Description

Technical Field

[0001] This utility model relates to the field of servo motor slide table processing technology, specifically, to an assembly fixture for servo motor slide tables. Background Technology

[0002] As a key execution component in automated equipment, the servo motor slide table mainly consists of a servo motor, a transmission mechanism (such as a ball screw), and the slide table body (including slider, guide rail, worktable, etc.). The servo motor serves as the power source, converting rotary motion into linear motion of the slide table through the transmission mechanism. The slider and guide rail work closely together to ensure smooth movement of the slide table, while the worktable is used to mount various workpieces or components.

[0003] In actual production, in order to ensure the assembly accuracy and efficiency of servo motor slides, assembly tooling is often used to splice and assemble them. The usual assembly process is to first assemble the slide rails, sliders, ball screws, worktables and other components to form a relatively complete slide structure, thereby providing a stable benchmark and support for motor installation. It also facilitates the preliminary debugging and inspection of the slide mechanical parts, and the motor is installed only after ensuring that the mechanical structure is normal.

[0004] However, a prominent problem exists during motor installation: dustproof installation is usually inconvenient. Once dust enters the connection between the motor and the slide, such as the coupling, the connection area between the motor shaft and the ball screw, it may cause many adverse effects. Dust will accelerate component wear, reduce transmission accuracy, affect the matching performance between the motor and the slide, and cause phenomena such as jamming and shaking when the slide is running. It may also enter the motor, interfere with encoder signal transmission, affect motor control accuracy, and in severe cases, affect the normal operation and production efficiency of the entire automation equipment.

[0005] Therefore, there is an urgent need for an assembly fixture for servo motor slides to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned shortcomings and provide an assembly fixture for a servo motor slide table that uses an adjustable side plate and a bending plate to form a limiting cavity, cooperates with a sweeping bar structure to achieve pre-cleaning, and uses a sliding limiting rod and a limiting groove to ensure sliding accuracy.

[0007] The side plate is connected to the bending plate with bolts, allowing the size of the limiting cavity to be flexibly adjusted according to the size of the slide body. A sweeping strip is installed on the side plate to clean impurities on the surface of the slide body in advance when the slide slides, so as to realize the docking and installation of the servo motor and the pre-cleaned slide body. At the same time, the side plate can center the slide body during docking, and with the precise sliding of the sliding limit rod in the limit groove, the docking accuracy is guaranteed twice, which effectively improves the assembly efficiency and quality of the servo motor slide and reduces component wear caused by dust.

[0008] This utility model provides an assembly fixture for a servo motor slide, which includes an assembly workbench, a support base rod fixedly installed at the bottom of the assembly workbench for supporting it, an extension plate fixedly installed at the bottom of the assembly workbench, and a slide fixing mechanism installed on the top of one side of the assembly workbench for fixing and supporting the servo motor slide body.

[0009] The assembly workbench is equipped with an assembly mechanism, which includes a drive component and an assembly component. The drive component is connected to the assembly component and can drive the assembly component to slide on the surface of the assembly workbench. The assembly component includes a slide plate, and a bending plate is fixedly installed on the surface of the slide plate. The servo motor to be installed can be locked and limited on the surface of the slide plate, and dust prevention is achieved in conjunction with the bending plate. During the sliding of the slide plate, the servo motor and the servo motor slide body are docked and assembled.

[0010] As a further improvement to this technical solution, the slide table fixing mechanism includes a lifting support frame fixedly installed on one side surface of the assembly workbench. The two ends of the lifting support frame have a raised structure. A movable support plate is slidably provided inside the side of the lifting support frame near the end of the assembly workbench. The movable support plate is connected to the lifting support frame by a gasket, which is made of elastic material.

[0011] As a further improvement to this technical solution, the drive assembly includes a drive cavity located in the middle of the assembly workbench. A conveyor is installed inside the drive cavity. The conveyor includes two gears, and a synchronous belt meshes between the two gears. The surface of the synchronous belt is flush with the surface of the assembly workbench. An outer cavity is opened inside the extension plate, and a motor is fixedly installed inside the outer cavity. The shaft of one of the gears is fixedly connected to the output shaft of the motor.

