A kind of aluminum alloy wheel punching process

Abstract

The invention relates to a process for drilling aluminum alloy wheels. The specific steps are as follows: (1) installing a drill bit; (2) clamping a workpiece; (3) installing a punching template; (4) using a multi-axis device to punch holes; (5) ) to move the workpiece chuck; (6) to use a multi-axis device for tapping; (7) to complete the processing and unload the wheel workpiece. The single-piece processing of products produced by this process saves 1 minute and 10 seconds, effectively improves the processing efficiency of machining, reduces the scrap caused by hole deviation, improves the production efficiency and pass rate of machining, increases output, and reduces production costs.

Description

technical field [0001] The invention belongs to the field of processing aluminum alloy wheels, in particular to a drilling process for aluminum alloy wheels. Background technique [0002] At present, with the rapid development of the automobile industry, the order volume of wheel products continues to increase, which puts forward higher requirements for product quality and production efficiency. One of the processing bottlenecks in production is the large number of insert holes in the center machine, which affects the processing efficiency. The existing processing method relies on the existing machining center to process each insert hole one by one with a drill bit, and the processing efficiency is low. It takes a long time, and the hole of the insert is easy to deviate after processing, which leads to poor appearance of the insert after fitting, reduces the output of the machining production class, and increases the production cost. [0003] Moreover, the requirements for ...

One of the processing bottlenecks in production is the large number of insert holes in the center machine, which affects the processing efficiency. The existing processing method relies on the existing machining center to process each insert hole one by one with a drill bit, and the processing efficiency is low. It takes a long time, and the hole of the insert is easy to deviate after processing, which leads to poor appearance of the insert after fitting, reduces the output of the machining production class, and increases the production cost

[0003] Moreover, the requirements for the balance of the product are more stringent. After the products produced by the existing processing methods are machined, the products often have the problem of out-of-tolerance balance, resulting in waste products, and the production efficiency is also low. After searching for the reasons, it is found that the main reason is that the current machine During processing, the fixture positioning method of the wheel product leads to insufficient positioning accuracy of the machining center of the product

[0004] The radial positioning method of the existing blank fixture is the inner positioning and outer positioning of the outer rim, and the positioning method of the three-point cylinder manual adjustment is adopted. The main problems are as follows: (1) The three-point blank thin-wall positioning, the blank lugs are radially stressed , the deformation of the blank is large, which affects the machining accuracy and the product performance after processing; (2) The three positioning blocks manually adjust the radial position, there is a certain error, and the three points cannot be guaranteed to be concentric. In order to ensure easy installation of the card, the positioning block There is a certain gap between the blank and the blank, resulting in a clearance fit between the positioning block and the blank surface; (3) The shape of the three positioning blocks is cylindrical, and the positioning method is 3-point positioning, and the radial position is manually passed through the meter. There is a certain error, and it is impossible to ensure that the three positioning points are concentric, and the blank can still be clamped when the positioning column is not concentric, resulting in the blank being not concentric with the lathe spindle
