Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is described in detail, a kind of finish machining fine polishing process, as figure 1 shown, including the following steps:

[0020] Step One: Check the Measurements. 100% inspection of the appearance of semi-finished products, separate stacking of unqualified products in standard definition, and 100% measurement of wheel width processing of semi-finished products;

[0021] The second step: infinite mark. Before finishing turning, after measuring with a measuring tool, it is judged as a product that can be processed, but there is no repair allowance, use a paint pen to touch the weight-reducing pocket of the back cavity, and confirm that it is an infinite repair product;

[0022] The third step: steel number printing. For the semi-finished products that meet the processing requirements, print the marking numbers in sequence;

[0023] Step 4: Confirm the program. Before processing the first piece...

Abstract

The invention discloses a finish machining and finish polishing process. The process comprises the steps of 1 100% inspection is carried out on the appearance of a semi-finished product; 2 before finish turning, measuring is carried out by using a measuring tool; 3 a mark number is printed on the semi-finished product meeting the processing requirement; 4 before a first workpiece is machined, whether the program name conforms to the machining wheel type name or not and whether the used tool and tool compensation are correct or not are determined; 5 an operator grasps a spoke window with the right hand and supports the rim with the left hand, a center hole of the product is aligned and perpendicular to a second-order mandrel, and a first-order wheel lip makes contact with an end face blockcompletely and then is clamped; 6 when trial rotation is conducted, a door is in a semi-closed state, and machining is started after it is confirmed that rotation has no obvious bounce; 7 the workpiece is taken down and placed on a burr frame; 8 self-inspection is conducted; and 9 burrs are removed. The method has the beneficial effects that the material quality and the part precision can be improved, and the durability is improved during use.

Description

technical field [0001] The invention relates to the field of finishing, in particular to a finishing and polishing process. Background technique [0002] The wheel hub is one of the most important safety parts on the car. It can be divided into steel wheel hub and aluminum wheel hub. Irregular alternating forces generated by dynamic loads from different directions such as turning of the car during the form process, bumpy road surface, road obstacle impact, etc. The quality and reliability of the wheel not only affect the safety of the vehicle and the personnel and materials on the vehicle, but also affect the stability, maneuverability, comfort and other performance of the vehicle during driving. This requires the wheel hub to have good dynamic balance, high fatigue strength, With good rigidity and elasticity, high precision of size and shape, light weight, etc., the aluminum wheel hub meets the above requirements with its good comprehensive performance, and has outstanding...
