Description

Technical Field

[0001] The present invention belongs to the technical field of automated detection, and in particular relates to a station switching and transfer mechanism of a detection and positioning device. Background Art

[0002] In the field of automated testing equipment, rapid multi-station switching and precise positioning of workpieces are key to improving inspection efficiency. Traditional indexing mechanisms often use fixed-angle positions or manual adjustment methods, making it difficult to dynamically adjust the workpiece angle during inspection, especially for complex workpieces that require multi-angle inspection. Simultaneously, with the rapid development of industrial automated testing technology, inspection and positioning devices have placed higher demands on the flexibility, accuracy, and stability of station switching.

[0003] The traditional workstation switching and transfer mechanism has the following main defects: First, the angle adjustment range is limited, and a single-axis rotation structure is mostly used, which makes it difficult to achieve continuous large angle adjustment from zero to ninety degrees. In addition, the adjustment process is easily disturbed by external forces, resulting in angle deviation and insufficient stability; second, the workpiece clamping mechanism is mostly a single-point or two-point contact design, and the uneven distribution of clamping force can easily cause deformation of the workpiece, especially affecting the measurement accuracy in precision inspection scenarios; third, the clamping and rotation functions are independent of each other. If the circumferential position of the workpiece needs to be adjusted in the clamped state, the workpiece must be released and then repositioned, which is cumbersome and inefficient.

[0004] To this end, we provide a station switching and transfer mechanism for a detection and positioning device to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a workstation switching and transfer mechanism for a detection and positioning device. Through the cooperation of an angle adjustment mechanism and a clamping mechanism, the problems of the workstation switching and transfer mechanism of the detection and positioning device in the prior art, such as a small angle adjustment range, a complex structure and poor clamping stability, are solved.

[0006] To solve the above technical problems, the present invention is implemented through the following technical solutions.

[0007] The present invention is a workstation switching and rotation mechanism of a detection and positioning device, comprising a box body, one side of the box body is fixedly connected to a mounting seat, the inner cavity of the mounting seat is rotatably connected to a rotating shaft through a bearing seat, the surface of the rotating shaft is fixedly connected to an adjusting plate, one side of the adjusting plate is fixedly connected to a support plate, and one side of the support plate is rotatably connected to a clamping disk through a bearing seat; an angle adjustment mechanism is provided in the inner cavity of the box body 1, the angle adjustment mechanism comprises a movable plate arranged in the inner cavity of the box body 1, a support rod movably connected to one side of the movable plate, a worm gear fixedly connected to the surface of the rotating shaft, and a worm meshing with the worm gear; a clamping mechanism is provided in the inner cavity of the clamping disk, the clamping mechanism comprises a first threaded rod rotatably connected to the inner cavity of the clamping disk through a bearing seat, a threaded sleeve sleeved on the surface of the first threaded rod, a limiting rod fixedly connected to the surface of the threaded sleeve, and a clamping block fixedly connected to the other end of the limiting rod.

[0008] The present invention is further configured such that a drive motor is fixedly connected to one side of the box body, and a synchronous belt is connected between the output shaft of the drive motor and the worm gear. The drive motor transmits rotational power to the worm gear through the synchronous belt, drives the worm gear to rotate, and then drives the rotating shaft to rotate through the worm gear. At the same time, the self-locking characteristics of the worm gear and worm gear ensure that the support plate can be suspended at any angle. The synchronous belt transmission has the characteristics of buffering and vibration absorption and smooth transmission, which can improve the accuracy and stability of angle adjustment.

[0009] The present invention is further configured such that the output shaft of the driving motor is fixedly connected to the first bevel gear, the surface of the first bevel gear is meshed with the second bevel gear, and the second threaded rod is fixedly connected at the axis of the second bevel gear. A threaded hole is opened on the top of the movable plate, and the movable plate is threadedly connected to the second threaded rod through the threaded hole. The driving motor simultaneously drives the first bevel gear to rotate, and the second bevel gear and the second threaded rod are driven to rotate through the meshing of the first bevel gear. The movable plate is threadedly matched with the second threaded rod through the threaded hole to realize reciprocating movement along the axial direction of the second threaded rod, thereby pushing the adjustment plate to rotate around the rotating shaft through the support rod, completing the active drive of the angle adjustment, and ensuring the stability of the support plate.

[0010] The present invention is further configured such that there are two adjustment plates, the worm gear is located between the two adjustment plates, the two adjustment plates are symmetrically distributed on both sides of the rotating shaft, and the worm gear is embedded in the middle, which can balance the radial force of the rotating shaft, avoid deformation caused by unilateral force, and improve structural rigidity and rotation accuracy.

