Abstract
Description
Technical Field
[0001] The present application relates to the technical field of equipment debugging, and in particular to a concentricity adjustment device. Background Art
[0002] In mining machinery and equipment, motors are used as power input devices for hoists, horizontal centrifugal pumps, ventilators, etc. When the motor is matched and installed with the equipment, the concentricity correction needs to be completed so that the center lines of the driving shaft and the driven shaft are on the same horizontal line. Excessive concentricity deviation will lead to poor operating stability of the motor and equipment, damage to parts, shortened equipment service life, and even serious equipment downtime.
[0003] Traditionally, the concentricity calibration of the motor shaft is done by workers holding a tapping tool, tapping symmetrically along the bottom and top of the motor main body in turn, and then slightly moving the motor to observe the dial indicator reading. During the calibration process, the dial indicator is used to measure once each tap. The manual tapping method is difficult to control, resulting in repeated calibration during the adjustment process. This method is inefficient and labor-intensive for workers. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0022] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0023] The concentricity adjustment device shown in the figure includes: a base 1, a motor bracket 2, a first nut 31, a second nut 32, a third nut 33, a fourth nut 34 and a screw rod 4. The base 1 is set at the placement point of the motor 5, a mounting hole is opened on the base 1, and an anchor bolt 8 passes through the mounting hole to connect the motor bracket 2 with the base 1. The motor bracket 2 is used to support and install the motor 5.
[0024] The first nut 31, the second nut 32, the third nut 33, and the fourth nut 34 are vertically welded on the seat. The nuts 3 are distributed on the left and right sides of the motor bracket 2, and a pair of nuts 3 are symmetrically distributed on each side. The first nut 31 is located on the left front side of the motor bracket 2, the second nut 32 is located on the right front side of the motor bracket 2, the third nut 33 is located on the left rear side of the motor bracket 2, and the fourth nut 34 is located on the right rear side of the motor bracket 2. Screws 4 are respectively installed in the nuts 3. The screws 4 are perpendicular to the motor bracket 2, and the ends of the screws 4 abut against the motor bracket 2 for adjusting the motor bracket 2. By adjusting the screws 4 in the first nut 31, the second nut 32, the third nut 33, and the fourth nut 34, the motor bracket 2 can be adjusted from the left front, the right front, the left rear, and the right rear. By tightening the adjusting screw 4, the motor bracket 2 is displaced as the screw 4 thread changes, and the motor 5 can be displaced with high precision from the left front, the right front, the left rear, and the right rear.
[0025] During installation, the motor 5 is installed on the motor bracket 2, and the motor shaft 7 is connected to the driven shaft of the driven device through the coupling 6. After the connection is completed, the adjustment is performed. The anchor bolts 8 fixing the motor bracket 2 are loosened so that the adjusting screw 4 can cause displacement of the motor bracket 2, and then the screw 4 is screwed in turn for adjustment. When the screw 4 is tightened, the movement amplitude is transmitted according to the pitch size. The displacement amplitude of the motor bracket 2 is weak, and the concentricity of the motor 5 coupling 6 can be accurately fine-tuned.
[0026] Furthermore, in order to obtain the adjustment status of the device in time and avoid repeated measurements causing labor waste, the device also includes a laser transmitter, a laser receiver and a controller. The laser transmitter is installed on the motor shaft 7, the laser receiver is installed on the coupling 6, and the controller is connected to the laser transmitter and the laser receiver.
[0027] The laser transmitter emits a focused laser beam on the driving shaft of the motor 5. The laser receiver on the coupling 6 is used to receive the laser beam. The controller is used to receive the transmission and reception of the laser transmitter and the laser receiver to determine the concentricity correction state. When the concentricity adjustment between the coupling 6 and the driving shaft of the motor 5 is inaccurate, the laser beam will cause interference on the laser receiver. The controller can compare and analyze the interference pattern to determine the concentricity adjustment situation. When the controller receives the interference signal, it prompts that the concentricity correction has not been completed. When the light beam emitted by the emitting device is accurately received by the receiving device, the controller prompts that the correction is completed.
[0028] Finally, it should be noted that, in this article, relationships such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms include, include or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
