Description

Technical Field

[0001] The utility model relates to a calibrator, in particular to a full-automatic calibrator for an automatic focusing indicator, belonging to the technical field of indicator instruments. Background Art

[0002] A dial indicator is a precision measuring instrument, also known as a caliper indicator. Its measurement principle is based on mechanical force, using a pair of needles: one fixed to the dial and the other movable, allowing readings to be taken on the dial scale. To measure an object, the object is placed between the fixed and movable needles, and the movable needle is then moved close to the surface. The size of the object is determined by the position of the movable needle on the scale.

[0003] After searching, Chinese patent publication number CN212988419U discloses a grating indicator calibrator, comprising a calibrator body, a wearing device disposed below the calibrator body, and a connecting assembly securing the calibrator body and the wearing device. The wearing device comprises an upper plate and a lower plate adjacent to each other, the rear sides of the upper and lower plates being hingedly connected, and two first symmetrical grooves are disposed on the front side of the upper end of the lower plate. This utility model allows for hands-free operation when a grating indicator calibrator cannot be placed, making it convenient to use.

[0004] Although the above solution can be operated without using both hands and is easy to use, the calibration instrument in the above patent is difficult to protect the indicator. During calibration, the indicator may be damaged or the data may be inaccurate due to accidental touching of the indicator by a person. Therefore, we provide an automatic calibration instrument for an autofocus indicator to solve the above problems. Utility Model Content

[0026] The embodiment of the utility model provides a fully automatic calibrator for an automatic focusing indicator.

[0027] See also Figure 1 and Figure 2 , including a fully automatic calibrator 1, an indicator 2 and a protective support shell 3. The fully automatic calibrator 1 and the indicator 2 are both existing technologies and will not be described in detail. The fully automatic calibrator 1 can detect the indicator 2 and transmit the detection data to an external computer.

[0028] See also Figure 1 The protective support shell 3 is slidably connected to the external guide rail 18 through the track bar. The setting of the protective support shell 3 can protect its internal components. The external guide rail 18 is fixedly connected to the upper surface of the support placement platform 19. The setting of the external guide rail 18 can effectively limit the protective support shell 3, ensuring that the protective support shell 3 can only move in the specified direction and ensure stability during the movement.

[0029] See also Figure 1 The lower surface of the supporting and placing platform 19 is fixedly provided with supporting balancing legs 20. There are four groups of supporting balancing legs 20. The four groups of supporting balancing legs 20 are evenly distributed on the lower surface of the supporting and placing platform 19. The purpose of setting four groups of supporting balancing legs 20 is to effectively support the supporting and placing platform 19 and ensure the balance of the supporting and placing platform 19, so that the supporting and placing platform 19 is not prone to tilting.

[0030] See also Figure 1 、 Figure 3 and Figure 4 A fully automatic calibrator 1 is fixedly installed on the upper surface of the supporting platform 19, and a unidirectional DC motor 4 is fixedly installed on one side of the protective support shell 3. The output shaft of the unidirectional DC motor 4 is fixedly connected to one end of the first linkage plate 5. The unidirectional DC motor 4 is a prior art and will not be described in detail. The setting of the unidirectional DC motor 4 can effectively drive the first linkage plate 5 to rotate, so that the subsequent components can move synchronously.

[0031] See also Figure 3 and Figure 4 The other end of the first linkage plate 5 is rotatably connected to one end of the second linkage plate 6, and the other end of the second linkage plate 6 is connected to the linkage support bearing 7. The cooperation between the first linkage plate 5 and the second linkage plate 6 can promote the movement of the linkage support bearing 7, so that the linkage support bearing 7 drives the subsequent special-shaped force-bearing plate 8 to move.

[0032] See also Figure 3 and Figure 4The linkage support bearing 7 is fixedly connected to the special-shaped force-bearing plate 8, the special-shaped force-bearing plate 8 is fixedly connected to the guide module 11, the guide module 11 is slidably set in the groove opened by the guide track plate 12, and the guide track plate 12 is fixedly set inside the protective support shell 3. The setting of the guide module 11 can effectively move upward in the direction of the groove of the guide track plate 12 to ensure the stability of the special-shaped force-bearing plate 8.

