Embodiment Construction

[0027] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] This embodiment proposes a positioning and fixing tool for a hand electric drill, the structure of which is as follows: figure 1 As shown, it mainly includes a split center frame 2, an adjustable backing plate 4, a fixing block 10, a profiling pressing block 7, a U-shaped screw 8 and an anti-off fixing seat 9.

[0029] like figure 2 As shown, the two ends of the insulated hand drill 3 are respectively provided with a center positioning journal 3-1 and a card slot 3-2. Wherein, the central positioning journal 3 - 1 is used for the positioning shaft of the split center frame 2 , and the slot 3 - 2 is used for positioning of the anti-loosening fixing seat 9 . The centering journal 3-1 is smaller than the drill ch...

Abstract

The invention provides a drilling positioning fixing tool for an electric hand drill. The tool mainly comprises a split center frame, an adjustable base plate, a profiling pressing block, a U-shaped screw rod and an anti-falling fixing seat. According to the tool, the split center frame is adopted so that a journal can be conveniently positioned and mounted; the adjustable base plate and an adjustable supporting screw are adopted so that the height of an electric hand drill body can be adjusted; a guiding groove is formed in the adjustable base plate so that positioning guiding can be conducted by means of a guiding screw; the profiling pressing block and a U-shaped bolt are adopted for fastening, and a tail conducts jacking and anti-loosing through a fixing block and a jacking bolt so that the electric hand drill can be fastened; the anti-falling fixing seat is adopted, and a clamping groove of the electric hand drill is used for positioning so that the electric hand drill can be prevented from moving backwards due to drilling counter-acting force; and in combination with the use of a drill jig, the electric hand drill rotates around a rotating center shaft of a rotating fixing seat so that the center distance can be kept unchanged during drilling.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a drilling positioning and fixing tool for a hand electric drill. Background technique [0002] The traditional metal shell electric drill originally used in the drilling operation has a regular shape, and the hand electric drill drilling tool can be made by drilling holes in appropriate parts of the metal shell and fixing the electric drill with screws. The size of the journal of this kind of hand electric drill is usually larger than that of the drill chuck, and it can be positioned directly by welding and fixing the collar to locate the journal, and the structure is relatively simple. However, the metal casing electric drill is not insulated, does not meet the safety performance requirements, and is gradually eliminated. Nowadays, electric hand drills with plastic shells are commonly used, which have complex shapes, and the journal size is usually sm...
