[0002] During the manufacturing process of the valve structure, the valve core needs to be installed into the mounting hole of the oil circuit board. However, in the actual production process, the valve core is usually installed into the mounting hole of the oil circuit board manually. This manufacturing method leads to low production efficiency and high cost. On the other hand, the inner diameter of the mounting hole is usually only about 1.05 to 1.3 times the outer diameter of the valve core. Such matching accuracy brings difficulties to the assembly of the valve core. Summary of the invention

[0039] like Figure 1 and Figure 2 As shown, the embodiment of the present application discloses a valve core assembly tool, including a turntable 1, a clamping mechanism 2, a pressing mechanism 3 and a blanking mechanism 4;

[0040] The turntable 1 is rotatably arranged, wherein a workbench 5 is arranged in the middle of the turntable 1, the turntable 1 and the workbench 5 are arranged coaxially, and the turntable 1 can rotate horizontally around the center of the workbench 5. The embodiment of the present application also includes a device for driving the turntable 1 to rotate horizontally, and the device can refer to the prior art.

[0041] like Figure 2 As shown, there are multiple clamping mechanisms 2. Six clamping mechanisms 2 are illustrated in the embodiment of the present application. Multiple clamping mechanisms 2 are arranged at equal intervals at the edge of the turntable 1 along the horizontal circumference of the turntable 1, and the oil circuit plate 7 is installed through the clamping mechanisms 2.

[0042] like Figure 3 As shown, the oil circuit board 7 is provided with a mounting hole 71 and a positioning hole 72 , and the mounting hole 71 is used for mounting the valve core.

[0043] like Figure 4 and Figure 5 As shown, the clamping mechanism 2 includes a vertical plate 21, a positioning unit 22 and a clamping unit 23. The vertical plate 21 is vertically fixed at the edge of the turntable 1; the positioning unit 22 includes a top pin 221 and at least two positioning pins 222, one end of the top pin 221 is arranged on the side of the vertical plate 21 away from the pressing mechanism 3, and the end face of the other end of the top pin 221 can be against the side wall surface of the oil circuit plate 7; the positioning pin 222 is arranged on the side of the vertical plate 21 away from the pressing mechanism 3, and the oil circuit plate 7 is provided with positioning holes 72 corresponding to the positioning pins 222 one by one, and at least part of the positioning pins 222 can be inserted into the positioning holes 72 to realize the positioning of the oil circuit plate 7; the clamping unit 23 is arranged on the vertical plate 21, and is used to press the oil circuit plate 7 onto the top pin 221.

[0044] In the embodiment of the present application, at least two positioning pins 222 are provided to stably position the oil circuit plate 7 on the vertical plate 21 to prevent the oil circuit plate 7 from moving during the process of pressing the valve core. At the same time, a clamping unit 23 is also designed to further stabilize the oil circuit plate 7.

[0045] like Figure 5As shown, the pressing unit 23 includes a first hinge block 231, a pressure block 232, a second hinge block 233, a slide bar 234, a driving plate 235 and a second elastic member 236; one end of the first hinge block 231 is fixedly arranged on the side of the vertical plate 21 away from the pressing mechanism 3; one end of the pressure block 232 is hinged to the other end of the first hinge block 231, and the pressure block 232 is used to press the oil circuit board 7 onto the top pin 221; one end of the second hinge block 233 is hinged to the middle position of the pressure block 232, and the other end of the second hinge block 233 is hinged to the end of the slide bar 234; the slide bar 234 slides along the radial direction (i.e., horizontal direction) of the turntable 1 and penetrates the vertical plate 21. When the slide bar 234 slides, it can The second elastic member 236 is configured as a spring, and the second elastic member 236 is coaxially sleeved on the outer periphery of the slide bar 234 (the extension and contraction direction of the second elastic member 236 is consistent with the axial direction of the slide bar 234), and the second elastic member 236 is against between the drive plate 235 and the vertical plate 21. In the absence of external force, the second elastic member 236 has an elastic force to push the drive plate 235 away from the vertical plate 21, so that the drive plate 235 can drive the slide bar 234 to slide, thereby driving the pressure block 232 to press the oil circuit plate 7.

[0046] In some preferred embodiments, Figure 5 As shown, an elastic pad 237 (such as a rubber pad, a sponge pad, etc.) is provided on the pressing block 232, and the pressing block 232 abuts against the oil circuit board 7 through the elastic pad 237. The design of the elastic pad 237 can avoid rigid contact between the pressing block 232 and the oil circuit board 7, and avoid excessive pressure on the oil circuit board 7 to cause structural damage.

