[0035] Embodiment 1

[0036] Depend on Figure 1-Figure 4A servo electric cylinder which is easy to fix and install is provided, comprising an electric cylinder 1, a connecting shaft 101 is arranged at the center of the front of the electric cylinder 1, the connecting shaft 101 is fixedly connected to the output shaft of the servo motor in the electric cylinder 1, a power supply port 102 is arranged at the rear end of the top surface of the electric cylinder 1, and an anti-collision pad 104 is arranged on the back of the electric cylinder 1. The anti-collision pad 104 is circular and made of rubber. When the back of the electric cylinder 1 is hit, the anti-collision pad 104 will be hit. Because the anti-collision pad 104 is made of rubber, the secondary force between the molecular structure of the rubber curl makes the rubber material have good shock absorption, sound insulation and buffering properties. Therefore, the rubber anti-collision pad 104 can play a buffering role, reduce the impact force on the electric cylinder 1, thereby reducing the possibility of damage caused by vibration due to excessive impact force on the precision parts in the electric cylinder 1, thereby protecting the electric cylinder 1.

[0037] In order to dissipate heat of the electric cylinder 1, a guide plate 103 is arranged on the electric cylinder 1. The guide plate 103 is wavy. There are ten guide plates 103 divided into two groups, which are symmetrically arranged on the left and right sides of the electric cylinder 1. The air circulation inside the electric cylinder 1 is poor, and heat accumulation is likely to occur after running for a long time. Multiple wavy guide plates 103 can increase the contact area between the electric cylinder 1 and the air, so that natural wind can bring more heat when passing through the electric cylinder 1, reduce the temperature of the outer shell of the electric cylinder 1, and alleviate the heat accumulation of the servo motor in the electric cylinder 1.

[0038] A mounting base 2 is provided below the electric cylinder 1; an adjusting chamber 202 is provided in the mounting base 2, one end of a connecting column 3 is fixedly connected to the bottom surface of the electric cylinder 1, a through hole communicating with the top surface of the adjusting chamber 202 is provided on the top surface of the mounting base 2, the other end of the connecting column 3 passes through the through hole and is arranged in the adjusting chamber 202, a worm gear 301 is provided on the side wall of the other end of the connecting column 3, one end of a worm 302 is rotatably connected to the mounting base 2, the worm 302 is meshed with the worm gear 301, the other end of the worm 302 passes through the side of the adjusting chamber 202 and is arranged on one side of the mounting base 2, and a lever 304 is provided on the other side of the worm 302.

[0039] The staff can install the mounting base 2 at the designated position by means of bolts. After the installation is completed, if it is necessary to adjust the angle of the electric cylinder 1, the worm 302 can be rotated to drive the worm wheel 301 on the side wall of the connecting column 3 to rotate, thereby driving the electric cylinder 1 fixedly connected to the top surface of the connecting column 3 to rotate, thereby adjusting the angle of the electric cylinder 1. The worm 302 is rotated by holding the lever 304. Compared with the smooth outer wall of the worm 302, the lever 304 has a larger holding area and its angular shape makes it easier to apply force during rotation. Moreover, because the worm wheel 301 and the worm 302 are self-locking, the angle of the electric cylinder 1 will not change without human intervention after the adjustment is completed, so that there is no need for the staff to support the electric cylinder 1 all the time, making the installation of the electric cylinder 1 more convenient. In addition, the power supply line is not integrally formed with the electric cylinder 1. After the angle of the electric cylinder 1 is adjusted and the installation is completed, the electric cylinder 1 is connected to the power supply, thereby preventing the power supply line of the electric cylinder 1 from rotating with the electric cylinder 1 during the rotation process.

[0040] Furthermore, the edges and corners of the mounting base 2 are all set to be rounded, and connecting blocks 201 are set at the four corners of the mounting base 2. A long straight slot is opened on the top surface of the connecting block 201. When the staff holds the mounting base 2 to transport the electric cylinder 1, it is not easy to be scratched by the sharp corners, thereby improving safety. The long straight slot allows the installation position of the screw to be adjusted along the opening direction of the long straight slot to adapt to screw holes with different spacings, further facilitating installation.

[0041] Furthermore, in order to facilitate the rotation of the connecting column 3, a fixing block 203 is provided at the center of the bottom surface of the adjusting chamber 202, and a limiting groove 204 is provided in the fixing block 203, and a through hole adapted to the connecting column 3 is provided on the top surface of the limiting groove 204, and the other end of the connecting column 3 is inserted in the limiting groove 204, and a limiting block 303 adapted to the limiting groove 204 is provided on the other end of the connecting column 3, and an annular groove is provided on the bottom surface of the limiting groove 204, and a plurality of balls 205 are provided in the annular groove. The contact between the connecting column 3 and the adjusting chamber 202 is changed to direct contact between the limiting block 303 and the balls 205, and the sliding friction is changed to rolling friction, thereby reducing the friction resistance encountered by the connecting column 3 during rotation, thereby making it more convenient for the staff to apply force to adjust the angle of the electric cylinder 1 by rotating the worm 302.

[0042] Embodiment 2

[0043] Based on the first embodiment, specifically, Figure 5As shown, a slider 305 is also directly provided between the worm 302 and the lever 304, a sleeve 306 is slidably connected to the slider 305, a friction groove 307 is provided on the mounting seat 2, a friction block 308 is provided between the sleeve 306 and the lever 304, a rotating block 309 is rotatably connected in the friction groove 307, the rotating block 309 is fixedly connected to the worm 302, and a spring is provided between the rotating block 309 and the friction block 308.

[0044] In the utility model, by adopting the above-mentioned design, under normal conditions, the spring arranged between the friction block 308 and the rotating block 309 will keep the friction block 308 in close contact with the friction groove 307 at all times. The large friction force therebetween will prevent the worm 302 from rotating, and the vibration generated during the operation of the device will not cause the angle of the electric cylinder 1 to rotate, thereby making the operation of the device more stable.

[0045] Working principle:

[0046] To facilitate installation and fixation and angle adjustment after installation.

[0047] In the utility model, a connecting block 201 , a connecting column 3 , a worm wheel 301 and a worm 302 are provided.

[0048] Therefore, after the staff installs the mounting base 2 at the designated position by means of bolts, if the angle of the electric cylinder 1 needs to be adjusted, the staff can rotate the worm 302 to drive the worm wheel 301 on the side wall of the connecting column 3 to rotate, thereby driving the electric cylinder 1 fixedly connected to the top surface of the connecting column 3 to rotate, and adjusting the angle of the electric cylinder 1. Moreover, because the worm wheel 301 and the worm 302 are self-locking, the angle of the electric cylinder 1 will not change without human intervention after the adjustment is completed, so that there is no need for the staff to support the electric cylinder 1 at all times, making the installation of the electric cylinder 1 more convenient. Moreover, the installation position of the screw can be adjusted on the connecting block 201 along the direction of the long straight slot thereon to adapt to screw holes with different spacings, which further facilitates the installation of the device and improves the versatility of the device.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
