Abstract
The utility model relates to a screw rod and nut lifting device for small woodworking machines, and comprises the screw rod connected an elevated bench and the nut fixed at one side of machine body. The lower end of the screw rod is provided with a ratchet wheel whose outer part is sheathed with a handle provided with a through hole. A pin shaft is arranged in the through hole. One side of the pin shaft facing the ratchet pawl is provided with a ratchet pawl, and the other side of the pin shaft is provided with a reversing positioning groove. The utility model can lengthen the handle because of the adaption of a ratchet wheel and ratchet pawl mechanism, can have the advantages of convenient operation and use, fast speed of rise and fall and high work efficiency, and can be suitable for rise and fall of the saw table and tongue groove workbench of the small woodworking machines.
Description
The utility model relates to a kind of woodworking machinery, specifically a kind of small-sized woodworking machine screw mandrel screw lowering or hoisting gear.
We know, small-sized woodworking machine can be used for plane, saw, tongue-and-groove etc., have obtained being extensive use of at aspects such as Wood Processing, furniture manufacturings.At present, the lowering or hoisting gear of its buck and tongue-and-groove worktable mainly adopts following several mode: the one, and gear, rackwork utilize lifter wheel to move lifting buck or tongue-and-groove worktable along tooth bar is upper and lower; The 2nd, screw mandrel screw elevator mechanism utilizes screw mandrel along the upper and lower realization lifting of moving of screw, and usually the screw mandrel bottom connects a handle with sleeve, owing to be subjected to the restriction of body and worktable, handle with sleeve processing can not be oversize, it drives screw mandrel and rotates inconveniently, wastes time and energy, work efficiency is low; Also utilize the spiral cam lifting, it processes more complicated, cost height.
The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned screw mandrel screw elevator mechanism, a kind of simple in structure, easy processing, easy for operation to be provided, the small-sized woodworking machine screw mandrel screw lowering or hoisting gear that rising or falling speed is fast, work efficiency is high, cost is low.
For achieving the above object, a kind of small-sized woodworking machine screw mandrel screw lowering or hoisting gear, it includes screw mandrel that connects self-powered platform and the screw that is fixed on body one side, it is characterized in that the screw mandrel lower end is provided with a ratchet, the outer sheathed one handle of ratchet, handle is provided with a through hole, in a bearing pin is housed, bearing pin is provided with ratchet towards a side of ratchet, and opposite side is provided with the commutation locating slot.
The utility model is owing to adopt ratchet, pawl structures on screw mandrel lower end and the handle, can realize the lifting of worktable by shaking handle, decreased food can not be subjected to the restrictions of object on every side such as body like this, that can process compared to existing technology is longer, easy for operation, rising or falling speed is accelerated, the work efficiency height.It is applicable to the lifting of small-sized woodworking machine buck or tongue-and-groove worktable.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model structural representation, Fig. 2 be among Fig. 1 A-A to schematic representation.
From Fig. 1, Fig. 2, can find out, a kind of small-sized woodworking machine screw mandrel screw lowering or hoisting gear, it is provided with screw mandrel 1, screw 2.Screw mandrel 1 top connects self-powered platform by bearing pin, and self-powered platform can be a buck, also can be the tongue-and-groove worktable.Screw 2 is fixed on body one side, and screw mandrel 1 can be along screw 2 upper and lower liftings, and then drives the lifting of worktable.The utility model screw mandrel 1 lower end is provided with a ratchet 3, and it is two-way.Ratchet 3 can directly process in screw mandrel 1 bottom, also can be set on the screw mandrel 1 as component.The outer cover of ratchet 3 is provided with one handle 4, and handle 4 lower ends are provided with a back-up ring 5.The utility model handle 4 inboards are provided with a through hole along the tangent line of ratchet 3, one bearing pin 6 is housed in the through hole, and bearing pin 6 is provided with ratchet towards a side of ratchet 3, and opposite side is provided with two commutation locating slots, corresponding locating slot is provided with stage clip 7 and steel ball 8 in the handle, to prevent commutate bearing pin slippage or dislocation.The transposition locating slot is used for fixing the position of bearing pin, and the ratchet on it is cooperated with two-way ratchet 3, by back and forth shaking handle, and the liter of realization screw mandrel or fall.
During use, according to the lifting needs, promote commutation bearing pin 6, selected lifting locating slot back and forth shakes the lifting that handle can be realized the worktable requirement.The handle that the utility model handle is compared existing screw mandrel screw elevator mechanism extends greatly, and it is easy for operation, laborsaving, work efficiency is high.The utility model is simple and reasonable for structure, cost is low is a kind of desirable small-sized woodworking machine screw mandrel screw lowering or hoisting gear, is suitable for the lifting of small-sized woodworking machine buck or tongue-and-groove worktable.
