Description

Technical Field

[0001] This invention relates to the field of electric cylinder installation technology, and in particular to an electric cylinder installation and fixing structure. Background Technology

[0002] An electric cylinder is a linear actuator driven by an electric motor, used to convert rotary motion into linear motion. Compared with traditional hydraulic or pneumatic cylinders, it has higher control precision, more stable performance, and a simpler design, and is widely used in industrial automation, especially suitable for applications requiring precise positioning and high repeatability.

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

[0004] In load-lifting equipment, two electric cylinders, one on the left and one on the right, often work together. Their extension is the lifting process, and their retraction is the lowering process. Due to operational requirements, the two electric cylinders must move synchronously. Traditional control methods use two sets of servo motors and transmission mechanisms to drive the equipment separately, which may lead to damage due to asynchrony. Improving synchronization requires adding extra motors or using software compensation control, resulting in increased costs and a bulky structure.

[0005] Furthermore, when the electric cylinder operates under heavy load or long stroke conditions, the piston rod may be affected by lateral forces during the extension and retraction process. Existing technology lacks effective support, which can easily lead to bending and deformation of the piston rod, affecting the accuracy and service life of the electric cylinder.

[0006] In summary, existing technologies lack auxiliary support technology for the piston rod of electric cylinders. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of the prior art by proposing an electric cylinder mounting and fixing structure.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an electric cylinder mounting and fixing structure, including a mounting base, a servo motor fixedly mounted on the mounting base, a gearbox fixedly connected to the mounting base, a planetary reducer fixedly mounted on one side of the gearbox, the gearbox being connected to the servo motor through the planetary reducer, transmission shafts mounted on both sides of the gearbox, one end of the transmission shaft being connected to an electric cylinder with a lead screw and a reducer, a reinforcing frame mounted above the mounting base, a following mechanism mounted below the reinforcing frame, rotating sleeves rotatably connected to both ends of the reinforcing frame, maintenance scrapers mounted on the rotating sleeves, a transmission mechanism fixedly connected to both ends of the reinforcing frame, and a trigger triangle plate mounted on one side of the transmission mechanism.

[0009] Preferably, the mounting base has two mounting brackets fixedly connected in a symmetrical structure. The mounting brackets are rotatably connected to the bottom of the electric cylinder. The mounting brackets are provided with two left and right clamps that fit onto the outer surface of the electric cylinder base. The mounting base has a motor mount fixedly connected to it, and the motor mount is fixedly connected to a servo motor.

[0010] Preferably, the lead screws in the left and right electric cylinders are left-handed lead screws and right-handed lead screws, respectively.

[0011] Preferably, the drive shaft is connected to the reducer inside the electric cylinder, and drive wheels are fixedly connected to both ends of the drive shaft.

[0012] Preferably, bearings are fixedly connected to both ends of the reinforcing frame, and the bearings are fixedly connected to the top end of the piston rod of the electric cylinder.

[0013] Preferably, the following mechanism includes two fixed seats, which are fixedly connected to the mounting base. A turntable is rotatably connected to the middle of the fixed seat, and the turntable is fixedly connected to the transmission shaft. A geared disc is connected to one side of the fixed seat, and a worm gear is rotatably connected to the geared disc. The geared disc meshes with a transmission wheel. A worm wheel meshes with one side of the worm gear, and a support rod assembly is fixedly connected to the worm wheel. The bottom end of the support rod assembly is rotatably connected to the turntable, and a hinge seat is rotatably connected to the top end of the support rod assembly. The hinge seat is fixedly connected to the reinforcing frame.

[0014] Preferably, a sleeve rod is fixedly connected to one end of the maintenance scraper, a sleeve hole is opened on one bottom side of the rotating sleeve, the top end of the sleeve rod is slidably engaged with the inner wall of the sleeve hole, a spring is fixedly connected to the top end of the sleeve rod, the other end of the spring is fixedly connected to the inner wall of the sleeve hole, and the side and bottom edges of the maintenance scraper are slidably in contact with the piston rod and the top end of the electric cylinder, respectively.

[0015] Preferably, the transmission mechanism includes a fixed frame, one end of which is fixedly connected to a reinforcing frame, a universal joint is rotatably connected to the fixed frame, a driven wheel is fixedly connected to one end of the universal joint, a gear ring is fixedly connected to the rotating sleeve, the gear ring meshes with the driven wheel for transmission, and a driving wheel is fixedly connected to the other end of the universal joint.

