Description

Drill jig tool for window screw hole of water level gauge body

Technical Field

The invention relates to a tool for processing a screw hole in a water level gauge body, in particular to a drill jig tool for a screw hole in a window of the water level gauge body.

Background

The water level gauge body is a main component of the water level gauge, the water level gauge body is provided with strip-shaped windows at intervals, window screw holes are formed in the water level gauge body located on the periphery of the strip-shaped windows, when the water level gauge body is subjected to strip-shaped visual inspection, a press cover is required to be pressed and sealed by the press cover, and at the moment, the press cover is fixedly pressed on the windows through bolts and the window screw holes in the water level gauge body in a matched mode.

The processing of window screw on the water level gauge body needs to be firstly marked one by a marking ruler to determine the drilling position, and then drilling is carried out by a drilling tool. Because the window that sets up on the fluviograph body is more, and a plurality of screw will be established to the periphery of every window, consequently the traditional use marking ruler marking off work load one by one is extremely huge, has greatly reduced the efficiency of fluviograph body screw processing.

Disclosure of Invention

The invention aims to solve the technical problem of providing a jig tool for a window screw hole of a water level gauge body, which can directly drill holes on a water level gauge body around a strip-shaped window without marking.

In order to solve the technical problem, the drill jig tool for the window screw hole of the water level gauge body comprises a rectangular drill jig template, an expansion sleeve and expansion nails matched with the expansion sleeve, wherein the drill jig template is provided with a long strip-shaped positioning groove, two sides of the long strip-shaped positioning groove are respectively provided with an expansion sleeve mounting hole, the drill jig template along the periphery of the long strip-shaped positioning groove is provided with a plurality of drilled holes, the expansion sleeves are respectively arranged in the expansion sleeve mounting holes on two sides of the long strip-shaped positioning groove, and each expansion sleeve is internally provided with the expansion nail.

As an improvement of the invention, each drill hole is internally provided with a drill sleeve in interference fit.

As a further improvement of the invention, the positioning block is arranged in the elongated positioning groove along the length direction, and the mounting holes of the expansion sleeve are respectively arranged at two sides of the positioning block.

The invention has the beneficial technical effects that: 1. by applying the invention, the pre-hole can be processed at the position corresponding to the window screw hole on the water level gauge body, and the window screw hole can be further directly processed by a drilling tool without using a scribing ruler to scribe one by one, thus greatly improving the processing efficiency of the window screw hole; 2. the drill bushing in interference fit is arranged in each drill hole, so that waste caused by replacement of the whole drill jig template due to abrasion of the drill holes can be avoided, and only the drill bushing needs to be replaced when the drill bushing is abraded; 3. adopt be equipped with in the rectangular shape constant head tank along length direction's locating piece, expand the technical characteristic back that the cover mounting hole branch was arranged in the both sides of locating piece, can inject the position of expanding the cover in the constant head tank.

Detailed Description

Referring to fig. 1 to 3, a water level gauge in the prior art mainly includes a water level gauge body 100, an air valve 101 and a water valve 102 are respectively connected to the upper portion and the lower portion of the water level gauge body, a plurality of elongated windows 103 are alternately arranged along the length direction of the water level gauge body, a gland 104 is press-fitted on the elongated windows, and a plurality of window screw holes 105 are formed in the water level gauge body around each elongated window.

Referring to fig. 4-11, the drill jig tool for the window screw hole of the water level gauge body comprises a rectangular drill jig template 1, an expansion sleeve 2 and an expansion nail 3 matched with the expansion sleeve, wherein the drill jig template is provided with a strip-shaped positioning groove 4, two sides of the strip-shaped positioning groove are respectively provided with an expansion sleeve mounting hole 5, a plurality of drill holes 6 are arranged on the drill jig template along the periphery of the strip-shaped positioning groove, each drill hole is internally provided with a drill sleeve 7 in interference fit, the expansion sleeve 2 is respectively arranged in the expansion sleeve mounting holes on two sides of the strip-shaped positioning groove, and the expansion nail 3 is arranged in each expansion sleeve 2. The strip-shaped positioning groove 4 is internally provided with a positioning block 8 along the length direction, and the expansion sleeve mounting holes 5 are respectively arranged on two sides of the positioning block 8.

In the invention, the outline size of the strip-shaped positioning groove 4 is slightly larger than the outline size of a strip-shaped window 103 on the water level gauge body, and the positions of a plurality of drill holes 6 arranged on the drill jig template correspond to the positions of a plurality of window screw holes 105 on the water level gauge body. When the invention is used, the drill jig template is arranged on the water level gauge body, the position of the strip-shaped positioning groove 4 on the drill jig template corresponds to the position of the strip-shaped window 103 on the water level gauge body, at the moment, the positions of the plurality of drill holes 6 also correspond to the positions of the plurality of window screw holes 105 one by one, the expansion sleeves 2 are arranged at two sides of the strip-shaped window 103, and the expansion nails 3 and the expansion sleeves 2 are rotated to be expanded in the strip-shaped window on the water level gauge body.
