Description

Technical Field

[0001] The present invention relates to a device for opening shaft holes in an actuator housing and a method for using the same. Background Art

[0002] A pneumatic actuator is an automated device powered by compressed air and is widely used in the industrial control field to drive the movement of devices such as valves and robotic arms. The pneumatic actuator utilizes the pressure energy of compressed air to drive mechanical components to move. Its working principle can be summarized as follows: by controlling the on / off and direction of the air flow, linear or rotational motion is generated in actuators such as cylinders or pneumatic motors, thereby achieving the operation of the controlled object.

[0003] During the production process of a pneumatic actuator, shaft holes for inserting inclined fork are required to be opened on the surface of the housing. However, during the existing process of opening the shaft holes, workers need to continuously move the position of the housing so that the position to be drilled is adapted to the drill bit, which consumes more working time and cost and reduces the overall working efficiency. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a device for opening shaft holes in an actuator housing and a method for using the same. After placing the actuator housing in the limiting area, as the elastic member rebounds, the elastic force acts on the baffle in the opposite direction, causing the two limiting plates to approach each other, reducing the limiting area, thereby clamping and fixing the actuator housing, improving the stability of the actuator housing during drilling. And when the actuator housing is fixed, by rotating the third screw, with the cooperation of the third sliding sleeve, rotational limitation is applied to the third threaded sleeve, allowing the third threaded sleeve to move on the third screw, and then driving the movement of the moving plate to adjust the lateral distance of the actuator housing. Start the second motor, rotate the second screw, and as the second sliding sleeve slides along the length direction of the second sliding rod, rotational limitation is applied to the second sliding sleeve, allowing the second threaded sleeve to move on the second screw. Under the connection of the first connecting pin, the bearing plate follows the movement to adjust the longitudinal distance of the actuator housing. The fully mechanized movement makes the actuator housing move directly below the drilling bit more precisely, improving the accuracy and efficiency of shaft hole opening.

The limiting component is arranged on the surface of the bearing plate, and the actuator housing to be drilled is fixed on the bearing plate through the limiting component. The bearing plate changes the position of the actuator housing through the lateral adjustment component and the longitudinal adjustment component respectively, so that the drilling position of the actuator housing is directly below the drilling bit. Among them, as the height adjustment component changes the distance between the hole-opening drill bit and the actuator housing, hole opening is achieved.

A first motor is arranged on the upper surface of the fixed frame. A first screw rod is arranged inside the fixed frame. On both sides of the first screw rod, there are two first sliding rods parallel to the first screw rod respectively. The power output end of the first motor is connected to the first screw rod.

[0007] As a preferred technical solution of the present invention, a first threaded sleeve is sleeved on the first screw rod.

First connecting pins are arranged on the upper surfaces of the second threaded sleeve and the second sliding sleeve. The first connecting pins are connected to the bearing plate.

[0010] As a preferred technical solution of the present invention, the transverse adjustment component includes a base arranged on the upper surface of the frame. A second bearing seat is centrally arranged on the upper surface of the base. On both sides of each second bearing seat, two second fixing seats are symmetrically arranged. A third screw rod is inserted into the second bearing seats. A third sliding rod is inserted into two non-adjacent second fixing seats. The third sliding rod and the third screw rod are parallel to each other.

A second connecting plate is arranged between the third threaded sleeve and the third sliding sleeve. Second connecting pins are arranged on the upper surfaces of the third threaded sleeve and the third sliding sleeve. The second connecting pins are connected to the moving plate.

[0012] As a preferred technical solution of the present invention, the limiting component includes a support block disposed on the upper surface of the bearing plate. A pull rod is inserted into the support block. One end of the pull rod is provided with a handle, and the other end of the pull rod is provided with a baffle. An elastic member is sleeved on the outer side of a section of the pull rod located between the baffle and the support block.

[0013] As a preferred technical solution of the present invention, a limiting plate is provided on the side of the baffle away from the pull rod. On the support block and vertically below the pull rod, a strip plate is further provided. The two sides of the strip plate are respectively connected to the baffle and the pull rod through support plates.

