The spring, moving wheel and fixed wheel are sequentially installed to the output axle of motor. The fixed wheel and moving wheel are installed to the mainshaft. Its advantages are stepless speed regulation and no need of stop on regulating speed.
Description
The present invention relates to the machining apparatus technical field, is a kind of bench drill that can realize stepless speed regulation.
Existing bench drill, its power are by the belt pulley transmission, and the size of rotating speed is same by the belt pulley adjustment, make on the present market at home and abroad and sell the wheeled various bench drills of belt that use, and all are with tower belt pulley adjustment rotating speed.Its operating process is: when needs transposing rotating speed, must stop bench drill rotating, open belt housing, unclamp motor and belt, then belt is shifted to another groove by a groove, to realize the purpose of reduction of speed or raising speed, after belt is transposed to needed rotating speed, with belt tension, fixed electrical machinery is built belt housing at last, and the speed governing operation is finished.The deficiency of this speed regulation process is: complicated operation, production efficiency is low, and is absolutely unsafe.In addition, because the groove of cone pulley is limit, can only realize step speed regulation, for example: five speed, 12 speed or the like.
The objective of the invention is, a kind of Berch drill with stepless speed regulation is provided, make it have following advantage: do not need to stop bench drill during speed governing and rotate; Can realize stepless speed regulation; In the operation of processing work, can adjust rotating speed at any time as required; There is not any operational hazards in speed governing safety; Speed governing is efficient and convenient, and production efficiency is increased substantially etc.
The present invention is that the technical scheme of finishing the above-mentioned purpose employing is: it has base, column is installed on the base, casing is installed on the column, main shaft is installed in the casing, motor is installed on the casing, mounting spring, motor driving wheel and motor fixed wheel successively on the output shaft of motor are installed main shaft fixed wheel and main shaft driving wheel successively on the main shaft.The external diameter of motor driving wheel and motor fixed wheel is the shape of changing from small to big.The external diameter of main shaft fixed wheel and main shaft driving wheel is the shape of changing from small to big.Motor driving wheel and motor fixed wheel, two little external diameter end axis direction relative positions are installed; Main shaft fixed wheel and main shaft driving wheel, two little external diameter end axis direction relative positions are installed; Installation shaft bearing on the main shaft, bearing block is connected with the main shaft driving wheel, and bent axle is installed on the bearing block, and bent axle is connected with speed adjusting lever; Mounting flange and frictional disk on the bent axle, pin and the speed adjusting lever installed on the frictional disk are fixed, mounting spring on the ring flange; Mounting flange and handle set on the bent axle are offered several holes on the ring flange, mounting spring and steel ball on the handle set.Main contribution of the present invention is, fixed wheel and driving wheel have been installed respectively on motor output shaft and main shaft, and driving wheel can move axially along motor output shaft and main shaft respectively, with the position of change belt along variable external diameter wheel, thereby reaches the purpose that realizes stepless speed regulation.
The present invention learns through repetition test, has following advantage: do not need to stop bench drill during speed governing and rotate, can realize stepless speed regulation, can adjust the bench drill rotating speed at any time as required in the operation of processing work, speed governing is safe and reliable, does not have any operational hazards, speed governing is efficient and convenient, production efficiency is increased substantially, alleviated labour intensity, low cost of manufacture significantly.
Description of drawings: accompanying drawing 1 is an appearance structure schematic diagram of the present invention, accompanying drawing 2 is structural representations of the present invention, accompanying drawing 3 is plan structure schematic diagrames of arrangements for speed regulation 4 in the accompanying drawing 1, the annexation of main signal bent axle 16 parts such as grade, accompanying drawing 4 is speed regulating structure schematic diagrames of the present invention, position component annexations such as main signal speed adjusting lever 15 and bent axle 16, accompanying drawing 5 is another kind of speed regulating structure schematic diagrames of the present invention, mainly illustrates position component annexations such as speed adjusting lever 15 and bent axle 16.
Contrast above-mentioned accompanying drawing, the present invention is elaborated, 1 is base among the figure, column 2 is installed on the base 1, casing 5 is installed on the column 2, main shaft 12 is installed in the casing 5, motor 3 is installed on the casing 5, mounting spring 7, motor driving wheel 8 and motor fixed wheel 9 successively on the output shaft of motor 3 are installed main shaft fixed wheel 14 and main shaft driving wheel 13 successively on the main shaft 12; The external diameter of motor driving wheel 8 and motor fixed wheel 9 is the shape of changing from small to big; The external diameter of main shaft fixed wheel 14 and main shaft driving wheel 13 is the shape of changing from small to big; Motor driving wheel 8 and motor fixed wheel 9, two little external diameter end axis direction relative positions are installed; Main shaft fixed wheel 14 and main shaft driving wheel 13, two little external diameter end axis direction relative positions are installed.Speed regulating structure of the present invention can have a plurality of schemes, wherein a kind of scheme is: installation shaft bearing 11 on the main shaft 12, bearing block 11 is connected with main shaft driving wheel 13, bent axle 16 is installed on the bearing block 11, bent axle 16 is connected with speed adjusting lever 15, mounting flange 18 and frictional disk 17 on the bent axle 16, the pin of installing on the frictional disk 17 21 is fixing with speed adjusting lever 15, and mounting spring 19 on the ring flange 18.When adopting this structure speed governing, speed adjusting lever 15 is moved, make pin 21 drive frictional disks 17, break away from ring flange 18, rotate speed adjusting lever 15, drive bent axle 16 and rotate, because bent axle 16 is connected with bearing block 11, and then reaches the purpose of mobile main shaft driving wheel 13, realize stepless speed regulation.After speed governing was finished, frictionally is the speed governing position fixedly.That is: the spring force given by spring 19 of frictional disk 17 is close to handle set 22 and frictional disk 17 on the ring flange 18, reaches the fixedly purpose of speed governing position.The present invention also can adopt another kind of speed-regulating scheme, and its structure is: mounting flange 18 and handle set 22 on the bent axle 16, offer several holes 23 on the ring flange 18, mounting spring 25 and steel ball 24 on the handle set 22.When the present invention need adjust the rotating speed of main shaft 12, clockwise rotate speed adjusting lever 15, bent axle 16 is rotated, move on the shifting shaft bearing 11, and then move on the drive main shaft driving wheel 13, this moment, belt 10 was moved to little outer radius by the big outer radius of main shaft fixed wheel 14 and main shaft driving wheel 13, simultaneously, under the effect of spring 7 power, drive on the motor driving wheel 8 and move, from face belt 10 is moved by the little outer radius of motor driving wheel 8 and motor fixed wheel 9 to big outer radius, realize increasing the purpose of main shaft 11 rotating speeds.Backward rotation speed adjusting lever 15, the purpose of then realize slowing down, 6 is workbench among the figure, the present invention does not describe structure in detail, is known technology.
