Description

Technical Field

[0001] This utility model relates to the technical field of eccentricity measurement equipment, and in particular to a measuring fixture for measuring the eccentricity value of a coupling. Background Technology

[0002] Coupling eccentricity measurement is to detect the coaxiality deviation when two shafts are connected. It is a key step to ensure the smooth operation of the transmission system. Excessive deviation will cause vibration, noise and bearing wear, affecting the life of the equipment. The measurement should be carried out in a static or low-speed rotation state, and is divided into two steps: radial and axial.

[0003] Under normal testing conditions, existing eccentricity measuring equipment can monitor the eccentricity of couplings. However, when maintaining couplings in the drive mechanisms of switch machines and signal machines, traditional eccentricity measuring equipment is difficult to install due to its complex location, the presence of crisscrossing cables and pipes around the equipment, its complex mechanical structure, and the presence of ballast around the equipment. This makes it difficult to provide stable operating conditions for the equipment, and the equipment is easily interfered with during installation, requiring repeated adjustments to its position. As a result, the detection efficiency of couplings in the drive mechanisms of switch machines and signal machines is low when they are re-checked on-site. Utility Model Content

[0004] The purpose of this invention is to provide a measuring fixture for the eccentricity of couplings, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A measuring fixture for measuring the eccentricity of a coupling includes a base, a partition plate fixedly installed inside the base, a first adjusting screw rotatably connected to one side of the partition plate, a fixed clamping block fixedly installed on the base, a movable clamping block movably installed on the base, a base plate fixedly installed near the fixed clamping block, two first guide shafts fixedly installed on the base plate, a top plate fixedly connected to the two first guide shafts, a second adjusting screw rotatably connected to the base plate and the top plate located between the two first guide shafts, an L-shaped side rod movably connected between the first guide shafts and the second adjusting screw, an adjusting wheel movably installed inside the L-shaped side rod, a third adjusting screw threadedly connected to the adjusting wheel, second guide shafts movably installed on the L-shaped side rods located on both sides of the third adjusting screw, a carrier plate fixedly connected between the two second guide shafts, a dial indicator fixedly installed on the carrier plate, an adsorption plate fixedly installed at the bottom of the base, and a top rod movably installed inside the base near the partition plate.

[0007] As a further preferred embodiment of this utility model, the adsorption plate is provided with a positioning groove, and the adsorption plate can be positioned and installed on the rail through the positioning groove. Multiple magnetic blocks are fixedly installed at the top of the positioning groove. After the adsorption plate is installed on the rail through the positioning groove, the magnetic blocks can be used to adsorb and fix the adsorption plate on the rail, thereby completing the installation of the base.

[0008] As a further preferred embodiment of this utility model, the base is provided with an inner spiral guide hole, and a spiral guide block is fixedly installed inside the inner spiral guide hole. A spiral guide groove is provided on the outer side of the top rod. The top rod is rotatably connected to the inner spiral guide hole through the spiral guide groove. The top rod is installed in the inner spiral guide hole through the outer spiral guide groove, which enables the bottom of the spiral guide groove to be quickly moved out of the inner spiral guide hole and abut against the rail when the top rod is rotated, thereby causing the magnetic block on one side of the top of the positioning groove to disengage from the rail, thus facilitating the removal of the base from the rail.

[0009] As a further preferred embodiment of this utility model, a handwheel is fixedly installed on the top of the second adjusting screw, and the second adjusting screw is threadedly connected to one of the screw holes in the L-shaped side rod. The cooperation between the first guide shaft and the second adjusting screw enables the L-shaped side rod to move vertically, thereby adjusting the operating height of the dial indicator.

[0010] As a further preferred embodiment of this utility model, an installation groove is provided on one side of the L-shaped side rod, and a rotating groove is provided on one side of the installation groove. A limit block is fixedly installed in the installation groove, and a rotating groove is also provided on one side of the limit block. Fixed rings are fixedly installed on both sides of the adjusting wheel, and the fixed rings are rotatably installed in the corresponding rotating grooves. The adjusting wheel rotates in the installation groove and can be rotated on the third adjusting screw through the thread at the middle position of the adjusting wheel, thereby adjusting the horizontal position of the carrier plate, so that the dial indicator can be adjusted to a horizontal position.

[0011] As a further preferred embodiment of this utility model, one end of the third adjusting screw is rotatably mounted on one side of the carrier plate.

