Adjustable type longitudinal beam balance shaft set hole drilling template

Abstract

The invention provides an adjustable type longitudinal beam balance shaft set hole drilling template. The adjustable type longitudinal beam balance shaft set hole drilling template comprises an M15 screw and a countersunk head hexagon bolt; the diameter of a screw adjusting hole formed in an aerofoil drill positioning template is 18 mm, and five through holes are formed in the top end face of theaerofoil drill positioning template; a ventral side position is of a rectangular plate-shaped structure, and two positioning holes are formed in the front end of the interior of the ventral side position; the M15 screw is mounted on the aerofoil drill positioning template, and the top of the countersunk head hexagon bolt is mounted in the bottom of the aerofoil drill positioning template; the jackscrew height of the M15 screw on the aerofoil drill positioning template can be adjusted advantageously, thereby ensuring that the device is capable of better adapting the different height of a drilltemplate and an L plate, ensuring that when the drill template is clamped, the drill template and the L plate apply mutually acts and do not shake relatively, ensuring the set hole drilling quality, and avoiding occurrence of the hole position shafting problem completely.

Description

technical field [0001] The invention belongs to the technical field of optimizing and improving the drilling procedure of the grouping holes for the balance shaft of the longitudinal beam of a commercial vehicle, and more specifically relates to an adjustable drilling template for the grouping holes of the balance shaft of the longitudinal beam. Background technique [0002] The assembly of the balance shaft of commercial vehicles adopts the group hole method. After the longitudinal beam is formed, the inner beam and L plate are inlaid inside the U-shape of the longitudinal beam; considering the angle of the longitudinal beam and the error of the inlay process, people will use professional drilling templates to deal with the error question. [0003] Based on the above, the inventors have found that the existing common drilling formwork is difficult to maintain the same height difference between the L plate and the airfoil of the stringer during use; Inconsistent heights lea...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an adjustable longitudinal beam balance shaft group hole drilling template to solve the existing common drilling template, which easily causes the height difference between the L plate and the longitudinal beam wing surface to be difficult to keep consistent during use; In the process, the ventral surface is used for positioning and the airfoil is drilled. Due to the inconsistent height of the longitudinal beam and the airfoil, the gap between the drilling template and the L plate is uncontrollable. Due to the existence of the gap during drilling, the drilling template shakes, and the hole deviation is easy to occur; and Can't adapt well to the problem of the error caused by the assembly of the stringer
