Moreover, the accuracy of manually detecting chain plate data is low, leading to large errors in chain plate detection and poor stability of chain plate data. Summary of the Invention

[0006] (2) Technical Solutions

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: An improved bending chain plate pitch, aperture, and bending distance detector, comprising a fixed base, a grating ruler, a positioning probe, a movable probe, and a height gauge probe. Two support frames are fixedly connected to the top of the fixed base. The height gauge probe is fixedly connected to the top of the fixed base and is located between the two support frames. A fixed plate is fixedly connected to the side wall of one of the support frames close to the height gauge probe. The grating ruler is fixedly connected to the side wall of the fixed plate close to the other support frame, and the end of the grating ruler away from the fixed plate is fixedly connected to the other support frame. A first telescopic rod is fixedly connected to the bottom of the fixed plate, and the positioning probe is fixedly connected to the movable bottom end of the first telescopic rod. A fixed block is fixedly connected to the front surface of the moving mechanism of the grating ruler, and a second telescopic rod is fixedly connected to the bottom of the fixed block. The movable probe is fixedly connected to the movable bottom end of the second telescopic rod. Both the positioning probe and the movable probe are trapezoidal cone probes. Two threaded rods are rotatably connected to the top of the fixed base, and rotating handles are fixedly connected to the tops of both threaded rods. The outer surfaces of both threaded rods are threadedly connected with movable plates. One of the movable plates is located below the positioning probe. A first slot is opened on the top of one of the movable plates, and a first radius gauge is movably clamped inside the first slot. A second slot is opened on the bottom of the other movable plate, and a second radius gauge is movably clamped inside the second slot. The arc end faces of the first radius gauge and the second radius gauge face each other. A digital display is fixedly connected to the front surface of one of the support frames.

[0008] Preferably, the height gauge probe is located between the positioning probe and one of the support frames.

[0009] Preferably, two limit rods are fixedly connected to the top of the fixed base. Both limit rods are located between the two support frames. The two limit rods respectively penetrate through the two movable plates, and both threaded rods are located between the two limit rods.

[0010] Preferably, the lengths of the first slot and the second slot are the same as the length of the movable plate.

[0011] Preferably, limit blocks are fixedly connected to the front and rear surfaces of the second radius gauge, and limit grooves are opened on the front and rear walls inside the second slot. The limit blocks are movably clamped inside the limit grooves.

[0012] Working principle: When in use, place the bending link plate to be detected on the fixed base so that one of the pin holes on the bending link plate is directly below the positioning probe. By rotating the turning handle, the threaded rod can be driven to rotate, and the limiting rod can limit the movement of the movable plate, enabling the threaded rod to drive the movable plate to move linearly up and down. As a result, the heights of the first radius gauge and the second radius gauge on the two movable plates can be changed respectively, facilitating the first radius gauge to fit with the bottom end face and the second radius gauge to fit with the top end face. Since the first radius gauge can move linearly along the first slot on one of the movable plates and the second radius gauge can move linearly along the second slot on the other movable plate, the positions of the first radius gauge and the second radius gauge can be changed, so that the first radius gauge and the second radius gauge fit with the bending part of the bending link plate, facilitating the first radius gauge to detect the bending part of the bottom end face of the bending link plate and the second radius gauge to detect the bending part of the top end face of the bending link plate. The distance between the two bends can be calculated by centering on the bending arcs of the first radius gauge and the second radius gauge. Moreover, since rotating the turning handle can drive the threaded rod to drive the movable plate to rotate, the first radius gauge and the second radius gauge on the two movable plates can respectively fix the upper and lower end faces of the bending link plate, facilitating the improvement of the detection accuracy of the bending link plate. When the bending link plate is clamped and fixed by the first radius gauge and the second radius gauge, move the fixed block on the grating ruler to drive the movable probe on the second telescopic rod to move linearly, so that the movable probe moves to directly above another pin hole on the bending link plate. Stretch the first telescopic rod and the second telescopic rod so that the positioning probe on the first telescopic rod and the movable probe on the second telescopic rod respectively enter the two pin holes on the bending link plate. The positioning probe on the first telescopic rod can detect the aperture of one of the pin holes on the bending link plate, and the movable probe on the second telescopic rod can detect the aperture of the other pin hole on the bending link plate. The grating ruler can measure the moving stroke of the movable probe, so that the center distance between the two holes can be calculated by centering on the apertures of the two holes. Through the set height gauge probe, since the height gauge probe can detect the height of the bottom end face of the bending part of the bending link plate, the bending height of the bending link plate can be detected. Therefore, this device can realize the detection of the pitch, aperture, and bending distance of the bending link plate, improve the detection efficiency, reduce the measurement error of people and the data stability, and facilitate the release of the detection and recording time of the detection personnel.

[0013] (III) Beneficial effects

[0014] The present invention provides an improved pitch, aperture, and bending distance detector for bending link plates. It has the following beneficial effects:

[0015] 1. The improved pitch, hole diameter, and bending distance detector for the bending chain plate, through the set grating ruler, first telescopic rod, positioning probe, fixed block, second telescopic rod, and movable probe. Since the positioning probe on the first telescopic rod can detect the hole diameter of one of the pin holes on the bending chain plate, and the fixed block can drive the movable probe on the second telescopic rod to move linearly, enabling the movable probe on the second telescopic rod to detect the hole diameter of another pin hole on the bending chain plate. The grating ruler can measure the moving stroke of the movable probe, so that the center distance between the two holes can be calculated with the center of the two hole diameters, which can improve the detection efficiency, reduce the measurement error of people and the stability of data, and facilitate the release of the detection and recording time of the detection personnel.

