Abstract
Description
Technical Field
[0001] This invention relates to the field of tooling and fixture technology, and in particular to a calibration tooling for batch intelligent testing based on digital sensors. Background Technology

[0047] Beneficial effects
[0048] Compared with traditional calibration fixtures, the digital sensor calibration fixtures according to various embodiments of the present invention make it easier for staff to collect the calibrated digital sensors. Furthermore, the present invention can slightly change the angle during calibration testing, which improves the calibration testing accuracy. It also allows staff to adjust the spacing between digital sensors appropriately according to calibration testing requirements. Moreover, the digital sensors can be automatically limited when clamped, avoiding shaking during digital sensor calibration testing.
[0049] Furthermore, because the two connectors are rotatably installed inside the two support frames, when the digital sensor calibration test is completed, the operator rotates the mounting frame 180 degrees clockwise. At this point, the calibrated digital sensor is located at the top of the collection box, facilitating the collection of the calibrated digital sensor and improving the calibration test efficiency. Since the four fixed posts are slidably installed on the outside of the four fixed seats, and springs are installed on the inside of the four fixed posts, and the outer ends of the four fixed posts are hemispherical structures inserted into the four fixed slots, the digital sensor is more stable during calibration and removal. Also, because bevel gear B meshes with bevel gear A, and gear A meshes with the gear sleeve, when the operator removes the digital sensor and continues to rotate the mounting frame 180 degrees clockwise, the support seat undergoes a slight angle change. This allows the invention to undergo slight angle changes during use, improving calibration test accuracy and increasing the batch calibration test efficiency of the digital sensor.
[0050] Furthermore, because the fixing pins are inserted into the through holes and the base plate, it is convenient for the staff to adjust the spacing between the digital sensors appropriately according to the calibration test requirements, thereby meeting different calibration test requirements and improving the versatility of the invention. When the digital sensor is located between the two clamping plates, when the staff rotates the screw clockwise, the rear fixing plate moves inward. Since the two racks are fixedly connected to the two clamping plates, and gear C is meshed with the two racks, the two fixing plates move simultaneously. This improves the clamping efficiency of the digital sensor and ensures that the digital sensors to be calibrated are all located on the same central plane, thus improving the consistency of the calibration test. In addition, since the four limiting plates are fixedly installed at the inner ends of the eight guide pillars, and the four drive pillars penetrate the four mounting plates and are fixedly installed on the outer side of the four limiting plates, and the two pushers are fixedly installed on the top of the base plate, when the two clamping plates move inward simultaneously, causing the four drive pillars to contact the two pushers, the four limiting plates move inward simultaneously, which facilitates the limiting of the digital sensor, avoids shaking during the digital sensor calibration test, and improves the calibration test accuracy of the digital sensor.

Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.
[0071] Example: Please refer to Figures 1 to 14 :
[0072] This invention proposes a calibration fixture for batch intelligent testing of digital sensors, comprising an installation component 1; a support device 2 is mounted on the top of the installation component 1, and a rotating mechanism 3 is mounted on the support device 2, and a driving mechanism 4 is mounted on the right side of the support device 2, and a collecting device 5 is mounted on the top of the support device 2; a fixing device 6, of which four sets are provided, and the four sets of fixing devices 6 are installed on the left and right sides of the support device 2; three sets of clamping mechanisms 7 are installed inside the rotating mechanism 3, and connecting devices 8 are installed on the left and right sides of the three sets of clamping mechanisms 7, and limit components 9 are installed on the three sets of clamping mechanisms 7.
