Abstract
Description
Technical Field
[0001] The utility model relates to a device for placing a dial indicator when aligning a coupling, and belongs to the technical field of equipment maintenance tools. Background Art
[0002] In the work of equipment inspection and maintenance, coupling alignment is a very common and rigorous task. Once the coupling alignment has a large error, it will inevitably cause equipment vibration and noise, thereby affecting the service life of the equipment. The resulting equipment accidents will not only directly affect the normal production order of industrial enterprises, but also cause unnecessary economic losses to industrial enterprises. However, in the alignment of couplings, it is often encountered that the rotating working shaft is thin or the space is small, resulting in the situation that the dial indicator assembly cannot be adsorbed or installed easily. The base is not firmly adsorbed, resulting in the dial indicator assembly being not stable and firm enough, resulting in alignment errors, which greatly affects the accuracy of the coupling alignment work, not only affecting the accuracy of the alignment precision but also greatly reducing the labor efficiency. Therefore, it is very necessary to design and manufacture a maintenance device that is convenient for coupling alignment, improve the accuracy of the dial indicator alignment, and improve the maintenance efficiency of the operators. Utility Model Content
[0003] The technical problem to be solved by the present invention is to provide a device for facilitating the alignment of a coupling with a dial indicator. This device can install a dial indicator assembly in a narrow space of a rotating shaft, thereby facilitating the alignment of the coupling, improving the stability of the fixation of the dial indicator assembly, enhancing the accuracy of the alignment work, improving the work efficiency of personnel, and reducing manual labor efficiency.
[0004] The technical solution to the above technical problems is:
[0005] The two ends of the stud bolt are respectively locked and fixed by locking nuts. The support plate is a rectangular plate. The two support plates are respectively connected to the raised outer sides of the arc plates of the two splints. The support plate is vertically welded to the arc vertices of the arc plates. The bases of the two dial indicator assemblies are respectively adsorbed on the plate surfaces of the two support plates.
[0006] The above-mentioned device for aligning the coupling with a convenient dial indicator, the distance from the arc vertex of the arc plate of the splint to the plane of the rectangular plate surface of the splint is smaller than the radius of the clamped rotating shaft, the relative flat plates at both ends of the two splints are parallel to each other, there is a gap between the relative flat plates of the two splints, and the plate surfaces of the support plates on the outside of the two splints are parallel and on a straight line.
[0007] The beneficial effects of the utility model are:
[0008] The two clamping plates of the utility model are clamped on both sides of the rotating shaft, and the stud bolts and locking nuts fix the two clamping plates to the rotating shaft; the distance between the arc vertices of the arc plates of the two clamping plates is smaller than the diameter of the rotating shaft, so that there is a gap between the relative flat plates of the two clamping plates, so that the two clamping plates can clamp the rotating shaft; the two supporting plates are parallel and on a straight line, and the bases of the two dial indicator assemblies are respectively adsorbed on the two supporting plates, so that the coupling can be accurately aligned.
[0009] The utility model has a simple structure and is easy to use. The dial indicator assembly can be installed in a narrow space of the rotating shaft, which facilitates the alignment of the coupling, improves the stability of the fixation of the dial indicator assembly, enhances the accuracy of alignment, improves the work efficiency of personnel, and reduces manual labor efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a structural diagram of the utility model;
[0011] Figure 2 is a side view of the splint.
[0012] The markings in the figure are as follows: clamping plate 1, stud bolt 2, locking nut 3, supporting plate 4, arc plate 5, flat plate 6, connecting through hole 7, dial indicator assembly 8. DETAILED DESCRIPTION
[0013] The utility model is composed of a clamping plate 1, a stud bolt 2, a locking nut 3 and a supporting plate 4.
