Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of thickness gauge auxiliary devices, specifically an auxiliary measuring platform for a split-type coating thickness gauge. Background Technology
[0002] Coating thickness gauges can nondestructively measure the thickness of non-magnetic coatings (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic metal substrates (such as steel, iron, alloys, and hard magnetic steel) and the thickness of non-conductive coatings (such as enamel, rubber, paint, plastic, etc.) on non-magnetic metal substrates (such as copper, aluminum, zinc, tin, etc.).
[0003] The thickness gauge connects to a detection probe that contacts the surface of the object being measured to perform the inspection and obtain the required data.
[0004] However, when testing an object, it is necessary to keep the probe vertical to the object to improve accuracy and reduce errors.
[0005] Therefore, it is necessary to propose a measuring platform that can accurately keep the thickness gauge probe and the object being measured in a vertical position. Utility Model Content
[0006] The purpose of this invention is to provide an auxiliary measuring platform for a split-type coating thickness gauge, so as to solve the above-mentioned technical problems to a certain extent and to better detect the object being measured.
[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes a support platform and an adjustment unit. The adjustment unit includes a support rod vertically fixedly installed on the support platform. A positioning box is sleeved on the outer wall of the support rod. A positioning hole is opened at the top of the positioning box. A lifting rod is vertically arranged inside the positioning hole. The lifting rod passes through a counterweight block disposed inside the positioning box. A guide rod passing through the counterweight block is vertically fixedly installed inside the positioning box. A rotating groove is opened on one side of the counterweight block. A rotating block is rotatably installed inside the rotating groove. An adjustment rod is fixedly installed on one side of the rotating block. A connecting pin passing through the top of the counterweight block is fixedly installed at the top of the rotating block. An L-shaped movable groove is opened on the same side of the positioning box and the adjustment rod.
[0008] The positioning unit includes a fixing mechanism connected to the bottom of the lifting rod. The fixing mechanism includes a positioning block arranged parallel to the positioning box. A positioning handle is fixedly installed on one side of the positioning block. A clamping block is provided in the L-shaped groove of the positioning block. A positioning pin is provided on the same side of the clamping block and the positioning handle. A threaded rod passing through the clamping block and the positioning block is threaded to one side of the clamping block. The top of the positioning block and the clamping block are provided with a diamond-shaped clamping groove facing downward.
[0009] Furthermore, a clamping unit is placed on the upper surface of the support platform. The clamping unit includes a positioning plate, a groove is provided at the center of the positioning plate, a slider is slidably installed inside the groove, a clamping plate is fixedly installed on the top of the slider, and a lead screw passing through the positioning plate is threaded to the side of the slider.
[0010] Furthermore, the adjustment unit also includes a support hole through the positioning box for the support rod to pass through. The positioning box near the end of the support rod is threaded with a bolt that passes through the positioning box and connects to the side hole of the support rod. The outer edge of the support rod is fitted with an annular sleeve located below the positioning box, and the side of the annular sleeve has a through hole.
[0011] Furthermore, the positioning hole passes through the positioning box and the counterweight, and the interior of both the counterweight and the positioning box is rectangular.
[0012] Furthermore, the side area of the movable groove is larger than the side area of the adjusting rod, and the adjusting rod can rotate laterally left and right with the rotating block.
[0013] Furthermore, the clamping block and the positioning block are separately configured, and the threaded rod has an internal thread at the connection point between it and the positioning block and the clamping block.
[0014] Furthermore, the positioning plate has an internal thread on its contact surface with the lead screw, the clamping plate is located above the positioning plate, and the opposing surfaces of the clamping plates are flat.
[0015] Furthermore, the lifting rod is fixedly connected to the inner wall of the counterweight.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. When using this utility model, pull the clamping block away from the positioning block, then place the thickness gauge probe in the clamping groove, keeping the probe's detection end vertically downward. Further move the clamping block towards the positioning block, so that the clamping block and the positioning block limit the probe from both ends. Then screw the threaded rod into the positioning block, thereby limiting the clamping block and fixing the probe, so that the probe is always in a downward state, keeping the probe vertical to the object being measured below, greatly improving the accuracy of the detection.
