[0002] In modern industrial automation production lines, servo cylinders, as important actuators, are widely used in various precision machining, assembly, and testing processes. In equipment like seal test benches, servo cylinders play a particularly critical role, as they directly impact the accuracy of test results and the reliability of the equipment.

[0003] Traditional servo cylinders are typically installed by placing them directly on a mounting base and securing them in place with bolts. However, before bolting, to ensure the correct positioning of the servo cylinder, repeated adjustments are required to precisely align the holes in the cylinder base with those in the mounting base. During this process, sliding friction between the cylinder base and the mounting base not only increases the difficulty of adjustment but can also damage the mounting base surface, affecting the overall levelness and stability of the equipment.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "embodiment" as used herein refers to specific features, structures, or characteristics that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example

[0038] Reference Figure 1-Figure 2This embodiment provides a servo electric cylinder fixing device for a sealing test bench, including a base 1 on which the servo electric cylinder is fixed, and a screw hole is opened on the base 1; and further comprising:

[0039] The fixing seat 2 is used to fix the base 1 and includes a top plate 21, side plates 22 and a bottom plate 23. The top plate 21 is provided with bolt holes that cooperate with the bolt holes on the base 1 to fix the base 1 to the top plate 21; the side plates 22 connect the top plate 21 and the bottom plate 23, and leave a certain space between the top plate 21 and the bottom plate 23. To improve strength, the side plates 22 are two pieces, and the top plate 21, side plates 22 and bottom plate 23 are connected by welding; the top plate 21 is provided with at least one through hole. If the servo cylinder is long, the number of through holes can be adjusted according to the length of the servo cylinder to provide stable support for the base 1;

[0040] The lifting seat 3 slides vertically at the through hole. A plurality of balls 4 are rotatably mounted on the lifting seat 3. The balls 4 are distributed in a matrix pattern on the lifting seat 3. The matrix-shaped distribution of the balls 4 can more evenly distribute the load, thereby improving the load-bearing capacity of the lifting seat 3.

[0041] The driving mechanism 5 is installed between the lifting seat 3 and the bottom plate 23, and is used to drive the lifting seat 3 to slide;

[0042] When the base 1 is adjusted, the lifting seat 3 rises, so that the ball 4 is higher than the top surface of the top plate 21;

[0043] After the adjustment is completed, the lifting seat 3 is lowered so that the ball 4 is lower than the top surface of the top plate 21;

[0044] The working principle of this device is as follows: when the position of the servo electric cylinder needs to be adjusted, the driving mechanism 5 drives the lifting seat 3 to rise so that the ball 4 is higher than the top surface of the top plate 21. At this time, the ball 4 acts as a rolling support between the base 1 and the top plate 21, thereby greatly reducing the friction between the base 1 and the top plate 21. The base 1 can slide easily on the top plate 21, and the operator can conveniently adjust the position of the servo electric cylinder until the bolt holes on the base 1 are aligned with the bolt holes on the fixed seat 2. After the position adjustment is completed, the driving mechanism 5 causes the lifting seat 3 to descend, and the ball 4 retreats to a position lower than the top surface of the top plate 21. At this time, the base 1 directly contacts the top plate 21, and is then fixed by bolts passing through the corresponding bolt holes on the top plate 21 and the base 1. At this time, the base 1 is firmly mounted on the fixed seat 2.

[0045] In the traditional installation process, the power mechanism 52 is usually installed longitudinally, which increases the space occupied by the equipment. Figure 3 and Figure 4 , the utility model proposes an optimized driving mechanism solution, the driving mechanism 5 includes a connecting plate 51, a power mechanism 52, a pushing frame 53 and a pushing shaft 54;

[0046] The connecting plate 51 is fixed to the bottom of the lifting seat 3 and is located in the middle of the bottom of the lifting seat 3 to prevent the lifting seat 3 from shifting when loaded. The connecting plate 51 is provided with a guide hole including an inclined section 55.

[0047] The power mechanism 52 is fixed to the top of the base plate 23. The power mechanism 52 is fixed by bolts or the like. The power mechanism 52 can be a pneumatic cylinder, an oil cylinder, or an electric telescopic rod. The purpose is to drive the push frame 53 to move in a straight line. The power mechanism 52 is fixed horizontally on the base plate 23, which can also reduce the space occupied.

