Description

Technical Field

[0001] The invention relates to the technical field of hinge beam processing, and more specifically, to a hinge beam processing rotating device for a six-sided top press. Background Art

[0002] The hinge beam, a main component of the six-sided top press of artificial diamond synthesis equipment, needs to have its ears processed during the process. Since there are 4 groups of 10 ears of the hinge beam that need to be processed, and the 10 ears are unevenly distributed on the outside of the hinge beam, the hinge beam needs to change its position during processing so that the ears are in the processing station. However, each group of ears of the hinge beam needs to be flipped and aligned once during the processing, so a rotating device is required.

[0003] For example, the existing patent CN218487746U was retrieved, which discloses an automatic displacement device for processing the hinge beam of a six-sided top press. The prior art drives the hinge beam to rotate slowly through a rotating mechanism and a positioning mechanism. When it rotates to a specified angle, the positioning mechanism sends a pulse signal to the programmable controller, and the programmable controller controls the rotating mechanism to stop, so that the hinge beam stops at the specified position, thereby realizing automatic rotation displacement and fixed position during hinge beam processing.

[0004] However, the prior art has the following problems during use: in order to facilitate the rotation of the hinge beam in the prior art, the hinge beam is suspended in the air and its rotation is controlled. During the processing, the weight of the hinge beam is completely pressed on the rotating mechanism. At the same time, the weight of the existing hinge beam is greater than 5 tons, which causes the rotating mechanism to bear greater pressure. During the processing, the hinge beam will inevitably deviate, affecting the stability of the hinge beam processing and also placing a greater burden on the rotating mechanism.

DETAILED DESCRIPTION

[0018] See also Figure 1-7 , the present invention provides the following technical solutions: The invention relates to a rotating device for processing hinge beams of a six-sided top press, comprising a U-shaped base 1 and a hinge beam 2. The hinge beam 2 is arranged between two vertical plates of the U-shaped base 1 for processing. A bearing plate 3 for supporting the hinge beam 2 is arranged on the upper surface of the horizontal plate of the U-shaped base 1. A lifting cavity is provided in the horizontal plate of the U-shaped base 1. A lifting rod 4 is arranged on the lower surface of the bearing plate 3. The lower end of the lifting rod 4 slides through the lifting cavity of the U-shaped base 1. A threaded rod 5 is rotatably connected to the inner wall of the rear side of the lifting cavity. A threaded sleeve 6 is arranged on the outer surface of the threaded rod 5. A first rotating plate 7 is hinged between the outer surface of the threaded sleeve 6 and the lower end of the lifting rod 4. A driving shaft 8 is arranged at the front end of the threaded rod 5. The front end of the driving shaft 8 rotates and passes through the front surface of the U-shaped base 1. Therefore, the driving shaft 8 can be driven by twisting the driving shaft 8. The front end of the movable shaft 8 causes the driving shaft 8 to drive the threaded rod 5 to rotate, so that the threaded sleeve 6 moves forward or backward on the outer surface of the threaded rod 5. When the threaded sleeve 6 moves toward the rear side, the threaded sleeve 6 will squeeze the first rotating plate 7, so that the first rotating plate 7 pushes the lifting rod 4 to move upward. At this time, the lifting rod 4 simultaneously pushes the bearing plate 3 and the hinge beam 2 to move upward. The above structure can support the bottom of the hinge beam 2, and the problem of the hinge beam 2 moving downward during the processing steps such as drilling holes in the hinge beam 2 is avoided as much as possible, thereby ensuring the stability of the hinge beam 2 during processing. When the threaded sleeve 6 moves to the front side, the threaded sleeve 6 will form a pulling force on the first rotating plate 7, so that the first rotating plate 7 pulls the lifting rod 4 to move downward. At this time, the bearing plate 3 moves downward synchronously.

