Description

Technical Field

[0001] This utility model relates to the field of guide rail manufacturing technology, specifically to a linear intelligent guide rail mechanism for aerospace equipment. Background Technology

[0002] A guide rail is a device used to guide and support the movement of objects. It is usually made of metal or other materials and features high precision, high rigidity and low friction.

[0003] Guides can be divided into linear guides and rotary guides. Linear guides are used to achieve linear motion, such as machine tool worktables and conveyor devices in automated production lines; rotary guides are used to achieve rotary motion, such as rotary worktables and rotary shafts.

[0004] There are sliding guides, rolling guides, and hydrostatic guides, among others. Sliding guides achieve movement through sliding friction between the slider and the guide rail; they have a simple structure but a relatively high coefficient of friction. Rolling guides utilize balls or rollers rolling between the guide rail and the slider; they have a low coefficient of friction and high motion accuracy. Hydrostatic guides achieve frictionless movement by forming a hydrostatic oil film between the guide rail and the slider; they offer advantages such as high precision, high rigidity, and high load-bearing capacity. In aerospace equipment such as aircraft and satellites, guides are used to achieve precise movement and positioning of various components.

[0005] Existing guide rail mechanisms mostly use gears and toothed rails to move the sliding block on the guide rail. This type of guide rail requires high processing costs for gears and toothed rails, and mainly moves by sliding, which consumes a lot of energy. Therefore, there is a need for a low-cost device that is easy to control the movement of the sliding block. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a linear intelligent guide rail mechanism for aerospace equipment.

[0007] The technical solution of this utility model is: a linear intelligent guide rail mechanism for aerospace equipment, including a sliding groove, a sliding block slidably connected in the sliding groove, a movable pulley at the front end of the sliding block, a fixed pulley on each side of the front end of the sliding groove, a wire control mechanism one on each side of the outer wall of the sliding groove, a steel rope one wound around the movable pulley, the two ends of the steel rope one respectively wound around the wire control mechanism one, a steel rope two fixed at the tail end of the sliding block, a wire control mechanism two at the rear end of the sliding groove, and the end of the steel rope two wound around the wire control mechanism two.

[0008] Furthermore, both the first and second wire control mechanisms include a rope winding wheel and a rope winding motor for driving the rope winding wheel to rotate, and the rope winding motor is fixedly connected to the outer wall of the sliding groove.

[0009] Note: By retracting steel rope one or steel rope two through a rope winding motor, the control cost of the wired control is lower than that of other telescopic structure control methods. The processing cost of this device is low, the sliding block moves quickly, and the moving position is more precise.

[0010] Furthermore, each of the inner walls on both sides of the sliding groove is provided with a snap-fit ​​groove, and the two sides of the sliding block slide within the snap-fit ​​groove.

[0011] Explanation: The snap-fit ​​groove increases the supporting force of the sliding groove on the sliding block, thereby increasing the load on the sliding block.

[0012] Furthermore, a roller is rotatably connected to the bottom of the sliding block, and the roller rolls at the bottom of the sliding groove.

[0013] Note: While ensuring that the load capacity of the sliding block does not decrease, using rollers can reduce the friction between the sliding block and the sliding groove, thereby reducing the energy consumption of the rope winding motor.

[0014] Furthermore, a PLC controller is provided on the outer wall of the sliding groove, and a laser ranging sensor for measuring the moving position of the sliding block is provided inside the sliding groove. The PLC controller is electrically connected to the laser ranging sensor, the first wire control mechanism, and the second wire control mechanism.

[0015] Explanation: The position of the sliding block in the sliding groove is detected by a laser rangefinder, and the moving speed of the sliding block is adjusted accordingly. When the sliding block is about to reach the target position, the speed can be reduced, so that the kinetic energy of the last part of the stroke can be recovered and reused, thereby reducing the energy consumption required for the sliding block to move.

