Drilling automatic clamping device of double-lug supporting plate nut

Abstract

The invention relates to a drilling automatic clamping device of a double-lug supporting plate nut. A part positioning mechanism used for positioning the double-lug supporting plate nut is arranged below a double-servo power head, a waterproof metal plate used for guiding drilling cuttings into a drilling cuttings collecting box is arranged on the periphery of the upper part of an air cylinder pressing mechanism, the clamping and positioning mechanism is arranged on the upper part of the air cylinder pressing mechanism, and the cuttings collecting box is arranged on one side of the air cylinder pressing mechanism. According to the device, the double-servo drilling power head is adopted for realizing automatic drilling machining of parts, the positioning and clamping modes of the parts areimproved so that the product hole diameter size precision can be improved, the product machining consistency can be effectively improved, and the pneumatic clamping can effectively solve the problem of twining chips around a cutter during cutting; the drilling cuttings collecting box is arranged so as to prevent cutting fluid from splashing, so that the drilling machining environment is improved,meanwhile, the compatibility requirement of multi-model part drilling is met, and large-batch automatic production and machining of the double-lug supporting plate nut can be realized.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an automatic clamping device for drilling holes of double-ear bracket nuts. Background technique [0002] The bottom hole of the threaded nut of the support plate is processed by drilling. The equipment used in manual processing mainly includes a bench drill and a block. The function of the block is to roughly center the nut on the support plate and prevent the parts from rotating. The boss of the nut on the supporting plate is roughly positioned, but the precise positioning of the part cannot be guaranteed, and it is easy to cause the phenomenon of cutting and winding the drill bit, which cannot realize continuous processing. In addition, there is a phenomenon of cutting fluid splashing around during drilling. The size of the manually processed nuts can still meet the standard requirements, but the processed holes have uneven wall thickness and poor hole diameter c...
