Description
Technical Field
The utility model belongs to the technical field of the mechanical overhaul, concretely relates to a device that is used for pump centering accurate adjustment.
Background
The coupler is used for connecting the water pump and the driving device, so that the rotating shaft of the coupler synchronously rotates and transmits certain torque, and meanwhile, an axial space is provided for the maintenance of the water pump. The centering of shaft coupling is the basic project that the water pump overhauld, and poor centering probably leads to equipment vibration, bearing wearing and tearing, sealing member wearing and tearing, efficiency reduction scheduling problem.
The most common centering method is a dial indicator method, and the adjustment amount of the position of the base and the number of the plus-minus adjusting pads are calculated by measuring the excircle deviation and the opening deviation between the driving shaft coupler and the driven shaft coupler.
The base position is usually adjusted by a copper bar knocking method, the knocking force is difficult to control, and the position of the dial indicator can be changed in the knocking process. In the process of adding and subtracting the gasket, the foundation bolt needs to be loosened and then the base is pried, so that the position of the base can be changed. Therefore, to meet the requirements of coaxiality and parallelism, multiple measurement, calculation and adjustment processes are often required, and the overhaul period and the cost control are not facilitated.
Disclosure of Invention
An object of the utility model is to provide a device for pump centering accurate adjustment to accomplish the centering of water pump shaft coupling fast accurately.
In order to achieve the above purpose, the utility model adopts the technical proposal that:
a device for centering and fine adjustment of a pump comprises an L-shaped bracket, a bolt, a pushing screw rod and a nut; the center of the bottom plate of the L-shaped bracket is provided with a hole and is fixed on the equipment base through a bolt; the side wall of the L-shaped bracket is provided with a guide screw hole for installing a pushing screw rod and a nut.
The pushing screw consists of a screw rod, a pushing head and an inner hexagon screw, and the pushing head is fixed on the screw rod through the inner hexagon screw.
The pushing head is made of PA6.6 nylon.
The utility model discloses the beneficial effect who gains does:
the utility model discloses can avoid the process of measuring many times, calculating and adjusting in the traditional approach, realize accomplishing the purpose of water pump shaft coupling centering fast, accurately.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the device for precisely adjusting the centering of the pump of the present invention comprises: the device comprises an L-shaped bracket 1, a hexagon head bolt 2, a pushing screw rod 3 and a hexagon nut 4; the L-shaped bracket 1 is fixed on the equipment base through a bolt 2; the side wall of the L-shaped bracket 1 is provided with a guide screw hole for installing a pushing screw rod 3 and a nut 4. The two openings may be sized according to the device interface.
The pushing screw 3 consists of a screw 3.1, a pushing head 3.2 and a hexagon socket screw 3.3. The pushing head 3.2 is made of PA6.6 nylon and is fixed on the screw rod 3.1 through a hexagon socket head cap screw 3.3. The pushing screw 3 is matched with the nut 4 and the L-shaped bracket 1 for use.
The center of the bottom plate of the L-shaped bracket 1 is provided with a hole according to the size of the fabrication hole of the bottom plate of the equipment, and can be fixed on the base of the equipment by using a bolt 2; the side wall of the L-shaped bracket 1 is provided with a guide screw hole for installing a pushing screw rod 3 and a nut 4; the pushing head 3.2 at the end part of the screw rod is made of nylon materials, and the contact surface of equipment is protected in the pushing process.
By the method, the position of the base can be accurately adjusted by matching with the dial indicator. After each foot pushing tool is locked, the position change of the machine base in the gasket adding and reducing process can be limited, so that the centering of the water pump coupler is completed quickly and accurately.
Realize the technical scheme of the utility model, including following step:
step 1: a set of (4 in total) pushing tools are arranged on a bottom plate of the driving device, and the bolt 2 is screwed down.
Step 2: and the frame meter measures and records the excircle deviation and the opening deviation between the driving shaft coupler and the driven shaft coupler.
And step 3: and determining the position adjusting direction of the driving device according to the excircle deviation.
And 4, step 4: and adjusting the pushing tool nuts 4 on the left side and the right side of the driving device in a matching manner according to the adjusting direction, and observing the reading change of the excircle dial indicator at the same time until the left and right position deviation of the axes of the driving shaft and the driven shaft is eliminated. The nut 4 is tightly driven by a tool, so that the 4 pushing heads 3.2 are all tightly pushed against the driving device.
And 5: and (5) turning to retest the excircle deviation and the opening deviation, calculating the thickness of the gasket required to be increased or decreased by each foot margin of the driving device, and adjusting the thickness of the gasket according to the calculation result.
Step 6: and (5) repeating the step until the adjustment result meets the coaxiality and parallelism requirements.
And 7: and (4) removing the pushing tool.
