Description

Technical Field

[0001] This invention relates to the field of actuator technology, specifically to a dual-actuator integrated control mechanism and its operation method. Background Technology

[0002] Electrically controlled actuators use a drive motor to achieve reciprocating motion of the actuator through a transmission mechanism. Existing electrically controlled actuators typically use one motor to independently drive one actuator to achieve reciprocating motion. When multiple actuators need to perform independent reciprocating motion, multiple motors are required for control, which results in high costs and places significant demands on the overall workspace design.

[0003] Therefore, it is necessary to propose a dual-actuator integrated control mechanism and its operation method. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-actuator integrated control mechanism and operating method to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A dual-actuator integrated control mechanism includes a housing, a drive motor, a first lifting cam, and a second lifting cam. The first and second lifting cams are integrally formed with a load shaft. The output end of the drive motor drives the load shaft through a transmission structure. The first and second lifting cams are symmetrically structured and are respectively located on both sides of the load shaft, arranged one in front of the other. The housing is integrally formed with a first slide rail and a second slide rail. A first roller tappet is slidably installed in the first slide rail, and a second roller tappet is slidably installed in the second slide rail. The first roller tappet cooperates with the first lifting cam to drive sliding, and the second roller tappet cooperates with the second lifting cam to drive sliding.

[0007] According to the above technical solution, the first slide rail and the second slide rail are respectively integrally formed with locking blocks. The first roller tappet and the second roller tappet have the same structure, and their outer circumference is provided with circumferentially distributed tappet grooves. The tappet grooves cooperate with the locking blocks.

[0008] According to the above technical solution, a first slide rod is installed on the non-roller end of the first roller taper, and a second slide rod is installed on the non-roller end of the second roller taper. The first slide rod and the second slide rod have the same structure, and a circumferentially distributed slide rod groove is formed on their outer circumference. The slide rod groove and the locking block cooperate with each other to slide. The first slide rod is slidably installed in the first slide track, and the second slide rod is slidably installed in the second slide track. The mating end of the first slide rod is integrally formed with circumferentially distributed oblique pointed teeth, and the non-roller end of the first roller taper is integrally formed with circumferentially distributed wavy teeth. The wavy teeth and the oblique pointed teeth cooperate with each other, and the number of both is the same. The number of oblique pointed teeth is twice the number of slide rod grooves. The upper end face of the locking block is inclined.

[0009] According to the above technical solution, spring seats are fixedly installed in the middle of the first slide rod and the second slide rod respectively, and a spring is provided between the top plate of the outer shell and the spring seat. The two springs are respectively fitted onto the first slide rod and the second slide rod.

[0010] According to the above technical solution, the clockwise end of the first lifting cam is integrally formed with a first stop protrusion, and the counterclockwise end of the second lifting cam is integrally formed with a second stop protrusion.

[0011] According to the above technical solution, the first roller tap and the first slide rod have the same diameter. Both the first slide rod and the first roller tap are provided with hollow holes. The bottom end of the first slide rod is fitted with a positioning pin, and the positioning pin cooperates with the hollow hole of the first roller tap.

[0012] According to the above technical solution, the transmission structure between the drive motor and the load shaft is a worm gear meshing structure.

[0013] An operating method for a dual-actuator integrated control mechanism includes the following steps:

[0014] When the steps and devices are in the initial state, the first operation command is input, causing the drive motor to rotate in the forward direction, which in turn drives the first lifting cam and the second lifting cam to rotate clockwise. The first lifting cam enters its lifting part, and the second lifting cam enters its base circle part.

[0015] Step 1: The first lifting cam lifts the first roller tappet, thereby lifting the first slide bar.

[0016] Step 1: After the slide groove of the first slide rod disengages from the locking block, the first slide rod rotates along its own axis in the first step by the compression force of the spring and the misalignment and meshing of the helical pointed teeth and wave teeth, thus realizing the first misalignment between the slide groove and the locking block.

[0017] Step 1: Drive motor rotates in the opposite direction to achieve counterclockwise rotation of turbine and first lifting cam. First roller tappet falls back to initial state. First slide bar falls back under the action of spring. Through the misaligned engagement of locking block and helical teeth, first slide bar rotates along its own axis in the second step, so that the first slide bar is locked in position by locking block.

[0018] Step 1: When the first slide bar needs to be reset, the drive motor rotates forward again, driving the first lifting cam to rotate clockwise, causing the first roller push rod to lift and slide until the first slide bar is lifted again.

[0019] Step 1: After the first slide bar is lifted away from the locking block by the locking block for the second time, under the pressure of the spring and the misalignment of the inclined sharp teeth and the wave teeth, the first slide bar rotates along its own axis for the third time, realizing the second misalignment between the slide bar groove and the locking block.

