[0023] Currently, a dexterous hand is an automated operating device that can mimic certain movements and functions of a human hand to grasp, move objects, or operate tools according to a fixed program. To ensure the quality of a dexterous hand, functional testing fixtures are needed to test its various functional parameters. Commonly used functional testing fixtures typically have different types of testing stations to perform different functional parameter tests. After each type of functional test is completed, the dexterous hand must be disassembled and reassembled, resulting in lengthy testing times and low testing efficiency.

[0024] Based on this, the following embodiments of this application propose a dexterity hand testing fixture. By installing a first sliding component and a dexterity hand mounting base that can slide on the first sliding component, and installing testing modules such as the left thumb repetitive motion accuracy testing module, the four-finger initial zero position testing module, the four-finger repetitive motion accuracy testing module, the finger length testing module, the four-finger grip strength testing module, and the thumb fingertip strength testing module on the same side of the first sliding component, the dexterity hand can be detachably mounted on the dexterity hand mounting base during different types of functional tests. After each type of functional test is completed, the dexterity hand mounting base is slid along the first sliding component to the position of the next testing module to be tested. This avoids the need to disassemble and reassemble the dexterity hand after each type of functional test, saving time during the testing process, shortening the functional testing time, and improving the testing efficiency of the dexterity hand.

[0036] Furthermore, the first movable plate 301 is equipped with a screw plunger to limit the dexterity hand mounting base 3, so that the dexterity hand mounting base can be fixed at different test modules.

[0037] See Figure 4 The diagram shows the structure of the left thumb repetitive motion accuracy test module and the four-finger initial zero position test module. The left thumb repetitive motion accuracy test module 4 includes: multiple first columns 401, a first mounting plate 402, a second sliding component 403, a first dial indicator mounting block 404, a first moving block 405, and a first dial indicator 406.

[0039] The first dial indicator mounting block 404 and the four-finger initial zero position test module 5 are respectively mounted on the first mounting plate 402.

[0040] The first moving block 405 is fixedly connected to the second sliding component 403, and the first moving block 405 slides within the second sliding component 403 along the extending direction of the second sliding component 403.

[0055] The second movable plate 504 is provided with the four-finger contact portion 505 at one end facing the first sliding component 2.

[0056] The four-finger contact portion 505 is used to withstand the pressure of the four fingers of a dexterous hand.

[0057] See Figure 7 The diagram shows the structure of the first mounting platform, the four-finger repetitive motion accuracy testing module, and the finger length testing module. The first mounting platform 6 includes: a third column 601 and a third mounting plate 602.

[0058] The third column 601 is fixedly installed on the base plate 1, and the third mounting plate 602 is fixed on the third column 601. The third mounting plate 602 is provided with the four-finger repetitive motion accuracy test module 7 and the finger length test module 8.

[0059] like Figure 7 As shown, the four-finger repetitive motion accuracy test module 7 includes: a fourth sliding component 701, a second dial indicator mounting block 702, a second moving block 703, and a second dial indicator 704.

[0060] The fourth sliding component 701 and the second dial indicator mounting block 702 are respectively fixed on the third mounting plate 602, and the extension direction of the fourth sliding component 701 is perpendicular to the extension direction of the first sliding component 2.

[0061] The second moving block 703 has an "L" shaped structure.

[0062] The second moving block 703 is fixedly connected to the fourth sliding component 701, and the second moving block 703 can slide along the extension direction of the fourth sliding component 701.

[0063] The second dial indicator 704 is fixed on the second dial indicator mounting block 702.

[0064] The measuring needle of the second dial indicator 704 is oriented toward the second moving block 703.

[0065] The end of the second moving block 703 that is away from the second dial indicator 704 is used to withstand the pressure of the four fingers of a dexterous hand.

[0066] like Figure 7As shown, the finger length testing module 8 includes: a third dial indicator mounting base 801, a screw-down plunger mounting block 802, a third dial indicator 803, and a finger pressure plate 804.

[0067] The third dial indicator mounting base 801 includes a fixing part 8011 and an extension part 8012; the top of the fixing part 8011 is connected to one end of the extension part 8012, and the bottom of the fixing part 8011 is fixed on the third mounting plate 602; the fixed third dial indicator mounting base 801 is located next to the four-finger repetitive motion accuracy test module 7.

[0068] The other end of the extension 8012 is close to the first sliding component 2.

[0069] The screw-on plunger mounting block 802 is disposed on the bottom surface of the extension 8012.

[0070] The third dial indicator 803 is fixedly installed on the extension 8012.

[0071] The test probe of the third micrometer 803 passes through the extension 8012 and the screw-on plunger mounting block 802 and is connected to the finger pressure plate 804.

