Problems solved by technology

[0002] Special vehicles usually need to install support feet, lower hanging boxes and other lower hanging parts in the middle of the chassis frame. Due to the narrow assembly space, it is generally necessary to drill the chassis frame of the vehicle to process the bottom hole, and then directly use the bolt group to install the lower hanging parts. It is fastened to the chassis girder, but because the thickness of one side of the chassis girder is generally 10mm~12mm, and the drilling stage is usually carried out by workers with hand-held electric drills, it is prone to shaking, which will cause the hole body to be skewed, the hole is not round, and even become a hole. Triangular holes or special-shaped holes lead to poor bottom hole quality. This irregular bottom hole will make the thread incomplete during tapping, which makes the lower pendant easy to produce slippage during installation and connection, or in the driving process after installation. The case where the medium thread is easy to loosen

Abstract

The invention discloses an auxiliary fixture for drilling for an automobile chassis beam, and relates to the technical field of vehicle manufacturing. The auxiliary fixture for drilling for the automobile chassis beam comprises a clamping element hooked onto the chassis beam and a brace rod used for being abutted against the clamping element and pressing an electric drill, wherein the clamping element comprises a main rod; a hook rod is connected to the front end of the main rod; a vertical rod is vertically connected to the rear end of the main rod; a first reinforcing rod is connected between the main rod and the vertical rod; and a triangular hole allowing the brace rod to penetrate through is encircled by the main rod, the vertical rod and the first reinforcing rod. According to the auxiliary fixture for drilling for the automobile chassis beam, the quality of drilling a bottom hole in the chassis beam can be improved, the incompletion of a thread during the subsequent tapping is avoided, and the firmness of the subsequent installation for a lower hanging element is enhanced.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to an auxiliary tooling for drilling a frame beam of an automobile chassis. Background technique [0002] Special vehicles usually need to install support feet, lower hanging boxes and other lower hanging parts in the middle of the chassis frame. Due to the narrow assembly space, it is generally necessary to drill the chassis frame of the vehicle to process the bottom hole, and then directly use the bolt group to install the lower hanging parts. It is fastened to the chassis girder, but because the thickness of one side of the chassis girder is generally 10mm~12mm, and the drilling stage is usually carried out by workers with hand-held electric drills, it is prone to shaking, which will cause the hole body to be skewed, the hole is not round, and even become a hole. Triangular holes or special-shaped holes lead to poor bottom hole quality. This irregular bottom hole wi...
