Description

Flexible and multipurpose fixed pulley

Technical Field

The utility model relates to a production line technical field especially relates to a nimble multi-purpose fixed pulley.

Background

In an automobile welding workshop, resistance welding is a main technological means during automobile body assembly, and a resistance spot welding process is largely adopted in the welding of parts such as an automobile body bottom plate, a side wall, a frame, a roof, a door, an automobile body assembly and the like. A suspension type spot welder is one type of resistance welding spot welding. Generally, automobile welding factories in long-term ages commonly adopt split type welding tongs for spot welding, and the welding tongs are divided into an X type and a C type according to the action of a welding arm, but due to the characteristic of the structure of parts of each sub-assembly of a body-in-white, operation staff is required to perform action requirements such as welding tongs overturning, large-angle rotation and the like, and an auxiliary tool with a fixed pulley structure is required. Meanwhile, in many aspects of a welding workshop, a heavy object needs to be lifted, or certain large-scale equipment needs to be maintained and lifted, and an auxiliary tool with a fixed pulley structure also needs to be used. In order to match with the flexible rotation of an operator or the flexible hoisting of a heavy object, a flexible and multipurpose fixed pulley structure is needed to realize the flexible and multipurpose fixed pulley structure.

SUMMERY OF THE UTILITY MODEL

The utility model discloses fully considered advantages such as structural practicability is strong, structural diversity, usage are extensive, operation aspect, the present invention provides a nimble multi-purpose fixed pulley structure, solved and to have satisfied staff's operation wide-angle rotation's demand, can also apply other places simultaneously and carry out the heavy object and lift by crane, realized structural usage extensively in a flexible way, the variety. The specific technical scheme is as follows:

a flexible and multipurpose fixed pulley comprises an L-shaped connecting block a and an L-shaped connecting block b which are symmetrically arranged, wherein the inner sides of one ends of the narrow surfaces of the L-shaped connecting block a and the L-shaped connecting block b are connected with a rotating wheel through bolts, and the outer sides of the L-shaped connecting block a and the L-shaped connecting block b are locked and fixed through nuts; the T-shaped connecting block is fixedly connected with the L-shaped connecting block a and the L-shaped connecting block b through four connecting nuts, and a threaded hole is formed in the middle of a boss of the T-shaped connecting block.

Furthermore, an elastic pad is arranged on the inner side of the nut close to the L-shaped connecting block.

Furthermore, the height of the boss exceeds the height of the end face of the four fastening nuts.

Furthermore, the size of the threaded hole is matched with the size of the connecting thread of the corresponding connecting hanging ring.

The beneficial effects of the utility model reside in that: simple structure, quick installation, strong interchangeability, strong structural practicability, wide application and the like.

Detailed Description

The invention is further described below with reference to the accompanying figures 1-2 of the specification:

a flexible and multipurpose fixed pulley comprises an L-shaped connecting block a2 and an L-shaped connecting block b 6 which are symmetrically arranged, wherein the inner sides of one ends of the narrow surfaces of the L-shaped connecting block a2 and the L-shaped connecting block b 6 are connected with a rotating wheel 7 through bolts 1, and the outer sides of the narrow surfaces of the L-shaped connecting block a2 and the L-shaped connecting block b 6 are locked and fixed through nuts 9; the T-shaped connecting block 3 is arranged at one end of the wide surface of the L-shaped connecting block a2 and one end of the wide surface of the L-shaped connecting block b 6, the T-shaped connecting block 3 is fixedly connected with the L-shaped connecting block a2 and the L-shaped connecting block b 6 through four connecting nuts 4, and a threaded hole 10 is formed in the middle of a boss 5 of the T-shaped connecting block 3. And an elastic pad 8 is arranged on the inner side of the nut 9 close to the L-shaped connecting block. The height of the boss 5 exceeds the height of the end face of the four fastening nuts 4. The size of the threaded hole 10 is matched with that of the corresponding connecting hanging ring connecting thread.

The working principle is as follows: the suspension welding machine welding gun needs large-angle rotary welding, the suspension welding machine is mounted, the threaded hole in the boss 5 is connected and locked through the circular connecting hanging ring, and the welding tongs are suspended to rotate at a large angle through the rotating wheel, so that the operation of workers is facilitated; the invention is used for hoisting, the threaded holes on the bosses 5 are used for fixing, connecting and locking bolts, and the pulley principle is used for changing the direction of the force of the heavy object for hoisting.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
