Description

Technical Field

[0001] The present application relates to the technical field of coupling alignment measurement, and in particular to a convenient alignment tool. Background Art

[0002] Coupling is a common mechanical transmission device, widely used in various mechanical equipment. The alignment of the coupling is one of the important factors affecting its normal operation. Correct alignment can ensure the transmission efficiency and service life of the coupling, while incorrect alignment will cause equipment vibration, noise and damage.

[0003] In the related technology, coupling alignment generally adopts dial indicator alignment and laser alignment instrument alignment. Although laser alignment instrument has many advantages such as simple operation, fast and accurate measurement, and concise and intuitive measurement results, it is expensive and not conducive to popularization. When aligning the coupling with a dial indicator, first ensure that the coupling is in place, use the dial indicator to measure and record, and align the coupling according to the measurement value of the dial indicator.

[0004] The problem with the related technology is that the connection and adjustment methods between the various components of the traditional alignment tool are often cumbersome, which requires operators to spend a lot of time and energy on debugging during the measurement process, seriously affecting the measurement efficiency. In addition, when fixed by a magnetic base, the adsorption force between the magnetic base and the half-coupling is difficult to control, and it is difficult to firmly connect to the half-coupling after long-term use, which will affect the measurement accuracy. Utility Model Content

[0005] In order to facilitate the flexible adjustment of various components of the centering tool, improve measurement efficiency, and improve measurement accuracy, the present application provides a convenient centering tool.

[0006] A convenient centering tool provided in this application adopts the following technical solution:

[0007] A convenient alignment tool comprises a magnetic base, a base frame and a measuring instrument, wherein the magnetic base is fixed on a first half coupling, one end of the base frame is connected to the magnetic base, and the other end extends toward a second half coupling, and the measuring instrument is fixed on the base frame, and the base frame comprises an adjustment block, a first rod body and a second rod body, wherein a first through hole and a second through hole penetrating through the surface of the adjustment block are provided, the first rod body is penetrated in the first through hole and connected to the magnetic base, the second rod body is penetrated in the second through hole and extends toward the second half coupling, and a locking assembly is arranged on the adjustment block, and the locking assembly is used for locking and loosening the first rod body and the second rod body.

[0008] By adopting the above technical solution, when the locking assembly prevents the first rod body and the second rod body from loosening, the adjustment block can slide up and down along the first rod body, and the second rod body can slide horizontally to adjust the position of the measuring instrument according to the actual size of the coupling. After the adjustment is completed, the locking assembly can fix the position of the adjustment block, the first rod body and the second rod body, which is simple to operate and improves the measurement efficiency.

[0009] Optionally, the meter frame also includes a mounting seat, which is connected to one end of the second rod body close to the half-coupling two, and a slot is formed on the mounting seat.

[0012] By adopting the above technical solution, when the locking screw is screwed into the third through-hole, the chuck approaches the first rod body inserted into the first through-hole, and finally abuts against the outer surface of the first rod body to lock the first rod body in the first through-hole. When the locking screw is screwed out, the clamping head moves away from the first rod body, so that the first rod body can be relatively displaced with the adjustment block.

[0013] Optionally, the adjusting block includes a first block and a second block, and the locking assembly also includes a locking nut arranged at an end of the locking screw away from the chuck, and one end face of the locking nut abuts against an outer surface of the second block so that when the locking screw is tightened toward the adjusting block, the locking nut can press the second block against the first block.

[0014] By adopting the above technical solution, when the locking screw is screwed into the third through hole, the locking nut can drive the second block to press against the first block to clamp the second rod in the second through hole. This structure realizes synchronous locking or anti-loosening of the first rod and the second rod, and is simple to operate and easy to adjust.

[0015] Optionally, an auxiliary fixing mechanism is fixed on the first rod body, the auxiliary fixing mechanism is located between the adjustment block and the magnetic base, the auxiliary fixing mechanism has at least two clamping ends, and at least two of the clamping ends are symmetrically distributed along the central axis of the first half coupling.

