Description

Technical Field

[0001] This invention relates to the field of transmission hydraulic module manufacturing technology, specifically to a solenoid valve press-fitting device for transmission hydraulic modules. Background Technology

[0002] The hydraulic module of the transmission is a crucial component for enabling automatic gear shifting. When assembling the solenoid valves on the transmission hydraulic module, it is usually done manually with the help of tooling to press the solenoid valves into the hydraulic module. However, although this assembly method is simple and low-cost, manual operation cannot precisely control the pressing force, which can easily damage the solenoid valves and lead to substandard quality of the solenoid valves or hydraulic modules. At the same time, this pressing method is too inefficient and labor-intensive for operators, making it unsuitable for mass production. Summary of the Invention

[0003] To address the above problems, this invention provides a solenoid valve press-fitting device for a transmission hydraulic module that offers high assembly efficiency and good press-fitting quality.

[0004] The technical solutions to the above technical problems are as follows:

[0005] A solenoid valve press-fitting device for a transmission hydraulic module includes a frame assembly and an electrical cabinet. The frame assembly includes a lower frame and an upper frame, with a first station and a second station located within the upper frame. The device also includes:

[0006] A first positioning and clamping mechanism for clamping and positioning the hydraulic module at the first station;

[0007] A second positioning and clamping mechanism for clamping and positioning the hydraulic module at the second work station;

[0008] A clamping mechanism used to press the solenoid valve into the hydraulic module;

[0009] The clamping mechanism includes a support plate, a first servo electric cylinder, a second servo electric cylinder, a first slider, and a first pressure head mechanism;

[0010] The support plate is fixed on the upper frame. The support plate is provided with a waist-shaped through hole and a first slide rail and a second slide rail. The first slide rail is located on one side of the waist-shaped through hole, and the second slide rail is located on the other side of the waist-shaped through hole.

[0011] The first slider is connected to the output end of the first servo cylinder. The first slider slides in cooperation with the first slide rail and the second slide rail. The second servo cylinder is mounted on the first slider. The first pressure head mechanism is connected to the output end of the second servo cylinder. The first servo cylinder drives the first slider to slide along the first slide rail and the second slide rail, so that the second servo cylinder moves above the first pressure head mechanism. After the output end of the second servo cylinder passes through the waist-shaped through hole, it pushes the first pressure head mechanism to press the solenoid valve of the hydraulic module, which is positioned and clamped in the first station, into the hydraulic module.

[0012] The beneficial effects of this invention are as follows: This invention utilizes a first servo electric cylinder, a second servo electric cylinder, a first slider, and a first pressing head mechanism. The first servo electric cylinder pushes the first slider along the first and second slide rails, causing the second servo electric cylinder to move above the first pressing head mechanism. The second servo electric cylinder then pushes the first pressing head mechanism, causing it to press the solenoid valve of the hydraulic module into the hydraulic module. This invention solves the problem of the great difficulty in assembling solenoid valves in hydraulic modules in the prior art, reduces the probability of damaging the solenoid valve, reduces manual labor intensity, and improves production efficiency.

The first grating 64, the second grating 65, the third grating 66, and the fourth grating 67 are respectively fixed on the upper shelf 2.

[0039] In this implementation scheme, before press-fitting, the worker first pre-installs the first solenoid valve A1, the second solenoid valve A2, the third solenoid valve A3, the fourth solenoid valve A4, the fifth solenoid valve A5, the sixth solenoid valve A6, the seventh solenoid valve A7, and the eighth solenoid valve A8 on the hydraulic module A. Then, a pressure sleeve G1 is fitted onto each solenoid valve. Specifically, the first solenoid valve A1, the second solenoid valve A2, the third solenoid valve A3, the fourth solenoid valve A4, and the fifth solenoid valve A5 are pre-installed on one side of the hydraulic module A, while the sixth solenoid valve A6, the seventh solenoid valve A7, and the eighth solenoid valve A8 are pre-installed on the other side of the hydraulic module A. The pressure sleeve G1 is fitted to protect the solenoid valves, thereby preventing damage to the solenoid valves during the press-fitting process.

