[0035] To make the objectives, technical solutions and advantages of this application clearer, the following will clearly and completely describe the technical solutions in this application and how the technical solutions in this application solve the above technical problems by using specific embodiments in combination with the accompanying drawings in this application. Obviously, the described embodiments are some but not all of the embodiments of this application. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0036] In the description of the specification, claims and the above accompanying drawings of this application, the terms "first", "second", "third", "fourth", etc. (if any) are used to distinguish similar objects and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0037] In the embodiments of this application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" aims to present relevant concepts in a specific manner.

[0038] In the related art, a ventilator generally includes a housing, a motor, an impeller, etc. The motor is fixed inside the housing through a base, and the impeller is fixed on the output shaft of the motor. During the actual installation of the motor, first fix the base inside the housing through bolts, and then fix the motor on the base through bolts. At this time, in order to ensure the normal operation of the ventilator and prevent mutual wear between the impeller and the housing, alignment of the motor is performed to make the output shaft of the motor in the central position of the housing.

[0039] However, the traditional alignment method is to use a steel ruler to measure the position between the output shaft of the motor and the housing multiple times to find the central position of the housing; or after fixing the impeller on the motor, move the motor multiple times to calibrate the impeller so that the impeller and the output shaft of the motor are in the central position of the housing. As a result, the operation process of the traditional alignment method is complicated, time-consuming and laborious, increasing the labor intensity.

[0040] Therefore, the embodiment of the present application provides an alignment device for motor installation. By setting an alignment member and a connecting member on the alignment member; when the motor is placed on the installation surface inside the housing and then the motor is aligned, only need to connect the connecting member to the output shaft of the motor, and make the axis direction of the alignment member and the axis direction of the output shaft form an included angle; secondly, rotate the output shaft of the motor so that the output shaft drives the alignment member to rotate inside the housing. At this time, as long as it is ensured that when the alignment member is in at least three different positions, the distances between the output shaft and the housing at each position are equal, the output shaft can be positioned at the central position of the housing, and the alignment step of the motor can be completed more conveniently, solving the problem of inconvenient alignment of the motor during the installation of the ventilator in the prior art.

[0041] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0042] As Figure 1 and Figure 2 shown, the embodiment of the present application provides an alignment device for motor installation, including an alignment member 100 and a connecting member 200; the connecting member 200 is arranged on the alignment member 100, and the connecting member 200 is also used for detachably arranging on the output shaft 20 of the motor 10, and making the axis direction of the alignment member 100 and the axis direction of the output shaft 20 form an included angle; the alignment member 100 is configured to drive the alignment member 100 to rotate inside the housing 30 through the output shaft 20 when the motor 10 is arranged on the installation surface, and ensure that when the alignment member 100 is in at least three different positions, the distances between the output shaft 20 and the housing 30 at each position are equal, so as to position the output shaft 20 at the central position of the housing 30.

[0043] In the embodiment of the present application, the connecting member 200 may be block-shaped, tubular, truncated cone-shaped or in other shapes, without limitation. A connecting groove is provided at one end of the connecting member 200 away from the alignment member 100, so that the connecting member 200 may be sleeved and fixed on the end of the output shaft 20. Of course, a clamp or a buckle may also be provided on the connecting member 200, so that the connecting member 200 may be clamped and fixed on the output shaft 20 by means of the clamp or the buckle.

[0044] When the motor 10 is placed on the mounting surface on the inner side of the casing 30, when the motor 10 is subsequently aligned, it is only necessary to fix the connecting piece 200 on the output shaft 20 of the motor 10, and make the axial direction of the aligning piece 100 form an angle with the axial direction of the output shaft 20; secondly, rotate the output shaft 20 of the motor 10 so that the output shaft 20 drives the aligning piece 100 to rotate inside the casing 30. At this time, it is only necessary to ensure that when the aligning piece 100 is in at least three different positions, the distance between the output shaft 20 and the casing 30 at each position is equal, thereby positioning the output shaft 20 at the center of the casing 30, and completing the alignment step of the motor 10 more conveniently, thereby solving the problem of inconvenience in aligning the motor 10 when installing the fan in the prior art.

