Abstract
Description
Technical Field
[0001] This invention relates to the field of roughness testing equipment technology, specifically to a steel plate roughness testing instrument with an adjustment mechanism. Background Technology
[0002] Surface roughness is one of the key indicators for evaluating the quality of steel plates. Contact roughness testers (usually composed of an instrument body, a measuring rod, and a measuring head) are commonly used tools for this test in the field. Currently, these testers are easy to operate when measuring horizontally placed steel plates, as they can be placed directly on the surface for measurement.
[0003] However, in actual production, to save storage and operating space, large quantities of steel plates are often stored vertically or at an angle. Under such conditions, traditional surface roughness testers face significant problems: First, the tester cannot be automatically fixed on inclined or vertical steel plates, relying entirely on manual operation by the inspector. This not only makes it difficult for the inspector to simultaneously read and record data, resulting in low efficiency, but also easily leads to instrument vibration due to fatigue during prolonged operation, introducing measurement errors and affecting the accuracy of the results. Second, different steel plates have varying thicknesses, and existing testers lack a universal clamping mechanism, making it impossible to quickly adapt to workpieces of different thicknesses, thus limiting their application range.
[0004] Therefore, there is an urgent need for a solution that can stably and reliably fix a standard roughness tester on the surface of inclined or vertical steel plates, freeing up the operator's hands, and having versatility to adapt to different plate thicknesses, thereby improving testing efficiency and accuracy. Utility Model Content
[0005] In order to overcome the above-mentioned technical problems, the purpose of this invention is to provide a steel plate roughness tester with an adjustment mechanism to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A steel plate roughness tester with an adjustment mechanism includes a tester comprising an instrument body, a test rod, and a test head. The test rod is connected between the instrument body and the test head. The instrument body has a side connection mechanism and a telescopic mechanism mounted on its side. The side connection mechanism is used for quick-release connection of the test rod and includes a connecting block and a pressure plate. The pressure plate is rotatably connected to the connecting block, and the pressure plate and connecting block press against the test rod. A gasket is provided on one side of the connecting block, and the connecting block contacts the instrument body through the gasket. A bolt is threadedly connected to the back of the connecting block. The telescopic mechanism is used to place the tester on an inclined steel plate for testing. The telescopic mechanism includes a lead screw, on which an adjustment knob is fixedly connected. The lead screw is connected to a horizontal strip via a nut pair, and a clamping rod is fixedly connected to the horizontal strip. The clamping rod and the test head cooperate to clamp the tester onto the steel plate.
[0007] Preferably, the connecting block and the pressure plate are provided with grooves corresponding to the detection rod, and the pressure plate is provided with a rubber protective pad at the position where it contacts the detection rod, so that the pressure plate contacts the detection rod through the rubber protective pad.
[0008] Preferably, a latch is provided on one side of the connecting block. The latch is connected to the connecting block via a rotating shaft. The latch contacts the pressure plate via a slot. When the latch contacts the pressure plate via the slot, the pressure plate is locked.
[0009] Preferably, the gasket has a groove corresponding to the detection rod, and the surface of the gasket has protective texture.
[0010] Preferably, the surface of the adjusting knob is provided with anti-slip texture, the lead screw is rotatably connected to the connecting block, and one end of the bolt is in contact with the surface of the clamping rod.
[0011] Preferably, the horizontal strip is slidably connected to the connecting block via a groove, and the end of the clamping rod away from the horizontal strip is in contact with the detection head.
[0012] Preferably, the clamping rod and the crossbar are made of plastic.
[0013] Preferably, the connecting block is provided with a sliding groove corresponding to the clamping rod, and the connecting block and the clamping rod slide in contact through the sliding groove.
[0014] Preferably, the clamping rod is L-shaped, and the surface of the clamping rod is provided with anti-slip texture.
[0015] Preferably, the connecting block has a slot for connecting with a hook.
[0016] Compared with the prior art, the beneficial effects of the present invention are: The side connection mechanism, consisting of a connecting block, a pressure plate, and a latch, enables quick and easy assembly and disassembly between the instrument body and the adjustment mechanism. Operators only need to insert the detection rod, press down the pressure plate, and lock the latch to complete the installation. The process is simple and efficient. This design not only ensures a firm and reliable connection but also facilitates the quick disassembly of the instrument for routine planar measurement, greatly enhancing the versatility and flexibility of the equipment. The telescopic mechanism, consisting of a lead screw, adjusting knob, crossbar, and clamping rod, works in conjunction with the detection head to form an adjustable "jaw." This design allows the entire detector to be stably clamped onto the edge of a vertically or inclined steel plate, eliminating the need for manual support during measurement. This completely frees the operator's hands, allowing them to focus on reading and recording, which not only improves detection efficiency but also effectively avoids measurement errors caused by hand tremors, ensuring data accuracy. The telescopic mechanism achieves precise linear transmission through a screw and nut pair, allowing for stepless adjustment of the distance between the clamping rod and the detection head. This design enables the device to adapt to steel plates of different thicknesses, making it highly versatile. Furthermore, the anti-slip texture on the surface of the clamping rod and the optional bolt locking function further ensure the stability of the clamping and prevent slippage during measurement, making it suitable for diverse industrial environments.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] One embodiment provided by the present invention: refer to Figure 1 and Figure 2 A steel plate roughness tester with an adjustment mechanism includes a tester comprising an instrument body 11, a test rod 12, and a test head 13, wherein the test rod 12 is connected between the instrument body 11 and the test head 13, wherein: The instrument body 11 is equipped with a side connection mechanism 2 and a telescopic mechanism 3 on its side; refer to Figures 3-5 The side connection mechanism 2 is used for quick-release connection of the detection rod 12. The side connection mechanism 2 includes a connecting block 21 and a pressure plate 22. The pressure plate 22 is rotatably connected to the connecting block 21. The pressure plate 22 and the connecting block 21 press the detection rod 12. A gasket 24 is provided on one side of the connecting block 21. The connecting block 21 contacts the instrument body 11 through the gasket 24. A bolt 211 is threadedly connected to the back of the connecting block 21. The telescopic mechanism 3 is used to place the detector on the inclined steel plate for testing. The telescopic mechanism 3 includes a lead screw 31, an adjustment knob 32 is fixedly connected to the lead screw 31, a crossbar 33 is connected to the lead screw 31 through a nut pair, and a clamping rod 34 is fixedly connected to the crossbar 33. The clamping rod 34 and the detection head 13 cooperate to clamp the detector on the steel plate.