[0016] The beneficial effects of this utility model are: This invention enables the sliding block to move within the sliding groove via wired control. The wired control method is simple in structure, low in manufacturing cost, and flexible in control. The sliding block responds quickly on the sliding groove. The use of rollers reduces the friction between the sliding block and the sliding groove. The guide rail mechanism of this invention has the advantages of low cost, low energy consumption, and high load capacity. Attached Figure Description

Detailed Implementation

[0020] Example 1: like Figure 1 As shown, a linear intelligent guide rail mechanism for aerospace equipment includes a sliding groove 1, a sliding block 2 slidably connected inside the sliding groove 1, a movable pulley 3 at the front end of the sliding block 2, a fixed pulley 4 on each side of the front end of the sliding groove 1, a wire control mechanism 5 on each side of the outer wall of the sliding groove 1, a steel rope 6 wound around the movable pulley 3, the two ends of the steel rope 6 respectively wound around the wire control mechanism 5, a steel rope 7 fixed at the tail end of the sliding block 2, a wire control mechanism 8 at the rear end of the sliding groove 1, and the end of the steel rope 7 wound around the wire control mechanism 8.

[0021] Both the first wire control mechanism 5 and the second wire control mechanism 8 include a rope winding wheel 51 and a rope winding motor 52 for driving the rope winding wheel 51 to rotate. The rope winding motor 52 is fixedly connected to the outer wall of the sliding groove 1.

[0022] By retracting steel rope 6 or steel rope 7 using a rope winding motor, the control cost of wired control is lower compared to other telescopic structure control methods. The processing cost of this device is also lower, and the sliding block 2 moves quickly and at a more precise position.

[0023] Example 2: The difference between this embodiment and embodiment 1 is that each of the inner walls on both sides of the sliding groove 1 is provided with a snap-fit ​​groove 11, and the two sides of the sliding block 2 slide within the snap-fit ​​groove 11.

[0024] Compared with Embodiment 1, this embodiment improves the supporting force of the sliding groove 1 on the sliding block 2 by using the snap-fit ​​groove 11, thereby increasing the load on the sliding block.

[0025] Example 3: The difference between this embodiment and embodiment 2 is that in this embodiment, the bottom of the sliding block 2 is rotatably connected to a roller 21, and the roller 21 rolls at the bottom of the sliding groove 1.

[0026] Compared with Embodiment 2, this embodiment ensures that the load capacity of the sliding block 2 does not decrease, while using the roller 21 can reduce the friction between the sliding block 2 and the sliding groove 1, thereby reducing the energy consumption of the rope winding motor 52.

[0027] Example 4: The difference between this embodiment and embodiment 3 is that the outer wall of the sliding groove 1 in this embodiment is also provided with a PLC controller 9, and a laser range sensor 91 for measuring the moving position of the sliding block 2 is provided in the sliding groove 1. The PLC controller 9 is electrically connected to the laser range sensor 91, the first wire control mechanism 5, and the second wire control mechanism 8.

[0028] Compared to Embodiment 3, this embodiment uses a laser rangefinder 91 to detect the position of the sliding block 2 in the sliding groove 1, and then adjusts the moving speed of the sliding block 2. When the sliding block 2 is about to reach the target position, the speed can be reduced, so that the kinetic energy of the last segment of the stroke can be recovered and reused, thereby reducing the energy consumption required for the movement of the sliding block 2.

[0029] The working method of Embodiment 4 above includes the following steps: S1. The rope winding motor 52 on the wire control mechanism 15 is started, which drives the steel rope 16 to wind around the rope winding wheel 51. The two wire control mechanisms 15 work at the same time, which can increase the speed of the sliding block 2 moving forward. The two wire control mechanisms 15 can share the pulling force required for the movement of the sliding block 2, and increase the load on the sliding block 2. The sliding block 2 is driven to move backward on the sliding groove 1 by the wire control mechanism 28. S2. By using the snap-fit ​​groove 11, the supporting force of the sliding groove 1 on the sliding block 2 is increased, and the load on the sliding block 2 is increased. While ensuring that the load capacity of the sliding block 2 does not decrease, the use of the roller 21 can reduce the friction between the sliding block 2 and the sliding groove 1, and reduce the energy consumption of the rope winding motor 52. S3. The rotation speed of the rope winding motor 52 is controlled by the PLC controller 9, and the real-time position of the sliding block 2 is detected by the laser range sensor 91. When the sliding block 2 is about to reach the target position, the speed can be reduced, so that the kinetic energy of the last stroke can be recovered and reused, thereby reducing the energy consumption required for the movement of the sliding block 2.

[0030] In the above embodiments, the rope winding motor 52, PLC controller 9, and laser rangefinder 91 are all commercially available products. As long as they can achieve the functions of this utility model, they are acceptable. Those skilled in the art can choose to use them based on common sense, and no special limitations are made here.
