Description

Technical Field

[0001] The utility model relates to the technical field of hub processing, and particularly relates to a device for removing the edge gate of a hub. Background Art

[0002] At present, most hub manufacturing plants adopt the form of central casting in low-pressure casting. Due to the insufficient uniformity of melt flow in the single-gate design, the tissue properties of the hub are greatly affected. At the same time, in order to ensure the completion of the hub forming in single-gate casting, generally a very high temperature is required, which is prone to defects such as sticking to the mold and local deformation. At the same time, the too-high temperature will also exacerbate the damage of the mold.

[0003] While adopting the multi-gate process can greatly solve the above problems, but the multi-gates are generally arranged at the edge of the hub. At present, there is still a lack of special equipment for removal, making it difficult to improve the processing efficiency.

[0004] Therefore, in view of the deficiencies of the existing technology, it is necessary to design a device for removing the edge gate of a hub to solve the above problems.

[0005] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the present utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above content is well-known to those skilled in the art just because these contents are described in the background art of the present utility model.

[0014] Preferred technical solution: The clamping mechanism is composed of a number of clamping jaws surrounding each other.

[0015] Preferred technical solution: The lifting mechanism includes a support plate for fixing the second rotating mechanism. A guide rod is slidably connected to the support plate. The guide rod is fixed to the bottom of the processing table. A driving motor is also provided on the processing table. The output end of the driving motor is connected to a transmission lead screw.

[0032] As Figure 1 shown, a device for removing the gate at the edge of a wheel hub disclosed by the present utility model includes a processing table 100. A workpiece conveying mechanism 1 is provided on the processing table 100, and a rough removal station 2 and a fine removal station 3 are provided below the workpiece conveying mechanism 1. The main components of the above-mentioned present utility model will be specifically described below:

[0033] As Figure 1 and Figure 2 shown, the workpiece conveying mechanism 1 includes a loading clamping mechanism 11. The loading clamping mechanism 11 includes a deep groove bearing 11a, and a fourth horizontal movement mechanism 11b is provided above the deep groove bearing 11a; a first rotating mechanism 12 is provided above the fourth horizontal movement mechanism 11b, a first lifting mechanism 13 is connected above the first rotating mechanism 12, detection mechanisms 14 are provided on both sides of the first lifting mechanism 13, and the detection mechanisms 14 include two groups of color difference detection sensors; a first horizontal movement mechanism 15 is provided above the first lifting mechanism 13.

[0034] As Figure 1 、 Figure 3 and Figure 4As shown in the figure, the rough removal station 2 includes a workpiece clamping mechanism 21. On both sides of the workpiece clamping mechanism 21, there are symmetrically arranged pushing heads 22. Below the pushing heads 22, there is a second horizontal movement mechanism 23. The output end of the second horizontal movement mechanism 23 is provided with an oil cylinder 23a. The output end of the oil cylinder 23a is arranged towards the outside of the second horizontal movement mechanism 23, and the output end of the oil cylinder 23a is connected to the pushing head 22.

[0035] As Figure 1 , Figure 3 , Figure 5 and Figure 6 shown, the fine removal station 3 includes a clamping mechanism 31. The clamping mechanism 31 is composed of a number of clamping jaws 31a surrounded. Below the clamping mechanism 31, there is a second rotation mechanism 32. Below the second rotation mechanism 32, there is a lifting mechanism 33. The lifting mechanism 33 includes a support plate 33a for fixing the second rotation mechanism 32. A guide rod 33b is slidably connected to the support plate 33a. The guide rod 33b is fixed to the bottom of the processing table 100. A driving motor 33c is also provided on the processing table 100. The output end of the driving motor 33c is connected to a transmission lead screw 33d. Most of the transmission lead screws 33d are in transmission connection with the support plate 33a; on both sides of the clamping mechanism 31, there are symmetrically arranged milling cutter mechanisms 34. The milling cutter mechanisms 34 are arranged on the processing table 100 through slide rails. On one side of the milling cutter mechanisms 34, there is a nozzle 34a; below the milling cutter mechanisms 34, there is a third horizontal movement mechanism 35.

[0036] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the principle and usage method of a kind of hub edge gate removal device of the present utility model are as follows:

[0037] During use, the feeding and clamping mechanism 11 moves above the hub. The third horizontal movement mechanism 11b moves towards the hub. The hub is clamped through the deep groove bearing 11a. The hub is moved to the rough removal station 2 through the first horizontal movement mechanism 15. The gate of the hub is adjusted to the front of the movement path of the pushing head 22 through the cooperation of the first rotation mechanism 12 and the detection mechanism 14. The hub is placed into the workpiece clamping mechanism 21 through the first lifting mechanism 13. After the hub is fixed by the workpiece clamping mechanism 21, the pushing head 22 moves towards the gate of the hub under the drive of the first horizontal movement mechanism 23. The gate of the hub is broken off by the impact of the pushing head 22. Then, the oil cylinder 23a drives the pushing head 22 to move to both sides and then reset, avoiding collision with the residual part of the gate of the hub during reset. It should be noted that when the gate is broken off by one impact, the rough removal station 2 can also perform a second impact to break and fold the gate of the hub again.

[0038] After the rough machining station 2 processes the hub, the loading and clamping mechanism 11 picks up the rough-machined hub and moves it to the clamping mechanism 31. The clamping mechanism 31 positions and places the hub through the clamping jaws 31a. Then, the second rotating mechanism 32 cooperates with the detection mechanism 14 to adjust the angle of the hub. It is positioned according to the color difference around the gate fracture of the hub, so that the hub gate is aligned with the milling cutter mechanism 34. Then, the lifting mechanism 33 descends and the milling cutter mechanism 34 starts to perform finish machining on the fracture. The finish-machined hub is lifted by the lifting mechanism 33 and then taken into the next workstation by the workpiece conveying mechanism 1. It should be noted that in this embodiment, the angle of the hub is positioned by the color difference at the fracture. In other embodiments, the angle of the hub can also be positioned according to the color difference at the preset markings on the outer circumference of the hub. In other embodiments, the hub model can also be identified according to the markings on the outer circumference of the hub for the milling cutter mechanism 34 to automatically select the corresponding CNC machining program.

[0039] The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
