[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. When processing the hub, the present utility model presses the hub to be processed downward along the inner side of the positioning and placing plate. During the downward pressing process, the arc-shaped fixing block is driven to move inward. While the arc-shaped fixing block drives the connecting plate to move inward, it also drives the moving plate to move inward. When the moving plate moves inward, it drives the slider to move inward along the slide rail and at the same time squeezes the return spring inward. When the hub is pressed downward into the groove opened on the inner side of the positioning and placing plate, the resilience of the return spring makes the connecting plate continuously receive a force outward, and at the same time keeps the outer side of the arc-shaped fixing block firmly fixed to the inner side of the hub. When the hub is removed after processing, the separation plate and the separation fixing plate are toggled to the right. While the separation fixing plate drives the left moving plate and the slider to move to the right, it also drives the left linkage plate to turn inward. While the left linkage plate drives the swing plate to swing inward, it also drives the right linkage plate to turn left. While the right linkage plate drives the right moving plate and the slider to move to the left, it also drives the connecting plate and the arc-shaped fixing block to move inward. When the arc-shaped fixing block loses contact with the inner side of the hub, the hub can be removed. Thus, it has the advantage of facilitating the processing of the hub. Through the coordinated use of the fixing component, the moving component, the reset component, the linkage component and the manual separation component, the hub can be quickly positioned, fixed and separated, reducing the processing time of the hub.

[0014] 2. By setting the fixing component, the present utility model can quickly fix the hub, effectively avoiding the situation that the hub cannot be quickly fixed during processing and effectively improving the fixing efficiency of the hub. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Working principle and usage process of the present utility model: During use, when machining a hub, press the hub to be machined downward along the inner side of the positioning and placing plate 3. During the downward pressing process, the arc-shaped fixing block 51 is driven to move inward. While the arc-shaped fixing block 51 drives the connecting plate 52 to move inward, it also drives the moving plate 61 to move inward. When the moving plate 61 moves inward, it drives the slider 62 to move inward along the slide rail 63 and at the same time squeezes the return spring 72 inward. When the hub is pressed downward into the groove formed inside the positioning and placing plate 3, the resilience of the return spring 72 causes the connecting plate 52 to be continuously subjected to an outward force and at the same time keeps the outer side of the arc-shaped fixing block 51 firmly fixed to the inner side of the hub. When the hub is removed after machining, dial the separation plate 92 and the separation fixing plate 91 to the right. While the separation fixing plate 91 drives the left moving plate 61 and the slider 62 to move to the right, it also drives the left linkage plate 83 to flip inward. When the left linkage plate 83 drives the swing plate 81 to swing inward, it also drives the right linkage plate 83 to flip to the left. When the right linkage plate 83 drives the right moving plate 61 and the slider 62 to move to the left, it also drives the connecting plate 52 and the arc-shaped fixing block 51 to move inward. When the arc-shaped fixing block 51 loses contact with the inner side of the hub, the hub can be removed, thus having the advantage of facilitating the machining of the hub.

[0034] In summary: Through the combined use of the workbench 1, the support frame 2, the positioning and placing plate 3, the support column 4, the fixing component 5, the moving component 6, the reset component 7, the linkage component 8, and the manual separation component 9, this positioning and fixing device for hub machining solves the problem that the operator manually positions and fixes the hub, and a series of manual operations are required to remove the hub after machining, which increases the machining time of the hub.
