[0008] In an embodiment of the present disclosure, the tapping device for forgings further includes: a protective cover, which is arranged on the bench and surrounds the forging fixing table, and one end of the protective cover away from the bench is an opening.
[0009] By arranging a protective cover on the bench that can surround the forging fixing table, it is possible to effectively reduce the splashing of debris during tapping when the tapping device processes forgings, reduce the difficulty and workload of cleaning debris, and reduce the possibility of debris injuring people.

[0015] By configuring the second support column, the imaging device, the control device, the first motor, the second motor, and the third motor, and by setting a tapping mark on the forging, the tapping device can automatically identify the tapping mark on the forging, and thus adjust the position of the tapping machine by controlling the first motor, the second motor, and the third motor, so that the tapping position of the tapping machine is aligned with the tapping mark on the forging. In this way, the automatic adjustment of the position of the tapping machine according to the tapping mark on the forging is realized, which is beneficial to the automation of the entire process of tapping the forging. In addition, it is easier to have a large error when manually adjusting the tapping position of the tapping machine. The method of automatically adjusting the tapping position of the tapping machine by using the imaging device, the control device, the first motor, the second motor, and the third motor is more stable, accurate, and reliable, thereby improving the yield rate of the finished product after tapping the forging.

[0019] In an embodiment of the present disclosure, the imaging device is slidably arranged on the second support column; the tapping device for the forging further includes: a fourth motor for controlling the movement of the imaging device on the second support column; the control device is further used to control the fourth motor according to a predetermined control strategy.
[0020] By sliding the photographing device on the second support column and controlling the movement of the photographing device through a control device, it is possible to move the picture of the tapping mark on the forging to control the alignment of the tapping position of the tapping machine with the position where the tapping mark is located in the case of different forging shapes and the tapping machine blocking the tapping mark.
[0021] In an embodiment of the present disclosure, the control device is further configured to determine whether the positional relationship between the tapping mark and the tapping machine meets the tapping start condition according to the picture taken by the photographing device after the first motor, the second motor, and the third motor complete the control instruction; when the positional relationship between the tapping mark and the tapping machine does not meet the tapping start condition, the control device regenerates the control instructions for controlling the first motor, the second motor, and the third motor respectively according to the positional relationship between the tapping mark and the tapping machine.

[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more complete and comprehensive, and will fully convey the concept of the example embodiments to those skilled in the art. The features, structures, or characteristics described may be combined in any suitable manner in one or more embodiments.
[0031] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repeated description will be omitted. It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different air conditioner indoor units, pipelines, or electric valves.
[0032] As Figure 1 shown, the tapping device for forgings in the embodiment of the present disclosure may include: a bench 1, a first support column 2, a forging fixing table 3, a fixing frame 4, a cross plate 5, and a tapping machine 6.
[0033] Among them, the support column 2 is provided on the bench 1, the forging fixing table 3 is provided on the bench 1, and a forging fixing device 301 for fixing the forging is provided on the forging fixing table 3.
[0034] The fixing frame 4 is slidably provided on the first support column 2, the cross plate 5 is slidably provided within the frame of the fixing frame 4, and the tapping machine 6 is slidably provided on the cross plate 5.
[0035] Regarding how the fixing frame 4 is slidably provided on the first support column 2, the disclosed embodiments do not make any restrictions. For example, teeth are provided on the first support column 2, and a gear is provided at the connection between the fixing frame 4 and the first support column 2, and the teeth are meshed with the gear, so as to realize that the fixing frame 4 is slidably provided on the first support column 2. For another example, a slide rail is provided on the first support column 2, and the fixing frame 4 is provided on the slide rail, so as to realize that the fixing frame 4 is slidably provided on the first support column 2.
[0036] Regarding how the cross plate 5 is slidably provided within the frame of the fixing frame 4 and how the tapping machine 6 is slidably provided on the cross plate 5, the embodiments of the present disclosure do not make any restrictions, and any cooperation method that can realize mutual sliding between the two structures can be applied herein.
[0037] It should be noted that the forging fixing device 301 can move towards the middle of the forging fixing table 3, so as to clamp the forging and realize the fixing of the forging. Figure 1The forging fixing device 301 shown is merely exemplary with two clamping plates, and any device that can fix and release the forging can be applied here.
[0038] By setting the forging fixing device on the forging fixing table, when the tapping machine taps the forging, the sliding of the forging can be avoided, thus ensuring the accuracy of tapping. By means of the sliding setting of the fixing frame on the first support column, the sliding setting of the cross plate on the fixing frame, and the sliding setting of the tapping machine on the cross plate, the tapping machine can be moved in three dimensions, so that the position where the tapping device can tap is flexibly adjustable, with high flexibility.
