Abstract
The utility model provides a kind of engine mounting bracket structure, comprise rack body, described rack body is provided with bolt installation base, and described bolt installation base is the boss of grading press drawing and forming, described bolt installation base top is provided with a high hole flanging, and described high hole flanging projection welding has a nut.The utility model adopts project-welding nut mode, not only the screw strength of nut itself can ensure completely, and weld strength also can be guaranteed by adjusting, monitor welding parameter, thereby guarantees that the size of part and performance meet design and matching requirements, reduce the application risk of car load.In addition, forming parts technique is simple, less demanding to the internal diameter size of high hole flanging, and mould complexity and cost also reduce greatly.
Description
Technical field
The utility model relates to Automobile manufacturing, relates in particular to a kind of engine mounting bracket structure.
Background technology
Engine bed is the key components and parts in vehicle structure, and vibration and antagonistic force that it need to carry driving engine self on the one hand, also will bear the load that various road surfaces situation is come by vehicle frame transmission on the other hand.Simultaneously, it also has driving engine and transmission assembly is arranged on to the effect on body support, therefore not only require engine mounting bracket to there is bearing function, also require to have bolt installation function, think and ensure the function of engine mounting bracket, need correct, strict its size of control and performance.
In prior art, two tapped bore installing for bolt on rack body form through multi-drawing.And in actual production process, cannot accomplish to overlap completely in each location that stretches, part may form ellipse completing stretching rear thread bottom outlet.And in general, the easy too high internal diameter size that causes of the part of multi-drawing drift temperature in drawing process is bigger than normal, and easily occurs necking phenomenon.Internal diameter size meeting bigger than normal causes thread size bigger than normal, thereby causes the sliding tooth of hold-down bolt, and driving engine cannot be installed or come off, and finally causes serious potential safety hazard and accident.Can cause effective thread quantity not sufficient if there is necking phenomenon, also can cause the sliding tooth of hold-down bolt, and then cause safety misadventure.
Utility model content
Technical problem to be solved in the utility model is exactly for above shortcomings in prior art, provides a kind of engine mounting bracket structure, for solving the problems of the prior art.
For achieving the above object and other relevant objects, the utility model provides a kind of engine mounting bracket structure, comprise rack body, described rack body is provided with bolt installation base, described bolt installation base is the boss of grading press drawing and forming, described bolt installation base top is provided with a high hole flanging, and described high hole flanging projection welding has a nut.
Further, the stretching of described bolt installation base is highly 40.3mm.
Further, the internal diameter of described high hole flanging is φ 32.3mm.
Further, described nut is M10 nut.
By above technical scheme, the utility model has following technique effect compared to prior art: the utility model adopts project-welding nut mode, not only the screw strength of nut itself can ensure completely, and weld strength also can be guaranteed by adjusting, monitor welding parameter, thereby guarantee that the size of part and performance meet design and matching requirements, reduce the application risk of car load.In addition, forming parts technique is simple, less demanding to the internal diameter size of high hole flanging, and mould complexity and cost also reduce greatly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view of Fig. 1.
Element numbers explanation:
1 rack body
2 bolt installation bases
3 nuts
Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this specification sheets.
Refer to Fig. 1 to Fig. 2.Notice, appended graphic the illustrated structure of this specification sheets, ratio, size etc., all contents in order to coordinate specification sheets to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this specification sheets, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
Based on improving engine mounting bracket structure design, the object requiring to meet dimensional characteristic, performance requriements and the car load usability of part, reaches the stability of avoiding defective part, reducing production costs, improve part quality.The utility model provides a kind of engine mounting bracket structure, consult shown in Fig. 1, comprise rack body 1, described rack body 1 is provided with bolt installation base 2, described bolt installation base 2 is the boss of grading press drawing and forming, described bolt installation base top is provided with a high hole flanging, and described high hole flanging projection welding has a nut 3 (shown in Fig. 2), and nut 3 is preferably M10 nut.
As further improvement of the utility model: in the case of the stretching of bolt installation base highly keep 40.3mm constant, the hole internal diameter of the high hole flanging of part is defined as Φ 32.3mm, part drawing coefficient of the present utility model (diameter ratio before the diameter after stretching and stretching) is reduced greatly, and the moulding difficulty of part can reduce greatly.
Be described in further detail below in conjunction with specific process of the present utility model:
1) grading press manufacturing procedure:
------stretching (five processes),---------deburring (three process)---flange---separates in punching in moulding in deburring (two procedures) in punching;
Grading press part totally 15 procedures, 4 order rooms, are used the grading press of 1250T.
2) subsequent handling:
Projection welding M10 nut.
In sum, the utility model adopts project-welding nut mode, not only the screw strength of nut itself can ensure completely, and weld strength also can be guaranteed by adjusting, monitor welding parameter, thereby guarantee that the size of part and performance meet design and matching requirements, reduce the application risk of car load.In addition, forming parts technique is simple, less demanding to the internal diameter size of high hole flanging, and mould complexity and cost also reduce greatly.So the utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under such as and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
