Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder pulse testing, in particular to a cylinder body fixing device for servo pulse testing. Background Art

[0002] In modern industrial production and equipment testing, hydraulic cylinders, as key components, typically undergo a series of rigorous performance tests before use. Servo pulse testing is a key method for evaluating a cylinder's dynamic performance. It simulates pulse pressure changes under actual operating conditions to verify the cylinder's durability and stability.

[0003] During servo pulse testing, the cylinder must be effectively secured to ensure stability and data accuracy. Currently, the industry's most common approach is to place support blocks beneath the cylinder to maintain stability. These support blocks typically feature a curved top that matches the cylinder's outer surface, ensuring the cylinder rests securely on top without causing unnecessary vibration or displacement due to poor contact.

[0004] However, existing support block designs have a significant drawback: the spacing between them is often fixed or difficult to adjust. This design is inflexible when dealing with cylinders of varying sizes or lengths, increasing test preparation time and costs. In some cases, it may not provide sufficient support stability, affecting the accuracy and reliability of test results. Utility Model Content

[0012] a driving mechanism, disposed on the base plate, for driving the driving rod to rotate, so that when the driving rod rotates, the distance between the base plate and the adjustment plate, and between adjacent adjustment plates, changes;

[0013] Wherein, the support block is installed on the base plate and each of the adjustment plates.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0030] 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.

[0031] 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. Example

[0032] Reference Figure 1-Figure 3 This embodiment provides a cylinder fixing device for servo pulse testing, comprising a plurality of support blocks 1, wherein the top surface of the support blocks 1 is arc-shaped and closely adheres to the outer wall of the cylinder to be tested; and further comprising:

[0033] There are two guide rails 2, which are arranged in parallel. When in use, the guide rails 2 are fixed to the external support surface;

[0034] Base plate 3, fixed on one end of guide rail 2;

[0035] An adjusting plate 4, at least one, capable of sliding along the length direction of the guide rail 2;

[0036] A driving rod 5, wherein the middle section of the driving rod 5 is rotatably connected to the base plate 3;

[0037] There is at least one swinging rod 6, each swinging rod 6 is hinged to the center of a corresponding adjustment plate 4; one end of the swinging rod 6 closest to the driving rod 5 is hinged to the driving rod 5; each swinging rod 6 has only one end rotatably connected to one end of the adjacent swinging rod 6; two adjacent swinging rods 6 form a V-shaped structure;

[0038] The driving mechanism 7 is provided on the base plate 3 and is used to drive the driving rod 5 to rotate. When the driving rod 5 rotates, the distance between the base plate 3 and the adjustment plate 4, as well as between adjacent adjustment plates 4, changes.

[0039] Among them, a support block 1 is installed on the base plate 3 and each adjustment plate 4;

[0040] The working principle of the present invention is as follows: when the cylinder to be tested is being tested, the support block 1 is arranged along the axis direction of the cylinder, and the outer wall of the cylinder is in close contact with the arc-shaped top surface of the support block 1, which plays a role in supporting the cylinder. When the length of the cylinder to be tested changes, the driving mechanism 7 is started and the driving rod 5 will rotate accordingly. Since the end of the swing rod 6 closest to the driving rod 5 is hinged to the driving rod 5, each swing rod 6 has only one end that is rotatably connected to one end of the adjacent swing rod 6, and the two adjacent swing rods 6 form a V-shaped structure. Therefore, when the driving rod 5 rotates, the angle between the driving rod 5 and its adjacent swing rod 6 and the angle between the adjacent swing rods 6 will change, thereby driving the base plate 3 and the adjustment plate 4, as well as the spacing between the adjacent adjustment plates 4 to change. The position of the support block 1 of this device can be easily adjusted by the driving mechanism 7, so it can quickly adapt to cylinders of different sizes, reducing the preparation time when replacing the test piece and improving work efficiency.

