[0002] Pressing steel balls into the process holes of castings is a common post-casting treatment technology, and its functions mainly include improving the sealing performance and protecting the cleanliness and purity inside the castings. Among them, by pressing steel balls for plugging, it can effectively prevent the leakage of liquid or gas inside the castings and ensure the sealing performance of the castings in a high-pressure environment. In addition, by pressing steel balls for plugging, it can effectively prevent external substances such as impurities and dust from entering the inside of the castings and protect the cleanliness and purity inside the castings.

[0003] With the development of automation technology, automatic steel ball pressing technology has emerged. When press-fitting steel balls with interference into the process holes of workpieces, it is necessary to ensure firm press-fitting and achieve a sealing effect. Therefore, in order to ensure the firm sealing performance of the steel balls press-fitted into the process holes of the workpieces, it is necessary to monitor the steel ball pressing process to ensure that the steel ball pressing effect meets the requirements.

[0037] Refer to Figure 1 , Figure 1 which shows a schematic structural diagram of an automatic steel ball pressing and sealing device in an embodiment of the present application. The automatic steel ball pressing and sealing device in an embodiment of the present application includes a frame 100, a conveying assembly 200, a pressing assembly 300 and a monitoring mechanism assembly.

[0038] Among them, as shown in combination with Figure 1 and Figure 3 , the conveying assembly 200 includes a bushing 210 and a first driving mechanism 220. The bushing 210 is provided with an inlet structure 211 and a conveying channel 212. The inlet structure 211 is used to feed steel balls into the conveying channel 212. The first driving mechanism 220 is disposed on the frame 100, and the first driving mechanism 220 is used to drive the bushing 210 to move to a first preset position. The pressing assembly 300 includes a pressing rod 310 and a second driving mechanism 320. The pressing rod 310 passes through the bushing 210. The second driving mechanism 320 is disposed on the frame 100, and the second driving mechanism 320 is used to drive the pressing rod 310 to reciprocate along the axial direction of the conveying channel 212 in the conveying channel 212, so that the steel balls located in the conveying channel 212 can be continuously pressed into the process hole of the workpiece. The monitoring mechanism assembly includes a displacement monitoring mechanism 410, a pressure monitoring mechanism 420 and a data processing center (not shown). The displacement monitoring mechanism 410 is used to monitor the movement amount of the pressing rod 310, the pressure monitoring mechanism 420 is used to monitor the axial pressure received by the pressing rod 310 during the movement process, and the data processing center is used to output a pressure-displacement curve.

[0039] Specifically, when applying the above steel ball automatic pressing and sealing device, the pressing operation can be first performed on the steel balls and workpieces that meet the design requirements, and then the first preset position and the movement amount of the pressing rod 310 during a single steel ball pressing process can be determined. Under this setting, a standard pressure-displacement curve can be obtained. Then, a standard pressure-displacement interval can be formulated based on this pressure-displacement curve. Finally, while keeping the first preset position and the movement amount of the pressing rod 310 during a single steel ball pressing process unchanged, a batch of steel balls and workpieces are pressed. If the pressure-displacement curve output by the data processing center falls within the above standard pressure-displacement interval, it means that the steel balls and workpieces meet the design requirements. If the pressure-displacement curve output by the data processing center does not fall within the above standard pressure-displacement interval, it means that the steel balls and workpieces do not meet the design requirements. In this way, the automatic pressing of steel balls and the detection of the pressing effect are realized, and the operation is simple and efficient.

[0040] It should be noted that the above first preset position can be designed according to the relative positions of the specific workpiece and the bushing 210. Preferably, when the bushing 210 moves to the first preset position, the bushing 210 is just aligned with the process hole of the workpiece, so that the precise pressing of the steel balls can be realized.

[0041] The above steel ball automatic pressing and sealing device organically combines the frame 100, the conveying component 200, the pressing component 300 and the monitoring mechanism component. In this way, the automatic pressing of steel balls and the detection of the pressing effect can be realized simultaneously, which helps to improve the structural integration of the steel ball automatic pressing and sealing device and reduce the defective rate. In addition, the first driving mechanism 220 and the second driving mechanism 320 respectively control the movement of the bushing 210 and the pressing rod 310, so as to realize the independent control of the position of the bushing 210 and the pressing of the pressing rod 310, which helps to improve the control flexibility of the bushing 210 and the pressing rod 310.

