Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor position regulating device. Background Art

[0002] A motor base is a component used to support and secure the motor in place. It is typically made of aluminum alloy, cast iron, or steel. In industrial and mechanical equipment, the base stabilizes the motor, preventing it from shaking during operation, thereby ensuring safe and stable operation. Furthermore, the heavy base offers excellent sound absorption and vibration dampening capabilities, providing vibration isolation and noise reduction, effectively controlling the noise and vibration generated by the motor during operation.

[0003] However, when the motor position deviates and needs to be adjusted, the motor support base carrying the large motor equipment will be very heavy, making it difficult to adjust the position and unable to accurately correct the motor position.

[0004] In view of the above shortcomings, it is necessary to design a motor position adjustment device. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is that it is difficult to accurately calibrate the position of the motor because the motor supporting base on which the motor is installed is very heavy, so a motor position adjustment device is provided.

[0006] In order to solve the above technical problems, the technical solutions of the present utility model are as follows:

[0007] A motor position adjustment device, comprising:

[0010] A guide rail is located between the base and the motor bearing plate, and the guide rail is slidably engaged with the slide groove;

[0011] The screw assembly includes a screw located below the motor bearing plate, the length direction of the screw is parallel to the length direction of the slide groove, one end of the screw is the driving end, and the other end is threadedly connected to the through hole in the screw connecting block.

[0012] Furthermore, the guide rail and the slide groove are both one.

[0013] Furthermore, it also includes a first support block fixedly connected to the base, the first support block is located on the side of the screw rod facing away from the guide rail, and the first support block is used to support the corresponding side of the motor bearing plate.

[0014] Furthermore, it also includes a second support block arranged at a relative distance from the first support block, the second support block is fixedly connected to the base and is located on the side of the screw rod facing the guide rail, and the second support block is used to support the corresponding side on the motor bearing plate.

[0015] Furthermore, the motor supporting plate is respectively provided with a first limiting hole and a second limiting hole corresponding to the first supporting block and the second supporting block, and the motor position adjustment device also includes a first limiting member corresponding to the first limiting hole and a second limiting member corresponding to the second limiting hole. The first supporting block and the second supporting block are collectively referred to as support blocks, the first limiting hole and the second limiting hole are collectively referred to as limiting holes, the first limiting member and the second limiting member are collectively referred to as limiting members, the bottom end of the limiting member passes through the limiting hole and is fixedly connected to the corresponding support block, and the top end protrudes from the top surface of the motor supporting plate. In the width direction of the limiting hole, the size of the top end of the limiting member is larger than the size of the limiting hole.

[0016] Furthermore, the two limiting holes are waist-shaped holes parallel to each other, and the length direction of the limiting holes is parallel to the length direction of the sliding groove.

[0017] Furthermore, it also includes a screw bearing and a screw bearing seat fixedly connected to the base, and one end of the screw away from the screw connecting block is installed on the screw bearing seat through the screw bearing.

[0018] Furthermore, it also includes a bearing seat connecting plate fixed on the top surface of the base, and the screw bearing seat is fixed on the top surface of the bearing seat connecting plate.

[0019] Furthermore, it also includes a first connecting plate and a second connecting plate arranged at a relative distance from each other, the first connecting plate and the second connecting plate are both fixed on the top surface of the base, the first support block is fixed on the top surface of the first connecting plate, and the guide rail and the second support block are fixed on the top surface of the second connecting plate.

[0020] Furthermore, the vertical spacing between the screw bearing seat and the bearing seat connecting plate is adjusted by a high-strength bolt, and the high-strength bolt passes through the bearing seat threaded hole in the screw bearing seat from top to bottom and enters the connecting plate groove in the bearing seat connecting plate.

[0021] The technical solution of this utility model has the following advantages:

[0022] 1. The motor position adjustment device provided by the present invention has one end of the screw as the driving end and the other end threadedly connected to the screw connecting block, which is fixedly connected to the motor supporting plate. In this way, when the screw driving member drives the screw to rotate, the entire motor supporting plate and the motor mounted on the motor supporting plate will be driven by the screw connecting block to move along the length direction of the screw, thereby adjusting the motor position to a suitable position and achieving correction of the motor position. In addition, the sliding cooperation between the guide rail and the slide groove can well guide the movement of the motor supporting plate along the length direction parallel to the screw, thereby improving the adjustment efficiency of the motor position and reducing the risk of damage to the screw due to the movement trajectory of the motor deviating from the length direction parallel to the screw. In addition, because the screw and the screw connecting block are located below the motor supporting plate, the risk of dust entering between the screw and the screw connecting block is reduced, and the service life of the screw is extended. Furthermore, the movement of the motor supporting plate by the rotation of the screw is more convenient than the traditional method of moving large equipment. The overall installation of the adjustment device is simple, the required space is limited, and the position adjustment accuracy is high.

