Technical Field

[0001] The utility model relates to the technical field of automobile wheel hub processing, and specifically relates to a fixing device for automobile wheel hub processing. Background Technique

[0002] A wheel hub is a cylindrical metal part that supports the tire inside the tire contour and is centered on the shaft. It is also called a rim, steel rim, wheel, or tire bell. During the processing of an automobile wheel hub, it is necessary to fix the wheel hub to prevent it from shaking.

[0003] The published patent No. CN220389209U discloses a wheel hub fixing device for automobile wheel hub processing. This device controls the movement of a sleeve through a cylinder, and a fixing rod controlled by a telescopic rod to move up and down is arranged inside the sleeve.

However, this device is not convenient for rotating the fixed wheel hub, resulting in the need for the staff to walk around the fixing device when processing the wheel hub, which brings inconvenience to the staff during use.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A fixing device for automobile wheel hub processing, including a workbench, a bottom plate is arranged at the top end of the workbench, a fixing component is arranged at the top end of the bottom plate, and fixing rods are arranged inside the fixing components; An adjusting mechanism is arranged between the workbench and the bottom plate, and an installation component is arranged at the top of the fixing rod;

[0008] Among them, the adjusting mechanism includes a rotating column installed at the bottom end of the bottom plate, the bottom end of the rotating column is rotatably connected to the workbench, a ring box is installed at the top end of the workbench, a gear is installed on the outer side of the rotating column, rotating seats are installed on the inner sides of the ring box, one end of the rotating seat is rotatably connected to a flapping rod, a torsion spring is arranged between the flapping rod and the rotating seat, and baffles are installed on the inner sides of the ring box.

[0013] Preferably, both ends of the connecting rod are slidably connected inside the sliding grooves.

[0014] Preferably, one end of the insertion rod penetrates through the inside of the fixing box and is slidably connected.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: For a fixing device for automobile wheel hub processing, the specific content is as follows: By rotating the bottom plate by the staff, the rotating column rotates on the workbench. At this time, the rotating column drives the rotation of the gear, and the rotation of the gear squeezes the beating rod, thereby causing the beating rod to rotate. Due to the resilience of the torsion spring, the beating rod beats the gear, enabling the staff to feel a clicking sound, thus solving the problem that the traditional fixing component cannot rotate, enabling the staff to flexibly adjust the position and angle of the wheel hub, so as to meet different processing requirements, and avoiding the high cost of using a motor drive in the traditional method, reducing the production cost. And when the fixing component rotates horizontally to a certain angle, a clicking sound will be emitted. This feedback mechanism can timely remind the staff that a certain angle has been rotated, helping them more accurately control the rotation angle and improve the processing accuracy. Through the shrinkage of the first telescopic spring, the insertion rod can be inserted into the insertion hole, thereby achieving the effect of quickly fixing and limiting the fixing component, ensuring that when the fixing component does not need to adjust the angle, the fixing component can be stably maintained at the required position. By inserting the connecting block into the mounting tube, due to the resilience of the second telescopic spring, the convex block is inserted into the groove, thereby achieving the effect of quickly installing and disassembling the mounting rod, facilitating the staff to replace the rubber sleeve subsequently, and avoiding the phenomenon that it is not easy to maintain when the rubber sleeve squeezes and fixes various specifications of wheel hubs with the mounting rod for a long time.

[0016] 1. By rotating the bottom plate by the staff, the rotating column is driven to rotate on the workbench. At this time, the rotating column drives the rotation of the gear, and the rotation of the gear squeezes the beating rod, thereby causing the beating rod to rotate. At this time, the torsion spring contracts. When the teeth on the surface of the gear no longer squeeze the beating rod, the torsion spring quickly resets at this time, so that the beating rod beats the gear, enabling the staff to feel a clicking sound, thus solving the problem that the traditional fixing component cannot rotate, enabling the staff to flexibly adjust the position and angle of the vehicle hub, so as to adapt to different processing requirements. By manually pushing the fixing component to rotate, the high cost of using a motor drive in the traditional method is avoided, the production cost is reduced, the economic benefit is improved, and the use requirements of small workshops are met. And when the fixing component rotates horizontally to a certain angle, a clicking sound will be emitted. This feedback mechanism can remind the staff in real time that a certain angle has been rotated, helping them control the rotation angle more accurately and improving the processing accuracy. After the angle of the fixing component is adjusted, by pulling the U-shaped rod to drive the connecting rod to slide inside the chute, at this time, both ends of the connecting rod slide outside the support rod, so that the first telescopic spring extends. At this time, the inserting rod slides inside the fixing box. By loosening the U-shaped rod, and then through the contractility of the first telescopic spring, the inserting rod can be inserted into the jack, so as to achieve the effect of quickly fixing and limiting the fixing component, ensuring that when the fixing component does not need to adjust the angle, the fixing component can be stably maintained at the required position, bringing convenience to the staff during use;

