Description

Technical Field

[0001] The invention belongs to the technical field of DC motor installation, and particularly relates to an adjusting device for DC motor installation and an installation method thereof. Background Art

[0002] A DC motor is a motor that converts DC electrical energy into mechanical energy. When a DC power supply supplies power to the armature winding through carbon brushes, the conductors under the N pole on the armature surface can conduct current in the same direction. According to the left-hand rule, the conductors will be subjected to a counterclockwise torque; the conductors under the S pole on the armature surface also conduct current in the same direction, and according to the left-hand rule, the conductors will also be subjected to a counterclockwise torque. In this way, the entire armature winding, i.e., the rotor, will rotate counterclockwise, and the input DC electrical energy will be converted into mechanical energy output on the rotor shaft. DC motors are widely used in electric drives due to their good speed regulation performance. In actual installation of DC motors in the prior art, generally, the installation and fixation between the DC motor and the placement plane are achieved through a motor base. However, there is a deviation in the docking between the motor shaft of the DC motor and the coupling of the mechanical drive device, which affects the actual installation accuracy of the DC motor. Summary of the Invention

[0003] The purpose of the invention is to provide a technical solution for an adjusting device for DC motor installation and an installation method thereof aiming at the deficiencies of the prior art. Through the mutual cooperation of a fixed seat and an adjusting seat, the fixed seat supports and stabilizes the DC motor, and the adjusting seat can adjust the position of the fixed seat, thereby adjusting the position of the DC motor on the fixed seat, and further precisely adjusting the position of the motor shaft on the DC motor to ensure the precise positioning connection between the motor shaft and the coupling on the mechanical drive device, improving the installation accuracy. Moreover, the fixed seat and the adjusting seat are designed into a detachable structure. After the overall installation of the DC motor, the fixed seat is retained to ensure the overall installation firmness of the DC motor, while the adjusting seat is disassembled and assembled for recycling. The overall installation of the invention is convenient. First, the DC motor is pressed and limited on the fixed seat through a side pressing component, then the motor shaft is precisely positioned and clamped through a shaft supporting component, then the top of the DC motor is pressed and limited through a top pressing component, and then the position of the motor shaft is further adjusted in multiple directions of up and down, front and back, and left and right, so that the motor shaft is precisely positioned with the mechanical drive device, the motor shaft is connected with the mechanical drive device, and the DC motor is firmly fixed with the placement plane through a motor fixing frame. Finally, the adjusting seat is disassembled.

[0004] To solve the above technical problems, the invention adopts the following technical solutions:

[0005] A device for adjusting the installation of a DC motor, characterized in that it includes a fixed seat and an adjusting seat, the fixed seat is located on the adjusting seat, the fixed seat and the adjusting seat are detachably connected, the fixed seat includes a fixed base plate, a side pressure assembly and a top pressure assembly, the side pressure assembly is connected to the fixed base plate, the top pressure assembly is connected to the side pressure assembly, two left-right symmetrical positioning jacks are provided on the fixed base plate, the adjusting seat includes an adjusting base plate and a movable plate, the movable plate and the adjusting base plate are adjustably connected, the movable plate is located above the adjusting base plate, the fixed base plate is located on the top surface of the movable plate, and the fixed base plate and the movable plate are adjustably connected.

[0006] Furthermore, two side pressure assemblies are provided, and the two side pressure assemblies are symmetrically arranged on the top surface of the fixed base plate. The two side pressure assemblies each include a side plate, a buffer assembly and a side pressure plate. The side plate is fixedly connected to the fixed base plate, and the buffer assembly is evenly arranged on the side plate. The buffer assembly is fixed to the side plate through a limiter, and the side pressure plate is connected to the buffer assembly. The side pressure plate is located on the inner side of the side plate. Through the two side pressure assemblies symmetrically arranged, the left and right sides of the DC motor are simultaneously pressed and limited to ensure the stability of the DC motor on the fixed seat. The buffer assembly is connected to the side pressure plate. Due to the compressible design of the buffer assembly, the side pressure plate can be adjusted according to the actual width of the DC motor to ensure that the side pressure plate is pressed against the side of the DC motor to ensure the pressing effect of the side pressure plate on the DC motor.

[0007] Furthermore, heat dissipation slots are evenly arranged on the side panels, and the buffer assembly includes a limiting sleeve, a buffer compression spring and a support plate. The limiting sleeve matches the heat dissipation slot, and the limiting sleeve is movably clamped in the heat dissipation slot. One end of the buffer compression spring is located in the installation slot of the limiting sleeve, and the support plate is located at the other end of the buffer compression spring. The support plate is fixed to the side pressure plate with screws. The design of the heat dissipation slot can ensure the ventilation and heat dissipation effects on both sides of the DC motor. At the same time, the heat dissipation slot can facilitate the installation and limitation of the buffer assembly. The limiting sleeve cooperates with the heat dissipation slot to realize the initial clamping and limiting of the buffer assembly and the side panel, and the part of the buffer compression spring exposed in the limiting sleeve and the support plate extend through the heat dissipation slot to the inner side of the side panel, and then the support plate is fixed to the side pressure plate with screws. The overall disassembly and assembly is convenient and simple, and the design is reasonable.