[0023] 2. The motor position adjustment device provided by the present invention has one guide rail and one slide groove. Compared with the design of two guide rails and two slide grooves, the requirements for the parallelism of the guide rails can be reduced, which helps to save the installation time of large components and reduce component costs.

[0024] 3. The motor position adjustment device provided by the utility model also includes a first support block fixedly connected to the base, the first support block is located on the side of the screw rod facing away from the guide rail, the first support block is used to support the corresponding side of the motor bearing plate, the first support block cooperates with the guide rail to support the motor bearing plate, which can make the supporting force on the motor bearing plate more balanced, and at the same time, because the first support block can share the pressure of the motor and the motor bearing plate on the guide rail, it can reduce the friction between the slide groove and the guide rail, thereby increasing the service life of the guide rail.

[0025] 4. The motor position adjustment device provided by the utility model comprises a first limiting hole and a second limiting hole respectively opened on the motor supporting plate corresponding to the first support block and the second support block, the adjustment device also includes a first limiting member corresponding to the first limiting hole and a second limiting member corresponding to the second limiting hole, the first support block and the second support block are collectively referred to as the support block, the first limiting hole and the second limiting hole are collectively referred to as the limiting hole, the first limiting member and the second limiting member are collectively referred to as the limiting member, the bottom end of the limiting member passes through the limiting hole and is fixedly connected to the corresponding support block, and the top end protrudes from the top surface of the motor supporting plate, and in the width direction of the limiting hole, the size of the top end of the limiting member is larger than the size of the limiting hole. In this way, although the motor supporting plate will vibrate vertically when the motor is working, the top end of the limiting member will generate a downward restraining force on the motor supporting plate, and the bottom end of the limiting member is fixedly connected to the support block, thereby preventing the guide rail from deviating from the slide slot or even detaching from the slide slot, causing damage to the guide rail and / or slide slot.

[0026] 5. The motor position adjustment device provided by the present invention has two limiting holes which are parallel waist-shaped holes, and the length direction of the limiting holes is parallel to the length direction of the slide groove. The waist-shaped limiting holes are convenient for processing on the one hand, and can guide the movement of the motor supporting plate to a certain extent on the other hand.

[0027] 6. The motor position adjustment device provided by the utility model also includes a screw bearing and a screw bearing seat fixedly connected to the base. The end of the screw away from the screw connecting block is installed on the screw bearing seat through the screw bearing. The provision of the screw bearing seat and the screw bearing helps the screw to withstand greater radial and axial loads, and prevents the screw from breaking due to excessive weight of the motor equipment.

[0028] 7. The motor position adjustment device provided by the utility model, the vertical spacing between the screw bearing seat and the bearing seat connecting plate is adjusted by a high-strength bolt, and the high-strength bolt passes through the bearing seat threaded hole in the screw bearing seat from top to bottom and enters the connecting plate groove in the bearing seat connecting plate. In this way, as the high-strength bolt moves downward relative to the bearing seat threaded hole on the screw bearing seat, the bottom end of the high-strength bolt will continuously increase the abutment force on the bottom of the connecting plate groove, so that the vertical spacing between the two slowly increases, and finally the vertical spacing between the bearing seat connecting plate and the screw bearing seat is adjusted, and after ensuring that the screw hole on the screw bearing seat is coaxial with the through hole on the screw connecting block, the screw bearing seat and the bearing seat connecting plate are locked together with a locking bolt, thereby preventing the screw from being damaged due to poor coaxiality between the screw hole on the screw bearing seat and the through hole on the screw connecting block.

[0040] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0041] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0043] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] like Figures 1 to 8 As shown, the present invention provides a motor position adjustment device (hereinafter referred to as the adjustment device), which is particularly suitable for position adjustment of large motors, including a base 1, a motor carrier plate 2, a guide rail 3, and a screw assembly 4. The motor carrier plate 2 is arranged above the base 1, and a screw connecting block 20 and a guide rail mounting block 22 are fixedly provided at the bottom of the motor carrier plate 2. The screw connecting block 20 is located on the inner side of the guide rail mounting block 22, and a slide groove 221 (such as Figure 7 (as shown). Guide rail 3 is located between base 1 and motor carrier plate 2, and slides in engagement with slideway 221. Screw assembly 4 includes a screw 41 located below the motor carrier plate. Screw 41 is rotatable about its own axis, with its length parallel to the length of slideway 221. One end of screw 41 is a driving end, and the other end is threadedly connected to a through hole (unnumbered) in screw connecting block 20.

