Drilling device for auto parts

Abstract

The invention relates to the technical field of automobile part processing and discloses a perforating device for automobile parts. The perforating device for automobile parts comprises a rack, wherein a worktable is slidably connected to the rack and an air supply box is fixedly connected to the rack; a first air chamber and a second air chamber communicate to the air supply box; a first worm wheel is rotatably connected to the first air chamber; a first gear is coaxially connected to the first worm wheel; a first rack is engaged to the first gear; a second worm wheel is rotatably connected in the second air chamber; a second gear is coaxially connected to the second worm wheel; a second rack is engaged to the second gear; a perforating pile is rotatably connected to the second rack; a spline sleeve sleeves the perforating pile; a third air chamber communicating to the first and second air chambers is fixedly connected to the rack; a third worm wheel is connected to the spline sleevein a sleeving manner; an adjusting mechanism is arranged on the worktable; a first touch switch for closing the air supply box is mounted on the adjusting mechanism; and a supporting rod leaning against the first touch switch is arranged on the third air chamber. The perforating device for automobile parts provided by the invention can adjust the perforating depth and improves the perforating efficiency.

Description

Technical field [0001] The invention relates to the technical field of automobile parts processing, in particular to a punching device for automobile parts. Background technique [0002] During the processing of auto parts, in order to facilitate the installation of auto parts, the auto parts are usually punched. Traditional drilling methods use manual hand-held drilling machines for drilling. During the drilling process, the force cannot be kept the same each time, which easily leads to inconsistent depths of the holes on the auto parts after the same batch of drilling, resulting in automobile zero The parts have different specifications, which reduces the qualified rate of processing, and manual drilling is labor-intensive and low in efficiency, which is not suitable for mass production. [0003] In order to solve the above-mentioned problems, the Chinese patent (CN104174758B) discloses a hole pressing machine for auto parts. The hole pressing machine includes a trapezoidal supp...

Problems solved by technology

[0004] Although the above-mentioned patent solution solves the deficiencies in the traditional punching method to a certain extent, there are still some points to be improved in this solution: when the punching machine is punched, the worker needs to hold the handle to operate. On the one hand, punching The efficiency of the hole is still not high. On the other hand, although there is a resistance block to prevent the hole from being punched through too much force, it still cannot guarantee that the worker applies the same force every time, so it is easy As a result, the depth of the holes after processing the same batch of auto parts is quite different, resulting in a decline in the pass rate
