Description

TECHNICAL FIELD

[0001] The present application relates to the field of load technology, in particular to a load mechanism for sliding. BACKGROUND

[0002] In automated production lines, precision test platforms and material conveying systems, sliding mechanisms are widely used to achieve linear reciprocating motion of workpieces or loads. In order to improve the test accuracy of such systems, simulate real working conditions or achieve precise positioning, it is often necessary to apply controllable loads such as frictional resistance, constant pressure or loads simulating specific mechanical environments on the sliding table.

[0003] Traditional load application methods usually install load generating mechanisms (such as air cylinders, force application units driven by servo motors) independently on the outside of the sliding table or on the side of the motion path. This layout has several obvious disadvantages: first, it increases the overall volume and floor space of the equipment, which is not conducive to system integration and miniaturization design; second, the external load mechanism and its connecting components may interfere with other peripheral equipment or operating space, reducing the flexibility of system layout; third, if the motion direction of the load mechanism is not consistent with the motion direction of the sliding table, it may cause force decomposition, reducing the loading efficiency and control accuracy, and the complex transmission structure also increases mechanical losses and maintenance costs. In addition, some external load mechanisms are completely exposed, which is easy to accumulate dust or collide accidentally, affecting their long-term stability and service life.

[0004] Therefore, the industry needs a sliding mechanism with a more compact structure, higher integration and stable and efficient load to solve the problems of large space occupation, inflexible layout, low force transmission efficiency and poor protection caused by traditional layout methods. CONTENT OF THE INVENTION

[0005] The present application proposes a load mechanism for sliding, aiming to optimize the structural layout and force transmission efficiency of traditional sliding loading devices.

[0006] Specifically, the load mechanism for sliding hides the load assembly entirely under the sliding table and directly applies controllable load to the sliding table by the driving device and the friction loading part perpendicular to the sliding direction of the sliding table. It can highly integrate the load mechanism and the sliding body, thereby significantly reducing the overall space occupation, avoiding external interference, improving the directionality and stability of force transmission, and ultimately enhancing the loading accuracy, structural compactness and environmental adaptability of the sliding mechanism.

[0007] The load mechanism for sliding provided by the present application adopts the following technical solutions:

[0008] A sliding load mechanism includes: a base; a moving component disposed on the base, including a first mounting plate, a second mounting plate, a first slide rail and a second slide rail disposed on the first mounting plate, and a slide table slidably disposed on the first slide rail and the second slide rail; and a load component disposed below the slide table and completely shielded by the slide table, including a driver and a friction loading part, wherein the driver is motive-connected to the friction loading part, and the axial directions of the driver and the friction loading part are both perpendicular to the sliding direction of the slide table.

[0009] By adopting the above technical solution, the slide table slides linearly along the first and second slide tracks mounted on the first mounting plate. The load assembly is integrated entirely within the space directly below the slide table. When the driver is activated, it drives the friction loading part (such as a friction roller) connected to it to move linearly perpendicular to the sliding direction of the slide table, thereby applying precise and controllable normal pressure or friction force to the bottom or side of the slide table, realizing dynamic load application or motion damping adjustment of the slide table. By completely concealing the drive and loading units within the projected space below the slide table, the occupation and interference of the surrounding space by traditional external load mechanisms are fundamentally eliminated, achieving an extremely compact equipment structure. Simultaneously, the perpendicular orthogonal design of the load application direction and the motion direction ensures that the load force is transmitted along the most direct path, avoiding unnecessary force decomposition losses and significantly improving loading efficiency, control accuracy, and dynamic response performance. The enclosed built-in structure also provides comprehensive physical protection for the load assembly, effectively isolating it from external contamination and mechanical interference, enhancing the system's environmental adaptability and long-term operational reliability.

[0010] Preferably, the base has heat dissipation holes between the first mounting plate and the second mounting plate.

[0011] Preferably, the first mounting plate and the second mounting plate are respectively connected to a third mounting plate and a fourth mounting plate at both ends to enhance the overall stability of the structure.

[0012] Preferably, the friction loading part includes a guide mounting plate, and roller rods are provided on both sides of the guide mounting plate, with friction rollers rotatably connected to the roller rods.

[0013] Preferably, at least three sets of friction rollers are provided.

[0014] Preferably, the actuator is an electric cylinder, which includes a telescopic rod and guide rings disposed on both sides of the telescopic rod; the friction loading part includes a guide mounting plate, which is connected to the telescopic rod, and guide rods are provided on both sides of the guide mounting plate, with the guide rings cooperating with the guide rods.

[0015] Preferably, the width of the friction loading part is smaller than the width of the slide.

[0016] Preferably, the thickness of the third mounting plate and the fourth mounting plate is less than the thickness of the first mounting plate and the second mounting plate.

[0017] Preferably, the inner walls of the first mounting plate and / or the second mounting plate are coated with a friction coating.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. Compact structure and optimized space utilization: By fully integrating and hiding the load components directly under the slide, the three-dimensional integration of the drive unit, loading mechanism and motion platform is achieved, completely eliminating the occupation and interference of the surrounding space by the traditional external load mechanism, and providing an innovative solution for equipment miniaturization and high-density layout.

[0020] 2. Significantly improved load control accuracy and dynamic response performance: The structural design of the actuator and friction loading part being axially perpendicular to the slide movement direction allows the load force to be directly transmitted along a straight path, avoiding the force decomposition loss and response delay caused by traditional oblique or lateral loading methods; combined with the linear precision drive of the electric cylinder and the multi-roller symmetrical uniform loading mechanism, stepless, linear, and highly stable precise adjustment of the load force is achieved, greatly improving the accuracy of motion control and the quality of dynamic response.