[0041] In order to further improve the adjustment accuracy and operation convenience of the cylinder fixing device for servo pulse testing, as a preferred solution of the present invention, referring to Figure 2 , the driving mechanism 7 includes a power mechanism, which can be an air cylinder, an oil cylinder or an electric telescopic rod;

[0042] One end of the power mechanism is rotatably connected to the base plate 3, and the other end of the power mechanism is rotatably connected to the other end of the driving rod 5;

[0043] The working principle of the driving mechanism 7 is as follows: when the power mechanism is started, the driving rod 5 rotates around its center, and the rotational motion of the driving rod 5 is transmitted to the adjustment plate 4 through the swing rod 6, thereby driving the adjustment plate 4 to slide on the guide rail 2. As the position of the adjustment plate 4 changes, the support block 1 installed on it also moves accordingly, greatly improving the test efficiency.

[0044] In order to increase the overall structural stability of the driving rod 5, as a preferred solution of the present invention, Figure 2 As shown, the driving rod 5 is in an obtuse angle shape and is fixedly connected to a reinforcing rod 8. The reinforcing rod 8 connects the two ends of the driving rod 5 to form a triangular structure. The triangular structure has extremely high stability due to its geometric characteristics and can effectively resist deformation under the action of external forces, ensuring that the structure of the driving rod 5 remains unchanged during the servo pulse test, thereby improving the stability of the test.

[0045] In order to further improve the stability and sliding smoothness of the adjustment plate 4, as a preferred solution of the present invention, refer to Figure 3 , a track 9 is provided on the guide rail 2;

[0046] Both sides of the base plate 3 are rotatably connected with rollers 10 that roll along the track 9. This design not only ensures the stability of the adjustment plate 4 during movement, but also effectively reduces friction resistance, making the operation of the entire device smoother and more reliable.

[0047] In order to prevent foreign objects from falling onto the track 9 and causing the roller 10 to get stuck, as a preferred solution of the present invention, the guide rail 2 is fixedly connected to a protective cover 11, and the top of the protective cover 11 is bent to form a protective cover 12 on the roller 10. This not only prevents external impurities from entering between the guide rail 2 and the roller 10, reducing the risk of wear and jamming, but also improves safety during operation and prevents injuries caused by accidental touch, thereby ensuring long-term and stable operation of the device.

[0048] In order to further improve the maintenance convenience of the track 9 and the roller 10, as a preferred solution of the present invention, refer to Figure 1 The protective cover 11 is detachably connected to the guide rail 2. The detachable connection forms include threaded connection, snap connection, magnetic connection, pin connection and hinge connection. When maintenance or replacement of parts is required, the protective cover 11 can be quickly removed to simplify the operation process and improve work efficiency.

[0049] In the conventional servo pulse test cylinder fixing device, the support block 1 is usually mounted on the base plate 3 and the adjustment plate 4 by fixing screws or other more complicated methods. Although such a design is stable, it is often time-consuming and laborious to replace the support block 1. As a preferred solution of the present invention, referring to Figure 1 , the base plate 3 and the top of the adjustment plate 4 are fixed with a fixing block 13, and the fixing block 13 has a slot;

[0050] The bottom of the support block 1 is fixedly connected to a connecting block 14 that extends into the slot. This design not only makes the installation and removal of the support block 1 simpler and faster, but also facilitates the rapid replacement of different types of support blocks 1 according to different testing requirements, thereby enhancing the adaptability and operational efficiency of the device.

[0051] In order to further improve the stability and reliability of the support block 1, as a preferred solution of the present invention, refer to Figure 1 A locking piece 15 for fixing the position of the connecting block 14 is provided on the fixing block 13. The locking piece 15 adopts a threaded handle, which generates pressure on the connecting block 14 by rotation to fix the connecting block 14. It can not only ensure that the position of the support block 1 is stable after installation and avoid displacement caused by vibration or other external forces during the test, but also when the support block 1 needs to be replaced, the locking piece 15 can be unlocked through simple operation to quickly complete the disassembly and assembly.

[0052] 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.

[0053] 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.
