Description

Technical Field

[0001] This utility model belongs to the field of shaft curvature measurement technology, and specifically relates to a measuring device for automatically calculating shaft curvature. Background Technology

[0002] The main steps for shaft bending inspection are as follows: Place both ends of the shaft on a V-block or lathe center (ensuring the shaft can rotate freely), and adjust the position of the V-block to keep the shaft horizontal. Install a dial indicator, fix it on a magnetic base, and point the indicator vertically towards the shaft surface (usually in the middle or at the suspected bending point). Divide the shaft circumference into 8-12 equal points and mark them with numbers (e.g., 0°, 90°, 180°, 270°). Slowly rotate the shaft and record the dial indicator reading (unit: mm or μm) at each point. Repeat the measurement 2-3 times and take the average value to avoid errors. Calculate the bending degree on paper, draw a bending degree diagram, and make adjustments. Previously, without specialized tools, this could only be done by hand. Even under ideal conditions, it would take highly experienced instrument technicians more than 4 hours to complete the disassembly and assembly work, resulting in a very high time cost.

[0003] In summary, we propose to develop a device for measuring shaft curvature that utilizes a Bluetooth digital micrometer to measure, a laptop to read and record data, and automatically calculates the measurement, in order to solve the aforementioned technical problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a measuring device for automatically calculating shaft curvature, thereby solving the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a measuring device for automatically calculating shaft curvature, comprising: a placement clamp, wherein the placement clamp includes a clamp body, a clamping groove, a clamping screw, a top mounting base, and an explosion-proof notebook. The left side of the clamping body is vertically penetrated to form a clamping groove. The inner side of the clamping groove is rotatably connected to a clamping screw for synchronously driving the two sets of top mounting seats on the left and right sides to move closer or further away. The top mounting seats are arranged in a left-right symmetrical structure on the top of the clamping body. A tip is installed at one end of the tip mounting base near the center of the clamp body. The tip includes a tip body. Several micrometer assemblies are also installed above the clamp body between the two sets of tip mounting bases. The micrometer assemblies include Bluetooth micrometers.

[0006] In a preferred embodiment, a clamping slider is fixedly connected below the top mounting base. The clamping slider and the clamping groove are movably engaged with each other. The clamping screw has two sets of external threads on its outer side in a left-right structure. The clamping screw and the clamping slider are also connected in a threaded engagement structure.

[0007] In a preferred embodiment, the upper surface of the top mounting base is provided with a mounting groove, and a set of positioning posts are movably fitted at both ends of the mounting groove. A pusher is fixedly connected to the end of the positioning post away from the mounting groove.

[0008] In a preferred embodiment, a positioning spring is fixedly connected to the end of the push base away from the mounting groove, and the top also includes a set of mounting blocks, with a set of positioning holes on both the front and rear sides of the mounting blocks.

[0009] In a preferred embodiment, the mounting block and the mounting groove are movably fitted together, and the positioning pin is fitted together with the positioning hole under the action of the positioning spring. The mounting block and the top body are also configured as a rotating structure and the rotation is limited by the stud. After the mounting block is embedded into the mounting groove, the external force applied to the push seat is removed, so that the positioning spring drives the positioning pin to be embedded into the positioning hole, thus completing the installation and fixing of the top.

[0010] In a preferred embodiment, the Bluetooth micrometer establishes a data transmission connection with the explosion-proof laptop. The explosion-proof laptop has built-in measurement software. The measurement data is transmitted to the explosion-proof laptop via the Bluetooth micrometer, and the built-in measurement software performs shaft curvature analysis (the measurement software uses existing mature products and only needs to meet the requirements of this utility model, so it will not be described in detail here).

[0011] In a preferred embodiment, the rear end of the upper surface of the clamp body is provided with several sets of linearly distributed lifting grooves in the left-right direction. Each set of lifting grooves is independently rotatably connected to a set of lifting screws, and a rotating handle is fixedly connected below the lifting screws.

[0012] In a preferred embodiment, the micrometer assembly further includes a set of lifting sliders, the upper surface of which is provided with lifting screw holes, and a support is fixedly connected to the rear side of the lifting sliders; A micrometer base is fixedly connected above the support. The lifting slider and the lifting groove are movably engaged with each other. The lifting screw is threadedly connected to the lifting screw hole. According to the actual measurement requirements of the shaft to be measured, the lifting screw is rotated forward and backward by hand, and the micrometer assembly is driven to lift and adjust under the thread engagement with the micrometer assembly, thereby assisting in the measurement of shaft curvature.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are: By setting up a clamping base, micrometer assembly, and tips, the tips and tips mounting base are fixed. The tips at both ends are brought close to the shaft to be measured and clamped by the forward and reverse rotation of the clamping screw. Then, several sets of linearly set Bluetooth micrometers are used to measure the different parts of the shaft to be measured. The data is then transmitted to an explosion-proof laptop via Bluetooth micrometers for calculation, which facilitates the measurement of shaft curvature.

[0014] By setting up a mounting bracket and micrometer assembly, and according to the actual measurement requirements of the shaft to be measured, the hand-held handle is rotated forward and backward to turn the lifting screw, which, in conjunction with the threaded engagement of the micrometer assembly, drives the micrometer assembly to rise and fall, thereby assisting in the measurement of shaft curvature.

