Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coupling installation technology, specifically relating to a coupling alignment tooling. Background Technology
[0002] As a critical connecting component in mechanical transmission, the installation and alignment accuracy of couplings directly affects the smoothness of equipment operation. Traditional alignment methods require dial indicators to be installed simultaneously in the radial and axial directions of the coupling, which necessitates sufficient operating space on both sides of the coupling. However, in many equipment structures, such as... Figure 1 As shown, it includes a drive motor 12, a coupling 11, and a driven device 13. The axial space between the coupling 11 and the driven device 13 is extremely narrow, making it impossible to install or adjust conventional dial indicator holders, especially for axial dial indicators. Therefore, there is an urgent need for a special tooling that can accurately install dual indicators in such a confined space. Utility Model Content
[0003] This utility model addresses the shortcomings of the prior art by providing a coupling alignment fixture to solve the problem that the limited space between the coupling and the driven device makes it impossible to install an axial dial indicator.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A coupling alignment fixture includes a radial rod, an axial rod, a first dial indicator assembly, a second dial indicator assembly, and a fixed base for connecting the coupling. The radial rod is connected to the fixed base and has a radial groove extending along its length. The axial rod is slidably connected to the radial groove and fixed by a first locking member. The axial rod has an axial groove perpendicular to the radial groove. The first and second dial indicator assemblies are both slidably connected to the axial groove and fixed by a second locking member. A radial dial indicator is mounted on the first dial indicator assembly, and an axial dial indicator is mounted on the second dial indicator assembly.
[0005] Preferably, the fixing base includes a first clamping member and a second clamping member disposed opposite to each other. The first clamping member and the second clamping member are provided with slots for accommodating the coupling on their opposite inner sides. The first clamping member and the second clamping member are locked and fixed by clamping screws.
[0006] Preferably, the first clamping member is provided with a countersunk hole for accommodating a clamping screw, and the clamping screw passes through the countersunk hole and is threadedly connected to a threaded hole provided on the second clamping member.
[0007] Preferably, the slot has a gradually decreasing inner diameter from its opening side to the bottom side.
[0008] Preferably, the vertical cross-sectional shape of the slot is V-shaped or isosceles trapezoidal.
[0009] Preferably, both the first locking member and the second locking member are nuts, and the nuts are threadedly connected to the frame assembly.
[0010] Preferably, the first and second watch holder assemblies have the same structure, each including a fixing rod, a locking block and a locking screw. One end of the fixing rod is connected to the locking block, the locking block is provided with a clamping part, and the clamping part is threaded with a locking screw for clamping and fixing.
[0011] Preferably, the clamping part includes a mounting hole and an opening on the locking block. The opening is located on the side of the locking block away from the fixing rod and communicates with the mounting hole. The locking screw passes through the opening and is threadedly connected to the locking block to adjust the size of the opening.
[0012] Preferably, the second dial indicator assembly is provided with a third dial indicator assembly having the same structure, and the axial dial indicator is mounted on the third dial indicator assembly.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) This utility model installs the fixed base between the coupling and the driven device, and installs the axial dial indicator on the side of the drive motor where there is ample space, which fundamentally solves the problem that the axial dial indicator cannot be installed due to the narrow space between the coupling and the driven device in the prior art. (2) The two dial indicators of this utility model achieve axial position adjustment by sharing an axial rod and being in the axial groove. By adjusting the radial position of the axial rod in the radial groove, it can adapt to the use requirements of couplings of different sizes. (3) The fixing seat of this utility model adopts an isosceles trapezoidal slot design, which is stable and compact, avoids interference with other components, and improves the alignment efficiency and accuracy.