[0011] The present invention is further configured such that a first tooth ring is provided in the inner cavity of the clamping disk, a bevel tooth ring is fixedly connected to the inner side of the first tooth ring, a third bevel gear is meshed with the surface of the bevel tooth ring, and the axis of the third bevel gear is fixedly connected to the surface of the first threaded rod. The first tooth ring drives the third bevel gear to rotate through the bevel tooth ring, and the third bevel gear drives the first threaded rod. The first threaded rod drives the clamping block to move through the threaded sleeve and the limit rod to clamp and fix the workpiece. The rotation of the first tooth ring engages or disengages with the driving gear, thereby switching the rotation mode or locking state of the clamping disk.

[0012] The present invention is further configured such that a sliding column is fixedly connected to one side of the first tooth ring, and a sliding groove adapted to the sliding column is provided in the inner cavity of the clamping disk. The cooperation between the sliding column and the sliding groove limits the moving direction of the first tooth ring (only along the axial direction), thereby avoiding its rotational deviation, ensuring that the bevel gear ring is always engaged with the third bevel gear, and ensuring the stability of the transmission.

[0013] The present invention is further configured such that a second toothed ring is fixedly connected to the surface of the clamping disk, and the second toothed ring can engage with the driving gear of the servo motor to realize the independent rotation function of the clamping disk (such as adjusting the circumferential position of the workpiece), thereby expanding the application scenarios of the mechanism.

[0014] The present invention is further configured such that an electric push rod is fixedly connected to one side of the support plate, a servo motor is fixedly connected to the output end of the electric push rod, and a driving gear is fixedly connected to the output shaft of the servo motor. The electric push rod can push the servo motor to move radially along the clamping disk, so that the driving gear selectively engages with the first tooth ring or the second tooth ring. When the driving gear engages with the first tooth ring, the servo motor can drive the first threaded rod to rotate, thereby realizing the movement of the clamping block. When it engages with the second tooth ring, the servo motor can drive the clamping disk to rotate as a whole, thereby realizing circumferential adjustment of the work station.

[0015] The present invention is further configured such that the number of the clamping blocks is three and they are arranged in a circular array, a buffer pad is provided on one side of the clamping block, and a limiting groove adapted to the limiting rod is provided on one side of the clamping disk. The three clamping blocks are distributed circumferentially, and can clamp the workpiece evenly at three points to avoid deformation due to single-point force. The buffer pad can absorb the impact during the clamping process and protect the surface of the workpiece. The limiting groove cooperates with the limiting rod to limit the rotational freedom of the threaded sleeve so that it only moves in the axial direction, thereby ensuring the accuracy of the telescopic action of the clamping block.

[0016] The present invention is further configured such that a control panel is provided on the front of the box, and the control panel integrates control buttons or a touch screen for the drive motor, electric push rod, and servo motor. The operator can set angle adjustment parameters, clamping pressure, etc. through the panel to realize automated and intelligent operation of the mechanism.

[0017] The present invention has the following beneficial effects.

[0018] 1. The present invention realizes continuous angle adjustment from zero to ninety degrees through the cooperation of worm gear transmission and double adjustment plate structure. The self-locking characteristic of the worm gear can effectively prevent angle deviation caused by external force interference. The synchronous belt transmission improves the adjustment accuracy. The first bevel gear on the output shaft of the drive motor engages with the second bevel gear to drive the second threaded rod to rotate. The movable plate is threadedly engaged with the second threaded rod through the top threaded hole and moves axially along the second threaded rod. The adjustment plate is pushed to rotate around the rotating shaft by the support rod, and the auxiliary rotating shaft completes the angle adjustment to ensure the reliability of the work station positioning.

[0019] 2. The present invention arranges three circular arrays of clamping blocks in the clamping disk, and cooperates with the buffer pad to achieve uniform force clamping of the workpiece at three points, avoiding deformation caused by single-point extrusion. The design of the limit groove and the limit rod limits the rotational freedom of the threaded sleeve, ensuring that the clamping block only moves in the axial direction, thereby improving the accuracy of the clamping action.

