Sheet metal equidistant perforating device based on ratchet motion principle

Abstract

The invention relates to the technical field of mechanical equipment, and discloses a sheet metal equidistant perforating device based on a ratchet motion principle. The sheet metal equidistant perforating device based on the ratchet motion principle comprises a rack, a workbench is fixedly connected to the inside of the rack, a fixing block is fixedly connected to the top of the workbench, and asliding block is slidably connected to the inside of the rack; a lifting rod is fixedly connected to the bottom of the sliding block, a perforating motor is fixedly connected to the bottom of the lifting rod, a drill bit is movably connected to the bottom of the perforating motor, a ratchet bar is fixedly connected to the top of the sliding block, and a limiting pawl block is movably connected tothe top of the ratchet bar; through cooperation of the ratchet bar, the limiting pawl block, an adjusting pawl block, a connecting rod, a limiting ring and a movable pin, an effect of driving the ratchet bar to slide rightwards equidistantly is achieved, it is guaranteed that the rightward moving distances of the drill bit are equal and hole distances among drilled holes are equal, the product quality is improved, therefore, the trouble that measurement and marking need to be carried out in advance is avoided, and the production efficiency of sheet metal perforating is effectively improved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a sheet metal isometric punching device based on the principle of ratchet movement. Background technique [0002] Sheet metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. It has been widely used in electronic appliances, communications, automobile industry, medical equipment and other fields. With the The application of sheet metal is becoming more and more extensive, and the design of sheet metal parts has become a very important part of the product development process. Mechanical engineers must master the design skills of sheet metal parts proficiently, so that the designed sheet metal can meet the functions and Appearance and other requirements can also make the stamping die manufacturing simple and low cost. [0003] Among them, in the ...

Problems solved by technology

[0003] Among them, in the process of sheet metal processing, it is often necessary to perform equidistant drilling on sheet metal. However, the existing equidistant drilling requires pre-punched punctuation, and then punches through the punctuation to ensure that the hole spacing is equal. However, this punching method is complicated to operate, low in work efficiency, and the punching accuracy of this punching method is low, and the distance error between the holes is larger, especially when the number of holes is large, the error between the hole distances is even greater. thereby affecting product quality