[0017] 2. By inserting the connecting block into the mounting pipe, at this time, the connecting block squeezes the convex block, so that the convex block drives the slider to slide inside the fixed pipe. At this time, the second telescopic spring contracts. When the connecting block and the mounting pipe are completely inserted, the second telescopic spring quickly resets at this time, so that the convex block is inserted into the groove, so as to achieve the effect of quickly installing and disassembling the mounting rod, facilitating the staff to replace the rubber sleeve later. Avoid the phenomenon that it is not easy to maintain when the rubber sleeve follows the mounting rod to squeeze and fix various specifications of vehicle hubs for a long time, bringing convenience to the staff during use.

Specific implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution: a fixing device for processing automobile wheels, including a workbench 1, a bottom plate 101 is arranged at the top of the workbench 1, and a fixing component 102 is arranged at the top of the bottom plate 101, and fixing rods 103 are arranged inside the fixing components 102; an adjusting mechanism 2 is arranged between the workbench 1 and the bottom plate 101, and a mounting component 3 is arranged at the top of the fixing rod 103;

[0026] Among them, the adjusting mechanism 2 includes a rotating column 201 installed at the bottom end of the bottom plate 101. The bottom end of the rotating column 201 is rotatably connected to the workbench 1. The top end of the workbench 1 is provided with an annular box 202. A gear 203 is installed on the outer side of the rotating column 201. Rotating seats 204 are installed on the inner sides of the annular box 202. One end of the rotating seat 204 is rotatably connected to a flapping rod 205. The flapping rod 205 is meshed with the outer side of the gear 203. A torsion spring 206 is arranged between the flapping rod 205 and the rotating seat 204. Baffles 207 are installed on the inner sides of the annular box 202. Thus, the problem that the traditional fixing component 102 cannot rotate is solved, enabling the staff to flexibly adjust the position and angle of the vehicle hub, so as to adapt to different processing requirements. By manually pushing the fixing component 102 to rotate, the high cost of using a motor drive in the traditional method is avoided, the production cost is reduced, the economic benefit is improved, and the use requirements of small workshops are met. And when the fixing component 102 rotates horizontally to a certain angle, a clicking sound will be emitted. This feedback mechanism can timely remind the staff that a certain angle has been rotated, which helps them more accurately control the rotation angle and improve the processing accuracy;

[0027] A fixing plate 208 is installed at the bottom end of the bottom plate 101. A fixing box 209 is installed inside the fixing plate 208. A U-shaped rod 210 is slidably connected to the inner part of one end of the fixing box 209. A connecting rod 211 is installed at one end of the U-shaped rod 210. Both ends of the connecting rod 211 are slidably connected inside a chute 212. Chutes 212 are symmetrically opened inside the fixing box 209. A support rod 213 is installed inside the chute 212. Both ends of the connecting rod 211 are slidably connected to the outer side of the support rod 213. A first telescopic spring 214 is sleeved on the outer side of the support rod 213. Insertion rods 215 are symmetrically installed on one side of the connecting rod 211. One end of the insertion rod 215 penetrates through the inside of the fixing box 209 and is slidably connected. Sockets 216 are symmetrically opened on the outer sides of the annular box 202. One end of the insertion rod 215 is inserted into the socket 216. Due to the contractility of the first telescopic spring 214, the insertion rod 215 can be inserted into the socket 216, so as to achieve the effect of quickly fixing and limiting the fixing component 102, ensuring that when the fixing component 102 does not need to adjust the angle, the fixing component 102 can be stably maintained at the required position, bringing convenience to the staff during use. An annular plate 217 is installed at the bottom end of the bottom plate 101. Ball bearings 218 are installed inside the bottom end of the annular plate 217. The bottom ends of the ball bearings 218 are in rolling connection with the top of the annular box 202. When the bottom plate 101 rotates following the fixing component 102, at this time, the bottom plate 101 drives the rotation of the annular plate 217, and the rotation of the annular plate 217 drives the rolling connection between multiple groups of ball bearings 218 and the annular box 202, so that the rotation of the fixing component 102 can be more stable, bringing convenience to the staff during use.