[0020] 3. The present invention supports adjustment of the circumferential position of the workpiece in the clamping state by switching engagement between the drive gear and the double-toothed ring (the first toothed ring and the second toothed ring). The electric push rod drives the servo motor to move radially, thereby realizing rapid switching between the clamping function and the rotation function, and expanding the application scenarios of the mechanism.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Example 1 See also Figures 1-8 The present invention is a workstation switching and rotating mechanism of a detection and positioning device, comprising a box body 1, a mounting seat 2 being fixedly connected to one side of the box body 1, a rotating shaft 3 being rotatably connected to the inner cavity of the mounting seat 2 through a bearing seat, an adjusting plate 4 being fixedly connected to the surface of the rotating shaft 3, a supporting plate 5 being fixedly connected to one side of the adjusting plate 4, a clamping disk 6 being rotatably connected to one side of the supporting plate 5 through a bearing seat, three clamping blocks 14 being arranged in a circular array, a buffer pad being provided on one side of the clamping block 14, a limiting groove 29 being provided on one side of the clamping disk 6 to match the limiting rod 13, and a control panel 30 being provided on the front of the box body 1.

[0034] Further supplement: Through the transmission of the worm gear 9 and the worm 10 and the cooperation of the double adjustment plate 4 structure, continuous angle adjustment from zero to ninety degrees is achieved. The synchronous belt 16 and the bevel gear transmission improve the transmission accuracy and angle adjustment error. The three clamping blocks 14 are distributed circumferentially, which can evenly clamp the workpiece at three points to avoid single-point force deformation. The buffer pad can absorb the impact during the clamping process and protect the surface of the workpiece. The limit groove 29 cooperates with the limit rod 13 to limit the rotational freedom of the threaded sleeve 12 so that it only moves axially, ensuring the accuracy of the telescopic action of the clamping block 14. The control panel 30 integrates the control buttons or touch screen of the drive motor 15, the electric push rod 26, and the servo motor 27. The operator can set the angle adjustment parameters, clamping pressure, etc. through the panel to realize the automation and intelligent operation of the mechanism.

[0035] Example 2 See also Figures 1-8 On the basis of Example 1, the inner cavity of the box body 1 is provided with an angle adjustment mechanism, which includes a movable plate 7 arranged in the inner cavity of the box body 1, a support rod 8 movably connected to one side of the movable plate 7, a worm gear 9 fixedly connected to the surface of the rotating shaft 3, and a worm 10 meshing with the worm gear 9. A driving motor 15 is fixedly connected to one side of the box body 1, and a synchronous belt 16 is connected between the output shaft of the driving motor 15 and the worm 10. The output shaft of the driving motor 15 is fixedly connected to a first bevel gear 17, and a second bevel gear 18 is meshed with the surface of the first bevel gear 17. A second threaded rod 19 is fixedly connected to the axis of the second bevel gear 18. A threaded hole 20 is opened on the top of the movable plate 7, and the movable plate 7 is threadedly connected to the second threaded rod 19 through the threaded hole 20. There are two adjusting plates 4, and the worm gear 9 is located between the two adjusting plates 4.

[0036] Further supplement; the driving motor 15 transmits the rotational power to the worm 10 through the synchronous belt 16, driving the worm 10 to rotate, and then drives the rotating shaft 3 to rotate through the worm gear 9. At the same time, the self-locking characteristics of the worm gear 9 and the worm 10 ensure that the support plate 5 can hover at any angle. The synchronous belt 16 transmission has the characteristics of buffering and vibration absorption and smooth transmission, which can improve the accuracy and stability of angle adjustment. The driving motor 15 simultaneously drives the first bevel gear 17 to rotate, and drives the second bevel gear 18 and the second threaded rod 19 to rotate through the engagement of the first bevel gear 17. The movable plate 7 is threadedly matched with the second threaded rod 19 through the threaded hole 20 to achieve reciprocating movement along the axial direction of the second threaded rod 19, thereby pushing the adjustment plate 4 to rotate around the rotating shaft 3 through the support rod 8, completing the active drive of the angle adjustment, and ensuring the stability of the support plate 5. The two adjustment plates 4 are symmetrically distributed on both sides of the rotating shaft 3, and the worm gear 9 is embedded in the middle, which can balance the radial force of the rotating shaft 3, avoid deformation caused by unilateral force, and improve structural rigidity and rotation accuracy.

[0037] Example 3 See also Figures 1-8On the basis of Examples 1 and 2, a clamping mechanism is provided in the inner cavity of the clamping disk 6, the clamping mechanism includes a first threaded rod 11 rotatably connected to the inner cavity of the clamping disk 6 through a bearing seat, a threaded sleeve 12 sleeved on the surface of the first threaded rod 11, a limiting rod 13 fixedly connected to the surface of the threaded sleeve 12, and a clamping block 14 fixedly connected to the other end of the limiting rod 13; a first toothed ring 21 is provided in the inner cavity of the clamping disk 6, a bevel gear ring 22 is fixedly connected to the inner side of the first toothed ring 21, a third bevel gear 23 is meshed on the surface of the bevel gear ring 22, and the axis of the third bevel gear 23 is fixedly connected to the surface of the first threaded rod 11, a slide column 24 is fixedly connected to one side of the first toothed ring 21, a slide groove adapted to the slide column 24 is opened in the inner cavity of the clamping disk 6, a second toothed ring 25 is fixedly connected to the surface of the clamping disk 6, and an electric push rod 26 is fixedly connected to one side of the support plate 5, and the output end of the electric push rod 26 is fixedly connected to the servo motor 27, and the output shaft of the servo motor 27 is fixedly connected to the driving gear 28.

