Description

Technical Field

[0001] The present invention relates to the field of mechanical training equipment, and more particularly to a device for centering a machine pump. Background Art

[0002] In the existing training and learning, the engineering machinery production and maintenance fields hope that employees engaged in mechanical fitters can strengthen the maintenance technology and skills training of mechanical fitters pumps, valves, and pipelines to meet the technical requirements of the machinery production and maintenance fields.

[0003] Among them, the technical requirements for the installation and alignment of construction machinery are particularly high. For example, taking the alignment of motors and pumps as an example, the existing installation and alignment of motors and pumps often use a knife-edge ruler or a steel ruler for measurement and calibration. This method has low alignment accuracy, which seriously affects the operation of the pump and motor. The equipment often has problems such as heating, vibration, and damage. In addition, employees can only accumulate experience in actual operations in daily learning, and are unable to actively discover and solve problems. In the process of learning the installation of motors and pumps, accurate measurement results cannot be obtained due to the lack of auxiliary tools, which makes it impossible for employees to learn from experience well. At the same time, they cannot master their own skills through repeated practice, so that when problems are encountered in actual operations, they need to spend a lot of time to troubleshoot the problems.

[0004] Therefore, it is necessary to design a new type of alignment device to help employees learn the alignment installation of motors and pumps and solve the above problems. Utility Model Content

[0021] Example 1

[0022] A device for centering a machine pump includes: a support frame 4, a clamping mechanism 1, an adjustment mechanism 3 and a measuring mechanism 2. The first support rod and the second support rod of the support frame 4 are vertically fixedly connected, the first support rod is arranged vertically to the ground, the lower end of the first support rod is fixedly connected to the clamping mechanism 1, the adjustment mechanism 3 is slidably connected to the second support rod, and the measuring mechanism 2 is arranged on the adjustment mechanism 3.

[0023] The clamping mechanism 1 includes a clamping ring plate 11 and an adjusting connecting piece 12. There are two clamping ring plates 11 and two adjusting connecting pieces 12. The two clamping ring plates 11 are symmetrically arranged to form a ring structure. One clamping ring plate 11 is fixedly connected to the first support rod, and the two ends of the two clamping ring plates 11 are connected by correspondingly arranged adjusting connecting pieces 12.

[0024] The adjustment mechanism 3 includes an adjustment rod 31 , an adjustment block 33 and a locking member 32 . The adjustment rod 31 is slidably connected to the second support rod through the adjustment block 33 , and the locking member 32 is cooperatively connected to the adjustment block 33 .

[0025] There are two adjusting mechanisms 3 and measuring mechanisms 2. The measuring mechanism 2 includes a measuring element 21, a locking block 22 and a locking nut 23. The measuring element 21 is rotatably connected to the adjusting rod 31 through the locking block 22, and the locking nut 23 is cooperatively connected to the locking block 22.

[0026] The measuring element 21 is provided at the lower end of the adjusting rod 31 .

[0027] The main uses of this device include:

[0028] 1. Centering and installing mechanical components. For example, a motor and a stand-alone pump need to be coaxially aligned. The centering device is clamped to the motor or pump using a clamping mechanism 1. The position of the measuring mechanism 2 is adjusted using an adjustment mechanism 3. Using either the motor or the stand-alone pump as a reference, the measuring mechanism 2 is adjusted. After measuring various values ​​of the reference, the horizontality and verticality of the non-referenced part are measured. After comparing these two values, the non-referenced part is adjusted to meet the results measured by the measuring mechanism 2, achieving centering. This device ensures accurate centering and installation.

[0029] 2. Check the degree of alignment of installed mechanical parts. Taking the motor and stand-alone pump as an example, after the installation of the motor and the stand-alone pump, the staff needs to determine whether the two are installed in an aligned and coaxial manner, whether there is any installation error, and whether the installation error is within the allowable range. The device is clamped on the motor or motor pump by the clamping mechanism 1. With one of the motor or the stand-alone pump as the reference, the position of the measuring mechanism 2 is adjusted by the adjusting mechanism 3 to measure the horizontality and verticality of the two sides, and the error is calculated to determine whether the installation of the motor and the stand-alone pump meets the requirements.

[0030] The working principle of this utility model is as follows: Figure 1 and Figure 2 shown.

