Abstract

The utility model discloses a universal tool for connection and fixation, which is provided with four through long-strip-shaped step holes distributed in a cross shape along a central line, can be used for connecting and fixing dies or parts with different shapes and sizes, does not need to be independently matched with and fixed with the dies or parts, has strong universality, effectively reduces purchasing and manufacturing cost, can be fixedly connected without passing through the dies or parts, reduces the height of the dies or parts, and reduces material cost and processing cost.

Description

Universal tool for connection and fixation

Technical Field

The utility model relates to a tool, in particular to a universal tool for connection and fixation.

Background

The existing fixture structure for mounting, connecting and fixing is poor in universality, one fixed fixture can only be connected with a single die or part with the matched size, and meanwhile, the same lamination is matched with the fixed fixture, so that the die or part is prevented from falling off; the length of the die or the part matched with the die or the part is higher than that of the fixing tool, and the tool can be fixed only by penetrating through the connecting and fixing tool. The matched tooling and the thickened die parts greatly increase the material and processing cost.

Disclosure of Invention

The utility model aims to: the utility model provides a universal tool for connection and fixation, which is high in universality and convenient to install.

The technical scheme is as follows: according to the universal fixture for connection and fixation, four through long-strip-shaped step holes which are distributed in a cross shape are arranged along the central line.

Preferably, the number of the step structures of the strip-shaped step holes is two or more.

Preferably, the ratio of the elongated step hole to the side length of the tool is 1:3-4.

Preferably, four long-strip-shaped step holes are further formed along the diagonal of the tool, so that the arrangement in the shape of a Chinese character 'mi'.

Preferably, the four elongated step holes arranged along the diagonal of the tool take the center of the tool as a fixed point, and are arranged in parallel or perpendicular to the central line.

Preferably, the bolts pass through the strip-shaped step holes on the general tool and are fixedly connected with the parts.

The beneficial effects are that: compared with the prior art, the utility model has the following advantages: (1) The die or parts with different shapes and sizes can be connected and fixed, the parts for fixing the die or the parts do not need to be matched independently, the universality is strong, and the purchasing and manufacturing cost is effectively reduced; (2) The fixed connection can be carried out without passing through a die or a part, the height of the die or the part is reduced, and the material cost and the processing cost are reduced.
