Description

Technical Field

[0001] This utility model relates to the field of automotive exhaust pipe processing technology, specifically to a quick positioning and clamping device for automotive exhaust pipe bodies. Background Technology

[0002] The exhaust pipe is part of the car engine's exhaust system. It is responsible for guiding the exhaust gases produced by engine combustion from the cylinder to the outside of the vehicle. During the processing of the exhaust pipe, positioning fixtures are used to fix and limit the exhaust pipe, which makes it convenient for users to perform processing operations to fix the exhaust pipe in a fixed position.

[0003] Publication No. CN216327806U discloses a clamping mechanism for processing automotive exhaust pipes. This device places the automotive exhaust pipe between a first clamp and a second clamp. The position of the first and second clamps can be adjusted via a connecting rod using a connecting bolt, allowing for the use of exhaust pipes of different diameters. The user can lock the connecting bolt of the first clamp by rotating a threaded cap, thereby adjusting the installation position of the second clamp and fixing it in a fixed state after adjustment. However, this patent still has the following problems in practical use:

[0004] The device, through the setting of the fixed clamp, enables the clamping mechanism for processing automobile exhaust pipes to have a fixed and adjustable structure, allowing it to flexibly install exhaust pipes of different diameters. However, the device's fixing cap, connecting rod, spring clip, and other structures are close to the exhaust pipe, which may cause debris to fly onto the surface of the structure when the worker uses a grinding equipment to grind the exhaust pipe. This greatly reduces the service life of the device and may cause jamming, causing inconvenience to the worker during use.

[0005] A quick positioning and clamping device for automotive exhaust pipes is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a quick positioning and clamping device for automotive exhaust pipes, in order to solve the problem mentioned in the background art. Currently, the clamping mechanism for processing automotive exhaust pipes has a fixed and adjustable structure through the setting of fixed clamps, which allows for flexible installation of exhaust pipes of different diameters. However, the structure of this device, such as the fixing cap, connecting rod, and spring cap, is close to the exhaust pipe. As a result, when workers use grinding equipment to grind the exhaust pipe, debris may be splashed onto the surface of the structure, which greatly reduces the service life of the device and may cause jamming.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick positioning and clamping device for an automobile exhaust pipe, comprising a support frame, a support plate slidably connected to the upper interior of the support frame, and a base fixedly connected to the bottom of the support frame; a clamping mechanism is provided on one side of the support plate, and a limit component is provided inside the clamping mechanism;

[0008] The clamping mechanism includes a circular box disposed on the top side of the support plate. A drive rod is rotatably connected inside one side of the circular box, and a circular plate is fixedly connected to one end of the drive rod. Movable rods are rotatably connected to the side of the circular plate away from the center. U-shaped plates are slidably connected inside the circular box. The end of the movable rod away from the circular plate is rotatably connected to the U-shaped plate. A limit plate is fixedly connected to the side of the circular box away from the support plate. One end of the U-shaped plate passes through the limit plate and is slidably connected to the limit plate. An arc-shaped plate is fixedly connected to one end of the U-shaped plate, and a rubber pad is embedded on the inner side of the arc-shaped plate.

[0009] Preferably, a limiting rod is fixedly connected to one side of the arc-shaped plate, and one end of the limiting rod passes through the limiting plate and is slidably connected to the limiting plate. A stop block is fixedly connected to the end of the limiting rod away from the arc-shaped plate.

[0010] Preferably, a rotating tube is fixedly connected to the side of the round box away from the U-shaped plate, and one end of the rotating tube passes through the support plate and is rotatably connected to the support plate. The drive rod is welded with threaded teeth on the outside of the side away from the round box, and a threaded seat is threadedly connected to the outside of the threaded teeth.

[0011] Preferably, the limiting component includes a limiting box fixedly installed on one side of the top of the support plate, and a toothed ring is welded to the outside of the rotating tube. A sliding rod is slidably connected inside the limiting box, and a sliding plate is fixedly connected to the bottom of the sliding rod. The bottom of the sliding plate is welded with teeth, and the teeth are engaged with the outside of the toothed ring. A retractable rod is symmetrically fixedly connected between the inside of the limiting box and the sliding plate, and a retractable spring is sleeved on the outside of the retractable rod.

[0012] Preferably, a rotating handle is fixedly connected to the end of the drive rod away from the support plate.

[0013] Preferably, a fixing knob is threadedly connected to one side of the support frame, and threaded grooves are provided on one side of the support plate, with the outside of the fixing knob and the inside of the threaded groove being threadedly connected.