[0031] The clamping mechanism 1 is used to clamp mechanical components that require alignment or measurement. The clamping mechanism 1 clamps the mechanical component using two clamping ring plates 11. Adjustable connectors 12 are provided at both ends of the clamping ring plates 11. In this embodiment, the adjustable connectors 12 utilize a bolt and nut combination to adjust the opening angle for installation.

[0032] The measuring mechanism 2 determines the degree of alignment by measuring horizontality and verticality. The measuring mechanism 2 measures horizontality and verticality using two measuring elements 21, respectively. In this embodiment, the measuring elements 21 are dial indicators. The measuring element 21 is rotatably connected to a locking block 22, which is fixed to the end of the adjustment rod 31. The locking block 22 is threadedly connected to a locking nut 23, and the measuring element 21 is limited in position by rotating the locking nut 23. In this embodiment, a rotating shaft is provided at the bottom of the measuring element 21, which passes through the limiting block for rotational connection. The rotating shaft is threaded, and the locking nut 23 is rotated and mounted on the threads. When the locking nut 23 is loosened, the measuring element 21 lacks friction to limit its position, allowing it to be adjusted for rotation. Once adjusted to the desired position, the locking nut 23 is tightened. The locking nut 23 and the end of the rotating shaft clamp the locking block 22, providing friction and limiting the position of the measuring element 21.

[0033] The adjustment mechanism 3 adjusts the position of the measuring mechanism 2 to meet usage requirements. The adjustment block 33 is provided with two mounting holes, through which the adjustment rod 31 and the second support rod are respectively inserted. Both the adjustment rod 31 and the second support rod are provided with waist-shaped holes. The locking member 32 passes through the waist-shaped holes provided in the adjustment rod 31 and the second support rod and is installed on the adjustment block 33. The adjustment block 33 is provided with a screw hole. The locking member 32 is connected to the screw hole provided in the adjustment block 33 via a threaded structure and is locked by rotating the locking member 32. The adjustment rod 31 and the second support rod can be adjusted relative to the adjustment block 33 through the waist-shaped holes to achieve the purpose of adjustment.

[0034] The adjustment function of the measuring mechanism 2 and the adjusting mechanism 3 is used to measure the component to be measured when the location of the component to be measured is relatively hidden and blocked by other adjacent components.

[0035] Example 2

[0036] On the basis of the first embodiment, the clamping mechanism 1 is detachably connected to the motor coupling 52 of the training motor 5, and the training motor 5 and the training pump 6 are arranged on the base 7. The training motor 5 is connected to the base 7 through a spacer 51.

[0037] In the second embodiment, a device is provided that has both the function of pump centering and training. Trainees can use this device to improve their mastery of centering installation technology. Figure 3 and Figure 4 As shown, the training machine pump 6 is fixedly connected to the base 7. Trainees learn and train the centering installation by dismantling the training motor 5 and then installing it and connecting the training machine pump 6 and the training motor 5 through a coupling.

[0038] The device clamps the clamping mechanism 1 on the motor coupling 52 of the training motor 5, and uses the measuring mechanism 2 to measure the horizontality and verticality of the motor coupling 52 to determine whether the motor coupling 52 and the machine pump coupling 61 of the training machine pump 6 are coaxially arranged.

[0039] The specific operation steps of the device are as follows:

[0040] First, remove the training motor 5 from the base 7 and reinstall it on the base 7. Align the motor coupling 52 with the pump coupling 61. Then, clamp the centering device to the motor coupling 52 of the training motor 5 using the clamping mechanism 1. Adjust the position of the measuring mechanism 2 using the adjustment mechanism 3. Using the training pump 6 as a reference, use the measuring mechanism 2 to measure the horizontality and verticality of the outer surface of the pump coupling 61 of the training pump 6, which serves as the reference. After the measurement results are obtained, measure the horizontality and verticality of the outer surface of the reinstalled motor coupling 52. Compare the two measurement results and adjust the position of the training motor 5 to achieve coaxial arrangement of the two couplings. This device can be used for regular technical assessments of staff.

[0041] Furthermore, a height adjustment member is provided between the training motor 5 and the raising frame 51, and the height of the training motor 5 can be adjusted by the height adjustment member. In this embodiment, the height adjustment member is a gasket. Figure 3 As shown, the training motor 5 is mounted on the raising frame 51 by bolts. If it is found after measurement that the height of one side of the training motor 5 is insufficient, affecting the horizontality and verticality, the height can be adjusted by using gaskets to meet the required horizontality and verticality.

[0042] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
