Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a lifting mechanical device of automation equipment. Background Art

[0002] Automation equipment refers to equipment that achieves automatic operation and control through mechanical, electronic, computer and other technologies to complete production, processing, assembly and other tasks, thereby improving production efficiency, reducing costs and improving product quality. There are many types of automation equipment, including automated robotic arms, automated conveying systems and automated packaging machinery. Lifting devices play an important role in automation equipment. Their influence is reflected in the fact that they can be used to adjust the working height or position of automation equipment to adapt to products of different specifications or the needs of different processes, thereby improving the flexibility and efficiency of the production line.

[0003] At present, the existing device (such as patent number: CN216303153U) discloses a lifting mechanical device of an automated device. The device can set a limit block, and when the output shaft of the lifting motor drives the adjusting screw to rotate to adjust the height of the lifting frame, the limit block can move up and down inside the limit groove, so that the lifting frame can be more stable when moving up and down, thereby improving the adaptability of the lifting mechanical device;

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the device only uses a single threaded transmission to lift the automated equipment, but if the automated equipment installed on the lifting frame is heavy, this will cause the friction force of the threaded connection between the lifting frame and the screw rod to be insufficient to offset the force of the load, making the actual height of the automated equipment on the lifting frame after lifting different from the expected height, which in turn affects subsequent processing. The practicality needs to be improved. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a lifting mechanical device for automated equipment, which solves the technical problem that the prior devices are insufficiently practical.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A lifting mechanical device of an automated device comprises a base, wherein a fixed block is symmetrically fixedly installed on the upper end of the base, a slide groove is provided inside the two fixed blocks, a slider is slidably installed inside the two slide grooves, and a lifting plate is fixedly installed between the two sliders;

[0010] A double self-locking mechanism is fixedly installed between the two fixing blocks;

[0011] The double self-locking mechanism includes a connecting block, which is located above the slide slot. The base and the connecting block are both provided with limited rotation slots. The double self-locking mechanism also includes a swivel, a lead screw, a worm gear, a support block, a motor and a worm.

[0012] Preferably: the two swivels are both located inside the limiting swivel groove, the two swivels are rotatably mounted with the limiting swivel groove, the screw rod is located between the swivels, the screw rod is fixedly mounted with the swivel ring, the screw rod is threadedly mounted with the lifting plate, and the worm gear is located on the circumferential surface of the screw rod.

[0013] Preferably: the worm gear is fixedly mounted on the lead screw, an automatic mechanical arm is symmetrically fixedly mounted on the upper end of the lifting plate, the two automatic mechanical arms are located on both sides of the lead screw, and the support block and the motor are located at the lower end of the connecting block.

[0014] Preferably: the support block and the motor are fixedly mounted with the connecting block, the worm is located on the output shaft of the motor, the worm is fixedly mounted with the motor, the worm is rotatably mounted with the support block, and the worm is meshingly mounted with the worm wheel.

[0015] (III) Beneficial effects

[0016] 1. Since the thread transmission itself has a certain self-locking property, and the meshing of the worm and the worm wheel also has self-locking property, the screw rod is indirectly driven to rotate by the meshing of the worm and the worm wheel, thereby completing double self-locking, which can effectively prevent the lifting plate from sinking on the screw rod due to the excessive weight of the automatic mechanical arm on the lifting plate, thereby affecting the processing accuracy of the automatic mechanical arm and improving practicality;

[0017] Second, by setting the rotating ring and the limiting rotating groove, when the worm and the worm wheel are engaged to drive the lead screw to rotate, the lead screw drives the rotating ring to rotate in the limiting rotating groove, thereby providing limitation and increasing stability.