[0012] As a further preferred embodiment of this utility model, the fixed clamping block and the movable clamping block are respectively provided with V-shaped grooves on their opposite sides. Providing V-shaped grooves on the opposite sides of the fixed clamping block and the movable clamping block can facilitate the clamping of couplings of different diameters.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, a base plate, a top plate, a first guide shaft, a second adjusting screw, and an L-shaped side rod are provided on the base. The L-shaped side rod is equipped with an adjusting wheel and a third adjusting screw, which can conveniently adjust the vertical and horizontal position of the dial indicator. In conjunction with the first adjusting screw, a fixed clamping block, and a movable clamping block, couplings of different diameters can be quickly clamped and fixed. This allows the base to be positioned and installed on the rail with the help of the bottom top plate. The relatively flat rail provides an installation foundation for the entire device. The entire device is easy to carry and install, and facilitates on-site verification of coupling eccentricity. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-4As shown, the present invention provides a measuring fixture for measuring the eccentricity of a coupling, comprising a base 1, a partition 2 fixedly installed inside the base 1, a first adjusting screw 3 rotatably connected to one side of the base 1 via the partition 2, a fixed clamping block 4 fixedly installed on the base 1, a movable clamping block 5 movably installed on the base 1, a base plate 6 fixedly installed on the base 1 near the fixed clamping block 4, two first guide shafts 8 fixedly installed on the base plate 6, a top plate 7 fixedly connected to the two first guide shafts 8, and a second adjusting screw 3 rotatably connected to the top plate 7 between the two first guide shafts 8. An L-shaped side rod 10 is movably connected between the adjusting screw 9, the first guide shaft 8, and the second adjusting screw 9. An adjusting wheel 12 is movably installed inside the L-shaped side rod 10. A third adjusting screw 25 is threadedly connected inside the adjusting wheel 12. The L-shaped side rods 10 located on both sides of the third adjusting screw 25 are also movably installed with second guide shafts 14. A carrier plate 15 is fixedly connected between the two second guide shafts 14. A dial indicator 16 is fixedly installed on the carrier plate 15. An adsorption plate 17 is fixedly installed at the bottom of the base 1. A top rod 18 is also movably installed inside the base 1 near the partition plate 2.

[0022] like Figures 1-3 As shown, the adsorption plate 17 has a positioning groove 19. The adsorption plate 17 can be positioned and installed on the rail through the positioning groove 19. Multiple magnetic blocks 20 are fixedly installed at the top of the positioning groove 19. After the adsorption plate 17 is installed on the rail through the positioning groove 19, the magnetic blocks 20 can be used to adsorb and fix the adsorption plate 17 on the rail, thereby completing the installation of the base 1. The base 1 has an inner spiral guide hole 21. A spiral guide block is fixedly installed on the inner side of the inner spiral guide hole 21. The top rod 18 has a spiral guide groove 22 on the outer side. The top rod 18 is rotatably connected to the inner spiral guide hole 21 through the spiral guide groove 22. The top rod 18 is installed in the inner spiral guide hole 21 through the outer spiral guide groove 22. When the top rod 18 is rotated, the bottom of the spiral guide groove 22 can be quickly moved out of the inner spiral guide hole 21 and abut against the rail, thereby causing the magnetic block 20 on one side of the top of the positioning groove 19 to disengage from the rail, thus making it easier to remove the base 1 from the rail.

[0023] like Figure 1 , Figure 4As shown, a handwheel is fixedly installed on the top of the second adjusting screw 9, and the second adjusting screw 9 is threadedly connected to one of the screw holes in the L-shaped side rod 10. The cooperation between the first guide shaft 8 and the second adjusting screw 9 enables the vertical movement of the L-shaped side rod 10, thereby adjusting the working height of the dial indicator 16. A mounting groove 11 is provided on one side of the L-shaped side rod 10, and a rotating groove 23 is provided on one side of the mounting groove 11. A limit block 13 is fixedly installed in the mounting groove 11, and a rotating groove 23 is also provided on one side of the limit block 13. Fixing rings 24 are fixedly installed on both sides of the adjusting wheel 12, and the fixing rings 24 are rotatably installed in the corresponding rotating grooves 23. The adjusting wheel 12 rotates in the mounting groove 11, and can rotate on the third adjusting screw 25 through the thread in the middle of the adjusting wheel 12, thereby adjusting the horizontal position of the carrier plate 15, so that the dial indicator 16 can be adjusted to a horizontal position. One end of the third adjusting screw 25 is rotatably installed on one side of the carrier plate 15.

[0024] like Figure 1 As shown, V-shaped grooves are respectively opened on the opposite side of the fixed clamping block 4 and the movable clamping block 5. Opening V-shaped grooves on the opposite side of the fixed clamping block 4 and the movable clamping block 5 can facilitate the clamping of couplings of different diameters.

[0025] It should be noted that this utility model is a measuring tool for measuring the eccentricity of a coupling. When using this measuring tool, it needs to be operated during the current railway downtime. First, the base 1 is inserted into the rail through the positioning groove 19 of the bottom adsorption plate 17. The magnetic block 20 adsorbs the rail to fix the base 1. Then, one end of the coupling is placed on the base 1 and close to the fixed clamping block 4. Then, the knob at one end of the first adjusting screw 3 is manually turned so that the first adjusting screw 3 rotates in the screw hole in the movable clamping block 5, thereby driving the movable clamping block 5 to move on the base 1. It cooperates with the V-shaped groove of the fixed clamping block 4 to clamp couplings of different diameters.

[0026] Rotate the top handwheel of the second adjusting screw 9 to engage with the first guide shaft 8, allowing the L-shaped side rod 10 to move up and down along the first guide shaft 8, adjusting the height of the dial indicator 16. Then rotate the adjusting wheel 12, which rotates within the rotating groove 23 of the mounting groove 11 via the fixing ring 24, driving the third adjusting screw 25 to rotate, causing the carrier plate 15 and the dial indicator 16 to move horizontally along the second guide shaft 14, aligning with the measuring point. During measurement, the dial indicator 16 can measure the coupling deviation radially and axially and display the values.

[0027] During disassembly, rotating the top rod 18 causes its outer spiral guide groove 22 to move within the inner spiral guide hole 21. The bottom of the top rod 18 abuts against the rail, causing the magnetic block 20 to detach from the rail. Consequently, the side of the base 1 away from the top rod 18 abuts against the rail, and the base 1 is tilted as a whole, allowing it to be easily removed from the rail.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