[0014] The present invention also provides a technical solution, a method for using a device for opening a shaft hole of an actuator housing, and the specific steps are as follows: S1. First, pull the two handles to move the pull rod in the direction of the handle, drive the limiting plate to move in the direction of the support block, and let the baffle squeeze the elastic member, thereby expanding the limiting area formed between the two limiting plates, and place the actuator housing to be drilled in the established area; S2.

After moving the actuator housing to the vertical lower side of the drilling bit, start the first motor. The power output end of the first motor drives the first screw rod to rotate. Due to the internal thread of the first thread sleeve being adapted to the outer thread of the first screw rod, as the first sliding sleeve slides along the length direction of the first sliding rod to limit the rotation of the first sliding sleeve, the first thread sleeve moves on the first screw rod, drives the lifting plate to descend, and makes the drilling bit move to the position where the shaft hole of the actuator is opened to complete the drilling.

[0015] Compared with the prior art, the beneficial effects that the present invention can achieve are as follows: After placing the actuator housing in the limiting area, as the elastic member rebounds, the elastic force acts on the baffle in the reverse direction, causing the two limiting plates to approach each other, reducing the limiting area, thereby clamping and fixing the actuator housing, improving the stability of the actuator housing during hole opening. And when the actuator housing is fixed, by rotating the third screw, with the cooperation of the third sliding sleeve, the rotation of the third threaded sleeve is limited, enabling the third threaded sleeve to move on the third screw, and then driving the movement of the moving plate to adjust the lateral distance of the actuator housing. Start the second motor, rotate the second screw, and as the second sliding sleeve slides along the length direction of the second sliding rod, the rotation of the second sliding sleeve is limited, enabling the second threaded sleeve to move on the second screw. Under the connection of the first connecting pin, the bearing plate follows the movement to adjust the longitudinal distance of the actuator housing. The fully mechanized movement makes the actuator housing move to directly below the vertical of the hole-opening drill bit, more precisely, improving the precision and efficiency of shaft hole opening.

DETAILED DESCRIPTION OF THE INVENTION

[0018] In order to make the technical means, creative features, achieved objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments can all be obtained from commercial channels unless otherwise specified.

[0019] Embodiment: As Figure 1 - Figure 6 As shown, this embodiment proposes a device for opening shaft holes in the housing of an actuator, including a frame 1, a height adjustment component, a lateral adjustment component, a longitudinal adjustment component and a limit component. The limit component is arranged on the surface of the carrier plate 2, and the actuator housing to be drilled is fixed on the carrier plate 2 through the limit component. The carrier plate 2 changes the position of the actuator housing through the lateral adjustment component and the longitudinal adjustment component respectively, so that the drilling position of the actuator housing is directly below the vertical position of the drilling bit 3. Among them, as the height adjustment component changes the distance between the drilling bit 3 and the actuator housing, drilling is achieved. After the actuator housing is placed in the limit area, with the rebound of the elastic member 37, the elastic force acts on the baffle 36 in the opposite direction, causing the two limit plates 38 to approach each other, reducing the limit area, thereby clamping and fixing the actuator housing, improving the stability of the actuator housing during drilling. And when the actuator housing is fixed, by rotating the third screw 26, with the cooperation of the third sliding sleeve 30, the rotation of the third threaded sleeve 29 is limited, so that the third threaded sleeve 29 moves on the third screw 26, and then drives the movement of the moving plate 12 to adjust the lateral distance of the actuator housing. Start the second motor 18, rotate the second screw 15, and as the second sliding sleeve 20 slides along the length direction of the second sliding rod 16, the rotation of the second sliding sleeve 20 is limited, so that the second threaded sleeve 19 moves on the second screw 15. Under the connection of the first connecting pin 22, the carrier plate 2 follows the movement to adjust the longitudinal distance of the actuator housing. The fully mechanized movement makes the actuator housing move to the vertical position below the drilling bit 3 more precisely.

