[0063] In order to improve the machining efficiency and machining quality of the automobile engine gearbox cover, the technical solution provides a machining production line for an automobile engine gearbox cover, as shown in Figures 1-13As shown, the rough machining production line and the finish machining production line are arranged in sequence along the machining process, the rough machining transfer robot is additionally arranged to transfer the product to be machined among the devices in the rough machining process, and the finish machining transfer robot is additionally arranged to transfer the product to be machined among the devices in the finish machining process, which is beneficial to optimize the layout of the machining production line, thereby improving the machining efficiency and machining quality of the automobile engine gearbox cover, and overcoming the shortcomings in the prior art.

[0064] Specifically, the rough machining production line of the present scheme comprises a feeding mechanism 11, a material return conveyor belt 12, a first rough machining device 13, a rough machining semi-finished product transfer table 14, a second rough machining device 15 and a rough machining transfer robot 16, and the working process is as follows: first, the operator feeds the workpiece 3 to the feeding mechanism 11, and uses the blank detection assembly 113 in the feeding mechanism 11 to detect the quality of the workpiece 3, only the qualified blank can enter the next process for rough machining, and the unqualified blank needs to be transferred to the material return conveyor belt 12 for material return treatment, so as to prevent the phenomenon that the machining clamp used in the machining process is difficult to realize the accurate and stable clamping of the product to be machined due to the large structural difference of the product to be machined obtained after casting demolding, and to reduce the entry of defective blanks into the machining production line and avoid waste of machining resources. The automobile engine gearbox cover generally needs to process the first face 31 and the second face 32 arranged opposite to each other, and after the qualified blank is transferred to the first rough machining device 13 by the rough machining transfer robot 16, the first rough machining device 13 performs rough machining (including rough processing steps such as face milling, drilling and boring) on the first face 31 of the workpiece 3; then the product after rough machining of the first face 31 is placed on the rough machining semi-finished product transfer table 14, so that the rough machining transfer robot 16 clamps the second face 32 of the product and transfers it to the second rough machining device 15 for rough machining of the second face 32. After the second face 32 is machined, the product is placed on the rough machining finished product turnover table 21 by the rough machining transfer robot 16, and waits to enter the finish machining production line.

[0065] Further, the finishing production line of the scheme comprises a rough-finished product turnover table 21, a first finishing equipment 22, a finishing semi-finished product transfer table 23, a second finishing equipment 24, a cleaning box 25, a discharge conveying belt 26 and a finishing transfer robot 27. Since the finishing of the automobile engine gearbox cover also needs to process the first face 31 first and then process the second face 32 in the finishing process, the scheme adds a turnover function to the transfer table (i.e. the rough-finished product turnover table 21) connected to the rough production line and the finishing production line, so as to facilitate the smooth progress of the subsequent process. The working process of the finishing production line of the scheme is as follows: the first face 31 of the workpiece 3 is turned over to face upwards by using the rough-finished product turnover table 21, and then the finishing transfer robot 27 is used to transfer between the rough-finished product turnover table 21, the first finishing equipment 22, the finishing semi-finished product transfer table 23 and the second finishing equipment 24 in sequence, so as to complete the finishing (including finishing processes such as face milling, drilling and boring) of the first face 31 and the second face 32; finally, after cleaning by the cleaning box 5, the product is placed on the discharge conveying belt 26 for product discharge.

[0066] It should be noted that the first rough finishing equipment 13, the second rough finishing equipment 15, the first finishing equipment 22 and the second finishing equipment 24 of the scheme are all existing special-purpose machining equipment, and their structures will not be described in detail here.
