Description

Technical Field

[0001] The utility model relates to the technical field of tapping machines, in particular to a metal fastener tapping machine. Background Art

[0002] The tapping machine is an efficient and precise mechanical equipment specially used to process precise internal threads on metal, plastic and other workpieces. It uses a high-speed rotating tap or tool to perform precise and efficient cutting operations at the specified position of the workpiece, and adjusts parameters such as rotation speed and feed speed to ensure that the generated thread size and shape meet strict industrial standards. Tapping machines are widely used in many fields such as machinery manufacturing, mold manufacturing, and automobile manufacturing. They are one of the indispensable and important tools in modern production lines. Their high-precision and high-efficiency processing capabilities have greatly improved the overall efficiency and product quality of industrial production.

[0003] Tapping machines are used in the manufacturing process of metal fasteners. Metal fasteners, such as screws and nuts, often need to be processed with threads inside to facilitate connection with other parts. Tapping machines use high-speed rotating cutting tools (such as taps) to cut precise threads on metal fasteners.

[0004] Patent document CN210231797U discloses a tapping machine, including a base and a mainboard arranged on the upper surface of the base, a support plate is arranged on the base and on one side of the mainboard, a tapping assembly is arranged on the support plate for lifting and lowering, the tapping assembly includes a lifting plate and a driving motor arranged on the lifting plate, a driving shaft is connected to the output end of the driving motor, one end of the driving shaft is connected to a tap after passing through the lifting plate, a lifting driving assembly for driving the lifting plate to lift and lower is arranged on the base, a through hole is passed through the mainboard from top to bottom, a mobile fastening assembly is arranged on the upper surface of the mainboard, the mobile fastening assembly includes a first driving cylinder and a second driving cylinder respectively arranged on the left and right sides of the through hole, the output ends of the first driving cylinder and the second driving cylinder are respectively connected to a first push rod and a second push rod, and the first push rod and the second push rod are respectively connected to the first extrusion plate and the second extrusion plate for cooperating with the extrusion fastening processing block at opposite ends. The utility model provides a tapping machine with a high safety factor and a stable fixed processing block.

[0005] As in the prior art of the above-mentioned patent, during the tapping process, the tapping machine will generate metal waste. These wastes are generated when the cutting tool cuts threads on the workpiece, and are composed of tiny particles of the workpiece material being cut off. Most tapping machines have a hair dryer in the working environment to blow away the cut metal debris, thereby ensuring that there will be no metal debris on the fixed table of the tapping machine to avoid affecting subsequent work. However, some waste will still adhere to the drill bit of the tapping machine, which cannot be processed by a hair dryer. If the debris and waste on the drill bit are not cleaned in time, it will affect the subsequent tapping work. Utility Model Content

[0006] The purpose of the utility model is to provide a metal fastener tapping machine to solve the above-mentioned deficiencies in the prior art.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a metal fastener tapping machine, comprising a support frame and a cylinder fixedly installed on the top of the support frame, the output end of the cylinder is transmission-connected with a lifting frame, the bottom end of the lifting frame is respectively fixedly installed with a tapping machine body and a stop block, two support columns are arranged below the support frame, the top of the two support columns are fixedly installed with a slide rail, two clamps are slidably installed inside the slide rail, the side walls of the two clamps are fixedly installed with connecting blocks, a tension spring is arranged inside the slide rail, the two ends of the tension spring are respectively fixedly connected to the clamps on both sides, the stop block is arranged between the two connecting blocks, one end of the two clamps are fixedly connected with two scraper rings, and the two scraper rings are arranged directly below the tapping machine body.

[0008] As a further description of the above technical solution: a fixed platform is arranged directly below the tapping machine body.

[0009] As a further description of the above technical solution: the top end of the stopper is provided with a wedge-shaped arc surface.

[0010] As a further description of the above technical solution: enclosures are arranged around the two scraper rings.

[0011] As a further description of the above technical solution: a magnetic attraction layer is arranged on the top of the two scraper rings.

[0012] As a further description of the above technical solution: magnetic plates are fixedly installed on the side walls of the two connecting blocks.

[0013] The utility model provides a metal fastener tapping machine. It has the following beneficial effects: the tapping machine body is the existing technology, and its function is that the cylinder drives the tapping machine body to tap the metal fastener below, and the cylinder drives the lifting frame to move downward. During the movement, the block slides between the two connecting blocks. When the block moves to a certain position, the drill bit of the tapping machine body is just above the two scraper rings, and the baffle leaves between the two connecting blocks. The two clamps move toward the middle under the action of the tension spring, so that the two scraper rings are in contact, and the tapping machine body continues to move downward under the action of the cylinder, and the scraper rings are moved to the middle. The scraper ring scrapes off the debris on the drill bit of the tapping machine body to prevent the debris and waste from affecting the subsequent tapping work. After the tapping is completed, the cylinder drives the lifting frame to move upward, the block pushes the two connecting blocks open, and the two scraper rings are separated to prevent the debris on the drill bit from being scraped off from the bottom of the scraper ring by the scraper ring, and then falling onto the fixed table below to avoid affecting the subsequent work. The debris is scraped to the top of the scraper ring only when the tapping machine body moves downward, and the debris above the scraper ring will not fall to the bottom and will not affect the tapping work.

[0014] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

[0015] This application document provides an overview of various implementations or examples of the technology described in the present disclosure, and is not a comprehensive disclosure of the entire scope or all features of the disclosed technology. BRIEF DESCRIPTION OF THE DRAWINGS
