Description

Tightening machine

Technical field

The utility model relates to a kind of tightening machine.

Background technology

Be used for the tightening machine on the production line at present; Mainly connect and compose by motor, reducing gear and retention mechanism, itself since reducing gear with tighten on the axis that mechanism all is positioned at motor output shaft, promptly the tightening machine combination head is to extend axially; Needed assembly space is big, influences production efficiency.And adopting artificial mode of tightening generally all to be to use spanner with nut screwing clamping, it can't the budget screwing force in rotary course, when nut screwing clamping, occurs overexertion easily, causes nut to damage.Automaticity is not high, can not satisfy the production operation needs.

The utility model content

The purpose of the utility model provides a kind of tightening machine, and high efficiency helps safety in production, to have overcome the above-mentioned deficiency of present existing product.

The purpose of the utility model is to realize through following technical scheme:

A kind of tightening machine; Comprise support; Be symmetrically installed with on the said support and tighten mechanism, tighten mechanism and comprise transmission device, detect valve mechanism and clamping device, transmission device comprises slide rail post that is fixedly installed in a top of the trellis and the cylinder I that is arranged at the slide rail column top; Be provided with slide rail in the slide rail post, cylinder I end joint detection valve mechanism; Said detection valve mechanism comprises and moves up and down platform and interconnect and be arranged at the motor that moves up and down on the platform and detect valve through gear; Move up and down platform one end and connect slide rail; Detect tappet head is installed in the valve, tighten first end and pass and move up and down platform to extending below and through the locking of conical pipe locking device; Detect the valve mechanism below and be provided with clamping device, clamping device comprises the cylinder fixed support, be arranged at cylinder I I and the symmetry in the cylinder fixed support and be movably installed in the intermediate plate of cylinder I I both sides.

The beneficial effect of the utility model is: threaded together class interface workpiece, frock etc. automatically, improved operating efficiency; For can directly installing with the inconvenient place of personnel in the line running body; Help realizing that the automation installation realizes the production automation and unmanned; Help safety in production.

Among the figure:

1, support; 21, transmission device; 211, slide rail post; 212, cylinder I; 213, slide rail; 22, detect valve mechanism; 221, move up and down platform; 222, gear; 223, motor; 224, detect valve; 225, tappet head; 226, conical pipe locking device; 23, clamping device; 231, cylinder fixed support; 232, cylinder I I; 233, intermediate plate; 3, workpiece; 4, workpiece mobile platform.

The specific embodiment

Shown in Fig. 1-5; The described tightening machine of the utility model embodiment comprises support 1, is symmetrically installed with on the said support 1 and tightens mechanism; The said mechanism of tightening comprises transmission device 21, detects valve mechanism 22 and clamping device 23; Transmission device 21 comprises slide rail post 211 that is fixedly installed in support 1 top and the cylinder I 212 that is arranged at slide rail post 211 tops, is provided with slide rail 213 in the slide rail post 211, cylinder I 212 end joint detection valve mechanisms 22; Said detection valve mechanism 22 comprises and moves up and down platform 221 and interconnect and be arranged at the motor that moves up and down on the platform 221 223 and detect valve 224 through gear 222; Move up and down platform 221 1 ends and connect slide rail 213; Detect tappet head 225 is installed in the valve 224, tappet head 225 1 ends pass and move up and down platform 221 to extending below and locking device 226 lockings through conical pipe; Detect valve mechanism 22 belows and be provided with clamping device 23, clamping device 23 comprises cylinder fixed support 231, be arranged at cylinder I I232 and the symmetry in the cylinder fixed support 231 and be movably installed in the intermediate plate 233 of cylinder I I232 both sides.

During concrete the use; When workpiece 3 moved to the described a kind of tightening machine lower position of the utility model embodiment through workpiece mobile platform 4, cylinder I 212 rose and makes clamping device 23 inside clamping work pieces 3 and make workpiece 3 position accurate positionings, and workpiece 3 is alignd with tappet head 225; Cylinder I I232 action when workpiece 3 position accurate positionings; Make and detect valve mechanism 22 declines, motor 223 actions simultaneously drive and detect valve 224 rotations, accomplish and tighten action automatically.Tighten action and utilize friction plate friction generates moment of torsion to tighten, when regulating moment of torsion that friction plate produces and be less than or equal to prescribed torque, motor 223 still can normal rotation, but gear 222 do not rotate, thereby has well protected gear 222 and screw thread.

When testing was accomplished, motor 222 counter-rotatings were accomplished and are unloaded valve events, and cylinder I I232 action makes detection valve mechanism 22 rise to original position; Cylinder I 212 descends; Thereby unclamp clamping device 23 and decontrol workpiece 3, workpiece 3 is removed through workpiece mobile platform 4, carries out tightening of next workpiece 3; Unmanned and automation, high efficiency have been realized producing.

The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within the protection domain of the utility model.
