Description

Technical Field

[0001] This invention relates to the field of material performance testing technology, specifically to a smart feedback type military heavy-duty protective glove anti-slip and abrasion resistance testing device. Background Technology

[0002] The intelligent feedback type military heavy protective glove integrates functions such as high-strength protection, environmental perception and tactile feedback. The anti-slip and wear-resistant performance of its palm contact surface directly determines the operational safety of soldiers and the reliability of equipment in complex tactical environments. Therefore, it is crucial to conduct objective and accurate testing and evaluation of this performance.

[0003] Currently, traditional anti-slip and abrasion resistance testing devices mainly have the following limitations: (1) Many tests only subject the glove material sample to planar reciprocating or rotational friction, which cannot simulate the key dynamic process of the glove actively covering and holding the object with a specific gripping force in actual use, and then making relative movement. The test state is significantly different from the actual force state, resulting in a weak correlation between the test results and the actual performance. (2) In order to achieve the combined action of gripping and moving the glove sample, some existing technical solutions use multiple independent drive sources, such as motors that control the sample clamping and motors that control the sample translation, and coordinate them through a complex electronic control system. This not only makes the entire equipment structure complex and the manufacturing cost high, but also increases the system failure rate and maintenance difficulty.

[0004] Therefore, there is an urgent need in this field for an integrated testing device that can more realistically simulate actual combat grip conditions, has a compact and efficient structure, and is compatible with intelligent detection functions. To this end, we provide an intelligent feedback type military heavy-duty protective glove anti-slip and abrasion resistance testing device to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent feedback-type military heavy-duty protective glove anti-slip and abrasion resistance testing device. It can automatically complete the entire process of sample grasping of the test piece, maintaining relative frictional motion under constant pressure, and finally releasing the sample through a mechanical linkage design with a single drive source as the core. This improves the accuracy, efficiency, and economy of the test, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A smart feedback type military heavy protective glove anti-slip and abrasion resistance testing device includes a frame, a test roller rotatably mounted on the frame, a friction sensor fixedly mounted on the test roller, the test roller being clamped and fixed by a clamping assembly provided on the frame, and a movable frame slidably mounted on the frame.

A pressure sensor is embedded in the arc-shaped clamping plate. The clamping arms and the movable frame are connected by a linkage mechanism, so that when the movable frame moves linearly on the machine frame, the linkage mechanism drives the two clamping arms to rotate in opposite directions to clamp the outer wall of the test roller, and then maintains this clamping state to move horizontally with the movable frame.

The internally threaded sleeve is internally threaded and connected to a drive screw. A pin is fixed on the drive screw and the pin is clamped to the other end of the test roller.

[0008] The above-described intelligent feedback type military heavy protective glove anti-slip and abrasion resistance testing device: the frame is provided with a limiting component for the movement of the movable frame, the limiting component includes a guide rail fixed on the frame and a slider fixed at the bottom of the movable frame, the slider slidingly engaging with the guide rail.

[0009] The above-described intelligent feedback type military heavy protective glove anti-slip and wear resistance testing device includes a drive mechanism comprising a main shaft and a lead screw rotatably mounted on a frame, a drive disc fixedly mounted on the main shaft, a belt mechanism connecting the main shaft and the lead screw, the main shaft rotating to drive the lead screw to rotate, and a nut threadedly engaged with the lead screw fixed on the movable frame. A motor is fixed on the frame, and the output end of the motor is connected to the main shaft through a coupling to drive the main shaft to rotate.

[0010] The above-described intelligent feedback type military heavy protective glove anti-slip and abrasion resistance testing device includes a belt mechanism comprising an active toothed pulley fixed on a main shaft and a driven toothed pulley fixed on a lead screw, wherein the active toothed pulley and the driven toothed pulley are driven by a toothed belt.

[0011] As described above, a smart feedback type military heavy-duty protective glove anti-slip and abrasion resistance testing device includes: a linkage mechanism including a guide shaft fixed on a frame; a sliding sleeve sleeved on the guide shaft and fixed on a fixture seat; the guide shaft and the sliding sleeve are engaged by a grooved roller mechanism; the sliding sleeve is driven to rotate first and then stop rotating during the sliding process on the guide shaft; two side limiting brackets are fixed on the fixture seat; inner sliding blocks are slidably arranged inside the two side limiting brackets; the middle part of the clamping arm is hinged to the side limiting brackets; a sliding groove is opened on the inner sliding block; and a pin is fixed at the end of the clamping arm and movably engaged inside the sliding groove. The inner sliding block and the sliding sleeve are connected by a transmission mechanism. When the sliding sleeve rotates, it drives the inner sliding block to move linearly.