[0045] like Figure 2 As shown, in some embodiments, the alignment member 100 includes a main rod 110 and a connecting portion 120, the main rod 110 is threadedly connected to the connecting portion 120, and the connecting member 200 is connected to the connecting portion 120; when the connecting member 200 is arranged on the output shaft 20, the axial direction of the main rod 110 is arranged at an angle to the axial direction of the output shaft 20.

[0046] In the embodiment of the present application, the connecting portion 120 can be fixed to the connecting member 200 by welding, screwing, bonding or other methods. After the alignment member 100 is fixed to the end of the output shaft 20 through the connecting member 200, preferably, the axis direction of the main rod 110 is perpendicular to the axis direction of the output shaft 20.

[0047] In addition, during the installation process, rotating the main rod 110 will also cause the main rod 110 to move relative to the connecting piece 200, thereby adjusting the length of the main rod 110 extending toward the housing 30 to adapt to housings 30 of different diameters and improve the applicability of the alignment device.

[0048] In other embodiments, the angle between the axial direction of the main rod 110 and the axial direction of the output shaft 20 can be set to other sizes; the main rod 110 can also be set to other shapes, such as tubular or irregular, without limitation, so that the main rod 110 can indicate the distance between the output shaft 20 and the housing 30.

[0049] like Figure 2As shown, in some embodiments, the main rod 110 penetrates through the connecting portion 120. A first limiting member 111 and a second limiting member 112 are provided on the main rod 110, and the first limiting member 111 and the second limiting member 112 are respectively arranged on both sides of the connecting portion 120.

[0050] Specifically, one end of the main rod 110 penetrates through the connecting portion 120, and the main rod 110 is in threaded connection with the connecting portion 120, so that rotating the main rod 110 can make the main rod 110 move relatively stably with respect to the connecting portion 120. At this time, the first limiting member 111 and the second limiting member 112 are respectively arranged on both sides of the connecting portion 120, so that when the main rod 110 moves relative to the connecting portion 120, the first limiting member 111 and the second limiting member 112 can respectively limit the moving amount of the main rod 110 from both sides of the connecting portion 120, reducing the possibility that the main rod 110 completely disengages from the connecting portion 120.

[0051] As Figure 2 shown, further, at least one of the first limiting member 111 and the second limiting member 112 is in threaded connection with the main rod 110 and is detachably arranged relative to the main rod 110.

[0052] In the embodiments of the present application, the first limiting member 111 and the second limiting member 112 can both be set in a block shape, a tubular shape or other shapes, or can also be set as nuts, and no limitation is made thereto.

[0053] The first limiting member 111 is fixed on the main rod 110, and the first limiting member 111 can be fixed on the main rod 110 by welding, bonding, clamping or other means, and no limitation is made thereto.

[0054] The second limiting member 112 has a threaded through hole inside, so that the second limiting member 112 is sleeved on the main rod 110 and is in threaded connection with the main rod 110. Furthermore, rotating the second limiting member 112 can also adjust the distance between the first limiting member 111 and the second limiting member 112, thereby adjusting the moving range of the main rod 110 on the connecting portion 120.

[0055] During actual production, for example, the end of a rod can be welded and fixed to the screw head of a bolt (the bolt includes an integrally formed screw head and a screw rod), so that the rod is located on the side of the screw head away from the screw rod and is coaxial with the screw rod. Secondly, two nuts are commonly threaded on the screw rod. Thus, the rod and the screw rod together form the main rod 110, the screw head is the first limiting member 111, the nut close to the screw head is the connecting portion 120, and the nut far from the screw head is the second limiting member 112. Finally, the connecting portion 120 is fixed to the connecting member 200.

[0056] In other embodiments, the first limiting member 111 and the second limiting member 112 can also be threadedly connected to the main rod 110, so that during use, the first limiting member 111 and the second limiting member 112 can jointly clamp the connecting portion 120, thereby making it difficult for the main rod 110 to shift relative to the connecting portion 120 during the rotation of the output shaft 20, ensuring the accuracy of the alignment of the motor 10.

