Description

Technical Field

[0001] This utility model relates to the field of servo electric cylinder dual-axis robotic arm technology, and particularly to servo electric cylinder dual-axis robotic arm. Background Technology

[0002] The servo-electric cylinder dual-axis robotic arm is an automated robotic arm device driven by servo motors and electric cylinders. It has two independent motion axes, enabling precise motion control in a plane. Combining the high-precision control capability of a servo system with the high-load characteristics of an electric cylinder, it is a high-precision, high-load automated device. Driven by servo motors and electric cylinders, and combined with a dual-axis structure and control system, it can achieve complex motion trajectories and is widely used in many fields.

[0003] In actual use, the following shortcomings were found in this device:

[0004] Because the pneumatic actuator is constantly operating at its maximum stroke limit, it generates periodic impact loads, which severely reduces the lifespan of the solenoid valve assembly compared to the standard operating conditions. The lifting terminal buffer system is only equipped with a single-stage rubber shock absorber, which has insufficient kinetic energy absorption rate, resulting in large transient impact noise. The pressure plate is prone to tilting when fingers grip it.

[0005] Therefore, this application provides a servo-electric cylinder dual-axis robotic arm to meet the requirements. Utility Model Content

[0013] Preferably, a lifting electric cylinder is provided in the middle of the electric cylinder push plate, and the bottom output end of the lifting electric cylinder passes through the electric cylinder push plate and the first base plate and is fixedly connected to the finger cylinder mounting plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1 , Figure 2 as well as Figure 3 The servo-electric cylinder dual-axis robotic arm shown includes: a base 1, a first base plate 2 fixed to the top of the base 1 by bolts, a transverse electric cylinder 3 fixed to the top of the first base plate 2 by bolts, two linear slide rails 7 symmetrically arranged on both sides of the top of one end of the first base plate 2, an electric cylinder push plate 4 arranged on the top of the two linear slide rails 7, a second base plate 5 arranged on the top of one side of the electric cylinder push plate 4, and guide slides 26 adapted to the bottom of both sides of the electric cylinder push plate 4 corresponding to the positions of the linear slide rails 7.

[0030] The output end of the transverse electric cylinder 3 is fixedly connected to the electric cylinder push plate 4.

[0031] A drag chain 6 is provided at the top front end of the electric cylinder push plate 4, and one bottom end of the drag chain 6 passes through the first base plate 2 and the electric cylinder push plate 4.

[0032] The top of the electric cylinder push plate 4 is provided with a soft limit 8 and a hard limit 9. A U-shaped block 13 is provided above the electric cylinder push plate 4. Lifting guide rods 11 are provided on both sides of the bottom of the U-shaped block 13. The bottom end of the lifting guide rod 11 passes through the electric cylinder push plate 4 and the first base plate 2. The bottom end of the lifting guide rod 11 is fixedly connected to the finger cylinder mounting plate 14. A first linear bearing 10 is sleeved on the outside of the position where the lifting guide rod 11 passes through the electric cylinder push plate 4.

[0033] Using base 1 as a supporting foundation, the crossbeam area of ​​the raised section of base 1 has been structurally reinforced, and a through hole is provided at the bottom for secure connection to external equipment via bolts. The top of the raised section of base 1 is equipped with a first base plate 2, on which a transverse electric cylinder 3 and a linear slide rail 7 are integrated. A movable second base plate 5 is mounted on the surface of the linear slide rail 7. During system initialization, the transverse electric cylinder 3 is in the extended position. The lifting electric cylinder 12 mounted on it drives the finger cylinder mounting plate 14, finger cylinder 15, self-made finger 16, and pressure plate 18 to perform vertical movement through a guide system consisting of U-shaped block 13, lifting guide rod 11, and first linear bearing 10. When the self-made finger 16 grasps the pressure plate 18, it connects to the pressure plate 18 through square pin 17. The grooves constrain the pressure plate 18 to prevent it from flipping. After the equipment completes internal processing, the push-pull cylinder 20 on the base 1 starts to retract, causing the sealing plate 24 to move and open the top opening of the equipment. When the lifting cylinder 12 performs the pressing action, the U-shaped block 13 connected to the lifting guide rod 11 first contacts the two soft limiters 8. The soft limiters 8 adopt a hydraulic buffer mechanism and rubber contact surface design, which can significantly reduce the impact of movement and reduce noise. When the soft limiters 8 drop to the same height as the adjusting bolt of the hard limiter 9, the lifting cylinder 12 reaches the preset position. By adjusting the height of the bolt of the hard limiter 9, the clamping and positioning of the pressure plate 18 can be precisely controlled. The application of the first linear bearing 10 effectively suppresses the swaying problem of the lifting guide rod 11 during the movement.

[0034] In this embodiment, as Figures 1-3As shown; a lifting electric cylinder 12 is provided in the middle of the electric cylinder push plate 4, and the bottom output end of the lifting electric cylinder 12 passes through the electric cylinder push plate 4 and the first base plate 2 and is fixedly connected to the finger cylinder mounting plate 14.

[0035] Two finger cylinders 15 are symmetrically arranged at the bottom of the finger cylinder mounting plate 14. A self-made finger 16 is fixed at the bottom of each finger cylinder 15. A square pin 17 is provided on one side of the self-made finger 16, and a pressure plate 18 is provided at the front end of the self-made finger 16.

[0036] A cylinder mounting bracket 19 is provided at the top of one end of the base 1, and a push-pull cylinder 20 is provided in the middle of the cylinder mounting bracket 19. One end of the push-pull cylinder 20 passes through one end of the cylinder mounting bracket 19 and is fixedly connected to a sealing plate mounting bracket 21.

[0037] The front end of the sealing plate mounting bracket 21 is provided with a sealing plate 24. Two transverse guide rods 25 are symmetrically arranged on both sides of the bottom of the base 1, corresponding to the positions on both sides of the sealing plate 24. Both ends of the transverse guide rods 25 are fixedly connected to guide rod mounting blocks 22. The top of the guide rod mounting blocks 22 is fixedly connected to the base 1. A second linear bearing 23 is sleeved on the outer side of the transverse guide rods 25.

[0038] When the lifting cylinder 12 reaches the lower limit, the descent sensor at its end triggers a signal, driving the horizontal cylinder 3 to retract, causing the pressure plate 18 to move towards the workpiece. After the workpiece is fixed, the finger cylinder 15 releases its clamping state, and the horizontal cylinder 3 returns to the extension position and sends a feedback signal through the sensor. Then, the lifting cylinder 12 rises to the upper limit and sends a signal to the push-pull cylinder 20, driving it to extend so that the sealing plate 24 closes the equipment opening, preventing processing debris from splashing. By cyclically executing the above process, the system achieves fully automatic gripping and clamping of the pressure plate 18.

[0039] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
