Embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
As shown in Figure 1 and Figure 2, horizontal tensile testing machine of the present invention comprises the Working gantry 1 of a strip, and Working gantry 1 top is shaped grooved, on two sides of groove, each side all is equipped with track 2, for the purpose of firm, in each side upper and lower two tracks 2 can be installed.The position of staggering attachment rail 2 also offers several pinned holes 3 on the side.One end of Working gantry 1 is set at loading end, is provided with oil cylinder main body 4 at loading end, oil cylinder main body 4 is connecting headstock 5, and headstock 5 is placed on the track 2.Also be placed with simultaneously in the rear end of track 2 and move freely formula tailstock 6, tailstock 6 has three groups of actuating units based on tailstock body on tailstock body, and one group is travel mechanism, and one group is locking mechanism, and also having one group is micro-adjusting mechanism.These mechanisms all control by remote measuring and controlling system.
Shown in Fig. 3～5, travel mechanism comprises a drive motor 7, and drive motor 7 is installed in the end of tailstock body, and the output terminal of drive motor 7 connects one speed reducer, drives pulley 9 by intermediate transmission mechanism on speed reduction unit drive link 8.Pulley 9 is installed in two sides of tailstock body, can be two-wheeled mechanism, four wheel mechanism, perhaps eight wheel mechanisms, its corresponding track 2 and being provided with, when having upper and lower two when one-sided track 2, the pulley of installing on tailstock body just can be four groups eight, two upper and lower layouts of pulley of each group are slidingly installed on the track 2.Two groups is driving wheel in these the four groups wheels, drive by speed reduction unit drive link 8 and intermediate transmission mechanism, intermediate transmission mechanism can be chain transmission, also can be band transmission, gear drive, be in particular: two described pulleys 9 that belong to two groups of driving wheels respectively are installed at the two ends of speed reduction unit drive link 8, and drive link 8 drives another one pulley in each driving wheel by two chain drives respectively again; In four groups of wheels in addition two groups be engaged wheel, two groups of engaged wheels independently slide at the drive lower edge of driving wheel track 2, the driven wheel cooperation makes tailstock 6 produce certain displacement in orbit.
The orbital plane of the upper and lower two-layer track in the foregoing description is oppositely arranged, and makes pulley all be positioned at the inboard of two tracks, like this, in the time of slip, also can anti-deviation and anti-jolting.
Locking mechanism has two groups, is arranged symmetrically in the both sides of tailstock body.Each group all comprises a lock out motor 10, and the output terminal of lock out motor 10 connects one speed reducer, connects a screw rod 11 that crosses out outside the tailstock body on the speed reduction unit drive link.By the slide block 12 that is threaded, symmetry is installed two latches 13 on the slide block 12 on the screw rod 11.Latch 13 can be corresponding with each pinned hole 3 position of offering on the Working gantry side.
At tailstock body front end or rear end the one stroke switch is installed also, in the time of in tailstock moves to preset range, when travel switch was sensed the spacer pin that plugs in advance on the Working gantry, travel switch was just given control system with signal feedback, and control system will instruct drive motor 7 to quit work.Behind mobile the stopping, control system will instruct lock out motor 10 to start, the locking mechanism action.After lock out motor 10 started, because the rotation of screw rod 11 can drive slide block 12 telescopic movings, so the latch 13 of both sides can stretch out, and is inserted in the pinned hole 3 on the Working gantry.When latch 13 enters into the process of pinned hole 3, change owing to can produce great electric current, therefore by control, can judge the position of latch 13 to electric current.When latch 13 ran to extreme position, because current of electric is excessive, lock out motor 10 was moved with regard to corresponding stopping, and promptly finishes locking work.
Micro-adjusting mechanism refers to, top or bottom (generally being mounted in the top) at tailstock body, one fine setting motor 14 is installed, the output terminal of fine setting motor 14 connects a runner 15 through speed reduction unit, or belt wheel, sprocket wheel, gear set, engaged wheel center pit in runner or belt wheel, sprocket wheel, the gear set is a threaded hole, wears a screw rod 16 in the threaded hole.17 (as shown in Figure 3) of front end connection tailstock anchor clamps of screw rod 16.
Micro-adjusting mechanism plays moving and stops, after locking is finished, and the effect that tailstock is finely tuned.It looks the length of test insulator, starts fine setting motor 14, and drive screw rod 16 stretching tailstock anchor clamps 17 advance or retreat, and find the accurate position of insulator, then chucking.
The present invention adopts portable tailstock, comprises the mechanism that mobile power is provided on this tailstock, is used for fixing the latch of position and carrying, the tailstock anchor clamps that are used to finely tune.Tailstock is equipped with on the track that pulley is placed on horizontal puller system Working gantry 1, when the mobile tailstock of needs, starter motor drives pulley and rotates, move to desired location, starting latch mechanism then is inserted into four steel latches on the tailstock in the pinned hole on the Working gantry 1, be used for fixing tailstock, the tensile load when bearing test.