[0048] The push frame 53 is fixed to the output end of the power mechanism 52, and the push frame 53 can slide horizontally under the action of the power mechanism 52;

[0049] The driving shaft 54 is fixedly connected to the driving frame 53 and passes through the inclined section 55. In order to reduce the wear on the driving shaft 54, a bearing is fixed on the driving shaft 54, and the outer ring of the bearing is tangent to the inner wall of the guide hole;

[0050] There is an angle between the sliding trajectory of the driving shaft 54 and the inclined section 55;

[0051] The working principle of the driving mechanism 5 is as follows: when the position of the servo cylinder needs to be adjusted, the power mechanism 52 is started, and the pushing frame 53 and the pushing shaft 54 move horizontally. Because there is a certain angle between the sliding trajectory of the pushing shaft 54 and the inclined section 55 of the guide hole, the horizontal movement of the pushing shaft 54 will be converted into a vertical upward movement of the lifting seat 3, so that the ball 4 is higher than the top surface of the top plate 21. At this time, the base 1 can be easily adjusted. After the adjustment is completed, the power mechanism 52 operates in the reverse direction, the pushing shaft 54 retracts, the lifting seat 3 drops accordingly, and the ball 4 is lower than the top surface of the top plate 21. At this time, the base 1 can be fixed to the top plate 21 by bolts.

[0052] In the traditional servo cylinder installation process, since the guide hole only includes the inclined section 55, the power mechanism 52 needs to have a relatively precise stroke, which increases the cost of the power mechanism 52. Figure 4 The present invention proposes an optimized driving mechanism solution. The guide hole also includes a horizontal section 56. One end of the horizontal section 56 is connected to one end of the inclined section 55. When the lifting seat 3 moves upward, the driving shaft 54 first passes through the inclined section 55 and then passes through the horizontal section 56. The sliding trajectory of the driving shaft 54 is parallel to the horizontal section 56. Since the sliding trajectory of the driving shaft 54 is parallel to the horizontal section 56, when the driving shaft 54 moves in the horizontal section 56, the driving shaft 54 will not affect the height of the lifting seat 3 when moving in the horizontal section 56, thereby effectively reducing the requirements for the stroke of the power mechanism 52.

[0053] In the traditional installation process, the single-sided support design of the push shaft 54 easily causes the push shaft 54 to deflect during the movement, resulting in a break between the push shaft 54 and the push frame 53, affecting the adjustment accuracy and the stability of the system; In order to solve these problems, refer to Figure 4 The present invention proposes an optimized driving mechanism solution. The pushing frame 53 is door-shaped, and the two ends of the pushing frame 53 are respectively located on both sides of the connecting plate 51; the driving mechanism 5 also includes a track 57 fixed on the bottom plate 23, and the pushing frame 53 is slidably connected to the track 57, so that the pushing shaft 54 can be supported on both sides, effectively improving the smoothness and accuracy of the movement of the pushing shaft 54, and enhancing the overall stability and reliability of the system.

[0054] This utility model proposes an optimized driving mechanism scheme, referring to Figure 3 The top surface of the bottom plate 23 is fixedly connected to a support 6, and the bottom of the lifting seat 3 is fixedly connected to a sliding rod 7 that is slidably connected to the support 6. The support 6 is door-shaped, and both ends of the support 6 are connected to the top surface of the bottom plate 23. A through hole is also opened in the middle of the support 6 for the connecting plate 51 to pass through to prevent affecting the movement of the connecting plate 51.

[0055] In the traditional servo cylinder installation process, the lifting seat 3 may have poor stability during adjustment and fixation due to insufficient support points, especially when the load is large, it is easy to tilt or offset, affecting the adjustment accuracy and reliability of the equipment; Figure 3 The utility model proposes an optimized driving mechanism solution. The sliding rods 7 are distributed at the four corners of the bottom of the lifting seat 3, ensuring uniform support of the lifting seat 3 in all directions, improving the stability of the lifting seat 3 during adjustment and fixing, thereby enhancing the overall accuracy and reliability of the system.

[0056] In the traditional installation process of the servo electric cylinder, the installation method of the ball 4 is relatively complicated, which makes it inconvenient to replace the ball 4. The utility model proposes an optimized driving mechanism solution. The lifting seat 3 includes a flat plate 31 and a cover plate 32; the top surface of the flat plate 31 is provided with a plurality of grooves for placing the ball 4; the cover plate 32 is fixed to the top of the flat plate 31, and the cover plate 32 is provided with notches corresponding to the ball 4 one by one, and the inner wall of the notch is arc-shaped, so that the cover plate 32 can cover the ball 4; the top end of the ball 4 protrudes from the cover plate 32, which not only ensures the precise positioning and stable support of the ball 4, but also improves the smoothness of the adjustment of the base 1 and the reliability of the entire system.

[0057] In the traditional servo cylinder installation process, the base 1 may exceed the predetermined range when adjusting the position, resulting in position deviation or inaccurate fixation; in order to solve these problems, refer to Figure 1-Figure 2The utility model proposes an optimized driving mechanism solution. The top plate 21 is provided with multiple limit members 8, and the multiple limit members 8 are distributed circumferentially on the base 1. The limit members 8 can be bolts, limit blocks, limit pins, magnetic limiters, etc., which can effectively limit the movement range of the base 1 and ensure that the base 1 will not deviate from the predetermined area when adjusting the position, thereby improving the adjustment accuracy and the reliability of the entire system.

[0058] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.

[0059] 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 the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