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0019] like Figure 2 and Figure 3As shown, a coupling alignment fixture includes a radial rod 1, an axial rod 2, a first dial indicator assembly 3a, a second dial indicator assembly 3b, and a fixed base for connecting the coupling. The radial rod is connected to the fixed base and has a radial groove 101 extending along its length. The axial rod is slidably connected to the radial groove and fixed by a first locking member. The position of the axial rod within the radial groove is freely adjustable. The axial rod has an axial groove 201 perpendicular to the radial groove. Both the first and second dial indicator assemblies are slidably connected to the axial groove and fixed by a second locking member. The positions of the first and second dial indicator assemblies within the axial groove are freely adjustable. In this embodiment, both the first and second locking members are nuts 10, which are threadedly connected to the dial indicator assemblies for easy operation. A radial dial indicator 4 is mounted on the first dial indicator assembly, with its probe pointing towards the radial measuring surface of the coupling. An axial dial indicator 5 is mounted on the second dial indicator assembly, with its probe pointing towards the axial measuring surface of the coupling.
[0020] Combination Figures 2 to 4 As shown, the fixing base includes a first clamping member 6 and a second clamping member 7 arranged opposite to each other. The inner sides of the first and second clamping members are provided with slots 8 for accommodating couplings. The slots have a gradually decreasing inner diameter from the opening side to the bottom side, suitable for various coupling specifications. Their vertical cross-sectional shape is V-shaped or isosceles trapezoidal; in this embodiment, an isosceles trapezoidal shape is used. The first and second clamping members are locked together by clamping screws 9. The first clamping member has a countersunk hole 601 for accommodating the clamping screw. The clamping screw passes through the countersunk hole and is threadedly connected to a threaded hole 701 on the second clamping member 7. The clamping screw is concealed, with its head housed inside the countersunk hole to avoid interference with other components.
[0021] like Figure 1 and Figure 2 As shown, the first and second watch components have the same structure, combined with Figure 3As shown, both frame components include a fixing rod 301, a locking block 302, and a locking screw 303. One end of the fixing rod is connected to the locking block, which has a clamping part. The clamping part is threaded with a locking screw for clamping and fixing. The clamping part includes a mounting hole 304 and an opening 305 on the locking block. The opening is located on the side of the locking block away from the fixing rod and communicates with the mounting hole. The locking screw passes through the opening and is threaded to the locking block to adjust the size of the opening. By turning the locking screw, the clamped part in the mounting hole can be locked and fixed. The second dial indicator assembly has a third dial indicator assembly 3c with the same structure. The axial dial indicator is mounted on the third dial indicator assembly. The fixing rod of the third dial indicator assembly is clamped in the mounting hole of the locking block of the second dial indicator assembly, so that the mounting directions of the axial dial indicator and the radial dial indicator are perpendicular to each other, thereby realizing the simultaneous measurement of the coupling in both the axial and radial directions. When installing the radial and axial dial indicators, their external bushings are clamped and fixed in the mounting holes of each dial indicator assembly.
[0022] The method of using this utility model is as follows: (1) Based on the actual situation, the space between the two ends of the coupling 11 and the drive motor 12 and the driven device 13 is selected. The side with the smaller space is used to install the fixing seat, while the side with the larger space is used to install the axial dial indicator. When installing the fixing seat, the first clamping member 6 and the second clamping member 7 are placed on both sides of the coupling 11 body (coupling cam shaft), and the clamping screws 9 are turned to lock and fix it.
[0023] (2) Install the third dial indicator assembly 3c, which is equipped with the axial dial indicator 5, onto the second dial indicator assembly 3b. Then, install the second dial indicator assembly 3b and the first dial indicator assembly 3a into the axial groove 201 of the axial rod 2, adjust their positions in the axial groove 201 according to actual needs, and adjust the position of the axial rod 2 in the radial groove 101. Tighten the first locking piece and the second locking piece to achieve locking and fixing. At this time, the probe of the radial dial indicator 4 is aligned with the radial measuring surface (outer circle) of the coupling 11, while the probe of the axial dial indicator 5 is aligned with the axial measuring surface (end face) between the coupling 11 and the drive motor 12.
[0024] (3) The position of the radial dial indicator 4 is finely adjusted by the locking screw 303 on the first dial indicator assembly 3a, and the position of the axial dial indicator 5 is finely adjusted by the locking screw 303 on the second dial indicator assembly 3b and the third dial indicator assembly 3c, and a reasonable preload is reserved.
[0025] (4) Drive the coupling 11 to rotate, record the readings of the radial dial indicator 4 and the axial dial indicator at different angular positions of 5, and calculate the centering deviation accordingly.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