[0047] Please refer again Figure 2 The assembly tool of the embodiment of the present application further includes a telescopic driving member 6, which is arranged on an external structure. In the embodiment of the present application, the external structure refers to the workbench 5 in the middle of the turntable 1. The telescopic driving member 6 is, for example, an electric cylinder, a telescopic push rod, etc. Along the radial direction of the turntable 1, the telescopic end of the telescopic driving member 6 can abut against the driving plate 235 of any clamping mechanism 2, and the telescopic direction of the telescopic driving member 6 is configured to be the radial direction of the turntable 1.

[0048] The function of the telescopic driving member 6 is to drive the pressure block 232 to loosen the oil circuit board 7. Its specific working principle is: when the telescopic driving member 6 is extended, the telescopic end of the telescopic driving member 6 can be against the driving plate 235 of a clamping mechanism 2. As the telescopic driving member 6 continues to extend, the driving plate 235 is pushed and gradually approaches the vertical plate 21. In this process, the second elastic member 236 is compressed. Since the driving plate 235 is fixedly connected to the sliding rod 234, the sliding rod 234 is also pushed, and the pressure block 232 hinged at the end position of the sliding rod 234 also immediately loosens the oil circuit board 7. When the telescopic driving member 6 retracts, the second elastic member 236 can be reset instantly, and the pressure block 232 will press the new oil circuit board 7 again.

[0049] In the embodiment of the present application, the telescopic driving member 6 can drive the clamping mechanism 2 to loosen the oil circuit plate 7, so as to facilitate the loading and unloading of the oil circuit plate 7. At the same time, after the telescopic driving member 6 withdraws its force, the clamping mechanism 2 can automatically resume the pressure on the oil circuit plate 7.

[0050] like Figure 6 As shown, the pressing mechanism 3 is used to press the valve core into the mounting hole 71, and the pressing mechanism 3 includes a first bracket 31, a first slide rail 32, a first mounting plate 33, a second slide rail 34, a second mounting plate 35, a mounting seat 36, a pressing head 37 and a first elastic member 38;

[0051] like Figure 6 and Figure 7 As shown, the first bracket 31 is arranged on the workbench 5, the first slide rail 32 is horizontally arranged at the upper end of the first bracket 31, the sliding direction of the first slide rail 32 is configured as the radial direction of the turntable 1, the first mounting plate 33 is arranged on the first slide rail 32, and the first slide rail 32 can drive the first mounting plate 33 to slide in the sliding direction of the first slide rail 32; the second slide rail 34 is arranged on the first mounting plate 33, and the sliding direction of the second slide rail 34 is configured as the height direction; the second mounting plate 35 is arranged on the second slide rail 34, and the second slide rail 34 can drive the second mounting plate 35 to slide in the height direction The mounting seat 36 is fixedly arranged on the second mounting plate 35, and the mounting seat 36 is provided with a vertically penetrating sliding hole. The pressing head 37 penetrates the sliding hole along the height direction, and the pressing head 37 can slide in the height direction relative to the inner wall of the sliding hole. The outer periphery of the pressing head 37 is coaxially provided with a spring abutment 371, and the spring abutment 371 is located below the mounting seat 36; the first elastic member 38 is configured as a spring, and the first elastic member 38 is coaxially sleeved on the outer periphery of the pressing head 37, and the upper and lower ends of the first elastic member 38 respectively abut the lower surface of the mounting seat 36 and the spring abutment 371.

[0052] The first slide rail 32 and the second slide rail 34 can refer to the slide rail structure in the prior art. The function of the first slide rail 32 is to drive the first mounting plate 33 and the structure arranged on the first mounting plate 33 to move horizontally, and to make way for the corresponding working position to avoid interfering with other structures. When the press-fitting operation is required, the first slide rail 32 can drive the pressure head 37 to move to the top of the mounting hole 71 of the oil circuit board 7, so that the pressure head 37 and the mounting hole 71 are in a coaxial position. The second slide rail 34 is used to drive the pressure head 37 to press down or lift up.

