Detailed Implementation

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1-12 As shown, the present invention specifically provides a drone pressure testing machine, including a machine platform 1 and a mounting plate 2 detachably connected to the machine platform 1;

[0036] It also includes a mounting frame 101, linear guide rails 102, electric sliders 103, a first electric push rod 104, a support plate 105, a pressure plate 106, a second electric push rod 107, a transparent blocking frame 108, a collection frame 109, and a hollow connecting frame 1010; a mounting frame 101 located in front of the mounting plate 2 is detachably connected to the machine base 1; two linear guide rails 102 are detachably connected to the mounting plate 2 and are symmetrically distributed on the left and right sides; an electric slider 103 is slidably connected to each linear guide rail 102; all electric... The movable slider 103 is detachably connected to another mounting frame 101 located in front of the mounting plate 2, and the two mounting frames 101 are arranged vertically opposite each other; the mounting frame 101 on the electric slider 103 is detachably connected to two first electric push rods 104 that are symmetrically distributed from left to right and have their telescopic ends facing downwards, and the first electric push rods 104 are equipped with pressure sensors; the mounting frame 101 on the machine base 1 is connected to a support plate 105; the telescopic ends of all the first electric push rods 104 are detachably connected to a pressure plate 106; the support plate Both support plate 105 and pressure plate 106 are located between two mounting frames 101. The length and width of support plate 105 are smaller than those of pressure plate 106. The mounting frame 101 on the machine base 1 is detachably connected to two second electric push rods 107 that are symmetrically distributed on the left and right and have their telescopic ends facing upwards. The telescopic ends of all the second electric push rods 107 are connected to a transparent blocking frame 108. The transparent blocking frame 108 can be made of acrylic or glass. The length and width of the internal space of the transparent blocking frame 108 are the same as those of pressure plate 106. A collection frame 109 is detachably connected to the support plate 105. The collection frame 109 has a collection cavity 10901. The length and width of the collection frame 109 are the same as those of the pressure plate 106. Two hollow connecting frames 1010 are detachably connected to the transparent blocking frame 108. The hollow connecting frames 1010 are detachably connected to the telescopic end of the second electric push rod 107. An exhaust port 10801 communicating with the hollow connecting frame 1010 is opened in the area of ​​the transparent blocking frame 108 located within the hollow connecting frame 1010.

[0037] like Figure 5 and Figure 6 As shown, to prevent debris from splashing during the pressure test from entering the hollow connecting frame 1010 through the exhaust port 10801, each exhaust port 10801 of the transparent barrier frame 108 is detachably connected with a filter screen 201.

[0038] like Figure 4 , Figure 5 and Figure 6 As shown, in order to facilitate the discharge of debris falling onto the vent 10801 into the collection frame 109, the lower part of the vent 10801 is designed to be inclined toward the collection frame 109.

[0039] like Figure 4 , Figure 5 and Figure 6 As shown, in order to facilitate control of the upward movement distance of the transparent blocking frame 108, a limiting part 10802 is provided at the lower part of the transparent blocking frame 108.

