Description

Technical Field

[0001] This utility model relates to the technical field of conveying devices, and in particular to a cage-type hub abrasive conveying device, specifically, a hub grinding machine. Background Technology

[0002] High-end aluminum alloy wheels typically undergo a series of processes during manufacturing, including forging, sandblasting and grinding, machine rough grinding, machine fine grinding, soaking and cleaning, air gun drying, and subsequent testing. The fine grinding process utilizes a wheel grinding machine with high-strength composite grinding stones and an appropriate amount of environmentally friendly water-based polishing fluid. This automated process polishes the entire circumference of the aluminum wheel. Zirconium silicate grinding stones with a spherical diameter of approximately 1.8-2mm are usually selected. As the grinding stones are used over time, they will experience varying degrees of wear. Adding more grinding stones as needed is necessary, and periodic screening is required to replace any worn stones smaller than 0.3mm. When screening is required, 4-5 tons of abrasive material must be removed from the grinding machine's hopper, taking care not to damage the original surface finish of the transported abrasive material.

[0003] There are various methods for handling abrasive materials, all of which affect the surface of the abrasive material to varying degrees. For example, spiral tube suction machines can transport materials, but the high-speed rotation of the screw can damage the surface smoothness of the abrasive material to varying degrees. Ordinary chain and sprocket conveyors have internal transmission structures that are difficult to seal effectively, and abrasive material can easily get stuck in the chain, making it impossible to operate for extended periods. Similarly, synchronous belt external baffle conveyors also have internal transmission structures that are difficult to seal effectively, and abrasive material can easily get stuck in the synchronous pulley, making it impossible to operate for extended periods.

[0004] Therefore, this utility model provides a new technical solution to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cage-type wheel hub abrasive conveying device that will not damage the original surface finish of the abrasive during the transfer process, thereby improving the wheel hub grinding quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cage wheel type hub abrasive conveying device includes a frame, two cage wheels, a chain and a conveying box. The cage wheels are rotatably mounted at both ends of the frame, and one of the cage wheels is driven to rotate by a motor. The cage wheel includes two fixing members and several connecting rods. The connecting rods are fixedly installed between the two fixing members and are arranged in a circular array around the rotation axis of the cage wheel; the chain passes around the two cage wheels. The chain includes several drive links and load links, which are evenly distributed along the length of the chain. Each drive link is integrally connected with a protrusion, which can mesh with the connecting rod of the cage wheel for transmission. The conveyor box for conveying abrasive material is installed on the outer periphery of the chain link.

[0007] The present invention is further configured such that the frame includes a conveying start end and a conveying end end, and the two cage wheels are a main cage wheel and an auxiliary cage wheel, respectively. The main cage wheel is fixedly installed at the conveying end of the frame through a movable bearing seat, and the auxiliary cage wheel is rotatably installed at the conveying start end of the frame through an auxiliary wheel drive shaft.

[0008] The present invention is further configured such that the main cage wheel is rotatably mounted on the movable bearing seat via the main wheel drive shaft and is driven to rotate by a motor, and the main wheel drive shaft can drive the main cage wheel to extend and retract relative to the movable bearing seat along the frame direction for adjustment.

[0009] The present invention is further configured such that the movable bearing seat is fixedly installed on both sides of the frame via connecting plates, and the connecting plates on both sides are fixedly installed with sliding grooves. Limiting plates are embedded in the sliding grooves. One end of the limiting plate is fixedly connected to the main wheel drive shaft, and the other end is fixedly connected to a screw. An adjusting nut is threadedly connected to the outer circumference of the screw. By rotating the adjusting nut, the main cage wheel can be adjusted to extend and retract along the frame direction.

[0010] The present invention is further configured such that the transmission links and the load links are distributed at intervals, and a load link is provided between two adjacent transmission links.

[0011] The present invention is further configured such that the transmission chain link is integrally connected with a protrusion in the direction of the inner circumference of the chain, the protrusion being able to be embedded between two connecting rods and meshing with the connecting rods for transmission; the distance between adjacent connecting rods is greater than twice the particle size of the abrasive.

[0012] The present invention is further configured such that a mounting plate is integrally connected to the load-carrying chain link in the direction of the outer periphery of the chain, and the mounting plate has mounting holes for fixing and mounting the conveyor box.

[0013] The present invention is further configured such that a limiting crossbar is fixedly installed on the outer periphery of the frame and between the beginning and end of the conveying process. The limiting crossbar has a semi-enclosed structure and is positioned between the two sides of the conveying box.

[0014] The present invention is further configured to include a support frame, which is rotatably mounted on the conveying end of the frame via a secondary wheel drive shaft, and the support frame can be rotated and adjusted along the axial direction of the secondary wheel drive shaft.

[0015] A wheel hub grinding machine includes a cage wheel type wheel hub grinding material conveying device as described in any of the above claims, and further includes a screening device and a material hopper.

The connecting rods are fixedly installed between the two fixed parts and are distributed in a circular array around the rotation axis of the cage wheel. The distance between adjacent connecting rods is more than twice the particle size of the abrasive material, which allows the abrasive material to pass freely through the cage wheel and avoids jamming between the abrasive material and the connecting rods, thus preventing the normal operation of the equipment.

[0017] The chain includes a load link and a drive link. The drive link has a protrusion integrally connected to the inner circumference of the chain. The protrusion can be inserted between two connecting rods and engage with the connecting rods for transmission.