[0053] like Figure 8 As shown, in some preferred solutions, in order to determine whether the valve core is pressed into place, the pressing mechanism 3 of the embodiment of the present application also includes a displacement sensor 39, which is arranged on the second mounting plate 35. The pull rod 391 of the displacement sensor 39 is connected to the top of the pressure head 37, and the axial direction of the pull rod 391 is consistent with the axial direction of the pressure head 37. The working principle of the displacement sensor 39 is: when the pressure head 37 is pressed into place, the pressure head 37 cannot continue to move downward. At this time, the pressure head 37 and the pull rod 391 of the displacement sensor 39 are against each other. With the continuous driving of the second slide rail 34, the length of the pull rod 391 is gradually shortened, and the displacement sensor 39 receives a signal and sends it to the external system, and the external system then drives the second slide rail 34 to drive the pressure head 37 to lift up. It should be noted that before the pressure head 37 presses the valve core into place, the pressure head 37 will also drive the pull rod 391 of the displacement sensor 39 to contract or extend a certain amount during the pressing process, but this displacement is relatively small and can be filtered out by denoising or setting the response threshold of the displacement sensor 39 to avoid the displacement giving an erroneous signal to the second slide rail 34, thereby lifting the pressure head 37 before it is pressed into place.

[0054] The blanking mechanism 4 and the pressing mechanism 3 are arranged opposite to each other in the sliding direction of the first slide rail 32, and there is a target clamping mechanism 2a arranged between the blanking mechanism 4 and the pressing mechanism 3, wherein there are multiple clamping mechanisms 2, and multiple clamping mechanisms 2 can rotate with the turntable 1. In the embodiment of the present application, a clamping mechanism 2 rotated between the blanking mechanism 4 and the pressing mechanism 3 is defined as the target clamping mechanism 2a (such as Figure 1 shown).

[0055] like Figures 9 to 13As shown, the blanking mechanism 4 includes a second bracket 41, a third slide rail 42, a third mounting plate 43 and a vibration blanking unit; the second bracket 41 is arranged on one side of the target clamping mechanism 2a along the sliding direction of the first slide rail 32, wherein the second bracket 41 and the first bracket 31 of the pressing mechanism 3 are arranged correspondingly in the sliding direction of the first slide rail 32; the third slide rail 42 is arranged on the second bracket 41, the sliding direction of the third slide rail 42 is configured as the height direction, the third mounting plate 43 is arranged on the third slide rail 42, and the third slide rail 42 can drive the third mounting plate 43 to slide in the height direction (the third slide rail 42 can refer to the prior art);

[0056] The vibration blanking unit includes a fourth mounting plate 44, a vibration ring 45, a guide cylinder 46 and a vibration generating module 47;

[0057] like Fig.11 As shown, the fourth mounting plate 44 is horizontally connected to the third mounting plate 43, and the fourth mounting plate 44 is provided with a matching through hole 441 in the vertical direction, and an oil circuit board 7 is installed on the target clamping mechanism 2a, and the mounting hole 71 on the oil circuit board 7 is coaxially corresponding to the matching through hole 441;

[0058] like Fig.12 As shown, the vibration ring 45 is arranged in the matching through hole 441, and the outer periphery of the vibration ring 45 is clearance-matched with the matching through hole 441 (for example, the outer diameter of the vibration ring 45 is 0.9 to 0.98 times the inner diameter of the matching through hole 441); the guide cylinder 46 is coaxially connected to the vibration ring 45, and the vibration generating module 47 is connected to the vibration ring 45. When the vibration generating module 47 generates vibration, the vibration ring 45 immediately vibrates horizontally in the matching through hole 441, and the guide cylinder 46 arranged in the vibration ring 45 also vibrates accordingly. Among them, the guide cylinder 46 is coaxial with the mounting hole 71 on the oil circuit board 7.

[0059] When the valve core needs to be pressed, the third slide rail 42 drives the vibration blanking unit to descend in height. When the guide cylinder 46 descends to a certain height, the external manipulator places the valve core into the guide cylinder 46, and then the pressure head 37 presses the valve core downward. Since the pressure head 37 and the mounting seat 36 can slide relative to each other, and a first elastic member 38 is provided between the pressure head 37 and the mounting seat 36, there is elastic contact between the pressure head 37 and the valve core, that is, the first elastic member 38 gives the valve core an elastic force to press it downward. During the pressing process, the vibration generating module 47 vibrates, and the guide cylinder 46 immediately vibrates to simulate the shaking of the valve core by hand, so that the valve core can be aligning to be coaxial with the mounting hole 71 during the falling process, so as to facilitate the pressing of the pressure head 37.

