Abstract
The invention discloses a welding tool of jinny connection plates of a marine crane and relates to the technical field of marine crane manufacturing. The welding tool comprises two templates, wherein positioning sleeves having the same distance and provided with center holes are arranged on the two templates respectively, at least one positioning mandrel penetrates through the center holes of the corresponding positioning sleeves of the two templates, and two positioning columns are arranged on the positioning mandrel; the two templates are provided with positioning pins which penetrate through the center holes of the positioning sleeves and through holes of the connection plates sequentially and are provided with positioning tables. Compared with the prior art, the welding tool can solve the problems that existing welding of the connection plates cannot guarantee the accuracy requirement of coaxiality of the through holes and the rework efficiency is high.
Description
Technical field
The present invention relates to loop wheel machine manufacturing technology field peculiar to vessel, especially a kind of frock for welding loop wheel machine jinny connecting plate peculiar to vessel.
Background technology
The jinny of loop wheel machine peculiar to vessel has cylindrical shell and is welded on two upper and lower two pieces of connecting plates on this cylindrical shell, at present, in loop wheel machine manufacturing peculiar to vessel, the upper and lower two piece connecting plates fixing to winch weld, and usually only use a plug and spacer to position two pieces of connecting plates and weld.There are the following problems in process of production for this welding method: welding can only ensure the pitch requirements between upper and lower two pieces of connecting plates like this, and the required precision of through hole axiality on the connecting plate that can not ensure hole on the connecting plate of top and below, frequent needs are done over again, rework rate is high, adds production cost.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of loop wheel machine jinny connecting plate welding tooling peculiar to vessel, can not ensure the required precision of through hole axiality and the high problem of rework rate with the welding solving existing connecting plate.
The technical scheme that technical solution problem of the present invention adopts is: a kind of loop wheel machine jinny connecting plate welding tooling peculiar to vessel includes two pieces of templates, two pieces of described templates are equipped with the positioning sleeve being provided with centre bore that spacing is equal, the centre bore of two pieces of corresponding positioning sleeves of described template is at least coated with a positioning core axle, institute's rheme axle is provided with two locating dowels; Two pieces of described templates are equipped with the alignment pin being provided with positioning table passing described positioning sleeve centre bore and described connecting plate through hole successively.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: 1, because the distance between two pieces of connecting plates is located by positioning core axle, the axiality of two pieces of corresponding through holes of connecting plate is by template, locating core and alignment pin location, therefore, the axiality requirement of through hole on the connecting plate that can ensure hole on the connecting plate of top and below after welding, do not need to do over again, namely ensure welding quality, again reduce production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Two pieces of connecting plates 1 set up and down that loop wheel machine jinny peculiar to vessel as shown in Figure 1 includes cylindrical shell 6 and is welded on this cylindrical shell 6, every block connecting plate 1 is all evenly distributed with multiple through hole being provided with projection, top connecting plate 1 is all arranged in coaxial with the multiple through holes on below connecting plate 1.
Loop wheel machine jinny connecting plate welding tooling peculiar to vessel is as shown in Figure 1 used to be welded on cylindrical shell by two pieces of connecting plates 1, this loop wheel machine jinny connecting plate welding tooling peculiar to vessel includes two pieces of templates 2, two pieces of templates 2 are all welded with the positioning sleeve 3 being provided with centre bore that multiple spacing is equal with the through-hole spacing of connecting plate 1, the present embodiment is coated with two positioning core axles 4 on the centre bore of two pieces of corresponding positioning sleeves 3 of template 2, axle 4 in place is provided with two locating dowels, locating dowel 4-1 and locating dowel 4-2; Two pieces of templates 2 are all movably equipped with the alignment pin 5 being provided with positioning table passing positioning sleeve 3 centre bore and connecting plate 1 through hole successively.
During work, A, one piece of connecting plate 1 is welded on position that cylindrical shell 6 sets; B, one piece of template 2 to be placed on connecting plate 1, to make positioning sleeve 3 be buckled in the projection of connecting plate 1 through hole, two positioning core axles 4 are inserted on two through holes of connecting plate 1 respectively, the end face of one of them locating dowel 4-2 and positioning sleeve 3 upper surface are abutted against; Again an alignment pin 5 is inserted into a through hole of connecting plate 1 by the centre bore of positioning sleeve 3, the positioning table end face of alignment pin 5 and positioning sleeve 3 upper surface are abutted against; C, the connecting plate 1 second piece being placed with template 2 are installed on two positioning core axles 4 by two through hole respectively, the lower surface of another locating dowel 4-2 of two positioning core axles 4 and another block connecting plate 1 of top is abutted against, an alignment pin 5 is inserted in a through hole of connecting plate 1 by the centre bore of positioning sleeve 3, the positioning table end face of alignment pin 5 and positioning sleeve 3 upper surface are abutted against, respectively by nut, connecting plate 1 is fixed on positioning core axle 4; D, second piece of connecting plate 1 to be connected with cylindrical shell 6 spot welding; E, unclamp nut, unload positioning core axle 4, template 2 and alignment pin 5, two pieces of connecting plates 1 are welded to connect with cylindrical shell 6 and namely complete welding of this loop wheel machine jinny connecting plate peculiar to vessel.
