[0062] The second finishing device 24 is used for finishing the second surface 32 of the workpiece 3 .

[0063] In order to improve the processing efficiency and quality of automobile engine transmission cover, this technical solution proposes a processing production line for automobile engine transmission cover, such as Figure 1-13As shown, it includes a rough processing production line and a fine processing production line arranged in sequence along the processing procedures. By adding a rough processing transfer robot to transfer the products to be processed in various equipment in the rough processing procedure, and at the same time adding a fine processing transfer robot to transfer the products to be processed in various equipment in the fine processing procedure, it is beneficial to optimize the layout of the processing production line, thereby improving the processing efficiency and processing quality of the automobile engine transmission cover, so as to overcome the shortcomings of the prior art.

[0064] Specifically, the rough processing production line of the present scheme includes a loading mechanism 11, a return conveyor belt 12, a first rough processing equipment 13, a rough processing semi-finished product transfer table 14, a second rough processing equipment 15 and a rough processing transfer robot 16, and its working process is as follows: First, the operator loads the workpiece 3 to the loading mechanism 11, and uses the blank detection component 113 in the loading mechanism 11 to perform quality inspection on the workpiece 3. Only the blanks that pass the inspection can enter the next process for rough processing, and the blanks that fail the inspection need to be transferred to the return conveyor belt 12 for return processing, so as to prevent the structural differences of the products to be processed obtained after casting demolding are relatively large, resulting in the processing fixtures used in the processing process being difficult to achieve the above-mentioned product to be processed. The phenomenon of stable clamping can also reduce the entry of defective blanks into the processing production line and avoid wasting processing resources. The automobile engine transmission cover generally needs to be processed on its first surface 31 and second surface 32 which are arranged opposite to each other. After the qualified blank is transferred to the first rough processing equipment 13 by the rough processing transfer robot 16, the first rough processing equipment 13 performs rough processing on the first surface 31 of the workpiece 3 (including rough processing such as milling, drilling, and boring); and then the product after rough processing on the first surface 31 is placed on the rough processing semi-finished product transfer table 14, so that the rough processing transfer robot 16 can clamp the second surface 32 of the product and transfer it to the second rough processing equipment 15 for rough processing of the second surface 32. After the second surface 32 is processed, the rough processing transfer robot 16 places the product on the rough processing finished product turning table 21, waiting to enter the finishing production line.

[0065] Furthermore, the finishing production line of this solution includes a roughing finished product turning 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 conveyor belt 26 and a finishing transfer robot 27. Since in the finishing processing steps, the finishing of the automobile engine transmission cover also requires the first surface 31 to be processed first, and then the second surface 32 to be processed, therefore, this solution adds a turning function to the transfer table (i.e., the roughing finished product turning table 21) connected to the roughing production line and the finishing production line, so as to facilitate the smooth progress of subsequent processes. The working process of the finishing production line of this scheme is as follows: use the rough-finished product turning table 21 to turn the first side 31 of the workpiece 3 upward, and then use the finishing transfer robot 27 to transfer it in sequence between the rough-finished product turning table 21, the first finishing equipment 22, the finishing semi-finished product transfer table 23 and the second finishing equipment 24 to complete the finishing of the first side 31 and the second side 32 (including finishing treatments such as milling, drilling, and boring); finally, after cleaning in the cleaning box 5, place it on the discharge conveyor belt 26 for product unloading.

[0066] It should be noted that the first rough processing equipment 13, the second rough processing equipment 15, the first fine processing equipment 22 and the second fine processing equipment 24 of this solution are all existing special processing equipment, and their structures are not described in detail here. The blank detection component 113 of this solution can be a detection equipment commonly used by automobile parts companies.

[0067] Further, the finishing production line further includes a ground rail 28, the finishing transfer robot 27 is installed on the ground rail 28, and the finishing transfer robot 27 moves along the extension direction of the ground rail 28;

[0068] The rough-processed finished product turning table 21 is arranged near one end of the ground rail 28, and the discharge conveyor belt 26 is arranged near the other end of the ground rail 28;

[0069] There are two of each of the first finishing equipment 22 and the second finishing equipment 24; the two first finishing equipment 22 are arranged on both sides of the ground rail 28 along the extension direction, and the first finishing equipment 22 is arranged close to the rough-finished product turning table 21; the two second finishing equipment 24 are arranged on both sides of the ground rail 28 along the extension direction, and the second finishing equipment 24 is arranged close to the discharge conveyor belt 26.