[0060] Here we need to explain the principle: First, in the prior art, the inner diameter of the mounting hole 71 on the oil circuit board 7 is generally 1.05 to 1.3 times the outer diameter of the valve core. Therefore, if the vibration generating module 47 is not designed, the valve core cannot be smoothly pressed into place by relying solely on the pressure of the pressure head 37, because the valve core may not be in a vertical state in the mounting hole 71, and the posture of the valve core may be inclined. In this case, when the pressure head 37 is pressed downward, the valve core will only be tilted and stuck in the mounting hole 71. To put it another way, even if the valve core can be pressed If the valve core is not fully installed, the press-fitting efficiency is also very low; 2. In the embodiment of the present application, the vibration generating module 47 and the elastic contact pressure head 37 can complement each other. The vibration generating module 47 can drive the valve core to vibrate to increase the falling rate of the valve core. At the same time, the elastic contact pressure head 37 can give the valve core space to adjust its posture. On the contrary, if a rigid contact pressure head 37 is used, it is useless even if the guide cylinder 46 and the valve core can vibrate, because the valve core has been tightened by the pressure head 37, and the valve core has no space to adjust its posture. Here we explain the rigid contact pressure head 37 and the elastic contact pressure head 37. The rigid contact pressure head 37 refers to the pressure head 37 that cannot float up and down during the descent process, while the elastic contact pressure head 37 refers to the elastic force given to the pressure head 37 downward by the first elastic member 38. At the same time, the pressure head 37 can overcome the elastic force of the first elastic member 38 and float up and down during the descent process.

[0061] like Fig.12 As shown, an annular mounting surface 451 is provided on the inner periphery of the vibration ring 45, a first ring portion 46a is provided on the outer periphery of the guide cylinder 46, the lower surface of the first ring portion 46a is fitted and mounted on the annular mounting surface 451, and a clamping ring 48 is connected to the upper surface of the vibration ring 45, the lower surface of the clamping ring 48 is against the upper surface of the first ring portion 46a. In the embodiment of the present application, the guide cylinder 46 is pressed onto the vibration ring 45 by the clamping ring 48, so as to ensure that the vibration generated by the vibration generating module 47 can be effectively transmitted to the guide cylinder 46, and then the guide cylinder 46 gives the valve core a shaking force to correct its posture.

[0062] like Fig.12 and Fig.13 As shown, the guide cylinder 46 includes a first section 461 and a second section 462 along its axial direction; the first section 461 is coaxially arranged in the vibration ring 45; the second section 462 is located below the vibration ring 45 and the fourth mounting plate 44, that is, the second section 462 protrudes from below the fourth mounting plate 44, and the outer diameter of the second section 462 is smaller than the inner diameter of the mounting hole 71 on the oil circuit plate 7.

[0063] In the embodiment of the present application, when the third slide rail 42 drives the guide cylinder 46 to descend, since the outer diameter of the second section 462 of the guide cylinder 46 is smaller than the inner diameter of the mounting hole 71, the second section 462 of the guide cylinder 46 can be at least partially inserted into the mounting hole 71. In this way, a complete falling channel can be created for the valve core, and it is also convenient to install the valve core in place.

[0064] In order to adapt to different working conditions, the guide tube 46 has two different forms. One is that the guide tube 46 includes the first section 461 and the second section 462. Fig.14 and Fig.15 As shown, another form is that the guide cylinder 46 only includes the first section 461, and the lower end surface of the first section 461 is flush with the lower surface of the fourth mounting plate 44, as shown in FIG. Fig.14 and Fig.15 shown.

[0065] Please refer again Fig.12 In some preferred embodiments, the first ring portion 46a is coaxially arranged on the outer periphery of the first section 461.

[0066] Please refer again Fig.12 In some preferred embodiments, the upper end opening of the first section 461 is configured as a tapered inlet, which facilitates the introduction of the valve core into the guide tube 46.

[0067] Please refer again Fig.13 In some embodiments, the vibration generating module 47 includes a connecting portion 471 and a vibrator 472. One end of the connecting portion 471 is connected to the vibration ring 45 (specifically, the second ring portion 45a of the vibration ring 45), and the other end of the connecting portion 471 is connected to the vibrator 472. The vibrator 472 can generate vibrations, and the vibrator 472 transmits the generated vibrations to the vibration ring 45 through the connecting portion 471. The specific structure of the vibrator 472 can refer to the prior art.

