Description

Technical Field

[0001] This utility model relates to the field of servo multistage electric cylinders, and in particular to a servo multistage electric cylinder. Background Technology

[0002] Servo multistage electric cylinders are typically derived from single-stage electric cylinders and are mainly used to meet the working requirements of long stroke and high load.

[0003] Existing servo multistage electric cylinders typically include a servo motor, multiple cylinder bodies, telescopic components, a base, and a mounting bracket. The telescopic components are placed inside the cylinder bodies, and the servo motor and cylinder bodies are mounted on the base. When using a servo multistage electric cylinder, the mounting bracket is usually connected to a designated position, and then multiple bolts are used to lock and fix the mounting bracket to the designated position to install and fix the servo multistage electric cylinder.

[0004] When it is necessary to remove and maintain a servo multistage electric cylinder, it is usually necessary to use a special disassembly tool and then unscrew multiple bolts one by one to separate the mounting base from the designated position, thus enabling the removal and maintenance of the servo multistage electric cylinder. However, this method is subject to operational dependence, which affects the efficiency of disassembly. Therefore, it is necessary to enable the servo multistage electric cylinder to be quickly separated from the designated position to improve maintenance efficiency. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] This utility model provides, for example Figure 1-3 The image shows a servo multistage electric cylinder.

[0037] Example 1

[0038] The system includes a base 1 on the side of which a servo motor 2 and a cylinder 3 are mounted, and the base 1 provides support for the cylinder 3 and the servo motor 2; a first seat 4 and a second seat 5 are respectively mounted on the two ends of the cylinder 3, and the first seat 4 and the second seat 5 provide support for the cylinder 3; a connecting mechanism 6 is provided on the first seat 4 and the second seat 5, and the connecting mechanism 6 is used to make the first seat 4 and the second seat 5 uniformly separate from the designated position.

[0039] Furthermore, the connecting mechanism 6 includes an assembly plate 61, a fixing post 62, an insert plate 63, and a locking element. The assembly plate 61 facilitates installation at a designated position via bolts. The assembly plate 61 also supports the insert plate 63, facilitating connection between the first seat 4 and the second seat 5 for the installation and positioning of the cylinder 3. The fixing post 62 provides sliding support for the positioning post 64. The insert plate 63 facilitates connection with the first seat 4 and the second seat 5 for the installation and positioning of the cylinder 3. Adjacent assembly plates 61 are located on the sides of the first seat 4 and the second seat 5. Adjacent fixing posts 62 are fixedly connected to the sides of the first seat 4 and the second seat 5. The insert plate 63 is fixedly connected to the sides of the assembly plate 61. Adjacent insert plates 63 are located on the first seat 4 and the second seat 5, respectively. The locking element is located on the fixing post 62.

[0040] Specifically, the connecting mechanism 6 also includes an installation groove, a first through groove, a sliding groove, and a movable plate 69. The movable plate 69 facilitates the connection of two traction plates 68 in series, thereby facilitating the simultaneous movement of the two traction plates 68 to operate multiple positioning posts 64 simultaneously. The installation groove is located on the side of the first base 4 and the second base 5. The insert plate 63 is slidably inserted into the inner cavity of the installation groove. The first through groove is located on the side of the fixed post 62. The sliding groove is located on the side of the inner wall of the installation groove.

[0041] Specifically, the locking components include positioning pins 64, auxiliary frames 65, traction rods 66, and traction plates 68. Multiple positioning pins 64 are present. These pins help to define the relative positions of the insertion plate 63 and the first or second seat 4, thereby facilitating the installation and removal of the cylinder 3, enabling quick disassembly and improving disassembly efficiency. The auxiliary frame 65 supports the compression of the spring 67 and the sliding of the traction rod 66. The traction rod 66 pulls the positioning pins 64 to separate them from the insertion plate 63 and guides the deformation of the spring 67. The traction plate 68... 8 is conducive to simultaneously driving multiple traction rods 66 in the same row to move, thereby simultaneously driving multiple positioning posts 64 in the same row to slide horizontally. The positioning posts 64 are slidably inserted into the inner cavities of the first through groove and the slide groove. The auxiliary frame 65 is slidably inserted into the inner cavity of the first through groove. The end of the traction rod 66 is fixedly connected to the positioning post 64. The traction rod 66 is slidably inserted into the inner cavity of the auxiliary frame 65. The side of the traction plate 68 is threadedly connected with a positioning bolt, which is conducive to connecting the traction plate 68 and the traction rod 66, and thus facilitates the installation and disassembly of the traction plate 68. One end of the positioning bolt is threadedly inserted into the traction rod 66. The top of the traction plate 68 is fixedly connected to the moving plate 69.

[0042] Example 2

[0043] Based on Embodiment 1, the locking component also includes a spring 67 and a limiting groove. The elastic force of the spring 67 facilitates the movement of the positioning post 64, making it easy for the positioning post 64 to return to its original position after movement, and facilitating repeated operation of the positioning post 64. The spring 67 is sleeved on the outside of the traction rod 66. One end of the spring 67 is in contact with the auxiliary frame 65, and the other end of the spring 67 is in contact with the positioning post 64. The limiting groove is opened on the side of the through plate 63. The positioning post 64 is slidably inserted into the inner cavity of the limiting groove. The side of the fixing post 62 is threaded with a mounting bolt 610, which facilitates the installation and disassembly of the auxiliary frame 65 to remove the positioning post 64 and the spring 67. One end of the mounting bolt 610 is threadedly inserted into the auxiliary frame 65.
