Description

Technical Field

[0001] The invention belongs to the technical field of lightweight processing equipment, and in particular relates to a lightweight and compact double-motor common rail parallel motion mechanism. Background Art

[0002] In various current mechanical motion systems, the design and performance requirements for motion mechanisms are constantly increasing. Among them, traditional single-moving sub-motion mechanisms have gradually exposed many limitations in some complex application scenarios. In some precision instruments and miniaturized production equipment with extremely demanding space utilization and other similar equipment, single-moving sub-mechanisms cannot meet the needs of efficient movement of multiple components at the same time.

[0003] To this end, existing solutions provide a multi-motor motion mechanism to meet the needs of efficient simultaneous movement of multiple components; however, some existing multi-motor motion mechanisms often adopt a more complex layout and structural design, which not only increases the overall weight and makes the overall equipment bloated, but also makes it difficult to flexibly expand and adjust the multi-motor motion mechanism, greatly limiting the scalability of the equipment, and is not conducive to the lightweight and compact design of the equipment. It gradually deviates from or is even unsuitable for precision instruments and miniaturized production equipment that are extremely demanding on space utilization.

[0004] In summary, the existing multi-motor motion mechanism still has problems in terms of structural complexity, weight, space utilization and scalability. At present, there is an urgent need for a double-motor common rail motion mechanism with simple structure, light weight and compactness, high scalability and space utilization. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a lightweight and compact double-mover common rail parallel motion mechanism to solve the problems that still exist in the prior art multi-mover motion mechanism in terms of structural complexity, weight, space utilization and scalability.

[0006] One solution of the present invention provides a lightweight and compact double-motor common rail parallel motion mechanism, comprising a motor track, a common rail motor group, a tool mounting assembly and a connecting assembly, wherein the tool mounting assembly is mounted on the common rail motor group through the connecting assembly, and the common rail motor group is movably connected to the motor track;

[0007] The common rail motor group includes at least two common rail motors, each of which is connected to the connecting assembly;

[0008] The common rail motor group is used to control the position of the common rail motor on the motor track to control the working state of the connection component; the connection component is used to change the working state according to the position of the common rail motor on the motor track to control the working state of the tool installation component; the tool installation component is used to install the processing tool and change the working state synchronously when the working state of the connection component changes;

[0009] It should be noted that the common rail motor group is connected to an external energy supply device, which directly supplies energy to each common rail motor in the common rail motor group to control the position of each common rail motor on the motor track;

[0010] It should be additionally explained that the working states of the connection assembly and the tool installation assembly at least include the moving direction, moving distance and posture. In actual use, the working state of the connection assembly will change in real time according to the position of each common rail motor on the motor guide rail, and then the working state of the tool installation assembly will be controlled according to different working states; the specific structure of the connection assembly and the working principle between the common rail motor group, the connection assembly and the tool installation assembly in actual use are described in detail below and will not be repeated here;

[0011] It should be further explained that, in actual use, the number of common rail motors in the common rail motor group and the specific structure of the connecting assembly can be expanded according to processing requirements. Specifically, the staff can install common rail motors on the motor track, install the motor mounting shaft in the connecting assembly on the added common rail motor, install the tool mounting shaft in the connecting assembly on the tool mounting assembly, and install a connecting rod between the added tool mounting shaft and the added motor mounting shaft according to actual processing requirements, so as to increase the number of tool mounting assemblies and the adjustable range of inclination of each tool mounting assembly, etc.

[0012] In this solution, on the one hand, by controlling the position distribution of the common rail motor in the common rail motor group on the electric guide rail, the specific working state of the connecting component is controlled, and finally the moving direction and distance of the tool installation component are controlled by the specific working state of the connecting component. On the other hand, through the structure of the motor track, the common rail motor group, the tool installation component and the connecting component, a lightweight and compact double-motor common rail parallel motion mechanism with simple structure, relatively light weight, high space utilization and strong expansibility is provided;

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The present invention can ensure the stable movement of the common rail motor in the common rail motor group on the motor track through the cooperation between the motor track and the common rail motor group, thereby ensuring the stable movement of the connecting assembly that moves synchronously with the common rail motor and the stable movement of the tool mounting assembly installed on the connecting assembly, providing a guarantee for the stable processing of the processing tool on the tool mounting assembly, and on the other hand, realizing the coordinated movement of multiple movers in a limited space, so that multiple common rail motors can move on the motor track at the same time, improving the space utilization rate and avoiding the waste of space on the basis of satisfying the simultaneous and efficient movement of multiple components, and being more suitable for precision instruments and miniaturized production equipment with extremely demanding space utilization;

[0015] 2. The present invention can control the position of each common rail motor on the motor track according to actual processing requirements through the cooperation of the common rail motor group and the connecting component, and then quickly adjust the working state of the connecting component, and finally realize the motion control of the tool installation component. In addition, the staff can expand the common rail motor rent and the connecting component according to the actual processing requirements to realize the diversified working state control of the tool installation component by controlling the position of each common rail motor on the click track, which is more expandable and practical;

[0016] 3. The present invention forms a simple, lightweight and compact motion mechanism through the coordination of the motor track, the common rail motor group, the tool mounting assembly and the connecting assembly. The connection and cooperation between the components are simple. Compared with the complex layout and structural design of the existing multi-motor motion mechanism, the present invention has no complex intermediate transmission links and redundant structures, which greatly reduces the overall weight and makes the equipment more compact.

[0017] In one embodiment, the common rail motor comprises a motor mover and a motor stator, and the common rail motor is movably connected to the motor track via the motor mover;

[0018] The motor stator is used to generate a traveling wave magnetic field when the common rail motor is powered on, and then the traveling wave magnetic field interacts with the permanent magnet magnetic field to provide power for the motor mover to move on the motor track; the motor mover is used to provide a permanent magnet magnetic field and move along the motor track under the interaction of the traveling wave magnetic field and the permanent magnet magnetic field;

[0019] It should be noted that the motor mover is a permanent magnet, and a winding is arranged inside the motor stator. When the common rail motor is energized, the current passes through the winding, generating a traveling wave magnetic field, which interacts with the permanent magnetic field of the permanent magnet, thereby driving the motor mover to move on the motor track.
