Description

Technical Field

[0001] The present invention relates to the technical field of electric cylinder installation, and in particular to an electric cylinder installation and fixing structure. Background Art

[0002] An electric cylinder is a linear actuator driven by an electric motor that converts rotary motion into linear motion. Compared to traditional hydraulic or pneumatic cylinders, it offers higher control accuracy, more stable performance, and a simpler design. It is widely used in industrial automation, particularly in applications requiring precise positioning and high repeatability.

[0003] The prior art publication number CN222735938U provides an electric cylinder installation and fixing structure. Through the limiting ears at the bottom of the clamp and the adjusting rod in the middle, the end clamp can be clamped and fixed, and manual control facilitates installation and disassembly; one side of the electric cylinder is connected to the pad through a hoop plate, and the mounting ears on the pad move up and down in the waist groove through the locking ears at both ends, which can be adjusted according to the installation position, and can be quickly fixed to the electric cylinder through the hoop plate.

[0004] Load-erecting equipment often uses two electric cylinders, one on each side, working in tandem. The extension phase represents the erection process, while the retraction phase represents the lowering process. Due to operational requirements, these two cylinders must operate synchronously. Traditional control methods utilize two separate servo motors and transmission mechanisms, which can lead to equipment damage due to asynchrony. Improving synchronization requires adding additional motors or employing software-based compensation control, which increases costs and creates a bulky structure.

[0005] In addition, when the electric cylinder works under large load or long stroke conditions, the piston rod may be affected by lateral force during the extension and retraction process. The existing technology lacks effective support, which can easily cause the piston rod to bend and deform, affecting the accuracy and service life of the electric cylinder.

[0006] In summary, the existing technology lacks auxiliary support technology for the piston rod of the electric cylinder. Summary of the Invention

[0024] like Figure 2As shown, two mounting brackets 101 are symmetrically fixedly attached to the mounting base 1. The mounting brackets 101 are rotatably connected to the bottom end of the electric cylinder 6. The mounting brackets 101 are provided with left and right support brackets that are sleeved onto the outer surface of the base of the electric cylinder 6. A motor base 102 is fixedly attached to the mounting base 1 and is fixedly connected to the servo motor 2. The electric cylinder 6 can be rotated on the mounting brackets 101 to adjust to a suitable angle and then locked with the clamps on the support brackets.

[0025] like Figure 2 As shown, the lead screws in the left and right electric cylinders 6 are respectively a left-handed lead screw and a right-handed lead screw.

[0026] like Figure 3 As shown, the transmission shaft 5 is transmission-connected to the reducer in the electric cylinder 6 , and transmission wheels 501 are fixedly connected at both ends of the transmission shaft 5 .

[0027] like Figure 4 As shown, bearings 701 are fixedly connected to both ends of the reinforcement frame 7 , and the bearings 701 are fixedly connected to the top end of the piston rod of the electric cylinder 6 .

[0028] like Figure 5 As shown, the following mechanism 8 includes two fixed seats 801, the fixed seat 801 is fixedly connected to the mounting base 1, a turntable 802 is rotatably connected to the middle part of the fixed seat 801, the turntable 802 is fixedly connected to the transmission shaft 5, a worm 803 is rotatably connected on the turntable 802, one end of the worm 803 is fixedly connected to a gear plate 804, the gear plate 804 is meshed with the transmission wheel 501 for transmission, a worm wheel 805 is meshed with the transmission wheel 501 on one side of the worm 803, a strut group 806 is fixedly connected to the worm wheel 805, the bottom end of the strut group 806 is rotatably connected to the turntable 802, the top of the strut group 806 is rotatably connected to a hinge seat 807, and the hinge seat 807 is fixedly connected to the reinforcement frame 7. When the transmission shaft 5 rotates, the connected transmission wheel 501 will drive the gear plate 804 to rotate, so that the gear plate 804 can drive the worm 803 to rotate, so that the worm 803 drives the support rod group 806 connected to the worm wheel 805 to rotate, so that the support rod group 806 drives the reinforcement frame 7 to move following the piston rod of the electric cylinder 6.

[0029] A reinforcement frame 7 is attached to the piston rod of the electric cylinder 6. Driven by a follower mechanism 8, the reinforcement frame 7 moves with the piston rod, effectively supporting the piston rod and reducing its bending deformation. This also improves motion stability, load-bearing capacity, and structural strength. This significantly enhances the performance, precision, and reliability of the electric cylinder 6 system, extending its service life and being particularly effective in high-load, high-precision applications.