[0012] As a further improvement to this technical solution, the assembly also includes side plates bolted to the bottom of both sides of the bending plate, forming a limiting cavity between the two side plates and the bending plate, the bottom of the slide plate being fixedly mounted on the surface of the timing belt, and the top of the slide plate being provided with a servo motor positioning groove.

[0013] As a further improvement to this technical solution, multiple scanning strips are fixedly installed on the side surface of both side plates near the limiting cavity.

[0014] As a further improvement to this technical solution, the surface of the assembly workbench is provided with two limiting grooves, and a sliding limiting rod is slidably provided inside each of the two limiting grooves. The two sliding limiting rods are respectively fixedly installed on the bottom of the two sides of the slide plate on the side away from the limiting groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this assembly fixture for servo motor slides, the servo motor slide body can be fixed on the surface of the assembly workbench through the pads and movable support plates. The gears of the drive component cooperate with the synchronous belt to precisely drive the assembly component to slide. The slide plate and bending plate of the assembly component, together with the side plate, form a limiting cavity and a dustproof structure. The positioning groove on the slide plate facilitates the installation of the servo motor, and the sliding limit rod ensures the stability of the assembly component's movement.

[0017] It is worth mentioning that the sweeping bar on the side plate contacts the servo motor slide body before it during the sliding docking process, which can pre-clean it. Combined with the limiting cavity, the servo motor can dock and install with the pre-cleaned slide body. Moreover, the installation positions of the two side plates are adjustable, the limiting cavity can adapt to the surface of the slide body, and the side plates can also center the slide body during docking, further improving the docking accuracy. Ultimately, this achieves efficient docking and assembly of the servo motor and the servo motor slide body, effectively improving assembly efficiency and quality. Attached Figure Description

[0033] In the assembly of servo motor slides, although tooling is used for splicing, and the slide components are assembled first before the motor to ensure accuracy and facilitate debugging, dust prevention is often inconvenient during motor installation. Once dust enters the connection between the motor and the slide, it will accelerate component wear, reduce transmission and control accuracy, affect mating performance, and even cause short circuits, affecting equipment operation. Therefore, an assembly tooling for servo motor slides is proposed, see reference. Figures 1-3 As shown, the device includes an assembly workbench 1, a support base rod 11 for supporting the bottom of the assembly workbench 1, an extension plate 12 for supporting the bottom of the assembly workbench 1, and a slide table fixing mechanism 2 for fixing and supporting the servo motor slide table body 10.

[0034] The assembly workbench 1 is equipped with an assembly mechanism 3. The assembly mechanism 3 includes a drive component 31 and an assembly component 32. The drive component 31 is connected to the assembly component 32 and can drive the assembly component 32 to slide on the surface of the assembly workbench 1. The assembly component 32 includes a slide plate 321. A bending plate 322 is fixedly installed on the surface of the slide plate 321. The servo motor to be installed can be locked and limited on the surface of the slide plate 321, and dustproofing is achieved in conjunction with the bending plate 322. During the sliding of the slide plate 321, the servo motor and the servo motor slide body 10 are docked and assembled.

[0035] First, the servo motor slide body 10 is positioned by the slide fixing mechanism 2. The specific structure of the slide fixing mechanism 2 is disclosed below. The slide fixing mechanism 2 includes a lifting support frame 21 fixedly installed on one side surface of the assembly workbench 1. The two ends of the lifting support frame 21 are protruding structures. A movable support plate 22 is slidably provided inside the side of the lifting support frame 21 near the end of the assembly workbench 1. The movable support plate 22 and the lifting support frame 21 are connected by a gasket 23, which is made of elastic material.

