Embodiment 1

[0027] Such as figure 1 As shown, this embodiment provides a functional motor built-in high-load and large-stroke push rod, including a base 1 and a driving mechanism arranged on the base 1, and the base 1 is provided with multiple layers of push rods that are sequentially sleeved The power transmission telescopic assembly, the driving mechanism is nested inside the push rod power transmission telescopic assembly and drives the push rod power transmission telescopic assembly up and down, and the driving mechanism adopts an embedded functional motor (or geared motor).

[0028] In this embodiment, the function motor built-in high-load and large-stroke push rod is suitable for various complex or simple technological processes, and has the advantages of structure, convenient installation, reliable use, simple maintenance, and energy saving. Compared with the hydraulic and pneumatic system, it not only saves the complicated system and reduces the weight, but also is not limited by ...

Embodiment 2

[0032] This embodiment is further optimized on the basis of embodiment 1, specifically:

[0033]The push rod power transmission telescopic assembly is a two-layer push rod power transmission telescopic assembly, and the push rod power transmission telescopic assembly includes a first layer of push rod assembly 10 and a first layer of push rod assembly 10 Inside the second layer of push rod assembly 9, the second layer of push rod assembly 9 is provided with an inner support sleeve 8 located above the drive mechanism 2, and the inner center of the inner support sleeve 8 is provided with a second layer of hollow transmission rod 7. The upper end of the first layer of hollow transmission rod 7 extends out of the inner support sleeve 8 and is fixedly connected with the second layer of push rod threaded sleeve 11. The second layer of push rod threaded sleeve 11 is threaded with the inner wall of the second layer of push rod assembly 9. 7. There is a first-layer transmission shaft 6...

Embodiment 3

[0041] This embodiment is further optimized on the basis of embodiment 1, specifically:

[0042] A flat pressure bearing A14 sleeved on the transmission shaft 6 of the first layer is arranged below the first layer of push rod threaded sleeve 12, and the flat pressure bearing A14 is located above the push rod assembly 9 of the second layer. The flat pressure bearing B15 set on the second layer of hollow transmission rod 7 is arranged under the threaded sleeve 11 of the push rod. The flat pressure bearing B15 is located above the inner support sleeve 8, and the inner top of the independent support protection frame 2 is set There is a flat pressure bearing C4 sleeved on the output shaft 5 of the motor 3 .

Abstract

The invention discloses a large-bearing-capacity large-stroke towing-shell type push rod with a built-in functional motor, relates to the technical field of electric push rods, and solves the technical problems that an electric push rod is large in size, a functional motor occupies a stroke space, and the single-layer stroke is limited. The push rod comprises a base and a driving mechanism arranged on the base; multiple layers of push rod power transmission telescopic assemblies which are sequentially arranged in a sleeving mode are arranged on the base, and the driving mechanism is embedded in the push rod power transmission telescopic assemblies and drives the push rod power transmission telescopic assemblies to ascend and descend up and down. According to the invention, the structure issimple, the embedded motor push rod is adopted to change the transmission structure of an original traditional external motor push rod, so the size is compact, the structure is simple, and configuration is more reasonable. Due to a fact that the embedded functional motor does not occupy the stroke space, the single-layer stroke is maximized, the embedded motor only provides rotating power and does not bear pressure and pull force, and therefore the push-pull force output bearing capacity can be large.

Description

technical field [0001] The invention relates to the technical field of electric push rods, and more specifically relates to a high-load-loading and large-stroke casing-drag push rod with a built-in functional motor, which is used for linear reciprocating motion of the push rod. Background technique [0002] The electric push rod is an electric drive device that converts the rotary motion of the motor into the linear reciprocating motion of the push rod. It can be used as an executive machine in various simple or complex processes to achieve remote control, centralized control or automatic control. control. The electric push rod is a general-purpose auxiliary drive device, which can be widely used in electric power, machinery, metallurgy, transportation, mining, petroleum, chemical industry, lifting, transportation, construction, grain processing and other industries. It has the characteristics of reliable performance, sensitive action, stable operation, equal push and pull ...