[0016] Preferably, the inclined surface of the trigger triangle plate is slidably in contact with the outer wall of the top of the electric cylinder. A sliding frame is fixedly connected to the trigger triangle plate. A fixed rod is slidably fitted on the sliding frame. The fixed rod is fixedly connected to the reinforcing frame. A tension spring is fixedly connected to the fixed rod. The other end of the tension spring is fixedly connected to the sliding frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] A reinforcing frame is installed on the piston rod of the electric cylinder. This frame moves with the piston rod under the action of a following mechanism, effectively assisting in supporting the piston rod and reducing its bending deformation. Simultaneously, it improves motion stability, enhances load-bearing capacity, and strengthens the structure. This significantly improves the working performance, accuracy, and reliability of the electric cylinder system, extends its service life, and is particularly effective in high-load, high-precision applications.

[0019] A maintenance scraper is installed on the rotating sleeve of the reinforcing frame. When the reinforcing frame moves down close to the electric cylinder, the maintenance scraper rotates around the sliding part between the top of the electric cylinder and the piston rod under the action of the trigger triangle plate and the transmission mechanism. This cleans the lubricating oil mixed with dust, reduces the wear of impurities on the moving parts inside the electric cylinder, and extends the service life of the electric cylinder and other core components such as the piston rod.

[0020] The transmission mechanism, which uses a single servo motor to drive the gearbox and drive shaft, replaces the traditional two independently controlled transmission systems. While achieving synchronous, reliable and precise control, the overall structure is more streamlined and compact than the traditional two-set control structure, which can meet the installation forms and space requirements of more equipment, achieving multiple benefits.

[0030] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0031] like Figures 1-8The electric cylinder mounting and fixing structure shown includes a mounting base 1, a servo motor 2 fixedly mounted on the mounting base 1, a gearbox 3 fixedly connected to the mounting base 1, a planetary reducer 4 fixedly mounted on one side of the gearbox 3, and the gearbox 3 connected to the servo motor 2 via the planetary reducer 4. Drive shafts 5 are mounted on both sides of the gearbox 3, one end of each drive shaft 5 connected to an electric cylinder 6 equipped with a lead screw and a reducer. A reinforcing frame 7 is mounted above the mounting base 1, and a following mechanism 8 is mounted below the reinforcing frame 7. Rotating sleeves 9 are rotatably connected to both ends of the reinforcing frame 7, and maintenance scrapers 10 are mounted on the rotating sleeves 9. A transmission mechanism 11 is fixedly connected to both ends of the reinforcing frame 7, and a trigger triangle plate 12 is mounted on one side of the transmission mechanism 11. The planetary reducer 4 is a P-series model: this type of reducer typically features high precision and low noise, and is widely used in robotics, automation equipment, and other fields.

[0032] like Figure 2 As shown, two mounting brackets 101 are symmetrically and fixedly connected to the mounting base 1. The mounting brackets 101 are rotatably connected to the bottom of the electric cylinder 6. Each mounting bracket 101 has two clamps that fit over the outer surface of the electric cylinder 6 base. A motor mount 102 is fixedly connected to the mounting base 1, and the motor mount 102 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 in place by the clamps on the support brackets.

[0033] like Figure 2 As shown, the lead screws inside the left and right electric cylinders 6 are left-handed and right-handed lead screws, respectively.

[0034] like Figure 3 As shown, the drive shaft 5 is connected to the reducer inside the electric cylinder 6, and drive wheels 501 are fixedly connected to both ends of the drive shaft 5.

[0035] like Figure 4 As shown, bearings 701 are fixedly connected to both ends of the reinforcing frame 7, and the bearings 701 are fixedly connected to the top of the piston rod of the electric cylinder 6.

[0036] like Figure 5As shown, the following mechanism 8 includes two fixed seats 801. The fixed seats 801 are fixedly connected to the mounting base 1. A turntable 802 is rotatably connected to the middle of the fixed seat 801. The turntable 802 is fixedly connected to the transmission shaft 5. A geared disc 804 is connected to one side of the fixed seat 801. A worm gear 803 is rotatably connected to the geared disc 804. The geared disc 804 is meshed with the transmission wheel 501. A worm wheel 805 is meshed with one side of the worm gear 803. A support rod assembly 806 is fixedly connected to the worm wheel 805. The bottom end of the support rod assembly 806 is rotatably connected to the turntable 802. A hinge seat 807 is rotatably connected to the top end of the support rod assembly 806. The hinge seat 807 is fixedly connected to the reinforcing frame 7. When the drive shaft 5 rotates, it drives the gear plate 804 to rotate through the connected drive wheel 501, which in turn drives the worm 803 to rotate. The worm 803 then drives the strut assembly 806 connected to the worm wheel 805 to rotate, which in turn drives the reinforcing frame 7 to move along with the piston rod of the electric cylinder 6.

