Description

Technical Field

[0001] The utility model belongs to the technical field of sliding support systems, and particularly relates to a sliding support system with adjustable supporting force. Background Art

[0002] Linear guide pairs are key components widely used in various mechanical equipment. Their main characteristics are high precision, excellent adaptability, and good interchangeability. A linear guide pair usually consists of a guide rail and a slider. The guide rail is fixed on the machine body, and the slider is fixed on the sliding body, so as to realize the relative sliding between the two. In the traditional structure of a linear guide pair, the position relationship between the slider and the guide rail in the normal direction (vertical direction) is usually fixed, making it impossible to achieve relative movement or adjustment in the normal direction between the sliding body and the machine body. This fixed position relationship can provide stable support and precise linear movement in most applications, but in some occasions that require normal adjustment or precise positioning, its adaptability and flexibility are insufficient.

[0003] Existing linear guide pairs usually cannot meet the special application requirements where there is a compressible normal gap between the sliding body and the machine body. For example, in some machine tools or systems that require adjusting the supporting force, the limitation of the normal rigidity between the slider and the guide rail causes no relative movement between the sliding body and the machine body, thus resulting in different supporting forces to support sliding bodies of different masses.

[0004] Therefore, it is necessary to design a sliding support system with adjustable supporting force to solve the above problems existing in the prior art. Summary of the Utility Model

[0005] Details of one or more embodiments of the present utility model are set forth in the following drawings and description, so as to make other features, objects, and advantages of the present application more concise and understandable.

A plurality of elastic members and a fixing plate are sequentially sleeved on the central shaft from bottom to top. The fixing plate is connected to the sliding body. The fixing plate pre-compresses the elastic members through a limiting device. There is a gap between the machine body and the sliding body, and the distance of the gap is the difference between the total compression stroke and the pre-compression stroke of the elastic members.

[0008] In some embodiments, the limiting device is a limiting ring fixedly arranged on the central shaft, and the limiting ring is located above the fixing plate.

[0009] In some embodiments, the support assembly further includes an upper flat washer and a lower flat washer. The upper flat washer is sleeved on the central shaft, and the upper flat washer is arranged between the fixing plate and the elastic member.

[0010] In some embodiments, the support assembly further includes a bearing. The bearing is sleeved between the central shaft and the fixing plate, and relative movement occurs between the fixing plate and the central shaft.

[0011] In some embodiments, the support assembly further includes a sleeve. The sleeve is sleeved outside the plurality of elastic members and the lower flat washer.

[0012] In some embodiments, the elastic member is a disc spring, and a plurality of the disc springs are arranged in a superposed, opposed or combined manner of superposition and opposition.

[0013] In some embodiments, a threaded hole is provided at one end of the central shaft away from the sliding block, and a through hole is provided on the limiting ring.

[0014] In some embodiments, a plurality of first connection holes are provided on the fixing plate, and the fixing plate is fixedly connected to the sliding body through a second fastener.

[0015] In some embodiments, the sliding support system further includes an elastic member base. The elastic member base is arranged on the sliding block, and the central shaft is inserted into the elastic member base. A plurality of second connection holes are provided on the elastic member base, and the elastic member base is fixedly connected to the sliding block through the second fastener.

[0016] In some of these embodiments, a second elastic washer is provided between the second fastener and the fixed plate, and a second elastic washer is provided between the second fastener and the elastic member base.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. The present utility model discloses a sliding support system with adjustable supporting force. The typical structure of a traditional linear guide pair is to fix the guide rail on the machine body, and the slider is fixed on the sliding body, so as to realize the sliding of the sliding body relative to the machine body. However, in the design of traditional linear guide pairs, a fixed normal position relationship is maintained between the slider and the guide rail, resulting in a fixed normal position relationship between the sliding body and the machine body, and the relative movement in the normal direction cannot be realized. This structure will limit the flexibility of the system in some application scenarios. Especially when the normal supporting force needs to be adjusted, the traditional linear guide pair cannot meet such requirements; in order to realize the relative movement in the normal direction and the adjustment of the supporting force between the sliding body and the machine body, an improved sliding support system is needed. In the present utility model, the sliding body and the machine body do not directly contact each other, but are arranged at intervals, and there is a certain gap between the two through the elastic member. This design increases the adjustment space of the system, increases the adjustment function of the normal supporting force, solves the problem of the fixed position relationship between the sliding body and the machine body, and provides a more flexible and efficient solution for the adjustment of the supporting force.