[0019] A rotating motor 9 is provided on the front surface of the U-shaped base 1, and a top cavity 24 is opened in the front vertical plate of the U-shaped base 1. The rear end of the output shaft of the rotating motor 9 rotates and passes through the top cavity 24. A transmission shaft 12 is provided at the rear end of the output shaft of the rotating motor 9, and a rotating shaft 10 is provided at the rear end of the transmission shaft 12. The rear end of the rotating shaft 10 movably passes through the vertical plate of the U-shaped base 1. A clamping structure for controlling the displacement of the rotating shaft 10 is provided on the U-shaped base 1. A rotating plate 11 is rotatably connected to the front surface of the vertical plate on the rear side of the U-shaped base 1. The rotating plate 11 and the rotating shaft 10 are at the same horizontal position. When the bearing plate 3 pushes the hinge beam 2 upward to the specified position, the clamping structure controls the rotating shaft 10 to move backward, thereby tightening the hinge beam 2 between the rotating shaft 10 and the rotating plate 11. When the hinge beam 2 needs to be turned over and rotated after processing, the rotating motor 9 is started, so that the rotating shaft 10 can drive the hinge beam 2 to rotate between the rotating shaft 10 and the rotating plate 11, thereby achieving the purpose of controlling the reversing of the hinge beam 2.

[0020] A friction plate is provided at the rear end of the rotating shaft 10, which increases the friction force of the contact surface between the rotating shaft 10 and the hinge beam 2, and avoids the problem of slipping when the rotating shaft 10 drives the hinge beam 2 to rotate.

[0021] The clamping mechanism includes an electric push rod 45, which is arranged on the right side surface of the vertical plate on the front side of the U-shaped base 1. A control chamber 41 is opened in the vertical plate on the front side of the U-shaped base 1. The left end of the telescopic rod of the electric push rod 45 slides into the control chamber 41. A trigger rod 46 is arranged at one end of the telescopic rod of the electric push rod 45 located in the control chamber 41. The left end of the trigger rod 46 slides into the top chamber 24. A third rotating plate 49 is hinged between the left end of the trigger rod 46 and the outer surface of the rotating shaft 10. An extension groove 13 is opened on the side surface of the rotating shaft 10 facing the transmission shaft 12. The rear end of the transmission shaft 12 extends into the extension groove 13 and slides in the extension groove 13. A limiting slider is arranged on the outer surface of the transmission shaft 12 14, a limiting slide groove 15 extending from the front surface of the rotating shaft 10 is opened on the inner wall of the extension groove 13, and the limiting slider 14 slides in the limiting slide groove 15. When the rotating shaft 10 needs to press against the hinge beam 2, the telescopic rod of the electric push rod 45 pushes the trigger rod 46 to move to the left. At this time, the trigger rod 46 will form a thrust on the third rotating plate 49, so that the third rotating plate 49 pushes the rotating shaft 10 to move backward, so that the hinge beam 2 can be clamped between the rotating shaft 10 and the rotating plate 11. At the same time, when the rotating shaft 10 is in the sliding process, the limiting slider 14 slides in the limiting slide groove 15. When the transmission shaft 12 rotates, the rotating shaft 10 is restricted by the limiting slider 14, and thus it will rotate synchronously with the transmission shaft 12.

