Description

Technical Field

[0001] This utility model relates to the field of concentricity correction technology, and in particular to a correction and detection device for adjusting the concentricity of couplings. Background Technology

[0002] Couplings are essential connecting components between shafts in the operation of mechanical equipment. The concentricity accuracy of the coupling is related to whether the machine can operate normally and will directly affect the subsequent operation quality of the equipment. Therefore, after the coupling is installed, it is necessary to adjust and correct the concentricity of the coupling so that the center lines of the driving shaft and the driven shaft are on the same straight line, thereby ensuring the long-term stable operation of the equipment.

[0003] Currently, the common method for correcting the concentricity of couplings is to use a dial indicator to measure the concentricity of the two shafts, and then use tools such as pry bars or copper rods to add or remove shims or tap to move the motor to make the concentricity of the two shafts meet the specifications. However, the above operation requires manual tapping and prying to adjust the concentricity of the two shafts, and the force of tapping or prying to add or remove shims depends on human experience. Therefore, it is necessary to repeat the adjustment many times to accurately correct the concentricity of the coupling on the two shafts, making the concentricity correction operation of couplings quite troublesome. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a correction and detection device for adjusting the concentricity of couplings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coupling concentricity adjustment and correction detection device includes a base plate and a mounting plate disposed on the base plate. A motor is fixedly mounted on the mounting plate, and a coupling is mounted on the output end of the motor. A slider distributed circumferentially and inclinedly abutting against the mounting plate is slidably disposed on the base plate. A longitudinal groove is formed on the mounting plate, and a transverse groove corresponding to the longitudinal groove is formed on the base plate. A fixing bolt penetrating the transverse groove and the longitudinal groove is provided on the base plate. A nut that presses against the mounting plate is connected to the fixing bolt. A digital display level is mounted on the mounting plate, and a support rod is provided on the base plate. A digital display dial indicator that abuts against the coupling is mounted on the support rod.

[0007] Preferably, the base plate is provided with slide bars that are distributed laterally on both sides of the mounting plate and longitudinally on both sides of the mounting plate, and the slider is slidably disposed on the slide bars.

[0008] Preferably, the base plate is provided with a protective cover located outside the slider, and the protective cover is threaded with abutting bolts that abut against the slider inward.

[0009] Preferably, the protective cover is provided with a top plate that fits against the upper end of the slider.

[0010] Preferably, the slider has a first inclined surface that abuts against the lower end of the mounting plate, and the mounting plate has a second inclined surface that matches the first inclined surface.

[0011] Preferably, a ratchet is provided on one side of the slider, and a stop plate is fixed on the ratchet to abut against the upper end of the mounting plate. A pull rod is provided on the protective cover, and one end of the pull rod is connected to a pawl that abuts against the ratchet teeth of the limiting ratchet.

[0012] Preferably, the pull rod is slidably inserted into the protective cover, and a spring is sleeved on the pull rod. One end of the spring abuts against the outside of the protective cover, and the other end of the spring is connected to the cap of the pull rod.

[0013] Preferably, a rotating rod is fixed on the support rod, and a mounting block is provided on the rotating rod. The mounting block has a mounting hole for mounting a digital dial indicator.

[0014] Preferably, the rotating rod is slidably sleeved on the support rod, the rotating rod is equipped with mounting bolts that abut against the support rod, and the rotating rod has an adjustment groove for the mounting block to slide.

[0015] Preferably, the base plate has a through groove, and the support rod is slidably fixed to the base plate along the through groove.

[0016] The beneficial effects of this utility model are:

[0017] 1. By adjusting the horizontally set slider, the mounting plate is driven to move horizontally left and right. In turn, the mounting plate drives the coupling on the motor to move horizontally left and right, thereby correcting the lateral concentricity of the coupling. Furthermore, by adjusting the horizontally and vertically distributed sliders towards the center or both sides, the mounting plate is driven to move up and down, thereby correcting the vertical concentricity of the coupling. In other words, the concentricity of the coupling is corrected by adjusting the horizontally and vertically set sliders, which improves the accuracy and convenience of the coupling concentricity correction, while ensuring stable and efficient operation of the equipment and reducing production costs.

[0018] 2. The protective cover is equipped with longitudinal and transverse abutment bolts that abut against the slider. By tightening or loosening the abutment bolts, the slider is driven to move longitudinally and transversely. This allows for more precise adjustment and correction of the coupling through the displacement mounting plate, and simplifies the operation of correcting the concentricity of the coupling, making the concentricity correction of the coupling more convenient.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit 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.

