Technical Field
[0001] This utility model belongs to the field of drilling assistance technology, and relates to a special blown film machine for mulch film, especially a drilling assistance device for tire pressure sensors. Background Technology
[0002] Drilling aids for tire pressure sensors are typically used to precisely drill holes in the wheel rim, rather than directly manipulating the tire pressure sensor itself. The tire pressure sensor is designed to be installed inside the wheel rim, and its main function is to monitor tire pressure in real time and transmit the acquired data to the vehicle's monitoring system. This crucial technology not only enhances driving safety but also effectively helps drivers obtain timely information about tire conditions, thereby avoiding potential risks. Through this sophisticated monitoring mechanism, the vehicle can maintain optimal performance and safety during driving, providing drivers with a more reassuring driving experience.
[0003] When installing a tire pressure sensor, the wheel hub usually needs to be fixed first, and then drilling is performed. During the drilling process, burrs will be generated at the hole, which need to be ground off. Generally, the drill bit is fixed, and changing the drill bit is troublesome, time-consuming, and laborious. Therefore, there is an urgent need for a drilling auxiliary device for tire pressure sensors to solve this problem. Utility Model Content
[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a drilling auxiliary device for tire pressure sensors. The technical problem this utility model aims to solve is: how to drill holes in wheel hubs and facilitate the replacement of drill bits.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A drilling auxiliary device for tire pressure sensors includes a workbench. The top of the workbench is equipped with a fixing mechanism for fixing the wheel hub. An L-shaped mounting bracket is fixed to one end of the top of the workbench. A drill bit is placed on the inner wall of the L-shaped mounting bracket, and a quick-release mechanism for quickly changing the drill bit is provided inside the L-shaped mounting bracket. The quick-release mechanism includes a second rotating rod. Elastic threaded plates are installed around the bottom of the second rotating rod, and a first threaded groove communicating with the external thread of the elastic threaded plate is opened on the bottom of the outer wall of the second rotating rod. A matching fixing sleeve is provided on the outer wall of the elastic threaded plate, and a communicating trapezoidal threaded groove is opened on the top and bottom of the inner wall of the fixing sleeve. The top of the drill bit is located inside multiple elastic threaded plates.
[0007] The working principle of this utility model is as follows: through the cooperation of the fixed sleeve and the elastic threaded plate, the bottom of the elastic threaded plate can be gradually squeezed or gradually increased, and the drill bit can be clamped and disassembled, so as to achieve the effect of quick disassembly and replacement of the drill bit.
[0008] A cylinder is mounted on the top of the L-shaped mounting bracket, and a protective cover is fixed to the top of the cylinder through the inner wall of the L-shaped mounting bracket.
[0009] A second motor is installed at the bottom of the inner wall of the protective cover, and a second rotating rod is rotatably connected to the bottom of the protective cover. The output shaft of the second motor is fixedly connected to the top of the second rotating rod.
[0010] The protective cover has multiple interconnected ventilation holes on both sides.
[0011] With the above structure, the second motor can drive the drill bit to rotate and drill holes in the hub, and the second motor can be protected by a protective cover;
[0012] The fixing mechanism includes a turntable, with clamping plates at both ends of the top of the turntable. One of the clamping plates is fixed to one end of the top of the turntable, and anti-slip pads are installed on the sides of the two clamping plates that are close to each other.
[0013] A fixing plate is fixed to the other end of the top of the turntable, and an electric push rod is installed on the end of the fixing plate away from the clamping plate. The output shaft of the electric push rod is fixedly connected to the outer wall of one of the clamping plates. Two guide rods are fixed to the end of one of the clamping plates near the electric push rod, and holes for the guide rods to pass through are opened on both sides of the fixing plate.
[0014] The top of the workbench is rotatably connected to a first rotating rod, and the turntable is fixed to the outer wall of the first rotating rod. The bottom of the workbench is equipped with a first motor, and the output shaft of the first motor is fixedly connected to the bottom of the first rotating rod.
[0015] With the above structure, the electric push rod can push one of the clamping plates and bring it close to the outer surface of the other end of the hub, thus facilitating the clamping and fixing of the hub. Then, the first motor can drive the turntable to rotate, which in turn drives the hub to rotate, making it convenient to drill holes at different positions on the hub.
[0016] Compared with the prior art, the drilling auxiliary device for the tire pressure sensor of this utility model has the following advantages:
[0017] 1. In this utility model, by rotating the fixed sleeve and gradually moving the trapezoidal thread groove away from the elastic thread plate, the elastic thread plate is released and the fixing of the drill bit is loosened. Then, the matching grinding head is placed between multiple elastic thread plates. Then, by rotating the fixed sleeve and matching the trapezoidal thread groove with the thread on the outer wall of the elastic thread plate, the trapezoidal thread groove will gradually squeeze the bottom of the elastic thread plate, thereby achieving the effect of quick replacement of the drill bit. This facilitates the grinding and trimming of burrs at the hole of the wheel hub, saves the time of replacing the drill bit, and improves the efficiency of drilling holes in the wheel hub.

