Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

As shown in the figure, a checker for quickly detecting the size of a part according to the present invention includes a measuring rod 1 and a support 2 supporting the measuring rod 1, and a measuring head 3 is arranged at the end of the measuring rod 1. The measuring rod 1 can move on the support member 2, the connecting rod 4 perpendicular to the measuring rod 1 is arranged on the measuring rod 1, the first sensing contact 5 and the second sensing contact are arranged on one side of the measuring rod 1 The connecting rod 4 is located in the middle of the first sensing contact 5 and the second sensing contact 6 .

Furthermore, the support member 2 is fixedly connected with a fixed rod 7 , the measuring rod 1 is connected with the fixed rod 7 through a spring 8 , and the spring 8 is partly sheathed on the outer periphery of the fixed rod 7 . By setting the fixed rod 7 and the spring 8, the support member 2 will move during measurement, and the spring 8 will be compressed during the movement. After the measurement is completed, the resilience of the spring 8 will help the support member 2 to reset.

Furthermore, the measuring rod 1 is provided with a protruding part 9, and the protruding part 9 is provided with a rotating shaft 10, and the connecting rod 4 can rotate around the rotating shaft 10. When the measuring rod 1 moves through the rotating shaft 10 , the connecting rod 4 will rotate around the rotating shaft 10 to contact the first sensing contact 5 or the second sensing contact 6 . Furthermore, the length of the connecting rod 4 is greater than the length of the protruding part 9. During the measurement, the measuring rod 1 moves to drive the connecting rod 4 to rotate, and the rotating range of the connecting rod 4 is larger, which is equivalent to amplifying the small size of the measuring rod 1. move.

Furthermore, the extension part 9 is provided with a return spring 11, and the return spring 11 helps the extension part 9 to reset after the measurement is completed.

Further, the support member 2 has a first horizontal plate 12 and a second horizontal plate 13 arranged in parallel, the first sensing contact 5 is arranged on the first horizontal plate 12, and the second sensing contact 6 Installed on the second horizontal plate 13, through the first horizontal plate 12 and the second horizontal plate 13, the first sensing contact 5 and the second sensing contact 6 can be fixed on one side of the measuring rod 1, and the fixing is simple, The fixed rod 7 is fixed on the first horizontal plate 12 , and the measuring rod 1 is connected to the fixed rod 7 through the second horizontal plate 13 .

Furthermore, the first sensing contact 5 is mounted on the first horizontal plate 12 through screws 14, and the second sensing contact 6 is mounted on the second horizontal plate 13 through screws 14, so the connection is simple. The positions of the first sensing contact 5 and the second sensing contact 6 can be adjusted as required.

Furthermore, the support 2 is fixed on a vertical bar 15 by a screw 14, the height of the support 2 is adjustable, the height of the support 2 can be adjusted by loosening the screw, and the support 2 is locked. can be fixed.

When the inspection tool of the present invention is in use, it is first necessary to adjust the corresponding position of the support member 2. The specific method is to set up the gauge block (the size is the middle size of the measured part, that is, the average of the maximum limit size and the minimum limit size) value) placed under the measuring rod 1, adjust the vertical height of the support 2, and lock the support 2 when the gauge block (not shown) comes into contact with the measuring head 3. Take off the gauge block under the measuring head 3, and put the gauge block rebuilt according to the minimum limit size of the part under the measuring rod 1. At this time, because the measured size is reduced, the measuring rod 1 drives the measuring head 3 to move down slightly, The connecting rod 4 rotates upward around the rotating shaft 10 to adjust the position of the first sensing contact 5 so that the first sensing contact 5 is in contact with the connecting rod 4 and the indicator light of the first sensing contact 5 is on. Take off the gauge block, and put the gauge block built according to the maximum limit size of the part under the measuring rod 1. At this time, due to the increase of the measured size, the measuring rod 1 drives the measuring head 3 to move slightly upward, and the connecting rod 4 circles The rotating shaft 10 rotates downward to adjust the position of the second sensing contact 6 so that the second sensing contact 6 is in contact with the connecting rod 4 and the indicator light of the second sensing contact 6 is on.

After the above adjustments, the adjustment of the inspection tool is completed. At this time, place the measured part 20 under the measuring rod 1 and make contact with the measuring head 3. If the indicator light of the first sensing contact 5 is on, it means that the size of the measured part is smaller than the minimum limit size of the part (unqualified). If the indicator light of the second sensing contact 6 is on, it means that the size of the measured part is larger than the maximum limit size of the part (unqualified). If the indicator lights of the first sensing contact 5 and the second sensing contact 6 are both on and off, then the size of the measured part is between the maximum limit size and the minimum limit size, and it is qualified.

If the shape of the measured part 20 is a spherical part, the spherical measuring head 3 under the measuring rod 1 can be removed (the measuring head 3 and the measuring rod 1 are connected by threads), and replaced with a flat measuring head 3 (measuring cap) Just can measure the size of the spherical part 20, the adjustment method of the checking fixture is the same as the above-mentioned method.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made. It should also be regarded as the protection scope of the present invention.
