Description

Technical Field

[0001] This application relates to the field of water pump testing technology, and in particular to an adjustable torque meter bracket and a torque detection device. Background Technology

[0002] Water pumps are machines that transport or pressurize liquids and are widely used in various fields. Before mass production, water pumps need to be tested for various parameters. For example, torque sensors are commonly used to test the power, torque, and efficiency of the pump shaft. Specifically, the torque sensor is connected between the pump shaft and the motor shaft, and the test is performed by measuring the torque output from the motor. When the torque sensor is connected between the pump shaft and the motor shaft, it needs to be supported and positioned using tooling to ensure the accuracy of the test.

[0003] However, in actual testing, the diverse sizes of motors and pumps necessitate that torque sensors adapt to different installation positions, requiring multiple fixtures with varying support heights, thus increasing fixture costs. Furthermore, existing support fixtures cannot guarantee the alignment of the torque meter and motor shaft. Motor vibrations can affect this alignment, compromising test accuracy.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model.

[0034] The structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this utility model can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0035] The orientations or positional relationships indicated by terms such as "upper," "lower," "left," "right," "middle," "longitudinal," "transverse," "horizontal," "inner," "outer," "radial," and "circumferential" used in this specification are based on the orientations or positional relationships shown in the accompanying drawings and are only for the purpose of simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] As described in the background section, existing torque meter support fixtures typically only match pumps and motors of a single size, resulting in poor versatility. Testing pumps and motors of different sizes requires multiple fixtures, leading to high testing costs. Furthermore, existing support fixtures are usually set up independently of the motor. When the motor vibrates, the alignment of the torque meter and the motor shaft is affected, compromising testing accuracy.

[0037] To address this, this utility model provides an adjustable torque meter bracket, which includes:

[0038] The transition connecting frame 1 has a first connecting side and a second connecting side on both sides along the thickness direction. The first connecting side is provided with an assembly structure for detachably fixing to the housing of the motor 3.

[0039] The adjustable support plate 2 includes a connecting part 201 connected to the second connecting side and a support part 202 for supporting the torque meter 6. A first adjustment structure 4 for adjusting the support height of the adjustable support plate 2 is provided between the connecting part 201 and the transition connecting frame 1. A second adjustment structure 5 for adjusting the axial distance of the torque meter 6 relative to the motor 3 is provided on the support part 202.

[0040] According to the adjustable torque meter bracket provided in this embodiment, by adjusting the support height of the adjustable support plate 2 through the first adjustment structure 4, the torque meter 6 can be finely adjusted in the vertical direction, thereby achieving coaxial positioning of the torque meter 6 with the rotating shaft of the motor 3 and the pump shaft. By adjusting the axial distance of the torque meter 6 relative to the motor 3 through the second adjustment structure 5, the torque meter 6 can be finely adjusted in the axial direction, thereby achieving coaxial connection of the torque meter 6 with the rotating shaft of the motor 3 and the pump shaft. Thus, this adjustable bracket allows for fine-tuning of the torque meter 6 in both radial and axial directions, enabling it to be matched with motors and pumps of different sizes, providing strong versatility and significantly reducing tooling and maintenance costs.

[0041] In addition, this adjustable bracket can achieve a transitional connection between the adjustable support plate 2 and the motor 3 through the transition connecting frame 1. This allows the torque meter 6 to be directly mounted on the housing of the motor 3, making the torque meter 6 and the motor 3 an integrated structure. When the motor 3 vibrates during operation, the torque meter 6 can vibrate at the same frequency as the motor 3, thereby ensuring that the shafts of the torque meter 6 and the motor 3 remain aligned. This avoids the problem of poor alignment between the torque meter 6 and the shaft caused by the vibration of the motor 3, and improves the testing accuracy.

[0042] It should be noted that, for the sake of clarity and context, the term "axial / axial direction" as used throughout this application is defined with reference to the axial direction of the motor shaft.

[0043] The adjustable torque meter bracket provided in the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0044] according to Figure 1 An example is shown of an adjustable torque meter bracket according to at least one embodiment of the present invention. The adjustable torque meter bracket includes: a transition connecting frame 1 and an adjustable support plate 2.

