[0058] like Figures 1 to 4 As shown, an embodiment of the present invention provides a protective glove wear resistance tester, comprising a frame, wherein the frame comprises a test bench 100 and a column 200 mounted on the test bench 100;

[0059] A first guide portion 500 is disposed in the column 200 and moves up and down relative to the column 200;

[0060] The hand model device 400 is connected to the first guide part 500 and can move synchronously with the first guide part 500;

[0061] A second guide portion 800;

[0062] A grinding rod testing device 700 is connected to the second guide portion 800 and can move horizontally along the second guide portion 800;

[0063] The grab test device 600 is detachably connected to the test bench 100 and has a plurality of wear-resistant test pieces built therein for testing the wear resistance of the test sample;

[0064] Wherein, the hand model device 400 comprises:

[0065] A hand model assembly 410, wherein the hand model assembly 410 includes a hand model 411 with movable fingers and used for wearing the sample to be tested;

[0066] A hand model driving device 420 is installed on the first guide portion 500 and connected to the hand model assembly 410, and is used to drive the hand model assembly 410 to reciprocate up and down and insert into the wear-resistant test piece;

[0067] The grinding rod testing device 700 comprises:

[0068] The grinding rod assembly 710 includes a grinding rod 711 and a rotation loading part for controlling the rotation of the grinding rod 711;

[0069] A grinding rod driving device 720, connected to the grinding rod assembly 710, for driving the grinding rod 711 to perform a reciprocating pulling action in the hand mold 411;

[0070] In this embodiment, four support legs 300 are threadedly connected to the test bench 100, and threaded columns are provided on the four support legs 300. Threaded holes are provided at corresponding positions of the test bench 100, and the height of the support legs 300 is adjustable. In addition, vibration isolation pads are installed at the bottom of the support legs 300 to reduce the influence of vibration generated by the operation of the equipment during the detection process on the detection results.

[0071] The column 200 is fixed to the test bench 100 by bolt connection. In this specific embodiment, the column 200 includes two parallel arranged, plate-shaped, high-precision metal columns 200, which are arranged in parallel on one side of the test bench 100, and also includes a first connecting member 210 installed on the top of the column 200, and the first connecting member 210 can be a rectangular plate-shaped structure. Of course, the structure of the column 200 is not limited to this, and can also be replaced by a similar solution without affecting the purpose of the present invention.

[0072] In this specific embodiment, the first guide part 500 specifically includes a connecting flange 510, two parallel high-precision guide rods 520, the upper ends of the guide rods 520 are connected to the first connecting member 210, and the lower ends of the guide rods 520 are connected to the test bench 100, and also includes a linear bearing 530 with clearance fit with the guide rods 520, the linear bearing 530 is fixedly connected to the rear end of the connecting flange 510, and the front end of the connecting flange 510 is connected to the hand model assembly 410. Of course, the structure of the first guide part 500 is not limited to this, and can also be replaced by a similar solution without affecting the purpose of the present invention.

[0073] The first guide part 500 also includes a lifting and loading part 540, which can be a cylinder. The top of the cylinder, i.e., the telescopic arm of the cylinder, is connected to the hand model driving device 420 by bolts, and the bottom of the cylinder is connected to the test bench 100 by bolts.

[0074] In the non-testing state, the telescopic arm of the cylinder extends outward, and the cylinder drives the first guide part 500 and the hand model device 400 to rise together, so that the sample to be tested is away from the sample to be tested on the test bench 100. When testing is required, the telescopic arm of the cylinder shrinks, and the lifting and loading part 540 drives the first guide part 500 and the hand model assembly 410 to descend together, so that the sample to be tested is close to the grasping test device 600 or the grinding rod test device 700 on the test bench 100, and reaches the position to be tested. Of course, the structure and installation method of the lifting and loading part 540 can be replaced by other solutions, and are not limited to this.

[0075] A hand model assembly 410 is installed at the front end of the connecting flange 510, and the hand model assembly 410 includes a supporting device 413 connected to the connecting flange 510, a hand model 411 with flexible fingers, and a hand model fixing block 412 arranged between the supporting device 413 and the hand model 411, and the hand model fixing block 412 serves as a detachable installation of the hand model 411. A servo motor and a force sensor for driving the fingers of the manipulator are installed inside the hand model 411, and the hand model 411 is wrapped with a plastic shell. Specifically, the manipulator of the flexible hand model 411 can be a multi-section connecting rod structure.