[0042] Refer to Figure 4 and Figure 5 , Figure 4 is Figure 1 a partial structural schematic diagram of the steel ball automatic pressing and sealing device shown, Figure 5 is Figure 4 an exploded view of the structure shown.

[0043] In some embodiments, the pressing component 300 further includes a connector 330. The pressing rod 310 includes a first ejector rod 311 and a second ejector rod 312. One end of the first ejector rod 311 is detachably connected to one end of the second ejector rod 312 through the connector 330, so as to improve the simplicity of structure disassembly and assembly. Among them, the second ejector rod 312 is used to press the steel balls into the process hole of the workpiece in the conveying channel 212.

[0044] Specifically, the first ejector rod 311 and the second ejector rod 312 are located on the same axis, so as to ensure the accuracy of pressure conduction of the first ejector rod 311 and the second ejector rod 312. In addition, the first ejector rod 311 and the second ejector rod 312 are detachably connected, so that the first ejector rod 311 and the second ejector rod 312 of different sizes can be disassembled and assembled according to different steel ball and workpiece assembly conditions, which helps to improve the applicability of the automatic pressing of steel balls into the sealing device.

[0045] Continue to refer to Figures 1 to 3 , in some embodiments, the second driving mechanism 320 includes a power mechanism 321 and a mounting block 322, and the power mechanism 321 is used to drive the mounting block 322 to reciprocate. The pressure rod 310 is arranged on the mounting block 322, and the connecting head 330 includes a fixed joint 331 and a movable joint 332. Among them, the fixed joint 331 is fixed to the mounting block 322, the first ejector rod 311 and the pressure monitoring mechanism 420 are received in the fixed joint 331, and the first ejector rod 311 can press the pressure monitoring mechanism 420 against the mounting block 322. The movable joint 332 is connected to the second ejector rod 312, and the movable joint 332 is movably connected to the fixed joint 331, so that the second ejector rod 312 presses the first ejector rod 311 and changes the pressure of the first ejector rod 311 pressing the pressure monitoring mechanism 420.

[0046] Specifically, the connection method between the movable joint 332 and the fixed joint 331 can be snap connection, threaded connection, etc. By changing the insertion depth of the movable joint 332 in the fixed joint 331, the pressure of the second ejector rod 312 pressing the first ejector rod 311 can be changed, and then the initial pressure value of the pressure monitoring mechanism 420 can be changed. By observing the above initial pressure value, the connection strength between the first ejector rod 311 and the second ejector rod 312 can be judged. When it is observed that the initial pressure value is abnormally large or small, the connection strength can be strengthened by adjusting the insertion depth of the movable joint 332 and the fixed joint 331, which helps to prevent the first ejector rod 311 and the second ejector rod 312 from being not tightly connected, resulting in inaccurate data reported by the pressure monitoring mechanism 420.

[0047] Combined with Figure 5 and Figure 6As shown, in some embodiments, one end of the movable joint 332 is provided with an adjusting conical surface 3321, the fixed joint 331 is provided with an adjusting member 3311 and an adjusting hole 3312 is formed. The adjusting member 3311 is inserted into the adjusting hole 3312. When the end of the movable joint 332 with the adjusting conical surface 3321 is inserted into the fixed joint 331, the adjusting member 3311 can abut against the adjusting conical surface 3321, and the adjusting member 3311 can adjust its insertion depth in the adjusting hole 3312 to adjust the insertion depth of the movable joint 332. Understandably, the adjusting member 3311 can be arbitrarily adjusted and locked in the adjusting hole 3312 to maintain the insertion depth of the movable joint 332 in the fixed joint 331.

[0048] Specifically, when it is necessary to adjust the connection strength between the first ejector rod 311 and the second ejector rod 312, only the insertion depth of the adjusting member 3311 in the adjusting hole 3312 needs to be adjusted. The adjusting conical surface 3321 of the movable joint 332 will move relative to the adjusting member 3311 under the pressing and pushing action of the adjusting member 3311, so that the movable joint 332 approaches or moves away from the fixed joint 331. Furthermore, the movable joint 332 will drive the second ejector rod 312 to move in the direction of approaching or moving away from the first ejector rod 311, so that the first ejector rod 311 changes the pressure on the pressure monitoring mechanism 420 under the pressing action of the second ejector rod 312. By observing the data of the pressure monitoring mechanism 420 in this way, the adjustment of the tight connection between the first ejector rod 311 and the second ejector rod 312 can be completed.

