Description

Technical Field

[0001] This invention relates to the field of wheel hub blank transfer technology, and in particular to a vehicle wheel hub blank transport and transfer device. Background Technology

[0002] A car wheel hub is a metal component mounted on a wheel. It is an important part of connecting the car tire and the car suspension system. Wheel hubs are usually made of aluminum alloy or steel. During the manufacturing process, cylindrical aluminum or steel billets need to be transported to a machine tool for deep machining to form a complete wheel hub.

[0003] Based on the above, existing automotive wheel hub blanks have the following shortcomings during transportation and handling: Freshly cast aluminum or steel billets are usually laid flat on the ground to dissipate heat. When transferring the aluminum or steel billets to the machine tool, the wheel hub billets are usually moved to the transfer cart manually. Due to the large weight of the wheel hub billets, the labor intensity of manual handling is very high, and the wheel hub billets may also slide or roll during handling, resulting in low handling efficiency. Summary of the Invention

[0004] This disclosure relates to a vehicle wheel hub blank transportation and transfer device. It comprises two longitudinally arranged conveyor supports at the rear ends of the left and right sides of a transfer frame, with rotatable side deflector frames connected in connecting slots at the front and rear ends of the conveyor supports. Sliding guides are symmetrically connected to the side walls of the opposing conveyor supports. These sliding guides and side deflector frames, in conjunction with self-driving rollers, guide the conveyor belt, allowing the wheel hub blanks to be picked up from the ground and transported forward via two opposing conveyor belts at the rear bottom of the transfer frame. This reduces manual operation steps, thereby alleviating labor intensity and improving the efficiency of wheel hub blank transfer and transportation. The operation at the top of the transfer frame is for transporting the wheel hub blanks backward for storage. The sliding guides and side deflector frames, under the action of support springs and arc springs, can extend, retract, and deflect to accommodate wheel hub blanks of different specifications, thus improving the adaptability of the transportation and transfer device. Furthermore, the self-driving rollers and conveyor belts, under the action of magnetic guide blocks, enhance the stability of transporting the wheel hub blanks.

Guide sliding holes are opened at equal intervals in the middle of the upper and lower sides of the conveying bracket. An isolation guard plate is fixedly connected to the middle of the rear side of the transfer frame and the middle of the side baffle.

[0007] Furthermore, the left and right side walls of the transfer frame are fixedly connected to lateral fixing plates, and a lateral guide groove is provided in the middle of the lateral fixing plate. A lifting electric cylinder is fixedly installed on the outer side wall of the lateral fixing plate at the top of the lateral guide groove. The bottom telescopic end of the lifting electric cylinder is connected to the lifting cross plate. A sliding guide groove is provided in the middle of the front side wall of the transfer frame.

[0008] Furthermore, the side deflection frame is rectangular and ring-shaped, and a guide hole is provided in the middle of the upper and lower crossbars of the side deflection frame. The guide hole is slidably connected to the upper and lower curved guide rods at the front and rear ends of the transport bracket of the transfer vehicle frame.

[0009] Furthermore, the sliding guide is U-shaped, and a blocking card is fixedly installed in the middle of the sliding guide. The sliding guide on one side of the blocking card is slidably connected to the guide hole opened in the conveying bracket of the transfer vehicle frame. A support spring is sleeved on the sliding guide between the guide hole and the blocking card. A bottom cone seat is provided at the bottom of the curved end of the sliding guide, and the bottom cone seat is rotatably connected to the middle of the bottom of the self-driving roller.

[0010] Furthermore, a magnetic groove is provided in the middle of the outer side wall of the self-driving roller, and a magnetic guide block in the middle of the inner side wall of the conveyor belt is attracted and connected in the magnetic groove. The outer side wall of the conveyor belt is covered with a layer of felt.

[0011] Furthermore, an outer support frame is fixedly connected to the outer side wall of the rear end of the transport bracket of the transfer vehicle frame and the bottom of the outer side wall of the lateral fixing plate. A luffing electric cylinder is fixedly installed on the top of the outer support frame, and a traveling wheel is connected to the bottom telescopic end of the luffing electric cylinder through the outer support frame.