[0008] Furthermore, the limiting member includes a limiting plate and a second set screw. A folding plate is provided at the end of the limiting sleeve. The folding plate is fixed to the limiting plate by screws. Limiting grooves are provided at both the front and rear ends of the side plate. Both the front and rear ends of the limiting plate are tightly abutted and limited against the side plate by the second set screw. The second set screw passes through the limiting plate and extends into the limiting groove. The limiting sleeve is fixed to the limiting plate by the folding plate at its end, ensuring the firm installation performance of the buffer assembly and the limiting plate. At the same time, the folding plate can play a limiting role. The width of the folding plate is greater than the width of the heat dissipation slot hole. When the limiting sleeve is inserted into the heat dissipation slot hole and the folding plate abuts against the outer side surface of the side plate, the limiting sleeve is inserted in place, facilitating the actual installation and positioning. The limiting plate itself is tightly abutted and limited against the side plate by the second set screw. Loosening the second set screw can adjust the vertical height of the limiting plate, thereby adjusting the installation height of the buffer assembly and further adjusting the vertical height of the side pressing plate, so that the side pressing plate can be appropriately adjusted according to the actual height of the DC motor, ensuring the pressing and limiting effect of the side pressing plate on the side of the DC motor. The design of the limiting groove can increase the contact area between the second set screw and the side plate, thereby improving the tightening effect of the second set screw.

[0009] Furthermore, the pressing component includes a positioning plate and a connecting rod. The connecting rods are symmetrically arranged on the left and right sides of the positioning plate. Guide sleeves are provided on the top surfaces of both the left and right side plates. The vertical section of the connecting rod matches the through groove on the guide sleeve. The vertical section of the connecting rod is inserted into the through groove, and the connecting rod is tightly abutted and limited against the guide sleeve by a third set screw. The connecting rod cooperates with the through groove to achieve the movable clamping connection between the positioning plate and the guide sleeve, and then the third set screw is used to tightly abut and limit the positioning plate and the guide sleeve, ensuring the connection stability between the two, thereby ensuring the pressing and limiting effect of the positioning plate on the top surface of the DC motor. Moreover, loosening the third set screw can adjust the vertical height of the positioning plate, enabling the positioning plate to be adjusted according to the actual height of the DC motor, ensuring the pressing and limiting effect of the positioning plate on the DC motor.

[0010] Furthermore, a shaft support assembly is provided on the front side of the fixed base plate. The shaft support assembly includes a lower support plate and an upper pressing plate. The lower support plate is fixedly connected to the fixed base plate. The upper pressing plate is connected to the lower support plate through an adjustment bolt. A limit perforation is provided on the upper pressing plate, and a threaded hole is provided on the lower support plate. Both the limit perforation and the threaded hole are matched with the adjustment bolt. The adjustment bolt passes through the limit perforation and is threadedly connected in the threaded hole. The motor shaft of the DC motor is supported and clamped by the shaft support assembly, improving the installation firmness between the DC motor and the fixed seat. The motor shaft is clamped and limited between the lower support plate and the upper pressing plate. Moreover, the connection between the lower support plate and the upper pressing plate is achieved through the ingenious design of the adjustment bolt. By adjusting the length of the bottom end of the adjustment bolt screwed into the threaded hole, the distance between the lower support plate and the upper pressing plate can be adjusted, thereby realizing the clamping support for motor shafts with different shaft diameters.

[0011] Furthermore, bumps are provided on the bottom surface of the fixed base plate. Dovetail-shaped chutes are provided on the bumps. Dovetail-shaped blocks are provided on the top surface of the movable flat plate. The dovetail-shaped blocks are matched with the dovetail-shaped chutes. The bumps are movably clamped on the dovetail-shaped blocks through the dovetail-shaped chutes. The bumps slide back and forth along the dovetail-shaped blocks, and the bumps are tightly limited against the dovetail-shaped blocks through the first set screws. Through the cooperation of the dovetail-shaped chutes and the dovetail-shaped blocks, the movable clamping connection between the fixed base plate and the movable flat plate is realized. Further, through the tight limiting of the first set screws, the clamping firmness between the fixed base plate and the movable flat plate is ensured. Moreover, the connection method of clamping can also facilitate the further adjustment of the position of the motor shaft in the subsequent process. The ingenious design of the dovetail shape can limit the up and down movement of the fixed base plate, improving the clamping stability between the fixed base plate and the movable flat plate, enabling the fixed base plate to only slide back and forth along the dovetail-shaped blocks, thereby realizing the adjustment of the front and back positions of the motor shaft. When the position needs to be adjusted, just loosen the first set screw, and the operation is convenient and simple.

[0012] Further, fixing blocks are provided at the four corners of the movable flat plate. The fixing blocks are fixed to the movable flat plate by screws. A perforation is provided on the fixing block, and a threaded rod is provided in the perforation. The threaded rod is limited and fixed to the fixing block by a limit nut. The limit nut is located on the upper and lower sides of the fixing block. Two adjacent threaded rods on the left and right are connected by a connecting plate. Connecting holes are provided at both ends of the connecting plate, and the connecting holes are matched with the threaded rods. The bottom end of the threaded rod is threadedly connected in the connecting hole. The overall structure is ingeniously and reasonably designed. The fixing block is movably sleeved on the threaded rod through the perforation, realizing the indirect connection between the movable flat plate and the threaded rod. Each fixing block is limited and fixed on the threaded rod by the clamping and limiting of the upper and lower limit nuts, ensuring the installation stability between the movable flat plate and the threaded rod. And by adjusting the position of the limit nut on the threaded rod, the position of the fixing block can be adjusted, so as to adjust the up and down height of the movable flat plate. The two threaded rods on the left and right are connected by a connecting plate. The connecting plate can cooperate with the adjusting bottom plate to realize the further clamping connection between the threaded rod and the adjusting bottom plate, facilitating the actual installation and positioning. Moreover, through the ingenious design of the connecting hole, the threaded connection between the threaded rod and the connecting plate is realized, ensuring the connection firmness between the threaded rod and the connecting plate, and this connection method is detachable, facilitating the actual assembly.

