[0022] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the content of the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model. It should also be noted that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings, rather than all the contents.

[0024] A cylinder support plate 7 is provided on one side of the operating table, a positioning cylinder 9 is provided on the cylinder support plate 7, a pressing positioning cylinder support plate 8 is provided between the cylinder support plate 7 and the positioning cylinder 9, and a positioning block is provided on the positioning cylinder 9, and the positioning block is arranged opposite to the opening of the limiting part, and the positioning block is driven by the positioning cylinder 9 to press the impact specimen on the limiting part;

[0025] A friction cylinder support plate 18 is arranged on the other side of the operating table, a friction cylinder 23 is arranged on the friction cylinder support plate 18, a friction base plate 12 is arranged on the friction cylinder 23, a friction shaft is arranged on the friction base plate 12, the friction shaft and the opening of the limit part are arranged opposite to each other, and under the drive of the friction cylinder 23, the top end of the friction shaft is stuck in the notch of the impact specimen.

[0026] The impact sample is placed on the placement part of the table 6, and the positioning cylinder 9 drives the positioning block to move horizontally to the right, pressing the impact sample against the limit block of the table 6. The friction cylinder 23 drives the friction shaft of the top stuck in the notch of the impact sample to reciprocate up and down, which can effectively remove the burrs of the notch of the impact sample to improve the clarity of the groove imaging, thereby improving its measurement results. Figures 4 to 5 , which is a comparison diagram of samples with unprocessed burrs measured by image and samples with processed burrs measured by image.

[0027] In the above preferred solution, the top of the friction shaft is V-shaped or U-shaped; that is, when the friction shaft is a V-shaped friction shaft 14, the notch corresponding to the top is the V-shaped notch 10 of the impact specimen. When the friction shaft is a U-shaped friction shaft 15, the notch corresponding to the top is the U-shaped notch 11 of the impact specimen. The top of the friction shaft fits the notch of the impact specimen, which can effectively remove the burrs of the notch of the impact specimen and improve the measurement accuracy.

[0028] In the above preferred solution, a spring is sleeved in the friction shaft and a top spring mounting plate 19 is passed through the end of the friction shaft through a suction cup rod 22. The top spring mounting plate 19 provides a stable support for the friction shaft and adds a buffer to elastic elements such as springs, thereby improving the stability and reliability of the friction shaft during operation. It should be noted that an adjusting nut for adjusting the spring pressure is also provided on the outside of the top spring mounting plate 19; and a nut for adjusting the initial depth position of the top of the friction shaft is also provided on the friction shaft.

[0029] In one preferred solution mentioned above, the friction shaft is also provided with a guide frame 13 which passes through the friction shaft to provide additional support and guidance for the friction shaft, thereby ensuring that the top of the friction shaft can always be stuck in the notch of the impact specimen, which greatly reduces the error caused by offset or shaking, thereby improving the deburring effect and further improving the measurement accuracy.

[0030] In the above preferred scheme, the positioning block includes a push-in-position block 16 and a press-in-position plate 20, and the press-in-position plate 20 is provided with a push-in-position block 16. The positioning cylinder 9 drives the press-in-position plate 20 to move horizontally to the right, and the press-in-position plate 20 drives the push-in-position block 16 to move horizontally to the right, so as to press the impact specimen onto the limit block of the table 6 to complete the fixation of the impact specimen.

[0031] In one preferred solution described above, sandpaper tightening plates 17 are provided on both sides of the friction shaft to compress the sandpaper wrapped on the friction shaft, thereby ensuring that the sandpaper maintains a constant tension on the friction shaft, thereby preventing the sandpaper from loosening or slipping during use and affecting the processing effect; at the same time, the sandpaper tightening plates 17 can be adjusted to replace worn or damaged sandpaper, thereby improving the maintenance convenience of the equipment.

[0032] In the above preferred solution, a rotating pressing support plate 21 is provided on the side of the table support plate 5, which can conveniently adjust the pressing force and angle of the table support plate 5. At the same time, since the pressing support plate can be rotated, it can be conveniently stored when not in use to save space.

[0033] In the above preferred scheme, the operating table includes a base plate 1, an aluminum profile rod 4, and a base plate 3. The aluminum profile rod 4 is installed on the base plate 1, and angle brackets 2 are respectively arranged on both sides of the aluminum profile rod 4 and located on the base plate 1. The upper end of the aluminum profile rod 4 is provided with the base plate 3, which increases the stability of the operating table and makes it less susceptible to external factors such as vibration or collision. At the same time, modular assembly is adopted to facilitate the assembly and disassembly of the operating table.

[0034] When the utility model works, the specific process is as follows:

[0035] Step 1: Place the impact specimen on the placement portion of the table 6 and on the corresponding U-groove (or V-groove) station, with the grooved surface facing the direction of the sandpaper tightening plate 17;

[0036] Step 2: The positioning cylinder 9 drives the positioning block 16 to move horizontally to the right, pressing the impact specimen against the limit block of the table 6;

[0037] Step 3: Wrap the U-shaped friction shaft 15 with sandpaper, keep the tension, and use the sandpaper pressing plate 17 to press the sandpaper on both sides of the U-shaped friction shaft 15, so that the sandpaper fits the tip of the U-shaped friction shaft 15 and forms a U shape (the same applies to the V shape);

[0038] Step 4: The friction cylinder 23 drives the friction base plate 12 to move the U-shaped friction shaft 15 wrapped with sandpaper vertically upward to the same height as the impact specimen (the same applies to the V-shaped one);

[0039] Step 5: Adjust the position and spring pressure of the U-shaped friction shaft 15 until its top is stuck in the U-shaped notch 11 of the impact specimen (the same applies to the V-shaped one);

[0040] Step 6: The friction cylinder 23 drives the friction base plate 12 to drive the U-shaped friction shaft 15 wrapped with sandpaper to do up and down reciprocating motion to achieve the deburring process.

[0041] When the robot places the impact sample on the table 6, the friction cylinder 23 is in the retracted position; when the robot leaves, the friction cylinder 23 extends, the left pressing cylinder 9 extends, the pressing sample contacts the friction plate, and the friction cylinder 23 retracts and retracts to remove the friction burrs. The burrs on the notch of the impact sample can be effectively removed with a high degree of automation, which ensures measurement accuracy while reducing work intensity.

[0042] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
