Problems solved by technology

For large and medium-sized box parts, the bolts and nuts located at the opening of the box can be fastened conveniently and quickly by a single person; while the bolts and nuts located inside the box away from the opening are fastened due to human arm Length and tool restrictions and the interference of box parts make it difficult for one person to complete the fastening work. Often at least two people are required to cooperate to complete the bolt fastening work, which is time-consuming and laborious.

specific Embodiment approach 1

[0015] Specific implementation mode one: combine Figure 1 to Figure 6 Describe in detail the fastening transmission device for corner-type box parts, which is characterized by: including handle I (100) and handle II (300), elastic belt (200), active device (400), guide device (500), The tensioning device (600), the driven device (700); the handle I (100) and the handle II (300) are fastened and connected by bolts; the structure of the active device (400) and the driven device (700) Exactly the same, take the active device as an example: the active device (400) includes the pulley (401), deep groove ball bearing (402) and pin shaft (403), the pulley (401) and the outer ring of the deep groove ball bearing (402) Interference fit, interference fit between the inner ring of the deep groove ball bearing (402) and the pin shaft (403), the active device (400) is threadedly connected with the handle II (300) through the pin shaft (403); the guide device (500 ) includes the needle ro...

specific Embodiment approach 2

[0017] Embodiment 2: In combination with Embodiment 1, the fastening transmission device for corner-type box parts, its working principle is: use screws or magnetic adsorption to connect the sleeve with hexagonal holes or twelve-angle holes with the The pulley (401) of the driven device (700) is tightly connected, and the grooved circular plate with a shape of a word, cross, or four corners and hexagon is fastened to the pulley (401) of the driving device (400) by screws or magnetic adsorption. Connect the sleeve with the bolt and nut, and under the automatic adjustment of the tensioning device (600), use a wrench or a screwdriver to rotate the active device (400), and drive the driven device (700) to rotate through the elastic belt (200). Realize the tightening of bolts and nuts; when the bolts and nuts are tightened, the elastic belt (200) of the active device (400) will slip if the active device (400) continues to rotate, so as to avoid damage to the device due to excessive ...

Abstract

The invention discloses a capable-of-turning-angle type fastening transmission device of box-type parts. The capable-of-turning-angle type fastening transmission device includes a handle I, a handle II, an elastic belt, a driving device, a guide device, a tensioning device and a driven device. The elastic belt is wound around the driving device, the guide device, the tensioning device and the driven device in sequence, a wrench or a screwdriver is used for rotating the driving device, the driven device is driven by the elastic belt, and the driven device is connected with a bolt or a nut in abutting mode to realize tightening of the bolt and the nut; and when the bolt and the nut are tightened and overloaded, skid occurs between the elastic belt and a belt wheel so as to avoid damage to the fastening transmission device due to excessive tightening of the bolt and the nut. The capable-of-turning-angle type fastening transmission device can be used for fastening bolts and nuts located in the box-type parts, especially large and medium box-type parts, and can be matched with bolts and nuts of different models by replacing six point sockets. The capable-of-turning-angle type transmission scheme can greatly reduces the interference in a linear transmission scheme, so that the bolt fastening in the box-type parts is more convenient and faster.

Description

technical field [0001] The invention relates to a fastening transmission device, in particular to a fastening transmission device for corner-type large and medium-sized box parts, belonging to the field of mechanical engineering. Background technique [0002] In daily production and life, when large and medium-sized box parts are used together with other parts, they are often connected by bolts. For large and medium-sized box parts, the bolts and nuts located at the opening of the box can be fastened conveniently and quickly by a single person; while the bolts and nuts located inside the box away from the opening are fastened due to human arm The length and limitation of tools and the interference of box parts make it difficult for a single person to complete the fastening work. Usually at least two people are required to cooperate to complete the bolt fastening work, which is time-consuming and laborious. Contents of the invention [0003] In view of the above problems, ...