[0070] In addition, if Fig.11As shown, in order to further improve the processing efficiency of the automobile engine transmission cover, the present solution also adds two sets of finishing equipment in the finishing production line (a first finishing equipment 22 and a second finishing equipment 24 form a set of finishing equipment), and widens the transfer range of the finishing transfer robot 27 through the ground rail 28, so that the various steps of the finishing production line can be matched and coordinated with each other.

[0071] Further, the feeding mechanism 11 includes a multi-station feeding bin assembly 111, a transfer assembly 112 and the blank detection assembly 113 which are sequentially arranged along the unloading direction, and the transfer assembly 112 is used to transfer the workpiece 3 of the multi-station feeding bin assembly 111 to the blank detection assembly 113;

[0072] The multi-station loading bin assembly 111 is provided with a plurality of loading fixtures 1111 , and the plurality of loading fixtures 1111 move in a circular direction on the top of the multi-station loading bin assembly 111 .

[0073] like Figure 2-3 As shown, the feeding mechanism 11 of the present solution includes a multi-station feeding bin assembly 111, a transfer assembly 112 and a blank detection assembly 113 which are sequentially arranged along the unloading direction, wherein the multi-station feeding bin assembly 111 is provided with a plurality of feeding fixtures 1111. The feeding process of the feeding mechanism 11 in the present solution is as follows: the operator feeds the workpiece 3 to the feeding fixture 1111, and then the feeding fixture 1111 moves circumferentially on the top of the multi-station feeding bin assembly 111 and moves to the bottom of the transfer assembly 112, and then the transfer assembly 112 transfers the workpiece 3 on the feeding fixture 1111 to the blank detection assembly 113 for quality inspection. Since the feeding mechanism 11 of the present solution has a multi-station feeding bin assembly 111, the multi-station feeding bin assembly 111 can continuously provide sufficient product blanks to the transfer assembly 112 to improve the feeding rhythm of the processing production line.

[0077] like Figure 4-5As shown, the multi-station loading bin assembly 111 of the present solution also includes a circular track 1112 and a slider 1113, and a loading tool 1111 is connected between two adjacent sliders 1113, and the movement of the slider 1113 drives the movement of the loading tool 1111, so as to facilitate smooth operation.

[0078] Preferably, guide grooves 11121 are provided on both sides of the annular track 1112 , bearings 11131 are protrudingly provided on both sides of the bottom of the slider 1113 , and the bearings 11131 rotate around their own axes relative to the slider 1113 , and the bearings 11131 are accommodated in the guide grooves 11121 .

[0079] like Figure 6-7 As shown, this is helpful to prevent the slider 1113 from derailing and further improve the stability of the circumferential movement of the slider 1113.

[0080] Preferably, the multi-station loading bin assembly 111 further includes a driving sprocket 1114, a driven sprocket 1115 and a transmission chain 1116, wherein the driving sprocket 1114 and the driven sprocket 1115 are installed inside the annular track 1112 at intervals, and the transmission chain 1116 is wound around the outside of the driving sprocket 1114 and the driven sprocket 1115;

[0081] The driving sprocket 1114 and the driven sprocket 1115 can both rotate relative to the annular track 1112, and the rotation of the driving sprocket 1114 drives the rotation of the transmission chain 1116, and the rotation of the driving sprocket 1114 drives the rotation of the driven sprocket 1115 through the transmission chain 1116;

[0082] A connecting block 11132 is protrudingly provided on the inner side of the sliding block 1113 . The connecting block 11132 is connected to the transmission chain 1116 . The rotation of the transmission chain 1116 drives the movement of the sliding block 1113 .

[0083] like Figure 4-6 As shown, this solution utilizes chain transmission to drive the slider 1113 to move synchronously along the extension direction of the annular track 1112, which is beneficial to improving the accuracy of the annular movement and facilitating the transfer component 112 to accurately clamp the workpiece 3 in the loading tooling 1111.

[0084] Further, the multi-station loading bin assembly 111 further includes a material unloading positioning assembly 1117, and the material unloading positioning assembly 1117 includes a material unloading positioning block 11171 and a positioning lifting plate 11172;

[0085] The blanking positioning block 11171 is protrudingly arranged on the outer side of the sliding block 1113;

[0086] The positioning lifting plate 11172 is located on the outside of the unloading end of the circular track 1112, and the positioning lifting plate 11172 is located between the multi-station loading bin assembly 111 and the transfer assembly 112; the positioning lifting plate 11172 can move up and down relative to the circular track 1112, and a positioning groove for accommodating the unloading positioning block 11171 is provided on the top of the positioning lifting plate 11172.