[0036] See Figure 4 As can be seen, the slide table fixing mechanism 2 consists of a lifting support frame 21, a movable support plate 22, and an elastic pad 23. The lifting support frame 21 is fixed to one side of the assembly workbench 1, and its two protruding structures can horizontally limit the servo motor slide table body 10. The movable support plate 22 can slide inside the lifting support frame 21 and can flexibly adjust its position according to the actual size of the slide table body. The elastic pad 23 connects the two, which can not only buffer vibration and impact, but also provide appropriate resistance for the movable support plate 22 to maintain stability. The three work together to achieve reliable fixed support for servo motor slide table bodies 10 of different specifications, laying a stable foundation for the subsequent precise docking of the servo motor and the servo motor slide table body 10.

[0037] Next, the specific structure of the drive assembly 31 is disclosed. The drive assembly 31 includes a drive cavity 312 opened in the middle of the assembly workbench 1. A conveyor 311 is installed inside the drive cavity 312. The conveyor 311 includes two gears 3102. A synchronous belt 3101 meshes between the two gears 3102. The surface of the synchronous belt 3101 is flush with the surface of the assembly workbench 1. An outer cavity 313 is opened inside the extension plate 12. A motor is fixedly installed inside the outer cavity 313. The shaft of one of the gears 3102 is fixedly connected to the output shaft of the motor.

[0038] Combination Figure 3 and Figure 4 As shown, the drive assembly 31 is a key part of the servo motor slide assembly fixture for achieving automated assembly. Its core structure is based on the assembly workbench 1. A drive cavity 312 is set in the middle of the assembly workbench 1. This cavity provides installation space for the internal conveyor 311. The conveyor 311 consists of two gears 3102 and a synchronous belt 3101. The two gears 3102 mesh with each other, and the synchronous belt 3101 surrounds the outside of the gears 3102 to form a transmission system. In particular, in the middle of the synchronous belt 3101, that is, in the position between the two gears 3102, multiple support tubes are meshed. The function of these support tubes is to provide support force for the synchronous belt 3101, reduce the sagging and deformation of the synchronous belt 3101 due to bearing the weight of the assembly assembly 32 during operation, and ensure that the synchronous belt 3101 can run stably.

[0039] The design of the synchronous belt 3101 being flush with the surface of the assembly workbench 1 ensures the smoothness of the assembly component 32 when sliding on the workbench surface and reduces jamming caused by height difference. The outer cavity 313 inside the extension plate 12 is used to install the drive motor. The motor output shaft is connected to the shaft of one of the gears 3102. When the motor starts running, it drives the gear 3102 connected to it to rotate. Through the meshing transmission between the gear 3102 and the synchronous belt 3101, the synchronous belt 3101 is made to circulate, thereby driving the assembly component 32 fixed on the synchronous belt 3101 to slide on the surface of the assembly workbench 1.

[0040] Finally, the specific structure of the drive assembly 31 is disclosed. The assembly assembly 32 also includes side plates 323 bolted to the bottom of both sides of the bending plate 322. A limiting cavity 324 is formed between the two side plates 323 and the bending plate 322. The bottom of the slide plate 321 is fixedly installed on the surface of the timing belt 3101. A servo motor positioning groove 325 is provided on the top of the slide plate 321.

[0041] Multiple sweeping strips 5 are fixedly installed on the side surface of both side plates 323 near the limiting cavity 324.

[0042] The improvements are: See Figure 2 and Figure 3 As shown, the bottom of the slide plate 321 is fixed to the surface of the timing belt 3101, forming a linkage with the drive assembly 31. When the motor in the drive assembly 31 drives the gear 3102 to rotate, the slide plate 321 can achieve smooth and precise sliding on the surface of the assembly workbench 1 through the transmission of the timing belt 3101. Figure 6 It can be seen that the servo motor positioning slot 325 set on the top of the skateboard 321 is precisely designed according to the outline of the servo motor. It can initially fix the servo motor in the designated position through mechanical limiting, ensuring that the motor will not shift during subsequent docking, laying the foundation for precise assembly.

