Description

Technical Field

[0001] The utility model belongs to the technical field of compressor production, and in particular relates to a servo linkage clamping mechanism applied to a compressor. Background Art

[0002] The compressor handling operation is involved in the process from production to packaging. At present, the industry mostly adopts the method of cylinder-driven clamping jaws. The power source is pneumatic clamping. The clamping force is easily affected by factory air pressure fluctuations. The clamping jaws are wedge clamping, and the clamping weight is limited. Therefore, the compressor is easy to fall during transportation.

[0003] It is known that from raw material steel to compressor, it goes through hundreds of processes to be assembled into a finished product. When the compressor falls, its performance needs to be retested, resulting in serious waste of operating resources and increased production costs.

[0004] In addition, compressors of different models have different outer diameters. When the compressor model is changed on the production line, the clamping jaws need to be replaced accordingly, resulting in problems such as long changeover time and low production capacity. Utility Model Content

[0005] In order to solve the shortcomings of the prior art, the utility model provides a servo-linked clamping mechanism applied to a compressor, which achieves constant clamping force and high clamping accuracy, enhances rigidity and stability, is suitable for clamping compressors with different outer diameters, does not require replacement of the clamping jaws, and improves line changing efficiency.

[0006] The technical purpose to be achieved by the utility model is achieved through the following technical solutions:

[0007] The utility model provides a servo linkage clamping mechanism applied to a compressor, comprising a motor drive module, a ball screw, a linkage plate, a mounting base plate and a plurality of linkage clamping modules;

[0008] The upper end of the ball screw is connected to the driving end of the motor drive module, the lower end of the ball screw passes through the mounting base plate, the linkage plate is installed in the middle of the ball screw, and a plurality of linkage clamping modules are evenly spaced and distributed along the circumference of the linkage plate;

[0009] The linkage clamping module comprises a connecting rod, a slide rail, a sliding mounting block and a clamping claw, wherein the slide rail is arranged on the mounting base plate, the sliding mounting block is slidably connected to the slide rail, and the lower end of the sliding mounting block passes through the mounting base plate and is connected to the clamping claw, one end of the connecting rod is connected to the linkage plate, and the other end of the connecting rod is connected to the sliding mounting block;

[0010] The ball screw moves downward, so that the clamping claws of the plurality of linkage clamping modules are moved closer to or farther from each other.

[0011] In some implementations, the number of the linkage clamping modules is three, and the three linkage clamping modules are evenly spaced along the circumference of the linkage plate, thereby providing a uniform and stable clamping effect on the compressor and improving the clamping consistency and clamping accuracy.

[0012] In some implementations, a buffer is connected to the side of the clamp that is in contact with the compressor to avoid hard contact between the clamp and the compressor, prevent damage to the clamp or the compressor, and improve the quality of the operation.

[0013] In some implementations, the buffer is made of plastic material, has elastic buffering effect, and is easy to process and shape.

[0014] In some implementations, a limit block is also connected to the middle of the ball screw, and the limit block is located at the lower end of the linkage plate. The limit block limits the maximum descent degree of the ball screw, thereby controlling the distance between the clamps to prevent over-driving of the motor drive module.

[0015] In some implementations, the sliding mounting block is a T-shaped structure, and each sliding mounting block corresponds to two sliding rails. The two sliding rails are respectively connected to the lower ends of the opposite sides of the sliding mounting block to ensure a more stable sliding action between the sliding mounting block and the sliding rails.

[0018] In some implementations, the motor drive module includes a motor drive assembly, a driving wheel, a driven wheel, and a synchronous belt;

[0019] The synchronous belt is sleeved on the outside of the driving wheel and the driven wheel, the driving wheel is connected to the driving end of the motor drive assembly, and the driven wheel is connected to the upper end of the ball screw. The linkage mode of the driving wheel, the driven wheel and the synchronous belt is adopted, which can reduce the height of the overall mechanism, make the center of gravity lower, and enhance the stability of the robot during the handling process.

[0020] In some implementations, the motor drive assembly includes a servo motor and a reducer, the driving end of the servo motor is connected to the reducer, and the driving end of the reducer is connected to the driving wheel. The reducer can increase the output torque of the servo motor and drive a larger load.

[0021] In summary, the utility model has at least the following benefits:

[0022] 1. The clamping mechanism provided by the utility model adopts servo system control to solve the problem that the traditional cylinder-driven clamping jaws are easily affected by factory air pressure fluctuations, so that the clamping force of each clamping jaw is constant and the clamping accuracy is high.

[0023] 2. Compared with the wedge clamping form of the traditional cylinder clamp, the clamping mechanism provided by the utility model adds a slide rail to play a guiding role, and also enhances the rigidity and stability.