[0012] The above-described intelligent feedback type military heavy protective glove anti-slip and abrasion resistance testing device includes a roller embedded in the inner wall of a sliding sleeve and a guide groove opened on a guide shaft. The roller is movably engaged in the guide groove and can roll along the groove. The guide groove consists of a spiral groove and a straight groove.

[0013] The above-described intelligent feedback type military heavy-duty protective glove anti-slip and abrasion resistance testing device includes a transmission mechanism comprising a transmission shaft rotatably mounted on a fixture seat, the transmission shaft and a sliding sleeve being coupled via a worm gear mechanism, the sliding sleeve rotating to drive the transmission shaft to rotate, a drive screw sleeve rotatably mounted inside the fixture seat, the drive screw sleeve being internally threaded to a transmission screw fixed to an inner sliding block, the drive screw sleeve and the transmission shaft being coupled via a bevel gear mechanism, the transmission shaft rotating to drive the drive screw sleeve to rotate.

[0014] The above-mentioned intelligent feedback type military heavy protective glove anti-slip and wear resistance testing device: the worm gear mechanism includes a hollow worm fixed on the sliding sleeve, the hollow worm is sleeved on the guide shaft, and a worm wheel is fixed on the transmission shaft, and the hollow worm meshes with the worm wheel; The bevel gear mechanism includes a driving bevel gear fixed on the transmission shaft and a driven bevel gear fixed on the drive sleeve, wherein the driving bevel gear meshes with the driven bevel gear.

[0015] The above-described intelligent feedback type military heavy protective glove anti-slip and abrasion resistance testing device further includes a controller. The pressure sensor and friction sensor are respectively electrically connected to the controller. The pressure sensor is used to detect the clamping force of the glove sample on the test roller in real time, and the friction sensor is used to detect the friction force generated when the glove sample moves relative to the test roller in real time. The controller calculates the real-time friction coefficient of the glove sample based on the clamping force data detected by the pressure sensor and the friction force data detected by the friction sensor.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention adopts a linkage design driven by a single drive source motor. Through the main shaft and its belt mechanism, as well as the grooved roller mechanism and transmission mechanism between the movable frame and the clamping arm, the protective wear resistance test of the glove sample is completed by using one motor to synchronously control the rotation of the test roller, the linear movement of the movable frame, and the automatic clamping and loosening of the clamping arm. This completely eliminates the necessity of multiple motors and complex electrical control coordination in the traditional solution, making the overall device structure compact and the number of parts greatly reduced, thereby effectively reducing manufacturing costs, system failure rate and later maintenance difficulty, and fundamentally enhancing reliability. (2) The present invention drives the arc-shaped clamp plate with the real glove sample installed to actively grasp and cover the test roller by rotating the clamp arm, and performs horizontal relative movement while maintaining a constant clamping force. In conjunction with the rotation of the test roller itself, this process accurately simulates the real dynamic of the hand holding cylindrical objects such as gun barrels and tools and applying force in actual operation, so that the force state of the sample is highly consistent with the actual combat. Compared with the plane friction test, the test method provided by the present invention can more realistically reflect the anti-slip and wear resistance performance of glove materials in actual combat environment, and the correlation between the test results and the actual use performance is significantly enhanced. (3) This invention achieves synchronous, accurate, and in-situ measurement of the core physical quantity of the test by embedding a pressure sensor in the arc-shaped clamping plate to monitor the clamping force of the glove sample on the test roller in real time, and integrating a friction sensor on the test roller to directly measure the sliding friction force of the glove sample on the test roller. Based on these two sets of data, the controller can directly calculate the real-time static friction coefficient and dynamic friction coefficient, realize the accurate quantitative evaluation of anti-slip performance, and make the performance evaluation results of the test material more accurate.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Please see Figure 1-10 As an embodiment of the present invention, a smart feedback type military heavy protective glove anti-slip and wear resistance testing device includes a frame 1, a test roller 6 rotatably mounted on the frame 1, a friction sensor 36 fixedly mounted on the test roller 6, the test roller 6 being clamped and fixed by a clamping assembly provided on the frame 1, and a movable frame 7 slidably mounted on the frame 1. The test roller 6 and the movable frame 7 are respectively driven by a driving mechanism provided on the frame 1 to realize the rotation of the test roller 6 and the linear movement of the movable frame 7. A fixture base 17 is fixed on the movable frame 7. Two rotatable clamping arms 18 are provided on the fixture base 17. Each clamping arm 18 is fixed with an arc-shaped clamping plate 19 for mounting glove samples. A pressure sensor 35 is embedded in the arc-shaped clamping plate 19. The clamping arm 18 and the movable frame 7 are connected by a linkage mechanism, so that when the movable frame 7 moves linearly on the frame 1, the linkage mechanism drives the two clamping arms 18 to rotate in opposite directions to clamp the outer wall of the test roller 6 and then maintain this clamping state to move horizontally with the movable frame 7.

