Abstract
The present invention relates to a stepless frequency control power boring head. The worm of the boring head is connected with the power shaft of a variable frequency motor (5). The variable frequency motor (5) is electrically connected with a frequency converter (19). A first thrust bearing (6) is arranged on the worm at the end connected with the power shaft of the variable frequency motor (5), and a second thrust bearing (8) is arranged on the other end. A turbine and a main shaft are assembled and connected by a key slot (11) and a locating screw (12). The boring head can realize stepless speed regulation through frequency conversion. The present invention has the advantages of simple structure, small volume, constant torque, easy manufacture, production and maintenance, convenient operation, balance running, smooth speed regulation, no noise and no vibration. Best cutting linear speed can be regulated for processing various bores.
Description
Technical field
The invention belongs to the boring head technical field.
Background technology
The turbine shaft of hydraulic generator and engine shaft to connect with boring be important manufacturing procedure during the hydraulic turbine is produced, one group of Generator Set of every production all needs the same boring of shaft coupling, process used power boring head and often need multiple rotating speed, to satisfy the needs in the various apertures of processing.The used turbine shaft of prior art connects the boring head with boring with engine shaft, its deceleration device is made up of motor, belt drive unit, worm screw turbine, clutch, gear reduction box etc., usually have only fixed rotating speed below three kinds, can not satisfy the optimized cutting linear velocity requirement in big and small various apertures.
Summary of the invention
Purpose of the present invention provides a kind of demand that can satisfy various aperture processing cutting linear velocities just in order to solve the deficiencies in the prior art, the stepless frequency control power boring head of various different rotating speeds can be provided.
The objective of the invention is to be achieved through the following technical solutions.
Stepless frequency control power boring head, the worm screw of its speed change gear connects with the line shaft of variable-frequency motor, variable-frequency motor is electrically connected with frequency converter, an end that connects with the variable-frequency motor line shaft worm screw is equipped with first thrust bearing, the other end is equipped with second thrust bearing, and is equipped with dog screw and be connected by keyway between turbine and the main shaft.
The present invention is provided with end ring at an end of the close main shaft of first thrust bearing, and the other end is provided with adjusting pad.Described frequency converter is the FR-700 frequency converter.Between rear end location bearing and rear end bearing lid, be provided with packing ring and fastening screw nut.
The present invention can realize variable-frequency stepless speed-regulating, and it is simple in structure, and the bodily form is little, and permanent torque is easy to make, produces and safeguards, and is easy to operate, the operation balance, and speed change is level and smooth, noiseless, friction is processed various apertures and can both be found the optimized cutting linear velocity.
Further set forth content of the present invention below in conjunction with Figure of description.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 adopts the present invention to carry out turbine shaft to connect schematic diagram with boring with engine shaft.
The specific embodiment
As shown in Figure 1, the present invention includes cabinet 3 and be installed on main shaft in the cabinet, the rear end bearing lid 18, the middle part location bearing 7 that are separately installed with front end location bearing 2 and the preceding end bearing cover 1 that seals, rear end location bearing 15 at the two ends of main shaft and middle part and seal.Front end location bearing 2, rear end location bearing 15 and middle part location bearing 7 are used to guarantee the running accuracy of main shaft.Main shaft 4 is used to install the knife bar and the cutter in the various apertures of boring.Cabinet 3 can be installed on the knife rest position of sleeping carriage, with the motion feeding bore hole of saddle.Location bearing is fitted with turbine vertical with main shaft 10 and worm screw 9 at next-door neighbour middle part, main shaft middle part, worm screw connects with the line shaft of variable-frequency motor 5, variable-frequency motor is electrically connected with frequency converter 19, an end that connects with the variable-frequency motor line shaft worm screw is equipped with first thrust bearing 6, the other end is equipped with second thrust bearing 8, to carry out the worm screw location.End at first thrust bearing, 6 close main shafts is provided with end ring 13, and the other end is provided with adjusting pad 14, is used to adjust the gap between first thrust bearing 6 and second thrust bearing 8.Between rear end location bearing 15 and rear end bearing lid 18, be provided with packing ring 16 and fastening screw nut 17, be used to adjust the axial and radial clearance of front end location bearing 2 and rear end location bearing 15.Equipped and is connected between turbine and the main shaft by keyway 11 and dog screw 12, rotate in the main shaft slippage to prevent worm gear, the drive main shaft steadily rotates.Frequency converter 19 adopts the FR-700 of Mitsubishi frequency converter, and variable-frequency motor adopts YPT type variable-frequency motor.The FR-700 frequency converter is used to select the frequency conversion scope, and the alternating current that variable-frequency motor 5 is imported the different frequency section as required obtains corresponding rotating speeds.Add man-hour, the rotating speed of setting on the frequency converter according to the rated speed of the speed ratio of worm and gear and variable-frequency motor shows, with the actual speed of correct demonstration main shaft.During design, according to processing pore diameter range, cutting force, linear velocity correct select rated power, rated voltage, rated frequency, motor pole number, number of threads, the worm gear number of teeth or other transmission speed ratio for use, the speed of doing on frequency converter is set.Frequency converter can make electric efficiency obtain the raising of amplitude peak, further realizes energy-saving run.
Carry out turbine shaft when connecting with boring with engine shaft, as shown in Figure 2, turbine shaft a and engine shaft b are contained on the lathe simultaneously, supported by preceding centre frame c and the frame d of rear center, clamped by chuck, tailstock e holds out against.Lathe spindle is shut down, and middle carriage is switched on separately and driven the stepless frequency control power boring head f left and right sides rectilinear motion that is contained in the knife rest position.Boring head dress knife bar g and cutter h, knife bar g rotation can boring shaft coupling hole i.
