Description

[0003] The problem with the existing technology is that the traditional testing device can only test a single position of the wire mesh at a time when in operation. When testing other positions, another control machine is required to turn the test structure. This is very time-consuming and labor-intensive, and has low efficiency when a large number of wire meshes need to be tested. Therefore, we propose a nickel alloy screen strength testing device.

The motor is fixedly connected to the middle part of the bottom plate, the screw rod is fixedly connected to the output end of the motor, and a support frame is provided on the surface of the screw rod.

[0007] The surface of the screw rod is threadedly connected to a threaded block, and both sides of the threaded block are fixedly connected to a rotating column. A smooth area is provided at one end of the screw rod surface, and the two groups of telescopic rods are respectively rotatably connected to the surfaces of the two groups of rotating columns;

[0008] One end of the two groups of telescopic rods are rotatably connected to a connecting rod, and the four groups of mobile frames are respectively fixedly connected to the two ends of the two groups of connecting rods. The four groups of mobile frames are slidably connected to the limit plates, and the limit plates are fixedly connected to the surface of the vertical plates. One end of the corresponding two groups of mobile frames are commonly fixedly connected to a clamping shell.

[0009] As a preferred embodiment of the present invention, the test assembly includes a first rotating shaft, a connecting plate and a turntable, the first rotating shaft is rotatably connected to one end of the screw rod, the other side of the first rotating shaft is fixedly connected to a placing plate, and the inside of the placing plate is rotatably connected to a second rotating shaft.

[0010] As a preferred embodiment of the present invention, a spring is sleeved on the surface of the screw rod, one end of the spring is fixedly connected to a movable plate, six groups of positioning rods are fixedly connected to the upper surface of the movable plate, and the connecting plate is fixedly connected to the upper end of the release plate.

[0011] As a preferred embodiment of the present invention, three groups of sliding shells are fixedly connected to the upper end of the connecting plate, the interiors of the three groups of sliding shells are slidably connected to sliders, and the surfaces of the three groups of sliders are fixedly connected to two groups of fixed plates.

[0012] As a preferred embodiment of the present invention, the turntable is movably connected between six groups of fixed plates, the surface of the turntable is provided with moving grooves corresponding to the sliders, one end of the three groups of sliders are provided with rollers, and the surface of the turntable is provided with holes for positioning the positioning rods.

[0013] A nickel alloy screen mesh strength testing method, applied to the above-mentioned nickel alloy screen mesh strength testing device, comprises the following steps:

[0014] S1, according to the usage method, can be divided into screen position fixation and strength test;

[0015] S11, when the position is fixed, the operation of the motor drives the threaded block to move on the surface of the screw rod, thereby using the telescopic rod to pull the moving frame and the clamping shell to move and clamp the wire mesh;

[0016] S12, when performing strength testing, as the threaded block moves upward, it will drive the moving plate and the positioning rod to move upward synchronously and be positioned inside the turntable, so that the turntable is driven by the screw rod to rotate, and the moving groove can drive the roller to roll back and forth on the surface of the wire mesh to perform strength testing;

[0017] S2, complete the operation steps corresponding to each usage method;

[0018] S21, when the motor is running, the threaded block moves upward on the surface of the screw rod. During the movement, since the two ends of the telescopic rod are respectively connected to the rotating column and the connecting rod in a rotational manner, the telescopic rod pulls the movable frame to move on the surface of the limit block, thereby driving the clamping shell to move and fix the position of the wire mesh. The limit plate is used to limit the movement of the movable frame;

