Description

[Technical Field]

[0001] This invention relates to the technical field of nut processing, and in particular to the technical field of nut drilling equipment. [Background Technology]

[0002] A nut is a fastener that is screwed onto a bolt or threaded rod to secure a fastener. It is an essential component in all manufacturing machinery. Depending on the material, nuts are classified into several types, such as carbon steel, stainless steel, and non-ferrous metals.

[0003] To enhance the locking effect, irregularly shaped nuts often have through holes drilled from the outer surface to the inner threaded surface, and locking components are installed within these holes. Patent document CN 214236393U discloses an adjustable nut drilling device capable of drilling holes for different nut sizes. However, this device can only drill at a single location on the nut, failing to meet the needs of multi-station drilling, resulting in low production efficiency. Furthermore, the device cannot handle the drilling debris, which spreads into the working environment, adversely affecting operators. [Summary of the Invention]

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a nut drilling device that can drill holes in multiple locations of the nut, while preventing debris from splashing into the external environment and keeping the working environment clean.

[0005] To achieve the above objectives, this invention proposes a nut drilling device, including a processing table with a vertical groove on its upper surface. A mounting seat is slidably installed inside the groove, and the mounting seat can move up and down within the groove. A nut body is placed on the mounting seat. The processing table has a drilling station, an adjustment station, and a material unloading station arranged sequentially from top to bottom. A support is mounted on the upper surface of the processing table, and a lifting cylinder is mounted on the support. The output end of the lifting cylinder is equipped with a clamping cap. A discharge channel is provided on the mounting seat, and a waste pipe is connected to the bottom of the discharge channel. The pipe is connected to a waste collection box. Two drilling mechanisms are symmetrically arranged on the left and right sides of the drilling station. Two fixing mechanisms are symmetrically arranged on the front and rear sides of the drilling station. The drilling mechanism includes a drilling cylinder, a drilling motor, and a drill bit. The processing table has a mounting slot for accommodating the drilling mechanism. The drilling motor is installed at the output end of the drilling cylinder, and the drill bit is installed at the output end of the drilling motor. The fixing mechanism includes a clamping cylinder and a fixing block. The fixing block is fixed at the output end of the clamping cylinder, and a limiting groove matching the nut is provided on the fixing block.

[0006] Preferably, the clamping cover is provided with cooling pipes on the left and right sides, and coolant is provided in the cooling pipes. The outlet end of the cooling pipe is located above the drill bit. The top of the clamping cover is provided with a fan that blows air towards the discharge channel.

[0007] Preferably, an annular turntable is rotatably mounted on the outer periphery of the adjustment station. A gear is provided on the outer side of the annular turntable, and the gear meshes with a rotating gear. The rotating gear is connected to an adjustment motor. Two adjustment mechanisms are symmetrically arranged on both sides of the annular turntable. A receiving groove for accommodating the adjustment mechanisms is provided on the processing table. The adjustment mechanism includes an adjustment cylinder and a clamping block. The clamping block is located at the output end of the adjustment cylinder. An annular sealing ring is provided on the end face of the clamping block near the nut. An air blowing channel is provided inside the clamping block. The air outlet of the air blowing channel is located inside the annular sealing ring. An air supply pipe is connected to the air inlet of the air blowing channel. The air supply pipe is connected to an air pump.

[0008] Preferably, linear motor tracks are installed on the left and right sides of the slide groove, and a movable plate is slidably installed on the linear motor tracks. The mounting base is fixedly connected to the movable plate. Two linear motor slide rails are provided on each side, and the two linear motor slide rails are installed one in front of the other on the side of the mounting base.

[0009] Preferably, a turntable is rotatably mounted on the top of the mounting base, and an electromagnet is embedded in the turntable.

[0010] Preferably, the side of the turntable is a tapered surface, and a scraper is connected to the side of the turntable, with the lower surface of the scraper in contact with the upper surface of the mounting base.

[0011] Preferably, the processing table is connected to a feeding platform, and a feeding mechanism is installed on the feeding platform. The feeding mechanism includes a feeding cylinder and a feeding block. The feeding cylinder is located behind the mounting base, and a feeding block is installed at the output end of the feeding cylinder.

[0012] Preferably, a feeding cylinder is provided on the left side of the feeding station, and a push plate is provided at the output end of the feeding cylinder. A discharge channel is provided on the right side of the feeding station. The discharge channel is inclined and a collection box is provided at the outlet of the discharge channel.

[0013] The beneficial effects of this invention are as follows: By setting the drilling station inside the chute, this invention avoids exposure to the external environment and reduces the splashing of waste chips; during drilling, the nut is clamped by the fixing mechanisms on both sides and pressed by the pressure cover to prevent the nut from moving during processing and ensure processing quality; after drilling is completed, the nut is moved down to the adjustment station for adjustment. The clamping block of the adjustment station clamps the nut, and then the nut is rotated by the turntable to rotate the other side of the nut that needs to be processed to the direction of the drilling mechanism. This allows for automatic drilling of multiple positions of multiple nuts, resulting in high processing efficiency; while the clamping block is clamping, the drilled through hole is cleaned by blowing air through the air channel, reducing waste chip residue.
