[0043] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0044] The present technical solution provides a rough processing production line for automobile engine transmission covers, comprising a loading mechanism 11, a material return conveyor belt 12, a first rough processing device 13, a rough processing semi-finished product transfer table 14, a second rough processing device 15, and a rough processing transfer robot 16, wherein the loading mechanism 11, the material return conveyor belt 12, the first rough processing device 13, the rough processing semi-finished product transfer table 14, and the second rough processing device 15 are all located within the transfer range of the rough processing transfer robot 16;

[0045] The feeding mechanism 11 includes a blank detection component 113, and the blank detection component 113 is used to detect the workpiece 3;

[0046] The first rough machining device 13 is used to perform rough machining on the first surface 31 of the workpiece 3;

[0047] The second rough machining device 15 is used to perform rough machining on the second surface 32 of the workpiece 3 .

[0048] In order to improve the rough machining efficiency and machining quality of automobile engine transmission cover, this technical solution proposes a rough machining production line for automobile engine transmission cover, such as Figure 1-10 As shown, by adding a rough processing transfer robot to transfer the products to be processed between various equipment in the rough processing process, it is beneficial to optimize the layout of the rough processing production line, thereby improving the rough processing efficiency and processing quality of the automobile engine transmission cover, so as to overcome the shortcomings of the existing technology.

[0049] Specifically, the rough processing production line of this 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 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 accurate and stable clamping of the above-mentioned products to be processed. It can also reduce the number of bad blanks entering the rough processing production line and avoid wasting processing resources. An automobile engine transmission cover typically requires machining of its opposing first and second surfaces 31 and 32. After a qualified workpiece is transferred by the rough machining transfer robot 16 to the first rough machining equipment 13, the first rough machining equipment 13 performs rough machining (including milling, drilling, and boring) on ​​the first surface 31 of the workpiece 3. The rough-machined product is then placed on the rough-machined semi-finished product transfer table 14, allowing the rough machining transfer robot 16 to grasp the second surface 32 and transfer it to the second rough machining equipment 15 for rough machining. After machining the second surface 32, the workpiece waits for the next machining step (such as finishing).

[0050] It should be noted that the first rough processing equipment 13 and the second rough processing equipment 15 of this solution are both existing special processing equipment, and their structures are not described in detail here. The blank detection component 113 of this solution can be a commonly used detection equipment in automobile parts companies.

[0051] Further, the loading mechanism 11 includes a multi-station loading bin assembly 111, a transfer assembly 112 and the blank detection assembly 113 arranged in sequence along the unloading direction, and the transfer assembly 112 is used to transfer the workpiece 3 of the multi-station loading bin assembly 111 to the blank detection assembly 113;

[0052] 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 .

[0053] like Figure 2-3As shown, the loading mechanism 11 of this solution includes a multi-station loading 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 loading bin assembly 111 is provided with a plurality of loading fixtures 1111. The loading process of the loading mechanism 11 in this solution is as follows: the operator loads the workpiece 3 onto the loading fixture 1111, and then the loading fixture 1111 moves circumferentially at the top of the multi-station loading 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 loading fixture 1111 to the blank detection assembly 113 for quality inspection. Since the loading mechanism 11 of this solution has a multi-station loading bin assembly 111, the multi-station loading bin assembly 111 can continuously provide sufficient product blanks to the transfer assembly 112, thereby improving the loading rhythm of the rough processing production line.

[0054] To further illustrate, the multi-station loading bin assembly 111 further includes a ring track 1112 and a slider 1113;

[0055] There are multiple sliders 1113 , and the multiple sliders 1113 are evenly spaced and installed on the top of the annular track 1112 , and the multiple sliders 1113 move synchronously along the extension direction of the annular track 1112 ;

[0056] The loading tool 1111 is installed on the top of the slider 1113 , and one 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 .

[0057] like Figure 4-5 As shown, the multi-station loading bin assembly 111 of this solution also includes a ring track 1112 and a slider 1113, and a loading tool 1111 is connected between two adjacent sliders 1113. The movement of the slider 1113 drives the movement of the loading tool 1111, which facilitates smooth operation.

