Detailed ways

The present application will be further described in detail below in conjunction with Figures 1-4.

The embodiment of the present application discloses a length measuring device for a conductive rod.

Referring to Figures 1 and 2, a length measuring device for a conductive rod includes a base 1, and the base 1 is provided with an electronic dial indicator 3. The electronic dial indicator 3 includes a meter body 31 , a connecting tube 32 and a probe 33 . The connecting tube 32 is fixedly installed on the watch body 31 , and the probe 33 elastically expands and contracts on the connecting tube 32 . The elastic expansion and contraction causes the probe 33 to be squeezed and retracted into the connecting tube 32. After the probe 33 is released, the probe 33 will automatically extend from the connecting tube 32. The meter body 31 measures based on the length of the probe 33 contracted to the connecting tube 32 .

Referring to Figures 1 and 2, two clamping blocks 4 are fixedly installed on one side wall of the base 1. The two clamping blocks 4 have clamping grooves 5 for placing the connecting pipes 32 on each side facing each other. Both clamping blocks 4 are elastic, and the two clamping blocks 4 are made of plastic or metal with low elasticity.

After the two clamping blocks 4 are spread apart, the connecting pipe 32 is placed in the two clamping grooves 5 . Then the clamp block 4 is released, and the clamp block 4 clamps the connecting pipe 32 under the action of elastic force, so that the electronic dial indicator 3 is installed on the base 1 . After the electronic dial indicator 3 is out of power, you can open the clamping block 4, then take out the dead electronic dial indicator 3 and send it for charging, and put the charged electronic dial indicator 3 back into the two clamping blocks 4. Tight, thereby reducing the situation that the entire length measuring device cannot be used after the electronic dial indicator 3 is out of power.

Referring to Figures 1 and 2, bolts 6 are provided between the two clamping blocks 4. Both clamping blocks 4 are provided with through holes 7 for the bolts 6 to pass through. The through holes 7 are located higher than the clamping groove 5. After the two clamping blocks 4 clamp the connecting pipe 32, the bolts 6 are passed through the through holes 7 and then tightened, which is beneficial to further improving the clamping force of the two clamping blocks 4 to clamp the connecting pipe 32.

In the embodiment of the present application, each clamping block 4 has only one clamping groove 5, the conductive rod is tubular, and the wall thickness of the conductive rod is large. The diameter difference between conductive rods of different sizes is generally small, so for conductive rods of different diameters, the probe 33 can be pressed against the end of the conductive rod without being inserted into the conductive rod.

In another embodiment, each clamping block 4 has at least two clamping slots 5 , the clamping slots 5 on each clamping block 4 are spaced apart along the height direction, and the height of each clamping slot 5 is lower than the through hole. 7 at the height. By providing multiple clamping grooves 5, the height of the probe 33 can be adjusted conveniently. This facilitates the probe 33 to be abutted against the ends of different conductive rods.

Referring to FIG. 3 , the top side of the base 1 is provided with a positioning groove 8 for placing the conductive rod. The positioning groove 8 is provided along the length direction of the probe 33 . When placing the conductive rod on the base 1, let the conductive rod enter the inside of the positioning groove 8, so as to facilitate the alignment of the conductive rod and the probe 33, and then facilitate the probe 33 to abut the end of the conductive rod.

The distance between the opposite side walls of the positioning groove 8 gradually decreases from the notch of the positioning groove 8 to the bottom of the groove, thereby facilitating the positioning groove 8 for conductive rods of different diameters to enter, and thereby facilitating the length measuring device to measure conductive rods of different sizes. Take measurements.

Referring to Figures 3 and 4, a support block 9 is provided on the top side of the base 1, and a slider 10 is fixedly installed on the bottom side of the support block 9. The base 1 has a hollow structure, and a sliding port 11 for the slider 10 to slide is provided at the bottom of the positioning groove 8. The sliding port 11 is connected to the inside of the base 1. The sliding opening 11 is arranged along the length direction of the probe 33 . The probe 33 faces the support block 9 , and the slider 10 slides inside the sliding opening 11 , thereby allowing the support block 9 to move closer to or away from the probe 33 .

Referring to FIGS. 3 and 4 , a limiter block 12 is fixedly installed on the side of the slider 10 away from the support block 9 , and the limiter block 12 abuts against the inner top wall of the base 1 . By the limiting block 12 being engaged with the inner top wall of the base 1 , the sliding block 10 is reduced from being pulled upward from the sliding opening 11 .

