Description

Technical Field

[0001] This invention relates to the field of clamping technology, and more particularly to a disc spring clamp. Background Technology

[0002] In disc spring performance testing, the high-temperature creep test is an important test item, which can reflect the deformation characteristics of disc springs under long-term stress in a high-temperature environment. In this test, the disc spring needs to be clamped and fixed with a certain preload and maintained in this state for a long time under high temperature conditions. Therefore, the structural stability and ease of operation of the clamping device directly affect the experimental efficiency and the reliability of the results.

[0003] Existing disc spring clamping devices typically employ bolt fastening, where tightening the bolts moves the pressure plate downwards and clamps the disc spring. These devices present several problems in practical use: bolt fastening requires multiple parts such as nuts and washers, resulting in a complex structure; each adjustment of the pressure plate height to accommodate different numbers or thicknesses of disc springs necessitates loosening or tightening the bolts, making operation cumbersome; and during prolonged high-temperature creep experiments, the bolt connections are prone to loosening due to factors such as material thermal expansion and contraction, altering the stress state of the disc spring and affecting the accuracy of the experimental results. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, the present invention proposes a disc spring clamp that can provide stable clamping of disc springs and is easy to operate.

[0005] Specifically, the present invention provides a disc spring clamp, comprising: A cylindrical body with an opening at the top, and at least two sets of locking blocks spaced circumferentially on the inner wall of the cylindrical body, each set of locking blocks containing multiple locking blocks, the multiple locking blocks being spaced apart along the height direction of the cylindrical body; An installation plate is provided at the bottom of the cylinder. A first notch is provided around the perimeter of the installation plate. The position of the first notch corresponds to the position of the locking block group, so that the installation plate can avoid the multiple locking blocks during the up and down movement. The pressure plate has a shape corresponding to the opening shape of the cylinder. The pressure plate can move up and down in the cylinder along the height direction. A second notch is provided around the periphery of the pressure plate. The position of the second notch corresponds to the position of the locking block group so that the pressure plate can avoid the locking block during the up and down movement. The pressure plate is provided with an active channel connected to the second notch. The limiting component includes a movable block that is movable within the movable channel; The limiting component has a closed state and an open state. The closed state is when the movable block moves outward to the second notch and is adapted to be locked in the gap between two adjacent locking blocks. The open state is when the movable block moves inward away from the second notch and disengages from the gap so that the pressure plate can move up and down.

[0006] According to one embodiment of the present invention, the limiting component further includes a fixing post and a bending member. The fixing post is disposed at the center of the pressure plate. The bending member includes a pressing member and a connecting member. One end of the pressing member is fixed to the top of the fixing post, and the other end is connected to one end of the connecting member. The connecting member is disposed in the movable channel, and the other end of the connecting member is provided with the movable block.

[0007] According to one embodiment of the present invention, a limiting groove is formed on the pressure plate, the limiting groove is connected to the movable channel, and the other end of the pressing member extends into the limiting groove and is connected to one end of the connecting member.

[0008] According to one embodiment of the present invention, the side of the movable block away from the connector forms a downward arc surface.

[0009] According to one embodiment of the present invention, the fixing post is provided with a slot that cooperates with the pressing member.

[0010] According to one embodiment of the present invention, the bottom of the card slot is provided with an anti-slip surface.

[0011] According to one embodiment of the present invention, the top surface of the mounting plate is adapted to place the disc spring, and the bottom surface of the mounting plate is provided with a magnetic block for attracting the disc spring.

[0012] According to one embodiment of the present invention, a plurality of springs are provided between the mounting plate and the bottom of the cylinder, and the plurality of springs are evenly distributed along the circumference of the magnetic block.

[0013] According to one embodiment of the present invention, the cylinder is provided with an insertion hole.

[0014] According to one embodiment of the present invention, the at least two card block groups are evenly distributed along the circumference of the cylinder.

[0015] This invention provides a disc spring clamp that employs a limiting structure in which locking blocks are spaced apart along the height direction on the inner wall of a cylinder, and a second notch and movable channel corresponding to the locking blocks are provided on the pressure plate. The limiting structure utilizes the gap between the movable block and the locking blocks for engagement, eliminating the need for multiple parts such as bolts, nuts, and washers required for traditional bolt fastening, simplifying the overall structure and improving its compactness. The movable block can engage or disengage with the locking blocks simply by moving within the movable channel, allowing the limiting component to quickly switch between closed and open states. The pressure plate can be positioned at any height within the cylinder. The positional locking and smooth movement eliminate the need for repeated tightening and loosening of bolts, shortening clamp adjustment time and improving operational convenience. A movable block, positioned within the gap between adjacent blocks, creates a double-sided limit, which, combined with a pressure plate shaped to match the cylinder opening, provides stable pressure on the disc spring, preventing loosening and displacement due to thermal expansion and contraction during high-temperature creep experiments. This ensures uniform force on the disc spring and long-term stability of the experimental state. Overall, it achieves simplified, quick, and highly stable clamping and fixing of the disc spring, providing a reliable clamping structure for high-temperature creep experiments.

