[0033] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the invention.

[0034] It should be noted that if the embodiments of the invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the invention.

[0036] In recent years, with the rapid development of automobile technology and in order to meet higher environmental protection requirements, the requirements for pistons have become increasingly higher. They must not only withstand higher explosion pressures, but also meet the thermal loads under high speeds and high functions. Therefore, when designing the piston, an annular cooling channel is usually added to the main high-load position of the head.

[0037] The piston material used in automobiles is mainly aluminum silicon material. The production of blank pistons mainly uses pure aluminum ingots and alloy ingredients to melt into aluminum liquid, inject it into the mold and cool it, and finally open the mold to get the blank. In order to make the annular cooling channel, it is necessary to put a prefabricated salt core before the aluminum alloy liquid enters the mold. When the aluminum alloy liquid enters the mold and fills and cools, it flows to the later process and then removes the prefabricated core, forming a cavity inside, namely the annular cooling channel. The process of removing the prefabricated salt core mainly includes the following: drilling in oil holes, drilling out oil holes, drilling pressure relief oil holes, and flushing the prefabricated salt core with high-pressure water;

[0038] At present, each of the above-mentioned processes is manually operated through an independent device, so each process requires one or more operators to operate, which leads to a large increase in the number of operators required in the whole process, thereby increasing labor costs. In order to reduce labor costs, the applicant has thought of integrating multiple processes into one production line and controlling them automatically, which can reduce the number of operators required, thereby reducing labor costs. Therefore, please refer to Figures 1 to 6The invention proposes a drilling production line 100, including a drilling device 1, a loading device 2, a discharging frame 3, a cleaning device 4 and a mechanical arm 5. The drilling device 1 is used to drill holes in a workpiece to be processed, the loading device 2 is used to transport the workpiece to be processed to the drilling device 1, the cleaning device 4 is used to clean the processed workpiece, the mechanical arm 5 is used to transport the processed workpiece on the drilling device 1 to the cleaning device 4, and the discharging frame 3 is used to collect the cleaned workpiece. The operator places the workpiece to be processed on the loading device 2 in sequence, the loading device 2 transports the workpiece to be processed to the drilling device 1, the drilling device 1 processes the workpiece to be processed, that is, punches holes in the workpiece to be processed, after the punching is completed, the mechanical arm 5 runs, clamps the processed workpiece and runs it to the cleaning device 4 for cleaning, after the cleaning is completed, the mechanical arm 5 transports the cleaned workpiece to the discharging frame 3, after a certain number of cleaned workpieces are accumulated in the discharging frame 3, the operator then transports the cleaned workpiece in the discharging frame 3 to the next process. In the technical solution of this embodiment, only one operator is needed to perform the loading operation, and the remaining steps are all automated without the intervention of operators, which greatly reduces the personnel quota and thus reduces labor costs.

[0039] Furthermore, the drilling production line 100 also includes a guardrail 7, which is arranged on the periphery of the drilling device 1, the feeding frame 3, the cleaning device 4 and the robotic arm 5, so as to prevent personnel from entering the operating area of ​​the robotic arm 5 during operation and protect the safety of the operators.

[0040] See also Figure 1 and Figure 2 In one embodiment, the loading device 2 includes a driving component 21, a base 22 and a synchronous belt component 23 disposed on the base 22. The synchronous belt component 23 includes a driving wheel, a driven wheel and a synchronous belt. The driving wheel and the driven wheel are connected by a synchronous belt transmission, and the output shaft of the driving component 21 is connected by a driving shaft. Specifically, the operator places the workpiece to be processed on the synchronous belt, starts the driving component 21, and the output shaft of the driving component 21 rotates, driving the driving wheel to rotate, so that the driven wheel will also rotate, and the synchronous belt will move, which will drive the workpiece to be processed placed on the synchronous belt to move toward the drilling device 1. By transporting the workpiece to be processed by the synchronous belt, long-distance transportation can be achieved, and the operator does not need to be too close to the operating range of the robot arm 5, which protects the safety of the operator. At the same time, the transportation of the synchronous belt reduces the vibration and impact during the operation, thereby improving the stability of the system.