[0022] The outer surface of the drive shaft 8 is sleeved with a worm wheel 16, and the outer surface of the worm wheel 16 is meshedly connected with a movable worm 17, and the upper end of the worm 17 is provided with a square rod 22, and the upper end of the square rod 22 is provided with a movable column 21, and the upper end of the movable column 21 is rotated to penetrate into the top cavity 24, and the upper end of the movable column 21 is provided with a twisted rod 27, and the upper surface of the movable column 21 is provided with a twisted groove adapted to the twisted rod 27, and the upper end of the twisted rod 27 is rotatably connected with an extrusion plate 26, and a movable sleeve is provided between the lower surface of the extrusion plate 26 and the bottom wall of the top cavity 24. The outer surface of the transmission shaft 12 is provided with four extrusion protrusions 25 arranged in a circumferential array. The shape of the extrusion protrusions 25 is an isosceles triangle. The outer surface of the extrusion protrusions 25 contacts the upper surface of the extrusion plate 26. When the hinge beam 2 is driven to rotate, the transmission shaft 12 synchronously drives the extrusion protrusions 25 to rotate, so that the extrusion protrusions 25 form a downward thrust on the extrusion plate 26, and the first spring 28 is stressed and contracts. At this time, the twist rod 27 moves downward synchronously with the extrusion plate 26. Due to the characteristics of the twist rod 27, the twist rod 27 can drive the movable The movable column 21 rotates, thereby synchronously driving the worm 17 to rotate. At this time, the drive shaft 8 rotates under the meshing of the worm 17 with the transmission worm wheel 16, so that the threaded sleeve 6 can be controlled to move forward. At this time, the bearing plate 3 moves downward. Since the hinge beam 2 is tightened by the rotating shaft 10, there will be no problem of downward movement. Therefore, the bearing plate 3 will not affect the rotation of the hinge beam 2. When the hinge beam 2 rotates at an angle of more than 45 degrees, the lowest end of the hinge beam 2 begins to move upward, and at the same time, the extrusion protrusion 25 no longer contacts the extrusion plate 26, so that the extrusion plate 26 is pushed by the first spring 28. The hinge beam 2 is moved downward and upward, thereby driving the movable column 21 to reverse. At this time, the threaded rod 5 is reversed synchronously, so the threaded sleeve 6 is displaced to the rear side and restored to the initial position, so that the bearing plate 3 is displaced upward. The above-mentioned structure can automatically control the bearing plate 3 to move downward when the hinge beam 2 rotates, and will not cause any obstruction to the rotation of the hinge beam 2. At the same time, after the hinge beam 2 has rotated, the bearing plate 3 can be against the bottom of the hinge beam 2 again, thereby ensuring the stability of the hinge beam 2 after the reversing process. At the same time, the structure does not require manual control, which greatly improves the efficiency and speed of processing the hinge beam 2.

[0023] A T-shaped slide groove 19 is provided on the bottom wall of the lifting chamber, and a T-shaped slider 18 is slidably connected in the T-shaped slide groove 19. The lower end of the worm 17 is rotatably connected to the upper surface of the T-shaped slider 18. A reset chamber 29 is provided in the vertical plate on the front side of the U-shaped base 1. The bottom wall of the reset chamber 29 is slidably connected with a first rack 31. A bottom pulling rod 30 is provided on the left side surface of the first rack 31. The left end of the bottom pulling rod 30 slides into the lifting chamber, and the left end of the bottom pulling rod 30 is rotatably sleeved on the outer surface of the top of the worm 17. A second tension spring 32 movably sleeved on the outer surface of the bottom pulling rod 30 is provided between the first rack 31 and the left inner wall of the reset chamber 29. When the second spring 32 is not affected by the tension, the second tension spring 32 will form a pulling force on the first rack 31, so that the first rack 31 is close to the side of the lifting chamber. Therefore, the bottom pulling rod 30 will form a thrust on the worm 17, so that the initial position of the worm 17 is meshed with the worm wheel 16.

[0024] A docking groove 20 is provided on the upper surface of the worm 17, and the shape of the docking groove 20 is flower-shaped. A docking block 23 adapted to the docking groove 20 is provided on the lower surface of the square rod 22. When the docking block 23 extends into the docking groove 20, the rotation of the square rod 22 can drive the worm 17 to rotate. A square groove adapted to the outer surface of the square rod 22 is provided on the lower surface of the movable column 21. The upper end of the square rod 22 extends into the square groove and slides in the square groove. A rotating ring 37 is rotatably sleeved on the outer surface of the square rod 22. A second rotating plate 38 is hingedly connected to the outer surface of the rotating ring 37. A push rod 35 is hingedly connected to the other side of the second rotating plate 38. The other end of the push rod 35 slides through the reset chamber 29. One end of the push rod 35 located in the reset chamber 29 is provided with a second rack 34 meshingly connected to the upper side of the first gear 33. No teeth are provided on the left side of the lower surface of the second rack 34. The left side surface of the second rack 34 is connected to the inner wall of the reset chamber 29. A third tension spring 36 movably sleeved on the outer surface of the push rod 35 is provided, and the strength of the third tension spring 36 is greater than the strength of the second tension spring 32. When the third tension spring 36 is not affected by the tension force, the third tension spring 36 pulls the second rack 34 to be located on the side close to the lifting chamber. At this time, the push rod 35 forms an extrusion effect on the second rotating plate 38, so that the second rotating plate 38 pushes the square rod 22 to move upward and shrink into the square groove. At the same time, the docking block 23 moves out of the docking groove 20. Since the strength of the third tension spring 36 is greater than the strength of the second tension spring 32, when the second rack 34 is displaced on the side close to the lifting chamber, under the action of the first gear 33, the meshing drives the first rack 31 to be located on the side away from the lifting chamber. At this time, the worm 17 is not meshed with the worm wheel 16. Through the above structure, the worm wheel and worm will not affect the rotation of the threaded rod 5 during the process of the bearing plate 3 pushing the hinge beam 2 upward, thereby ensuring the stability of the device when in use.

