[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A calibrating device for a positioner includes a support frame 1. A left reference rod, a middle reference rod, and a right reference rod are respectively installed on the top of the support frame 1. A calibrating body 2 is fixedly connected to the top of the support frame 1. An adjustment assembly 3 is provided on the top of the support frame 1. A clamping assembly 4 is provided on the top of the adjustment assembly 3. The adjustment assembly 3 includes an adjustment frame 31 fixedly connected to the top of the support frame 1. A drive motor 32 is fixedly connected to the outside of the adjustment frame 31. An adjustment screw 33 is fixedly connected to the output end of the drive motor 32. A moving block 34 is threadedly connected to the outside of the adjustment screw 33. A testing platform 35 is fixedly connected to the top of the moving block 34. Limiting sliders 36 are fixedly connected to both sides of the bottom of the testing platform 35. A limiting slide rail 37 is slidably connected to the bottom of the limiting sliders 36. The bottom of the limiting slide rail 37 is fixedly connected to the support frame 1.

[0026] In this embodiment: by activating the drive motor 32 fixed to the outside of the adjustment frame 31, the drive motor 32 outputs power to drive the adjustment screw 33 to rotate. The adjustment screw 33 and the moving block 34 are connected by a thread to convert the rotational motion into linear motion, driving the moving block 34 to move axially along the adjustment screw 33, thereby driving the adjustment platform 35 on the top of the moving block 34 to move synchronously. The limiting sliders 36 on both sides of the bottom of the adjustment platform 35 are slidably connected to the limiting slide rail 37 on the top of the support frame 1. During the movement of the adjustment platform 35, the limiting sliders 36 slide smoothly along the limiting slide rail 37, accurately limiting the movement trajectory of the adjustment platform 35, ensuring that the adjustment platform 35 always maintains linear movement and avoids deviation. Through the start, stop and forward / reverse control of the drive motor 32, the adjustment platform 35 can sequentially drive the positioner to the detection positions corresponding to the left reference rod, the middle reference rod and the right reference rod, providing stable and accurate detection conditions for the grating ruler sensor and realizing multi-point reference comparison.

[0027] Specifically, such as Figure 4 As shown, the clamping assembly 4 includes a side frame 41 fixedly connected to both sides of the adjustment table 35. An adjustment knob 42 is rotatably connected to the outer side of the side frame 41. A dual-axis screw 43 is fixedly connected to the inner side of the adjustment knob 42. The side of the dual-axis screw 43 away from the adjustment knob 42 is rotatably connected to the inner side of the side frame 41.

[0028] Specifically, such as Figure 4 As shown, both sides of the dual-axis screw 43 are threadedly connected to connecting plates 44, and the bottom of the connecting plates 44 is slidably connected to the top of the adjustment platform 35.

[0029] Specifically, such as Figure 4 As shown, several compression springs 45 are fixedly connected to the inner side of the connecting plate 44, and a clamping plate 46 is fixedly connected to the outer side of the compression springs 45. A limiting support rod 47 is provided at the connection between the clamping plate 46 and the connecting plate 44. The limiting support rod 47 passes through the interior of the connecting plate 44, and the inner side of the limiting support rod 47 is fixedly connected to the outer side of the clamping plate 46.

[0030] In this embodiment: when the positioner to be adjusted is placed at the center of the top of the adjustment platform 35, the adjustment knob 42 on the outside of the side frame 41 is then rotated. The adjustment knob 42 drives the dual-axis screw 43 on its inner side to rotate inside the side frame 41. Since the threads on both sides of the dual-axis screw 43 are opposite, its rotation will drive the connecting plates 44 connected by threads on both sides to move closer to each other along the top of the adjustment platform 35. When the connecting plates 44 move, they drive the inner compression spring 45 and the clamping plate 46 to move closer to the positioner synchronously. The protective pad on the inner side of the clamping plate 46... 11 First, it contacts both sides of the positioner. As the connecting plate 44 continues to move, the compression spring 45 is squeezed to generate elastic buffer force, which offsets the rigid impact during the clamping process. At the same time, the limiting support rod 47 between the clamping plate 46 and the connecting plate 44 passes through the connecting plate 44 to prevent the clamping plate 46 from tilting under the action of the compression spring 45, ensuring that the clamping plate 46 is always parallel and in contact with the surface of the positioner, so as to adaptively adjust the clamping distance according to the size of the positioner, realize the stable clamping of positioners of different sizes, and the clamping process is gentle and does not damage the positioner.

[0031] Specifically, such as Figure 2 As shown, the calibration body 2 is equipped with a grating ruler sensor inside, and a wire 5 is installed on the correction end of the calibration body 2. A turntable 6 is fixedly connected to the bottom of the support frame 1, and a wire fixing seat 7 is rotatably connected to the bottom of the turntable 6. The inner side of the wire fixing seat 7 is fixedly connected to the outer side of the wire 5.

[0032] Specifically, such as Figure 2 As shown, a support plate 8 is fixedly connected to the outer side of the side frame 41, and a correction socket 9 is slidably connected inside the support plate 8. The bottom of the correction socket 9 is electrically connected to the wire 5.