Detailed Implementation

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 As the first embodiment of this utility model: A measuring device for automatically calculating shaft curvature includes: a clamping base 100, which includes a clamping base body 101, a clamping slide 102, a clamping screw 103, a top mounting base 104, and an explosion-proof notebook 112. A clamping groove 102 is formed vertically through the left side of the clamping body 101. A clamping screw 103 is rotatably connected to the inside of the clamping groove 102 for synchronously driving the two sets of top mounting seats 104 to move closer or further away. The top mounting seats 104 are arranged in a left-right symmetrical structure on the top of the clamping body 101. A tip 300 is mounted on one end of the tip mount 104 near the center of the clamp body 101. The tip 300 includes a tip body 303. Several micrometer components 200 are also mounted on the clamp body 101 between the two sets of tip mounts 104. The micrometer components 200 include a Bluetooth micrometer 205.

[0024] A clamping slider is fixedly connected below the top mounting base 104. The clamping slider and the clamping groove 102 are movably engaged with each other. The clamping screw 103 has two sets of external threads on its outer side in a left-right structure. The clamping screw 103 and the clamping slider are also connected in a threaded engagement structure.

[0025] The top mounting base 104 has a mounting groove 105 on its upper surface. A set of positioning posts 108 are movably fitted at both ends of the mounting groove 105. A pusher 107 is fixedly connected to the end of the positioning post 108 away from the mounting groove 105.

[0026] A positioning spring 106 is fixedly connected to the end of the push base 107 away from the mounting groove 105. The top 300 also includes a set of mounting blocks 301. A set of positioning holes 302 are opened on both the front and rear sides of the mounting blocks 301.

[0027] The mounting block 301 and the mounting groove 105 are movably engaged with each other. The positioning pin 108 is engaged with the positioning hole 302 under the action of the rebound force of the positioning spring 106. The mounting block 301 and the top body 303 are also configured as a rotating structure and the rotation is limited by the stud. After the mounting block 301 is embedded in the mounting groove 105, the external force applied to the push seat 107 is removed, so that the positioning spring 106 drives the positioning pin 108 to be embedded in the positioning hole 302, thus completing the installation and fixing of the top 300.

[0028] The Bluetooth micrometer 205 establishes a data transmission connection with the explosion-proof laptop 112. The explosion-proof laptop 112 has built-in measurement software. The measurement data is transmitted to the explosion-proof laptop 112 via the Bluetooth micrometer 205, and the built-in measurement software performs shaft bending analysis (the measurement software uses existing mature products and only needs to meet the requirements of this utility model, so it will not be described in detail here).

[0029] Specifically, before measuring the shaft curvature, the operator installs two sets of centers 300, embedding the mounting block 301 into the mounting groove 105. Then, the external force applied to the push base 107 is removed, causing the positioning spring 106 to drive the positioning pin 108 into the positioning hole 302, thus completing the installation and fixing of the centers 300. The shaft to be measured is placed between the two sets of centers 300. Rotating the clamping screw 103, in conjunction with the clamping slider, causes the two sets of centers 300 to press against both ends of the shaft to be measured. Next, several sets of micrometer assemblies 200 are installed in a lateral position, allowing the Bluetooth micrometer 205 to measure the outer diameter data of different sections of the shaft to be measured. The data is then transmitted to the explosion-proof laptop 112, and the shaft curvature is analyzed by the built-in measurement software (the measurement software uses existing mature products and only needs to meet the requirements of this utility model, so it will not be described in detail here). During the measurement, the circumferential position is adjusted by the rotation structure of the center body 303, which facilitates the measurement of shaft curvature.

[0030] Please see Figures 1-2 and Figure 4 As a second embodiment of this utility model: The upper surface of the clamp body 101 has several sets of linearly distributed lifting grooves 109 on the rear end in the left and right direction. Each set of lifting grooves 109 is independently rotatably connected to a set of lifting screws 110, and a rotating handle 111 is fixedly connected below the lifting screws 110.

[0031] The micrometer assembly 200 also includes a set of lifting sliders 201. The upper surface of the lifting slider 201 is provided with a lifting screw hole 202, and a support 203 is fixedly connected to the rear side of the lifting slider 201. A micrometer base 204 is fixedly connected above the support 203. The lifting slider 201 and the lifting slide 109 are movably engaged with each other. The lifting screw 110 is threadedly connected to the lifting screw hole 202. According to the actual measurement requirements of the axis to be measured, the lifting screw 110 is rotated forward and backward by hand with the handle 111, and the micrometer assembly 200 is driven to lift and adjust under the threaded engagement with the micrometer assembly 200.

[0032] Based on the first embodiment described above, further, in the measurement of shaft curvature, according to the actual measurement requirements of the shaft to be measured, the lifting screw 110 is rotated forward and backward by hand handle 111, so that the lifting screw 110 and the lifting screw hole 202 are threadedly engaged, thereby driving the micrometer assembly 200 to be raised and lowered, so that the Bluetooth micrometer 205 is in a suitable measurement position, thereby assisting in the measurement of shaft curvature.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