[0057] As Figure 2 and Figure 3 shown, in some embodiments, a contact rod 300 is slidably arranged on the main rod 110 along the axis direction of the main rod 110, and one end of the contact rod 300 far from the main rod 110 is used to abut against the inner wall of the housing 30; an indicating member is arranged on the contact rod 300, so that the contact rod 300 can conspicuously indicate the relative position between the contact rod 300 and the main rod 110 through the indicating member.

[0058] In the embodiment of the present application, the axis direction of the contact rod 300 is parallel to the axis direction of the main rod 110, and the contact rod 300 is slidably arranged on the main rod 110, so that by sliding the contact rod 300, one end of the contact rod 300 far from the main rod 110 can abut against the inner wall of the housing 30. Subsequently, when the current position is indicated by the indicating member, the relative position between the contact rod 300 and the main rod 110 is shown.

[0059] During use, when the motor 10 is installed on the installation surface inside the housing 30 and the output shaft 20 is rotated, the main rod 110 and the contact rod 300 will synchronously sweep inside the housing 30, and when the main rod 110 is in at least three different positions, the contact rod 300 is in contact with the inner wall of the housing 30. At this time, only by observing the jump amount of the contact rod 300 relative to the main rod 110 when the main rod 110 is in each different position through the indicating member, if the contact rod 300 does not move relative to the main rod 110 or the moving distance is within the allowable range, it can be indicated that the output shaft 20 is in the central position of the housing 30, making the alignment process of the motor 10 more convenient.

[0060] In other embodiments, if it is necessary to improve the stability of the contact rod 300 when moving relative to the main rod 110, a plurality of support portions can also be arranged on the main rod 110, so that the contact rod 300 passes through the support portions, and then the movement of the contact rod 300 is supported and limited by the support portions to ensure the stability of the contact rod 300 during the movement.

[0061] As Figure 3 shown, in some embodiments, the indicating member is a pointer 400, and the main rod 110 is provided with scales 500 distributed along the axis direction of the main rod 110, and the pointer 400 is correspondingly arranged in the area where the scales 500 are located to indicate the relative position between the contact rod 300 and the main rod 110.

[0062] Among them, the pointer 400 can be arranged at one end of the contact rod 300 facing the main rod 110 by welding, bonding or integrally forming with the contact rod 300. The scale 500 can be engraved on the outer wall of the main rod 110 or coated on the outer wall of the main rod 110.

[0063] When the main rod 110 and the contact rod 300 jointly sweep inside the housing 30, only the jumping situation of the pointer 400 in the area where the scale 500 is located needs to be observed, making the jumping situation of the pointer 400 more prominent and reducing the operation difficulty in the alignment process of the motor 10.

[0064] In other embodiments, the indicating member can also be set as a color pattern coated on the contact rod 300, and the color pattern includes a variety of different color areas distributed along the moving direction of the contact rod 300; at this time, an observation hole corresponding to the color pattern is opened on the main rod 110. Thus, it is convenient to observe the jumping situation of the color pattern from the observation hole, so as to know the jumping situation of the contact rod 300 more prominently.

[0065] As Figure 3 shown, in some embodiments, the contact rod 300 is provided with a traction spring 600. Two ends of the traction spring 600 are respectively connected to the main rod 110 and the contact rod 300, and the traction spring 600 is used to make the contact rod 300 have a tendency to slide away from the main rod 110.

[0066] Specifically, the traction spring 600 is coaxially sleeved on the contact rod 300. One end of the traction spring 600 is fixed to the contact rod 300 by welding, bonding or other means, and the other end is fixed to the main rod 110 by welding, bonding or other means, and there is no limitation on this.

[0067] During use, the initial position of the whole alignment device is that after the contact rod 300 is compressed by a certain distance first, and then the connecting member 200 is fixed on the output shaft 20, so that the contact rod 300 will, under the action of the traction spring 600, keep having a tendency to move towards the housing 30. Furthermore, during the process of rotating the output shaft 20, the contact rod 300 will keep contacting the inner wall of the housing 30, so that only the jumping situation of the pointer 400 in the area of the scale 500 needs to be observed, and the accuracy of the jumping of the pointer 400 is higher.

[0068] As Figure 3 shown, further, a roller 310 is arranged at one end of the contact rod 300 away from the main rod 110, and the roller 310 is used to contact the housing 30.

