Abstract

The utility model discloses a height adjusting mechanism of power head of bench tapping machine. The mechanism comprises a worm gear pair and a spur rack. The worm gear pair is disposed in a mounting hole at the caudal part of the cantilever of the tapping machine, the worm gear pair contains a worm and a worm wheel, the outer end of the worm extends out of the mounting hole and is connected with a rocking arm, the inner end of the worm is provided with a worm gear structure engaged with the worm wheel, the inner side of the worm wheel is engaged with the spur rack, and the spur rack is longitudinally fixedly disposed on the side of a supporting tube of the tapping machine. The utility model realizes the rapid up and down of the cantilever by the worm gear pair transmission structure, is simple and labor saving, and has high adjustment accuracy.

Description

The height adjustment mechanism of bench tapping machine unit head
Technical field
The utility model relates to a kind of bench tapping machine, particularly the height adjustment mechanism of bench tapping machine unit head.
Background technology
Existing bench tapping machine structure is as shown in Figure 1; It comprises base 1 ', stay pipe 2 ', cantilever 3 ' with by the fixed position unit head (not shown) of cantilever, at this, for the height that adapts to the central different workpieces of actual processing is processed needs; Height between base 1 ' workbench and the unit head need be adjusted in good time; And the adjustment of unit head height be through the stay pipe 2 of cantilever 3 ' relatively ' height regulate and realize, but with regard to present structure, cantilever 3 ' afterbody be directly be set in stay pipe 2 ' on; Its utilize one be arranged on stay pipe 2 ' outside fixed cover 21 ' on bolt 22 ' hold bring in the location at cantilever 3 ' afterbody following; In the adjustment process of cantilever 3 ' up and down, through bolt 22 ' move up and down realize cantilever 3 ' stay pipe 2 ' on height adjustment, because of cantilever 3 ' add that the component of unit head is very heavy; Only lean on bolt 22 ' the adjustment meeting that turns require great effort very much the also very bad control of precision of adjustment simultaneously.
The utility model content
To the problems referred to above, the utility model has designed the height adjustment mechanism of bench tapping machine unit head, its drive mechanism through a worm gear, realize cantilever fast on lift and move down, have easy, laborsaving and the high characteristics of adjustment precision.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The height adjustment mechanism of bench tapping machine unit head is characterized in that: whole guiding mechanism comprises a worm gear and a spur rack; Said worm gear is arranged in the installing hole of tapping machine cantilever afterbody, and worm gear comprises worm and worm wheel, and the outer end of worm screw is stretched out installing hole and connected a rocking arm, and the inner of worm screw is provided with wrom tooth structure and worm gear engagement; The inboard of said worm gear and the engagement of said spur rack, spur rack vertically is fixedly installed on the side of tapping machine stay pipe.
Further, the outstanding stay pipe sidewall setting of above-mentioned spur rack and be connected with draw-in groove in the tapping machine cantilever afterbody endoporus.
When the height of needs adjustment unit head; Rotate rocking arm and drive the worm screw rotation; Utilize the engaged transmission of inner wrom tooth of worm screw and worm gear to drive the worm gear rotation, then the engaged transmission through worm gear and spur rack moves up and down the relative spur rack of cantilever, realizes that the height of the relative base of unit head is regulated.
Above adjustment process only need be rotated rocking arm; Whole adjustment process is very laborsaving convenient; Simultaneously receive worm gear and the spur rack structural limitations that is connected with a joggle fully because of moving up and down of cantilever; Moving up and down of cantilever is very steady, can accurately control the distance that unit head moves up and down, for the unit head height adjustment in the reality use provides great convenience.
Description of drawings
The three-dimensional structural scheme of mechanism of Fig. 1, existing bench tapping machine;
The perspective view of Fig. 2, the utility model;
The cross section structure sketch map of Fig. 3, the utility model figure.
The specific embodiment
Shown in Fig. 2 and 3, the height adjustment mechanism of bench tapping machine unit head, whole guiding mechanism comprises a worm gear 1 and a spur rack 2.
Said worm gear 1 is arranged in the installing hole 311 of tapping machine cantilever 31 afterbodys, and worm gear 1 comprises worm screw 11 and worm gear 12, and the outer end of worm screw 1 is stretched out installing hole 311 and connected a rocking arm 111, and the inner of worm screw 11 is provided with wrom tooth 112 structures and worm gear 12 engagements.The inboard of said worm gear 12 and 2 engagements of said spur rack, spur rack 2 vertically is fixedly installed on the side of tapping machine stay pipe 32.
At this; The outstanding stay pipe 32 sidewall settings of the spur rack 2 of the utility model also cooperate and form and engage syndeton with draw-in groove 312 in the tapping machine cantilever 31 afterbody endoporus; This structure is provided with, and can stopping in the adjustment process that cantilever 31 moves up and down relatively, stay pipe 32 rotates.
When the height of needs adjustment unit head 33; Rotate rocking arm 111 and drive worm screw 11 rotations; Utilize the worm screw 11 inner wrom tooths 112 and the engaged transmission of worm gear 12 to drive worm gear 12 rotations; Then the engaged transmission through worm gear 12 and spur rack 2 moves up and down cantilever 31 relative spur racks 2, realizes that the height of unit head 33 relative bases 34 is regulated.
Above adjustment process only need be rotated rocking arm 111; Whole adjustment process is very laborsaving convenient; Simultaneously receive worm gear 1 and spur rack 2 structural limitations that is connected with a joggle fully because of moving up and down of cantilever 31; Moving up and down of cantilever 31 is very steady, can accurately control the distance that unit head 33 moves up and down, for unit head 33 height adjustment in the reality use provide great convenience.
The above; It only is the preferred embodiments of the utility model; Be not that the utility model is done any pro forma restriction; Every know-why according to the utility model still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations or modification that above embodiment did.
