Description

Technical Field

[0001] This utility model relates to the field of inspection tool technology, and in particular to a flipping mechanism and inspection tool. Background Technology

[0002] Currently, in inspection fixtures, when it is necessary to flip a detection unit or fixture, a flipping mechanism is often set up for the detection unit or fixture.

[0003] In existing technologies, flipping mechanisms generally employ a single-axis hinge structure or a dual-axis hinge structure.

[0004] However, the hinge point of a single-axis hinge structure is a static rotation fulcrum. The detection unit or fixture is driven to rotate around this static rotation fulcrum by a drive device. Its rotation angle range is relatively wide, but the hinge point is subject to large forces, making it prone to wear and deformation, resulting in low reliability and deviation of the rotation movement. This can cause significant errors when applied to inspection fixtures. The hinge point of a dual-axis hinge structure consists of a static rotation fulcrum and a dynamic rotation hinge point. The detection unit or fixture is driven to rotate around the static rotation fulcrum by a drive device acting on the dynamic rotation hinge point. However, this structure has a dead point position, resulting in a narrow rotation angle range and poor adaptability.

[0005] Therefore, given the current problems of large positional errors and poor adaptability of the flipping mechanism, it is urgent to develop a new machine or a new technology to solve these problems. Utility Model Content

[0006] The purpose of this utility model is to provide a flipping mechanism and inspection fixture, which aims to solve or at least partially solve the shortcomings of the above-mentioned background technology. It has a simple structure, stable operation, high reliability, and good adaptability.

[0007] This utility model provides a flipping mechanism, including a base plate, two flipping plates, and a driving device. One end of the flipping plate is rotatably connected to the base plate, and the other end of the flipping plate is connected to a fixed seat for mounting a detection unit or fixture. The driving device is inclinedly mounted on the base plate and located between the two flipping plates, with an inclination angle θ of 45° to 65°. The driving device and the fixed seat are connected by a multi-link structure, which includes a first link fixedly connected to the movable end of the driving device, a second link fixedly connected to the fixed seat, and a transmission rod with its two ends hinged to the first link and the second link, respectively. The movable end of the driving device can extend and retract to drive the multi-link structure to rotate the fixed seat downwards or upwards.

[0008] Furthermore, the angle β between the extension direction of the moving end of the drive device and the extension direction of the transmission rod is less than 180°.

[0009] Furthermore, the first link has a first clamping part, which is hinged to the first end of the transmission rod; the second link has a second clamping part, which is hinged to the second end of the transmission rod.

[0010] Furthermore, the first clamping part is a pair of first clamping arms, with the first end of the transmission rod clamped between the pair of first clamping arms; the second clamping part is a pair of second clamping arms, with the second end of the transmission rod clamped between the pair of second clamping arms.

[0011] Furthermore, the drive unit is inclinedly mounted on the base plate via a support frame, which includes a support plate and a fixing plate. The fixing plate is inclinedly mounted on the support plate, and the drive unit is fixed on the fixing plate.

[0012] Furthermore, the tilt angle of the fixed plate is consistent with the tilt angle θ.

[0013] Furthermore, a mounting base that detachably engages with the flip plate is provided on the base plate, and the mounting base and the flip plate are rotatably connected via a pivot.

[0014] Furthermore, the mounting base is recessed with a relief groove to allow the rotating plate to rotate, and the rotating shaft passes through the outer wall of the mounting base and the rotating plate.

[0015] Furthermore, the flip plate has a chamfered structure at the end that is rotatably connected to the rotating shaft. The chamfered structure is used to prevent the flip plate from interfering with the mounting base when it rotates.

[0016] This utility model also provides a gauge, including the above-mentioned flipping mechanism, and several detection units are installed on the fixed base of the flipping mechanism.

[0017] This utility model provides a flipping mechanism that, through the cooperation of a drive device, a base plate, a flipping plate, a multi-link structure, and a fixed seat, enables the fixed seat to flip along with the flipping plate. The multi-link structure allows the first and second hinge points to share the stress with the static rotation fulcrum, dispersing stress and preventing wear or deformation at the static rotation fulcrum, thereby improving reliability and preventing the flipping plate and fixed seat from shifting during the flipping motion. Simultaneously, the swinging of the transmission rod ensures that the movement trajectory of the drive device's moving end does not interfere with the flipping trajectory of the flipping plate, avoiding dead points and thus expanding the range of the flipping angle α, improving the adaptability of the flipping mechanism. By placing the drive device between the two flipping plates, the stability of the flipping plate's operation is improved. By setting the tilt angle θ to 45°~65°, the reliability of the flipping mechanism is ensured, flipping motion deviation is avoided, and the drive device can effectively drive the flipping plate and fixed seat. Therefore, this flipping mechanism has a simple structure, stable operation, high reliability, and good adaptability. Attached Figure Description