[0040] The first positioning and clamping mechanism includes a first positioning block 70, a fourth positioning block 70a, a first clamping cylinder 71, a second clamping cylinder 72, a third clamping cylinder 73, a first clamping block 74, a second clamping block 75, and a third clamping block 76. The first positioning block 70, the fourth positioning block 70a, the first clamping cylinder 71, the second clamping cylinder 72, and the third clamping cylinder 73 are mounted on the first pressure head mounting base 30. The first clamping cylinder 71, the second clamping cylinder 72, and the third clamping cylinder 73 are located on one side of the first pressure head mounting base 30, and the first clamping block 74, the second clamping block 75, and the third clamping block 76 are located on the other side of the first pressure head mounting base 30. The first clamping block 74, the second clamping block 75, and the third clamping block 76 are respectively connected to the pistons of the first clamping cylinder 71, the second clamping cylinder 72, and the third clamping cylinder 73.

[0041] The second positioning and clamping mechanism includes a second positioning block 80, a third positioning block 81, a fourth clamping cylinder 82, a fifth clamping cylinder 83, a sixth clamping cylinder 84, a fourth clamping block 85, a fifth clamping block 86, and a sixth clamping block 87. The second positioning block 80, the third positioning block 81, the fourth clamping cylinder 82, the fifth clamping cylinder 83, and the sixth clamping cylinder 84 are mounted on the second pressure head mounting base 31. The fourth clamping cylinder 82, the fifth clamping cylinder 83, and the sixth clamping cylinder 84 are located on one side of the second pressure head mounting base 31, and the fourth clamping block 85, the fifth clamping block 86, and the sixth clamping block 87 are located on the other side of the second pressure head mounting base 31. The fourth clamping block 85, the fifth clamping block 86, and the sixth clamping block 87 are respectively connected to the pistons of the fourth clamping cylinder 82, the fifth clamping cylinder 83, and the sixth clamping cylinder 84.

[0042] In this embodiment, the equipment is equipped with a first station and a second station. To improve pressing efficiency, at least two workers are required to load the hydraulic module A. When positioning and clamping the hydraulic module A within the first press head mounting seat 30, the bottom of the hydraulic module A is first placed on the first positioning block 70 and the fourth positioning block 70a for positioning. Then, the first clamping cylinder 71, the second clamping cylinder 72, and the third clamping cylinder 73 are activated. Simultaneously, the pistons of the first clamping cylinder 71, the second clamping cylinder 72, and the third clamping cylinder 73 extend, driving the first clamping block 74, the second clamping block 75, and the third clamping block 76 to rotate clockwise or counterclockwise by 90 degrees. Then, the first clamping cylinder 71, the second clamping cylinder 72, and the third clamping cylinder 73 are activated. The piston of the first clamping cylinder 71 retracts, thereby clamping the hydraulic module A by the first clamping block 74, the second clamping block 75, and the third clamping block 76. During the positioning and clamping of the hydraulic module A, the worker holds the hydraulic module A and sends it into the first work station. After the hydraulic module A is positioned and clamped, there are a first notch Q1 and a second notch Q2 between the hydraulic module A and the first pressure head mounting seat 30. The first notch Q1 and the second notch Q2 provide sufficient space for the worker to put the hydraulic module A into the first pressure head mounting seat 30 for easy loading, and also prevent fingers from being pinched.

