Description

Technical Field

[0001] This invention relates to the field of aerospace fastener processing equipment technology, specifically a defect removal device based on threaded fasteners. Background Technology

[0002] Threaded fasteners are mechanical parts used to connect two or more components. They typically consist of a cylindrical object and one or more threaded rings. These parts are commonly used to secure bolts, nuts, screws, etc., to achieve the fixing and connection of mechanical equipment. Threaded fasteners are widely used in various mechanical equipment, such as automotive, construction, aerospace, and electronic equipment. They can withstand high-strength and heavy loads and can be easily disassembled and reassembled. During the manufacturing process, threaded fasteners typically undergo heat treatment, machining, and surface treatment processes to ensure that their strength, wear resistance, and corrosion resistance meet requirements. Simultaneously, to ensure the accuracy and stability of threaded fasteners, rigorous testing and quality control are also necessary.

[0003] During the machining of general threaded fasteners, cutting and cold rolling processes can create irregular sharp corners and half-tooth defects in the thread profile. If these defects are not removed, when the threaded fastener is screwed in and out during use, the sharp corners will cause burrs and iron filings, resulting in rotten teeth and affecting the use of the threaded fastener. Threaded fasteners will also develop surface defects during use, requiring the use of a threaded fastener defect removal device to treat these defects.

[0004] For example, Chinese patent application CN101704207B discloses a device for removing defects at the beginning and end of threaded fasteners. This device consists of a guide wheel handle, a guide wheel, a pneumatic grinding wheel, and a feeding mechanism. The guide wheel handle is fixedly connected to one side of the outer circumference of the guide wheel, and the other side is fixedly connected to the feeding mechanism. The pneumatic grinding wheel is connected to the corresponding position of the feeding mechanism. In use, the feeding mechanism controls the radial feed of the pneumatic grinding wheel, and compressed air drives the pneumatic grinding wheel to rotate axially, thus removing thread defects at the beginning and end of the fastener. However, when this device treats thread profile defects such as sharp corners and half-threads on threaded fasteners, it uses a grinding wheel to grind the defective area. During grinding, a clamp is needed to fix the threaded fastener. When fixing the threaded fastener, the clamp is usually used to hold both sides of the threaded fastener's end. This makes the installation and positioning of the threaded fastener cumbersome and inconvenient. Summary of the Invention

[0024] The present invention has at least the following beneficial effects:

[0025] (1) When the bolt reaches the outlet, the rod-shaped part of the bolt is facing down and falls into the guide tube. The top of the guide tube is equipped with a guide to facilitate the bolt falling vertically into the guide tube. The inner wall of the guide tube can only allow the bolt to fall vertically. The top of the clamp mounting frame is connected to the guide tube. The bolt falls into the clamp mounting frame and onto the fixed clamp. When the two fixed clamps are closed, the top of the bolt is fixed. The bolt rod is exposed at the bottom of the clamp mounting frame.

[0026] (2) In this solution, the fan is started when the bolts are being ground, and the air is drawn out through the fan connection pipe.

The first strainer is set to block the bolts that have fallen after grinding, and the second strainer is set to block the debris. The collection bag is installed at the bottom of the absorption frame with screws, which is easy to disassemble.

[0027] (3) The water pump starts to pump water, and clean water is sprayed out from the nozzle to clean the bolts below. At the same time, the hydraulic cylinder starts and the output end reciprocates, driving the baffle plate to rotate back and forth on one side of the inner wall of the cleaning water tank, turning the bolts to rinse them. After rinsing, the water spraying stops, the heat pump starts, and hot air is blown down through the warm air supply pipe to dry the bolts, making bolt cleaning more convenient.

[0028] (4) The electrophoresis pool in this scheme contains a mixture of paint, latex, rubber and other particles. After the electrophoresis pool is powered on, the paint, latex, rubber and other particles are evenly covered on the surface of the bolts to treat the defects on the bolt surface. At the same time as the electrophoresis treatment, the vibrating motor drives the inclined plate to vibrate, which can drive the bolts to move to one side of the inclined plate, making it convenient for the bolts to be transported and discharged after electrophoresis.

The electrophoresis pool 7 is filled with a mixture of paint, latex, rubber and other particles. After the electrophoresis pool 7 is energized, the paint, latex, rubber and other particles are evenly covered on the surface of the bolt, and the surface defects of the bolt are treated. During the electrophoresis treatment, the vibration motor 701 drives the inclined plate 703 to vibrate, which can drive the bolt to one side of the inclined plate 703, so as to facilitate the transport and discharge of the bolt after electrophoresis.

[0049] The workflow and principle of this invention are as follows: When processing bolt defects, the bolt is inserted into the vibratory feeder 108. The vibratory feeder 108 is vibrated by a motor at its bottom, causing the bolt to move to the outlet. Upon reaching the outlet, the bolt's rod-shaped portion faces downwards and falls into the guide tube 102. A guide member 103 is provided at the top of the guide tube 102 to facilitate the bolt's vertical fall. The inner wall of the guide tube 102 only allows for vertical bolt drop. The top of the clamp mounting frame 2 is connected to the guide tube 102. The bolt falls into the clamp mounting frame 2 and onto the fixed clamp 204. Two fixed clamps 204 are provided. Furthermore, the first lead screw 202 has reversed threads with the middle as the boundary. Two fixing clamps 204 are respectively installed at both ends of the first lead screw 202. The first motor 201 starts and drives the first lead screw 202 to rotate, which can drive the two fixing clamps 204 to open or close synchronously. When the two fixing clamps 204 are closed, the top of the bolt is fixed and the bolt rod is exposed at the bottom of the clamp mounting frame 2. The second motor 301 starts and drives the second lead screw 302 to rotate, which can drive the grinding part 304 to move, making it convenient to adjust the grinding size of the grinding part 304. The fixed positioning component drives the bolt to rotate, and the grinding part 304 grinds the bolt.
