Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automobile powertrain housing parts clamp. Background Art

[0002] In the manufacturing process of automobile powertrain, a complex housing part (such as Figure 1 As shown in the figure, the part has completed the processing of a hole with a diameter of 120mm and its end face, a hole with a diameter of 97H7, an outer circle with a diameter of 100f7 and its end face. However, the current task is to process a hole with a diameter of 52H7. This step is crucial to the performance and accuracy of the entire part. Due to the complex structural design of the part, it contains multiple holes and outer circles with different diameters and accuracy, which greatly increases the difficulty of subsequent processing. A further challenge is that the part is a thin-walled design with poor rigidity. During the processing, this lack of rigidity can easily cause the part to deform due to uneven force, which directly affects the processing accuracy.

[0003] In the prior art, for the processing of complex housing parts in automobile powertrain, especially when it is necessary to process a hole with a diameter of 52H7, a four-axis CNC machining center is usually used based on the marking and alignment method. However, this processing method has significant defects and shortcomings when facing the above-mentioned part characteristics and requirements, mainly manifested in poor processing accuracy and low efficiency.

[0004] First, the marking and alignment processing method relies on manual marking and alignment, which itself introduces large human errors. Especially when processing complex structural parts, the accuracy of marking and alignment is difficult to guarantee due to the various shapes and sizes of the parts. In addition, since the parts are thin-walled and have poor rigidity, the parts may be deformed due to uneven force during the marking and alignment process, further reducing the processing accuracy.

[0005] Secondly, the marking and alignment processing method is inefficient. Before processing, multiple steps such as marking, alignment and debugging are required, all of which require a lot of manpower and time. At the same time, since the processing accuracy is difficult to guarantee, multiple rework and corrections may be required, further reducing production efficiency. In a highly automated modern manufacturing environment, this processing method that relies on manual and repetitive labor is obviously unable to meet production needs. Utility Model Content