[0013] Further, adjusting bottom plates are provided on both the front and rear sides of the movable flat plate. Transverse chutes are provided on both adjusting bottom plates. One end of the transverse chute is an open end. The connecting plate is matched with the transverse chute, and the connecting plate is movably clamped in the transverse chute. The transverse chute is a bottle-shaped card slot structure with a smaller upper part and a larger lower part. Through the transverse chute, the movable clamping connection between the connecting plate and the adjusting bottom plate is realized. The connecting plate can drive the threaded rod to move left and right along the transverse chute, so as to adjust the left and right position of the motor shaft. And by designing one end of the transverse chute as an open end, it is convenient for subsequent installation operations, meeting the design requirements. And by designing the shape of the transverse chute as a bottle-shaped card slot structure with a smaller upper part and a larger lower part, the smaller upper size is matched with the threaded rod, and the larger lower size is matched with the connecting plate, which can improve the clamping stability of the threaded rod, the threaded rod and the adjusting bottom plate, and limit the up and down displacement of the connecting plate.

[0014] An installation method of an adjustment device for DC motor installation as described above is characterized in that it includes the following steps:

[0015] 1) Installation and fixation of the DC motor and the adjustment device:

[0016] (1) Press the side pressing plates on both sides so that the side pressing plates are attached to the sides of the side plates. Place the DC motor from the rear side of the fixed base plate so that the DC motor is placed on the rear end top surface of the fixed base plate, and the DC motor is located between the two side pressing plates. Release the side pressing plates. Pressing the side pressing plates first can ensure the maximum distance between the two side pressing plates, ensure that the DC motor can be placed between the two side pressing plates, and when installed from the rear side of the fixed base plate, it will not be blocked by the shaft support assembly and is also convenient for installation.

[0017] (2) Push the DC motor in the front side direction of the fixed base plate until the DC motor is completely located on the fixed base plate. At the same time, adjust the left and right positions of the DC motor on the fixed base plate so that the motor shaft is exactly placed on the lower support plate. Then, insert the adjusting bolt into the limit perforation of the upper pressing plate, align the adjusting bolt with the threaded hole on the lower support plate, and screw the end of the adjusting bolt into the threaded hole until the upper pressing plate touches the top of the motor shaft. Placing the body of the DC motor completely on the fixed base plate can ensure the stable supporting effect of the fixed base plate on the DC motor, improve the placement stability of the DC motor, and achieve precise positioning of the motor shaft through the lower support plate, ensuring that the DC motor is exactly located at the center position in the width direction of the fixed base plate, controlling and reducing the difference between the compression deformation amounts of the buffer compression springs in the side pressing assemblies on both sides, improving the structural balance stability of the combination of the DC motor and the fixed seat, and first clamping and limiting the motor shaft between the lower support plate and the upper pressing plate in combination with the upper pressing plate, which is convenient for subsequent adjustment and positioning of the motor shaft position.

[0018] (3) Loosen the second set screw, move the limit plate along the surface of the side plate. The limit plate drives the synchronous movement of the side pressing plate through the buffer assembly. When the side pressing plate moves to the middle position in the height direction of the side of the DC motor, tighten the second set screw. By adjusting the height of the limit plate, the height of the side pressing plate can be adjusted to ensure that the side pressing plate is located at the middle position in the height direction of the side of the DC motor, ensure the contact area between the side pressing plate and the DC motor, and improve the pressing and limiting effect of the side pressing plate on the side of the DC motor.

[0019] (4) Install the top pressing assembly. Insert the connecting rods at both ends of the positioning plate into the through grooves in the corresponding guide sleeves. Move the connecting rods until the positioning plate touches the top surface of the DC motor, and then tighten the third set screw. Then install the top pressing assembly. The top pressing assembly cooperates with the side pressing assembly to ensure the firm installation of the DC motor on the fixed base plate, improve the structural safety performance, and effectively prevent the DC motor from shaking, tilting, etc.

[0020] 2) Adjustment of the motor shaft position:

[0021] (1) Move the assembled DC motor and the adjustment device to the front end of the coupling shaft of the mechanical drive device to be connected, fix the adjustment base plate with the placement plane screw, loosen the first set screw, move the fixed base plate along the dovetail block until the end face of the motor shaft is moved to be flush with the end face of the coupling shaft on the mechanical drive device, and tighten the first set screw; move the fixed base plate along the dovetail block to adjust the front and rear position of the DC motor pressed and fixed on the fixed base plate, so that the end face of the motor shaft is flush with the end face of the coupling shaft on the mechanical drive device, which is convenient for use and adjustment;

[0022] (2) Rotate the limit nut along the threaded rod to adjust the height of the movable plate on the threaded rod. The movable plate drives the fixed seat and the DC motor to move synchronously, thereby adjusting the axis height of the motor shaft according to the axis height of the connecting shaft on the mechanical drive device, until the axis height of the motor shaft is moved to the same height as the axis height of the connecting shaft of the mechanical drive device; adjust the upper and lower heights of the movable plate, and finally adjust the upper and lower heights of the motor shaft of the DC motor, so that the axis height of the motor shaft of the DC motor is consistent with the axis height of the connecting shaft, thereby facilitating the subsequent docking and installation between the two shafts;

[0023] 3) Installation of motor bracket:

[0024] (1) According to the height of the top surface of the fixed base plate from the placement plane, two pressure plates of the same height are cut out, and the two pressure plates are respectively inserted into the two positioning holes on the fixed base plate, and the pressure plates are moved downward until the bottom surface of the pressure plates contacts the placement plane, and then the top end of the pressure plates is welded to the fixed base plate; after the end face and the axis height of the motor shaft are adjusted, the motor fixing frame is installed first. Since the axis height of the motor shaft is adjusted, the height of the top surface of the fixed base plate from the placement plane is the final installation height, so that pressure plates of the same height are cut out according to the final installation height. The pressure plates are initially clamped and limited with the fixed base plate through the positioning holes, which is convenient for installation. After ensuring that the pressure plates contact the placement plane, the pressure plates are fixed by welding to ensure the firmness of the connection between the pressure plates and the fixed base plate;

