Description

Thicknesser

The utility model relates to woodworking machinery.More clearly say so and be used for the thicknesser of woodwork planing operation.

Existing thicknesser version is various.For guaranteeing the size of planing workpiece, its height of table can be regulated.But most of adjustment processes are complicated, and it is bothersome to take a lot of work, and because of workbench is not a synchronization lifting for four jiaos, is difficult to leveling, also just do not guarantee the quality of workpiece planing.The replacing of existing thicknesser planing tool, clamping, adjustment mode are also simple and easy inadequately, and the adjustment precision of cutting edge is not high yet.In addition, present thicknesser workbench is all less, use inconvenient, also safety inadequately.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, and four jiaos of synchronization liftings when providing a kind of workbench to adjust can guarantee the parallel of workbench and planing tool, thereby guarantees the quality of work piece; And when regulating easily, simply, efficiently; The dismounting of planing tool, reset, clamp, adjust also simple, reliably; Workbench can be expanded greatly, and the angle of expanding surface can be finely tuned; The feed speed of planing is also adjustable, the thicknesser that the machining accuracy of complete machine is high.

In order to achieve the above object, the utility model thicknesser is by base, be installed in the frame on the base, be installed in the motor in the frame, be installed in the drive pulley on the motor, rack-mounted adjustable for height workbench, be installed in the height adjustment mechanism on frame and the workbench, be installed in two cylinders on the workbench, rack-mounted planing platform, be installed in the main shaft that has planing tool on the planing platform, be installed in the driven pulley of main shaft side, be installed in the driving belt on the moving belt pulley of principal and subordinate, being installed in the chain drive with main shaft drives that end beaming and guide shaft and be installed in planing platform side of planing on the platform is constituted.The height adjustment mechanism of workbench is by being installed in four jiaos of pedestals that have guide pin bushing on the frame, 4 guides of belt length groove in the middle of being fixed on the guide pin bushing, be installed in the active leading screw of band keyway in upper end in the guide, be installed in the driven leading screw in all the other 3 guides, be connected to the initiatively worm gear of leading screw upper end, be fixed on the worm and gear seat at angle in the planing that is installed in 4 guide upper ends, be installed in the worm and gear seat and the worm gear engaged worm, be fixed on the handwheel of worm screw end, be installed in 4 rhizoid thick sticks middle parts and have the holder that can from elongated slot, stretch out so as to 4 nuts fastening with workbench, be installed in 4 sprocket wheels of 4 rhizoid thick stick lower ends, be installed in the adjustable tensioner arm on the base bottom surface, be installed in the tightener sprocket of tensioner arm one end, installation is engaged on the chain that is positioned on 4 sprocket wheels and the tightener sprocket below the pedestal and constitutes.

During use, shake handwheel, just can drive worm screw, worm gear, active leading screw, sprocket wheel, chain successively and then drive all the other 3 driven screw mandrels and rotate.The so synchronous rotation of 4 rhizoid bars forces 4 nuts being installed on leading screw elongated slot synchronization lifting along guide.4 final workbench of fixing on it that drive of nut make its four jiaos of synchronization liftings.Thereby guarantee that workbench keeps parallel, the quality that guarantees work piece with planing tool at any time.This structure has improved the machining accuracy of complete machine.

So that secured adjusted mechanism is uniform 3 planing tools are installed on the main shaft.The secured adjusted mechanism of each planing tool is made up of two adjustment screw that are pressed on press strip on the planing tool, are installed in 3～6 screws of the upper knife groove that is arranged in main shaft on the press strip, two screw heads being installed in upper knife groove withstand the planing tool bottom surface.Two screw fronts of each upper knife groove are the spiral shell tool bore.During adjusting, straddle on the cylindrical of main shaft, the leveling ruler of the toolsetting device of riding is leaned against on the blade of planing tool with the toolsetting device of riding.When blade not at ordinary times, gently turn round adjustment screw with the spiral shell cutter, its head ejected or throw off planing tool, be flattened on the leveling ruler until the whole blade of planing tool, tighten screw again and get final product.Regulate simply, fast, reliable clamping, it is extremely convenient to dismantle.

Workbench all is installed with Material and article holding frame with screw and jackscrew on the forward and backward two sides.It is made of support body, the fulcrum that is installed in support body two arm front ends, the cylinder that is sleeved on the fulcrum.During use, processed timber places on the Material and article holding frame, and is very convenient.It has expanded the actual usable floor area of workbench greatly.Transfer in or access jackscrew, the angle of fine-tuning Material and article holding frame makes it consistent with table plane.

Chain drive is the chain drive of fork type secondary gear reducer transmission.It makes guide shaft that two kinds of rotating speeds be arranged, and makes the feed speed of timber have two kinds, to adapt to the different requirements of different workpieces.

4 holders that 3 band transverse holes are installed above the guide hole of guide are installed on the planing platform, are also had transverse holes on the aforesaid worm and gear seat.One rod respectively is installed in preceding two and latter two in 4 transverse holes.Prop up rod and can make handrail usefulness, also can be used for protection or lift to move and move the utility model.

Task of the present utility model comes to this and finishes.

But four jiaos of synchronization lifting adjustment of workbench of the present utility model have improved the planing operation quality and the machining accuracy of workpiece, have guaranteed the parallel of workbench and planing tool.Easily laborsaving, convenient and swift when regulating lifting.The dismounting of planing tool, replacing, clamping, leveling are simple, reliable, precision is high.Workbench can have Material and article holding frame, and can finely tune, and is easy to use.The feed speed of planing is adjustable, to adapt to the difference processing needs of different workpieces.Compare with the like product in past, its workbench is adjusted the time can save 20～70%.It can be widely used in the thicknesser processing of woodwork.