[0012] Furthermore, the lifting cross plate has an inclined guide plate at the middle of its rear side wall, and a side sliding guide block is fixedly connected at the middle of the left and right side walls of the lifting cross plate. The side sliding guide block is slidably connected in the side guide groove opened in the side direction fixing plate at the front end of the transfer frame. The top of the side sliding guide block is connected to the telescopic end of the lifting electric cylinder fixedly installed on the side direction fixing plate. The reinforcing slider at the middle of the front outer wall of the lifting cross plate is slidably connected in the sliding guide groove at the front end of the transfer frame. The telescopic end of the push-pull electric cylinder fixedly connected at the middle of the front reinforcing slider of the lifting cross plate is fixedly connected to a push-pull plate, which is slidably connected to the rear side wall of the front end of the lifting cross plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By longitudinally arranging two conveyor supports at the rear ends of the left and right sides of the transfer frame, and rotating side deflector frames in the connecting slots at the front and rear ends of the conveyor supports, and symmetrically connecting sliding guide frames on the side walls of the left and right opposite conveyor supports, the sliding guide frames and side deflector frames, in conjunction with the self-driving rollers, guide the conveyor belts. This allows the two opposite conveyor belts at the bottom rear of the transfer frame to pick up and transport wheel hub blanks from the ground, reducing manual operation steps, thus alleviating the labor intensity of manual handling and improving the efficiency of wheel hub blank transfer. This operation at the top of the transfer frame is for transporting wheel hub blanks backward for storage. Under the action of support springs and arc springs, the sliding guide frames and side deflector frames can be extended, retracted, and deflected to adapt to wheel hub blanks of different specifications, thereby improving the adaptability of the transport and transfer device. Furthermore, the self-driving rollers and conveyor belts, under the action of magnetic guide blocks, improve the stability of transporting wheel hub blanks.

[0014] 2. By adjusting the height of the bottom traveling wheels using the luffing electric cylinder, the ground clearance of the transfer frame can be changed in four different directions. When the extension end of the luffing electric cylinder at the rear of the transfer frame retracts, the rear height of the transfer frame will decrease to improve the ease of picking up the wheel hub blanks. By extending the extension ends of the four luffing electric cylinders, the gap between the transfer frame and the ground can be increased, thereby improving the passability of the transport and transfer device to facilitate transfer between different workstations.

[0015] 3. By using the lifting electric cylinders fixedly installed on the top of the left and right front side fixing plates of the transfer frame, the lifting electric cylinders can control the lifting cross plate through the bottom telescopic end, so as to lift the wheel hub blanks on the lifting cross plate and thus lift the bottom of the transfer frame to a higher position. Then, by using the push-pull plate connected to the rear telescopic end of the push-pull electric cylinder, the wheel hub blanks on the lifting cross plate are pushed to the top conveyor belt of the transfer frame, and the wheel hub blanks are transported backward for storage, thereby increasing the load capacity of wheel hub blank transportation and transfer.

Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0028] Example 1: Please refer to Figures 1 to 8 As shown: This invention provides a vehicle wheel hub blank transportation and transfer device, including a transfer frame 1; a side deflector 2 is hinged to the middle and rear end of the transfer frame 1, and a sliding guide 4 is slidably connected at equal distances to the rear side of the middle of the transfer frame 1. A self-driving roller 5 is rotatably connected to the side deflector 2 and the sliding guide 4, and a conveyor belt 7 is connected to the outside of the self-driving roller 5. A variable amplitude electric cylinder 8 is fixedly installed at both ends of the left and right outer side walls of the transfer frame 1, and a lifting cross plate 10 is slidably connected to the inner bottom plate of the front end of the transfer frame 1. A push-pull electric cylinder 11 is fixedly installed at the middle of the front outer side wall of the lifting cross plate 10.

[0029] The transfer frame 1 has two longitudinally arranged conveyor brackets 101 on both the left and right rear ends. A side baffle 105 is fixedly installed in the middle of the opposite side walls of the two upper and lower conveyor brackets 101. A connecting slot 108 is opened in the conveyor brackets 101 on both the front and rear sides of the side baffle 105. A side deflector 2 is rotatably connected in the connecting slot 108. An arc-shaped curved guide rod 102 is fixedly installed on both the upper and lower ends of the conveyor bracket 101. An arc-shaped spring 3 is sleeved on the curved guide rod 102. Guide sliding holes 104 are opened at equal intervals in the middle of the upper and lower sides of the conveyor bracket 101. An isolation guard plate 109 is fixedly connected to the middle of the rear side of the transfer frame 1 and the middle of the side baffle 105.

[0030] The side deflection frame 2 is rectangular ring-shaped. A guide hole 201 is provided in the middle of the upper and lower crossbars of the side deflection frame 2. The guide hole 201 is slidably connected to the upper and lower curved guide rods 102 at the front and rear ends of the conveying bracket 101 of the transfer vehicle frame 1.

[0031] The sliding guide 4 is U-shaped, and a blocking card 401 is fixedly installed in the middle of the sliding guide 4. The sliding guide 4 on one side of the blocking card 401 is slidably connected to the guide slide hole 104 opened in the conveying bracket 101 of the transfer frame 1. A support spring 6 is sleeved on the sliding guide 4 between the guide slide hole 104 and the blocking card 401. A bottom cone seat 402 is provided at the bottom of the bent end of the sliding guide 4. The bottom cone seat 402 is rotatably connected to the middle of the bottom of the self-driving roller 5.

