Description

Technical Field

[0001] This application belongs to the field of equipment installation technology, and in particular relates to a dial indicator holder for coupling alignment. Background Technology

[0002] The cooling tower fan shaft seal needs to be repaired due to oil leakage. After the repair, the fan coupling and motor coupling need to be readjusted for concentricity during the installation process. If the fan concentricity error exceeds the specification value, it will cause the fan to vibrate during operation and may even cause bearing wear. Therefore, ensuring the concentricity of the cooling tower fan coupling and motor coupling is crucial.

[0003] In the existing technology, the dial indicator holder used for concentricity adjustment is fixed by magnetic attraction from a magnetic base. However, due to the uneven surface of the coupling, the contact area between the coupling and the dial indicator holder is too small, resulting in an unstable holder and failure to achieve concentricity calibration. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, this application provides a dial indicator holder for coupling alignment, which can be easily and firmly fixed on the coupling, and the position of the dial indicator is adjustable.

[0005] To achieve the above objectives, the technical solution provided in this application is as follows: This application provides a dial indicator holder for coupling alignment, including a fixed rod and an adjusting rod. The fixed rod is adjustablely fixed to the adjusting rod via a connector. A nut is fixed on the fixed rod, which is used to lock the dial indicator to a threaded hole on the coupling via a screw. The dial indicator is mounted on the adjusting rod.

[0006] Optionally, the connector includes a connecting block, an adjusting block, and a locking nut. The connecting block can slide and rotate along the fixed rod. The adjusting block is rotatably connected to the connecting block. The adjusting rod can slide and rotate along the adjusting block. The locking nut is used to lock the adjusting rod, adjusting block, connecting block, and fixed rod together. The dial indicator is mounted on the adjusting rod.

[0007] Optionally, the connecting block includes two clamping blocks with a groove between them, and the fixing rod slides along the groove; the connecting block has a sliding groove along its axial direction, and the adjusting rod slides and connects to the sliding groove; the two clamping blocks have through holes, the connecting block passes through the through holes, and one end of the connecting block is threadedly connected to the locking nut. The locking nut can lock the adjusting rod by rotating along the connecting block, and at the same time, the two clamping blocks lock the fixing rod.

[0008] Optionally, the adjusting rod is located on the side of the connecting block opposite to the locking nut.

[0009] Optionally, when the two clamping blocks are fitted together, the distance between the inner walls of the slots of the two clamping blocks is not greater than the diameter of the fixing rod.

[0010] Optionally, the adjusting rod is provided with a clamp for clamping the dial indicator.

[0011] Optionally, the clamp includes a locking buckle and a clamping plate fixed on the adjusting rod. The clamping plate is provided with a clamping groove for mounting a dial indicator. The dial indicator can be locked in the clamping groove by clamping the clamping plate with the locking buckle.

[0012] Optionally, the locking nut is provided with a through hole, and a rod is inserted into the through hole.

[0013] Compared with the prior art, this application has at least the following beneficial effects: This application achieves a secure fixation of the dial indicator by setting a nut at the bottom of the fixed rod and tightening it onto the coupling with screws. In this application, the connecting block can slide and rotate along the fixed rod, the adjusting block is rotatably connected to the connecting block, and the adjusting rod can slide and rotate along the adjusting block. This facilitates adjustment of the height, extension length, and angle of the adjusting rod and the dial indicator, making position adjustment during use easier.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0017] Example 1

[0018] like Figure 1As shown, a dial indicator holder for coupling alignment includes a fixed rod 1 and an adjusting rod 2. The fixed rod 1 is adjustablely fixed to the adjusting rod 2 via a connector. A nut 11 is fixed on the fixed rod 1, and the nut 11 is locked to the threaded hole on the coupling by a screw 12. The dial indicator is mounted on the adjusting rod 2.

[0019] The dial indicator can be securely fixed by setting a nut 11 at the bottom of the fixed rod 1 and tightening it onto the coupling with a screw 12. The fixed rod 1 is adjustablely fixed to the adjusting rod 2 via a connector, which facilitates the adjustment of the height, extension length, and angle of the adjusting rod 2 and the dial indicator, making it convenient for position adjustment during use.

[0020] Example 2

[0021] The difference between this embodiment and embodiment 1 is that the connecting component includes a connecting block, an adjusting block 4, and a locking nut 5. The connecting block can slide and rotate along the fixed rod 1. The adjusting block 4 is rotatably connected to the connecting block. The adjusting rod 2 can slide and rotate along the adjusting block 4. The locking nut 5 is used to lock the adjusting rod 2, the adjusting block 4, the connecting block, and the fixed rod 1 together. The dial indicator is installed on the adjusting rod 2.

[0022] In this embodiment, the connecting block includes two clamping blocks 3, with a groove between them, and the fixing rod 1 slides along the groove. The connecting block has a sliding groove along its axial direction, and the adjusting rod 2 slides into the groove. The two clamping blocks 3 have through holes, through which the connecting block passes, with one end threadedly connected to a locking nut 5. Rotating the locking nut 5 along the connecting block locks the adjusting rod 2 and simultaneously locks the fixing rod 1 in place. The adjusting rod 2 is located on the side of the connecting block opposite to the locking nut 5.

[0023] During use, the connecting block can be slid along the fixed rod 1 to adjust its height, the adjusting block 4 can be rotated along the connecting block to adjust its angle, and the adjusting rod 2 can be slid along the slide groove to adjust its extension length. This allows for adjustment of the height, extension length, and angle of the adjusting rod 2 and the dial indicator, thus achieving dial indicator position adjustment. When fixing is required, tighten the locking nut 5 towards the adjusting rod 2. Under the pressure of the clamping block 3, the adjusting rod 2 is fixed in the slide groove between the clamping block 3 and the adjusting block 4. Simultaneously, as the locking nut 5 is tightened, the distance between the two clamping blocks 3 decreases, and the distance between the two slots decreases, thus fixing the fixed rod 1 to the connecting block.

[0024] When the two clamping blocks 3 are in contact, the distance between the inner walls of the slots of the two clamping blocks 3 is not greater than the diameter of the fixing rod 1, so as to facilitate the distance between the slots of the two clamping blocks 3 and to clamp the fixing rod 1.

[0025] In this embodiment, the adjusting rod 2 is equipped with a clamp, which includes a locking buckle 7 and a clamping plate 6 fixed to the adjusting rod 2. The clamping plate 6 has a clamping groove 61, and the dial indicator passes through the clamping groove 61. The dial indicator can be locked in the clamping groove 61 by clamping the clamping plate 6 with the locking buckle 7. The locking buckle 7 is clamped by adjusting the inner diameter of the clamping groove 61. In this embodiment, the locking buckle 7 adopts a bolt and nut combination.

[0026] The locking nut 5 has a through hole, into which a rod is inserted. The rod facilitates tightening or loosening of the locking nut 5, making it easy to operate.

[0027] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