[0025] A connecting slot 39 communicating with the control chamber 41 is provided on the top wall of the reset chamber 29, a connecting plate 40 is provided on the upper surface of the second rack 34, the upper side of the connecting plate 40 extends into the control chamber 41 through the connecting slot 39 and slides in the connecting slot 39, a third rack 42 is provided on the upper side of the connecting plate 40, a second gear 43 meshingly connected with the third rack 42 is rotatably connected on the bottom wall of the control chamber 41, a fourth rack 44 sliding on the bottom wall of the control chamber 41 is meshingly connected to the rear side of the second gear 43, a first baffle 47 is provided on the rear side surface of the fourth rack 44, a second baffle 48 contacting with the first baffle 47 is provided on the outer surface of the trigger rod 46, when the electric push rod 45 pushes the trigger rod 4 During the displacement to the left, the second baffle plate 48 contacts the first baffle plate 47, so the trigger rod 46 can synchronously drive the fourth rack 44 to move to the left. At this time, the meshing of the fourth rack 44 drives the second gear 43 to rotate counterclockwise, and the third rack 42 moves to the right driven by the second gear 43, and the second rack 34 moves to the right synchronously driven by the connecting plate 40, so the push rod 35 forms a downward pulling force on the square rod 22, and the first rack 31 moves to the left driven by the first gear 33, so that the bottom pulling rod 30 pushes the worm 17 to move to the left. Since there is no tooth on the left side of the lower surface of the second rack 34, when the second rack 34 moves to the left side of the first gear 33, the second rack 34 cannot limit the first rack 31, so the first rack 31 quickly moves to the initial position under the pull of the second tension spring 32, and the worm 17 is meshed with the worm wheel 16. Since the second rack 34 is still moving to the right, the square rod 22 continues to move downward. When the second rack 34 moves to the rightmost side, the square rod 22 moves down to the lowest side, and the docking block 23 is inserted into the docking groove 20, thereby completing the driving of the threaded rod 5. When the rotating shaft 10 no longer presses the hinge beam 2, the electric push rod 45 pulls the trigger rod 46 to move to the right, so it cannot form a limiting effect on the second rack 34. At this time, the second rack 34 is pulled to the left by the third tension spring 36. The square rod 22 moves upward at the same time. Since there is no tooth on the left side of the lower surface of the second rack 34, the second rack 34 cannot drive the first gear 33 to rotate during the displacement to the left. When the docking block 23 moves out of the docking groove 20, the teeth on the lower side of the second rack 34 mesh with the first gear 33, so that the first gear 33 pulls the first rack 31 to move to the right, so that the worm 17 is no longer meshed with the worm wheel 16. Through the above structure, when the rotating shaft 10 is pressed against the hinge beam 2, the worm 17 is automatically controlled to mesh with the worm wheel 16. When the rotating shaft 10 is no longer pressed against the hinge beam 2, the worm 17 is automatically controlled to separate from the worm wheel 16, which will not affect the normal operation of the lifting structure of the bearing plate 3.

[0026] In the present invention, the front end of the drive shaft 8 can be connected to a motor without a self-locking function. When the motor stops running, the output shaft of the motor cannot restrict the drive shaft 8, thereby not affecting the operation of the above structure. In addition, the setting of the motor reduces the working force when lifting the hinge beam 2.

