Equidistant hole pressing device for automobile parts based on special-shaped gear transmission principle

Abstract

The invention relates to the automobile part technology field and discloses an equidistant hole pressing device for automobile parts based on a special-shaped gear transmission principle. The device comprises a frame body. The frame body is fixedly connected with a supporting plate. A material leaking hole is arranged in the supporting plate. A top of the supporting plate is slidably connected with a plate. The top of the plate is slidably connected with a material guide wheel. A material guide shaft is fixedly connected to an inner portion of the material guide wheel. A pawl is hinged to an outer portion of the material guide shaft. An outer portion of the pawl is fixedly connected with a spring. The outer portion of the material guide shaft is movably connected with a ratchet wheel gearring. The outer portion of the ratchet wheel gear ring is in engaged connection with a double-sided gear rod. Through cooperative use of a pressing rod and a second telescopic rod, stability of a pressure block is guaranteed, and the stability of a drill bit in a drilling process is ensured so that the drill bit is accurate in positioning, drilling precision is improved, and a situation that the drill bit deviates so that a structure near an accessory hole is damaged is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an equidistant punching device for auto parts based on the transmission principle of special-shaped gears. Background technique [0002] Auto parts are the various units that make up the whole car and a product that serves the car. There are many kinds of auto parts. With the improvement of people's living standards, people consume more and more cars, and the market for auto parts is also growing. In recent years, auto parts manufacturers are also developing rapidly. There are many guards or plates, and these plates often need to be perforated to achieve their functions. [0003] The existing drilling method is to use a puncher to punch holes after determining the position of the hole. When the puncher is punching holes, the drill bit is often prone to offset, resulting in hole offset and damage to the auto parts hole. The nearby structure, and when the hole punch is in use,...

[0003] The existing drilling method is to use a puncher to punch holes after determining the position of the hole. When the puncher is punching holes, the drill bit is often prone to offset, resulting in hole offset and damage to the auto parts hole. The nearby structure, and when the hole punch is in use, the depth of the hole cannot be controlled. If the force is small, the depth of the hole cannot meet the requirements. At this time, the spacing of the holes cannot be accurately guaranteed, and it often takes multiple measurements and punctuation to determine the spacing of the holes. There will be large errors, and even lead to the scrapping of parts, resulting in waste of materials; in addition, during the drilling process, there is often no corresponding discharge device, so that waste materials accumulate on the surface of the parts, which easily leads to scratches on the surface of the parts and affects the surface finish of the parts and beautiful parts
