Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to an adjustable coupling centering auxiliary device. Background Art

[0002] In the electric power, metallurgy, chemical industry and other industries, water pumps and fans are widely used. Most water pumps and fans are driven by electric motors. The motor and water pump are connected by couplings. The coupling needs to be centered when installed to ensure a smooth connection between the motor and the water pump, reduce equipment vibration, and increase the life of the motor and water pump bearings. Centering the coupling is a highly precise technical work with an accuracy of 0.01mm. Therefore, in addition to the high requirements on the accuracy of the dial indicator used and the skills of the technician, the reliability of the tool used to install the dial indicator is also very high.

[0003] At present, the most widely used auxiliary tool for installing dial indicators in coupling centering is the magnetic base, which is adsorbed on the coupling by magnets. The fixation is unreliable, the adjustment length is limited, and the plastic fixing clip is easy to crack and damage, so it can only be used for smaller pump units. For large pump units, since the coupling diameter and spacing are different, the dedicated centering tools are not universal, cumbersome to use, and the accuracy is not high.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes an adjustable coupling centering auxiliary device to overcome the above technical problems existing in the existing related technology.

[0008] Furthermore, in order to enable the adjustable coupling centering auxiliary device to be fixed on any coupling of different diameters, and to be fixed in the coupling bolt hole using the chassis fixing bolts, so as to be firmly fixed and ensure stability during the centering process, a plurality of slots matching with the chassis fixing bolts are provided on the side wall of the fixed chassis, and the cross-section between the plurality of slots is in the shape of a cross.

[0009] Furthermore, in order to achieve position adjustment of the dial indicator, so as to assist in centering couplings with different diameters, and through the cooperative drive of the threaded portion, not only the adjustment accuracy is higher, but also the two adjusting rods can be moved at the same time, thereby ensuring the symmetrical movement of the adjusting rods, thereby improving the applicability of the adjustable coupling centering auxiliary device, the combined meter frame adjustment mechanism includes a fixed rod connected to the combined telescopic connecting rod, and the bottom and top ends of the fixed rod are both provided with adjusting rods, the top of one of the fixed rods is provided with a cross bar, and the ends of the fixed rod and the cross bar are both interspersed with dial indicators; partitions are symmetrically arranged in the middle of the fixed rod, and driven rods passing through the partitions are symmetrically arranged in the middle of the fixed rod, and bevel gears 1 are sleeved on the outside of the adjacent ends of the two groups of driven rods; a driving rod is penetrated in the middle of the side wall of the fixed rod, and a bevel gear 2 meshing with bevel gear 1 is sleeved on the outside of one end of the driving rod and located inside the fixed rod, and the dial indicator is connected to the fixed rod and the cross bar by fastening bolts.

[0010] Furthermore, in order to enable the adjusting rod to move under the drive of the driven rod, the cross-section of the adjusting rod is a square structure, and a threaded hole is provided at the end of the adjusting rod close to the driving rod; a thread matching the threaded hole is provided on the outer side of the circle of the driven rod away from the partition.

[0011] Furthermore, in order to achieve length adjustment of the combined telescopic connecting rod, the telescopic combination between the inner and outer steel pipes is used so that the combined telescopic connecting rod can be freely extended and retracted during the adjustment process and can adapt to different measurement requirements. The combined telescopic connecting rod is composed of several steel pipes with successively decreasing diameters, and the steel pipes are fixed by connecting rod fixing bolts.

It can be widely used in industries with more water pumps and fans, such as electric power, metallurgy, and chemical industry.

[0014] 2. By setting a fixed chassis, the adjustable coupling centering auxiliary device can be fixed on any coupling of different diameters, and the chassis fixing bolts are used to fix it in the coupling bolt holes, so that it is firmly fixed and the stability during the centering process is ensured.

[0015] 3. By setting up a combined meter frame adjustment mechanism, the position adjustment of the dial indicator is realized, so that the centering assistance can be performed on couplings with different diameters.