[0019] Optionally, the clamping assembly includes a clamping plate 1 and a clamping plate 2 which are cooperatively arranged on both sides of a half-coupling, and corresponding holes are opened on the clamping plate 1 and the clamping plate 2. The clamping assembly also includes a clamping screw and a clamping nut. The clamping screw is passed through the hole body, and the clamping nut is screwed to one end of the clamping screw and is located on the side of the clamping plate 2 facing away from the clamping plate 1.

[0020] By adopting the above technical solution, when the clamping nut is turned, the clamping plate 2 can be driven close to the clamping plate 1, so as to apply a clamping force to the outer edge of the half coupling 1 located between the clamping plates 1 and 2, thereby improving the fixing effect.

[0021] Optionally, the measuring instrument includes three dial indicator bodies, wherein the measuring rod contact of one of the dial indicator bodies abuts against the outer peripheral surface of the second half coupling, and the measuring rod contacts of the other two dial indicator bodies abut against the end surface of the second half coupling.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] Example 1

[0034] The present application discloses a convenient centering tool. It is particularly suitable for power equipment such as chemical pumps and compressors. Figure 1A convenient alignment tool includes a magnetic meter base 1, a meter frame 2 and a measuring instrument 3. When the above-mentioned chemical pump equipment is connected to the compressor through a half coupling 10 and a half coupling 20 with the same structure, the magnetic meter base 1 is fixed on the half coupling 10, the meter frame 2 is connected to the magnetic meter base 1 and extends to the half coupling 20, and the measuring instrument 3 is installed on the meter frame 2. A measuring rod contact 31 is provided on the measuring instrument 3, and the measuring rod contact 31 abuts against the surface of the half coupling 20. At this time, the staff rotates the half coupling 10, and the measuring instrument 3 measures the relevant deviation parameters of the half coupling 20. The staff adjusts the relative position of the equipment according to the measured data to achieve alignment.

[0035] The magnetic base 1 can be fixed on the half coupling 10 by magnetic adsorption. Its specific structure and adsorption principle belong to the prior art and will not be described in detail here.

[0036] In order to improve the accuracy and comprehensiveness of the measurement, the measuring instrument 3 preferably includes three dial gauge bodies, and the measuring rod contacts 31 of the three dial gauge bodies are respectively in contact with different parts of the half coupling 20. Specifically, the measuring rod contact 31 of one dial gauge body is in contact with the outer peripheral surface of the half coupling 20, which is used to measure the radial runout of the half coupling 20; the measuring rod contacts 31 of the other two dial gauge bodies are in contact with the end surface of the half coupling 20, which is used to measure the axial movement of the half coupling 20. Through this arrangement, the alignment of the coupling can be more comprehensively reflected, providing an accurate basis for adjusting the coupling.

[0037] The measuring rod contact 31 is made of high-hardness stainless steel, which is wear-resistant, corrosion-resistant and not easy to deform. Its specific structure is elastic contact type. Through the elastic retraction effect, the measuring rod contact 31 and the surface of the half coupling 20 generate greater pressure, thereby achieving more accurate measurement.

The locking assembly 4 includes a locking screw 41 and a chuck 42 arranged in the third through hole, and the chuck 42 is arranged at one end of the locking screw 41 close to the first through hole. When the locking screw 41 is tightened toward the adjustment block 21, the chuck 42 can lock the first rod 22 in the first through hole. Specifically, a side of the chuck 42 facing the first through hole is set as an arc-shaped locking surface. When the chuck 42 is close to the first rod 22, it can be in close contact with the outer peripheral surface of the first rod 22 to ensure the locking effect.

[0043] The locking assembly 4 also includes a locking nut 43 arranged at an end of the locking screw 41 away from the chuck 42, and one end face of the locking nut 43 abuts against the outer surface of the second block 212.
