Description

Technical Field

[0001] The utility model relates to the technical field of plate detection, in particular to a tool for testing the surface roughness of a plate. Background Art

[0002] After the production of artificial stone slabs, their surface roughness is tested. Usually, a probe-type roughness meter is used. Its working principle is that the probe, under the control of the driving mechanism, moves along the surface of the artificial stone slab in a straight line or a prescribed trajectory (such as an arc) at a constant speed to scan the surface point by point. When the probe moves with the fluctuation of the surface contour, its vertical displacement will be sensitively detected.

[0003] The detection type roughness tester is usually installed on its own lifting bracket for detection. The existing lifting bracket can only be adjusted in height, but not in pitch angle. As a result, the roughness test can only be performed on the flat surface. It cannot fit the inclined or curved plates. In the absence of pitch angle adjustment, the user may need to frequently adjust the position of the equipment to adapt to different measurement angles. In addition, the existing clamping mechanism and the roughness tester are mostly fixed by a bolt-type structure, resulting in low installation efficiency of the roughness tester, which increases the complexity and time cost of the operation. Therefore, a plate surface roughness test tool is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a tooling for testing the surface roughness of a plate, which has the advantages of being adjustable in multiple ranges and angles and convenient to install, and solves the problem that the existing roughness tester cannot adapt to inclined or curved plates and the roughness tester and the support frame are inconvenient to install.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tool for testing the surface roughness of a plate, comprising a support plate, a longitudinal slide rod and a clamping table, wherein a distance adjustment mechanism and an angle adjustment mechanism are arranged between the longitudinal slide rod and the clamping table;

[0006] The longitudinal slide rod is rotatably connected to the support plate, and a first slide groove is provided on the longitudinal slide rod, a first screw rod is provided in the first slide groove, the distance adjustment mechanism includes a suspension arm, a slider and a second screw rod, the suspension arm is inserted into the first slide groove and is threadedly connected to the first screw rod, a second slide groove is provided on the side of the suspension arm, the slider is inserted into the second slide groove and is threadedly connected to the second screw rod, and the angle adjustment mechanism includes a rotating shaft, a locking nut and a scale plate.

[0007] As a preferred tool for testing the surface roughness of a plate material of the utility model, the rotating shaft is fixedly mounted on the side end surface of the slider, an axial hole is provided on the side surface of the clamping table, and the clamping table and the slider are threadedly connected through the rotating shaft and the axial hole.

[0008] As a preferred tool for testing the surface roughness of a plate of the utility model, the end of the rotating shaft is provided with an external thread, and the locking nut is sleeved on the rotating shaft and is threadedly connected thereto.

[0009] As a preferred tool for testing the surface roughness of a plate of the utility model, the outer end surface of the clamping table near the axial hole is provided with a scale line, the scale plate is fixedly mounted on the side end surface of the slider, and the scale plate is located at the upper end of the scale line.

[0010] As a preferred tool for testing the surface roughness of a plate material of the utility model, the clamping platform includes a fixed platform and a clamping plate, a guide hole is provided on the side of the fixed platform, a guide rod is provided on the side of the clamping plate, the clamping plate and the fixed platform are slidably connected through the guide hole and the guide rod, a limiting plate and a spring are provided on the guide rod, and the clamping plate and the fixed platform are elastically connected through the spring.

[0012] As a preferred tool for testing the surface roughness of a plate of the utility model, hand wheels are provided at the ends of the first screw rod and the second screw rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model realizes precise adjustment of the distance between the longitudinal slide rod and the clamping table through the cooperation of the first screw rod, the boom slider and the second screw rod, so that the tooling can adapt to the detection needs of plates of different thicknesses or depths, and improves the versatility of the equipment. The shaft design enables the clamping table to adjust the pitch angle, which is particularly suitable for the detection of curved or inclined structural plates, ensuring that the roughness tester can fit closely to the measured surface and improve the measurement accuracy. The coordinated use of the scale plate and the scale line enables the operator to intuitively read and accurately set the pitch angle of the clamping table, which is conducive to the precise measurement of plates with specific inclination angles and enhances the controllability of the measurement process and the reliability of the results.

[0015] 2. The utility model realizes automatic resetting of the clamping plate by cooperating with the guide hole, the guide rod and the spring. This design makes the installation and disassembly of the roughness meter more convenient. The instrument only needs to be placed on the fixed table, and the clamping plate can be automatically clamped under the action of the spring, which significantly improves the work efficiency. Through the cooperation of the limit plate and the adjusting nut, the user can flexibly adjust the compression stroke of the spring according to the size and weight of the instrument to be tested, thereby changing the clamping force of the clamping plate, ensuring that roughness meters of different sizes and weights can be firmly and stably clamped and fixed, avoiding measurement errors caused by unstable clamping.

