Detailed implementation manners

[0024] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0025] Embodiment 1

[0026] Referring to Figures 1-4 , this is the first embodiment of the present utility model, providing a servo hydraulic cylinder. This servo hydraulic cylinder includes a servo hydraulic cylinder main body 1, and also includes a mounting seat 2. A rotating disk 3 is rotatably connected to the mounting seat 2. A plurality of brake blocks 4 are clamped and matched on the outer side of the rotating disk 3. A first connecting seat 5 is fixedly connected to the rotating disk 3. A second connecting seat 6 is hinged to the first connecting seat 5. The second connecting seat 6 is installed and connected to the servo hydraulic cylinder main body 1, and an adjusting mechanism 7 is connected between the first connecting seat 5 and the second connecting seat 6.

[0027] The adjusting mechanism 7 includes a second screw 701 rotatably connected to the first connecting seat 5. Two slide blocks 702 are threadedly connected to the second screw 701. An adjusting plate 704 is slidably connected to the slide blocks 702. The adjusting plate 704 is fixedly connected to the second connecting seat 6.

[0028] In the above technical solution, the rotating disk 3 can rotate 360° on the mounting seat 2, and the second connecting seat 6 can rotate within a certain range on the first connecting seat 5. And the rotation axis of the rotating disk 3 is perpendicular to the rotation axis of the second connecting seat 6. Through the angle adjustment in two dimensions, it can drive the servo hydraulic cylinder main body 1 to be adjusted in multiple directions, improving the installation and use convenience in complex scenarios.

[0029] Among them, after the rotating disk 3 rotates on the mounting base 2, the rotating disk 3 can be rotationally limited by moving the braking block 4 to be clamped with the rotating disk 3. By rotating the second screw 701, the two sliders 702 can be driven to move synchronously. The sliders 702 cooperate with the adjusting plate 704 to drive the second connecting seat 6 to adjust the angle.

[0030] A limiting seat 201 is fixedly connected to the mounting base 2. The rotating disk 3 is rotatably arranged in the limiting seat 201. The braking block 4 is slidably arranged in the limiting seat 201. One side of the braking block 4 is rotatably connected to a first screw 401, and the first screw 401 is in threaded cooperation with the limiting seat 201.

[0031] In the above technical solution, the cross-section of the rotating disk 3 is in a T-shaped structure. The rotating disk 3 is limited in the rotating cavity opened on the limiting seat 201. The rotating disk 3 can rotate 360° around its own center. The braking blocks 4 are distributed at the corners of the limiting seat 201 and are arranged in the sliding cavity opened on the limiting seat 201. By rotating the first screw 401, the braking block 4 can be driven to move. When the braking block 4 moves to abut against the rotating disk 3, the rotation of the rotating disk 3 can be restricted, so that a fixed connection is formed between the rotating disk 3 and the mounting base 2.

[0032] A limiting tooth groove 301 is opened on the edge of the rotating disk 3, and the limiting tooth groove 301 is in clamping cooperation with the braking block 4.

[0033] In the above technical solution, a plurality of protrusions adapted to the limiting tooth groove 301 are provided on the side of the braking block 4 facing the rotating disk 3. When the protrusions are clamped with the limiting tooth groove 301, the rotation of the rotating disk 3 can be restricted.

[0034] An installation plate 601 is fixedly connected to the second connecting seat 6. The servo hydraulic cylinder body 1 is fixedly installed on the installation plate 601.

[0035] In the above technical solution, a through hole is opened on the installation seat 601, which facilitates the piston rod of the servo hydraulic cylinder body 1 to pass through. And an installation hole corresponding to the servo hydraulic cylinder body 1 is opened on the installation seat 601. When the installation hole of the servo hydraulic cylinder body 1 is aligned with the installation hole of the installation seat 601, the installation and fixation are realized through the cooperation of bolts and nuts.

[0036] A slide rail 501 is fixedly connected to the first connecting seat 5. The slider 702 is slidably connected to the slide rail 501.

[0037] In the above technical solution, the number of the slide rails 501 is two, which are arranged in parallel and distributed at both ends of the slider 702. The slide rails 501 limit the sliding direction of the slider 702, so that the slider 702 is driven by the second screw 701 to translate, and the slider 702 drives the second connecting seat 6 to rotate when sliding.

[0038] A fixed rod 703 is fixedly connected to the slider 702, and a sliding hole 705 adapted to the fixed rod 703 is formed in the adjusting plate 704.

[0039] In the above technical solution, when the slider 702 moves, the fixed rod 703 cooperates with the slider 705 to drive the adjusting plate 704 to move. Since the second connecting seat 6 connected to the adjusting plate 704 is hinged to the first connecting seat 5, the second connecting seat 6 can deflect within a certain angle around the hinge axis.

[0040] During use, the mounting seat 2 is fixedly installed with the support structure through the mounting holes, and then the servo hydraulic cylinder main body 1 is fixedly installed with the mounting seat 601. Subsequently, the rotating disk 3 is driven to rotate, and the rotating screw rod two 701 drives the slider 702 to slide. The cooperation between the fixed rod 703 and the sliding hole 705 drives the second connecting seat 6 connected to the adjusting plate 704 to deflect, so as to drive the servo hydraulic cylinder main body 1 to perform azimuth adjustment, so that the piston rod of the servo hydraulic cylinder main body 1 can be connected to the driven object. Subsequently, the rotating screw rod one 401 is rotated to move the brake block 4 to be clamped with the rotating disk 3 to brake the rotation of the rotating disk 3.

[0041] Embodiment 2

[0042] Refer to Figure 2 And Figure 4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that angle scales are provided on both the limit seat 201 and the second connecting seat 6.

[0043] In the above technical solution, indicating arrows are provided at positions corresponding to the angle scales on the rotating disk 3 and the first connecting seat 5, so that when the rotating disk 3 and the second connecting seat 6 rotate, the numerical values of the angle scales can be referred to to achieve precise adjustment, and it is possible to avoid using other tools, improving the installation convenience.

[0044] The remaining structures are the same as those in Embodiment 1.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit.