[0032] The self-driving roller 5 has a magnetic groove 501 in the middle of its outer side wall, and the magnetic guide block 701 in the middle of the inner side wall of the conveyor belt 7 is attracted and connected in the magnetic groove 501. The outer side wall of the conveyor belt 7 is covered with a layer of felt.

[0033] By adopting the above technical solution, two conveying brackets 101 are longitudinally arranged at the rear ends of the left and right sides of the transfer frame 1, and the side deflection brackets 2 are rotatably connected in the connecting grooves 108 at the front and rear ends of the conveying brackets 101. Sliding guides 4 are symmetrically connected on the side walls of the left and right opposite conveying brackets 101. Thus, the sliding guides 4 and the side deflection brackets 2 cooperate with the self-driving rollers 5 to guide the conveyor belts 7, so that the wheel hub blanks on the ground can be picked up and transported forward by the two opposite conveyor belts 7 at the bottom rear side of the transfer frame 1. This reduces the number of manual operation steps, thereby reducing the labor intensity of manual handling and improving the transfer efficiency of wheel hub blanks. This operation at the top of the transfer frame 1 is to transport the wheel hub blanks backward for storage. Under the action of the support springs 6 and the arc springs 3, the sliding guides 4 and the side deflection brackets 2 can be extended, retracted and deflected to adapt to wheel hub blanks of different specifications, thereby improving the adaptability of the transport and transfer device. Furthermore, under the action of the magnetic guide block 701, the self-driving rollers 5 and the conveyor belts 7 improve the stability of transporting wheel hub blanks.

[0034] Example 2: Based on the automobile wheel hub blank transportation and transfer device provided in Example 1, this device arranges two conveying brackets 101 longitudinally on the left and right rear ends of the transfer frame 1, and rotates a side deflector 2 in the connecting grooves 108 at the front and rear ends of the conveying brackets 101. Sliding guides 4 are symmetrically connected on the side walls of the left and right opposite conveying brackets 101, so that the sliding guides 4 and the side deflector 2 cooperate with the self-driving rollers 5 to guide the conveyor belts 7, so that the wheel hub blanks on the ground can be picked up and transported forward by the two opposite conveyor belts 7 at the rear bottom of the transfer frame 1, reducing the number of manual operation steps, thereby reducing the labor intensity of manual handling and improving the transfer and transportation efficiency of wheel hub blanks. The automobile wheel hub blank transportation and transfer device also includes: an outer support frame 103 is fixedly connected to the rear outer side wall of the conveying brackets 101 of the transfer frame 1 and the bottom of the outer side wall of the side fixing plate 106. A variable amplitude electric cylinder 8 is fixedly installed on the top of the outer support frame 103, and the bottom telescopic end of the variable amplitude electric cylinder 8 passes through the outer support frame 103 and is connected to a traveling wheel 801.

[0035] By adopting the above technical solution, the height of the bottom traveling wheels 801 can be adjusted by using the luffing electric cylinder 8, thereby changing the ground clearance of the transfer frame 1 in four different directions. When the extension end of the luffing electric cylinder 8 on the rear side of the transfer frame 1 is retracted, the rear height of the transfer frame 1 will be reduced to improve the ease of picking up the wheel hub blank. By extending the extension ends of the four luffing electric cylinders 8, the gap between the transfer frame 1 and the ground can be increased, thereby improving the passability of the transport and transfer device so as to facilitate transfer between different workstations.

[0036] Example 3: Based on the automobile wheel hub blank transportation and transfer device provided in Example 1, this device uses two conveying brackets 101 arranged longitudinally at the rear ends of the left and right sides of the transfer frame 1. Side deflecting brackets 2 are rotatably connected in the connecting grooves 108 at the front and rear ends of the conveying brackets 101. Sliding guides 4 are symmetrically connected to the side walls of the left and right opposite conveying brackets 101. Thus, the sliding guides 4 and the side deflecting brackets 2, in cooperation with the self-driving rollers 5, guide the conveyor belts 7, so that the wheel hub blanks on the ground are picked up and transported forward by the two opposite conveyor belts 7 at the rear bottom of the transfer frame 1, reducing [the burden on the vehicle]. The manual operation steps reduce the labor intensity of manual handling and improve the efficiency of wheel hub blank transfer. The wheel hub blank transfer device also includes: a lateral fixing plate 106 fixedly connected to the front end of the left and right side walls of the transfer frame 1; a lateral guide groove 10601 is opened in the middle of the lateral fixing plate 106; a lifting electric cylinder 9 is fixedly installed on the outer side wall of the lateral fixing plate 106 at the top of the lateral guide groove 10601; the bottom telescopic end of the lifting electric cylinder 9 is connected to the lifting cross plate 10; and a sliding guide groove 107 is opened in the middle of the front side wall of the transfer frame 1.

