Description

Technical Field

[0001] The utility model relates to the technical field of electric cylinder module equipment, in particular to an electric cylinder module. Background Art

[0002] The electric cylinder module, also known as the driven slide, is a type of linear motor. Its structure uses a rotating screw to drive the slide to move horizontally.

The ball screw 11 is rotatably connected to the rear end plate 5, and a linear bearing 8 is provided at the position corresponding to the ball screw 11 in the front end plate 2. A slide seat 6 is provided on the ball screw 11, and a connecting sleeve 10 is provided at the front end of the slide seat 6. A telescopic rod 14 is detachably connected to the connecting sleeve 10, and the telescopic rod 14 is fitted with the linear bearing 8. The telescopic rod 14 is hollow and has an inner diameter larger than the outer diameter of the ball screw 11. A slide rail 12 is provided in the shell 1, and the slide rail 12 is located on both sides of the ball screw 11, and the slide rail 12 is fitted with the bottom end of the slide seat 6;

[0024] In the present invention, a ball screw 11 and a connecting sleeve 10 are provided. The ball screw 11 can rotate under the drive of the driving component 3 and use its own rotation to drive the slide 6 to move. The ball screw 11 has the advantages of high precision, high life and high load. In addition, the connecting sleeve 10 can be used to connect the telescopic rod 14 to the side of the slide 6, so that the telescopic rod 14 is driven to move when the slide 6 moves. The telescopic rod 14 is set in a hollow manner so that it will not be interfered with by the ball screw 11, and the telescopic rod 14 is concentric and coaxial with the ball screw 11, which can evenly apply force to the ball screw 11, thereby achieving the purpose of high-load push-pull or press-fit movement.

[0025] An oil groove 13 is provided on the slide rail 12, and lubricating oil can be accumulated in the oil groove 13;

[0026] By providing the oil groove 13 , lubricating oil can be stored in the oil groove 13 . When the slide 6 moves, the lubricating oil can reduce the friction between the slide 6 and the slide rail 12 , so that the movement of the slide 6 is smoother.

[0027] A detachable sliding pad 15 is provided under the slide 6, and the sliding pad 15 is slidably connected to the slide rail 12;

[0028] By providing the sliding pad 15 , the sliding pad 15 can separate the slide seat 6 from the slide rail 12 and then directly contact the slide rail 12 . This approach can avoid wear of the slide seat 6 , and the sliding pad 15 can be quickly replaced by utilizing the detachable connection with the slide seat 6 .

[0029] A telescopic cover plate 7 is provided between the front end plate 2 and the rear end plate 5. The telescopic cover plate 7 is slidably connected to the inside of the housing 1 and is fixedly connected to the slide seat 6.

[0030] By setting up the telescopic cover 7, the opening above the shell 1 can be closed by using the telescopic cover 7 to prevent foreign objects from entering the module, thereby ensuring the stable and safe operation of the ball screw 11. In addition, the telescopic cover 7 can be telescoped along with the slide 6 when it moves, so that it will not run the movement process of the slide 6.

[0031] The front end of the ball screw 11 is provided with a rotating bearing 9, which is detachably connected to the linear bearing 8;

[0032] By setting up the rotating bearing 9, when the telescopic rod 14 is disassembled, the rotating bearing 9 can be placed in the linear bearing 8, and the front end of the ball screw 11 can be supported by the rotating bearing 9 to ensure that the ball screw 11 can still rotate stably without the support of the telescopic rod 14 and the linear bearing 8.

[0033] The driving component 3 includes a motor 301, a driving pulley 302, a driven pulley 304 and a transmission belt 303. The motor 301 is arranged on the side of the rear end plate 5 and passes through it. The driving pulley 302 is connected to the motor 301, the driven pulley 304 is connected to the ball screw 11, and the transmission belt 303 is connected between the driving pulley 302 and the driven pulley 304.

[0034] By setting up a transmission belt 303 and connecting the driving pulley 302 and the driven pulley 304 with the transmission belt 303, the transmission position of the driving force can be changed, the length of the module equipment can be shortened, and the transmission belt 303 will slip after being overloaded, which can avoid overload damage to the motor 301.

[0035] A protective cover 4 is provided on the outside of the rear end plate 5, and the driving pulley 302, the driven pulley 304 and the driven belt are all located inside the protective cover 4;

[0036] By providing the protective cover 4 , the transmission belt 303 can be protected by the protective cover 4 , which can prevent noise from being transmitted on the one hand, and prevent foreign matter from interfering with the normal operation of the transmission belt 303 on the other hand.

[0037] Working principle:

[0038] During movement, the motor 301 drives the active pulley 302 to rotate, and the active pulley 302 drives the driven pulley 304 to rotate via the transmission belt 303, and the driven pulley 304 drives the ball screw 11 to rotate, and the ball screw 11 drives the slide 6 to move linearly, and the slide 6 moves horizontally under the restriction of the slide rail 12. When the module is required to push, pull or press-fit, the telescopic rod 14 is connected to the connecting sleeve 10 through the linear bearing 8. At this time, the movement of the slide 6 will drive the telescopic rod 14 to move through the connecting sleeve 10. The telescopic rod 14 uses an internal hollow design to prevent it from being interfered with by the ball screw 11, and the telescopic rod 14 uses a concentric and coaxial setting with the ball screw 11 to give it a higher load capacity.

[0039] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