[0019] 2. The present utility model sets a support assembly between the slider and the sliding body, wherein a plurality of elastic members are defined between the fixed plate and the slider and generate a reaction force when stressed, tightly fitting the fixed plate connected with the sliding body to the lower plane of the limiting ring. Since the limiting ring is fixedly connected to the central axis, the limiting ring remains stationary, and the reaction force of the elastic member acts on the fixed plate, so that a certain gap is always maintained between the sliding body and the machine body. When the sliding body is subjected to an external force, the elastic member is further compressed, and a relative movement occurs between the fixed plate and the central axis, thereby eliminating the original gap and providing a greater supporting force for the sliding body, realizing the adjustment of the supporting force. This method effectively solves the problem that the supporting force cannot be adjusted in the traditional sliding support system.

[0020] 3. In the present utility model, the central axis is vertically arranged on the slider as the main axis of the support assembly, the fixed plate is connected to the sliding body and is arranged at intervals with the slider. By adjusting the installation and arrangement modes of a plurality of elastic members, the flexible adjustment of the supporting force is realized. Users can replace elastic members with different stiffnesses or arrangement modes according to the actual use situation, so as to meet the requirements of different working conditions. This structural design significantly improves the adaptability and use efficiency of the system, enabling the sliding support system to not only provide a stable supporting force, but also automatically adjust the supporting force when the external force changes to maintain the stability and performance of the system.

[0021] 4. In the present utility model, the elastic member is preferably a disc spring, which is arranged in a manner of stacking, butting or a combination of stacking and butting. This structure can not only provide a linearly or non-linearly adjustable supporting force, but also has a high load-bearing capacity and a long service life. The upper flat washer and the lower flat washer in the support system are sleeved on the central shaft and are respectively located between the fixing plate and the elastic member, and between the elastic member and the elastic member base. The setting of these flat washers further optimizes the stress state of the elastic member, reduces the local stress concentration of the elastic member, and improves the overall stability and reliability of the system.

[0022] 5. The limiting ring provided in the support assembly of the present utility model is fixedly connected to the central shaft through the first fastener, and a first elastic washer is added between the limiting ring and the fastener to enhance the anti-vibration and anti-impact capabilities of the connection. This connection method ensures the stable operation of the system in a complex working environment and avoids the support failure caused by the loosening of the fastener. At the same time, the fixing plate and the sliding body, and the elastic member base and the slider are connected through the second fastener, and a second elastic washer is provided at the connection to further improve the anti-fatigue ability and durability of the system.

[0023] 6. The support assembly of the present utility model may further include a bearing, which is sleeved between the central shaft and the fixing plate, enabling the fixing plate to move relative to the central shaft, thereby reducing friction, lowering energy consumption, and improving the movement smoothness of the system. In addition, the sleeve in the support assembly wraps multiple elastic members and the lower flat washer, providing additional protection to prevent foreign objects from entering the gaps between the elastic members and affecting the system performance, further enhancing the protection ability and working stability of the system.

Detailed implementation manners

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be described and explained below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided by the present invention without making creative efforts belong to the scope of protection of the present invention.