[0068] Please refer again Fig.12The vibration blanking unit also includes two sliding rings 49 arranged on the fourth mounting plate 44 relatively along the height direction, wherein an annular groove 442 is arranged on the fourth mounting plate 44, and the matching through hole 441 is opened on the inner bottom surface of the annular groove 442, and the annular groove 442 and the matching through hole 441 are coaxially arranged; the sliding ring 49 located below is coaxially arranged on the inner bottom surface of the annular groove 442 (that is, the upper surface of the matching through hole 441), and the vibration ring 45 is coaxially penetrated in the two sliding rings 49 along the height direction, and the sliding ring 49 is provided with a plurality of balls 491 along its circumference, and a second ring portion 45a is coaxially arranged on the outer periphery of the vibration ring 45; along the height direction, the second ring portion 45a is arranged between the two sliding rings 49, and the upper surface and the lower surface of the second ring portion 45a are in rolling contact with the balls 491 on the two sliding rings 49 respectively.

[0069] The outer diameter of the second ring portion 45a is smaller than the inner diameter of the annular groove 442. This design is to facilitate the vibration of the vibration ring 45 to vibrate within a certain range. The ball 491 on the sliding ring 49 can improve the flexibility of the vibration of the vibration ring 45, and can transmit the vibration of the vibrator 472 to the valve core to the maximum extent, so as to facilitate the smooth press-fitting of the valve core.

[0070] A working method of the valve core assembly tool in the embodiment of the present application is as follows:

[0071] 1. The telescopic end of the telescopic driving member 6 extends out until the telescopic end of the telescopic driving member 6 pushes open the pressure block 232 of a certain clamping mechanism 2, and the external manipulator takes away the oil circuit board 7 on the clamping mechanism 2, and then the manipulator installs a new oil circuit board 7 on the clamping mechanism 2. Specifically, the external manipulator (not shown) picks up the oil circuit board 7, and aligns the positioning hole 72 on the oil circuit board 7 with the positioning pin 222 on the vertical plate 21 and then inserts it, so that the oil circuit board 7 is positioned on the vertical plate 21, and then the telescopic end of the telescopic driving member 6 retracts. At this time, due to the elastic reset of the second elastic member 236, the pressure block 232 instantly presses the oil circuit board 7 on the clamping mechanism 2;

[0072] 2. The clamping mechanism 2 with the oil circuit board 7 installed follows the turntable 1 and rotates to between the pressing mechanism 3 and the blanking mechanism 4. At this time, the clamping mechanism 2 located between the pressing mechanism 3 and the blanking mechanism 4 is defined as the target clamping mechanism 2a;

[0073] 3. The third slide rail 42 drives the third mounting plate 43 and the vibration blanking unit to descend until the lower end of the guide cylinder 46 of the vibration blanking unit is at least partially inserted into the mounting hole 71 of the oil circuit board 7;

[0074] Fourth, the external manipulator picks up the valve core to be press-fitted and puts it into the guide cylinder 46. The first slide rail 32 drives the pressure head 37 to move horizontally until the pressure head 37 is located directly above the mounting hole 71. At the same time, the vibration generating module 47 starts to drive the vibration ring 45 to vibrate, and the vibration ring 45 drives the guide cylinder 46 to vibrate. The second slide rail 34 also drives the second mounting plate 35, the mounting seat 36 and the pressure head 37 to move downward together. The pressure head 37 gradually falls and contacts the valve core. The first elastic member 38 gives the valve core a downward elastic force through the pressure head 37. Under the action of the pressure head 37 and the shaking of the guide cylinder 46, the valve core gradually falls downward into the mounting hole 71.

[0075] 5. After the valve core is pressed into place, the valve core is blocked and cannot move downward any further, but the second slide rail 34 continues to drive the second mounting plate 35 and the displacement sensor 39 on the second mounting plate 35 to move downward, so the length of the pull rod 391 of the displacement sensor 39 is gradually compressed, and the displacement sensor 39 senses the signal amount and sends the signal amount to the external system, which controls the second slide rail 34 to stop moving downward and lifts the pressure head 37 upward through the external system;

[0076] 6. After the lifting is completed, the first slide rail 32 moves horizontally, driving the second mounting plate 35 and the pressure head 37 away from the target clamping mechanism 2a, and then the third slide rail 42 drives the vibration blanking unit to lift upward;

[0077] 7. The turntable 1 rotates to transfer the next clamping mechanism 2 equipped with the oil circuit board 7 between the blanking mechanism 4 and the pressing mechanism 3, and then repeat the above steps 3 to 6.

[0078] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the protection scope of the present application is not limited to this. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in this application, and these modifications or replacements should be included in the protection scope of this application.