[0025] (2) Weld a horizontally placed mounting plate at the bottom of each of the two bearing plates, and then weld a reinforcing plate between the bearing plate and the mounting plate; then weld mounting plates on the opposite sides of the two bearing plates, and the bottom surface of the mounting plate is in contact with the placement plane, so as to facilitate the further fixation between the mounting plate and the placement plane, and the structural strength of the entire motor fixing bracket can be improved by welding the reinforcing plate, thereby ensuring the stable support of the motor fixing bracket for the DC motor. Moreover, placing the installation of the motor fixing bracket before adjusting the left and right positions of the motor shaft can avoid the movement of the connecting plate during the installation of the motor fixing bracket due to operations such as measurement and welding when adjusting left and right first and then installing the motor fixing bracket, which may affect the final adjustment position of the motor shaft;

[0026] (3) Move the connecting plate along the horizontal chute. The connecting plate drives the movable plate to move synchronously through the threaded rod. The movable plate drives the fixed seat and the DC motor to move synchronously until the axis of the motor shaft coincides with the axis of the coupling of the mechanical driving device. Then fix the mounting plate to the placement plane and connect the motor shaft to the coupling of the mechanical driving device; move the connecting plate to further adjust the left and right positions of the motor shaft, so that the axis of the motor shaft coincides with the axis of the coupling, which is convenient for the docking of the two. Moreover, after the motor shaft is adjusted, directly fix the DC motor on the placement plane through the mounting plate, thereby ensuring the limit fixation of the DC motor on the placement plane and ensuring that the axis of the motor shaft always coincides with the axis of the coupling;

[0027] 4) Removal of the adjusting seat:

[0028] (1) Remove the adjusting base plate from the placement plane, and then horizontally move the adjusting base plate so that the threaded rod and the connecting plate are completely removed from the open end of the horizontal chute;

[0029] (2) Remove the fixing block from the movable plate. Since the fixing block is connected to the threaded rod and the threaded rod is connected to the connecting plate, the fixing block, the threaded rod and the connecting plate are simultaneously removed from the movable plate. Then horizontally move the movable plate until the movable plate is completely removed from the dovetail chute; the overall disassembly and assembly are convenient. First, remove the adjusting base plate, and then remove the combination of the fixing block, the threaded rod and the connecting plate, so that the threaded rod, the fixing block and the connecting plate will not affect the removal of the movable plate. Finally, remove the movable plate, thereby completing the disassembly of the entire adjusting seat. The disassembled adjusting seat can be matched with other fixed seats for other adjustment operations of DC motor installation, and the design is ingenious and reasonable.

[0030] Due to the adoption of the above technical solutions, the present invention has the following beneficial effects:

[0031] The overall structure of the present invention is reasonably designed. Through the mutual cooperation of the fixed seat and the adjustment seat, the fixed seat stably supports the DC motor, and the fixed bottom plate ensures the stable placement of the DC motor. The side pressing component and the top pressing component press and limit the two sides and the top of the DC motor, ensuring the firm placement of the DC motor on the fixed seat, effectively preventing the shaking, tilting, etc. of the DC motor, improving the operation safety performance. The adjustment seat can adjust the position of the fixed seat in multiple directions, thereby adjusting the position of the DC motor on the fixed seat, and further precisely adjusting the position of the motor shaft on the DC motor, ensuring the precise positioning connection between the motor shaft and the mechanical drive device, improving the installation accuracy. Moreover, the fixed seat and the adjustment seat are designed as a detachable structure. After the motor shaft is installed and the motor fixing frame is installed and fixed, the fixed seat is retained to ensure the overall installation firmness of the DC motor, while the adjustment seat is disassembled and recycled.

[0032] First, the present invention preliminarily presses and limits the DC motor on the fixed seat through the side pressing component, moves the DC motor towards the shaft support component direction to ensure that the body of the DC motor is completely located on the fixed bottom plate, and at the same time adjusts the left and right positions of the DC motor so that the motor shaft is exactly placed on the shaft support component. The shaft support component precisely positions and clamps the motor shaft to ensure that the DC motor is exactly located on the left-right symmetry center line of the fixed bottom plate. Then, the top pressing component is installed, and the top pressing component presses and limits the top of the DC motor. Cooperating with the side pressing component, it ensures the stable placement of the DC motor on the fixed seat. Then, the position of the motor shaft is further adjusted in multiple directions of up and down, front and back to make the preliminary positioning of the coupling between the motor shaft and the mechanical drive device. Install the motor fixing frame, install and fix the DC motor through the motor fixing frame, and then further adjust the left and right positions of the motor shaft to make the precise positioning of the motor shaft and the coupling. The DC motor is fixed between the placement plane through the motor fixing frame, and the coupling between the motor shaft and the mechanical drive device is docked. Finally, the adjustment seat is disassembled. The entire installation process is clear, convenient, and simple. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0045] As Figures 1 to 9As shown in the figure, an adjustment device for DC motor installation according to the present invention includes a fixed base 1 and an adjustment base 2. The fixed base 1 is located on the adjustment base 2, and the fixed base 1 is detachably connected to the adjustment base 2. The fixed base 1 includes a fixed bottom plate 3, a side pressure component 4 and a top pressure component 5. The side pressure component 4 is connected to the fixed bottom plate 3, and the top pressure component 5 is connected to the side pressure component 4. Two symmetrically arranged positioning jacks 6 are provided on the fixed bottom plate 3. The positioning jacks 6 can facilitate the positioning and installation between the motor fixing bracket and the fixed bottom plate 3 during the installation of the DC motor 45. At the same time, the symmetrical arrangement can ensure that the two motor fixing brackets are symmetrically arranged on both sides of the fixed bottom plate 3, ensuring the overall balance and stability of the DC motor 45 installation. The adjustment base 2 includes an adjustment bottom plate 7 and a movable flat plate 8. The movable flat plate 8 is adjustably connected to the adjustment bottom plate 7. The movable flat plate 8 is located above the adjustment bottom plate 7. The fixed bottom plate 3 is located on the top surface of the movable flat plate 8, and the fixed bottom plate 3 is adjustably connected to the movable flat plate 8.