[0045] The transition connecting bracket 1 is used to detachably fix itself to the housing of the motor 3, particularly to the end of the motor 3 housing corresponding to the rotating shaft. This ensures that the adjustable support plate 2, after being mounted on the transition connecting bracket 1, is aligned with the rotating shaft of the motor 3, facilitating the connection and engagement of the torque meter 6 with the rotating shaft. For example, see... Figure 2The transition connecting frame 1 has a first connecting side and a second connecting side on both sides along the thickness direction. The first connecting side is fixed by the assembly structure and the housing of the motor 3, and the second connecting side is used to install the adjustable support plate 2.

[0046] See Figure 1 In this embodiment, the transition connecting frame 1 specifically includes a connecting plate 101 and a mounting plate 102, and the connecting plate 101 and the mounting plate 102 are stacked along the thickness direction. The connecting plate 101 is used to connect and fix to the housing of the motor 3, that is, the first connecting side is the side of the connecting plate 101 away from the mounting plate 102, and the mounting plate 102 is used to install the adjustable support plate 2, that is, the second connecting side is the side of the mounting plate 102 away from the connecting plate 101.

[0047] More specifically, in this embodiment, the shape of the connecting plate 101 matches the contour of the outer ring of the motor end cover assembly, for example, in Figure 2 In the example, the outer ring of the motor end cover assembly has a circular outline. Therefore, the connecting plate 101 can be set as an arc-shaped plate that matches this circular outline, allowing the connecting plate 101 to fit better onto the motor end cover. Of course, if the outer ring of the motor 3 housing has a different shape, the connecting plate 101 can be set to a corresponding shape for installation.

[0048] In this embodiment, the assembly structure includes a connecting hole 1011 and a fastener, wherein, see Figure 2 The connecting plate 101 is provided with two or more connecting holes 1011 that match the mounting holes on the motor end cover, for example, Figure 2 An example is shown where four connection holes 1011 are provided, each corresponding to one of the four mounting holes on the outer ring of the motor end cover. Existing bolt and nut assemblies can be used as fasteners. During installation, the bolts and nuts are engaged with the corresponding connection holes 1011 and mounting holes to secure the connecting plate 101 to the motor 3 housing.

[0049] See Figure 2 In this embodiment, the mounting plate 102 is disposed on the side of the connecting plate 101 opposite to the motor 3. The mounting plate 102 is provided with a mounting structure, through which the adjustable support plate 2 can be mounted on the mounting plate 102. This mounting structure will be described in detail below in conjunction with the specific structure of the adjustable support plate 2. Thus, through the mounting plate 102 and the mounting structure on it, the adjustable support plate 2 and the transition connecting frame 1 can be connected and fixed.

[0050] In addition, in this embodiment, the mounting plate 102 and the connecting plate 101 can be fixed in a non-removable manner, for example, they can be fixed by integral molding or welding. Based on this non-removable design, in order to match motors 3 of different sizes, multiple sets of connecting holes 1011 can be provided on the connecting plate 101. Each set of connecting holes 1011 can match a motor 3 of a certain size, so that this transition connecting frame 1 can be used for motors 3 of various sizes.

[0051] In other embodiments, the mounting plate 102 and the connecting plate 101 can also be fixed in a detachable manner, for example, they can be fixed together by bolt assembly. Based on this detachable design, in order to match motors 3 of different sizes, multiple connecting plates 101 of different sizes can be set. Each connecting plate 101 can match a motor 3 of a certain size, so that the transition connecting frame 1 can also be used for motors 3 of various sizes.

[0052] Based on the above structural design, the transition connecting frame 1 can realize the transitional connection between the adjustable support plate 2 and the motor 3. This allows the torque meter 6 to be directly mounted on the housing of the motor 3 through this adjustable bracket, making the torque meter 6 and the motor 3 an integrated structure. When the motor 3 vibrates during operation, the torque meter 6 can vibrate at the same frequency as the motor 3, so that the shafts of the torque meter 6 and the motor 3 can always remain aligned. This avoids the problem of poor alignment between the shafts of the torque meter 6 and the motor 3 caused by the vibration of the motor 3, and improves the testing accuracy.