[0072] A screw-in plunger is provided on the screw-in plunger mounting block 802.

[0073] Among them, the finger pressure plate 804 is used to contact the thumb or four fingers of a dexterous hand.

[0074] When changing the position of the probe extension of the third dial indicator 803, turning the plunger is used to limit and fix it.

[0075] like Figure 7 As shown, two finger length testing modules 8 can be set on the first mounting platform 6. The difference between the two finger length testing modules 8 is that the size of the third dial indicator mounting base 801 is different, so that they can be used to measure the length of the thumb and the length of the four fingers of a dexterous hand, respectively.

[0076] like Figure 1 As shown, the dexterous hand testing fixture proposed in this embodiment also includes: a second mounting platform 12, a sensor display 13, and a junction box 14.

[0077] The four-finger grip strength testing module 9 includes: a support column 901, a first sensor 902, and a rubber ball 903.

[0078] The bottom of the support column 901 is fixed to the base plate 1, and the top of the support column 901 is fixed with the first sensor 902. A rubber ball 903 is provided on the top of the first sensor 902.

[0080] The junction box 14 is fixed on the base plate 1, and the fixed junction box 14 is located at the bottom of the second mounting platform 12.

[0081] The sensor display 13 is fixed to the top of the second mounting platform 12.

[0082] The first sensor 902 is connected to the junction box 14.

[0083] Among them, the design of the rubber ball 903 is more suitable for the joints of bent fingers, thus obtaining the bending force of each of the four fingers.

[0084] The sensor display 13 is used to display the magnitude of the pressure applied to the first sensor 902 and the second sensor 1005.

[0085] See Figure 8 The schematic diagram of the thumb fingertip force testing module shown is provided. The thumb fingertip force testing module 10 includes: a fourth column 1001, a fourth mounting plate 1002, a fifth sliding component 1003, a third moving plate 1004, two second sensors 1005, and a thumb side pressure plate 1006.

[0086] The fourth column 1001 is fixed on the base plate 1, and the fourth mounting plate 1002 is fixed on the fourth column 1001.

[0087] The fifth sliding component 1003 is disposed on the fourth mounting plate 1002, wherein the extending direction of the fifth sliding component 1003 is perpendicular to the extending direction of the first sliding component 2.

[0088] The third movable plate 1004 is fixedly connected to the fifth sliding component 1003, and the third movable plate 1004 can slide along the extension direction of the fifth sliding component 1003.

[0089] The third moving plate 1004 has two second sensors 1005 symmetrically arranged on one side facing the first sliding component 2.

[0090] Each of the two second sensors 1005 is provided with the thumb side pressure plate 1006.

[0091] Each of the second sensors 1005 is connected to the junction box 14.

[0092] The thumb side pressure plate 1006 is used to withstand the pressure of the thumb of a dexterous hand.

[0093] In this embodiment, the first sliding component 2, the second sliding component 403, the third sliding component 503, the fourth sliding component 701, and the fifth sliding component 1003 are all structures in which a guide rail and a slider cooperate. The slider can slide within the guide rail.

[0094] The specific meaning of the fixed connection between the dexterous hand mounting base 3 and the first sliding component 2 is that the dexterous hand mounting base 3 is fixed on the slider of the first sliding component 2 through the first moving plate 301, and slides along the guide rail set by the first sliding component 2 as the slider of the first sliding component 2 slides.

[0095] The specific meaning of the fixed connection between the first movable plate 301 and the first sliding component 2 is that the first movable plate 301 is fixed on the slider of the first sliding component 2, and slides along the guide rail set by the slider of the first sliding component 2.

[0096] The specific meanings of the fixed connection between the first moving block 405 and the second sliding component 403, the fixed connection between the second moving plate 504 and the third sliding component 503, the fixed connection between the second moving block 703 and the fourth sliding component 701, and the fixed connection between the third moving plate 1004 and the fifth sliding component 1003 are all similar to the above-mentioned "specific meanings of the fixed connection between the first moving plate 301 and the first sliding component 2", and will not be repeated here.

[0097] The first sliding component 2 has limit screws 16 at both ends of its guide rail. Since the limit screws 16 are covered with rubber, they provide some protection when the dexterous hand mounting base 3 collides with the limit screws 16. The second sliding component 403 has a limit block at the end of its guide rail away from the first dial indicator mounting block 404. The fourth sliding component 701 has a limit block at the end of its guide rail away from the second dial indicator mounting block 702. The fifth sliding component 1003 has limit blocks at both ends of its guide rail. The limit blocks are detachably connected. Both the limit screws 16 and the limit blocks serve to limit the movement and prevent the slider of the sliding component from detaching from the guide rail.

