Description

Technical Field

[0001] The utility model relates to the technical field of telescopic mechanisms, in particular to a servo telescopic mechanism. Background Art

[0002] The servo telescopic mechanism can accurately control position, speed and force, and is suitable for applications that require high-precision motion control. It can respond and adjust quickly, improve the dynamic performance and efficiency of the system, has a simple design and few parts, and a low failure rate, which improves the reliability and durability of the system. It can be used in various industrial and commercial applications, such as robotics, aerospace, manufacturing automation and other fields.

[0003] However, when the existing servo telescopic mechanism is in use, it is impossible to conveniently adjust the position of the wire rope to achieve uniform winding, which causes the wire rope to easily become scattered, thereby easily affecting the practicality of the servo telescopic mechanism. Utility Model Content

[0004] The utility model aims to provide a servo telescopic mechanism to solve the technical problem of the inconvenience of adjusting the position of the steel wire rope for uniform winding proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a servo telescopic mechanism, comprising a base plate and a support plate fixedly mounted on the base plate, a concave frame fixedly mounted on the back side of the base plate, a winding shaft is arranged inside the concave frame, a servo motor is fixedly mounted on the concave frame, and the output end of the servo motor is fixedly connected to one end of the winding shaft, a steel wire rope is wound around the winding shaft, a fixing frame is arranged on the base plate, and the steel wire rope is fixedly connected to the fixing frame, a square groove is fixedly mounted on the concave frame, a reciprocating screw rod is arranged inside the square groove, a slider is arranged inside the square groove, a threaded barrel is fixedly mounted inside the slider, and the reciprocating screw rod is threadedly connected to the threaded barrel, a limiting ring is fixedly connected to the slider, a driving motor is fixedly mounted on the square groove, and the output end of the driving motor is fixedly connected to one end of the reciprocating screw rod.

[0006] Preferably, a connecting frame is fixedly mounted on the fixing frame.

[0007] Preferably, a through groove is provided inside the support plate, a support wheel is movably provided inside the through groove, and the wire rope is located on the support wheel.

[0008] Preferably, a slot body is fixedly installed inside the concave frame, and a guide rod is fixedly installed inside the slot body.

[0009] Preferably, the guide rod passes through the slider.

[0010] Preferably, a cleaning ring is arranged inside the limiting ring.

[0011] Preferably, the cleaning ring is made of rubber.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model installs a reciprocating screw rod, which facilitates the servo telescopic mechanism to evenly wind up the wire rope. When the winding shaft rotates to wind up the wire rope, the wire rope passes through the limit ring, and the limit ring limits the wire rope, so that the operation of the driving motor drives the reciprocating screw rod to rotate, and the reciprocating screw rod causes the threaded barrel to move repeatedly, which in turn drives the slider to move synchronously, and the movement of the slider drives the limit ring to move synchronously. The repeated movement of the limit ring causes the wire rope to evenly wind around the winding shaft, and thus the wire rope can be evenly wound up, effectively avoiding the wire rope from being scattered, thereby improving the practicality of the servo telescopic mechanism.

[0014] 2. The utility model is convenient for removing impurities adsorbed on the surface of the wire rope by installing a cleaning ring. When the wire rope moves inside the limit ring, the cleaning ring contacts the surface of the wire rope, thereby removing the impurities adsorbed on the surface of the wire rope, thereby achieving the purpose of cleaning the impurities adsorbed on the surface of the wire rope, avoiding the adsorbent from being adsorbed on the surface of the wire rope for a long time and causing damage to the wire rope.

[0027] Working principle: first, use the servo telescopic mechanism to adjust the position of the tooling, and fix the tooling on the fixed frame 3 through the connecting frame 4. When it is extended or retracted, the servo motor 9 will work to drive the winding shaft 10 to rotate. When the winding shaft 10 rotates, the wire rope 5 will be reeled, and then the wire rope 5 will pull the fixed frame 3 when it moves. The movement of the fixed frame 3 will adjust the position of the tooling, so that the position of the tooling is extended or retracted, and the workpiece is processed. When the winding shaft 10 rotates to reel the wire rope 5, the wire rope 5 passes through the limit ring 18, and the limit ring 18 limits the wire rope 5, so that the driving motor 12 works to drive the reciprocating screw 17 to rotate, and the reciprocating screw 17 will make the threaded barrel 16 reverse The repeated movement will drive the slider 13 to move synchronously, and the movement of the slider 13 will drive the limit ring 18 to move synchronously. The repeated movement of the limit ring 18 will make the wire rope 5 evenly wound on the winding shaft 10, and then the wire rope 5 can be evenly wound, effectively avoiding the wire rope 5 from being scattered, and improving the practicality of the servo telescopic mechanism. When the wire rope 5 moves inside the limit ring 18, the cleaning ring 19 contacts the surface of the wire rope 5, and then the impurities adsorbed on the surface of the wire rope 5 can be removed, thereby achieving the purpose of cleaning the impurities adsorbed on the surface of the wire rope 5, avoiding the adsorbed objects from being adsorbed on the surface of the wire rope 5 for a long time and causing damage to the wire rope 5.
