[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example 1, referring to Figures 1-9 This is the first embodiment of the present invention. This embodiment provides a clamping and detection device, including a tooling part 1, including a tooling plate 11, a first hydraulic cylinder 12, a second hydraulic cylinder 13, a third hydraulic cylinder 14, a fourth hydraulic cylinder 8, and a mounting mechanism 2. The first hydraulic cylinder 12, the second hydraulic cylinder 13, the third hydraulic cylinder 14, and the fourth hydraulic cylinder 8 are all fixed to the top of the tooling plate 11.

[0033] The connecting component 3 includes four pressure plates 31, four hinge frames 32, and four hinge blocks. One end of each of the four pressure plates 31 is hinged to the telescopic parts of the first hydraulic cylinder 12, the second hydraulic cylinder 13, the third hydraulic cylinder 14, and the fourth hydraulic cylinder 8, respectively. The four hinge blocks are fixed to the surfaces of the first hydraulic cylinder 12, the second hydraulic cylinder 13, the third hydraulic cylinder 14, and the fourth hydraulic cylinder 8, respectively. One end of each of the four hinge frames 32 is hinged to the four pressure plates 31, and the other end is hinged to the hinge blocks.

[0034] The detector 5 includes three product support blocks 56, which are all fixed to the top of the tooling plate 11 and located below the extension plate 31 of the second cylinder 13, the first cylinder 12 and the fourth cylinder 8, respectively.

[0035] Through the detector 5, when a product is clamped in place, three sides of the bottom of the product block the air holes 51 on the product support blocks 56, and at this time the air pressure sensor 55 can detect a stable air pressure value in the pipeline. If the clamping is not in place, the air holes 51 are not completely blocked, the air pressure value detected by the air pressure sensor 55 will change, and meanwhile the operator can also hear the "hissing" air leakage sound. This dual detection method greatly improves the accuracy and reliability of the judgment whether clamping is in place, effectively avoids processing errors caused by improper clamping, and guarantees the processing quality of the product.

[0036] Specifically, the detector 5 further comprises a first three-way pipe 53, a second three-way pipe 54 and a two-way pipe 52. The air holes 51 are formed on the product support blocks 56, three round holes are opened on the tooling plate 11 and communicate with the air holes 51 of the three product support blocks 56. One end of the first three-way pipe 53, one end of the second three-way pipe 54 and one end of the two-way pipe 52 are all fixed to the bottom of the tooling plate 11 and cover the round holes, and the air pressure sensor 55 is installed on each of the first three-way pipe 53, the second three-way pipe 54 and the two-way pipe 52.

[0037] An external air source pipeline delivers air into the first three-way pipe 53, and the air is delivered into the three product support blocks 56 through the first three-way pipe 53, a second pipeline, the second three-way pipe 54, a first pipeline and the two-way pipe 52. Since three sides of the bottom of the product block the air holes 51, the air pressure sensors 55 detect the air pressure change in the pipeline, and whether the product is clamped in place is judged according to the air pressure change. If the product is not clamped in place, the "hissing" air leakage sound can be heard, and meanwhile the air pressure value is also transmitted to an external controller, which triggers an alarm through a buzzer, and an external CNC machine works when the product is in place.

[0038] Specifically, the mounting mechanism 2 comprises two vertical plates 21 and two connecting frames 22. The two vertical plates 21 are both fixed to the bottom of the tooling plate 11 by screws, the two connecting frames 22 are respectively fixed to the bottoms of the two vertical plates 21, a middle-shaped moving slot is formed on the connecting frame 22, a middle-shaped moving plate 23 is slidably connected to the inner wall of the moving slot, two mounting plates 25 are arranged on one side of the moving plate 23, and a through hole is formed on the mounting plate 25.

[0039] The overall installation can be facilitated through the two mounting plates 25 in the mounting mechanism 2.

[0040] Specifically, the mounting mechanism 2 further comprises two first bolts 24, the two first bolts 24 are respectively in threaded connection with the two connecting frames 22, a first bearing is fixedly arranged on one side of the moving plate 23, and one end of the first bolt 24 is fixedly connected with the inner ring inner wall of the first bearing.

