Description

Folding-jib revolution lathe

The utility model relates to a kind of lathe.

Common common table rig bed comprises support, workbench, column, support, unit head; Close with horizontal operation above the support and fixedly connected; Fixedly connected with column in the support side; Fixedly connected with support in column top; Support is fixedlyed connected with unit head; Unit head comprises motor, equipment; Equipment comprise setting sleeve, have the main shaft that has central through hole, the rotary handle that are positioned at sleeve and become flexibly connect of bearing with sleeve; Alignment of shafts through hole bottom is for installing the standard taper hole of drill bit; Rotary handle is positioned on the sidewall of sleeve and can rotates relatively in the original place, it is that tooth is connected with bearing in the main shaft that rotary handle passes the inner of sleeve lateral wall, can make main shaft upper and lower moving in sleeve by rotating rotary handle, sleeve, motor and support are for fixedlying connected, and main shaft and motor interconnect by belt pulley.Can not left and rightly rotate again because equipment promptly can not upper and lowerly move, this kind bench drill machine tooling scope is little.

The purpose of this utility model provides the big folding-jib revolution lathe of a kind of range of work.

For achieving the above object, the technical scheme that the utility model is taked is: a kind of folding-jib revolution lathe comprises support, workbench, column, support, unit head; Unit head comprises motor, equipment; Equipment comprises sleeve, main shaft, rotary handle; Be characterized in: workbench is fixedlyed connected with column; Support comprises screw thread elevating lever, the bracing frame of upper bracket, lower carriage, setting; Upper bracket right part and column top for can be in horizontal plane relative being rotatably connected, column passes the lower carriage right part and becomes to flexibly connect with it, elevating lever top is passed the upper bracket left part and is become can be rotatably connected relatively with it, and the elevating lever bottom becomes to be threaded with the lower carriage middle part; Motor, equipment and bracing frame be for fixedlying connected, bracing frame right part and lower carriage left part for can be in horizontal plane relative being rotatably connected.

Because the utility model medium-height trestle comprises upper and lower support, screw thread elevating lever, bracing frame; Motor, equipment are fixedlyed connected with bracing frame, and lower carriage can rotate in horizontal plane relatively with bracing frame, and elevating lever and lower carriage be for being threaded, so the rotation and lifting bar just can make that equipment is upper and lower to be moved, thereby can process high and low different workpieces; Upper bracket can rotate relatively with column, lower carriage becomes to flexibly connect with column, therefore upper and lower support can revolve three-sixth turn around column, equipment can rotate around lower carriage, make that the range of work of equipment is more extensive, operating efficiency improves, can be according to producing the different circular arc of needs realization curvilinear motion processing and the material of the high and low gradient in the work.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is a kind of structural representation of the present utility model.

A kind of folding-jib revolution lathe as shown in Figure 1, comprises common support 1, common workbench 2, common column 11, support, common unit head; Unit head comprises common motor 8, common equipment; Equipment comprises common sleeve 4, has the common main shaft 3 of bearing, common rotary handle 5; Support comprises screw thread elevating lever 9, the bracing frame 6 of upper bracket 10, lower carriage 13, setting; Upper bracket 10 is that the left part of a horizontal positioned is that a dull and stereotyped right part is a common sleeve that seals above; Lower carriage 13 is that the flat board, the right part that have a common tapped through hole are the sleeve of a common setting for horizontal positioned, left part; Bracing frame 6 is the flat board of a horizontal positioned; Elevating lever 9 upper ends are that a common handle, bottom are threaded; Be common fixedlying connected with workbench 2 above the support 1; The middle part is common fixedlying connected with column 11 lower ends above the workbench; Column 11 surfaces have helical oil groove 14; Upper bracket 10 right part sleeves and column 11 tops be common can be in horizontal plane relative being rotatably connected, column 11 bottoms are passed lower carriage 13 right part sleeves and are become to flexibly connect with it; Have a common retaining mechanism 12 on the lower carriage middle sleeve right side wall, lower carriage is connected with the column relative fixed; Elevating lever 9 tops pass that upper bracket 10 left parts are dull and stereotyped and become can be rotatably connected relatively with it in horizontal plane, handle is positioned at the upper bracket top in the elevating lever 9, and tapped through hole becomes common being threaded on the middle part flat board in elevating lever 9 lower thread and the lower carriage; Main shaft is positioned at sleeve 4 and becomes common flexible connection with it in the equipment, the main shaft bottom has common standard taper hole, cutleries such as drill bit, milling cutter, grinding, fraising can be installed according to need of work, rotary handle is positioned on the sidewall of sleeve 4, can make main shaft upper and lower moving in sleeve 4 by rotating rotary handle; Motor is connected with main shaft in the equipment by tower belt pulley; Motor is common fixedlying connected with bracing frame 6, equipment middle sleeve 4 is common fixedlying connected with bracing frame, bracing frame right part and lower carriage 13 left parts be common can be in horizontal plane relative being rotatably connected, have a pair of common mutual corresponding retention mechanism 7 on bracing frame and the lower carriage, it can make bracing frame and lower carriage become relative fixed to be connected.Owing to have retaining mechanism on the lower carriage, have retention mechanism on lower carriage and the bracing frame, thereby can avoid the flutter phenomenon that occurs in the process.