[0028] The installation component 3 includes an installation pipe 301 installed inside the top end of the fixed rod 103. A connection block 302 is inserted into the inside of the installation pipe 301. The top end of the connection block 302 is fixedly connected to an installation rod 303. A rubber sleeve 304 is installed on the outer side of the installation rod 303. Fixed pipes 305 are symmetrically installed inside both sides of the installation pipe 301. A slider 306 is slidably connected to the inside of the fixed pipe 305. A convex block 307 is installed at one end of the slider 306. Grooves 308 are formed on the outer sides of the connection block 302. The convex block 307 is inserted between the grooves 308. A second telescopic spring 309 is arranged inside the fixed pipe 305. Due to the reset property of the second telescopic spring 309, the convex block 307 is inserted between the grooves 308, thereby achieving the effect of quickly installing and disassembling the installation rod 303, facilitating the subsequent replacement of the rubber sleeve 304 by the staff, avoiding the phenomenon that it is not easy to maintain when the rubber sleeve 304 presses and fixes hubs of various specifications together with the installation rod 303 for a long time, and bringing convenience to the staff during use.

[0029] Working principle: Before using the fixing device for automobile hub processing, it is necessary to first check the overall condition of the device to ensure that it can work properly. According to Figure 1 - Figure 5As shown in the figure, the staff rotates the bottom plate 101 to drive the rotating column 201 to rotate on the workbench 1. At this time, the rotating column 201 drives the rotation of the gear 203. The rotation of the gear 203 squeezes the flapping rod 205, thereby causing the flapping rod 205 to rotate. At this time, the torsion spring 206 contracts. When the teeth on the surface of the gear 203 no longer squeeze the flapping rod 205, the torsion spring 206 quickly resets, thereby causing the flapping rod 205 to slap the gear 203, enabling the staff to feel a clicking sound, thus solving the problem that the traditional fixing component 102 cannot rotate. This allows the staff to flexibly adjust the position and angle of the wheel hub to adapt to different processing requirements. By manually pushing the fixing component 102 to rotate, the high cost of using a motor drive in the traditional method is avoided, the production cost is reduced, the economic benefit is improved, and the usage requirements of small workshops are met. And when the fixing component 102 rotates horizontally to a certain angle, a clicking sound will be emitted. This feedback mechanism can timely remind the staff that a certain angle has been rotated, helping them more accurately control the rotation angle and improve the processing accuracy. After the angle of the fixing component 102 is adjusted, by pulling the U-shaped rod 210 to drive the connecting rod 211 to slide inside the chute 212. At this time, both ends of the connecting rod 211 slide outside the support rod 213, thereby causing the first telescopic spring 214 to stretch. At this time, the insertion rod 215 slides inside the fixed box 209. By releasing the U-shaped rod 210, and then through the contractility of the first telescopic spring 214, the insertion rod 215 can be inserted into the insertion hole 216, thereby achieving the effect of quickly fixing and limiting the fixing component 102, ensuring that when the fixing component 102 does not need to adjust the angle, the fixing component 102 can be stably maintained at the required position, bringing convenience to the staff during use. When the bottom plate 101 rotates with the fixing component 102, the bottom plate 101 drives the rotation of the annular plate 217 at this time. The rotation of the annular plate 217 drives multiple groups of balls 218 to roll and connect with the annular box 202, thereby enabling the fixing component 102 to rotate more stably, bringing convenience to the staff during use;

[0030] By inserting the connecting block 302 into the mounting tube 301, the connecting block 302 squeezes the convex block 307 at this time, thereby causing the convex block 307 to drive the slider 306 to slide inside the fixed tube 305. At this time, the second telescopic spring 309 contracts. When the connecting block 302 is fully inserted into the mounting tube 301, the second telescopic spring 309 quickly resets, thereby causing the convex block 307 to be inserted into the groove 308, thus achieving the effect of quickly installing and disassembling the mounting rod 303, facilitating the staff to replace the rubber sleeve 304 subsequently. This avoids the phenomenon that it is not easy to maintain when the rubber sleeve 304 follows the mounting rod 303 to squeeze and fix various specifications of wheel hubs for a long time, bringing convenience to the staff during use.

[0031] The hub fixing device for automobile hub processing disclosed in the prior art with the publication number CN220389209U uses a bottom plate 101 and a fixing component 102, and the device used therein will not be elaborated here.

[0032] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
