The specific embodiment
For object, technical scheme and advantage that the utility model is implemented are clearer, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is further described in more detail.In the accompanying drawings, same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Described embodiment is the utility model part embodiment, rather than whole embodiment.Be exemplary below by the embodiment being described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
In description of the present utility model, it will be appreciated that, term " " center ", " longitudinally ", " laterally ", " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", orientation or the position relationship of indications such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, rather than device or the element of indication or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as the restriction to the utility model protection domain.
Fig. 1 is according to the schematic diagram of the main beating cap mounting tool of the utility model one embodiment.Fig. 2 is the schematic diagram of the support of the mounting tool of main beating cap shown in Fig. 1.Fig. 3 is the schematic top plan view of the support of the mounting tool of main beating cap shown in Fig. 1.Fig. 4 is the schematic diagram of the pin of the mounting tool of main beating cap shown in Fig. 1.
Referring to Fig. 1, main beating cap mounting tool comprises: (the first alignment pin is identical with the second locating pin structure in the illustrated embodiment for support 3, the first alignment pin and the second alignment pin, only mark alignment pin 4, but the first alignment pin also can be different from size and the structure of the second alignment pin, its concrete structure is determined according to actual needs).
The upper end of alignment pin 4 has screwed hole 43, can be threaded connection part and stop alignment pin 4 from top to bottom to deviate from alignment pin installing hole 34, and alignment pin upper end has the platform that stops that stops alignment pin 4 from bottom to top to deviate from alignment pin installing hole 34.It is pointed out that alignment pin 4 is not limited to by the installation method shown in figure is installed on support 3, and the installation method that also can meet instructions for use by other is installed, for example riveted joint etc.
Advantageously, alignment pin 4 stretches out the summation that support 3 length are less than the degree of depth of installing hole of main beating cap and the degree of depth of the installing hole of main bearing seat, and support 3 is contacted with main beating cap, directly beats support 3 main beating cap is installed on main bearing seat.
Referring to Fig. 2, support 3 has handle 33, and handle 33 is connected with described rack body, and the bearing of trend of handle 33 is contrary with the bearing of trend of alignment pin 4, and the central axis of handle 33 is parallel with the central axis of alignment pin 4, two alignment pins 4 are about the central axis symmetry of handle 33.In the time that main beating cap is installed, beat handle 33, avoid directly beaing the unbalance stress phenomenon that main beating cap produces.
The upper end of handle 33 has threaded rod 31, and the mode that handle cover 1 is threaded connection is installed to threaded rod 31 places, is convenient to beaing in the use procedure of described main beating cap mounting tool.
Referring to Fig. 1, the outside of handle 33 further has taper knob 2, and the material of taper knob 2 can be the comparatively light and lower-cost material such as plastics, rubber.Taper knob 2 is socketed in the outside of handle 33, stops taper knob 2 to deviate from handle 3 by handle cover 1, when taper knob 2 increases the hand-held diameter of handle to the not larger change of the quality of support 3, and the material such as plastics, rubber make hand-held more comfortable.
On described rack body, there is the breach of the main beating cap dodged, avoid being stamped at base bearing the normal use that affects described main beating cap mounting tool protruding in the situation that.Described breach is preferably arc notch, makes described main beating cap mounting tool better and main beating cap is used in conjunction with.
Referring to Fig. 1, the bottom of described rack body is set to supporting leg form, saves the manufactured materials of support in meeting applicable requirements, reduces manufacturing cost.
Advantageously, alignment pin 4 is hierarchic structure, front rank 41 are positioned at one end that alignment pin 4 is connected with described rack body, front rank 41 are matched in clearance with the installing hole of main beating cap, the length that described rack body is stretched out on front rank 41 be greater than main beating cap installing hole the degree of depth and do not contact with the screwed hole of the installing hole of main bearing seat, rear rank 42 are suitable for inserting in the mode of matched in clearance the screwed hole of the installing hole of main bearing seat.
Because the diameter of the installing hole of main beating cap and the screwed hole of main bearing seat is different, the location that alignment pin 4 is set to hierarchic structure and can better completes main beating cap, reduces the gap between alignment pin and the installing hole of main beating cap.
Between 0.2mm to 1mm, (described gap width is bilateral gap sum in gap between front rank 41 and the installing hole of main beating cap, be diameter poor in axle and hole), gap between the screw thread of the installing hole of rear rank 42 and main bearing seat is (described gap is bilateral gap sum, and the diameter in axle and hole is poor) between 0.2mm to 1mm.
Advantageously, the more preferably 0.4mm of gap between front rank and the installing hole of main beating cap, the more preferably 0.4mm of gap between the screw thread of the installing hole of rear rank 42 and main bearing seat.
The quantity that it is pointed out that the alignment pin of above-mentioned frock is not limited to two, also can be set to three, four etc.
Above-mentioned main beating cap mounting tool is simple in structure, easy to use, can effectively improve accuracy and the installation effectiveness of main beating cap location.
In use, staff only need insert alignment pin to beat handle cover after the installing hole of main beating cap and the installing hole of main bearing seat and can complete installation, realize aligning of main beating cap installing hole and main bearing seat installing hole by the location of main beating cap mounting tool, avoid the appearance of fictitious force square, and then improve the safety and reliability of engine.
Finally it is to be noted: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit.Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of the each embodiment technical scheme of the utility model.
