Description

Technical Field

[0001] This utility model belongs to the technical field of cylinder repair devices, and in particular relates to a portable tapping jig for repairing threaded holes in motorcycle cylinders. Background Technology

[0002] According to the published patent CN208357849U, a machine for machining screw holes in motorcycle cylinder blocks includes a frame, a machining panel mounted on the frame, a support frame mounted on the frame, a drill bit mounted on the support frame, a chip removal chamber mounted on the machining panel, a lifting groove mounted on the support frame, and a lifting slider mounted within the lifting groove. The structure is reasonably designed and can not only perform drilling operations but also compress and shorten rising filamentous or strip-shaped chips, preventing them from rising and tangling around the drill bit. However, it still has the following shortcomings: While the aforementioned equipment can drill holes in cylinders, the cylinder's position is not fixed, and displacement may occur during the drilling process, resulting in insufficient drilling accuracy or even failure to drill properly, thus affecting cylinder repair. Therefore, we propose a portable tapping jig for repairing threaded holes in motorcycle cylinders. Utility Model Content

[0003] The purpose of this utility model is to provide a portable tapping jig for repairing threaded holes in motorcycle cylinders. Through the fixing mechanism and the installation mechanism, it solves the problem that although the above-mentioned equipment can drill holes in the cylinder, the cylinder may shift during the drilling process due to the non-fixed position of the cylinder, resulting in insufficient drilling accuracy or even failure to drill normally, thus affecting the repair of the cylinder.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a portable tapping chuck for repairing threaded holes in motorcycle cylinders, including a carrying case. A connecting plate is fixedly connected to the inner wall of the carrying case, and a fixing mechanism is provided on the outer wall of the connecting plate. The fixing mechanism includes a first motor, the bottom output end of which is fixedly connected to a worm gear via a coupling. An annular limiting block is fixedly connected to the top outer wall of the connecting plate. A gear is rotatably connected to the top outer wall of the annular limiting block. A worm gear is fixedly connected to the outer wall of the gear. Several racks are slidably connected to the inner wall of the annular limiting block. Several fixed shafts are fixedly connected to the top outer wall of the connecting plate near the racks. Gears are rotatably connected to the outer walls of the fixed shafts. An annular limiting block is fixedly connected to the top outer wall of the connecting plate near the fixed shafts. A top plate is fixedly connected to the outer walls of the racks. An installation mechanism is provided on the outer wall of the connecting plate.

[0005] Furthermore, the outer wall of the first motor is fixedly connected to the outer wall of the connecting plate, the outer wall of the worm gear meshes with the outer wall of the worm, the outer walls of several gears mesh with the outer walls of the gears, and the outer walls of several racks are slidably connected to the inner wall of the annular limiting block.

[0006] Furthermore, the mounting mechanism includes a plurality of threaded rods, the outer walls of which are rotatably connected to the inner wall of the connecting plate.

[0007] Furthermore, the outer walls of several threaded rods are threadedly connected to sliders, and the inner walls of several sliders are fixedly connected to electric telescopic rods.

[0008] Furthermore, a fixing plate is fixedly connected to the top output end of the electric telescopic rod, and a second motor is fixedly connected to the bottom outer wall of the fixing plate.

[0009] Furthermore, each of the threaded rods has a pulley two fixedly connected to its outer wall, and the outer wall of the pulley two is connected to a belt for transmission.

[0010] Furthermore, the bottom output end of the second motor is fixedly connected to a drive shaft via a coupling, and a plug is inserted into the inner wall of the drive shaft, while a tap is inserted into the outer wall of the plug.

[0011] Furthermore, a spring is fixedly connected to the bottom outer wall of the drive shaft, and a protective cover is fixedly connected to the bottom outer wall of the spring. The inner wall of the protective cover is slidably connected to the outer wall of the insertion rod.

[0012] This utility model has the following beneficial effects: 1. This utility model incorporates a second gear on a fixed shaft. When the equipment is in use, starting the first motor causes the worm gear to rotate, which in turn causes the worm wheel to rotate. The rotation of the worm wheel causes the gear to rotate on the annular limiting block. The rotation of the gear causes the second gear to rotate on the fixed shaft. The rotation of the second gear causes the rack at the lower end to move, allowing the rack to slide within the annular limiting block and the second annular limiting block. This achieves the goal of fixing the position of the cylinder during tapping repair, preventing displacement or even detachment of the cylinder, which would lead to failure of the tapping repair.