[0040] Before testing, samples are prepared according to the manufacturing processes of components such as the drone shell, wings, and connecting rods. Then, the operator places the sample centered on the support plate 105, controls the second electric push rod 107 to push the transparent blocking frame 108 upwards, and simultaneously controls the electric slider 103 to move its connected mounting frame 101 and other components downwards until... Figure 11 As shown, the limiting part 10802 on the transparent barrier frame 108 contacts the collection frame 109, the four sides of the pressure plate 106 contact the four walls inside the transparent barrier frame 108, and the four outer sides of the collection frame 109 contact the four walls inside the transparent barrier frame 108, so that the sample is located in the sealed space formed by the support plate 105, the pressure plate 106, the transparent barrier frame 108, and the collection frame 109, preventing flying debris from contaminating the ground and causing injury to the operator during subsequent testing; then, the first electric push rod 104 is controlled to drive the pressure plate 106 downward, so that the pressure plate 106 applies a squeezing force to the sample placed on the support plate 105 until the sample is destroyed; during the test, the pressure sensor set on the first electric push rod 104 monitors the pressure value. After the sample is destroyed, the first electric push rod 104 is controlled to drive the pressure plate 106 upward to reset, and the maximum pressure value is taken as the maximum pressure resistance data of the sample; during the test, some flying debris is subjected to the transparent barrier frame 105. After being blocked by the 08, the sample falls into the collection chamber 10901 of the collection frame 109 and is collected. Some of the sample bounces back onto the support plate 105. During the test, the operator observes the sample's condition through the transparent blocking frame 108 and evaluates the sample's compressive strength. Alternatively, a camera can be installed on the mounting plate 2 to observe the sample's condition during the test instead of the operator. After the compressive strength test is completed, the second electric push rod 107 is controlled to reset the transparent blocking frame 108, and the electric slider 103 is simultaneously controlled to reset the connected mounting frame 101 and other components. Then, the operator sweeps the tested sample and fallen debris from the support plate 105 into the collection chamber 10901. With the collection frame 109, there is no need to use a handheld collection tool to collect the swept sample and debris, making it easier for the operator to quickly process the sample and debris on the support plate 105 and facilitate rapid testing of subsequent samples. Note that multiple data sets are required to ensure the accuracy of the test data.

[0041] Note that when the sample is placed in the sealed space composed of the support plate 105, the pressure plate 106, the transparent barrier frame 108, and the collection frame 109, and the first electric push rod 104 drives the pressure plate 106 to move downward to test the sample, the gas in the sealed space is discharged through the exhaust port 10801 and the hollow connecting frame 1010 to avoid the formation of a high-pressure environment in the sealed space, which would hinder the downward movement of the pressure plate 106 and affect the accuracy of the pressure sensor in monitoring the pressure.

[0042] Note that when the device is idle or after all samples to be tested have been tested, the operator should remove the collection box 109 from the support plate 105, empty and clean the debris and samples collected in the collection box 109, and then reinstall the collection box 109 onto the support plate 105.

[0043] like Figure 4 , Figure 5 , Figure 11 and Figure 12 As shown, it also includes a third electric push rod 301, a fourth electric push rod 302, a servo motor 303, a two-finger electric gripper 304, and a semi-circular block 305; the mounting frame 101 on the machine base 1 is detachably connected to two third electric push rods 301 that are symmetrically distributed on the left and right sides with their telescopic ends facing upwards, and the telescopic ends of all third electric push rods 301 are detachably connected to the support plate 105; the mounting frame 101 on the machine base 1 is detachably connected to three fourth electric push rods 302 that are distributed in a linear array with their telescopic ends facing downwards, and the fourth electric push rods 302 are equipped with tension sensors; the first electric push rod 104 and the fourth electric push rod 302 are staggered on the mounting frame 101; the mounting frame 101 on the electric slider 103 can... The system includes three servo motors 303 arranged in a linear array with their output ends facing upwards. Each servo motor 303 is equipped with a torque sensor. The third electric push rod 301 and the servo motors 303 are staggered on the mounting frame 101. Each fourth electric push rod 302 and each servo motor 303 can be detachably connected to a two-finger electric gripper 304 at their telescopic end. Each two-finger electric gripper 304 has a semi-circular block 305 detachably connected to its gripper drive part 30401. Two semi-circular blocks 305 on the same two-finger electric gripper 304 form a complete circular block. Both the support plate 105 and the pressure plate 106 have three circular through holes arranged in a linear array with a diameter equal to that of the semi-circular blocks 305.

[0044] like Figure 6As shown, in order to improve the cleaning effect of the test samples and debris on the support plate 105, each exhaust port 10801 of the transparent barrier frame 108 is provided with several partitions 10803. The partitions 10803 divide the exhaust port 10801 into several independent exhaust channels. With the midpoint of the exhaust port 10801 as the reference point, the exhaust channel in front of the reference point is tilted to face forward, and the exhaust channel behind the reference point is tilted to face backward.