[0020] The height adjustment assembly includes a fixed frame 4 disposed on the upper surface of the frame 1. A first motor 5 is provided on the upper surface of the fixed frame 4. A first screw rod 6 is disposed inside the fixed frame 4. On both sides of the first screw rod 6, two first slide rods 7 parallel to the first screw rod 6 are respectively provided. The power output end of the first motor 5 is connected to the first screw rod 6. A first threaded sleeve 8 is sleeved on the first screw rod 6. A first sliding sleeve 9 connected to the first threaded sleeve 8 is provided on the first slide rod 7. A lifting plate 10 is provided on the outer side of the first threaded sleeve 8. A fixing plate 11 is provided on the side of the lifting plate 10 away from the first threaded sleeve 8. The hole-opening drill 3 is inserted into the fixing plate 11. When the first motor 5 is started, the power output end of the first motor 5 drives the first screw rod 6 to rotate. Due to the adaptation of the internal thread of the first threaded sleeve 8 to the outer thread of the first screw rod 6, as the first sliding sleeve 9 slides along the length direction of the first slide rod 7, rotational limitation of the first sliding sleeve 9 is performed, enabling the first threaded sleeve 8 to move on the first screw rod 6, driving the lifting plate 10 to descend, and causing the hole-opening drill 3 to move to the position where the shaft hole of the actuator is to be opened, thereby realizing the adjustment of the height of the hole-opening drill 3. Moreover, a fourth motor for driving the hole-opening drill 3 is provided on the fixing plate 11. Since the driving method of the hole-opening drill 3 is prior art, it will not be elaborated here.

[0021] Further, the longitudinal adjustment assembly includes a moving plate 12. Two first bearing seats 13 are centrally arranged on the upper surface of the moving plate 12. Two first fixing seats 14 are symmetrically arranged on both sides of each first bearing seat 13. A second screw rod 15 is inserted into the first bearing seat 13. A second sliding rod 16 is inserted into two non-adjacent first fixing seats 14. The second sliding rod 16 is parallel to the second screw rod 15. An installation frame 17 is arranged on the upper surface of the frame 1. A second motor 18 is arranged on the installation frame 17. The installation frame 17 supports the second motor 18, so that the second motor 18 and the second screw rod 15 are at the same horizontal height. The power output end of the second motor 18 is connected to the second screw rod 15. A second thread sleeve 19 is sleeved on the second screw rod 15. A second sliding sleeve 20 is sleeved on the second sliding rod 16. A first connection plate 21 is arranged between the second thread sleeve 19 and the second sliding sleeve 20. First connection pins 22 are arranged on the upper surfaces of the second thread sleeve 19 and the second sliding sleeve 20. The first connection pins 22 are connected to the bearing plate 2. When the second screw rod 15 drives the second thread sleeve 19 to rotate, the rotation of the second thread sleeve 19 is limited through the first connection plate 21, and as the second sliding sleeve 20 slides on the second sliding rod 16 along the length direction of the second sliding rod 16, the rotational motion is converted into a linear motion, driving the second thread sleeve 19 to slide on the second screw rod 15. Under the connection of the first connection pins 22, the bearing plate 2 is driven to move accordingly. The transverse adjustment assembly includes a base 23 arranged on the upper surface of the frame 1. A second bearing seat 24 is centrally arranged on the upper surface of the base 23. Two second fixing seats 25 are symmetrically arranged on both sides of each second bearing seat 24. A third screw rod 26 is inserted into the second bearing seat 24. A third sliding rod 27 is inserted into two non-adjacent second fixing seats 25. The third sliding rod 27 is parallel to the third screw rod 26. A third motor 28 is further arranged on the frame 1. The power output end of the third motor 28 is connected to the third screw rod 26. A third thread sleeve 29 is sleeved on the third screw rod 26. A third sliding sleeve 30 is sleeved on the third sliding rod 27. A second connection plate 31 is arranged between the third thread sleeve 29 and the third sliding sleeve 30. Second connection pins 32 are arranged on the upper surfaces of the third thread sleeve 29 and the third sliding sleeve 30. The second connection pins 32 are connected to the moving plate 12. Through the rotation of the third screw rod 26, the third thread sleeve 29 is driven to rotate. Under the limitation of the second connection plate 31, the rotation of the third thread sleeve 29 is limited, and as the third sliding sleeve 30 slides on the third sliding rod 27, the rotational motion is converted into a linear motion, driving the third thread sleeve 29 to move on the third screw rod 26. Then, under the connection of the second connection pins 32, the moving plate 12 is driven to move, so that the actuator housing is adjusted longitudinally.