[0014] Preferably, the outer side of the skateboard is slidably connected to the inner side of the limiting box.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A quick positioning and clamping device for an automotive exhaust pipe is described below: The operator rotates a drive rod to rotate a circular plate in both directions. The rotation of the circular plate causes multiple sets of movable rods to rotate. The rotation of the movable rods pushes or pulls a U-shaped plate to slide inside the circular box. At this time, three arc-shaped plates move closer to each other, clamping and fixing the exhaust pipe. The rubber pad is compressed and deformed, thus achieving a quick clamping and fixing effect on the exhaust pipe. The operator can adjust the fixing according to the exhaust pipe's specifications. The circular box and U-shaped plate slide together to block flying debris, preventing direct contact between debris and the internal structure, thus avoiding damage to components. This greatly improves the flexibility of the device and extends its service life. The extension and return properties of the spring allow the teeth and the outer edge of the toothed ring to mesh, achieving a quick adjustment and fixing effect on the rotating pipe. This effectively prevents the exhaust pipe from shifting due to external force collisions.

[0016] 1. The operator rotates a drive rod to rotate the circular plate in both directions. This rotation causes multiple sets of movable rods to rotate, pushing or pulling the U-shaped plate inside the circular box. When the movable rod pushes the U-shaped plate outwards, the three arc-shaped plates expand and move towards each other. When the movable rod pulls the U-shaped plate inwards, the three arc-shaped plates move closer together, clamping and fixing the exhaust pipe to the outside. The rubber pads are compressed and deformed, achieving a quick clamping and fixing effect on the exhaust pipe. The operator can adjust the fixing according to the exhaust pipe's specifications. The circular box and the U-shaped plate sliding together effectively block flying debris from the front, preventing debris from colliding with the interior. Direct contact with the structure prevents damage to components, greatly improving the flexibility of the device during use and extending its service life. The movement of the arc plate drives the limiting rod to slide inside the limiting plate. At this time, the stop block limits the limiting rod, thereby achieving the effect of supporting and guiding the movement of the arc plate, further improving the stability of the arc plate during movement. By rotating the rotating tube inside the support plate, the angle of the exhaust pipe after fixing can be quickly adjusted. By rotating the threaded seat on the outside of the threaded teeth, one side of the threaded seat is pressed and fixed between the rotating tube, thereby achieving the effect of quickly fixing the limiting drive rod and improving the stability of the exhaust pipe clamping process.

[0017] 2. After the exhaust pipe angle is adjusted, the operator pulls the slide bar and slides it inside the limit box. The movement of the slide bar causes the slide plate to move, which in turn compresses the two sets of retraction rods and retraction springs. The retraction springs are then compressed and contracted. When the operator releases the slide bar, the retraction springs extend and return to their original position, allowing the teeth to mesh with the outer edge of the toothed ring. This enables quick adjustment and fixation of the rotating pipe, effectively preventing the exhaust pipe from shifting due to external forces. This further improves the stability of the exhaust pipe during processing. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-5The present invention provides a technical solution: a quick positioning and clamping device for an automobile exhaust pipe, including a support frame 1, a support plate 101 slidably connected to the upper interior of the support frame 1, and a base 102 fixedly connected to the bottom of the support frame 1; a clamping mechanism 2 is provided on one side of the support plate 101, and a limit component 3 is provided inside the clamping mechanism 2.

[0026] The clamping mechanism 2 includes a circular box 201, which is located on the top side of the support plate 101. A drive rod 202 is rotatably connected to one side of the circular box 201, and a circular plate 203 is fixedly connected to one end of the drive rod 202. Movable rods 204 are rotatably connected to the side of the circular plate 203 away from the center. U-shaped plates 205 are slidably connected inside the circular box 201, and the end of the movable rod 204 away from the circular plate 203 is rotatably connected to the U-shaped plate 205. Limiting plates 206 are fixedly connected to the side of the circular box 201 away from the support plate 101. One end of U-shaped plate 205 passes through the limiting plate 206 and is slidably connected to the limiting plate 206. Moreover, one end of U-shaped plate 205 is fixedly connected to arc plate 207, and the inner side of arc plate 207 is inlaid with rubber pad 208, so as to achieve the effect of quickly clamping and fixing the exhaust pipe. The operator can adjust and fix it according to the specifications of the exhaust pipe. By using the circular box 201 and U-shaped plate 205 to slide in contact, the debris flying from the front can be blocked, avoiding direct contact between debris and internal structure, which would cause damage to parts. This greatly improves the flexibility of the device during use and extends the service life of the equipment.

[0027] A limiting rod 209 is fixedly connected to one side of the arc plate 207, and one end of the limiting rod 209 passes through the limiting plate 206 and is slidably connected to the limiting plate 206. A stop block 210 is fixedly connected to the end of the limiting rod 209 away from the arc plate 207. The movement of the arc plate 207 drives the limiting rod 209 to slide inside the limiting plate 206. At this time, the stop block 210 limits the limiting rod 209, thereby achieving the effect of supporting and guiding the arc plate 207 during movement, and further improving the stability of the arc plate 207 during movement.