[0045] Before the sample is subjected to a compressive strength test, the two gripper drive parts 30401 of the two-finger electric gripper 304 are in a closed state. The two semicircular blocks 305 on the two-finger electric gripper 304 are combined to form a complete circular block, and the semicircular blocks 305 are located in the circular through holes on the support plate 105 and the pressure plate 106, filling and smoothing the side of the support plate 105 and the pressure plate 106 used for sample compressive strength testing, ensuring stable performance of the compressive strength test. During the sample compressive strength test, as the first electric push rod 104 moves the pressure plate 106, the fourth electric push rod 302 drives the two-finger electric gripper 304 to move synchronously with the pressure plate 106, so that the semicircular blocks 305 always fill and smooth the side of the pressure plate 106 used for sample compressive strength testing.

[0046] Furthermore, before conducting the pressure resistance test, airbags are pre-attached to both hollow connecting frames 1010. During the test, the first electric push rod 104 moves the pressure plate 106 downward, allowing the gas in the sealed space to be discharged through the exhaust port 10801 and the hollow connecting frame 1010, and then enters the external airbags, causing them to inflate. During the pressure resistance test, if the sample is damaged and the first electric push rod 104 moves the pressure plate 106 upward to reset, the fourth electric push rod 302 is first controlled to stop operating. After the sealed space is connected to the outside through the circular through hole on the pressure plate 106, the fourth electric push rod 302 is then controlled to drive the two-finger electric clamp. The claw 304 moves upward, but the semi-circular block 305 on the two-finger electric gripper 304 must always be below the pressure plate 106 to avoid blocking the circular through hole on the pressure plate 106. At this time, the expanded external airbag will contract, and the gas that enters the external airbag will quickly pass through the hollow connecting frame 1010 and the exhaust port 10801 into the transparent blocking frame 108, blowing the tested sample and debris on the support plate 105 into the collection frame 109 for collection, realizing the automatic cleaning operation after the pressure test, improving the efficiency of the operator in cleaning debris before subsequent sample testing; and the automatic cleaning operation after the pressure test is based on the gas discharged in the closed space, which is ingenious.

[0047] Note that during the pressure test, after the limiting part 10802 on the transparent barrier frame 108 comes into contact with the collection frame 109, the exhaust port 10801 faces the upper surface of the support plate 105 to ensure the automatic cleaning effect after the pressure test is completed.

[0048] Furthermore, such as Figure 6 As shown, the exhaust port 10801 is divided into several independent exhaust channels by the partition 10803. With the midpoint of the exhaust port 10801 as the reference point, the exhaust channel in front of the reference point is tilted forward, and the exhaust channel behind the reference point is tilted backward. When the gas in the external airbag is discharged into the transparent baffle frame 108 through the exhaust port 10801, the gas flows in a figure-eight shape, which improves the cleaning effect of the gas on the test sample and debris on the support plate 105.