[0058] To further explain, guide grooves 11121 are provided on both sides of the annular track 1112, and 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.

[0059] 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.

[0060] To further illustrate, the multi-station loading bin assembly 111 further includes a driving sprocket 1114, a driven sprocket 1115, and a transmission chain 1116. 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.

[0061] 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;

[0062] A connecting block 11132 is protruding from the inner side of the slider 1113 . The connecting block 11132 is connected to the transmission chain 1116 . The rotation of the transmission chain 1116 drives the movement of the slider 1113 .

[0063] 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.

[0064] To further illustrate, the multi-station loading bin assembly 111 further includes a blanking positioning assembly 1117 , and the blanking positioning assembly 1117 includes a blanking positioning block 11171 and a positioning lifting plate 11172 ;

[0065] The blanking positioning block 11171 is protrudingly arranged on the outer side of the sliding block 1113;

[0066] 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 at the top of the positioning lifting plate 11172.

[0067] like Figure 7As shown, in order to ensure that the loading fixture 1111 accurately delivers the workpiece 3 to the position directly below the transfer assembly 112, thereby facilitating the transfer assembly 112 to effectively grip the product to be processed, this solution also adds a blanking positioning assembly 1117 to the multi-station loading bin assembly 111. When the workpiece 3 is delivered to the vicinity of the transfer assembly 112, the positioning lifting plate 11172 rises and aligns with the blanking positioning block 11171, thereby accurately positioning the workpiece 3.

[0068] To further illustrate, the transfer assembly 112 is located at the unloading end of the multi-station loading bin assembly 111;

[0069] The transfer assembly 112 includes a lifting seat 1121, a rotating arm 1122 and a pneumatic clamp 1123. The lifting seat 1121 can move up and down relative to the circular track 1112. The first mounting end of the rotating arm 1122 is installed on the top of the lifting seat 1121. The second mounting end of the rotating arm 1122 is installed with the pneumatic clamp 1123. The rotating arm 1122 can rotate relative to the lifting seat 1121. The pneumatic clamp 1123 is used to clamp the workpiece 3.

[0070] like Figure 2-3 As shown, the transfer assembly 112 of this 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.

[0071] To further illustrate, the rough processing transfer robot 16 includes a six-axis robotic arm 161, a mounting plate 162, a first clamping jaw 163, and a second clamping jaw 164. The mounting plate 162 is mounted on the output end of the six-axis robotic 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.

[0072] The first clamping jaw 163 is used to clamp the workpiece 3 with the first surface 31 of the workpiece 3 facing inward;

[0073] The second clamping jaw 164 is used to clamp the workpiece 3 with the second surface 32 of the workpiece 3 facing inward.

[0074] like Figure 8-10As shown, the rough processing transfer robot 16 of this solution includes a six-axis robotic arm 161, a mounting plate 162, a first clamp 163 and a second clamp 164, and the first clamp 163 for making the first surface 31 face inward and the second clamp 164 for making the second surface 32 face inward are respectively installed on both sides of the mounting plate 162, so that only one rough processing transfer robot 16 is needed to complete all the transfer work in the rough processing production line, thereby reducing the processing cost.

[0075] Further, the rough processing transfer robot 16 also includes a spring pin 165, which is protrudingly arranged on one side of the mounting plate 162, and the spring pin 165 and the first clamp 163 are located on the same side of the mounting plate 162; the end of the spring pin 165 is used to support the first surface 31 of the workpiece 3.

[0076] like Figure 9-10 As shown, this solution further provides a device near the first clamping jaw 163 for supporting the first surface 31 of the workpiece 3 so as to match with a conventional clamp of the first rough processing equipment 13 for rough processing the first surface 31 .

[0077] To further illustrate, at least two spring pins 165 are provided, and the two spring pins 165 are respectively located on both sides of the first clamping jaw 163. This is conducive to keeping the workpiece 3 balanced at all times during the clamping process.