[0021] 3. Enhanced system reliability, stability, and environmental adaptability: The built-in enclosed structure provides comprehensive physical protection for the load components, effectively isolating them from the effects of external dust, chips, and mechanical collisions; the targeted heat dissipation channels on the base ensure the thermal stability of key drive components; further improvements are made through the reinforcement of the mounting plate, the anti-eccentric load design of the guide mechanism, and the application of friction-functional coatings, thereby enhancing the overall system's operational reliability and environmental adaptability under long-term high-load and high-frequency conditions.

[0025] The following is in conjunction with the appendix Figure 1 and Figure 2 This application will be described in further detail.

[0026] This application discloses a sliding load mechanism.

[0027] Reference Figure 1 and Figure 2 It includes a base 1, a moving component 2 and a load component 3, which are used to achieve a highly integrated and concealed arrangement of the loading function. The moving component 2 is set on the base 1, and the load component 3 is set under the moving component 2, so that the load component 3 is completely covered by the moving component 2.

[0028] The movable component 2 includes a first mounting plate 21, a second mounting plate 22, a first slide rail 23 mounted on the first mounting plate 21, and a second slide rail 24 mounted on the second mounting plate 22. The base 1 is connected in the middle by bolts to two parallel mounting plates, namely the first mounting plate 21 and the second mounting plate 22. The two slide rails are bolted parallel to each other to the upper side of the first mounting plate 21 and the second mounting plate 22, and are called the first slide rail 23 and the second slide rail 24. Each set of slide rails is equipped with an independent slider. The slide table 25 is bolted to the top of the two sets of sliders.

[0029] The load assembly 3 includes a driver 31 and a friction loading part 32. As the key to achieving precise loading, the driver 31 is a high-precision electric cylinder. The driver 31 and the friction loading part 32 are connected in a transmission manner and are installed with their axial directions perpendicular to the sliding direction of the slide table 25.

[0030] The front telescopic end of the actuator 31 is fitted with a slide block for bolting to the slide table 25. Guide rings 311 are formed on both sides of the slide block. The electric cylinder itself has a telescopic rod. The friction loading part 32 includes a guide mounting plate 321, which is bolted to the telescopic rod. Guide rods 324 are provided on both sides of the guide mounting plate 321. The guide rings 311 and guide rods 324 are inserted and guided. Roller rods 322 are inserted and bolted to the upper and lower sides of the guide mounting plate 321. Friction rollers 323 are rotatably connected to the roller rods 322. Five sets of friction rollers 323 are symmetrically arranged. The friction loading part 32 consists of five sets of symmetrically distributed friction rollers 323 forming its working body and is linked with the output end of the electric cylinder. Under the telescopic drive of the electric cylinder, the friction rollers 323 apply controllable pressure to the mounting surface on the side of the slide, thereby applying precisely adjustable rolling friction resistance to the movement of the slide table 25. This design utilizes the linear thrust provided by the electric cylinder to achieve stepless precision control of the load force. Furthermore, the friction loading section 32 employs a structure combining a guide mounting plate 321 and dual-sided roller rods 322, with its five sets of rollers symmetrically arranged, effectively enhancing the system's motion stability while ensuring uniform load distribution. The electric cylinder integrates a dual guide ring 311 structure, which, through precise cooperation with the loading section guide rod 324, ensures the linearity and accuracy of the power output. In addition, the overall width of the friction loading section 32 is optimized to be smaller than the width of the slide table 25, allowing it to be completely hidden within the projection range of the slide table 25, achieving a compact and concealed structure.

[0031] The slide table 25 slides linearly along the first slide rail 23 and the second slide rail 24 mounted on the first mounting plate 21. The load assembly 3 is integrated into the space directly below the slide table 25. When the driver 31 is activated, it drives the friction loading part 32 (such as the friction roller 323) connected to it to move linearly along the sliding direction of the slide table 25, thereby applying a precise and controllable normal pressure or friction force to the bottom or side of the slide table 25, realizing the dynamic load application or motion damping adjustment of the slide table 25. By completely hiding the drive and loading units in the projection space below the slide table 25, the occupation and interference of the surrounding space by the traditional external load mechanism is fundamentally eliminated, achieving an extremely compact equipment structure. At the same time, the perpendicular orthogonal design of the load application direction and the motion direction allows the load force to be transmitted along the most direct path, avoiding unnecessary force decomposition loss, and significantly improving loading efficiency, control accuracy, and dynamic response performance. The enclosed built-in structure also provides comprehensive physical protection for the load component 3, effectively isolating it from external pollution and mechanical interference, and enhancing the system's environmental adaptability and long-term operational reliability.

[0032] Furthermore, in this embodiment, the base 1 has heat dissipation holes 11 corresponding to the load area, which utilize air convection to dissipate the working heat of the electric cylinder in a timely manner, ensuring stable temperature control and system reliability during continuous operation.

[0033] Furthermore, in this embodiment, the first mounting plate 21 and the second mounting plate 22 are respectively bolted to the two ends of a third mounting plate and a fourth mounting plate to enhance the overall stability of the structure.

[0034] Furthermore, in this embodiment, the thickness of the third mounting plate and the fourth mounting plate is less than the thickness of the first mounting plate 21 and the second mounting plate 22.

[0035] Furthermore, in this embodiment, the friction rollers 323 may be in three or four sets.

[0036] Furthermore, in this embodiment, the inner walls of the first mounting plate 21 and / or the second mounting plate 22 are coated with a friction coating.

[0037] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