[0043] Combination Figure 5 and Figure 6As shown, the bent plate 322 and the side plates 323 on both sides are connected by bolts to form a limiting cavity 324. This bolt connection method has extremely high flexibility. Users can fine-tune the installation position of the side plates 323 according to the specific size specifications of the servo motor slide body 10, so that the limiting cavity 324 can fit tightly against different models of servo motor slide body 10. During the docking process, the two side plates 323 can center and position the servo motor slide body 10, effectively correcting any possible installation deviations and further improving the accuracy of docking. At the same time, their proximity to the limiting cavity 324... Multiple sweeping strips 5 fixed on the side surface will first contact the servo motor slide body 10 when the slide plate 321 slides. Through physical cleaning, they remove dust, debris and other impurities from the surface of the slide body. Together with the bending plate 322, they form a relatively closed dustproof space, which greatly reduces the risk of dust entering the connection between the servo motor and the servo motor slide body 10. This effectively reduces problems such as component wear and transmission accuracy reduction caused by dust accumulation, ensuring that the assembled servo motor slide has good operating performance and a long service life, and achieving efficient, accurate and reliable automated assembly.

[0044] During the assembly process of the servo motor and the servo motor slide body 10, it is necessary to ensure that the sliding plate 321 has a precise trajectory and stable operation, and to reduce the impact of deviation, shaking, and other issues on the assembly accuracy and quality. Therefore, through... Figure 2 and Figure 5 As shown, the surface of the assembly workbench 1 has two limiting grooves 4, and a sliding limiting rod 41 is slidably provided inside each of the two limiting grooves 4. The two sliding limiting rods 41 are fixedly installed on the bottom sides of the slide plate 321 on the side away from the limiting grooves 4.

[0045] The improvement lies in the following: When the drive assembly 31 drives the synchronous belt 3101 to rotate, causing the slide plate 321 fixed on the synchronous belt 3101 to begin sliding, the sliding limit rod 41 slides within the limit groove 4. The limit groove 4 provides a clear sliding trajectory for the sliding limit rod 41, restricting it to move only along the specified path within the groove. This ensures that the slide plate 321 slides smoothly along a preset straight line, effectively preventing the slide plate 321 from shifting left or right or wobbling during the sliding process. This allows the servo motor fixed on the slide plate 321 to accurately dock and assemble with the servo motor slide body 10, greatly improving the assembly accuracy and quality. Simultaneously, the cooperation between the sliding limit rod 41 and the limit groove 4 enhances the stability of the entire assembly process, reducing assembly errors caused by vibration or external interference, and ensuring that the assembly of the servo motor slide can be completed efficiently and reliably.

[0046] In summary, the working principle of this solution is as follows: First, the servo motor slide body 10 is horizontally limited by the protruding structures at both ends of the lifting support frame 21 of the slide fixing mechanism 2. The slide body is flexibly adjusted and stably fixed according to its actual dimensions using the sliding support plate 22 and elastic pads 23. In the drive assembly 31, the motor is installed in the outer cavity 313 of the extension plate 12, and its output shaft drives the gear 3102 to rotate. The meshing gears 3102 and the synchronous belt 3101 form a transmission system. The support tube in the middle of the synchronous belt 3101 prevents it from sagging and deforming. The surface of the synchronous belt 3101 is aligned with the assembly work... The surface of platform 1 is flush to ensure smooth sliding of assembly component 32; the bottom of the slide plate 321 of assembly component 32 is fixed to the synchronous belt 3101, the servo motor positioning groove 325 at the top fixes the servo motor, the limiting cavity 324 formed by the bending plate 322 and the side plate 323 can be adjusted according to the size of the slide body, the sweeping bar 5 on the side plate 323 cleans dust in advance and forms a dustproof space; when the drive component 31 operates and drives the slide plate 321 to slide, the sliding limiting rod 41 slides in the limiting groove 4 to ensure that the slide plate 321 moves smoothly in a straight line, and finally realizes the precise, efficient and dustproof automated docking assembly of the servo motor and the slide body.