[0049] Furthermore, in addition to performing compressive strength testing on samples, this invention can also perform tensile strength testing on samples. Specifically, when tensile strength testing of samples is required using this invention, the fourth electric push rod 302 is controlled to drive the two-finger electric gripper 304 to move downwards, and simultaneously the third electric push rod 301 drives the support plate 105 to move downwards. Figure 12 As shown, the gripper drive unit 30401 and semicircular block 305 of the upper two-finger electric gripper 304 are positioned below the pressure plate 106, and the gripper drive unit 30401 and semicircular block 305 of the lower two-finger electric gripper 304 are positioned above the support plate 105; then, the electric slider 103 is controlled to drive the connected mounting frame 101 and other components to move downwards, so that the distance between the upper and lower opposing semicircular blocks 305 is less than 5cm of the length of the sample to be tested for tensile strength. Then, the two-finger electric gripper 304 is controlled to move, so that the two semicircular blocks 305 on the two-finger electric gripper 304 move away from each other. Then, the operator places the upper and lower ends of the sample to be tested on the upper and lower opposing two-finger electric grippers 304 in sequence, and controls the upper and lower opposing two-finger electric grippers 304 in sequence to move, so that the two semicircular blocks 305 on the two-finger electric grippers 304 move closer to each other to fix the sample; then the second... The electric push rod 107 pushes the transparent blocking frame 108 upward until the limiting part 10802 on the transparent blocking frame 108 contacts the lower side of the collection frame 109, blocking the debris that splashes during the tensile testing of the subsequent sample. Then, the electric slider 103 is controlled to move the connected mounting frame 101 and other components upward to perform tensile testing on the sample. Note that during the testing process, the first electric push rod 104 moves the pressure plate 106 downward, keeping the pressure plate 106 stationary relative to the transparent blocking frame 108. During the testing process, the tensile force value is monitored by the tensile force sensor set on the fourth electric push rod 302. After the sample breaks, the maximum tensile force value is taken as the maximum tensile strength data of the sample. In summary, this invention can perform tensile testing on the sample in addition to compressive strength testing, which improves the versatility and practicality of compressive strength testing machines compared to existing compressive strength testing machines.

[0050] After the tensile test is completed, if another tensile test is required, first control the two-finger electric gripper 304 to open, causing the sample fixed on the semicircular block 305 to fall off. Then, control the electric slider 103 again to move the connected mounting frame 101 and other components downwards, allowing the operator to install the sample to be tested. If no tensile test is required, similarly, first control the two-finger electric gripper 304 to open, causing the sample fixed on the semicircular block 305 to fall off. Then, control the two-finger electric gripper 304 to move the semicircular block 305 downwards. 05 Reset, so that the two semicircular blocks 305 on the two-finger electric gripper 304 re-form a complete circular block. Then control the fourth electric push rod 302 to drive the two-finger electric gripper 304 to reset. The third electric push rod 301 drives the support plate 105 to reset, filling and flattening the side of the support plate 105 and the pressure plate 106 used for sample compression testing. Then control the second electric push rod 107 to drive the transparent blocking frame 108 to reset. Control the electric slider 103 to drive the connected mounting frame 101 and other components to reset.

[0051] Furthermore, in addition to tensile testing of the sample, the two-finger electric gripper 304 can be rotated by the servo motor 303 to apply torsional force to the sample for torsion testing, thereby further enhancing the versatility of the compressive strength testing machine of the present invention. During the torsion testing process, the torque value is monitored by the torque sensor set on the servo motor 303. After the sample breaks, the maximum torque value is taken as the maximum torsion resistance data of the sample.

[0052] like Figure 4 , Figure 5 and Figure 7 As shown, it also includes a guide plate 401; the collection frame 109 is detachably connected to a guide plate 401 with an inverted V-shaped upper surface; the collection frame 109 has two discharge ports 10902 that are symmetrically distributed front and back and communicate with the collection cavity 10901; the lowest point of the discharge port 10902 is on the same horizontal line as the lowest point of the upper surface of the guide plate 401; the guide plate 401 has three first clearance grooves 40101 that are arranged in a linear array and have the same shape as the electric gripper 304; the main body of the two-finger electric gripper 304 is located in the first clearance groove 40101; the guide plate 401 has two second clearance grooves 40102 that are symmetrically distributed left and right and have the same diameter as the telescopic end of the third electric push rod 301; the telescopic end of the third electric push rod 301 is located in the second clearance groove 40102.

[0053] like Figure 8 As shown, it also includes a blocking block 501; the two semicircular blocks 305 on each two-finger electric gripper 304 are slidably connected to the blocking block 501; the upper surface of the blocking block 501 located below is set in an inverted V shape.

