Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, in particular to a calibration auxiliary device for measuring instruments. Background Technique

[0002] A measuring instrument is a third-party standard required for measuring certain attribute values of an object. Measuring instruments generally have scales, volumes and other units. The basic content of the concept of measuring instruments includes: accuracy, error, measuring standard equipment, length measurement, angle measurement, shape measurement, traditional optical instruments. Applications in precision measurement, etc.

[0003] In most existing calibration auxiliary devices, when measuring standard equipment, for example, data such as length, angle, and shape need to be measured one by one and the corresponding data needs to be recorded. However, most devices lack a device that can flexibly adjust the angle and position for calibration, resulting in great trouble during measurement and relatively affecting the detection efficiency. Therefore, we urgently need a calibration auxiliary device for measuring instruments to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a calibration auxiliary device for measuring instruments, which solves the problems raised in the background technique.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: A calibration auxiliary device for measuring instruments includes a clamping seat. On the upper surface of the clamping seat, placing grooves are opened on both the left and right sides. A hydraulic cylinder I is fixedly installed in the placing groove. The output end of the hydraulic cylinder I is fixedly installed with a moving plate. On both the left and right sides of the upper surface of the clamping seat, clamping plates I are arranged, and the lower surface of the clamping plate I is fixedly connected with the corresponding moving plate. On the lower surface of the clamping seat, a rotating disk is arranged, and a placing hole is opened at the central position of the rotating disk. A driving motor I is fixedly installed in the placing hole. One end of a transmission rod I is fixedly connected to the output end of the driving motor I, and the other end is fixedly connected with the clamping seat. The lower surface of the clamping seat is in contact with the upper surface of the rotating disk. A calibration component is arranged on the clamping seat;

[0006] The calibration component includes a base. On the upper surface of the base, a bracket is fixedly installed. The bracket is fixedly connected with a mounting frame I. A driving motor II is fixedly installed in the mounting frame I. One end of a transmission rod II is fixedly connected to the output end of the driving motor II, and the other end of the transmission rod II is fixedly connected with a rotating plate.

[0007] Through the above technical solutions, the setting of the driving motor I is used for the small-angle movement of the instrument clamped on the clamping seat.

[0008] Preferably, an annular track is fixedly installed on the rotating plate, and a first driving block is slidably connected to the annular track. A scale dial is fixedly installed on the upper surface of the rotating plate and outside the annular track. A pointer is fixedly installed on the first driving block, and the pointer contacts the scale dial.

[0009] Through the above technical solution, the scale dial of the present application is used to more intuitively observe the moving angle of the instrument after the instrument moves, ensuring that the moving position is more accurate.

[0010] Preferably, a bearing hole is opened at the central position of the rotating plate. A rotating rod is rotatably connected to the bearing hole through a bearing. Hydraulic cylinders II are fixedly installed on the left and right sides of the rotating plate outside the rotating rod. The output ends of the two hydraulic cylinders II are fixedly connected to a second clamping plate, and the second clamping plate contacts the rotating rod.

[0011] Through the above technical solution, the hydraulic cylinder II of the present application is in an unstarted state when the rotating rod moves. When the rotating rod stops rotating, the hydraulic cylinder II will drive the second clamping plate to clamp and limit the rotating rod.

One end of a robotic arm is fixedly connected to the output end of the third driving motor, and the other end of the robotic arm is connected to a robotic hand.

[0013] Through the above technical solution, the robotic arm of the present application can move at multiple angles. The joints are driven by joint motors. The robotic hand has a clamping function for clamping the placement base. When the robotic arm moves the first driving block on the annular track, the robotic arm is in a straight state for supporting the placement base.

[0014] Preferably, a magnetic attraction slider is fixedly installed on the upper surface of the first driving block. A placement base is arranged on the first driving block. The placement base is slidably connected to the magnetic attraction slider through a magnetic attraction sliding groove opened thereon. A first magnet is fixedly installed on the lower surface of the rotating disk, and a second magnet is fixedly installed on the upper surface of the placement base, and the first magnet and the second magnet are magnetically attracted to each other.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figures 1-4, the present utility model provides a technical solution: a calibration auxiliary device for a measuring instrument, including a clamping seat 1. On the left and right sides of the upper surface of the clamping seat 1, placing grooves 2 are respectively opened. Inside the placing grooves 2, a first hydraulic cylinder 3 is fixedly installed. The output end of the first hydraulic cylinder 3 is fixedly installed with a moving plate 4. On the left and right sides of the upper surface of the clamping seat 1, first clamping plates 5 are respectively arranged, and the lower surface of the first clamping plate 5 is fixedly connected to the corresponding moving plate 4. On the lower surface of the clamping seat 1, a rotating disk 6 is arranged, and a placing hole 7 is opened at the central position of the rotating disk 6. Inside the placing hole 7, a first driving motor 8 is fixedly installed. One end of a first transmission rod 10 is fixedly connected to the output end of the first driving motor 8, and the other end is fixedly connected to the clamping seat 1. The lower surface of the clamping seat 1 is in contact with the upper surface of the rotating disk 6. A calibration assembly 9 is arranged on the clamping seat 1;

[0028] The calibration assembly 9 includes a base 91. On the upper surface of the base 91, a support 92 is fixedly installed. The support 92 is fixedly connected to a first mounting frame 93. Inside the first mounting frame 93, a second driving motor 94 is fixedly installed. One end of a second transmission rod 95 is fixedly connected to the output end of the second driving motor 94, and the other end of the second transmission rod 95 is fixedly connected to a rotating plate 96. The setting of the first driving motor 8 is used for the small-angle movement of the instrument clamped on the clamping seat 1.