[0021] In this embodiment, during use, the movable frame 7 is first driven by the drive mechanism to move linearly on the frame 1 in the direction close to the test roller 6. During this movement, the linkage mechanism starts to work, driving the two clamping arms 18 installed on the clamping seat 17 to rotate towards each other, thereby causing the arc-shaped clamping plate 19 fixed on the clamping arm 18 and the glove sample installed on it to gradually close and finally be stably clamped on the outer wall of the test roller 6. After the clamping action is completed, the drive mechanism continues to drive the movable frame 7 to maintain linear movement. At this time, the linkage mechanism keeps the two clamping arms 18 in the clamping state and no longer rotates. Therefore, under constant clamping force, the glove sample moves horizontally relative to the surface of the rotating test roller 6 along with the movable frame 7, simulating the friction conditions when gripping gloves in actual combat. Throughout the friction test, the pressure sensor 35 embedded in the arc-shaped clamping plate 19 detects and outputs the clamping force data of the glove sample on the test roller 6 in real time. At the same time, the friction sensor 36 fixedly installed on the test roller 6 detects and outputs the friction force data generated when the two move relative to each other in real time. The external control system receives these data and can calculate and evaluate the friction coefficient of the glove sample in real time to complete the quantitative test of its anti-slip and wear-resistant performance. After the test, the drive mechanism reverses the movement of the movable frame 7, and the linkage mechanism then acts to drive the two clamping arms 18 to rotate in the opposite direction, thereby releasing the clamping state. Finally, the glove sample can be separated from the test roller 6, and the device is reset.

[0022] As a further embodiment of the present invention, the clamping assembly includes a drive disk 3 rotatably mounted on the frame 1, and a plurality of circumferentially distributed claws 15 at equal angles are fixed on the drive disk 3. One end of the test roller 6 is embedded and clamped inside the plurality of claws 15, and the other end of the test roller 6 is clamped and limited by the clamping assembly 5. The clamping assembly 5 includes an internally threaded sleeve 501 fixed on the frame 1. The internally threaded sleeve 501 is internally threaded to a drive screw 502. A push pin 503 is fixed on the drive screw 502 and is clamped to the other end of the test roller 6.

[0023] In this embodiment, the rotating drive screw 502 can drive the ejector pin 503 to move axially. The end of the test roller 6 has a hole 601, and the ejector pin 503 can be embedded in the hole 601, thereby pressing the other end of the test roller 6 tightly. At the same time, one end of the test roller 6 is radially limited by a groove formed by multiple claws 15. This structure realizes the quick clamping, accurate centering and reliable fixation of the test roller 6, and ensures that it can rotate together with the drive disk 3.

[0024] As a further embodiment of the present invention, the frame 1 is provided with a limiting component for the movement of the movable frame 7. The limiting component includes a guide rail 8 fixed on the frame 1 and a slider 9 fixed at the bottom of the movable frame 7. The slider 9 slides in cooperation with the guide rail 8.

[0025] In this embodiment, the slider 9 and the guide rail 8 form a sliding pair, which provides precise guidance for the linear movement of the movable frame 7 and effectively prevents it from deflecting or shaking during the movement, ensuring that the contact trajectory between the glove sample and the test roller 6 is stable and repeatable during the test.

[0026] As a further embodiment of the present invention, the driving mechanism includes a main shaft 2 and a lead screw 10 rotatably mounted on the frame 1, a driving disk 3 fixedly mounted on the main shaft 2, and the main shaft 2 and the lead screw 10 are connected by a belt mechanism. When the main shaft 2 rotates, it will drive the lead screw 10 to rotate. A nut 16 that is threadedly engaged with the lead screw 10 is fixed on the movable frame 7. A motor 11 is fixed on the frame 1. The output end of the motor 11 is connected to the spindle 2 through a coupling to drive the spindle 2 to rotate.