[0030] like Figure 6As shown, a sleeve rod 1001 is fixedly connected to one end of the maintenance scraper 10. A sleeve hole 901 is formed on the bottom surface of one side of the rotating sleeve 9. The top of the sleeve rod 1001 is slidably engaged with the inner wall of the sleeve hole 901. A spring 1002 is fixedly connected to the top of the sleeve rod 1001. The other end of the spring 1002 is fixedly connected to the inner wall of the sleeve hole 901. The side and bottom edges of the maintenance scraper 10 are respectively in sliding contact with the piston rod of the electric cylinder 6 and the top of the electric cylinder 6. When the rotating sleeve 9 rotates, it drives the maintenance scraper 10 to rotate. At this time, under the action of the spring 1002, the maintenance scraper 10 connected to the sleeve rod 1001 scrapes and cleans the lubricating oil on the outer wall of the piston rod of the electric cylinder 6.

[0031] like Figure 6 、 Figure 7 As shown, the transmission mechanism 11 includes a fixed frame 1101, one end of which is fixedly connected to the reinforcement frame 7.

The transmission rack 1204 drives the driving pulley 1104 to rotate, which in turn drives the universal joint 1102 to rotate, causing the universal joint 1102 to drive the connected driven pulley 1103 to rotate, which in turn drives the rotating sleeve 9 to which the driven pulley 1103 is connected to rotate.

[0032] like Figure 8 As shown, the inclined surface of the trigger triangle 12 is in sliding contact with the outer wall of the top end of the electric cylinder 6.

The transmission rack 1204 engages with the driving wheel 1104 for transmission. When the inclined surface of the trigger triangle 12 contacts the electric cylinder 6, it pushes the trigger triangle 12 to move, causing the trigger triangle 12 to move the transmission rack 1204 connected to the sliding frame 1201. The tension spring 1203 automatically resets the trigger triangle 12.

[0033] Working principle: When the load needs to be erected, the servo motor 2 is energized to drive the planetary reducer 4, which is then transmitted to the gear box 3 and output to the transmission shafts 5 at both ends through gear rotation. The transmission shafts 5 rotate to drive the electric cylinder 6, which is then connected to the reducer and transmitted to the lead screw. The lead screw drives the nut to extend the piston rod. The servo motor 2 reverses and similarly completes the lowering action. A single servo motor 2 is used to drive the electric cylinder 6 connected to the gear box 3 and the transmission shaft 5, replacing the traditional two sets of independently controlled transmission systems. While achieving synchronous, reliable and precise control, the overall structure is more streamlined and compact than the traditional two sets of control structures, which can meet the installation forms and space requirements of more equipment, achieving multiple results at one stroke. At the same time, when the transmission shaft 5 rotates, the connected transmission wheel 501 drives the toothed disc 804 to rotate, so that the toothed disc 804 can drive the worm 803 to rotate, so that the worm 803 drives the support rod group 806 connected to the worm wheel 805 to rotate, so that the support rod group 806 drives the reinforcement frame 7 to move along with the piston rod of the electric cylinder 6; Then, when the piston rod of the electric cylinder 6 moves downward to reset, when the inclined surface of the trigger triangular plate 12 contacts the electric cylinder 6, it pushes the trigger triangular plate 12 to move, so that the trigger triangular plate 12 drives the transmission rack 1204 connected to the sliding frame 1201 to move, so that the transmission rack 1204 drives the driving wheel 1104 to rotate. At this time, the driving wheel 1104 drives the universal joint 1102 to rotate, so that the universal joint 1102 drives the connected driven wheel 1103 to rotate, so that the driven wheel 1103 drives the rotating sleeve 9 connected to the driven wheel 1103 to rotate. When the piston rod of the electric cylinder 6 moves upward, the trigger triangular plate 12 will no longer contact the electric cylinder 6. At this time, under the action of the tension spring 1203, the trigger triangular plate 12 will automatically reset, which is convenient for the next use. Then when the rotating sleeve 9 rotates, it will drive the maintenance scraper 10 to rotate. At this time, under the action of the spring 1002, the maintenance scraper 10 connected to the sleeve rod 1001 will scrape off the lubricating oil with dust on the outer wall of the piston rod of the electric cylinder 6.