[0073] Furthermore, according to embodiments of the present invention, such as Figures 3 to 10As shown, the mounting assembly 1 includes: a base 101, with a mounting block 1011 fixedly mounted at the top center of the base 101, and two mounting holes 1012 penetrating through the base 101; a gear sleeve 102, which is fixedly mounted on the outer wall of the base 101; the support device 2 includes: a support base 201, which is rotatably connected to the mounting block 1011 via a bearing; two support frames 202, which are fixedly mounted on the top of the support base 201, and have two fixing grooves 2021 on their inner sides; and the rotating mechanism 3 includes: two connectors 301, which are rotatably mounted inside the two support frames 202; and a mounting frame 302, which is fixedly mounted between the two connectors 301, with a through hole 3021 penetrating through the mounting frame 302, and a mounting groove 3021 on its rear side. The drive mechanism 4 includes a sliding groove 3022 and includes: a connecting shaft 401, which is fixedly connected to the right connecting piece 301, and a bevel gear A4011 is fixedly installed on the right side of the connecting shaft 401; a connecting plate 402, which is fixedly connected to the right support frame 202; a drive shaft 403, which is rotatably installed inside the connecting plate 402, and a bevel gear B4031 is fixedly installed on the top of the drive shaft 403, and the bevel gear B4031 meshes with the bevel gear A4011; and a gear A404, which is fixedly installed at the bottom of the drive shaft 403, and the gear A404 meshes with the gear sleeve 102. The collection device 5 includes: a collection frame 501, which is fixedly connected to the support base 201; and a collection box 502, which is slidably installed inside the collection frame 501. The fixing device 6 includes: a fixing seat 601, which is fixedly connected to the connecting piece 301.The fixing post 602 is slidably installed on the outside of the fixing base 601, and a spring is installed on the inside of the fixing post 602. The outer end of the fixing post 602 is a hemispherical structure and is inserted into the fixing groove 2021. Its specific function is as follows: Since the two connecting pieces 301 are rotatably installed inside the two support frames 202, when the digital sensor calibration test is completed, the operator rotates the mounting frame 302 180 degrees clockwise. At this time, the digital sensor after calibration test is located on the top of the collection box 502, which facilitates the operator to collect the digital sensor after calibration test and improves the calibration test efficiency of the digital sensor. Since the four fixing posts 602 are slidably installed on the four fixing bases 601, the fixing post 602 is slidably installed on the four fixing bases 601. On the outside of 01, and on the inside of the four fixing posts 602, springs are installed, and the outer ends of the four fixing posts 602 are hemispherical structures. The outer ends of the four fixing posts 602 are inserted into the four fixing slots 2021, thus making the digital sensor more stable during calibration testing and removal. Furthermore, because bevel gear B4031 meshes with bevel gear A4011, and gear A404 meshes with gear sleeve 102, when the digital sensor is removed and the mounting frame 302 is rotated 180 degrees clockwise, the support base 201 undergoes a slight angle change. This allows the invention to undergo slight angle changes during use, improving calibration testing accuracy and increasing the efficiency of batch calibration testing of digital sensors.
[0074] Furthermore, according to embodiments of the present invention, such as Figures 11 to 14As shown, the clamping mechanism 7 includes: a base plate 701, which is slidably connected to the mounting frame 302; a fixing pin 702, which is inserted into the through hole 3021 and the base plate 701; two fixing plates 703, which are fixedly installed on the top of the base plate 701; four guide rods 704, which are slidably installed on the two fixing plates 703; and a clamping plate 70. 5. Two clamping plates 705 are provided, and the two clamping plates 705 are fixedly installed on the inner ends of the four guide rods 704; a lead screw 706 is rotatably connected to the rear clamping plate 705, and the lead screw 706 is threadedly connected to the rear fixing plate 703, and the lead screw 706 is slidably connected to the slide groove 3022. The connecting device 8 includes: two racks 801, and the two racks 801 are fixedly connected to the two clamping plates 705; a fixing block 802, which fixes... Block 802 is fixedly installed on the top of base plate 701; gear C803 is rotatably installed on fixed block 802 via a rotating shaft, and gear C803 meshes with two racks 801. The limiting assembly 9 includes: mounting plates 901, four mounting plates 901 are provided, and the four mounting plates 901 are fixedly installed on the inner side of two clamping plates 705; guide posts 902, eight guide posts 902 are provided, and the eight guide posts 902 are slidably installed on the four mounting plates 901, and springs are installed on the outside of the eight guide posts 902; limiting plates 903, four limiting plates 