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0024] like Figures 1-4As shown, the tire pressure sensor drilling auxiliary equipment includes a workbench 1. The top of the workbench 1 is equipped with a fixing mechanism for securing the wheel hub. An L-shaped mounting bracket 3 is fixed to one end of the top of the workbench 1. A drill bit 302 is mounted on the top of the inner wall of the L-shaped mounting bracket 3. The top of the inner wall of the L-shaped mounting bracket 3 is equipped with a quick-release mechanism for quickly replacing the drill bit 302. The quick-release mechanism includes a second rotating rod 304. Elastic threaded plates 306 are installed around the bottom of the second rotating rod 304. A first threaded groove 305 communicating with the external thread of the elastic threaded plates 306 is opened on the bottom of the outer wall of the second rotating rod 304. A matching fixing sleeve 303 is provided on the outer wall of the elastic threaded plates 306. A trapezoidal threaded groove 310 communicating between the top and bottom of the inner wall of the fixing sleeve 303 is opened. The top of the drill bit 302 is located inside multiple elastic threaded plates 306. A cylinder 301 is mounted on the top of the L-shaped mounting bracket 3. The output shaft of the cylinder 301 passes through the top of the inner wall of the L-shaped mounting bracket 3 and is fixed with a protective cover 307. A second motor 308 is installed at the bottom of the inner wall of the protective cover 307. A second rotating rod 304 is rotatably connected to the bottom of the protective cover 307, and the output shaft of the second motor 308 is fixedly connected to the top of the second rotating rod 304. Multiple interconnected ventilation holes 309 are provided on both sides of the protective cover 307. The fixing mechanism includes a turntable 2. Clamping plates 202 are provided at both ends of the top of the turntable 2. One clamping plate 202 is fixed to one end of the top of the turntable 2. Anti-slip pads 203 are installed on the sides of the two clamping plates 202 that are close to each other. A fixing plate 201 is fixed to the other end of the top of the turntable 2. An electric push rod 204 is installed at the end of the fixing plate 201 away from the clamping plate 202. The output shaft of the electric push rod 204 is fixedly connected to the outer wall of one of the clamping plates 202. Two guide rods 205 are fixed to the end of one of the clamping plates 202 that is close to the electric push rod 204. Holes for the guide rods 205 to pass through are provided on both sides of the fixing plate 201. The top of the workbench 1 is rotatably connected to a first rotating rod 206, and the turntable 2 is fixed to the outer wall of the first rotating rod 206. The bottom of the workbench 1 is equipped with a first motor 207, and the output shaft of the first motor 207 is fixedly connected to the bottom of the first rotating rod 206.
[0025] The working principle of this utility model is as follows: In use, first place the wheel hub to be drilled on top of the turntable 2, ensuring one end surface of the hub is pressed against one of the clamping plates 202. Then, operate the electric push rod 204. The electric push rod 204 will drive the other clamping plate 202 closer to the other end surface of the hub. The clamping plate 202 will then drive the guide rod 205 closer to the hub, clamping and fixing it. At this time, the anti-slip pad 203 will prevent the hub from slipping and make it more stable. Then, operate the first... Motor 207 drives the first rotating rod 206 to rotate, which in turn drives the turntable 2 to rotate, simultaneously rotating the hub. The hub is rotated to the position where drilling is needed, positioned below the drill bit 302. Then, cylinder 301 is activated, causing the protective cover 307 to move downwards. This then starts the second motor 308, which drives the second rotating rod 304 to rotate, simultaneously rotating the fixing sleeve 303. The fixing sleeve 303 then rotates the drill bit 302. The cylinder 301 drives the drill bit 302 downwards, gradually approaching the position on the wheel hub where a hole needs to be drilled. After drilling, the cylinder 301 moves the drill bit 302 away from the wheel hub. At this point, there are some burrs at the hole, requiring the replacement of the grinding head to grind them down. Then, the cylinder 301 and the second motor 308 are stopped. The fixed sleeve 303 is then rotated away from the elastic threaded plate 306. Because the trapezoidal thread groove 310 on the inner wall of the fixed sleeve 303 is trapezoidal from top to bottom... As the trapezoidal thread groove 310 gradually moves away from the elastic thread plate 306, the elastic thread plate 306 will reset and loosen its fixation on the drill bit 302. Then, a grinding head adapted to the hole is placed between the inner walls of the multiple elastic thread plates 306. The trapezoidal thread groove 310 then engages with the elastic thread plate 306, and the trapezoidal thread groove 310 gradually squeezes the elastic thread plate 306 until the grinding head is fixed. The above operation is then repeated to grind the burrs at the hole.
[0026] In summary, in this invention, by rotating the fixing sleeve 303 and gradually moving the trapezoidal thread groove 310 away from the elastic thread plate 306, the elastic thread plate 306 is released, loosening the fixation on the drill bit 302. Then, the matching grinding head is placed between multiple elastic thread plates 306. By rotating the fixing sleeve 303 and matching the trapezoidal thread groove 310 with the thread on the outer wall of the elastic thread plate 306, the trapezoidal thread groove 310 gradually squeezes the bottom of the elastic thread plate 306, thereby achieving the effect of quickly replacing the drill bit 302. This facilitates the grinding and trimming of burrs at the wheel hub hole, saves time in replacing the drill bit 302, and improves the efficiency of drilling the wheel hub.