[0046] There are two side pressure components 4, and the two side pressure components 4 are symmetrically arranged on the top surface of the fixed bottom plate 3. Each of the two side pressure components 4 includes a side plate 21, a buffer component 22 and a side pressure plate 23. The side plate 21 is fixedly connected to the fixed bottom plate 3. The buffer components 22 are evenly arranged on the side plate 21. The buffer components 22 are limited and fixed to the side plate 21 through limit members. The side pressure plate 23 is connected to the buffer component 22. The side pressure plate 23 is located inside the side plate 21. Through the two symmetrically arranged side pressure components 4, the left and right sides of the DC motor 45 are simultaneously pressed and limited, ensuring the stability of the DC motor 45 placed on the fixed base 1. The buffer component 22 is connected to the side pressure plate 23. Due to the compressible design of the buffer component 22, the side pressure plate 23 can be adjusted according to the actual width of the DC motor 45, ensuring that the side pressure plate 23 abuts and presses against the side of the DC motor 45, and ensuring the pressing effect of the side pressure plate 23 on the DC motor 45.

[0047] Heat dissipation slot holes 24 are evenly arranged on the side plate 21. The buffer component 22 includes a limit sleeve 25, a buffer compression spring 26 and a support plate 27. The limit sleeve 25 is matched with the heat dissipation slot hole 24, and the limit sleeve 25 is movably clamped in the heat dissipation slot hole 24. One end of the buffer compression spring 26 is located in the installation slot of the limit sleeve 25, and the support plate 27 is located at the other end of the buffer compression spring 26. The support plate 27 is fixedly connected to the side pressure plate 23 by screws. Through the design of the heat dissipation slot holes 24, the ventilation and heat dissipation effects on both sides of the DC motor 45 can be ensured. At the same time, the heat dissipation slot holes 24 can facilitate the installation and limitation of the buffer component 22. The limit sleeve 25 is matched with the heat dissipation slot hole 24 to realize the preliminary clamping and limitation of the buffer component 22 and the side plate 21. The part of the buffer compression spring 26 exposed outside the limit sleeve 25 and the support plate 27 pass through the heat dissipation slot hole 24 and extend to the inside of the side plate 21, and then the support plate 27 is fixedly connected to the side pressure plate 23 by screws. The overall disassembly and assembly are convenient and simple, and the design is reasonable.

[0048] The limiting member includes a limiting plate 28 and a second set screw 29. A folding plate 30 is provided at the end of the limiting sleeve 25. The folding plate 30 is fixedly screwed to the limiting plate 28. Limiting slots 31 are provided at both the front and rear ends of the side plate 21. Both the front and rear ends of the limiting plate 28 are tightly abutted and limited against the side plate 21 by the second set screw 29. The second set screw 29 passes through the limiting plate 28 and extends into the limiting slot 31. The limiting sleeve 25 is fixedly screwed to the limiting plate 28 through the folding plate 30 at its end, ensuring the firm installation performance between the buffer assembly 22 and the limiting plate 28. At the same time, the folding plate 30 can play a limiting role. The width of the folding plate 30 is greater than the width of the heat dissipation slot hole 24. When the limiting sleeve 25 is inserted into the heat dissipation slot hole 24 and the folding plate 30 abuts against the outer side surface of the side plate 21, the limiting sleeve 25 is inserted in place, facilitating the actual installation and positioning. The limiting plate 28 itself is tightly abutted and limited against the side plate 21 through the second set screw 29. Loosening the second set screw 29 can adjust the vertical height of the limiting plate 28, thereby adjusting the installation height of the buffer assembly 22, and further adjusting the vertical height of the side pressing plate 23, so that the side pressing plate 23 can be appropriately adjusted according to the actual height of the DC motor 45, ensuring the pressing and limiting effect of the side pressing plate 23 on the side of the DC motor 45. The design of the limiting slot 31 can increase the contact area between the second set screw 29 and the side plate 21, thereby improving the tightening effect of the second set screw 29.

[0049] The top pressing assembly 5 includes a positioning plate 32 and a connecting rod 33. The connecting rods 33 are symmetrically arranged on the left and right sides of the positioning plate 32. Guide sleeves 34 are provided on the top surfaces of the left and right side plates 21. The vertical section of the connecting rod 33 matches the through slot 35 on the guide sleeve 34. The vertical section of the connecting rod 33 is inserted into the through slot 35, and the connecting rod 33 is tightly abutted and limited against the guide sleeve 34 by a third set screw 36. The connecting rod 33 cooperates with the through slot 35 to achieve the movable clamping connection between the positioning plate 32 and the guide sleeve 34, and then the positioning plate 32 and the guide sleeve 34 are tightly abutted and limited through the third set screw 36, ensuring the connection stability between the two, thereby ensuring the pressing and limiting effect of the positioning plate 32 on the top surface of the DC motor 45. Moreover, loosening the third set screw 36 can adjust the vertical height of the positioning plate 32, so that the positioning plate 32 can be adjusted according to the actual height of the DC motor 45, ensuring the pressing and limiting effect of the positioning plate 32 on the DC motor 45.