[0035] The embodiment of the present invention provides a sliding support system with adjustable supporting force. Refer to Figures 1 to 8As shown, the sliding support system is arranged between the body B and the sliding body A, and at least includes a slider 1 and a support assembly 2; the slider 1 drives the sliding body A to move horizontally on the body B; the support assembly 2 is arranged between the slider 1 and the sliding body A, and the support assembly 2 includes a central axis 201 vertically arranged on the slider 1, and a plurality of elastic members 203 and a fixing plate 202 are sequentially sleeved on the central axis 201 from bottom to top, and the fixing plate 202 is connected to the sliding body A; the fixing plate 202 pre-compresses the elastic members 203 through a limiting device, and there is a gap between the body B and the sliding body A, and the distance of the gap is the difference between the total compression stroke and the pre-compression stroke of the elastic members 203. In the present utility model, the sliding body A and the body B are no longer in direct contact, but are arranged at intervals with a certain gap left. This design increases the adjustment space of the system, increases the adjustment function of the normal support force, solves the problem that the positional relationship between the sliding body A and the body B is fixed, and provides a more flexible and efficient support force adjustment solution. Among them, the setting of the limiting device is used to adjust the pre-compression amount of the elastic members 203, so as to adjust the magnitude of the support force, and the existence of the gap ensures that the system works within the elastic range of the elastic members 203.

[0036] Further, the limiting device is a limiting ring 204 fixedly arranged on the central axis 201, and the limiting ring 204 is located above the fixing plate 202. The limiting ring 204 is fixed on the central axis 201 and is located above the fixing plate 202, so as to limit the rising height of the elastic members 203 and realize the pre-compression control of the elastic members 203; a plurality of elastic members 203 are limited between the fixing plate 202 and the slider 1 and generate reaction forces when stressed. Due to the setting of the limiting ring 204, the fixing plate 202 connected with the sliding body A is closely attached to the lower plane of the limiting ring 204, and the reaction force of the elastic members 203 acts on the fixing plate 202, so that a certain gap is always maintained between the sliding body A and the body B. When the sliding body A is subjected to an external force, the elastic members 203 are further compressed, and relative movement occurs between the fixing plate 202 and the central axis 201, so as to eliminate the original gap and provide a greater support force for the sliding body A, realizing the adjustment of the support force. This method effectively solves the problem that the support force cannot be adjusted in the traditional sliding support system.

[0037] Furthermore, the support assembly 2 further includes an upper flat washer 206 and a lower flat washer 207; the upper flat washer 206 is sleeved on the central shaft 201, and the upper flat washer 206 is disposed between the fixed plate 202 and the elastic member 203; the lower flat washer 207 is sleeved on the central shaft 201, and the lower flat washer 207 is disposed between the elastic member 203 and the slider 1. In the present utility model, the upper flat washer 206 and the lower flat washer 207 in the support assembly 2 are respectively disposed at both ends of the elastic member 203, and flat washers are arranged at the upper and lower ends of the elastic member 203 to further evenly distribute the load. This kind of setting helps to extend the service life of the elastic member 203, and at the same time improves the overall rigidity and stability of the support assembly 2. The addition of the upper flat washer 206 and the lower flat washer 207 significantly improves the uniform distribution of the support assembly 2 under the action of the load, and avoids the early damage caused by excessive local force on the elastic member 203. Through the buffering effect of the flat washer, the overall rigidity of the support assembly 2 is enhanced, and the smoothness and durability of the system are improved. In addition, the presence of the upper and lower flat washers can also reduce the wear caused by the direct contact between the elastic member 203 and other components.

[0038] Furthermore, the support assembly 2 further includes a bearing 208, the bearing 208 is sleeved between the central shaft 201 and the fixed plate 202, and relative movement occurs between the fixed plate 202 and the central shaft 201. The setting of the bearing 208 significantly reduces the friction coefficient between the fixed plate 202 and the central shaft 201, thereby making the overall movement of the sliding support system smoother. At the same time, the use of the bearing 208 also reduces the wear in the sliding support system, and improves the durability and reliability of the sliding support system. This design also reduces the noise during operation and enhances the stability and user experience of the sliding support system.

