Description

The last horizontal cutter shaft planker lowering or hoisting gear of carpenter's four side moulder

Technical field

The utility model relates to a kind of carpenter's four side moulder, especially the last horizontal cutter shaft planker lowering or hoisting gear of carpenter's four side moulder.

Background technology

The woodworking machinery on general dressed timber surface, in order to make the timber rear surface of scraping more smooth and thickness is accurate, all be provided with force plane and trying plane two procedures, this two procedures all must be according to the thickness of timber before processing, adjust the upper and lower position of horizontal planing tool on it, and generally use in the market following two kinds of woodworking machinerys are arranged:

A kind of is to adjust the cutter lifting with manual mode, cutter is to be contained on the elevating bracket, these elevating bracket central authorities are provided with a pivot hole of running through, the pivot hole is provided with internal thread, internal thread cooperates with a screw rod elevating bracket is journaled on the screw rod, the other end of screw rod is by the external handgrip of gear-box, rotary handle can drive the screw rod rotation and elevating bracket is moved on screw rod, manually adjust the height and position of woodworking machinery cutter thus, but this manual adjustment mode, location effort, consuming time, its size is difficult to control and the use that can't match with automated machine.

And another kind is to adopt the woodworking machinery of automation to process, above-mentioned screw rod one end is installed a gear-box, utilize the gear driven screw rod in the gear-box, the motor of one driving gearbox is installed in a side of gear-box again, thereby both can carry out manual adjustments, driven rotary can automatically adjust again, but there is following shortcoming in it: 1), because worm screw is by the direct drive screw of worm gear in the manual adjustments middle gear case, thereby when adopting apparatus for automatically lifting, along with driving elevating bracket, the rotation of screw rod moves, rotate but also can drive worm screw simultaneously, the handle of being located on the worm screw is rotated, so, during the motor operation, handle is wrapped in operator's clothing on the handle easily, and causes unexpected generation, and its security is relatively poor; 2), because motor is installed on the bottom of screw rod, motor can not followed the lifting of the base of tool and lifting, thereby the wood chip during work on the base of tool often is scattered and is deposited on the lifting motor, thereby has influence on the regular event of motor, even damages described motor.

The utility model content

In order to solve the defective that exists in the above-mentioned prior art, the utility model provides the cutter shaft planker lowering or hoisting gear of carpenter's four side moulder of a kind of simple in structure, working stability, safety and motor long service life.

The technical solution of the utility model is: the last horizontal cutter shaft planker lowering or hoisting gear of carpenter's four side moulder, on screw mandrel, be provided with the cutter shaft planker, be fixed with on the screw mandrel of cutter shaft planker lower end can with the synchronous following worm gear of rotation of screw mandrel, following worm gear is by worm screw drive down, the end of following worm screw is provided with manual control lever, be fixed with gearbox on the described cutter shaft planker, be provided with spiral sleeve in the last gearbox, screw mandrel passes the described axle sleeve of going up in the gearbox, described axle sleeve is fixed with the last worm gear of doing elevating movement along screw mandrel outward, last worm gear is arranged on worm screw, and last worm screw is the input of last gearbox and is connected with motor.

Described gearbox is fixed on the cutter shaft planker, and screw mandrel is provided with bearing block, and bearing block is fixed on the cutter shaft planker.

The two ends of described Upper shaft sleeve are respectively equipped with bearing, and its bearing fixing is in last gearbox.

Described cutter shaft planker is provided with mounting groove, and last gearbox is fixed in the mounting groove.

The beneficial effects of the utility model are: 1), since screw mandrel on last gearbox in be provided with spiral sleeve, and described axle sleeve is fixed with outward and can makes it make the moving last worm gear of lifting along screw mandrel, motor and the described gearbox of going up articulate, therefore, when adopting apparatus for automatically lifting, because gearbox makes the axle sleeve generation rotation in the gearbox and do lifting along screw mandrel moving on the motor-driven, and screw mandrel is not sent out rotation, thereby commentaries on classics does not take place to move the manual gear case it under.2), be installed on the last gearbox of cutter shaft planker owing to motor, motor is followed the lifting of cutter shaft planker and lifting, thereby the wood chip when having avoided work on the base of tool often is scattered and is deposited on the lifting motor, make motor be able to regular event, thereby prolong the service life of motor.

Fig. 4 is that Fig. 1 screw mandrel reaches worm screw annexation schematic diagram down with following worm gear;

The specific embodiment

As shown in Figures 1 to 4: the last horizontal cutter shaft planker lowering or hoisting gear of carpenter's four side moulder, on screw mandrel 1, be provided with cutter shaft planker 2, be fixed with on the screw mandrel 1 of cutter shaft planker 2 lower ends can with the screw mandrel 1 following worm gear 3 of rotation synchronously, following worm gear 3 is by worm screw 4 drives down, the end of following worm screw 4 is provided with manual control lever 5, be fixed with gearbox 6 on the described cutter shaft planker 2, be provided with spiral sleeve 61 in the last gearbox 6, screw mandrel 1 passes the described axle sleeve of going up in the gearbox 6 61, the described axle sleeve 61 outer last worm gears 62 of doing elevating movement along screw mandrel 1 that are fixed with, last worm gear 62 is arranged on worm screw 63, and the input that last worm screw 63 is last gearbox 6 also is connected with motor 7.Last horizontal cutter shaft planker lowering or hoisting gear according to the described carpenter's four side moulder of claim 1 is characterized in that, the described gearbox 6 of going up is fixed on the cutter shaft planker 2, and screw mandrel 1 is provided with bearing block 8, and its bearing block is fixed on the cutter shaft planker 2.The two ends of described axle sleeve 61 are respectively equipped with bearing 66, and its bearing 66 is fixed in the gearbox 6.Described cutter shaft planker 2 is provided with mounting groove 11, and last gearbox 6 is fixed in the mounting groove 11.

Operation principle, when cutter shaft planker 2 uses electric up-down, as long as start the motor 7 on the cutter shaft planker 2, drive the interior last worm screw 63 of the last gearbox that is installed on the cutter shaft planker 26 by motor 7, go up worm screw 63 then and drive upward worm gear 62, thereby drive axle sleeve 61 rotation and liftings, the speed of an axle sleeve drive simultaneously cutter shaft planker 2 is done lifting under the situation that screw mandrel 1 does not rotate moving.And when converting manual operation to, need only and close motor 7 power supplys, pass through the manual manipulation bar 5 of rotary screw rod 1 lower end again, make manual manipulation bar 5 drive worm screw 4 down, utilize the following worm gear 3 that worm screw 4 drivings down are fixed on the screw mandrel that screw mandrel 1 is rotated again, thereby make the axle sleeve 61 in the gearbox 6 move up and down state, also drive cutter shaft planker 2 simultaneously by the axle sleeve 61 in the last gearbox 6 simultaneously and move up and down at the situation lower edge screw mandrel that does not rotate.
