Referring to FIGS. 1-5 , the above-mentioned fixture for the vernier 13 includes a vernier body 131 , an outer measuring claw 132 arranged on one side of the vernier body 131 , and an inner measuring claw 133 arranged on the opposite side of the vernier body 131 .

The fixture includes a base 1 , a cover plate 2 arranged on the base 1 , and a hollow cavity opened between the base 1 and the cover plate 2 .

The cursor 13 is placed horizontally on the upper surface of the cover plate 2. The fixture also includes a first reference member 3 and a second reference member 4 which are arranged on the cover plate 2 and are used to respectively interfere with two adjacent sides of the cursor 13. The first reference member 3 and the second reference member 4 are detachably arranged on the cover plate 2, which is convenient for fine-tuning or replacement according to different types of cursors 13.

The fixture also includes a movable first sliding member 5 disposed in the hollow cavity for resisting the cursor 13, a movable second sliding member 6 disposed in the hollow cavity for resisting the vernier 13, and a driving mechanism arranged on the base 1 for driving the movement of the first sliding member 5. The first sliding member 5 and the first reference member 3 are located on two different sides of the vernier 13 , and the second sliding member 6 and the second reference member 4 are located on different two sides of the vernier 13 . Through this setting, first fix the two sides of the cursor 13 , and then fix the other two sides, so that the cursor 13 is firmly clamped on the cover plate 2 .

In this embodiment, the driving mechanism includes a cylinder body 7 , and a push rod 8 arranged in the cylinder body 7 that moves along the direction of its own length extension. The output end of the push rod 8 is connected to the first slider 5 . The push rod 8 is integrally located in the hollow cavity. It can effectively protect the push rod 8 and prevent debris from entering it and affecting its service life.

Apparently, the base 1 is provided with a first space 9 for matching the sliding of the first sliding member 5, and the cover plate 2 is provided with a second space 10 for matching the sliding of the first sliding member 5 therein; the base 1 is provided with a third space 11 for matching the sliding of the second sliding member 6 therein, and the cover plate 2 is provided with a fourth space 12 for matching the sliding of the second sliding member 6 therein.

The sliding direction of the first sliding member 5 is perpendicular to the direction in which it collides with the contacting surface on the vernier 13; the sliding direction of the second sliding member 6 is also perpendicular to the direction in which it is colliding with the contacting surface on the vernier 13; the sliding direction of the first sliding member 5 and the sliding direction of the second sliding member 6 are perpendicular to each other, and both are located in the horizontal plane.

The jig also includes a linkage mechanism arranged between the first slider 5 and the second slider 6 for driving the second slider 6 to approach or move away from the cursor 13 synchronously when the first slider 5 approaches or moves away from the cursor 13 .

The first slider 5 includes a movable first body 51 disposed in the hollow cavity for abutting against the cursor 13 , and a connecting block 52 disposed on the side of the first body 51 close to the second slider 6 . The top of the first body 51 is higher than the cover body, and is used for resisting the cursor 13 ;

The second sliding member 6 includes a movable second body 61 disposed in the hollow cavity for abutting against the cursor 13 . The top of the second body 61 is higher than the cover, and is used for resisting the cursor 13;

The linkage mechanism includes a guide groove 53 provided on the connecting block 52 and a guide piece 62 protruding from the bottom of the second body 61 .

In this embodiment, the guide groove 53 is a rectangular groove, and the guide member 62 is a rectangular block with the same width and a shorter length. Through the movement of the rectangular block in the rectangular groove, the second sliding block and the first sliding block move synchronously. In this embodiment, the extending direction of the guide groove 53 is at an angle of 45 degrees to the sliding direction of the first sliding member 5 and the sliding direction of the second sliding member 6 .

The linkage mechanism has a compressed state and an open state;

When the linkage mechanism is in the compressed state, the driving mechanism drives the first slider 5 to the left (see FIG. 2, the left side referred to here is the left side in FIG. 2) to slide against the cursor 13, and the guide 62 drives the second slider 6 downward under the drive of the guide groove 53 (see FIG. 2, the bottom here is the bottom in FIG. 2) to slide against the cursor 13;

When the linkage mechanism is in the open state, the driving mechanism drives the first sliding member 5 to the right (see FIG. 2 , the right side referred to here is the right side in FIG. 2 ) to slide away from the cursor 13 , and the guide member 62 drives the second sliding member 6 upward (see FIG. 2 , the upper side referred to here is the upper side in FIG. 2 ) to slide away from the cursor 13 driven by the guide groove 53 .

The working process of the present embodiment is set forth below in detail:

Place the cursor 13 on the cover plate 2 so that its two sides touch the first reference member 3 and the second reference member 4 respectively, and then the push rod 8 is retracted, so that the first slider 5 slides to the left and touches the cursor 13. At this time, the guide member 62 drives the second slider 6 to slide downward to contact the cursor 13 under the drive of the guide groove 53; the clamped cursor 13 is processed. Driven by the slot 53 , the second slider 6 is driven to slide upwards away from the cursor 13 ; the cursor 13 is taken out.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention shall fall within the protection scope of the present invention.