During the transmission between the chain and the cage wheel, it can prevent abrasive material from getting stuck in the chain gap, which would affect the normal operation of the equipment. Moreover, it will not damage the surface finish of the abrasive material during the conveying process, thus improving the grinding quality of the wheel hub. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] This embodiment discloses a cage-type hub abrasive conveying device, referring to... Figures 1-7As shown, the main components include a frame 1, two cage wheels 2, a chain 3, and a conveyor box 4. The frame 1 includes a conveying start end 11 and a conveying end end 12. The two cage wheels 2 are a main cage wheel 21 and an auxiliary cage wheel 22. The main cage wheel 21 is fixedly installed at the conveying end end 12 of the frame 1 via a movable bearing seat 14 and is driven to rotate by a motor 23. The auxiliary cage wheel is rotatably installed at the conveying start end 11 of the frame 1 via an auxiliary wheel drive shaft 221. The cage wheel 2 is mainly composed of two fixing parts 24 and several connecting rods 25. The connecting rods 25 are fixedly installed between the two fixing parts 24 and are arranged in a circular array around the rotation axis of the cage wheel 2. The distance between two adjacent connecting rods 25 is greater than twice the particle size of the abrasive, which can effectively and automatically avoid the abrasive from getting stuck. The chain 3 passes around the two cage wheels 2 and transmits motion through the main cage wheel 21. The chain 3 includes several transmission chain links 32 and The chain link 31, including the drive chain link 32 and the load chain link 31, are evenly distributed along the length of the chain 3. The drive chain link 32 and the load chain link 31 are spaced apart, with a load chain link 31 between two adjacent drive chain links 32. The drive chain link 32 has a protrusion 321 integrally connected to the inner circumference of the chain 3. The protrusion 321 can be embedded between two connecting rods 25 and engage with the connecting rods 25 for transmission. The load chain link 31 has a mounting plate 311 integrally connected to the outer circumference of the chain 3. The mounting plate 311 has mounting holes 312 for fixing and installing the conveyor box 4 for conveying abrasive materials. When using this chain 3 to drive the cage wheel 2 and convey abrasive materials through the conveyor box 4, it can avoid the abrasive materials getting stuck in the chain gaps, which would affect the normal operation of the equipment. Moreover, the surface finish of the abrasive materials will not be damaged during the conveying process, thus improving the grinding quality of the wheel hub.

[0028] Reference Figure 2 and Figure 3 As shown, a main cage wheel 21 that can be telescopically adjusted along the direction of the frame 1 is installed at the conveying end 11 of the frame 1 via a movable bearing seat 14. Specifically, the movable bearing seat 14 is fixedly installed on both sides of the frame 1 via a connecting plate 141. A slide groove 142 is fixedly installed on the outer side of the connecting plate 141 along the length direction of the frame 1. A limit plate 143 is embedded in the slide groove 142. The limit plate 143 can slide and adjust along the direction of the slide groove 142. One end of the limit plate 143 is fixedly connected to the drive shaft 211, and the other end is fixedly installed with a screw 144. An adjusting nut 145 is threadedly connected to the outer circumference of the screw 144. The other end of the screw 144 is connected to the connecting plate 141 and locked by the adjusting nut 145. By rotating the adjusting nut 145, the telescopic adjustment of the main cage wheel 21 along the direction of the frame 1 can be realized. This is mainly to adjust the tension of the chain 3, which facilitates the normal operation of the equipment and also facilitates installation and maintenance.

[0029] Reference Figure 7As shown, chain 3 adopts a double-row conveying structure, which helps to form a relatively wide support surface, enhancing its resistance to torsion and overturning, and ensuring the smooth conveying of abrasive materials. Chain 3 passes over two cage pulleys 2, and the fixing parts 24 at both ends of the cage pulleys 2 prevent the double-row chain 3 from derailing during transmission. (Refer to...) Figure 6 As shown, the transmission link 32 on the chain 3 has a protrusion 321 integrally connected to the inner circumference of the chain 3. The protrusion 321 can be embedded between the two connecting rods 25 and can mesh with the connecting rods 25 for transmission. The meshing part of the protrusion 321 on the transmission link 32 and the connecting rod 25 needs to be hardened to increase the hardness of the meshing part and ensure the smoothness and wear resistance of the transmission.

[0030] Reference Figure 2 As shown, a limiting crossbar 13 is fixedly installed on the outer periphery of the frame 1 and between the conveying start end 11 and the conveying end end 12. The limiting crossbar 13 has a semi-enclosed structure and can block both sides of the conveying box 4, ensuring that the conveying box 4 containing abrasive material does not move or tip over during the movement, thereby improving the stability and reliability of the conveying.

[0031] Reference Figure 3 As shown, a support frame 15 is rotatably mounted at the conveying start end 11 of the frame 1, i.e. the mounting end of the auxiliary cage wheel 22. The support frame 15 is rotatably mounted at both ends of the auxiliary cage wheel 22 via the auxiliary wheel drive shaft 221, and can be rotated and adjusted along the axial direction of the auxiliary wheel drive shaft 221, so that the entire transmission device can be placed at a specific angle at the designated position of the wheel hub grinding machine.

[0032] Reference Figure 1 As shown, this embodiment also discloses a wheel hub grinding machine, including the cage wheel type wheel hub abrasive conveying device as described above, as well as a screening device 5 and a material bucket 6 for holding abrasive materials. In the cage wheel type wheel hub abrasive conveying device, the conveying start end 11, which is rotatably mounted with a support frame 15, is placed in the material bucket 6 and supported by the support frame 15. The appropriate position of the conveying device can be determined by rotating and adjusting the support frame 15. The abrasive material is usually zirconium silicate grinding stones with a spherical diameter of about 1.8~2mm. When the grinding stones are used for a certain period of time, they will be worn to varying degrees. The amount should be added appropriately according to the actual situation. It is necessary to screen and replace the abrasive materials with a worn size of less than 0.3mm periodically. Therefore, the screening device 5 is connected to the conveying end 12 through a connecting pipe 51, and the abrasive material is transferred to the screening device 5 for screening by the conveying device.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
