Detailed description of the invention
Below in conjunction with specific embodiment, a kind of pull bar driver train eliminating friction stress of the present utility model is further described.
As shown in Figure 1, a kind of pull bar driver train eliminating friction stress, comprise actuating device, contiguous block 3 and pipe link, described actuating device is provided with the rocking arm 2 be rotatably connected with it, described pipe link comprises head rod 4.1 and the second pipe link 4.2, the top of described contiguous block 3 and the front end of described head rod 4.1 are fixed, bottom and the described rocking arm 2 of described contiguous block 3 are hinged, rear end and the bar body 8 of described second pipe link 4.2 are fixed, the front end of described head rod 4.1 rear end and the second pipe link 4.2 is hinged by latch 6, the rear end of described head rod 4.1 and the front end of the second pipe link 4.2 are provided with connecting arm 5 in hinged place, one end of described connecting arm 5 is hinged with the front end of described head rod 4.1 rear end and the second pipe link 4.2 by described latch 6, the other end and the bearing 7 of described connecting arm 5 are rotatably connected.Like this, by the swing of rocking arm 2 be rotatably connected with actuating device, and then, the crank motion that head rod 4.1 is done along fore-and-aft direction is driven by contiguous block 3, hinged by with the second pipe link 4.2 of head rod 4.1, and then drive the second pipe link 4.2 and bar body 8 along the crank motion of fore-and-aft direction, thus complete the conveying of bar body 8 pairs of load-transfer devices.Wherein, hinged by with the second pipe link 4.2 of head rod 4.1, like this, the application force of rocking arm 2 and contiguous block 3 pairs of head rods 4.1 and the second pipe link 4.2 due to hinged effect along the length direction transmission of bar body 8.And the firm access node structure of head rod 4.1 of the prior art and the second pipe link 4.2 makes rocking arm 2 and the application force of contiguous block 3 to the second pipe link 4.2 be perpendicular to the length direction of bar body 8, like this, the application force of vertical second pipe link 4.2 can produce shearing stress at the second pipe link 4.2 with the connection location of bar body 8, thus causes bar body 8 and the second pipe link 4.2 to rupture.Therefore, compared with firm access node structure of the prior art, hinged by with the second pipe link 4.2 of head rod 4.1, eliminate the application force perpendicular to the second pipe link 4.2 direction, and then the shearing stress eliminated between the second pipe link 4.2 and bar body 8, and ensure that bar body 8 is not subject to the effect of friction stress in reciprocatory movement, ensure that the validity of motion.Simultaneously, head rod 4.1 and the second pipe link 4.2 have been provided with connecting arm 5 in hinged place, connecting arm 5 can play the effect of auxiliary transmission to the crank motion of head rod 4.1 and the second pipe link 4.2, avoid head rod 4.1 and the second pipe link 4.2 long, concussion in Movement transmit process, makes the driving of the second pipe link 4.2 pairs of bar bodies 8 more steadily reliable.
See accompanying drawing 1, the rear end of described second pipe link 4.2 is provided with tapped bore, and the end of described bar body 8 is provided with outside thread, and described bar body detachably to be fixed with described second pipe link 4.2 by being spirally connected of outside thread and tapped bore.Like this, due to the outside thread of bar body 8 and being spirally connected of tapped bore, bar body 8 and the second pipe link 4.2 detachably being fixed, is convenient to change bar body 8 at any time, reduces productive costs; Meanwhile, also by tapped bore, the second pipe link 4.2 can be connected different parts, expand Applicable scope.Preferred technical scheme can be further: described actuating device is servomotor 1.Like this, the comformability of servomotor 1 and stability are stronger, can rocking arm 2 be driven to move by pulsation-free, and then drive the motion of the second pipe link 4.2 and bar body 8.
Above-mentionedly only a kind of specific embodiment in the utility model to be illustrated; but can not as protection domain of the present utility model; every equivalence made according to the design spirit in the utility model changes or modifies, and all should think and fall into protection domain of the present utility model.