[0069] Thus, during the process of the contact rod 300 and the main rod 110 sweeping, the contact rod 300 contacts the housing 30 through the roller 310, thereby reducing the possibility of causing wear to the housing 30.

[0070] AsFigure 3 and Figure 4 As shown, in some embodiments, the interior of the main rod 110 is a hollow structure, and the contact rod 300 is coaxially inserted inside the main rod 110, so that one end of the contact rod 300 is located on the inner side of the main rod 110, and the other end extends to the outside of the main rod 110 and is used to contact the housing 30; a stud 700 is provided at one end of the contact rod 300 away from the main rod 110, and the stud 700 is used to be threadedly connected to the end of the main rod 110 facing the contact rod 300.

[0071] Specifically, the main rod 110 is hollow inside and has an opening at one end, so that the contact rod 300 can be coaxially inserted into the main rod 110 from the open end of the main rod 110, so that the contact rod 300 is slidably connected relative to the main rod 110. At this time, the traction spring 600 is arranged inside the main rod 110, thereby having a better protective effect on the traction spring 600.

[0072] At this time, the side wall of the main rod 110 is provided with an avoidance hole extending along its length direction, and the pointer 400 is embedded in the avoidance hole, so that when the contact rod 300 moves relative to the main rod 110, the pointer 400 will move in the avoidance hole, and the scale 500 is located at the edge of the avoidance hole.

[0073] The stud 700 is disposed at one end of the contact rod 300 away from the pointer 400 , and an internal thread is disposed inside the opening edge of the main rod 110 , so that the stud 700 can be threadedly fitted in the opening end of the main rod 110 .

[0074] When in use, the main rod 110 has a better supporting effect on the contact rod 300 during the extension and retraction process of the contact rod 300, so that the stability of the contact rod 300 during the extension and retraction process is better. In addition, when the alignment device is not used, the contact rod 300 can be retracted as a whole to the inside of the main rod 110, and then the stud 700 is matched with the open end of the main rod 110, thereby locking the contact rod 300 inside the main rod 110. In the storage process, the main rod 110 has a better protective effect on the contact rod 300, which can reduce the possibility of the contact rod 300 being affected by external forces and extend the service life.

[0075] like Figure 4 As shown, in some embodiments, a baffle 710 is provided at one end of the contact rod 300 away from the main rod 110, a through hole is provided in the middle of the stud 700, the stud 700 is coaxially sleeved and rotatably set on the contact rod 300, and the stud is located on the side of the baffle 710 away from the main rod 110.

[0076] Among them, the baffle 710 can be fixed to one end of the contact rod 300 away from the pointer 400 by bonding, welding, screwing or other means. The middle of the stud 700 has a through hole, so that the stud 700 can be coaxially sleeved on the contact rod 300 and can rotate relative to the contact rod 300. The stud 700 is also located on the side of the baffle 710 away from the pointer 400.

[0077] When the stud 700 is fitted to the open end of the main rod 110, the stud 700 will block the contact rod 300 through the baffle 710 to ensure the stability of the contact rod 300 after being received inside the main rod 110. Moreover, the stud 700 can rotate relative to the contact rod 300. Thus, when the stud 700 is fitted to the opening of the main rod 110, the stud 700 is not likely to interfere with the contact rod 300 and there is no need for the contact rod 300 to rotate.

[0078] In summary, the embodiment of the present application provides an alignment device for motor installation. When the motor 10 is placed on the installation surface inside the machine shell 30 and then the alignment of the motor 10 is carried out, only the connecting member 200 needs to be fixed on the output shaft 20 of the motor 10, and the axis direction of the alignment member 100 is set at an angle with the axis direction of the output shaft 20. Secondly, rotate the output shaft 20 of the motor 10 so that the output shaft 20 drives the alignment member 100 to rotate inside the machine shell 30. At this time, it only needs to ensure that when the alignment member 100 is in at least three different positions, the distance between the output shaft 20 and the machine shell 30 at each position is equal, so as to position the output shaft 20 at the center position of the machine shell 30, and the alignment step of the motor 10 can be completed more conveniently, solving the problem of inconvenient alignment of the motor 10 during the installation of the ventilator in the prior art.
