Problems solved by technology

Due to the large size and length of the drive chain, even if the tensioner is loosened, it is difficult to keep the chain in a slack state
Especially when replacing chain links, the connection of the last two chains is the most difficult, and the disconnected part of the chain must be shrunk to a connectable state with the help of a manual hoist, which is not only cumbersome and labor-intensive, but also takes a long time Conducive to rapid repairs, will affect the efficiency of automobile production

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the drawings and embodiments:

[0019] Such as figure 1 , figure 2 As shown, the present invention is composed of a first grapple hook 1, a second grapple hook 2, a first balance arm 3, a second balance arm 4, a bracket 6, a nut sleeve 7, and a tension screw 8 and other components. Among them, the first grapple hook 1 and the second grapple hook 2 are both flat-plate structures with a small top and a large bottom, and the first grapple hook 1 and the second grapple hook 2 are arranged symmetrically. Two balance arms are provided between the first grappling hook 1 and the second grappling hook 2, which are a first balance arm 3 and a second balance arm 4 respectively, and the first balance arm 3 and the second balance arm 4 cross each other. The left end of the first balance arm 3 is hinged to the top end of the first grappling hook 1 through a pin, and the right end of the first balance arm 3 is hin...

Abstract

The invention discloses a chain maintenance device. A first grapple (1) and a second grapple (2) are symmetrically arranged on the left and right, and crossed between the first grapple (1) and the second grapple (2). The first balance arm (3) and the second balance arm (4), the bottom ends of the first grapple (1) and the second grapple (2) are provided with a hook head (5), and one of the grapples The lower part of the hook is fixed with a bracket (6), and the lower part of the other grapple is fixed with a nut sleeve (7). The bracket (6) is rotatably connected to the tightening screw (8), and the tightening screw (8) can (6) Rotate on the spot, and the nut sleeve (7) is threadedly matched with the tightening screw rod (8). The invention has the advantages of simple structure, convenient operation and labor saving, which can facilitate the repair and maintenance of the drive chain of the plate chain production line, save the time for emergency repair of the chain, and provide guarantee for the normal progress of automobile production.

Description

Technical field [0001] The invention belongs to the technical field of tooling and fixtures, and specifically relates to a device for chain maintenance. Background technique [0002] The plate chain production line is a commonly used production line for vehicle assembly and body adjustment during the production of automobiles. This type of production line is large in scale and long in production. It is more practical in production, but it is not very convenient in repair and maintenance, especially the repair of drive chains. And maintenance is particularly difficult. The drive chain is the main drive link that transfers the power from the drive motor to the floor chain. It is an endless chain installed under the floor chain. There are circular toothed wheels at both ends of the endless chain, one end is the driving wheel connected with the driving motor, and the other end is the driven wheel connected with the chain tensioner. In order to ensure the smooth running of the floor...