[0024] 3. The clamping mechanism provided by the utility model is suitable for clamping compressors with different outer diameters, and there is no need to replace the clamping jaws, thereby improving the line changing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1:

[0041] See also Figure 1 A servo linkage clamping mechanism applied to a compressor adopts a servo system control to stably clamp and carry the compressor, including a motor drive module 100, a ball screw 200, a linkage plate 300, a mounting base plate 400 and a plurality of linkage clamping modules 500.

[0042] The motor drive module 100 is used to play a driving role, and the ball screw 200 plays a transmission role in the driving effect of the motor drive module 100. The linkage plate 300 can link multiple linkage clamping modules 500 to produce state changes under the movement of the ball screw 200, and the installation base plate 400 is used for the installation of multiple linkage clamping modules 500.

[0043] The upper end of the ball screw 200 is connected to the driving end of the motor drive module 100, and the lower end of the ball screw 200 passes through the mounting base plate 400. That is, a first through hole for the lower end of the ball screw 200 to pass through is opened on the mounting base plate 400, so that the ball screw 200 can move downward or upward toward the mounting base plate 400 under the driving action of the motor drive module 100.

[0044] The linkage plate 300 is installed in the middle part of the ball screw 200, and multiple linkage clamping modules 500 are evenly spaced along the circumference of the linkage plate 300. The linkage clamping module 500 includes a connecting rod 510, a slide rail 520, a sliding mounting block 530 and a clamping claw 540. The slide rail 520 is arranged on the mounting base plate 400, and the sliding mounting block 530 is slidably connected to the slide rail 520, and the lower end of the sliding mounting block 530 passes through the mounting base plate 400 and is connected to the clamping claw 540, that is, a second through hole for the lower end of the sliding mounting block 530 to pass through is opened on the mounting base plate 400, one end of the connecting rod 510 is connected to the linkage plate 300, and the other end of the connecting rod 510 is connected to the sliding mounting block 530, and the ball screw 200 moves downward, so that the clamping claws 540 of the multiple linkage clamping modules 500 are close to or away from each other.

[0045] For example, the connecting rod 510 is arranged obliquely, and with the connection between the connecting rod 510 and the linkage plate 300 as a reference, the connecting rod 510 is inclined outward and downward relative to the connection, and its other end is connected to the sliding mounting block 530. In this way, during the downward movement of the rolling screw, the connecting rod 510 can be driven to move outward and downward, and the outward and downward movement changes acting on the connecting rod 510 are transferred to the sliding mounting block 530, which is presented as the sliding mounting block 530 moving horizontally on the slide rail 520.

[0046] Specifically, when the motor drive module 100 drives the ball screw 200 to move downward, the linkage plate 300 also moves downward accordingly, and the connecting rod 510 moves outward and downward. At this time, the linkage sliding mounting block 530 moves laterally on the slide rail 520. Since the lower end of the sliding mounting block 530 is connected to the clamping claw 540, it is equivalent to changing the position of the clamping claw 540. In this embodiment, one end of the slide rail 520 is toward the middle of the mounting base 400, and the other end of the slide rail 520 is distributed toward the edge of the mounting base 400. In this way, when the motor drive module 100 drives the ball screw 200 to move downward, it can link each sliding mounting block 530 to move toward the edge of the mounting base 400 on each slide rail 520, so that each clamping claw 540 moves away from each other; similarly, when the motor drive module 100 drives the ball screw 200 to move upward, it can link each sliding mounting block 530 to move toward the middle of the mounting base 400 on each slide rail 520, so that each clamping claw 540 approaches each other, that is, clamps the compressor.

[0047] It can be understood that the clamping mechanism provided in this embodiment is not only used for clamping and transporting compressors, but also for clamping and transporting columnar structure products. By adopting servo system control, the problem that traditional cylinder-driven jaws are easily affected by factory air pressure fluctuations is solved, so that the clamping force of each jaw is constant and the clamping accuracy is high; compared with the wedge clamping form of traditional cylinder jaws, a slide rail is added to play a guiding role, and at the same time the rigidity and stability are also enhanced; it is suitable for clamping compressors with different outer diameters, without the need to replace the jaws, thereby improving the line change efficiency.

[0048] Embodiment 2:

[0049] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the clamping mechanism of the utility model, see Figure 2 .

[0050] There are three linkage clamping modules 500 , which are evenly spaced and distributed along the circumference of the linkage plate 300 , so as to provide uniform and stable clamping for the compressor and improve the clamping stability and clamping accuracy.

