[0020] 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.

[0021] like Figures 1 to 4 As shown, this utility model provides an automatic zeroing and positioning mechanism for a high-precision caliper, including a worktable 1. Multiple placement plates 2 are arranged above the worktable 1. The bottom of each placement plate 2 is connected to the top of the worktable 1 via a support rod 9. The top of the worktable 1 is vertically connected to the bottom of a first baffle 10. The side of the first baffle 10 abuts against the side of the outermost placement plate 2. The top of each placement plate 2 is provided with a fixing mechanism for limiting the caliper's position. A movable plate 15 is arranged above the placement plate 2, and a slide rail is provided at the bottom of the movable plate 15. The slide rail groove 3 is equipped with a first electric slide rail 4 and a second electric slide rail 7 arranged opposite to each other. The first electric slide rail 4 and the second electric slide rail 7 are respectively connected to the first clamping plate 5 and the second clamping plate 8 through sliders. The top of the moving plate 15 is connected to the transverse electric slide rail 13 through sliders. The side of the transverse electric slide rail 13 is connected to the top of the workbench 1 through the bracket 14. An image recognition device 23 and a lifting cylinder 25 are installed on the moving plate 15 on one side of the slide rail groove 3. The extension end of the lifting cylinder 25 is connected to the top of the pressing shaft 26.

[0022] The image recognition device 23 can be an image recognition device in the prior art, which can automatically recognize the numbers on the electronic display screen of the caliper and the position of the measuring jaws of the caliper;

[0023] By setting up the placement plate 2, the calipers to be calibrated can be placed on the placement plate 2 during calibration, and fixed by the fixing mechanism to prevent the calipers from shaking during the calibration process. Then, driven by the horizontal electric slide rail 13, the first clamping plate 5 and the second clamping plate 8 are moved to both sides of the electronic display screen. Then, under the action of the first electric slide rail 4 and the second electric slide rail 7, the first clamping plate 5 and the second clamping plate 8 are controlled to move to both sides of the electronic display screen, contacting the two sides of the electronic display screen, thereby completing the calibration of the electronic display screen. Clamping is then performed, and the electric display screen can be moved back and forth under the drive of the horizontal electric slide rail 13, thereby driving the measuring jaw connected to the electronic display screen to move synchronously. When zeroing is required, the movable measuring jaw and the fixed measuring jaw are brought into contact by the drive of the horizontal electric slide rail 13. The image recognition device 23 identifies whether the movable measuring jaw and the fixed measuring jaw are in contact. After contact is completed, the lifting cylinder 25 is extended and retracted by controlling it, which drives the pressing shaft 26 to move downward and press the zeroing button on the electronic display screen to complete the zeroing operation of the caliper.

[0024] The above structure enables automatic calibration of calipers without manual operation, preventing changes in personnel from affecting calibration accuracy and effectively improving the calibration quality of the product.

[0025] The fixing mechanism includes a fixing groove 17, and a left electric slide rail 21 and a right electric slide rail 18 are installed at both ends inside the fixing groove 17. The left electric slide rail 21 and the right electric slide rail 18 are respectively connected to the left fixing plate 22 and the right fixing plate 19 through sliders.

[0026] By setting up the left electric slide rail 21 and the right electric slide rail 18, the left fixed plate 22 and the right fixed plate 19 can be driven to move in opposite directions or in opposite directions, thereby realizing the automatic clamping operation of the electronic display screen.

[0027] The left and right fixed plates 22 and 19 are respectively bonded with a left buffer pad 27 and a right buffer pad 20 on their opposite sides, and the left buffer pad 27 and the right buffer pad 20 are made of rubber.

[0028] By setting up left and right buffer pads 27 and 20 made of rubber, the elasticity of the left and right buffer pads 27 and 20 can be used to reduce the pressure at the clamping point of the electronic display screen, preventing the electronic display screen from being damaged due to excessive force, which would affect its subsequent use.

[0029] The first clamping plate 5 and the second clamping plate 8 are respectively bonded with a first clamping pad 6 and a second clamping pad 16 on their opposite sides, and the first clamping pad 6 and the second clamping pad 16 are made of rubber.

[0030] By setting the first clamping pad 6 and the second clamping pad 16 made of rubber, the elasticity of the first clamping pad 6 and the second clamping pad 16 can be used to reduce the pressure at the clamping point of the caliper, prevent the caliper from being damaged due to excessive force, and affect subsequent use.

[0031] The first baffle 10 has a second baffle 11 on one side. The second baffle 11 is connected to the lower electric slide rail 12 via a slider. The lower electric slide rail 12 is installed on the top of the workbench 1.

[0032] By setting a second baffle 11 and driving it through the lower electric slide rail 12, the second baffle 11 can move automatically, thereby abutting one end of the caliper and cooperating with the first baffle 10 to improve the stability of the baffle when it is placed.

[0033] A rectangular protective frame 24 is installed at the bottom of the movable plate 15 on the outside of the image recognizer 23.

[0034] By setting the protective frame 24, the image recognizer 23 can be shielded from light, reducing the influence of external light on the image recognizer 23 and improving the recognition accuracy of the image recognizer 23.

[0035] Working principle and usage process of this utility model:

[0036] By setting up the placement plate 2, the calipers to be calibrated can be placed on the placement plate 2 during calibration, and fixed by the fixing mechanism to prevent the calipers from shaking during the calibration process. Then, driven by the horizontal electric slide rail 13, the first clamping plate 5 and the second clamping plate 8 are moved to both sides of the electronic display screen. Then, under the action of the first electric slide rail 4 and the second electric slide rail 7, the first clamping plate 5 and the second clamping plate 8 are controlled to move to both sides of the electronic display screen, contacting the two sides of the electronic display screen, thereby completing the calibration of the electronic display screen. Clamping is then performed, and the electric display screen can be moved back and forth under the drive of the horizontal electric slide rail 13, thereby driving the measuring jaw connected to the electronic display screen to move synchronously. When zeroing is required, the movable measuring jaw and the fixed measuring jaw are brought into contact by the drive of the horizontal electric slide rail 13. The image recognition device 23 identifies whether the movable measuring jaw and the fixed measuring jaw are in contact. After contact is completed, the lifting cylinder 25 is extended and retracted by controlling it, which drives the pressing shaft 26 to move downward and press the zeroing button on the electronic display screen to complete the zeroing operation of the caliper.