[0041] See also Figure 1 and Figure 2In one embodiment, the feeding device 2 includes a height detection component 24, which is arranged on one side of the synchronous belt close to the drilling device 1. The height detection component 24 is used to detect the height of the workpiece to be processed, and the height detection component 24 is connected to the drive component 21 by signal. When the workpiece to be processed is placed at different angles and directions, the height of the workpiece to be processed is different. In order to ensure that the angle and direction of the workpiece to be processed are basically consistent, the height detection component 24 is set, so that when it is detected that the height of the workpiece to be processed deviates from the preset value, a signal will be sent to the drive component 21, so that the operation of the synchronous belt will be stopped, and the operator can manually adjust the direction and angle of the workpiece to be processed to ensure that the angle and direction of the workpiece to be processed are consistent, and ensure the accuracy of drilling.

[0042] See also Figures 1 to 3 In one embodiment, the drilling device 1 includes a moving component 16, a base 11, a turntable 12, a plurality of straight drilling components 13 and a plurality of oblique drilling components 15. The turntable 12 is rotatably mounted on the base 11. The plurality of straight drilling components 13 and the plurality of oblique drilling components 15 are all arranged on the base 11. A processing position 121 is arranged on the turntable 12. The moving component 16 is used to transport the workpiece to be processed on the feeding device 2 to the processing position 121; when the workpiece to be processed is located at one end of the synchronous belt facing the drilling device 1, the moving component 16 will clamp the workpiece to be processed and transport it to the processing position 121, and then drill the workpiece to be processed through the straight drilling component 13. After the processing is completed, the turntable 12 drives the workpiece to be processed to rotate to the oblique drilling component 15, and performs oblique hole processing on the workpiece to be processed. In this way, all drilling is completed. The above structure realizes the functions of automatic feeding and multi-angle drilling, which greatly improves the working efficiency.

[0043] Furthermore, there are multiple processing positions 121, so that multiple workpieces to be processed can be processed at the same time, which can further improve the working efficiency.

[0044] See also Figures 1 to 3 In one embodiment, the feeding device 2 further includes a sensor 25, which is arranged on the side of the synchronous belt close to the drilling device 1. The sensor 25 is used to detect whether there is a workpiece to be processed, and the sensor 25 is connected to the moving part 16 by signal. When the workpiece to be processed is transported to the synchronous belt close to the drilling device 1, the sensor 25 detects the existence of the workpiece to be processed, and thus transmits a signal to the moving part 16, and the moving part 16 starts to transport the workpiece to be processed to the processing position 121 for drilling. Such a setting can ensure that the moving part 16 will not run empty, thereby reducing energy consumption.

[0045] See also Figures 1 to 3In one embodiment, the drilling device 1 further includes a detection component 14, which is used to detect whether there is a workpiece to be processed at the processing position 121. When the workpiece to be processed is transported to the synchronous belt close to the drilling device 1, the sensor 25 detects the existence of the workpiece to be processed, so that a signal is transmitted to the moving component 16, and the moving component 16 starts to transport the workpiece to be processed to the processing position 121. The detection component 14 detects whether there is a workpiece to be processed on the processing position 121. If there is, the straight drilling component 13 and the angled drilling component 15 start to drill holes; this setting can prevent the straight drilling component 13 and the angled drilling component 15 from operating idle, thereby reducing energy consumption.

[0046] See also Figure 1 and Figure 4 In one embodiment, the robot arm 5 further includes a connecting plate 51 and two clamping jaws 52. The two clamping jaws 52 are both slidably mounted on the connecting plate 51 along the length direction of the connecting plate 51. The clamping jaws 52 are used to clamp the processed workpiece. The two clamping jaws 52 are slidably mounted on the connecting plate 51. When it is necessary to grab the processed workpiece, the clamping jaws 52 move on the connecting plate 51 to a suitable position. Then the clamping jaws 52 clamp the processed workpiece and move it to the cleaning device 4 for cleaning. The two clamping jaws 52 can clamp two processed workpieces at the same time or clamp a larger processed workpiece. In this way, the robot arm 5 can handle a larger number of processed workpieces and a larger size, which greatly improves the applicable range of the robot arm 5.

[0047] See also Figure 1 and Figure 4 In one embodiment, each clamping jaw component 52 includes a clamping cylinder 521 and two clamping jaws. The clamping cylinder 521 includes a cylinder body and two movable rods. The cylinder body is formed with a slide groove. The two movable rods are slidably installed in the slide groove. The two clamping jaws are respectively connected to the two movable rods. When it is necessary to clamp the processed workpiece, the two clamping jaws first slide along the slide groove, and the two clamping jaws move away from each other. Then, when moving to the processed workpiece, the two clamping jaws move closer to each other. When the two clamping jaws are respectively in contact with the two sides of the processed workpiece, the processed workpiece is clamped. The clamping function is realized by setting the clamping cylinder 521, which can provide a stable clamping force, and the pneumatic system responds quickly, and can complete the clamping and loosening actions in a short time. Compared with the hydraulic system, the pneumatic system has a relatively simple structure, is easier to maintain on a daily basis, and has a low maintenance cost.