[0087] like Figure 7 As shown, in order to enable the loading tool 1111 to accurately convey the workpiece 3 to the right below the transfer assembly 112, so that the transfer assembly 112 can effectively clamp the product to be processed, the present solution also adds a material unloading positioning assembly 1117 to the multi-station loading bin assembly 111. When the workpiece 3 is conveyed to the vicinity of the transfer assembly 112, the positioning lifting plate 11172 is raised and positioned with the material unloading positioning block 11171, thereby accurately positioning the workpiece 3.

[0090] like Figure 2-3 As shown, the transfer assembly 112 of the present scheme includes a lifting seat 1121, a rotating arm 1122 and a pneumatic clamp 1123, and the rotating arm 1122 can rotate relative to the circular track 1112, and can also move up and down relative to the circular track 1112 through the lifting seat 1121, thereby conveniently realizing the transfer of the workpiece 33 from the multi-station loading bin assembly 111 to the blank detection assembly 113.

[0091] Further, the rough processing transfer robot 16 includes a six-axis mechanical arm 161, a mounting plate 162, a first clamping jaw 163 and a second clamping jaw 164, wherein the mounting plate 162 is mounted on the output end of the six-axis mechanical arm 161, and the first clamping jaw 163 and the second clamping jaw 164 are respectively mounted on both sides of the mounting plate 162;

[0105] Furthermore, in order to make it more convenient for the finishing transfer robot 27 to pick up materials, the rotary tooling 213 of the present solution can also rotate along its own axis to accommodate the material picking angle of the finishing transfer robot 27 .

[0106] Preferably, the rough finished product turning table 21 includes a spray head and a water receiving tank 214, the inlet of the spray head is connected to the water source, and the outlet of the spray head is located above the interior of the box 211; a plurality of the spray heads are provided, and the plurality of the spray heads are evenly distributed around the edge of the box 211;

[0107] A drainage port 2112 is formed at the center of the bottom of the box body 211 , and the water receiving tank 214 is disposed below the drainage port 2112 .

[0108] Furthermore, since the surface of the product after rough processing will have debris, in order to improve the processing accuracy of fine processing, the present solution can use a spray head (not shown in the figure) to clean the rough processed product in the rough processed product turning table 21, and add a water receiving trough 214 in the rough processed product turning table 21 to receive the cleaning wastewater.

[0109] Preferably, the water receiving tank 214 includes a filter plate 2141 and a water receiving plate 2142 which are sequentially arranged from top to bottom, and a plurality of evenly distributed filter holes are formed at the bottom of the filter plate 2141 .

The fixed plate 272 is installed at the output end of the six-axis manipulator 271. There are two clamping members 273, and the two clamping members 273 are respectively installed on both sides of the fixed plate 272.

[0112] like Fig.13 As shown, the finishing transfer robot 27 of the present solution includes a six-axis manipulator 271, a fixed plate 272 and two clamps 273, and the two clamps 273 are respectively installed on both sides of the fixed plate 272, which is beneficial to speed up the loading and unloading speed of each equipment in the finishing production line.

[0113] In a specific embodiment, when a processed product A is placed inside the first finishing equipment 22, and the finishing transfer robot 27 clamps a product B that is ready to enter the first finishing equipment 22 for processing, the finishing transfer robot 27 can use the remaining clamping parts 273 that do not clamp any products to first take product A out of the first finishing equipment 22, and then immediately place product B inside the first finishing equipment 22 for processing, thereby speeding up the loading and unloading speeds of each equipment in the finishing production line, and then improving the processing efficiency of the finishing production line.

[0114] Further explained, the clamping member 273 includes a three-jaw positioning clamp 2731 and a linear clamp 2732, and the three-jaw positioning clamp 2731 and the linear clamp 2732 are spaced apart on one side of the fixed plate 272, and the clamping surface of the three-jaw positioning clamp 2731 is used to abut against the positioning hole 33 of the workpiece 3, and the clamping surface of the linear clamp 2732 is used to abut against the side wall of the workpiece 3.
