The present invention is owing to take above technical scheme, and it has the following advantages: 1, the present invention includes tighten, riveting rushes two stations, tightens station and comprises an electric twisting spanner, torque spanner is by computer control torsion; Riveting is rushed station and is comprised a riveting drift by the oil cylinder drive, and the riveting drift is led by guiding mechanism, and the riveting punching is finished in motion; Also comprise and be arranged on the other security sweep light curtain of two stations.Not only simple to operate, and safe and reliable, and high efficiency, processing high conformity, easy to maintenance are one of special equipments crucial in the shock absorber batch production process, are applicable to the wider range damper linking member and restore tightening of nut and connecting rod riveting punching.2, the present invention quoted U.S.'s Ingersoll-rand electric wrench, improved restore nut tighten precision level and uniformity, also increased hydraulic system, pneumatic system and electrical control, realized automatic operation, improved production efficiency and alleviated labour intensity.Wherein electrical equipment control is the PLC Programmable Logic Controller, and instruction hydraulic pressure, pneumatic system are finished the action of requirement.
Description of drawings
Fig. 1 is this practical structural representation.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the present invention includes tighten, two stations of riveting punching, be arranged side by side in the front of cabinet.Tightening station comprises fastening device 1, upper clamping and positioning device 2 and tightens clamping device 3; Riveting is rushed station and is comprised that positioner 5 is rushed in equipment for riveting and punching 4, riveting and clamping device 6 is rushed in riveting.
The fastening device 1 that tightens in the station comprises an electric twisting spanner 11, torque spanner 11 is supported on the wrench rack 12, wrench rack 12 is along the guiding mechanism guiding that is located on the cabinet panel, driven by wrench rack cylinder 13, when the wrench rack cylinder starts, can be with wrench support 12 and torque spanner 11 together mobile.Torque spanner 11 can also be to be slidingly installed on the wrench rack, driven at wrench rack by a fine setting cylinder mobile, like this, but under the wrench rack cylinder drives the position of coarse adjustment spanner, under the drive of fine setting cylinder, can accurately aim at spanner and restore the position of nut.
Behind station on the workpiece, regulate first upper clamping and positioning device 2, make workpiece that a suitable height (can be adjusted to purpose with torque spanner) be arranged, then startup tightens clamping device 3 clampings.After reserving station, at first start wrench rack cylinder 13, according to the rough mobile spanner of the height of workpiece, spanner is alignd substantially with nut; Then start the fine setting cylinder, spanner is contacted with nut, start simultaneously the torque spanner motor, spanner is crept into screw nut.The clamp load torque of torque spanner is that torque value and the angle of restoring nut according to workpiece in advance are stored in spanner controller 14, can call at any time in the production operation process.
The equipment for riveting and punching 4 that riveting is rushed in the station comprises the riveting drift 41 that is driven by oil cylinder, the riveting drift is installed on the guiding mechanism 42, and this guiding mechanism comprises two guide rails that be arranged in parallel, the sliding adjusting seat 43 of establishing between two guide rails, the riveting drift is located on the adjusting seat, and head exposes.The riveting drift moves along guide rail under the drive of oil cylinder 44, and the position is not offset when guaranteeing that riveting is rushed.
Tightening station and riveting rushes station and includes positioner and clamping device, usually, positioner comprises a supporting seat, at supporting seat chute 21,51 is set, one locking sliding block 22,52 is set in the chute, slide block (or passing through mold) is against the workpiece bottom, can suitably adjust according to the length of workpiece the position of slide block, then locking; Perhaps, can one screw/nut be set at supporting seat, the station of the length adjustment workpiece by adjusting screw rod, screw rod upper end (or passing through mold) props up workpiece, and nut is used for tie down screw.
Clamping device is an oil cylinder 31,61, and the bail 32,62 that drives, and is used for clamping work pieces.With the back-moving spring (not shown), when piston rod is released, promote bail and tighten up on the bail, clamp workpiece; When piston rod was return, spring drove bail and gives up the throne, and unclamps workpiece.Clamping device also can be a simple annular clip, is tightened by bolts.
The present invention also is included in and tightens station arranged on left and right sides and riveting and rush each one pair of security sweep light curtain 7,8 that arranges of station arranged on left and right sides.When equipment worked, the operator put in hand or other article mistake processing space namely between the two light curtains time because of carelessness, and security sweep light curtain works, and at once shuts down, and plays the safeguard protection effect.If continue processing, answer manual operation to make each parts be back to initial duty, then by the pertinent regulations operation, can work on.
Above-described embodiment only is used for explanation the present invention, and wherein the structure of each parts, connected mode etc. all can change to some extent, and every equivalents and improvement of carrying out on the basis of technical solution of the present invention all should do not got rid of outside protection scope of the present invention.