[0026] Figure 1 A schematic diagram of a disc spring clamp according to an embodiment of the present invention is shown. Figure 2 A cross-sectional view of a disc spring clamp according to an embodiment of the present invention is shown. As shown, the present invention provides a disc spring clamp 100, including a cylinder 110, a mounting plate 120, a pressure plate 130, and a limiting assembly 140. The top of the cylinder 110 is open, and at least two locking block groups 111 are provided on its inner wall. Each locking block group 111 includes multiple locking blocks 112 arranged at intervals along the height direction. The locking block groups 111 are distributed circumferentially on the inner wall of the cylinder 110, forming multiple height positions, providing a structural basis for multi-position positioning of the pressure plate 130. The use of locking blocks 112 instead of threads or bolts allows the locking positions to be directly formed by the gaps between the locking blocks 112, reducing the number of parts and reducing structural complexity. At the same time, the interval arrangement of the locking blocks 112 along the height direction naturally constitutes multiple selectable positioning positions of the pressure plate 130, allowing the pressure plate 130 to flexibly adjust its position according to the stacking height of the disc springs.

[0027] Mounting plate 120 is disposed at the bottom of cylinder 110 and is used to support disc springs. Mounting plate 120 has first notches 121 around its perimeter. The number of first notches 121 is the same as the number of locking blocks 111, and their positions correspond to those of the locking blocks 112, allowing mounting plate 120 to avoid locking blocks 112 during vertical movement. Specifically, the purpose of the first notches 121 is to allow mounting plate 120 to move smoothly along the height direction of cylinder 110 without being obstructed by locking blocks 112, thus accommodating stacks of different numbers of disc springs. The width of the first notches 121 should be sufficient to allow locking blocks 112 to pass through, ensuring the freedom of movement and positional adjustability of mounting plate 120 within cylinder 110.

[0028] The shape of the pressure plate 130 corresponds to the opening shape of the cylinder 110, allowing it to move up and down within the cylinder 110 and forming an approximate fit with the inner wall of the cylinder 110, providing a uniform pressing surface for the disc spring. A second notch 131 is provided around the periphery of the pressure plate 130. The number and position of the second notches 131 correspond to the locking block assembly 111, ensuring that the pressure plate 130 avoids the locking block 112 during movement. The pressure plate 130 also has a movable channel 132 communicating with the second notch 131, used to accommodate the movable block 141 of the limiting assembly 140. The width of the second notch 131 is greater than the width of the locking block 112, ensuring that the pressure plate 130 can smoothly pass through the position of the locking block 112. Simultaneously, this width difference provides movement space for the movable block 141, allowing it to extend outward along the movable channel 132 into the gap of the locking block 112 for engagement, or retract inward to disengage from the gap of the locking block 112 for unlocking.

[0029] The limiting component 140 includes a movable block 141, which can move within the movable channel 132. The limiting component 140 has a closed state and an open state. In the closed state, the movable block 141 moves outward to the second notch 131 and engages in the gap between two adjacent locking blocks 112. The upper end face of the movable block 141 abuts against the lower end face of the upper locking block 112, thereby locking the position of the pressure plate 130 and preventing the pressure plate 130 from moving upward. In the open state, the movable block 141 moves inward away from the second notch 131 and disengages from the gap, allowing the pressure plate 130 to move up and down. The engagement between the movable block 141 and the locking blocks 112 replaces the traditional bolt fastening. The spacing of the locking blocks 112 along the height direction enables multi-position rapid positioning of the pressure plate 130. At the same time, the inward and outward movement of the movable block 141 enables rapid switching between locking and unlocking, and the operation can be completed without the need for external tools.

[0030] The disc spring clamp 100 eliminates the need for multiple parts such as bolts, nuts, and washers required for traditional bolt fastening by using a locking block assembly 111 on the inner wall of the cylinder 110, a corresponding notch and movable channel 132 on the pressure plate 130, and a locking engagement between the movable block 141 and the locking block 112. This makes the overall structure simpler and more compact, and also avoids the problem of loosening and failure of threaded connections due to thermal expansion and contraction in high-temperature environments. The movement of the movable block 141 within the movable channel 132 enables quick engagement or disengagement with the locking block 112. The limiting component 140 can quickly switch between closed and open states, and the pressure plate 130 can be positioned and locked or move smoothly at any height within the cylinder 110 without repeatedly loosening and tightening bolts, significantly shortening the clamp adjustment time and improving operational convenience. In this example, two locking blocks correspond to two movable blocks 141. The movable blocks 141 are engaged within the gap between adjacent locking blocks 112 to form a double-sided limiting mechanism. Together with the pressure plate 130, whose shape corresponds to the opening of the cylinder 110, they provide stable upper and lower clamping for the disc spring, preventing loosening and displacement caused by thermal expansion and contraction of the material during the high-temperature creep experiment. This ensures uniform force on the disc spring and long-term stability of the experimental state. Overall, this achieves a simplified, quick, and highly stable clamping and fixing of the disc spring, providing a reliable fixture structure for high-temperature creep experiments on disc springs.