[0051] The three linkage clamping modules 500 can be driven by the motor driving module 100 and linked by the connecting rod 510 , so that the clamping claws 540 thereof move away from or close to each other, thereby releasing or clamping the compressor.

[0052] A buffer 600 is connected to the side of the clamp 540 that contacts the compressor. The buffer 600 can play a clamping and buffering role to avoid hard contact between the clamp 540 and the compressor, prevent damage to the clamp 540 or the compressor, and improve the quality of the operation.

[0053] The buffer member 600 is made of plastic material, which has elastic buffering effect and is easy to process and shape.

[0054] In some embodiments, the middle part of the ball screw 200 is also connected to a limit block 700, which is located at the lower end of the linkage plate 300. The limit block 700 limits the maximum descent degree of the ball screw 200, thereby controlling the distance between the clamps 540 and preventing over-driving of the motor drive module 100.

[0055] It can be understood that when the ball screw 200 moves downward a certain distance under the drive of the motor drive module 100, when the limit block 700 contacts the mounting base 400, it means that the ball screw 200 has descended to the lowest position, that is, the motor drive module 100 has been driven into place, and the maximum spacing is presented between each clamping jaw 540.

[0056] In some embodiments, the sliding mounting block 530 is a T-shaped structure, and each sliding mounting block 530 corresponds to two sliding rails 520. The two sliding rails 520 are respectively connected to the lower ends of the opposite sides of the sliding mounting block 530, ensuring a more stable sliding action between the sliding mounting block 530 and the sliding rails 520. The lower end of the sliding mounting block 530 passes through the mounting base plate 400 and is connected to the clamp 540, which plays a stable linkage role on the clamp 540.

[0057] Embodiment 3:

[0058] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the clamping mechanism of the utility model, see Figure 3 and Figure 4 .

[0059] The clamping mechanism also includes an installation top plate 800, and a plurality of connecting columns are arranged between the installation top plate 800 and the installation bottom plate 400. For example, the number of the connecting columns is six, and the six connecting columns are distributed at intervals, and one end of each connecting column is connected to the installation top plate 800, and the other end of each connecting column is connected to the installation bottom plate 400. The motor drive module 100 is arranged on the installation top plate 800, and the motor drive module 100 is installed and fixed by installing the top plate 800 to improve the consistency of overall use.

[0060] In some embodiments, the clamping mechanism further includes a manipulator 900, a driving end of the manipulator 900 is connected to the mounting top plate 800, and the manipulator 900 is used to drive the clamping direction to achieve the effect of automatically transporting the compressor.

[0061] For example, the robot 900 drives each gripper 540 to move to the production line. After each gripper 540 clamps the compressor, the robot 900 drives each gripper 540 to clamp the compressor and move it to the packaging line. Each gripper 540 then releases the compressor to achieve automated handling operations.

[0062] In some embodiments, the motor drive module 100 includes a motor drive assembly 110, a driving wheel 120, a driven wheel 130 and a synchronous belt 140; the synchronous belt 140 is sleeved on the outside of the driving wheel 120 and the driven wheel 130, the driving wheel 120 is connected to the driving end of the motor drive assembly 110, and the driven wheel 130 is connected to the upper end of the ball screw 200. The linkage mode of the driving wheel 120, the driven wheel 130 and the synchronous belt 140 can reduce the height of the overall mechanism, make the center of gravity lower, and enhance the stability of the manipulator 900 during the handling process.

[0063] Specifically, the driving wheel 120 is driven by the motor drive assembly 110 and rotates in conjunction with the driven wheel 130 through the synchronous belt 140 , and the ball screw 200 converts the rotation of the driven wheel 130 into linear movement, thereby presenting a downward or upward movement effect.

[0064] In some embodiments, the motor drive assembly 110 includes a servo motor 111 and a reducer 112, the driving end of the servo motor 111 is connected to the reducer 112, and the driving end of the reducer 112 is connected to the driving wheel 120. The reducer 112 can increase the output torque of the servo motor 111 and drive a larger load to adapt to the clamping requirements of more models of compressors with different weights, thereby improving the clamping stability and versatility.

[0065] The servo-linked clamping mechanism of the utility model applied to the compressor adopts servo system control to solve the problem that the traditional cylinder-driven clamping jaws are easily affected by factory air pressure fluctuations, so that the clamping force of each clamping jaw is constant and the clamping accuracy is high; compared with the wedge clamping form of the traditional cylinder clamping jaws, a slide rail is added to play a guiding role, and the rigidity and stability are also enhanced; it is suitable for clamping compressors with different outer diameters, and there is no need to replace the clamping jaws, thereby improving the line change efficiency.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0068] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