[0033] In this embodiment: by setting up wire 5, turntable 6, wire fixing seat 7, support plate 8 and correction socket 9, during the calibration preparation stage, the correction socket 9 is connected to the signal interface of the positioner to be calibrated, establishing a signal transmission bridge between the calibration body 2 and the positioner. The grating ruler sensor will accurately capture the actual position information of the positioner and compare it with the standard benchmark established by the reference rod to quickly identify the positioning deviation. The correction end of the calibration body 2 transmits the correction signal through wire 5, providing a signal path for parameter correction. During the process of the calibration table 35 driving the positioner to move left and right, the wire 5 will move synchronously. At this time, the turntable 6 at the bottom of the support frame 1 and the wire fixing seat 7 cooperate with each other. The wire fixing seat 7 plays a role in fixing the wire 5, and the turntable 6 rotates adaptively according to the movement direction of the wire 5, effectively limiting the range of motion of the wire 5, avoiding the wire 5 from tangling, pulling or wearing, ensuring the stability and continuity of the correction signal transmission, and ensuring that the calibration process is not interfered with by the wire 5.

[0034] Specifically, such as Figure 5As shown, a limiting slide rod 10 is fixedly connected inside the side frame 41, and the outer side of the limiting slide rod 10 is slidably connected to the side of the connecting plate 44 away from the dual-axis screw 43.

[0035] Specifically, such as Figure 5 As shown, a protective pad 11 is fixedly connected to the inner side of the clamp 46. The protective pad 11 is made of rubber.

[0036] In this embodiment: By setting a limiting slide bar 10, when the adjusting knob 42 drives the dual-axis screw 43 to rotate, the dual-axis screw 43 drives the connecting plates 44 on both sides to move relative to each other along the top of the adjustment platform 35. At this time, the limiting slide bar 10 guides and limits the movement trajectory of the connecting plates 44, preventing the connecting plates 44 from shifting, tilting, or jamming during the movement. This ensures that the connecting plates 44 on both sides always remain parallel and move smoothly, thereby ensuring that the clamping force of the clamping plate 46 on the locator is evenly distributed, and avoiding the locator being clamped crookedly due to the shift of the connecting plates 44, which would affect subsequent operations. To adjust the accuracy, a protective pad 11 is set up. When the connecting plate 44 moves the clamping plate 46 closer to the positioner and applies clamping force, the protective pad 11 first comes into contact with the surface of the positioner. Utilizing the soft and non-slip properties of the rubber material, on the one hand, rigid friction is avoided between the clamping plate 46 and the positioner, preventing scratches and damage to the positioner surface and protecting the appearance and internal structure of the positioner from damage. On the other hand, the friction between the clamping plate 46 and the positioner is enhanced, improving the stability of the clamping and preventing the positioner from sliding due to vibration or movement during the adjustment process, thus ensuring the smooth progress of the adjustment work.

[0037] Working principle: When using the calibration device for this positioner, first place the positioner to be calibrated on the top of the calibration platform 35. Then, connect the correction socket 9 on the outer support plate 8 of the side frame 41 to the positioner to establish a signal transmission channel for subsequent parameter correction. Then, rotate the adjustment knob 42. The adjustment knob 42 drives the dual-axis screw 43 inside the side frame 41 to rotate. Since the threads on both sides of the dual-axis screw 43 are opposite, its rotation will drive the connecting plates 44 connected by the threads on both sides to move relatively closer along the top of the calibration platform 35. At the same time, the side of the connecting plate 44 away from the dual-axis screw 43 slides along the limiting slide rod 10 inside the side frame 41. Under the guidance of the limiting slide rod 10, it maintains stable movement and avoids continuous movement. As the connecting plate 44 shifts, the rubber protective pad 11 on the inner side of the clamping plate 46 first contacts both sides of the locator, effectively preventing scratch damage to the locator surface during clamping. Then, the connecting plate 44 continuously applies force, generating elastic buffering through the compression spring 45 fixed inside, offsetting the rigid impact during clamping. Simultaneously, the limiting support rod 47 between the clamping plate 46 and the connecting plate 44 penetrates the connecting plate 44, effectively limiting the clamping plate 46 and preventing it from tilting during clamping. This achieves stable clamping of locators of different specifications, ensuring that the locator does not shift during adjustment. After clamping and fixing, the drive motor 32 is started. The drive motor 32 is fixed to... The output end of the adjusting frame 31 drives the adjusting screw 33 to rotate. The adjusting screw 33, through its threaded engagement with the moving block 34, drives the moving block 34 to move axially along the adjusting screw 33, thereby driving the adjustment platform 35 on top of the moving block 34 to move synchronously. The limiting sliders 36 on both sides of the bottom of the adjustment platform 35 slide along the limiting slide rail 37 on the top of the support frame 1 to ensure the straightness and stability of the adjustment platform 35 during its movement. This allows the adjustment platform 35 to sequentially move the positioner to the detection positions corresponding to the left reference rod, the middle reference rod, and the right reference rod on the top of the support frame 1. At this time, the grating ruler sensor inside the calibration body 2 fixed on the top of the support frame 1 performs positioning accuracy detection for each reference rod. By establishing a connection with the reference rod... The positioner is compared with the established standard benchmark to determine whether there is a deviation in the actual position of the positioner. When a positioning deviation is detected, the correction end of the calibration body 2 transmits the correction signal to the correction socket 9 through the wire 5, and then the correction socket 9 transmits it to the positioner to complete the accurate correction of the positioning parameters. During the process of the calibration table 35 moving the positioner, the wire 5 will move synchronously with the calibration table 35. At this time, the turntable 6 at the bottom of the support frame 1 and the wire fixing seat 7 cooperate with each other. The wire fixing seat 7 fixes the wire 5, and the turntable 6 rotates adaptively with the movement of the wire 5, which plays a role in limiting and organizing the wire 5, effectively preventing the wire 5 from getting tangled, pulled or worn, ensuring the stability of signal transmission, and ensuring that the entire calibration process is carried out smoothly.
