Description
Technical field
The utility model relates to a kind of rocker arm body technical field of common desk-top radial drilling machine.
Background technology
Common desk-top radial drilling machine, because the congenital structural limitations that can not on rocking arm, move by main shaft, in same rocking arm pendulum position, to finish the centering drilling, just can only rely on artificial travelling workpiece tool setting centering, there is following drawback at least in such operation: the first does not have the clamping fixation workpiece, poor location, institute's drilling aperture maximum can only arrive 16mm, has great potential safety hazard during hand steered drilling; Its two be fully by the travelling workpiece centering to finish drilling, waste time and energy, institute drawbore position can only be the axle center with the column, is that zone, overlayable drawbore position is less on one section circular arc line of radius with column to the distance of main shaft or knife bar axis.
Summary of the invention
The purpose of this utility model be to provide a kind of workpiece fixedly clamping on workbench, need not hand steeredly, can improve the centering precision, and enlarge the desk-top radial drilling machine that the rocking arm of processing coverage, handling safety can be rolled over.
The purpose that the utility model is is achieved through the following technical solutions.
The desk-top radial drilling machine that a kind of rocking arm can be rolled over, mainly comprise column, be installed on the column and can change the rocking arm of pendulum, the transmission device that drives the rotation of knife bar main shaft and the motor of drive transmission around column, described rocking arm comprises can be changeed the principal arm of pendulum and change the folding arm of putting around axis around column, and axis vertically is installed on the principal arm and with locking device and is locked; Transmission device is provided with the two-stage transmission, on axis top the transition axis parts are installed, the driving wheel of the follower of one-level transmission and secondary transmission all connects with the transition axis parts, and the driving wheel of one-level transmission is installed on the motor output shaft, and the follower of secondary transmission is installed on main shaft top.
Transition axis parts described in the utility model are installed on the top of axis, comprise mandrel, be sleeved on hollow transition axis, a lining bearing on the mandrel, tighten nut and following clamp nut.
One-level transmission described in the utility model is the V belt transmission, and turriform is installed on driving wheel on the motor output shaft, V belt by falling with key connecting, the follower that is installed on the hollow transition axis top of transition axis parts with the positive turriform of key connecting is formed; The secondary transmission is synchronously band or V belt transmission, the driving wheel that is made of one by the hollow transition axis with the transition axis parts, driving-belt and formed with the follower that key connecting is installed on main shaft top.
The utility model has the following advantages at least:
1, rocking arm is divided into around the principal arm of column commentaries on classics pendulum and folding arm two parts of putting around the axis commentaries on classics, because there are two pivot point in rocking arm, realized that rocking arm can roll over, be installed on cutter on the knife bar main shaft bore can rocking arm can prolong and working face on optional position tool setting centering, the labour during economization travelling workpiece centering.
2, can with workpiece to be processed fixedly clamping on workbench, and need not hand steered workpiece, improved the security of processing.
3, because workpiece is fixed, and the tool setting positioning accuracy significantly improves during drilling, thus can be with drilling aperture expanded range to φ 25mm.
4, the face zone is expanded as by the line zone of prior art in the zone, drawbore position that cutter can be covered.To move to the column be the axle center to main shaft in theory, any point in the circle of radius with column to the ultimate range of main shaft or knife bar axis, can in a clamping, finish the drilling of porous on the workpiece single face, solve the conventional rocker drilling machine and can only finish workpiece is moved to the deficiency of carrying out the drilling of position, hole on one section circular arc line.
5, the utility model is designed to two-stage with transmission device dexterously, has both realized that rocking arm can roll over, and does not also influence the power transmission when carrying out the folding arm operation; Neither change the centre-to-centre spacing of two-stage power transmission shaft, can make folding arm and power transmission carrying out simultaneously mutually noninterfere again.
The utility model is simple in structure, and is easy to operate and safe, has practical value.
Further set forth content of the present utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is that the utility model is installed on the structural representation on the radial drilling machine;
Fig. 2 is the structural representation of the utility model secondary transmission;
Fig. 3 is the utility model axis locking device structure schematic diagram.
The specific embodiment
As shown in Figure 1, the utility model mainly comprises column 10, be installed on rocking arm on the column, drive the transmission device that knife bar main shaft 5 rotates and the motor 9 of drive transmission; rocking arm comprises can be changeed the principal arm 1 of pendulum and change the folding arm 4 of pendulum around axis 2 around column 10; axis 2 vertically interts and is assemblied on the principal arm 1 and is locked with locking device 3, and axis 2 plays not only can be installed transition axis parts 7 at an upper portion thereof but also can play the effect that folding arm 4 waves joint pin.
As shown in Figure 2, when the utility model carries out the folding arm operation in order to be implemented in, do not influence the transmission of power, transmission device is provided with the two-stage transmission, transition axis parts 7 is installed to finish the power transfer on axis 2 tops.One-level transmission 8 is the V belt transmission, and turriform is installed on driving wheel 8a, V belt 8b on motor 9 output shafts by falling with key connecting, the follower 8c that is installed on the hollow transition axis 7d top of transition axis parts 7 with the positive turriform of key connecting is formed for it.Transition axis parts 7 are installed on the top of axis 2, its by mandrel 7a, bearing 7b, a lining bearing 7b be sleeved on hollow transition axis 7d on the mandrel 7a, clamp nut 7c is formed with 7e and packing ring thereof up and down.The upper end cylindrical of hollow transition axis 7d is made shaft extension, with key connecting, with the usefulness that work is installed the follower 8c of one-level transmission 8, the lower end cylindrical is designed to belt wheel, to make the driving wheel 6a of secondary transmission 6, promptly the hollow transition axis 7d of transition axis parts 7 and the driving wheel 6a of secondary transmission 6 are made of one dual-purpose.Because the effect of bearing 7b is arranged, transition member 7 is not waved operation with folding arm and is interfered when the rotation of transmission power.Secondary transmission 6 is synchronously band or V belt transmission, driving wheel 6a, the driving-belt 6b that it is made of one by the hollow transition axis 7d with transition axis parts 7 and formed with the follower 6c that key connecting is installed on main shaft 5 tops.The follower 8c of one-level transmission 8 and the driving wheel 6a of secondary transmission 6 all connect with transition axis parts 7, can run-in synchronism.
As shown in Figure 3, the utility model adopts 3 pairs of axis 2 of axis locking device to be locked, and folding arm is stable during with the realization drilling.Its locking is achieved in that the handle 3a that clockwise rotates axis locking device 3, handle 3a and lock sleeve 3b axially can not move, the screw thread of handle 3a left end drives lock sleeve 3c and moves axially to lock sleeve 3b, is clamped in the enough normal pressures of generation on the axis 2 and locks until two lock sleeves.
