Abstract

The utility model relates to a lifting mechanism for the movable working table of woodworking multipurpose machines. The utility model is mainly composed of a rack, a gear, a gear shaft, a handle, etc. The rack is vertically fixed on the wall of the middle position of the lower part of the movable working table. The gear shaft penetrates through the hole of the side wall of a machine body side wall and the hole of a fixed support seat. The inner end of the gear shaft is provided with the gear. The outer end of the gear shaft is provided with the handle. A spring is sheathed on the gear shaft between the gear and the fixed support seat. The gear and the rack are engaged. The utility model has the advantages of easy fabrication, high technique precision, high durability, fast lifting speed and stable lifting, and is used for small woodworking multipurpose machines.

Description

Carpenter's Do-All movable table elevating mechanism

The utility model relates to a kind of wood processing machinery, is a kind of carpenter's Do-All movable table elevating mechanism specifically.

At present, carpenter's Do-All movable table elevating mechanism generally adopts elevating screw, parts such as lifting handle and lifting screw are formed, the lifting screw is installed on the stationary work-table, elevating screw passes the lifting screw, and the one end is fixed on the movable table, and the other end is provided with lifting handle, rotate lifting handle, utilize moving up and down of elevating screw to realize the lifting of movable table.This elevating mechanism difficulty of processing is bigger, and each parts fit clearance is big, and technology acuracy is poor, and is fragile during use, and the movable table rising or falling speed is slow, the lifting shakiness.

The purpose of this utility model is exactly the shortcoming that overcomes existing movable table elevating mechanism, and a kind of easy processing is provided, and the technology acuracy height is durable, the movable table elevating mechanism that rising or falling speed is fast and lifting is stable.

For achieving the above object, a kind of carpenter's Do-All movable table elevating mechanism, it mainly is made up of tooth bar, gear, gear shaft and handle etc., it is characterized in that tooth bar vertically is fixed on the wall of movable table lower middle position, gear shaft passes hole on lathe bed one sidewall and the hole on the hold-down support, in gear shaft the inner gear is housed, and handle is equipped with in the gear shaft outer end, on the gear shaft between hold-down support and the gear, be arranged with spring, gear and tooth bar engagement.

The utility model has been owing to adopted the gear elevating mechanism, thereby makes the multi-purpose wood working machine tool good looking appearance, and the movable table elevating mechanism is easily processed, and the technology acuracy height is durable, and rising or falling speed is fast and lifting stable.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is the utility model structural representation.10, stationary work-table; 7, tooth bar; 2, locking silk; 11, movable table.

Fig. 2 is the A-A cutaway view of Fig. 1.1, handle; 2, locking silk; 3, gear shaft; 4, hold-down support; 5, spring; 6, gear; 7, tooth bar; 8, flat key; 9, back-up ring.

As can be seen from Figure 2, the utility model is made up of handle 1, gear shaft 3, spring 5, gear 6, flat key 8, back-up ring 9, tooth bar 7, locking silk 2 etc.On stationary work-table 10, be provided with the hold-down support 4 of a projection with movable table 11 joints, hold-down support 4 is structure as a whole with stationary work-table 10, hold-down support 4 is provided with a hole, gear shaft 3 passes hole on lathe bed one sidewall and the hole on the hold-down support 4, its outer end is provided with handle 1, handle 1 is connected with gear shaft 3 by screw, gear 6 is equipped with in gear shaft 3 the inners, be provided with a chase in cog 6 the outside of gear shaft 3, be provided with back-up ring 9 in the chase, can prevent that gear 6 from sliding along gear shaft 3, gear shaft 3 and gear 6 inside are provided with flat key 8, on the gear shaft 3 between hold-down support 4 and the gear 6, be arranged with spring 5, can prevent that gear shaft 3 from outwards sliding.With reference to Fig. 1, tooth bar 7 vertically is fixed on the wall of movable table 11 lower middle position, gear 6 and tooth bar 7 engagements, movable table 11 is connected with stationary work-table 10 by dovetail groove, be provided with wedge in the dovetail groove of a side, be provided with locking silk 2 in lathe bed one side, locking silk 2 passes the wall of lathe bed one side, its the inner withstands on the wedge, and movable table 11 can slide up and down along stationary work-table 10.When need adjusting movable table 11 height, turning handle 1, gear 6 moves along tooth bar 7, drives movable table 11 and moves, and when movable table 11 arrives when requiring the position, tightens locking silk 2, the compressing wedge, by wedge with movable table 11 fixed-site.

Claims