[0050] On the front side of the fixed base plate 3, a shaft support assembly 37 is provided. The shaft support assembly 37 includes a lower support plate 38 and an upper pressing plate 39. The lower support plate 38 is fixedly connected to the fixed base plate 3. The upper pressing plate 39 is connected to the lower support plate 38 through an adjusting bolt 40. A limiting through hole 41 is provided on the upper pressing plate 39, and a threaded hole 42 is provided on the lower support plate 38. Both the limiting through hole 41 and the threaded hole 42 are matched with the adjusting bolt 40. The adjusting bolt 40 passes through the limiting through hole 41 and is threadedly connected in the threaded hole 42. The motor shaft of the DC motor 45 is assisted in supporting and clamping through the shaft support assembly 37, improving the installation firmness between the DC motor 45 and the fixed seat 1. The motor shaft is clamped and limited between the lower support plate 38 and the upper pressing plate 39, and the connection between the lower support plate 38 and the upper pressing plate 39 is realized through the ingenious design of the adjusting bolt 40. By adjusting the length of the bottom end of the adjusting bolt 40 screwed into the threaded hole 42, the distance between the lower support plate 38 and the upper pressing plate 39 can be adjusted, so as to realize the clamping and support of motor shafts with different shaft diameters.

[0051] On the bottom surface of the fixed base plate 3, a convex block 9 is provided. On the convex block 9, a dovetail-shaped chute 10 is provided. On the top surface of the movable flat plate 8, a dovetail-shaped block 11 is provided. The dovetail-shaped block 11 is matched with the dovetail-shaped chute 10. The convex block 9 is movably clamped on the dovetail-shaped block 11 through the dovetail-shaped chute 10. The convex block 9 slides back and forth along the dovetail-shaped block 11, and the convex block 9 is tightly abutted and limited with the dovetail-shaped block 11 through a first set screw 12. Through the cooperation of the dovetail-shaped chute 10 and the dovetail-shaped block 11, the movable clamping connection between the fixed base plate 3 and the movable flat plate 8 is realized. Further, through the tight abutment and limitation of the first set screw 12, the clamping firmness between the fixed base plate 3 and the movable flat plate 8 is ensured. Moreover, through the clamping connection method, it is also more convenient to further adjust the position of the motor shaft subsequently. The ingenious design of the dovetail shape can limit the up and down movement of the fixed base plate 3, improving the clamping smoothness between the fixed base plate 3 and the movable flat plate 8, so that the fixed base plate 3 can only slide back and forth along the dovetail-shaped block 11, thus realizing the adjustment of the front and back positions of the motor shaft. When the position needs to be adjusted, loosen the first set screw 12, and the operation is convenient and simple.

[0052] Fixing blocks 13 are provided at the four corners of the movable flat plate 8. The fixing blocks 13 are fixed to the movable flat plate 8 by screws. A perforation 14 is provided on the fixing block 13. A threaded rod 15 is provided in the perforation 14. The threaded rod 15 is limited and fixed to the fixing block 13 by a limit nut 16. The limit nut 16 is located on the upper and lower sides of the fixing block 13. Two adjacent threaded rods 15 on the left and right are connected by a connecting plate 17. Connecting screw holes 18 are provided at both ends of the connecting plate 17. The connecting screw holes 18 match the threaded rods 15. The bottom end of the threaded rod 15 is threadedly connected in the connecting screw hole 18. The overall structural design is ingenious and reasonable. The fixing block 13 is movably sleeved on the threaded rod 15 through the perforation 14 to realize the indirect connection between the movable flat plate 8 and the threaded rod 15. Each fixing block 13 is limited and fixed on the threaded rod 15 by the clamping and limiting of the upper and lower two limit nuts 16 to ensure the installation stability between the movable flat plate 8 and the threaded rod 15. And by adjusting the position of the limit nut 16 on the threaded rod 15, the position of the fixing block 13 can be adjusted, so as to adjust the up and down height of the movable flat plate 8. The two threaded rods 15 on the left and right are connected by a connecting plate 17. The connecting plate 17 can cooperate with the adjusting bottom plate 7 to realize the further clamping connection between the threaded rod 15 and the adjusting bottom plate 7, which is convenient for actual installation and positioning. Moreover, through the ingenious design of the connecting screw hole 18, the threaded connection between the threaded rod 15 and the connecting plate 17 is realized, which ensures the connection firmness between the threaded rod 15 and the connecting plate 17, and this connection method is detachable, which is convenient for actual assembly.

[0053] Adjusting bottom plates 7 are provided on the front and back sides of the movable flat plate 8. Transverse chutes 19 are provided on both of the two adjusting bottom plates 7. One end of the transverse chute 19 is an open end. The connecting plate 17 matches the transverse chute 19. The connecting plate 17 is movably clamped in the transverse chute 19. The transverse chute 19 is a bottle-shaped card slot structure with a smaller upper part and a larger lower part. Through the transverse chute 19, the movable clamping connection between the connecting plate 17 and the adjusting bottom plate 7 is realized. The connecting plate 17 can drive the threaded rod 15 to move left and right along the transverse chute 19, so as to adjust the left and right position of the motor shaft. And by designing one end of the transverse chute 19 as an open end, it is convenient for subsequent installation operations, which meets the design requirements. And by designing the shape of the transverse chute 19 as a bottle-shaped card slot structure with a smaller upper part and a larger lower part, the smaller size of the upper part matches the threaded rod 15, and the larger size of the lower part matches the connecting plate 17, which can improve the clamping stability of the threaded rod 15 and the adjusting bottom plate 7 and limit the up and down displacement of the connecting plate 17.