[0018] 2. In use, the object to be tested is placed between two clamping plates. One clamping plate and the slider are fixed to the positioning plate groove and cannot move. The slider and clamping plate are moved towards the fixed clamping plate by rotating the screw. Thus, the object to be tested can be fixed by the two clamping plates. The positioning plate is not fixed to the support platform, but is for placement. That is, the position of the positioning plate can be adjusted as needed to keep the end of the clamping plate holding the object to be tested directly below the probe, so as to facilitate the probe to detect. It effectively prevents the object to be tested from moving during the detection process, greatly improving the convenience and practicality of the detection.
[0019] 3. In use, this utility model applies an upward force to the adjusting rod or positioning handle, causing the positioning unit to move upward. The lifting rod then rises accordingly. Due to the guide rod and lifting rod, the counterweight can only move up and down without angular deviation. This allows the probe to be easily lifted away from the object being tested during inspection. Then, due to the gravity of the counterweight, when the force on the adjusting rod or positioning handle is removed, the positioning unit falls vertically, allowing the probe to contact the object for inspection. This eliminates the need for constant manual gripping of the probe during inspection, making operation convenient and simple, reducing manpower and alleviating fatigue caused by prolonged testing.
[0020] 4. In this utility model, when it is not necessary to detect an object or when it is necessary to adjust the position of the object to be measured, the positioning unit is lifted upwards, and then a force is applied to the adjusting rod. Through the connecting pin, the rotating block and the adjusting rod can be rotated to the horizontal groove at the top of the movable groove. At this time, the movable groove can block the adjusting rod to prevent it from falling under the action of the counterweight, thereby preventing the probe from moving downwards and contacting the object to be measured on the clamping unit, which facilitates the operator to adjust the object to be measured.
[0021] 5. When using this utility model, the ring can be placed on the lifting rod for height adjustment as needed. Then, the ring is fixed on the lifting rod by passing through the connecting mechanism. This prevents the positioning box and positioning unit from becoming loose and suddenly dropping. It can also prevent the probe installed on the positioning unit from excessively contacting the clamping unit and causing collision damage. This provides protection and reduces damage to the overall device during use. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figure 1-4This utility model provides a technical solution: an auxiliary measuring platform for a split-type coating thickness gauge, including a support platform 100. A clamping unit 400 is placed on the upper surface of the support platform 100. The clamping unit 400 includes a positioning plate 410. A groove 411 is provided at the center of the positioning plate 410. A slider 4111 is slidably installed inside the groove 411. A clamping plate 420 is fixedly installed on the top of the slider 4111. The groove 411 allows the slider 4111 to move parallel to the surface. Furthermore, it can... The slider 4111 is threadedly connected to the side of the top clamping plate 420, and a lead screw 421 passes through the positioning plate 410. The contact surface between the positioning plate 410 and the lead screw 421 is internally threaded. The lead screw 421 causes the slider 4111 and the clamping plate 420 to move in parallel, thereby bringing the two clamping plates 420 closer to each other. The clamping plates 420 are above the positioning plate 410, and the facing surfaces of the clamping plates 420 are flat. The flat surface of the two clamping plates 420 can better contact and fix the object being measured.
[0034] See Figure 1 , Figure 2 In a preferred embodiment, the adjustment unit 200 includes a support rod 110 vertically fixed on the support platform 100. An annular sleeve 130 disposed below the positioning box 210 is sleeved on the outer edge of the support rod 110. A through hole is provided on the side of the annular sleeve 130. The connecting structure can pass through the annular sleeve 130 and contact the support rod 110 through the through hole, thereby fixing the annular sleeve 130 and the support rod 110 together. This can prevent the annular sleeve 130 from moving downward or upward, and can play a role in preventing downward movement from below the positioning box 210.
[0035] See Figure 1 , Figure 2 Preferably, the end of the positioning box 210 near the support rod 110 is threaded with a bolt 120 that passes through the hole on the side of the positioning box 210 and the support rod 110. By connecting the positioning box 210 and the support rod 110 through the bolt, the support rod 110 and the positioning box 210 can be further connected together, maintaining the stability of the connection between the positioning box 210 and the support rod 110 and preventing the positioning box 210 from slipping off the support rod 110. Furthermore, multiple connecting mechanisms can be used to connect the positioning box 210 and the support rod 110 from the other end, making the installation of the positioning box 210 and the support rod 110 together more stable.