[0054] When performing tensile or torsional tests on samples, it should be considered that, Figure 12 As shown, the circular through-hole on the support plate 105 is no longer filled by the semicircular block 305, and the two semicircular blocks 305 on the two-finger electric gripper 304 open, causing debris generated during tensile or torsional testing to fall through the circular through-hole on the support plate 105 onto the mounting frame 101 and the components connected to the mounting frame 101. To address this, a guide plate 401 with an inverted V-shaped upper surface is provided on the collection frame 109, and a discharge port 10902 communicating with the collection cavity 10901 is opened on the collection frame 109. This allows debris passing through the circular through-hole during tensile or torsional testing to fall onto the guide plate 401, and then slide along the guide plate 401 toward the discharge port 10902 until the debris enters the collection cavity 10901 of the collection frame 109 through the discharge port 10902 for collection, thus preventing debris from falling through the circular through-hole onto the mounting frame 101 and the components connected to the mounting frame 101.

[0055] Note that when performing tensile or torsional tests on the sample, the third electric push rod 301 moves the support plate 105 downward, so that the gripper drive part 30401 and the semi-circular block 305 of the lower two-finger electric gripper 304 are above the support plate 105. After that, the first clearance groove 40101 is completely fitted with the body of the two-finger electric gripper 304, and the second clearance groove 40102 is fitted with the telescopic end of the third electric push rod 301, so as to prevent debris from falling into the mounting frame 101 and the components connected to the mounting frame 101 through the first clearance groove 40101 and the second clearance groove 40102.

[0056] Furthermore, to prevent debris from falling into the main body of the lower two-finger electric gripper 304 and affecting its operation, a blocking block 501 is provided between the two semicircular blocks 305 on the two-finger electric gripper 304. When the two semicircular blocks 305 are opened during tensile or torsional testing of the sample, the blocking block 501 is exposed, thus shielding the main body of the two-finger electric gripper 304 and preventing debris generated during tensile or torsional testing from falling into its main body. The upper surface of the shielding block 501 is designed as an inverted V-shape, so that debris falling onto it can be guided to the guide plate 401 and then discharged into the collection chamber 10901 for collection. At the same time, when the tensile test or torsional test is completed, the two-finger electric gripper 304 is controlled to open, allowing the sample fixed on the semicircular block 305 to fall off. The detached sample can be guided to the guide plate 401 through the shielding block 501 and then discharged into the collection chamber 10901 for collection. Note that when the sample is fixed on the semicircular block 305, the sample is in contact with the shielding block 501. The shielding block 501 limits the sample and improves the installation speed before sample testing.

[0057] like Figure 9 and Figure 10 As shown, it also includes a connecting plate 601, a connecting block 602, a connecting strip 603, and a rubber post 604; each hollow connecting frame 1010 can be detachably connected to a connecting plate 601; each connecting plate 601 has several openings 60101 arranged in a linear array; each opening 60101 can be detachably connected to a connecting block 602; each connecting block 602 can be detachably connected to a connecting strip 603 on the side facing the transparent blocking frame 108; each connecting strip 603 can be detachably connected to a rubber post 604 at the end away from the connecting block 602.

[0058] like Figure 10 As shown, in order to reduce the obstruction of gas, the thickness of each connecting block 602 on the side away from the transparent barrier frame 108 is smaller than that on the side of the connecting block 602 facing the transparent barrier frame 108.

[0059] During the process of the inflated external airbag contracting, the gas inside the external airbag is discharged into the transparent barrier frame 108 through the hollow connecting frame 1010 and the exhaust port 10801, blowing the tested samples and debris on the support plate 105 into the collection frame 109 for collection. During this process, the gas inside the external airbag must first pass through the opening 60101 on the connecting plate 601. When the gas passes through the opening 60101, the gas will blow the connecting belt 603, causing the connecting belt 603 to drive the rubber column 604 to knock the filter screen 201, shaking off the debris stuck on the filter screen 201, avoiding clogging of the filter screen 201, which would affect the gas passage and the cleaning effect on the tested samples and debris on the support plate 105.

The scope of the following claims should be given the broadest interpretation so as to cover all variations and equivalent structures and functions.