[0043] After one worker positions and clamps the hydraulic module A in the first workstation using the aforementioned method, the worker simultaneously presses the first button 60 and the second button 61. If there are no obstructions between the first grating 64 and the second grating 65, the electrical cabinet 3 will supply power to the first servo cylinder 5, causing it to start working. The first servo cylinder 5 pushes the first slider 9 and the second servo cylinder 6 to the left on the first slide rail 11 and the second slide rail 12. When the output end of the second servo cylinder 6 aligns with the first first pressure head assembly below, the first servo cylinder 5 stops working, and the second servo cylinder 6 starts working. At this time, the second servo cylinder 6 will push the first first pressure head assembly (the rightmost first pressure head assembly) downwards, causing the rightmost first pressure head assembly to contact the pressure sleeve G1 on the fifth solenoid valve A5. The second servo cylinder 6 continues to provide downward pressure, thereby pressing the fifth solenoid valve A5 into the hydraulic module A. After pressing the fifth solenoid valve A5, the second servo cylinder 6 rises back to its initial position. The first servo cylinder 5 pushes the first slider 9 and the second servo cylinder 6 to the left on the first slide rail 11 and the second slide rail 12, so that the output end of the second servo cylinder 6 is aligned with the second first pressure head assembly below, thereby pressing the fourth solenoid valve A4 into the hydraulic module A. Following the above steps, the second servo cylinder 6 presses the first solenoid valve A1, the second solenoid valve A2, and the third solenoid valve A3 into the hydraulic module A. After the first solenoid valve A1, the second solenoid valve A2, the third solenoid valve A3, the fourth solenoid valve A4, and the fifth solenoid valve A5 are all pressed into the hydraulic solenoid valve A, the first servo cylinder 5 drives the first slider 9 and the second servo cylinder 6 to move to the right on the first slide rail 11 and the second slide rail 12 and return to the initial position. At this time, it is indicated that the first solenoid valve A1, the second solenoid valve A2, the third solenoid valve A3, the fourth solenoid valve A4, and the fifth solenoid valve A5 have all been pressed into place. Then, the worker at the first station takes out the hydraulic module A and manually hands it to the worker at the second station.

[0044] After the hydraulic module A, with the first solenoid valve A1, second solenoid valve A2, third solenoid valve A3, fourth solenoid valve A4, and fifth solenoid valve A5 pre-installed, is handed to the worker at the second station, the worker at the second station rotates the hydraulic module A 180 degrees clockwise and positions it on the second pressure head mounting seat 31 via the second positioning block 80 and the third positioning block 81. Then, the worker activates the fourth clamping cylinder 82, the fifth clamping cylinder 83, and the sixth clamping cylinder 84. As the pistons of the fourth clamping cylinder 82, the fifth clamping cylinder 83, and the sixth clamping cylinder 84 extend, they simultaneously drive the fourth clamping block 85, the fifth clamping block 86, and the sixth clamping block 87 to rotate 90 degrees clockwise or counterclockwise, respectively. Then, the pistons of the fourth clamping cylinder 82, the fifth clamping cylinder 83, and the sixth clamping cylinder 84 retract, thereby clamping the hydraulic module A with the fourth clamping block 85, the fifth clamping block 86, and the sixth clamping block 87.

[0045] After the worker at the second station positions and clamps the hydraulic module A onto the second pressure head mounting base 31 as described above, the worker simultaneously presses the third button 62 and the fourth button 63. If no foreign object is detected between the third grating 66 and the fourth grating 67, the electrical cabinet 3 provides power to the third servo cylinder 20, causing it to start working. The third servo cylinder 20 pushes the second slider 22 and the fourth servo cylinder 21 to the left on the first slide rail 11 and the second slide rail 12. When the fourth servo cylinder 21 aligns with the lower rightmost second pressure head assembly, the third servo cylinder 20 stops working, and the fourth servo cylinder 21 starts. At this time, the output end of the fourth servo cylinder 21 pushes the second pressure head assembly downward, causing the rightmost second pressure head assembly to contact the pressure sleeve G1 on the eighth solenoid valve A8. The fourth servo cylinder 21 continues to apply downward pressure, thereby causing the second pressure head assembly to press the eighth solenoid valve A8 into the hydraulic module A. After the eighth solenoid valve A8 is pressed in, the fourth... Servo cylinder 21 rises back to its initial position, while the rightmost second pressure head assembly returns to its initial external position. The third servo cylinder 20 pushes the second slider 22 and the fourth servo cylinder 21 to the left on the first slide rail 11 and the second slide rail 12, so that the output end of the fourth servo cylinder 21 is aligned with another second pressure head assembly, and the second pressure head assembly is pressed down, so that the second pressure head assembly presses the seventh solenoid valve A7 into the hydraulic module A. Following the above steps, the sixth solenoid valve A6 is also pressed into the hydraulic module A. After the fourth servo cylinder 21 has pressed the sixth solenoid valve A6, the seventh solenoid valve A7, and the eighth solenoid valve A8 into the hydraulic module A, the third servo cylinder 20 drives the second slider 22 and the fourth servo cylinder 21 to move to the right on the first slide rail 11 and the second slide rail 12 and return to their initial positions. At this time, it is indicated that the sixth solenoid valve A6, the seventh solenoid valve A7, and the eighth solenoid valve A8 have all been pressed into place, and the worker at the second station can operate the equipment to remove the hydraulic solenoid valve A.