[0037] A reinforcing frame 7 is installed on the piston rod of the electric cylinder 6. The reinforcing frame 7 moves with the piston rod under the action of the following mechanism 8, which can effectively assist in supporting the piston rod and reduce its bending deformation; at the same time, it improves motion stability, enhances load-bearing capacity and structural strength. It can significantly improve the working performance, accuracy and reliability of the electric cylinder 6 system, extend the service life of the system, and has significant effects in high-load and high-precision applications.

[0038] like Figure 6 As shown, a sleeve rod 1001 is fixedly connected to one end of the maintenance scraper 10. A sleeve hole 901 is opened on the bottom surface of one side of the rotating sleeve 9. The top end 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 end 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 slidable contact with the piston rod and the top end of the electric cylinder 6. 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.

[0039] like Figure 6 , Figure 7As shown, the transmission mechanism 11 includes a fixed frame 1101. One end of the fixed frame 1101 is fixedly connected to the reinforcing frame 7. A universal joint 1102 is rotatably connected to the fixed frame 1101. A driven wheel 1103 is fixedly connected to one end of the universal joint 1102. A gear ring 902 is fixedly connected to the rotating sleeve 9. The gear ring 902 meshes with the driven wheel 1103 for transmission. A driving wheel 1104 is fixedly connected to the other end of the universal joint 1102. 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, which in turn drives the driven wheel 1103 to rotate. This causes the driven wheel 1103 to drive the rotating sleeve 9 connected to the driven wheel 1103 to rotate.

[0040] like Figure 8 As shown, the inclined surface of the trigger triangle 12 is slidably in contact with the outer wall of the top of the electric cylinder 6. A sliding frame 1201 is fixedly connected to the trigger triangle 12, and a fixed rod 1202 is slidably fitted onto the sliding frame 1201. The fixed rod 1202 is fixedly connected to the reinforcing frame 7, and a tension spring 1203 is fixedly connected to the fixed rod 1202. The other end of the tension spring 1203 is fixedly connected to the sliding frame 1201. A transmission rack 1204 is fixedly connected to one side of the sliding frame 1201, and the transmission rack 1204 meshes with the drive 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 drive the transmission rack 1204 connected to the sliding frame 1201 to move. The tension spring 1203 enables the trigger triangle 12 to automatically reset.

[0041] Working principle: When the load needs to be erected, the servo motor 2 is powered on to drive the planetary reducer 4. The planetary reducer 4 transmits power to the gearbox 3, and the output is transmitted to the two drive shafts 5 through the gear rotation. The drive 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 to complete the lowering action in the same way. The electric cylinder 6, which is connected to the gearbox 3 and the drive shaft 5, is driven by a single servo motor 2, which replaces the traditional two independently controlled transmission systems. While achieving synchronous, reliable and precise control, the overall structure is more streamlined and compact than the traditional two-set control structure. It can meet the installation forms and space requirements of more equipment, achieving multiple benefits in one go.

[0042] At the same time, when the drive shaft 5 rotates, it will drive the gear plate 804 to rotate through the connected drive wheel 501, 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 reinforcing frame 7 to move along the piston rod of the electric cylinder 6.

[0043] Then, when the piston rod of the electric cylinder 6 moves down to reset, when the inclined surface of the trigger triangle plate 12 contacts the electric cylinder 6, it will push the trigger triangle plate 12 to move, causing the trigger triangle plate 12 to drive the transmission rack 1204 connected to the sliding frame 1201 to move, causing the transmission rack 1204 to drive the drive wheel 1104 to rotate. At this time, the drive wheel 1104 will drive the universal joint 1102 to rotate, causing the universal joint 1102 to drive the connected driven wheel 1103 to rotate, causing the driven wheel 1103 to drive the rotating sleeve 9 connected to the driven wheel 1103 to rotate. When the piston rod of the electric cylinder 6 moves up, the trigger triangle plate 12 will not contact the electric cylinder 6. At this time, under the action of the tension spring 1203, the trigger triangle plate 12 will automatically reset, making it convenient for the next use.

[0044] 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.