[0054] As Figure 10 shown, an installation method of an adjustment device for DC motor installation as described above includes the following steps:

[0055] 1) Installation and fixation of the DC motor 45 and the adjustment device:

[0056] (1) Press the side pressing plates 23 on both sides so that the side pressing plates 23 are attached to the sides of the side plates 21. Place the DC motor 45 from the rear side of the fixed base plate 3 so that the DC motor 45 is placed on the rear end top surface of the fixed base plate 3, and the DC motor 45 is located between the two side pressing plates 23. Then release the side pressing plates 23. First pressing the side pressing plates 23 can ensure the maximum distance between the two side pressing plates 23, ensure that the DC motor 45 can be placed between the two side pressing plates 23, and when installed from the rear side of the fixed base plate 3, it will not be blocked by the shaft support assembly 37 and is also convenient for installation;

[0057] (2) Push the DC motor 45 in the forward direction of the fixed base plate 3 until the DC motor 45 is completely located on the fixed base plate 3. At the same time, adjust the left and right positions of the DC motor 45 on the fixed base plate 3 so that the motor shaft is exactly placed on the lower support plate 38. Then insert the adjusting bolt 40 into the limit perforation 41 of the upper pressing plate 39, align the adjusting bolt 40 with the threaded hole 42 on the lower support plate 38, and screw the end of the adjusting bolt 40 into the threaded hole 42 until the upper pressing plate 39 abuts against the top of the motor shaft. Placing the body of the DC motor 45 completely on the fixed base plate 3 can ensure the stable supporting effect of the fixed base plate 3 on the DC motor 45, improve the placement stability of the DC motor 45, and achieve the precise positioning of the motor shaft through the lower support plate 38 to ensure that the DC motor 45 is exactly located at the center position in the width direction of the fixed base plate 3. Control and reduce the difference between the compression deformation amounts of the buffer compression springs 26 in the side pressing assemblies 4 on both sides to improve the structural balance stability of the combination of the DC motor 45 and the fixed seat 1. And first clamp and limit the motor shaft between the lower support plate 38 and the upper pressing plate 39 in combination with the upper pressing plate 39, which is convenient for subsequent adjustment and positioning of the motor shaft position;

[0058] (3) Loosen the second set screw 29 and move the limit plate 28 along the surface of the side plate 21. The limit plate 28 drives the synchronous movement of the side pressing plate 23 through the buffer assembly 22. When the side pressing plate 23 moves to the middle position in the height direction of the side of the DC motor 45, tighten the second set screw 29. By adjusting the height of the limit plate 28, the height of the side pressing plate 23 is adjusted to ensure that the side pressing plate 23 is located at the middle position in the height direction of the side of the DC motor 45, ensure the contact area between the side pressing plate 23 and the DC motor 45, and improve the pressing and limiting effect of the side pressing plate 23 on the side of the DC motor 45;

[0059] (4) Install the top pressing component 5. Insert the connecting rods 33 at both ends of the positioning plate 32 into the through grooves 35 in the corresponding guide sleeves 34. Move the connecting rods 33 until the positioning plate 32 touches the top surface of the DC motor 45, and then tighten the third set screw 36. Then install the top pressing component 5. The top pressing component 5 cooperates with the side pressing component 4 to ensure the firm installation of the DC motor 45 on the fixed base plate 3, improve the structural safety performance, and effectively prevent the DC motor 45 from shaking, tilting, etc.;

[0060] 2) Adjustment of the motor shaft position:

[0061] (1) Move the whole assembled DC motor 45 and the adjusting device to the front end of the coupling of the mechanical driving device to be connected. Fix the adjusting base plate 7 to the placement plane with screws. Loosen the first set screw 12 and move the fixed base plate 3 along the dovetail-shaped block 11 until the end face of the motor shaft is flush with the end face of the coupling on the mechanical driving device, and then tighten the first set screw 12. Move the fixed base plate 3 along the dovetail-shaped block 11 to adjust the front and rear positions of the DC motor 45 firmly fixed on the fixed base plate 3, so that the end face of the motor shaft is flush with the end face of the coupling on the mechanical driving device, which is convenient to use;

[0062] (2) Rotate the limit nut 16 along the threaded rod 15 to adjust the height of the movable flat plate 8 on the threaded rod 15. The movable flat plate 8 drives the synchronous movement of the fixed seat 1 and the DC motor 45, so as to adjust the axial center height of the motor shaft according to the axial center height of the coupling on the mechanical driving device until the axial center of the motor shaft is moved to be consistent with the axial center height of the coupling on the mechanical driving device. Adjust the up and down height of the movable flat plate 8 to finally realize the adjustment of the up and down height of the motor shaft of the DC motor 45, so that the axial center of the motor shaft of the DC motor 45 is consistent with the axial center height of the coupling, which is convenient for the subsequent docking installation between the two shafts;

[0063] 3) Installation of the motor fixing bracket:

[0064] (1) Cut out two bearing plates 42 with the same height according to the height from the top surface of the fixed base plate 3 to the placement plane. Insert the two bearing plates 42 into the two positioning jacks 6 on the fixed base plate 3 respectively. Move the bearing plates 42 downward until the bottom surface of the bearing plates 42 touches the placement plane, and then weld the top ends of the bearing plates 42 to the fixed base plate 3. After the end face and axial center height of the motor shaft are adjusted, install the motor fixing bracket first. Since the axial center height of the motor shaft is adjusted, the height from the top surface of the fixed base plate 3 to the placement plane is the final installation height. Thus, cut out the bearing plates 42 with the same height according to the final installation height. The bearing plates 42 are initially clamped and limited with the fixed base plate 3 through the positioning jacks 6, which is convenient for installation. After ensuring that the bearing plates 42 touch the placement plane, then ensure the firm connection between the bearing plates 42 and the fixed base plate 3 through welding;