[0041] Rotating the two first bolts 24, since one end of the first bolt 24 is fixedly connected to the inner wall of the first bearing inner ring on one side of the movable plate 23, and the first bolt 24 is threadedly connected to the connecting frame 22, the position of the movable plate 23 in the movable groove can be adjusted. The movement of the movable plate 23 drives the movement of the mounting plate 25, and the mounting plate 25 is adjusted left and right.

[0042] The first hydraulic cylinder 12, the second hydraulic cylinder 13, the fourth hydraulic cylinder 8, the third hydraulic cylinder 14, the air pressure sensor 55, the floating cylinder 6, and the sequence valve 7 are all existing technologies. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0043] Example 2, refer to Figures 1-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0044] Specifically, two grooves 26 are provided on one side of the movable plate 23, and a second bearing is embedded in both sides of the movable plate 23. A second bolt 27 is fixedly installed on the inner wall of the inner ring of the second bearing. One end of the second bolt 27 is rotatably installed with one side of the inner wall of the groove 26. A connecting block 28 is slidably connected to one side of the inner wall of each of the two grooves 26. The second bolt 27 is threadedly connected to the connecting block 28. One side of each of the two connecting blocks 28 is fixedly connected to one side of each of the two mounting plates 25.

[0045] Rotate the second bolt 27. The rotation of the second bolt 27 causes the connecting block 28 and the mounting plate 25 to move in the direction of the groove 26, adjusting the position of the mounting plate 25 to align with the mounting hole of the installation position.

[0046] Specifically, a first pipe is fixedly installed at the other end of the two-way pipe 52, one end of the first pipe is fixedly connected to one end of the second three-way pipe 54, a second pipe is fixedly installed at one end of the second three-way pipe 54, and one end of the second pipe is fixedly connected to one end of the first three-way pipe 53.

[0047] The first and second pipes facilitate the connection between the two-way pipe 52, the first three-way pipe 53, and the second three-way pipe 54.

[0048] Specifically, a sequence valve 7 is fixedly connected to the bottom of the tooling plate 11.

[0049] The sequence valve 7 is used to control the first cylinder 12, the second cylinder 13, the fourth cylinder 8, and the third cylinder 14.

[0050] Specifically, a floating cylinder 6 is fixedly installed on one side of the top of the tooling plate 11 and is located on one side of the third oil cylinder 14. A support block is fixedly installed on the telescopic part of the floating cylinder 6.

[0051] When the floating cylinder 6 is activated, its telescopic part extends, and the support block on it can provide auxiliary support for specific parts of the product.

[0052] Specifically, two third support columns 191 and two second support columns 17 are fixedly installed on the top two sides of the tooling plate 11, respectively. The top of the two third support columns 191 is fixedly installed with the same third anti-fooling seat 19, and the top of the two second support columns 17 is fixedly installed with the same second anti-fooling seat 18. A fourth anti-fooling seat 4 is fixedly installed on one side of the top of the tooling plate 11, and two first support columns 16 are fixedly installed on the other side of the top of the tooling plate 11. The top of the two first support columns 16 is fixedly installed with the same first anti-fooling seat 15.

[0053] The product can be positioned using the first foolproof seat 15, the second foolproof seat 18, the third foolproof seat 19, and the fourth foolproof seat 4.

[0054] Specifically, positioning seats 81 are fixedly installed on both sides of the top of the tooling plate 11. The two positioning seats 81 are located on one side of the third anti-fooling seat 19 and the second anti-fooling seat 18, respectively. A receiving cavity 83 is opened in the positioning seat 81. A limiting plate 84 is slidably connected to the inner wall of the receiving cavity 83. A positioning pin 82 is fixedly installed on the top of the limiting plate 84. A spring is fixedly installed on the bottom inner wall of the receiving cavity 83. The top of the spring is fixedly connected to the bottom of the limiting plate 84.