[0046] In this embodiment, the maximum stroke of the first servo electric cylinder 5 is 250mm, and the maximum stroke of the third servo electric cylinder 20 is 150mm.

[0047] In this embodiment, when the second servo cylinder 6 pushes the first pressure head assembly downwards, the output end of the second servo cylinder 6 first contacts the first upper pressure head 40 and pushes the first pressure rod 42 downwards. At this time, the first upper rectangular spring 41 is gradually compressed. Before this, the first lower pressure head 48 will first contact the pressure sleeve G1 on the first solenoid valve A1 / second solenoid valve A2 / third solenoid valve A3 / fourth solenoid valve A4 / fifth solenoid valve A5. At the same time, the first lower rectangular spring 47 will be subjected to the upward pushing force of the pressure sleeve G1. The first lower pressure head 48 contacts the upper surface of the pressure sleeve G1, mainly to straighten the solenoid valve. When the second servo cylinder 6 pushes the first pressure head assembly downwards, the output end of the second servo cylinder 6 first contacts the first upper pressure head 40 and pushes the first pressure rod 42 downwards. When the servo cylinder 6 continuously pushes the first pressure rod 42 up and down, the first pressure rod 42 will pass through the first lower clamping head 48, and then the first pressure rod 42 will press down on the pressure sleeve G1. The pressure sleeve G1 presses against the first solenoid valve A1 / second solenoid valve A2 / third solenoid valve A3 / fourth solenoid valve A4 / fifth solenoid valve A5, thereby pressing the first solenoid valve A1 / second solenoid valve A2 / third solenoid valve A3 / fourth solenoid valve A4 / fifth solenoid valve A5 into the hydraulic module A. When the second servo cylinder 6 rises back to the initial position, the first upper rectangular spring 41 releases its own spring force, so that the first pressure rod 42 and the first upper clamping head 40 return to their initial external position.

[0048] In this embodiment, when the fourth servo cylinder 21 pushes the second pressure head assembly downwards, the output end of the fourth servo cylinder 21 first contacts the second upper pressure head 50 and pushes the second pressure rod 52 downwards. At this time, the second upper rectangular spring 51 is gradually compressed. Before this, the second lower pressure head 58 will first contact the pressure sleeve G1 on the eighth solenoid valve A8 / seventh solenoid valve A7 / sixth solenoid valve A6. At the same time, the second lower rectangular spring 57 will be subjected to the upward pushing force of the pressure sleeve G1. The upper surface of the pressure sleeve G1 where the second lower pressure head 58 contacts the second lower pressure head 58 mainly serves to straighten the electromagnetic valve. The function of the valve is as follows: when the fourth servo cylinder 21 pushes the second rod 52 downward, the second pressure rod 52 will pass through the second lower clamping head 58, and then the second pressure rod 52 will press down on the pressure sleeve G1. The pressure sleeve G1 will press against the eighth solenoid valve A8 / seventh solenoid valve A7 / sixth solenoid valve A6, thereby pressing the eighth solenoid valve A8 / seventh solenoid valve A7 / sixth solenoid valve A6 into the hydraulic module A. When the fourth servo cylinder 21 rises back to the initial position, the second upper rectangular spring 51 releases its own spring force, so that the second pressure rod 52 and the second upper clamping head 50 return to their initial external position.

[0049] In this implementation scheme, when an emergency occurs or the hydraulic module A is not properly positioned and clamped, the alarm light D will emit an alarm light to remind the worker. Furthermore, the worker can operate the touch screen C to set the relevant programs of the entire equipment (e.g., the pressure of pressing by all servo electric cylinders) and the pressing process parameters.

[0050] Finally, it should be noted that the above-described embodiments are merely preferred embodiments of the present invention used to illustrate the technical solutions of the present invention, and are not intended to limit them, much less limit the scope of protection of the present invention; although the invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to depart from the scope of protection of the claims.