[0076] The hand model driving device 420 is connected to the rear end of the connecting flange 510. Figure 5 As shown, the hand model driving device 420 is a first crank-connecting rod mechanism for driving the hand model assembly 410 to reciprocate up and down, and the grabbing motor 421 provides power for the movement of the first crank-connecting rod mechanism. The first crank-connecting rod mechanism is provided with a vertical moving circulation cam 422 near the hand model assembly 410. The grabbing motor 421 drives the vertical moving circulation cam 422 to reciprocate up and down, and the movement of the vertical moving circulation cam 422 drives the hand model 411 to be repeatedly inserted into the grabbing test device 600, so as to perform the wear resistance test of the sample to be tested.

[0077] In this specific embodiment, the support device 413 is connected to the hand model driving device 420 through the connecting flange 510. Specifically, the rear end of the connecting flange 510 is connected to the vertical moving cycle cam 422 through bolts so that the connecting flange 510 is connected to the hand model driving device 420, and the front end of the connecting flange 510 is connected to the hand model assembly 410. When the grabbing motor 421 is started, the vertical moving cycle cam 422 performs up and down reciprocating motion, thereby driving the hand model assembly 410 to move up and down together. Of course, the structure and installation method of the hand model driving device 420 can be replaced by other solutions, and are not limited to this. The hand model driving device 420 is installed with a first sensor 430 for measuring displacement.

[0078] In this specific embodiment, the grasping test device 600 includes a ball basket connected to the test bench 100 by bolts and a round ball placed in the ball basket. In order to obtain a better test effect, the ball basket is installed at a position directly below the hand model assembly 410. Specifically, the ball basket can be a ball basket, and the round ball can be a Φ10 plastic ball coated with 180 mesh alumina. During the test, the hand model 411 with the sample to be tested is repeatedly inserted into the ball basket with the round ball through the drive of the hand model driving device 420 to perform a wear test on the protective gloves, especially the wear test on the fingertips of the protective gloves. Of course, the structure and installation method of the grasping test device 600 can be replaced by other schemes, and are not limited to this.

[0079] The grinding rod assembly 710 includes a grinding rod 711 and a grinding rod fixing seat 712 on which the grinding rod 711 is installed. The grinding rod 711 can rotate in the grinding rod fixing seat 712. In order to be closer to the actual working conditions, a heating rod and a temperature sensor for detecting the temperature of the grinding rod 711 are installed in the grinding rod 711. The heating temperature range of the grinding rod 711 can be set to: room temperature ~ 70°C. Specifically, a bearing is arranged between the grinding rod 711 and the grinding rod fixing seat 712. The size of the grinding rod 711 is: Φ40×200, and the grinding rod 711 is a round steel rod. A rotating loading part that provides power for the rotation of the grinding rod 711 is also installed on the fixing part of the grinding rod 711, and the rotating loading part can be a rotating motor 713. The grinding rod fixing seat 712 includes a bottom plate and a grinding rod 711 fixing block installed on the bottom plate, the grinding rod 711 fixing block is installed with the grinding rod 711, and a slideway 820 is installed at the bottom of the bottom plate. Of course, the structure and installation method of the grinding rod assembly 710 can be replaced by other solutions and are not limited thereto.

[0080] The grinding rod 711 fixing member is connected to a grinding rod driving device 720. Figure 6As shown, the grinding rod driving device 720 is used to drive the grinding rod 711 to perform a second crankshaft connecting rod mechanism for pulling and pulling in the hand mold 411, and the pulling and pulling motor 721 provides power for the movement of the second crankshaft connecting rod mechanism. The second crankshaft connecting rod mechanism is provided with a horizontal moving circulating cam 722 near the grinding rod assembly 710, and the horizontal moving circulating cam 722 can reciprocate horizontally, thereby driving the grinding rod 711 to perform repeated pulling and pulling in the hand mold 411, so as to achieve the purpose of performing abrasion resistance test on the test sample. The grinding rod driving device 720 is installed with a second sensor 730 for measuring displacement.

[0081] In this embodiment, the connection between the grinding rod assembly 710 and the grinding rod driving device 720 is achieved by bolting a second connecting member 723 arranged at the lower part of the horizontally moving circulating cam 722 to the bottom plate on the grinding rod driving device 720, and the second connecting member 723 is connected to the horizontally moving circulating cam 722 via bolts.

[0082] During the test, the hand mold 411 with the sample to be tested holds the grinding rod 711, and the grinding rod 711 can be repeatedly pulled in the hand mold 411. The grinding rod 711 itself can rotate to increase the friction force, thereby performing a wear test on the protective gloves, especially the wear test on the thenar muscle (the base of the thumb) of the protective gloves. Of course, the structure and installation method of the grinding rod driving device 720 can be replaced by other solutions, and are not limited to this.