[0035] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6 The present invention provides a flipping mechanism, including a base plate 10, two flipping plates 20 and a driving device 30. One end of the flipping plate 20 is rotatably connected to the base plate 10 to form a static rotation fulcrum 113. The other end of the flipping plate 20 is connected to a fixing seat 50 for installing a detection unit or a fixture. The driving device 30 is inclinedly arranged on the base plate 10 and located between the two flipping plates 20.

[0036] The drive unit 30 is connected to the fixed base 50 via a multi-link structure 40. The multi-link structure 40 includes a first link 41 fixedly connected to the movable end 31 of the drive unit 30, a second link 43 fixedly connected to the fixed base 50, and a transmission rod 42 with its two ends hinged to the first link 41 and the second link 43, respectively. The two ends of the transmission rod 42 form a first hinge point 48 and a second hinge point 49 with the first link 41 and the second link 43, respectively. The movable end 31 of the drive unit 30 can extend and retract to drive the multi-link structure 40 to rotate the fixed base 50 downwards or upwards.

[0037] The tilt angle θ of the drive device 30 is between 45° and 65°. It is understood that if the tilt angle θ is too large, the stress on the first hinge point 48 will be excessive, easily causing wear or even deformation at the connection between the first connecting rod 41 and the transmission rod 42, resulting in lower reliability and causing the tilting motion of the flipping plate 20 to deviate, leading to significant errors when applied to the inspection fixture. If the tilt angle θ is too small, the effective driving force of the drive device 30 will be reduced, making it difficult to rotate the flipping plate 20 and the fixed base 50. Furthermore, it will result in insufficient clearance between the flipping plate 20 and the second connecting rod 43, easily causing jamming or excessive wear. Through multiple tests, the tilt angle θ, within the range of 40° to 75°, can meet the requirements of reliability and effective driving force. Preferably, the tilt angle θ is between 45° and 65°. Those skilled in the art can specifically set the tilt angle θ to 45°, 50°, 55°, 60°, 65°, etc., and no unique limitation is made here.

[0038] More specifically, a flip angle α is formed between the flip plate 20 and the base plate 10; in the initial state, the movable end 31 of the drive device 30 is in a naturally extended state, and the flip plate 20 is in contact with the base plate 10, and the flip angle α is 0°; when flipping, the movable end 31 of the drive device 30 retracts and pulls the fixed base 50 upward through the multi-link structure 40, and the maximum value of the flip angle α is 35°.

[0039] As described above, the present invention provides a flipping mechanism that, through the cooperation of a drive device 30, a base plate 10, a flipping plate 20, a multi-link structure 40, and a fixed seat 50, enables the fixed seat 50 to flip along with the flipping plate 20. By providing the multi-link structure 40, the first hinge point 48 and the second hinge point 49 can share the stress with the static rotation fulcrum 113 to disperse the stress, preventing wear or deformation at the static rotation fulcrum 113, thereby improving its reliability and preventing the flipping plate 20 and the fixed seat 50 from shifting during the flipping motion. Simultaneously, through… The swinging motion of the transmission rod 42 ensures that the movement trajectory of the movable end 31 of the drive device 30 does not interfere with the flipping trajectory of the flipping plate 20, avoiding dead points and thus expanding the range of the flipping angle α, thereby improving the adaptability of the flipping mechanism. By placing the drive device 30 between the two flipping plates 20, the stability of the flipping plate 20's operation is improved. By setting the tilt angle θ to 45°~65°, the reliability of the flipping mechanism is ensured, the flipping motion deviation is avoided, and the drive device 30 can effectively drive the flipping plate 20 and the fixed base 50. Therefore, this flipping mechanism has a simple structure, stable operation, high reliability, and good adaptability.

[0040] Please see Figure 5 In the initial state, the angle β between the extension direction of the movable end 31 of the drive device 30 and the extension direction of the transmission rod 42 is less than 180°, ensuring that the movable end 31 can pull the transmission rod 42 through the first connecting rod 41 and make the transmission rod 42 swing smoothly, thereby realizing smoother rotation of the flip plate 20 and the fixed seat 50.