[0039] In one embodiment, as Figure 2 shown, on the basis of the tapping device for forgings shown in Figure 1 the tapping device for forgings may further include: a protective cover 7, arranged on the bench 1 and surrounding the forging fixing table 3, and one end of the protective cover 7 away from the bench 1 is open.
[0040] By setting a protective cover on the bench that can surround the forging fixing table, when the tapping device processes the forging, the splashing of debris during tapping can be effectively reduced, the difficulty and workload of cleaning the debris can be reduced, and the possibility of debris hurting people can be reduced.
[0041] It should be noted that, as shown in 2, the shape of the protective cover 7 is merely exemplary, and any protective cover that can surround the forging fixing table 3 and has an open top surface can be applied here.
[0042] In one embodiment, as Figure 3 shown, on the basis of the tapping device for forgings shown in Figure 2 the protective cover 7 is provided with a jet port 701; a groove 101 is arranged on the bench 1, and the groove 101 is located in the area between the forging fixing table 3 and the protective cover 7, and is far from the jet port 701 and close to the protective cover 7. The tapping device for forgings further includes: a jet device 8, inserted into the jet port 701 from the outside to the inside.
[0043] It should be noted that Figure 3 in 2, the jet device 8 is not completely drawn, but only the nozzle inserted into the jet port 701 is drawn.
[0044] The way of setting a jet port on the protective cover enables the debris generated during tapping to be blown to one side of the protective cover by jetting, which is beneficial to centralized cleaning of the debris and reduces the difficulty of debris cleaning. In addition, by setting a groove in the area between the forging fixing table and the protective cover, and the groove is far from the jet port and close to the protective cover, the debris blown by the jet port can enter the groove, thus making it more convenient for the staff to collect and clean the debris.
[0045] In one embodiment, as Figure 4 shown, on the basis of the tapping device for forgings as Figure 3 shown, a collection box 102 is further slidably arranged on the bench 1. The collection box 102 is arranged below the groove 101, and a communication is provided between the groove 101 and the collection box 102.
[0046] By arranging the collection box below the groove, the debris blown into the groove can fall into the collection box, facilitating the collection of the debris; by slidably arranging the collection box on the bench, it is convenient to clean the debris in the collection box.
[0047] In one embodiment, as Figure 5 shown, the tapping device for forgings further includes: a second support column 9, a photographing device 10, a control device, a first motor, a second motor, and a third motor.
[0048] The second support column 9 is arranged on the bench 1; the photographing device 10 is arranged on the second support column 9, and the range of the picture photographed by the photographing device 10 includes the forging fixing table 3; the forging fixed on the forging fixing table 3 has a tapping mark at the position where tapping is required.
[0049] The first motor is used to control the movement of the fixing frame 4 on the first support column 2, the second motor is used to control the movement of the cross plate 5 within the frame of the fixing frame 4, and the third motor is used to control the movement of the tapping machine 6 on the cross plate 5.
[0050] The control device is connected to the photographing device 10 to obtain and respectively generate control instructions for controlling the first motor, the second motor, and the third motor according to the picture photographed by the photographing device 10.
[0051] It should be noted that Figure 5 the control device, the first motor, the second motor, and the third motor are not drawn in ; for the control device, it can be arranged at any position and connected to the photographing device 10, the first motor, the second motor, and the third motor respectively through signal lines; for the positions where the first motor, the second motor, and the third motor are arranged, those of ordinary skill in the art can arbitrarily determine one or more ways of arranging the first motor, the second motor, and the third motor according to that the first motor is used to control the movement of the fixing frame 4 on the first support column 2, the second motor is used to control the movement of the cross plate 5 within the frame of the fixing frame 4, and the third motor is used to control the movement of the tapping machine 6 on the cross plate 5, so that the first motor, the second motor, and the third motor respectively control the movement of the fixing frame 4, the cross plate 5, and the tapping machine 6.
[0052] Embodiments of the present disclosure do not limit how the control device controls the first motor, the second motor, and the third motor. For example, the first motor, the second motor, and the third motor can be controlled by controlling the on / off state of the motor and the positive / negative of the input electrical signal, so as to control the movement of the fixed frame 4 on the first support column 2, the movement of the cross plate 5 within the frame of the fixed frame 4, and the movement of the tapping machine 6 on the cross plate 5.