[0027] In this embodiment, the starter motor 11 can drive the main shaft 2 to rotate. The rotation of the main shaft 2 directly drives the drive disk 3 and the test roller 6 to rotate. On the other hand, it drives the lead screw 10 to rotate synchronously through the belt mechanism. The lead screw 10 and the nut 16 fixed on the movable frame 7 form a lead screw and nut pair, thereby converting the rotational motion of the lead screw 10 into the precise linear motion of the movable frame 7 along the guide rail 8. Thus, a single drive source realizes the synchronous drive of the rotation of the test roller 6 and the translation of the movable frame 7.

[0028] As a further embodiment of the present invention, the belt mechanism includes a driving toothed pulley 12 fixed on the main shaft 2 and a driven toothed pulley 13 fixed on the lead screw 10, and the driving toothed pulley 12 and the driven toothed pulley 13 are driven by a toothed belt 14.

[0029] In this embodiment, the driving toothed pulley 12, the driven toothed pulley 13, and the toothed belt 14 constitute a belt drive, which has a stable transmission ratio, can reliably transmit the power of the main shaft 2 to the lead screw 10, and allows a certain center distance between the two shafts, which is convenient for the overall layout.

[0030] As a further embodiment of the present invention, the linkage mechanism includes a guide shaft 20 fixed on the frame 1, a sliding sleeve 21 sleeved on the guide shaft 20 fixed on the clamp seat 17, the guide shaft 20 and the sliding sleeve 21 are engaged by a groove rolling mechanism, the sliding sleeve 21 is driven to rotate first during the sliding process on the guide shaft 20, and then stops rotating, two side limiting brackets 31 are fixed on the clamp seat 17, an inner sliding block 32 is slidably arranged inside the two side limiting brackets 31, the middle of the clamp arm 18 is hinged to the side limiting brackets 31, a sliding groove 33 is opened on the inner sliding block 32, and a pin 34 is fixed at the end of the clamp arm 18 and is movably engaged inside the sliding groove 33; The inner sliding block 32 and the sliding sleeve 21 are connected by a transmission mechanism. When the sliding sleeve 21 rotates, it will drive the inner sliding block 32 to move linearly.

[0031] In this embodiment, when the movable frame 7 drives the clamp seat 17 and the sliding sleeve 21 to slide along the guide shaft 20, the grooved roller mechanism forces the sliding sleeve 21 to rotate in the initial stage. The rotation of the sliding sleeve 21 drives the inner sliding block 32 to move linearly inside the side limiting bracket 31 through the transmission mechanism. The movement of the inner sliding block 32 is connected to the pin 34 at the end of the clamping arm 18 through the sliding groove 33 on it, converting the linear motion into the opposite rotation of the two clamping arms 18 around the central hinge point, thereby achieving the clamping of the test roller 6. When the sliding sleeve 21 slides to a specific section on the guide shaft 20 and stops rotating, the position of the inner sliding block 32 is locked, and the clamping angle and clamping force of the clamping arm 18 are maintained.

[0032] As a further embodiment of the present invention, the grooved roller mechanism includes a roller 23 embedded in the inner wall of the sliding sleeve 21 and a guide groove 22 formed on the guide shaft 20. The roller 23 is movably engaged in the guide groove 22 and can roll along the groove where the guide groove 22 is located. The guide groove 22 is composed of a spiral groove and a straight groove.

[0033] In this embodiment, the guide groove 22 is a track groove that combines a spiral groove and a straight groove with a specific profile. The roller 23 is constrained by the track of the guide groove 22. When the sliding sleeve 21 slides axially, it forces the roller 23 to roll along the guide groove 22, thereby precisely controlling the composite motion of the sliding sleeve 21 first rotating and then remaining stationary.

[0034] As a further embodiment of the present invention, the transmission mechanism includes a transmission shaft 24 rotatably mounted on the fixture seat 17. The transmission shaft 24 and the sliding sleeve 21 are connected by a worm gear mechanism. When the sliding sleeve 21 rotates, it drives the transmission shaft 24 to rotate. A drive screw sleeve 27 is rotatably mounted inside the fixture seat 17. The drive screw sleeve 27 is internally threaded with a transmission screw 30 fixed to the inner sliding block 32. The drive screw sleeve 27 and the transmission shaft 24 are connected by a bevel gear mechanism. When the transmission shaft 24 rotates, it drives the drive screw sleeve 27 to rotate.