[0019] S22, when the threaded block moves upward, it will push the moving plate and the positioning rod upward, and position the positioning rod inside the turntable. There is no threaded connection between the moving plate and the screw rod. When the threaded block moves to the smooth area on the screw rod surface, the threaded block will fix the moving plate on the surface of the first rotating shaft, and the rotational friction of the second rotating shaft is greater than the rotational friction of the first rotating shaft. Therefore, when the screw rod drives the first rotating shaft to rotate, the first rotating shaft will not drive the second rotating shaft to rotate. Therefore, when the moving plate is fixed, the three sets of positioning rods in the middle and the three sets of positioning rods on the outside will be positioned respectively. Inside the holes in the middle and outside of the turntable, the three sets of positioning rods in the middle will pass through the second rotating shaft. At this time, the rotation of the screw will use the positioning rod to drive the turntable to rotate. The spring is used to connect the moving plate. Due to the design of the moving groove, when the turntable rotates, the slider will reciprocate inside the sliding shell, thereby driving the roller to roll back and forth on the surface of the wire mesh for testing. The fixed plate is used to support the turntable. When the motor drives the screw to run in the opposite direction, the clamping assembly will disengage from the clamping of the wire mesh, and the test assembly will also stop testing the wire mesh. The clamping assembly and the test assembly run synchronously.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When in use, the present invention places the wire mesh on the upper ends of two sets of vertical plates, and then starts the clamping assembly to fix the position of the wire mesh, which will drive the test assembly to run synchronously, thereby performing a strength test on the surface of the wire mesh, thereby improving the test efficiency and preventing inaccurate testing due to the movement of the wire mesh during the test.

[0022] 2. The present invention causes the threaded block to move upward on the surface of the screw rod when the motor is running. During the movement, since the two ends of the telescopic rod are rotationally connected to the rotating column and the connecting rod respectively (to prevent jamming), the telescopic rod will pull the mobile frame to move on the surface of the limit block, thereby driving the clamping shell to move to fix the position of the wire mesh. The limit plate is used to limit the movement of the mobile frame, thereby preventing the wire mesh from moving when being tested.

[0023] 3. The present invention pushes the movable plate and the positioning rod upward when the threaded block moves upward, and positions the positioning rod inside the turntable. There is no threaded connection between the movable plate and the screw rod. When the threaded block moves to the smooth area on the screw rod surface without threads, the threaded block will fix the movable plate on the surface of the first rotating shaft, and the rotational friction of the second rotating shaft is greater than the rotational friction of the first rotating shaft. Therefore, when the screw rod drives the first rotating shaft to rotate, the first rotating shaft will not drive the second rotating shaft to rotate. Therefore, when the movable plate is fixed, the three sets of positioning rods in the middle and the three sets of positioning rods on the outside will be positioned in the middle and outside of the turntable respectively. Inside the hole in the top, the three sets of positioning rods in the middle will pass through the second rotating shaft. At this time, the rotation of the screw will use the positioning rod to drive the turntable to rotate. The spring is used to connect the moving plate. Due to the design of the moving groove, when the turntable rotates, the slider will reciprocate inside the sliding shell, thereby driving the roller to roll back and forth on the surface of the wire mesh for testing. The fixed plate is used to support the turntable. When the motor drives the screw to run in the opposite direction, the clamping assembly will disengage from the clamping of the wire mesh, and the test assembly will also stop testing the wire mesh. The clamping assembly and the test assembly run synchronously, which can effectively improve the testing efficiency of the wire mesh. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0033] The structure of the present invention is described in detail below with reference to the accompanying drawings.

[0034] Example:

[0035] like Figures 1 to 7 As shown, an embodiment of the present invention provides a nickel alloy screen strength testing device, comprising a bottom plate 1, a vertical plate 3 and a limit block 5, wherein two groups of vertical plates 3 are fixedly connected to both sides of the upper surface of the bottom plate 1, respectively, and four groups of limit blocks 5 are fixedly connected to the lower surfaces of the two groups of vertical plates 3, respectively. The lower surfaces of the four groups of limit blocks 5 are all slidably connected to a clamping assembly 2, and a testing assembly 4 is provided on the surface of the clamping assembly 2. The clamping assembly 2 is used to fix the position of the screen, and the testing assembly 4 is used to test the strength of the screen.