903 are provided, and the four limiting plates 903 are fixedly installed on the inner end of the eight guide posts 902; drive posts 904, four drive posts 904 are provided, and the four drive posts 904 penetrate the four mounting plates 901, and the four drive posts 904 are fixedly installed on the outer side of the four limiting plates 903, and the outer end of the four drive posts 904 is a hemispherical structure.Two pushers 905 are provided and fixedly installed on the top of the base plate 701. Their specific function is as follows: Because the fixing pin 702 is inserted and connected to the through hole 3021 and the base plate 701, it is convenient for the operator to adjust the spacing between the digital sensors appropriately according to calibration and testing requirements, thus meeting different calibration and testing requirements and improving the versatility of the invention. When the digital sensor is located between the two clamping plates 705, when the operator rotates the lead screw 706 clockwise, the rear fixing plate 703 moves inward. Because the two racks 801 are fixedly connected to the two clamping plates 705, and the gear C803 meshes with the two racks 801, the two fixing plates 703 move simultaneously, thereby improving the stability of the digital sensor. This design improves clamping efficiency and ensures that all digital sensors to be calibrated are located on the same central plane, enhancing the consistency of calibration tests. Furthermore, because four limiting plates 903 are fixedly installed at the inner ends of eight guide pillars 902, and four drive pillars 904 penetrate four mounting plates 901 and are fixedly installed on the outer sides of the four limiting plates 903, and two pushers 905 are fixedly installed on the top of the base plate 701, when the two clamping plates 705 move inward simultaneously, causing the four drive pillars 904 to contact the two pushers 905, the four limiting plates 903 move inward simultaneously, facilitating the limiting of the digital sensors and preventing shaking during calibration tests, thus improving the calibration accuracy of the digital sensors.
[0075] The specific usage and function of this embodiment: In this invention, the operator first installs the invention in a suitable position through the two mounting holes 1012. Then, according to the calibration test requirements, the operator appropriately adjusts the spacing between the digital sensors to meet different calibration test requirements, thus improving the versatility of the invention. Next, the digital sensor to be calibrated is placed between the two clamping plates 705 in the three sets of clamping mechanisms 7. When the operator rotates the lead screw 706 clockwise, the rear fixing plate 703 moves inward. Because the two racks 801 are fixedly connected to the two clamping plates 705, and the gear C803 is meshed with the two racks 801, from... The simultaneous movement of the two fixing plates 703 improves the clamping efficiency of the digital sensors and ensures that all digital sensors to be calibrated are located on the same central plane, thus improving the consistency of the calibration test. Furthermore, since the four limiting plates 903 are fixedly installed on the inner ends of the eight guide pillars 902, and the four drive pillars 904 penetrate the four mounting plates 901 and are fixedly installed on the outer sides of the four limiting plates 903, and the two pushing members 905 are fixedly installed on the top of the base plate 701, when the two clamping plates 705 move inward simultaneously, causing the four drive pillars 904 to contact the two pushing members 905... At this time, the four limiting plates 903 move inward simultaneously to limit the digital sensor, preventing shaking during calibration testing and improving the calibration accuracy. Then, when the operator rotates the mounting frame 302 180 degrees clockwise, the calibrated digital sensor is located on top of the collection box 502, facilitating collection and improving calibration efficiency. This is because the four fixing posts 602 are slidably mounted on the outside of the four fixing seats 601, and springs are installed on the inside of the four fixing posts 602. The end is a hemispherical structure, and the outer ends of the four fixed posts 602 are inserted into the four fixed slots 2021, which makes the digital sensor more stable during calibration and removal. Since the bevel gear B4031 is meshed with the bevel gear A4011, and the gear A404 is meshed with the gear sleeve 102, when the operator removes the digital sensor and then rotates the mounting frame 302 180 degrees clockwise, the support base 201 undergoes a slight angle change. This allows the invention to undergo slight angle changes during use, improving calibration accuracy and batch calibration efficiency of the digital sensor.
[0076] Finally, it should be noted that when describing the position of each component and the mating relationship between them, the present invention usually uses one or a pair of components as examples. However, those skilled in the art should understand that such positions, mating relationships, etc., are also applicable to other components or other pairs of components.
