Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to an intelligent device for measuring the concentricity of pumps and motors. Background Technology

[0002] Measuring and adjusting the concentricity of pumps and motors is an important aspect of pump maintenance. Currently, commonly used methods for measuring and adjusting pump concentricity include the feeler gauge method, the dial indicator method (dial stand method), laser alignment instruments, and laser measurement systems with AI algorithms. The feeler gauge method has low accuracy (error ≥ 0.05mm) and relies heavily on operator experience. Laser measurement systems typically cost tens of thousands of yuan or more, offering an accuracy of ±0.001mm, which is higher than traditional dial indicator measuring devices, but requires strict operating conditions. Dial indicator measurement accuracy is ±0.01mm and is typically used for calibrating industrial pumps with high precision requirements.

[0037] 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.

[0038] Example 1:

[0039] Please see Figure 1 This utility model provides an intelligent device for measuring the concentricity of a pump and motor, comprising a first support 3 and a second support 4. The first support 3 includes a first vertical part 31, and a first upper horizontal part 32 is provided at the upper end of the first vertical part 31. The second support 4 includes a second vertical part 41. A vertical first dial indicator 5 is provided on the first upper horizontal part 32, and the dial indicator 5 contacts the upper end face of the second vertical part 41. A horizontal second dial indicator 6 is provided on the second vertical part 41, and the dial indicator 6 contacts the front end face of the first vertical part 31. The first vertical part 31 and the second vertical part 41 are arranged opposite each other and their opposite faces are parallel. The lower end of the first vertical part 31 is connected to a first base 1, and the lower end of the second vertical part 41 is connected to a second base 2. The first base 1 and the second base 2 are used for couplings.

[0040] The upper surface of the second vertical part 41 and the front surface of the first vertical part 31 are smooth surfaces, which improves the detection accuracy.

[0041] Specifically, the lower end of the first vertical part 31 is provided with a first lower horizontal part 33 opposite to the first upper horizontal part 32. The first lower horizontal part 33 is connected to the first base 1, so that the first support 3 has a "Z" structure with the middle section being vertical. The lower end of the second vertical part 41 is provided with a second lower horizontal part 42, so that the second support 4 has an "L" structure. The second lower horizontal part 42 is connected to the second base 2. The first upper horizontal part 32, the first lower horizontal part 33, and the second lower horizontal part 42 are located on the same straight line.

[0042] Specifically, the shaft reference hole is a blind hole, and the shaft reference holes of the first base 1 and the second base 2 are arranged back to back. When not in use, a protective plug is placed in the shaft reference hole.

[0043] Specifically, the first upper horizontal portion 32 is provided with a vertical first mounting hole, which is located directly above the second vertical portion. The first dial indicator 5 is inserted into the first mounting hole. The first upper horizontal portion 32 is provided with a first threaded hole that is radially connected to the first mounting hole. The first threaded hole is internally threaded with a first fixing screw 71 to fix the first dial indicator 5. The second vertical portion 41 is provided with a horizontal second mounting hole, which is directly opposite the first vertical portion 31. The second dial indicator 6 is inserted into the second mounting hole. The second vertical portion 41 is provided with a second threaded hole that is radially connected to the second mounting hole. The second threaded hole is internally threaded with a second fixing screw 72 to fix the second dial indicator 6.

[0044] The first dial gauge 5 and the second dial gauge 6 are both digital dial gauges, integrating a data acquisition module and a Bluetooth transmission module. They can collect the measurement differences in the axial (up, down, left, right) and radial (up, down, left, right) directions in real time. The first dial gauge 5 and the second dial gauge 6 are existing technologies, and those skilled in the art are clear about their structure, so they will not be described in detail here.

[0045] Furthermore, the first base 1 and the second base 2 are magnetic switch bases. The lower end surfaces of the first base 1 and the second base 2 are provided with trapezoidal grooves that cooperate with the coupling. The upper end surfaces of the first base 1 and the second base 2 are both smooth. The lower end surfaces of the first lower horizontal part 33 and the second lower horizontal part 42 are both smooth. The upper end surface of the first base 1 of the first lower horizontal part 33 is magnetically engaged.

[0046] By setting up a first base 1 and a second base 2, as well as a first bracket 3 and a second bracket 4 of corresponding shapes, two sets of dial indicators can be quickly installed. The dial indicator 5 makes radial dialing by contacting the top plane of the second bracket 4, and the dial indicator 6 makes axial dialing by contacting the vertical side wall of the first bracket 3. This measuring tool can improve the installation efficiency during measurement, save time, and has a simple structure and strong stability. The two sets of dial indicators are in the same position, which makes it convenient to read the values ​​during measurement.

[0047] Specifically, positioning grooves are provided on the opposite surfaces of the first base 1 and the second base 2, and positioning blocks are sandwiched between the positioning grooves of the first base 1 and the second base 2 to facilitate the rapid positioning of the first base 1 and the second base 2.

[0048] Furthermore, it also includes a linear motion locking mechanism, wherein the first base 1 and the second base 2 are both bases, and the first lower horizontal part 33 and the second lower horizontal part 42 are both lower horizontal parts, and the bases and lower horizontal parts are connected by the linear motion locking mechanism.