[0048] See also Figure 1 and Figure 5In one embodiment, the drilling production line 100 further includes a flipping device 6, which includes a bracket 61, a waste bin 62 and a rotating component 63. The bracket 61 includes a placement rod 611, the waste bin 62 is arranged on the placement rod 611, and the rotating component 63 is installed on the bracket 61, and the rotating component 63 is located at the top of the waste bin 62, and the rotating component 63 is used to drive the processed workpiece to rotate. Specifically, after the drilling is completed, there will be a lot of dust and debris on the processed workpiece. The robot arm 5 clamps the processed workpiece and transports the processed workpiece to the flipping device 6, and then the rotating component 63 clamps the processed workpiece on the robot arm 5, and the rotating component 63 starts to rotate, and the debris and dust on the processed workpiece are poured into the waste bin 62, and then the robot arm 5 clamps the processed workpiece on the rotating component 63 again, and transports the processed workpiece to the cleaning device 4 for tilting. By setting the flipping device 6, the dust and debris can be cleaned in the first step to prevent a large amount of dust and debris from falling into the cleaning device 4.

[0049] See also Figure 1 and Figure 5 There are two rotating parts 63, and the two rotating parts 63 are arranged opposite to each other. In this way, when the size of the processed workpiece is large, the two rotating parts 63 respectively clamp one end of the processed part, and the two rotating parts 63 rotate at the same time to pour dust and debris into the waste box 62, so that the first step of cleaning of the large-sized processed workpiece can be achieved.

[0050] See also Figure 1 and Figure 5 In one embodiment, the rotating component 63 includes a rotary cylinder 631, a base plate 632 and a clamping subcomponent 633. The clamping subcomponent 633 is used to clamp the processed workpiece. The rotary cylinder 631 is installed on the bracket 61. The base plate 632 is connected to the output shaft of the rotary cylinder 631. The clamping subcomponent 633 is slidably installed on the base plate 632 along the vertical direction. The clamping subcomponent 633 moves to a suitable position along the vertical direction to clamp the processed workpiece on the robot arm 5. Then the output shaft of the rotary cylinder 631 rotates, which drives the base plate 632 to rotate, thereby rotating the clamping subcomponent 633 to achieve the removal of dust and debris.

[0051] See also Figure 1 and Figure 6In one embodiment, the cleaning device 4 includes a high-pressure pump 41, a water reservoir 42, a bottom plate 46 and a sewage pool 43. The bottom plate 46 is formed with a drainage channel, which is connected to the sewage pool 43. The high-pressure pump 41 is used to pump out the water in the water reservoir 42 for cleaning the processed workpiece. Specifically, after the robot 5 transports the processed workpiece to the cleaning device 4, the high-pressure pump 41 pumps out the water in the water reservoir 42 to clean the processed workpiece, remove dust and debris on the processed workpiece, and then the sewage will fall to the bottom plate 46, and then flow from the drainage pipe in the bottom plate 46 into the sewage pool 43 for collection. In this way, the processed workpiece can be cleaned and the sewage can be collected to prevent the sewage from flowing out, thereby ensuring the cleanliness of the factory.

[0052] See also Figure 1 and Figure 6 Furthermore, the cleaning device 4 also includes a drainage pump 45, which is used to pump out the sewage in the sewage pool 43. When the sewage in the sewage pool 43 is full, the drainage pump 45 is started to pump out the sewage in the sewage pool 43 and collect it, and then treat it uniformly. Through such a setting, it can be ensured that the sewage pool 43 can accommodate the sewage after cleaning in real time to prevent sewage overflow.

[0053] See also Figure 1 and Figure 6 Furthermore, the cleaning device 4 also includes a liquid level detection component 44, which is arranged in the sewage pool 43. The liquid level detection component 44 is connected to the drainage pump 45 signal. The liquid level detection component 44 detects that the sewage has risen to the liquid level detection component 44, so that the signal will be transmitted to the drainage pump 45, thereby starting the drainage pump 45 to discharge the sewage, ensuring that the sewage in the sewage pool 43 will not be in the liquid level detection component 44, ensuring that the sewage pool 43 can always accommodate sewage.