[0014] The figure shows that the clamping plate 1 is a rectangular plate with a raised arc plate 5 in the middle and flat plates 6 at both ends. The arc of the arc plate 5 of the clamping plate 1 matches the circumference of the clamped rotating shaft, and the distance from the arc vertex of the arc plate 5 to the plane of the rectangular plate surface of the clamping plate 1 is less than the radius of the clamped rotating shaft.
[0015] With such a structure of the clamping plate 1, on the one hand, the arcuate plate 5 matches the clamped rotating shaft, so that the arcuate plate 5 can be close to the rotating shaft, making it easier to clamp the rotating shaft; on the other hand, since the length of the arcuate plate 5 is smaller than the semicircle of the rotating shaft, when the two clamping plates 1 clamp the rotating shaft from both sides of the rotating shaft, there is a gap between the relative flat plates 6 of the two clamping plates 1, and the rotating shaft can be clamped by the stud bolts 2.
[0016] As shown in the figure, there are connecting holes 7 on the flat plates 6 at both ends of the splint 1, and the two splints 1 are respectively located on both sides of the clamped rotating shaft. The connecting holes 7 of the flat plates 6 at both ends of the two splints 1 are opposite to each other, and two stud bolts 2 are respectively passed through the connecting holes 7 opposite to each other on the flat plates 6 at both ends of the two splints 1, and the two ends of the stud bolts 2 are respectively locked and fixed by locking nuts 3.
[0017] As shown in the figure, the support plate 4 is a rectangular plate. The two support plates 4 are respectively connected to the raised outer sides of the raised arc plates 5 of the two splints 1. The support plates 4 are vertically welded to the vertices of the raised arc plates 5. The plate surfaces of the support plates 4 on the outer sides of the two splints 1 are parallel and on a straight line.
[0018] The figure shows that the bases of the two dial indicator assemblies 8 are respectively adsorbed onto the surfaces of the two support plates 4. The design dimensions of the support plates 4 meet the requirements for the adsorption installation of the dial indicator assemblies 8. The design dimensions of the support plates 4 are slightly larger than the base dimensions of the dial indicator assemblies 8, which are used to firmly adsorb and install the dial indicator assemblies 8 and accurately align the coupling.
[0019] The arc plate 5 and the flat plate 7 of the clamping plate 1 of the present invention are formed from a single piece of steel plate. The arc of the arc plate 5 can be formed by die stamping or by forging after the clamping plate 1 is heated red. Using a single piece of steel plate to form the clamping plate 1 ensures the integrity and firmness of the clamping plate 1 and ensures that the support plate 4 remains straight after welding. When manufacturing the clamping plate 1, the arc plates 5 can be manufactured with different arcs according to the shaft diameter of the rotating shaft of different equipment to accommodate the alignment of couplings of different rotating shafts.
[0020] The method of using the utility model is as follows:
[0021] Place the two splints 1 on the left and right symmetrical sides of the equipment shaft diameter, and the arc plates 5 of the two splints 1 are respectively pressed against the circumferential surface of the equipment shaft diameter. Adjust the connecting holes 7 of the flat plates 6 at both ends of the two splints 1 to be opposite to each other, take two stud bolts 2 and pass them through the relative connecting holes 7 of the flat plates 6 at both ends of the two splints 1, use a wrench to tighten the four locking nuts 3, and firmly adsorb and install the dial indicator assembly 8 on the left and right symmetrical support plates 4 according to the alignment requirements of the equipment opening and coaxiality. After verifying that there is no error in the dial indicator assembly 8, start the normal alignment operation.
[0022] An embodiment of the present invention is as follows:
[0023] The thickness of the clamping plate 1 is 8 mm, the width is 35 mm, the arc radius of the arc plate 5 is 80 mm, the arc length of the arc plate 5 is 200 mm, the length of the flat plate 6 is 60 mm, and the diameter of the connecting hole 7 is 18 mm;
[0024] The diameter of the stud bolt 2 is 16 mm and the length is 180 mm;
[0025] The supporting plate 4 has a length of 80 mm, a width of 60 mm and a thickness of 6 mm.
