The beneficial effect that the utility model compared with prior art has.
The utility model has around the column rotational angle after the posture adjustment of variable cross-section workpiece, and the upper and lower rocking arm of adjustable angle can rotate respective angles according to different workpieces.Passive POGO post and upper rocker arm on the lower shake-changing arm have automatic following feature in the Z direction.The flexible compact heap that passive POGO post upper cylinder drives can adapt to different gradient work, can follow the aerofoil height automatically, and clamps fixing variable cross-section workpiece under little applied external force, and realization 20N clamps with interior additional stress and loosens.The drive unit that base upper edge directions X moves can make the workpiece turnover convenient, satisfies the different workpieces position.Its position locking device can reduce the intersection point hole and add workpiece and clamping device vibration in man-hour.
Description of drawings
Fig. 1 is the clamping holding unit structural representation of the utility model butt joint assembling variable cross-section workpiece.
Fig. 2 is that the fastening device of holding of the utility model variable cross-section workpiece clamp is gone into the working state schematic representation of position after finishing.
Among the figure: 1 base, 2 servomotors, 3 decelerators, 4 gears, 5 cylinders, 6 guiding mechanisms, 7 locking heads, 8 columns, 9 lower shake-changing arms, 10 sleeves, 11 upper rocker arms, 12 lockers, 13 passive POGO posts, 14 cylinders, 15 guiding mechanisms, 16 compact heaps.
The specific embodiment
As shown in Figure 1 and Figure 2.The fastening device of holding of variable cross-section workpiece clamp of butt joint assembling variable cross-section workpiece comprises, has the drive unit of decelerator and the base 1 of position locking device, and the column 8 that links to each other with base 1 and around the upper rocker arm 11 and the lower shake-changing arm 9 of column 8 rotations.Base 1 box body inner chamber is provided with the decelerator 3 that links to each other with servomotor 2 main shafts.Gear 4 protuberate basic units 1 box body of connection reducer 3, and form the drive unit that drives base 1 upper end column 8.This drive unit moves the clamping device directions X, can make the workpiece turnover convenient, the position of satisfying different workpieces.By the position locking device of base 1 box body, form with the locking head 7 that links to each other with guiding mechanism 6 by the guiding mechanism 6 that is assemblied in the cylinder 5.The cylinder 5 of the position locking device of its formation drives locking heads 7 and moves upward and contact Strain lock with scotch on the track base and grip tight device, make its can reduce the intersection point hole add man-hour workpiece and clamping device vibrate.Column 8 links to each other with base 1 by sleeve 10.Lower shake-changing arm 9 and upper rocker arm 11 rotate around column 8 by sleeve.Upper and lower rocking arm 11,9 is provided with the locker 12 of locking rotational angle, and locker 12 locking angular ranges are ± 30 °.Upper rocker arm 11 terminations are provided with the guiding mechanism 15 that moves in cylinder 14 cylinder bodies.Guiding mechanism 15 is fixedly connected with flexible compact heap 16, and this flexible compact heap 16 has been connected automatic following feature, has again on the ballhead pair that clamps function, and the ballhead pair that can adapt to different gradients connects firmly with guiding mechanism 15 guide posts.Compact heap 16 is ± 10 ° with the secondary adjusting range that is connected of guiding mechanism ballhead.Be provided with at least two passive POGO posts 13 in lower shake-changing arm 9 terminations.The two passive POGO posts 13 that parallel rise by hydraulic means and contact with the variable cross-section workpiece, and the vacuum cup bulb on it is 0～150mm along the adjusting range of Z direction, and the vacuum cup bulb is by hydraulic locking.During work, the variable cross-section workpiece is between the flexible compact heap 16 on passive POGO post 13 and the upper rocker arm 11.At this moment, the passive POGO post 13 on the lower shake-changing arm 11, the flexible compact heap 16 that drives with the cylinder guidance mechanism of upper rocker arm 11 forms and compresses, and following vacuum suction clamps the holding unit of variable cross-section workpiece.
The course of work of the present utility model is as follows: at first press aircraft model variable cross-section workpiece or horizontal tail and adjust upper rocker arm 11, rotate the angle of lower shake-changing arm 9 and use locker 12 lockings around column 8.After adjust above-mentioned mechanical system locus, by 4 motions of decelerator 3 driven gears, make clamping device to the operating position by servomotor 2.After cylinder 5 air inlets in the position locking device, drive locking head 7 and move upward and contact Strain lock with scotch on the track base and grip tight device.Passive POGO post 13 air inlets on the lower shake-changing arm 9, the band sucker bulb in the passive POGO post are risen and are contacted passive POGO post 13 of hydraulic locking and vacuum suction sucker bulb with the variable cross-section workpiece.Cylinder 14 air inlets on the upper rocker arm 11 drive flexible compact heap 16 and move downward and compress the variable cross-section workpiece, and unclamp cylinder 14 briquettings and move upward.Passive POGO post 13 unclamps hydraulic locking, and stops vacuum suction.The duty of fixing variable cross-section workpiece is withdrawed from passive POGO post upper end gas port air inlet this moment, unclamps cylinder 5, unclamps clamping device.Simultaneously, servomotor 2 makes clamping device get back to initial position by 4 motions of decelerator 3 driven gears, enters the next round readiness for operation.