[0045] In the present invention, since one end of the screw rod 41 is the driving end, external force acting on the driving end can drive the screw rod to rotate, and the other end is threadedly connected to the through hole in the screw rod connecting block 20, and the screw rod connecting block 20 is fixedly connected to the motor supporting plate 2. In this way, when the screw rod 41 is driven to rotate by external force, the entire motor supporting plate 2 and the motor 7 installed on the motor supporting plate 2 will be driven through the screw rod connecting block 20 to move along the length direction of the screw rod 41, thereby moving the position of the motor 7 and adjusting it to a suitable position to achieve correction of the motor position. In addition, through the sliding cooperation between the guide rail 3 and the slide groove 221, the motor supporting plate 2 can be well guided to move along the length direction parallel to the screw rod 41, so as to improve the adjustment efficiency of the motor 7 position, and at the same time, it can also reduce the risk of damaging the screw rod 41 due to the movement trajectory of the motor 7 deviating from the length direction parallel to the screw rod 41. In addition, because the screw rod 41 and the screw rod connecting block 20 are located below the motor supporting plate 2, the risk of dust entering between the screw rod 41 and the screw rod connecting block 20 is reduced, thereby extending the service life of the screw rod 41. Furthermore, the movement of the motor supporting plate 2 by the rotation of the screw rod 41 is more convenient than the traditional method of moving large equipment. The overall installation of the adjustment device is simple, the required space is limited, and the position adjustment accuracy is high.

[0046] The screw rod 41 can be driven by hand or by handwheel. In the present embodiment, the screw rod 41 is hand-cranked. When in use, the driving end of the screw rod 41 (i.e., the end of the screw rod 41) is clamped with an adjustable wrench and the screw rod 41 is driven to rotate around its own axis by hand-cranking.

[0047] In this embodiment, the base 1 is a plate-shaped structure. The motor bearing plate 2 is usually made of aluminum alloy, cast iron or steel.

[0048] Furthermore, the guide rail 3 and the slide groove 221 are both one, which can reduce the requirements for the parallelism of the guide rail 3 compared to the design of two guide rails 3 and two slide grooves 221, help save the installation time of large components, and reduce component costs.

[0049] Furthermore, the slide groove 221 is a dovetail groove, which helps to quickly position the slide groove 221 and the guide rail 3, thereby improving assembly efficiency.

[0050] Furthermore, the motor position adjustment device also includes two first support blocks 51 fixedly connected to the base 1. The first support block 51 is located on the side of the screw rod 41 facing away from the guide rail 3. The first support block 51 is used to support one side of the motor carrier plate 2. The first support block 51 cooperates with the guide rail 3 to support the motor carrier plate 2, which can make the support force on the motor carrier plate 2 more balanced. At the same time, because the first support block 51 can share the pressure of the motor 7 and the motor carrier plate 2 on the guide rail 3, the friction between the chute 221 and the guide rail 3 can be reduced, thereby improving the service life of the guide rail 3. The two first support blocks 51 are arranged at intervals along the length direction parallel to the chute 221. Of course, only one first support block 51 can be provided, or even more.

[0051] Furthermore, the motor position adjustment device also includes two second support blocks 52 arranged at a relative distance from the first support block 51. The second support block 52 is fixedly connected to the base 1 and is located on the side of the screw rod 41 facing the guide rail 3. The second support block 52 is used to support the other side of the motor carrier plate 2. In this embodiment, the second support block 52 is located on the outside of the guide rail 3 and cooperates with the guide rail 3 to support the corresponding side of the motor carrier plate 2. In other embodiments, the second support block 52 is located on the inside of the guide rail 3 and is located between the guide rail 3 and the screw rod 41. The two second support blocks 52 are arranged at a distance along the length direction parallel to the slide groove 221. The thickness of the first support block 51 is the same as the thickness of the second support block 52. Of course, only one first support block 51 can be provided, or even more.

[0052] Furthermore, the motor carrier plate 2 is provided with a first limiting hole 21a and a second limiting hole 21b corresponding to the first support block 51 and the second support block 52, respectively. The motor position adjustment device further includes a first limiting member corresponding to the first limiting hole 21a and a second limiting member corresponding to the second limiting hole 21b. The first support block 51 and the second support block 52 are collectively referred to as support blocks, the first limiting hole 21a and the second limiting hole 21b are collectively referred to as limiting holes 21, the first limiting member and the second limiting member are collectively referred to as limiting members, the bottom end of the limiting member passes through the limiting hole 21 and is fixedly connected to the corresponding support block, and the top end protrudes from the top surface of the motor carrier plate 2, in the width direction of the limiting hole 21 (such as Figure 1In the direction indicated by the middle arrow), the size of the top of the limit member is larger than the size of the limit hole 21. In this way, although the motor support plate 2 will vibrate vertically when the motor 7 is working, the top of the limit member will exert a downward restraining force on the motor support plate 2. At the same time, the bottom end of the limit member is fixedly connected to the support block. In addition, the two opposite sides of the width direction of the limit hole 21 cooperate with the limit member to limit the motor support plate 2 and the support block laterally on the base 1. Therefore, the guide rail 3 can be prevented from deviating from the slide groove 221 or even detaching from the slide groove 221, causing damage to the guide rail 3 and / or the slide groove 221. In this embodiment, each first support block 51 corresponds to a limit hole 21a and a first limit member, and each second support block 52 corresponds to a second limit hole 21b and a second limit member. In other embodiments, only one of the two first support blocks 51 can be provided with the first limit hole 21a and the first limit member, and only one of the two second support blocks 52 can be provided with the second limit hole 21b and the second limit member.

