Technical Field
[0001] This utility model belongs to the field of drill bit grinding technology, specifically relating to a drill bit grinding assembly for valve drilling. Background Technology
[0002] The function of a valve is specifically to introduce air into the engine and expel exhaust gases after combustion. A valve consists of a valve head and a stem, and its shape resembles a screw. Valve manufacturing requires various cutting machine tools, testing devices, and other equipment. During use, damage and wear of parts are inevitable, affecting component installation, sometimes necessitating drilling or other machining processes.
[0003] However, existing drill bit components require manual hand-holding and grinding with a grinder, resulting in decreased grinding accuracy and posing certain risks to the operation. Furthermore, existing drill bit clamping tools often lack angle adjustment capabilities, requiring the drill bit to be disassembled and re-clamped, causing inconvenience during use. Therefore, there is an urgent need for a drill bit grinding component for valve drilling to solve the above problems. Utility Model Content
[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a drill bit grinding component for valve drilling, so as to solve the problems mentioned in the background art, which are that the existing drill bit part is ground by manual hand-held drill bit, resulting in a decrease in grinding accuracy, and the existing drill bit clamping tools often do not have the function of adjusting the angle, causing inconvenience during use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a drill bit grinding assembly for valve drilling, comprising a worktable, a grinding machine body, a clamping structure, and a rotating structure. The top of the worktable is fixedly connected to the grinding machine body. The clamping structure includes a base, and the top of the base is fixedly connected to four sliding rods. The four sliding rods are slidably connected to a sliding plate. The top right end of the base is rotatably connected to a threaded rod, which is threadedly connected to the sliding plate. The rotating structure includes a first clamping plate and a second clamping plate. The bottom of the sliding plate is rotatably connected to the first clamping plate, and the top of the base is rotatably connected to the second clamping plate. The bottom of the second clamping plate is fixedly connected to a worm gear, which meshes with a worm. The worm is rotatably connected to the base.
[0006] Preferably, the bottom of the workbench is fixedly connected to four support legs.
[0007] Preferably, the top of the clamping plate is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the sliding plate.
[0008] Preferably, a handle is fixedly connected to the top of the threaded rod.
[0009] Preferably, a second grip is fixedly connected to the right side of the worm gear.
[0010] Preferably, the bottom of the clamping plate is fixedly connected to the rotating shaft, the rotating shaft is rotatably connected to the base, and the bottom outer wall of the base is fixedly connected to the worm gear.
[0011] Preferably, both the first clamping plate and the second clamping plate are provided with rubber pads on the side near the middle, and the surface of the rubber pads is provided with uneven patterns.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The valve drilling tool grinding assembly is equipped with a clamping structure. The drill bit is placed on the clamping plate 2, and the handle 1 is rotated to drive the threaded rod to rotate. The threaded rod drives the sliding plate to move downward, and the sliding plate drives the clamping plate 1 to move downward. The clamping plate 1 and clamping plate 2 clamp the drill bit. The clamping structure can clamp the drill bit and can clamp drill bits of different sizes, which improves applicability and facilitates use.
[0014] 2. This valve drilling drill grinding assembly features a rotating structure. When the drill bit angle needs adjustment, rotating the second handle causes the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the second rotating shaft, which in turn drives the second clamping plate to rotate. The clamping plate then drives the drill bit to rotate. The friction between the drill bit and the first clamping plate also drives the first clamping plate to rotate. The self-locking mechanism between the worm wheel and the worm gear fixes the position of the second clamping plate. The rotating structure allows for free adjustment of the drill bit angle, enabling quick and easy adjustment of the grinding angle. This design is convenient, fast, and easy to operate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 This utility model provides an embodiment of a drill bit grinding assembly for valve drilling, comprising a worktable 1, a grinding machine body 2, a clamping structure 3, and a rotating structure 4. The top of the worktable 1 is fixedly connected to the grinding machine body 2. The clamping structure 3 includes a base 31, and the top of the base 31 is fixedly connected to four sliding rods 33. The four sliding rods 33 are slidably connected to a sliding plate 32. The top right end of the base 31 is rotatably connected to a threaded rod 34, which is threadedly connected to the sliding plate 32. The rotating structure 4 includes a first clamping plate 42 and a second clamping plate 44. The bottom of the sliding plate 32 is rotatably connected to the first clamping plate 42, and the top of the base 31 is rotatably connected to the second clamping plate 44. The bottom of the second clamping plate 44 is fixedly connected to a worm gear 45, which meshes with a worm 46. The worm 46 is rotatably connected to the base 31. The position of the second clamping plate 44 is fixed by the self-locking property between the worm gear 45 and the worm 46.
[0023] Furthermore, four support legs 11 are fixedly connected to the bottom of the workbench 1 to support the workbench 1.
[0024] Furthermore, the top of the clamping plate 42 is fixedly connected to the rotating shaft 41, and the rotating shaft 41 is rotatably connected to the sliding plate 32. The rotating shaft 41 allows the sliding plate 32 and the clamping plate 42 to rotate relative to each other. When the drill bit rotates, the friction between the drill bit and the clamping plate 42 can drive the clamping plate 42 to rotate.
[0025] Furthermore, a handle 35 is fixedly connected to the top of the threaded rod 34. Rotating the handle 35 causes the threaded rod 34 to rotate, which in turn causes the sliding plate 32 to move downward.
[0026] Furthermore, a second handle 47 is fixedly connected to the right side of the worm 46. Rotating the second handle 47 causes the worm 46 to rotate, which in turn causes the worm wheel 45 to rotate.
[0027] Furthermore, the bottom of the clamping plate 2 44 is fixedly connected to the rotating shaft 2 43, the rotating shaft 2 43 is rotatably connected to the base 31, and the bottom outer wall of the base 31 is fixedly connected to the worm gear 45. The worm gear 45 drives the rotating shaft 2 43 to rotate, the rotating shaft 2 43 drives the clamping plate 2 44 to rotate, and the clamping plate 2 44 drives the drill bit to rotate.
[0028] Furthermore, both clamping plate 42 and clamping plate 44 are provided with rubber pads on the side near the middle, and the surface of the rubber pads is provided with uneven patterns. The rubber pads can increase the friction between clamping plate 42 and clamping plate 44 and the drill bit, thereby improving the stability during clamping.
[0029] Working principle:
[0030] In use, place the drill bit on clamping plate 44, rotate handle 35 to rotate threaded rod 34, which in turn moves sliding plate 32 downwards, causing clamping plate 42 to move downwards. Clamping plates 42 and 44 then hold the drill bit. The clamping structure 3 can hold drill bits of different sizes, improving versatility and ease of use. When adjusting the drill bit angle, rotate handle 47 to rotate the worm gear. When rod 46 rotates, worm gear 46 drives worm wheel 45 to rotate, which in turn drives shaft 43 to rotate. Shaft 43 drives clamping plate 44 to rotate, which in turn drives drill bit to rotate. The friction between drill bit and clamping plate 42 causes clamping plate 42 to rotate. The self-locking mechanism between worm wheel 45 and worm gear 46 fixes the position of clamping plate 44. The angle of drill bit can be freely adjusted by rotating structure 4, which allows for quick and easy adjustment of the drill bit's grinding angle. This makes the operation convenient and quick.