[0021] The connecting block 21 and the pressure plate 22 are provided with grooves corresponding to the detection rod 12. The pressure plate 22 is provided with a rubber protective pad at the position where it contacts the detection rod 12. The pressure plate 22 contacts the detection rod 12 through the rubber protective pad.
[0022] The connecting block 21 is provided with a latch 23 on one side. The latch 23 is connected to the connecting block 21 through a rotating shaft. The latch 23 contacts the pressure plate 22 through a slot. When the latch 23 contacts the pressure plate 22 through the slot, the pressure plate 22 is locked.
[0023] The gasket 24 has a groove corresponding to the detection rod 12, and the surface of the gasket 24 has protective texture.
[0024] The surface of the adjustment knob 32 is provided with anti-slip texture, the lead screw 31 is rotatably connected to the connecting block 21, and one end of the bolt 211 is in contact with the surface of the clamping rod 34.
[0025] The horizontal strip 33 is slidably connected to the connecting block 21 via a groove, and the end of the clamping rod 34 away from the horizontal strip 33 is in contact with the detection head 13.
[0026] The clamping rod 34 and the crossbar 33 are made of plastic.
[0027] The connecting block 21 is provided with a sliding groove corresponding to the clamping rod 34, and the connecting block 21 and the clamping rod 34 slide in contact through the sliding groove.
[0028] The clamping rod 34 is L-shaped, and the surface of the clamping rod 34 is provided with anti-slip texture.
[0029] The connecting block 21 has a slot for connecting with a hook. It should be noted that the slot is for connecting with the hook, so that it can be easily stored on the rack at the detection position or on the operator's work belt.
[0030] refer to Figure 2 It should be noted that the bolt 211 designed on the back of the connecting block 21 is connected to the connecting block 21 by threads. When the bolt 211 is tightened, one end of the bolt 211 rubs against the clamping rod 34 to lock the position of the clamping rod 34. When the bolt 211 is loosened, the locking can be released, which makes it convenient to adjust the clamping rod 34 to adapt to the thickness of the steel plate.
[0031] Working principle: First, the main body of the detector is quickly installed onto the adjustment mechanism via the side connecting mechanism 2. The specific operation is as follows: Place the detection rod 12 into the corresponding groove of the connecting block 21, so that the gasket 24 is in contact with the side of the instrument body 11. Then, rotate the pressure plate 22, so that it and the connecting block 21 clamp the detection rod 12 together. Finally, flip the latch 23, so that it engages with the pressure plate 22, completing the locking process. This process requires no tools, utilizing mechanical interlocking to achieve quick and reliable assembly and disassembly of the detector, and effectively preventing scratches on the detection rod 12 through the rubber protective pad.
[0032] The opening of the clamping mechanism is pre-adjusted according to the thickness of the steel plate to be inspected. The lead screw 31 is driven to rotate by rotating the adjusting knob 32 with anti-slip texture. The lead screw 31 converts the rotational motion into the linear motion of the horizontal bar 33 via the nut pair, thereby causing the L-shaped clamping rod 34 to move closer to or further away from the inspection head 13. This design achieves stepless adjustment of the clamping distance, allowing it to adapt to steel plates of different thicknesses.
[0033] The device is placed on the edge of the steel plate, allowing the plate to embed into the jaws formed by the detection head 13 and the clamping rod 34. Then, the adjustment knob 32 is rotated in the opposite direction, causing the clamping rod 34 to move towards the steel plate, ultimately working in conjunction with the detection head 13 to firmly clamp the steel plate. At this point, the entire detector is stably fixed to the area of the steel plate to be tested under the combined action of its own weight and clamping force. The operator can then free their hands to directly view and record the readings on the instrument body 11, greatly improving testing efficiency and safety.
[0034] The adjustable clamping mechanism transforms the handheld detector into a temporarily fixed testing device, perfectly solving the testing challenges of vertical or inclined plates. The quick-release design of the side connection mechanism 2 ensures that the detector body can still be easily disassembled for traditional planar measurements, balancing functional specialization with usage flexibility.
[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