[0041] Please see Figure 2 , Figure 3 and Figure 6 The first connecting rod 41 has a first clamping part 44, which is hinged to the first end 421 of the transmission rod 42 via a first pin 46. The second connecting rod 43 has a second clamping part 45, which is hinged to the second end 422 of the transmission rod 42 via a second pin 47. The first connecting rod 41 and the transmission rod 42, and the second connecting rod 43 and the transmission rod 42, are respectively rotatable relative to each other. The swing of the transmission rod 42 ensures that the movement trajectory of the movable end 31 of the drive device 30 does not interfere with the rotation trajectory of the fixed seat 50, avoiding dead point positions, expanding the range of the flip angle α, and improving the adaptability of the flipping mechanism.

[0042] Furthermore, the first clamping part 44 consists of a pair of first clamping arms 441, with the first end 421 of the transmission rod 42 clamped between the pair of first clamping arms 441, and the first pin 46 passing through the first clamping arms 441 and the transmission rod 42; the second clamping part 45 consists of a pair of second clamping arms 451, with the second end 422 of the transmission rod 42 clamped between the pair of second clamping arms 451, and the second pin 47 passing through the second clamping arms 451 and the transmission rod 42. The cooperation between the first clamping arms 441 and the first end 421, and the cooperation between the second clamping arms 451 and the second end 422, can improve the stability of the multi-link structure 40, prevent loosening between the first link 41, the transmission rod 42, and the second link 43, thereby maintaining the stability of the flipping process and ensuring the stable operation of the flipping mechanism.

[0043] Please see Figure 1 and Figure 4 The drive device 30 is inclinedly mounted on the base plate 10 via a support frame 12. The support frame 12 includes a support plate 121 and a fixing plate 122. The fixing plate 122 is inclinedly mounted on the support plate 121, and the drive device 30 is fixed on the fixing plate 122, thereby achieving the inclined mounting of the drive device 30.

[0044] More specifically, the movable end 31 passes through the fixed plate 122 and is connected to the first connecting rod 41. In this embodiment, the driving device 30 is a cylinder.

[0045] Furthermore, the tilt angle of the fixed plate 122 is consistent with the tilt angle θ of the drive device 30.

[0046] Please see Figure 1 , Figure 4 , Figure 6 and Figure 7 The base plate 10 is detachably provided with a mounting seat 11 that cooperates with the flip plate 20. The mounting seat 11 and the flip plate 20 are rotatably connected via a rotating shaft 112. The mounting seat 11 can prevent the flip plate 20 from causing wear to the base plate 10 during operation, thus extending the service life of the flipping mechanism. In addition, the detachable design of the mounting seat 11 makes it convenient for workers to disassemble and assemble the mounting seat 11.

[0047] Furthermore, the mounting base 11 is recessed with a relief groove 111 to allow the rotation of the flip plate 20. The rotating shaft 112 passes through the outer wall of the mounting base 11 and the flip plate 20. The bottom wall of the relief groove 111 and the upper surface of the base plate 10 are both horizontal. In the initial state, the lower surface of the flip plate 20 is in contact with the bottom wall of the relief groove 111, and the flip angle α is 0°.

[0048] Furthermore, the flip plate 20 is provided with a chamfered structure 21 at the end that is rotatably connected to the rotating shaft 112. The chamfered structure 21 is used to prevent the flip plate 20 from interfering with the mounting base 11 when it rotates.

[0049] Furthermore, the mounting base 50 has several mounting holes 51 for mounting the detection unit or fixture.

[0050] The working process of the flipping mechanism provided by this utility model:

[0051] (1) Please refer to Figure 4 Initial state: The movable end 31 of the drive device 30 is in a naturally extended state, the flip plate 20 is in contact with the base plate 10, and the flip angle α is 0°.

[0052] (2) During operation: Start the drive device 30, the movable end 31 extends and pushes the first connecting rod 41, the first connecting rod 41 drives the transmission rod 42 to swing, and the transmission rod 42 pulls the second connecting rod 43 to drive the flip plate 20 to rotate upward around the rotating shaft 112. The fixed seat 50 follows the flip plate 20 to rotate. At this time, the included angle β gradually decreases and the flip angle α gradually increases.

[0053] (3) Please refer to Figure 6 After flipping: the flip angle α is 35°.

[0054] Additionally, please see Figure 8 The present invention also provides a gauge, including the above-mentioned flipping mechanism 1, and a plurality of detection units 100 are installed on the fixed base 50 of the flipping mechanism 1.