[0029] like Figures 1 to 7 As shown, a correction and detection device for adjusting the concentricity of a coupling includes a base plate 1 and a mounting plate 4 disposed on the base plate 1. The mounting plate 4 is spaced apart above the base plate 1. A motor 6 is fixedly mounted on the mounting plate 4. A coupling 61 is mounted on the output end of the motor 6. An output shaft 62 for outputting power is mounted on the other side of the coupling 61.

[0030] The base plate 1 is provided with support rods 5 and a display screen 7. Specifically, the support rods 5 are equipped with digital dial indicators that abut against the coupling 61. The digital level 45 and the digital dial indicator are electrically connected to the display screen 7. There are two support rods 5 and two digital dial indicators, which are fixed on the two support rods 5 respectively. A part of the coupling 61 is installed on the output end of the motor 6, and the other part of the coupling 61 is installed on the output shaft 62, thereby transmitting the power of the motor 6 to the output shaft 62 through the coupling 61.

[0031] The base plate 1 has a through groove 13, and the support rod 5 is slidably fixed on the base plate 1 along the through groove 13. A rotating rod 51 is fixed on the support rod 5, and a mounting block 53 is provided on the rotating rod 51. The mounting block 53 has a mounting hole 531 for mounting a digital dial indicator, so that the concentricity of the coupling 61 can be detected by the digital dial indicator.

[0032] Furthermore, the rotating rod 51 is slidably sleeved on the support rod 5, and the rotating rod 51 is equipped with a mounting bolt 52 that abuts against the support rod 5. The height of the digital dial indicator can be adjusted by sliding the rotating rod 51 up and down. The rotating rod 51 is provided with an adjustment groove 511 for the mounting block 53 to slide. The mounting block 53 can slide along the adjustment groove 511 to adjust the relative position of the digital dial indicator, so that the digital dial indicator can meet the needs of motors 6 of different sizes.

[0033] The base plate 1 is slidably provided with sliders 2 that are distributed circumferentially and inclined to abut against the mounting plate 4. Specifically, the sliders 2 are provided with a first inclined surface 21 that abuts against the lower end of the mounting plate 4. The mounting plate 4 is provided with a second inclined surface 41 that is adapted to the first inclined surface 21. The first inclined surface 21 and the second inclined surface 41 fit and abut against each other.

[0034] The base plate 1 is provided with slide bars 12 that are distributed laterally on both sides of the mounting plate 4 and longitudinally on both sides of the mounting plate 4. That is, the slide bars 12 are distributed around the mounting plate 4. The slider 2 is provided with a groove 22 that matches the slide bar 12. The slider 2 is slidably disposed on the slide bar 12 through the groove 22. The slider 2 can slide along the direction of the slide bar 12.

[0035] The mounting plate 4 has a longitudinal groove 42, and the base plate 1 has a transverse groove 11 that corresponds to the longitudinal groove 42 vertically. The transversely distributed slide bars 12 are parallel to the transverse grooves 11, and the longitudinally distributed slide bars 12 are parallel to the longitudinal grooves 42.

[0036] Furthermore, the base plate 1 is provided with a fixing bolt 43 that passes through the horizontal groove 11 and the vertical groove 42. The fixing bolt 43 is connected to a nut 44 that presses against and fixes the mounting plate 4, so that the mounting plate 4 is abutted and fixed on the slider 2 by the fixing bolt 43 and the nut 44.

[0037] By loosening the nut 44 on the fixing bolt 43 and adjusting the horizontally arranged slider 2, the mounting plate 4 is driven to move horizontally left and right. The horizontal groove 11 cooperates with the fixing bolt 43 to guide the horizontal movement of the mounting plate 4. The mounting plate 4 drives the coupling 61 on the motor 6 to move horizontally left and right to correct the horizontal concentricity of the coupling 61.

[0038] Furthermore, by adjusting the horizontally and vertically distributed sliders 2 towards the center or both sides, the mounting plate 4 is driven to move up and down. That is, by adjusting the horizontally and vertically distributed sliders 2 towards the center, the mounting plate 4 can be driven to move upward through the sliders 2; by adjusting the horizontally and vertically distributed sliders 2 towards both sides, the mounting plate 4 can be driven to move downward through the sliders 2, thereby correcting the concentricity of the coupling 61. That is, the concentricity of the coupling 61 is corrected by adjusting the horizontally and vertically distributed sliders 2. In addition, a digital display level 45 is installed on the mounting plate 4, so as to adjust and fix the mounting plate 4 and the motor 6 horizontally through the digital display level 45.

