Turnover machine

Technical field

The present invention relates to plate and make the field, especially about a kind of turnover machine that is applied to the plate manufacturing line.

Background technology

As shown in Figures 1 and 2, existing turnover machine comprises frame 50, axle drive shaft 51, motor 52, rotating disk 53 and fork arm 54.These axle drive shaft 51 levels are installed on this frame 50 and by motor 52 and drive, this rotating disk 53 has two, and be vertically mounted on respectively this driving, 51 two ends, on two rotating disks 53 fork arm 54 is installed all, during motor 52 work, it drives the fork arm 54 that is fixed on this rotating disk 53 by axle drive shaft 51 and rotates, and namely the path of motion of fork arm 54 is a whole circle.But, this kind turnover machine has following shortcoming: the path of motion of fork arm is a whole circle, make the operating altitude of whole turnover machine high, but on manufacturing line, the operating altitude of pressing plate can not be on sustained height, the high potential difference of a blanking of needs that has, thus the hole that sinks need to be dug on the ground, thus cause: 1) infrastructure investment is large; 2) installation period is long; 3) for the enterprise of technological transformation, can affect normal production; 4) there is the hole of sinking to be difficult for the site clearing, ground required high; 5) power plant is many, and equipment investment is large, and power consumption is high.

Summary of the invention

Technical matters to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of turnover machine that can effectively reduce operating altitude is provided.

The technical solution adopted for the present invention to solve the technical problems is: a kind of turnover machine comprises that frame, rotating mechanism, travel mechanism reach at least quadruplet fork arm, rotation and the equal level of travel mechanism are installed on the frame, when two fork arms from advancing the plate of Board position clamping, after rotating mechanism turns 180 °, two fork arms drive through travel mechanism, be pushed back the former Board position that advances, reach the purpose of two fork arm circulation clamping plates and turn-over, because fork arm only rotates at the upper half-turn of turnover machine, reduced the operating altitude of turnover machine.

The rotating mechanism of described turnover machine comprises device of rotation driving, at least two rotating disks, rotating shafts and organizes shifting roller more to have at least two rotating disks to be fixed on the rotating shaft two ends, and support all is installed each rotating disk and the constraint fork arm carries out straight-line shifting roller.

The fork arm of described turnover machine comprises square type pipe, mobile rack, synchronous tooth bar and thrust roller, and being positioned at upper and lower y-bend pole pair should upper and lower side install mobile rack, and lateral surface is all installed synchronous tooth bar, and the thrust roller is installed in the both ends of each fork arm.

The travel mechanism of described turnover machine comprises mobile drive deivce, traveling gear, transmission shaft and at least two pairs of synchronizer gears, at least two pairs of coaxial connections of synchronizer gear, synchronous tooth bar with upper and lower two fork arm lateral surfaces meshes respectively, be vertically mounted in the rotating shaft, when the traveling gear of travel mechanism rotates, drive is positioned at the mobile rack traveling priority of lower wishbone downside, under the effect of synchronizer gear tooth bar, makes to be positioned at also equidirectional synchronizing moving of upper wishbone.

The frame of described turnover machine comprises support, thrust arc plate, the thrust arc plate is placed in the bottom that is positioned at upper and lower fork arm same plane, when upper and lower fork arm when the upper half-turn of turnover machine rotates, the thrust roller of upper and lower fork arm one end rolls at the thrust arc plate, stops upper and lower fork arm to glide.

The invention has the beneficial effects as follows: when two fork arms from advancing the plate of Board position clamping, after rotating mechanism turns 180 °, two fork arms drive through travel mechanism, be pushed back the former Board position that advances, reach the purpose of two fork arm circulation clamping plates and turn-over, because fork arm only rotates at the upper half-turn of turnover machine, reduced the operating altitude of turnover machine.
