[0029] The clamping block 122 is configured as a single-sided clamping block or a double-sided clamping block. The multiple clamping blocks 122 configured on a base can all be single-sided clamping blocks or all be double-sided clamping blocks. Of course, it can also be a combination of single-sided clamping blocks and double-sided clamping blocks.

[0030] When the clamping block 122 is a single-sided clamping block, it has one clamping groove 123 ; when the clamping block 122 is a double-sided clamping block, it has two clamping grooves 123 , and the two clamping grooves 123 are respectively arranged on opposite sides of the clamping block 122 .

[0031] It should be specifically explained that the elastic clamping and material-taking mechanism 16 includes a cylinder 161, a second piston rod 162 connected to the cylinder 161, and a material receiver 163 arranged at the end of the second piston rod 162. The material receiver 163 is composed of a multi-petal arc-shaped clamping piece 1631, and the multi-petal arc-shaped clamping piece 1631 encloses an elastic clamping space 164 for clamping the rod material. The space size of the elastic clamping space 164 changes with the size of the clamped rod material.

[0032] At least two arc-shaped clips 1631 are provided, and the arc-shaped clips 1631 are metal springs. Preferably, the inner side of the end of the arc-shaped clip 1631 away from the second piston rod 162 has an arc to reduce resistance and facilitate the insertion of the rod.

[0033] It should be specifically explained that the milling mechanism 14 specifically includes a spindle box 141, a shaft 142 arranged in the spindle box 141, a tool 143 fixedly connected to one end of the shaft 142 toward the clamping and positioning mechanism 12, and a motor 144 for driving the shaft 142 to rotate. Among them, the tool 143 on the milling mechanism 14 located on one side of the frame 11 is a flat drill bit, and the tool 143 on the milling mechanism 14 located on the other side of the frame 11 is a hollow drill bit. The elastic clamping and material taking mechanism 16 and the milling mechanism 14 with the tool 143 being a hollow drill bit are arranged on the same side of the frame 11.

[0038] In actual use, first, the automatic clamping and conveying device 3 loads the bar blank to the clamping and positioning mechanism 12, and then the clamping and positioning mechanism 12 is driven by the first driving mechanism 13 to move the bar blank to the specified position, facing the hollow drill bit, and then the milling mechanism 14 starts to work, and with the cooperation of the second driving mechanism 15, drives the hollow drill bit to drill the bar blank to a specified depth. After the processing is completed, the hollow drill bit withdraws from the blank, and the clamping and positioning mechanism 12 is driven by the first driving mechanism 13 to move quickly again, so that the elastic clamping and material taking mechanism The material receiver 163 of 16 is facing the blank, and the material receiver 163 extends out to hold the tensile specimen blank which is still connected to the bar blank. At the same time, the milling mechanism 14 located on the other side works to drive the flat-head drill to process and separate the portion where the tensile specimen blank is connected to the bar blank. After the tensile specimen blank is separated from the bar blank, the elastic clamping and material taking mechanism 16 returns to its original position with the prepared tensile specimen blank, and the automatic clamping and feeding device 3 takes out the tensile specimen blank and sends it to the laser marking device 2 for coding, and places the coded tensile specimen blank on the finished product rack device 4.
