Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0030] Next, in combination with Figures 1 to 5 , the embodiments of the present application will be described.

[0031] According to an embodiment of the present application, a clamping tooling is provided, including: a base 1, a fixing plate 2, a first clamping plate 3, a driving mechanism 4 and a second clamping plate 5;

[0032] Specifically, the fixing plate 2 is fixed on the base 1; the first clamping plate 3 is detachably connected to the fixing plate 2, and a positioning groove 301 for positioning a sample is formed on the first clamping plate 3; the driving mechanism 4 is installed on the base 1; the second clamping plate 5 is installed at the driving end of the driving mechanism 4, the second clamping plate 5 is arranged corresponding to the first clamping plate 3, and a clamping gap 6 is formed therebetween, and the driving end of the driving mechanism 4 can telescopically move to drive the second clamping plate 5 to approach or move away from the first clamping plate 3.

[0033] Install the sample on the positioning groove 301 to position the sample. The sample is located within the clamping gap 6. Control the driving mechanism 4 to operate. The driving end of the driving mechanism 4 drives the second clamping plate 5 to approach the first clamping plate 3 until the second clamping plate 5 and the first clamping plate 3 clamp the sample. By driving the second clamping plate 5 to move through the driving mechanism 4 to control the distance between the first clamping plate 3 and the second clamping plate 5 to clamp or release the sample, the working efficiency is improved and the labor intensity of workers is reduced. The first clamping plate 3 is detachably connected to the fixing plate 2 and can be replaced for different samples, improving the applicable range of the clamping tooling.

[0034] In one embodiment, as Figure 1 and Figure 3 shown, on the side of the first clamping plate 3 opposite to the fixing plate 2, a threaded connection hole is provided. The fixing plate 2 is provided with a through hole corresponding to the threaded connection hole. The connecting bolt 7 passes through the through hole and is screwed with the threaded connection hole. The connecting bolt 7 is screwed with the threaded connection hole to fix the first clamping plate 3 on the fixing plate 2. When clamping different samples, different first clamping plates 3 are replaced to adapt to different samples. The detachable connection is formed by the way of the connecting bolt 7 and the threaded connection hole, with a simpler structure and more convenient operation.

[0035] In a specific embodiment, the fixing plate 2 can be provided with through holes at multiple positions, capable of adjusting the position of the first clamping plate 3 on the fixing plate 2 to adjust the position of the sample.

[0036] In one embodiment, as Figures 1 to 2 shown, it further includes a limit pin 8. The limit pin 8 is slidably connected to the second clamping plate 5, and the limit pin 8 can be inserted into the positioning notch provided on the sample. After placing the sample on the positioning groove 301, the limit pin 8 is inserted into the positioning notch on the sample to fix the sample at the corresponding position. In this way, both hands can be liberated, and there is no need to hold the sample by hand to fix it at the corresponding position, preventing the hand from being injured when the second clamping plate 5 approaches the first clamping plate 3 to clamp the sample.

[0037] In one embodiment, as Figures 1 to 2As shown, it further includes a guiding block 9. The guiding block 9 is connected to the second clamping plate 5. A guiding groove 901 is formed on a side surface of the guiding block 9 opposite to the second clamping plate 5. The guiding groove 901 penetrates along the moving direction of the driving end of the driving mechanism 4. The limiting pin 8 is slidably connected to the guiding groove 901. The limiting pin 8 is slidably connected within the guiding groove 901 and is arranged corresponding to the positioning groove 301. When it is necessary to limit the sample, the limiting pin 8 slides along the moving direction of the driving end of the driving mechanism 4, approaches the sample, and inserts into the positioning notch formed on the sample, positioning the sample on the positioning groove 301. The driving end of the driving mechanism 4 drives the second clamping plate 5 to approach the first clamping plate 3, reducing the clamping gap 6. As the clamping gap 6 reduces, the limiting pin 8 can slide in a direction away from the first clamping plate 3, but during the sliding process, the limiting pin 8 is always inserted into the positioning notch. After the first clamping plate 3 and the second clamping plate 5 clamp the sample, the limiting pin 8 is pulled out of the positioning notch.

[0038] In one embodiment, as Figure 5 shown, limiting protrusions are provided at both ends of the limiting pin 8. The limiting protrusion closer to the first clamping plate 3 can be inserted into the positioning notch. Limiting protrusions are provided at both ends of the limiting pin 8, which can prevent the limiting pin 8 from sliding out of the guiding block 9.