[0029] On the rotating plate 96, an annular track 97 is fixedly installed, and a first driving block 98 is slidably connected to the annular track 97. On the upper surface of the rotating plate 96 and outside the annular track 97, a scale disk 99 is fixedly installed. A pointer 910 is fixedly installed on the first driving block 98, and the pointer 910 is in contact with the scale disk 99. The scale disk 99 in this application is used to more intuitively observe the moving angle of the instrument after the instrument moves, ensuring that the moving position is more accurate.

[0030] At the central position of the rotating plate 96, a bearing hole 911 is opened. Inside the bearing hole 911, a rotating rod 912 is rotatably connected through a bearing. On the left and right sides of the rotating plate 96 and outside the rotating rod 912, second hydraulic cylinders 913 are fixedly installed. The output ends of the two second hydraulic cylinders 913 are fixedly connected to a second clamping plate 914. The second clamping plate 914 is in contact with the rotating rod 912. In this application, the second hydraulic cylinders 913 are in an unactivated state when the rotating rod 912 moves. When the rotating rod 912 stops rotating, the second hydraulic cylinders 913 will drive the second clamping plate 914 to clamp and limit the rotating rod 912.

[0031] One end of the rotating rod 912 away from the rotating plate 96 is fixedly connected with a second mounting bracket 915, and a third driving motor 916 is fixedly connected inside the second mounting bracket 915. One end of a robotic arm 917 is fixedly connected to the output end of the third driving motor 916, and the other end of the robotic arm 917 is connected with a mechanical hand 918. The robotic arm 917 of the present application can move at multiple angles, and the joints are driven by joint motors. The mechanical hand 918 has a clamping function and is used to clamp the placement base 920. When the robotic arm 917 drives the first driving block 98 to move on the circular track 97, the robotic arm 917 is in a straight state and is used to support the placement base 920.

[0032] A magnetic attraction slider 919 is fixedly installed on the upper surface of the first driving block 98. A placement base 920 is arranged on the first driving block 98. The placement base 920 is slidably connected with the magnetic attraction slider 919 through a magnetically attracted sliding groove 921 opened thereon. A first magnet 922 is fixedly installed on the lower surface of the rotating disk 6, and a second magnet 923 is fixedly installed on the upper surface of the placement base 920, and the first magnet 922 and the second magnet 923 are magnetically attracted to each other. In the present application, after the driving track 97 drives the first driving block 98 to move to the corresponding position, the robotic arm 917 pulls the placement base 920 outwards from the first driving block 98 through the drive of the joint motor, and moves through the third driving motor 916 and the joint arm 917, so as to complete a more accurate calibration work and record the data.

[0033] The mechanical hand 918 contacts and clamps the placement base 920.

[0034] When the calibration auxiliary device of the measuring instrument is working, the instrument is placed horizontally on the clamping seat 1. Driven by the hydraulic cylinders 1-3 on both sides, the clamping plate 1-5 on the moving plate 4 drives to clamp the instrument. The magnet 1-922 under the rotating disk 6 is adsorbed to the magnet 2-923 on the placing base 920. The magnetic sliding groove 921 on the installed placing base 920 is slidably inserted into the magnetic sliding block 919 on the driving block 1-98 and fixed by magnetic adsorption. After the robotic arm 917 is moved to a straight state, the manipulator 918 is used to clamp the placing base 920. When a calibration test is performed, first, the driving motor 2-94 drives the rotating plate 96 to move at a large angle. When it moves to the corresponding position, the annular track 97 drives the driving block 1-98 to move, positioning to the precise angle, and the pointer 910 on the driving block 1-98 points to the scale disk 99 to read the current moving angle. When the driving block 1-98 rotates on the annular track 97, the robotic arm 917 rotates through the rotating rod 912 in the bearing hole 911. When the driving block 1-98 stops moving on the annular track 97, the hydraulic cylinder 2-913 drives the clamping plate 2-914 to clamp and limit the rotating rod 912. The driving motor 3-916 starts and drives the robotic arm 917 to move. After the robotic arm 917 pulls the placing base 920 out of the magnetic sliding block 919 on the driving block 1-98, the robotic arm 917 cooperates with the manipulator 918 to move the placing base 920 to the measuring position, and the stability provided by the robotic arm 917 is used to calibrate and measure the item. By adjusting the driving motor 1-8 to drive the clamping seat 1 to move, a small-angle offset can also be achieved, which is used to increase the measurement range. When the detection of one position is completed, the robotic arm 917 drives the placing base 920 to move to the driving block 1-98 again, and the driving block 1-98 is driven by the annular track 97 to move the instrument to the next measuring position.