[0049] Specifically, the linear movement locking mechanism includes a square groove 10 and a sliding groove 12. The lower horizontal part is provided with a square groove 10 that runs vertically through the base. The upper end face of the base is provided with a sliding groove 12 that runs axially through the shaft reference hole. The lower horizontal part is slidably disposed in the sliding groove 12. The sliding groove 12 is provided with a clamping threaded hole within the projection of the square groove 10. The lower horizontal part is provided with a clamping bolt 11 in the square groove 10. The clamping bolt 11 is threadedly connected to the clamping threaded hole. The clamping bolt 11 can clamp the lower horizontal part.

[0050] By setting the slide groove 12, the direction of movement of the first support 3 and the second support 4 can be restricted, ensuring that the first support 3 and the second support 4 can be parallel when adjusting their positions.

[0051] By setting the square groove 10 and the clamping bolt 11, the first bracket 3 and the second bracket 4 can be moved relatively far apart or relatively close together. After the first bracket 3 and the second bracket 4 are moved to the appropriate position, the clamping bolt 11 is used to lock the first bracket 3 and the second bracket 4, which facilitates the quick adjustment of the distance between the first bracket 3 and the second bracket 4 in complex measurement environments and improves measurement efficiency.

[0052] How to use this embodiment:

[0053] Activate the magnetism of the first base 1 and the second base 2, magnetically engage the first base 1 and the second base 2 with the coupling, clamp the positioning block between the positioning grooves of the first base 1 and the second base 2 to align the first base 1 and the second base 2, adjust the position of the first dial indicator 5 by the first fixing screw 71, adjust the position of the second dial indicator 6 by the second fixing screw 72, and adjust the position of the first bracket 3 and the second bracket 4 by the linear movement locking mechanism, so that the dial indicator head of the first dial indicator 5 contacts the upper end face of the second vertical part 41, and the dial indicator head of the second dial indicator 6 contacts the front end face of the first vertical part 31;

[0054] Rotate the coupling and collect four sets of differences from the axial second dial indicator 6 and the radial first dial indicator 5: upper, lower, left, and right.

[0055] Both dial gauge 5 and dial gauge 6 are digital dial gauges, which can export data without manual recording. After obtaining the deviation data, the thickness of the front and rear gaskets of the motor base is adjusted on-site according to the existing pump shim adjustment process.

[0056] Example 2:

[0057] Based on Example 1, such as Figure 2 As shown, in this embodiment, an embedded groove 16 is provided on the upper end face of the first base 1. The embedded groove 16 partially overlaps with the sliding groove 12 on the first base 1. A gear 14 is rotatably arranged in the embedded groove 16. A toothed plate 13 is provided on the end face of the first lower horizontal part 33 near the gear 14. The toothed plate 13 meshes with the gear 14. A knob 15 is connected to the top of the gear 14 for rotating the gear 14.

[0058] Rotating gear 14 can drive the toothed plate 13 to move slightly laterally, adjusting the position of the first support 3. The short-distance movement of the first support 3 presses the head of the second dial indicator 6 until the dial indicator 6 displays "0". Then tighten the clamping bolt 11 to calibrate the second dial indicator 6 to "0" for easy calculation of values ​​during measurement, improving measurement efficiency. A knob 15 is provided on the top of gear 14 for easy operation. An inner groove 16 is provided and the gear 14 is installed inside the inner groove 16 to prevent touching the teeth of gear 14 during operation, improving the safety of the entire tool.

[0059] Example 3:

[0060] Based on Example 1, such as Figure 3 As shown, in this embodiment, the first base 1 and the second base 2 are connected by a positioning mechanism.

[0061] The positioning mechanism includes a positioning plate 8 and a fixing bolt 9. A positioning threaded hole is provided on one side end face of the first base 1 or the second base 2. The fixing bolt 9 is internally threaded into the positioning threaded hole and presses the positioning plate 8 onto the side end face.

[0062] Specifically, the positioning plate 8 is a rectangular plate with four chamfered corners.

[0063] By installing a positioning plate 8 on the side wall of the first base 1 or the second base 2, the first base 1 and the second base 2 can be quickly aligned during installation, preventing inaccurate measurements caused by misalignment of the dial indicator head with the measuring point due to misalignment of the first base 1 and the second base 2.

[0064] Example 4:

[0065] Based on Example 1, such as Figure 4 As shown, in this embodiment, a threaded sleeve 17 is fixedly installed in the first mounting hole of the first upper horizontal part 32. The inner wall of the threaded sleeve 17 is threadedly connected to a threaded bushing 18. The inner wall of the threaded bushing 18 is inserted and fitted with the first dial indicator 5, so that the lower end of the dial indicator 5 extends downward through the mounting hole and contacts the upper end face of the second vertical part 41 of the second bracket 4.

[0066] By rotating the threaded bushing 18, the height of the threaded bushing 18 can be changed by a short distance, thereby achieving fine adjustment of the position of the dial indicator 5 in the vertical direction. Fine adjustment of the position of the dial indicator 5 until the dial indicator 5 displays "0" mark, and then tightening the dial indicator fixing screw 7 to fix the dial indicator 5. Calibrating the dial indicator 5 to "0" mark also facilitates the calculation of values ​​during the measurement process, improving measurement efficiency.