[0055] Align the product's positioning hole with the positioning pin 82, and insert the positioning pin 82 into the product's own positioning hole to prevent incorrect product placement and perform secondary positioning.

[0056] When in use, install the tooling 1 as a whole into the required position. Before installation, observe whether the through hole of the mounting plate 25 is aligned with the mounting hole of the installation position. If not aligned, rotate the two first bolts 24. Since one end of the first bolt 24 is fixedly connected to the inner wall of the first bearing inner ring on one side of the movable plate 23, and the first bolt 24 is threadedly connected to the connecting frame 22, the position of the movable plate 23 in the movable groove can be adjusted. The movement of the movable plate 23 drives the movement of the mounting plate 25, and the mounting plate 25 can be adjusted left and right.

[0057] Rotate the second bolt 27. The rotation of the second bolt 27 causes the connecting block 28 and the mounting plate 25 to move in the direction of the groove 26. Adjust the position of the mounting plate 25 to align with the mounting hole of the installation position. Then, fix the entire device in the working position through the through holes on the mounting plate 25 and fasteners (such as bolts, screws, etc.). If the mounting mechanism 2 is not required for installation, the mounting mechanism 2 can also be removed and installed through the through holes of the tooling plate 11 itself (the tooling plate 11 has through holes at its four corners).

[0058] Connect the external air supply pipe to the other end of the first three-way pipe 53, and connect the external air supply pipe to the solenoid valve on the external machine (CNC machine). Then, the first cylinder 12, the second cylinder 13, and the fourth cylinder 8 are connected to the sequence valve 7 through the first oil passage pipe, and the third cylinder 14 is connected to the sequence valve 7 through the second oil passage pipe. The air pressure sensor 55 is controlled by an external controller, and a value within a certain range is set. The external controller is connected to the buzzer of the CNC machine.

[0059] The product to be tested is placed on the product support block 56. The first anti-misplacement seat 15, the second anti-misplacement seat 18, the third anti-misplacement seat 19 and the fourth anti-misplacement seat 4 are used to position the product. At the same time, the positioning hole of the product is aligned with the positioning pin 82, so that the positioning pin 82 is inserted into the positioning hole of the product itself to prevent the product from being placed incorrectly. The floating cylinder 6 is activated, and the telescopic part of the floating cylinder 6 extends. The support block on it can provide auxiliary support for specific parts of the product.

[0060] Start the first hydraulic cylinder 12, the second hydraulic cylinder 13, and the fourth hydraulic cylinder 8 (through the first oil passage). The telescopic parts of the cylinders extend, driving the pressure plate 31, which is hinged to them, to rotate around the hinge point. With the cooperation of the hinge frame 32 and the hinge block, the pressure plate 31 gradually presses against the product, achieving clamping and fixing of the product. Start the third hydraulic cylinder 14 (through the second oil passage). The telescopic part of the cylinder extends, driving the pressure plate 31, which is hinged to it, to rotate around the hinge point. With the cooperation of the hinge frame 32 and the hinge block, the pressure plate 31 presses against the product, and the product clamping is completed. When the product is clamped in place, the air holes 51 will be blocked on three sides of the bottom of the product.

[0061] An external air supply pipeline delivers air to the first three-way pipe 53, which then flows through the first three-way pipe 53, the second pipe, the second three-way pipe 54, the first pipe, and the two-way pipe 52 to the three product support blocks 56. Since the air holes 51 are blocked on three sides of the bottom of the product, the air pressure sensor 55 detects the air pressure changes in the pipeline. Based on the air pressure changes, it determines whether the product is properly clamped. If it is not properly clamped, a hissing sound of air leakage will be heard, and the air pressure value will be transmitted to the external controller, triggering an alarm via a buzzer. Once the product is in place, the external CNC machine will begin operation.

[0062] The entire tooling 1 is adapted to the shape of the product. The floating cylinder 6 is a support cylinder. It should be noted that the first oil cylinder 12, the second oil cylinder 13, the fourth oil cylinder 8, and the third oil cylinder 14 need to be connected to an external pump station (such as a hydraulic pump, oil tank, etc.) for use.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