[0022] Further, the limiting component includes a support block 33 arranged on the upper surface of the carrier plate 2. A pull rod 34 is inserted into the support block 33. One end of the pull rod 34 is provided with a handle 35, and the other end of the pull rod 34 is provided with a baffle 36. An elastic member 37 is sleeved on the outer side of a section of the pull rod 34 between the baffle 36 and the support block 33. A limiting plate 38 is arranged on the side of the baffle 36 away from the pull rod 34. On the support block 33 and vertically below the pull rod 34, a strip plate 39 is also arranged. Both sides of the strip plate 39 are respectively connected to the baffle 36 and the pull rod 34 through support plates 40. When the handle 35 is pulled, the pull rod 34 moves in a direction away from the limiting plate 38, causing the baffle 36 to squeeze the elastic member 37. At this time, the limiting area formed between the two limiting plates 38 can be enlarged. After the actuator housing is placed in the limiting area, the handle 35 is released. The elastic force of the elastic member 37 acts on the baffle 36 in the reverse direction, pushing the limiting plate 38 to make the two limiting plates 38 approach each other, reducing the limiting area and clamping and fixing the actuator housing. A hole slot and a square slot for the pull rod 34 and the strip plate 39 are formed in the support block 33. When the pull rod 34 moves axially, the strip plate 39 supports the pull rod 34 through the support plate 40, so as to improve the moving strength of the pull rod 34 and prevent deviation.

[0023] A usage method of an actuator housing shaft hole opening device is as follows: S1. First, pull the two handles 35 to make the pull rod 34 move in the direction of the handle 35, drive the limiting plate 38 to move in the direction of the support block 33, and make the baffle 36 squeeze the elastic member 37, thereby enlarging the limiting area formed between the two limiting plates 38. Place the actuator housing to be drilled in the established area; S2. Start the third motor 28. The power output end of the third motor 28 drives the third screw rod 26 to rotate. Due to the internal thread of the third thread sleeve 29 being adapted to the outer thread of the third screw rod 26, as the third sliding sleeve 30 slides along the length direction of the third sliding rod 27 to limit the rotation of the third thread sleeve 29, the third thread sleeve 29 moves on the third screw rod 26, and then drives the movement of the moving plate 12 to adjust the lateral distance of the actuator housing; S3. Start the second motor 18. The power output end of the second motor 18 drives the second screw rod 15 to rotate. Due to the internal thread of the second thread sleeve 19 being adapted to the outer thread of the second screw rod 15, as the second sliding sleeve 20 slides along the length direction of the second sliding rod 16 to limit the rotation of the second sliding sleeve 20, the second thread sleeve 19 moves on the second screw rod 15. Under the connection of the first connecting pin 22, the carrier plate 2 follows the movement to adjust the longitudinal distance of the actuator housing; S4. After moving the actuator housing to the vertical lower side of the hole-opening drill 3, start the first motor 5. The power output end of the first motor 5 drives the first screw rod 6 to rotate. Due to the internal thread of the first thread sleeve 8 being adapted to the outer thread of the first screw rod 6, as the first sliding sleeve 9 slides along the length direction of the first sliding rod 7, rotational limitation is imposed on the first sliding sleeve 9, enabling the first thread sleeve 8 to move on the first screw rod 6, driving the lifting plate 10 to descend, and causing the hole-opening drill 3 to move to the position where the shaft hole of the actuator is to be opened, thus completing the hole-opening.
