When specifically used
It is moved before and after automatic locking screw machine by X-axis moves left and right device 2 in present embodiment, Z axis moves up and down device 5 and Y-axis Dynamic device 6 completes the work of soket head cap screw alignment threaded hole, structure include: stepper motor 201, stepping motor bracket 202, Shaft coupling 203, X-axis support plate 204, ball guide screw nat 205, straight-line rolling guide set 206, bearing block 207, bearing 208, Locking nut 209, stepper motor 501, stepping motor bracket 504, Z axis support plate 502, shaft coupling 503, bearing 506, deep-groove ball Bearing 5061, thrust ball bearing 5062, freewheel clutch 5063, friction plate 5064, bearing block 505, ball guide screw nat 507, straight-line rolling guide set 508 and locking nut 509, stepper motor 601, stepping motor bracket 602, shaft coupling 603, straight line Rolling guide-rail pairs 604, ball guide screw nat 611, Y-axis support plate 605, bearing 606, bearing block 607, workbench 608, twin shaft Fixed cylinder 609 and locking nut 610.Stepper motor 201 crosses shaft coupling 203 and the lead screw of ball guide screw nat 205 is driven to turn The dynamic and then ball nut of drive above, which moves left and right, realizes that soket head cap screw moves left and right;Stepper motor 601 crosses shaft coupling 603 The lead screw rotation and then the ball nut of drive above for driving ball guide screw nat 611 move left and right before realizing soket head cap screw After move;Stepper motor 501 crosses shaft coupling 503 and drives the lead screw of ball guide screw nat 507 to rotate and then drive rolling above Pearl nut, which moves left and right, realizes that soket head cap screw moves up and down.Because the ball-screw apparatus of Z axis is in vertical position, and Ball-screw nut 507 cannot be self-locking, so needing anti-reverse measure, what the design selected is freewheel clutch 5063.Because The design prevents ball nut from moving down, so preventing from reversing using an one-way clutch 5063 and a friction plate 5064 Dynamic, wherein thrust ball bearing 5062, which is located above friction plate 5064, uses sleeve connection between them, friction plate 5064, which is close to, to be surmounted Clutch 5063, freewheel clutch 5063 on deep groove ball bearing 5061, fixed by end cap by deep groove ball bearing 5061.
The lock of automatic tapping machine is paid to be realized using electric screwdriver equipment series 4, and structure includes: connecting plate 401, uniaxial lock Countercylinder support plate 402, uniaxial lock countercylinder 403, straight-line rolling guide set 404, electric screwdriver support plate 405, electric screwdriver 406, buffering Spring 407, electric screwdriver collet support frame 408, electric screwdriver collet locking nut 409 and electric screwdriver collet 410.Wherein connecting plate 401 passes through It is bolted on the spherical guide of the ball-screw nut for being fixed on ball guide screw nat 507 and straight-line rolling guide set 508. Single shaft lock countercylinder support plate 402, straight-line rolling guide set 404 and electric screwdriver collet support frame 408 are fixed on connecting plate 401, Electric screwdriver support plate 405 is fixed on the spherical guide of straight-line rolling guide set 404, and single shaft lock countercylinder 403 is fixed on uniaxial lock In countercylinder support plate 402, electric screwdriver 406 is fixed in electric screwdriver support plate 405, and buffer spring 407 and electric screwdriver collet 410 are fixed on On electric screwdriver collet support frame 408, and electric screwdriver collet 410 is locked by electric screwdriver collet locking nut 409.In the screwed lock when work During need electric screwdriver 406 to carry out the movement in reciprocal vertical direction, therefore uniaxial lock countercylinder 403 is selected to drive electric screwdriver 406 Movement, at low cost, the kind of drive of service life length, while realizing that the reciprocating motion of electric screwdriver support plate 405 is real in turn with buffer spring 407 Existing electric screwdriver 406 moves back and forth.
The positioning of workpiece and step up to realize using the fixed cylinder 609 of twin shaft and workbench 608.Because designed by the present invention The fixed cylinder 609 of the twin shaft that automatic locking screw machine uses has certain flexibility, so can also be more other than retarder end cap Change different workpiece.
For the master control system of automatic tapping machine using programmable controller, this controller reliability is high, is suitable for this Kind small automatic equipment, selects stepping motor as power source, and control mode uses opened loop control.PLC controls X, Y, Z The rotation of three stepper motors of three axis, to complete the work of soket head cap screw alignment threaded hole.In order to automatic lock spiral shell Silk machine tri- axis of X, Y, Z are protected during the motion, are limited to it, therefore have limit to open at X, Y, Z axis both ends It closes.The movement of control lock countercylinder, so that the lock for completing screw pays work.The movement of positioning cylinder is controlled, is completed to workpiece clamp Tightly, the work unclamped.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc. With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this Within the protection scope of invention.