[0033] See also Figure 3 and Figure 4 The groove opened in the guide track plate 12 is slidingly provided with a linkage support bearing 7, and the linkage support bearing 7 will be restricted by the guide track plate 12. When the linkage support bearing 7 moves to the specified position, it will enter the bifurcation of the groove of the guide track plate 12 due to the influence of the force direction, so that the special-shaped force plate 8 is acted upon by the mounting plate 9, so that the pick-up and placement panel 10 changes from a horizontal state to a vertical state, and the special-shaped force plate 8 is fixedly connected to the pick-up and placement panel 10 through the mounting plate 9.

[0034] See also Figure 2 and Figure 5 An external positioning cylinder 13 is fixedly provided on the upper surface of the pick-up and placement panel 10. The setting of the external positioning cylinder 13 can effectively limit the internal components thereof, thereby ensuring the vertical lifting and lowering of the internal components thereof. A tough spring 17 is fixedly provided inside the external positioning cylinder 13. One end of the tough spring 17 is fixedly connected to the upper surface of the restricted disc 14. The setting of the tough spring 17, utilizing the elastic characteristics of the tough spring 17 itself, can effectively push the restricted disc 14 to reset.

[0035] See also Figure 2 and Figure 5 A restricted disc 14 is slidingly provided inside the external position control cylinder 13. The restricted disc 14 is fixedly connected to the U-shaped pressure module 16 through a linkage column 15. The U-shaped pressure module 16 is in contact with the indicator gauge 2. The close cooperation between the linkage column 15 and the U-shaped pressure module 16 can effectively apply pressure to the indicator gauge 2, thereby ensuring the stability of the indicator gauge 2. The interior of the U-shaped pressure module 16 is filled with sponge to avoid excessive pressure on the indicator gauge 2, which may cause damage to the indicator gauge 2.

[0036] Working principle: The one-way DC motor 4 is started to work by the control panel set on the surface of the full-automatic tester 1, which drives the second linkage plate 6 on the one-way DC motor 4 to move, so that the linkage support bearing 7 slides in the groove opened by the guide track plate 12. At the same time, the linkage support bearing 7 will also drive the special-shaped force plate 8 to move, and the special-shaped force plate 8 drives the guide module 11 to slide in the groove opened by the guide track plate 12. When the linkage support bearing 7 moves to the bifurcation of the groove of the guide track plate 12, it is affected by the force of the second linkage plate 6, so that the linkage support bearing 7 enters the groove of the bifurcation of the guide track plate 12, so that the special-shaped force plate 8 pushes the pick-up and placement panel 10 to rise a distance through the mounting plate 9, and then rotates, so that the pick-up and placement panel 10 is transformed from a horizontal state to a vertical state, and then the indicator 2 is placed at the designated position in the protective support shell 3. Similarly, the pick-up and placement panel 10 is reset, so that the protective support shell 3 forms a relatively closed space. During the resetting process of the pick-up and placement panel 10, the U-shaped pressure module 16 is also reset through the external position control cylinder 13, so that the U-shaped pressure module 16 contacts the indicator 2, and under the influence of the reaction force, the linkage column 15 drives the restricted disc 14 to slide in the external position control cylinder 13, compressing the toughness spring 17. Under the action of the elasticity of the toughness spring 17 itself, the U-shaped pressure module 16 applies pressure to the indicator 2, ensuring the stability of the indicator 2. Finally, the protective support shell 3 is pushed by external force to slide in the two sets of external guide rails 18, so that the indicator 2 is connected to the fully automatic calibrator 1. The indicator 2 can be tested by the fully automatic calibrator 1, thereby protecting the indicator 2 and ensuring that it will not be disturbed by the outside world during the testing process.
