Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical transmission technology, specifically a high-frequency response actuator driving linkage mechanism. Background Technology
[0002] High-frequency response actuator-driven linkage mechanism is a technology that uses a high-frequency response actuator to drive a linkage mechanism. This mechanism is usually composed of rigid components connected by hinges or sliding pairs, and is mainly used to transmit motion and power. Traditional linkage mechanisms suffer from response delay and decreased accuracy due to problems such as large inertia and insufficient rigidity during high-frequency motion. Existing connection methods between actuators (such as motors, hydraulic cylinders, and pneumatic cylinders) and linkages have transmission loss or resonance problems.
[0003] To address the issue of insufficient high-frequency response performance in existing linkage mechanisms, this invention optimizes the connection structure between the actuator and the linkage, reduces the mass of moving parts, and achieves rapid start-stop and stable transmission at high speeds. Utility Model Content

[0006] The actuator drive linkage device includes a high-frequency actuator, which is located below the base. The high-frequency actuator has a hinge seat 1 at both its output end and end end. A main connecting rod is movably connected to the inner side of each hinge seat 1. A weight-reducing groove is formed on each main connecting rod.

The internal structure of the hinge seat 2 and hinge seat 3 is the same as that of the hinge seat 1.
[0007] In the above technical solution, the shaft pin, snap ring, snap groove and flange are set. By removing the screws on both sides, the shaft pins at both ends can be separated, realizing the disassembly and assembly of the actuator and the main connecting rod. This facilitates the maintenance and replacement of worn connecting rods and shortens the maintenance time of the actuator.

[0010] As a further preferred embodiment of this technical solution, guide rods are provided above the front and rear ends of the bracket, and the through holes around the connecting plate are slidably connected to the guide rods.
[0011] In the above technical solution, the connecting plate is slidably connected to the guide rod through a drive, and has rigid guiding and anti-eccentric load capabilities.
[0012] As a further preferred embodiment of this technical solution, the main connecting rods all adopt a lightweight hollow structure, and lubricated bearings are provided at the hinges.
[0013] In the above technical solution, the main connecting rod adopts a hollow structure to reduce the inertia of moving parts and improve the response frequency of the mechanism. The hinge is connected to the driven rod through a flexible hinge to reduce friction loss. The structure is compact, improves transmission efficiency, and is easy to integrate into automated equipment.
[0014] As a further preferred embodiment of this technical solution, a flange is fixedly connected to one end of each of the outer sides of the shaft pin, and the flange is connected to the screw hole by screws.
[0015] The above technical solution facilitates the subsequent separation of the pins at both ends.
[0016] As a further preferred embodiment of this technical solution, a polyurethane gasket is provided on the outer surface of the side of the flange that contacts the hinge seat to suppress high-frequency vibration.
[0017] This utility model provides a high-frequency response actuator driving linkage mechanism, which has the following beneficial effects:
[0018] (1) The present invention adopts a hollow structure for the main connecting rod, which reduces the inertia of the moving parts and increases the response frequency of the mechanism.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown in this embodiment, a high-frequency response actuator drive linkage mechanism includes a base 1, two bases 1 are symmetrically arranged, and a bracket 2 is fixedly connected to both ends of the base 1. An actuator drive linkage device 4 is installed at one end of each of the two brackets 2 facing each other. A guide rod 3 is provided above the front and rear ends of the bracket 2. The connecting plate 47 is slidably connected to the guide rod 3 through the surrounding through holes. The connecting plate 47 is slidably connected to the guide rod 3 by driving, which has rigid guidance and anti-eccentric load capacity, and avoids the linkage from being deformed by lateral force.
[0027] like Figure 3 and Figure 4As shown, the actuator drive linkage device 4 includes a high-frequency actuator 41, which is located below the base 1. Both the output and end ends of the high-frequency actuator 41 are provided with hinge seats 42. Main connecting rods 43 are movably connected to the inner side of each hinge seat 42. The main connecting rods 43 all adopt a lightweight hollow structure, and lubricated bearings are provided at the hinge points. A second hinge seat 44 is movably connected to the middle of each main connecting rod 43. The second hinge seat 44 is fixedly connected to the bracket 2. The upper end of the main connecting rod 43 is movably connected to the second hinge seat 44. A driven rod 45 is connected to the main connecting rod 43. The other end of the driven rod 45 is hinged to a hinge seat 46 via a flexible hinge. Both hinge seats 44 and 46 have the same internal structure as hinge seat 42. A connecting plate 47 is provided on the outer side of hinge seat 46. Weight reduction grooves 431 are provided on the main connecting rod 43. By adopting a hollow structure, the inertia of the main connecting rod 43 is reduced. Through optimized design, the weight is reduced compared to traditional connecting rods. The hinge is connected to the driven rod 43 via a flexible hinge. This design reduces friction loss, features a compact structure, improves transmission efficiency, and facilitates integration into automated equipment. Both ends of the hinge seat 42 are secured with pins 422. A retaining ring 423 is fixedly connected to the inner side of one pin 422, while a retaining groove 424 is formed on the inner side of the other pin 422. The retaining ring 423 inserts into the retaining groove 424. Screw holes 421 are formed on the circumferential direction of the outer surfaces of both sides of the hinge seat 422. A flange 425 is fixedly connected to one end of each pin 422. The flange 425 is connected to the screw holes 421 by screws. A polyurethane gasket is provided on the outer surface of the flange 425 that contacts the hinge seat 422 to suppress high-frequency vibration. By removing the screws on both sides of the pins 422, retaining ring 423, retaining groove 424, and flange 425, the pins 422 at both ends can be separated, allowing for the disassembly and assembly of the actuator and the main connecting rod 43. This facilitates maintenance and replacement of worn connecting rods, shortening actuator maintenance time.
[0028] This utility model provides a high-frequency response actuator driving linkage mechanism. The specific working principle is as follows: The high-frequency actuator 41 is sleeved on the shaft pins 422 at both ends. The shaft pins 422 at both ends are engaged together by the snap rings 423 and snap grooves 424, and the flange 425 is connected to the screw hole 421 by screws. When it is necessary to maintain or replace the worn linkage, the screws on both sides are removed to separate the shaft pins 422 at both ends, so as to realize the disassembly and assembly of the actuator and the main linkage 43. The main linkage 43 adopts a hollow structure to reduce the inertia of the moving parts and improve the response frequency of the mechanism. The hinge is connected to the driven rod 43 by a flexible hinge to reduce friction loss.