[0028] A rotating tube 211 is fixedly connected to the side of the round box 201 away from the U-shaped plate 205. One end of the rotating tube 211 passes through the support plate 101 and is rotatably connected to the support plate 101. Threaded teeth 212 are welded to the outer side of the drive rod 202 away from the round box 201, and a threaded seat 213 is threadedly connected to the outer thread of the threaded teeth 212. This enables the quick fixing and limiting of the drive rod 202, improving stability during the exhaust pipe clamping process. A rotating handle 214 is fixedly connected to the end of the drive rod 202 away from the support plate 101. By rotating the handle 214... The design of 14 facilitates the operation of the drive rod 202 by the operator. A fixing knob 215 is threadedly connected to one side of the support frame 1, and threaded grooves 216 are provided on one side of the support plate 101. The outside of the fixing knob 215 is threadedly connected to the inside of the threaded groove 216. By utilizing the cooperation between the fixing knob 215, the support frame 1 and the threaded groove 216, the height of the fixed support plate 101 can be quickly adjusted, which makes it easier for the operator to adjust the height according to the needs of exhaust pipe processing and improves the flexibility of equipment use.

[0029] The limiting component 3 includes a limiting box 301 fixedly installed on one side of the top of the support plate 101. A toothed ring 302 is welded to the outside of the rotating pipe 211. A sliding rod 303 is slidably connected inside the limiting box 301. A sliding plate 304 is fixedly connected to the bottom of the sliding rod 303. The outside of the sliding plate 304 is slidably connected to the inside of the limiting box 301. Teeth 305 are welded to the bottom of the sliding plate 304. The teeth 305 are meshed with the outside of the toothed ring 302. A retraction rod 306 is symmetrically fixedly connected between the inside of the limiting box 301 and the sliding plate 304. A retraction spring 307 is sleeved on the outside of the retraction rod 306. This enables the rapid adjustment and fixing of the rotating pipe 211, effectively preventing the exhaust pipe from shifting due to external force collisions, thereby further improving the stability of the exhaust pipe during processing.

[0030] Working principle: Before using this type of quick positioning and clamping device for automotive exhaust pipes, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5As shown, the operator first places the equipment in a suitable area, then places one end of the exhaust pipe against the surface of the circular box 201. At this time, the three arc-shaped plates 207 correspond to the outside of the exhaust pipe. By rotating the drive rod 202, the operator drives the circular plate 203 to rotate in both directions. The rotation of the circular plate 203 drives the rotation of multiple sets of movable rods 204. The rotation of the movable rods 204 pushes or pulls the U-shaped plate 205 to slide inside the circular box 201. When the movable rod 204 pushes the U-shaped plate 205 to move outward, the three arc-shaped plates 207 unfold and move relative to each other. When the movable rod 204 pulls the U-shaped plate... When 205 moves inward, the three arc-shaped plates 207 move closer to each other, clamping and fixing the exterior of the exhaust pipe. At this time, the rubber pad 208 is compressed and deformed, achieving a quick clamping and fixing effect on the exhaust pipe. Furthermore, operators can adjust the fixing according to the exhaust pipe's specifications. The circular box 201 and the U-shaped plate 205 slide against each other, effectively blocking flying debris from the front and preventing direct contact between debris and internal structures, thus avoiding damage to components. This greatly improves the flexibility of the device during use and extends its service life. The movement of the arc-shaped plate 207 causes the limiting rod 209 to slide inside the limiting plate 206. At this time, the stop block 210 limits the limiting rod 209, thereby achieving the effect of supporting and guiding the movement of the arc-shaped plate 207, further improving the stability of the arc-shaped plate 207 during movement. By rotating the rotating tube 211 inside the support plate 101, the angle of the exhaust pipe after fixing can be quickly adjusted. By rotating the threaded seat 213 on the external thread of the threaded teeth 212, one side of the threaded seat 213 is connected to the rotating tube 216. The clamping mechanism between the support plate 101 and the support frame 1 enables quick fixation of the limit drive rod 202, improving stability during exhaust pipe clamping. The design of the rotating handle 214 facilitates operation of the drive rod 202 by the operator. By sliding the support plate 101 inside the support frame 1 and utilizing the cooperation between the fixing knob 215, the support frame 1, and the threaded groove 216, the height of the fixed support plate 101 can be quickly adjusted, allowing the operator to adjust the height according to the exhaust pipe processing needs and improving the flexibility of equipment use.

[0031] After the exhaust pipe angle is adjusted, the operator pulls the slide bar 303 to slide inside the limit box 301. The movement of the slide bar 303 drives the movement of the slide plate 304. The movement of the slide plate 304 compresses the two sets of retraction rods 306 and the retraction spring 307. At this time, the retraction spring 307 is compressed and contracted. Then, the operator releases the slide bar 303, and the retraction spring 307 extends and returns to its original position, so that the teeth 305 and the toothed ring 302 can mesh and connect. This achieves the effect of quickly adjusting and fixing the rotating pipe 211, and effectively avoids the exhaust pipe from shifting due to external force collisions, thereby further improving the stability of the exhaust pipe during processing.