[0065] (2) Weld a horizontally placed mounting plate 43 to the bottom end of each of the two bearing plates 42, and then weld a reinforcing plate 44 between the bearing plate 42 and the mounting plate 43; then weld the mounting plate 43 to the opposite surfaces of the two bearing plates 42, and the bottom surface of the mounting plate 43 contacts the placement plane, so as to facilitate further fixation between the mounting plate 43 and the placement plane, and the structural strength of the entire motor fixing bracket can be improved by welding the reinforcing plate 44, making the motor fixing bracket not easily deformed, thus ensuring the stable supporting effect of the motor fixing bracket on the DC motor 45. Moreover, placing the installation of the motor fixing bracket before adjusting the left and right positions of the motor shaft can avoid the movement of the connecting plate 17 during the installation of the motor fixing bracket due to operations such as measurement and welding when adjusting left and right first and then installing the motor fixing bracket, and the connecting plate 17 is only movably clamped in the transverse chute 19, which may affect the final adjusted position of the motor shaft;

[0066] (3) Move the connecting plate 17 along the transverse chute 19. The connecting plate 17 drives the movable flat plate 8 to move synchronously through the threaded rod 15, and the movable flat plate 8 drives the fixed seat 1 and the DC motor 45 to move synchronously until the axis of the motor shaft moves to coincide with the axis of the coupling of the mechanical drive device. Then fix the mounting plate 43 to the placement plane, and connect the motor shaft to the coupling of the mechanical drive device; move the connecting plate 17 to further adjust the left and right positions of the motor shaft, so that the axis of the motor shaft coincides with the axis of the coupling, facilitating the docking of the two. Moreover, after the motor shaft is adjusted, directly fix the DC motor 45 to the placement plane through the mounting plate 43. The mounting plate 43 and the placement plane can be fixed by various methods such as welding and screws, thus ensuring the limit fixation of the DC motor 45 on the placement plane and ensuring that the axis of the motor shaft always coincides with the axis of the coupling;

[0067] 4) Removal of the adjusting seat 2:

[0068] (1) Remove the adjusting base plate 7 from the placement plane, and then horizontally move the adjusting base plate 7 so that the threaded rod 15 and the connecting plate 17 are completely removed from the open end of the transverse chute 19;

[0069] (2) Remove the fixed block 13 from the movable flat plate 8. Since the fixed block 13 is connected to the threaded rod 15, and the threaded rod 15 is connected to the connecting plate 17, the fixed block 13, the threaded rod 15 and the connecting plate 17 are removed from the movable flat plate 8 at the same time. Then move the movable flat plate 8 horizontally until the movable flat plate 8 is completely removed from the dovetail chute 10. The overall disassembly and assembly are convenient. First, remove the adjusting base plate 7, and then remove the combination of the fixed block 13, the threaded rod 15 and the connecting plate 17, so that the threaded rod 15, the fixed block 13 and the connecting plate 17 will not affect the removal of the movable flat plate 8. Finally, remove the movable flat plate 8 to complete the disassembly of the entire adjusting seat 2. The disassembled adjusting seat 2 can be matched with other fixed seats 1, and then the adjustment operation of the installation of other DC motors 45 can be carried out. The design is ingenious and reasonable.

[0070] The overall structure of the present invention is reasonably designed. Through the mutual cooperation of the fixed seat 1 and the adjusting seat 2, the fixed seat 1 stably supports the DC motor 45, and the fixed bottom plate 3 ensures the stable placement of the DC motor 45. The side pressing assembly 4 and the top pressing assembly 5 press and limit the two sides and the top of the DC motor 45 to ensure the firm placement of the DC motor 45 on the fixed seat 1, effectively preventing the shaking and tilting of the DC motor 45, etc., and improving the operation safety performance. The adjusting seat 2 can adjust the position of the fixed seat 1 in multiple directions, so as to adjust the position of the DC motor 45 on the fixed seat 1, and further accurately adjust the position of the motor shaft on the DC motor 45 to ensure the accurate positioning connection between the motor shaft and the mechanical drive device, improve the installation accuracy, and design the fixed seat 1 and the adjusting seat 2 into a detachable structure. After the motor shaft is installed and the motor fixing frame is installed and fixed, the fixed seat 1 is retained to ensure the overall installation firmness of the DC motor 45, while the adjusting seat 2 is disassembled and assembled for recycling.

[0071] In the present invention, first, the DC motor 45 is preliminarily pressed and limited on the fixed seat 1 by the side pressing component 4. The DC motor 45 is moved towards the shaft support component 37 to ensure that the body of the DC motor 45 is completely located on the fixed bottom plate 3. At the same time, the left and right positions of the DC motor 45 are adjusted so that the motor shaft is exactly placed on the shaft support component 37. The shaft support component 37 precisely positions and clamps the motor shaft to ensure that the DC motor 45 is exactly located on the left-right symmetry center line of the fixed bottom plate 3. Then, the top pressing component 5 is installed. The top of the DC motor 45 is pressed and limited by the top pressing component 5. Cooperating with the side pressing component 4, the placement stability of the DC motor 45 on the fixed seat 1 is ensured. Further adjustments are made to the position of the motor shaft in multiple directions, including up and down, front and back, so that the connection shaft of the motor shaft and the mechanical drive device is preliminarily positioned. The motor fixing bracket is installed, and the DC motor 45 is installed and fixed by the motor fixing bracket. Then, the left and right positions of the motor shaft are further adjusted so that the motor shaft is precisely positioned with the connection shaft. The DC motor 45 is fixed between the placement plane through the motor fixing bracket, and the connection shaft of the motor shaft and the mechanical drive device is docked. Finally, the adjusting seat 2 is disassembled. The entire installation process is clear, convenient, and simple.

[0072] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications made based on the present invention to achieve substantially the same technical effects are all covered by the protection scope of the present invention.
