The utility model discloses an adopt following technical scheme to realize:

a wood clamping device of a vertical wood splitting machine comprises a machine body, a hydraulic oil cylinder is fixed on the top of the machine body, the side wall of the machine body is connected with a sliding block in a sliding way, a riving knife is fixedly arranged on the sliding block, the top of the riving knife is fixedly connected with a piston rod of the hydraulic oil cylinder, a limiting plate is fixedly arranged on the outer side of the top of the riving knife, a wood positioning device is sleeved between the riving knife and the limiting plate, the wood positioning device comprises a retainer ring and two wood positioning claws which are respectively and rotationally connected with the front end and the rear end of the bottom of the retainer ring, the piston rod is vertically provided with an inner hexagon bolt, the end part of the inner hexagon bolt is embedded with a pressure lever, the bottom of the pressure lever is attached to the top of the wood positioning device, the front end and the rear end of the bottom of the pressure lever are respectively fixed with a baffle, and the two baffles are respectively positioned at the front end and the rear end of the wood positioning device.

One end of the pressing rod, which is far away from the machine body, is sleeved with a handle, and the handle is provided with anti-skid grains.

And the inner hexagon bolt is sleeved with a locknut.

The utility model has the advantages that:

the utility model discloses simple structure, convenient operation can effectively carry out the centre gripping to timber, need not the manual work and holds up the wood, has reduced staff's intensity of labour, has improved work efficiency, has also improved the security of splitting wood work.

fig. 4 is a schematic structural view of the wood positioning device.

In the figure: 1. the wood positioning device comprises a machine body, 2, a sliding block, 3, a piston rod, 4, a limiting plate, 5, a hydraulic oil cylinder, 6, an inner hexagon bolt, 7, a locknut, 8, a wood positioning device, 81, a retaining ring, 82, a wood positioning claw, 9, a riving knife, 10, a pressure rod, 11, a baffle, 12 and a handle.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

the wood clamping device of the vertical log splitter as shown in fig. 1-4 comprises a machine body 1, a hydraulic oil cylinder 5 is fixed at the top of the machine body 1, a slide block 2 is slidably connected with the side wall of the machine body 1, a riving knife 9 is fixedly installed on the slide block 2, the top of the riving knife 9 is fixedly connected with a piston rod 3 of the hydraulic oil cylinder 5, a limit plate 4 is fixedly installed at the outer side of the top of the riving knife 9, a wood positioning device 8 is sleeved between the riving knife 9 and the limit plate 4, the wood positioning device 8 comprises a retaining ring 81 and two wood positioning claws 82, the two wood positioning claws 82 are respectively and rotatably connected with the front end and the rear end of the bottom of the retaining ring 81, an inner hexagonal bolt 6 is vertically installed on the piston rod 3, the inner hexagonal bolt 6 adopts an M10 x 65 inner hexagonal bolt, a press rod 10 is embedded in the end of the inner hexagonal, two baffles 11 are respectively positioned at the front end and the rear end of the wood positioning device 8.

One end of the pressure lever 10 far away from the machine body 1 is sleeved with a handle 12, and the handle 12 is provided with anti-skid grains.

The inner hexagon bolt 6 is sleeved with a locknut 7, and the locknut 7 adopts an M10 hexagon locknut.

The working principle is as follows: starting the machine, moving the riving knife 9 downwards to a position about 2-3 mm above the round timber at the speed V, inserting the timber positioning device 8 onto the riving knife 9, and enabling the claw tip of the timber positioning claw 82 to be in contact with the end part of the round timber. One end of a compression bar 10 is embedded into the end part of a M10 x 65 hexagon socket head cap screw 6, a force F acts on the end part of a handle 12 of the compression bar 10, a downward acting force F1 is generated on a wood positioning claw 82 of a wood positioning device 8 under the action of the force F1, the wood positioning claw 82 moves downwards and is deeply positioned in round wood (the depth is about 10mm), the round wood cannot swing left and right, and the two wood positioning claws 82 are also restricted by two limiting plates 4 welded on a riving knife 9 and cannot move back and forth, so that the wood is clamped. When the wood is split downwards by the riving knife, the wood is split from the center, the two wood positioning claws 82 start to rotate and separate towards two sides by taking the retainer ring 81 as the center, when the wood is split to a certain position, the two wood positioning claws 82 are separated from the wood, at this time, the movement of the riving knife can be stopped, then the wood positioning device 8 is taken back, the riving knife is placed at a safe position, and the unfinished wood splitting action is continued.
