Embodiment 1

[0019] Such as figure 1 and figure 2 As shown, the positioning device includes a positioning piece 3 fixed on the bracket 1 , a positioning piece 2 located directly below the positioning piece 3 , and a positioning piece 3 4 located outside the positioning piece 3 . The second positioning part is connected to the bracket 1 through the slide rail; the third positioning part 4 is fixedly connected to the bracket 1 through the support rod 2 . The thin-walled drill base body 5 is vertically arranged with its head facing up and can be positioned by a positioning piece 3, a positioning piece two, and a positioning piece three 4.

[0020] The indexing device includes a base 7 and an indexing rod 8 . Specifically, the indexing rod 8 is rod-shaped and one end is hinged on the base 7, the other end of the indexing rod 8 is a free end and the end can be positioned with one of the thin-walled drill bit 6 positioned on the support 1 end faces against each other.

[0021] The support r...

Embodiment 2

[0030] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that the base 7 is connected to the support rod 2 through the index plate 10 in order to facilitate the rotation of the base 7 and improve the accuracy of the rotation angle. The bottom of the base 7 is fixed at the center of the index plate 10, and the index plate 10 is fixed on the support rod 2 by bolts and nuts. The index plate 10 is a kind of mechanism that can make the base 7 rotate, index and locate. The structure of the index plate 10 is mainly composed of a clamping part, an indexing and positioning part, and a transmission part.

Abstract

The invention provides an indexing device of a welding stand of a thin-wall drill, belonging to the technical field of machinery. The indexing device solves the problems that the efficiency is low, and the precision can not be ensured in the conventional method of manually and equally indexing a crossed line of a thin-wall drill basal body. The indexing device of the welding stand of the thin-wall drill is arranged on the stand and comprises a base and an indexing lever, wherein the base is fixedly connected to the stand, and the indexing lever is in a shape of a lever; and one end of the indexing lever is hinged on the base, and the other end of the indexing lever is a free end and can support against the end surface of a tool bit of the thin-wall drill located on the stand. The indexing device of the welding stand of the thin-wall drill has the advantages of simple structure, convenient use, rotating degree restriction of the thin-wall drill basal body and small degree error guarantee of rotating degree at every turn, thereby effectively ensuring the even distribution of tool bits fixed on the basal body and improving the quality of the thin-wall drill.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a thin-wall drill welding frame, in particular to an indexing device for a thin-wall drill welding frame. Background technique [0002] With the development of science and technology and the improvement of industrial production level, cutting saw blades and engineering drill bits with synthetic diamond heads as cutting edges have been widely used. There are more and more occasions where thin-walled engineering drills are used in construction, transportation, metal processing and other industries, especially in the construction and decoration industry. Because thin-walled diamond engineering drills have the advantages of accurate drilling size, fast speed, and no damage to surrounding materials And the characteristics of no need for follow-up procedures make it the best choice for drilling small holes and large-diameter holes in various building materials. At present, diamond thi...