[0049] Continue to refer to Figure 4 and Figure 5 , in some embodiments, a flange 3121 is provided near one end of the second ejector rod 312 close to the movable joint 332, and a clamping groove 3322 is formed at one end of the movable joint 332 away from the adjusting conical surface 3321. The flange 3121 can be clamped in the clamping groove 3322, so that the second ejector rod 312 can be quickly disassembled and assembled.

[0050] Specifically, in this embodiment, since the second ejector rod 312 needs to be disassembled and assembled, there will be a certain floating amount when the flange 3121 is clamped in the clamping groove 3322. Therefore, in cooperation with the movable connection between the movable joint 332 and the fixed joint 331, when the movable joint 332 and the fixed joint 331 are in a mutually locked state, the flange 3121 can tightly fit against the groove wall of the clamping groove 3322. In addition, the pressure monitoring mechanism 420 can display the initial pressure value of the pressure monitoring mechanism 420 being pressed by the first ejector rod 311 after the first ejector rod 311 and the second ejector rod 312 are assembled with each other, so as to judge whether the floating amount of the flange 3121 in the clamping groove 3322 is eliminated, to prevent the problem of loosening of the connection between the first ejector rod 311 and the second ejector rod 312 and improve the structural reliability of the steel ball automatic pressing and sealing device.

[0051] Combined Figure 1 As shown, in some embodiments, the pressing component 300 further includes a first limiting block 340. The first limiting block 340 is disposed on the mounting block 322. The conveying component 200 further includes a moving base 230, and the bushing 210 is disposed on the moving base 230. When the mounting block 322 moves close to the moving base 230, the first limiting block 340 can abut against the moving base 230, so that the pressing rod 310 can be limited during movement, which helps to prevent the movement interference between the first driving mechanism 220 and the second driving mechanism 320 and improve the working reliability.

[0052] In addition, when the mounting block 322 moves close to the moving base 230, the first limiting block 340 can abut against the moving base 230, so that the pressing rod 310 can press the steel ball into the process hole of the workpiece with a fixed displacement amount, which helps to improve the movement accuracy of the pressing rod 310 and further improve the accuracy of the pressure-displacement curve output by the data processing center. Further, in some embodiments, the first limiting block 340 protrudes from the mounting block 322, and the protruding length of the first limiting block 340 protruding from the mounting block 322 is adjustable, so as to be able to change the pressing amount of the pressing rod 310 on the steel ball to meet the assembly requirements of steel balls and workpieces of different specifications.

[0053] Combined Figure 1 As shown, in some embodiments, the number of the first limiting blocks 340 is two, which are respectively disposed on both sides of the mounting block 322, so as to help improve the structural reliability.

[0054] Combined Figure 1 and Figure 3 As shown, in some embodiments, the moving base 230 is connected to the first driving mechanism 220, and the frame 100 is provided with a second limiting block 110. When the second driving mechanism 320 drives the moving base 230 to move and abuts against the second limiting block 110, the bushing 210 is in a first preset position, so that the bushing 210 aligns with the process hole of the workpiece at the first preset position. Specifically, the above-mentioned first preset position is determined according to the position of workpiece loading, the length of the pressing rod 310, and the contact and pressing situation between the bushing 210 and the workpiece. Preferably, when the bushing 210 is in the first preset position, the bushing 210 is in contact with the workpiece and can provide a slight extrusion, which helps to improve the pressing effect of the pressing rod 310 on the steel ball.

[0055] Combined Figure 1 and Figure 3As shown, in some embodiments, the monitoring mechanism assembly further includes an in-position detection mechanism 430 and a protrusion mechanism 440. The protrusion mechanism 440 is telescopically disposed in the bushing 210 and is used to block or conduct the conveying channel 212. The in-position detection mechanism 430 is disposed at the position of the inlet structure 211 and is used to monitor the number of steel balls conveyed. When it is detected that there is a lack of steel balls in the conveying channel 212, a signal can be sent in time so that the steel balls can be automatically pressed into the sealing device and the steel balls can be sent into the conveying channel 212 in time, so as to improve the automation degree of the steel ball automatic pressing into the sealing device and improve the operation efficiency.