[0027] The working principle of the hinge beam processing rotation device provided by the present invention is as follows: the first step is to place the hinge beam 2 on the bearing plate 3 and control the driving shaft 8 to rotate so that the threaded sleeve 6 on the threaded rod 5 is displaced to the rear side, so that the threaded sleeve 6 will squeeze the first rotating plate 7, so that the first rotating plate 7 pushes the lifting rod 4 to move upward, and then the lifting rod 4 simultaneously pushes the bearing plate 3 and the hinge beam 2 to move upward until the hinge beam 2 moves to a specified height, and then the electric push rod 45 telescopic rod pushes the trigger rod 46 to move to the left side, and then the trigger rod 46 will form a thrust on the third rotating plate 49, so that the third rotating plate 49 pushes the rotating shaft 10 to move to the rear side, so that the hinge beam 2 can be clamped between the rotating shaft 10 and the rotating plate 11; In the second step, when the trigger rod 46 moves to the left, the second baffle plate 48 contacts the first baffle plate 47, so the trigger rod 46 can synchronously drive the fourth rack 44 to move to the left. At this time, the fourth rack 44 engages and drives the second gear 43 to rotate counterclockwise, and the third rack 42 moves to the right driven by the second gear 43, and the second rack 34 moves to the right synchronously driven by the connecting plate 40, so the push rod 35 forms a downward pulling force on the square rod 22, and the first rack 31 moves to the left driven by the first gear 33, so that the bottom pulling rod 30 pushes the worm. The rod 17 moves to the left. Since there is no tooth on the left side of the lower surface of the second rack 34, when the second rack 34 moves to the upper side of the first gear 33, the second rack 34 cannot limit the first rack 31. Therefore, under the pull of the second tension spring 32, the first rack 31 quickly moves to the initial position. At the same time, the worm 17 is meshed with the worm wheel 16. Since the second rack 34 is still moving to the right, the square rod 22 continues to move downward. When the second rack 34 moves to the far right, the square rod 22 moves down to the lowest side, and the docking block 23 is inserted into the docking groove 20. The third step, when one side of the hinge beam 2 is processed and needs to be changed, the rotating motor 9 is started, so that the rotating shaft 10 can drive the hinge beam 2 to rotate between the rotating shaft 10 and the rotating plate 11. When driving the hinge beam 2 to rotate, the transmission shaft 12 synchronously drives the extrusion protrusion 25 to rotate, so that the extrusion protrusion 25 forms a downward thrust on the extrusion plate 26, and the first spring 28 is stressed and contracts. At this time, the twist rod 27 moves downward synchronously with the extrusion plate 26. Due to the characteristics of the twist rod 27, the movable column 21 can be driven to rotate when the twist rod 27 moves downward, thereby synchronously driving the worm 17 to rotate. At this time, the drive shaft 8 rotates under the meshing of the worm 17 with the transmission worm wheel 16, thereby controlling the threaded sleeve 6 to move forward, and the bearing plate 3 is moved downward. Since the hinge beam 2 is pressed by the rotating shaft 10, there will be no problem of downward movement. Therefore, the bearing plate 3 will not affect the rotation of the hinge beam 2. When the hinge beam 2 rotates at an angle of more than 45 degrees, the lowest end of the hinge beam 2 begins to move upward. At the same time, the extrusion protrusion 25 is no longer in contact with the extrusion plate 26, so that the extrusion plate 26 moves upward under the push of the first spring 28, thereby driving the movable column 21 to reverse. At this time, the threaded rod 5 is reversed synchronously, so the threaded sleeve 6 moves backward and returns to its initial position, thereby causing the bearing plate 3 to move upward. Through the above-mentioned structural structure, the bearing plate 3 can be automatically controlled to move downward when the hinge beam 2 rotates, and the rotation of the hinge beam 2 will not be blocked. At the same time, after the hinge beam 2 rotates, the bearing plate 3 can be pressed against the bottom of the hinge beam 2 again.