Referring to FIGS. 3 and 4 , the base 1 is provided with a limiting component 13 , and the limiting component 13 includes a nut 131 and a screw 132 . The nut 131 is fixedly installed on the side wall of the base 1 away from the clamping block 4 , and the screw rod 132 is threaded through the nut 131 . The screw rod 132 also penetrates the side wall of the base 1 and abuts against the limiting block 12 .

Through the cooperation between the screw rod 132 and the nut 131, the screw rod 132 is rotated, thereby adjusting the length of the screw rod 132 entering the inside of the base 1. When the length of the screw rod 132 extending into the interior of the base 1 increases, the screw rod 132 pushes the limit block 12 to move toward the clamping block 4. The limit block 12 drives the slider 10 to slide inside the slide port 11 and then drives the support block 9 to approach the probe 33. . When the length of the screw rod 132 extending into the interior of the base 1 decreases, the distance between the screw rod 132 and the limiting block 12 increases, and then the support block 9 is directly pushed away from the probe 33 . The distance between the support block 9 and the probe 33 is adjustable, thereby facilitating the length measuring device to detect conductive rods of different sizes.

A positioning block 2 is fixedly installed on the side of the base 1 close to the probe 33. Place the conductive rod into the positioning slot 8 , then align one end of the conductive rod with the probe 33 , and align the other end of the conductive rod with the positioning block 2 . The positioning block 2 will be inserted into the inside of the conductive rod, thereby reducing the rolling of the conductive rod on the base 1.

The top side of the base 1 is provided with a access opening 14 for the limiting block 12 to enter and exit. The access opening 14 is connected with the inside of the base 1 , and the access opening 14 is connected with the end of the sliding port 11 away from the clamping block 4 . When replacing conductive rods with different diameters for inspection, according to the shape and size of the end of the conductive rod facing the support block 9, select a positioning block 2 with a corresponding shape on the support block 9. Then the limiting block 12 is allowed to enter the inside of the base 1 from the access opening 14, thereby facilitating the replacement of different positioning blocks 2.

The implementation principle of a length measuring device for a conductive rod in the embodiment of the present application is as follows: according to the shape and size of the end of the conductive rod to be detected facing the support block 9, select the positioning block 2 with a corresponding shape on the support block 9. Then let the limiting block 12 enter the inside of the base 1 from the access opening 14, and then push the support block 9 to move, so that the slide block 10 enters the inside of the sliding opening 11, so that the support block 9 is installed on the base 1.

Then screw the screw rod 132 into the nut 131 so that the screw rod 132 abuts the limiting block 12 to push the support block 9 closer to the probe 33 . When the distance between the probe 33 and the support block 9 is less than the standard length of the conductive rod to be detected, stop rotating the screw rod 132 . The standard length of the conductive rod is the length of the conductive rod that needs to be produced.

Afterwards, the squeeze probe 33 is retracted into the connecting tube 32 , and the conductive rod to be detected is placed inside the positioning groove 8 . Then push the conductive rod to move toward the support block 9 so that the positioning block 2 is inserted into one end of the conductive rod. The positioning block 2 restricts the conductive rod from rolling on the base 1 .

After the positioning block 2 is inserted into one end of the conductive rod, the probe 33 is released. The probe 33 extends from the connecting tube 32 and then abuts against the end of the conductive rod away from the support block 9 . Then, the meter body 31 displays the length of the conductive rod according to the length of the probe 33 extending out of the connecting tube 32, thereby reducing the difficulty of reading the length of the conductive rod and thereby improving the efficiency of measuring the conductive rod.

There are two situations in which the electronic dial indicator 3 measures the length of the conductive rod: one is to pre-enter the distance between the support block 9 and the probe 33 into the electronic dial indicator 3 when the probe 33 does not shrink in the connecting tube 32 , then the display body 31 will display the sum of the distance between the support block 9 and the probe 33 that has not retracted the connecting tube 32 plus the length of the probe 33 contracted to the connecting tube 32 . The other is that the electronic dial indicator 3 directly displays the length of the probe 33 retracting the connecting pipe 32, and then manually calculates the distance between the support block 9 and the probe 33 that has not retracted the connecting pipe 32 plus the retracted probe 33. The length of the connecting tube 32.

The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be covered by the scope of protection of the present application. Inside.
