Background technology

Bearing block boring be a difficult working procedure, the severe problem of construction environment should be overcome, consider again into Jackshaft makes narrow space, there is potential safety hazard, and the construction space of these serial ships such as 59M, 65M is narrower, narrow Narrow space is walked about all highly difficult, and personal security cannot ensure, along with the height of bearing block, and air drill must be brought Go, be afraid of to be damaged to jackshaft again.The hole leaning on bulkhead at those is also difficult to get into, and the drill bit that must buy special lengthening, to bore, bores Plumber's cooperation dismounting pipe is also needed to during hole, after being drilled hole, health difficult cleaning again, affect construction period, and the hole coming outbreak out is also Can offset a little, and then affect the construction of next process.

Utility model content

In order to overcome the defect of above-mentioned prior art, technical problem to be solved in the utility model is to provide one kind to be used for The jackshaft preboring hole tool of prebored hole on the bearing block of jackshaft, it is to avoid the later stage hole on bearing block exist be difficult apply Work, personal security cannot ensure, the low problem of easy damaged jackshaft, machining accuracy.

In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is：

A kind of jackshaft preboring hole tool, for prebored hole on the bearing block of jackshaft, including benchmark frame, described base Quasi- frame by benchmark long while, benchmark broadside and connect benchmark long while and the hypotenuse of benchmark broadside enclose and form, two benchmark are long Spacing between side is equal to the width of bearing block base, benchmark long while midpoint be provided with for long with bearing block base while The first datum line that midpoint aligns, the spacing between two benchmark broadsides is equal to the length of bearing block base, benchmark broadside Midpoint is provided with the second datum line aligning for the broadside midpoint with bearing block base, four hypotenuses respectively with bearing block The prebored hole point of four edges of base corresponds setting, every hypotenuse offers logical corresponding to respective prebored hole point Hole, removable in described through hole bushing is installed, the aperture of described bushing is consistent with the aperture of prebored hole.

Wherein, described benchmark frame is made of cast iron.

Wherein, described benchmark frame is integrally formed.

Wherein, described bushing is rustless steel bushing.

Wherein, described bushing is connected with the through hole whorl of hypotenuse.

The beneficial effects of the utility model are：The jackshaft preboring hole tool that this utility model provides, can exist in advance Hole on the bearing block of jackshaft, it is to avoid hole on bearing block in the later stage, being difficult of existing is constructed, personal security cannot be protected Barrier, easy damaged jackshaft, the low problem of machining accuracy, greatly reduce construction cost, improve working security, machining accuracy Height, and the cleaning after holing also is more convenient.

Brief description

Fig. 1 show the structural representation of the jackshaft preboring hole tool of this utility model embodiment.

Label declaration：

The long side of 1- benchmark；2- benchmark broadside；3- hypotenuse；4- bushing.

Specific embodiment

By describing technology contents of the present utility model in detail, being realized purpose and effect, below in conjunction with embodiment and join Close accompanying drawing to be explained.

Refer to shown in Fig. 1, the jackshaft preboring hole tool that this utility model provides, for the bearing block in jackshaft Prebored hole, including benchmark frame, described benchmark frame by benchmark long while 1, benchmark broadside 2 and connect benchmark long while 1 and benchmark The hypotenuse 3 of broadside 2 encloses composition, and the spacing between the long side 1 of two benchmark is equal to the width of bearing block base, the long side of benchmark 1 Midpoint is provided with the first datum line aligning for the long side midpoint with bearing block base, between two benchmark broadsides 2 Spacing is equal to the length of bearing block base, and the midpoint of benchmark broadside 2 is provided with for the broadside midpoint phase with bearing block base Second datum line of alignment, four hypotenuses 3 correspond setting with the prebored hole point of four edges of bearing block base respectively, Offer through hole corresponding to respective prebored hole point on every hypotenuse 3, removable in described through hole bushing 4, described bushing 4 are installed Aperture consistent with the aperture of prebored hole.

During use, benchmark frame is set on bearing block, the first datum line is alignd with the long side midpoint of bearing block base, the Two datum lines are alignd with the broadside midpoint of bearing block base, and the hole then drill bit being directed at each bushing 4 is entered to bearing block base Row boring, you can get out the hole of needs on four corners of bearing block base respectively, structure is simple, easy to operate, boring essence Degree is high.When the hole of bushing occurs abrasion, bushing can be pulled down from through hole and be changed.

Knowable to foregoing description, the beneficial effects of the utility model are：The jackshaft prebored hole that this utility model provides Frock, can hole in advance on the bearing block of jackshaft, it is to avoid the later stage hole on bearing block being difficult of existing construct, people Member's safety cannot ensure, the low problem of easy damaged jackshaft, machining accuracy, greatly reduces construction cost, improves construction peace Quan Xing, machining accuracy is high, and the cleaning after holing also is more convenient.

Further, described benchmark frame is made of cast iron.

Further, described benchmark frame is integrally formed.

Further, described bushing 4 is rustless steel bushing.

Further, described bushing 4 is connected with the through hole whorl of hypotenuse 3.

The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every The equivalents made using this utility model description and accompanying drawing content, or directly or indirectly it is used in the technology neck of correlation Domain, is all included in the same manner in scope of patent protection of the present utility model.
