Abstract
The adjustable auxiliary support structure that the utility model relates to a kind of on Horizontal type manual chasing bar is made of lower part adjusting screw rod, adjusting nut and upper support pipe sleeve；In lower part, the lower end of adjusting screw rod is welded with bottom plate, and bottom plate is fixed on the workbench of chasing bar；It is welded with curved support panel in the upper end of upper support casing, curved support panel forms support with the lower part of shaft and contacts；The upper end of the lower part adjusting screw rod forms to install and connect with the lower end of upper support pipe sleeve, and the adjusting nut is tightened on the adjusting screw rod of lower part, and the upper surface of adjusting nut and the lower end of upper support pipe sleeve are pressed into contact with.This is adjustable, and auxiliary support structure has the advantages that easy to adjust, strong applicability.
Description
Technical field
The utility model belongs to technical field of mechanical processing, is related to Tapping Technology, more particularly to a kind of for Horizontal type manual
Adjustable auxiliary support structure on chasing bar.
Background technique
Currently, process screw thread on workpiece has by the way of: being processed on tapping machine, with homemade hand tapping
Device is processed, and is processed etc. with hand tapping tool.Wherein, the Manual tapping device of simple self-made is because of equipment cost
Low, the advantages that processing is laborsaving, tapped bore less, screw thread process amount be not that very big manufacturing enterprise has obtained universal answer
With.
Horizontal type manual chasing bar is a kind of common self-control Manual tapping device, this kind of chasing bar is mainly by L-type base
Seat is mounted on tapping bar on pedestal stile, is installed on the handle of tapping bar outer end and is installed on the drill chuck structure of tapping bar inner end
At.Wherein, the lower horizontal edge of L-type pedestal is used as the workbench for placing workpiece, can be in work according to the design feature of processing part
Make to fix corresponding workpiece positioning tool on platform.
For existing self-control Manual tapping machine due to fixing tapping position, tapping shaft cannot adjust position up and down, cause to attack
The scope of application of silk machine is limited.
For the shortcoming of existing Manual tapping machine, what a kind of pre-designed tapping shaft can be adjusted and be fixed up and down
Novel manual tapping machine, since tapping shaft can adjust position up and down, then the auxiliary support structure of existing firm tapping shaft by
It fixes, therefore is not suitable on novel manual tapping machine in Support Position.
It retrieves, does not retrieve and technical solution similar in this patent through the prior art.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, provide a kind of easy to adjust, strong applicability
For the adjustable auxiliary support structure on Horizontal type manual chasing bar.
The utility model solves its technical problem and adopts the following technical solutions to achieve:
A kind of adjustable auxiliary support structure on Horizontal type manual chasing bar, it is characterised in that: spiral shell is adjusted by lower part
Bar, adjusting nut and upper support pipe sleeve are constituted；In lower part, the lower end of adjusting screw rod is welded with bottom plate, and bottom plate is fixed on tapping dress
On the workbench set；Curved support panel, curved support panel and tapping shaft are welded in the upper end of upper support casing
Support contact is formed at lower part；The upper end of the lower part adjusting screw rod forms to install and connect with the lower end of upper support pipe sleeve,
The adjusting nut is tightened on the adjusting screw rod of lower part, and the upper surface of adjusting nut compresses with the lower end of upper support pipe sleeve and connects
Touching.
And, the curved support panel is constituted by upper and lower two layers, and upper layer is made of wear-resistant material, upper layer and tapping
The lower part of shaft directly contacts, and lower layer is made of ordinary carbon steel material.
The advantages and positive effects of the utility model are as follows:
1, this adjustable auxiliary support structure can make upper support pipe sleeve along the adjusting screw rod of lower part by adjusting adjusting nut
It moves or moves down, to realize the matching adjusted with tapping shaft upper and lower position, guarantee that the curved support panel of upper support casing begins
It is supported in the lower part of tapping shaft eventually.Originally adjustable auxiliary support structure improves the stability of tapping shaft work, thus favorably
In the accuracy for guaranteeing tapping position.
2, this adjustable auxiliary support structure has the advantages that easy to adjust, not by Horizontal type manual chasing bar main part knot
The limitation of structure, it may have the advantages of strong applicability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the use state of the utility model with reference to figure.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of adjustable auxiliary support structure on Horizontal type manual chasing bar, by lower part adjusting screw rod 6, adjusting nut
5 and upper support pipe sleeve 4 constitute, rectangular pipe sleeve, round pipe sleeve etc. can be used in upper support pipe sleeve.Under the adjusting screw rod of lower part
End is welded with bottom plate 7, and square plate structure can be used in bottom plate, and bottom plate is fixed by bolts on the workbench 8 of chasing bar.?
The upper end of upper support casing is welded with curved support panel, and the lower part formation support of curved support panel and tapping shaft 1 connects
Touching.The upper end of the lower part adjusting screw rod forms to install and connect with the lower end of upper support pipe sleeve, the adjusting nut rotation
Tightly on the adjusting screw rod of lower part, the upper surface of adjusting nut and the lower end of upper support pipe sleeve are pressed into contact with.
The curved support panel is preferably constituted by upper and lower two layers, and upper layer 2 is made of wear-resistant material, such as ceramic material,
Upper layer is directly contacted with the lower part of tapping shaft, and lower layer 3 is made of ordinary carbon steel material.Separable assembled knot can be used in upper and lower layer
Structure can also coat wear-resistant material in lower layer upper surface and form upper layer.
Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with
Understand: departing from the utility model and spirit and scope of the appended claims, various substitutions, changes and modifications are all can
Can, therefore, the scope of the utility model is not limited to the embodiment and attached drawing disclosure of that.