[0039] The base plate 1 is provided with a protective cover 3 located outside the slider 2. The protective cover 3 is threaded with abutting bolt 31 that abuts against the slider 2 inward. The protective cover 3 is provided with a top plate 32 spaced apart from the upper end of the slider 2, so as to limit the upper end of the slider 2 through the top plate 32.

[0040] By setting longitudinal and transverse abutment bolts 31 on the protective cover 3 to abut against the slider 2, the slider 2 can be driven to move longitudinally and transversely by tightening or loosening the abutment bolts 31. This allows for more precise adjustment and correction of the coupling 61 through the displacement mounting plate 4. In other words, by tightening the abutment bolts 31, the operation of correcting the concentricity of the coupling 61 is simplified, making the concentricity correction of the coupling 61 more convenient and improving the accuracy and convenience of the concentricity correction. At the same time, it ensures that the equipment can operate stably and efficiently, and reduces production costs.

[0041] Furthermore, a ratchet 24 is provided on one side of the slider 2. The ratchet 24 can rotate relative to the side of the slider 2. A stop plate 23 is fixed on the ratchet 24 and abuts downward against the upper end of the mounting plate 4. The stop plate 23 presses downward against the upper end of the mounting plate 4 to limit the upward movement of the mounting plate 4, thereby ensuring the reliability of the mounting plate 4 in lateral displacement to correct and adjust the concentricity of the coupling 61.

[0042] Specifically, the protective cover 3 is provided with a pull rod 26, one end of which is connected to a pawl 25 that abuts against the ratchet teeth of a limiting ratchet 24. The pawl 25 rotates and abuts against the ratchet teeth of the ratchet 24 to limit the counterclockwise rotation of the ratchet 24 (see reference). Figure 4(as shown in the reverse direction), at this time, the abutment 23 cannot rotate counterclockwise, that is, the upward movement of the mounting plate 4 is limited.

[0043] The pull rod 26 is slidably inserted into the protective cover 3. A spring 27 is sleeved on the pull rod 26. One end of the spring 27 abuts against the outside of the protective cover 3, and the other end of the spring 27 is connected to the abutment cap 261 of the pull rod 26. When the abutment cap 261 of the pull rod 26 is pressed inward, the spring 27 is compressed and the pull rod 26 drives the pawl 25 to rotate. The pawl 25 then rotates to the ratchet tooth away from the ratchet 24. At this time, the mounting plate 4 can abut against the abutment plate 23 and move upward to adjust the height.

[0044] This embodiment also discloses a correction and detection method for adjusting the concentricity of a coupling, including the following steps:

[0045] a. A slider 2 that is inclined to abut against the mounting plate 4 is slidably set on the base plate 1. A digital display level 45 is set on the mounting plate 4. A digital display dial indicator that abuts against the coupling 61 is set on the support rod 5 of the base plate 1. The concentricity of the coupling 61 is detected by the digital display dial indicator. The digital display level 45 and the digital display dial indicator are electrically connected to the display screen 7.

[0046] b. By loosening the nut 44 on the fixing bolt 43, the mounting plate 4 can be moved laterally along the transverse groove 11 or longitudinally along the longitudinal groove 42.

[0047] c. Adjust the longitudinally distributed slider 2 by sliding it synchronously back and forth to drive the motor 6 to move back and forth and adjust the installation position;

[0048] d. Adjust the horizontally distributed slider 2 by sliding it synchronously left and right to drive the mounting plate 4 to move horizontally left and right, thereby correcting and adjusting the lateral concentricity of the coupling 61.

[0049] e. By adjusting the horizontally and vertically distributed sliders 2 towards the center or both sides, the mounting plate 4 is driven to move up and down, thereby correcting and adjusting the concentricity of the coupling 61.

[0050] f. Adjust the level of the mounting plate 4 by observing the value of the digital display level 45, and fix the mounting plate 4 horizontally by tightening the nuts 44 on the fixing bolts 43, and adjust and fix the motor 6 and the coupling 61.

[0051] g. The detected values ​​are transmitted to the display screen 7 in real time through the digital display level 45 and the digital display dial indicator. When the detected value is greater than the set value, that is, when the position of the motor 6 or the coupling 61 is offset during operation and the offset value is too large and will affect the normal operation of the equipment, an alarm signal can be issued so that the concentricity and the installation position of the motor can be readjusted and corrected in time.

[0052] Furthermore, the detection data from the display screen 7 can also be uploaded via Bluetooth to record data such as concentricity in a timely manner.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