[0039] In some embodiments, according to the specific load and operating environment, the bearing 208 can adopt different types, such as ball bearings, sliding bearings or self-lubricating bearings, etc., to adapt to different friction conditions and service life requirements. The size and material of the bearing 208 can also be adjusted according to actual needs. For example, in high-load applications, a bearing 208 made of high-strength steel is selected, and in occasions where weight reduction is required, lightweight materials can be selected.

[0040] Furthermore, the support component 2 further includes a sleeve 209 which is sleeved outside the plurality of elastic members 203 and the lower flat washer 207. In the present utility model, the sleeve 209 surrounds the plurality of elastic members 203 and the lower flat washer 207 together, playing a role of fixing and protecting. The arrangement of the sleeve 209 can not only prevent the elastic members 203 from undergoing lateral displacement or deformation when stressed, but also provide additional protection for the elastic members 203 to avoid direct damage to the elastic members 203 from the external environment. Reinforcing ribs or surface treatment can be added to the outer wall of the sleeve 209 to improve its strength and corrosion resistance. The addition of the sleeve 209 provides additional support and protection for the elastic members 203, enabling the elastic members 203 to maintain a stable state during the operation of the system and preventing accidental movement or damage of the elastic members 203. At the same time, the design of the sleeve 209 can prevent dust and water, effectively extending the service life of the elastic members 203. Through this structural improvement, the overall stability and durability of the sliding support system are significantly improved.

[0041] Furthermore, the elastic member 203 is a disc spring, and a plurality of disc springs are arranged in a superposed, opposed or combined manner of superposition and opposition. The disc spring is used as the elastic member 203, and it provides adjustable elastic support force through the superposed, opposed or combined arrangement. This arrangement of the disc springs can adjust the total elastic coefficient according to specific support requirements, thereby flexibly adjusting the magnitude of the support force. The superposed arrangement increases the support force, while the opposed arrangement can adjust the characteristics of elastic deformation, enabling the system to adapt to different load conditions. Using the disc spring as the elastic member 203 has higher rigidity and compactness compared with the traditional helical spring, and can provide a larger support force in a limited space. The diverse arrangement methods of the disc springs enable a wider adjustment range of the support force, which can be adjusted according to different usage requirements, improving the adaptability and practicality of the sliding support system.

[0042] When the sliding body A requires a larger or smaller support force, the adjustment of the support force can be achieved by replacing the type of the disc spring, increasing or decreasing the number of disc springs, and adopting the superposed, opposed and combined manner of superposition and opposition.

[0043] Further, a threaded hole 2011 is provided at one end of the central shaft 201 away from the slider 1, and a through hole 2041 is provided on the limiting ring 204. The first fastener 3 is threaded through the through hole 2041 and threadedly connected to the threaded hole 2011. A first elastic washer 4 is provided between the first fastener 3 and the limiting ring 204. A threaded hole 2011 is provided at one end of the central shaft 201 away from the slider 1, and a through hole 2041 is provided on the limiting ring 204, and they are threadedly connected through the first fastener 3. The first elastic washer 4 is provided between the first fastener 3 and the limiting ring 204. The compression characteristic of the elastic washer 4 provides an additional buffering effect, making the connection more firm and having a certain earthquake resistance. This design can reduce loosening caused by vibration and impact during the operation of the system, improving the overall stability and safety of the system. The threaded connection method of the first elastic washer 4 and the first fastener 3 can effectively prevent loosening of the connection part, enhancing the earthquake resistance and durability of the system. This design can not only provide reliable fixation during the connection process, but also absorb part of the vibration energy through the buffering effect of the elastic washer 4, reducing the operating noise. At the same time, the adjustability of the first fastener 3 also makes the adjustment of the supporting force more convenient and accurate.

