Description
Technical Field
[0001] This utility model relates to the field of polishing equipment technology, and in particular to a polishing device for drill bit production. Background Technology
[0002] A drill bit is a cutting tool used in drills or drilling machines to cut circular holes. The basic principle of a drill bit is to rotate its cutting edge, cut the workpiece, and then remove drill chips through the drill groove. Commonly used drill bits include twist drills, flat drills, center drills, deep hole drills, and casing drills. Carbide drill bits generally refer to cemented carbide drill bits, which require polishing during the manufacturing process.
[0003] Existing drill bit polishing technology cannot meet the requirements for clamping drill bits of different diameters, thereby reducing the multi-functionality of the equipment, resulting in resource waste, reduced equipment productivity, and thus affecting processing speed. Summary of the Invention
[0004] The problem to be solved by this utility model is to provide a polishing device for drill bit production, which addresses the shortcomings of the prior art.
[0005] To solve the above problems, the present invention adopts the following solution: a polishing device for drill bit production, comprising a clamping mechanism, a grinding mechanism, and a moving mechanism; the clamping mechanism is located on the left side of the grinding mechanism, and the moving mechanism is located on the left side of the grinding mechanism.
[0006] The clamping mechanism includes a lower clamping plate with a clamping groove at the top. A fixing post is fixedly connected to the top of the lower clamping plate. An upper clamping plate is slidably connected to the outer wall of the fixing post. A fixing plate is fixedly connected to the end of the fixing post away from the lower clamping plate. An inner groove is formed inside the upper clamping plate. A slider is rotatably connected to the outer wall of the inner groove. A threaded rod is fixedly connected to the top of the slider. A handle is fixedly connected to the end of the threaded rod away from the slider.
[0007] The above technical solution involves placing the drill bit whose end face needs polishing on the surface of the clamping groove. The worker then rotates the handle to rotate the threaded rod. The threaded rod is connected to the fixed plate by threads, and it rotates inside the upper clamping plate via a slider. When the threaded rod moves downward, it causes the upper clamping plate to slide along the outer wall of the fixed column, thereby clamping the drill bit. The threaded rod not only has a certain self-locking function to prevent loosening during polishing, but also allows for end face polishing of drill bits of different diameters by adjusting the distance between the upper and lower clamping plates.
[0008] As a further improvement to the above solution, two clamping slots are provided, and the clamping plates below the two clamping slots are symmetrically arranged. Two fixing columns are provided, and the clamping plates below the two fixing columns are symmetrically arranged.
[0009] As a further improvement to the above solution, the grinding mechanism includes a worktable, a support base fixedly connected to the top of the worktable, a protective plate fixedly connected to the top of the worktable, and a fixing block fixedly connected to the top of the worktable.
[0010] As a further improvement to the above solution, a fixing block is fixedly connected to the top of the workbench, a motor is fixedly connected to the top of the support base, a connecting rod is fixedly connected to the output end of the motor, a wheel is fixedly connected to the outer wall of the connecting rod, and a belt is rotatably connected to the outer wall of the wheel.
[0011] As a further improvement to the above solution, a first rotating wheel is rotatably connected to the inner wall of the belt, a rotating rod is fixedly connected to the right side of the first rotating wheel, the rotating rod passes through the fixed block and is rotatably connected inside the fixed block, and a grinding disc is fixedly connected to the outer wall of the rotating rod.
[0012] With the above technical solution, the motor drives the rotating wheel to rotate through the connecting rod, and the rotating wheel drives the first rotating wheel to rotate through the belt. The first rotating wheel is fixedly connected to the rotating rod, and the grinding disc is fixed on the outer wall of the rotating rod, so that the grinding disc rotates, which facilitates grinding. At the same time, the protective plate can prevent the debris generated by the grinding disc during the rotation grinding process from flying and prevent injury to workers.
[0013] As a further improvement to the above solution, the moving mechanism includes a T-shaped slide groove, which is opened on the top of the worktable. A limit plate is fixedly connected to the inner wall of the worktable, and a threaded rod is threadedly connected inside the limit plate.
[0014] As a further improvement to the above solution, a handle is fixedly connected to one end of the threaded rod near the limiting plate, and the other end of the threaded rod away from the limiting plate is rotatably connected to the inside of the workbench. A fixing block is threadedly connected to the threaded rod, and the fixing block is fixedly connected to the bottom of the lower clamping plate. A T-shaped slider is fixedly connected to the bottom of the lower clamping plate, and the T-shaped slider is slidably connected to the outer wall of the T-shaped groove.
[0015] With the above technical solution, the worker moves the fixed block 2 by using handle 1. The fixed block 2 is fixedly connected to the lower clamping plate. A T-shaped slider is fixed at the bottom of the lower clamping plate. The T-shaped slider slides on the outer wall of the T-shaped groove, thereby ensuring the stability of the lower clamping plate during movement. Handle 1 allows the drill bit end face to slowly contact the grinding disc, protecting the worker's hands.
[0016] The technical effects of this utility model are as follows: This utility model first places the drill bit whose end face needs to be polished on the surface of the clamping groove. At this time, the worker rotates the handle to drive the threaded rod to rotate. The threaded rod is connected to the fixed plate by threads, and at the same time, the threaded rod rotates inside the upper clamping plate through the slider. When the threaded rod moves downward, it drives the upper clamping plate to slide along the outer wall of the fixed column, thereby clamping the drill bit. The threaded rod not only has a certain self-locking ability to prevent loosening during the polishing process, but also allows for end face polishing of drill bits of different diameters by adjusting the distance between the upper and lower clamping plates.
[0017] This invention uses a motor to drive a rotating wheel via a connecting rod. The rotating wheel is driven by a belt to rotate another rotating wheel. The first rotating wheel is fixedly connected to a rotating rod, and a grinding disc is fixed on the outer wall of the rotating rod, thereby allowing the grinding disc to rotate for easy grinding. At the same time, the protective plate can prevent the debris generated during the grinding process from flying and causing injury to workers. Attached Figure Description