[0036] A positioning box 210 is sleeved on the outer wall of the support rod 110. A positioning hole 2111 is opened on the top of the positioning box 210. The positioning hole 2111 passes through the positioning box 210 and the counterweight 220. A lifting rod 21111 is vertically arranged inside the positioning hole 2111. The lifting rod 21111 passes through the counterweight 220 arranged inside the positioning box 210. The lifting rod 21111 and the inner wall of the counterweight 220 are fixedly connected. The interiors of the counterweight 220 and the positioning box 210 are both rectangular. The adjustment unit 200 also includes a support hole 111 that passes through the positioning box 210 for the support rod 110 to pass through.
[0037] The counterweight 220 and the lifting rod 21111 can move up and down together, thereby driving the positioning unit 300, which is fixedly connected to the support rod 110, to move up and down together. The rectangular arrangement of the counterweight 220 can maintain sufficient weight to drive the positioning unit 300 to move downward.
[0038] See Figure 1 , Figure 2 In a further preferred embodiment, a guide rod 240 passing through the counterweight 220 is vertically fixed inside the positioning box 210. When the lifting rod 21111 and the counterweight 220 move up and down, the guide rod 240 guides them to prevent positional and angular deviations during the lifting process. A rotating groove 221 is provided on one side of the counterweight 220, and a rotating block 2211 is rotatably installed inside the rotating groove 221. An adjusting rod 22111 is fixedly installed on one side of the rotating block 2211. The side area of the movable groove 211 is larger than the side area of the adjusting rod 22111, and the adjusting rod 22111 can rotate laterally left and right with the rotating block 2211. A connecting pin 230 is fixedly installed on the top of the 1, passing through the counterweight 220. The positioning box 210 and the adjusting rod 22111 are provided with an L-shaped movable groove 211 on the same side. When the adjusting rod 22111 moves vertically up and down, that is, when it applies and releases force to the counterweight 220, the adjusting rod 22111 moves in the vertical section of the movable groove 211. When the adjusting rod 22111 and the rotating block 2211 rotate, the adjusting rod 22111 can be moved into the horizontal section of the movable groove 211. The movable groove 211 can limit the adjusting rod 22111 to prevent it from moving up and down, thus preventing the counterweight 220 from moving downward.
[0039] See Figure 2 , Figure 3 and Figure 4In a further preferred embodiment, the positioning unit 300 includes a fixing mechanism 310 connected to the bottom of the lifting rod 21111. The fixing mechanism 310 includes a positioning block 311 arranged parallel to the positioning box 210. A positioning handle 3111 is fixedly installed on one side of the positioning block 311. The fixing mechanism 310 can be lifted upward by applying force through the positioning handle 3111. At this time, the lifting rod 21111 and the counterweight 220 move upward synchronously. A clamping block 320 is provided in the L-shaped groove of the positioning block 311. The clamping block 320 and the positioning block 311 are separately arranged. A positioning pin 321 is provided on the same side of the clamping block 320 and the positioning handle 3111. The positioning pin 321 ensures that the clamping block 320 will not fall off when separated from the positioning block 311. It can be extended and supported by the positioning pin 321 to prevent it from falling off.
[0040] One side of the clamping block 320 is threadedly connected to a threaded rod 3211 that passes through the clamping block 320 and the positioning block 311. The threaded rod 3211 has an internal thread at the connection point with the positioning block 311 and the clamping block 320. The top of the positioning block 311 and the clamping block 320 are provided with a prismatic clamping groove 330 facing downwards. The probe can be placed in the clamping groove 330. The prismatic clamping groove 330 can better contact the object being measured and generate force, so that the clamping block 320 and the positioning block 311 can fully contact and fix it. Then, by moving the threaded rod 3211 in the direction of the positioning block 311, the clamping block 320 moves in the same direction, which can further keep the clamping block 320 and the positioning block 311 clamping the probe tightly and prevent the probe from falling.