[0024] The embodiment of the present application effectively solves the technical problem of insufficient practicality of the existing device by providing a lifting mechanical device for automated equipment. Since the threaded transmission itself has a certain self-locking property, and the meshing of the worm and the worm wheel also has a self-locking property, the screw rod is indirectly driven to rotate by the meshing of the worm and the worm wheel, thereby achieving double self-locking. This can effectively prevent the lifting plate from sinking on the screw rod due to the excessive weight of the automatic mechanical arm on the lifting plate, thereby affecting the processing accuracy of the automatic mechanical arm, thereby improving practicality. In addition, by setting a swivel and a limit groove, when the meshing of the worm and the worm wheel drives the screw rod to rotate, the screw rod drives the swivel to rotate in the limit groove, thereby providing a limit and increasing stability.

[0025] Example

[0026] like Figure 1-Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the existing device is not practical enough. The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a lifting mechanical device for automated equipment, comprising a base 11, a fixing block 12 is symmetrically fixedly installed on the upper end of the base 11, a slide groove 13 is provided inside the two fixing blocks 12, a slider 14 is slidably installed inside the two slide grooves 13, and a lifting plate 15 is fixedly installed between the two sliders 14;

[0028] A double self-locking mechanism is fixedly installed between the two fixing blocks 12;

[0029] The double self-locking mechanism includes a connecting block 16, which is located above the slide groove 13. The base 11 and the connecting block 16 are both provided with a limited rotation groove 17. The double self-locking mechanism also includes a swivel 18, a screw 19, a worm wheel 21, a support block 23, a motor 24 and a worm 25. Since the threaded transmission itself has a certain self-locking property, and the meshing of the worm 25 and the worm wheel 21 also has a self-locking property, double self-locking is achieved, and then the screw 19 is indirectly driven to rotate by the meshing of the worm 25 and the worm wheel 21, which can effectively prevent the lifting plate 15 from sinking on the screw 19 due to the excessive weight of the automatic mechanical arm 22 on the lifting plate 15, thereby affecting the processing accuracy of the automatic mechanical arm 22 and improving practicality.

[0030] The two swivels 18 are both located inside the limiting groove 17, and the two swivels 18 are both rotatably installed with the limiting groove 17. The screw 19 is located between the swivels 18, and the screw 19 is fixedly installed with the swivel 18. The screw 19 is threadedly installed with the lifting plate 15. The worm wheel 21 is located on the circumferential surface of the screw 19, and the worm wheel 21 is fixedly installed with the screw 19. An automatic mechanical arm 22 is symmetrically fixedly installed on the upper end of the lifting plate 15, and the two automatic mechanical arms 22 are both located on both sides of the screw 19. By setting the swivel 18 and the limiting groove 17, when the worm 25 and the worm wheel 21 are engaged to drive the screw 19 to rotate, the screw 19 drives the swivel 18 to rotate in the limiting groove 17, thereby providing limitation and increasing stability.

[0031] The support block 23 and the motor 24 are both located at the lower end of the connecting block 16, the support block 23 and the motor 24 are fixedly installed with the connecting block 16, the worm 25 is located on the output shaft of the motor 24, the worm 25 is fixedly installed with the motor 24, the worm 25 is rotatably installed with the support block 23, and the worm 25 is meshed with the worm wheel 21. By arranging the support block 23 under the connecting block 16, it can be used to assist in rotating and fixing the worm 25.

[0032] Working principle:

[0033] In the first step, when the height of the automatic mechanical arm 22 needs to be adjusted during use, the motor 24 can be turned on first, so that the motor 24 drives the worm 25 to rotate at the support block 23. At this time, the rotation of the worm 25 will mesh with the worm wheel 21, so that the worm wheel 21 generates a radial force;

[0034] In the second step, when the radial force of the worm gear 21 is generated, the worm gear 21 drives the screw rod 19 and the rotating ring 18 on the screw rod 19 to rotate between the limiting rotating groove 17. At the same time, the rotation of the screw rod 19 will generate threaded transmission with the lifting plate 15, so that the lifting plate 15 drives the slider 14 to slide upward in the sliding groove 13 in the fixed block 12, thereby driving the automatic mechanical arm 22 to adjust the height.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