[0098] The first movable plate 301, which is fixedly connected to the slider of the first sliding component 2, the first movable block 405, which is fixedly connected to the second sliding component 403, the second movable plate 504, which is fixedly connected to the third sliding component 503, the second movable block 703, which is fixedly connected to the fourth sliding component 701, and the third movable plate 1004, which is fixedly connected to the fifth sliding component 1003, are respectively provided with a screw plunger. The guide rail or mounting plate of the corresponding sliding component is provided with multiple limiting holes. The cooperation between the screw plunger and the limiting hole can change or fix the position of the first movable plate 301, the first "L" shaped movable block 405, the second movable plate 504, the second "L" shaped movable block 703, and the third movable plate 1004. It can also facilitate the movement of the dexterous hand mounting base 3, which is equipped with a dexterous hand, without obstruction.

[0099] The working process of the dexterity hand testing fixture proposed in this embodiment is as follows: First, the dexterity hand to be tested is installed on the dexterity hand mounting base 3. According to the functional parameter results to be obtained, the position of the dexterity hand mounting base 3 is changed so that the dexterity hand slides through the dexterity hand mounting base 3 to the corresponding testing position. The dexterity hand mounting base 3 is temporarily fixed by the action of turning the plunger and the positioning hole 102.

[0100] When it is necessary to determine the repeatability accuracy of the thumb of the dexterous hand, slide the dexterous hand mounting base 3, on which the dexterous hand is mounted, to the left thumb repeatability accuracy test module 4 or the right thumb repeatability accuracy test module 10, manually change the position of the support pin 4053 so that the thumb of the dexterous hand contacts the support pin 4053, which drives the first moving block 405 to contact the measuring needle of the first dial indicator 406, thereby obtaining the repeatability accuracy of the thumb of the dexterous hand based on the reading of the first dial indicator 406.

[0101] When it is necessary to determine the initial zero position of the four fingers of the dexterous hand, slide the dexterous hand mounting base 3 with the dexterous hand installed to the four-finger initial zero position test module 5, and control the four-finger contact part 505 to move to the four fingers of the dexterous hand, thereby obtaining the flatness of the four fingers.

[0102] When it is necessary to determine the repetitive motion accuracy of the four fingers of the dexterous hand, the dexterous hand mounting base 3 with the dexterous hand installed is slid to the four-finger repetitive motion accuracy test module 7, and the four fingers of the dexterous hand are controlled to contact the large end of the second moving block 703, which drives the second moving block 703 to contact the measuring needle of the second dial indicator 704, so as to obtain the repetitive motion accuracy of the four fingers of the dexterous hand based on the reading of the second dial indicator 704.

[0103] When it is necessary to determine the length of each finger of the dexterous hand, the dexterous hand mounting base 3 with the dexterous hand installed is slid to the finger length testing module 8, and the movement of the measuring needle of the third dial indicator 803 is controlled so that the finger pressure plate 804 contacts the tip of the finger of the dexterous hand. The length of each finger of the dexterous hand can be indirectly obtained based on the readings of the third dial indicator 803.

[0104] When it is necessary to determine the gripping force of the four fingers of the dexterous hand, slide the dexterous hand mounting base 3 with the dexterous hand installed to the four-finger gripping force testing module 9, and control the four fingers of the dexterous hand to bend and grasp the rubber ball 903. The first sensor 902 will obtain the gripping force of the four fingers and display it on the sensor display 13.

[0105] When it is necessary to determine the fingertip force of the dexterous hand's thumb, the dexterous hand mounting base 3 with the dexterous hand installed is moved to the thumb fingertip force testing module 10. The left and right hands of the dexterous hand are distinguished, and the thumb fingertip is controlled to press the thumb side pressure plate 1006 respectively. The second sensor 1005 will obtain the thumb pressing force of the dexterous hand and display the obtained thumb pressing force of the dexterous hand on the sensor display 13.

[0106] In summary, this embodiment proposes a dexterity hand testing fixture. By installing a first sliding component and a dexterity hand mounting base that slides on the first sliding component, and mounting the following testing modules for dexterity hand testing—including the left thumb repetitive motion accuracy testing module, the four-finger initial zero-position testing module, the four-finger repetitive motion accuracy testing module, the finger length testing module, the four-finger grip strength testing module, and the thumb fingertip strength testing module—on the same side of the first sliding component, this approach differs from related technologies where the dexterity hand needs to be disassembled and reassembled after each type of functional test. In this method, the dexterity hand is mounted on the mounting base, and after each type of functional test, the mounting base slides with the first sliding component to the next testing module for functional testing. This avoids the need for disassembly and reassembly after each type of functional test, saving time and shortening the testing time, thus improving the testing efficiency of the dexterity hand.

[0107] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