[0036] The clamping assembly 2 includes a motor 210, a screw rod 209, a telescopic rod 205 and a mobile frame 201. The motor 210 is fixedly connected to the middle part of the bottom plate 1, the screw rod 209 is fixedly connected to the output end of the motor 210, and a support frame 211 is provided on the surface of the screw rod 209; a threaded block 207 is threadedly connected to the surface of the screw rod 209, and both sides of the screw block 207 are fixedly connected to the rotating column 206. A smooth area 208 is provided on the surface of the screw rod 209. The two groups of telescopic rods 205 are rotatably connected to the surfaces of the two groups of rotating columns 206 respectively; one end of the two groups of telescopic rods 205 are rotatably connected to the connecting rod 204, and the four groups of mobile frames 201 are respectively fixedly connected to the two ends of the two groups of connecting rods 204. The four groups of mobile frames 201 are all slidably connected to the limit plate 202 inside, and the limit plate 202 is fixedly connected to the surface of the vertical plate 3. One end of the corresponding two groups of mobile frames 201 is commonly fixedly connected to the clamping shell 203;

[0037] The test assembly 4 includes a first rotating shaft 405, a connecting plate 401 and a turntable 408. The first rotating shaft 405 is rotatably connected to one end of the screw rod 209. The other side of the first rotating shaft 405 is fixedly connected to a placing plate 407. The placing plate 407 is internally rotatably connected to a second rotating shaft 406. A spring 404 is sleeved on the surface of the screw rod 209. One end of the spring 404 is fixedly connected to a moving plate 403. The upper surface of the moving plate 403 is fixedly connected to six groups of positioning rods 402. The connecting plate 401 is fixedly connected to the placing plate 4 07 upper end; three groups of sliding shells 409 are fixedly connected to the upper end of the connecting plate 401, and sliders 410 are slidably connected inside the three groups of sliding shells 409, and two groups of fixed plates 413 are fixedly connected to the surfaces of the three groups of sliders 410; the turntable 408 is movably connected between the six groups of fixed plates 413, and the surface of the turntable 408 is provided with moving grooves 412 corresponding to the sliders 410, and one end of the three groups of sliders 410 is provided with rollers 411, and the surface of the turntable 408 is provided with holes for positioning the positioning rod 402.

[0038] The above solution is adopted: when in use, the screen is placed on the upper ends of the two sets of vertical plates 3, and then the clamping assembly 2 is started to fix the position of the screen, which will drive the testing assembly 4 to run synchronously, thereby performing a strength test on the surface of the screen, thereby improving the test efficiency and preventing inaccurate testing caused by the movement of the screen during the test;

[0039] When the motor 210 is running, the threaded block 207 moves upward on the surface of the screw rod 209. During the movement, since the two ends of the telescopic rod 205 are respectively connected to the rotating column 206 and the connecting rod 204 in a rotational manner (to prevent jamming), the telescopic rod 205 pulls the movable frame 201 to move on the surface of the limit block 5, thereby driving the clamping shell 203 to move and fix the position of the wire mesh. The limit plate 202 is used to limit the movement of the movable frame 201, thereby preventing the wire mesh from moving when being tested.

[0040] When the threaded block 207 moves upward, it pushes the movable plate 403 and the positioning rod 402 upward, and positions the positioning rod 402 inside the turntable 408. There is no threaded connection between the movable plate 403 and the screw rod 209. When the threaded block 207 moves to the smooth area 208 on the surface of the screw rod 209 without threads, the threaded block 207 will fix the movable plate 403 on the surface of the first rotating shaft 405, and the rotational friction of the second rotating shaft 406 is greater than the rotational friction of the first rotating shaft 405. Therefore, when the screw rod 209 drives the first rotating shaft 405 to rotate, the first rotating shaft 405 will not drive the second rotating shaft 406 to rotate. Therefore, when the movable plate 403 is fixed, the three groups of positioning rods 402 in the middle and the three groups of positioning rods 402 on the outside will be positioned on the turntable 408 respectively. The three sets of positioning rods 402 in the middle and outside of the holes will pass through the second rotating shaft 406. At this time, the rotation of the screw rod 209 will use the positioning rod 402 to drive the turntable 408 to rotate. The spring 404 is used to connect the movable plate 403. Due to the design of the movable groove 412, when the turntable 408 rotates, the slider 410 will reciprocate inside the sliding shell 409, thereby driving the roller 411 to roll back and forth on the surface of the wire mesh for testing. The fixed plate 413 is used to support the turntable 408. When the motor 210 drives the screw rod 209 to run in the opposite direction, the clamping assembly 2 disengages from the clamping of the wire mesh, and the test assembly 4 will also stop testing the wire mesh. The clamping assembly 2 and the test assembly 4 run synchronously, which can effectively improve the testing efficiency of the wire mesh.