[0083] In this embodiment, the grinding rod assembly 710 and the grinding rod driving device 720 connected thereto are connected to the test bench 100 via a second guide portion 800. The second guide portion 800 includes a convex slide rail 810 and a concave slideway 820 for use in conjunction with each other. The slide rail 810 is installed on the test bench 100, and the slideway 820 is respectively installed at the bottom of the bottom plate of the grinding rod testing device 700 and the bottom of the grinding rod driving device 720. Of course, the structure and installation method of the second guide portion 800 can be replaced by other solutions, and are not limited thereto.

[0084] The second guide portion 800 further includes a horizontal loading portion 830, which may be a cylinder, the telescopic arm of which is connected to the bottom of the grinding rod driving device 720 by bolts, and the cylinder barrel of which is connected to the test bench 100 by bolts. The horizontal loading portion 830 is used to drive the grinding rod assembly 710 and the grinding rod driving device 720 to move horizontally along the second guide portion 800. Slots that do not interfere with the movement of the grinding rod assembly 710 and the grinding rod driving device 720 are provided at corresponding positions of the test bench 100.

[0085] Before the test, the grinding rod assembly 710 and the grinding rod driving device 720 need to be synchronously moved to the position to be tested, that is, close to the hand model 411. After the test, the grinding rod assembly 710 and the grinding rod driving device 720 need to return to their original positions.

[0086] The protective glove wear resistance tester also includes a controller, which is electrically connected to the grabbing motor 421, the rotating motor 713, the pulling motor 721, the horizontal loading part 830, the lifting loading part 540, the first sensor 430 and the second sensor 730. The controller is also connected to a display to transmit the detection data to the display, and the display is connected to a printer to print out the data.

[0087] The working process of the embodiment of the present invention is as follows:

[0088] It should be noted that the maximum outward extension stroke of the telescopic arm of the lifting and loading part 540 is defined as the upper limit position, and the contraction position of the telescopic arm of the lifting and loading part 540 is defined as the lower limit position.

[0089] Grabbing test: Put the plastic ball coated with 180 mesh alumina into the ball basket, fix the ball basket to the test bench 100, and tighten the bolts. Fix the hand mold 411 on the hand mold assembly 410, and put on the test sample. Parameter setting, set the material grabbing cycle (for example, the time for one up and down cycle, 2-10s) and the number of material grabbing times. The lifting and loading part 540 drives the hand mold 411 to automatically descend to the lower limit, and the grabbing motor 421 drives the hand mold 411 to move up and down in the ball basket. One up and down is a cycle. At this time, the number of material grabbing times on the display increases by one until the set number of grabbing times is completed, the grabbing motor 421 stops, and the hand mold 411 automatically rises to the upper limit. The test report screen is displayed on the display, and the report automatically produces relevant measurement parameters. The controller is connected to the printer, and the test report can be exported to Excel file and printed.

[0090] It should be noted that the maximum outward extension stroke of the telescopic arm of the horizontal loading part 830 is defined as the left limit, and the contraction point of the telescopic arm of the horizontal loading part 830 is defined as the right limit.

[0091] Stick grip test: The grinding rod 711 is fixed on the grinding rod fixing seat 712. The hand model 411 is fixed on the hand model assembly 410, powered on, and the test sample is put on. Parameter setting, set the grinding rod 711 temperature, grinding rod 711 rotation speed (5r / min-100r / min), pulling speed (1mm / s-15mm / s), pulling times and hand opening frequency (i.e., the hand is opened once after pulling several times). The horizontal loading part 830 drives the grinding rod 711 to move toward the hand model 411 until it reaches the right limit, and the hand model 411 automatically drops to the lower limit. The controller controls the hand model 411 to hold the grinding rod 711 tightly, and the rotating motor 713 drives the grinding rod 711 to rotate. At the same time, the pulling motor 721 drives the grinding rod 711 to pull left and right. The hand model 411 opens once every several times (set the hand opening frequency, for example, if it is set to 5, it will open once after 5 times of pulling), until the set number of pulling is completed, the rotating motor 713 and the pulling motor 721 stop running, the hand model 411 opens, and the horizontal loading part 830 drives the grinding rod 711 to move away from the hand model 411 until it reaches the left limit, and the hand model 411 rises to the upper limit. The test report screen is displayed on the display, and the report automatically produces relevant measurement parameters. The controller is connected to a printer, and the test report can be exported to an Excel file for printing.