[0053] See Figure 1 In this embodiment, the adjustable support plate 2 is installed on the transition connecting frame 1. Specifically, the adjustable support plate 2 is installed on the mounting plate 102 of the transition connecting frame 1. It is mainly used to support the torque meter 6 so that the height of the torque meter 6 can match the height of the motor shaft and the pump shaft.

[0054] For details, see Figure 1 The adjustable support plate 2 includes a connecting part 201 and a support part 202. The connecting part 201 is used to connect with the transition connecting frame 1, and the support part 202 is used to support the torque meter 6. For example, see Figure 1 The adjustable support plate 2 is an L-shaped plate. One of the plates is a vertical plate, which is the connecting part 201, used to fit and install with the mounting plate 102. The other plate is a horizontal plate, which is the support part 202, used to horizontally support the torque meter 6.

[0055] More specifically, in this embodiment, the connecting part 201 is mounted on the mounting plate 102 of the transition connecting frame 1 via a mounting structure, see [link to documentation]. Figure 1The installation structure specifically includes a first adjustment structure 4. The first adjustment structure 4 is used to adjust the support height of the adjustable support plate 2 so that the height of the torque meter 6 matches the height of the rotating shaft and the pump shaft. The second purpose is to fasten the adjustable support plate 2 and the transition connecting frame 1 to ensure the support stability of the adjustable support plate 2.

[0056] For example, see Figure 1 , Figure 2 and Figure 3 The first adjustment structure 4 includes a first adjustment hole 401, a first locking hole 402, and a first locking bolt 403. The first adjustment hole 401 is a strip-shaped hole extending vertically on the connecting part 201. The first locking hole 402 is a threaded hole on the mounting plate 102. The first locking bolt 403 is threadedly matched with the first locking hole 402. The width of the first adjustment hole 401 is greater than the diameter of the shank of the first locking bolt 403 but smaller than its head diameter. During installation, the first adjustment hole 401 is aligned with the first locking hole 402. Then, the shank of the first locking bolt 403 passes through the first adjustment hole 401 from the outside to the inside and is threadedly connected to the first locking hole 402. At this time, the head of the first locking bolt 403 is located on the side of the connecting part 201 away from the transition connecting frame 1. Then, rotate the first locking bolt 403 until its head is pressed against the connecting part 201. This locks the connecting part 201 onto the mounting plate 102. When adjusting the support height of the adjustable support plate 2, loosen the first locking bolt 403 and adjust the adjustable support plate 2 up and down. Once the required support height is achieved, tighten the first locking bolt 403. Thus, the first adjustment structure 4 allows for adjustment of the support height of the adjustable support plate 2 to accommodate motors 3 and pumps of different sizes, providing greater versatility.

[0057] Further, see Figure 3 The first adjustment structure 4 is provided in two sets, and the two sets of first adjustment structures 4 are symmetrically arranged with respect to the rotating shaft of the motor 3. The connection stability between the adjustable support plate 2 and the transition connecting frame 1 can be improved through the two sets of adjustment structures, thereby improving the support stability of the torque meter 6.

[0058] Furthermore, in this embodiment, each group of first adjusting structures 4 has two first locking holes 402 and two first locking bolts 403. See also Figure 3Two first locking holes 402 are arranged vertically so that they can be synchronously aligned with the first adjusting hole 401, and both first locking bolts 403 pass through the first adjusting hole 401. Thus, the connection strength between the adjustable support plate 2 and the transition connecting frame 1 is improved through the connection and cooperation of the two first locking holes 402 and the two first locking bolts 403, ensuring the stability of the torque meter 6. Furthermore, the two first locking bolts 403 also guide the vertical movement of the adjustable support plate 2, preventing it from tilting during raising and lowering, and ensuring the stability of the adjustable support plate 2's height adjustment.

[0059] Furthermore, in this embodiment, the mounting structure also includes a positioning groove 103, which is disposed on the mounting plate 102. The connecting part 201 is vertically movable and embedded in the positioning groove 103. The positioning groove 103 can provide guidance for the lifting and lowering of the connecting part 201 and limit the two sides of the connecting part 201 to ensure the stability of the lifting and lowering adjustment of the adjustable support plate 2. Moreover, when the connecting part 201 is installed in the positioning groove 103, the first adjustment hole 401 on the connecting part 201 is exactly aligned with the first locking hole 402 on the mounting plate 102, which facilitates the quick assembly of this adjustable bracket.