[0020] Step 1: The drive motor rotates in the opposite direction again. The first roller tappet and the first slide bar fall back under the action of the spring. The first slide bar rotates along its own axis in the fourth step through the misalignment of its helical teeth and the locking block, so that the slide bar groove and the locking block are aligned and then return to the initial state. During the above operation, the second lifting cam enters its base circle part, and the second roller tappet and the second slide bar remain stationary.

[0021] In the initial state, the drive motor performs the operations from step to step, but its working drive sequence is reverse drive → forward drive → reverse drive → forward drive. The second lifting cam enters its lifting part to realize the operation of ejecting, locking and resetting the second slide rod. During this operation, the first lifting cam enters its base circle part, and the first roller tappet and the first slide rod remain stationary.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0023] By driving the motor to rotate in the forward and reverse directions, the turbine drives the first lifting cam and the second lifting cam to rotate as required. Under the action of the first lifting cam and the second lifting cam, the first roller tappet and the second lifting tappet push out the first slide rod and the second slide rod. Based on the combination of locking block, wave tooth and helical tooth, a rotation locking structure is formed, thereby realizing the position locking and unlocking control of the first slide rod and the second slide rod.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] Please see Figure 1-11 This invention provides a technical solution: a dual-actuator integrated control mechanism, including a housing 1, a drive motor 2, a first lifting cam 5, and a second lifting cam 6. The first lifting cam 5 and the second lifting cam 6 are integrally formed with a load shaft. The output end of the drive motor 2 drives the load shaft through a transmission structure. The first lifting cam 5 and the second lifting cam 6 are symmetrical structures, respectively located on both sides of the load shaft, and arranged one in front of the other. The housing 1 is integrally formed with a first slide rail 11 and a second slide rail 12. A first roller tap 7 is slidably installed in the first slide rail 11, and a second roller tap 9 is slidably installed in the second slide rail 12. The first roller tap 7 cooperates with the first lifting cam 5 to drive sliding, and the second roller tap 9 cooperates with the second lifting cam 6 to drive sliding.

[0046] The drive motor 2 drives the load shaft, which in turn drives the first lifting cam 5 and the second lifting cam 6 to turn. The first lifting cam 5 drives the first roller tappet 7 to turn clockwise, and the second lifting cam 6 drives the second roller tappet 9 to turn counterclockwise. This results in different control results when the drive motor 2 turns in different directions. The first slide rail 11 limits the first roller tappet 7 axially, and the second slide rail 12 limits the second roller tappet 8 axially.

[0047] Specifically, the first slide rail 11 and the second slide rail 12 are each integrally formed with a locking block 18. The first roller tap 7 and the second roller tap 9 have the same structure, and their outer periphery is provided with a circumferentially distributed tap groove 13. The tap groove 13 cooperates with the locking block 18.

[0048] The circumferential rotation of the first roller tap 7 and the second roller tap 8 is limited by the cooperation between the tap spool groove 13 and the locking block 18.

[0049] Specifically, the non-roller end of the first roller pusher 7 is fitted with a first slide bar 8, and the non-roller end of the second roller pusher 9 is fitted with a second slide bar 10. The first slide bar 8 and the second slide bar 10 have the same structure, and their outer circumference is provided with circumferentially distributed slide bar grooves 14. The slide bar grooves 14 cooperate with the locking block 18 to slide. The first slide bar 8 is slidably installed in the first slide rail 11, and the second slide bar 10 is slidably installed in the second slide rail 12. The mating end of the first slide bar 8 is integrally formed with circumferentially distributed oblique pointed teeth 17, and the non-roller end of the first roller pusher 7 is integrally formed with circumferentially distributed wavy teeth 16. The wavy teeth 16 and the oblique pointed teeth 17 cooperate with each other, and the number of both is the same. The number of oblique pointed teeth 17 is twice the number of slide bar grooves 14. The upper end surface of the locking block 18 is inclined.

[0050] The sliding groove 14 is set and effectively cooperates with the locking block 18 to realize the sliding and position locking of the first sliding rod 8 and the second sliding rod 10 in the first slide rail 11 and the second slide rail 12. The cooperation of the helical pointed teeth 17 and the wave teeth 16 makes the first sliding rod 8 and the first roller tap 7 have a relative rotation tendency, and the second sliding rod 10 and the second roller tap 9 have a relative rotation tendency. By the ratio of the number of helical pointed teeth 17 to the number of grooves, the odd number of teeth will be limited, and the even number of teeth will be released from the limit.

[0051] Specifically, spring seats are fixedly installed in the middle of the first slide rod 8 and the second slide rod 10 respectively, and a spring 15 is provided between the top plate of the outer shell 1 and the spring seat. The two springs 15 are respectively fitted onto the first slide rod 8 and the second slide rod 10.