[0035] In this embodiment, when the sliding sleeve 21 rotates, it drives the transmission shaft 24 to rotate through the worm gear mechanism. The rotation of the transmission shaft 24 changes the transmission direction through the bevel gear mechanism, driving the drive sleeve 27 to rotate. The drive sleeve 27 and the transmission screw 30 form a threaded pair, thereby converting the rotational motion of the drive sleeve 27 into the linear movement of the transmission screw 30 and the inner sliding block 32 fixed thereto. The worm gear mechanism has self-locking properties, which can ensure that the clamped state will not loosen in the reverse direction when there is no continuous drive.

[0036] As a further embodiment of the present invention, the worm gear mechanism includes a hollow worm 25 fixed to the sliding sleeve 21, the hollow worm 25 being sleeved on the guide shaft 20, and a worm wheel 26 fixed on the transmission shaft 24, wherein the hollow worm 25 meshes with the worm wheel 26. The bevel gear mechanism includes a driving bevel gear 28 fixed on the transmission shaft 24 and a driven bevel gear 29 fixed on the drive sleeve 27, with the driving bevel gear 28 meshing with the driven bevel gear 29.

[0037] In this embodiment, the hollow worm 25 meshes with the worm wheel 26 to form a specific worm wheel and worm gear reduction and reversing mechanism. The driving bevel gear 28 and the driven bevel gear 29 form a specific orthogonal bevel gear transmission pair, realizing the 90-degree axial transmission of power from the drive shaft 24 to the drive sleeve 27.

[0038] As a further embodiment of the present invention, it also includes a controller, and a pressure sensor 35 and a friction sensor 36 are respectively electrically connected to the controller. The pressure sensor 35 is used to detect the clamping force of the glove sample on the test roller 6 in real time, and the friction sensor 36 is used to detect the friction force generated when the glove sample moves relative to the test roller 6 in real time. The controller calculates the real-time friction coefficient of the glove sample based on the clamping force data detected by the pressure sensor 35 and the friction force data detected by the friction sensor 36.

[0039] In this embodiment, the controller constitutes the core of the device's intelligent detection and feedback. It simultaneously collects the clamping force signal from the pressure sensor 35 and the friction force signal from the friction sensor 36, and calculates and records the static and dynamic friction coefficients and their variation curves in real time through a built-in algorithm, thereby achieving an objective, quantitative, and dynamic evaluation of the anti-slip performance of the glove sample.

[0040] The working principle of this invention is as follows: The starting motor 11 rotates forward, driving the main shaft 2 to rotate. The main shaft 2, on one hand, drives the test roller 6 to rotate via the pawl 15 on the drive disc 3, and on the other hand, drives the lead screw 10 to rotate synchronously via the toothed belt 14. This, in turn, drives the movable frame 7 to move linearly along the guide rail 8 towards the test roller 6 via a threaded engagement. When the movable frame 7 moves, it drives the sliding sleeve 21 to slide along the guide shaft 20. The inner roller 23 of the sliding sleeve 21 is guided by the guide groove 22, forcing the sliding sleeve 21 to rotate in the initial stage of movement. This rotation drives the transmission shaft 24 to rotate via the hollow worm 25 and worm wheel 26, and then, through the bevel gear mechanism of the active bevel gear 28 and the arc-shaped clamping plate 19, drives the drive screw sleeve 27 to rotate. The drive screw sleeve 27 engages with the transmission screw 30 fixed on the inner sliding block 32, causing the inner sliding block 32 to move linearly. The movement of the inner sliding block 32 is achieved through its sliding groove 33 and the clamping arm 18. The engagement of the end pin 34 is converted into the opposite rotation of the two clamping arms 18, thereby clamping the glove sample mounted on the arc-shaped clamping plate 19 onto the test roller 6. When the sliding sleeve 21 slides to the straight groove section of the guide shaft 20, it stops rotating, and the clamping state of the clamping arms 18 is locked. At this time, the movable frame 7 continues to translate, and the clamped glove sample slides relative to the rotating test roller 6 surface with the movable frame 7 under constant pressure to perform friction testing. During the process, the pressure sensor 35 and the friction sensor 36 detect data in real time and transmit it to the controller, which calculates the real-time friction coefficient. After the test, the motor 11 continues to reverse, the movable frame 7 retracts, the sliding sleeve 21 slides in the opposite direction along the guide shaft 20 and reverses, and the clamping arms 18 are driven to rotate in the opposite direction to release the sample through the linkage mechanism. The device is reset, thus completing the entire process of automated clamping, testing, data acquisition and release of the glove sample.

[0041] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.