[0053] By configuring the second support column, the photographing device, the control device, the first motor, the second motor, and the third motor, and setting tapping marks on the forging, the tapping device can automatically identify the tapping marks on the forging, so as to adjust the position of the tapping machine by controlling the first motor, the second motor, and the third motor, so that the tapping position of the tapping machine is aligned with the tapping marks on the forging. In this way, the position of the tapping machine is automatically adjusted according to the tapping marks on the forging, which is beneficial to the automation of the entire tapping process of the forging; in addition, it is easier to have a large error when manually adjusting the tapping position of the tapping machine. The method of automatically adjusting the tapping position of the tapping machine by using the photographing device, the control device, the first motor, the second motor, and the third motor is more stable, accurate, and reliable, thereby improving the yield rate of the finished product after tapping the forging.
[0054] Embodiments of the present disclosure do not limit how the control device generates control commands for controlling the first motor, the second motor, and the third motor respectively according to the images captured by the photographing device 10.
[0055] In one embodiment, the control device records the position information of the tapping machine 6; the control device generating control commands for controlling the first motor, the second motor, and the third motor respectively according to the images captured by the photographing device 10 may include: the control device determining the position information of the tapping marks on the forging according to the images captured by the photographing device 10; and generating control commands for controlling the first motor, the second motor, and the third motor respectively according to the position information of the tapping machine 6 and the position information of the tapping marks.
[0056] The position of the tapping machine 6 can be modeled in the control device. For example, a model representing the current position of the tapping machine can be established according to the range in which the tapping machine 6 can move on the cross plate 5, the range in which the cross plate 5 can move within the frame of the fixed frame 4, the range in which the fixed frame 4 can move on the first support column 2, the initial position of the tapping machine 6, and the positional relationship between the forging fixing table 3 and the first support column 2. Each time the fixed frame 4 is controlled to move on the first support column 2, and / or the cross plate 5 is controlled to move within the frame of the fixed frame 4, and / or the tapping machine 6 is controlled to move on the cross plate 5, the position of the tapping machine 6 after the movement can be determined according to the moving direction, distance, and the position of the tapping machine before the movement.
[0057] The embodiments of the present disclosure do not limit how the control device obtains the distance that the fixed frame 4 moves on the first support column 2, the distance that the cross plate 5 moves within the frame of the fixed frame 4, and the distance that the tapping machine 6 moves on the cross plate 5.
[0058] In one embodiment, the distance that the fixed frame 4 moves on the first support column 2 can be determined according to the drive electrical signal applied to the first motor, the duration of the drive electrical signal, and the speed at which the first motor drives the fixed frame 4 to move on the first support column 2 under different electrical signals. Among them, the drive electrical signal and the duration of the drive electrical signal can be directly applied by the control device. Accordingly, the control device can directly obtain the drive electrical signal and the duration of the drive electrical signal. The speed at which the first motor drives the fixed frame 4 to move on the first support column 2 under different drive electrical signals can be obtained through testing, and the test results can be stored in the control device.
[0059] In one embodiment, the control device obtains the distance that the fixed frame 4 moves on the first support column 2, the distance that the cross plate 5 moves within the frame of the fixed frame 4, and the distance that the tapping machine 6 moves on the cross plate 5 in the same way.
[0060] In another embodiment, based on the tapping device for forgings shown in Figure 5 the tapping device for forgings may further include: a first encoder, a second encoder, and a third encoder.
[0061] The first encoder is used to measure the distance that the fixed frame 4 moves on the first support column 2; the second encoder is used to measure the distance that the cross plate 5 moves within the frame of the fixed frame 4; the third encoder is used to measure the distance that the tapping machine 6 moves on the cross plate 5.
[0062] The control device is respectively connected to the first encoder, the second encoder, and the third encoder to obtain the displacement signals measured by the first encoder, the second encoder, and the third encoder.
[0063] Among them, the displacement signal generated by the first encoder can represent the distance and direction that the fixed frame 4 moves on the first support column 2, the displacement signal generated by the second encoder can represent the distance and direction that the cross plate 5 moves within the frame of the fixed frame 4, and the displacement signal generated by the third encoder can represent the distance and direction that the tapping machine 6 moves on the cross plate 5.
[0064] The control device can determine the final distance and direction that the tapping machine 6 moves according to the displacement signals measured by the first encoder, the second encoder, and the third encoder, and then determine the position of the tapping machine 6 after movement in combination with the position of the tapping machine 6 before movement.
[0065] In one embodiment, the control device records the position information of the tapping machine 6 (the position information before movement). The control instructions for controlling the first motor, the second motor, and the third motor respectively generated by the control device according to the image captured by the imaging device 10 include: the control device determines the position information of the tapping mark on the forging according to the image captured by the imaging device 10; and generates the control instructions for controlling the first motor, the second motor, and the third motor respectively according to the position information of the tapping machine 6 and the position information of the tapping mark.
