The utility model is further described below with reference to the accompanying drawings:
example 1: as shown in fig. 1-3, a coaxiality calibration device for a single-stage single-suction cantilever centrifugal pump coupler comprises an adjusting component 2, wherein a second dial indicator 8 is installed on the adjusting component 2, two ends of the adjusting component 2 are respectively hinged with connecting rods, an adjusting groove 5 is formed in one end of each connecting rod, a sheep angle nail 7 is arranged in each adjusting groove 5, a fixing component 3 is arranged at the other end of one connecting rod, and a first dial indicator 4 is fixedly arranged at the other end of the other connecting rod.
Specifically, the connecting rod includes first connecting rod 1 and second connecting rod 6, and fixed subassembly 3 installs on second connecting rod 6, and first percentage table 4 is installed on first connecting rod 1, and the adjustment tank 5 position on first connecting rod 1 and the second connecting rod 6 is relative, so set up can measure radial runout volume according to the rotation of two connecting seats, be convenient for calibrate.

Specifically, the number of the second dial indicators 8 is two, the two second dial indicators are respectively installed on the two connecting pipes 203, and the maximum installation distance between the two second dial indicators 8 is smaller than the diameter of the coupler, so that the two dial indicators can be measured along the position closest to the maximum diameter of the coupler, and the reading change of the dial indicators can be more obvious through the position measurement close to the maximum diameter.
Specifically, the distance L between the axis of the installation direction of the first dial indicator 4 and the axis of the screw 304 is greater than the radius of the installation hole 11, so that the measurement position of the first dial indicator 4 can be ensured to be on the side wall of the coupler, and the insertion of the measurement probe into the installation hole 11 is avoided.
The working procedure of this embodiment is: the device is used for fine adjustment after the primary adjustment of the input shaft and the motor output shaft of the single-stage single-suction cantilever type centrifugal pump, and because the rotating speed of the single-stage single-suction cantilever type centrifugal pump is higher, the coaxiality requirement on the input shaft and the motor output shaft of the single-stage single-suction cantilever type centrifugal pump is higher during installation, and the error generally needs to be controlled within 1.0mm, so that the error between the input shaft and the motor output shaft of the single-stage single-suction cantilever type centrifugal pump is already controlled within 1.0mm during fine adjustment.
The coupling for connecting the single-stage single-suction cantilever centrifugal pump and the motor comprises two connecting seats and a transmission joint for transmitting power between the two connecting seats, wherein one connecting seat is arranged on an output shaft of the motor, the other connecting seat is arranged on an input shaft of the single-stage single-suction cantilever centrifugal pump, and the first connecting seat 9 and the second connecting seat 10 are used for distinguishing the using process and the principle of the device for convenience.
Before fine adjustment is performed by using the device, a worker needs to connect the fixing component 3 on the second connecting rod 6 with the second connecting seat 10, one end of a bolt is inserted into the mounting hole 11 on the second connecting seat 10 during connection, then the rotating block 303 is rotated to complete connection through mutual matching of threads and threads on the inner wall of the mounting hole 11, then the position of the claw nail 7 on the second connecting rod 6 is adjusted through the adjusting groove 5 on the second connecting rod 6 to be aligned with one of the mounting holes 11 on the side wall of the second connecting seat 10 and screwed into the mounting hole, after the claw nail 7 is completely fixed, the position of the claw nail 7 on the first connecting rod 1 is adjusted through the adjusting groove 5 on the first connecting rod 1, so that the claw nail 7 on the first connecting rod 1 is aligned with one of the mounting holes 11 on the side wall of the second connecting seat 10 and screwed into the mounting hole 11, after two sheep horn nails 7 are screwed into the mounting holes 11, the rotation synchronism of the first connecting seat 9 and the second connecting seat 10 can be ensured when fine adjustment is carried out, then a worker confirms that the measuring ends of the first dial indicator 4 and the two second dial indicators 8 are in contact with the first connecting seat 9 and ensure that the readings of the gauge needles are larger than zero, then the worker starts to rotate the first connecting seat 9 and the second connecting seat 10, if the coaxiality of the input shaft of the single-stage single-suction cantilever centrifugal pump and the output shaft of the motor is slightly deviated, the readings of the first dial indicator 4 and the second dial indicator 8 can be changed in the rotation process, the worker can determine the position of the coaxiality deviation through the change of the readings and pertinently adjust, and finally the coaxiality error is enabled to be within an allowable range.
When the first connecting seat 9 and the second connecting seat 10 after rotation move axially relatively, the readings of the two second dial indicators 8 change, because the second connecting rod 6 is riveted with the second connecting rod 6 through the rubber rivet 302, and the rubber rivet 302 has certain elasticity, when the first connecting seat 9 and the second connecting seat 10 move axially during adjustment, the tensile force acting on the second connecting rod 6 can be eliminated through the elastic deformation of the rubber rivet 302, and when the first connecting seat 9 and the second connecting seat 10 deviate radially, the transmission of the force can be counteracted through the elastic deformation of the rubber rivet 302, and meanwhile, as the first connecting rod 1 and the second connecting rod 6 are hinged with the adjusting component 2, the transmission of the force can be effectively eliminated when the first connecting seat 9 and the second connecting seat 10 move axially, so that the accuracy of the measurement result can be ensured, and the stress damage of the device can be avoided.
After the adjustment is finished, the workers unscrew the bolts and the sheep nails 7 on the fixing assembly 3 from the mounting holes 11 respectively, then the device is detached from the first connecting seat 9 and the second connecting seat 10, and the positions of the first dial indicator 4 and the second dial indicator 8 can be adjusted in advance because the sizes of the couplings between the single-stage single-suction cantilever centrifugal pump and the motor are the same, so that the readings larger than zero exist on the first dial indicator 4 and the second dial indicator 8 after the installation are ensured, and finally the readings are fixed on the fixing rod and the first connecting rod 1, so that the links of on-site installation adjustment can be reduced, the installation time is saved, and the working efficiency is improved.
The device adopts the claw nail 7 to fix the connecting rod on the two connecting seats of the coupler, but because the error range of the two connecting seats is very small after initial adjustment, the jump is very small when rotating, and smaller elastic deformation can occur under the action of external force when matching with elastic materials, so that although the two connecting seats are connected through the connecting rod, the error amount which can be measured by the dial indicator can still occur when rotating, and therefore, the measurement through the dial indicator when rotating after connecting the two connecting seats by adopting the connecting rod accords with the actual use condition.
The utility model has the core uses of setting up the dial indicator and realizing the connection of two connecting seats at the same time, so that the shape is not fixed and can be designed arbitrarily (because the coupler has various forms), namely, the utility model can achieve the purpose of use by replacing the traditional three sets of dial indicator frames with one dial indicator frame.
The tool can be made of various materials, but is a stressed component, and the lighter and better the tool is under consideration of the strength and the weight of the tool and the premise of ensuring certain strength. The fixed nail 7 can be replaced by other screws with the same screw buckle, but the nail 7 is most convenient to use, the fastening is finished by the mobile phone shell, other screws are used, corresponding fastening tools are needed to be equipped, and inconvenience is increased, so that the nail 7 is optimal.
The foregoing describes one embodiment of the present utility model in detail, but the disclosure is only a preferred embodiment of the present utility model and should not be construed as limiting the scope of the utility model. All equivalent changes and modifications within the scope of the present utility model are intended to be covered by the present utility model.