[0052] The spring seat provides mechanical conditions for the installation and operation of the spring 15. Based on the misaligned meshing of the helical pointed teeth 17 and the wave teeth 16, when the first slide rod 8 is released from the restraint of the locking block 18, the spring 15 provides power for the first slide rod 8 and the second slide rod 10 to rotate along their own axis, and at the same time provides power for the first slide rod 8 and the second slide rod 10 to fall back.

[0053] Specifically, the first lifting cam 5 has a first stop protrusion integrally formed at its clockwise end, and the second lifting cam 6 has a second stop protrusion integrally formed at its counterclockwise end.

[0054] Over-rotation is prevented by using the first and second stop protrusions.

[0055] Specifically, the first roller tap 7 and the first slide rod 8 have the same diameter. Both the first slide rod 8 and the first roller tap 7 have hollow holes. The bottom end of the first slide rod 8 is fitted with a positioning pin, which cooperates with the hollow hole of the first roller tap 7.

[0056] By setting the diameter, the movement of the entire device can be made more stable and smooth. At the same time, the positioning pin and hollow hole ensure effective combination and improve stability when relative rotation occurs.

[0057] Specifically, the transmission structure between the drive motor 2 and the load shaft is a meshing structure of a turbine 4 and a worm gear 3.

[0058] A known stable transmission method is provided.

[0059] An operating method for a dual-actuator integrated control mechanism includes the following steps:

[0060] Step 1: The device is in its initial state, such as... Figure 6 Inputting the first operation command causes the drive motor 2 to rotate in the forward direction, which in turn drives the first lifting cam 5 and the second lifting cam 6 to rotate clockwise. The first lifting cam 5 enters its lifting part, and the second lifting cam 6 enters its base circle part.

[0061] Step 2: The first lifting cam 5 lifts the first roller tappet 7, thereby lifting the first slide bar 8. At this time, under the restraint of the locking block 18, the wavy teeth 16 and the helical pointed teeth 17 of the first roller tappet 7 and the first slide bar 8 are in a misaligned meshing state. The second lifting cam keeps the second roller tappet 9 stationary, and the first slide bar 8 remains stationary. Figure 7 ;

[0062] Step 3: After the slide groove 14 of the first slide rod 8 disengages from the locking block 18, as follows... Figure 8a Through the compressive force of spring 15 and the misaligned meshing of the helical teeth 17 and the wave teeth 16, such as Figure 8b This causes the first slide bar 8 to rotate along its own axis in the first step, realizing the first misalignment between the slide bar groove 14 and the locking block 18, as shown below. Figure 8c ;

[0063] Step 4: The drive motor 2 rotates in the opposite direction, causing the turbine 4 and the first lifting cam 5 to rotate counterclockwise, and the first roller tappet 7 returns to its initial state. Figure 9a The first sliding rod 8 falls back under the action of the spring 15, and through the misaligned engagement of the locking block 18 and the helical pointed tooth 7, as... Figure 8cThis causes the first slide bar 8 to rotate along its own axis in the second step, thereby locking the first slide bar 8 in position with the locking block 18. Figure 9b ;

[0064] Step 5: When the first slide bar 8 needs to be reset, the drive motor 2 rotates forward again, driving the first lifting cam 5 to rotate clockwise, causing the first roller push rod to lift and slide until the first slide bar 8 is lifted again. Figure 10a ;

[0065] Step 6: After the first sliding rod 8 is lifted a second time away from the locking restraint of the locking block 18, under the pressure of the spring 15 and the misaligned meshing of the helical pointed teeth 17 and the wave teeth 16, as... Figure 10b This causes the first sliding rod 8 to rotate a third time along its own axis, achieving a second misalignment between the sliding rod groove 14 and the locking block 18, as shown below. Figure 10c ;

[0066] Step 7: The drive motor 2 rotates in the opposite direction again. The first roller tappet 7 and the first slide bar 8 fall back under the action of the spring 15. The first slide bar 8 engages with the locking block 18 through the misalignment of its helical teeth 7. Figure 10c This causes the first slide bar 18 to rotate in the fourth step along its own axis, thereby aligning the slide bar groove 14 with the locking block 18. Figure 10d Then it returns to the initial state, such as Figure 6 During the above operation, the second lifting cam 6 enters its base circle portion, while the second roller tappet 9 and the second slide bar 10 remain stationary.

[0067] Step 8: In the initial state, the drive motor 2 performs the operations of steps 1 to 7, but its working drive sequence is reverse drive → forward drive → reverse drive → forward drive. The second lifting cam 6 enters its lifting part to realize the operation of ejecting, locking and resetting the second slide rod 10. During this operation, the first lifting cam 5 enters its base circle part, and the first roller tap 7 and the first slide rod 8 remain stationary.