[0056] Specifically, the in-position detection mechanism 430 can be an inductor and is used to perform in-position induction on the steel balls in the conveying channel 212 from both sides of the conveying channel 212. When the steel balls are pushed out by the pressing rod 310 and leave the induction position, the in-position detection mechanism 430 can send a signal in time to supplement the next steel ball, so as to realize the automatic continuous pressing operation of the steel balls. The protrusion mechanism 440 can be a blocking block or a blocking rod. The above-mentioned protrusion mechanism 440 being telescopically disposed in the bushing 210 means that the protrusion mechanism 440 can be retracted into the shrinkage hole corresponding to the bushing 210, or can protrude from the inner wall surface of the bushing 210 and be in the conveying channel 212, and can withstand a certain pressure to maintain the protruding state, and thus can abut and block the movement of the steel balls. In some embodiments, the protrusion mechanism 440 includes a stopper and an elastic member. When the elastic member is not squeezed, the stopper is used to block the conveying channel 212; when the pressing rod 310 pushes the steel balls, the steel balls squeeze the stopper and the elastic member, and at this time the conveying channel 212 is conducted. The stopper can be reset under the elastic action of the elastic member and block the conveying channel 212 again. The above settings enable the steel ball automatic pressing into the sealing device to automatically press the steel balls into the process holes of the workpiece one by one, which helps to improve the pressing efficiency.

[0057] Combined Figure 1 and Figure 2 As shown, in some embodiments, the displacement monitoring mechanism 410 includes a displacement sensor 411, a target block 412 and a home position sensor 413. The target block 412 is connected to the second driving mechanism 320. The displacement sensor 411 is connected to the bushing 210. The home position sensor 413 is fixedly disposed on the frame 100. The displacement sensor 411 is used to monitor the relative displacement amount between the target block 412 and the displacement sensor 411. The home position sensor 413 is used to monitor the offset amount of the target block 412 relative to the home position sensor 413.

[0058] Specifically, the displacement sensor 411 and the target block 412 are relatively spaced apart in the length direction of the pressure rod 310, so that the target block 412 can move closer to or away from the displacement sensor 411 driven by the second driving mechanism 320, making the relative movement amount of the target block 412 relative to the displacement sensor 411 consistent with the movement amount of the pressure rod 310, thereby improving the monitoring accuracy of the displacement sensor 411 for the movement amount of the pressure rod 310. Further, the displacement monitoring mechanism 410 can also be provided with a home position sensor 413, and the home position sensor 413 is used to monitor the offset amount of the target block 412 to achieve dual monitoring with the displacement sensor 411, which helps to improve the monitoring accuracy. In addition, the home position sensor 413 can also be used to return the pressure rod 310 to the initial position after each operation, so that the movement amount of the pressure rod 310 in each steel ball pressing process is consistent, which helps to improve the accuracy of the pressure-displacement curve output by the data processing center.

The workpiece positioning device is used to move the workpiece to be assembled to the first preset position, and the steel ball conveying device is used to send steel balls into the inlet structure 211 of the automatic steel ball pressing and sealing device.

[0061] For the above-mentioned automatic steel ball pressing and sealing system, through the organic combination of the frame 100, the conveying assembly 200, the pressing assembly 300 and the monitoring mechanism assembly of the automatic steel ball pressing and sealing device, the automatic pressing of steel balls and the detection of the pressing effect can be achieved simultaneously, which helps to improve the structural integration degree of the automatic pressing system and reduce the defective product rate. In addition, by controlling the movement of the bushing 210 and the pressure rod 310 respectively through the first driving mechanism 220 and the second driving mechanism 320 of the automatic steel ball pressing and sealing device, the independent control of the position of the bushing 210 and the pressing of the pressure rod 310 is realized, which helps to improve the control flexibility of the bushing 210 and the pressure rod 310. Further, the automatic steel ball pressing and sealing system is also provided with a workpiece positioning device (not shown) and a steel ball conveying device (not shown), so that the automatic alignment of the workpiece and the bushing 210 and the automatic conveying of steel balls can be realized, which helps to improve the automation degree of the automatic steel ball pressing and sealing system and thus improve the operation efficiency.