[0066] In one embodiment, the control device records the position information of the forging fixing table 3; the control device determining the position information of the tapping mark on the forging according to the image captured by the imaging device 10 may include: the control device identifies the tapping mark from the image captured by the imaging device 10; determines the positional relationship between the tapping mark and the forging fixing table 3; and calculates the position information of the tapping mark according to the position information of the forging fixing table 3 and the positional relationship.
[0067] Wherein, the forging fixing table 3 is fixed on the bench 1, and the position information (actual position information) of the forging fixing table 3 is fixed and unchanged.
[0068] The manner in which the control device identifies the tapping mark from the image captured by the imaging device 10 may include: applying a network model for target recognition (for example, R-CNN (Regions with CNN features), Fast R-CNN, etc.) in the control device to identify the tapping mark and the position of the tapping mark in the image.
[0069] Regarding how to determine the positional relationship between the tapping mark and the forging fixing table 3, the embodiments of the present disclosure do not make any limitations. For example, according to the height of the imaging device 10 on the second support column 9, the shooting angle of the imaging device 10, and the range of the captured image, the position of the forging fixing table 3 in the image can be directly determined. Since the forging fixing table 3 is fixed and unchanged, the position of the forging fixing table 3 in the image is fixed and unchanged when the position of the imaging device 10 remains unchanged. The position information of the forging fixing table 3 in the image can be pre-stored in the control device. After that, according to the position information of the forging fixing table 3 and the tapping mark in the image respectively, the positional relationship between the tapping mark and the forging fixing table 3 can be determined.
[0070] Then, according to the position information (actual position information) of the forging fixing table 3 and the positional relationship (the positional relationship between the forging fixing table 3 and the tapping mark), the position information of the tapping mark is calculated.
[0071] After determining the position information of the tapping mark, the control device generates control instructions for controlling the first motor, the second motor, and the third motor respectively according to the position information of the tapping machine 6 and the position information of the tapping mark, so as to control the tapping machine 6 to move to a position matching the tapping mark, thereby tapping the forging.
[0072] In one embodiment, the photographing device 10 is slidably arranged on the second support column 9; the tapping device for the forging further includes: a fourth motor for controlling the movement of the photographing device 10 on the second support column 9; the control device is further configured to control the fourth motor according to a predetermined control strategy.
[0073] Regarding what specific control strategy the predetermined control strategy is, the embodiments of the present disclosure do not limit it. For example, when the tapping mark cannot be recognized in the picture taken at the current position, a control instruction is sent to the fourth motor to control the photographing device 10 to move a certain distance on the second support column 9, and then take pictures again until the tapping mark is recognized in the taken picture, or it is determined that the tapping mark cannot be recognized because the photographing device 10 cannot move further.
[0074] By slidably arranging the photographing device on the second support column and controlling the movement of the photographing device through the control device, in the case of different forging shapes and the tapping machine blocking the tapping mark, the picture of the tapping mark on the forging can be moved, so as to control the alignment of the tapping position of the tapping machine with the position where the tapping mark is located.
[0075] In one embodiment, the control device is further configured to determine whether the positional relationship between the tapping mark and the tapping machine 6 satisfies the tapping start condition according to the picture taken by the photographing device 10 after the first motor, the second motor, and the third motor complete the control instructions.
[0076] When the positional relationship between the tapping mark and the tapping machine 6 does not satisfy the tapping start condition, the control device regenerates the control instructions for controlling the first motor, the second motor, and the third motor respectively according to the positional relationship between the tapping mark and the tapping machine 6.
[0077] Regarding what specific conditions the tapping start condition is, the embodiments of the present disclosure do not limit it. For example, the tapping start condition is that the difference in the three-dimensional coordinates in the vertical direction between the three-dimensional coordinates of the representative point of the tapping machine 6 and the three-dimensional coordinates of the center position of the tapping mark is a predetermined value, and the coordinates in the horizontal and vertical directions are the same.
[0078] After controlling the tapping machine to complete the movement, detecting again whether the position between the tapping machine and the tapping mark can start tapping, and continuing to adjust the position of the tapping machine when the position cannot start tapping can further ensure that the tapping position of the tapping machine matches the tapping mark, guarantee the accuracy of the tapping position, and improve the yield rate of the finished product.
[0079] Other embodiments of the present disclosure will be readily apparent to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. The present disclosure is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include known common general knowledge or conventional technical means in the technical field not disclosed in the present disclosure.