[0053] Furthermore, the limiting hole 21 is a waist-shaped hole, and the length direction of the limiting hole 21 is parallel to the length direction of the slide groove 221. The waist-shaped limiting hole 21 is convenient for processing on the one hand, and can also play a certain guiding role in the movement of the motor supporting plate 2 on the other hand. In this embodiment, the limiting member is a bolt, and a threaded hole 512 (such as Figure 6 As shown in FIG, the threaded hole 512 is vertically connected to the limiting hole 21. The bottom end of the bolt is threadedly connected to the threaded hole 512, and the top end protrudes from the top surface of the motor carrier plate 2. The length of the limiting hole 21 is not less than the sliding stroke of the chute 221 along the guide rail 3. Preferably, the length of the limiting hole 21 is equivalent to the sliding stroke of the chute 221 along the guide rail 3. In this way, on the one hand, the limiting member can vertically limit the motor carrier plate 2, and on the other hand, it can prevent the chute 221 from sliding excessively relative to the guide rail 3 and detaching from the guide rail 3, thereby causing damage to the motor 7 or personal injury. In other embodiments, the limiting holes 21 can also be a plurality of round through holes spaced apart along the length direction of the guide rail 3.

[0054] Further, if Figure 1 、 Figure 2 、 Figure 3 and Figure 8As shown, the screw assembly 4 also includes a screw bearing seat 42 fixedly connected to the base 1, and a screw bearing 43. The end of the screw 41 away from the screw connecting block 20 is installed in the screw hole on the screw bearing seat 42 through the screw bearing 43. In this embodiment, there are two screw bearings 43, and a gasket (not marked) is provided between the two screw bearings 43. In this embodiment, the provision of the screw bearing seat 42 and the screw bearing 43 helps the screw 41 withstand greater radial and axial loads and prevents the screw 41 from breaking due to the excessive weight of the motor equipment. The screw assembly 4 also includes a nut 44 and an end cap 45. The nut 44 is threadedly connected to the screw 41 and is located outside the screw bearing 43 to prevent the screw bearing 43 from detaching from the screw 41. The end cap 45 is sleeved on the screw 41, located outside the nut 44, and covers the nut 44 toward the end of the screw 41 connected to the screw connecting block 20. The end cap 45 is also fixed to the screw bearing seat 42 by bolts.

[0055] Furthermore, the motor position adjustment device further includes a bearing seat connecting plate 46 fixed on the top surface of the base 1. Figure 2 and Figure 3 As shown, the vertical spacing between the bearing seat connecting plate 46 and the screw bearing seat 42 is adjusted by a high-strength bolt (not shown). Specifically, the high-strength bolt passes through the bearing seat threaded hole 421 on the screw bearing seat 42 from top to bottom. As the high-strength bolt moves downward relative to the bearing seat threaded hole 421 on the screw bearing seat 42, the bottom end of the high-strength bolt will continuously increase the abutment force on the bottom of the groove 461 of the connecting plate, so that the vertical spacing between the two is gradually increased, and finally the vertical spacing between the bearing seat connecting plate 46 and the screw bearing seat 42 is achieved. To adjust the spacing, after the screw hole on the screw bearing seat 42 is coaxial with the through hole on the screw connecting block 20, use a locking bolt (not shown, different from the aforementioned high-strength bolt) to pass from bottom to top through the connecting plate threaded hole 462 on the bearing seat connecting plate 46 and the bearing seat through hole 422 on the screw bearing seat 42, and then use a nut to lock the bearing seat connecting plate 46 and the screw bearing seat 42 together, thereby preventing the screw 41 from being damaged due to poor coaxiality between the screw hole on the screw bearing seat 42 and the through hole on the screw connecting block 20.

[0056] Furthermore, the motor position adjustment device also includes a first connecting plate 61 and a second connecting plate 62 that are arranged at relative intervals. The first connecting plate 61 and the second connecting plate 62 are both fixed on the top surface of the base 1. The first support block 51 is fixed to the top surface of the first connecting plate 61 by bolts. The guide rail 3 and the second support block 52 are fixed to the top surface of the second connecting plate 62 by bolts, and the first connecting plate 61, the second connecting plate 62 and the bearing seat connecting plate 46 are all welded to the base 1.

[0057] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
