[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that while the description of these embodiments is intended to aid understanding of the present invention, they do not constitute limitations on the present invention. The specific structural and functional details disclosed herein are merely intended to illustrate exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms, and should not be construed as being limited to the embodiments described herein.

[0025] According to the first aspect of the present invention, a cement compression clamp is provided. Figure 1 and Figure 2 One specific embodiment is shown.

[0026] See Figure 1 and Figure 2 As shown, the cement compression-resistant clamp includes: an anti-compression seat 1, which has a basic height and an open mouth on the anti-compression seat 1; a lower pressure plate, which is arranged on the anti-compression seat 1 and is used to carry the sample block; an upper pressure plate, which is connected to the movable end of the driving device 5; and a chuck 4, which is sleeved on the outer periphery of the upper pressure plate, and the chuck 4 is connected to the fixed end of the driving device 5; wherein, the upper pressure plate is movably connected to the anti-compression seat 1 through a guide structure, and when the driving device 5 moves, the upper pressure plate can only move in the vertical direction and act on the cement test block on the lower pressure plate.

[0027] With the above-described technical solution, the cement test block is placed on the lower platen, while the upper platen is connected to the movable end of the drive device 5 and moves vertically under the action of the drive device 5. The upper platen moves downward until it contacts the cement test block and continuously applies pressure until the test block fails. During the downward movement of the upper platen, the guide structure ensures that the upper platen can only move vertically, preventing the upper platen from moving the cement test block when applying force, thereby ensuring the accuracy of the overall test results.

[0028] In the present disclosure, a screw drive mechanism is used to drive the upper pressure block to move up and down. Specifically, a screw hole is provided in the upper pressure block and is sleeved on the outer circumference of the screw. When the screw rotates, the rotational motion is converted into linear motion, thereby driving the upper pressure block to move and complete the pressure test.

[0029] In an embodiment provided in the present disclosure, the guide structure includes a guide hole 61 and a guide column 62. The guide hole 61 is formed on the anti-pressure seat 1 and extends in the vertical direction; the guide column 62 is fixedly connected to the upper pressure plate, and the guide column 62 is partially embedded in the guide hole 61.

[0030] A guide hole 61 is formed in the anti-pressure seat 1 and extends vertically, providing a stable movement path for the upper pressure plate, ensuring that it does not deviate from the vertical direction during force application. A guide post 62 is fixedly connected to the upper pressure plate and partially embedded in the guide hole 61. The cooperation between the guide post 62 and the guide hole 61 restricts the movement of the upper pressure plate, restricting it to movement in the direction of the guide hole 61 (i.e., the vertical direction).

[0031] The guide structure ensures that the upper platen does not move the cement test block when force is applied, thus avoiding deviations in test results caused by test block movement. The guide structure makes the movement of the upper platen more stable, reducing shaking and instability during the test process, and ensuring the accuracy of the test results.

[0032] Furthermore, the longitudinal cross-section of the guide post 62 is circular. This circular shape reduces the contact surface between the guide post 62 and the guide hole 61, and evenly distributes contact pressure, helping to reduce friction and wear and extend service life. Furthermore, by reducing friction between the guide post 62 and the guide hole 61, the upper platen moves more smoothly.

[0033] The cement compression fixture also includes a guide block 71 with a through-hole. A boss is formed on the lower pressure plate, with guide pins 72 on either side of the boss that mate with the through-hole. The guide block 71 fits within the guide pins 72. The guide block 71 mates with the guide pins 72 on either side of the boss on the lower pressure plate, allowing it to fit stably within the guide pins 72. This ensures that the cement test block is accurately aligned with the center position when placed in the fixture, preventing the test block from tilting or shifting, and ensuring the accuracy and reliability of the test results.

[0034] In the present disclosure, the upper platen has a non-circular cross-section, and the inner hole of the chuck 4 is formed to match the upper platen's shape, allowing the upper platen to move only vertically within the chuck 4. This arrangement ensures the stability and accuracy of the upper platen during movement, avoids unnecessary deflection or rotation during movement or force application, and thus improves the reliability and performance of the overall structure.

[0035] Specifically, the side wall of the upper pressing plate is provided with at least one plane, and the inner hole of the chuck 4 is formed with a matching surface corresponding to the plane. The provision of at least one plane can make the upper pressing plate have a stable positioning effect in the chuck 4, and through the matching of the plane and the matching surface, the chuck 4 further plays a limiting and guiding role on the upper pressing plate, ensuring the stability and accuracy of the upper pressing plate in the chuck 4.

[0036] In this way, based on the cooperation between the plane of the side wall of the upper pressing plate and the matching surface of the inner hole of the chuck 4, the upper pressing plate can stably move in the vertical direction in the chuck 4, avoiding unnecessary deviation or rotation during movement or force application, improving the reliability and use effect of the overall structure, and ensuring the accuracy and stability of the clamp during work

[0037] In an embodiment provided in the present disclosure, the chuck 4 is connected to the driving device 5 through the support 8. Specifically, the support 8 is connected to the driving device 5 through a detachable connection structure of bolts and nuts, so as to facilitate disassembly and maintenance, and has good flexibility and practicality.

[0038] In the present disclosure, the two sides of the support 8 are respectively provided with lugs, and the lugs are provided with push blocks 91 and fixing plates 92. The lugs are provided with push blocks 91, which can be used to transmit force or realize certain mechanical actions. The lugs are also provided with fixing plates 92, which are usually used to connect and fix other components to enhance the stability of the structure. The support 91 is mainly used to adjust the fixed distance on the compression device, and the support 91 is provided with rollers to realize the up-down movement of the clamp, so as to make the compression data accurate. The support 92 is mainly used to fix the push block 91, and when the position of the push block 91 is fixed, the support 92 is used for fixation, so as to achieve the overall stability.

[0039] The support 8 is also provided with a fixing block 93, which is used to fix the position and direction of the clamp when the compression clamp is replaced, so as to improve the installation efficiency.

[0040] Finally, it should be pointed out that the present application is not limited to the above-mentioned optional embodiments, and anyone can derive other various forms of products under the inspiration of the present application. The above specific embodiments should not be understood as limiting the protection scope of the present application, and the protection scope of the present application should be defined by the claims, and the specification can be used to interpret the claims.
