Abstract
The utility model provides a clamping and expanding synchronous mechanism for a two-dimensional and three-dimensional feeding device, comprising a first clamp and a second clamp in cooperation and a left rotation screw rod and a right rotation screw rod axially connected and disposed on the frame, a first sliding block is disposed on the right rotation screw rod via an internal screw thread sleeve, a second sliding block is disposed on the left rotation screw rod via an internal screw thread sleeve, the first clamp is disposed on the first sliding block, and the second clamp is disposed on the second sliding block. The frame is also provided with a servo motor, a first belt wheel is disposed on an output shaft of the servo motor, a second belt wheel is disposed on the left rotation screw rod or the right rotation screw rod, the first belt wheel is connected with the second belt wheel via a synchronous belt. When the servo motor drives the left rotation screw rod or the right rotation screw rod to rotate simultaneously, the first clamp and the second clamp simultaneously perform a face-to-face movement or a back-to-back movement for clamping or releasing a clamped object. The clamping and expanding synchronous mechanism in the utility model is characterized by simple and reasonable structure, flexible operation, low manufacture cost, and wide application scope.
Description
Technical field
That the utility model relates to is a kind of two, the clamping of the servo pay-off of three-D, open lazy-tongs, particularly the peripheral automatic mechanism of metal forming machinery.
Background technology
Chinese patent document number CN 2666660Y discloses a kind of hitch feed mechanism on December 29th, 2004, and hitch feed mechanism comprises fuselage, power transmission shaft, cycloidal cam, roller, slide block, slide bar, clamping bar and anchor clamps; Cycloidal cam is fixed on the power transmission shaft, and said slide block has two, and two slide block relative fixed also are arranged at the left and right sides of cycloidal cam respectively, and two slide blocks are provided with roller, and said roller contacts with cycloidal cam; Each slide block is equipped with fairlead in both sides up and down, and fairlead is socketed on the guide post, guide post and fuselage relative fixed; Clamping bar and slide block relative fixed; Said clamping bar has two; Be provided with some anchor clamps between said two clamping bars; Spacing between the adjacent anchor clamps equals maximum radius and least radius poor of cycloidal cam, and each anchor clamps comprises the last collet and following collet that cooperatively interacts, and last collet, time collet are arranged at respectively on two clamping bars.The complex structure of this hitch feed mechanism, cost of manufacture is higher, makes the user not too satisfied.
The utility model content
The purpose of the utility model aim to provide a kind of simple and reasonable, flexible operation, cost of manufacture low, applied widely two, the clamping of the servo pay-off of three-D, open lazy-tongs, to overcome weak point of the prior art.
By the clamping of a kind of two, the servo pay-off of three-D of this purpose design, open lazy-tongs; Comprise first folder and second folder that cooperatively interact; Its architectural feature is also to comprise left-handed screw mandrel that axially joins and the dextrorotation screw mandrel that is arranged on the frame, and first slide block is located on the dextrorotation screw mandrel through inner screw sheath, and second slide block is located on the left-handed screw mandrel through inner screw sheath; First folder is arranged on first slide block, and second folder is arranged on second slide block.
Also be provided with servomotor on the said frame, first belt wheel is arranged on the output shaft of servomotor, and second belt wheel is arranged on left-handed screw mandrel or the dextrorotation screw mandrel, and first belt wheel joins through the synchronous band and second belt wheel.
After the utility model adopted above-mentioned technical scheme, when servomotor drove left-handed screw mandrel and rotates simultaneously with the dextrorotation screw mandrel, first folder and second folder just simultaneously in opposite directions or motion dorsad, were used for clamping or relieving gripped object.Because the employing servomotor so can collect information through encoder, is accurately controlled the position of first folder and second folder by control centre through servomotor then, thereby is clamped accurately or open action.
The utlity model has simple and reasonable, flexible operation, low, the advantage of wide range of application of cost of manufacture.
Description of drawings
Fig. 1 is the utility model one example structure sketch map.
Among the figure: 1 is first folder, and 2.1 are the dextrorotation screw mandrel, and 2.2 is left-handed screw mandrel, and 3 is second folder, and 4 is second slide block, and 5 is second belt wheel, and 6 is to be with synchronously, and 7 is first belt wheel, and 8 is servomotor, and 9 is first slide block, and 10 is frame.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1; This two, the clamping of the servo pay-off of three-D, open lazy-tongs; Comprise that first folder, 1 and second folder 3 that cooperatively interacts and the left-handed screw mandrel that axially joins 2.2 that is arranged on the frame 10 are located on the dextrorotation screw mandrel 2.1 through inner screw sheath with dextrorotation screw mandrel 2.1, the first slide blocks 9, second slide block 4 is located on the left-handed screw mandrel 2.2 through inner screw sheath; First folder 1 is arranged on first slide block 9, and second folder 3 is arranged on second slide block 4.
Also be provided with servomotor 8, the first belt wheels 7 on the frame 10 and be arranged on the output shaft of servomotor 8, second belt wheel 5 is arranged on left-handed screw mandrel 2.2 or the dextrorotation screw mandrel 2.1, and first belt wheel 7 joins through being with 6 and second belt wheel 5 synchronously.
The clamping of above-mentioned two, the servo pay-off of three-D, open lazy-tongs and can be used as a unit; On the numerically controlled lathe two such unit can be set; The encoder of servomotor in two unit through the synchronous usefulness of same control centre obtains same signal and sends same action; Drive left-handed screw mandrel 2.2 through synchronous band again and rotate, thereby clamped accurately and open action with dextrorotation screw mandrel 2.1.
