[0032] Embodiment 1

[0033] like Figure 1-2 as well as Figure 4 As shown, the utility model proposes a two-way deburring device for a wheel hub, which includes a base 2 as a mounting base, a support frame 4 fixedly connected to the base 2 through a plurality of support columns 3, a first rotating assembly 5 installed at one end of the support frame 4, a second rotating assembly 6 installed at the other end of the support frame 4, a grinding disc 7 respectively installed on the first rotating assembly 5 and the second rotating assembly 6 to grind and deburr the two surfaces of the wheel hub 1, and a positioning assembly 8 for supporting and stabilizing the wheel hub 1, specifically:

[0034] like Figure 1As shown, the support frame 4 includes a main frame arm 41, a first support arm 42 and a second support arm 43 respectively fixed at both ends of the main frame arm 41, and a third support arm 44 fixed to the middle section of the main frame arm 41. The lower surfaces of the first support arm 42, the second support arm 43 and the third support arm 44 are fixedly connected to the upper surface of the base 2 through the support column 3.

[0035] like Figure 1 As shown, the first rotating assembly 5 includes a first rotating motor 51 fixed to the first support arm 42, a rotating shaft 52 coaxially connected to the output shaft of the first rotating motor 51, and the rotating shaft 52 is fixedly connected to one of the grinding discs 7 and is rotatably connected to the first support arm 42 through a bearing. When the first rotating motor 51 is started, its output shaft drives the rotating shaft 52 to rotate, thereby driving the corresponding grinding disc 7 to rotate to grind and deburr the surface of the wheel hub 1.

[0036] like Figure 1 As shown, the second rotating assembly 6 includes a second motor 61 fixed to the second arm 43, a shaft cylinder 62 coaxially connected to the output shaft of the second motor 61, a threaded rotating shaft 63 slidably engaged with the shaft cylinder 62, and a screw ring 64 rotatably connected to the end of the shaft cylinder 62 and threadedly engaged with the threaded rotating shaft 63, and the shaft cylinder 62 is rotatably connected to the second arm 43 and the third arm 44 through a bearing. A guide slider 631 is fixedly connected to the outer wall of the threaded rotating shaft 63, and the shaft cylinder 62 is provided with a guide slot 621 for the guide slider 631 to slide. When the second motor 61 is started, its output shaft drives the shaft cylinder 62 to rotate, and the shaft cylinder 62 drives the threaded rotating shaft 63 to rotate through the engagement between the guide slot 621 and the guide slider 631, thereby driving another grinding disc 7 to rotate for grinding and deburring. In addition, when the screw ring 64 is rotated, the threaded rotating shaft 63 can be caused to translate to adjust the position of the grinding disc 7 connected to it through the threaded engagement between the screw ring 64 and the threaded rotating shaft 63.

[0037] like Figure 4 As shown, the positioning assembly 8 includes a pair of positioning rollers 81 and a pair of threaded columns 82 respectively arranged on both sides of the wheel hub 1.

When the threaded column 82 is rotated, the position of the positioning roller 81 can be adjusted through the threaded engagement between it and the screw sleeve 811, so that it is positioned against the wheel hub 1.

[0038] The working principle of this embodiment is: place the hub 1 on the base 2, rotate the threaded column 82 to adjust the position of the positioning roller 81, so as to simply limit the hub 1. Figure 2, one of the grinding discs 7 is located on the outside of the hub of the wheel hub 1, and the other grinding disc 7 is extended from the inner ring of the hub surface to the inside of the hub through the telescopic movement of the second rotating assembly 6. The first rotating motor 51 is started, and its output shaft drives the rotating shaft 52 to rotate, thereby driving the corresponding grinding disc 7 to rotate. The second motor 61 is started, and its output shaft drives the shaft cylinder 62 to rotate. The shaft cylinder 62 drives the threaded rotating shaft 63 to rotate through the engagement between the guide slide groove 621 and the guide slider 631, thereby driving the other grinding disc 7 to rotate. The inner and outer sides of the hub of the wheel hub 1 are respectively polished and deburred by the rotation of the two grinding discs 7.

[0039] Through the design of the first rotating component 5 and the second rotating component 6, the two grinding discs 7 can be driven at the same time to grind and deburr the two surfaces of the wheel hub 1 respectively, thereby improving the processing efficiency; and through the telescopic performance of the second rotating component 6, it is convenient to extend the grinding disc 7 from the inner ring of the hub surface of the wheel hub 1 to the inner side of the hub disc. In addition, its telescopic performance can adapt to wheel hubs 1 of different sizes and can continue to grind other surfaces after the direction of the wheel hub 1 is adjusted; the positioning component 8 can improve the placement stability of the wheel hub 1, thereby facilitating the grinding and deburring operation.

In combination with the first embodiment, only the hub surface needs to be manually polished, which improves the deburring efficiency. And when the wheel hub 1 is rotated, it can be positioned and guided by the two positioning rollers 81, simplifying the rotation operation.
