Abstract
Description
Technical Field
[0001] The present application relates to the technical field of linear slides, and in particular to a support device for a linear slide. Background Art
[0002] Linear slides play a vital role in industrial automation, widely used in machining, assembly lines, material handling, and many other applications. Their primary function is to precisely move and position loads in a linear direction. However, existing linear slide support devices suffer from numerous technical deficiencies, making them unable to meet the stringent requirements of modern industry for high precision, stability, and reliability.
[0003] Traditional linear slide support devices often have simple structures, often employing rigid connections and lacking effective buffering and shock absorption mechanisms. During actual operation, linear slides are inevitably subject to various external interference forces, such as mechanical vibration and impact loads. Especially under high loads or high speeds, linear slides are susceptible to external shock and vibration, resulting in reduced stability and accuracy. While some support devices with simple buffering functions exist on the market, they typically provide only limited cushioning effect and lack coordination between the individual buffer units. Failure of a buffer unit can adversely affect the performance of the entire system. Utility Model Content
[0004] In order to solve the problem that traditional linear slide support devices can usually only provide limited buffering effects and lack mutual coordination between various buffer units, the present application provides a linear slide support device.
[0005] The support device of a linear slide provided in this application adopts the following technical solution:
[0006] A support device for a linear slide comprises a slide, a linear actuator is provided on the lower side of the slide for driving the slide to move in a straight line, a support plate is provided below the linear actuator, a plurality of guide assemblies are provided on the support plate in parallel with the outer side of the linear actuator for parallel guiding the slide, a base is provided on the lower side of the support plate, a plurality of buffer grooves are provided in the base, a buffer assembly is provided in the buffer groove, the buffer assembly comprises a support column provided below the support plate, and the support column can move along the Z axis, an elastic element is provided below the support column, and a hydraulic adjustment unit is provided on the outer side of the support column.
[0007] Preferably, the hydraulic adjustment unit includes a piston plate mounted on a support column, the piston plate is slidably arranged in a corresponding buffer groove, and a pressure relief valve and a negative pressure valve are provided on the support column for maintaining the hydraulic pressure below the piston plate within a threshold value.
[0008] Preferably, two adjacent buffer slots are connected to each other.
[0009] Preferably, the linear actuator includes a screw rod rotatably arranged on a support plate, a thread sleeve is provided on the screw rod for transmission, and the thread sleeve is detachably connected to the slide.
[0010] Preferably, the guide assembly includes a guide rail detachably provided on the support plate, a plurality of sliders are slidably provided on the guide rail, and the sliders are detachably connected to the bottom of the slide.
[0011] In summary, this application has the following beneficial technical effects:
[0012] Through the coordinated use of the base, buffer assembly and support plate, the buffer assembly is used to support the entire linear sliding system. During operation, when vibration or impact occurs, the support column is used to compress the spring, and at the same time, the piston plate compresses the hydraulic oil under the support column, so that the pressure exceeds the set value of the pressure relief valve. The hydraulic oil reaches the top of the piston plate through the pressure relief valve to achieve hydraulic buffering. When the spring pushes the support column to drive the pressure relief valve to move upward, the negative pressure valve draws the hydraulic oil above the piston plate to the bottom side of the piston plate to achieve smooth protection. Compared with the existing technology, it has the effects of high stability and high support strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is combined with Figure 1-3 This application is described in further detail.
[0018] The embodiment of the present application discloses a support device for a linear slide. Figure 1-3A linear slide support device includes a base 1 with a plurality of buffer grooves evenly distributed on the base 1. Each buffer groove contains a buffer assembly 2, which includes a piston plate 203 slidably mounted within the groove. Adjacent buffer grooves are connected by a flow channel. This ensures uniform pressure across the buffer grooves, preventing failure of a single buffer assembly 2 from affecting overall operation.
[0019] Reference Figure 3 A support column 201 is fixedly mounted on the piston plate 203, and an elastic element, such as a spring 202, is mounted at the lower end of the support column 201 to cope with larger impact forces. The stiffness of the spring is reasonably designed according to the load and running speed of the linear slide to ensure that sufficient deformation can be generated to buffer energy when subjected to impact, while at the same time being able to quickly return to its original state to ensure the stability of the linear slide. Two channel holes are provided on the piston plate 203, and a pressure relief valve 204 and a negative pressure valve 205 are respectively installed in the two channel holes. The maximum value of the oil pressure below the piston plate 203 in the buffer groove is controlled by the pressure relief valve 204, and the minimum value of the oil pressure below the piston plate 203 in the buffer groove is controlled by the negative pressure valve 205, so as to realize the threshold range of controlling the buffer pressure. It is reasonably designed according to the load and running speed of the linear slide to ensure that it can withstand impact and protect the linear slide and the support device from damage.
[0020] Reference Figure 2 The upper ends of several support columns 201 pass through the upper wall of the buffer tank and are connected to the same support plate 3. A sealing structure is added between the support columns 201 and the upper wall of the buffer tank to ensure the sealing of the connection.
[0021] Reference Figure 3 A linear actuator 4 is mounted on the support plate 3. This linear actuator 4 includes a screw 401 rotatably mounted on the base 1. A threaded sleeve 402 is mounted on the screw 401. A slide 6 is removably connected to the threaded sleeve 402, for example, by bolts. Several guide assemblies 5 are mounted on either side of the screw 401 on the support plate 3. These guide assemblies 5 include guide rails 501 mounted on the support plate 3. Several sliders 502 are slidably mounted on the upper ends of the guide rails 501. The sliders 502 are removably connected to the slide 6, for example, by bolts. The number of sliders 502 is appropriately designed based on the load and operating speed of the linear slide.
[0022] The implementation principle of the support device of a linear slide in the embodiment of the present application is as follows:
[0023] The screw rod 401 of the linear actuator 4 starts to rotate, driving the wire sleeve 402 to move along the screw rod. The movement of the wire sleeve 402 pushes the support plate 3 to move upward or downward, thereby driving the slide 6 to slide along the guide rail 501.
[0024] During movement, the slide 6 may be subject to external shock or vibration. The impact force is transmitted to the piston plate 203 of each buffer assembly 2 through the support plate 3. The piston plate 203 moves up and down within the buffer groove, compressing or stretching the spring 202 to absorb the impact energy. The oil in the buffer groove flows between the various buffer grooves through the flow channel, ensuring that the pressure in each buffer groove is the same, thereby preventing the failure of a single buffer assembly from affecting the overall performance. When the oil pressure in the buffer groove exceeds the set value of the pressure relief valve 204, the pressure relief valve 204 opens, releasing the excess pressure and preventing overpressure from damaging the equipment.
[0025] The piston plate 203 returns to its initial position under the action of the spring 202. When the oil pressure in the buffer tank is lower than the set value of the negative pressure valve 205, the negative pressure valve 205 opens and the oil above returns to the bottom to ensure the buffering effect.