[0013] 2. This utility model incorporates an electric telescopic rod within the slider. When it is necessary to control the tap to tap different positions on the cylinder, the cylinder can be released and its position adjusted. Simultaneously, the threaded rod can be rotated. The rotation of the threaded rod drives the second pulley on the left to rotate, causing the belt to rotate. The belt rotation drives the second pulley on the right to rotate, which in turn drives the threaded rod on the right to rotate. The rotation of the threaded rod causes the slider to slide within the connecting plate, facilitating user adjustment of the tap's position and expanding the device's applicability. Furthermore, the tap is easy to install and remove without the need for other tools, and it is convenient to replace or maintain after wear and tear from prolonged use.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-7 As shown, this utility model is a portable tapping chuck for repairing threaded holes in motorcycle cylinders, including a carrying case 1. A connecting plate 101 is fixedly connected to the inner wall of the carrying case 1, and a fixing mechanism 2 is provided on the outer wall of the connecting plate 101. Through the connecting plate 101, the positions of the slider 302 and the annular limiting block 203 can be fixed, so that the slider 302 can only slide within the connecting plate 101. The fixing mechanism 2 includes a first motor 201. A worm gear 202 is fixedly connected to the bottom output end of the first motor 201 via a coupling. An annular limiting block 203 is fixedly connected to the top outer wall of the connecting plate 101. A gear 204 is rotatably connected to the top outer wall of the annular limiting block 203. The annular limiting block 203 can limit the position of the gear 204, ensuring that the gear 204 can only rotate within the annular limiting block 203, and preventing the gear 204 from falling off. A worm wheel 205 is fixedly connected to the outer wall of the gear 204. Several racks 206 are slidably connected to the inner wall of the annular limiting block 203. The end of the connecting plate 101 near the racks 206... Several fixed shafts 207 are fixedly connected to the top outer wall. The position of the gear 208 can be fixed by the fixed shafts 207, so that it can only rotate on the fixed shafts 207. The gear 208 is rotatably connected to the outer wall of the several fixed shafts 207. The annular limiting block 209 is fixedly connected to the top outer wall of the connecting plate 101 near the fixed shafts 207. The top plate 210 is fixedly connected to the outer wall of the several racks 206. The outer wall of the connecting plate 101 is provided with an installation mechanism 3. The friction between the rack 206 and the cylinder can be increased by the top plate 210 because the material of the top plate 210 has a certain elasticity.

[0020] The outer wall of the first motor 201 is fixedly connected to the outer wall of the connecting plate 101. The outer wall of the worm gear 205 meshes with the outer wall of the worm 202. The outer walls of several gears 208 mesh with the outer walls of gears 204. The outer walls of several racks 206 are slidably connected to the inner wall of the annular limiting block 209. The mounting mechanism 3 includes several threaded rods 301. The position of the slider 302 can be limited by the threaded rods 301. When the threaded rods 301 rotate, they can drive the slider 302 to move within the connecting plate 101. The outer walls of several threaded rods 301 are rotatably connected to the inner wall of the connecting plate 101. The outer walls of several threaded rods 301 are threadedly connected to sliders 302. The inner walls of several sliders 302 are fixedly connected to electric telescopic rods 303. The top output end of the electric telescopic rod 303 is fixedly connected to a fixing plate 304. When the user starts the electric telescopic rod 303, the electric telescopic rod 303 will raise or lower the fixing plate 304.

[0021] A second motor 305 is fixedly connected to the bottom outer wall of the fixed plate 304. A pulley 306 is fixedly connected to the outer wall of several threaded rods 301. A belt 307 is driven to the outer wall of the pulley 306. A drive shaft 312 is fixedly connected to the bottom output end of the second motor 305 through a coupling. When the second motor 305 rotates, it can drive the drive shaft 312 to rotate. The rotation of the drive shaft 312 will drive the insertion rod 308 to rotate. The insertion rod 308 is inserted into the inner wall of the drive shaft 312. A tap 309 is inserted into the outer wall of the insertion rod 308. A spring 310 is fixedly connected to the bottom outer wall of the drive shaft 312. A protective cover 311 is fixedly connected to the bottom outer wall of the spring 310. The inner wall of the protective cover 311 is slidably connected to the outer wall of the insertion rod 308. The protective cover 311 can limit the position of the insertion rod 308 and prevent it from falling off.

[0022] One specific application of this embodiment is: When the operator needs to use the equipment, they open the carrying case 1, place the individual cylinder between the top plates 210, and then start the first motor 201. The rotation of the first motor 201 drives the worm gear 202 to rotate, causing the worm wheel 205 to rotate. The rotation of the worm wheel 205 drives the gear 204 to rotate on the annular limit block 203. When the gear 204 rotates, it drives the second gear 208 to rotate on the fixed shaft 207. When the second gear 208 rotates, it drives the lower rack 206 to move, which in turn allows the rack 206 to slide within the annular limit block 203 and the second annular limit block 209. When the rack 206 moves, it drives the top plate 210 to move. When the top plate 210 is pressed against the outer wall of the cylinder, the position of the cylinder can be fixed. Then, the second motor 305 is started to rotate the transmission shaft 312. The rotation of the transmission shaft 312 drives the insertion rod 308 to rotate the tap 309. Then, the electric telescopic rod 303 is started to fix the plate. As tap 304 gradually decreases, it lowers tap 309 to tap the cylinder. When tap 309 needs to tap different positions on the cylinder, the cylinder can be released and its position adjusted. Simultaneously, threaded rod 301 can be rotated. When threaded rod 301 rotates, it drives pulley 306 on the left to rotate, causing belt 307 to rotate. Belt 307 rotates, which drives pulley 306 on the right to rotate, which in turn drives threaded rod 301 on the right to rotate. When threaded rod 301 rotates, it drives slider 302 to slide within connecting plate 101, thereby adjusting the overall position of the second motor 305. When tap 309 wears out after prolonged use, first lift protective cover 311 to compress spring 310. Then, insert rod 308 can be directly removed from between drive shaft 312 and tap 309. Tap 309 can then be removed for replacement or maintenance.