[0016] 2. The improved pitch, hole diameter, and bending distance detector for the bending chain plate, through the set threaded rod, movable plate, turning handle, first radius gauge, second radius gauge, first slot, second slot, limiting block, and limiting groove. Since the first radius gauge can move linearly along the first slot on one of the movable plates, and the second radius gauge can move linearly along the second slot on the other movable plate, the positions of the first radius gauge and the second radius gauge can be changed. By turning the turning handle, the position of the movable plate can be changed, so that the positions of the first radius gauge and the second radius gauge on the two movable plates can be changed respectively, thus enabling the first radius gauge and the second radius gauge to fit with the bending part of the bending chain plate, facilitating the first radius gauge to detect the bending part at the bottom end face of the bending chain plate, and the second radius gauge to detect the bending part at the top end face of the bending chain plate. The distance dimension between the two bends can be calculated with the center of the bending arcs of the first radius gauge and the second radius gauge.

[0017] 3. The improved pitch, hole diameter, and bending distance detector for the bending chain plate, through the set height gauge probe. Since the height gauge probe can detect the height of the bottom end face of the bending part of the bending chain plate, the bending height of the bending chain plate can be detected. And because turning the rotation can drive the threaded rod to drive the movable plate to rotate, the first radius gauge and the second radius gauge on the two movable plates can respectively fix the upper and lower end faces of the bending chain plate, facilitating the improvement of the detection accuracy of the bending chain plate.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Embodiment:

[0024] As Figures 1-3 shown, the embodiment of the present invention provides an improved bending chain plate pitch, hole diameter, and bending distance detector, including a fixed base 1, a grating ruler 4, a positioning probe 6, a movable probe 9, and a height gauge probe 10. Two support frames 2 are fixedly connected to the top of the fixed base 1. The height gauge probe 10 is fixedly connected to the top of the fixed base 1. The height gauge probe 10 is located between the two support frames 2. A fixed plate 3 is fixedly connected to the side wall of one of the support frames 2 close to the height gauge probe 10. The grating ruler 4 is fixedly connected to the side wall of the fixed plate 3 close to the other support frame 2. One end of the grating ruler 4 away from the fixed plate 3 is fixedly connected to the other support frame 2. A first telescopic rod 5 is fixedly connected to the bottom of the fixed plate 3. The positioning probe 6 is fixedly connected to the movable bottom end of the first telescopic rod 5. A fixed block 7 is fixedly connected to the front surface of the moving mechanism of the grating ruler 4. A second telescopic rod 8 is fixedly connected to the bottom of the fixed block 7. The movable probe 9 is fixedly connected to the movable bottom end of the second telescopic rod 8. Both the positioning probe 6 and the movable probe 9 are trapezoidal cone probes. Two threaded rods 11 are rotatably connected to the top of the fixed base 1. Rotating handles 14 are fixedly connected to the tops of the two threaded rods 11. Movable plates 15 are threadedly connected to the outer surfaces of the two threaded rods 11. One of the movable plates 15 is located below the positioning probe 6. A first slot 18 is opened on the top of one of the movable plates 15. A first radius gauge 16 is movably clamped inside the first slot 18. A second slot 20 is opened on the bottom of the other movable plate 15. A second radius gauge 17 is movably clamped inside the second slot 20. The arc end faces of the first radius gauge 16 and the second radius gauge 17 face each other. A digital display 12 is fixedly connected to the front surface of one of the support frames 2.

[0025] The height gauge probe 10 is located between the positioning probe 6 and one of the support frames 2. Through the height gauge probe 10, the height of the bottom end surface of the bent part of the bent link plate can be detected, so that the bending height of the bent link plate can be detected. Two limiting rods 13 are fixedly connected to the top of the fixed base 1. Both of the two limiting rods 13 are located between the two support frames 2. The two limiting rods 13 respectively penetrate through the two movable plates 15. Both of the two threaded rods 11 are located between the two limiting rods 13. The limiting rods 13 can limit the movable plates 15, so that the threaded rods 11 can drive the movable plates 15 to move linearly up and down, facilitating the separate adjustment of the heights of the first radius gauge 16 and the second radius gauge 17 on the two movable plates 15. The lengths of the first slot 18 and the second slot 20 are the same as the length of the movable plate 15, so that the first radius gauge 16 in the first slot 18 and the second radius gauge 17 in the second slot 20 can both be removed and replaced, facilitating the use of bent link plates of different specifications. Limiting blocks 19 are fixedly connected to the front and rear surfaces of the second radius gauge 17. Limiting grooves 21 are respectively formed in the front and rear walls inside the second slot 20. The limiting blocks 19 are movably clamped inside the limiting grooves 21. Since the limiting blocks 19 on the second radius gauge 17 are clamped in the limiting grooves 21, the position of the second radius gauge 17 is limited, so that the second radius gauge 17 will not fall out of the second slot 20.