[0038] Further supplement; the first toothed ring 21 drives the third bevel gear 23 to rotate through the bevel gear ring 22, and the third bevel gear 23 drives the first threaded rod 11, and the first threaded rod 11 drives the clamping block 14 to move through the threaded sleeve 12 and the limit rod 13 to clamp and fix the workpiece. The rotation of the first toothed ring 21 engages or disengages with the driving gear 28, thereby switching the rotation mode or locking state of the clamping disk 6. The cooperation of the slide post 24 and the slide groove limits the movement direction of the first toothed ring 21 (only in the axial direction), avoiding its rotational deviation, ensuring that the bevel gear ring 22 is always engaged with the third bevel gear 23, ensuring the stability of the transmission, and the first toothed ring 21 is engaged with or disengaged from the driving gear 28. The two-toothed ring 25 can be engaged with the driving gear 28 of the servo motor 27 to realize the independent rotation function of the clamping disk 6 (such as adjusting the circumferential position of the workpiece), expanding the application scenario of the mechanism. The electric push rod 26 can push the servo motor 27 to move radially along the clamping disk 6, so that the driving gear 28 selectively engages with the first toothed ring 21 or the second toothed ring 25. When the driving gear 28 engages with the first toothed ring 21, the servo motor 27 can drive the first threaded rod 11 to rotate to realize the movement of the clamping block 14. When engaged with the second toothed ring 25, the servo motor 27 can drive the clamping disk 6 to rotate as a whole to realize circumferential adjustment of the work station.

[0039] The working principle of the present invention is: when it is necessary to clamp the workpiece, the electric push rod 26 drives the driving gear 28 to engage with the first tooth ring 21, then the servo motor 27 is started, the driving gear 28 rotates, and drives the first tooth ring 21 to move axially, and drives the first threaded rod 11 to rotate through the bevel gear ring 22 and the third bevel gear 23, and the threaded sleeve 12 moves along the first threaded rod 11 toward the center of the clamping disk 6, and the limit rod 13 drives the clamping block 14 to move, and finally the three clamping blocks 14 cooperate with the buffer pad to clamp the workpiece.

[0040] When the work position needs to be adjusted from zero to ninety degrees, the operator starts the drive motor 15 through the control panel 30. The drive motor 15 drives the worm 10 to rotate through the synchronous belt 16. The worm 10 engages with the worm wheel 9, driving the rotating shaft 3 to rotate counterclockwise. Since the adjustment plate 4 is fixedly connected to the rotating shaft 3, the support plate 5 and the clamping plate 6 rotate synchronously with the rotating shaft 3 until the target angle is reached. The drive motor 15 simultaneously drives the first bevel gear 17 to rotate, and the engagement of the first bevel gear 17 drives the second bevel gear 18 and the second threaded rod 19 to rotate. The movable plate 7 is threadedly engaged with the second threaded rod 19 through the threaded hole 20, achieving reciprocating movement along the axial direction of the second threaded rod 19, thereby pushing the adjustment plate 4 to rotate around the rotating shaft 3 through the support rod 8, completing the active drive of the angle adjustment and ensuring the stability of the support plate 5. The self-locking characteristics of the worm wheel 9 and the worm 10 can maintain the angle stability and avoid deviation caused by external interference.

[0041] If the circumferential position of the workpiece needs to be adjusted in the clamping state, the electric push rod 26 continues to push the servo motor 27, so that the drive gear 28 disengages from the first tooth ring 21 and engages with the second tooth ring 25. The servo motor 27 rotates, and the drive gear 28 drives the second tooth ring 25 to rotate, and the clamping disk 6 rotates as a whole to adjust the circumferential position of the workpiece. After the adjustment is completed, the servo motor 27 stops, the electric push rod 26 resets, and the drive gear 28 re-engages with the first tooth ring 21 to lock the clamping disk 6.

[0042] This mechanism integrates clamping, angular tilting, and circumferential rotation through electromechanical coordinated control, significantly improving detection efficiency and positioning accuracy.

[0043] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