[0060] For example, see Figure 2 The mounting plate 102 has two vertically extending limiting rods protruding from its surface. The portion between the two limiting rods forms the aforementioned positioning groove 103. When the connecting part 201 is embedded in the positioning groove 103, both sides of the connecting part 201 abut against the two limiting rods. Thus, during adjustment, the connecting part 201 can move up and down in contact with the positioning groove 103, ensuring the stability of the adjustment. Of course, in other embodiments, the positioning groove 103 can also be a recess provided on the mounting plate 102.

[0061] In this embodiment, the support 202 is also provided with a second adjustment structure 5 for adjusting the axial distance of the torque meter 6 relative to the shaft of the motor 3. The torque meter 6 can be finely adjusted in the axial direction through the second adjustment structure 5, thereby realizing the coaxial connection of the torque meter 6 with the motor shaft and the pump shaft, and adapting to the testing of motors 3 and water pumps of different specifications.

[0062] For details, see Figure 1 and Figure 3The second adjustment structure 5 includes a second adjustment hole 501 and a bolt assembly 502. The second adjustment hole 501 is a strip-shaped hole located on the support part 202 and extending axially. The bolt assembly 502 includes a second locking bolt and a locking nut. During installation, align the mounting hole on the base plate of the torque meter 6 with the second adjustment hole 501. Then, pass the shank of the second locking bolt through the mounting hole and the second adjustment hole 501, and then screw on the locking nut. At this point, the head of the second locking bolt and the locking nut are distributed on the upper and lower sides of the second adjustment hole 501. Tightening the locking nut secures the torque meter 6 and the adjustable support plate 2. When it is necessary to adjust the axial position of the torque meter 6, loosen the locking nut and then move the torque meter 6 axially along the second adjustment hole 501. Once the axial position of the torque meter 6 is adjusted to the correct position, tighten the locking nut. Thus, the axial position of the torque meter 6 can be adjusted through the second adjustment structure 5 to accommodate motors and pumps of different sizes and specifications, providing greater versatility.

[0063] Further, see Figure 1 Two sets of the second adjustment structure 5 are provided. These two sets of second adjustment structures 5 can improve the connection stability between the torque meter 6 and the adjustable support plate 2, thereby improving the support stability of the torque meter 6. Furthermore, the two sets of second adjustment structures 5 are symmetrically arranged with respect to the rotating shaft of the motor 3, and the bottom mounting holes of the torque meter 6 are usually symmetrically arranged with respect to the torque axis of the torque meter 6. Thus, when the torque meter 6 is installed on the adjustable support plate 2 through these two sets of second adjustment structures 5, the torque axis of the torque meter 6 and the rotating shaft of the motor 3 are exactly on the same vertical plane. This allows for centering adjustment of the torque axis and the rotating shaft simply by adjusting the support height of the adjustable support plate 2, making the operation much simpler.

[0064] See Figure 3 In this embodiment, a reinforcing rib 7 is fixedly connected between the connecting part 201 and the supporting part 202. The reinforcing rib 7 is vertically arranged and perpendicular to both the connecting part 201 and the supporting part 202, and is located in the middle of the connecting part 201 and the supporting part 202. In this way, the reinforcing rib 7 can strengthen the overall structural strength of the adjustable support plate 2 and improve the support stability of the torque meter 6.

[0065] On the other hand, this embodiment of the invention also provides a torque detection device, see [link to relevant documentation]. Figure 4 The torque detection device includes: a motor 3, a torque meter 6, and an adjustable torque meter bracket in any of the above embodiments.

[0066] The torque meter adjustable bracket transition connection 1 is installed on the housing of the motor 3, and the torque meter 6 is installed on the adjustable support plate 2 of the torque meter adjustable bracket.

[0067] When using this torque testing device for torque testing, first place the device to be tested (such as a water pump) in a position opposite to the motor 3, and align the pump shaft with the motor shaft. Then, adjust the height of the torque meter 6 using the adjustable bracket to make the torque shaft coaxial with the pump shaft and motor shaft. Next, adjust the axial position of the torque meter 6 so that the torque shaft can be coaxially connected to the pump shaft and motor shaft via a coupling. After installation, the test can be performed.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
