Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, further set forth below in conjunction with concrete diagram.
Fig. 1 is the structural representation of one embodiment of the invention, comprise a platform base 4, platform base 4 one sides are provided with stepless locking mechanism 5, stepless locking mechanism 5 is supported by the latch mechanism support 6 being fixed on platform base 4, the opposite side of platform base 4 is provided with feeding module 2, and the top of feeding module 2 is fixed with processing module 3.
As shown in Figure 3, stepless locking mechanism 5 comprises four-bar mechanism 5.2, the bottom of four-bar mechanism 5.2 is provided with handle 5.1, the top of four-bar mechanism 5.2 is provided with brake disc 5.3, in the middle of brake disc 5.3, be provided with through hole, in through hole, be installed with rotating shaft 5.4, rotating shaft 5.4 is connected with described latch mechanism support 6 by bearing.This mechanism utilizes the dead-centre position of four-bar mechanism 5.2, is rotating to definite position, reaches self-locking state by upwards pulling handle 5.1, compresses brake disc 5.3, the location of realizing rotating shaft 5.4.Need to adjust time, pull lower handle 5.1 and can remove locking, thereby ensure freely adjusting of rotating shaft 5.4.
Rotating shaft is connected with fixture 1 near a side of processing module, and fixture 1 as shown in Figure 2, comprises chuck, and chuck is provided with claw 1.3, and claw 1.3 is driven by the bevel gear 1.2 being provided with in chuck by chuck handle 1.1.In the time of rotating chuck spanner 1.1, drive chuck inner cone gear 1.2 rotates, thereby drives the claw 1.3 of chuck to link, and realizes for the centering of blank and clamping.The present embodiment adopts adjustable four-jaw chuck centering clamping mode, can realize the clamping for difformity blank.
