The specific embodiment
Provide structure and the operation principle that embodiment explains the utility model below in conjunction with accompanying drawing.
Shown in accompanying drawing; The autobalance drill centers special machine of the utility model, it has base 5, and the both sides above the base have workpiece jacking mechanism 3 respectively; There is rotary support mechanism 2 at middle part above the base; The top of rotating supporting device is equipped with drilling head mechanism 1 through connecting support 15, and the middle part of rotary support mechanism is equipped with manipulator mechanism 6, and balancing a survey mechanism 4 links together with the workpiece jacking mechanism;
On described rotary support mechanism; Riser 21 is arranged; The riser middle part is equipped with rotating cylinder 26; One end of rotating cylinder is equipped with first hydraulic jack 28, the other end is equipped with index dial 23, and the groove 22 at 90 ° of angles is at interval arranged on the index dial outer rim, and the index dial side has backstay 24 and calibration location magnetic valve 25 to link together; 210 on first gear of installing on the rotating cylinder 27 and first motor are gone up second gear of installing 29 and are meshed together, and the expansion link and the pull bar on the manipulator mechanism 65 of first hydraulic jack link together;
On described manipulator mechanism, pull bar 65 and a pair of arm-tie 63 are hinged, and the middle part that an end of pair of swing bar 62 is hinged on the arm-tie respectively, the other end is fixed with clamping plate 61, two swing arms of band V-shaped groove respectively is hinged on respectively on the outside jacket plates 64;
In described drilling head mechanism; Drill bit 14 links together through the connecting rod 12 and second motor 11; Second motor is fixed on vertical support plate 13; Vertically the expansion link of the support plate and second hydraulic jack 17 links together, and second hydraulic jack is fixed on the horizontal support plate 18, and laterally support plate and stepper motor 16 are installed together;
In described balancing a survey mechanism; The top of bent plate 41 is installed on the edge cover 31 on the workpiece jacking mechanism, and carriage 46 is installed above the bent plate bottom, and spring 45 is arranged above the carriage; Rotary shaft rack 43 is installed above the spring; There is runner 42 end of the rotating shaft 44 of installing on the rotary shaft rack, and runner links together through belt 47 and dynamometer 48, and the expansion link on dynamometer bottom and the 3rd hydraulic jack 49 links together.
Obviously, the utility model also comprises hydraulic system, electrical system and PLC control device.Their concrete structure no longer details, and is prior art.Identical on the concrete structure of described workpiece jacking mechanism and the existing machine tool no longer detailed.
The operation principle of the utility model is, bent axle to be processed is hung in by manual work, is placed in a pair of clamping plate of manipulator mechanism, under the effect of first hydraulic jack, bent axle stepped up.The first motor drives index dial turns clockwise 90 °, and the drill bit in the drilling head mechanism is to the preparatory centering of the small end of bent axle.Then, first motor drives index dial earlier and is rotated counterclockwise 90 °, and bent axle is got back to initial position, and bent axle continues to be rotated counterclockwise 90 ° under the drive of index dial then, and the drill bit in the drilling head mechanism carries out preparatory centering to the big end of bent axle.After this, under the drive of first motor, turn clockwise 90 °, bent axle is got back to initial position.At this moment, the clamping plate on the manipulator mechanism unclamp bent axle, the top bent axle that holds out against on the two workpiece jacking mechanisms, and the pressure size is advisable can guarantee that bent axle freely rotates, and at this moment, the big end of bent axle contacts with runner in the balancing a survey mechanism.Because of the effect of out-of-balance force, bent axle freely turns to the face of laying particular stress on, and arrives vertical lower.The rotation of bent axle drives runner and rotates, and the rotation of runner is through the belt traction dynamometer, and this moment, the PLC control device read storage to the data that dynamometer records.Next, the 3rd hydraulic jack that is connected with dynamometer spurs dynamometer, and dynamometer drives bent axle and rotates through belt, runner, turns to and the original face of the laying particular stress on position at an angle of 90 that freely turns to of bent axle.At this moment, PLC control device data that dynamometer is recorded carry out reading the second time storage.Then; At the pulling dynamometer, the top return on the workpiece jacking mechanism does not unclamp bent axle to the 3rd hydraulic jack; Bent axle freely goes to the face of laying particular stress on position vertically downward again; Clamping plate on the manipulator mechanism clamp bent axle, and the PLC control device is according to the dynamometer data that read for twice, the displacement that calculate the bent axle small end respectively, needs when holding the secondary punching greatly.First motor begins to drive the bent axle action according to the step with preparatory centering; Different is; When small end is beaten the secondary centre bore; Laterally support plate can be moved to the left a displacement (this displacement is the instruction that stepper motor provides to be confirmed according to the data of PID controller by the PLC control device) under the drive of stepper motor, and drill bit etc. move thereupon, so that laying particular stress on of bent axle revised.Equally, when big end is beaten the secondary centre bore, the laterally support plate displacement that under the drive of stepper motor, can move right.After the secondary punching finished, the utility model can carry out secondary to bent axle to be measured, and has only the dynamometer data that read when the PLC control device to reach predefined standard value; Whole flow process just finishes; Otherwise, proceed above-mentioned punching set-up procedure, set requirement until satisfying.After this, artificial bent axle is taken off gets final product.
In balancing a survey mechanism, can regulate the height of rotary shaft rack through spring.
On rotary support mechanism, after index dial rotated, the location magnetic valve drove backstay and moves in the groove on the index dial outer rim, plays positioning action.
