Abstract
The utility model discloses a height adjustment mechanism of a power head of a table-type tapping machine. The height adjustment mechanism comprises a screw rod and a screw barrel, wherein the screw rod is movably positioned on a supporting tube of the tapping machine through a positioning sleeve, an adjustment handwheel is installed on the head of the screw rod, the lower portion of the screw rod stretches into the supporting tube to be in threaded connection with the screw barrel after penetrating through the positioning sleeve, and the screw barrel is fixedly connected with a cantilever of the tapping machine through a plurality of bolts after passing through a longitudinal adjustment hole installed in the supporting tube of the tapping machine. In conclusion, the height adjustment mechanism achieves rapid lifting and descending of the cantilever through a screw rod type mechanical transmission structure, and has the advantages of being simple and convenient, labor-saving and high in adjustment precision.
Description
Technical field
The utility model relates to a kind of bench tapping machine, particularly a kind of 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 ' and by the fixed position unit head 4 of cantilever ', at this, for the height that adapts to the central different workpieces of actual processing is processed needs; Base 1 ' workbench and unit head 4 ' between height need adjust in good time; And the adjustment of unit head 4 ' 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 through a plurality of screw 31 ' adapter sleeves be located at stay pipe 2 ' on; In the adjustment process of cantilever 3 ' up and down; Need unclamp screw 31 ', manually move up and down cantilever 3 ' afterwards again to the needs position, last tighten the screws 31 again ' realize cantilever 3 ' stay pipe 2 ' on the location; Whole adjustment process bothers and requires great effort the also very bad control of the precision of adjustment.
The utility model content
To the problems referred to above, the utility model has designed a kind of height adjustment mechanism of bench tapping machine unit head, and it is through a screw mandrel formula mechanical transmission structure, 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:
A kind of height adjustment mechanism of bench tapping machine unit head is characterized in that: whole guiding mechanism comprises screw mandrel and swivel nut, and said screw mandrel passes through a positioning sleeve activity orientation on the stay pipe of tapping machine; The head of screw mandrel is installed an adjustment handwheel, and the bottom of screw mandrel is passed to be deep in the stay pipe behind the positioning sleeve and is threaded with swivel nut; Said swivel nut is fixed together with the cantilever of tapping machine after being arranged on the vertical adjustment hole on the tapping machine stay pipe through some bolts.
Further, be provided with connection bearing between above-mentioned positioning sleeve and the screw mandrel.
When the height of needs adjustment unit head; Directly through rotating the adjustment handwheel; And then the screw mandrel that drive and handwheel are connected rotates; Then utilize screw mandrel to realize moving up and down of swivel nut with being threaded of swivel nut, realize the height adjusting of unit head thereby the cantilever that drive and swivel nut are fixed together moves up and down synchronously.Whole adjustment process only need be rotated handwheel; Very laborsaving convenient, because of receiving the screw connection structure of screw mandrel and swivel nut fully, moving up and down of cantilever limit simultaneously, move up and down very steady; Can be precisely controlled to the distance that moves up and down, can be actual adjustment great convenience is provided.
Description of drawings
The three-dimensional structural scheme of mechanism of Fig. 1, existing bench tapping machine;
The planar structure sketch map of Fig. 2, the utility model;
The structural representation in A-A cross section among Fig. 3, the utility model Fig. 2.
The specific embodiment
Shown in Fig. 2 and 3; A kind of height adjustment mechanism of bench tapping machine unit head; Whole guiding mechanism comprises screw mandrel 1 and swivel nut 2; Said screw mandrel 1 passes through a positioning sleeve 3 activity orientation on the stay pipe 51 of tapping machine, and between positioning sleeve 3 and screw mandrel 1, is provided with the flexibility that connection bearing 31 is used to guarantee screw mandrel 1 rotation.
The head of said screw mandrel 1 is installed an adjustment handwheel 11, and the bottom of screw mandrel 1 is passed to be deep in the stay pipe 51 behind the positioning sleeve 3 and is threaded with swivel nut 2.Said swivel nut 2 is fixed together with the cantilever 52 of tapping machine after being arranged on the vertical adjustment hole 511 on the tapping machine stay pipe 51 through some bolts 21.
When the height of needs adjustment unit head 53; Directly through rotating adjustment handwheel 11; And then the screw mandrel 1 that drive and handwheel 11 are connected rotates; Then utilize screw mandrel 1 to realize moving up and down of swivel nut 2 with being threaded of swivel nut 2, realize the height adjusting of unit head 53 thereby the cantilever 52 that drive and swivel nut 2 are fixed together moves up and down synchronously.
The whole adjustment process of the utility model mechanism only need be rotated handwheel 11; Very laborsaving convenient; Because of receiving the screw mandrel 1 and the screw connection structure of swivel nut 2 fully, moving up and down of cantilever 52 limit simultaneously; Move up and down very steady, can be precisely controlled to the distance that unit head 53 moves up and down, for reality adjustment provides 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.
Claims (2)
1. the height adjustment mechanism of a bench tapping machine unit head, it is characterized in that: whole guiding mechanism comprises screw mandrel and swivel nut, said screw mandrel through a positioning sleeve activity orientation on the stay pipe of tapping machine; The head of screw mandrel is installed an adjustment handwheel, and the bottom of screw mandrel is passed to be deep in the stay pipe behind the positioning sleeve and is threaded with swivel nut; Said swivel nut is fixed together with the cantilever of tapping machine after being arranged on the vertical adjustment hole on the tapping machine stay pipe through some bolts.