[0041] like Figure 1-7 As shown, a nickel alloy screen screen strength testing method, using the above-mentioned nickel alloy screen screen strength testing device, includes the following steps:

[0042] S1, according to the usage method, can be divided into screen position fixation and strength test;

[0043] S11, when the position is fixed, the operation of the motor 210 drives the threaded block 207 to move on the surface of the screw rod 209, thereby using the telescopic rod 205 to pull the movable frame 201 and the clamping shell 203 to move and clamp the screen;

[0044] S12, when performing strength testing, as the screw block 207 moves upward, the movable plate 403 and the positioning rod 402 will be synchronously moved upward and positioned inside the turntable 408, so that the turntable 408 is rotated by the screw rod 209, and the movable groove 412 can drive the roller 411 to roll back and forth on the surface of the screen to perform strength testing;

[0045] S2, complete the operation steps corresponding to each usage method;

[0046] S21, when the motor 210 is running, the threaded block 207 moves upward on the surface of the screw rod 209. During the movement, since the two ends of the telescopic rod 205 are respectively connected to the rotating column 206 and the connecting rod 204 in a rotational manner (to prevent jamming), the telescopic rod 205 pulls the movable frame 201 to move on the surface of the limit block 5, thereby driving the clamping shell 203 to move and fix the position of the wire mesh. The limit plate 202 is used to limit the movement of the movable frame 201, thereby preventing the wire mesh from moving during testing.

[0047] S22, when the threaded block 207 moves up, it will push the movable plate 403 and the positioning rod 402 to move up, and position the positioning rod 402 inside the turntable 408. There is no threaded connection between the movable plate 403 and the screw rod 209. When the threaded block 207 moves to the smooth area 208 on the surface of the screw rod 209 without threads, the threaded block 207 will fix the movable plate 403 on the surface of the first rotating shaft 405, and the rotational friction of the second rotating shaft 406 is greater than the rotational friction of the first rotating shaft 405. Therefore, when the screw rod 209 drives the first rotating shaft 405 to rotate, the first rotating shaft 405 will not drive the second rotating shaft 406 to rotate. Therefore, when the movable plate 403 is fixed, the three sets of positioning rods 402 in the middle and the three sets of positioning rods 402 on the outside will be positioned on the turntable 408 respectively. 08, the three sets of positioning rods 402 in the middle and outside of the hole will pass through the second rotating shaft 406. At this time, the rotation of the screw rod 209 will use the positioning rod 402 to drive the turntable 408 to rotate. The spring 404 is used to connect the movable plate 403. Due to the design of the movable groove 412, when the turntable 408 rotates, the slider 410 will reciprocate inside the sliding shell 409, thereby driving the roller 411 to roll back and forth on the surface of the wire mesh for testing. The fixed plate 413 is used to support the turntable 408. When the motor 210 drives the screw rod 209 to run in the opposite direction, the clamping assembly 2 disengages from the clamping of the wire mesh, and the test assembly 4 will also stop testing the wire mesh. The clamping assembly 2 and the test assembly 4 run synchronously, which can effectively improve the testing efficiency of the wire mesh.

[0048] Working principle of the present invention:

[0049] During use, when the motor 210 is running, the threaded block 207 will move upward on the surface of the screw rod 209. During the movement, since the two ends of the telescopic rod 205 are respectively connected to the rotating column 206 and the connecting rod 204 in a rotational manner (to prevent jamming), the telescopic rod 205 will pull the mobile frame 201 to move on the surface of the limit block 5, thereby driving the clamping shell 203 to move and fix the position of the wire mesh. The limit plate 202 is used to limit the movement of the mobile frame 201, so as to prevent the wire mesh from being stuck during testing. The effect of position movement occurs. When the threaded block 207 moves upward, it pushes the movable plate 403 and the positioning rod 402 to move upward, and positions the positioning rod 402 inside the turntable 408. There is no threaded connection between the movable plate 403 and the screw rod 209. When the threaded block 207 moves to the smooth area 208 on the surface of the screw rod 209 without threads, the threaded block 207 will fix the movable plate 403 on the surface of the first rotating shaft 405, and the rotational friction force of the second rotating shaft 406 is greater than the rotational friction force of the first rotating shaft 405. When the screw rod 209 drives the first rotating shaft 405 to rotate, the first rotating shaft 405 does not drive the second rotating shaft 406 to rotate. Therefore, when the movable plate 403 is fixed, the three sets of positioning rods 402 in the middle and the three sets of positioning rods 402 on the outside will be positioned in the middle and outer holes of the rotating disk 408 respectively. The three sets of positioning rods 402 in the middle will pass through the second rotating shaft 406. At this time, the rotation of the screw rod 209 will use the positioning rods 402 to drive the rotating disk 408 to rotate. The spring 404 is used to connect the movable plate 403 Due to the design of the movable groove 412, when the turntable 408 rotates, the slider 410 will reciprocate inside the sliding shell 409, thereby driving the roller 411 to roll back and forth on the surface of the wire mesh for testing. The fixed plate 413 is used to support the turntable 408. When the motor 210 drives the screw rod 209 to run in the reverse direction, the clamping component 2 disengages from the clamping of the wire mesh, and the test component 4 will also stop testing the wire mesh. The clamping component 2 and the test component 4 operate synchronously, which can effectively improve the testing efficiency of the wire mesh.

[0050] To sum up: this nickel alloy screen strength testing device, through the structure of connecting plate 401, positioning rod 402, movable plate 403, spring 404, first rotating shaft 405, second rotating shaft 406, placing plate 407, turntable 408, sliding shell 409, slider 410, roller 411, movable groove 412 and fixed plate 413, solves the problem that traditional testing devices can only test a single position of the screen at a time during operation. When testing other positions, another control machine is required to turn the test structure. This will be very time-consuming and labor-intensive and inefficient when a large number of screens need to be tested.

During the movement, since the two ends of the telescopic rod (205) are respectively connected to the rotating column (206) and the connecting rod (204) in a rotational manner, the telescopic rod (205) pulls the movable frame (201) to move on the surface of the limit block (5), thereby driving the clamping shell (203) to move to fix the position of the wire mesh. The limit plate (202) is used to limit the movement of the movable frame (201); S22, when the threaded block (207) moves upward, it pushes the movable plate (403) and the positioning rod (402) to move upward, and positions the positioning rod (402) inside the turntable (408). There is no threaded connection between the movable plate (403) and the screw rod (209). When the threaded block (207) moves to the smooth area (208) on the surface of the screw rod (209), the threaded block (207) fixes the movable plate (403) on the surface of the first rotating shaft (405), and the rotational friction of the second rotating shaft (406) is greater than the rotational friction of the first rotating shaft (405). Therefore, when the screw rod (209) drives the first rotating shaft (405) to rotate, the first rotating shaft (405) does not drive the second rotating shaft (406) to rotate. Therefore, when the movable plate (403) is fixed, the three sets of positioning rods (402) in the middle and the three sets of positioning rods (402) on the outside are fixed. ) will be positioned in the middle and outer holes of the turntable (408) respectively, and the three sets of positioning rods (402) in the middle will pass through the second rotating shaft (406). At this time, the rotation of the screw rod (209) will use the positioning rod (402) to drive the turntable (408) to rotate. The spring (404) is used to connect the moving plate (403). Due to the design of the moving groove (412), when the turntable (408) rotates, the slider (410) will reciprocate inside the sliding shell (409), thereby driving the roller (411) to roll back and forth on the surface of the wire mesh for testing. The fixed plate (413) is used to support the turntable (408). When the motor (210) drives the screw rod (209) to run in the reverse direction, the clamping component (2) disengages from the clamping of the wire mesh, and the test component (4) will also stop testing the wire mesh. The clamping component (2) and the test component (4) run synchronously.