[0039] In one embodiment, as Figure 2 and Figure 4 shown, the guiding block 9 is provided with at least one mounting hole, and the second clamping plate 5 is provided with threaded fixing holes corresponding to the mounting holes. The fixing bolt 10 passes through the mounting hole and is screwed into the threaded fixing hole. The fixing bolt 10 is screwed into the threaded fixing hole to fix the guiding block 9 on the second clamping plate 5. The guiding groove 901 and the second clamping plate 5 form a guiding hole, which is convenient for the sliding connection with the limiting pin 8.

[0040] It should be noted that the limiting pin 8 is first installed in the guiding groove 901, and then the guiding block 9 is fixed on the second clamping plate 5 through the fixing bolt 10. The limiting protrusions at both ends of the limiting pin 8 can prevent the limiting pin 8 from sliding out of the limiting groove.

[0041] It should be further noted that, as Figure 2 and Figure 4 shown, the guiding block 9 is installed on the top of the second clamping plate 5.

[0042] In one embodiment, it further includes a fixing block 11. The fixing block 11 is connected to the base 1. The fixing block 11 is provided with a through hole. The driving mechanism 4 is installed on the fixing block 11, and its driving end passes through the through hole and is connected to the second clamping plate 5. Installing the driving mechanism 4 on the fixing block 11 is more convenient.

[0043] It should be further explained that, as Figure 1As shown, the fixed block 11 is fixed on the base 1, and the fixed block 11 and the fixed plate 2 are arranged opposite to each other, facilitating the relative arrangement of the first clamping plate 3 and the second clamping plate 5 to form a clamping gap 6.

[0044] In a specific embodiment, the fixed plate 2, the fixed block 11 and the base 1 are integrally formed.

[0045] In one embodiment, as Figure 1 shown, it further includes a connecting plate 12 and a plurality of connecting columns 13. One side surface of the connecting plate 12 is mounted on the driving end of the driving mechanism 4, and the other side surface is connected to the plurality of connecting columns 13. The other ends of the plurality of connecting columns 13 are connected to the second clamping plate 5. The plurality of connecting columns 13 can improve the connection strength of the second clamping plate 5 and make it more stable when moving.

[0046] In one embodiment, the driving mechanism 4 is a driving cylinder, and the piston rod of the driving cylinder passes through the through hole and is connected to the connecting plate 12. Driven by the cylinder, the driving method is more direct, with fast response speed and high efficiency.

[0047] Furthermore, the driving cylinder is connected with an air pipe, and a pressure regulating valve is connected to the air pipe, which can adjust the output pressure of the driving cylinder to prevent the pressure from being too large or too small.

[0048] Even further, a safety check valve is connected to the air pipe, which can prevent the piston rod of the driving cylinder from retracting when the air pressure in the air pipe decreases, and the sample cannot be clamped.

[0049] In one embodiment, it further includes a pressure sensor, and the pressure sensor is installed on the second clamping plate 5 corresponding to the positioning groove 301. The pressure sensor is used to monitor the pressure on the sample in real time, preventing the pressure from being too small to clamp the sample and also preventing the pressure from being too large to damage the sample.

[0050] Next, taking an embodiment as an example, combined with Figures 1 to 5 to comprehensively elaborate on the above all solutions.

[0051] The telescopic rod of the driving cylinder drives the second clamping plate 5 to move away from the first clamping plate 3, increasing the distance of the clamping gap 6. The sample is installed in the positioning groove 301, and the limit pin 8 is adjusted. One end of the limit pin 8 is inserted into the positioning notch opened on the sample, so that the sample can be positioned in the positioning groove 301, liberating the hands of the worker, without the need to always hold it by hand before the second clamping plate 5 clamps the sample, and it can prevent the second clamping plate 5 from pinching the hand.

[0052] The driving cylinder drives the second clamping plate 5 to approach the first clamping plate 3, the clamping gap 6 is reduced, and the limit pin 8 is simultaneously pushed and moves away from the first clamping plate 3. However, one end of the limit pin 8 still remains inserted in the positioning notch to maintain the position of the sample in the positioning groove 301. When the second clamping plate 5 and the first clamping plate 3 clamp the sample, the pressure sensor can monitor the pressure between the first clamping plate 3 and the second clamping plate 5. After reaching the appropriate pressure, the pressurization is stopped. Subsequently, the limit pin 8 is pulled out of the positioning notch, and at the same time, the safety check valve is activated. The safety check valve can prevent gas backflow, prevent the piston rod of the driving cylinder from retracting, maintain the appropriate pressure, and at the same time can prevent accidents until the test on the sample is completed.

[0053] Although the embodiments of the present application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations all fall within the scope defined by the appended claims of the present application.