[0031] In some examples, the limiting assembly 140 also includes a fixed post 142 and a bent component 143. The fixed post 142 is located at the center of the pressure plate 130, serving as the mounting base and operating fulcrum for the bent component 143. The bent component 143 includes a pressing component 1431 and a connecting component 1432. One end of the pressing component 1431 is fixed to the top of the fixed post 142, and the other end is connected to one end of the connecting component 1432. The connecting component 1432 is located within the movable channel 132, and the other end of the connecting component 1432 is provided with a movable block 141. The structure using the fixed post 142 and the bent component 143 converts the operator's pressing action into linear movement of the connecting component 1432 and the movable block 141. The deformation of the pressing component 1431 drives the movable block 141 to switch between inward and outward positions, resulting in a compact structure and direct transmission. During operation, the operator presses the pressing element 1431 to bring it closer to the fixed post 142. The pressing element 1431 drives the connecting element 1432 to move, thereby causing the movable block 141 to move inward within the movable channel 132 and disengage from the gap of the locking block 112. At this time, the pressure plate 130 can move smoothly up and down. When the pressing element 1431 is released, the elastic recovery of the pressing element 1431 causes the connecting element 1432 to move in the opposite direction, causing the movable block 141 to extend outward and enter the gap of the locking block 112 to form a lock, achieving quick locking.

[0032] In some examples, a limiting groove 133 is formed on the pressure plate 130, which communicates with the movable channel 132. The other end of the pressing member 1431 extends into the limiting groove 133 and connects to one end of the connecting member 1432. In this example, the movable channel 132 is arranged radially, and the length direction of the limiting groove 133 is consistent with the radial direction. The limiting groove 133 is used to limit the movement path and range of the end of the pressing member 1431, preventing the end of the pressing member 1431 from deviating or dislodging during operation. At the same time, the displacement of the pressing member 1431 is reliably transmitted to the movable block 141 through the connecting member 1432, making the movement trajectory of the movable block 141 controllable. The movable channel 132 is used to limit the movement direction of the connecting member 1432, ensuring that the connecting member 1432 drives the movable block 141 to move along a predetermined straight line, avoiding the movable block 141 from deviating or getting stuck in the movable channel 132.

[0033] In some examples, the side of the movable block 141 furthest from the connector 1432 forms a downward-facing arc. The purpose of this arc is that when the pressure plate 130 slides downward, the arc first contacts the upper edge of the locking block 112. The guiding effect of the arc causes the locking block 112 to generate an inward component force on the movable block 141, pushing the movable block 141 to automatically move inward and retract into the movable channel 132. The pressure plate 130 can then smoothly pass through the position of the locking block 112 without applying greater pressing force. At the same time, the upper surface of the movable block 141 remains flat. When the movable block 141 extends outward under the action of elastic restoring force and engages with the gap of the locking block 112, this flat surface abuts against the lower surface of the upper locking block 112, forming a reliable mechanical limit, preventing the pressure plate 130 from coming off upward in the clamped state, and improving the stability and safety of the engagement state.

[0034] In some examples, the fixed post 142 is provided with a slot 144 that mates with the pressing member 1431. The slot 144 can form a structural fit with a part of the pressing member 1431. When the pressing member 1431 is deformed under pressure and fits against the slot 144, the slot 144 provides positioning support for the pressing member 1431, keeping the pressing member 1431 in a stable posture during operation. This prevents the pressing member 1431 from excessively shifting or twisting under force, making it easier for the operator to grasp the limiting component 140 as a whole and move the pressure plate 130 up and down. It also provides a clear pressing position indication for the pressing member 1431. Preferably, the bottom of the slot 144 is provided with an anti-slip surface 145. The anti-slip surface 145 is provided to increase the friction between the slot 144 and the pressing part 1431 or the finger, to prevent slippage during gripping or operation, and to improve the safety and stability of operation. In particular, when force needs to be applied to move the pressure plate 130 up and down, a reliable grip can prevent the clamp from accidentally slipping out of the hand.

