and a gas pressure increasing cylinder 6.Wherein, body frame 2 adopts L shaped structure, and one support arm is connected to a side of bearing 1 upper surface by some bolted, and another support arm parallels with bearing 1 upper surface.Shape piece 3 is connected on the bearing 1 of body frame 2 belows by some bolted, and the upper surface of shape piece 3 parallels with bearing 1 upper surface.On the support arm of the body frame 2 of shape piece 3 tops, offer a through hole, support set 4 is fastenedly connected in this through hole.In support set 4, be provided with a tube connector 7, the bottom of tube connector 7 is fastenedly connected drift 5, the fastening connection gas pressure increasing cylinder 6 in top.Drift 5 moves up and down under the effect of gas pressure increasing cylinder 6, produces active force with shape piece 3, reaches the object of riveting nut.
In the above-described embodiments, the planform of shape piece 3 and drift 5 is determined according to the type of riveting nut.
While using the utility model, crossbeam is lifted on riveting machine tool, nut to be riveted is aimed at shape piece 3, starts riveting machine tool, and gas pressure increasing cylinder 6 increases pressure, drives drift 5 to move downward, and top, to nut one end, makes it crimp, is riveted on crossbeam.
The various embodiments described above are only for illustrating the utility model; wherein the structure of each parts, connected mode and manufacture craft etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