[0044] Further, a plurality of first connection holes 2021 are provided on the fixing plate 202, and the fixing plate 202 is fixedly connected to the sliding body A through the second fastener 5. A plurality of first connection holes 2021 are provided on the fixing plate 202, allowing the fixing plate 202 to be firmly connected to the sliding body A through the second fastener 5. The design of the plurality of connection holes 2021 increases the connection points between the fixing plate 202 and the sliding body A, disperses the load, and improves the reliability and stability of the overall connection. The use of the second fastener 5 ensures the connection strength and provides a certain adjustment space for fine-tuning the position during installation, so as to ensure the precise docking and stable operation of the system.

[0045] Furthermore, the support assembly 2 further includes an elastic member base 205. The elastic member base 205 is connected to the slider 1, and the central shaft 201 is connected to the elastic member base 205. By adding the elastic member base 205, the structure of the support assembly 2 becomes more stable, effectively improving the support capacity and durability of the elastic member 203. The presence of the elastic member base 205 reduces the vibration transmission between the slider 1 and the fixed plate 202, further enhancing the seismic performance and service life of the system. At the same time, the design of the elastic member base 205 also facilitates the installation and maintenance of the entire sliding support system, making it more convenient to replace and adjust the elastic member 203. The elastic member base 205 is fixed to the slider 1 by the second fastener 5. This connection method ensures a firm connection between the elastic member base 205 and the slider 1, and effectively disperses the pressure when the elastic member 203 is stressed, preventing local stress concentration. The application of the second fastener 5 ensures the flexibility of installation, allowing the connection position to be adjusted appropriately according to the actual situation to ensure the stability of the sliding support system. The connection between the elastic member base 205 and the slider 1 through the distribution of multiple connection holes and fasteners effectively improves the connection stability and anti-vibration performance, reducing loosening and displacement caused by impact during operation. This design also makes the installation and maintenance process more convenient, further enhancing the reliability of the connection and ensuring the long-term stable operation of the sliding support system.

[0046] Furthermore, a second elastic washer 6 is provided between the second fastener 5 and the fixed plate 202, and a second elastic washer 6 is provided between the second fastener 5 and the elastic member base 205. The application of the second elastic washer 6 increases the buffering and shock absorption capacity of the system, effectively reducing the vibration and noise during system operation, while enhancing the connection stability and durability. This design can also improve the operating reliability of the system in an unstable environment, reducing connection loosening or failures caused by mechanical vibration.

[0047] The working process of the above-mentioned sliding support system with adjustable supporting force (specific application examples are as shown in Figure 7 and Figure 8 ) is as follows:

[0048] As shown in Figure 7 and Figure 8As shown, there is a gap t between the body B and the sliding body A. The sliding body A is supported by 4 sliding support systems with adjustable supporting forces. The disc springs in these sliding support systems are compressed within the space defined by the upper flat pad 206 and the lower flat pad 207. This compression uses the reaction force to closely attach the fixing plate 202 with the sliding body A to the lower plane of the limit ring 204. The height of the limit in each sliding support system is accurately and uniformly positioned by the central shaft 201. Therefore, the upper planes of the respective fixing plates 202 are coplanar with the lower plane of the limit ring 204, ensuring that the sliding body A and the body B are parallel to each other and the gap at each location is t. When the sliding body A is subjected to a horizontal external force under the action of the slider 1, the slider 1 will drive the sliding body A to move horizontally. When the sliding body A is subjected to a downward external force, this force will be transmitted through the fixing plate 202 to the upper flat pad 206 and further compress the disc spring. As the disc spring is compressed, relative sliding occurs between the fixing plate 202 and the central shaft 201, thereby eliminating the original gap t between the sliding body A and the body B. During this process, the disc spring provides a greater supporting force for the sliding body A. If the sliding body A requires a greater or smaller supporting force, the change of the supporting force can be achieved by replacing the type of the disc spring, increasing or decreasing the number of the disc springs, or adopting the ways of superposition, opposition, and the combination of superposition and opposition.

[0049] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0050] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