[0022] The longitudinal slide rod 2 is rotatably connected to the support plate 1, and a first slide groove 201 is arranged on the longitudinal slide rod 2, and a first screw rod 202 is arranged in the first slide groove 201. The distance adjustment mechanism 3 includes a suspension arm 310, a slider 303 and a second screw rod 302. The suspension arm 310 is inserted into the first slide groove 201 and is threadedly connected to the first screw rod 202. A second slide groove 301 is arranged on the side of the suspension arm 310, and the slider 303 is inserted into the second slide groove 301 and is threadedly connected to the second screw rod 302. The angle adjustment mechanism 4 includes a rotating shaft 410, a locking nut 430 and a scale plate 420.

[0023] Furthermore, the rotating shaft 410 is fixedly mounted on the side end surface of the slider 303 , and the side surface of the clamping platform 5 is provided with an axial hole 511 , and the clamping platform 5 and the slider 303 are threadedly connected through the rotating shaft 410 and the axial hole 511 .

[0024] The pitch angle of the rotatably connected clamping table 5 can be adjusted, so that the roughness tester can be rotated when testing the curved surface, thereby maintaining fit with the curved surface plate material, thereby improving the application range of the equipment.

[0025] Furthermore, an external thread is provided at the end of the rotating shaft 410 , and the locking nut 430 is sleeved on the rotating shaft 410 and threadedly connected thereto.

[0026] The locking nut 430 is rotated to press the clamping platform 5 together with the slider 303, thereby fixing the clamping platform 5 and keeping it at a certain angle to adapt to the detection of flat plate materials.

[0027] Furthermore, a scale line 440 is provided on the outer end surface of the clamping platform 5 near the shaft hole 511 , and the scale plate 420 is fixedly mounted on the side end surface of the slider 303 , and the scale plate 420 is located above the scale line 440 .

[0028] When the clamping platform 5 is rotated, the scale plate 420 points to different scale lines 440, so that the current pitch angle of the clamping platform 5 can be easily observed, so as to accurately measure the plate of the inclined structure.

[0029] Furthermore, the clamping platform 5 includes a fixed platform 510 and a clamping plate 520, a guide hole 512 is provided on the side of the fixed platform 510, a guide rod 521 is provided on the side of the clamping plate 520, the clamping plate 520 and the fixed platform 510 are slidably connected through the guide hole 512 and the guide rod 521, a limiting plate 524 and a spring 522 are provided on the guide rod 521, and the clamping plate 520 and the fixed platform 510 are elastically connected through the spring 522.

[0030] The clamping plate 520 automatically moves toward the end of the fixing platform 510 under the resetting action of the spring 522, thereby automatically clamping the roughness meter, thereby improving the convenience of installation and disassembly of the roughness meter.

[0031] Furthermore, the limiting plate 524 is slidably connected to the guide rod 521 , an external thread is provided at the end of the guide rod 521 , and an adjusting nut 523 is provided on the guide rod 521 .

[0033] Furthermore, hand wheels 203 are provided at the ends of the first screw rod 202 and the second screw rod 302 .

[0034] The first screw rod 202 and the second screw rod 302 can be conveniently and quickly rotated by the hand wheel 203, so as to facilitate the rapid adjustment of the spatial position of the clamping platform 5, so as to facilitate the detection of different areas of the plate.

[0035] When the device is in use, according to the thickness of the plate to be tested or the position to be tested, the distance between the longitudinal slide rod 2 and the clamping platform 5 is adjusted by operating the first screw rod 202 and the second screw rod 302 to ensure that the detection head of the roughness tester can accurately contact the surface of the plate. For flat plates, the clamping platform 5 can be kept in a horizontal position; for curved plates, loosen the locking nut 430 and rotate the clamping platform 5 to the required pitch angle so that the detection probe of the device can fit the curved plate when it is contracted. For inclined structural plates, refer to the scale plate 420 and the scale line 440 and rotate the clamping platform 5 to The same inclination as the plate, then, tighten the locking nut 430 to ensure the accuracy of the angle setting, so that the detection probe is parallel to the surface of the plate.

The clamp 520 will automatically move closer to the end of the fixed table 510 under the action of the spring 522 to clamp the tester. If you need to adjust the clamping force, rotate the adjusting nut 523 to adapt the size and weight of the tester by changing the compression stroke of the spring 522 to ensure that the instrument is clamped firmly and stably.