[0037] The lifting horizontal plate 10 has an inclined guide plate 1001 at the middle of the rear side wall, and a side sliding guide block 1002 is fixedly connected at the middle of the left and right side walls of the lifting horizontal plate 10. The side sliding guide block 1002 is slidably connected in the side guide groove 10601 opened in the side direction fixing plate 106 at the front end of the transfer frame 1. The top of the side sliding guide block 1002 is connected to the telescopic end of the lifting electric cylinder 9 fixedly installed on the side direction fixing plate 106. The reinforcing slider 1003 at the middle of the front outer wall of the lifting horizontal plate 10 is slidably connected in the sliding guide groove 107 at the front end of the transfer frame 1. The push-pull electric cylinder 11 fixedly connected at the middle of the front reinforcing slider 1003 of the lifting horizontal plate 10 has a push-pull plate 1101 fixedly connected to the telescopic end of the rear side of the front side of the lifting horizontal plate 10. The push-pull plate 1101 is slidably connected to the rear side wall at the front end of the lifting horizontal plate 10.

[0038] Using the above technical solution, the lifting electric cylinder 9, which is fixedly installed on the top of the left and right front side fixing plate 106 of the transfer frame 1, can control the lifting cross plate 10 through the bottom telescopic end of the lifting electric cylinder 9, so as to lift the wheel hub blank on the lifting cross plate 10 to the bottom of the transfer frame 1 to a higher position. Then, the wheel hub blank on the lifting cross plate 1101 connected to the rear telescopic end of the push-pull electric cylinder 11 pushes the wheel hub blank on the lifting cross plate 10 to the top conveyor belt 7 of the transfer frame 1, and transports the wheel hub blank backward for storage, thereby increasing the load capacity of wheel hub blank transportation and transfer.

[0039] The specific usage and function of this embodiment: In this invention, two conveying brackets 101 are longitudinally arranged at the rear ends of the left and right sides of the transfer frame 1, and a side deflection bracket 2 is rotatably connected in the connecting slots 108 at the front and rear ends of the conveying bracket 101. Sliding guides 4 are symmetrically connected to the side walls of the left and right opposite conveying brackets 101. This allows the sliding guides 4 and the side deflection brackets 2, in conjunction with the self-driving roller 5, to guide the conveyor belt 7, so that the two opposite conveyor belts 7 at the rear bottom of the transfer frame 1 can pick up the wheel hub blanks on the ground and transport them forward. This reduces the steps of manual operation, thereby reducing the labor intensity of manual handling and improving the efficiency of wheel hub blank transfer. This operation at the top of the transfer frame 1 is to transport the wheel hub blanks backward for storage. Under the action of the support spring 6 and the arc spring 3, the sliding guides 4 and the side deflection brackets 2 can extend, retract, and deflect to adapt to wheel hub blanks of different specifications, thereby improving the adaptability of the transport and transfer device. Furthermore, under the action of the magnetic guide block 701, the self-driving roller 5 and the conveyor belt 7 are lifted... To ensure the stability of transporting wheel hub blanks, the height of the bottom traveling wheels 801 can be adjusted by using the luffing electric cylinder 8, thus changing the ground clearance of the transfer frame 1 in four different directions. When the telescopic end of the luffing electric cylinder 8 at the rear of the transfer frame 1 retracts, the rear height of the transfer frame 1 decreases, improving the ease of picking up the wheel hub blanks. By extending the telescopic ends of the four luffing electric cylinders 8, the clearance between the transfer frame 1 and the ground can be increased, thereby improving the passability of the transport and transfer device to facilitate transfer between different workstations. The lifting electric cylinder 9 is fixedly installed on the top of the left and right front side fixing plate 106 of the frame 1. The lifting electric cylinder 9 can control the lifting cross plate 10 through the bottom telescopic end, so as to transfer the wheel hub blank on the lifting cross plate 10 and lift the bottom of the frame 1 to a higher position. Then, the wheel hub blank on the lifting cross plate 1101 connected to the rear telescopic end of the push-pull electric cylinder 11 pushes the wheel hub blank on the lifting cross plate 10 to the top conveyor belt 7 of the transfer frame 1, and transports the wheel hub blank backward for storage, thereby increasing the load capacity of wheel hub blank transportation and transfer.
