Description
Technical field
The utility model relates to ribbon conveyer technical field, particularly a kind of cylinder bore hole bracing frame.
Background technology
Because underground mine use ribbon conveyer diameter is larger, the processing of belt belt conveyer roller two ends seam in the past all turns around on boring machine or on vertical lathe to process.Because barrel rolls and forms by steel plate, inevitably there is certain ovality in barrel, on boring machine or vertical lathe turn around to process seam and have clamping phenomenon twice, there is certain ovality owing to rolling cylindrical shell, twice clamping position is inconsistent, benchmark difference, the working axiality of seam is poor, in the time that cylinder disc is assembled, there is disalignment phenomenon, therefore the even property of finished product cylinder wall thickness ununiformity after processing is large, the static balance of cylinder, dynamic balancing is poor, often in the time doing static balancing test, need on the disc of cylinder, weld more counterweight fast, affect the attractive in appearance and quality of cylinder.The technological method for processing of large-scale cylinder seam is that numerous technical staff are unanimously in the problem of Exploration and Research for many years, how can realize cylinder at clamped one time, can improve again that under the circumstances of working (machining) efficiency, to complete the processing of cylinder seam be also the common problems of paying close attention to of machine-building personnel simultaneously.
Utility model content
The purpose of this utility model is to provide the cylinder bore hole bracing frame that a kind of production efficiency is high.
To achieve these goals, the technical scheme that the utility model is taked is: a kind of cylinder bore hole bracing frame, comprise cylinder, on described cylinder, drive mandrel is set, the two ends of drive mandrel are installed and are supported disc, support disc and be connected by holding screw with drive mandrel, support disc and rotate with drive mandrel; Described support disc excircle evenly arranges support carriers apart from cylindrical 80mm ~ 100mm, and support carriers arranges thread mill drilling, puller bolt is set in thread mill drilling and is connected with barrel two end supports.
Preferably, described drive mandrel two ends arrange step locate mode and support disc, on the spoke plate hub of location, are symmetrical arranged set screw hole, and dog screw is arranged on web wheel hub, is connected with drive mandrel by holding screw.
Preferably, on described support disc, welding arranges support carriers.
The processing method that the invention also discloses a kind of bore hole bracing frame, comprises the steps,
1) by support disc is installed, the step surface that is installed on drive mandrel from two ends is installed, dress holding screw, will support disc fixing in drive mandrel, will support disc location, fill puller bolt in supporting on disc support manufacturing, and puller bolt is from interior toward exterior;
2) large-scale cylinder bore hole bracing frame drive mandrel 5 is installed to barrel, dress two end supports disc is to drive mandrel step surface, dress holding screw, two end supports disc is fixed in drive mandrel, filling each puller bolt props up barrel, by adjusting each puller bolt, cylinder is finely tuned, ensure cylinder each point allowance;
3) by the barrel assembly hoisting large-size horizontal lathe assembling, left end lathe chuck clamping drive mandrel left end, rotates with lathe spindle, and right-hand member centre bore adopts thimble, be contained on tail stock, the Tang that lathe tool completes cylinder seam from two ends, cylindrical shell left and right axial feed cuts processing.
The beneficial effects of the utility model are: by drive mandrel is set on cylinder, axle two ends are installed and supported disc, support disc and are connected by holding screw with drive mandrel, support disc and can rotate with drive mandrel.Supporting the upper outside circumferential distance cylindrical 80mm ~ 100mm of disc uniform welding support carriers, thread mill drilling is set in support carriers, dress puller bolt, by barrel two end supports, reserves feed space, can on large-size horizontal lathe, complete the processing of cylinder seam.Power transmission shaft two ends arrange step positioning supports disc, on the spoke plate hub of location, be symmetrical arranged set screw hole, dog screw is arranged on web wheel hub, be connected with drive mandrel by holding screw, dress supports the support carriers of welding on disc, as the stressed part of back-up roller cylindrical shell, supporting seat will meet the requirement of support strength.Puller bolt length meets, and back-up roller regulates the requirement of length.This bracing or strutting arrangement Jian is complete, and machining accuracy is high, production efficiency is high.Construction bolt jacking mechanism on bracing frame disc, met the requirement that barrel rotates with mandrel, each puller bolt that simultaneously distributing on disc, through the length of adjusting bolt, can borrow cutter processing owing to rolling the oval problem existing to barrel, be conducive to ensure the uniformity of cylinder wall thickness.

Detailed description of the invention
In order to deepen, to understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model to be further described, this embodiment only, for explaining the utility model, does not form the restriction of the utility model protection domain.
Shown in accompanying drawing 1-2, Fig. 1 is cylinder bore hole support frame structure; Fig. 3 cylinder bore hole bracing frame uses mounting structure schematic diagram.By support disc 3 is installed, the step surface that is installed on drive mandrel 5 from two ends is installed, dress holding screw 4, will support disc 3 fixing in drive mandrel 5, will support disc location.Dress puller bolt 1 is in supporting on disc support manufacturing, and puller bolt 1 is from interior toward exterior.
Cylinder bore hole bracing frame drive mandrel 5 is installed to barrel, dress two end supports disc 3 is to drive mandrel 5 step surfaces, dress holding screw 4, two end supports disc 3 is fixed in drive mandrel, filling each puller bolt 2 props up barrel 6, by adjusting each puller bolt 2, cylinder is finely tuned, ensure cylinder each point allowance.By on the barrel assembly hoisting large-size horizontal lathe assembling, left end lathe chuck 9 clamps drive mandrel 5 left ends, rotates with lathe spindle, and right-hand member centre bore adopts thimble 8, be contained on tail stock, the Tang that lathe tool 7 completes cylinder seam from two ends, cylindrical shell left and right axial feed cuts processing.Compared with prior art, this cylinder bore hole bracing frame is complete by this bracing or strutting arrangement Jian of use procedure, and machining accuracy is high, production efficiency is high.
The disclosed manufacturing procedure of the technical program tool have the following advantages: cylinder processing employing clamped one time completes the processing of both ends of the surface seam, have ensured the axiality of two ends seams.Adopt clamped one time location to process two ends seam, production efficiency is high simultaneously, has reduced and has turned around to process secondary location smoothing phenomenon.Adopt drive mandrel 5 to locate, support carriers 1 scope of application is wide, supports disc 3 by replacing, can process the cylinder of different-diameter.Construction bolt jacking mechanism on bracing frame disc 3, met the requirement that barrel rotates with drive mandrel 5, each puller bolt is distributing on disc simultaneously, see through the length of adjusting bolt, can borrow cutter processing owing to rolling the oval problem existing to barrel 6, be conducive to ensure the uniformity of cylinder wall thickness.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