[0035] In some examples, the top surface of the mounting plate 120 is suitable for placing the disc spring, and the bottom surface of the mounting plate 120 is provided with a magnet 150 for attracting the disc spring. Using the magnet 150 to attract the disc spring utilizes magnetic force to fix it to the top surface of the mounting plate 120 during installation, preventing displacement or tilting of the disc spring during placement or adjustment, ensuring accurate installation and operational safety. The attraction force of the magnet 150 can also resist minor external disturbances, keeping the disc spring in a stable position before the pressure plate 130 is pressed down.

[0036] In some examples, multiple springs 160 are provided between the mounting plate 120 and the bottom of the cylinder 110, and the springs 160 are evenly distributed circumferentially along the magnetic block 150. The springs 160 provide elastic support for the mounting plate 120, enabling the mounting plate 120 to float vertically within the cylinder 110. When the pressure plate 130 presses down on the disc springs, the springs 160 deform under pressure and accumulate elastic force, which can buffer the mounting plate 120 and avoid rigid impact. Even if the pressure plate 130 tilts during the downward pressing process, the difference in elastic force among the springs 160 can adaptively adjust the posture of the mounting plate 120, making the mounting plate 120 tend to be horizontal, thereby making the force on the disc springs more uniform. The uniform distribution of the springs 160 also ensures that the mounting plate 120 is balanced in all directions, preventing the mounting plate 120 from shifting or jamming.

[0037] In some examples, the cylinder 110 is provided with an insertion hole 113. The insertion hole 113 penetrates the side wall of the cylinder 110 and is used for inserting a temperature probe into the interior of the cylinder 110, allowing the experimenter to monitor the temperature environment inside the cylinder 110 at any time, ensuring that the high-temperature creep experiment is carried out accurately under the set temperature conditions. The insertion hole 113 is usually located near the disc spring so that the temperature probe can be close to the disc spring being tested, obtain more accurate temperature data, and make temperature monitoring convenient and direct, without the need to open the clamps.

[0038] In some examples, at least two locking block sets 111 are evenly distributed along the circumference of the cylinder 110. Evenly arranging the locking block sets 111 along the circumference of the inner wall of the cylinder 110 ensures that the locking support points of the pressure plate 130 are consistent in all directions, resulting in balanced force on all positions of the pressure plate 130 circumferentially. This prevents the pressure plate 130 from tilting or warping due to unilateral force, and improves the levelness of the pressure plate 130 and the uniformity of force on the disc spring during clamping. The even circumferential distribution of multiple locking block sets 111 also makes the alignment operation of the second notch 131 with the locking block sets 111 more intuitive, reducing the difficulty of assembly alignment.

[0039] Compared with the prior art, the disc spring clamp provided by this invention has the following advantages: 1. The clamping structure of the inner wall of the cylinder and the movable block on the pressure plate is used to replace the traditional bolt fastening method. This eliminates multiple connecting parts such as bolts, nuts, and washers, making the overall structure of the fixture simpler and more compact. The number of parts is significantly reduced, which lowers the manufacturing and assembly costs and cumulative tolerances. At the same time, it avoids the problem of loosening of the fit caused by thermal expansion and contraction of materials in the high temperature creep test environment.

[0040] 2. The locking and unlocking of the pressure plate is achieved by the locking and unlocking of the movable block between adjacent locking blocks. Multiple positioning positions are naturally formed by the spacing of the locking blocks along the height direction. The pressure plate can be quickly fixed or smoothly moved at any height position in the cylinder without the need for repeated loosening and tightening of bolts with external tools. The switching operation of the clamp state can be completed with one hand, which greatly shortens the time for replacing disc springs and adjusting height, and improves the convenience and efficiency of experimental operation.

[0041] 3. By using movable blocks to lock within the gap between the blocks to form double-sided mechanical limits, combined with pressure plates whose shape corresponds to the opening of the cylinder, a stable upper and lower clamping is formed for the disc spring. The clamping structure is not affected by temperature changes, and the clamping state is reliable and durable. It can effectively prevent the pressure plate from shifting or loosening due to thermal expansion and contraction during high-temperature creep experiments, ensuring that the disc spring is subjected to uniform force and remains stable throughout the entire experimental cycle, thereby improving the accuracy and repeatability of the experimental results.

[0042] 4. A magnetic block is installed at the bottom of the mounting plate to attract and fix the disc spring. Multiple springs work together to provide elastic support and posture balance for the mounting plate. The magnetic block can prevent the disc spring from shifting during installation, while the springs can buffer the downward pressure and keep the mounting plate self-adaptively level. Even if the pressure plate tilts slightly when it is pressed down, the difference in the spring force can adjust the posture of the mounting plate, making the force on the disc spring more uniform in all directions, which further improves the stability of clamping and the reliability of experimental data.

[0043] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments described above without departing from the spirit and scope of the invention. Therefore, it is intended that this invention cover modifications and variations falling within the scope of the appended claims and their equivalents.
